Description

Technical Field

[0001] The embodiments of the present application relate to the field of elevator technology, and in particular to an elevator control method, an elevator control device, and a storage medium. Background Art

[0002] The existing disc motor converts the rotating magnetic field into a traveling wave magnetic field moving in the horizontal direction, forming an innovative planar linear ring motor. The thin and large permanent magnets in the disc motor can obtain greater magnetic excitation, the rotor and stator have the same diameter and are parallel, and the diameter of the traction wheel integrated with the rotor is always smaller than the rotor diameter, so it can easily obtain greater torque.

[0003] Disc motors are widely used in the elevator field. The encoder is generally installed on the side of the elevator motor traction wheel. The encoder's friction wheel is used to ensure that the encoder's rotation is synchronized with the motor traction wheel. A photoelectric switch is installed on the motor traction wheel to detect the absolute position signal of the motor. The absolute position signal generates a zero-position pulse signal in one circle, which is used to correct the motor's magnetic pole position.

[0004] Since the encoder and motor shaft are connected through the encoder's friction wheel, the encoder's friction wheel will wear out after the elevator has been running for a long time, which will cause the elevator's floor data to change.

[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In the description of the embodiments of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0047] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0048] Disc motors are widely used in the elevator field. The encoder is generally installed on the side of the elevator motor traction wheel. The encoder's friction wheel is used to ensure that the encoder's rotation is synchronized with the motor traction wheel. A photoelectric switch is installed on the motor traction wheel to detect the absolute position signal of the motor. The absolute position signal generates a pulse signal for one circle to correct the motor magnetic pole position.

[0049] Since the encoder and the motor shaft are connected through the friction wheel of the encoder, when the elevator runs for a long time, the friction wheel of the encoder will be worn, which will cause the floor data of the elevator to change. When the floor data changes significantly, the elevator will be under-leveled or over-leveled, which will seriously affect the normal operation of the elevator. Therefore, the embodiment of the present application provides an elevator control method that can avoid the elevator from being under-leveled or over-leveled, ensuring the normal operation of the elevator. Figure 1 As shown, the following steps are included:

[0050] 101. Before the elevator is put into operation, record the floor data of each floor in the elevator shaft and the initial transmission ratio between the traction wheel and the friction wheel of the encoder.

[0051] In the embodiment of the present application, before the elevator is put into operation, the elevator control system can control the elevator to conduct a trial run at a certain operating speed, record the floor data of each floor of the elevator shaft, and the initial transmission ratio between the elevator traction wheel and the friction wheel of the encoder, wherein the encoder is installed on the traction wheel of the elevator. The floor data of each floor of the elevator shaft can be detected and recorded based on the encoder installed on the traction wheel of the elevator, that is, the floor data of each floor is learned and stored in the corresponding storage space. Specifically, the number of pulses between adjacent floors on the elevator shaft can be detected based on the encoder, that is, the number of pulses detected by the encoder when the elevator runs from a certain floor to the next adjacent floor, such as the number of pulses between the bottom floor and the second bottom floor, or the number of pulses between the second top floor and the top floor. Then, multiple pulse numbers are used as the floor data of the corresponding floors, such as the number of pulses between the bottom floor and the second bottom floor can be used as the floor data of the second bottom floor.

[0052] In the embodiment of the present application, before the elevator is put into operation, the initial transmission ratio between the traction wheel and the friction wheel of the encoder can also be obtained and recorded, that is, the initial transmission ratio J0 between the traction wheel and the friction wheel of the encoder is learned and stored in the corresponding storage space. Specifically, the initial transmission ratio between the traction wheel and the friction wheel of the encoder can be obtained by dividing the diameter of the traction wheel by the diameter of the friction wheel of the encoder. Among them, the transmission ratio in the embodiment of the present application represents: the ratio of the speed of the traction wheel to the speed of the friction wheel of the encoder.

[0053] 102. After the elevator is put into operation, the target pulse number of the traction wheel is determined based on the pulse number between two adjacent zero-position pulse signals detected by the encoder.

[0054] After the elevator is put into operation, the target pulse number of the traction wheel is determined based on the number of pulses between two adjacent zero-position pulse signals detected by the encoder; wherein the zero-position pulse signal (Z-phase signal) is a reference pulse signal, and the traction wheel outputs a zero-position pulse signal for each rotation of the traction wheel, and the output zero-position pulse signal can be detected by a photoelectric switch. During the steady-speed operation of the elevator, the number of pulses detected by the encoder between two zero-position pulse signals can be counted. Among them, the multiple pulse numbers corresponding to multiple groups of two adjacent zero-position pulse signals can be counted, and the multiple pulse numbers can be averaged or median to obtain the target pulse number of the traction wheel. It can be understood that the more the number of multiple pulse numbers counted, the better the anti-interference ability of the elevator control system.

