• Introduction​ of 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 IOT Cellular Modem

Working Mode of 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.

• Application
• of
• IOT Cellular Modem
•  
•  
• ZHC4941 can be used in water quality online monitoring system. It sends water quality monitoring information and data to the monitoring center through GPRS/4G/LORA and other communication networks, which can realize automatic online sampling of water quality and real-time grasp of water quality; water quality parameters are automatically collected by monitoring points With remote communication and transmission, the computer control center of the central station conducts data collection, sorting and comprehensive analysis; monitoring information can be transmitted to relevant water conservancy and water management departments to provide an effective basis for supervision and management of water quality. Applicable to: water source monitoring, online river water quality monitoring, environmental monitoring stations, municipal water treatment process, municipal pipeline network water quality supervision, rural tap water monitoring; circulating cooling water, swimming pool water operation management, industrial water recycling, industrial aquaculture, etc.
