Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Figure 1, be the schematic flow sheet of elevator door control method embodiment of the present invention, comprise:
The step that door control system performs:
Step S101: the data packet that the signal receiving end receiving elevator light curtain sends, and from described data packet, obtain light curtain signal;
Step S102: judge whether described light curtain signal meets the verification condition of setting, if not, enters step S103;
This step tentatively judges whether light curtain signal exists the step of fault, and the verification condition of setting can be determined according to light curtain fault.Such as, the verification condition of setting can be the level data that the level data of light curtain signal meets setting, also can be that the check bit of light curtain signal is correct.Namely step S102 can comprise:
In addition, elevator light curtain here, generally comprises the signal receiving end of elevator light curtain and the signal transmitting terminal of elevator light curtain.
Step S103: according to prefixed time interval, first power-off is carried out to light curtain, then power on;
Prefixed time interval can set as the case may be.Such as, can determine according to the performance of light curtain own, also can determine according to the light curtain signal period.Such as time gap is T, then first carry out power-off to light curtain, then after T time, powers on.
Step S104: after the power-up, judges whether the light curtain signal received meets described verification condition, if not, enters step S105;
Step S105: send light curtain breakdown signal to apparatus for controlling elevator;
Step S107: receive close the door instruction and slow speed signal that apparatus for controlling elevator sends, and close elevator door according to close the door instruction and slow speed signal with the speed preset, described default speed is less than the normal door closing speed of elevator door;
Slow speed signal can comprise default speed, and namely apparatus for controlling elevator controls the size of pre-set velocity.Preferably, slow speed signal can be only an indicator signal, and default speed is stored in door control system.After door control system receives slow speed signal, close the door at a slow speed according to the pre-set velocity that oneself stores.The burden of transmission can be alleviated like this.Here pre-set velocity be set to and be less than the normal door closing speed of elevator door, object is to make door closing speed slower, to guarantee safety.
The step that apparatus for controlling elevator performs:
Step S106: receive described light curtain breakdown signal, and obtain in elevator cage simultaneously and close gate signal, close in described cab gate signal effective time, send to door control system close the door instruction and slow speed signal.
Obtaining in elevator cage and close gate signal can be detect the state of door close button in lift car, obtains status signal.Close gate signal in cab effective, namely in car, the state of door close button is starting state, and in such as car, door close button is manually pressed by user.
The present invention program can realize based on elevator device as shown in Figure 2.As shown in Figure 2, the signal receiving end 220 (detectable signal sending end) of the signal transmitting terminal 210 (detectable signal sending end) comprising the elevator light curtain being installed on elevator door side, the elevator light curtain being installed on elevator door opposite side, door control system 230 and apparatus for controlling elevator 240 (also can be described as elevator main control board).The signal transmitting terminal of elevator light curtain, the signal receiving end of elevator light curtain are connected with door control system respectively, and door control system is connected with apparatus for controlling elevator.During the data packet that the signal receiving end receiving elevator light curtain sends, the mode of serial communication can be adopted to receive, adopt asynchronous communication.Data packet can be 11 bit data forms: 1 start bit, 8 data bit, 1 even parity bit, 1 stop bit.Packet information can comprise: the status information, luminous point quantity information etc. of light tentiform state, each luminous point.As shown in Figure 3, be signal transmitting terminal and the receiving end principle of work schematic diagram of elevator light curtain of the present invention.Comprise the signal transmitting terminal 310 of elevator light curtain and the signal receiving end 320 of elevator light curtain.
In step s 106, if close the door invalidating signal in cab, and do not receive light curtain when blocking signal, elevator door keeps open state.After certain interval of time, apparatus for controlling elevator can send to door control system command signal of closing the door.Wherein, light curtain blocks in the setting-up time of signal before elevator door is completely closed, and elevator door still exists light curtain when blocking, the signal that door control system sends to apparatus for controlling elevator.
