RS485 to 4G

Traditional serial port equipment (such as RS485/RS232) has been widely used in daily production of enterprises. However, in the typical industrial automation field, long-distance monitoring often needs to be achieved from hundreds of meters to several kilometers. If you want to achieve wireless control signals on industrial sites, you will face such problems: the distance is too far, the data is too scattered, and other problems Due to wiring restrictions, information transmission and networking often suffer from problems such as line damage and difficult wiring.

RS485 to 4G IoT gateway is specially used to convert serial port data into 4G wireless network access to the Internet, such as electricity meters, water meters, various instruments and meters, and inverters, UPS, mechanical equipment, generators, battery testers, air conditioning controllers, etc. The data from serial devices such as charging piles is converted to access the Internet through the wireless 4G network, thereby enabling remote monitoring of the equipment. It is widely used in industrial Internet of Things fields such as intelligent manufacturing, industrial automation, sewage detection, smart transportation, and smart grids.

Zongheng Intelligent Control’s RS485 to 4G IoT gateway adopts an industrial-grade design and can be directly embedded in temperature and humidity sensors, flow meters, air compressors, vending machines and other equipment, and can be quickly and reliably connected to the cloud platform to achieve real-time data Transmit and view, and realize functions such as parameter setting, remote operation and control on the cloud platform.

RS485 to 4G IoT gateway working method:

TCP Client communication. The serial port 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 port device can perform two-way transparent data transmission.

HTTP Client communication. Supports HTTP transmission of serial port data to the designated server.

The RS485 to 4G IoT gateway uses the operator’s TD-LTE or FDD-LTE 4G network to realize bidirectional data transmission between the device embedded in the module and the remote server when there is no network outdoors. It has fast communication speed and good compatibility. Features.

Zongheng Intelligent Control’s RS485 to 4G IoT gateway provides supporting free cloud platform services, and the device can realize one-to-one, one-to-many, and many-to-many applications. Virtual/physical serial ports, etc. can be used to achieve remote/local and other configuration methods. The equipment can be connected to various commonly used configuration software and realize data collection and control of PLC.
