• Introduction​ of RTU IOT Cellular Modem
• 4G IOT Cellular Modem ZHC4941 is an industrial-grade 4G RTU that provides 8 DI, 8 DO, 8 AI and 1 RS485/232 interface, supports local logic processing operations, automatic acquisition and active reporting, Modbus RTU/TCP adaptation, and automatic threshold calibration Special functions such as reporting, configuration software docking, dry and wet node IO detection, support one-to-one, many-to-one network.

Parameters of RTU IOT Cellular Modem

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.

Founded in 2015, Chengdu Zongheng Intelligence Control Technology Co., Ltd. is a high-tech enterprise focusing on the research, development, production and sales of Internet of Things communication control terminal products and related overall solutions. Takes the IOT intelligent communication terminal as the entry point, combines edge computing and big data cloud platform, and realizes data collection, transmission and intelligent control and other functions in the application of the Internet of Things. At present, the company's products have been widely used in intelligent water conservancy, intelligent agriculture, intelligent audio-visual and other scenes.
