ZHC4014 is a data transmission device specially used for collecting electricity meters and water meters, and has the function of collecting data and transmitting. One device can collect 30~40 electricity meters/water meters. This product adopts guide rail installation, which can be more conveniently installed in the distribution box. The product is small in size and does not occupy a large area.
This product supports active collection function and can actively collect and report data from electricity meters/water meters. Supports multiple network protocols to meet different user needs. It also supports docking with mainstream configuration software on the market. The product is 4G full network, and the price is as low as ￥219 yuan/unit.
Product Features
1) Host and slave modes: The host mode supports RS485 cascading of multiple devices, and the data collected at the same time can be sent to multiple servers at the same time. If the main server goes down, the backup server can send and receive data normally to ensure that data is not lost.
2) Supports multiple network protocols: supports TCP_Client, DUP, HTTP_Client, Modbus RTU/TCP. Can meet the different needs of users.
3) Data transparent transmission: ZHC4014 is a two-way transparent transmission. What the DTU sends is what the server receives. What the server sends an instruction is what the DTU receives. Users do not need to care about complex transmission protocols. Quick networking and quick application.
4) Cloud forwarding and cloud networking: Through cloud forwarding, data can be sent to another device through Zongheng Cloud to achieve one-to-one networking. Cloud networking can be implemented based on Zongheng Cloud with low cost. At the same time, users can also network with their own servers.
5) Other functions: Support setting APN, SIM card number query, local/remote results, virtual serial port remote operation.

Applications
Remote power meter reading application cases
In a certain industrial park, it is necessary to count and record the power consumption of the factory in order to facilitate charging. This solution uses the rail-type 4G DTU (ZHC4014) developed by Zongheng Intelligent Control. The ZHC4014 is placed in the electric meter box of the distribution terminal, collects data from several electric meters in the factory, dormitories, and office buildings, and transmits the power parameters of the electric meters to the real-time Management platform to complete monitoring and analysis of energy consumption data. By transmitting the data to the management platform, managers can see the electricity consumption data of each area in the factory in real time, and based on this data, charge the corresponding electricity fees to the factory.
