In order to facilitate the user to register and store the fingerprint data, in one implementation mode, a fingerprint collector and a storage unit are further arranged in the automobile, and the fingerprint collector and the storage unit are electrically connected with the processor 103.

Specifically, fingerprint sampler can be semiconductor fingerprint sensor, and semiconductor fingerprint sensor can divide into: the capacitance type sensor and the pressure-sensitive type sensor, and the semiconductor fingerprint sensor can improve the safety of the system.
The electronic signal sent by the capacitance sensor passes through the surface of the finger and the dead skin layer to reach the living skin layer (dermis layer) of the finger, the fingerprint pattern is directly read, and the fingerprint data is formed according to the difference between the ridge and the valley of the fingerprint pattern and the capacitance value formed by the semiconductor capacitance sensing particles.
The pressure-sensitive sensor forms fingerprint data by sensing the deformation of the semiconductor pressure-sensitive medium material unit, when a finger is placed on the surface of the pressure-sensitive sensor, the ridge of the fingerprint can form pressure on the pressure-sensitive unit, the pressure-sensitive unit is deformed, and the resistance value can be changed, so that the voltage change is caused. The valley does not generate stress in the corresponding cell, so its corresponding resistance value does not change. Digital information of ridges and valleys on the fingerprint pattern can be formed through different voltage values, and fingerprint data can be obtained.

the filter can filter the amplified signal to obtain a filtered signal, and the filtered signal is sent to the comparator; the comparator can compare the reference voltage value of the control component with the analog voltage value of the filtering signal, and if the reference voltage value is greater than the analog voltage value, the comparator sends a current reduction signal to the triode and sends a refrigeration signal to the processor; if the reference voltage value is smaller than the analog voltage value, sending a current increasing signal to the triode and sending a heating signal to the processor; the triode reduces the current output to the control part after receiving the current reduction signal; increasing the current output to the control part after receiving the current increase signal; the processor sends a refrigeration signal to the control component after receiving the refrigeration signal; after receiving the heating signal, sending the heating signal to the control part; after receiving the refrigeration signal, the control component reduces power by using the obtained current so as to reduce the temperature of the vehicle-mounted air conditioner; upon receiving the heating signal, power is increased using the obtained current to raise the temperature of the vehicle air conditioner.
The amplifier may be a circuit with a signal amplification function, for example, a fully differential operational amplifier circuit, or a single differential operational amplifier circuit, and the filter may be a circuit with a filtering function, and the filter may filter out infrared noise in the amplified signal, and may be composed of a capacitor, an inductor, a resistor, and other components. The comparator may be a circuit having a comparison function, may compare the analog voltage signal with a reference voltage, and may be a voltage comparator, a zero-crossing voltage comparator, or the like. The triode is a semiconductor triode, also called a bipolar transistor and a transistor triode, which is a semiconductor device for controlling current and can increase the output current and also can reduce the output current.
The reference voltage can be the voltage value of the control component, the control component can be an air conditioner compressor, and when the control component receives a refrigeration signal, the obtained current is reduced current, so that the power of the control component can be correspondingly reduced to realize the reduction of the temperature of the vehicle-mounted air conditioner; when the control component receives the heating signal, the obtained current is the increased current, so that the power of the control component can be correspondingly increased to realize the temperature increase of the vehicle-mounted air conditioner.
