The step of carrying out on door control system:
Step S101: receive the data packet of the signal receiving end transmission of elevator light curtain, and obtain light curtain signal from described data packet;
Step S102: judge that whether described light curtain signal meets the verification condition of setting, and if not, enters step S103;
This step is tentatively to judge 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 that the level data of light curtain signal meets the level data of setting, and can be also that the check bit of light curtain signal is correct.Be that step S102 can comprise:
In addition, the 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 Preset Time interval, light curtain is first carried out to power-off, then power on;
Preset Time interval can be 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, light curtain is first carried out to power-off, then, after the T time, power on.
Step S104: after powering on, judge that whether the light curtain signal receiving 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 of presetting, described default speed is less than the normal door closing speed of elevator door;
Slow speed signal can comprise default speed, i.e. the size of apparatus for controlling elevator control pre-set velocity.Preferably, slow speed signal can be only an indicator signal, and default speed is stored in door control system.Door control system receives after slow speed signal, and the pre-set velocity of storing according to oneself is closed the door at a slow speed.Can alleviate like this burden of transmission.Here pre-set velocity is made as and is less than the normal door closing speed of elevator door, object is in order to make door closing speed slower, to guarantee safety.
The step of carrying out on apparatus for controlling elevator:
Step S106: receive described light curtain breakdown signal, and obtain in elevator cage simultaneously and close gate signal, close gate signal when effective in described cab, send to door control system close the door instruction and slow speed signal.
Obtaining and close gate signal in elevator cage can be to detect the state of door close button in lift car, obtains status signal.In cab, close gate signal effective, in car, the state of door close button is starting state, such as door close button in car is manually pressed by user.
The present invention program can realize on the elevator device based on as shown in Figure 2.As shown in Figure 2, comprise the signal transmitting terminal 210 (detectable signal sending end) of the elevator light curtain that is installed on elevator door one side, the signal receiving end 220 (detectable signal sending end) that is installed on the elevator light curtain of 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.While receiving the data packet of signal receiving end transmission of elevator light curtain, can adopt the mode of serial communication 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: status information, the 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 S106, if close the door invalidating signal in cab, and not receive when light curtain blocks signal, elevator door keeps opening state.After certain interval of time, apparatus for controlling elevator can send the command signal of closing the door to door control system.Wherein, light curtain blocks in the setting-up time of signal before the complete closure of elevator door, when elevator door still exists light curtain to block, and the signal that door control system sends to apparatus for controlling elevator.
In an embodiment, can repeatedly carry out power-off, power on and deterministic process therein, to improve the accuracy rate that judges light curtain fault.If after the described light curtain signal receiving does not meet described verification condition, described before apparatus for controlling elevator transmission light curtain breakdown signal, the step of carrying out on door control system also comprises:
Repeat according to Preset Time interval light curtain is first carried out to power-off, then power on, and after powering on, whether the light curtain signal that judgement receives meets the step of described verification condition, until repeatedly setting number of times, if while still not meeting described verification condition, enter to apparatus for controlling elevator and send light curtain breakdown signal step.
The present embodiment is carrying out power-off for the first time, is powering on, judges after processing, if do not met Rule of judgment, can carry out power-off for the second time, power on, judges processing, and by that analogy, number of processes can free setting.By repeatedly processing, can improve the accuracy rate that judges light curtain fault.
In addition, elevator door control system can record and not meet verification condition number of times, in the time that number of times is greater than set point number, receives the instruction of closing the door later at every turn, all closes elevator door with the speed of presetting.
In the time that the light curtain signal receiving does not meet described verification condition, elevator door has two states, and one is halted state, and one is state of kinematic motion, and elevator door speed is non-vanishing.When elevator door halted state, can directly judge whether fault, if so, send light curtain breakdown signal.In the time that elevator door is state of kinematic motion, need to controls elevator door and stop.In one embodiment:
The step of carrying out on door control system also comprises:
A1: described in the light curtain signal that receives do not meet after described verification condition, send before light curtain breakdown signal to apparatus for controlling elevator, detect when the speed of elevator door is non-vanishing, slow down and stop elevator door;
It can be power-off that light curtain signal does not meet verification condition, the preoperative judged result that powers on, can be also power-off, power on operation after judged result.Detecting that light curtain signal does not meet verification condition and elevator door speed when non-vanishing, can slow down and stop elevator door.Wherein, slow down stop elevator door be control elevator door slow down stop.
A2: in the setting-up time before elevator door stops, from described data packet, obtain luminous point status information, judge whether exist light curtain to block when the 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 opening the door when instruction that apparatus for controlling elevator sends, and according to the described instruction unpack elevator door that opens the door;
The step of carrying out on apparatus for controlling elevator also comprises:
A4: receive described light curtain and block signal, send to door control system the instruction of opening the door.
The present embodiment is in the time that elevator door speed is non-vanishing, first slows down and stops elevator door.Now, elevator door is in non-full open position, and door control system control elevator door is first opened, and opens the rear light curtain breakdown signal that just sends, 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 of presetting.
Judge method that whether light curtain signal meets the verification condition of setting have a lot of in, in an embodiment, can judge whether the level data of described light curtain signal meets the level data of setting therein.The level data of setting can be high level and the low-level data with certain logical laws.Light curtain is the in the situation that of Rx end broken string, and door control system receives lasting high level signal, now also can determine disconnection fault.In light curtain Tx end broken string situation, Rx sends high level signal, broken string can 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 be controlled elevator door and reduce speed now, in setting-up time (such as the 100ms before stopping) before elevator door stops, if still mal of signal 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 pass gate signal in elevator cage simultaneously, if while closing the door invalidating signal in described cab, sends to door control system the instruction of opening the door.Door control system is opened elevator door.
Door control system receive signal mal start calculate, setting-up time section (such as, the light curtain signal data receiving 500ms) is always unchanged, preliminary judgement is fault, light curtain power supply is forfeited to electronic work for the first time, and forfeiting electric time gap is Preset Time interval (such as being 500ms).
Time through Preset Time interval (such as 500ms) after light curtain re-powers is judged, if fault is not also eliminated, forfeits for the second time electronic work.
After light curtain re-powers for the second time, then experience the judgement time at Preset Time interval (such as 500ms), if fault is not still eliminated; For the third time light curtain is forfeited to electronic work, if through the acquisition of signal of Preset Time interval (such as 500ms), signal does not still return to normal condition, door control system is confirmed light curtain fault, send 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, closes gate signal when effective in described cab, sends close the door instruction and slow speed signal, and can control at closing time buzzer warning to door control system.If close the door in described cab when invalidating signal, elevator door keeps opening 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, think light curtain fault record.When pass gate signal is effective in later each car, all closes the door at a slow speed with pre-set velocity, and ring buzzer phone.
