In order to enable middle and junior electronic technicians to develop GSM SMS alarm products, our factory organized many electronic technical engineers to jointly develop the JB35G multi-function GSM SMS module in 2000. After 8 years of production, sales and improvement, it has developed into multiple models of JB35G series. The JB35G module can be said to be a special SMS module for alarms. Many functions in the module are specially designed for making anti-theft alarms. It does not require external single-chip microcomputers, as long as power and alarm probes are added to form a wireless GSM alarm. Even junior electronic technicians can use it to make very professional, stable and reliable car GSM anti-theft alarms, home GSM anti-theft alarms, computer room monitoring alarms and other products.
Suitable for the development of multi-function alarm monitoring systems, such as: wireless GSM home anti-theft alarm system, short message temperature telemetry and remote transmission system, GPS vehicle remote positioning system, SMS advertising mass sender and other fields
The advantages of using JB35G to develop home GSM alarms: common home anti-theft alarms are all dialed through the telephone line, but fixed telephone wiring boxes are generally placed in the corridors of residential buildings. If the thief enters the room, first open the wiring If the box breaks the telephone line, the system cannot call the police. If you use the family GSM anti-theft alarm developed by JB35G, you can completely avoid the possibility of being destroyed, greatly increasing the reliability and safety of the alarm.
Advantages of using JB35G to develop car GSM alarm: send the car alarm message directly to the user's mobile phone, you can monitor your car in any corner of the world, completely solve the problem that you can't hear the car alarm sound in high-rise residential buildings or shopping malls Contradiction. You can also use a mobile phone to remotely control fuel and power out of a stolen car. The base station positioning function using the mobile phone SIM card can also be large enough to determine the location of the stolen car. Using JB35G to send out text messages or dial phone calls to the alarm, there can be no sound at the scene, completely solve the problem of alarm noise and disturbing people when the car is parked in the residential area, and truly achieve environmental protection.
Features of JB35G series SMS module
1. The module can directly drive 8 relays. The 8-channel relay can be controlled by SMS remote control, SMS timing remote control, DTMF remote control, and ringing remote control.
2. It has the function of SMS remote control result return. After receiving the remote control short message, the module can still send back the control result in the form of short message.
3. There is a caller number filter to reject the illegal mobile phone remote control module relay, so that your mobile phone has the role of remote control "ID card".
4. The design idea of ​​the module is based on humanity, using intuitive Chinese as the SMS remote control instruction and alarm SMS content, and the user can customize it.
5. 20 alarm message contents and mobile phone number can be pre-stored in the module, which can be sent correspondingly under the trigger of wired or wireless sensors.
6. 12 wireless alarm defense zones (need to add 315M decoding receiver board on the expansion pin of JB35G).
7. 8 wired alarm zones, using upper and lower edge transitions to trigger alarms, suitable for any sensor.
8. After each wired and wireless alarm zone is triggered, it can send alarm messages to 6 mobile phones at the same time and make alarm calls to 6 mobile phones.
9. The setting of alarm message content and number can be rewritten by computer software, or can be rewritten by mobile phone text message.
10. The arming / disarming control pin controls the arming and disarming of 12 wireless defense zones and 8 wired defense zones through external high and low levels.
11. The module can be armed, disarmed, semi-armed, and forbidden by the handheld remote control (requires additional 315M receiving board and remote control).

17. Caller ID number can be output through the serial port.
18. The operating voltage is powered by 12V DC, which is compatible with automotive power supply systems.
19. With ringing remote control function free of call charges. Under the trigger of the caller ID and ringing sound when making a call, the state of the relay is reversed.
20. JB35G is equipped with a short message measurement A / D conversion board, which can send the 5-channel temperature data and 8-channel voltage data collected on the spot to your mobile phone in the form of a short message to realize remote roaming monitoring.
Typical application of JB35 module:
1. Mobile phone controlled access control system:
The eighth way of JB35 is used to control the electric control lock of the access control system, and the eighth way control output is set to automatically turn off after 3 seconds, and the ringing remote control is set to only the following 6 numbers to achieve ringing remote control. If you need to enter the door, just dial the mobile phone card number in the JB35 module with your mobile phone, hang up after hearing 2 ringback tones, the door will automatically open, and only the mobile phone number you set can open the door, and there is no charge.
