Description

Technical Field

[0001] This invention relates to the field of construction machinery technology, and in particular to a method, monitoring device, and concrete mixer truck for monitoring the transportation status of a concrete mixer truck. Background Technology

[0002] During the transportation of premixed materials, concrete mixer trucks are prone to feeding additional materials, thus requiring monitoring of the transportation process. Monitoring this process necessitates obtaining transportation information such as the truck's starting point, destination, and real-time location throughout the transportation process. The starting point is the mixing plant, and the destination is the construction site.

[0003] Existing methods for obtaining transportation information through manual entry or integration with enterprise resource planning systems suffer from drawbacks such as cumbersome operation and low efficiency. As a result, the methods for monitoring the concrete mixer truck transportation process are also cumbersome and inefficient. Summary of the Invention

[0004] This invention provides a method, device, and truck for monitoring the transportation status of a concrete mixer truck, which solves the problems of cumbersome and inefficient acquisition of transportation information when monitoring the transportation status of a concrete mixer truck in the prior art, and realizes simple and efficient monitoring of the transportation status of a concrete mixer truck.

[0005] This invention provides a method for monitoring the transportation status of a concrete mixer truck, comprising:

[0006] When basic information of a mixer truck for at least one complete transportation route is received, the location of the mixing plant and the construction site are determined based on the basic information of the mixer truck; the complete transportation route includes the entire transportation route of a mixer truck from loading to unloading; the basic information of the mixer truck includes the real-time location of the mixer truck and the forward and reverse rotation information of the mixing drum.

[0007] The transportation status of the concrete mixer truck is monitored based on the location of the mixing plant, the location of the construction site, and the real-time basic information of the mixer truck.

[0008] According to the present invention, a method for monitoring the transportation status of a concrete mixer truck, based on the basic information of the mixer truck, determines the location of the mixing plant and the construction site, specifically including:

[0009] When only the basic information of the mixer truck for the first complete transportation route is received, the position of the mixer truck that simultaneously meets the conditions of earliest reception time, forward rotation of the mixing drum, and zero speed of the mixer truck in the basic information of the first complete transportation route is determined as the position of the mixing plant; from the basic information of the mixer truck for the first complete transportation route, reverse rotation information is extracted, and the position of the construction site is determined based on the reverse rotation information; the reverse rotation information is the basic information of the mixer truck that simultaneously meets the conditions of reverse rotation of the mixing drum and a speed of less than a first preset speed;

[0010] When the basic information of the mixer trucks for two or more complete transportation routes is received, the site location is optimized based on the remaining reverse information; the remaining reverse information is the reverse information obtained from the basic information of the mixer trucks for each of the complete transportation routes other than the first complete transportation route.

[0011] According to a method for monitoring the transportation status of a concrete mixer truck provided by the present invention, the location of the construction site is determined based on the reversal information, specifically including:

[0012] Remove the first abnormal information from the reversed information to obtain normal reversed information; the first abnormal information includes reversed information whose information content ratio is less than a preset ratio of the total information content of the reversed information and whose distance from a certain reversed information is greater than a first preset distance.

[0013] Multiple first mixer truck positions are extracted from the real-time mixer truck positions in the normal reversal information at preset fixed time intervals.

[0014] A first rectangle is determined based on the multiple locations of the first mixer trucks; the first rectangle is the rectangle that contains all the locations of the first mixer trucks and has the smallest area.

[0015] The location of the center point of the first rectangle is determined as the location of the construction site.

[0016] According to a method for monitoring the transportation status of a concrete mixer truck provided by the present invention, the step of optimizing the construction site location using other inversion information specifically includes:

[0017] Based on each first reversal information, the second abnormal information in the first reversal information is removed to obtain normal first reversal information; the first reversal information is the reversal information extracted from the basic information of the mixer truck of each complete transportation route from the remaining reversal information; the second abnormal information includes the reversal information whose information content ratio is less than a preset ratio of the total information content of its first reversal information, and whose distance from a certain first reversal information is greater than a second preset distance.

[0018] Based on each normal first reversal information, multiple second mixer truck positions are extracted from the real-time mixer truck positions in the normal first reversal information at the preset fixed time intervals.

