Abstract
The utility model discloses an elevator leveling shaft information system which comprises a camera (1) arranged on the top of a shaft and a re-leveling position sensor (5). The camera (1) is connected with an elevator host (4) through an A/D conversion chip (2) and a microcontroller (3) in sequence, and the re-leveling position sensor (5) is connected with a tractor (8) through the microcontroller (3), a shunt release (6) and a breaker (7) in sequence. The camera is used for shooting the environment of the shaft in real time, the microcontroller is used for analyzing captured information, when information is abnormal, signals are sent to the elevator host, and the elevator host controls a lift car to level at the closest floor in the operation direction. In addition, when the lift car accidentally moves, the shunt release is activated, the breaker on the tractor is turned off, and shear accidents of the elevator due to accident moving of the lift car are avoided.
Description
Technical field
The utility model relates to a kind of Elevator landing hoistway information system, belongs to elevator industry technical field.
Background technology
Along with the development of national economy society, elevator is widely used in various buildings.But elevator safety problem is taken elevator to people and is impacted.
If the hoistway environment of elevator occurs abnormal, can cause boarding accident.Yet existing elevator is not equipped with and can carries out the relevant information monitored control system of effective monitoring to hoistway environment, has potential safety hazard.In addition; existing lift car is under door opening state, and the single component failure of the drive system that can rely on due to the operation of elevator main or car safety causes accidental movement, makes car leave flat bed region again; very easily cause and shear injury, elevator need be protected immediately.
Utility model content
The purpose of this utility model is, a kind of Elevator landing hoistway information system is provided.The utility model not only can carry out effective monitoring to hoistway environment, but also has advantages of and can detect car accidental movement, has avoided the shearing accident occurring because of accidental movement of elevator cage.
The technical solution of the utility model: a kind of Elevator landing hoistway information system, comprise the camera that is arranged on well headroom, camera is connected with elevator main through A/D conversion chip, microcontroller successively; Also comprise level position sensor again, then level position sensor is connected with towing machine through microcontroller, shunt release, circuit breaker successively.
In aforesaid Elevator landing hoistway information system, described A/D conversion chip is ADC0809 chip.
In aforesaid Elevator landing hoistway information system, described microcontroller is AT89C52 micro controller system.
Compared with prior art, the utility model is taken hoistway environment in real time by camera, and utilizes microcontroller to analyze the information photographing, and in information, exists when abnormal, send a signal to elevator main, by elevator main, control the nearest floor flat bed of car on service direction; In addition, the utility model meets accident when mobile at lift car, activates shunt release, disconnects the circuit breaker of traction pusher side, the shearing accident of having avoided elevator to occur because of accidental movement of elevator cage.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Being labeled as in accompanying drawing: 1-camera, 2-A/D conversion chip, 3-microcontroller, 4-elevator main, 5-is level position sensor again, 6-shunt release, 7-circuit breaker, 8-towing machine.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.An Elevator landing hoistway information system, as shown in Figure 1, comprises the camera 1 that is arranged on well headroom, and camera 1 is connected with elevator main 4 through A/D conversion chip 2, microcontroller 3 successively; Also comprise level position sensor 5 again, then level position sensor 5 is connected with towing machine 8 through microcontroller 3, shunt release 6, circuit breaker 7 successively.
As preferably, described A/D conversion chip 2 is ADC0809 chip.
As preferably, described microcontroller 3 is AT89C52 micro controller system.
Principle of work of the present utility model:
(1) 1 pair of hoistway environment of camera is taken in real time, and after being changed into digital signal by A/D conversion chip 2, the video information photographing sends microcontroller 3 to, microcontroller 3 is made comparisons the hoistway environmental information receiving and normal hoistway environmental information, if both are inconsistent, send a signal to elevator main 4, by elevator main 4, control the nearest floor flat bed of car on service direction;
(2) microcontroller 3 is according to the output signal of level position sensor 5 again, judge lift car whether meet accident mobile (accidental movement refers to that lift car has left flat bed region again), if, by activating shunt release 6 cut-off breakers 7, towing machine 8 can not be started, and elevator can not move.
Claims (3)
1. an Elevator landing hoistway information system, is characterized in that: comprise the camera (1) that is arranged on well headroom, camera (1) is connected with elevator main (4) through A/D conversion chip (2), microcontroller (3) successively; Also comprise again level position sensor (5), then level position sensor (5) is connected with towing machine (8) through microcontroller (3), shunt release (6), circuit breaker (7) successively.
2. Elevator landing hoistway information system according to claim 1, is characterized in that: described A/D conversion chip (2) is ADC0809 chip.
