That is, these functional entities can be implemented in software form, or in one or more hardware charging modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0023] As a representative of logistics handling vehicles, forklifts play an important role in the logistics system of enterprises. In the process of fast and accurate delivery of goods, safety and efficiency are key factors throughout the entire process. When the aisles in the logistics warehouse are narrow and the forklift is large, it is difficult to adjust the position during the transportation of goods. Therefore, the lateral movement function of the smart electric forklift provides greater convenience for forklift operation. However, it also poses challenges to the "flexibility" of the fork and its displacement positioning control - due to the limitations of the sensor installation space and the sensing distance of the target object, it is necessary to consider a sensor with a suitable shape and reliably detect the displacement, and choose a position with a low vibration amplitude for the equipment for installation. The use of sensors can accurately control the lateral displacement of the fork, with a displacement control accuracy of 1mm, without adjusting the position of the entire vehicle.

[0024] In the related art, the internal circuit of the sensor is composed of multiple groups of independent inductor coil circuits. However, due to the differences between the inductor coils and components in each group of circuits, there may be a large deviation between the position information output by the sensor and the actual position in actual applications, and the position information output by each sensor at the same position may also have a large deviation.

[0025] To this end, the present invention provides a method, system, device and medium for improving the accuracy of a positioning sensor, and a method for performing compensation processing through the coordinated operation of a sensor, a host computer and a motor, thereby improving the accuracy of the sensor.

[0026] like Figure 1 As shown, Figure 1 A method for improving the accuracy of a positioning sensor provided by an embodiment of the present invention comprises the following steps: S100, obtaining a measuring range of a sensor, and dividing the measuring range into a plurality of position points; wherein the sensor is an inductive positioning sensor; S200, controlling the sensor to send a displacement command containing a position point to a host computer, so that the host computer controls the motor to drive the object to be measured to move to each position point; S300, obtaining position information measured by the sensor at each position point, and recording the position points and the measured position information in a one-to-one correspondence to obtain a correspondence table; S400, calibrating the distance value measured by the sensor within the measuring range based on the corresponding table to obtain the distance value after accuracy compensation.

[0027] In the embodiment provided by the present invention, the range of the sensor is first determined, and the range is divided into a plurality of position points. This helps to perform detailed testing and calibration of the accuracy of the sensor in subsequent steps. By sending a displacement command to the host computer, the motor is controlled to move the object to be measured to these preset position points. The host computer is respectively connected to the sensor and the motor for communication, and is responsible for receiving the instructions of the sensor and driving the motor. At each position point, the sensor measures and records the position information. This information will correspond to the corresponding position points one by one, and form a corresponding table, which is the basis for subsequent calibration work. In some embodiments, the sensor includes a single-chip microcomputer, and the established corresponding table is recorded in the flash of the single-chip microcomputer. Using the corresponding table, the distance value measured by the sensor within the range is calibrated. In this way, the reading of the sensor can be adjusted to compensate for possible errors, thereby improving the accuracy of the measurement. The present invention can significantly improve the measurement accuracy of the inductive positioning sensor through precise control and calibration.

[0028] In some embodiments, in S100, the obtaining of the range of the sensor and dividing the range into a plurality of position points includes: S110, obtaining the range and resolution of the sensor; Specifically, the maximum and minimum measurement values ​​of the sensor are determined according to its specifications to obtain the working range of the sensor. According to the specific needs of the application, the required measurement accuracy and resolution are determined, so as to determine the number and distribution of the position points in the subsequent steps.

[0029] S120, determining a position interval based on the resolution and the range, and setting a plurality of position points within the range according to the position interval.

[0030] Specifically, the position intervals may be equidistant, or more densely spaced points may be set in certain areas as required, and each position point corresponds to a specific value within the sensor range.

[0031] In some embodiments, in S200, the control sensor sends a displacement command containing a position point to a host computer, so that the host computer controls a motor to drive the object to be measured to move to each position point, including: S210, a communication connection is established between the sensor and the host computer, and the sensor sends a displacement command to the host computer through the established communication connection; wherein the displacement command includes a distance, direction and speed of the displacement; Specifically, the sensor formats the position point into a command format that can be recognized by the host computer, and the command format includes the distance, direction and speed of the displacement; before sending the command, the sensor performs internal verification to ensure that all parameters are within the predetermined range. A stable communication connection is established between the sensor and the host computer to ensure the reliability of data transmission. The sensor sends the displacement command to the host computer through the established communication connection.

