GND signal is through the J5.7 pin of pin J9.1 (JC1) output to elevator main control board U1, elevator main control board
U1 judges that its J5.7 pin turns on J5.10 pin, and elevator main control board U1 thus judges to learn the first braking
The band-type brake of device is opened.In like manner, elevator main control board U1 judges to learn second brake detection switch SQB2 simultaneously
The band-type brake of second brake is also opened.
When elevator needs brake to close, control brake energy supply control module input interface BK1, BK2
Dead electricity, now the equal dead electricity of coil YB1, YB2 of first, second brake, two arrester closes, hold tightly and drag
Running wheel, thus control car and stop；As a example by the first brake action, the coil YB1 of the first brake breaks
Electricity, first brake detection switch SQB1 reset Guan Bi, arm processor U2 chip judge its 35 pin with
33 pin Guan Bis, arm processor U2 controls its pin 20 and does not export GND signal, the first relay K 1
Coil losing electricity, its first normal opened contact K1-1 disconnects, and pin J9.1 does not export GND signal to elevator master control
The J5.7 pin of plate U1, elevator main control board U1 judges that its J5.7 pin is different from J5.10 pin level,
Learn the first brake Guan Bi.The coil blackout of second brake simultaneously, second brake detection switch
In like manner, elevator main control board U1 judges that its J5.8 pin is different from J5.10 pin level in the action of SQB2,
Know that the band-type brake of second brake also closes.
Common port com and earth terminal GND is a signal in actual applications, in the present embodiment for district
Point, com pin employing " common port com " that this one side brake device test control panel is peripheral, this one side brake
The corresponding pin of device testing and control intralamellar part uses entitled " earth terminal pin GND ".
When needing to test one side brake device:
To allow as a example by the first misfunctioning of brake, when doing one side brake test, by the breakout cable of the first brake
Extract from brake interface J2.1～J2.4 of this one side brake device test control panel, be connected to this accordingly
At fail bit brake interface J4.1～J4.4 of one side brake device test control panel.The most standing power supply inputs
Pin J1.3, J1.4 power to the first brake of fail bit interface, and standing power supply has an electricity always, and now
One brake coil YB1 obtains electric, first brake detection switch SQB1 action disconnect, pin J4.3 with connect
Pin J4.4 disconnects, and arm processor U2 receives the change of its pin 31,33, thus judges the first brake
Open, now, in the case of brake energy supply control module input interface two pin J1.1, J1.2 power,
It is connected to the second brake energized action of two brake interfaces, after arm processor U2 processes, at ARM
The pin 20,21 of reason device U2 exports GND signal simultaneously, and first, second relay K 1, the coil of K2 obtain

Signal, can run elevator, now, make the environment of the first misfunctioning of brake meet when one-sided test,
The experiment of the one-sided test to second brake can be carried out.One-sided test experiment to second brake is existing skill
Art, repeats no more here.
When one-sided test, the first brake on fail bit interface always electric, the band-type brake of the first brake
Losing efficacy, and unclamped traction sheave, the first brake detection switch SQB1 disconnects always.It is positioned at two brake interfaces
Second brake do not lost efficacy, pin J3.3, J3.4 of two brake interfaces monitor second brake in real time
The state of detection switch, arm processor U2 is by the monitoring to its pin 32,33, it is thus achieved that the second braking
The state of device.When the one-sided test of second brake being completed (i.e. this one side brake device test control panel detection
One all after date of second brake action), the 22 pin output GND signals of arm processor U2, the 3rd continues
The coil of electrical equipment K3 obtains electric, its first normal opened contact K3-1 adhesive, this one side brake device test control panel
J9.3 pin turns on earth terminal GND, the fault of J9.3 pin output GND signal to elevator main control board U1
Signal input part J5.9 pin, elevator main control board U1 can point out operating personnel by the first brake from inefficacy
Position interface is reset to a brake interface, after the first brake is reset to a brake interface, and the first system
Dynamic device detection switch SQB1 resets and closes, and the J2.3 pin of a brake interface turns on J2.4 pin,
Arm processor U2 judges its 33 pin, the level of 35 pins, it is judged that show that the first brake is reset to
One brake interface, arm processor U2 controls its 22 pin and recalls fault-signal, the most do not exports GND
Signal, elevator main control board U1 judges the level change of its J5.9 pin, learns and cancel fault-signal, this
First misfunctioning of brake, the one-sided test that carries out second brake are terminated.
As the first brake is carried out one-sided test, it is from two brakes by the breakout cable of second brake
Interface takes out, and is connected to fail bit brake interface, the first brake can be carried out one-sided test, test
Process in like manner, repeats no more here.
