Two, serious threat is to the safe operation of cable line: electric power facility tends to cause cable line fault in the theft tunnel, if handle untimely even can be because of cable line generation arc discharge generation fire; Shenyang in addition taken place thief in the cable tunnel by the electric shock after burnt to death, almost cause the situation of fire in the tunnel;
Three, live in the people in the electric power tunnel: the electric power well lid is opened easily, even make electric power tunnel become lumpen home, State Grid Corporation of China, Shanghai Power Company and Shenyang Utilities Electric Co. found in inspection once all that social blind influx is lit a fire and cooked, formed serious disaster hidden-trouble in the tunnel;
Four, the electric power tunnel resource is illegally occupied: the electric power tunnel resource is an infrastructure very valuable in the urban construction, along with developing rapidly of city, in order to reduce cost, to utilize electric power tunnel to lay communication line and has just become a kind of selection.In the electric power tunnel throughout the country, the companies such as Netcom, telecommunications, Tie Tong that take place through regular meeting open give out light the steathily situation of cable of electric power tunnel, remain incessant after repeated prohibition, and the tunnel space resource is illegally occupied, and has formed new disaster hidden-trouble;
Five, constructing tunnel managerial confusion: because the many families of management of electric power tunnel one family use at present, and social unit in charge of construction is various, cause the standard construction of some unit in charge of construction not according to standard, private draws the situation of leaving about outstanding in the tunnel, cause the tunnel management confusion, major network path resource is occupied, has caused the significant wastage of tunnel resource, has caused very big hidden danger for the stable operation of tunnel inner cable circuit.
For this reason, the radio alarming technology has appearred on the market: internal battery, after receiving the signal that sends by sensing unit when the warning master controller, wake the GSM transmitter module up, by predefined transfer address, packet is sent the zone that its wireless transmission coverage is covered for all GSM networks.
The problem that this technology exists is: battery is under rugged surroundings, and electric quantity consumption is very fast, nominal can with the electric weight in 1 year can be in 1,2 month very fast consumption light; Battery and gsm module under rugged surroundings, job insecurity; Outer well lid is a metal material, causes signal shielding, can't realize real-time monitoring, can run out of battery electric quantity sooner, can't satisfy the production needs.
Summary of the invention
The purpose of this utility model is exactly can not in time to find in order to solve in the present electric power tunnel violations of rules and regulations, thereby the problem of avoiding accident to take place, provide a kind of have simple in structure, easy to use, can effectively monitor electric power tunnel, pinpoint the problems early, avoid the power cable multimode supervisory system of advantages such as accident generation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of power cable multimode supervisory system, it comprises real-time monitoring platform, this platform is connected with a plurality of substation equipments by fiber optic local area network, each substation equipment bus by separately respectively is connected with data acquisition unit in several are installed in electric power tunnel, and each data acquisition unit is connected with corresponding sensor unit respectively again; Each substation equipment also is connected with several fiber optics by optical fiber simultaneously, and each fiber optic then is connected with a plurality of PD sensors respectively.
Described real-time monitoring platform comprises that database server, voice device, note device and computing machine connect to form.
Described substation equipment comprises cable local discharge monitoring main frame, electric power multimode monitoring host computer and remote power feeding transmission system composition, wherein cable local discharge monitoring main frame is connected with each fiber optic by optical fiber, and electric power multimode monitoring host computer is connected with sensor unit by bus.
Described sensor unit comprises level sensor, current sensor, temperature sensor, harmful gas sensor, air oxygen level sensor and controller of fan, they are connected with the corresponding data acquisition device respectively, and each data acquisition unit then is connected with electric power multimode monitoring host computer by the CAN-BUS bus.
The beneficial effects of the utility model are: the enforcement by the monitoring of cable multimode, will further improve the integral level of cable system on-line monitoring, and then lay the foundation for carrying out the work of city cable net state on-bne repair.Improving the cable system power supply reliability, reduce the cable power off time, reduce cable operating maintenance manpower and materials expense, there are huge economic benefit and social benefit in aspects such as raising cable system operation ability.
