The reflector is arranged on the door leaf on one side of the elevator landing door through the magnetic seat.
The laser detector is arranged on the door frame at the other side of the elevator landing door through a magnetic seat.
And the controller controls the laser detector to send a last detection signal after receiving a signal for completing the door opening or closing of the elevator.
Advantageous effects
Since the technical scheme is used, compared with the prior art, the utility model, have following advantage and positive effect: the utility model discloses an installation reflector panel on the door leaf of elevator layer door, installation laser detector on the door frame, laser detector be opening the door or the periodic transmission detected signal of closing the door, can obtain laser through laser detector and send to the time of returning to can obtain the door width, can obtain the door width difference through adjacent twice laser emission, recycle the poor and functioning speed that the emission time interval can obtain elevator layer door of door width.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The embodiment of the utility model relates to a non-contact elevator switch door speed detection device, as shown in fig. 1, including reflector panel 1, laser detector 2 and controller 3, reflector panel 1 is installed on door leaf 4 of one side of elevator layer door through the magnetic base, laser detector 2 is installed on door frame 5 of the other side of elevator layer door through the magnetic base, reflector panel 1 and laser detector 2 are located the same height; the laser detector 2 is connected with the controller 3, the controller 3 controls the laser detector 2 to periodically send out detection signals after receiving door opening or closing signals of the elevator, and the controller 3 calculates the real-time elevator floor width according to feedback signals received by the laser detector 2. The controller in this embodiment may be a 51-series single chip microcomputer, and the single chip microcomputer may be connected to a display and a memory.
The controller of the embodiment is connected with an elevator control system, when the elevator control system sends a door opening signal, the controller triggers the laser detector, the laser detector periodically sends a detection signal, when the detection signal is sent for the first time, the laser detector sends laser to the reflector, the laser is reflected by the reflector and then fed back to the laser detector, the laser detector subtracts the time of sending the laser from the time of receiving the feedback signal, and the time difference is multiplied by the light speed, so that the door width when the detection signal is sent for the first time can be obtained; when the detection signal is sent out for the second time, the gate width when the detection signal is sent out for the second time can be obtained as in the first time. At the moment, the door width of the elevator landing door can be known by subtracting the door width of the first time from the door width of the second time, the distance of the elevator landing door in the time interval of sending the detection signals twice is the door width difference of the two times, and the door opening speed of the elevator landing door can be obtained by dividing the door width difference by the time difference of sending the detection signals twice. In a similar way, the door opening speed of different elevator landing doors with different door widths can be obtained after N times, then the door width is taken as an abscissa, and the door opening speed of the elevator landing door is taken as an ordinate, so that a door opening speed curve can be obtained.
In order to guarantee that the laser detector can send a detection signal when the elevator landing door is opened, therefore, after the controller receives the elevator door opening completion signal, the laser detector is controlled to send a last detection signal, so that the situation that the measurement is inaccurate due to the fact that the time for sending the signal by the laser detector is not reached after the elevator landing door is opened can be avoided.
Similarly, the door closing speed of the elevator landing door can be obtained by the above method, that is, when the elevator control system sends a door closing signal, the controller triggers the laser detector, the laser detector periodically sends a detection signal, when the detection signal is sent for the first time, the laser detector sends laser to the reflector, the laser is reflected by the reflector and then fed back to the laser detector, the laser detector subtracts the time for sending the laser from the time for receiving the feedback signal, and the time difference is multiplied by the light speed, so that the door width when the detection signal is sent for the first time can be obtained; when the detection signal is sent out for the second time, the gate width when the detection signal is sent out for the second time can be obtained as in the first time. At the moment, the door width of the elevator landing door can be known by subtracting the door width of the first time from the door width of the second time, the distance of the elevator landing door in the time interval of sending the detection signals twice is the door width difference of the two times, and the door closing speed of the elevator landing door can be obtained by dividing the door width difference by the time difference of sending the detection signals twice. Similarly, the closing speed of different elevator landing doors with different door widths can be obtained after N times, then the door width is taken as an abscissa, and the closing speed of the elevator landing door is taken as an ordinate, so that a closing speed curve can be obtained. In order to ensure that the laser detector can send a detection signal when the door of the elevator floor is closed, the laser detector is controlled to send a last detection signal after the controller receives the door closing completion signal of the elevator.
The discovery of being difficult, the utility model discloses an installation reflector panel on the door leaf of elevator layer door, installation laser detector on the door frame, laser detector be opening the door or the time of closing the door periodic transmission detected signal, can obtain laser through laser detector and send to the time of returning to can obtain the door width, can obtain the door width poor through adjacent twice laser emission, recycle the door width poor and the functioning speed that the emission time interval can obtain elevator layer door.