[0019] A second rectangle is determined based on the multiple second mixer truck positions in each of the normal first reversal information; the second rectangle is the rectangle that contains all the second mixer truck positions and has the smallest area;

[0020] Calculate the position of the center point of each of the second rectangles;

[0021] The center position of the second rectangle located within the preset circle is determined as the optimized point position of the construction site location; the preset circle is a circle with the construction site location as the center and a preset length as the radius;

[0022] The location of the construction site is optimized using the location of the optimization point.

[0023] According to the present invention, a method for monitoring the transportation status of a concrete mixer truck optimizes the construction site location using the optimized point location, specifically including:

[0024] If there is only one optimization point, then the midpoint between the site location and the optimization point location is selected as the optimized site location.

[0025] If there are two or more optimization points, a division step is performed, and the three positions of each group are combined into a triangle. The centroid position of each triangle is calculated, and the division step is returned until the centroid position is unique and there are no undivided positions. The unique centroid position is determined as the optimized site position. The division step is to divide the undivided positions into groups of three. Each position includes the site position, the optimization point position, and the centroid position.

[0026] According to the present invention, a method for monitoring the transportation status of a concrete mixer truck includes monitoring the following: oil theft, material theft, and travel distance during the transportation process of the concrete mixer truck.

[0027] The present invention also provides a monitoring device for the transportation status of a concrete mixer truck, comprising:

[0028] The location determination system is used to determine the location of the mixing plant and the construction site based on the basic information of the mixer trucks when it receives basic information of at least one complete transportation route; the complete transportation route includes the entire transportation route of a mixer truck from loading to unloading; the basic information of the mixer trucks includes the real-time location of the mixer trucks and the forward and reverse rotation information of the mixing drum;

[0029] The monitoring system is used to monitor the transportation status of the concrete mixer truck based on the location of the mixing plant, the location of the construction site, and the basic information of the mixer truck received in real time.

[0030] The present invention also provides a mixer truck, including a monitoring device for the transport status of the mixer truck as described above.

[0031] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method for monitoring the transport status of a mixer truck as described above.

[0032] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method for monitoring the transport status of a mixer truck as described above.

[0033] The present invention provides a method, device, and truck for monitoring the transportation status of concrete mixer trucks. In the method, upon receiving basic information about at least one complete transportation route of the mixer truck, the location of the mixing plant and the construction site are determined based on this information. The complete transportation route includes the entire route of a mixer truck from loading to unloading. The basic information of the mixer truck includes real-time location of the truck and information on the forward and reverse rotation of the mixing drum. The transportation status of the mixer truck is monitored based on the location of the mixing plant, the location of the construction site, and the real-time received basic information. This invention automatically calculates the location of the mixing plant and the construction site using the real-time location information and the forward and reverse rotation information of the mixing drum reported by the truck itself. Then, based on the calculated location of the mixing plant and the construction site, and combined with the real-time received basic information, the transportation status of the mixer truck is monitored. This eliminates the need for manual input of the mixing plant and construction site location information and the need to connect to an enterprise resource planning (ERP) system, thus solving the technical problems of cumbersome and inefficient manual input and ERP system integration.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0043] The following is combined Figures 1-7 This invention describes a method, a monitoring device, and a concrete mixer truck for monitoring the transportation status of a concrete mixer truck.

[0044] Figure 1 One of the method flowcharts for monitoring the transportation status of a mixer truck provided by the present invention is illustrated.

[0045] like Figure 1 As shown, the method for monitoring the transportation status of a mixer truck provided by the present invention includes:

[0046] 100. When receiving basic information of a mixer truck with at least one complete transportation route, determine the location of the mixing plant and the construction site based on the basic information of the mixer truck.

[0047] The complete transportation route includes the entire transportation route of a mixer truck from loading to unloading; the basic information of the mixer truck includes the real-time location of the mixer truck and the forward and reverse rotation information of the mixing drum.

[0048] It should be noted that the basic information of the mixer trucks is uploaded in real time, but when calculating the location of the mixing plant and the construction site, the calculation can only be performed after the uploaded basic information of the mixer trucks includes the basic information of mixer trucks for at least one complete transportation route.

[0049] Since a single mixer truck may make multiple trips during transportation, or multiple mixer trucks may transport materials together, the aforementioned complete transportation route refers to the entire route from when any mixer truck loads materials at the mixing plant and transports the premixed material to the construction site for unloading until the unloading is completed.

