The process that rail electric car of city of the present invention travels under the support of corresponding electric power system is as follows:

When rail electric car in travelling along running route, the first vehicle-mounted control producer 81 of rail electric car is by current conduction single track 2 during near current reception responser 4, then under the control of the break-make actuating station of current reception responser 4, make the receiving slave end of current power switch circuit 3 be switched on, when making the control circuit of current power switch circuit 5 in running order if the current port of control signal output ends of the front-end computer 5 of this moment is in the situation of the control signal that output can power, then the control circuit of current power switch circuit 5 is controlled the control end of current power binistor after by the receiving slave end by the control signal of its control signal output ends output and is made the conducting of current power binistor, 1 of power cable begins to power to current conduction single track 2 by the current power binistor, is powered to electric car in-to-in electric power system by first shoegear 82 again; Meanwhile, current ground receive responser 4 on off mode signal output part forward end computing machine 5 the make-and-break signal input end when front port carry current conduction single track 2 be in the signal of electricity condition; After this signal is handled through front-end computer 5, carry the signal that to power from the place ahead the 3rd port of the control signal output ends of front-end computer 5 to the signal input end of connected the place ahead the 3rd power switch circuit 3, which kind of (just no matter connect between two ports of the receiving slave end of this power switch circuit 3 and make the control circuit of the place ahead the 3rd power switch circuit 3 be in off position with device, on circuit, do not have control signal yet and pass through, make that the place ahead the 3rd power switching device 3 can't conducting).

Along with rail electric car continues to travel a very short time along running route, the second vehicle-mounted control producer 84 on being arranged on rail electric car passes through current conduction single track 2 and during near current reception responser 4 up, then receive under the control of break-make actuating station of responser 4 on current ground, make the receiving slave end of current power switch circuit 3 be disconnected, and making current power binistor 3 become off state by conducting state, 1 of power cable stops to current conduction single track 2 power supplies; Meanwhile, current ground reception responser 4 carries current conduction single track 2 to be in the signal of power failure state by the front port of working as of the make-and-break signal input end of its on off mode signal output part forward end computing machine 5; After this signal is handled through front-end computer 5, the signal that one side can be powered from the place ahead the 3rd port signal input end conveying of the 3rd power switch circuit 3 forwards of the control signal output ends of front-end computer 5, and make that the control circuit of the place ahead the 3rd power switch circuit 3 is in running order; On the other hand then from the control signal output ends of front-end computer 5 carry the signal that can not power to the signal input end of the control circuit of current power switch circuit 3 when front port, and make the control circuit 3 of current power switch circuit be in off position.

In said process, rail electric car of the present invention is sailed in the route running following, electric power system usually only to rail electric car 2 conduction single tracks of the 1 conduction single track that comprises current conduction single track and rear adjacent of process power simultaneously; Make two conduction single tracks simultaneously charged and also to make rail electric car can obtain stable electric supply the problem that should consider be: should be able to be in time change conducting electricity the power supply of single track, also should consider electric car total length, conduct electricity the length, the distance between two vehicle-mounted control producers of single track and distance, the rail electric car between two shoegears and the vehicle-mounted control producer and charged conduction single track can be covered the inferior factor of electric car under steam.

In said process, have only the current conduction single track 2 that passes through under steam when rail electric car just might make it charged and maintenance a period of time, only that is to say that current conduction single track 2 could get after satisfying following two conditions: the one, the break-make actuating station that receives responser 4 when ground is in the state that the receiving slave termination of current power switch circuit 3 is logical, and the 2nd, the control circuit of current power switch circuit 3 is in running order.This mode logically be " with " relation, thereby guaranteed the reliability of electric power system of the present invention to the power supply control of conduction single track.

In said process, should satisfy charged conduction single track and be covered requirement under the rail electric car all the time, those conduction single tracks that leave at rail electric car should be not charged like this, thereby help the safety of system's operation.Like this should to the quantity of the position of length, the length of rail electric car of conduction single track, two vehicle-mounted control producers, shoegear and position and a row rail electric car by the time simultaneously charged conduction single track radical select.In concrete enforcement, following consideration can be arranged:

The quantity of the shoegear on the rail electric car of the present invention is generally two, and these two shoegears are electrically connected.In the process of laying omnidistance interrupted conductor rail, the length of single track 2 of respectively conducting electricity that is adopted generally is identical.One row rail electric car length may be thought of as between 30 to 80 meters and (also can be set separately by the different situations of city size, the magnitude of traffic flow, the density of population and passengers quantity), the length of conduction single track 2 then can cover charged conduction single track principle under the electric car under steam according to rail electric car, and is in the position on the electric car and determines according to rail electric car length and two vehicle-mounted control producers and two shoegears.A kind of scheme wherein be the length of conduction single track 2 be permutation rail electric car length 1/3 or be slightly less than 1/3 and be provided with.

The corresponding a kind of embodiment of scheme is therewith: the first vehicle-mounted control producer 81 is arranged on the front end of rail electric car, distance between first shoegear 82 and the first vehicle-mounted control producer 81 is slightly less than the length (for example length of 0.9 times conduction single track) of a conduction single track, distance between second shoegear 83 and first shoegear also is the length that is slightly less than a conduction single track, and the second vehicle-mounted control producer 84 and second shoegear 83 formerly upwards are arranged side by side at the rear.When rail electric car travels to the current ground reception of its first vehicle-mounted control producer 81 processes responser 4, the conducting of current power binistor, the electric supply that power cable 1 is provided is delivered to current conduction single track 2, the first shoegears 82 by the current power binistor and is subjected to behind the electricity electric supply to be delivered to the electric car electric power system.Subsequently, rail electric car travelled to first shoegear 82 and 83 whiles and current monorail track 2 contacted positions of second shoegear, had only the electric power system power supply of 1 pair of electric car of current conduction single track this moment.Again subsequently, rail electric car travels when its first vehicle-mounted control producer 81 receives responser 4 through the 1st ground, the place ahead, it is electric that the place ahead the 1st conduction single track is got, and the power supply mode of this moment is: simultaneously the electric car electric power system is powered by second shoegear 83 by first shoegear 82 and by current conduction single track by the place ahead the 1st conduction single track.When rail electric car continues to travel to the current ground reception of its second vehicle-mounted control producer 84 processes responser 4, the current power binistor turn-offs, thereby current conduction single track dead electricity, simultaneously current ground receives responser 4 makes the control circuit of current power switch circuit 3 quit work by front-end computer, also makes the control circuit of the place ahead the 3rd power switch circuit 3 start working.Mode so, feasible with respect to a rail electric car that is listed as in travelling, have only the adjacent conductive single track 2 under the covering of two velamen electric cars to be in electriferous state simultaneously, make a conduction single track in these two conduction single track the place aheads be in electriferous state soon, that is to say that to have only the control circuit of three power switch circuit that link to each other respectively with these three conduction single tracks in running order.This have only the in running order situation of two conduction single track control circuits charged, that have only three power switch circuit along with travelling of rail electric car dynamically changes forward, thereby guarantee every charged conduction single track all be in rail electric car below situation under, rail electric car can obtain the electric supply of steady and continuous and trouble-free operation.
