Figure 3As shown by the dotted line in the middle; the real-time mass of each filling cavity inside the counterweight is detected in real time by the weighing sensor, so as to effectively determine whether the overall counterweight is evenly weighted after the filling of the ingredients is completed;

[0074] A data collection module, wherein the data collection module is connected to the weighing sensor signal inside the counterweight to receive the real-time detection data of each weighing sensor in real time; the data collection module receives the real-time detection data from each weighing sensor in real time, and transmits the received real-time detection data of each weighing sensor to the data processing module;

[0075] A data processing module, wherein the data processing module pre-processes the real-time detection data received from each weighing sensor; the data processing module implements pre-processing such as noise reduction and de-duplication of the real-time detection data, thereby further improving the accuracy and credibility of the real-time detection data;

[0076] A data analysis module, the data analysis module comprising a preset target unit, a data comparison unit, an over-limit determination unit and a counterweight distribution unit;

[0077] The preset target unit stores target parameters of each filling cavity and target parameters of the counterweight as a whole; wherein the target parameters of each filling cavity include preset center of mass position parameters of each filling cavity; the target parameters of the counterweight as a whole include preset center of mass position parameters of the counterweight as a whole; the preset target unit determines the preset center of mass position parameters of each filling cavity according to the counterweight requirement of the counterweight and the filling cavity parameters inside the counterweight, and then determines the preset center of mass position parameters of the counterweight as a whole according to the preset center of mass positions of each filling cavity;

[0078] In this embodiment,

[0079] The preset centroid position parameters of each filling cavity are calculated according to the following formula:

[0080]

[0081]

[0082]

[0083] in,

[0084] , , are respectively the X-, Y- and Z-direction coordinates of the preset centroid position of each filling cavity;

[0085] For the i The preset mass at each load cell location;

[0086] , Respectively i The X, Y and Z coordinates of the location of each load cell;

[0087] The preset center of mass position parameters of the counterweight as a whole are calculated according to the following formula:

[0088]

[0089]

[0090]

[0091] in,

[0092] , , are respectively the X-, Y- and Z-direction coordinates of the preset center of mass position of the counterweight as a whole;

[0093] For the j Preset quality of each filling cavity;

[0094] , Respectively j Preset X, Y and Z coordinates of the location of each filling cavity;

[0095] The data calculation unit calculates and obtains actual parameters of each filling cavity and actual parameters of the entire counterweight according to the pre-processed real-time detection data;

[0096] The data comparison unit compares the preprocessed real-time detection data with the target parameters of each filling cavity and the overall target parameters of the counterweight respectively;

[0097] When the data comparison unit compares the pre-processed real-time detection data with the target parameters of each filling cavity:

[0098] The data calculation unit first determines the actual center of mass position parameters of each current filling cavity according to the pre-processed real-time detection data;

[0099] Calculated according to the following formula:

[0100]

[0101]

[0102]

[0103] in,

[0104] , , are the X-, Y- and Z-direction coordinates of the actual centroid position of each filling cavity, respectively;

[0105] For the i Real-time detection data of weighing sensors;

[0106] , Respectively i The X, Y and Z coordinates of the location of each load cell;

[0107] Then, the actual center of mass position parameters of each filling cavity are compared with the preset center of mass position parameters. When the difference between the two exceeds the preset range of the filling cavity, it is recorded in the filling cavity over-limit record;

[0108] When the data comparison unit compares the pre-processed real-time detection data with the overall target parameters of the counterweight:

[0109] The data calculation unit first determines the actual center of mass position parameters of the current counterweight as a whole according to the determined actual center of mass position parameters of each current filling cavity;

[0110] Calculated according to the following formula:

[0111]

[0112]

[0113]

[0114] in,

[0115] , , are the X-, Y- and Z-axis coordinates of the actual center of mass of the counterweight as a whole;

[0116] For the j The actual mass of the filled cavity;

[0117] , Respectively j The actual X, Y and Z coordinates of the location of each filling cavity;

[0118] The actual center of mass position parameters of the counterweight as a whole are then compared with the preset center of mass position parameters. When the difference between the two exceeds the preset range of the counterweight, it is recorded in the counterweight overlimit record.

[0119] The overrun determination unit determines the overrun parameters of each filling cavity according to the corresponding comparison results;

[0120] The overrun determination unit simultaneously obtains corresponding overrun records in the counterweight overrun record and the filling cavity overrun record to determine:

[0121] 1) The number and position of the over-limit filling cavity; it affects the filling type, filling quantity and filling position of the subsequent balancing weight material;

[0122] 2) The over-limit direction of the over-limit filling cavity; it affects the determination of the subsequent weight distribution method;

[0123] When the overrun determination unit determines the number and position of the overrun filling chambers, the number and position of the overrun filling chambers are determined according to the horizontal position of the overrun record of the counterweight: Figure 4 ,by Figure 3 Take the filling cavity in as an example:

[0124] When the horizontal position where the counterweight overrun record is located in the exclusive area of ​​a single filling cavity ( Figure 4 When the first area 11 in the exclusive area is determined, the number of the current over-limit filling cavity is determined to be 1, and the over-limit filling cavity is the first filling cavity 1 corresponding to the exclusive area;

