Remote monitoring system of PLC equipment based on edge computing gateway
I. Background
PLC, as the main technical means of information collection and control, is bound to play a key role in the construction of the Internet of Things, which is the opportunity for the PLC industry. However, although the traditional PLC can access the Internet of Things, the implementation steps are complicated and the cost is high. The information exchange and communication of the Internet of Things is also complex engineering, and often PLC implementors do not have this knowledge.
The application of PLC in the industrial control industry has been very common, the stability and practicality of PLC has been welcomed by everyone, with the rapid increase of PLC field application, the remote centralized management of PLC has become the biggest bottleneck.
Therefore, the promotion and application of PLC is also a huge difficulty. Ailutong launched PLC equipment remote monitoring system to provide efficient and stable data transmission, timely and accurate data monitoring and analysis, to help you enter the cloud era of industrial Internet.
Ii. System overview
Alutong edge computing gateway is connected with the on-site PLC or touch screen, and the data is transmitted to the data center through 4G/5G or wifi. Alutong Cloud platform can display the on-site data in real-time image through the configuration, and users can remotely monitor and maintain it through the large screen, PC or mobile phone.
Third, system composition
The traditional PLC communication mode generally uses 485, Ethernet communication, but many places in the industrial control site can not have the adjustment of wiring, and the wiring cost is high and vulnerable to bad weather, to GPRS/3G/4G to replace the existing communication mode, fundamentally solve such problems.
* Front end: PLC is connected to wireless communication equipment through 485 or network cable, so as to achieve the purpose of connecting with the Internet.
* Communication: The wireless device is connected to the PLC monitoring and management center in the Internet through the operator network.
* Background: The existing PLC monitoring platform does not need to be changed and upgraded, and directly communicates with the on-site PLC through the virtual serial port or the network to achieve the unified monitoring and management effect of PLC.
Fourth, system characteristics
1, Ailutong PLC equipment remote monitoring system with edge computing capabilities, to achieve real-time data processing, local pre-analysis, real-time fault warning. At the same time, through the collaboration of edge computing and cloud big data analysis, predictive operation and maintenance is achieved.
2, the system supports PLC program remote update and download, with PLC remote debugging function.
3, the edge computing gateway in the system can be connected to the camera, support video analysis, etc., and open to third-party software developers through the industrial gateway, to facilitate PLC users to develop unique value-added functions.
4, the edge computing gateway interface is rich, including a variety of Alutong protocols, support Modbus, Mitsubishi, Siemens, Omron and other protocols; It can connect well-known PLC and HMI equipment at home and abroad.
5, the system can achieve big data management and data analysis, intelligent analysis display industry curves, reports, map location, etc. Support Web and mobile phone APP call and display.
