General power supply department all is to hang a distribution line of manual drawing this area on the wall to move towards figure now; Be stained with a lot of various signs in the drawings, promptly can not show actual geographical position, load and the fault that can not intuitively observe, monitor the electrical network actual motion; The reason great majority of fault still rely on manual work to go could confirm after the field observation; So the fault feedback speed is slow, much after the caller client words, faults such as power failure takes place have just been known; So in management, also be easy to make a mistake, field data can not be understood by leading and managing department at once; Add the electrical network long-term work under natural environment; Bear vibration, season rainwater and sunshine, the influence of expanding with heat and contract with cold etc.; Be easy to cause the loosening and loose contact etc. of the aging and equipment jointing of equipment; The administrative staff of electrical network can not observe directly again, and electrical network is also carrying same electric current (even also possibly carry bigger electric current) simultaneously; Will cremate because of loose contact makes the heating of equipment point or produces electricity like this, burn out dropping of equipment, tripping operation, voltage ripple of power network and power failure and electric line, also possibly cause fire and life safety, bring tremendous loss to economy; Bring huge obstruction to social development.Therefore; Need to combine the intelligent digital automation of electric network reconstruction Project Realization electrical power trans mission/distribution system; Let the administration of power networks personnel can Direct observation and the voltage of keeping watch on each section and each user side on the electrical power trans mission/distribution system circuit; Electric current and power to improve the managerial skills of transmission and distribution network, provide the high-quality electric energy for vast power consumer is continual.
Movingization of power transmission and distribution intelligent digital automated system distribution control centre, intelligent digital automation control terminal and data communication network are formed.Data communication system is the tie that main station system connects with equipment for power transmission and distribution, and intelligent digital automation control terminal is the basis of data collection, data processing and execution control.Over past ten years, many electric companies distribution automation system that put into operation just being arranged, generally is at distribution transformer, on-pole switch, switching station relevant terminal to be installed; Mostly communication channel is the optical fiber mode, and it is huge that main station system is built, and comprises traditional SCADA, GIS, advanced applied software etc.; So just cause the distribution automation system investment big, system builds complicated, and utilance is low; Degree of being practical is not high, has caused the system product of poor efficiency with high investment.
Summary of the invention
The utility model is big to the investment of available technology adopting optical fiber mode system, and system builds complicated, and utilance is low, and the shortcoming that degree of being practical is not high proposes a kind of transformer station terminal remote data communication system.
The technical scheme of the utility model is, transformer station's terminal remote communication system comprises data acquisition equipment, signal transmitting terminal, signal receiving end, and said signal transmitting terminal adopts the GPRS router, and said signal receiving end adopts the device with GPRS receiver module.
As the further improvement of the utility model, said data acquisition equipment adopts integrated PLC device.
As the further improvement of the utility model, said signal receiving end is that mobile phone is or/and GSM/GPRS MODEM.
Further improvement as the utility model is characterized in that, said integrated PLC device links to each other with said GPRS router through the RJ45 Ethernet interface.
As the further improvement of the utility model, said GPRS router communicates through the IPSec vpn tunneling based on GPRS network with the device with GPRS receiver module.
The beneficial effect of the utility model is, to the present situation of electric company, through lower input, comes to obtain in real time the running status of power distribution network; To reduce the failure rate of electrical network, reduce the interruption duration of electrical network, ensure the safe, reliable of operation of power networks; On communication modes, discard the optical-fibre communications mode, use the GPRS communication mode of common wireless channel; Need not the investment construction wireless network, communication coverage is big, and the client device installation is convenient; Overall cost is low, and each operation can send to the form of note on the switch user and attendant's mobile phone of appointment, and attendant and user can be gone and found out what's going in real time.
