Description

Electrical data acquisition system based on measuring switch Technical Field The utility model relates to the technical field of electric energy data acquisition, in particular to an electric data acquisition system based on a measuring switch. Background In the current field of electrical data acquisition, conventional acquisition systems face a number of serious problems. With the continuous development of power systems and the increasing demand of users for fine management of power data, higher requirements are put on the accuracy, real-time performance, safety and comprehensiveness of electric data acquisition. The previous collection mode often depends on simpler ammeter measurement and basic communication means. The ammeter has single function, only can provide limited electric energy metering data, can not meet the comprehensive and accurate measurement requirements on various parameters such as voltage, current, power factor and the like, and is difficult to realize comprehensive monitoring and analysis on the running state of the electric power system. In the aspect of communication, a low-speed and unstable transmission mode is mostly adopted, such as the traditional serial port communication, the data transmission rate is low and is easy to be interfered, so that the data transmission delay is high, the packet loss rate is high, and the quick and reliable data uploading and remote monitoring cannot be realized. Moreover, there are serious disadvantages in terms of data security. The electric power data relates to user privacy and electric network operation safety, but the traditional acquisition system lacks an effective encryption and safe storage mechanism, so that user electricity information and electric network key parameters are easily stolen and tampered illegally, and the stable operation and user benefits of the electric power system are seriously threatened. In addition, the monitoring and protection capability for circuit faults is limited. When the circuit is in face of common circuit faults such as overload and short circuit, early warning and quick circuit cutting-off cannot be effectively carried out in time, safety accidents such as electric fire and the like are easy to cause, and huge losses are caused to life, property and electric facilities of users. In summary, it is urgent to develop a novel electrical data acquisition system with multiple functions, high reliability, strong security and high-efficiency communication capability, so as to adapt to the development requirements of the modern power industry and ensure the safe and stable operation of the power system and the electricity safety of users.
