[0074] (32) Timing disinfection mode: according to the set time interval (for example, 6 hours / 12 hours / 24 hours, etc., which can be set arbitrarily within the range of 1 to 24 hours), the main control module sends a signal to start disinfection to the UVC disinfection module after receiving the timing signal from the timer module, and the UVC disinfection module starts the UVC disinfection work for the set time period;
[0075] (33) Remote control disinfection mode: The remote control module receives a remote control signal and sets the working parameters of the main control module, or remotely controls the main control module to send a disinfection start signal to the UVC disinfection module. The UVC disinfection module starts the UVC disinfection work at the remotely set disinfection time according to the control signal, or sends a disinfection status signal to the remote control terminal in real time for the remote control terminal to view in real time;
[0076] (4) After executing any one of steps (31) to (33), the system returns to the initial state.
[0077] Further, such as Figure 3 As shown, the process of multi-directionally sensing the door switch state and determining whether there is someone in the car in step (1) specifically includes the following steps:
[0078] (11) The door switch sensing module senses the door switch action in real time, and transmits the door switch state signal to the main control module for feedback; if the door is switched, after the sensing detects that the door is closed, the process proceeds to step (12);
[0079] (12) The in-vehicle moving body sensing module detects whether there is a moving body in the vehicle, and transmits a moving body status signal to the main control module to determine whether there is someone in the space outside the seat in the vehicle; if a moving body is detected in the vehicle, it is determined that there is someone in the vehicle; otherwise, the process proceeds to step (13);
[0080] (13) The seat human body sensing module detects whether there is someone sitting on each seat in the vehicle, and transmits the seat seating status signal to the main control module to determine whether there is someone sitting in the vehicle; if it is detected that there is someone sitting on the seat in the vehicle, it is determined that there is someone in the vehicle; otherwise, it is determined that there is no one in the vehicle, and the UVC disinfection module can start the disinfection work.
[0081] Embodiment 2:
[0082] like Figure 4As shown, the difference between the intelligent automobile automatic disinfection system of this embodiment and the embodiment one is that the in-car human body sensing module is different from the embodiment one. In this embodiment, the in-car human body sensing module includes a camera moving body detection module and a camera human body recognition module; the camera moving body detection module is correspondingly arranged at different positions in the space inside the intelligent automobile, including corresponding to each door, each seat and each middle channel, and is used to dynamically detect the switch status of the door and whether there is a moving body in the car through the camera, and transmit the switch status of the door and the moving body detection signal to the main control module to preliminarily determine whether there is a moving body in the car; the camera human body recognition module is used to identify and determine whether the moving body in the car is a human body, so as to finally determine whether there is a person in the car.
[0083] Correspondingly, such as Figure 5 As shown, the disinfection method of the intelligent automobile automatic disinfection system of this embodiment is different from that of the first embodiment in that: the process of multi-directionally sensing the door switch state and determining whether there is someone in the car in step (1) includes the following steps:
[0084] (11') The camera moving body detection module dynamically detects the opening and closing action of the door through the camera, and transmits the door opening and closing state signal to the main control module for feedback; if the door is opened and closed, the process proceeds to step (12') after detecting that the door is closed;
[0085] (12') The camera moving body detection module detects whether there is a moving body in the car through the camera, and transmits the moving body status signal to the main control module to preliminarily determine whether there is a moving body in the car; if the detection senses that there is a moving body in the car, it is determined that there is a person in the car; otherwise, enter step (13');
[0086] (13') The camera human body recognition module is used to identify and determine whether the moving object in the car is a human body, so as to ultimately determine whether there is someone in the car; if the moving object in the car is identified as a human body, it is determined that there is someone in the car; otherwise, it is determined that there is no one in the car, and the UVC disinfection module can start the disinfection work.
[0087] The remaining features of this embodiment are the same as those of the first embodiment.
[0088] In the present invention, the working logic of induction and feedback is different from the conventional induction-action feedback mode. The conventional induction-action mode is: when the human body enters the sensing range, the working module is turned on and used; while the present invention is a reverse thinking, reverse use, when the human body enters the sensing range, the UVC disinfection module is turned off, and only when the human body leaves the sensing range can the UVC disinfection module be controlled to start working. Therefore, the present invention is a technical solution of unconventional thinking.
[0089] The intelligent automobile automatic disinfection system of the present invention overcomes the defects and shortcomings of the prior art. The human body sensing module in the car senses the door switch state and whether there is anyone in the car in multiple directions. Only when the door is closed and it is determined that there is no one in the car, a signal to start disinfection will be sent to the UVC disinfection module according to the set parameter instructions or the instructions sent by the remote control module, ensuring that the disinfection operation is carried out when there is no one in the car, avoiding accidental injury to the human body by the UVC disinfection module; utilizing the characteristics of short-wave UVC ultraviolet rays with sterilization and disinfection effects, ultraviolet rays can irradiate bacteria, viruses and other microorganisms It radiates and destroys the molecular structure of DNA and RNA in the cells of microorganisms, causing DNA chain breaks and cross-linking ruptures of nucleic acids and proteins, resulting in growth cell death and regenerative cell death, achieving the effect of sterilization and disinfection. It has the advantages of broad spectrum, high efficiency, rapid and thorough, no need to add chemical agents, no drug resistance, and no secondary pollution. Therefore, the intelligent automobile automatic disinfection system of the present invention does not require manual on-site operation, is fully automatic and intelligent, self-perceived and judged, can be monitored throughout the process, and automatically disinfects during the idle time of the vehicle. It is safe and harmless to the human body, and is especially suitable for use in driverless cars, including driverless taxis.
[0090] In the automatic disinfection method for a smart car of the present invention, multi-directional sensing is adopted for the door switch status and whether there is someone in the car. When the door is open or it is determined that there is someone in the car, the UVC disinfection module is instructed not to work or to stop the disinfection work immediately. Only when the door is closed and it is determined that there is no one in the car, can the disinfection work be carried out, ensuring that disinfection is only carried out when there is no one in the car and it is closed, which not only ensures personal safety, but also ensures the high efficiency of closed disinfection. Therefore, this method also has the above-mentioned beneficial effects of the automatic disinfection system.
[0091] The present invention can be widely applied to the field of intelligent vehicles.
