- 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.

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.
