Figure.
Fig. 4 A are to schematically show the situation about normally stopping in passenger conveyor system 100 according to the utility model embodiment
Under, the timing diagram of the state of the first relay and the second relay in Fig. 3 and the power supply state of band-type brake circuit 236.
Specifically, as shown in Figure 4 A, started power up in T0 moment, passenger conveyor system 100.AC power VAC startups pair
The power supply of passenger conveyor system 100, the second coil K2 of the second relay obtained at the T0 moment it is electric, so as to control stationary contact 3 and
Two movable contacts 7 close.
At the T1 moment, passenger conveyor system 100 starts, and the master controller 140 of passenger conveyor system 100 controls at the T1 moment
Control signal CTR is high level, so as to which the first coil K1 of the first relay obtains electric, the first normally opened contact of control at the T1 moment
K1-1 closures, the second normally opened contact K1-2 closures and the first normally-closed contact K1-3 disconnect.As can be seen from Fig. 3, due to first after
First normally-closed contact K1-3 of electrical equipment is begun breaking from T1 (the i.e. passenger conveyor system 100 starts) moment, therefore, power circuit
232 are powered by the first normally opened contact K1-1 of first switch S1, the first relay to band-type brake circuit 236.In band-type brake circuit 236
Brake block 239 be in releasing orientation, control band-type brake is opened, so as to the normal operation of passenger conveyor system 100.
At the T2 moment, passenger conveyor system 100 normally stops, and now, power supply normally provides electricity to passenger conveyor system 100
Source.Master controller 140 controls main breaking zone device 120 to brake passenger conveyor system 100 (for example, stopping transfer passage at the T2 moment
110) so that passenger conveyor system 100 stops conveying passenger at the T2 moment.The master controller 140 of passenger conveyor system 100 is from T2
After moment begins to pass through predetermined delay t1 (for example, 3s), control signal CTR is changed into low level, the first relay at the T3 moment
The first coil K1 of device is according to having low level control signal CTR dead electricity, so as to disconnect the first normally opened contact K1-1 and
Two normally opened contact K1-2, and close the first normally-closed contact K1-3.Because the second coil K2 of the second relay both ends connect respectively
AC power VAC is met, in the case where AC power VAC is not interrupted, the second coil K2 is still within obtaining electricity condition, therefore,
The movable contact 7 of stationary contact 3 and second of conversion hysteria contact still closes.
Thus, since the T3 moment, because the second normally opened contact K1-2 disconnects, power supply sub-circuit 233 no longer receives direct current
Power vd C, and because the first normally opened contact K1-1 disconnects, the movable contact 5 of stationary contact 3 and first of conversion hysteria contact disconnects, institute
Power supply to band-type brake circuit 236 is stopped since the T3 moment with, power circuit 232, the brake block 239 in band-type brake circuit is in
Holding state, control band-type brake closure, to pin the transfer passage 110 of passenger conveyor system 100.
In addition, since the T3 moment, due to the movable contact 7 of stationary contact 3 and second of conversion hysteria contact close and first after
Electrical equipment the first normally-closed contact K1-3 closure, so, as shown in figure 3, electric capacity C1 by first switch S1, conversion hysteria contact it is quiet
The loop electric discharge of the movable contact 7 of contact 3 and second, the first normally-closed contact K1-3 of the first relay and resistance R1 compositions.Favorably
, by electric discharges of the electric capacity C1 in discharge loop, the electricity on electric capacity C1 can be discharged as early as possible, it is defeated so as to which passenger can be accelerated
Send the restarting procedure next time of system 100.
It should be understood that the t1 in Fig. 4 A is the predetermined delay that master controller 140 is set, can be according to practical application
Demand, delay t1 is arranged to any desired value, to ensure normally to stop the situation of conveying passenger in passenger conveyor system 100
Under, after the complete stop (coming to a complete stop) of transfer passage 110 of passenger conveyor system 100, complemental brake system 330 pins transfer passage
110, to avoid the impact to passenger, cause unnecessary tumble.
