The automatic control car washing and manual control car washing processes are introduced by combining the circuit in the embodiment.
First, the flow of automatic car washing is described, referring to fig. 4:
(1) detecting that a vehicle enters through a vehicle detection module;
(2) through the automatic control and time module, the vehicle washing platform is automatically started, and the time relay is reset to start timing;

(5) if not, the vehicle detection module detects the vehicle running-out condition in real time, and starts alarming when detecting that the vehicle runs out, the vehicle washing platform is automatically stopped, and the time relay finishes timing.
The flow mainly comprises two processes, namely the action when the vehicle enters and the action when the vehicle exits:
1. when the vehicle enters, the vehicle inspection device I1 is closed for a period of time, namely the time when the vehicle passes through the vehicle inspection device I1, and the vehicle is opened when the vehicle completely enters, and the following actions are sequentially generated during the period of time, namely the coil of the relay KA2 is electrified, the contact of the relay KA2 is closed, the coil of the time relay SJ1, the coil of the time relay SJ2 and the coil of the relay KA1 are electrified.
When the coil of the relay KA1 is electrified, the three contacts of the relay KA1 are all closed, the first contact of the relay KA1 is closed, the coil parallel circuit is continuously electrified, and the situation that the circuit is disconnected due to the fact that the contact of the relay KA2 is disconnected after a vehicle leaves the detection range of the vehicle detector I1 is avoided; the second contact of the relay KA1 is closed, putting the line part connected to the flush module in communication; the third contact of relay KA1 is closed, completing the circuit portion connecting the alarm module.

2. When the vehicle runs out, the second vehicle detector 2 is closed for a period of time, namely the time when the vehicle passes through the second vehicle detector 2, and when the vehicle completely runs out, the second vehicle detector is opened, and in the period of time, a coil of the time relay SJ3, a coil of the relay KA3 and a coil of the time relay SJ4 are electrified and divided into two conditions:
a. the car washing time does not reach the preset time
When the coil of the time relay SJ3 is electrified, the coil is connected with the contact of the second automobile inspector 2 in parallel for 1 second and then is attracted, and then is disconnected after 10 seconds, so that the coil of the time relay SJ3, the coil of the relay KA3 and the coil of the time relay SJ4 are continuously electrified in 10 seconds, and the power failure caused by the fact that the automobile completely runs out and the second automobile inspector 2 is disconnected is prevented.
When the coil of the relay KA3 is electrified, the contact is attracted, and because the contact does not reach 2 minutes at the moment, the third contact of the relay KA1 is still closed, the line where the alarm 3 is located is connected for alarming, and the prompt personnel do not reach the car washing time, so the time relay SJ3 also has the functions of preventing the circuit from being disconnected and stopping the alarming in advance.
When the coil of the time relay SJ4 is powered on, the contact of the time relay SJ4 is disconnected in a delayed mode, the delay time is set to be 5 seconds for the time relay SJ2, the contact of the time relay SJ2 is disconnected after 5 seconds, so that the circuit connected to the flushing module is powered off, the coils of the contactor KM1 and the contactor KM2 are powered off, the contact of the time relay SJ1 and the contact of the contactor KM2 are disconnected, the circuit of the flushing module is disconnected, and the power is disconnected when.
b. The car washing time reaches the preset time
When the coil of the time relay SJ3 is electrified, the coil is connected with the contact of the second automobile inspector 2 in parallel for 1 second and then is attracted, and then is disconnected after 10 seconds, so that the coil of the time relay SJ3, the coil of the relay KA3 and the coil of the time relay SJ4 are continuously electrified in 10 seconds, and the power failure caused by the fact that the automobile completely runs out and the second automobile inspector 2 is disconnected is prevented.
When the coil of the relay KA3 is electrified, the contact is attracted, and because the time relay SJ1 is disconnected after 2 minutes, the coil of the relay KA1 is electrified, and the contacts are disconnected; relay KA1 first contact is open, so that the line connected to the flush module is de-energized, the coils of contactor KM1 and contactor KM2 are de-energized, so that their contacts are open, the flush module line is open, and car washing is stopped; the third contact of the relay KA1 is disconnected, so that the line where the alarm 3 is located is disconnected, and the alarm cannot be given out even if the contact of the relay KA3 is closed.
When the coil of time relay SJ4 is powered on, the contact of time relay SJ4 is disconnected in a delayed manner, and the disconnection of time relay SJ4 does not affect the circuit.
The manual car washing process comprises the following steps:
the change-over switch SA-1 is thrown to a terminal of a manual line, the line is communicated when the starting switch SB-2 is pressed, at the moment, a coil of the contactor KM1 and a coil of the contactor KM2 are electrified, corresponding contacts of the coil are closed, car washing is started, and as the second contact of the relay KA1 is connected to two ends of the starting switch SB-2 in parallel, when the coil is electrified and attracted, the starting switch SB-2 can be released, the line can be continuously conducted, and the work of workers is reduced; when the car washing is finished, the circuit can be disconnected by pressing the stop switch SB-1, and the car washing is stopped.