[0055] 103. Determine the current transmission ratio between the traction wheel and the friction wheel of the encoder based on the target pulse number of the traction wheel and the pulse line number of the encoder.

[0056] After obtaining the target pulse number of the traction wheel, the current transmission ratio between the traction wheel and the friction wheel of the encoder can be determined based on the target pulse number of the traction wheel and the pulse line number of the encoder. The pulse line number of the encoder is the number of engraved lines on the photoelectric code disk of the encoder, and the pulse line number is multiplied by the frequency multiplication coefficient to detect the pulse number. Specifically, the target pulse number of the traction wheel can be divided by the pulse line number of the encoder to obtain the current transmission ratio Jnow (i.e., the currently calculated transmission ratio) between the traction wheel and the friction wheel of the encoder.

[0057] 104. Update the current transmission ratio based on the initial transmission ratio and the preset update weight to obtain a real-time transmission ratio.

[0058] It is understandable that during the normal operation of the elevator, since the friction wheel of the encoder and the traction wheel measure the speed by friction, after running for a long time, the traction wheel will have friction loss. After a long period of loss, the diameter of the friction wheel of the encoder will become shorter. If the deviation is too large, it will cause the elevator's detected position and actual position to deviate, requiring manual re-learning of the well.

[0059] Therefore, in the embodiment of the present application, after obtaining the current transmission ratio, the current transmission ratio can be updated based on the initial transmission ratio and the preset update weight to obtain the real-time transmission ratio. That is, the initial transmission ratio can be used as the initial value of the real-time transmission ratio, and the current transmission ratio can be updated by the preset update weight to obtain the updated real-time transmission ratio. Among them, the preset update weight is related to the update speed of the transmission ratio. The larger the preset update weight, the slower the update speed of the transmission ratio, and the smaller the preset update weight, the faster the update speed of the transmission ratio. That is, by updating the current transmission ratio to obtain the updated real-time transmission ratio, the deviation between the detected position and the actual position of the elevator can be overcome, without the need for manual re-performing of the shaft self-learning.

[0060] 105. Based on the real-time transmission ratio and the initial transmission ratio, update the floor data of each floor, and use the updated floor data to perform elevator leveling control.

[0061] After obtaining the real-time transmission ratio between the traction wheel and the friction wheel of the encoder, the floor data of each floor can be updated based on the real-time transmission ratio and the initial transmission ratio, and the updated floor data can be used for elevator leveling control. Specifically, the ratio of the real-time transmission ratio and the initial transmission ratio can be obtained. When the elevator control system obtains the floor data, the learned floor data of each floor can be multiplied by the ratio to update the floor data of each floor; that is, the floor number of each floor*Juse / J0 is used as the floor data of the elevator control system to participate in the elevator leveling control.

[0062] Based on the real-time transmission ratio and the initial transmission ratio, the floor data of each floor is updated to obtain the real floor data. The updated floor data is used for elevator leveling control, which can effectively avoid the elevator from being under-leveled or over-leveled.

[0063] It can be seen that in the embodiment of the present application, before the elevator is put into operation, the floor data of each floor and the initial transmission ratio between the traction wheel and the friction wheel of the encoder are recorded; after the elevator is put into operation, the current transmission ratio between the traction wheel and the friction wheel of the encoder is determined based on the target pulse number of the traction wheel and the pulse line number of the encoder, and the real-time transmission ratio is obtained by updating the current transmission ratio; the floor data of each floor is updated by the real-time transmission ratio and the initial transmission ratio, and the floor data of each floor can be accurately obtained even when the friction wheel of the encoder is worn; the updated floor data is used for elevator leveling control, which can avoid under-leveling or over-leveling of the elevator and ensure the normal operation of the elevator.

[0064] Further, the elevator control process will be described in detail below. Figure 2 As shown, the specific steps are as follows:

[0065] 201. Before the elevator is put into operation, record the floor data of each floor of the elevator shaft, the initial transmission ratio between the traction wheel and the friction wheel of the encoder, and the position pulse data of the upper and lower forced switches.

[0066] The elevator control system can record the floor data of each floor of the elevator shaft, the initial transmission ratio between the traction wheel and the friction wheel of the encoder, and the position pulse data of the upper and lower forced switches before the elevator is put into operation. Among them, recording the floor data of each floor of the elevator shaft and the initial transmission ratio between the traction wheel and the friction wheel of the encoder is similar to the above step 101, and the details are not repeated here.

