Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Fig. 1 is a schematic flow chart of a method for automatically determining workload of an excavator in a mining process provided in the present application, as shown in fig. 1, the method includes:
Specifically, fig. 2 is a schematic diagram of an interaction scenario of each device in a mining process provided by the present application, and as shown in fig. 2, an excavator workload determination system in an embodiment of the present application includes a remote workload statistics platform, an ore card terminal installed on each ore card (i.e. a mining truck), and an excavator terminal installed on each excavator. The automatic determination device of the workload of the excavator in the mining process is used for automatically determining the workload of the excavator based on the automatic determination method of the workload of the excavator in the mining process.
It can be understood that the mine site comprises a plurality of mine cards and the excavator to cooperatively work to realize efficient mining, and the mine cards and the excavator in the mine site can be orderly scheduled in the mining process so as to ensure continuous work of each mine card and the excavator, and avoid the situation that the mine cards wait for loading and the excavator wait for unloading. Meanwhile, a plurality of different types of mining cards and a plurality of different types of excavators can exist in the same mine so as to meet mining requirements.
In the mining process, a certain excavator moves to a designated place to discharge after the ore is dug, so that minerals are transferred to an ore card parked at the designated place, the ore card starts to transport the minerals to a destination after being fully loaded, the ore card arrives at the destination and returns to the designated place to continue to be discharged by the excavator after the ore card finishes discharging, and accordingly the ore card reciprocates, and ordered mining of a mining place can be achieved. The identity of the ore card is stored in the ore card terminal, the identity of the excavator is stored in the excavator terminal, when the excavator is close to the ore card for unloading, the ore card terminal can communicate with the excavator terminal to acquire the identity of the excavator, and meanwhile, a weight sensor in the ore card can record the weight change of the ore card during unloading of the excavator so as to accurately determine the current unloading amount of the excavator when unloading. Considering that the carrying capacity of different types of excavators is different, and the corresponding unloading time is also different, therefore, the mine card terminal in the embodiment of the application can determine the type of the excavator based on the identity of the excavator after acquiring the identity of the excavator, determine the unloading time length of the excavator based on the type of the excavator, and take the weight change of the mine card recorded in the unloading time length as the unloading amount of the excavator. It can be understood that the unloading time length of the excavator can be increased by a section of emergency time length to avoid the extension of the unloading process of the excavator caused by emergency, and based on the extension, the unloading amount acquisition accuracy of the excavator can be ensured. After the unloading is finished based on the unloading time length, the mine card terminal generates an excavator unloading message based on the obtained excavator identity identification and the corresponding unloading amount.
The mine card terminal is also recorded with a preset full-load weight reference value, and the full-load weight reference value is determined based on the type of the mine card corresponding to the mine card terminal. And in the loading process of the ore card, the ore card terminal can determine whether the ore card is fully loaded in real time based on the measured value of the load sensor, and inform the excavator to stop unloading under the condition that the ore card is fully loaded, and generate an excavator unloading information subsequence corresponding to the current transportation cycle based on the excavator unloading information recorded during loading. The pieces of excavator unloading information in the excavator unloading information subsequence are arranged in time sequence. It can be understood that the generation time of the unloading information of each excavator is also recorded in the unloading information subsequence of the excavator, so that the workload statistics of the target excavator can be performed later. The transportation period refers to a period between two unloading processes of the ore card, namely, a period corresponding to a process of returning to a designated place for loading after the previous unloading process is completed at a destination and driving to the destination after full loading to complete unloading again. Based on the foregoing, it can be seen that the sub-sequence of excavator discharge information corresponding to the current transportation cycle is generated substantially based on the excavator discharge information recorded during loading. It is noted that in the case where the mine truck is fully loaded but the excavator is not completed in the next unloading process, the mine truck terminal still generates an excavator unloading message based on the recorded unloading amount of the excavator, and other empty mine trucks are scheduled for the excavator with the incomplete unloading process to continue unloading. After the mining card terminal generates the excavator unloading information subsequence corresponding to the current transportation period, the mining card terminal sends the excavator unloading information subsequence to a remote workload statistics platform for the automatic determination device of the excavator workload in the mining process to carry out excavator workload statistics. It can be understood that the mine card terminal uploads the self identity mark so as to carry out identity recognition while uploading the unloading information subsequence of the excavator. Based on this, the automatic determination device of the excavator workload during mining may receive the excavator discharge information subsequences corresponding to different transportation cycles uploaded by the mine card terminals associated with the current mine.
