Industrial Wireless Transmission System Based on Industrial 4G DTU Power Distribution Network

The traditional distribution network operation management relies on a large amount of manpower, which is time-consuming and labor-intensive, has low work efficiency, and lacks real-time. In order to solve this problem, it is necessary to adopt modern sensor measurement technology, communication technology, computer information technology and automatic control technology. By using advanced sensors, meters, digital controls and comprehensive analysis software to realize automatic monitoring of power grid, optimization Power grid performance, power outage, fast recovery and other functions.

Distribution system automation is the use of modern electronics, computers, communications and network technology to integrate distribution network online data and offline data, distribution network and user data, grid structure and geographic graphics to form a complete automation system, DTU due to the use of economical and efficient structure, which becomes the most effective communication method for connecting the monitoring unit in the ring network cabinet of the city distribution network, makes the distribution automation system more advanced and more efficient.


Program Description:


1. The power secondary device establishes serial communication with the DTU through the serial communication interface.
2. The DTU transmits the core data such as the secondary device status information to the power station main station through the GPRS network and the power private network.
3. The communication terminal needs to have the protocol conversion function of the power 101 protocol and the power 104 protocol.

System value:

Power users put forward higher requirements for power quality and power supply reliability. The traditional urban distribution network structure and protection, operation and management methods have not adapted to the needs of the development of the power market, and a new power distribution mode is urgently needed to resolve this contradiction. By adopting the 4G DTU/GPRS distribution network automation solution, the power outage time is reduced, and the service level of the power supply enterprise is improved.

What is CPE?

#5G #CPE #Router #Industrialrouter #CAIMORE Its full name is Customer Premise Equipment. It can convert the signal provided by the operator or the wired broadband signal into a broadband or Wi-Fi signal that we can use directly. 5G CPE is a 5G terminal device that receives the 5G signal sent by the operator's base station, and then converts it into a Wi-Fi signal or wired signal, allowing more local devices (mobile phones, tablets, computers) to access the Internet. The function of 5G CPE is similar to that of a home router, but because it has a built-in complete communication module, it supports providing Wi-Fi signals to terminal devices by consuming "traffic" through the SIM card. By comparing the following tables, we can clearly see the difference between 5G CPE and home routers: Device 5G CPE Home Router Plug and play YES NOT How to use SIM card + network cable network cable Signal Source Base Station + Mobile Data Chip Cable cable, modem S ignal coverage Wide G ener

#kiosk #industrialautomation #wirelesscommunications #ipc  #CAIMORE #IIOT #M2M #industry4 No access control card, no keys, no fingerprints, you can pass through the gates of office buildings, residential areas, factories, campuses, etc   through face recognition . Due to its safety, convenience, and intelligence, face recognition has gradually become the mainstream of security access management and is widely used in various industries, such as face payment, face unlock, face punching and so on. Face recognition is a biometric technology that quickly completes identity recognition based on human facial features. When the user enters the range of the camera through the face recognition system, the system will quickly capture the face for identification, analysis and comparison, and judge identity. So, how is the industrial compute r applied in the face recognition system? The composition of the face recognition system, taking the face recognition gate system as an example, is mainly comp
