Description

Detection alarm device and implementation method that hoistway door is opened extremely

Technical field

The present invention relates to elevator technical field, detection alarm device and implementation method that particularly a kind of hoistway door is opened extremely.

Background technology

Vertical operation elevator is as extraordinary transporting equipment, and the security of its operation and passenger's safety are closely bound up, and China's GB and various countries' elevator safety specification all explicitly call for elevator cage door, Room door lock are sealed in to safety return circuit, occurs to avoid shearing harm. But a large amount of generation artificially opened Room door and the unexpected accident that crashes into hoistway in recent years, causes the tragedy of personal injury constantly to occur. For this reason, in elevator industry, there is detection alarm and the prompting technology that a lot of non-leveling zones Room door is surprisingly opened.

Such as Chinese patent while opening " checkout gear that a kind of hoistway door the is improper " (patent No.: 01217409.2) announced a kind of safety detection device. This device is at patent " checkout gear and detection method when non-lift car place layer door is opened " (application number: on basis 00112131.6), increased by three lead-in wire magnetic control change-over switch CKZ in door pocket position, to realize the judgement of the floor position to opened Room door, send warning to realize at this layer. Its implementation is, utilize on the door of the Room in parallel with two magnetic switch that arrange in hoistway, when elevator is during at this layer, CK adhesive, and switch CKZ is by short circuit, does not report to the police; When elevator is not during at this layer, CK and CKZ disconnect, and the lead-in wire of CKZ also has output, can judge elevator not at this layer and layer door opened extremely, the warning device action at this layer of place, and prompting personnel approach. But there is following problem in it: 1) though magnetic switch and permanent magnet all can move in certain identification range, but at the every one deck of hoistway, a switch is only installed, and when installation site is fixed, for the elevator that possesses advance door opening function, the also not adhesive of the switch of hoistway, and Room door is opened, cause false alarm; In the time that elevator possesses story-leveling function again, hoistway door is opened, and car can be because of the passenger shift position of coming in and going out, and it is very high that two magnetic switch move inconsistent possibility, therefore that this mode practical operation is got up is unreliable. 2) this device cannot record the information that Room door is opened extremely, report to the police and disappear after recovering when unexpected opening the door, can not communicate by letter with apparatus for controlling elevator, potential safety hazard may or existence, be also unfavorable for repair and maintenance personnel to malfunction elimination.

Chinese patent " safety detection device of door of elevator waiting hall and detection method thereof " (publication number: CN101264839A) has been announced the improper device opening the door of a kind of detection layers door for another example, it is all provided with the stop signal processing apparatus that can process serial signal at each floor, whether the mechanical switch detection layers door that utilizes layer door place to install is opened, and imports the layer door status signal of opening into electric life controller in the mode of serial communication. The interior exclusive program of electric life controller, by the stop signal opening the door and elevator car position or relevant information contrast, draw and whether belong to non-this landing stop of car, and layer door opened extremely, can effectively improve elevator safety, utilize elevator self Men district identification signal, just avoided advance door opening or again when flat bed, two groups of identification delay and false alarms that pure mechanical switch easily causes. The method has the following disadvantages: 1) rely on electric life controller completely, obtain car position and judge, and at elevator in the time that car is slipped in power-off, tend to cause floor and actual floor in electric life controller not to be inconsistent phenomenon, now, there is very big potential safety hazard in this device; 2) in the time of elevator power failure or maintenance power-off, this device is also to play a role, and now Room door is that the probability of opening is very large by people, also very easily has an accident; 3) this invention is not described in and judge that Room door opens rear concrete alarming method extremely, is at elevator internal record, cannot play the warning personnel effect of this Room door beyond this point; 4) this invention requires, at every one deck, a stop signal processing apparatus being at least made up of CPU, serial communication controller etc. is all set, and this will increase cost greatly.

Chinese patent " Intelligent warning system for abnormal opening of hoistway door and safety detection method thereof " (application publication number: CN102085990A) has been announced a kind of new Room door and has extremely been opened detection and alarm method for another example, and its utilization is arranged on Room door infrared ray sensor, car infrared sensor and outside output processing circuit, central processing unit, floor address decoding circuitry, less radio-frequency radiating circuit, serial communication interface circuit and warning drive circuit composition. Implementation is, whether Room door infrared ray sensor detects hoistway door and opens, whether car infrared sensor detects car at this floor, when car is not at this floor and Room door while opening, after its central processing unit judges, send signal by wireless radio frequency circuit or serial circuit, and drive warning circuit, can realize in the time that Room door is opened extremely, and alarm export the signal of place floor. Also there is following deficiency in this invention: 1) this patent requires, at every one deck, Room door infrared ray sensor and car identification sensor are all set, and cost is very high, and the difficulty of installation and debugging is simultaneously higher; 2) use for a long time infrared ray sensor known, it is easily subject to visible ray interference, especially Room infrared ray sensor outdoors, and this patent is not described infrared sensor setting position, if identify the unlatching of Room door, blocking sensor also will inevitably be subject to passenger and pass in and out time; Car infrared sensor, because being arranged on identification car position in hoistway, is also easily hidden by hoistway dust, and which is prone to erroneous judgement; 3) when elevator is again when flat bed and advance door opening, this device also cannot be avoided two infrared sensors action inconsistence problems, and false alarm easily occurs.

