The dynamic time rotates to the second rotation direction, so that lift car 3 is descending.
For example, when there is elevator malfunction event, rescuer can be according to the position of lift car 3 to the input area of touch screen 11
Inching button 113, up button 111 and descending button 112 in domain 110 carry out touch control, to produce crawl signal, up
Signal and downstream signal.Herein as a example by producing crawl signal and upward signal by touch screen 11, the receiving point of control mainboard 12
After dynamic signal and upward signal, then control motor 7 to be rotated to the first rotation direction with preset rotation speed and default rotation time, make
Lift car 3 is obtained with the up relatively short distance of insopection traveling speed, and then realizes the fine setting to the upward position of lift car 3, rescue
Person is by more than 11 generation upward signal of touch screen, so that it may lift car 3 is up to elevator door position, it was adjusted
Cheng Pingwen, makes lift car 3 be not likely to produce in rescue operations and jolts.
Further, automatic button 114 is additionally provided with input area 110, for generating automatic control signal；Control mainboard
After 12 receive automatic control signal, then lift car 3 is calculated most according to range information and default elevator door position height
Short rescue distance；Wherein, most short rescue distance is the distance of the closest elevator door position of lift car 3；Control mainboard 12
The automatic rotation direction and automatic rotation time of motor 7 are calculated according to most short rescue distance and preset rotation speed；Control mainboard 12
Control motor 7 is rotated with preset rotation speed and automatic rotation time to automatic rotation direction.For example, default in control mainboard 12
Elevator door position height value is Di, and i represents the i-th floor, i >=1 and be integer；D is the bottom of lift car 3 and elevator hoistways bottom
The distance between portion.After control mainboard 12 receives automatic control signal, then pass through | d-Di | and calculate lift car 3 apart from whole
The distance between elevator door position, and obtain the most short rescue distance and most of the closest elevator door position of lift car 3
The height value of nearly elevator door position.Control mainboard 12 judges motor 7 by the height value of nearest elevator door position
Automatic rotation direction, specifically, when the distance of lift car 3 is mutually kept to positive number with nearest elevator door position height value, elevator
Car 3 is located on nearest elevator door position, then judge that the automatic rotation direction of motor 7 need to make lift car 3 descending；Work as elevator
When the distance of car 3 is mutually kept to negative with nearest elevator door position height value, lift car 3 is located at nearest elevator door position
Under, then judge that the automatic rotation direction of motor 7 need to make lift car 3 up；Control mainboard 12 is according to most short rescue distance and in advance
If rotating speed calculates the automatic rotation time of motor 7, and then controls motor 7 with preset rotation speed and automatic rotation time to automatic
Rotation direction is rotated, until lift car 3 reaches nearest elevator door position, the control process of the elevator rescue system is simple,
Elevator rescue efficiency is greatly improved, human cost is saved.
Further, stop button 116 is additionally provided with the input area 110 of touch screen 11, for producing stop signal；
Start button 115, for producing enabling signal；Control mainboard 12 receives stop signal, and controls motor 7 to stop operating；Control
Mainboard processed 12 receives enabling signal, and controls motor 7 to start.Thus, when elevator rescue system works, can be according to actual feelings
Condition is stopped and is started control to its motor 7, improves the security of the operation of motor 7.
Further, touch screen 11 is additionally provided with viewing area 117, and range marker viewing area is provided with the viewing area 117
118th, running status viewing area 119；Touch screen 11 receives the range information that control mainboard 12 sends, and is existed according to the range information
Range marker of the display lift car 3 apart from elevator hoistways bottom in viewing area 117；Touch screen 11 also receives control mainboard 12
The rotation direction and output speed of transmission, and elevator is shown in running status viewing area 119 according to rotation direction and output speed
The traffic direction mark and the speed of service of car 3, can image show position of the lift car in elevator hoistways and rescue
During helping, the ruuning situation of lift car is easy to rescuer to understand rescue situations in time, improves the security of rescue operations.
In specific implementation process, because elevator hoistways bottom is typically provided with safety component or buffer etc., can be to elevator
Shaft bottom produces stop, and then causes that distance measuring sensor 4 produces measuring error, if for example, distance measuring sensor 4 is arranged on
The centre of the bottom of lift car 3, the range information that may result in its measurement is between the bottom of lift car 3 and safety component
Distance, rather than the distance between the bottom of lift car 3 and elevator hoistways bottom.Simultaneously as different type elevator hoistways
The safety component or the position of buffer that bottom is set are different, if distance measuring sensor 4 directly is fixed on into certain class lift car 3
Bottom, may cause it can not be compatible with other kinds of elevator.In order to avoid measuring error and raising elevator rescue system
