Introduction to rs232 to 4G equipment
ZHC4012, developed and produced by Zongheng Intelligent Control, referred to as 4G DTU, provides one RS232 and one RS485 interface, and the network is 4G full Netcom. RS232 serial port data can be converted to 4G and sent to the server or another device. The device supports active collection and reporting, which can reduce server pressure. Anti-static and anti-surge. The product is industrial grade.
This device is widely used in:
Hydrology and water conservancy – reservoir monitoring, flash flood monitoring, water plant automation, etc.;
Electric power industry – remote meter reading, smart power supervision, wind energy engine monitoring;
Environmental monitoring – dust monitoring, urban air monitoring, forest fire control, etc.;
Product features one
Supports one-to-one networking and one-to-many networking. One-to-one networking is suitable for small projects and is characterized by low cost and no need to rent a server. You can use your own computer at home as a monitoring platform. For example, you want to monitor a pool in a mountainous area. When the water level falls below a certain value, an alarm message will be sent to the computer at home. When the alarm is issued, it means that the water inlet of the pool is blocked, and you can go to deal with it as soon as possible. Avoid interruption of water supply to villagers.
Specific implementation: Use one ZHC4012 as the transmitter, connect it to a water level sensor, place the device in the pool, and use another ZHC4012 device as the receiver, connect it to the computer at home. Then use Zongheng’s free transparent cloud to implement a simple pool remote monitoring system.
Product features two
Support active collection to reduce server pressure. The traditional DTU process issues collection instructions to the server, and then the DTU receives the instructions and issues data acquisition instructions to the sensor. After obtaining the sensor data, the DTU uploads it to the server.
As for Zongheng Intelligent Control’s DTU (ZHC4012), the DTU itself has an active collection function. You only need to set the corresponding collection time in the configuration software, and the DTU can regularly obtain data from the sensor and upload it to the server.