2. Emergency closing of disaster weather when turning over three billboards:
The three-fold billboard is realized by a motor that continuously flips and displays multiple advertisement contents. Because it is installed outdoors, the billboard is easily blown out or stuck and damaged when there is a stormy weather such as high winds or hail. The first control output can be set to automatically turn off after 26,987 seconds, and the relay's normally closed contact is used to control the power of the billboard. At this time, you only need to send the "open first" control message, the billboard It will automatically shut down, and automatically resume normal work after an automatic delay of 26987 seconds (generally disastrous weather will not last very long). If you want to open the billboard in advance, you can send a "close the first way" control SMS, if you think Controlling text messages is not intuitive enough, you can also modify the “open first way†control text message to “emergency close billboard†in the dedicated software, and change the “close first way†control text message to “open billboardâ€
3. Reminder of the remaining balance of the engineering system:
Some projects are completed after a safe operation and normal operation for a period of time before the balance is cleared. If you encounter a customer who defaults on the payment, it is often a headache for the installer, because the equipment has been installed and if it is removed, the loss will be very large, especially the foreign customers are very laborious. At this time, we can install our JB35 module in the customer system first, and use some key points of its one-way or multi-way control system. When the customer maliciously defaults on the payment, he can close some functions through SMS, forcing the customer to pay the payment and then SMS immediately. After opening, if the payment has been successfully recovered, the JB35 can be removed from the customer system in the name of system maintenance.
4. Alarm and reset of monitoring system or website server:
The monitoring system or website server may crash after a long period of operation. At this time, power-off reset is the only solution. At this time, the power of the system can be controlled by JB35, and it is set to automatically turn off after 3 seconds. Electrical reset, the JB35 module has a 1-port alarm function. The short circuit of the 12th pin to ground can realize the function of sending alarm messages and dialing calls. If the system itself has a fault status output function, it can automatically alarm, and then remotely reset after receiving the alarm. The JB35G module is also equipped with an 8-port alarm function, which can realize multiple alarm messages, such as: main power disappears, memory errors, cooling fan shutdown, fuel exhaustion, intrusion, etc., which is ideal for drone room monitoring select.
5. Remote control of home appliances:
It is easy to remotely turn on home appliances such as rice cookers and water heaters through SMS control. You can also control the air conditioner by controlling the remote control or switching to the maintenance mode.

<3> Turn on the 12V regulated DC power supply. (If you drive 8 relays, you must ensure that the output current of the regulated power supply is ≥1000mA and the transformer power is ≥10W.)
<4> If it is the first time to turn on the power, you must wait for 20 seconds to 10 minutes before the LED0 light is on and enter the standby state. If the power is turned on after the second time, you only need to wait for 20 to 30 seconds, the LED0 light-emitting tube lights up and enters the standby state. (During this waiting time, JB35 will first search the GSM network and then the SIM card formatting process. The GSM network search will take about 20 to 30 seconds. The SIM card formatting process will take about 1S to 10 minutes. Format the SIM card The purpose is to delete the contents of the phone book and short message box in the SIM card, because these storage spaces are used by JB35 to store some important data in operation. The length of the formatting time depends on the content of the phone book. If the content of the book is empty, it only takes 10 seconds to complete the formatting.) After the network is successfully logged in, LED0 will turn on constantly, and a green patch LED on the mobile phone module will also flash at a frequency of 0.5HZ, indicating network connection success.
Function 1: SMS remote control
<5> After entering the standby state, use another mobile phone to send a short message to the SIM card number on JB35, the content is "open the first road, open the second road, open the third road, open the fourth road, open the first Five channels, turn on the sixth channel, turn on the seventh channel, and turn on the eighth channel. "After the JB35 receives the message, the LEDs LED1 ~ LED8 should be all bright. If there is a relay connected, all 8 relays should be switched on. Send another short message, which reads: "Close the first way, close the third way." After JB35 receives it, LED1 and LED3 light-emitting tubes are off, the relay is released, this is the SMS remote control function. "Open the first way, open the second way ..." These are the default SMS remote control instructions, the specific instructions can refer to JB35G special setting software V5.0, the factory default is "open the X (Chinese one to eight) road" Or "Closing the Xth Road (one to eighth in Chinese)".
Of course, you can also replace the short message remote control command with a phrase you need. For example, the first relay is used for remote air conditioning operation. You can set it to "turn on the air conditioner" or "turn off the air conditioner". This requires running the JB35G special setting software V5.0 for setting, which will be described in detail in the following JB35G special setting software V5.0.
Function 2: Device status SMS return
Many times after we send the SMS remote control command, we want to know whether the device has been executed immediately. At this time, we can use our "device status SMS return" function to achieve, as long as we send a "status query" SMS remote control command, wait Within a few seconds, you will receive a short message detailing the actual status of whether the current 8-way device has been turned on or off. Or we only need to add a "?" When sending a short message command to let the system automatically reply to a status message at the same time as the remote control device. For example, we send out: "Open the fifth way?" Control SMS, the system will It can automatically open the fifth road, and automatically reply an "open fifth road" to indicate that the fifth road has indeed been opened.
