Description
Technical field
The present embodiments relate to elevator technology, more particularly to a kind of apparatus for controlling elevator and method.
Background technology
Elevator light curtain is a kind of light formula safety protector of elevator door, suitable for elevator and Cargo Lift, available for protection electricity
The safety of terraced passenger.
At present, the elevator light curtain overwhelming majority is plane horizontal detection light curtain, and such a light curtain is generally comprised installed in elevator
The infrared transmitter and infrared remote receiver of gate both sides.Setting is uniformly distributed in the short transverse of infrared transmitter interior edge elevator door
There are multiple (generally 32 or 16) infrared emission components, infrared receiver component is correspondingly arranged in infrared remote receiver, in electricity
When terraced door is in opening, the light that infrared transmitter is sent can form an infrared ray protection light curtain.When any of which one
When beam light is blocked, it can learn and detect shelter, apparatus for controlling elevator can control gate phase down and open, until multiplying
Visitor or obstacle leave after warning region elevator door can normal switching-off, so as to reach safeguard protection purpose, can so avoid electricity
The generation of terraced clamping accident.
This traditional infrared light curtain detection mode, only when people or thing appear in sheltered from elevator door plane of motion it is red
Can be just detected during outside line and control elevator to open the door again, because of the limited amount of infrared emission component, light in light curtain it
Between larger space be present, so the detection based on traditional light curtain can have blind area.During the use of elevator, it is frequently encountered
Shelter is appeared in the range of blind area and can not be detected, and causes elevator door to clip to the situation of shelter when closing.For example people pushes away
When bicycle and entering car, it can not be detected because tire thickness is less than blind area scope, cause bicycle to be knocked；And for example
Hand is stretched into the range of blind area and crushed by elevator door by Tong Yin.
The content of the invention
The present invention provides a kind of apparatus for controlling elevator and method, to solve in existing elevator controlling scheme because of check frequency
It is larger and occur elevator door by mistake close the problem of.
In a first aspect, the embodiments of the invention provide a kind of apparatus for controlling elevator, including the first infrared light curtain detection unit,
Second infrared light curtain detection unit and control device；
The first infrared light curtain detection unit is used to be formed in parallel with the horizontal infrared light curtain of elevator door and blocked
Analyte detection；
The second infrared light curtain detection unit is used to be formed in parallel with longitudinal infrared light curtain of elevator door and blocked
Analyte detection；
The control device respectively with the first infrared light curtain detection unit and the second infrared light curtain detection unit
It is connected, for the testing result control according to the first infrared light curtain detection unit and the second infrared light curtain detection unit
Make the switch motion of the elevator door.
Second aspect, the embodiments of the invention provide a kind of elevator control method, this method is carried based on the embodiment of the present invention
The apparatus for controlling elevator of confession, including：
When elevator door is in non-completely closed state, blocked if the first infrared light curtain detection unit is not detected by
Thing, and the second infrared light curtain detection unit detects shelter, then controls the elevator door to open.
The present invention solves elevator by the way that the first infrared light curtain detection unit is combined with the second infrared light curtain detection unit
Light curtain detecting system causes elevator to be closed the door by mistake because blind area is big, the problems such as causing elevator to press from both sides people, realizes elevator and more safely may be used
The operation leaned on.

Step 303, control elevator door are opened.
Step 304, judge whether the second infrared light curtain detection unit detects shelter, if so, then performing step 305；
Otherwise, step 306 is performed.
Step 305, control elevator door open, and send will close the door please remove shelter warning, perform step 307.
Exemplary, send warning and may be notified that either reminding passengers enter car or occlusion removal thing as early as possible.
Step 306, control elevator door are closed.
Exemplary, during elevator door is closed, alarming device can be closed.
Step 307, continue in T1 durations to judge whether the second infrared light curtain detection unit detects shelter, if so,
Then perform step 308；Otherwise, step 306 is performed.
It is exemplary, if the second infrared light curtain detection unit is not detected by shelter, and the first infrared light curtain detection unit
Shelter is detected, also can perform step 308.
Step 308, judge whether to detect in call shutdown instruction together, if so, then performing step 306；Otherwise, step is performed
309。
Exemplary, if in T1 durations, inside call shutdown instruction continuously effective together, then can control elevator door to close.If
Close the door before completing, inside call shutdown instruction together and disappear, can control elevator door to open, play a protective role.
Step 309, control elevator door to close at a slow speed after T1 durations, perform step 310.
Exemplary, carrying out at a slow speed at closing time, also alarming device being driven to provide warning.
Step 310, judge whether to detect in T2 durations it is inside and outside call information together, if so, then performing step 311；Otherwise, perform
Step 312.
Information is called together inside and outside step 311, control elevator response.
Step 312, switch gate action is performed, if the second infrared light curtain detection unit detects shelter in same position,
Then prompt message is sent to the Surveillance center that correspondence with apparatus for controlling elevator be present.
Exemplary, if after elevator door is closed at a slow speed, it is never interior in T2 durations to call floor information together and call information together outside
When, switch gate can be carried out and reaffirm whether be same position, if second detection device can also detect shelter, by
Control device sends information to property Surveillance center, so as to check in time detection unit whether failure and remove foreign matter, prevent different
Thing causes damage to elevator cage and gate etc..
A kind of elevator control method that the embodiment of the present invention five provides, can integrate the first infrared light curtain detection unit and second
The testing result of infrared light curtain detection unit rationally to control the switch motion of elevator door, reduces the hair that elevator misses door close event
It is raw, and prompting processing can be carried out to the shelter for hindering elevator door to close in time, it ensure that the normal operation of elevator.
Pay attention to, above are only presently preferred embodiments of the present invention and institute's application technology principle.It will be appreciated by those skilled in the art that
The invention is not restricted to specific embodiment described here, can carry out for a person skilled in the art various obvious changes,
Readjust and substitute without departing from protection scope of the present invention.Therefore, although being carried out by above example to the present invention
It is described in further detail, but the present invention is not limited only to above example, without departing from the inventive concept, also
Other more equivalent embodiments can be included, and the scope of the present invention is determined by scope of the appended claims.
