The improvement of product quality is inseparable from the standard. But when the standard one fashion can't meet the actual needs, what should we do? The Guangdong Provincial Standardization Institute gives an effective answer with innovative examples. This is to use the principle of benchmarking to establish a benchmark product index, which is a comprehensive product quality evaluation system, to promote product upgrades and standardize industry development. This innovation in the field of standardization has undoubtedly opened up new ideas for quality work. At present, the development of emerging industries and emerging technologies is changing with each passing day, and the contradiction of technical standards is becoming more and more prominent. Under such circumstances, how to promote the healthy development of new technology products through the innovation of working mode is a big problem that needs to be solved by quality inspection workers. Guangdong's “Benchmarking Method†for LED lighting products has set a benchmark for us to solve problems.
The Guangdong Provincial Institute of Standardization closely follows the pace of emerging industries. With the support of the Provincial Science and Technology Department and the LED Lighting Industry, Education and Research Innovation Industry Alliance, the LED lighting product benchmark index has not only realized the dynamic evaluation of the quality of LED street lamps, but also solved them. Industry standards lag behind the contradiction of technological development. According to Xiong Yong, dean of the Guangdong Institute of Standardization, the move will promote the upgrading of technology and standards for the entire LED lighting industry. It will also provide innovative exploration for the research and technical standards of emerging industry technology standards.
The LED lighting industry has become one of the most important emerging strategic industries in Guangdong. Last year, the province's LED lighting industry grew by more than 25%, with more than 2,600 companies and 1.3 million employees. The industry scale has ranked first in the country. However, due to the high-speed updating of LED lighting products technology, on the one hand, the cycle of product standard setting cannot keep up with the speed of technological development, and the phenomenon of lack of standards and lags is formed. While restricting the rapid spread of technological innovation results, it also causes the dilemma of product quality supervision; On the other hand, there are many steps in the development and revision of standards. From the drafting to the release, the implementation period is long. Some indicators even face the situation that the standards are outdated, which makes the users lack the scientific evaluation of the quality of LED street lamps. The market competition is disorderly and the product quality is uneven. , seriously restricting the healthy development of the LED industry.
To this end, the Guangdong Provincial Institute of Standardization, through cooperation with the LED Lighting Industry Alliance, organized and implemented the “Guangdong Province Green Lighting Demonstration City Product Benchmarking Index Research and Implementation†major research project. The core of the project is in the field of LED lighting industry. In view of the insufficient development of LED lighting emerging industry technology and rapid technological advancement, the product indicators with “significant relationship†with the quality of LED lighting products are selected, and the products are measured relative to the benchmark index. Quality, thus establishing an innovative dynamic LED lighting product quality evaluation system, combined with third-party testing and unified platform evaluation, quality, energy efficiency evaluation and positioning of LED lighting products on the market (first from LED street lights) Classification, its testing methods and standards will be dynamically updated according to the latest published standards and technical methods at home and abroad.
It is reported that the application of the benchmark index in the quality inspection of LED lighting products is conducive to abandon the dispute and solve the common problems encountered in the current LED lighting product quality supervision, testing technology development and platform integration, breaking through the current development of LED lighting industry. The standards are imperfect, and the detection methods cannot keep up with bottlenecks such as technological development. At the same time, the establishment of dynamically updated product benchmarking index and product standard testing and certification system, which has made breakthroughs in public technology aspects such as standards, certification and testing of LED lighting products, and provided scientific quality assessment system for LED lighting products in green lighting demonstration cities. .
The benchmarking method was first created by Xerox in the late 1970s, and then systematically and standardized by the American Productivity and Quality Center. The basic idea is to extract the "comparability" index from multiple research objects and compare them to determine A scientific evaluation is given to the position of a research object in its population. According to statistics, nearly 90% of the world's top 500 companies have applied benchmarking. The LED lighting product benchmark index promoted by Guangdong is based on the benchmark analysis principle, injecting new content in an innovative way according to the actual development of the industry, testing the LED benchmark products representing the industry's innovative technology level, and calculating the product quality comprehensive evaluation system after calculating the index. The benchmark index of LED lighting products researched by the institute is dynamic and continuous with the development of technology. It is conducive to maintaining the synchronization between standards and R&D technology. It can not only locate the current stage of industrial technology development, but also coordinate disputes. Forming alliance technical standards, and even industry and national standards provide a scientific basis.
Xiong Yong believes that in order to adapt to the development of strategic emerging industries, the benchmarking index research is an innovative exploration of standardization work under current conditions. Through the benchmarking index and benchmarking method, the application of the system in the LED lighting industry will explore new paths and create new experiences for common problems that may be encountered in the fields of technical standards construction, quality assessment, testing and certification of strategic emerging industries.

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.
