Technical Field

The invention relates to the technical field of elevators, in particular to a debugging method for an absolute position control system.

Background

The absolute position system is a set of devices which are arranged in an elevator shaft, continuously encode the shaft position by using a belt, read the belt code in real time by using a safety box and send data to an elevator controller in a communication mode. The data shows that the current absolute position system, the more typical technical scheme comprises: the scheme of using the magnetic grid ruler is characterized in that the magnetic grid ruler is not easily influenced by illumination, temperature and abrasion; the scheme of using the two-dimensional code is easily influenced by illumination and uses a punching scheme, and the belt is slightly worn, so that the identification precision and efficiency are influenced.

The absolute position system has very obvious use characteristics in the elevator, but the elevator provided with the absolute position control system on the market is too complicated to debug, wastes time and labor, has high debugging experience requirements on debugging personnel, generally needs the debugging personnel with rich experience to be sufficient, and therefore, the debugging cost and efficiency are difficult to ensure.

The existing methods for debugging the absolute position control system in the market mainly comprise the following two methods:

manual self-learning without adding a magnetic switch and a magnet: the specific implementation method comprises the following steps: the method is characterized in that the upper reference position and the lower reference position of the magnetic stripe are firstly determined, then one person backs up the elevator in the car, and meanwhile, in order to ensure the precision of the calibrated flat layer, one person is needed to be in the car, two persons are matched with each layer of position needing to be stopped to calibrate the flat layer position of each layer of elevator, so that the method at least needs two persons to be matched, and is particularly directed at high-rise elevators, trouble and labor are wasted, and the method is not easy to popularize generally.

The method comprises the following steps of adding a magnetic switch and a magnetic stripe on a hall car door sill in a semi-automatic self-learning mode: because of the defects of the first mode, the second method is commonly used for high-rise elevators on the market, and has the advantages that a magnet and a magnetic switch for identifying the leveling position are additionally arranged at the door opening position of each leveling layer, so that the working time of calibrating each leveling position by matching two persons in the first method can be saved, but more installation working hours and material cost are increased, because the method needs to install a magnet (magnetic strip) on each floor of landing door sill and a magnetic switch on the landing door sill, more material cost and installation working hours are increased, the method is contrary to the use of an absolute position control system and is to simplify the switches, cancel all photoelectricity (magnetic switches/magnetic strips) comprising leveling switches, strong level reducing switches, maintenance limit switches and limit switches, and save the cost, the working hours are saved. This method also has the drawback that the position of the installed magnet and magnetic switch also needs to be very accurate in order to ensure the accuracy of the calibrated flat layer.

Chinese patent document CN108275529A discloses an "elevator position detection device and a leveling control method". The method adopts a detection device and an operator which are in communication connection with each other; the detection device comprises a three-axis inertial sensor, a data processor and an interface circuit; the three-axis inertial sensor comprises a three-axis accelerometer and a three-axis gyroscope; the three-axis accelerometer is used for detecting the acceleration of the lift car during the operation of the elevator, and the three-axis gyroscope is used for detecting the angular velocity of the lift car during the operation of the elevator; the data processor is connected with the three-axis inertial sensor and the interface circuit; the data processor receives three-dimensional elevator operation data of the three-axis inertial sensor, calculates the current absolute position and the operation speed of the elevator car, and transmits the current absolute position and the operation speed to the elevator main controller through the interface circuit; the interface circuit is used for communication between the data processor and the elevator main controller and between the data processor and the operator. Above-mentioned technical scheme increases auxiliary assembly and realizes that elevator position detects has increased working cost and has not effectively improved elevator absolute position debugging efficiency.

The technical problem of the invention is mainly solved by the following technical scheme: the invention comprises the following steps:

s1 calibrating the up and down reference positions of the elevator; DOWNRef is a reference position for calibrating the magnetic grating ruler, and means an initial point for calibrating data of a well of the magnetic grating ruler: generally, the position of the bottom leveling layer of the elevator is 150mm downwards, UP Ref is the magnetic grid ruler calibration upper reference position, and the meaning is the ending position of the magnetic grid ruler well data calibration: generally, the elevator is arranged at the position of 150mm above the flat floor of the top floor, and the distance design can be changed so as to meet the distance requirements of different manufacturers at different elevator speeds.

S2, setting the distance between the buildings;

s3 the elevator performs self-learning operation;

s4 is adjusted for flat layer accuracy.

Preferably, in step S1, DOWN Ref is calibrated to be a magnetic grid ruler lower reference position, UP Ref is calibrated to be a magnetic grid ruler upper reference position, the magnetic grid ruler lower reference position is a position of a limit distance below a bottom flat layer of the elevator, the magnetic grid ruler upper reference position is a position of a limit distance above a top flat layer of the elevator, a position of a protection distance above the magnetic grid ruler lower reference position is calibrated to be a lower limit position of the elevator, and the magnetic grid ruler lower protection distance is calibrated to be a position of a lower limit position of the elevator. The lower reference position is generally the position of 150mm down for the flat bed position of elevator bottom layer, and the upper reference position is generally the position of 150mm up for the flat bed position of elevator top layer, and the lower extreme position of elevator is acquiescently the flat bed position of elevator bottom layer and is 100mm down, and the upper extreme position of elevator is acquiescently the flat bed position of elevator top layer and is 100mm up.

Preferably, when the inter-floor distance is set in step S2, the inter-floor distance between the bottom floor level and the level floor above the bottom floor level is defined as the number 00, the number of the remaining inter-floor distances is sequentially increased by 1, and when the inter-floor distance of the number 00 is set, the remaining inter-floor distance is automatically equal to the inter-floor distance of the number 00, and then when the other inter-floor distances are set, only the inter-floor distance of the user is changed without affecting the remaining inter-floor distances. The residual floor space changes along with the floor space value of the serial number 00, the setting complexity is reduced, the parameter setting time is saved when the floor heights are consistent, and the residual floor space can be independently set and randomly changed without influencing each other when the floor space of the floors except the serial number 00 is set.

