[0030] Figure 1 A flow chart of a method for determining the action state of a boom provided in an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a method for determining the action state of an arm, and a marking point is set at a preset position on the arm. The method is applied to a processor as an example for explanation, and the method may include the following steps:

[0031] Step S101, when it is determined that the boom is displaced, it is determined whether a response signal from the boom electric control valve of the boom is received.

[0032] Step S102: if no response signal is received, obtain the first position of the identification point.

[0033] Step S103, obtaining a second position of the marking point after a preset time interval.

[0034] Step S104, determining the action state of the boom according to the first position and the second position, where the action state includes an abnormal action state and / or a normal action state.

[0035] In the embodiment of the present application, the boom may be a multi-section boom or a single-section boom, and a marking point is provided at a preset position on the boom, and the preset position may be a joint position of the boom. For example, in the case where the boom is a multi-section boom, it generally includes a main boom and a crank arm, and the preset position may include the head of the main boom, the end of the boom's boom cylinder, the head of the crank arm, and the end of the boom's boom cylinder, etc. It is understood that the above positions are only for illustration, and the selection of the preset position can be determined according to the operational requirements in the actual application scenario. It is understood that the marking point can be used to monitor the action of the boom.

[0036] In one example, the processor can obtain the position information of the identification point in real time, and judge whether the boom has been displaced according to the change of the position information of the identification point. In another example, when the boom includes multiple booms and the number of identification points is multiple, and the multiple identification points are set on different booms, the processor can judge whether the boom has been displaced according to the change of the relative position between the multiple identification points. In this way, real-time monitoring of the boom movement can be achieved.

[0037] It can be understood that the actions of all boom sections are controlled by the corresponding boom electric control valves. Only when the boom electric control valves are operating will the boom move according to the corresponding action instructions. When the boom electric control valves do not output any signals, all actions of the boom are cut off, that is, the boom should remain stationary. Therefore, when the processor detects that the boom has been displaced, in order to determine whether the displacement is due to the normal operation of the boom, that is, whether the operator is operating the boom operation, the processor can determine whether a response signal from the boom electric control valve is received while detecting the displacement of the boom. If the processor does not receive a response signal, it means that the boom displacement is not caused by the boom operation. Therefore, in order to prevent safety accidents, it is necessary to further determine whether the action state of the boom is an abnormal action state.

[0038] Specifically, the processor can obtain the first position of the identification point on the boom at the current moment, and then obtain the second position of the identification point after a preset time interval. The preset time can be set according to the actual situation. It can be understood that the first position and the second position are the position information of the identification point at different moments. In one example, the position information of the identification point can be determined by laser radar or image recognition technology. Further, the processor can determine the action state of the boom according to the first position and the second position. The action state of the boom can include an abnormal action state and a normal action state. In one example, the processor can determine the position change of the identification point according to the first position and the second position, and set a change threshold, and then determine the action state of the boom according to the position change and the change threshold. In this way, compared with the traditional method of judging whether the boom has an abnormal action by manual observation, the embodiment of the present application judges the action state of the boom based on the actual acquired boom parameters, and the possibility of error is small, and the accuracy of the judgment result is higher.

[0039] The above technical solution sets an identification point at a preset position on the boom, and judges whether a response signal of the boom electric control valve of the boom is received when the boom is determined to have displaced, and then obtains the first position of the identification point when no response signal is received, and then obtains the second position of the identification point after a preset time interval, and finally determines the action state of the boom according to the first position and the second position, and the action state includes an abnormal action state. The present application can determine the action state of the boom through the response signal of the boom electro-hydraulic control valve and the position of the boom when the boom is in action, which is conducive to accurately judging whether the boom has an abnormal action.

[0040] In the embodiment of the present application, the method further includes: upon receiving the response signal, determining that the action state of the arm is a normal action state.

[0041] Specifically, when the processor receives the response signal, it indicates that the arm displacement is caused by human operation of the arm, and at this time, the action state of the arm is determined to be a normal action state.

[0042] In an embodiment of the present application, determining whether the boom has been displaced includes: detecting position information of a marking point on the boom according to a preset period; and determining that the boom has been displaced when a change in the position information of the marking point between two adjacent periods is detected.

[0043] It can be understood that the processor can determine the displacement of the boom according to the change of the position information of the identification point. Among them, the position information of the boom can be obtained by sensors such as laser radar, or by target detection technology after being collected by an image acquisition device. Specifically, the processor can obtain the position information of the identification point on the boom according to a preset period, and determine the change of the position information of the identification point in two adjacent periods. After detecting that the position information of the identification point in two adjacent periods has changed, it is determined that the boom has displaced. In this way, the displacement of the boom can be detected in real time. Compared with traditional manual observation, it saves labor costs and improves the accuracy of the judgment results.

[0044] In an embodiment of the present application, the action state of the boom is determined according to the first position and the second position, including: determining the position deviation of the identification point according to the first position and the second position; comparing the position deviation and the deviation threshold corresponding to the identification point; when the position deviation is greater than the deviation threshold, determining that the action state of the boom is an abnormal action state.

