Example one
With the more and more extensive application of elevator in daily life, elevator operation problem that door machine belt arouses in the elevator is also more and more. The belt in the elevator door motor is driven by the door motor driving wheel to rotate forward and reversely on one hand, and on the other hand, the belt pulls the door knife to drive the whole door motor to perform the door opening and closing actions of cyclic reciprocation, which is one of the most important parts in the transmission device, so that the loss degree of the belt is relatively higher than that of other door motor parts. When the belt teeth are worn and slipped, various problems can occur in the movement of the gantry crane. At present, the belt is maintained mainly by checking the tension degree of the belt through technicians and visually observing the abrasion condition of belt teeth so as to adjust or replace the belt. When the belt slips in the use process, technicians are required to drive to the site and enter a hoistway to check the site condition, the subjective judgment of the technicians is mainly relied on in the detection, and the subjective judgment is easily influenced by other factors, so that the belt detection accuracy is low.

As one example, steps S10 to S20 include: acquiring a preset operation frequency according to an actual condition, and enabling the gantry crane to operate according to a corresponding door opening and closing curve of the preset operation frequency through a gantry crane driver; the encoder is used for recording position information of the door panel when the door panel operates according to a set frequency in real time, converting the position information of the door panel into a pulse signal and obtaining a measurement pulse signal, the encoder can be installed on the gantry crane, the encoder is a door panel position information feedback device and is used for converting the position information of the door panel into the pulse signal and feeding the pulse signal back to a gantry crane driver, and the measurement pulse signal comprises pulse distribution information so as to monitor the real-time position information of the gantry crane; and acquiring a preset pulse signal, and comparing the preset pulse signal with the measurement pulse signal to detect whether a belt connecting the door panel and the motor slips or not.
In this embodiment, it should be noted that, in the prior art, a technician mainly performs tightness detection and visual detection on a belt of a gantry crane at regular intervals, the detection method greatly depends on the experience of the technician, and a detection result depends on subjective judgment of the technician, and the subjective judgment of the technician is easily affected by other factors such as a working state, environmental factors, physical factors and the like, so that the belt slip detection accuracy of the gantry crane is low. In this embodiment, mainly through regard as the control pulse signal that the door machine driver sent the door machine as predetermineeing pulse signal, gather the position information of door plant in the door machine and convert into measuring pulse signal through the encoder in the operation process to the position change information of representation door plant, and then judge according to the position change information of door plant whether the belt of connecting the motor and door plant skids. In the operation process, a pulse signal output by a door driver controls a motor in the door machine to operate, when a belt connecting the motor and a door plate slips, energy output by the motor can generate loss due to belt slipping, so that deviation can be generated between motion information of the door plate and expected motion information corresponding to a preset pulse signal, the motion information of the door plate is converted into a measurement pulse signal according to an encoder, the preset pulse signal and the measurement pulse signal are compared, and the slipping condition of the belt connecting the motor and the door plate is detected.

Wherein the first pulse distribution information at least includes a first pulse number of a door panel position, the second pulse distribution information at least includes a second pulse number of a door panel position, and the step of detecting whether a belt connecting the door panel and the motor slips or not according to the first pulse distribution information and the second pulse distribution information includes:

step S222, if the first pulse number is consistent with the second pulse number, judging that a belt connecting the door panel and the motor does not slip;
and step S223, if the first pulse number is inconsistent with the second pulse number, judging that a belt connecting the door panel and the motor slips.
In this embodiment, it should be noted that the first pulse distribution information at least includes a first pulse number of a door panel position, the second pulse distribution information at least includes a second pulse number of a door panel position, the first pulse number is a pulse number corresponding to the preset pulse signal when the door panel position is reached, and the second pulse number is a pulse number corresponding to the measurement pulse signal when the door panel position is reached.

and A30, calibrating the whole-process pulse signal according to the gate width pulse signal to obtain a preset pulse signal.
In this embodiment, it should be noted that the door width pulse signal is a pulse signal generated during the operation of the door panel of the door machine between the time when the door panel is completely closed and the time when the door panel is completely opened and the time when the door panel is completely closed, that is, the pulse signal generated during the door panel completes a stroke of the door width, the operation of the door machine is at a constant speed and a slow speed, the pulse signal in the operation of the door machine in the whole process is recorded, the whole process pulse signal at least includes a door panel position pulse signal, and the preset pulse signal at least includes a calibration door panel position pulse signal.
