[Specific implementation method] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention proposes a low-noise garbage compression equipment control method, system, equipment and medium, wherein the garbage compression equipment includes a push shovel, a garbage compression box and a rotating bucket or rotating frame for dumping garbage into the garbage compression box, the push shovel is integrated with the garbage compression box, and the push shovel is used to compress the garbage transported to the garbage compression box. The garbage compression equipment also includes a PLC controller for centrally controlling the operation of the push shovel and the rotating bucket or rotating frame, and a servo controller for adjusting the motor speed and reducing the motor operation noise.

[0021] Please refer to Figures 1 to 6 As shown, the embodiment of the present invention provides a low-noise garbage compression equipment control method, including steps S1-S3, wherein: S1, dumping the garbage into the garbage compression box for compression; S2, obtaining pressure data of the bulldozer during the compression process; Specifically, the pressure sensor installed at the push shovel oil cylinder can monitor the pressure data of the push shovel oil cylinder when it switches back and forth in real time, and send the real-time monitored pressure data to the PLC controller for analysis and processing; Among them, the PLC controller uses a PLC model H2U-8A91G-XP from Huichuan PLC. In specific implementation, the PLC controller can use other models of Huichuan PLC or other brands and models of PLC.

[0022] S3, based on the pressure data, determining the working mode of the shovel, and in the working mode, determining the compression state of the garbage compression box, and when the compression state is overloaded, controlling the motor of the garbage compression box to reduce the motor speed.

[0023] Specifically, the pressure data will be matched with the preset pressure threshold of the PLC controller, so that the PLC controller will output a corresponding control signal according to the matching result to control the coordination between different electromagnetic reversing valves, thereby controlling the working mode of the dozer; In addition, during the compression process of the bulldozer, the compression state of the garbage compression box (i.e., the current compression amount) is also monitored to determine whether the compression state is light load, heavy load or full load. When it is determined that the compression state of the garbage compression box reaches the heavy load state, an automatic pressure maintaining control signal is sent to the servo controller through the PLC controller. After receiving the automatic pressure maintaining control signal, the servo controller reduces the motor speed to maintain and stabilize the system pressure maintaining condition, thereby reducing the output power of the motor, thereby reducing the electromagnetic howling sound caused by the motor running, and suppressing the overflow noise of the hydraulic control system.

[0024] Wherein, the working mode includes a differential fast-forward mode and a working-forward mode; In addition, the preset pressure threshold can be written and set through the PLC controller, or written and set through the touch screen of the garbage compression device, and the touch screen is connected to the PLC controller through a communication protocol such as Modbus TCP / IP or EtherNet / IP.

[0025] Further, as a preferred implementation of this solution but not limiting, step S3 includes steps S31-S33, wherein: S31, matching the pressure data with a preset pressure threshold; S32, if it is less than or equal to the preset pressure threshold, the working mode of the push shovel is the differential fast-forward mode; S33: If the pressure is greater than the preset pressure threshold, the working mode of the shovel is the working mode.

[0026] For details, please refer to Fig.13 , the PLC controller matches the received pressure data with the preset pressure threshold, and then outputs a corresponding control signal according to the matching result, controls the coordination between different electromagnetic reversing valves, and then controls the working mode of the dozer, wherein the coordination between different electromagnetic reversing valves is shown in the action logic table; The action logic table is as follows:

[0027] Based on the above action logic table, it can be clearly analyzed that if the pressure is less than or equal to the preset pressure threshold, the PLC controller will control the electromagnetic reversing valves DT1 and DT4 to act, and the working mode of the dozer is the differential fast-forward mode; if the pressure is greater than the preset pressure threshold, the PLC controller will control the electromagnetic reversing valves DT1, DT3 and DT4 to act, and the working mode of the dozer is the working forward mode; In addition, when the forward compression action of the bulldozer is completed, the bulldozer can be retreated by controlling the electromagnetic reversing valve DT1 to operate and the other electromagnetic reversing valves to be cut off. Since the bulldozer is in a heavy-loaded state each time it retreats, that is, the pressure is basically the same each time it retreats, there is no need to monitor and judge the retreat pressure data. Only the reversal of the bulldozer oil circuit is changed by the electromagnetic reversing valve DT1, which reduces the complexity of the sensor and control logic and improves the reliability of the garbage compression equipment operation system.

[0028] The differential fast-forward mode mentioned in this embodiment is a hydraulic system that realizes a fast forward action through a differential circuit. Specifically, in this embodiment, when it is detected that the pressure data is less than or equal to the preset pressure threshold, it indicates that the current bulldozer of the garbage compression equipment is in an empty or light-loaded state, and then the electromagnetic reversing valves DT1 and DT4 are controlled to form a differential circuit to realize the fast forward of the bulldozer, thereby improving the fast action of the bulldozer in an empty or light-loaded state and improving the work efficiency. The push shovel working mode mentioned in this embodiment has a slower forward speed than the differential fast-forward mode. Specifically in this embodiment, when it is detected that the pressure data is greater than the preset pressure threshold, it indicates that the current push shovel of the garbage compression equipment is in a heavy-loaded state, and then by controlling the operation of the electromagnetic reversing valves DT1, DT3 and DT4, the push shovel is switched from the differential fast-forward mode to the working forward mode, so that the push shovel can reduce the motor running speed under the heavy-load state and operate at a forward speed slower than the differential fast-forward mode, thereby reducing the operating noise caused by the motor of the push shovel under the heavy-load state.

