The power supply of integrating circuit, after electrical switch is opened, power supply is powered to integrating circuit；Electrical switch is handed in the presence of alternating signal
For being on, closed mode, the voltage signal of power supply is modulated into alternate level signal by alternating signal；Integrating circuit is to alternation
Level signal is integrated computing, exports high level signal, high level turn-on transistor q19, and then maintains boot-strap circuit conducting.
As shown in figure 1, including current-limiting resistance r11 and the electric capacity c12 being connected with current-limiting resistance r11 every straight module；Electronics
Switch includes pulling up biasing resistor r8, audion q2, stagnant electric discharge resistance r9；Integrating circuit includes electric capacity c9.Current-limiting resistance r11 with micro-
Controller mcu connects, and electric capacity c12 is connected with the base stage of pull-up biasing resistor r8, audion q2, pull-up biasing resistor r8, three poles

Work process of the present invention:
During start, when pressing lock off switch sw6, resistance r13 is made to be grounded by opposed diodes u2, with resistance r14
Form partial pressure, thus the gs end (between source electrode and grid) of mos pipe q14 forms voltage, make ds two ends (drain electrode and the source of mos pipe q14
Interpolar) turn on, power_in exports power_out, and meanwhile, microcontroller mcu samples key_adj signal by r15, from
When Fig. 1 can be seen that power_out for high level, key_adj signal is also high level, and microcontroller mcu receives high level
Signal, exports alternating signal by mcu_closed.Based on the characteristic unclamped after the pressing of lock off switch, hereafter, start
Circuit cannot pass through lock off switch conduction, needs to rely on delay control circuit to maintain conducting state.Resistance r11 is current limliting electricity
Resistance, because electric capacity has a characteristic of " separated by direct communication ", the signal of non-alternating cannot be by being made up of resistance r11 and electric capacity c12
Every straight module, and alternating signal source could be passed through, and therefore microcontroller mcu only has the upset exporting a characteristic frequency and dutycycle
Level signal (there are low level and two voltages of high level in trigging signal signal, can be 0 and supply voltage, or therebetween
Numerical value), electric capacity c12 just turns on, and so, the mode of output order is changed into trigging signal output (upset electricity from constant level output
Putting down is one kind of alternating signal), reduce the possibility of misoperation, constant level cannot be passed through.After the conducting of straight module, power supply
By pulling up biasing resistor r8, power_out ensures that audion q2 has conduction voltage drop, q2 base stage just has electric current, and q2 is opened,
Electronic switching circuit turns on.Based on alternating signal characteristic, audion q2 is in the state alternately opened, close, power supply power_
The voltage signal of out is modulated into alternate level signal.After electronic switching circuit conducting, power supply power_out enters to electric capacity c9
Row charges, and integrating circuit is integrated computing to alternation (upset) level signal, so that control end is exported and maintains high level,
This high level makes audion q19 turn on, and audion q19, in the case that lock off switch sw6 does not press, makes mos pipe q14
Gs end formed voltage, mos pipe q14 ds two ends conducting, power_in export power_out reach time delay start mesh
's.In this process, export alternating signal to delay control circuit without microcontroller mcu, then mos pipe q14 cannot
Conducting, start is interrupted, and does not reach start effect.
During shutdown, to shutdown after start, discharge after pressing lock off switch sw6 button again, now, key_adj
Signal was detected the presence of low level signal by microcontroller mcu and triggered, then, microcontroller mcu can be made a reservation for automatic time delay one
Time or after confirming the cut-out of industrial computer process, then stop exporting alternating signal, as it was previously stated, not having alternating signal to export to prolonging
When control circuit in the case of, mos pipe q14 cannot turn on, and power_in can not export power_out, thus reaching shutdown
Purpose.