Function 3: Ringing remote control
<6> Use your mobile phone or phone to dial JB35, and JB35 will ring. You should also hear the ringback tone "beep-beep" in the handset, and hang up immediately after hearing two ringback tones. The eight-way LED8 green patch light-emitting diode tube should be lit, and the eighth-way relay should be switched on. JB35 is called again. After two beeps-beep, it hangs up again. LED8 is off and the relay is released again. This is the ringing remote control. Its main feature is that both parties to the call can reach the purpose of remote control without entering the call state. It is a completely free control method.
The ringing remote control has a caller ID phone number filter. The filter function is temporarily disabled at the factory, so that when the phone is turned on, all the phones can dial JB35 to ring the remote control. However, in practical applications, we need to reset the ringing remote filter through the JB35G special setting software V5.0 introduced below, so that only 1 to 6 specific phone numbers can be used to ring remotely control the JB35, while other phones When calling, the ringing remote control function is invalid. Can increase the safety and reliability of the system. This function is implemented using the mobile phone caller ID function.
Function 4: DTMF call remote monitoring
<7> After dialing JB35 with a telephone, after hearing 4 ~ 5 ringback tones, JB35 can be connected automatically. After connecting, on the telephone keypad "1 *", the first relay should be switched on, press "2 *" the second relay to switch on ... Press "8 *" the 8th relay to switch on. Press "1 # first relay to close ... Press" 8 # "eighth relay to close. This is DTMF remote control, also called call remote control. In addition, press" 0 * "to hear the sound around JB35 Monitor function. Press "0 #" to turn off the monitor function.
Function 5: output mode selection
The default output mode of the 8-channel output is the bistable mode, that is, the output state of the remote control is changed once. In fact, we can also use the JB35G special setting software V4.2 to set the output to a few seconds after turning on the X-way switch After disconnecting, this can be used for automatic remote reset of some devices, which is very practical.
Function 6: The 12th foot button triggers to send a short message
There is a button on the 4 relay extension board. Once this button is pressed, JB35 can automatically send a pre-arranged short message, such as "The safe door is opened!" This can be used in some anti-theft alarm occasions, such as through vibration The sensor or door magnetic switch triggers JB35 to automatically send an alarm short message. In the JB35 special software, it can be set to send only short messages or only make calls or send short messages and make calls when alarming. One advantage of short message is that even if the other party's mobile phone is in a call, the short message can be received in real time, and it will not be unable to connect because of the busy line like the phone, delaying the alarm.
Installation and operation of JB35 SMS remote control setting software
Through the setting of JB35 special software, you can make the function of JB35 meet the requirements you want, and can set up control instructions with your own personality. The JB35 configuration software must be installed before use.
<1> After downloading the JB35G special setting software V5.0 file downloaded from the Internet with the WINRVR decompression software, double-click the JB35.EXE file directly to avoid installing and running the setting software. Or put the CD attached with JB35 into the CD-ROM drive, enter the "JB35 Setup Software" in the CD, and run Setup.exe to install.
<2> After the installation is complete, enter the directory of the installed hard disk, run "JB35.exe" to enter the setting software interface. You can also run "Start" / "Program" / "JB35 JB35G SMS Remote Control Setting Software V2.2" to enter the interface.
〈3〉 If JB35 has not been powered on, please follow the previous steps to start up and enter the standby state. Then plug the serial cable attached to JB35 into the serial port of the computer Com1 or Com2, and plug the other end of the serial cable into the RS232 serial port of JB35.
After entering the JB35 / JB35G setting software interface, we can see that there are 9 pages of tabs at the top of the software, which looks a bit like "bookmarks", each tab has a book signature, they are "version query", "message remote Settings "," DTMF Remote Control Settings "," Ring Remote Control Settings "," Output Settings "," SMS Data Transmission Settings "," Alarm Settings (1) "," Alarm Settings (2) "and" Exit ". Just open the software, the interface selects the first page "version query" by default.
We can use the mouse to click on other book signatures to switch the interface to the corresponding interface. 8 different interfaces are used to set the functions of 8 different function modules of JB35 / JB35G. If you want to exit the setting software, you can click "Exit" to sign the book.
There is online help in the 8-page function setting interface of the setting software. The help text is placed in the free space of each interface in red on a yellow background. The help text can guide you how to set the parameters of this page correctly, and introduce the use and purpose of some functions of this page. In order to make the user clear at a glance, we also added the contents of the instruction manual to the online help on each page. It is recommended that interested customers can run this software to read it carefully.
