[0002] Automobiles are playing an increasingly important role in modern life, and the number of automobiles in cities is also increasing. However, with the development of cities, more and more parking lots are needed. Generally, parking lots need to be set up in communities, office buildings and shopping malls to meet the needs of society. In order to regulate traffic, barriers are set up at the entrances and exits of parking lots. During use, the barriers are prone to position deviation, such as the bars on the barrier being tilted after multiple passages, which not only affects the appearance, but also increases wear and tear, affecting the service life of the barrier. Therefore, the barrier is often position calibrated or regularly position calibrated to correct or prevent the bars from being tilted. However, in the prior art, the position calibration of the barrier is completed manually, which not only hinders the normal use of the parking lot, but also increases the maintenance cost.

DETAILED DESCRIPTION

[0038] In order to make the objectives, technical solutions and beneficial technical effects of the present application more clear and obvious, the following will further describe the present application in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described in the present specification are only for explaining the present application, and are not intended to limit the present application.

[0039] ​It should also be understood that the terms used in the present application specification are only for the purpose of describing particular embodiments and are not intended to limit the present application. As used in the present application specification and the appended claims, "a", "an", and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0040] It should be further understood that the term "and / or" used in the present application specification and the appended claims means one or more of the associated listed items and all possible combinations thereof, and includes these combinations.

[0041] In the embodiments of the present application, the first aspect is to provide a barrier lifting position self-calibration method, so that the barrier can automatically calibrate the position.

[0042] As shown in Figure 1 The barrier lifting position self-calibration method comprises the following steps:

[0043] Calculate the lifting times of the barrier;

[0044] When the lifting times reach the calibration lifting threshold, start the position calibration;

[0045] Recalculate the lifting times after the position calibration is completed.

[0046] In the embodiments, the barrier is converted between the raised state and the fallen state by rotating when in use, and when pedestrians or vehicles want to pass through the barrier, the barrier is first raised to the raised state to let the pedestrians or vehicles pass through, and then lowered to the fallen state to close the passage. In this process, due to mechanical errors or control errors, the barrier will produce a certain position deviation in each lifting process, and the size of the position deviation will gradually accumulate with the increase of the lifting times. Therefore, whether the position deviation of the barrier reaches the degree that needs to be calibrated can be judged by the lifting times of the barrier, so that the size of the position deviation does not need to be measured before the barrier is calibrated, thereby facilitating the barrier to realize automatic position calibration.

[0047] At the same time, by calculating the lifting times of the barrier to determine whether the barrier needs to be calibrated, it can also avoid calibrating the position after the barrier has a large deviation, such as avoiding discovering that the barrier needs to be calibrated after it has a significant raised position abnormality or a significant fallen position abnormality. In this way, the barrier can always be in the best working state, and the mechanical loss caused by the large position deviation of the barrier can be reduced, thereby facilitating to improve the service life of the barrier.

[0048] Specifically, after the barrier gate is enabled, the start position and the end position of the barrier gate are first determined, the start position is used to determine that the barrier gate is in the falling state, and the end position is used to determine that the barrier gate is in the rising state, then the number of rising and falling of the barrier gate is calculated according to the number of times that the barrier gate is located at the start position and the end position, and then the position calibration is started after the number of rising and falling reaches the calibration rising and falling threshold, and the number of rising and falling of the barrier gate is recalculated after the position calibration is completed. Here, the barrier gate can be provided with a position detector at the start position and the end position respectively, so as to detect whether the barrier gate is at the start position or the end position.

[0049] In a preferred embodiment, the barrier gate needs to rise once for each rising and falling, that is, the number of times that the barrier gate stays at the end position is equal to the number of rising and falling of the barrier gate, so that the number of rising and falling of the barrier gate can be determined by calculating the number of times that the barrier gate stays at the end position, that is, when it is detected that the barrier gate stays at the end position, the number of rising and falling of the barrier gate is increased by 1.

[0050] Further, as shown in Figure 2 , the position calibration includes:

[0051] Step 11, determining the zero point of the start position and the end position.

[0052] Here, the zero point of the start position refers to the reference position of the barrier gate in the falling state, and correspondingly, the zero point of the end position refers to the reference position of the barrier gate in the rising state, and the purpose of the position calibration is to make the barrier gate return to the zero point of the start position or the end position when it falls or rises.

[0053] Step 12, determining the upper limit position and the lower limit position of the barrier gate.

[0054] Here, the upper limit position is the upper limit position of the barrier gate in the rising state, and the lower limit position is the lower limit position of the barrier gate in the falling state. It can be understood that the upper limit position and the lower limit position are used to prevent the problem of rising too much or falling too much when the barrier gate is working normally, that is, the upper limit position and the lower limit position are used to block the barrier gate.