Specifically, after the excavator unloading information subsequences uploaded by each mine card terminal are obtained, the automatic determining device of the workload of the excavator in the mining process can splice a plurality of excavator unloading information subsequences uploaded by the same mine card based on the sequence of uploading time so as to obtain the corresponding excavator unloading information sequence in the current mine card mining process. Based on the foregoing, the generation time of the unloading information of each excavator is recorded in the unloading information subsequence of each excavator, so that the unloading information sequence of each excavator corresponding to each mine card in any statistical period can be determined based on the corresponding unloading information sequence of each excavator in the mining process of each mine card. It can be appreciated that the statistical period can be preset or determined based on the statistical condition actively input by the user, and based on this, the flexibility of the workload statistics of the excavator can be ensured.
Specifically, based on the foregoing, each piece of excavator unloading information includes an excavator identity identifier, based on which, after the excavator unloading information sequence corresponding to each mine card in the preset statistical period is obtained, an excavator unloading information set corresponding to the target excavator in the preset statistical period is determined based on the excavator unloading information sequence corresponding to each mine card in the preset statistical period, and the workload in the preset statistical period of the target excavator is determined based on the number of the excavator unloading information in the excavator unloading information set and the unloading amount corresponding to each piece of excavator unloading information. It can be appreciated that the existing statistical manner of workload of the excavator is mostly based on the number of times of unloading of the excavator (corresponding to the number of unloading information of the excavator in the unloading information set of the excavator) as a measurement standard, but the manner is easy to generate workload cheating behavior, namely, the operator of the excavator can intentionally reduce the single-time excavation amount to increase the unloading number when performing the mining operation. Based on the above, the embodiment of the application can perform comprehensive evaluation on the workload of the target excavator in the preset statistical period based on the quantity of the unloading information of the excavator in the unloading information set of the excavator and the unloading quantity corresponding to the unloading information of each excavator, so as to avoid enterprise asset loss caused by serious discrepancy between the statistical information of the workload of the excavator and actual conditions to the maximum extent.
According to the method provided by the embodiment of the application, the excavator unloading information subsequences corresponding to different transportation periods uploaded by the mine card terminal associated with the current mine are received; each excavator unloading information subsequence comprises a plurality of pieces of excavator unloading information which are arranged in time sequence and correspond to the same transportation period of the same mine truck, and the excavator unloading information comprises excavator identification marks and corresponding unloading amounts; the excavator body identification is read from the excavator terminal by the ore card terminal during unloading of the excavator, and the unloading amount is determined by the ore card terminal based on the weight change of the ore card during unloading of the excavator; based on the excavator unloading information subsequence uploaded by each mine card terminal, acquiring an excavator unloading information sequence corresponding to each mine card in a preset statistical period; the method comprises the steps of determining an excavator unloading information set corresponding to a target excavator in a preset counting period based on an excavator unloading information sequence corresponding to each mine card in the preset counting period, and determining the workload in the preset counting period of the target excavator based on the quantity of the excavator unloading information in the excavator unloading information set and the unloading quantity corresponding to each excavator unloading information, so that automatic accurate counting of the workload of the excavator in the mining process can be realized, labor cost is saved, and enterprise asset loss caused by discrepancy between the workload counting information of the excavator and actual conditions is avoided.
