Background technology
Short distance traffic guideway vehicle, particularly subway obtain electric energy by the current colector be disposed near vehicle chassis very frequently, described current colector by resilient slide block from bus duct (" 3. the track ") received energy being disposed in rail side.In these guideway vehicles with the current colector within the scope of vehicle chassis, be provided with multiple this current colector very frequently, because one side distributes electric power thus and each current colector must transmit less power respectively, need to arrange multiple current draw position owing to generally there being the bus duct of interruption on the other hand, so that can these spaces of bridge joint, vehicle be powered on whole section.If current colector disappearance (such as break or otherwise damaged), also can continue operational vehicle so thus.Be transferred by remaining current colector at this electric energy.This running state is disadvantageous for electric apparatus, particularly current colector to the circuit of bus, because described electric apparatus suffers the load improved enduringly.This running state can not be found out easily for navigating mate, because ride characteristic does not change and the current warning device not used for this defect thus.In addition, particularly the problem be present in subway be that MTR network utilizes direct current (DC) to run usually.This direct current (DC) is produced by general energy supply system by electronic rectifier, and wherein these rectifiers generally can not feed back.If run the modern vehicle that can feed back on such railway division, ground, when so only having the customer when the energy that can consume feedback to be simultaneously and to activate, just advantage can be obtained.Electric energy that is unnecessary, that produced by braking procedure is inevitable be converted into heat when following in braking resistor, and namely this electric energy is not by needed for the vehicle accelerated in the same time mutually.This low efficiency causes the cooling requirement of other shortcoming, the superheated as tunnel and the raising to compartment or station.Reduce the partly success of these shortcomings, this can take into account by the overall control wherein travelling operation.Such as can postpone starting of a vehicle until other car brakeing is to reduce overall energy requirement in this wise at this.But, can not the accurate magnitude of power finding out each vehicle in operation travelled, drive current transformer can report its current power value to vehicle control device if desired.But this is inadequate for the whole optimization travelling operation.
Summary of the invention
Therefore the present invention based on task be that a kind of electrically operated guideway vehicle is described, it is confirmable and this guideway vehicle provides current colector Failure Alarm that total energy ezpenditure of this guideway vehicle or energy produce in traveling is run.
This task is solved by the electrically operated guideway vehicle with the feature of claim 1.Favourable configuration is the theme of dependent claims.
Basic thought according to the present invention describes a kind of electrically operated guideway vehicle, this guideway vehicle comprises at least one and is disposed in the current colector within the scope of vehicle chassis and the electric line between current colector and connection box, wherein in the distribution of electric line, be furnished with current measuring device, this current measuring device is determined the electric current that flows in the line and the signal corresponding to intensity of current is sent to analytical equipment.
Following advantage can be realized thus, namely can determine current flow and therefore consumption of power or the power stage of guideway vehicle at the run duration of guideway vehicle continuously.At this particularly advantageously, electric power is realized by the measurement in one or more feed-in position, can realize the detection accuracy rate significantly higher than the current measurement by usually existing at driving current transformer place thus.By the detection in feed-in position, the consumption of power of assistive drive (such as air-conditioning or compressed air compressor) and car lighting also can be detected.
According to the present invention, current measuring device is arranged in the electric line between current colector and connection box (or terminal point), and this current measuring device detects the electric current flowed in this circuit.For this reason, can use current converter that is common, that be applicable to guideway vehicle on the one hand, the railway (such as subway) run for vdc on the other hand needs dc voltage changer.It is important that this current measuring device is arranged on this position, can determine total energy ezpenditure or the Energy transmission of this guideway vehicle.Such guarantee, vehicle-mounted other the customer of guideway vehicle is involved in measurement.
One embodiment of the present invention specify, distribute a current measuring device respectively to each current colector, this current measuring device determines the electric current flowing through respective collector.
Another embodiment of the invention specifies, is equipped with common circuit and utilizes current measuring device to determine the electric current flowed in the circuit that this is common to respectively current colector relative on longitudinal direction of car side.Following advantage can be realized thus, namely can realize the saving of device.This is particularly favourable when current colector being arranged in bogie truck place, because so only need the connection flexibly between the hard-wired part in car body place at moveable bogie truck and electric line.
The electric current detected by one or more current measuring device is directed into analytical equipment, and wherein proportional with detected intensity of current signal is sent to this analytical equipment.Ensured by the design of the current measuring device (current converter) being suitable for railway in this electromotive force separation generally needed and enough isolation.Analytical equipment by the current magnitude of voltage of the current measurement value and the supply of railway energy that are sent to this analytical equipment to the braking electric energy of the feedback of the instantaneous electric power consumption or vehicle of determining guideway vehicle.
In other improvement project of the present invention, be provided with vehicle control device, this vehicle control device carries out the control task of higher level.This vehicle control device is incorporated in operation control system, and this operation control system controls whole railway operation and the current position of each vehicle, motoring condition (speed, acceleration/accel, loading etc.), energy ezpenditure or Energy transmission are travelled as controlling when following traveling plan the input parameter run by this operation control system energetic optimum.Such as a train can be delayed by from rolling away from of halting point at short notice when other vehicle will sail into before halting point at once, makes the braking electric energy of the vehicle stopped can be used to the vehicle accelerating to start.
Can realize thus the whole railway network peak energy consume remarkable minimizing, thus can less and therefore cost determine the size of corresponding electric supply installation (voltage transformer, rectifier) lowlyer.
The favourable characteristic of another kind of the present invention is the simple identifiability that current colector lost efficacy.The overall energy requirement of guideway vehicle also can be transmitted by one or more remaining current colector when collector damage (fracture).But occur the larger intensification of this current colector and electric line at this, this reduces the life-span of these devices.Therefore the identification of the inefficacy of current colector is important.Equally, the sinking (being separated from bus duct) be desirably performed defectively or not of current colector may cause the overload of remaining current colector.According to prior art, in order to identify that this running state can arrange terminal switch at current colector place, the position (contact or sinking) of described terminal switch detected set electrical equipment.But such terminal switch suffers environmental conditions and needs specific maintenance.
According to the present invention, electrically operated guideway vehicle is equipped with current colector to lose efficacy and identifies, this current colector lost efficacy the inefficacy identifying and can identify current colector without the need to moveable, maintenance intensive and the device of taking up wear.To this, analytical equipment is equipped with discriminator, and this discriminator compares at the electric current flowed in each circuit of current colector.If there is difference at this, this difference exists on (longer) time period determined, and wherein has value zero to the electric current of the current colector determined, so analytical equipment detects the inefficacy of this current colector.That this is determined, the longer time period (typically several seconds) is important, to avoid mistake to export, because there is the interruption of the short time that electric current is carried at the crossover position place of bus duct and the warning that should not lead to errors of this situation.
Specific value obtained it is recommended that the current colector identified to vehicle control device report lost efficacy, because this vehicle control device can avoid the running state determined thus, described running state may be harmful for remaining current colector.The maximum acceleration of the guideway vehicle be fully loaded with particularly can be avoided at this.
Realizing the inefficacy simply and reliably identifying (or multiple) current colector along with using one aspect of the present invention, vehicle can be kept in use until suitable repair time point and but do not exceed electricity and hot operational limit.On the other hand, the operation optimized due to the energy ezpenditure providing accurate magnitude of power in real time and can realize the railway network of guideway vehicle according to the present invention.