[0032] S220, the host computer generates a corresponding motor control signal according to the received displacement command, and controls the motor to operate based on the motor control signal to drive the object to be measured to move; Specifically, after receiving the command, the host computer returns a confirmation signal to the sensor, indicating that the command has been successfully received. The host computer generates a corresponding motor control signal based on the received displacement command to control the motor to move the object under test.

[0033] S230, during the movement of the object to be measured, the host computer monitors the operating status of the motor and the position of the object to be measured in real time, and controls the motor to drive each position point reached by the object to be measured under normal operating conditions.

[0034] Specifically, during the movement of the object under test, the host computer monitors the running status of the motor and the position of the object under test in real time, and makes dynamic adjustments when necessary to ensure that the target position is reached accurately. The host computer records each position point reached by the object under test and the corresponding timestamp.

[0035] In some embodiments, in S300, the acquiring of the position information measured by the sensor at each position point, and recording the position points and the measured position information in a one-to-one correspondence to obtain a correspondence table include: S310, when the object to be measured reaches each position point, the sensor measures and records the current position information; Specifically, the position information measured at each position point reached by the measured object is recorded; the position information includes the position coordinates and the measurement timestamp.

[0036] S320, verifying the recorded location information, and storing the verified location information in a data structure; Specifically, the recorded position information is verified to ensure the accuracy and completeness of the data and exclude possible outliers or errors. The measured position information is stored in an appropriate data structure, such as an array, list, or database, for subsequent processing and analysis.

[0037] S330, associating each location point with its corresponding location information to form a correspondence table.

[0038] In some embodiments, in S320, verifying the recorded location information includes: S321, for each location point recorded in the corresponding table, obtaining location information obtained by multiple measurements of the location point; S322, determining the measurement deviation of multiple pieces of position information measured at the position point, and if it is determined that the measurement deviation is within the measurement deviation range, taking the average value of the multiple pieces of position information as the position information that has passed the verification.

[0039] In this embodiment, the recorded location information is verified in order to ensure the accuracy and reliability of the location information. Specifically, multiple independent measurements are performed for each location point recorded in the database or the corresponding table, thereby collecting sufficient data to evaluate the consistency and accuracy of the location information. For each location point, the deviation between the location information obtained by multiple measurements is calculated. An acceptable measurement deviation range is determined, and the measurement deviation range is based on the accuracy of the equipment, the measurement environment, and the application requirements. If the measurement deviation is within the acceptable measurement deviation range, it means that the multiple measurement results are consistent, and the measurement of the location point can be considered to be reliable. The average value of these reliable measurement values ​​is calculated as the location information that has passed the verification. This ensures the accuracy and reliability of the location information.

[0040] In some embodiments, the method further comprises: Determine whether the deviation value of each position point in the corresponding table exceeds a predetermined range, and remeasure the position points that exceed the predetermined range until the deviation values ​​of each position point in the corresponding table are within the predetermined range; wherein the deviation value is the difference between the position information measured at the position point and the actual position.

[0041] Specifically, the data in the corresponding table is analyzed to detect any possible anomalies or deviations, such as position deviations exceeding a predetermined range. If anomalies or deviations are detected, the position information measured at each position point is verified to improve data quality, providing a solid foundation for subsequent data analysis and calibration.

[0042] In some embodiments, in S400, calibrating the distance value measured by the sensor within the measuring range based on the corresponding table to obtain the distance value after accuracy compensation includes: S410, obtaining a distance value measured by the sensor within a measuring range; S420, determining the position information corresponding to the distance value in the corresponding table, and using the position information as the distance value after accuracy compensation.

[0043] In the embodiment provided by the present invention, the measuring range of the sensor is divided into a plurality of small position points, and then the sensor is connected to a host computer to send a series of commands to the host computer. After the host computer controls the motor to drive the object to be measured to move to each position point one by one, the sensor records the measured position information and the corresponding position points. At this time, the sensor can obtain a comparison table of the measured position information and the corresponding position points, and write the comparison table into the flash of the microcontroller inside the sensor. Thereafter, the sensor can find the precise value corresponding to the measured position information according to the comparison table in the flash of the microcontroller and output it, thereby improving the positioning accuracy of the sensor.
