[0044] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0045] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] This invention measures the movement of moving parts in a time dimension and sets the analog reading range according to the actual situation to eliminate the error caused by electronic ruler drift and make the reading more accurate.

[0047] This invention provides an electronic ruler anti-interference precise positioning method, device, equipment, and storage medium, which are described below.

[0048] Combination Figure 1 As shown, a specific embodiment of the present invention discloses an anti-interference and precise positioning method for an electronic ruler, applied to a moving component connected to the electronic ruler, comprising:

[0049] S101. Obtain the standard running time and standard analog quantity, wherein the standard running time is the time required for the moving part to run to the target position under no-interference conditions, and the standard analog quantity is the analog quantity of the electronic ruler when the moving part is located at the target position under no-interference conditions;

[0050] S102. Obtain the actual process parameters, and based on the actual process parameters and the standard running time, obtain the analog quantity reading time interval;

[0051] S103. Obtain the actual running time and actual analog quantity of the moving parts;

[0052] S104. Based on the inclusion relationship between the actual running time and the analog quantity reading time interval, and based on the standard analog quantity and the actual analog quantity, the positioning result is obtained.

[0053] This invention provides an anti-interference and precise positioning method, apparatus, device, and storage medium for electronic rulers. The method first acquires the standard operating time and standard analog quantity under interference-free conditions. Then, it sets an analog quantity reading time interval based on actual process parameters. During actual production, readings are taken within this analog quantity reading time interval. Specifically, based on the inclusion relationship between the actual operating time and the analog quantity reading time interval, and using the standard analog quantity and the actual analog quantity, the positioning result is obtained. Compared to existing technologies, this invention utilizes the time dimension to measure the movement of moving parts. The analog quantity reading time interval reflects the time required for the moving part to reach the target position and has a certain margin, ensuring that even if the readings within the analog quantity reading time interval are in a drift state, the error is acceptable. This eliminates the adverse effects of interference on the electronic ruler and solves the problem of inaccurate readings caused by drift.

[0054] In a preferred embodiment, step S101, obtaining the standard running time and standard analog quantity, specifically includes:

[0055] Set a timer on the moving part. The accuracy of the timer can be selected according to the actual positioning accuracy, such as 100ms, 10ms, etc. Then set the positioning offset of the electronic ruler (the corresponding analog value of the conversion process).

[0056] In non-production mode, adjust the electronic ruler to the origin position and the moving part to its initial position as well. Then, run the moving part and the electronic ruler and start the timer. The electronic ruler will reach the offset of the moving part at the target position, and the timer value at this point will be recorded. The analog signal of the electronic ruler at this time is the standard analog signal, and the timer value at this point is the standard running time.

[0057] Then, the analog signal reading time interval can be set, i.e., step S102 is executed. As a preferred embodiment, step S102 in this embodiment, obtaining the actual process parameters and obtaining the analog signal reading time interval based on the actual process parameters and the standard running time, specifically includes:

[0058] Obtain the actual process parameters, including the positioning allowable error;

[0059] The analog quantity reading time interval is obtained based on the positioning allowable error and the standard running time.

[0060] Specifically, in a preferred embodiment, the above steps, based on the positioning allowable error and the standard running time, determine the analog quantity reading time interval, specifically including:

[0061] The offset time is obtained based on the positioning allowable error.

[0062] The analog quantity reading time interval is obtained based on the offset time and the standard running time.

[0063] Furthermore, in a preferred embodiment, the actual process parameters in the above steps also include timer accuracy and the traveling speed of the moving parts. The step of obtaining the offset time based on the positioning allowable error specifically includes:

[0064] The offset coefficient is obtained based on the timer accuracy, the component travel speed, and the positioning allowable error;

[0065] The offset time is obtained based on the offset coefficient, the timer accuracy, and the positioning allowable error, wherein the product of the offset time and the traveling speed of the moving part is less than the positioning allowable error.