Preferably, after the step S3 is completed, the elevator starts self-learning, runs from the bottom floor to the top floor at a set self-learning speed, and automatically calibrates the leveling floor at each leveling floor position according to the set leveling floor height. The self-learning of the express train of the elevator is completed when the operation of the step S3 is completed, and the elevator can run normally, but since the floor height of each floor has a partial error range, the next floor leveling precision adjustment function may be needed.

If a layer is deviated 15mm upwards, then key-in 30015+ ENTER means downward adjustment for 15mm, if it is deviated 10mm downwards, then key-in 10+ ENTER means upward adjustment for 10mm, and the single maximum adjustment value is 30000mm (30 meters).

Preferably, after the adjustment of the leveling position is completed, when the elevator runs in the whole course again, the leveling position is automatically corrected and calibrated and stored when the elevator passes through the set position according to the set parameter value after the leveling modification. The elevator does not need to be manually driven to a required calibration position for calibration, so that the working hours are greatly saved, the adjustment range of single leveling precision is 30 meters, and the light within the range can meet various building error ranges.

Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

Example (b): a debugging method for an absolute position control system in this embodiment, as shown in fig. 1, includes the following steps:

s1 calibrating the up and down reference positions of the elevator. The calibration method comprises the steps of calibrating a DOWN Ref as a magnetic grid ruler to calibrate a lower reference position, calibrating an UP Ref as a magnetic grid ruler to calibrate an upper reference position, calibrating the lower reference position of the magnetic grid ruler to be a limit distance position below a bottom flat layer of an elevator, calibrating the upper reference position of the magnetic grid ruler to be a limit distance position above a top flat layer of the elevator, calibrating a lower limit position of the elevator at a protection distance position above the lower reference position of the magnetic grid ruler, and calibrating a lower limit position of the elevator at a protection distance position below the upper reference position of the magnetic grid ruler.

In fig. 2, reference numeral 1 denotes DOWN Ref as a reference position for magnetic scale calibration, which means a starting point of magnetic scale well data calibration: generally 150mm down from the bottom floor level position of the elevator (the distance design can be changed so as to meet the distance requirements of different manufacturers at different elevator speeds). And 2, the lower limit position of the elevator is set as the default of the position of the elevator at the bottom floor level, which is 100mm downward (the distance design can be changed so as to meet the distance requirements of different manufacturers at different elevator speeds). And 3 is the bottom flat layer position. And 4 is the sub-bottom flat position. And 5 is the next-to-top flat position. And 6 is the top flat position. And 7 is the upper limit position of the elevator, which is the default position of 100mm upwards from the top floor leveling position of the elevator (the distance design can be changed so as to meet the distance requirements of different manufacturers at different elevator speeds). And 8, UP Ref is used as the upper reference position of the magnetic grid ruler calibration, and the meaning is the end position of the magnetic grid ruler well data calibration: generally 150mm above the top floor level of the elevator (the distance design can be changed to meet the distance requirements of different manufacturers at different elevator speeds).

S2, setting the distance between the buildings; firstly, defining the inter-floor distance between the flat floor at the bottom layer and the flat floor at the upper layer at the bottom layer as the serial number 00, sequentially adding 1 to the serial numbers of the rest inter-floor distances, automatically enabling the rest inter-floor distances to be equal to the inter-floor distances of the serial number 00 when the inter-floor distance of the serial number 00 is set, and only changing the inter-floor distances of the self-floor when other inter-floor distances are set without influencing the rest inter-floor distances. The residual floor space changes along with the floor space value of the serial number 00, the setting complexity is reduced, the parameter setting time is saved when the floor heights are consistent, and the residual floor space can be independently set and randomly changed without influencing each other when the floor space of the floors except the serial number 00 is set.

S3 the elevator performs a self-learning operation. After the inter-floor distance is set, entering a self-learning menu, inputting a self-learning command, starting self-learning of the elevator, running from the bottom to the top at a set self-learning speed, and automatically calibrating the leveling at each level according to the set level.

Note that: the automatic calibration point of the bottom flat layer is DOWN Ref, the lower reference position is 150mm upwards, and the parameter is adjustable so as to be suitable for various elevator speed requirements; when the third step of operation is executed, the self-learning of the express train of the elevator is finished, the elevator can run normally at the moment, but because the floor height of each floor of the building has a partial error range, the next leveling precision adjusting function may be needed.

S4 adjusts for the flat layer accuracy. When the elevator runs to the door opening area of each floor, the error of the floor leveling is converted into a fine adjustment numerical value to be recorded, and after the recording is finished, the elevator enters a leveling precision adjustment menu, adjusts the position of the floor leveling and stores the position. If a layer is deviated 15mm upwards, then key-in 30015+ ENTER means downward adjustment for 15mm, if it is deviated 10mm downwards, then key-in 10+ ENTER means upward adjustment for 10mm, and the single maximum adjustment value is 30000mm (30 meters). And after the parameter adjustment is finished, exiting the menu, and automatically saving the system. After the adjustment of the leveling position is completed, when the elevator runs in the whole course again, the leveling position is automatically corrected and calibrated and stored when the elevator passes through the set position according to the set parameter value after the leveling modification. The elevator does not need to be manually driven to a required calibration position for calibration, so that the working hours are greatly saved, the adjustment range of single leveling precision is 30 meters, and the light within the range can meet various building error ranges.