Based on the foregoing embodiment, fig. 3 is a schematic diagram of a determining flow of an excavator unloading information set provided in the present application, as shown in fig. 3, where determining, based on an excavator unloading information sequence corresponding to each mine card in a preset statistical period, an excavator unloading information set corresponding to a target excavator in the preset statistical period specifically includes:
Specifically, according to the foregoing embodiment, in the case that the mine truck is fully loaded but the excavator is not completed in the next unloading process, the mine truck terminal still generates an excavator unloading message based on the recorded unloading amount of the excavator, and meanwhile, other empty mine trucks are scheduled for the excavator with the incomplete unloading process to continue unloading. It follows that in this case, a single excavated mineral from the same excavator will be split into two different mine cards, which will result in the two mine cards uploading excavator discharge information sub-sequences each including an incomplete piece of excavator discharge information. It is understood that the incomplete unloading information of the excavator does not record the unloading amount corresponding to one complete unloading process of the excavator, which leads to statistical errors in subsequent workload statistics based on the unloading times. Accordingly, embodiments of the present application aim to combine corresponding two pieces of incomplete shovel discharge information to ensure that each shovel discharge information corresponds to a complete discharge process. The specific process is as follows:
Firstly, determining an initial excavator unloading information set corresponding to a target excavator in a preset statistical period based on an excavator unloading information sequence corresponding to each mine card in the preset statistical period, namely determining excavator unloading information corresponding to the target excavator in the excavator unloading information sequence corresponding to each mine card in the preset statistical period, and combining the excavator unloading information to obtain the initial excavator unloading information set.
After the initial excavator unloading information set is acquired, the excavator unloading information association pair in the initial excavator unloading information set can be determined based on the position of each excavator unloading information in the corresponding excavator unloading information subsequence in the initial excavator unloading information set and the generation time of each excavator unloading information. Based on the foregoing, it can be known that the situation that the minerals excavated by the same excavator are split into two different ore cards at a single time only occurs in the last loading of the first ore card and the first loading of the second ore card, so that the incomplete excavator unloading information is only located at the head and tail positions in the corresponding excavator unloading information subsequence, the generation time of the two incomplete excavator unloading information is continuous (that is, the generation time interval is smaller than the preset time length), and based on the association relationship, the excavator unloading information association pair in the initial excavator unloading information set can be rapidly determined. Fig. 4 is a schematic flow chart of determining an excavator unloading information association pair provided in the present application, as shown in fig. 4, where determining, based on a position of each excavator unloading information in the initial excavator unloading information set in a corresponding excavator unloading information subsequence and a time of generating each excavator unloading information, the excavator unloading information association pair in the initial excavator unloading information set specifically includes:
It can be appreciated that the preset time period may be set based on actual situations, which is not specifically limited in the embodiments of the present application. Based on the steps 301-302, quick and accurate determination of the associated pair of unloading information of the excavator can be realized.
After the excavator unloading information association pair is determined, two pieces of excavator unloading information in the excavator unloading information association pair can be combined into one piece, so that an excavator unloading information set corresponding to the target excavator in a preset statistical period is obtained.
Combining the two pieces of excavator unloading information in the excavator unloading information association pair into one piece, specifically comprising:
deleting repeated excavator identity identifiers in the first excavator unloading information and the second excavator unloading information in the excavator unloading information association pair, and simultaneously taking the sum of the unloading amounts in the first excavator unloading information and the second excavator unloading information as the combined unloading amount, so that each piece of excavator unloading information in the excavator unloading information set can be ensured to correspond to a complete unloading process, and further the accuracy of the follow-up excavator workload statistics is ensured.
