With the widespread application of intelligent equipment, the automation level of power distribution system is increasing. In order to make full use of the equipment capacity and improve the security, reliability and stability of the distribution system, users need to configure a matching power monitoring system for centralized and efficient management.

As the middleware of the monitoring system, the communication gateway can be widely used in the integrated automation system of power plants, substations, centralized control stations, distribution network sub station/master station system, regional power grid dispatching automation, airport, tunnel, highway and other power monitoring and other electromechanical centralized control systems.

01 Communication gateway SC series

SC series wireless communication modules support transparent transmission modes of LoRa, NB-loT, 4G and RS485. LoRa communication gateway uses serial port to transmit and receive data, which reduces the threshold of wireless applications and enables one-to-one or one-to-many communication.

Among them, the SC2 LoRa communication module is widely used, and its characteristics are as follows:

• Wireless transparent transmission

• Long distance

• Low power consumption

• Disconnection self-recovery

• Support multiple frequency bands

• No additional data traffic costs

Technical parameter

Reasonable and effective use of the gateway can obtain information from equipment and other links, provide real-time data to the power monitoring system (improve the practicability and effectiveness of information), and can timely conduct remote development and maintenance, provided that you have appropriate security clearance authority. 

In addition, due to the wide variety of industrial Ethernet protocols, information may need to be converted and conversed between multiple protocols. Some industrial-grade gateways can realize the interactive transmission of information between wired protocols and wireless protocols.