[0050] The real-time location of the mixer truck is the position information at every moment throughout the entire process from the start of loading to the completion of unloading. The forward and reverse rotation information of the mixing drum is used to determine whether the mixer truck is loading or unloading. Forward rotation of the mixing drum may indicate that the mixer truck is loading, while reverse rotation indicates that the mixer truck is unloading.

[0051] 200. Monitor the transportation status of the concrete mixer trucks based on the location of the mixing plant, the location of the construction site, and the real-time basic information of the mixer trucks.

[0052] After calculating the location of the mixing plant and the construction site, and combining this with the basic information of the mixing truck uploaded in real time, the transportation status of the mixing truck can be determined.

[0053] Existing methods of manually entering transportation information are not only cumbersome and inefficient, but also prone to unpredictable errors due to human error. Methods using external systems, on the other hand, lack versatility, requiring customized development for each additional client, and integration with Enterprise Resource Planning (ERP) systems involves business collaborations, making subsequent work extremely complex.

[0054] This invention automatically calculates the location of the mixing plant and the construction site by utilizing basic information about the mixer truck, such as its real-time location and the forward / reverse rotation of the mixing drum, reported from the truck's end. Based on this calculated location, the transportation status of the mixer truck is monitored in conjunction with the real-time received information. This eliminates the need for manual input of mixing plant and construction site location information and avoids integration with enterprise resource planning (ERP) systems, thus solving the technical problems of cumbersome and inefficient manual input and ERP system integration methods.

[0055] Figure 2 The second flowchart illustrates the method for monitoring the transportation status of a mixer truck provided by this invention.

[0056] like Figure 2As shown, in one specific implementation, step 100, based on the basic information of the mixer truck, determines the location of the mixing plant and the construction site, specifically including:

[0057] 110. When only the basic information of the mixer truck for the first complete transportation route is received, the position of the mixer truck that simultaneously meets the conditions of earliest reception time, forward rotation of the mixing drum, and zero speed of the mixer truck in the basic information of the mixer truck for the first complete transportation route is determined as the location of the mixing plant; from the basic information of the mixer truck for the first complete transportation route, the reverse rotation information is extracted, and the construction site location is determined based on the reverse rotation information; wherein, the reverse rotation information is the basic information of the mixer truck that simultaneously meets the conditions of reverse rotation of the mixing drum and a speed of less than a first preset speed.

[0058] 120. When receiving the basic information of the mixer trucks for two or more complete transportation routes, optimize the site location based on the remaining reverse information; wherein, the remaining reverse information is the reverse information obtained from the basic information of the mixer trucks for each of the other complete transportation routes except the first complete transportation route.

[0059] In this invention, the algorithm for determining the location of the mixing plant and the construction site is calculated in real time. When only the basic information of the mixer trucks for the first complete transportation route is received, the location of the mixing plant and the factory is calculated based on this information. This allows for real-time monitoring of the mixer truck transportation status in subsequent operations. If the basic information of the mixer trucks for a second or more complete transportation routes is subsequently received, the construction site location calculated based on the basic information of the mixer trucks for the first complete transportation route is then optimized in real time using the subsequent basic information. Therefore, the construction site location calculated based on the basic information of the mixer trucks for the first complete transportation route in step 110 can be understood as a potential construction site location.

[0060] It should also be noted that many construction sites cannot be displayed on maps or software before construction begins, making it impossible to accurately determine their locations. Furthermore, if concrete mixer trucks engage in material theft during transport, they may also reverse the mixing drum, potentially leading to inaccurate site locations calculated solely based on the reversal information from a single complete transport route. Therefore, site locations need to be optimized using subsequently acquired concrete mixer truck data. Additionally, given the large area covered by the construction sites, the calculated site location in this solution can be considered the site's center. Areas extending outward from this center within a certain radius (e.g., 100 meters) can be considered the site's coverage area.

[0061] Since the loading process of the mixer truck occurs at the very beginning of each transport trip, and the mixing drum rotates clockwise during transport to prevent segregation or even solidification, the location of the mixer truck that simultaneously meets the criteria of earliest receiving time, clockwise rotation of the mixing drum, and zero speed is determined as the location of the mixing plant. Considering practical realities, this invention considers the mixer truck loading to occur only at a fixed location within a single mixing plant. Therefore, unlike unloading by reversing the mixing drum, this invention can accurately calculate the location of the mixing plant based solely on the basic information of the mixer trucks from the first complete transport route, without needing to optimize its location using subsequent mixer truck information. Furthermore, since the mixing plant for loading the mixer trucks is usually already established, meaning its location can be obtained from maps or software, the location of the mixing plant can be accurately determined by combining the calculated location using the basic information of the mixer trucks from the first complete transport route with existing mixing plant locations, without requiring multiple optimizations.

