Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
The motor speed reducing mechanism used by the existing security inspection machine works at a speed, the speed regulation purpose cannot be achieved, meanwhile, the matched capacitor used by the motor of the existing security inspection machine is only one, the security inspection machine is disabled after the quality is reduced or damaged after the motor is used for a long time, the motor speed reducing mechanism can be normally used only after maintenance personnel replace the capacitor, and therefore the motor speed reducing mechanism cannot be used for commuting in the time of shutdown maintenance, and the reliability and stability are low. Therefore, the application provides a single-phase motor control device for a security inspection machine, which is used for stabilizing the security inspection machine by connecting at least two capacitors between two capacitor terminals of a motor; meanwhile, by arranging a temperature detection circuit, the temperature of the capacitor at the motor side is detected in real time and an alarm is given, so that the safety of the system is improved; finally, a speed regulation control circuit is further arranged to regulate the rotating speed of the motor, so that the barrier gate of the security inspection machine gate is regulated to be opened or closed at a proper speed, and the purpose of saving electric energy can be achieved on the premise of meeting full commute.
In one embodiment of the invention, as shown in fig. 1 and 2, the single-phase motor control device for the security inspection machine comprises a control system body A1 of the security inspection machine, a single-phase motor M, a temperature detection circuit, a speed regulation control circuit, a first power switch S1, a second power switch S2, a first capacitor C1 and a second capacitor C. The two power input ends of the control system body, the two power input ends of the temperature detection circuit and the two power input ends of the speed regulation control circuit are connected with two ends of an alternating current power supply; two power supply output ends of the control system body are connected with two signal input ends of the speed regulation control circuit.
One end of the first capacitor C1 is simultaneously connected with one end of the second capacitor C, a first capacitor wiring end of the single-phase motor M and a first signal output end of the speed regulation control circuit, the other end of the first capacitor C1 is connected with one end of the first power switch S1, the other end of the second capacitor C is connected with one end of the second power switch S2, the other end of the first power switch S1 is simultaneously connected with the other end of the second power switch S2, a second capacitor wiring end of the single-phase motor M and a second signal output end of the speed regulation control circuit, and a third wiring end of the single-phase motor M is connected with a positive polarity end of an alternating current power supply.
Specifically, the number of the capacitors connected to the motor M side is at least two, the first capacitor C1 and the second capacitor C are nonpolar electrolytic capacitors, and the capacitance values of the first capacitor C1 and the second capacitor C are equal. The first power switch S1 and the second power switch S2 are interlocking key type key power switches, when one key is pressed, the other key is sprung, so that the two power switches S1 and S2 cannot be simultaneously connected with contacts, and a power switch handle is positioned outside the safety inspection machine electric control box shell. When the two capacitors C and C1 are in operation, if the capacity of one capacitor is reduced or damaged, the rotating speed of the motor is reduced or even not rotated, and then the gate inhibition barrier gate of the security inspection machine cannot normally rise and fall. According to the method, maintenance personnel do not need to find for maintenance, a worker directly presses one of the power switches S1 and S2, the other capacitor is connected, the motor can still work with the capacitor, the fact that the motor can be connected with the capacitor in good condition to work normally when one capacitor is damaged or performance is reduced is guaranteed, and the damaged capacitor or the capacitor with reduced capacity can be replaced when the follow-up security inspection machine is not used.
Compared with the prior art, the single-phase motor control device for the security inspection machine improves the stability of the security inspection machine by connecting at least two capacitors between two capacitor terminals of the motor; meanwhile, by arranging a temperature detection circuit, the temperature of the capacitor at the motor side is detected in real time and an alarm is given, so that the safety and reliability of the system are improved; the speed regulation control circuit is further arranged to regulate the rotating speed of the motor, so that the barrier gate of the security inspection machine gate is regulated to be opened or closed at a proper speed, and the purpose of saving electric energy is achieved on the premise of meeting the full commute.
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 respectively arranged outside the shell of the first capacitor C1 and the second capacitor C. The temperature triggering sub-circuit comprises a time control switch A2 and a sounder B; the first power input end of the time control switch A2 is simultaneously connected with one end of the first temperature switch SK1 and one end of the second temperature switch SK2, the other end of the first temperature switch SK1 and the other end of the second temperature switch SK2 are both connected with the positive polarity end of the alternating current power supply, the second power input end of the time control switch A2 is connected with the negative polarity end of the alternating current power supply, and the two power output ends of the time control switch A2 are connected with the two power input ends of the signaling device.
