Feedback and early warning, can only repair and replacement afterwards, be that user has carried inconvenience.
Content of the invention
In order to solve above-mentioned technical problem, the present invention proposes a kind of electromagnetic lock and its control circuit.It can effectively overcome
The problem that the solenoid leading to because electromagnetic lock maintains unlocking condition for a long time burns, thus play a protective role.
To achieve these goals, the technical scheme is that
A kind of electromagnetism lock control circuit, including drive circuit, also includes:
Monostable circuit, is connected with described drive circuit, monostable circuit is used for:
In response to redirecting as effective external control signal, output high level from invalid；Or
In response to keeping effectively described external control signal, export low-voltage；
Drive circuit is used for:
Receive the high level of described monostable circuit output, drive electromagnetic lock actuator work to realize unlocking；Or
Receive the low level of described monostable circuit output, the work stopping electromagnetic lock actuator keeps unlocking condition.
Described monostable circuit includes electric capacity, first resistor and second resistance, and described electric capacity connects institute by first resistor
State drive circuit, the junction between described electric capacity and described first resistor is grounded by described second resistance, described electric capacity is used
In the described external control signal of reception.
Described drive circuit includes audion and mos switching tube, and the base stage of described audion connects described monostable circuit
Outfan, described mos switching tube connects described electromagnetic lock actuator, and described audion is defeated according to described monostable circuit
Go out signal, drag down the grid of mos switch or the grid drawing high mos switching tube, lead through and off with control described mos switching tube
Open.
Also include Zener diode, positioned at the outfan of described drive circuit, for stablizing the output of described drive circuit
Voltage.
Second aspect, the application provides a kind of electromagnetic lock, and described electromagnetic lock includes described electromagnetism lock control circuit.
The invention has the beneficial effects as follows: electromagnetism lock control circuit passes through using in response to redirecting as effectively outside from invalid
Control signal simultaneously exports high level, or in response to keeping effectively described external control signal export the monostable of low-voltage
Circuit, and the high level driving electromagnetic lock actuator work realization unlocking of reception described monostable circuit output, or receive
The low level of described monostable circuit output stops the drive circuit of the work holding unlocking condition of electromagnetic lock actuator, effectively
Solve the problems, such as that electromagnetic lock keeps the solenoid that brings during driving condition to destroy for a long time, extend the use of electromagnetic lock
In the life-span, avoid conduction time on the electromagnetic lock leading to due to reasons such as software crash long and lead to solenoid to burn out simultaneously
The problems such as electromagnetic lock.
Brief description
Fig. 1 shows the circuit diagram of the electromagnetism lock control circuit according to embodiments herein.
Specific embodiment
In order to be better understood by technical scheme, 1 the invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of electromagnetism lock control circuit, including monostable circuit and drive circuit；Monostable circuit connects
Drive circuit.Monostable circuit is used for:
In response to redirecting as effective external control signal, output high level from invalid；Or
In response to keeping effective external control signal, export low-voltage.
Monostable circuit includes electric capacity c19, first resistor r51 and second resistance r53, and electric capacity c19 is used for receiving outside control
Signal processed, electric capacity c19 connects drive circuit by first resistor r51, and the node between electric capacity c19 and first resistor r51 passes through
Second resistance r53 is grounded.
Drive circuit is used for:
Receive the high level of monostable circuit output, drive electromagnetic lock actuator work to realize unlocking；Or
Receive the low level of monostable circuit output, the work stopping electromagnetic lock actuator keeps unlocking condition.
Electromagnetic lock actuator includes relay rl1 and connected unlocking mechanism.
Drive circuit includes audion q10, mos switching tube q9, resistance r52 and resistance r54, above-mentioned first resistor r51
The base stage of connecting triode q10, the grounded emitter of audion q10, the colelctor electrode of audion connects mos by resistance r52 and opens
Close the grid of pipe q9, the source electrode of mos switching tube q9 connects voltage source, is provided with resistance between the source electrode of mos switching tube q9 and grid
The drain electrode of r54, mos switching tube q9 connects the 1st pin of relay rl1, the 2nd pin ground connection of relay rl1, relay rl1
The 3rd pin be connected unlocking mechanism with the 4th pin.
Drive circuit also includes stabilivolt d5, and stabilivolt d5 is connected between mos switching tube q9 drain electrode and ground, stable output
Voltage to relay rl1.
A kind of electromagnetism lock control circuit, its work process is:
Ctrl_sig signal is the control signal from main frame or slave computer, when this control signal redirects from low level " 0 "
During for high level ' 1 ', expression will be unlocked.Lock_drv signal is power supply, controls mos switching tube q9 Switching Power Supply by audion q10.
The trigger of monostable circuit triggers for rising edge, and that is, level touches when low level redirects to high level
Send out.Specific work process is: when ctrl_sig signal is that is, level redirects to high level from low level when ' 0 ' changes to ' 1 '
