Abstract
The utility model discloses a kind of controllable scram button, and a kind of controllable scram button adds an external control circuit that can be realized to scram button on-off function on the basis of original scram button.The utility model has the advantage of：After the work of electric control system controlled components normal power-up, if scram button occurs malfunctioning or by after false triggering, controlled components are unaffected, so as to continue normal work, controlled components power off after field personnel needs in scram button triggered as normal really, touch-switch only need to be pressed, the outside control function of scram button is closed.So not only ensure the normal production work of system, and the economic loss much brought due to maloperation can be reduced.
Description
Technical field
It the utility model is related to a kind of scram button, especially a kind of scram button by outside control.
Background technology
Scram button is an indispensable part in many application scenarios for needing emergency shutdown, but we are common
Scram button does not have outside control function, as long as after being pressed, the system power-off that will pull up a horse is stopped, but very
More occasions are as escalator, if midway is pressed unintentionally by child or adult, staircase immediately powers off out of service, and having very much can
It can cause the generation of accident.
The content of the invention
The purpose of this utility model is to provide a kind of controllable scram button, on the basis of common scram button, increases
An external control circuit that can be realized to scram button on-off function is added, can have been controlled, reduced by the switch of outside
The loss brought due to the false triggering or malfunction of scram button and serious consequence.
The technical solution of the utility model is：On the basis of common scram button, a control scram button is added
The external circuit of break-make.
The controllable scram button includes button S, model XB2BS542C；Double D trigger, model CD4013；Resistance
R1, R2, R3, the common fixed carbon resister of model；Electric capacity C1, C2, model electrochemical capacitor；Sustained diode, model
IN5350；Triode Q, model D882；Touch-switch Key, the common microswitch of model；Electromagnetic relay K, model
SDR-12VDC-SL-C；Double D trigger CD4013 the 1st pin is connected to the 11st pin, and is connected to the 4th by resistance R1
Pin, the 3rd pin is connected to DC12V positive sources by electric capacity C1, and is connected to DC12V power cathodes by resistance R2,
One end of touch-switch is connected to simultaneously, and the other end of touch-switch is connected to DC12V positive sources, and the 4th pin passes through electric capacity
C2 is connected to the 6th pin, and the 6th pin, the 7th pin, the 8th pin, the 10th pin and triode Q emitter stage are connected to DC12V
Power cathode, the 9th pin are connected to the 12nd pin, and the 13rd pin is connected to triode Q base stage, the 14th pin by resistance R3
DC12V positive sources are connected to, and are connected with the negative pole of electromagnetic relay K one end and afterflow triode Q, electromagnetism relay
The device K other end is connected with the colelctor electrode of the positive pole of sustained diode and triode Q, one end of the normally closed points of electromagnetic relay K
B1 is connected with one end a1 of button S normally-closed contacts, other end b2 and the button S normally-closed contacts of electromagnetic relay K normally closed point
Other end a2 is connected.
The utility model has the advantage of：After the work of electric control system controlled components normal power-up, if jerk is pressed
Malfunctioning occurs in button or by after false triggering, controlled components are unaffected, so as to continue normal work, as work on the spot people
Member needs the controlled components after scram button triggered as normal to power off really, only touch-switch need to be pressed, by the outside of scram button
Control function is closed.So not only ensure the normal production work of system, and can reduce and much be brought due to maloperation
Economic loss.
Brief description of the drawings
Fig. 1 is the utility model circuit connection diagram.
Embodiment
Controlled components one end of electric control system is connected to power supply B, and one end is connected to electricity by controllable scram button
Source A, power supply A, B both ends incoming transport power supply.For system normally after upper electricity, double D trigger CD4013 the 13rd pin is low level,
Triode Q is not turned on, therefore electromagnetic relay K coils both ends no power, and electromagnetic relay K is failure to actuate, so electromagnetic relay
Normally closed both ends b1 and b2 still turn on, if now scram button is triggered, although scram button S normally-closed contact both ends a1
Disconnected with a2, but because a1 is connected with b1, a2 is connected with b2, and b1 turns on b2, so a1 and a2 both ends still turn on, because
This controlled components continues normally to work on power, and not being triggered by scram button is influenceed.
Pressing touch-switch Key, double D trigger CD4013 the 13rd pin is high level by low transition, three
Pole pipe Q is turned on, and electromagnetic relay K coils both ends are powered, and electromagnetic relay action, normally closed both ends b1 and b2 disconnect, if now
Scram button is triggered, and scram button normally-closed contact both ends a1 and a2 disconnect, and controlled components power-off of pulling up a horse is stopped.
Press touch-switch Key again, double D trigger CD4013 the 13rd pin is low electricity by high level saltus step
Flat, electromagnetic relay is failure to actuate, and normally closed both ends b1 turns on b2, therefore no matter whether scram button is triggered, scram button
Normally-closed contact both ends a1 and a2 all turn on, so controlled components will continue normal work, do not influenceed by scram button triggering.