The internal structure circuit of JB35G's 8-channel wired alarm input is shown in figure (3) 
The 15th, 16th, and 17th pins of JB35G adopt the rising edge of the level transition from low level to high level as the alarm trigger condition. These ports are suitable for connection: wired door sensor, wired infrared, disconnection sensor, etc. . Because these sensors usually use normally closed output, which is normally short-circuited and closed, when the door is opened, someone invades, and the detection line is broken, it becomes an open circuit. The advantage of using normally closed output is that multiple wired sensors can be connected in series , Saving wire and wiring convenience.
For example, the connection of the disconnection alarm is shown in figure (4). Usually the alarm input pin is connected to low level by the wire 0 and no alarm. When the wire is broken by the thief, the alarm input pin is pulled to high level by the internal 100K pull-up resistor At the moment of 1, a 0-1 rising edge transition is formed, and JB35G sends out an alarm message. After the alarm, the input pin is still high level 1, the system does not alarm. Only when the alarm input pin is connected to low level 0 and then disconnected, will the alarm be triggered again. Inside the wired door sensor is a dry reed pipe, and its connection is affected by the external magnet. The connection method is exactly the same as the disconnection alarm, which is a rising edge transition alarm.
The 11th, 12th, 14th, 18th and 19th feet of JB35G adopt the falling edge of the level transition from high level to low level as the alarm trigger condition. These ports are suitable for connecting vibration sensors, microwave sensors, For smoke sensors, gas sensors, emergency buttons, etc., see the connection (five).
The advantage of sampling rising edge transition or falling edge transition to trigger an alarm is that it does not alarm no matter when it is at low level or high level, which can prevent the same alarm message from being sent blindly. In addition, the rising edge transition can also be directly connected to the wired gate Magnetic and wire break sensors do not require additional power and control circuits.
Questions and answers about the application of JB35G module:
1. Can JB35G be used as an SMS chatter?
Answer: JB35G can send and receive Chinese text messages of any content, so it has this function, and we have also developed a special software for SMS computer chatter for PC, the interface is similar to QQ, customers can download and use, so sending and receiving SMS is very convenient and fast.
2. How reliable is the JB35G module?
Answer: This question is more difficult to answer, because any complex system will be affected by many factors. For example, the WINDOWS system, which costs a lot of money, will still crash after many years of improvement. If the latest mobile phone is turned on for 24 hours, it will also appear after a certain period of time. Crash, our system is also a complex system, including GSM part and multiple microcontroller systems, and is also subject to strict cost constraints, objectively speaking, it may also malfunction, we recommend that if your system needs 24 hours of continuous work, the most Fortunately, power off and restart once every one week or so, this can improve the stability of the system. Our JB35 series products have been developed for more than 3 years. During this period, we have continuously improved hardware design and software anti-death processing. Both the functional design and the convenience of use are constantly improving and improving. At present, we have long-term cooperation with many manufacturers to provide sources of supply.
3. What are the advantages of purchasing JB35G?
Answer: JB35G module is currently the most powerful and cheapest GSM module in China. Compared with the most commonly used Siemens TC35I module, it is not only expensive, but also must be proficient in AT commands, and must be very proficient in achieving many of our JB35 functions. SCM technology and product anti-interference and anti-death technology are not the technical capabilities possessed by ordinary small factories.
4. Are there any charges when the JB35G module is used normally? How to minimize costs?
Answer: The SIM phone card must be inserted when the JB35G module is working normally. You can purchase a mobile phone card with no monthly fee. The module does not have a fee when it receives control text messages. It is the same if you want to send back text messages or send text messages. There is a short message fee. If the module uses the ringing remote control function to remotely control the relay, there is no fee. If you use DTMF remote control or monitor the environmental sound, there will be a call fee. The module will not have a fee during normal standby.
5. What is the computer-free SMS setting function of the JB35 module?
Answer: It is very convenient and quick to set the comprehensive function of the JB35 module with a computer, but it is very likely that there is no computer at the installation site of the module. We have created the mobile phone SMS setting function, which allows customers to accurately control the function of the module by sending control SMS. Set up is very convenient.
In the "Alarm Settings (1)" in the setting software, you can set 4 Chinese words for JB35 / JB35G as security secret words. As long as you remember this security secret word, you can change the JB35 by texting at any time through your mobile / JB35 alarm settings. The default cipher language at the factory is: SMS rewriting, the user can change to four other Chinese cipher words of any content.
