Product Description

RS485 To GPRS IOT Cellular Modem GSM M2M Gateway For Data Transmission

 

  • Introduction​ of IOT Cellular Modem

 

ZHC2921 is a network IO product that supports 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) output, 4-channel analog (current 4~20mA) detection, and 1-way serial port passthrough transmission. It is compatible with Modbus RTU/TCP protocol.With the function of "remote control" as the core, it is highly easy to use, and users can easily and quickly integrate into their own system to realize the remote control based on GPRS network.

  • Solution of IOT Cellular Modem
  • Intelligent agricultural irrigation

  •  

  • RTU ZHC2921 collects the data of the controller and sensor via Modbus TCP, preprocesses the local storage and uploads the data via 2G.The cloud platform monitors the information of the fertilizer and water integrated machine in real time, and realizes the remote automatic control of the computer and mobile phone.

  •  

  •  

    System function

     

    Support centralized equipment management, remote maintenance, program update

    Support historical data query, historical data export

    System authority management, support hierarchical authority working mode

    Support fault alarm, mobile APP/PC remote control

     

  • System advantage

  •  

     

    Water saving and fertilizer saving -- greatly improve water and fertilizer utilization rate, water saving and fertilizer saving 50%-70%;

    Intelligent control -- automatic feedback control of irrigation according to soil moisture and other relevant parameters;

    Time and labor saving -- real-time online remote monitoring, rapid large-scale irrigation and fertilization;

    Increase production - The system can increase production by 30-50%.
