System for reading meter by short message

Abstract

The invention relates to a short message ammeter reading system, which comprises a plurality of short message collective reading machines and a system management center, wherein, the short message collective reading machines are connected to a plurality of energy meters for collecting electric energy data and connected to a system management center; the short message collective reading machines respectively comprise a single-chip microcomputer module, a signal processing module and a GSM module; and the single-chip microcomputer module, the signal processing module and the GSM module are connected with each other in sequence. The short message ammeter reading system adopts a wireless public network technique, utilizes an existing mobile communication network and transmits data through the short message mode so as to realize the automatic ammeter reading and monitoring in a transformer area and a buyer of heavy electricity. The invention has the advantages of simple structure and convenient maintenance, thus lowering the cost and promoting the automatic level of electricity using in electricity sectors.

Description

technical field [0001] The invention relates to a short message meter reading system, in particular to a short message meter reading system for large users. Background technique [0002] At present, in the power market at all levels, it is common for some large power consumers in the power sector to steal electricity, which has brought large economic losses to the power supply and sales companies. Such users are generally large electricity consumers who use high-voltage power supply. The load side of the transformer adopts high-voltage metering. The metering points are often outdoors, and the users are relatively scattered. It is very inconvenient to use traditional wired methods or power line carrier methods for automatic meter reading monitoring. . [0003] Moreover, the traditional wired meter reading and monitoring systems currently on the market only perform meter reading and monitoring, and need to lay separate lines, so the utilization rate is low. In the transforma...

[0002] At present, in the power market at all levels, it is common for some large power consumers in the power sector to steal electricity, which has brought large economic losses to the power supply and sales companies.

Such users are generally large electricity consumers who use high-voltage power supply. The load side of the transformer adopts high-voltage metering. The metering points are often outdoors, and the users are relatively scattered. It is very inconvenient to use traditional wired methods or power line carrier methods for automatic meter reading monitoring.

[0003] Moreover, the traditional wired meter reading and monitoring systems currently on the market only perform meter reading and monitoring, and need to lay separate lines, so the utilization rate is low.

In the transformation of the power grid in some places, although the optical cable network from the power bureau to each substation has been realized, the cost of laying optical cables to each transformer is too high

The cost of the system for meter reading and monitoring using the power carrier is too high, and the cost of each power carrier supermeter monitoring system is tens of thousands.

In addition, the system that uses wireless for meter reading and monitoring can use wireless frequency bands for data transmission, but the cost of building and maintaining a dedicated wireless data network for a region or city is also very high
