A local lighting industry plan that has been promulgated and implemented for 4 years, why should the mission be terminated ahead of time? Does this really mean that the government will not support the LED lighting industry... For this reason, the reporter conducted relevant work for the industry. Interview, dispel the paper scrap.
Shenzhen LED industry: planning can not keep up with changes
It is understood that the "Shenzhen LED Industry Development Plan", which was abolished this time, proposes to build Shenzhen into a national and internationally important LED industry R&D and production base. This is the country's first LED industry development plan, and many of the relevant plans formulated by many cities are based on this, industry insiders said.
In the eyes of some LED industry insiders, "The abolition of the plan is not necessarily a bad thing. At that time, the development of China's LED industry was in the ascendant in 2009. The Shenzhen government wanted to seize the industry's opportunities in the emerging industry of LED, and thus developed the "Shenzhen City." LED Industry Development Plan. Due to the lack of long-term vision of the industrial environment and the rapid development of the industry, the policies proposed in the plan may not be implemented at all.
The abolition has been made, Shenzhen LED enterprises are not hindered
The reporter went deep into the LED enterprise in Shenzhen, and many interviews learned that “abolition of planning, reminiscent of the LED industry or being abandoned by the government†seems to catch the wind.
Talking about the abolition of the Shenzhen LED industry development plan, Quan Jinsong, general manager of Shenzhen Zhaochi Energy-saving Lighting Co., Ltd. said: "Our company mainly does export market, and we do not know that this plan has been abolished. This policy is also for our own business. No effect."
Du Jianjun of Shenzhen Overclocking Technology Co., Ltd. believes that: “Shenzhen LED industry started early and developed rapidly. Most of them are small and medium-sized LED enterprises. There is no real LED industry in the industry. The government is disappointing to abolish planning. It is also normal. ."
Although the old orders are abolished, the government’s support has not changed.
At present, whether it is the "Semiconductor Lighting Energy Conservation Industry Plan" jointly issued by the six ministries and commissions at the beginning of the year, or the "Guangdong Province's implementation plan for promoting the use of LED lighting products", we can see that from the national level to the places of Guangdong and Shenzhen. At the government level, there is strong support for the development of the LED industry.
It is understood that leaders at all levels in Shenzhen actively promote the development of the LED industry, adopt the EMC model to increase the application and promotion of LED lighting products, and fully implement energy conservation and emission reduction work. In March of this year, Shenzhen City, in conjunction with the spirit of the 18th National Congress, led by Mayor Xu Qin, organized a symposium of the person in charge of the Shenzhen Industry Association, and listened to the suggestions and opinions of the leaders of various industry associations to undertake some government affairs by the industry associations. . More than 20 social groups and key industry association leaders from the city attended the meeting.
“Related organizations made a special report on Shenzhen LED industry development to Shenzhen Mayor Xu Qin and Shenzhen Municipal People’s Congress Standing Committee during the day, which led the city leaders to attach great importance to it. The functional units presented a feasibility analysis for each opinion. It can be seen that the government's support attitude and strength to the LED industry has not changed." The relevant people expressed their confidence with great confidence.
Industry upgrade transformation
At present, as the vanguard of reform and opening up, Shenzhen LED industry has taken the first step and developed rapidly. Within two years, more than ten enterprises have landed in the capital market and become an important base for national semiconductor lighting. However, the entire LED industry is very impetuous and obviously overheated. Due to operating costs and competitive pressures, individual companies have broken the capital chain and closed down frequently.
Both the government and industry have begun to examine the judgment and understanding of LED, a strategic emerging industry. Industry analysts pointed out that the abolition of planning may be the wind vane of Shenzhen's LED industry development, re-top design, layout, and promotion of industrial upgrading and transformation.
Quan Jinsong, general manager of Zhaochi Energy-saving Lighting, believes: "The government still needs to support the development of the LED industry, provide a fair competitive environment for the development of the LED industry, and change the disorderly competition of the industry's miscellaneous and bad money. In addition, there is no standard. Enterprises lack the right to speak in international competition.†He suggested that “the government should quickly promote the development of industry standards and win the right to speak for companies to participate in international competition.â€

Analysis of advantages and disadvantages of 4G industrial routers
First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.
For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.
Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.
Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.
Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.
