With the rapid development of China's national economy, China's energy consumption has also grown rapidly. Recently, domestic cities such as “smog†and global warming have shown that China’s environmental carrying capacity has reached its limit. This means that China must save energy and promote economic and social development in harmony with the population, resources and environment. The semiconductor lighting ( LED ) industry, as a model of low energy consumption and low emissions, has become a strategic emerging industry in the national energy conservation and emission reduction targets and has received much attention. To this end, the Chinese Academy of Sciences established the “璀璨 Action†project. Since the establishment of the project, we have been committed to serving the LED industry and social development.
Accelerate life testing standards and regulate the market
With its tens of thousands of lighting products manufacturers, China has become the world's largest lighting product production base, and will soon become the world's largest lighting products consumer market. However, the LED industry standard system has not been perfected, and the relevant standards are missing, resulting in a mixed quality of products, and a chaotic market situation of good and bad products. Caused consumers to lose confidence in LED lighting products .
So, is the led lighting industry really an energy-saving industry? In fact, among the parameters affecting the reliability of led lamps , life is the most representative parameter. If the life is short, it is an industry that consumes energy. As the people joked, "This is a lamp that saves electricity and does not save money."
To this end, “璀璨Action†established the concept of energy-saving life, shortening the life inspection time of LED products from 6000 hours to 1000 hours, and has completed the energy-saving life calculation of more than 20 kinds of lamps of 4 types of light sources. For the LED products to seize the market to win the first opportunity, reduce product development costs and maintenance costs, bring greater economic benefits to the enterprise.
Joint cooperation and sharing
The LED lighting product rapid testing team gathered 7 research institutes including the Changchun Institute of Optics, the Beijing Institute of Semiconductors, the Beijing Institute of Electrical Engineering, the Beijing Institute of Chemical Technology, the Shanghai Institute of Technology, Ningbo Materials, and the Chinese Academy of Metrology. The intellectual property rights of all scientific research results, the LED reliability database of big data, and the benefits generated by accelerating equipment applied to quality inspection organizations are all shared. Among them, the big data LED reliability database is based on cloud network, which is open to the public and dynamically updated. “Operational Action†seeks to serve the industry and serve the health of the people.
At present, the research team is in contact with some large domestic LED manufacturers , such as Huizhou NVC Optoelectronics Technology Co., Ltd., which is purchasing its BPZ800-830 E27 9W led bulb lamp to complete accelerated life testing and service for some enterprise LED lighting products. Work can not only facilitate the accelerated testing of manufacturers, but also save costs. It also builds data for the open, big data LED reliability database for the project.

Domestic communication, 4 g module in addition to support two kinds of LTE FDD LTE/TD - LTE standard, also compatible with 2 g / 3 g down, support td-scdma/WCDMA/EDGE/GP/GSM/CDMA1X/EVDO mode. The data service downstream rate can reach up to 100Mbps, the uplink rate can reach up to 50Mbps, providing customers with high-speed Internet access and wireless data connection and other functions. In addition to providing high-speed data access, it also provides voice, SMS, communication book and other functions, which can be widely used in notebook, tablet, touch screen communication devices, smart phones, video surveillance, multimedia mobile phones and vehicle equipment and other terminal products and vertical applications. Today, I will introduce you to what is 4G module and how to use 4G module.
What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Through high-speed networking, the 4G module transmits all terminal business data and equipment operating status to the business center in real time. Through the management monitoring platform, the terminal equipment operating status can be monitored in real time and equipment faults can be timely checked. The efficiency has been greatly improved in many aspects such as operating cost, operation scale and service timeliness. Suitable for shared massage chair, public charging pile, vending machine, vehicle system, environmental monitoring, power remote monitoring and other industries.
