The principle of work of the air source purifier for locomotives controller of the present embodiment and working process are as following:

110V direct supply on locomotive is respectively from No. 1 and No. 2 terminals inputs of control unit interface J1, and pressure switch YK signal is from No. 4 terminals inputs of control unit interface J1.Controller is controlled energising and the power-off of the first electropneumatic valve by the 7th interface J7 in the first executive circuit 6; Controller is controlled energising and the power-off of the second electropneumatic valve by the 8th interface J8 in the second executive circuit 7.

Controller is controlled and is switched on and off power supply by the K switch 1 of power circuit 1.The power circuit 1 of controller electric after, the locomotive 110V direct supply of input is at 1 point of two-way of power circuit: after the filter circuit filtering that a road forms through diode D1 with by resistance R 1, capacitor C 1, capacitor C 2, be input to DC110V/DC12V power module U1; D1 plays and external power isolation and anti-error-polarity connection effect.U1 output DC12V direct supply is input to the input end of three terminal regulator U2 after capacitor C 3, capacitor C 4 filtering, and the DC5V power supply VCC of U2 output is for the each circuit on the control circuit board of circuit arrangement; Another road is through diode D2, after capacitor C 10 High frequency filters, offer with the first executive circuit 6 in the first electropneumatic valve of joining of the 7th interface J7 and use with the second electropneumatic valve that the 8th interface J8 in the second executive circuit 7 joins.

In the time that the air compressor on locomotive starts, pressure switch YK closure, air compressor cranking signal (110V d. c. voltage signal) is from the 4 pin inputs of the interface J1 of controller; The signal of input is input to 1,2 pin of photoelectrical coupler U5 to ground after resistance R 3, R4, R5, R29 current limliting (cut-off current is within the scope of 4-5mA); 3, the 4 pin conductings of photoelectrical coupler U5,13 pin of the triggering reverser U4F of integrated schmidt trigger change active potential into from high potential, its 12 pin saltus step is immediately high potential, corresponding P1.4 end (5 pin) high potential that is input to micro controller system U3, micro controller system U3 starts according to this signal determining air compressor.

Micro controller system U3 is according to internal processes, successively from P1.0 end (1 pin) and P1.1 end (2 pin) output signal (Low level effective), when P1.0 end output low level, be input to 1 pin of the triggering reverser U4A of integrated schmidt trigger by resistance R 7, after paraphase, export high level from 2 pin, this level is leaded up to resistance R 9 current limlitings and is outputed to 2 pin of the 5th interface J5, lights the first indicator lamp; Another road flow into 1,2 pin of photoelectrical coupler U6 to ground through resistance R 11,4 of photoelectrical coupler U6,3 pin conductings, the base stage voltage to ground of aerotron Q3 is similar to 0, aerotron Q3 cut-off, 110V voltage is added to the grid of field effect transistor Q1 after by R21, R13 current limliting in parallel, due to zener diode D5(12V in parallel between the grid of being on the scene effect pipe Q1 and source electrode), thereby field effect transistor Q1 gate-voltage limit, at 12V, is prevented to over voltage damage field effect transistor Q1; Now Q1 conducting, 110V voltage flows out from 2 pin of the 7th interface J7 after flowing into the first electropneumatic valve by 1 pin of the 7th interface J7, then is flow to and held by drain electrode, the source electrode of field effect transistor Q1.In the time that 2 pin of the P1.1 of micro controller system U3 are low level, its control circuit principle to the second electropneumatic valve is same as described above.

When micro controller system U3 normally moves, set by internal processes, its P1.5 holds 6 pin output low levels, after paraphase, export high level from its 10 pin to 11 pin of the triggering reverser U4E of integrated schmidt trigger by resistance R 19, the warning indicator lamp being now connected with the 4th interface J4 is because 1 pin of J4 connects VCC+5V voltage, so warning indicator lamp can not be lighted.When micro controller system U3 is during because of certain reason work mal, its P1.5 holds 6 pin will export high level, and 2 pin that are reacted to J4 will become low level, and the warning indicator lamp that J4 connects is lighted, and fault alarm indication is provided.