Wherein in an embodiment, can repeatedly carry out power-off, power on and deterministic process, to improve the accuracy rate judging light curtain fault.If after namely the described light curtain signal received does not meet described verification condition, described before apparatus for controlling elevator transmission light curtain breakdown signal, the step that door control system performs also comprises:
Repeat, according to prefixed time interval, first power-off is carried out to light curtain, then power on, and after the power-up, judge whether the light curtain signal received meets the step of described verification condition, until repeatedly setting number of times, if when still not meeting described verification condition, enter and send light curtain breakdown signal step to apparatus for controlling elevator.
The present embodiment carrying out first time power-off, power on, judge process after, if do not met Rule of judgment, then can carry out second time power-off, power on, judge to process, by that analogy, number of processes can free setting.By repeatedly processing, the accuracy rate judging light curtain fault can be improved.
In addition, elevator door control system can record and not meet verification condition number of times, when number of times is greater than set point number, receives instruction of closing the door later at every turn, all closes elevator door with the speed preset.
When the light curtain signal received does not meet described verification condition, elevator door has two states, and one is halted state, and one is state of kinematic motion, and namely elevator door speed is non-vanishing.During elevator door halted state, directly can judge whether fault, if so, then send light curtain breakdown signal.When elevator door is state of kinematic motion, needs to control elevator door and stop.Namely in one embodiment:
The step that door control system performs also comprises:
A1: described in after the light curtain signal that receives do not meet described verification condition, before sending light curtain breakdown signal to apparatus for controlling elevator, when detecting that the speed of elevator door is non-vanishing, slow down and stop elevator door;
It can be judged result before power-off, power on operation that light curtain signal does not meet verification condition, also can be the judged result after power-off, power on operation.When detecting that light curtain signal does not meet verification condition and elevator door speed is non-vanishing, can slow down stopping elevator door.Wherein, the stopping elevator door that slows down controls elevator door deceleration to stop.
A2: in the setting-up time before elevator door stops, luminous point status information is obtained from described data packet, judge that whether there is light curtain blocks when elevator door closing according to the luminous point status information of data packet, if exist, send light curtain to apparatus for controlling elevator and block signal;
A3: when receiving the door open command that apparatus for controlling elevator sends, and open elevator door according to described door open command;
The step that apparatus for controlling elevator performs also comprises:
A4: receive described light curtain and block signal, sends door open command to door control system.
The present embodiment is when elevator door speed is non-vanishing, and first slowing down stops elevator door.Now, elevator door is in non-fully open mode, and door control system controls elevator door and first opens, and opens rear just transmission light curtain breakdown signal, and receive close the door instruction and the slow speed signal that apparatus for controlling elevator sends, and close elevator door according to close the door instruction and slow speed signal with the speed preset.
Judge that the method for the verification condition of the whether satisfied setting of light curtain signal has a lot, wherein in an embodiment, can judge whether the level data of described light curtain signal meets the level data of setting.The level data of setting can be high level and the low-level data with certain logical laws.Light curtain is when Rx end broken string, and door control system receives permanent High level signal, now also can determine disconnection fault.Under light curtain Tx holds broken string situation, Rx sends high level signal, can broken string be detected.
Such as, in an application example, if the light curtain signal that door control system receives is high level signal always, be judged as light curtain disconnection fault.Before transmission light curtain breakdown signal, door control system can also control elevator door and reduce speed now, in setting-up time (100ms before such as stopping) before elevator door stops, if signal still mal, then can send light curtain and block signal to apparatus for controlling elevator.Apparatus for controlling elevator receives described light curtain and blocks signal, and obtains in elevator cage simultaneously and close gate signal, if close the door in described cab invalidating signal time, then send door open command to door control system.Door control system opens elevator door.
Door control system receive signal mal start calculate, setting-up time section (such as, the light curtain signal data received 500ms) is always unchanged, preliminary judgement is fault, carry out first time to light curtain power supply and forfeit electronic work, the time gap forfeiting electricity is prefixed time interval (can be such as 500ms).
Judge through the time of prefixed time interval (such as 500ms) after light curtain re-powers, if fault is not also eliminated, then carry out second time and forfeit electronic work.
