Referring to fig. 1, an embodiment of the present invention provides a calibration method for an elevator, where the calibration method includes:
s10), in an initial state, acquiring the initial pulse number of the current building, and detecting the length of a preset device in an elevator shaft to acquire a first detection pulse number;
s20), acquiring preset calibration time, and detecting the length of the preset device within the preset calibration time to obtain a second detection pulse number;
s30) calibrating the initial pulse number based on the first detected pulse number and the second detected pulse number, obtaining a calibrated pulse number.
In a possible implementation mode, a magnetic isolation plate is installed in an elevator shaft as a preset device, and a corresponding electromagnetic sensor is configured on an elevator car. In the running process of the elevator, the electromagnetic sensor passes through the magnetic isolation plate on each floor to obtain a corresponding pulse signal, and the elevator control system obtains the floor height information of each floor based on the pulse signal. In order to facilitate automatic calibration in the subsequent operation process, in the initial state of the elevator, for example, after the installation and debugging of the elevator are completed, the initial pulse number of the current building is obtained, and the length of the magnetic isolation plate of each floor is detected, so that the corresponding first detection length is obtained.
After the initialized information is obtained, a preset calibration time is further obtained, for example, in the embodiment of the present invention, a technician sets the preset calibration time required to perform the calibration operation in the elevator control system, and at this time, the elevator control system performs the calibration operation according to the preset calibration time.
The elevator control system controls the elevator car to run up and down in the hoistway, and in the running process, the elevator control system acquires a pulse signal obtained by detecting the length of the magnetic isolation plate in real time and further acquires a corresponding second detection pulse number.
In the embodiment of the invention, the initial pulse number with accurate floor information is obtained in advance on the basis of normal operation of the elevator, and the elevator can be automatically calibrated according to the preset time period and the calibratable time in the subsequent elevator operation process, so that the floor information stored in an elevator control system is timely adjusted and optimized, the elevator can have accurate control capability under the condition of long-time operation, the user experience is improved, and the use safety of the elevator is ensured.
In an embodiment of the present invention, the acquiring the initial pulse number of the current building includes: under the condition that the elevator runs for the first time, controlling the elevator to run in the elevator shaft according to a preset running speed; sequentially acquiring the floor pulse number of each floor of the current building; and obtaining the initial pulse number of the current building based on the floor pulse number.
In a possible embodiment, in order to facilitate automatic calibration of the floor height information of the elevator during subsequent use, therefore, during the first operation of the elevator, a floor height self-learning operation is performed on the floor of the current building, for example, a technician may send a floor height self-learning instruction to the elevator control system, the elevator control system controls the elevator to move slowly from the bottom of the hoistway to the top along the guide rail according to a preset operation speed, for example, in the embodiment of the present invention, in order to ensure the accuracy of data collected during the operation process and avoid the data accuracy deficiency caused by the overhigh operation speed, the elevator is controlled to move in the elevator hoistway according to the speed of 0.5m/s, and during the movement process, the pulse information of each floor is obtained through the electromagnetic sensor and the magnetic isolation plate of each floor, so as to obtain the number of pulses of the floor corresponding to each floor, then according to the floor number of the current building, and acquiring the initial pulse number of the current building, and storing the initial pulse number, wherein the accurate height information of each floor is acquired at the moment.
Referring to fig. 2, in the embodiment of the present invention, the obtaining the preset calibration time includes:
s201) acquiring a preset time period;
s202) judging whether a preset calibration time period is obtained or not;
s2031) generating the preset calibration time based on the preset time period and the preset calibration time period under the condition of obtaining the preset calibration time period;
s2032) under the condition that the preset calibration time period is not acquired, acquiring a calibratable time period, and generating the preset calibration time based on the calibratable time period and the preset time period.
