Working Mode of RTU IOT Cellular Modem

1.HTTP Client
Support serial data transmission to designated server via HTTP.
2. TCP Client
The serial server actively initiates a TCP connection to the server. If it fails, it will continue to reconnect until it succeeds. If the connection is successful, the server and the serial device can perform two-way transparent data transmission.

 

  • Data collection
  • of
  • 4G IOT Cellular Modem
  •  
  •  
  •  
  • It mainly completes the real-time collection and reporting of energy data. All kinds of important status data required for enterprise energy management must be completed by reliable data collection terminals. Data collection is mainly composed of the central receiving server and the lower-level collection terminal. The data acquisition terminal is connected to the metering instrument through RS232/485 to obtain real-time data, and then the real-time data is sent to the central data receiving server through the 4G network.