[0062] When calculating the construction site location based on the basic information of the mixer trucks for the first complete transportation route, the calculation is specifically based on the reverse rotation information of the mixer trucks. The reverse rotation information refers to the basic information of the mixer trucks when both the mixing drum reverses direction and the mixer truck's travel speed is less than a first preset speed.

[0063] When the basic information of the mixer trucks for two or more complete transportation routes is received, in order to further optimize the site location calculated from the basic information of the mixer trucks for the first complete transportation route, it is also necessary to calculate the reverse information in the basic information of the mixer trucks for two or more complete transportation routes, so as to use this reverse information to optimize the site location calculated in step 110.

[0064] Figure 3 The third flowchart of the method for monitoring the transportation status of a mixer truck provided by the present invention.

[0065] Figure 4 A schematic diagram illustrating the construction site location calculation principle of the method for monitoring the transportation status of concrete mixer trucks provided by this invention.

[0066] like Figure 3 and Figure 4 As shown, in one optional implementation, step 110, determining the construction site location based on the reversed information, specifically includes:

[0067] 111. Remove the first abnormal information from the reversed information to obtain normal reversed information; the first abnormal information includes reversed information whose information content is less than a preset proportion of the total information content of the reversed information and whose distance from a certain reversed information is greater than a first preset distance.

[0068] When determining the location of a construction site based on the reversed information, it is first necessary to remove any abnormal information from the reversed information.

[0069] Abnormal information in reverse information refers to reverse information that simultaneously meets the following conditions: its proportion is less than a preset percentage (e.g., 10%) of the total information volume of this portion of reverse information, and its distance from any other reverse information is greater than a first preset distance. In other words, this abnormal information not only satisfies the preset percentage requirement that its information volume is less than the total information volume of reverse information, but also that at least one of the distances between this abnormal information and every other reverse information is greater than a first preset distance (e.g., 50 meters). This means that the remaining normal reverse information must satisfy the condition that the distance between any two normal reverse information is less than the first preset distance. Here, the total information volume of reverse information refers to the total amount of information contained in the reverse information.

[0070] 112. Extract multiple first mixer truck positions from the real-time mixer truck positions in the normal reversal information at preset fixed time intervals.

[0071] For example, the normal reverse information is the basic information of the mixer truck from 10:00 to 10:10, meaning that during this period, the mixer truck's mixing drum reverses and travels at a speed lower than the first preset speed. When the preset fixed time interval is 30 seconds, the mixer truck's position is obtained at 10:03, 10:01, 10:01:03, 10:02, 10:02:30, ..., 10:09:30 and 10:10. Figure 4 The black dots in each large rectangle represent the locations of the extracted mixer trucks.

[0072] 113. Determine the first rectangle based on the multiple locations of the first mixer trucks; the first rectangle is the rectangle that includes all the locations of the first mixer trucks and has the smallest area.

[0073] Specifically, the first rectangle can be formed by selecting the positions of the first mixer trucks with the largest longitude, the smallest longitude, the largest latitude, and the smallest latitude.

[0074] 114. Determine the location of the center point of the first rectangle as the construction site location.

[0075] This invention extracts multiple mixer truck locations from the reverse information at preset fixed time intervals, calculates the center point of the smallest first rectangle formed by the multiple mixer truck locations, and determines the center point as the construction site location, thereby improving the accuracy of construction site location calculation.

[0076] Steps 111-114 mainly introduce the method of determining the construction site location using the reversal information extracted from the basic information of the mixer trucks of the first complete transportation route. The following describes the method of optimizing the construction site location using the reversal information extracted from the basic information of the mixer trucks of each of the remaining complete transportation routes other than the first complete transportation route.

[0077] Figure 5 The fourth flowchart of the method for monitoring the transportation status of a mixer truck provided by the present invention.

