The drone entering the airport not only caused delays in flight landings, but also seriously threatened aviation safety. This phenomenon has occurred frequently in various airports with the increase of the phenomenon of "black flying" of drones.
The "Daily Economic News" reporter found that in the first half of this year, the Civil Aviation Administration received a total of 44 reports on flight operations affected by drones, an increase of 37 cases, and 790 affected flights, an increase of 689 classes.
On November 23, the country's first airport "UAV detection and defense system" was put into trial operation at Baiyun Airport (600004, SH). It is understood that the system can be found and accurately positioned within 3 seconds after the drone is turned on, and implements precise electromagnetic interference to realize drone driving and forced landing in the control area, and the detection range reaches 13 kilometers in diameter.
Relevant persons at Baiyun Airport said that the UAV detection and defense system can quickly detect and control drones, ensure the safety of the perimeter of the airport, and increase the "technical defense" means for drone control.
Can be positioned after 3 seconds of booting
On November 23, Baiyun Airport announced that it was the first “National UAV Detection and Defense System†consisting of two parts: “defensive detection and early warning system†and “unmanned aircraft interference system†(hereinafter referred to as Cang).擒 system) officially put into trial operation.
According to the introduction of Baiyun Airport technical personnel, the "defensive detection and early warning system" determines the position of the drone by receiving the drone map transmission and remote control signals, without waiting for the drone to be lifted, within 3 seconds after the drone is turned on. It can be found and accurately positioned; the UAV Interference System automatically adjusts the frequency and direction of the electromagnetic interference, and implements precise electromagnetic interference according to the detected operating frequency and direction of the UAV, realizing no one in the control area. The machine drove away and forced to land. It can realize the monitoring, discovery and tracking of UAVs with a diameter of 8 km, and its effective range can reach 13 km in diameter in an open environment.
"Daily Economic News" reporter learned that at present, the Cangwu system has completed the pilot installation and commissioning of the first set point in the airport, and can be used for the 8 km diameter of the southern end of the Baiyun Airport East Runway. Landing low-altitude airspace monitoring at this critical stage.
“Whether day or night or any weather, in any complex airport environment, (the sky system) can operate effectively. It can quickly find and control drones to ensure the safety of the airport.†The aforementioned Baiyun airport technicians introduced.
In addition, it is worth noting that, according to the analysis and evaluation of the Second Research Institute of the Civil Aviation Administration, the UAV interference equipment of the Cangwu system has basically no impact on the normal operation of airport equipment, navigation equipment and airborne equipment.
"Using technical means to strengthen prevention and guidance can avoid some players' mistakes. At the same time, we also appeal to the majority of Feiyou players to comply with relevant laws and regulations and consciously protect the safety of civil aviation clearance." A senior player of drones said.
The first half of the year affected flight 790
Behind Baiyun Airport's launch of the UAV detection and defense system, it is the frequent occurrence of drones entering the airport in recent years.
The "Daily Economic News" reporter found that, including airports in Nanjing, Chongqing, Wuhan, etc., there have been drones that interfere with civil aviation incidents, and the interference of drones has also caused flight downslides or delays.
The Civil Aviation Administration said at a press conference that in recent years, the number of drones affecting civil aviation operations has increased significantly.
According to statistics, in the first half of this year, a total of 44 reports on flight operations affected by drones were received, an increase of 37 from the same period of last year, and 790 flights affected, an increase of 689 compared with the same period last year.
The supervision of drones has become a hot topic in the industry. According to the Southern Metropolis Daily, as of the end of October this year, at least 12 provinces (municipalities and autonomous regions) have publicly released 14 drone-related policies, and some of the remaining 19 provinces have at least 11 prefecture-level cities. The drone related policy was publicly released.
In addition, this year, the civil aviation department released the first batch of 155 civil airport protection scope data, demarcated the UAV airport no-fly zone, and issued the “Regulations on the Registration and Management of the Real-name System for Civil Unmanned Aerial Vehiclesâ€, which is stipulated since June 1 The drone is subject to real-name registration; after August 31, if the owner of the drone does not register and paste the registration mark in accordance with the management regulations, it will be considered illegal.
According to industry insiders, due to the temporary and concealed characteristics of UAV flight, the above regulations can only supervise UAVs from the policy, and still face many difficulties in landing and implementation. Qi Qi, a civil aviation expert, pointed out that the registration did not fundamentally solve the problem. “It’s just what the Civil Aviation Administration can do. The drone supervision cannot be controlled by the Civil Aviation Authority alone.â€
Harsh Environment Membrane Switch
here are several elements and environmental conditions that can cause potential problems for Membrane Switch technologies, including:
Outdoor exposure to sunlight and UV rays
Exposure to harsh chemicals and/or solvents
Operator (mechanical) abuse
Dust and debris, often a problem for devices used outdoors
Extreme humidity
Extreme temperatures, both hot and cold
Atmospheric pressure at high altitudes
Moisture ingress
For this reason it is essential that your membrane switch supplier offer creative solutions to these challenges, both through unique switching technologies such as:
Dynapic Piezoelectric keypads and
DuraSwitch PushGate products.
Much of the process in designing membrane switch technologies for harsh environments involves selecting the appropriate materials and components to provide the protection necessary to ensure the integrity of each component within the membrane switch assembly.
The key considerations are choosing durable materials for the graphic overlay and selecting pressure-sensitive adhesives with the ability to withstand potential contaminants and other elements that could impact performance. A special adhesive sealing process can also be used to create an impervious bond that`s unaffected by the harsh conditions that would ordinarily cause device failure.
There are a range of options when it comes to durable materials and components capable of standing up in harsh, abusive, or rugged environments.
