RS485 MODBUS RTU IOT Cellular Modem With Digital Input Output Ports

• 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.

• Intelligent agricultural irrigation

• 
  The field all-in-one fertilizer and water machine is connected to RTU, which 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.If the machine fails, the alarm will be sent to the management personnel's mobile phone through RTU to achieve rapid early warning processing and reduce the failure.Irrigation and fertilization equipment combined with irrigation and fertilization system, through the data analysis of various sensors, scientific and reasonable arrangement of irrigation and fertilization plan, timing and quantitative, time temperature control, accurate proportion, combined with the most advanced irrigation control system, to achieve the precise control of irrigation amount, fertilizer amount and water and fertilizer application time.

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.
