Embodiment Construction
[0016] Such as figure 1 As shown, the intelligent metering monitoring system of the present invention comprises a current acquisition unit 1; a voltage acquisition unit 2; an A / D conversion unit 3; a processing unit 4; a display unit 5; an input unit 6; device 8. The current acquisition unit 1 and the voltage transformer 2 input the collected analog current signal and voltage signal to the A / D conversion unit 3, the A / D conversion unit 3 is an analog-to-digital conversion unit, and the A / D conversion unit 3 inputs the input analog The current and voltage signals are converted into digital current and voltage signals and input to the processing unit 4. The processing unit 4 records and stores the current value and the current change curve and the time when the voltage signal is abnormal after the metering system fails, and then the GSM short message module at the user end Carry out SMS alarm to the host monitor 8 in the form of mobile phone text messages, and send the user num...

The invention relates to an intelligent metering and monitoring system which can monitor a voltage signal of a secondary side of a voltage transformer and an electric current signal of a secondary side of a current transformer. When the intelligent metering and monitoring system is used for monitoring, an input unit (6) is used for starting respective corresponding computer programs, and then a single-chip microcomputer controls the acquisition of the voltage signal and the electric current signal needed by a processing unit (4); when the metering system goes wrong to result in the metering failure and the voltage signal collected by a voltage acquisition unit (4) is abnormal, a user side GSM (Global System for Mobile Communication) short message module gives alarm to a host machine monitor (8) in a short message manner and sends a user number at the failure place, a specific address, information of a nameplate of a metering box and related operating data to the host machine monitor (8) so that a worker is informed to timely overhaul the metering system, thereby the purpose of intelligent and real-time monitoring is realized. The intelligent metering and monitoring system mainly comprises an electric current acquisition unit (1), the voltage acquisition unit (2), an A / D (Analogue to Digital) converting unit (3), the processing unit (4), a display unit (5), an input unit (6), the user side GSM short message module (7) and the main host machine monitor (8). The intelligent metering and monitoring system has simple and compact structure, good reliability and real-time monitoring function.
Description
technical field [0001] The invention mainly relates to the field of power metering systems, in particular to an intelligent metering monitoring system. Background technique [0002] The high-voltage metering device is an electric energy metering device for trade settlement between power supply companies and large-scale electricity customers. Power marketers rely on reliable energy metering data to achieve a balance between power supply, power purchase, and electricity sales to ensure the safe, reliable, and economical operation of power companies. Therefore, power supply departments not only need to improve the quality of power supply, but also accurately measure the electricity sold. The metering of electric energy, especially the correct metering of the high-voltage power metering system, is particularly important today when the electricity consumption is increasing. [0003] The high-voltage metering device is generally composed of high-voltage voltage transformers, curr...
