Abstract
A kind of hoistway door detection warning system, the hoistway door including the hoistway door position being arranged on every layer detects alarm device, is arranged on the floor signal retransmission unit near elevator；This hoistway door detection warning system need not every floor again and all installs lift car infrared ray sensor, can realize detecting warning function, reduce the construction cost of elevator monitoring system；Meanwhile, the floor information that lift car is presently in is obtained by elevator black box, will not be affected by the control system of elevator self, so ensureing that Intelligent warning system for abnormal opening of hoistway door testing result standard is cut.The present invention also provides for a kind of hoistway door detection alarm method.
Description
Technical field
The present invention relates to elevator safety monitoring technical field, particularly to a kind of hoistway door detection warning system and side
Method.
Background technology
For the safety protecting elevator to run, need the hall door of gate and each stop is detected, only work as elevator
Gate and after the hall door of all stops all closes, elevator can startup optimization, this is all made by the elevator safety specification of various countries
Strict regulation.Along with the continuous expansion of the economic development of China market and city size, high residential building, hotel, write
Building gets more and more, and the quantity installing elevator also increases sharply, and these elevators offer convenience the people giving the skyscraper that comes in and goes out
There is also potential safety hazard in various degree, have even brings serious injury to life property safety of people simultaneously.According to
The security incident adding up current elevator 60% is all to be made hoistway door abnormal start-up cause personnel to hinder by hall door mechanism-trouble
Die.
Therefore need to carry out safety detection, such as number of patent application for elevator hall's abnormal start-up be
200710038012.3, the Chinese invention of invention entitled " safety detection device of door of elevator waiting hall and detection method thereof " is special
The disclosed technical scheme of profit is: installing a mechanical switch at each stop hall door, this mechanical switch closes door state completely in hall door
Lower Guan Bi, disconnects during enabling；Stop signal processing apparatus reads in machinery switching signal, and is sent by this signal with serial communication mode
Enter electric life controller；Electric life controller obtains car position and the relevant information of elevator the most in real time, and according to the car of elevator
Position and relevant information and the state of each layer hall door mechanical switch, make safe judgement.This invention is capable of detecting when non-elevator car
Though place, railway carriage or compartment layer hall door is opened and lift car at certain layer but can not open the door region and this layer of hall door is opened not at this layer
Security incident, is effectively improved elevator safety performance.
In place of but this invention yet suffers from following some shortcomings: 1, hall door close the door state monitoring apparatus use machinery open
Closing, the reliability and stability of its organization switch are relatively poor；2, this device circuit must be connected with apparatus for controlling elevator,
Could read stop signal and elevator car position signal, this is likely to be due to this device circuit fault and affects elevator controlling system
System, in some instances it may even be possible to cause the generation of elevator faults；3, for the analysis having been made by, this device does not has warning reminding merit
Can, people are difficult to obtain information in time.
For the problems referred to above, prior art gives new technical scheme, such as number of patent application and is
201110035275.5, the China of invention entitled " Intelligent warning system for abnormal opening of hoistway door and safety detection method thereof "
Technical scheme disclosed in application for a patent for invention is: infrared observation technology: use hoistway door infrared ray sensor and elevator car
Railway carriage or compartment infrared ray sensor close to monitoring technology, when closing when hoistway door, hall door infrared ray sensor can monitor elevator
Hall door signal；In like manner, when lift car close to time, car infrared ray sensor can monitor lift car signal.At same Stall
Two infrared ray sensor of layer with the use of, be achieved in that when hall door is opened and judged that whether lift car is at This floor.The Room
The signal of door infrared ray sensor and car infrared ray sensor is read signal, central processing unit i.e. city by central processing unit
The unit machine that field is common, central processing unit carries out logical judgment to hall door signal and the car signal of reading, if hall door occurs different
Normally open, then alarm signal is sent to alarm drive circuit, otherwise waits for the unlatching of hall door next time.At floor address code electricity
Road is preset floor coding identical with the actual floor number of plies, when opening hall door and lift car not at This floor, central processing unit
The floor data in floor address code circuit can be read, and be sent to serial interface circuit and wireless radio transmission circuit
In, to be ready for use on the extension of system.
Above-mentioned Application No. 201110035275.5, invention entitled " Intelligent warning system for abnormal opening of hoistway door and
Its safety detection method " although Chinese invention patent application can solve number of patent application be 200710038012.3, invention
The technical problem that the Chinese invention patent of entitled " safety detection device of door of elevator waiting hall and detection method thereof " exists, but
It is above-mentioned Application No. 201110035275.5, invention entitled " Intelligent warning system for abnormal opening of hoistway door and safety thereof
Detection method " Chinese invention patent application there is problems: every floor all install hoistway door infrared ray sensor and
Lift car infrared ray sensor, so causes the cost of elevator monitoring system to be significantly increased；It addition, when the control of elevator self
During system fluctuation of service, it may appear that system problem (such as, staggered floor phenomenon), if, with central processing unit from floor address code
Circuit reads floor data, it is clear that correct number of floor levels can not accurately be detected, and ultimately result in hoistway door and extremely open
Open intelligent alarm system testing result to be forbidden to cut.
Summary of the invention
In view of this, it is necessary to provide a kind of construction cost low and there is the hoistway door detection of relatively high precision testing result
Warning system.
