[0038] In the embodiment, the communication mode between the air conditioner panel controller and the air conditioner controller is CAN communication, the air conditioner evaporative fan adopts PWM speed regulation, and one air conditioner evaporative fan is arranged on the left side and one air conditioner evaporative fan is arranged on the right side in the passenger car, and the left side and the right side air conditioner evaporative fans work simultaneously.

[0040] In the embodiment, the air conditioner switch is a general switch for controlling the ozone generator, the air conditioner evaporative fan, the air exchange fan and the air conditioner fresh air system.

[0041] Before the ozone generator works, the air conditioner controller controls the air exchange fan and the air conditioner fresh air system to work for 3 minutes to exchange the air in the passenger car, so as to avoid the situation that the air in the passenger car is too dirty after the passenger car stops running.

[0042] Further, the hand brake switch, the passenger door and the combination instrument controller are further included, the combination instrument controller is used to collect the hand brake switch state and the passenger door state, and sends the hand brake switch state and the passenger door state to the air conditioner panel controller.

[0044] Further, the buzzer is further included, and the air conditioner controller is further used to send an operation instruction to the buzzer to control the buzzer to beep until the ozone generator stops working after the operation instruction is sent to the ozone generator.

[0045] In order to prevent the presence of outsiders while the ozone generator is working, a buzzer is arranged in the embodiment, and the buzzer is used to remind the outsiders to leave the passenger car as soon as possible.

[0046] Further, the air conditioner panel controller is further used to detect the state of the sterilization switch after each power-on, and when the initial state of the sterilization switch is closed and the state of the sterilization switch is detected again to be opened, it is determined that the sterilization switch is valid.

[0047] The air conditioner panel controller detects the sterilization switch after each power-on, thereby avoiding the occurrence of the situation that the sterilization switch is not closed last time and is accidentally turned on this time.

[0048] Further, the air conditioner panel is further included, and the air conditioner panel controller is further used to send an instruction to the air conditioner panel to control the air conditioner panel to display a start sterilization countdown before sterilization and to display a boarding countdown after sterilization.

The air conditioner panel displays a safe boarding countdown: 5 minutes.

[0053] Embodiment two

[0054] The embodiment discloses a passenger car air conditioner integrated air sterilization and disinfection control method.

[0055] As shown in Figure 2 A control method of a passenger car air conditioner integrated air sterilization and disinfection control system based on the passenger car air conditioner integrated air sterilization and disinfection control system of embodiment one, comprising the following steps:

[0056] The air conditioner panel controller collects the state of the sterilization switch and the state of the air conditioner switch, and when the sterilization switch is valid and the air conditioner switch is in a closed state, sends a running instruction to the air conditioner controller.

[0057] The air conditioner controller receives the operation instruction sent by the air conditioner panel controller, controls the ventilation fan and the air conditioner fresh air system to work for a set time before sterilization.

[0058] The combination instrument controller collects the hand brake switch state and the passenger door state, and sends the hand brake switch state and the passenger door state to the air conditioner panel controller.

[0059] The air conditioner panel controller receives the hand brake switch state and the passenger door state, judges whether the hand brake is effective and whether the passenger door is closed, and sends a start sterilization instruction to the air conditioner controller when the hand brake is effective and the passenger door is closed.

[0060] The air conditioner controller receives the start sterilization instruction, sends an operation instruction to the ozone generator to control the ozone generator to work for a set time, and at the same time sends an operation instruction to the air conditioner evaporative fan to control the air conditioner evaporative fan to blow ozone into and diffuse throughout the entire passenger car for a set time while the ozone generator is working, and then sends an operation instruction to the ventilation fan and the air conditioner fresh air system to control the ventilation fan and the air conditioner fresh air system to work for a set time to dissipate the ozone in the passenger car.

[0061] Specifically, the static sterilization process is as follows:

[0062] As shown in Figure 2 , the air conditioner panel controller detects whether the sterilization switch is effective after each power-on, and this step is to avoid the case that the sterilization switch is not closed in time after the last sterilization. When the air conditioner panel controller detects that the initial state of the sterilization switch is closed and then detects that the air conditioner is turned on, the ventilation process before sterilization is performed, and the air conditioner panel controller sends an operation instruction to the air conditioner controller to control the ventilation fan and the air conditioner fresh air system to work for a set time before sterilization.

[0063] In order to ensure the safety and effectiveness of the entire passenger car sterilization process, the hand brake switch state and the passenger door state need to be collected to prevent the car from rolling away. At this time, the combination instrument controller collects the hand brake switch state and the passenger door state, and sends the hand brake switch state and the passenger door state to the air conditioner panel controller. The air conditioner panel controller receives the hand brake switch state and the passenger door state, judges whether the hand brake is effective and whether the passenger door is closed, and sends a start sterilization instruction to the air conditioner controller when the hand brake is effective and the passenger door is closed.

[0064] The specific process of passenger car sterilization is as follows:

[0065] The air conditioner controller controls the ozone generator to work for 10 minutes, and the ozone generator generates 1000 mg / h at the same time. The air conditioner evaporative fan works, and the peak buzzer starts to alarm (30 seconds of beeping at first, and then 15 seconds of beeping every 1 minute until the ozone generator stops working and the beeping stops).

[0066] After the ozone generator stops working, the air-conditioning evaporative fan is closed after a 20s delay;

[0067] After the ozone generator stops working, the air-conditioning panel controller sends a command to the air-conditioning panel, and the air-conditioning panel displays the countdown for getting on the bus.

[0068] The air-conditioning controller sends a running command to the air-exchange fan and the air-conditioning fresh air system, controls the air-exchange fan and the air-conditioning fresh air system to work for a set time, and makes the ozone in the passenger car dissipate.
