Abstract
The invention discloses a control method of compressors for a push-pull type motor train unit, which is used for separately controlling two compressors located in a main train and two compressors located in a secondary train in the motor train unit. The control method for the push-pull type motor train unit can achieve the technical effects of reasonably collocating the utilization rate of the compressors, reducing noise generated to a cab at an operation end by the compressors in work, and reducing the influence of frequent starting and stopping of the compressors on the service life of the compressors.
Description
Technical field
The present invention relates to be used for a kind of control method of push-pull type motor train unit, specifically is compressor control method.
Background technology
The push-pull type motor train unit are made up of two locomotives of head and the tail and middle passenger car, and classification type is: L+nT+L, and wherein, L is a locomotive, and T is a passenger car, and n is an integer, is the quantity of passenger car.Compressor is set on the locomotive mainly is to train braking system and other wind path control system wind regime is provided.
Disposing 2 compressors at head and the tail respectively on two locomotives, the push-pull type motor train unit are totally 4 compressors, and compressor is arranged in the Machine Room of locomotive near driver's cab and two positions of afterbody.As shown in Figure 2, when needing compressor operating, compressor button 7SK drops into, and through pressure controller (blast is being lower than setting value or is being higher than setting value meeting auto-closing or disconnection), compressor a starts working, compressor b devotes oneself to work behind the time-delay 3s, by the heavily connection relay on another locomotive of network transmission control, 2 compressors on another locomotive are devoted oneself to work in the same manner, select strong pump pattern, be that 4 compressors can be devoted oneself to work simultaneously equally, mode such as Fig. 2.Train is when normal operation, and 4 compressors can be worked simultaneously, and it is very short to beat the wind time, causes 4 compressors to open, stop frequently, influences service life.Can strengthen the noise of driver's cab after the compressor input near the compressor of driver's cab.
Summary of the invention
The object of the invention aims to provide a kind of control method that is used for the push-pull type motor train unit, can reach following technique effect: the degree of utilization of reasonable disposition compressor; The noise that when reducing compressor operating the operating side driver's cab is produced; And reduce the influence of high frequent start and stop to the compressor life-span.
The technical solution used in the present invention: a kind of control method that is used for the push-pull type motor train unit, be characterised in that, two compressors that are positioned at main car in the motor train unit are controlled separately respectively with being positioned at from two compressors of car:
During normal the operation, turn back in service back and forth at motor train unit, be arranged in main car and from the compressor operating of car away from driver's cab one end, and turning back back and forth along with motor train unit, compressor is switchover operation in twos, guaranteed that like this locomotive no matter at which direction running, all by the compressor operating away from operator's compartment one end, has reduced the noise of locomotive.
When needs high wind, be positioned at main car and move simultaneously from four compressors of car;
When certain compressor breaks down, this compressor is isolated, do not influence all the other compressor operatings.
The advantage or the good effect that are brought by technique scheme have:
During 1) owing to normal operation,, compare, obviously reduced the noise of driver's cab with the compressor operating near driver's cab in the prior art by compressor operating away from driver's cab;
When 2) normally moving, a main car and compressor operating is respectively arranged from car; When turning back; when changing to another locomotive as the operating side; main car and switch to another compressor operating the canyon simultaneously from car; 2 compressor alternations on the locomotive have been guaranteed like this; compared with the prior art, on the basis of redundancy compressor degree of utilization configuration more reasonable, the frequent start-stop of compressor can reduce greatly; the time of the each work of compressor can prolong, and helps prolonging the life-span of compressor.

The specific embodiment
As shown in Figure 1, 2, the compressor in the described push-pull type motor train unit comprises main car compressor a (3) and the main car compressor b (4) that is positioned at main car 1 head and the tail two ends respectively, be positioned at from car 2 from beginning to end two ends from car compressor a (5) with from car compressor b (6).
The operation of control end control compressor starts, at first main car compressor b (4) work, main car compressor b (4) breaks down, when being isolated, main car compressor a (3) devotes oneself to work, if main car compressor a (3) et out of order again, compressor a (3) can be isolated equally.Main car compressor start signal is transferred to from car by network, from car compressor a (5) work, when car compressor a (5) fault is isolated, devote oneself to work from car compressor b (6), if from car compressor b (6) et out of order again, compressor b (6) can be isolated equally.
When above-mentioned design can guarantee normal operation, main car or from car a compressor operating is arranged all even 2 whole faults of compressor of a locomotive are isolated, also can guarantee the compressor endure on another locomotive, can not cause the wind regime disappearance of permutation car.
Strong pump pattern is set on the locomotive, requires this moment to beat wind fast, promptly require whole compressors to devote oneself to work, under the strong pump pattern, 4 compressors are all worked, and any compressor fault all can be isolated.
The driver upgrades to main car from car after changing to other end operation, and main car is downgraded to from car, and the compressor control pattern is identical.At this moment, the compressor operating pattern is still the compressor operating of main vehicle tail end, from the compressor operating of headstock portion, has so just guaranteed the push-pull type motor train unit in the operation of turning back back and forth, 2 compressor alternations on every chassis.At this moment, strong pump pattern is still 4 compressors and all works.
The control principle of compressor as shown in Figure 3, the control command of compressor is imported the LCU (Local Control Unit) of main car behind pressure controller, through the main car starting compressor of output control after the logic operation of main car LCU, if main car compressor b (4) fault, isolate the main car compressor a in back (3) work, simultaneously, the compressor control command signal is transferred to from car by network, undertaken exporting control from the car starting compressor after the logic operation by LCU from car, if from car compressor a (5) fault, isolate the back and work from car compressor b (6).The main car LCU of strong pump instruction input, main car LCU exports control and at first starts main car compressor b (4) after logic operation, behind the time-delay 3s, start main car compressor a (3), simultaneously, strong pump signal is transferred to from car LCU by network, at first starts from car compressor a (5) from car LCU output, delay time after 3 seconds, starting is from car compressor b (6).Under the strong pump pattern, 4 compressors are all worked, and any compressor fault all can be isolated.
During practice, can move above-mentioned control method automatically by operational procedure in the compressor control end.