Micro controller system U3 preferably adopts the advantage of AT89S51 series monolithic to be: take timer internal T0 to carry out self-clocking to the time, manpower-free debugging, avoids analogous circuit by realizing by repeatedly debugging.SCM program programming, in EPROM, can be revised, and program write through encrypt after be difficult for being replicated.The realization of the control software in micro controller system U3 mainly comprises: adopt timing mode: in principal function, define, timer T0 works in timing mode 1, the every 50ms of timer produces once and interrupts, interrupt altogether 20 times, be just 1S, every 1S counting 1 time, during T1, amount to several instruction cycles that are for 72 times, (P1.0 holds low level to send during this period corresponding instruction, P1.1 holds high level), then continue to count up to 90 times, in 18 times cumulative countings, for next instruction cycle T 2, (P1.0 holds high level to send during this period corresponding instruction, P1.1 holds high level), continue again next counting, in the time counting up to 162, in 72 times cumulative countings, for another next instruction cycle T 1, (P1.0 holds high level to send during this period corresponding instruction, P1.1 holds low level), continue again next counting, in the time counting up to 180, in 18 times cumulative countings, for another next instruction cycle T 2, (P1.0 holds high level to send during this period corresponding instruction, P1.1 holds high level), so far the complete whole repetition period of controller.When completing after last repetition period, the counting machine of micro controller system U3 is clear 0, automatically repeats to start the above instruction cycle.

Controller is in same cycle of operations T, and " energising " to the first and second electropneumatic valves and " power-off " they are mutually to restrict, but the time unequal, but keep a difference T2, make two electropneumatic valves have " dead electricity " overlapping time.Within two electropneumatic valve dead electricity overlapping times, due to the first and second two chain controls of dry decontamination tower, can not enter adsorbed state simultaneously, therefore, though the first electropneumatic valve has stopped the regeneration of the first dry decontamination tower, as long as the second electropneumatic valve must not be electric, the second dry decontamination tower can not enter adsorbed state, the second dry decontamination tower still continues to keep adsorbed state, just starts conversion until the second electropneumatic valve obtains electric rear two towers.This function of controller, will make wind regime dry cleaner obtain " flexible conversion " characteristic, claim again " flexible translation function ".

When a cycle of operations does not also complete and the control signal of pressure switch YK while interrupting (power-off), also interruption of work immediately of controller, stops timing.In the time that the control signal of pressure switch YK recovers (again electric), controller timing will add up on former work-hours, just change until complete this cycle of operations.In the time that cycle of operations interrupts, controller is remembered its mode of operation to be deposited, and in the time of lower task, still continues by previous status.Be former electric electropneumatic valve still electric, still dead electricity of the electropneumatic valve of former dead electricity, until this cycle of operations completes.

In sum, the air source purifier for locomotives controller of the present embodiment, by photoelectrical coupler being set at signal input circuit, the cranking signal of the 110V voltage of pressure switch input and follow-up single chip machine controlling circuit are isolated, can effectively isolate the impulsive disturbance of locomotive electric apparatus loop various electromagnetic signals in service, thereby improve the functional reliability of controller of the present invention; Conversion and control by adopting 89C51 microprocessor, two dry decontamination tower work-hourses in single chip machine controlling circuit by program Solidification in chip, time conversion does not need to modulate setting by traditional potential device, improve the accuracy of controller time conversion, it controls first, second dry decontamination tower work-hours and the error of flexible transfer time is ± 0.3s (be respectively ± 7S of standard schedule error of the Ministry of Railways, ± 1.8S); Automatic Memory mode of operation function after controling appliance has air compressor to shut down, refresh memory in the time that air compressor is resumed work, works on according to the mode of operation before shutting down, and cumulative hours error is ± 0.5s; By photoelectrical coupler being set respectively at first, second output control circuit, thereby effectively by the safe and reliable isolation of 110V operating voltage of single chip machine controlling circuit and first, second executive circuit, guarantee the safety of micro controller system, further improved the safe and reliable property of controller of the present invention; By working station indicator and warning indicator lamp and interlock circuit thereof are set, can grasp easily the mode of operation of two dry decontamination towers, and whether controller breaks down to process in time; Program setting by micro controller system and utilize Schmidt trigger trigger characteristic to avoid the impact of external interference signal, does not cause circuit erroneous action, has further improved the reliability of system works, has simplified circuit simultaneously yet.