Fig. 4 B are to schematically show to run into emergency in passenger conveyor system 100 according to the utility model embodiment
When, the timing diagram of the state of the first relay and the second relay in Fig. 3 and the power supply state of band-type brake circuit 236.
Specifically, as shown in Figure 4 B, started power up in T0 moment, passenger conveyor system 100.Second line of the second relay
Circle K2 obtained at the T0 moment it is electric, so as to control the movable contact 7 of stationary contact 3 and second to close.
At the T1 moment, passenger conveyor system 100 starts, and master controller 140 controls control signal CTR at the T1 moment as high electricity
It is flat, so as to the first coil K1 of, the first relay obtained at the T1 moment it is electric, it is the first normally opened contact K1-1 of control closures, second normally opened
Contact K1-2 is closed and the first normally-closed contact K1-3 disconnects.Thus, power circuit 232 passes through first switch S1, the first relay
First normally opened contact K1-1 of device powers to band-type brake circuit 236.Brake block 239 in band-type brake circuit 236 is in releasing orientation, control
Band-type brake processed is opened, so as to the normal operation of passenger conveyor system 100.
At the T4 moment, passenger conveyor system 100 runs into emergency, for example, passenger conveyor system 100 exceed the speed limit, reverse or
The drive chain fracture of person's passenger conveyor system 100, in this case, although power supply is not stopped power supply, master controller
140 will control control signal CTR to be changed into low level by the working condition of detecting system 100.Preferably, once system runs into
Emergency, control signal CTR immediately becomes low level under the control of master controller, and (as shown in Figure 4 B, control signal CTR exists
The T4 moment for running into emergency is changed into low level).Thus, first coil K1 dead electricity, the first normally opened contact K1-1 and the is controlled
Two normally opened contact K1-2 disconnect, and the first normally-closed contact K1-3 of control closes since the T4 moment.Due to the second relay
Second coil K2 both ends connect AC power VAC respectively, in the case where AC power VAC is not interrupted, the second coil K2
Electricity condition is still within obtaining, therefore, the movable contact 7 of stationary contact 3 and second of conversion hysteria contact closes.
Thus, since the T4 moment, power circuit 232 stops the power supply to band-type brake circuit 236, in band-type brake circuit 236
Brake block 239 is in holding state, control band-type brake closure, to brake and pin transfer passage 110.Due in T4 moment, master control
Device 140 processed controls main breaking zone device 120 to brake passenger conveyor system 100 (for example, stopping the conveying of transfer passage 110), therefore,
At the T4 moment, braked by complemental brake system 330 and pin transfer passage 110 and may insure to run into tightly in passenger conveyor system 100
During anxious situation, complemental brake system 330 can timely and effectively realize auxiliary braking and the protection to passenger conveyor system 100,
Avoid the brake force of main breaking zone device 120 deficiency or cause the safety of the brake fade of main breaking zone device 120 hidden because drive chain disconnects
Suffer from.
Since the T4 moment, because the movable contact 7 of stationary contact 3 and second of conversion hysteria contact closes and the first relay
First normally-closed contact K1-3 is closed, so, as shown in figure 3, electric capacity C1 passes through first switch S1, the stationary contact 3 of conversion hysteria contact
With the loop electric discharge of the second movable contact 7, the first normally-closed contact K1-3 of the first relay and resistance R1 composition.Advantageously,
By electric discharges of the electric capacity C1 in discharge loop, the electricity on electric capacity is discharged as early as possible, can accelerate the next of passenger conveyor system 100
Secondary restarting procedure.
Fig. 4 C are to schematically show the power outage in passenger conveyor system 100 according to the utility model embodiment
In the case of, the sequential of the state of the first relay and the second relay in Fig. 3 and the power supply state of band-type brake circuit 236
