Description
Technical field
The present invention relates to that a kind of railway passenger train, subway train carriage vehicle or city rail passenger vehicle vehicle are supplied power and the security control and the managing power consumption device of electricity consumption in upkeep operation, relate in particular to a kind of passenger vehicle car inspection and repair surface power supply power supply monitoring system.
Background technology
At present; A plurality of vehicles were linked to be row when vehicle was reorganized and outfit upkeep operation in car inspection and repair unit; The power supply major part of power consumption equipment is supplied power through the surface power supply power supply on the vehicle; And same surface power supply power supply need be supplied power to different trains at different time, and the multiple row car is then supplied power by the surface power supply power supply of a plurality of correspondences on different station tracks.
Fig. 1 is on the station track that is formed by rail 14, by 1
# Vehicle 501,2
#Vehicle 502 ... 20
#The power supply sketch map of the train that vehicle 520 is formed.When the power customer need use or overhaul the equipment (like ventilation equipment such as air-conditionings) on the vehicle; At first couple together through electric connector 3 and stube cable 2 power taking aviation socket and surface power supply power sourced electric cabinet 1 the vehicle afterbody by the power customer; Confirming to connect under correct with the safe situation then; The close air switch of surface power supply power sourced electric cabinet 1 of power customer; And press the closed contactor of " startup " button, supply power to the permutation vehicle by the surface power supply power supply, with operation and the maintenance electricity consumption of satisfying various power consumption equipments on the vehicle; After electricity consumption finished, the power customer pressed " outage " button on the surface power supply power sourced electric cabinet 1, and the air switch of leaving behind breaks off electric connector 3, and electricity consumption finishes.Under this confession power mode; When vehicle is reorganized and outfit upkeep operation in car inspection and repair unit; When electricity consumption of power customer, with how many electricity, how to guarantee that Electrical Safety etc. decided in its sole discretion by the power customer fully; Be full handwork fully, do not take any technology or management means that power customer's the electricity of taking is monitored and managed, cause problems such as electricity consumption waste and Electrical Safety hidden danger easily.Simultaneously because vehicle is reorganized and outfit maintenance in car inspection and repair unit is frequent the generation; Therefore common send electricity or power failure to power supply unit generally guarantees safety with the operation order system; But this operation order system can't really effectively be carried out and guarantee safety, has reduced overhaul efficiency simultaneously.
Specifically have following four shortcomings in the prior art: whose record automatically send electric people when 1. overhauling a train of vehicles is, if manual record then can reduce car inspection and repair work efficient; 2. technically do not control sending electric people to send electricity to operate in, also not audit to sending electric people to carry out identity, any people that can touch surface power supply power sourced electric cabinet can operating equipment accomplishes send the electricity operation; 3. send electric people when sending electricity, possibly have other maintainers being about to operation on charged circuit or the equipment, and other maintainers send the situation of electricity unclear to being about to, this possibly cause serious accident; 4. the surface power supply power supply is supplied power to different vehicles in different time; The power supply of surface power supply power supply just to as if changing; Very inconvenient with a certain train of vehicles one shared electric weight of how much spending of general kilowatt-hour meter statistics maintenance; Be difficult to realize that quantitative statistics overhauls the energy consumption of a certain train of vehicles, be not easy to realize the fine-grained management of energy consumption, thereby possibly cause the waste of electricity consumption.
Existing at present " distribution box supervisory control system ", " power monitoring system of factory " can remote monitoring and the electricity consumption situation of adding up permanent plant, also can remote activation or arrestment.This type systematic uses " electrical quantity acquisition module " or " power monitoring module " through wired or wireless net connection; The electricity consumption situation of remote collection power equipment or power consumption equipment; Like voltage, electric current, power, power consumption etc.; But the power supply that these systems monitored to as if fixing, it is not distinguished the power supplier, these systems are not distinguished the various power object yet simultaneously.
Chinese patent " a kind of system and operation method that power supply station's operation conditions is monitored in real time " (application number 200510096061.3), " energy management system and the method thereof that are used for controller switching equipment " (application number 200610023875.9), " a kind of universal power distribution monitoring system that is used for power distribution cabinet " (application number 200710073698.X), " operation power stops sending electric computer supervisory control system " (patent No. 200720010474.X) all are the monitoring that are used for fixing power consumption equipment; These system side overweight the control to the collection of electricity consumption situation data or load; To sending electricity operation not carrying out any technical monitoring or control; These systems are neither distinguished the power supplier simultaneously, also the various power object are not distinguished.
