Release time:2020-01-15 13:50:40

In the power industry, the Internet of Things technology has been widely used, especially wireless communication technologies such as LoRa, NB-IoT, 3G / 4G, etc. are particularly important in the field of power meter reading, which is also an inevitable trend of the development of the IoT electrification. 
Monitoring of large-scale factory pollution control equipment that is not easy to wiring
Power monitoring of oil field bunkers that are not easy to wire

Power monitoring of large machinery in smelting enterprises that is not easy to wire

Deploy relatively independent remote areas, such as operator base station power monitoring
The wireless smart meter system is mainly composed of wireless smart meters, wireless smart gateways, wireless LoRa / NB-IoT / 2G / 3G / 4G networks, servers, screen walls, and mobile devices. In areas where meter deployment is more concentrated, the meter collects data and transmits the data to the smart gateway through LoRa, and then the smart gateway sends the data to the monitoring center server through a wired or wireless cellular network. Where the meter deployment is relatively independent, the meter collection The data is selected according to the local network and traffic cost. The appropriate NB-IoT / 2G / 3G / 4G network is directly transmitted to the monitoring center server, and the final meter data is displayed on the curtain wall of the monitoring center or on the mobile terminal APP.

Meter access gateway adopts LoRa transmission technology, long distance, stable transmission, and many access points;
The system uses LoRa / NB-IoT / 2G / 3G / 4G and other wireless communication technologies to meet the needs of different scenarios of centralized deployment and independent deployment of electricity meters;
The system mostly uses wireless communication methods to minimize the wiring work, reducing wiring costs and subsequent maintenance costs;
The system uses wireless communication, and it is easier to add and delete meter nodes in the later system.