The floor that can obtain Room door abnormal operation is 2 layers, because elevator is working properly, there is no staggered floor, program judges that abnormal Room bar layer is consistent with elevator control panel identification floor, and master control borad does not send advance door opening signal and fine motion flat bed signal, thereby programme-control O1 (2) mouthful of output high level 24V provides detection reference voltage to next floor. at O1(2) have after output software inhouse shielding input port I(2) electric potential signal, make it to keep the driver output of reporting to the police always. O2(2) output 24V is the warning device BJ2 power supply of the second floor, simultaneously, starting timer (being exemplified as 30s) now just only has the second floor to send the alarm of light or sound, and only having the fault message that occurs that Room door opens the door extremely 2nd floors to send to elevator main control board to show corresponding fault message, when having detected after I (1) mouthful of voltage of ground floor, whether program can start to rejudge from attic again has the floor that new Room door is opened extremely to occur, and for occurring that the floor of reporting to the police just shields its detection port, not at the I mouth input voltage that detects this floor, after timer timing stops, all delivery outlet O1(n), O2(n) stop output, again detect each layer of door state from top layer to bottom.

Suppose that elevator car position is at the level position of 3rd floors, and 3rd floors, 2nd floors, the Room door of 1st floor is all opened, there is the Room door of two floors extremely to open, and elevator is working properly, elevator floor does not have because slide is saved oneself or the phenomenon of staggered floor appears in other reasons, and elevator main control board does not send advance door opening signal and fine motion flat bed signal, now there is the touching switch J3 of 3rd floors, the touching switch J2 of 2nd floors, the magnetic switch G2 of 2nd floors, the touching switch J1 of 1st floor, the magnetic switch G1 of 1st floor disconnects, first this device detects that the voltage of I (2) mouthful is 0V, the floor that can obtain Room door abnormal operation according to table one is 2 layers, because elevator is working properly, there is no staggered floor, and master control borad does not send advance door opening signal and fine motion flat bed signal, thereby programme-control O1 (2) mouthful of output high level 24V provides detection reference voltage to next floor, O2(2) be the warning device BJ2 power supply of the second floor, due to two switch J1 of 1 floor, G1 disconnects, this device detects that again the voltage of I (1) mouthful is 0V, the floor that can obtain Room door abnormal operation according to table one is 1 layer, because elevator does not have staggered floor, and master control borad does not send advance door opening signal and fine motion flat bed signal, thereby this device programme-control O2 (1) mouthful of output high level 24V gives the warning driver BJ1 power supply of the first floor, and send to elevator main control board to show corresponding fault message the fault message that all occurs that Room door opens the door extremely 2nd floors and 1st floor. owing to being last floor that this device detects for 1st floor, whether program can start to rejudge from attic again has the floor that new Room door is opened extremely to occur, and for the floor that occurs reporting to the police just not at the I mouth input voltage that detects this floor. as above, starting O1(2) and O2(2) when output, timer starts, when timer meter triggers while interrupting, all delivery outlet O1(n), O2(n) stop output, again detect each layer state from top layer to bottom.

Suppose that elevator car position is at the level position of 3rd floors, and 3 balcony doors are all opened, and elevator is working properly, elevator floor does not have because slide is saved oneself or the phenomenon of staggered floor appears in other reasons, but elevator main control board sends advance door opening signal and fine motion flat bed signal, the magnetic switch of 3rd floors will be after Elevator landing stops could be effectively closed, now elevator is in the running status of opening the door, cause 3rd floors magnetic switch effectively not closed, the touching switch J3 of 3rd floors also disconnects, although this device detects that the input voltage of I (3) mouthful is 0V, but software makes O1(3) output 24V give next floor detection reference voltage is provided, O2(3) output 0V, now can not report to the police for 3rd floors, after advance door opening signal or fine motion blackout, make O1(3) output 0V. then continue the detection of next floor.

Suppose that elevator is because slide is saved oneself or staggered floor phenomenon appears in other reasons, be that lift car reality is at 2 floors, but the elevator floor of elevator main control board identification is at 3 floors, in the time that the Room of 3 floors door is opened extremely, the voltage that this device recognizes I (3) mouth is 0V, program judges that the current floor that extremely opens the door is consistent inconsistent with the floor of elevator main control board identification, no matter whether elevator there is advance door opening signal and fine motion flat bed signal, this device program is all controlled the warning driver BJ3 power supply of O2 (3) mouthful of output high level 24V to third story layer, simultaneously O1(3) output voltage is that lower circuit detects and uses, and send to elevator main control board to show corresponding fault message the fault message that occurs that Room door is opened extremely 3rd floors.

Suppose that car is not at 2nd floors, occur that abnormal Room door is opened for 2nd floors, and this device has carried out effectively reporting to the police to 2nd floors, but personnel keep in repair timely due to maintenance and debugging, make the Room door of 2nd floors effectively closed, get rid of this fault, 30S Interruption self-checking function while having added one to occur Room door abnormal conditions due to this device program part is (referring to accompanying drawing 3, this time change setting as required, herein for giving an example), its effect is when breaking down, this device is closed All Alerts output every 30S, recover the floor detection port of conductively-closed, and whether this layer of Room door also opened (certainly extremely from again detecting successively, all floors are also always in detection, not affected by timer), after detecting certain layer of Room door and extremely being opened, this layer of warning device at least continues warning 30S, guarantee safe enough. keeped in repair normally if there is the Room door of fault, after timer-controlled self-inspection appears in program, will no longer be reported to the police.

If elevator power failure or building have a power failure, while can't detect the normal working signal of elevator, this device still can independently be worked, continue to detect the Room door that all quilts are opened extremely, and respective storey send alarm signal and in the memory of device record trouble information, recover after normal power supply to send to elevator main control board to show the fault message of record before at building.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