According to the method provided by the embodiment of the application, the excavator unloading information set corresponding to the target excavator in the preset statistical period is determined based on the excavator unloading information sequence corresponding to each mine card in the preset statistical period, and the method specifically comprises the following steps: determining an initial excavator unloading information set corresponding to a target excavator in a preset statistical period based on an excavator unloading information sequence corresponding to each mine card in the preset statistical period; determining an excavator unloading information association pair in the initial excavator unloading information set based on the position of each excavator unloading information in the corresponding excavator unloading information subsequence and the generation time of each excavator unloading information in the initial excavator unloading information set, and merging two pieces of excavator unloading information in the excavator unloading information association pair into one piece so as to obtain an excavator unloading information set corresponding to the target excavator in a preset statistical period, wherein the accuracy of each excavator unloading information in the excavator unloading information set corresponding to the target excavator in the preset statistical period can be ensured, and further the accuracy of the follow-up excavator workload statistics is ensured.
Based on any of the foregoing embodiments, fig. 5 is a schematic diagram of a workload determination flow in a preset statistical period of a target excavator, where, as shown in fig. 5, the workload determination in the preset statistical period of the target excavator is determined based on the number of unloading information of the excavator in the unloading information set of the excavator and the unloading amount corresponding to each unloading information of the excavator, and specifically includes:
Specifically, as can be seen from the foregoing embodiments, the existing statistical manner of workload of the excavator is mostly based on the unloading times of the excavator as a measurement standard, but this manner is easy to generate workload fraud, i.e. the operator of the excavator can intentionally reduce the single excavation amount to increase the unloading times when performing the mining operation. In order to avoid the statistical error of the workload of the excavator caused by fraud, the embodiment of the application determines the fluctuation interval of the unloading amount of the target excavator based on the mineral type of the current mine and the type of the target excavator, and it can be understood that if the unloading amount corresponding to the unloading information of the excavator in the unloading information set of the excavator is not in the fluctuation interval of the unloading amount, the possible workload fraud is described, so that the embodiment of the application determines the statistical type of the workload of the target excavator based on the matching result of the unloading amount corresponding to the unloading information of each excavator in the unloading information set of the excavator and the fluctuation interval of the unloading amount of the target excavator so as to avoid the statistical error of the workload caused by fraud. After the workload statistical type of the target excavator is determined, the workload in the preset statistical period of the target excavator can be determined based on the workload statistical type of the target excavator by combining the quantity of the unloading information of the excavator in the unloading information set of the excavator and the unloading quantity corresponding to the unloading information of each excavator.

Specifically, the ratio of the target discharge amount is the ratio of the number of the target discharge amounts to the total discharge amount in the excavator discharge information set. Considering that the excavator cannot realize full loading of the bucket at a certain stage possibly caused by mining difficulty and the like in the actual mining process, and is not intentionally tampered, in order to further ensure the accuracy of workload statistics, in the embodiment of the application, the workload statistics type of the target excavator is a first type only when the ratio of the target unloading amount is greater than a preset threshold value, otherwise, the workload statistics type of the target excavator is a second type;
Correspondingly, the determining the workload in the preset statistical period of the target excavator based on the workload statistical type of the target excavator and combining the quantity of the unloading information of the excavator in the unloading information set of the excavator and the corresponding unloading quantity of the unloading information of each excavator specifically comprises the following steps:
if the workload statistical type of the target excavator adopts a first type, taking the sum of the unloading amounts corresponding to the unloading information of each excavator as the workload in the preset statistical period of the target excavator, namely, taking the total weight of unloading of the excavator as a measurement standard of the workload when the proportion of the target unloading amount is larger than a preset threshold value. And if the workload statistics type of the target excavator adopts a second type, taking the quantity of the unloading information of the excavator in the unloading information set of the excavator as the workload in the preset statistics period of the target excavator, namely, taking the unloading times of the excavator as a measurement standard of the workload when the proportion of the target unloading quantity is smaller than a preset threshold value. Based on the method, the working capacity statistical error of the excavator caused by fraud can be avoided to the maximum extent on the basis of considering the statistical efficiency.
