Abstract
The utility model discloses a multi-user electric energy meter, comprising a microprocessor and a plurality of metering chips; the metering chips are all in connection with the microprocessor and are all doublecurrent sampling metering chips. The multi-user electric energy meter can perform sampling on live wires or zero lines, as a result, electricity stealing can be judged through the difference between the live wires or zero lines; accordingly, electricity security of users can be guaranteed and great loss for the state caused by electricity stealing can be prevented.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of multiuser electric energy meter.
Background technology
The multiuser electric energy meter of prior art comprises a microprocessor and a plurality of single current sample computation chip, and described a plurality of single current sample computation chips all are connected with microprocessor.There is following defective in the multiuser electric energy meter of said structure in the use of reality: because existing multiuser electric energy meter adopts single current sample computation chip to sample and measure; It can only only be sampled to live wire or zero line; Therefore when electricity filching behavior takes place; Only can't judge at all through multiuser electric energy meter whether electricity filching behavior takes place, so not only can make user's electrical safety be affected, and electricity filching behavior can bring great loss to country.
The utility model content
The technical matters that the utility model will solve is, overcomes the defective of above prior art, and a kind of multiuser electric energy meter that can prevent that electricity filching behavior from taking place is provided.
The technical scheme of the utility model is, a kind of multiuser electric energy meter is provided, and comprises a microprocessor and a plurality of computation chip, and described a plurality of computation chips all are connected with microprocessor, and described a plurality of computation chips are double-current sampling computation chip.
The model of said double-current sampling computation chip is BL6501A.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model multiuser electric energy meter employing double-current sampling computation chip is sampled and is measured; It is all sampled to live wire or neutral line current; Therefore when electricity filching behavior takes place; Its difference through live wire electric current and neutral line current can judge whether electricity filching behavior takes place, and so not only makes user's electrical safety be guaranteed, and has prevented the very big loss that electricity filching behavior brings to country.
As improvement; Described multiuser electric energy meter also comprises a remote communication module; Described remote communication module is connected with microprocessor, can electricity consumption data and stealing alerting signal be transferred to control center through this remote communication module, thereby effectively the problems referred to above handled.
Description of drawings
Accompanying drawing is the circuit structure block diagram of the utility model multiuser electric energy meter.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in accompanying drawing; A kind of multiuser electric energy meter of the utility model comprises a microprocessor and a plurality of computation chip, and described a plurality of computation chips all are connected with microprocessor; Wherein multiuser electric energy meter also comprises some peripheral circuits; Like power-off control circuit, SDRAM, FLASH, clock RTC or the like, these are prior art, are not detailing.The inventive point of the utility model is being double-current sampling computation chip with: described a plurality of computation chips.The model of said double-current sampling computation chip is BL6501A.This chip can sample respectively live wire and neutral line current, when two current errors surpassed 2.5%, showing had electricity filching behavior or false wiring, and the FAULT pin sends AIS, and according to big in two an electric currents current value metering.
Described multiuser electric energy meter also comprises a remote communication module, and described remote communication module is connected with microprocessor.The model of said remote communication module is 73M2901A.
Below only be described, but can not be interpreted as it is restriction claim with regard to the most preferred embodiment of the utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of in the protection domain of the utility model independent claims, being done are all in the protection domain at the utility model.
