Embodiment
The present invention will be further described by reference picture 1- Fig. 3.
As shown in Figure 1：Elevator faults and power failure automatic rescue system, including elevator faults detection means 01 and drag device
Whether 02, elevator faults detection means 01 includes failure inductor, break down or have a power failure for sensing elevator, and transmit signal
To controller 1, drag device 02 includes the traction machine provided with brake, in addition to controller 1, the controller 1 and elevator event
Barrier detection means 01 is connected with drag device 02, and controller 1 is also associated with power transfer device 03, flat bed signal supervisory instrument
04th, safety door latch signal supervisory instrument 05；
Described power transfer device 03 includes rescue power supply, for switching between mains supply and rescue power supply；
Described flat bed signal supervisory instrument 04 includes flat bed signal inductor, for sensing whether car is in flat bed state,
And signal is passed into controller 1；
Safety door latch signal supervisory instrument 05 includes safety door latch and believes inductor, for judging whether safety door latch is normal, and will
Signal passes to controller 1.
Further, described power transfer device 03 also includes power supply signal inductor, for determining mains supply and rescuing
Help whether to switch between power supply and finish.
Further, in addition to door machine device 06, described door machine device 06 includes door electromechanical source and door machine.
Further, in place whether described door machine device 06 also includes the inductor in place that opens the door, opened the door for detecting, and believe
Number it will be passed to controller 1.
Further, drag device 02 also includes braking power, for control brake.
Operation principle：When elevator breaks down or has a power failure, the system detectio to elevator faults or power cut signal are first passed through
Safety door latch believes inductor, judges whether safety door latch loop is normal, then cuts off civil power, and connects rescue power supply, gives flat bed sense
Answer device to export DC24V power supplys, whether lift car is judged in level position by flat bed signal, if lift car is in flat bed position
When putting, export AC220V power supplys and powered to door machine, then give door machine one door open command signal, elevator door is opened and puts people, simultaneously
Detection is opened the door signal in place, system detectio to open the door signal in place when can again switch to civil power mode of operation, wait it is to be repaired, this
System stalls.
If lift car is not in level position, the system can export DC110V power supplys to brake, make lift car
Move slowly at upwards（Car is moved using the weight difference of car and counterweight）, when lift car is moved to level position, this is
System can detect flat bed signal, brake release will be draged by detecting that the flat bed signal system can stop output DC110V power supplys
Draw the traction sheave locking of machine, simultaneity factor can export AC220V power supplys and be powered to door machine, then give door machine one door open command signal,
Elevator door is opened and puts people, while detect the signal in place of opening the door, system detectio to enabling in place signal when can again switch to city
Electrician's operation mode, waits the to be repaired, system stalls.
The features of the present invention is exactly, when elevator breaks down or has a power failure, to coordinate the existing flat bed signal of elevator, main frame（Braking
Device）And driver, door machine, then by the control of the system, so as to realize that elevator faults are not oppressive, lift facility is not damaged
Bad, trapped personnel can safely and fast get rid of poverty, safe escape, shown up without waiting for rescue personnel and implement rescue work again, practicality
It is stronger, no potential safety hazard.
The present invention arises at the historic moment to solve above-mentioned technical problem, detects commercial power interruption or elevator faults（But on condition that：
Safety door latch signal is normal）After automatically engage operation, pacified and car automatic help while sending voice during rescue
Signal designation, and lift car is reached door area and automatic door opening, stranded passenger is released, is completed after rescue, the weight of civil power is waited
Normal operation input after new access or elevator faults are excluded.
The present invention is not oppressive except can reach elevator in mains failure, is even more that can also be played when soft fault occurs in elevator
Not oppressive purpose, integrates the function of power failure emergency flat layer device and the function of elevator faults automatic rescue device, very well
Realize the target of not oppressive elevator.
As shown in Figure 3：Described rescue power supply is DC48V batteries, for being powered for each inductor, and described door is electromechanical
Source be it is converted by the first inverter by rescue power supply, braking power be changed by rescue power supply by the second inverter and
Into.
As shown in Figure 2：A kind of elevator faults and power failure automatic rescue method suitable for above-mentioned automatic rescue system, specifically
Step is as follows successively：
A. failure inductor senses Lift out of order, and delivers a signal to controller 1；
B. signal is passed to safety door latch signal supervisory instrument 05 by controller 1, and safety door is judged by safety door latch letter inductor
Whether lock is normal, and signal is passed into controller 1；
C. such as safety door latch determination normally, signal is passed to power transfer device 03 by controller 1, cuts off mains supply, and even
Logical rescue power supply；
D. rescue power supply exports DC24V power supplys to flat bed inductor, and signal is passed to controller 1 by flat bed signal inductor, leads to
Whether cross flat bed signal judges lift car in level position；
If e. lift car is in level position, controller 1 makes an electromechanical source export AC220V power supplys to power to door machine, then
Give door machine one door open command signal, elevator door is opened and puts people, inductor detection in place of opening the door has been opened the door in place, and signal will
Pass to controller 1.
F. signal is passed to power transfer device 03, cut-out connection rescue power supply by controller 1, and connects mains supply.
Further, in step e, if lift car is not in level position, controller 1 makes braking power export DC110V
Power supply makes lift car move slowly at upwards to brake, when lift car is moved to level position, flat bed signal inductor
Flat bed signal is detected, and signal is passed into controller 1, controller 1, which can stop braking power output DC110V power supplys, makes system
Dynamic device release powers the traction sheave locking of traction machine while controller 1 makes an electromechanical source export AC220V power supplys to door machine, then
Give door machine one door open command signal, elevator door is opened and puts people, inductor detection in place of opening the door has been opened the door in place, and signal will
Pass to controller 1.
