Preferably, the temperature detection circuit comprises a first temperature switch SK1, a second temperature switch SK2 and a temperature trigger sub-circuit; the first temperature switch SK1 and the second temperature switch SK2 are located outside the housing of the first capacitor C1 and the second capacitor C, respectively.

Because the temperature sensing surfaces of the two temperature switches SK1 and SK2 are tightly attached to the outer heating surfaces of the two capacitors C, C1, the temperature of the two capacitors can be monitored in real time, when the capacitor C or the capacitor C1 generates heat due to damage, and the temperature exceeds a certain threshold (such as 65 ℃), the temperature sensing surface of the temperature switch is heated and then the internal contact thereof is closed, the positive polarity end of the 220V alternating current power supply is connected with the 1 pin of the time control switch A2, so that the time control switch A2 is electrified to work, under the action of the internal circuit and the set time of the power output by the 3 and 4 pins, the 3 and 4 pins of the time control switch A2 output power to the buzzer B at a certain interval, the buzzer B is electrified at a certain interval and sounds, the capacitance value of the capacitor operated by the operator at present is not reduced or damaged temporarily, but the quality difference temperature is increased, so that serious consequences such as explosion and the like can be generated subsequently. The buzzer sounds at a certain interval, so that the condition that a working person does not hear the alarm sound and does not switch the capacitor at one time, and the running capacitor continues to rise in temperature and is seriously failed is effectively prevented. After hearing the sounder B, the worker can press the corresponding power switch to separate the current running capacitor from the wiring end of the motor, so that the other capacitor is connected into the motor, the normal work of the motor is ensured, and the problem of fault amplification is prevented.
Preferably, the speed regulation control circuit comprises a first relay K1, a second relay K2 and a voltage regulation sub-circuit; wherein, the relay is an alternating current relay. The power supply input ends of the first relay K1 and the second relay K2 are connected with the positive polarity end of an alternating current power supply, and the power supply output ends of the first relay K1 and the second relay K2 are connected with the signal interaction end of the voltage regulating sub-circuit. The voltage regulation sub-circuit comprises a bidirectional thyristor VS, a neon tube DI, a first resistor R2, a second resistor R3, a third resistor R4, an adjustable resistor RP, a third capacitor C3 and a fourth capacitor C4; the first main electrode of the bidirectional thyristor VS is a signal interaction end of the voltage regulation sub-circuit, the first main electrode of the bidirectional thyristor VS is connected with one end of a third resistor R4, and the other end of the third resistor R4 is connected with a fixed end of an adjustable resistor RP; the fixed end is connected with the sliding end, the other fixed end of the adjustable resistor RP is simultaneously connected with one end of a second resistor R3 and one end of a fourth capacitor C4, the other end of the second resistor R3 is connected with one end of a neon tube DI and one end of a third capacitor C3, the other end of the neon tube DI is connected with one end of a first resistor R2, the other end of the first resistor R2 is connected with a control electrode of a bidirectional thyristor VS, and a second main electrode of the bidirectional thyristor VS is simultaneously connected with the other end of a third capacitor C3 and the other end of a fourth capacitor C4.
Specifically, the trigger angle of the thyristor VS is determined by the product of the adjustable resistor RP, the resistor R4 and the capacitor C4, and the resistance value of the adjustable resistor RP is adjusted to be relatively small by adjusting the rotation speed of the motor, so that the charging time of the capacitor C4 is shortened, and the trigger angle of the thyristor moves forward, so that the voltage entering one capacitor terminal or the other capacitor terminal of the motor is relatively high, the working voltage of the motor is relatively high, and the rotation speed of the motor is relatively increased. When the resistance value of the adjustable resistor RP is adjusted to be relatively large by adjusting the rotating speed of the motor, the charging time of the capacitor C4 is prolonged, the trigger angle of the controllable silicon is moved backwards, the voltage entering one capacitor terminal or the other capacitor terminal of the motor is relatively low, the working voltage of the motor is relatively low, and the rotating speed of the motor is relatively reduced.
Preferably, the voltage regulation sub-circuit further comprises a fourth resistor R1 and a fifth capacitor C2; one end of the fourth resistor R1 is connected to one end of the third resistor R4, the other end of the fourth resistor R1 is connected to one end of the fifth capacitor C2, and the other end of the fifth capacitor C2 is simultaneously connected to the second main electrode of the triac VS, the other end of the third capacitor C3, and the other end of the fourth capacitor C4.
Specifically, a resistor-capacitor circuit composed of a resistor R1 and a capacitor C2 of the speed regulation control circuit is used for absorbing instantaneous peak voltage and preventing the bidirectional triode thyristor from being damaged during overvoltage. The speed of the motor can be adjusted through the action of the speed adjusting control circuit, and then the barrier gate of the security check machine entrance guard is adjusted to be opened or closed at a proper speed.
Due to the fact that the two power switches and the two capacitors are arranged, when the motor cannot work due to the fact that the capacitors are damaged in the working process of the security inspection machine, or when the security inspection machine works abnormally due to the fact that the capacity of the capacitors is reduced, a worker can quickly switch the other capacitor through the power switch to supply power for the motor of the security inspection machine. When the temperature of the capacitor is overhigh, the temperature detection circuit sounds through the buzzer at the first time to prompt a worker to switch another capacitor, so that the normal work of the motor and the security check machine is ensured. Meanwhile, the speed of the motor is regulated according to the commuting condition of the security check machine, and the purpose of saving electric energy is achieved on the premise of meeting the requirement of full commuting.