In a possible implementation, before starting calibration of the elevator floors, a preset time period is first obtained, for example, a technician may set a corresponding preset time period for the current elevator according to parameters such as elevator type, elevator load, and elevator wear speed, for example, in an embodiment of the present invention, the preset time period may be set to be calibrated once per month. Then, the elevator control system further determines whether a preset calibration period is obtained, for example, in the embodiment of the present invention, a technician may set a preset calibration period that can be calibrated according to a specific use condition of the current building, for example, for an office building, the preset calibration period may be 12 pm to 6 am, and for a residential district, the preset calibration period may be 3 am to 6 am. In the embodiment of the invention, the elevator control system monitors whether the next calibration operation needs to be executed according to the preset time period and the preset calibration time period in real time after the last automatic calibration is completed or the elevator control system runs for the first time, and controls the elevator to execute the calibration operation if the current time needs to reach the time when the next calibration operation needs to be executed.
In the embodiment of the invention, the specific preset calibration time capable of being calibrated is determined according to the actual service time of the elevator, so that the accurate calibration of the elevator floor information can be realized under the condition of not causing any influence on users, the elevator leveling accuracy is effectively ensured, and the safety of the elevator in the service process is improved.
Referring to fig. 3, in an embodiment of the present invention, the calibrating the initial pulse number based on the first detected pulse number and the second detected pulse number to obtain a calibrated pulse number includes:
s301) obtaining a calibration coefficient based on the first and second numbers of detected pulses;
s302) calibrating the initial pulse number based on the calibration coefficient to obtain the calibrated pulse number.
Further, in an embodiment of the present invention, a preset device is provided on each floor of a current building, and the obtaining a calibration coefficient based on the first number of detected pulses and the second number of detected pulses includes: acquiring the ratio of the first detection pulse number to the second detection pulse number corresponding to each floor in sequence; generating deviation trend information of the current building based on the ratio; generating the calibration coefficient based on the deviation trend information.
In a possible implementation, after the preset calibration time is obtained, the calibration operation is performed according to the preset calibration time. In the embodiment of the invention, the elevator control system firstly determines that no passenger is in the current elevator car, for example, the elevator car can be controlled to slowly move up and down in the shaft by playing corresponding prompt information, remotely driving away the elevator car by a technician or closing the elevator car for 10 minutes and switching the elevator state into the maintenance state, and the like, for example, the elevator car can be firstly moved to the bottom of the shaft, then the elevator car is controlled to slowly move upwards, the length of the magnetism isolating plate of each floor is detected by the electromagnetic sensor in the moving process, the corresponding second detection pulse number is obtained, and the elevator car is controlled to stop moving after the elevator car is moved to the top of the shaft or the highest floor.
At this moment, the elevator control system firstly compares the first detection pulse number and the second detection pulse number of each floor to obtain the difference of detecting the length of the magnetic isolation plate of each floor, because the length of the magnetic isolation plate is practically unchanged, the difference actually corresponds to the abrasion condition of a traction machine wheel groove or a steel wire rope, a corresponding calibration coefficient can be generated according to the difference, for example, the ratio of the first detection pulse number and the second detection pulse number of each floor is sequentially obtained, the deviation trend of the lower-layer high information influenced by abrasion can be further obtained according to the ratio, for example, a ratio change curve is drawn according to the mapping relation between the floors and the ratio, and the ratio change curve is used as the deviation trend information of the current building. Of course, the skilled person may also directly calibrate the initial pulse number by directly using the ratio of the first detected pulse number to the second detected pulse number as a calibration coefficient, so as to obtain the calibrated pulse number. At this time, linear or non-linear fitting is performed according to the ratio change curve, so as to obtain a corresponding calibration coefficient.
At this time, the initial pulse number is calibrated according to the calibration coefficient, for example, in the embodiment of the present invention, the initial pulse number may be multiplied or divided by the calibration coefficient, so that an accurate pulse number value of each floor corresponding to the accurate floor leveling of the current building may be obtained, that is, an accurate calibrated pulse number is obtained.
In the embodiment of the invention, the elevator is controlled to execute the corresponding automatic calibration operation at the idle running time of the elevator by utilizing the existing sensor and related components in the elevator control system, so that the leveling information of the elevator control system is calibrated, whether the current tractor wheel groove or the steel wire rope has safety threat or not can be analyzed according to the pulse data, and corresponding safety measures such as the replacement of the steel wire rope and the like can be taken in time, so that the safety of the elevator in the using process is effectively improved, and the user experience is improved.
