The saving of device can be realized.This is favourable particularly in the case where current-collector is arranged at bogie, because this
Sample only needs the flexible connection between moveable bogie and the part being fixedly mounted at car body of electric line.
The electric current detected by one or more current measuring devices is directed into analytical equipment, wherein with the electricity that is detected
The proportional signal of intensity of flow is sent to the analytical equipment.The potential separation generally required herein and enough isolation pass through suitable
Together in the current measuring device of railway（Current converter）Design ensure.Analytical equipment is by being sent to the analytical equipment
Current measurement value and the current magnitude of voltage of railway energy supply determine the consumption of the instantaneous electric power of rail vehicle or vehicle
Feedback braking electric energy.
Vehicle control device is provided with the alternatively improved scheme of the present invention, the vehicle control device carries out the control of higher level
Task.The vehicle control device is incorporated into operation control system, and the operation control system controls whole railway operation and should
Operation control system is by the current position of each vehicle, transport condition（Speed, acceleration, loading etc.）, energy expenditure or
Energy output as the input parameter for controlling running operation in the case where following traveling plan energetic optimum.Such as one
Train can be delayed by a short time from rolling away from for stop when other vehicle will be driven into before stop at once,
The braking electric energy of the vehicle to stop is allowd to be used to accelerate the vehicle started.
It is possible thereby to realize the whole railway network peak energy consumption substantially reduce, it is possible thereby to it is smaller and therefore into
This determines corresponding electric supply installation lower（Transformer, rectifier）Size.
Another favourable characteristic of the present invention is the simple identifiability of current-collector failure.The total energy of rail vehicle
Amount demand can also be in collector damage（Fracture）In the case of transmitted by one or more remaining current-collectors.However,
There is the larger heating of the current-collector and electric line in this, and this reduces the life-span of these devices.Therefore the knowledge of the failure of current-collector
It is not important.Equally, current-collector defectively or be not desired to the sinking that strategic point is performed（Separated from bus-bar）It may cause
The overload of remaining current-collector.According to prior art, in order to identify that the running status can set terminal to open at current-collector
Close, the position of the limit switch detection current-collector（Contact is sunk）.However, such limit switch by environmental condition simultaneously