[0078] like Figure 4 and Figure 5 As shown, as another optional implementation, the site location is optimized using the remaining inversion information, specifically including:

[0079] 121. Based on each first reversal information, remove the second abnormal information from the first reversal information to obtain normal first reversal information; the first reversal information is the reversal information extracted from the basic information of the mixer truck of each complete transportation line from the remaining reversal information; the second abnormal information includes reversal information whose information content ratio is less than the preset ratio of the total information content of its first reversal information and whose distance from a certain first reversal information is greater than the second preset distance.

[0080] Similar to the reversal information extracted from the basic information of the mixer trucks of the first complete transportation route, the remaining reversal information extracted from the basic information of the mixer trucks of the other complete transportation routes also needs to have abnormal information removed before calculation.

[0081] It should be noted that for each of the remaining reverse information, the abnormal information to be removed is determined based on the information content of that specific reverse information and its distance from any other information within that same reverse information. For example, if there is basic information on mixer trucks for three complete transportation routes, then three remaining reverse information are extracted. The determination of abnormal information in the first remaining reverse information is relative to the first reverse information.

[0082] 122. For each normal first reversal information, extract multiple second mixer truck positions from the real-time mixer truck positions in the normal first reversal information at preset fixed time intervals.

[0083] 123. Determine the second rectangle based on the multiple second mixer truck positions in each normal first reversal information; the second rectangle is the rectangle that contains all the second mixer truck positions and has the smallest area.

[0084] 124. Calculate the position of the center point of each second rectangle.

[0085] The solutions in steps 122-124 correspond to the solutions in steps 112-114 above, and the two parts can be referred to each other.

[0086] Figure 4 In the diagram, the smaller rectangle at the center of each large rectangle is the center point.

[0087] 125. Determine the center position of the second rectangle located within the preset circle as the optimized point position of the construction site; the preset circle is a circle with the construction site position as the center and a preset length as the radius.

[0088] Considering that there may be multiple construction sites, when optimizing the construction site location determined in step 114, it is necessary to select data from the same construction site for optimization. Specifically, a preset circle is determined with the construction site location determined in step 114 as the center and a preset length as the radius. Data within the preset circle is then identified as data from the same construction site as the one in step 114.

[0089] 126. Optimize the site location using optimization point locations.

[0090] This invention uses the basic information of mixer trucks from multiple complete transportation routes obtained through multiple transports by mixer trucks to continuously optimize the calculated site location, thereby improving the accuracy of the site location and the mixer truck's driving route.

[0091] As a specific implementation method, step 126 involves optimizing the site location using optimization point locations, specifically including:

[0092] If there is only one optimization point, then the midpoint between the construction site location and the optimization point location is selected as the optimized construction site location.

[0093] If there are two or more optimization points, a partitioning step is performed, and the three positions of each partitioned group are combined into a triangle. The centroid position of each triangle is calculated, and the partitioning step is returned until the centroid position is unique and there are no unpartitioned positions. The unique centroid position is determined as the optimized site position. The partitioning step involves dividing the unpartitioned positions in each location into groups of three. Each location includes the site position, the optimization point position, and the centroid position.

[0094] like Figure 4 As shown, the small rectangle at the center of each large rectangle represents the calculated optimization point. When there are two or more optimization points, they are divided into groups of three, and the three optimization points in each group are grouped into a triangle. (If there are two or one optimization point remaining, these two or one optimization point will proceed to the next round of division.) The centroid of the triangle is calculated (the small triangle within the large triangle is the centroid). At this point, it is determined whether the centroid is unique and whether there are any remaining undivided optimization points. If it is not unique or there are still undivided optimization points, the calculated centroid is considered a new optimization point, and the division step is returned to perform a new round of division and calculation until one centroid remains and there are no remaining undivided optimization points. The last remaining centroid is determined as the optimized site location. Figure 4The solid black triangle in the diagram represents the optimized site location. If one centroid and one undivided optimization point remain, the midpoint between the centroid and the undivided optimization point is determined as the optimized site location.

[0095] It should be noted that in step 125, the center position of the second rectangle not included in the preset circle may belong to the position of other construction sites. For this part of the center position, the construction site position to which it belongs is determined according to the above division method and the subsequent calculation steps of the division steps.

[0096] It should also be emphasized that if the calculated distance between the center of the construction site and the center of the existing construction site does not exceed the third preset distance (e.g., 100 meters), then the center of the existing construction site will be determined as the actual construction site location.

