Description

The long-range monitoring system of electric substation of electrically-based line carrier communication

Technical field

This utility model relates to monitoring system of electric substation, is specifically related to the long-range monitoring system of electric substation of a kind of electrically-based line carrier communication.

Background technology

Power industry is most important basic energy resource industry in the national economic development, and the power that transformer station transmits as electric power, heart, its importance is self-evident.Therefore the monitoring security protection of transformer station is worked and also become ever more important.Traditional monitoring, mainly to the monitoring in transformer station peripheral (suffering violence damage) etc..Personnel on site that circuit own and potential safety hazard are then needed repairing checks, this has resulted in the great wasting of resources.

Transformer station's voice monitoring device of a kind of electrically-based carrier communication disclosed in the patent document that patent is CN203849854U, namely speech data is gathered by acquisition module, after CPU processes, it is sent to terminal server by PLC, this patent has the drawback that transmission data mode is excessively single, collection data are single, once occur that circuit damages, then cannot be carried out the transmission of speech data.

Summary of the invention

For the problems referred to above, this utility model provides the long-range monitoring system of electric substation of a kind of electrically-based line carrier communication, is possible not only to transformer station is played certain supervisory function bit, and the fault to simple circuit, it is possible to it is actively discovered, initiative alarming.

For achieving the above object, this utility model adopts the following technical scheme that

The long-range monitoring system of electric substation of electrically-based line carrier communication, including control room and collection terminal；

Control room includes central server, Surveillance center's PC, the first single-chip microcomputer, GPRS module, electrical quantity processing module and power line carrier module, described Surveillance center PC, GPRS module, electrical quantity processing module and power line carrier module are connected with the first single-chip microcomputer respectively；

Collection terminal includes second singlechip, GPRS module, memory module, voice acquisition module, electrical quantity acquisition module, temperature sensor and power line carrier module；Electrical quantity acquisition module is for gathering the voltage of circuit, electric current in power transformation box, and temperature sensor is for gathering the real time temperature in power transformation box；GPRS module, memory module, voice acquisition module, electrical quantity acquisition module, temperature sensor and power line carrier module are connected with second singlechip respectively；Communicated by GPRS module or power line carrier module between control room and collection terminal.

Preferably, the first single-chip microcomputer also includes display lamp, keyboard and clock circuit.

Preferably, second singlechip also includes keyboard and clock circuit.

Preferably, GPRS module is used for realizing getting online without being tethered to a cable, and adopts the CMS91 of Cello company.

Preferably, clock circuit adopts the DS1302 trickle charge clock chip of Dallas company.

This utility model obtains and provides the benefit that:

Circuit structure is simple, avoid substation secondary wiring, layouted by multi-faceted, realize gathering non-blind area, add GPRS module, it is ensured that double data transmits, and by installing electrical quantity acquisition module, can also carry out the situation of electric power gathering in time reporting, it is to avoid investigation blindly and the waste of human resources.

Accompanying drawing explanation

Fig. 1 is system structure composition diagram of the present utility model.

Detailed description of the invention

For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.

Owing to GPRS is the wireless, packet-switched technology of a kind of GSM based on second generation mobile communication system, it is particularly well-suited to interruption, paroxysmal or frequently, a small amount of data transmission, it is also applied for data traffic transmission once in a while, although current communication technology has updated 3G and 4G communication, but because GPRS connects for providing between mobile subscriber and data network, user is always online, charge by flow, relatively other charge situations, GPRS is selected to greatly reduce cost of serving, therefore this programme have selected GPRS technology, certainly, it is not excluded that, when improving other conditions, can according to selecting other such as zigbee, 3G and 4G etc. other be conducive to the data transfer mode that this programme implements.

In this programme, second singlechip may be disposed in power transformation box, and it is that described single-chip microcomputer is powered by the civil power in this power transformation box through decompression voltage regulator.Single-chip microcomputer is arranged in power transformation box, main frame can not only be avoided to be destroyed by people, and the power supply of power transformation box can be directly utilized and electric lines of force carries out communication, simultaneously, it should be noted that voice acquisition module, can one or several being arranged on power transformation box, electrical quantity acquisition module and temperature sensor simultaneously can also be arranged on each position of power transformation box according to this, or is arranged in other power transformation boxes by wiring.

This programme utilizes GPRS module transmission voice data, power line carrier, PLC module is utilized to carry out remote data transmission, circuit structure is simple, need not connect up at substation secondary, layouted by multi-faceted, it is achieved gather non-blind area, and by installing electrical quantity acquisition module, can be acquired reporting to the situation of electric power, it is to avoid the waste of investigation blindly and human resources.

Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
