Accompanying drawing explanation
Fig. 1 is the circuit block diagram of elevator standby rescue system of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, a kind of elevator standby rescue system, comprises elevator main 1, elevator brake 2, control loop 3, drives loop 4, short circuit contactless switch 5, door zone sensors 6, door machine loop 7 and back-up source 8 that can automatic charging.Back-up source 8 is control loop 3, drives loop 4, elevator brake 2 and door machine loop 7 to power when system starts, drive loop 4 to be connected with the three-phase input end of elevator main 1, short circuit contactless switch 5 is in order to the three-phase input end of short circuit elevator main 1, and maintenance normally off.Control loop 3 detects the signal of the rotary encoder 9 on elevator main 1 and the signal of door zone sensors 6 in real time, and control accordingly and drive loop 4, elevator brake 2 and 7 actions of door machine loop according to detection signal, drive loop 4 by receiving the control signal of control loop 3, the direct current (DC) of back-up source 8 can be converted to alternating current and drive elevator main 1 operation.
Preferably, control loop 3 comprises: for the treatment of the MCU main control chip of signal, detection elevator main operating speed and control elevator operation, for the treatment of the code device signal receiving loop of rotary encoder through signals, and for receiving and control the I/O interface of elevator operating state.
Preferably, drive loop 4 comprise for by DC inverter, be the alternating current IPM module that drives elevator main running, for controlling the gate pole control loop of IPM module work, current sensor for feedback current signal for control loop.
Preferably, control loop 3 is by detecting the operating speed of the rotary encoder through signals acquisition elevator main 1 on elevator main 1, and when its speed surpasses preset value, 2 actions of automatic control electric ladder drg shut down motor main frame 1.
To sum up, the concrete operation steps of elevator standby rescue system of the present invention is as follows:
1) standby rescue system drops into step
Under normal circumstances, back-up source 8 is by civil power automatic charging.When elevator because have a power failure, when control housing internal fault or other line fault, back-up source 8 can receive the corresponding signal of apparatus for controlling elevator and start to the power supply of standby rescue system, elevator is switched to standby rescue state.
2) rescue operation starts step
After standby rescue system puts into operation, the MCU main control chip of control loop 3 detects whether Men district of lift cars by door zone sensors 6: if lift car in Men Qu, directly open the door in driving gate machine loop 7; If lift car in not gate district, is rescued operation and is controlled.
3) rescue operating procedure
MCU main control chip in control loop 3, is opened by I/O interface driver elevator brake 2 in not gate district by door zone sensors 6 confirmation lift cars.Meanwhile, short circuit contactless switch 5 remains the three-phase input of closure state short circuit elevator main 1, and the running state of elevator has two kinds of possible situations and occurs:
If the 1. laod unbalance on Elevator weight sensor and car both sides now, the traction sheave of elevator main 1 will rotate from the heavier side of trend load, make the rotor field of elevator main 1 and stator coil mutually cut generation current.In the loop that electric current becomes at three-phase short circuit, produce and hinder the moment that rotor rotates, this moment will soon and counterweight and car between the poor balance of load, elevator main 1 is traveled at the uniform speed, and now lift car can run to a zone position to be about the speed of 5～6m/min.
If 2. lift car reach state of equilibrium close to counterweight lateral load, elevator main 1 will keep transfixion, control loop 3 receives the rotary encoder through signals on elevator main 1 by code device signal receiving loop, the pulse count obtaining when the computation period fixing is less than certain numerical value, MCU main control chip judgement elevator main is quiescence, and lift car is load balanced state.Under state of equilibrium, the moment that elevator main 1 running will provide in fact only needs to overcome the friction force of physical construction, therefore only needs the very little electric current (being about 5～6A) of input can drive elevator main 1 operation.Now, the MCU main control chip in control loop 3 sends control signal by I/O interface to driving loop 4, and opens short circuit contactless switch 5.Gate pole control loop in driving loop 4, according to the signal of control loop 3, drives the action of IPM module, the direct current (DC) of back-up source 8 is converted to alternating current and is input to elevator main 1.Control loop 3, according to driving the value of feedback of current sensor in loop 4 to carry out closed loop control, with inspection speed running, drives elevator cage operation to door zone position with small current driving elevator main 1.
4) rescue completing steps
When elevator car arrives door zone position, control loop 3 receives the signal of a zone sensors 6, can cut off the power supply of elevator brake 2, controlling elevator brake 2 actions makes elevator main 1 out of service, car Men district stops, control loop 3 is by 7 actions of output enabling signal driving gate machine loop, and rescue trapped personnel opens the door.
As described above, it is only preferred embodiment of the present invention, can not limit scope of the invention process with this, the simple equivalence of in every case doing according to the present patent application the scope of the claims and invention description content changes and modifies, and all still remains within the scope of the patent.