[0029] Further, as a preferred implementation of this solution but not limiting, step S3 also includes steps S34-S37, wherein: S34, obtaining an average differential fast-forward time of a plurality of differential fast-forwards of the dozer; S35, matching the average differential fast-forward time with a preset differential fast-forward time threshold; S36, if the average differential fast-forward time is greater than or equal to the preset differential fast-forward time threshold, it is determined that the compression state of the garbage compression box is light load; S37: If the average differential fast-forward time is less than the preset differential fast-forward time threshold, it is determined that the compression state of the garbage compression box is overloaded.

[0030] Specifically, the average differential fast-forward time of the push shovel in the garbage compression device is calculated, and the average differential fast-forward time is obtained, and then the average differential fast-forward time is matched and analyzed with the preset differential fast-forward time threshold. As the compression amount (i.e., the compression state) of the garbage compression box increases, the pressure data of the push shovel will increase, and then the push shovel will be more easily switched from the differential fast-forward mode to the working mode, making the differential fast-forward time shorter and shorter. Therefore, by matching the average differential fast-forward time of the push shovel with the preset differential fast-forward time threshold, the compression state of the garbage compression box can be more accurately determined.

[0031] Among them, the average return time of multiple differential fast-forwards of the dozer blade described in this embodiment is the average return time of the last three differential fast-forwards. In specific implementation, the average differential fast-forward time can also be calculated based on the last two or four or more differential fast-forward times.

[0032] More specifically, if the average differential fast-forward time is greater than or equal to the preset differential fast-forward time threshold, it is determined that the compression state of the garbage compression box is lightly loaded, and at this time, it can be considered that the compression amount of the garbage compression box is below 79%. It should be noted that when the compression amount of the garbage compression box is below 79% (i.e., lightly loaded), the compression amount of the garbage compression box will increase by 1% with the cycle process of the push shovel. The cycle process is a process in which the push shovel compresses the garbage forward and retreats after the compression is completed, that is, when the cycle process is executed once, the compression amount increases by 1%, and when the cycle process is executed twice, the compression amount increases by 2%, and so on, until the compression amount exceeds 79%; In addition, the preset differential fast-forward time threshold can be tested multiple times to select the most appropriate time threshold. In this embodiment, the preset differential fast-forward time threshold is set to 17 seconds. In specific implementation, the preset differential fast-forward time threshold can be adjusted accordingly according to actual conditions.

[0033] Further, as a preferred implementation mode of the present solution but not limiting, in step S37, if the average differential fast-forward time is less than the preset differential fast-forward time threshold, after determining that the compression state of the garbage compression box is overloaded, the present solution further includes step S38, wherein: S38, determining whether the compression state of the garbage compression box is full.

[0034] Further, as a preferred implementation of this solution but not limiting, step S38 includes steps S381-S383, wherein: S381, obtaining an average return time of multiple return times of the bulldozer; S382, matching the average return time with a preset minimum return time of the shovel, and determining the percentage of the garbage compression amount according to the average return time; S383: If the average return time is less than the preset minimum return time of the dozer, it is determined that the compression state is fully loaded.

[0035] Specifically, the average return time of the multiple return times of the bulldozer in this embodiment is the average return time of the last three return times. In specific implementation, the average return time can also be calculated based on the last two or four or more return times.

[0036] The average return time is used to match and analyze the preset minimum return time of the shovel to determine when the garbage compression box is full. The preset minimum return time of the push shovel in this embodiment is set to 9 seconds. In specific implementation, the preset minimum return time of the push shovel can be adjusted accordingly according to actual conditions. The matching situation of the average return time with the preset minimum return time of the push shovel and the percentage of compression amount corresponding to various situations are shown in the compression amount table of the garbage compression box; The compression amount table of the garbage compression box is as follows:

[0037] Further, as a preferred implementation of this solution but not limiting, step S1 includes steps S11-S12, wherein: S11, obtaining an operation instruction of the rotating bucket or rotating frame, wherein the operation instruction includes an ascending instruction and a descending instruction; S12, based on the operation instruction, controlling the rotating bucket or rotating frame to perform a corresponding operation.

[0038] Specifically, when it is necessary to dump the garbage into the garbage compression box for compression processing, it can be achieved by controlling the rotating bucket or rotating frame through operation instructions, and the acquisition of the operation instructions is obtained by the user through the operation of the tipping bucket up button or the tipping bucket down button on the touch screen; When the user presses the bucket rising button, the PLC controller connected to the touch screen will receive the bucket rising signal, and then the PLC controller will control the electromagnetic reversing valve DT2 to make the bucket or the rotating frame rise. At the same time, in order to ensure the flexibility of the bucket or the rotating frame rising action and reduce the running noise of the servo motor, the PLC controller will automatically adjust the speed of the servo motor through the servo controller during the rising process to eliminate the noise peak value of each stage of the action and reduce the running noise of the system; When the user presses the bucket lowering button, the PLC controller connected to the touch screen will receive the bucket lowering signal, and then the PLC controller will control the electromagnetic reversing valve DT5 to lower the bucket or the rotating frame. At the same time, in order to ensure the flexibility of the bucket or the rotating frame lowering action and reduce the operating noise of the servo motor, the PLC controller will automatically adjust the speed of the servo motor through the servo controller during the descent process to eliminate the noise wave peak value of each stage of the action and reduce the operating noise of the system.

[0039] Furthermore, as a preferred implementation mode of the present scheme but not a limitation, in the step S3, when the compression state is overloaded, the motor of the garbage compression box is controlled to reduce the motor speed, and the motor is decelerated through an automatic pressure-maintaining operation. The automatic pressure-maintaining operation is to maintain the pressure for 2-3 seconds when the shovel moves forward to the front push end point, and not maintain the pressure when it moves backward to the rear push end point.

[0040] Specifically, the automatic pressure-maintaining operation can be divided into the inching state and the long-term state of the garbage compression equipment, as shown in the following automatic pressure-maintaining strategy table. The automatic pressure maintaining strategy table is:
