The control unit 130 controls the heating device 300 to heat the lens through the image processor 120, the serializer and the deserializer.
Specifically, there are three ways to heat the lens:
the first is heating controlled by an intelligent terminal APP. After the user selects the heating function in the setting menu of the intelligent terminal APP, the intelligent terminal 700 transmits the heating control signal to the communication unit 110, the communication unit 110 transmits the heating control signal to the image video processor 120, the image video processor 120 transmits the heating control signal to the control unit 130, the control unit 130 receives the heating control signal, generates an execution signal based on the heating control signal and transmits the execution signal to the image video processor 120, the execution signal in the image processor 120 is converted by the deserializer and the serializer in the camera link, and then the function of the heating device 300 for heating the lens is started. The same approach can also realize the functions of stopping heating, etc.
Second, heating is controlled by a touch screen, and the user controls heating of the mirror by touching the touch screen 411 in the display unit 400 of the mirror system 10. Specifically, a control icon may be displayed on the touch screen 411, a user may display a control interface when touching the control icon, and the user may select to heat the lens 221 in the left sensing unit 220 or the lens 211 in the right sensing unit 210 on the control interface, so as to start a heating function and generate a heating control signal. Both the left display screen 410 and the right display screen 420 have deserializers therein, and the heating control signal is converted by the deserializers and the serializers in the display screen link and transmitted to the image video processor 120. The image video processor 120 transmits the heating control signal to the control unit 130, the control unit 130 generates an execution signal based on the heating control signal and transmits the execution signal to the image video processor 120 after receiving the heating control signal, and the execution signal in the image video processor 120 starts the function of the heating device 300 to heat the lens after being converted by the deserializer and the serializer in the camera link. The same approach can also realize the functions of stopping heating, etc.
The third is that the temperature sensor starts heating by itself. When the temperature sensor identifies that the physical environment temperature of the lens is lower than a preset first temperature threshold value, a heating control signal is automatically generated, the heating control signal is converted by a serializer and a deserializer in a camera link and then transmitted to the image video processor 120, the image video processor 120 transmits the heating control signal to the control unit 130, the control unit 130 generates an execution signal based on the heating control signal and transmits the execution signal to the image video processor 120, and the execution signal in the image video processor 120 is converted by the deserializer and the serializer in the camera link and then starts the function of the heating device 300 for heating the lens. When the physical environment temperature of the lens is higher than the preset second temperature threshold, the temperature sensor can automatically start and stop heating and other functions in the same way.
The storage unit 920 is connected to the image video processor 120, and is used for storing and reading data in the image video processor 120.
The power supply unit 910 is respectively connected to the heating power supply unit 800, the CAN transceiver 500, the storage unit 920, the control unit 130, the communication unit 110, the image video processor 120, the deserializer 250 and the serializer 430, and is configured to supply power to the respective units of the rearview mirror system 10 and maintain the operation of the rearview mirror system 10.
By providing the communication unit in the controller unit, the user CAN still control the heating device in the rearview mirror system 10 through, for example, the intelligent terminal 700 without being affected by the distance when the user is away from the intelligent cockpit central control car 740 and the car CAN-FD gateway 730; meanwhile, the user CAN also get away from the intelligent cabin central control car 740 and the car CAN-FD gateway, and directly control the heating device in the rearview mirror system 10 through the touch screen 411 in the left display screen 410; in addition, the temperature sensor can also identify the ambient temperature of the camera, and the automatic control heating device is realized. For example, when the temperature is lower than a preset first temperature threshold, a signal is transmitted to the controller unit 100 to enable the control unit 130 to control the heating device 300 to heat the camera, and when the temperature is higher than a preset second temperature threshold, a signal is transmitted to the controller unit 100 to enable the control unit 130 to control the heating device 300 to stop heating the camera, so that the convenience of operation is further improved through multiple control modes.
