When entering detection unit 24 and detecting predetermined failure, control first switch 16 postpones third preset time t3Shutdown, control second are opened
Close 22 the 4th preset time ts of delay4Shutdown.In this way, can in 50 operational process of band-type brake coil, as long as external control signal without
When imitating or predetermined failure occur, first switch 16 and second switch 22 are turned off step by step, to the safely and reliably total power supply of shutdown
Power supply of the source 30 to band-type brake coil 50.The process of shutdown control is reliable and stable and noise is relatively low.
Wherein, third preset time t3, the specific part category or control that can usually be selected according to first switch 16 are patrolled
That collects select.4th preset time t4, generally also can according to second switch 22 select specific part category or
Control logic select.
Control unit 12 is after first switch 16 and 22 the last time of second switch are turned off, if band-type brake signal element 40 is defeated
The external control signal that goes out is effectively and predetermined failure is not detected in output detection unit 18 or input detection unit 24, then controls the
Two switches 22 postpone the 5th preset time t5Conducting, control first switch 16 postpone the second preset time t2Conducting.In this way, can be with
Effectively and after predetermined failure elimination, restore first switch 16 step by step in external control signal automatically and second switch 22 is connected, make
Band-type brake coil 50, which is powered, to be run.Automatically the control efficiency resumed operation is high, and control process is steadily reliable.
Wherein, the 5th preset time t5The specific part category or control that can be generally also selected according to second switch 22 are patrolled
That collects select.
The external control signal of 40 output of judgement band-type brake signal element in above-described embodiment is effective and exports detection unit
18 or input detection unit 24 when predetermined failure is not detected, control second switch 22 postpones the 5th preset time t5Conducting, control
First switch 16 processed postpones the second preset time t2Can also include following procedure after the process of conducting：
In the state that first switch 16 and second switch 22 are connected, control unit 12 judges that external control signal is invalid
When, such as elevator reaches destination and needs to stop, when clearance passenger, external control signal can stop control with elevator and switch to
Invalid state；When external control signal is invalid, control unit 12 controls first switch 16 and postpones the shutdown of the 6th preset time, at this time
Band-type brake coil 50 is powered off out of service and is braked to the power motor of elevator.
After the shutdown of first switch 16, control unit 12 judges that the external control signal of 40 output of band-type brake signal element is effective
And when second switch 22 is in the conduction state namely external control signal switchs to effectively and occurs without predetermined failure again, control
Unit 12 controls first switch 16 and postpones the conducting of the 7th preset time.In this way, band-type brake coil 50 may be implemented in elevator normal load
Automatically shutting down during passenger traffic row and the recovery control that is powered, control process is reliable and steady, and noise is low, is conducive to improve passenger's
Boarding is experienced.
Wherein, the 6th preset time t6The specific part category or control that can be generally also selected according to first switch 16 are patrolled
That collects select.7th preset time t7The specific part category or control that can also be selected according to first switch 16 are patrolled
That collects select.As long as the setting of the preset time above and in above-described embodiment can realize efficient logic control
Effect.