[0067] The up and down forced switches are installed on the top and bottom floors of the elevator shaft, and are used to force the speed to be reduced from the normal rated speed to the set slow speed when the elevator reaches the top and bottom stations, so as to force the elevator to decelerate and stop slowly, thereby improving comfort and safety. The elevator control system can detect and record the position pulse data of the up and down forced switches of the elevator shaft based on the encoder. That is, the position pulse data of the up and down forced switches is learned and stored in the corresponding storage space.

[0068] 202. After the elevator is put into operation, based on the encoder, the number of pulses between multiple groups of two adjacent zero-position pulse signals in a single operation of the elevator is detected.

[0069] After the elevator is put into operation, the elevator control system can detect multiple pulse numbers between multiple groups of two adjacent zero-position pulse signals in a single operation of the elevator based on the encoder, wherein the single operation is a single operation process of the elevator from running to stopping. In a single operation, the encoder can detect multiple zero-position pulse signals, and multiple pulse numbers can be obtained by counting the number of pulses between two adjacent zero-position pulse signals.

[0070] Specifically, during the steady-speed operation of the elevator, the influence of the difference in the detection time of the zero-position pulse signal caused by the speed change can be ignored. The number of pulses between two zero-position pulse signals is counted, and the pulse numbers are stored in an array in order. The old pulse numbers in the array will be automatically overwritten. When the elevator stops, if the pulse numbers have been stored in the array positions, the data analysis of multiple pulse numbers in the array is performed.

[0071] 203. Determine a plurality of first pulse numbers within a preset deviation range from a plurality of pulse numbers to obtain a target pulse number of the traction sheave.

[0072] It is understandable that in order to avoid the detection error of the encoder and obtain the target pulse number of the traction wheel more accurately, multiple first pulse numbers within the preset deviation range can be determined from multiple pulse numbers to obtain the target pulse number of the traction wheel. Specifically, multiple first pulse numbers within the preset deviation range can be determined from multiple pulse numbers; wherein, the multiple pulse numbers can be summed and averaged, and the multiple pulse numbers and the average value can be detected to see whether they are within the preset deviation range, and the pulse numbers that are not within the preset deviation range are excluded to obtain multiple first pulse numbers; the preset deviation range can be a difference of a preset pulse number. Then, the multiple first pulse numbers can be arranged in size, the maximum value and the minimum value are removed, and the remaining first pulse numbers are averaged to obtain the target pulse number of the traction wheel.

[0073] 204. Determine a current transmission ratio between the traction wheel and the friction wheel of the encoder based on the target pulse number of the traction wheel and the pulse line number of the encoder.

[0074] It is understandable that step 204 is similar to the above step 103, and the details are not repeated here.

[0075] 205. Update the current transmission ratio based on the initial transmission ratio and the preset update weight to obtain a real-time transmission ratio.

[0076] The elevator control system can update the current transmission ratio based on the initial transmission ratio and the preset update weight to obtain the real-time transmission ratio; wherein the current transmission ratio can be passed through a low-pass filtering link and calculated with the real-time transmission ratio to obtain the updated real-time transmission ratio.

[0077] Specifically, the current transmission ratio can be updated based on the update formula: Juse = [(K-1)*Juse+Jnow] / K to obtain the real-time transmission ratio; wherein Juse is the real-time transmission ratio, and the initial value of Juse is the initial transmission ratio; Jnow is the current transmission ratio; and K is the preset update weight. It can be understood that the larger the value of K, the smaller the weight of the transmission ratio value corresponding to the currently calculated [(K-1)*Juse+Jnow], and the slower the update speed of the transmission ratio; the smaller the value of K, the larger the weight of the transmission ratio value corresponding to the currently calculated [(K-1)*Juse+Jnow], and the faster the update speed of the transmission ratio. For example, K = 4096, which means that the transmission value calculated for the current elevator operation accounts for 1 / 4096 of the updated value; the elevator runs 4096 times to completely update the transmission ratio. Taking into account the actual situation of the elevator: the elevator runs 600 times a day and about 4000 times a week, the complete transmission ratio will be updated once in the above week.

[0078] 206. Based on the real-time transmission ratio and the initial transmission ratio, update the floor data of each floor and the position pulse data of the up and down forced switches.

[0079] The elevator control system can update the floor data of each floor and the position pulse data of the upper and lower forced switches based on the real-time transmission ratio and the initial transmission ratio. Among them, the updating of the floor data of each floor based on the real-time transmission ratio and the initial transmission ratio is similar to the above-mentioned headquarters after 105, and the details are not repeated here. When the elevator control system obtains the position pulse data of the upper and lower forced switches, it will use the position pulse data *Juse / J0 of the upper and lower forced switches self-learned by the elevator shaft as the updated position pulse data of the upper and lower forced switches.

[0080] It can be seen that in the embodiment of the present application, the elevator control system can obtain the real floor data and the real position pulse data of the up and down forced switches to ensure the normal operation of the elevator.
