[0043] The embodiments of the application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the application, and cannot be understood as limiting the application.
[0044] Figure 1 The hydraulic support support state control method provided by the embodiments of the application comprises:
[0045] Step S110: when the hydraulic support to be controlled is running to the working state, the hydraulic support pose state information is collected.
[0046] The present application measures and collects the inclination changes of the guard, connecting rod and base of the hydraulic support to be controlled in real time by arranging multi-three-axis inclination sensors on the guard, connecting rod and base of the hydraulic support to be controlled, and obtains the pose state information of the guard, connecting rod and base of the hydraulic support to be controlled.
[0047] The present application adopts three-axis inclination sensors and inner ring high-precision inclination measuring units, converts the inclination changes into inclination by measuring the static gravity acceleration, so as to measure the inclination and pitch angle of the sensor output relative to the horizontal plane. The three-axis inclination sensor is very suitable for application in the field of hydraulic support monitoring with high precision, has the characteristics of strong anti-electromagnetic interference ability, and is suitable for long-term work in harsh industrial environments. The characteristics are as follows:
[0048] (1) high measurement precision, with high-performance MCU built-in algorithm, high-frequency characteristics of data are improved through high oversampling rate, and higher precision data processing is performed through Kalman filtering algorithm after unreasonable sporadic error data is removed through data filtering algorithm.
[0049] (2) high resolution, with built-in 24-bit ADC sampling, the resolution is as high as 0.0001°, and the extremely small angle change can be sensed.
[0050] (3) digital communication and industrial quality, output standard RS485 digital signal; with IP68 protection level, can work in the environment of-40℃ to +85℃, and can be used in various harsh environments.
[0051] In the embodiment, three-axis inclination sensors are respectively installed on the guard, front and rear connecting rods and base of the hydraulic support, the installation positions are as shown in Figure 2 The inclination changes of the guard, front and rear connecting rods and base of the hydraulic support are measured in real time by the inclination sensors, and the processing of the support pose monitoring system is performed to achieve the purpose of real-time monitoring of the guard and the support pose of the hydraulic support.
[0052] In the process of the guard stretching and retracting, when the adhesion of the guard and the coal wall appears to be separated, whether the guard stretching and retracting state is in a reasonable range is monitored, if the condition is met, the guard continues to stretch and retract, if the condition is not met, the attitude of the hydraulic support is adjusted to adapt to the adhesion of the guard and the coal wall being always in the ideal range.
[0053] When judging the pose state information of the guard of the hydraulic support, the steps include:
[0054] Before the hydraulic support to be controlled starts to act, the attitude angle of the three-axis inclination sensor arranged on the guard is collected, and is set as the initial attitude angle.
[0055] In the hydraulic support action process to be controlled, the posture angle of the three-axis inclination sensor arranged on the support is collected in real time, and the final posture angle after stopping the action is determined;
[0056] Based on the initial posture angle and the final posture angle, the first stretching state of the support is determined;
[0057] Based on the initial posture angle and the final posture angle, the second stretching state of the support is determined according to the angle change;
[0058] When the first stretching state and the second stretching state are consistent, the final pose state information of the support is determined.
[0059] Specifically, the state of the support inclination angle perpendicular to the downward direction is taken as a reference to establish a reference coordinate system. When the support moves, the three-axis inclination value of the support will change accordingly, and the stretching state of the support can be monitored through the change of the inclination angle.
[0060] The current posture angle of the support inclination angle is read, and the posture angle is set as the reference angle (θ x0 , θ y0 , θ z0 ), by monitoring the posture angle of the support in real time, according to the change of the three-axis inclination value, the first stretching state of the support can be determined.
[0061]
[0062] Table 1 First support state monitoring
[0063] The target difference value of the support inclination angle change is set, and the z-axis angle change value△Θ zt When the cumulative target difference value is reached, it is judged that the support stretching is completed, and when the support inclination angle data does not change within a certain time, it is further judged that the stretching is completed, and the support stretching state 2 is confirmed. As shown in Table 2.
[0064]
[0065] Table 2 Second support state monitoring
[0066] When the first support state and the second support state are consistent, the final pose state of the support can be determined.
[0067] Similarly, the support pose monitoring control system reads the posture angle of the inclination sensor of the base, and sets the posture angle as the reference angle (θ x0 , θ y0 , θ z0), by real-time monitoring of the base attitude angle changes, such as Table 3, according to the change of three-axis tilt angle value, the first inclination state of the base can be judged.
[0068]
[0069] Table 3 Hydraulic support base first inclination state monitoring
[0070] By setting the inclination change difference respectively, when the y-axis angle change amount accumulates to the target difference within the action time of the two, the second inclination state of the hydraulic support base is judged, as shown in Table 4, and when the base inclination data does not change within a certain time, the overall state of the hydraulic support base is further judged.