[0066] The following is a more detailed embodiment to illustrate step S102 above:

[0067] First, the actual process parameters are obtained. In this embodiment, the allowable error for the movement of the moving parts is 1cm (i.e., the allowable positioning error). The timer accuracy is selected as 0.1 seconds resolution (the reading accuracy of the S7200 timer T02). Of course, in practice, it can also be adjusted to 0.01 seconds, etc., as needed. In this embodiment, the traveling speed of the moving parts is 2mm / s.

[0068] In this embodiment, the offset coefficient is set to 10 (in practice, it can be flexibly adjusted according to specific needs), so the offset time is 10 × 0.1, which is 1 second. The offset time can be the allowable time for deviation. Assuming that the standard running time for the moving part to reach the target position is 10 seconds, then by adjusting the standard running time according to the offset time, the analog reading time range of 10 ± 1 seconds, which is 9 to 11 seconds, can be obtained.

[0069] Based on the product of the moving part's speed and offset time, it can be seen that under normal movement, the displacement deviation within the analog reading time interval is at most ±2mm, less than the allowable positioning error of 1cm. Therefore, when reading the electronic ruler within the analog reading time interval, as long as the actual analog value of the electronic ruler equals the standard analog value, it can be considered that the moving part has reached the target position. This is because even if the electronic ruler drifts, the error between the actual position of the moving part and the target position will only be no more than 2mm, far less than 1cm, which is acceptable.

[0070] Furthermore, as a preferred embodiment, the actual running time and actual analog quantity in step S103 of this embodiment are the actual display time of the timer and the actual analog quantity reading of the electronic ruler under actual production conditions (when the electronic ruler is subject to interference).

[0071] Combination Figure 2 As shown, in a preferred embodiment, step S104 of this embodiment, obtaining the positioning result based on the inclusion relationship between the actual running time and the analog quantity reading time interval, and based on the standard analog quantity and the actual analog quantity, specifically includes:

[0072] Determine whether the actual running time is within the analog signal reading time interval;

[0073] If yes, the positioning result is obtained based on the actual analog quantity and the standard analog quantity; otherwise, the positioning result is obtained based on the numerical comparison between the actual running time and the upper limit of the analog quantity reading time interval.

[0074] Specifically, in a preferred embodiment, obtaining the positioning result based on the actual analog quantity and the standard analog quantity includes:

[0075] Determine whether the actual analog quantity and the standard analog quantity are consistent;

[0076] If yes, the positioning result of the moving part at the target position is obtained; if no, the moving part is driven to continue moving, and the actual running time and actual analog quantity of the moving part are obtained again.

[0077] In the above process, the actual running time falls within the analog signal reading time interval. If a position is found where the actual analog signal and the standard analog signal values ​​match within the analog signal reading time interval, then it can be considered that the moving part has reached the target position. Even if the electronic ruler drifts, the resulting positioning error is within an acceptable range. If not, the moving part continues to move and the process is repeated. The above process can be repeated during actual production as the moving part moves, that is, steps S103 and S104 are repeatedly executed until it is determined that the moving part has reached the target position.

[0078] Specifically, in a preferred embodiment, obtaining the positioning result based on the numerical comparison between the actual running time and the upper limit of the analog signal reading time interval specifically includes:

[0079] Determine whether the value of the actual running time is greater than the upper limit of the analog quantity reading time interval;

[0080] If yes, the positioning result of the moving part at the target position is obtained; if no, the moving part is driven to continue moving, and the actual running time and actual analog quantity of the moving part are obtained again.

[0081] In the above process, if the actual running time is outside the analog reading time interval, and the actual running time is less than the analog reading time interval, it can be assumed that the moving part has not yet reached the vicinity of the target position. In this case, the moving part can continue to run, and steps S103 and S104 can be repeated in subsequent processes. If the actual running time exceeds the analog reading time interval (i.e., the actual running time exceeds the upper limit of the analog reading time interval), it indicates that a position where the actual analog value and the standard analog value are consistent cannot be found within the entire analog reading time interval. In this case, the drift of the electronic ruler has a significant impact on the reading, and its analog value can no longer reflect the actual situation. At this time, the position of the moving part is measured based on time. If the actual running time exceeds the upper limit of the analog reading time interval, it indicates that the moving part has reached the vicinity of the target position, and its error is within an acceptable range.