[0097] After calculating the location of the mixing plant and the construction site, this invention can monitor the transportation status of the mixer trucks based on the mixing plant and construction site locations, combined with the real-time received basic information of the mixer trucks, regardless of whether the current location of the construction site is calculated based on the basic information of the mixer trucks for the first complete transportation route or optimized based on the basic information of the mixer trucks for multiple subsequent complete transportation routes.

[0098] In some embodiments, the monitoring content of the mixer truck transportation status includes: oil theft, material theft, and travel distance during the mixer truck transportation process.

[0099] For example, after calculating the location of the mixing plant and the construction site, if it is found that the mixing truck is traveling at a speed lower than the first preset speed and the mixing drum is reversed when it has not reached the construction site, it can be considered that the mixing truck is stealing materials.

[0100] Furthermore, based on the location of the mixing plant and the construction site, combined with real-time received basic information about the mixer trucks, it is possible to determine which segment of a complete transportation route the trucks are traveling on. The transportation route of the mixer trucks can also be monitored to determine whether they are traveling along the normal transportation route.

[0101] This invention utilizes existing basic information about concrete mixer trucks and employs the algorithm provided by this invention to automatically calculate the location of the mixing plant and the factory, thereby automating the calculation of transportation information, improving calculation efficiency and accuracy, and further enhancing the efficiency and accuracy of monitoring transportation status based on transportation information.

[0102] The following describes the monitoring device for the transportation status of a concrete mixer truck provided by the present invention. The monitoring device for the transportation status of a concrete mixer truck described below can be referred to in correspondence with the monitoring method for the transportation status of a concrete mixer truck described above.

[0103] Figure 6The present invention provides a monitoring device for the transportation status of a mixer truck.

[0104] like Figure 6 As shown, the monitoring device for the transportation status of a mixer truck provided by the present invention includes:

[0105] The location determination system is used to determine the location of the mixing plant and the construction site based on the basic information of the mixer trucks when it receives basic information of at least one complete transportation route; the complete transportation route includes the entire transportation route of a mixer truck from loading to unloading; the basic information of the mixer trucks includes the real-time location of the mixer trucks and the forward and reverse rotation information of the mixing drum;

[0106] The monitoring system is used to monitor the transportation status of the concrete mixer trucks based on the location of the mixing plant, the location of the construction site, and the basic information of the mixer trucks received in real time.

[0107] In one specific embodiment, the location determination system in the monitoring device for the transportation status of the mixer truck provided by the present invention includes:

[0108] The location determination subsystem is used to determine the location of the mixing plant when only the basic information of the mixing trucks for the first complete transportation route is received. The mixing trucks whose basic information simultaneously meets the conditions of earliest reception time, forward rotation of the mixing drum, and zero speed are received. The system also extracts reverse rotation information from the basic information of the mixing trucks for the first complete transportation route and determines the construction site location based on the reverse rotation information. The reverse rotation information is the basic information of the mixing trucks whose basic information simultaneously meets the conditions of reverse rotation of the mixing drum and a speed less than a first preset speed.

[0109] The location optimization subsystem is used to optimize the site location by utilizing the remaining reverse information when it receives the basic information of the mixer trucks for two or more complete transportation routes. The remaining reverse information is the reverse information extracted from the basic information of the mixer trucks for each of the other complete transportation routes except the first complete transportation route.

[0110] The location determination subsystem includes:

[0111] The first elimination module is used to eliminate the first abnormal information in the reversed information to obtain normal reversed information; the first abnormal information includes reversed information whose information content ratio is less than a preset ratio of the total information content of the reversed information and whose distance from any normal reversed information is greater than a first preset distance.

[0112] The first extraction module is used to extract multiple first mixer truck positions from the real-time mixer truck positions in the normal reversal information at preset fixed time intervals.

[0113] The first rectangle determination module is used to determine a first rectangle based on the locations of multiple first mixer trucks; the first rectangle is the rectangle that contains all the locations of the first mixer trucks and has the smallest area.

[0114] The site location determination module is used to determine the center point of the first rectangle as the site location.

[0115] The location optimization subsystem specifically includes:

[0116] The second elimination module is used to eliminate the second abnormal information in each first reversal information to obtain normal first reversal information. The first reversal information is the reversal information extracted from the basic information of the mixer truck of each complete transportation line in the remaining reversal information. The second abnormal information includes reversal information whose information content ratio is less than a preset ratio of the total information content of its first reversal information and whose distance from any normal first reversal information is greater than a second preset distance.