After light curtain second time re-powers, then experience the determination time of prefixed time interval (such as 500ms), if fault is not still eliminated; Third time forfeits electronic work to light curtain, if through the acquisition of signal of prefixed time interval (such as 500ms), signal does not still return to normal condition, door control system confirms light curtain fault, then sending light curtain breakdown signal to apparatus for controlling elevator, keep light curtain power-up state simultaneously, blocking signal from sending the moment, remain valid, unless or unobstructed signal trouble free signal exists always.
Apparatus for controlling elevator receives described light curtain breakdown signal, and obtains in elevator cage simultaneously and close gate signal, close in described cab gate signal effective time, send to door control system close the door instruction and slow speed signal, and buzzer warning can controlled at closing time.If close the door in described cab during invalidating signal, elevator door keeps open state, if light curtain breakdown signal exists always, after certain interval of time, apparatus for controlling elevator sends and closes the door command signal to door control system, and after door-closing in-place, if apparatus for controlling elevator detects light curtain, breakdown signal still exists, then think light curtain fault, and record.When pass gate signal is effective in each car later, then all closes the door at a slow speed with pre-set velocity, and ring buzzer phone.
Wherein in an embodiment, the described verification condition step judging that whether described light curtain signal meets setting comprises: judge that whether the check bit of described light curtain signal is correct.
This embodiment is by judging whether check bit correctly judges light curtain whether fault.Such as, in an application example, if receive signal, occur verification off-square situation, first door control system makes a deceleration stop, in the setting-up time before elevator door stops, still there is light curtain when blocking in elevator door, then sends light curtain to apparatus for controlling elevator and block signal.Gate loses this bag light curtain data packet, and misregistration number of times, waits for next idle high level state, if continuous 3 times are made mistakes, door control system is judged as preliminary fault; If in decision process, normally idle high level cannot be detected, the time, more than after 2s, is judged to be the preliminary fault of light curtain equally.
Avoid after spare bits to interference, next bag data cannot be detected, program cannot be jumped out, after carrying out first time power-off, repeat testing process above, if fault exists, carry out second time power-off again, repeat identical testing process, if fault exists, then export light curtain breakdown signal to apparatus for controlling elevator.
These two Rule of judgment only using one of them as each Rule of judgment judged, also simultaneously using two as Rule of judgment, thus can can improve judgment accuracy.In addition, light curtain fault can also be judged by judging whether light curtain crashes.
Wherein in an embodiment, described data packet also comprises luminous point status information, and the step that door control system performs also comprises:
After the power-up, when the light curtain signal received meets described verification condition, from described data packet, obtain luminous point status information, judge that whether there is light curtain blocks when elevator door closing according to the luminous point status information of data packet, if exist, then slow down and stop elevator door;
And in setting-up time before elevator door stops, still there is light curtain when blocking in elevator door, sends light curtain block signal to apparatus for controlling elevator;
Receive the door open command that apparatus for controlling elevator sends, and open elevator door according to described door open command;
The step that apparatus for controlling elevator performs also comprises:
Receive described light curtain and block signal, send door open command to door control system.
Certainly, if there is not light curtain during elevator door closing when blocking, elevator door can be controlled and close the door with normal door closing speed.
The present embodiment is when not having light curtain fault, whether detection exists light curtain blocks, the judgement of signal is blocked by light curtain, unnecessary counter of door control system can be reduced open, improve the service efficiency of elevator, when the time of blocking is shorter, just do not need anti-enabling, save time, raise the efficiency.
Wherein, setting-up time can free setting.Can be such as 100ms.Door control system detects that light curtain reduces speed now after blocking, and in the 100ms moment before stopping, again judging whether light curtain blocks, if now block blackout, does not then send and blocks signal to apparatus for controlling elevator, continue to close the door.If now block signal still to exist, then send and block signal to apparatus for controlling elevator, when apparatus for controlling elevator judges now to close the door invalidating signal in cab, send enabling signal, door control system performs anti-door open command.If now close gate signal in cab effectively (than pressing door close button by force if any people), then continue to close the door.
Wherein in an embodiment, the step that door control system performs also comprises:
