Embodiment 1
[0021] The principle of this embodiment, such as figure 1 As shown, an automobile air-conditioning automatic control system includes a microcontroller, and a sensor, a display, a key device, and an actuator respectively connected to the microcontroller, and the microcontroller is also connected to a fault storage and diagnosis device. The present invention adds a fault storage and diagnosis device on the basis of the existing automatic control system of the automobile air conditioner, and the fault storage and diagnosis device is directly connected with a microcontroller. The sensors include the evaporator temperature and humidity sensor and the interior temperature and humidity sensor, and the actuators include the evaporator motor controller and the compressor motor controller. When the evaporator temperature and humidity sensor or the interior temperature and humidity sensor regularly collects the temperature or humidity data It is transmitted to the microcontroller, an...
Embodiment 2
[0023] In this embodiment, on the basis of Embodiment 1, a power supply device is further added, and the power supply device is a storage battery device, such as figure 2 As shown, the storage battery device is directly connected with the microcontroller to ensure the continuous power supply of the automatic control system of the automobile air conditioner. Other parts of this embodiment are the same as those of Embodiment 1, and will not be repeated here.
Embodiment 3
[0025] In this embodiment, an automatic alarm device is further added on the basis of Embodiment 2, such as image 3 As shown, the automatic alarm device is directly connected with the microcontroller. When the refrigerant in the automatic control system of the automobile air conditioner is insufficient, the refrigeration pressure is high or lower than the set value, etc., the automatic alarm system will automatically send out an alarm signal to prompt Notice. Other parts of this embodiment are the same as those of the foregoing embodiment, and will not be repeated here.
