Intelligent single-phase electrical energy metering tank

Abstract

The invention discloses an intelligent single-phase electrical energy metering tank, which comprises a microprocessor as well as a drain current detection module, an ammeter box total electricity metering module, a wire inlet side temperature collection module, a single-phase meter reading module, a display prompting module, a box opening incident recording module, an information storage module, a watchdog module, a wired communication interface, a wireless communication interface, a centralized reading system interface and a power supply module, which are respectively connected with the microprocessor, wherein the single-phase meter reading module is respectively connected with three single-phase meters, a PC (Personal Computer) reading system is connected with the wired communication interface, and a wireless PDA (Personal Digital Assistant) is connected with the wireless communication interface. The metering tank can prevent the ammeter box from being illegally opened and prevent electric larceny, has multiple communication functions, is compatible with a centralized meter reading system, sound in functions, and can meet the use requirements; the whole system is an opened system; and when the temperature exceeds a set value, the metering tank can alarm in time, thereby being safe and reliable in use.

Description

technical field [0001] The invention relates to an intelligent single-phase electric energy metering box. Background technique [0002] Stealing electricity has always been a major problem for power supply enterprises. Stealing electricity not only causes serious economic losses to the country and the collective, but also restricts the improvement of economic benefits. With the rapid development of science and technology, the way and technology of stealing electricity are getting more and more sophisticated, and it is difficult for the traditional anti-stealing methods to achieve the desired effect. [0003] The usual means of stealing electricity is to illegally open the metering box and then illegally adjust the meter. Traditional meter boxes generally use mechanical built-in locks, which can be easily opened by electricity thieves. The basic types of power theft can be roughly divided into: [0004] 1. Electricity stealing by undervoltage method [0005] Electricity t...
