Model: ZHC491G is a 4g full network DTU developed by Chengdu Zongheng Intelligent Control. It has 7 modes and 16 frequencies , which can meet the frequency bands of domestic and foreign operators. It supports multiple network protocols, TPC protocol, UDP protocol, HTTP protocol, and supports Actively collecting sensor data and instrument data can eliminate the need for a controller and save costs for users. It is also simple to use and easier to get started! (GPS positioning function is currently supported, and the accuracy can reach within 10 meters)
4g full network dtu application
1. 4G full network DTU can be used for smart meter collection and remote meter reading. It can directly collect data on the electricity meter or water meter and actively upload it to the customer’s server.
2. Smart charging piles. The application of 4G full network DTU in smart charging piles can send the data from the detection of charging piles to the server and cloud platform in real time.
4g full network DTU can not only be used in the above cases, but also can be used in flash flood/flood discharge monitoring, construction site dust monitoring system, automatic payment inquiry terminal, bus wireless network, industrial control field, traffic management, environmental monitoring, meteorology, Water conservancy, coal mines, etc.
Why choose 4g full network dtu?
1. The signal is better. The traditional GPRS network will have no signal or weak signal in remote mountainous areas, while the 4G network has better signals than GPRS in most places.
2. Handle network abnormalities, such as single-mode and single-frequency DTU. If the local network is abnormal and there is no network, the data transmission of the gprs module will be directly interrupted. For 4G full network DTU , if the local network is not good, it will automatically switch to other devices. Network frequency band, continue to provide users with data transmission!
Advantages of Zongheng 4G full network DTU
1. Supports multiple network protocols, including tcp, udp, and http protocols (two-way transparent transmission). 2. Actively collect instrument and sensor data to save costs and make transmission more convenient.
3. Supports WEB remote configuration, applet configuration, and FOTA firmware upgrade, which is simple and convenient.
4. Data can be sent to multiple devices in real time at the same time and the data can be viewed at the same time.
5. Supports GPS positioning function with accuracy within 10 meters.