[0125] When the horizontal position where the counterweight overrun record is located is located in the adjacent area of ​​a single filling cavity ( Figure 4 When the number of currently over-limit filling cavities is determined to be at least 2, the over-limit filling cavities are the filling cavities corresponding to the adjacent areas (the filling cavities corresponding to the adjacent area 12 are the first filling cavity 1 and the second filling cavity 2, and the filling cavities corresponding to the adjacent area 13 are the first filling cavity 1 and the third filling cavity 3);

[0126] By dividing the exclusive area and adjacent areas, the number and location of the over-limit filling cavity can be effectively determined, thus providing a reliable and accurate basis for the subsequent determination of the filling type, filling quantity and filling location of the ballast material;

[0127] In the data analysis module, when the overrun determination unit determines the overrun direction of the overrun filling cavity, the overrun direction of the overrun filling cavity is determined according to the vertical position of the overrun record of the filling cavity:

[0128] When the vertical position of the filling cavity overrun record is above the vertical position of the preset center of mass of the filling cavity, it is determined that the overrun direction of the current overrun filling cavity is the underweight direction; this indicates that the filling cavity is underweighted at this time, and therefore it is necessary to continue to add counterweight inside the overrun filling cavity;

[0129] When the vertical position of the filling cavity overrun record is below the vertical position of the preset center of mass of the filling cavity, it is determined that the overrun direction of the current overrun filling cavity is the overweight direction; this indicates that the filling cavity is overweighted at this time, and therefore the counterweight needs to be appropriately reduced inside the overrun filling cavity;

[0130] By determining the over-limit direction of the over-limit filling cavity, an effective reference and assistance can be provided for determining the subsequent counterweight distribution method.

[0131] The counterweight distribution unit distributes the corresponding counterweight to each filling cavity inside the counterweight according to the determined overrun parameters of each filling cavity; the counterweight distribution unit determines the counterweight distribution mode according to the overrun direction of the overrun filling cavity, and determines the filling type, filling quantity and filling position of the counterweight material according to the number and position of the overrun filling cavity, thereby further improving the accuracy and effectiveness of counterweight adjustment;

[0132] A counterweight test module, the counterweight test module is connected to the counterweight test bench to test and inspect the counterweight after the counterweight distribution through the counterweight test bench;

[0133] A counterweight using module, wherein the counterweight using module is connected to a counterweight real vehicle so as to conduct a real vehicle inspection of the counterweight part after the counterweight test through the counterweight real vehicle;

[0134] A counterweight optimization module, one end of which is respectively connected to the counterweight test module and the counterweight use module signal, and the other end is connected to the data analysis module, so as to optimize the data analysis module accordingly according to the test results of the test and the actual vehicle test; the content of the data analysis module optimization includes but is not limited to: the calculation process and parameters of the target parameters of each filling cavity and the overall target parameters of the counterweight, as well as the actual parameters of each filling cavity and the actual parameters of the overall counterweight; the process and parameters for determining the over-limit parameters of each filling cavity; the corresponding counterweight distribution process and parameters for each filling cavity inside the counterweight, etc. By setting up the counterweight optimization module, the data analysis module is correspondingly optimized according to the test results of the test and the actual vehicle test, so that the data analysis module is simultaneously optimized in the short term and the long term in combination with the short-term test and the long-term actual vehicle test, so as to further improve the effectiveness and accuracy of the data analysis module.

[0135] Preferably, when the counterweight optimization module optimizes the data analysis module accordingly according to the inspection results of the experimental inspection and the actual vehicle inspection, the reference priority of the inspection results of the actual vehicle inspection is higher than the reference priority of the inspection results of the experimental inspection. On the one hand, this is because the experimental inspection environment cannot effectively simulate the various special operating conditions of the actual vehicle, so its reference value is not as good as the actual vehicle inspection environment; in addition, in actual use, the counterweight can also be used in different heavy machinery and load-carrying vehicles, so at this time the use environment of the counterweight will be different from the experimental inspection environment.

[0136] [Second embodiment]

[0137] The second embodiment of the present invention further provides a method for controlling a counterweight distribution system, comprising the following steps:

[0138] S1: The weighing sensor detects the weight of each filling cavity inside the counterweight in real time;

[0139] S2: The data collection module receives the real-time detection data of each weighing sensor in real time;

[0140] S3: The data processing module pre-processes the received real-time detection data of each weighing sensor;

[0141] S4: The data analysis module compares the pre-processed real-time detection data with the target parameters of each filling cavity and the overall target parameters of the counterweight, determines the over-limit parameters of each filling cavity according to the corresponding comparison results, and then distributes the corresponding counterweight to each filling cavity inside the counterweight according to the determined over-limit parameters of each filling cavity;

[0142] S5: The counterweight test module conducts a test on the counterweight parts after counterweight distribution through the counterweight test bench;

[0143] S6: The counterweight use module conducts a real vehicle inspection of the counterweight parts after the counterweight test through a real vehicle;

[0144] S7: The weight optimization module optimizes the data analysis module accordingly according to the test results of the experimental inspection and the actual vehicle inspection.
