Abstract
A high-safety automatic wrecking apparatus for different types of elevators features that its position sensor and failure diagnosis device can transmit the failure information to program controlled central assemblage to cut off electric power and start said wrecking apparatus for evacuating the passengers when the elevator fails due to electric interruption or trip, short circuit, or poor electric contact.
Description
The present invention is applicable to all kinds elevator.When elevator has a power failure, the control housing tripping operation, transformer fault during faults such as electric elements bad contact, causes elevator to rest between two floors.Apparatus of the present invention can start elevator automatically, drag elevator and are parked in the floor doorway, and open elevator door automatically, and stranded passenger safety is walked out.
Apparatus of the present invention do not need external power and artificial the intervention, and used power supply is by all storage batteries supplies at any time of this device.
Apparatus of the present invention are by position transduser, the information diagnosis system that the trouble diagnosing device is formed, information diagnosis and the disposal system formed by IC Center's programming control assembly and memory device, by power amplifier, power control system and propulsion source and the actuating system formed of storage batteries automatically, by the loud speaker that can regulate and the warning of wireless transmission, form a full automaticity and detect, the elevator car safety of global procedures control.
Apparatus of the present invention utilize integrated circuit to motor power supply implementation frequency scanning, to determine only frequency, produce the strongest and the most stable electric current.
Best effort dot frequency and current parameters deposit in the memory device, and compare with received data, carry out track-while-scan, obtain the most stable maximum electric current up to motor, and this is that artificial adjustment can't be compared.
When the inside of apparatus for controlling elevator or external power supply et out of order, being installed in elevator tip position sensor obtains for information about, elevator location on the capstan winch, fault detector is connected a contactless contactor, make central program control assembly begin following operating sequence from two information of position transduser and trouble diagnosing device this moment;
--open elevator brake, guarantee the control isolated from power of former power supply of elevator and safety device;
--pass to power supply to controller, pin motor;
--start the central program assembly.
When fault takes place, elevator is between two floors, then the central program control assembly is searched for the parameter of electric machine control best operating point and power controller control in memory device, at this moment acquisition the most stable maximum electric current drags elevator and is parked in the floor doorway from storage battery and power amplifier, and open elevator door automatically, stranded passenger safety is walked out.
Storage battery supply power amplifier, power controller, motor, drg, elevator door motor, the power supply that alarm communication system etc. use.Storage battery keeps charge condition just often.
The present invention also can be used on the hydraulic type elevator, and the electrically operated valve power supply of this unit feeding motor starts elevator when fault takes place, and drags elevator and is parked in the floor doorway.
For the system that further specifies this invention forms and each component function,, its System Operation process is described referring to the system block diagram of Fig. 1.
Among Fig. 1
The 1-motor; The 2-storage battery; 3-central program control assembly; The 4-memory device; The 5-failure detector; The 6-power amplifier; The 7-position transduser; 8-power-adjustable control panel; The 9-power controller; The 10-bat.chgr.; The 11-voice actuated device; The 12-loud speaker; The 13-alarm sending equipment; 14-alarm receptor; 15-projector probe; 16-receptor probe.
When the signal of elevator position sensor 7, the power supply of power-adjustable control panel 8 and storage battery 2 inputs to failure detector 5, starts central program control assembly 3, best operating point parameter in the searching storage 4.Failure detector 5 is connected loud speaker 12 and is reported to the police, by alarm sending equipment 13 and alarm receptor 14 receiving alarm signals through voice actuated device 11 during if any fault.Meanwhile central program control assembly 3 is isolated former control system, connects the power amplifier 6 of power controller 9 controls, automatically elevator is started, and drags elevator and is parked in the floor doorway, and open elevator door automatically, and stranded passenger safety is walked out.
This apparatus features is to be applicable to all kinds elevator, and no matter the elevator dragging motor is an alternating current dynamo, and DC machine still is the hydraulic type elevator.
Another characteristics of this device are searched for the motor best operating point automatically for the motor employing micro controller system of various elevators, determine optimal frequency, so that obtain maximum and the most stable electric current from storage battery.

--open elevator brake, guarantee the control isolated from power of former power supply of elevator and safety device;
--pass to power supply to controller, pin motor;
--start the central program assembly.
Central control unit is realized following purpose;
--frequency scanning is carried out in power supply to motor, to determine only frequency, produces the strongest and the most stable electric current, so that power when Lift out of order.
--according to the data that the scanning to the strongest and steady current calculates, the best operating point of storage motor.
This safety device can be sought best operating point, is that following elements plays an important role in the central program control assembly;
--to motor, drg, the inverter of elevator door motor and the power supply of other parts, the effect of inverter is that direct current (DC) is become alternating current.
--the memory device of storage computation value.
3, as claim 1 and 2 described elevator car safeties, it is characterized in that information diagnosis system is made up of position transduser and trouble diagnosing device.When Lift out of order, as having a power failure the circuit for controlling motor tripping operation, transformer short-circuit, contactless switch bad contact etc., and elevator is parked between two floors, this moment, position transduser sent the elevator position signal, and the trouble diagnosing device sends ct-off signal, and two paths of signals is passed to central control unit simultaneously, send alerting signal, cut off the former control power supply of motor, start this control setup, drag elevator automatically and be parked in nearest floor, and open elevator door, allow passenger safety walk out.