[0045] It can be understood that the deviation threshold refers to the critical value for judging the boom movement as an abnormal movement. When the position deviation exceeds the deviation threshold, it indicates that there is a risk of an accident. The deviation threshold can be determined according to the actual application scenario and the corresponding regulatory standards. Specifically, the processor can determine the position deviation of the identification point according to the first position and the second position of the identification point, and the position deviation can be the distance between the first position and the second position. Further, the position deviation is compared with the deviation threshold corresponding to the identification point. If the position deviation is greater than the deviation threshold, it means that the displacement has exceeded the safety standard. At this time, the action state of the boom can be judged as an abnormal action state. In an example, if the boom includes only one boom section and only one identification point is set on the boom section, then when the position deviation is less than or equal to the deviation threshold, the action state of the boom is judged to be a normal action state. In this way, the abnormal action state of the boom can be effectively detected to improve the safety of the operation.

[0046] In an embodiment of the present application, there are multiple preset positions and multiple identification points, and determining the action state of the boom according to the first position and the second position includes: determining the position deviation of each identification point according to the first position and the second position of each identification point; comparing the position deviation of each identification point with the deviation threshold corresponding to each identification point; when the position deviation of each identification point is less than or equal to the corresponding deviation threshold, determining that the action state of the boom is a normal action state.

[0047] It can be understood that there can be multiple preset positions on the boom, and the number of corresponding identification points can also be multiple, and the multiple identification points are respectively set at multiple preset positions. In general, multiple identification points need to be set for a boom including multiple boom sections, and the multiple identification points can be set on different boom sections to ensure comprehensive coverage of abnormal boom movement detection. It should be noted that for a multi-section boom, since there are certain differences in the amplitudes of different boom sections during operation, the safety standards corresponding to different boom sections are also inconsistent, that is, the deviation thresholds corresponding to identification points at different positions are also inconsistent, and are all determined according to the actual position and the corresponding safety standards.

[0048] Specifically, for a boom with multiple identification points, the processor can obtain the first position and the second position of each identification point, and determine the position deviation corresponding to each identification point based on the first position and the second position of each identification point. Further, the position deviation of each identification point is compared with the corresponding deviation threshold to obtain multiple comparison results. In one example, when the position deviation of any identification point among multiple identification points is greater than the corresponding deviation threshold, it means that the action of a certain arm section of the boom exceeds the safety standard. It may be due to leakage or jamming of the cylinder, loose wire rope bolts, etc., which causes abnormal displacement of the boom, which will affect the entire boom. At this time, the action state of the boom is determined to be an abnormal action state.

[0049] In another example, when the position deviations of multiple identification points are less than or equal to the corresponding deviation thresholds, it means that the actions of each boom section meet the safety standards. The cause of the boom displacement may be due to the thermal expansion and contraction of the hydraulic oil or the elastic deformation of the wire rope, both of which are within the scope of the regulations. Reasonable settlement of the cylinder. At this time, the action state of the boom is determined to be normal. In this way, comprehensive coverage of abnormal boom action detection can be guaranteed, further improving the accuracy of the detection results.

[0050] In an embodiment of the present application, the method also includes: when the action state of the boom is an abnormal action state, determining the abnormal position of the boom based on a comparison result of the position deviation of each identification point with the corresponding deviation threshold, the abnormal position being the position of the identification point where the position deviation is greater than the deviation threshold; and outputting alarm information including the abnormal position.

[0051] Specifically, for a boom including multiple boom sections, a marking point is set at the set position of each boom section, and each marking point is associated with information of a preset position on the boom. In order to prevent accidents, when the processor determines that the action state of the boom is an abnormal action state, the abnormal position of the boom can be determined based on the comparison result of the position deviation of each marking point and the corresponding deviation threshold. The abnormal position is the position of the marking point whose position deviation is greater than the deviation threshold. Further, the processor outputs alarm information containing the abnormal position.

[0052] In one example, the alarm information can be output through a display device, which outputs an alarm and displays the abnormal location. In another example, different types of alarm signals can be set in advance for different preset locations, for example, using indicator lights of different colors to output alarm information for different locations. In this way, the operator can quickly grasp the location of the abnormality, so as to deal with it in a targeted manner, save inspection time, and improve the efficiency and safety of abnormality handling.

[0053] An embodiment of the present application also provides a processor configured to execute the method for determining the boom action state in the above-mentioned embodiment.

[0057] The second acquisition module 230 is used to acquire a second position of the marking point after a preset time interval.

[0058] The state determination module 240 is used to determine the action state of the boom according to the first position and the second position, where the action state includes an abnormal action state and / or a normal action state.

[0059] The above-mentioned device 200 for determining the action state of the boom is provided with an identification point at a preset position on the boom. When it is determined that the boom has been displaced, it is determined whether a response signal of the boom electric control valve of the boom is received. Then, when no response signal is received, the first position of the identification point is obtained, and then the second position of the identification point after a preset time interval is obtained. Finally, the action state of the boom is determined according to the first position and the second position, and the action state includes an abnormal action state. The present application can determine the action state of the boom through the response signal of the boom electro-hydraulic control valve and the position of the boom when the boom is in action, which is conducive to accurately determining the action state of the boom.