Specifically, the time control switch A2 is a microcomputer time control switch finished product of model KG316T, the time control switch A2 is provided with a liquid crystal display screen, seven cancel/restore, time correction, week correction, automatic/manual, timing and clock keys, two power input ends 1 and 2 pins, two power output ends 3 and 4 pins, after being electrified, the numbers displayed by the liquid crystal display screen are respectively operated by a user, the time of the two power output ends 3 and 4 pins outputting power can be set, the time control switch A2 has a memory function, and the power failure of an external power supply can not cause the change of an internally set time program as long as secondary setting and adjustment are not carried out.
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 temperatures of the two capacitors can be monitored in real time, when the capacitor C or the capacitor C1 is heated due to damage, and the temperature exceeds a certain threshold (such as 65 ℃), the internal contact of the capacitor C or the capacitor C1 is closed after the temperature sensing surface of the temperature switch is heated, the positive polarity end of the 220V alternating current power supply is connected with the 1 foot of the time control switch A2, so that the time control switch A2 is powered on, under the action of the internal circuit and the set 3 and 4 foot output power supply time, the 3 and 4 feet of the time control switch A2 can output power to the sounder B at certain intervals, and the sounder B can generate electricity and sound at certain intervals so as to prompt that the capacitor currently operated by staff is not reduced or temporarily damaged due to the poor quality temperature rise, serious consequences such as explosion can possibly occur later. The sounder sounds at certain intervals, so that the situation that the operational capacitor continues to be heated and has more serious faults caused by the fact that the staff does not hear the alarm sound at one time and does not switch the capacitor is effectively prevented. After hearing the sound of the signal sounder B, the worker can separate the current running capacitor from the wiring end of the motor by pressing the corresponding power switch, so that the other capacitor is connected into the motor, the normal operation of the motor is ensured, and the problem of fault expansion 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 input ends of the first relay K1 and the second relay K2 are connected with the positive polarity end of the alternating current power supply, and the power output ends of the first relay K1 and the second relay K2 are connected with the signal interaction end of the voltage regulation sub-circuit. The voltage regulating sub-circuit comprises a bidirectional triode 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 the second resistor R3 and one end of the fourth capacitor C4, the other end of the second resistor R3 is connected with one end of the neon tube DI and one end of the third capacitor C3, the other end of the neon tube DI is connected with one end of the first resistor R2, the other end of the first resistor R2 is connected with the control electrode of the bidirectional thyristor VS, and the second main electrode of the bidirectional thyristor VS is simultaneously connected with the other end of the third capacitor C3 and the other end of the fourth capacitor C4.
Specifically, the triggering angle of the thyristor VS is determined by the product of the adjustable resistor RP, the resistor R4 and the capacitor C4, when the resistance value of the adjustable resistor RP is adjusted to be relatively small by adjusting the rotation speed of the motor, the charging time of the capacitor C4 is shortened, the triggering angle of the thyristor moves forward, so that the voltage of one capacitor terminal or the other capacitor terminal entering 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 regulated to be relatively large by regulating the rotating speed of the motor, the charging time of the capacitor C4 is prolonged, the trigger angle of the silicon controlled rectifier is moved backwards, the voltage of one capacitor terminal or the other capacitor terminal entering 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 regulating 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 formed by a resistor R1 and a capacitor C2 of the speed regulation control circuit is used for absorbing instantaneous spike voltage and preventing the damage of the bidirectional thyristor during overvoltage. Through the action of the speed regulation control circuit, the motor rotation speed can be regulated, and then the opening or closing of the barrier gate of the security inspection machine entrance guard under a proper speed can be regulated.
Because of having two switch, two electric capacity, the electric capacity damages and leads to the motor unable to work in the security inspection machine work, perhaps the capacity of electric capacity diminishes and causes the security inspection machine work abnormal time, and the staff can switch another electric capacity through switch fast, supplies power for the motor of security inspection machine. When the temperature of the capacitor is too high, the temperature detection circuit sounds through the sounder at the first time to prompt a worker to switch the other capacitor, so that the normal operation of the motor and the security inspection machine is ensured. Meanwhile, the speed regulation of the motor is realized according to the commuting condition of the security inspection machine, and the purpose of saving electric energy is achieved on the premise of meeting the full commuting.