[0055] Step 13, setting the calibration position and the calibration angle according to the zero point of the start position and the upper limit position.

[0056] Here, the upper limit position can be set as the calibration position, and the angle between the zero point of the start position and the upper limit position can be set as the calibration angle, so that the barrier gate can accurately stay at the zero point of the start position after falling according to the calibration angle after reaching the calibration position.

[0057] Of course, the calibration position and the calibration angle can also be set according to the zero point of the start position and the lower limit position, that is, the lower limit position is set as the calibration position, and the angle between the zero point of the start position and the lower limit position is set as the calibration angle, so that the barrier gate can also accurately stay at the zero point of the start position after rising according to the calibration angle after reaching the calibration position.

[0058] It can be understood that, in the above two embodiments, the zero point of the start position is taken as the final stop position of the position calibration, and based on the same principle, in other embodiments, the zero point of the end position can also be taken as the final stop position of the position calibration, which is not described here in detail.

[0059] Step 14, position calibration is performed on the barrier according to the set calibration position and calibration angle.

[0060] Here, the process of position calibration has been described in step S23, which is not described here in detail.

[0061] It should be understood that the process of position calibration can also be a lifting process of the barrier, that is, after starting the position calibration, the position calibration of the barrier can be completed through a normal lifting process of passing, so that the position calibration of the barrier can be completed in the normal working process, and the calibration process is simple and effective and does not require manual intervention.

[0062] Further, in the process of position calibration, the calibration lifting threshold can also be modified according to the position deviation status of the barrier, so that the calibration frequency of the barrier is more in line with the actual needs, so that the position calibration can also include:

[0063] Step 15, record the rotation angle of the barrier from the actual position to the calibration position.

[0064] Step 16, calculate the accumulated position deviation value of the barrier according to the rotation angle.

[0065] Step 17, adjust the calibration lifting threshold according to the position deviation value.

[0066] Here, the barrier is pre-set with a deviation threshold, and the calibration lifting threshold is adjusted according to the difference between the deviation threshold and the position deviation value during position calibration.

[0067] Specifically, the deviation threshold can be a range value, when the position deviation value is less than the minimum value of the deviation threshold, it is judged that the position deviation generated by the barrier is small, at this time the calibration lifting threshold can be increased according to the corresponding difference to delay the time of next position calibration, when the position deviation value is within the range of the deviation threshold, it is judged that the position deviation generated by the barrier meets the expectation, at this time the calibration lifting threshold remains unchanged, when the position deviation value exceeds the maximum value of the deviation threshold, it is judged that the position deviation generated by the barrier is large, at this time the calibration lifting threshold can be reduced according to the corresponding difference to advance the time of next position calibration.

[0068] For example, the initial value of the calibration landing threshold can be set to 100 times, the deviation threshold can be set to 0.5°-1.0°, after the barrier is put into use, the first landing count is completed after 500 landings, and then the first position calibration is started. When the position deviation value is detected to be 0.2°, the calibration landing threshold can be reset to 300 times, and the second landing count is started. When the landing count reaches 300 times, the second landing count is completed, and then the second position calibration is performed. When the position deviation value is detected to be 1.2°, the calibration landing threshold can be reset to 260 times, and the third landing count is started. When the landing count reaches 260 times, the third landing count is completed, and then the third position calibration is started. When the position deviation value is detected to be 0.8°, the calibration landing threshold can be kept unchanged and continuously used.

[0069] It can be understood that the position deviation condition of the barrier is detected during position calibration, whether the deviation of the barrier exceeds the expectation can be determined in time, and the calibration landing threshold is adjusted accordingly, so that the barrier can be calibrated in time or the calibration is avoided from being too frequent, so that the barrier can be in a good working state for a long time.

[0070] As can be seen, the calibration landing threshold is a dynamic value, which can better reflect the working state of the barrier. When the calibration landing threshold is stable, the larger the value is, the more stable the working state of the barrier is, and the better the quality of the barrier is. Maintenance personnel can also determine whether the barrier is abnormal by the position deviation value and the calibration landing threshold obtained during calibration.

[0071] In summary, the barrier landing position self-calibration method provided by the application can determine whether the barrier needs to be calibrated by detecting the landing count of the barrier, without measuring whether the barrier has a position deviation and without manual intervention. The barrier can be automatically calibrated during use, so that the barrier can be in a best working state for a long time.

[0072] It should be understood that, although Figures 1-2 The steps in the flowchart are displayed in sequence according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this article, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders.

It should be noted that the barrier lifting position self-calibration system 100 is consistent with the barrier lifting position self-calibration method in terms of implementation principle and implementation manner, and thus will not be described again below.
