With the rapid increase in social electricity consumption and the complexity and diversity of electrical equipment, the supervision of safe electricity consumption has become an important part of social safety management. Safe electricity supervision refers to the real-time monitoring of the whole process of electricity operation, timely discovery of potential safety hazards in the line, accurate and rapid positioning and solution, so as to ensure the safety of the line and reduce the occurrence of accidents.
A very important part of the process of safe electricity supervision is to collect the operation data of the terminal line, and the terminal equipment of the installation of the first road is responsible for collecting the data, and the data must be collected and analyzed through a certain communication method, so as to carry out centralized supervision of the operation of the power line.
There are several commonly used communication methods for safe electricity supervision:
1. RS485 communication: 485 communication refers to the wired communication mode, that is, the terminal data acquisition equipment is connected with the monitoring host through the connection line, and the data is transmitted through the wire. This communication method is mainly used in traditional places with fire control rooms, and the wires have been laid out during the construction of the building. The disadvantage of this communication method is that the communication distance is relatively limited.
2. LoRa communication: This communication mode belongs to local area communication, that is, it can only be transmitted in a certain range of space, and it needs to have a transceiver device at the same time, that is, a transmitter device is installed in the terminal acquisition equipment, and a receiving device is also required, such as a base station. LoRa communication is mainly used in places in the area that cannot be connected to external networks, such as prisons, where normal communication networks are blocked, and terminal data is collected by establishing a special local area network. The base station is built where there is an external network, and then other wireless networks are used to upload the data collected in the base station to the cloud for management.
3. NB communication: This communication mode has a relatively narrow bandwidth, that is, it can transmit less content, and is not suitable for the environment that requires frequent and large data transmission, but is suitable for the equipment environment with a small amount of data, such as wireless gas fire extinguishing device. This kind of equipment does not need to upload data frequently and regularly, but will upload alarm data when there is a potential safety hazard, so it is economical to use NB communication without affecting normal use.
G communication: This communication method is more familiar to us, contrary to NB communication, it is suitable for a large number of data transmission equipment, such as safety electricity detectors, which need to be updated and uploaded in real time. The disadvantage of using 4G communication is that the cost is relatively high.
Different places and different communication equipment can choose different communication methods according to their needs, and Heyue Intelligent can customize targeted solutions according to the actual needs of customers and the environment of the place, which not only solves the needs of safe electricity supervision, but also saves manpower and financial resources.