[0071]
[0072] Table 4 Hydraulic support base second inclination state monitoring
[0073] When the first inclination state of the base and the second inclination state of the base are consistent, the final pose state of the base can be determined.
[0074] Step S120: constructing a hydraulic support model corresponding to the hydraulic support to be controlled, and inputting the collected hydraulic support pose state information into the hydraulic support model.
[0075] Specifically, a hydraulic support model corresponding to the hydraulic support to be controlled in the same proportion is constructed in the three-dimensional model software;
[0076] Extracting the final attitude angle of the three-axis tilt angle sensor set on the guard, connecting rod and base in the pose state information of the hydraulic support to be controlled;
[0077] According to the final attitude angle of the three-axis tilt angle sensor set on the guard, connecting rod and base, the pose state of the guard, connecting rod and base of the hydraulic support model is adjusted.
[0078] Step S130: judging whether the hydraulic support model running according to the actual hydraulic support pose state data is in a stable state in the working environment model corresponding to the working environment of the hydraulic support to be controlled.
[0079] Specifically, while constructing the hydraulic support model corresponding to the hydraulic support to be controlled in the same proportion, a working environment model corresponding to the actual working environment of the hydraulic support to be controlled in the same proportion is constructed;
[0080] After adjusting the hydraulic support model according to the pose state information of the hydraulic support to be controlled, the fit of the guard of the hydraulic support model and the working face coal wall of the working environment model, and the fit of the base of the hydraulic support model and the position of the roadway ground are observed in the three-dimensional model.
[0081] If the hydraulic support model's guard and the working environment model's working face coal wall are in contact, and the hydraulic support model's base and the roadway ground at the location are in contact, the hydraulic support model is in a stable state in the working environment model.
[0082] Step S140: If in a non-equilibrium state, fine-tune the pose state information of the hydraulic support model to make the hydraulic support model in an equilibrium state.
[0083] Specifically, if the hydraulic support model's guard and the working environment model's working face coal wall are not in contact, and / or the hydraulic support model's base and the roadway ground at the location are not in contact, the pose of the hydraulic support model's guard is adjusted to make the hydraulic support model's guard and the working environment model's working face coal wall in contact.
[0084] When the hydraulic support model's guard and the working environment model's working face coal wall are in contact, the poses of the hydraulic support model's connecting rod and base are adjusted to make the hydraulic support model's guard and the working environment model's working face coal wall in contact.
[0085] Step S150: According to the hydraulic support model's pose state information after fine-tuning and being in an equilibrium state, adjust the pose of the hydraulic support to be controlled to make the hydraulic support to be controlled in an equilibrium state.
[0086] To realize the real-time contact requirement of the guard and the coal wall, the action posture of the guard in the hydraulic support is monitored and accurately controlled all the time, and the overall pose state of the hydraulic support is effectively controlled, and the support quality is real-time evaluated. The present application provides a control scheme of the hydraulic support support state, and a control scheme architecture diagram is shown as Figure 3 The specific technical scheme is as follows:
[0087] The support pose monitoring control system controls the extension and retraction state of the guard first through the pose target output module based on the monitoring process, and controls the guard to be in contact with the coal wall. In the process of the guard extension and retraction state, when the contact between the guard and the coal wall appears to be separated, the support pose monitoring control system will monitor whether the guard extension and retraction state is within a reasonable range. If the condition is met, the guard continues to extend and retract state is adjusted; if the condition is not met, the pose of the hydraulic support is adjusted to adapt to the contact between the guard and the coal wall to be always within the ideal range. The control method is divided into three parts.
[0088] a. Pose monitoring stage: based on the pose monitoring of the guard and the hydraulic support, information is obtained. Specifically, the front and back change difference Δtz of the guard inclination angle, the connecting rod inclination angle and the base inclination angle is obtained, which is compared with the target difference value respectively, and the analysis result is transmitted to the support pose monitoring control system, and then the poses of the guard and the hydraulic support are obtained respectively, and only the real-time pose information of the guard is fed back to the support pose monitoring control system.
[0089] b. Data processing stage: after the model fuses the data, the adjusted pose target information is output, and the priority of the target information from high to low is the support pose target information, the connecting rod pose target information and the base pose target information in turn, and the priority is to first adjust the real-time fitting of the support and the coal wall, and then sequentially fine-tune the pose of the connecting rod and the base of the hydraulic support.
[0090] c. Pose control stage: the electro-hydraulic controller of the hydraulic support receives the target pose and issues the adjusted pose to the support, the connecting rod and the base. After the support completes the real-time fitting with the coal wall, the adjusted pose is preferentially fed back to the support pose monitoring control system for data processing, and then the instructions are sequentially issued to the connecting rod and the base for pose fine-tuning.
[0091] As shown in Figure 4 , the present application proposes a control device 300 for the support state of a hydraulic support, comprising:
[0092] The acquisition module 310 is used to acquire the hydraulic support pose state information when the hydraulic support to be controlled is running to the working state;
