However, due to the tool attributes of working machines, they need to move to different regions for work. The monitoring platforms in different regions may be different.

[0056] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] Combine the following Figures 1 to 5 The monitoring data return method and device of the present invention are described.

[0058] The monitoring data transmission method provided by the present invention can be applied to a server and executed by the server or the software and / or hardware therein. The server can be a physical server or a cloud server. The operating machinery has a networking function, and the server can establish a network connection with each operating machinery. The operating machinery can be non-road machinery such as a crane, an excavator, a pile driver, etc. The scheme of the present invention is described in detail below.

[0059] Figure 1 It is a flow chart of the monitoring data return method provided by the present invention.

[0060] like Figure 1 As shown, this embodiment provides a monitoring data transmission method, which at least includes the following steps:

[0061] Step 101: Acquire target trajectory data of the operating machine.

[0062] In actual applications, a positioning module is provided in the operating machine, and the positioning module is used to locate the operating machine, obtain the position data of the track points of the operating machine and upload it to the server. The position data may be Global Navigation Satellite System (GNSS) data.

[0063] The target trajectory data here may be data of each trajectory point within a time period.

[0064] Step 102: If the target trajectory data of the operating machine indicates that the trajectory of the operating machine passes through boundary lines of more than two target administrative regions, based on the target trajectory data of the operating machine, determine the administrative region in which the operating machine works corresponding to the target trajectory data from among the more than two target administrative regions.

[0065] In practical applications, when monitoring operating machinery, corresponding monitoring platforms are generally set up in different administrative regions to monitor the operating machinery in the administrative region. Therefore, different regions are distinguished based on administrative regions. The target administrative region is the administrative region that forms the boundary line of the trajectory of the operating machinery.

[0066] like Figure 2 In the application scenario shown, the trajectory of the operating machine (shown by the zigzag dotted line in the figure) passes through the boundary line between City A in Province X and City B in Province Y. If the trajectory of the operating machine passes through the boundary lines of more than two target administrative regions, the administrative region where the operating machine works may have changed. At this time, based on the target trajectory data of the operating machine, the administrative region where the operating machine works corresponding to the target trajectory data can be determined from the more than two target administrative regions.

[0067] Step 103: If the administrative area of ​​the work is different from the administrative area corresponding to the current monitoring platform from which the operating machine transmits monitoring data, a switching instruction is sent to the operating machine, wherein the switching instruction is used to instruct the operating machine to switch the monitoring platform from which the monitoring data is transmitted to the monitoring platform corresponding to the administrative area of ​​the work.

[0068] The operating machine can also establish a network connection with different monitoring platforms. In actual applications, since different administrative regions have different monitoring platforms, when working in each administrative region, the monitoring data needs to be transmitted back to the monitoring platform corresponding to the working administrative region. If the determined working administrative region is not the administrative region corresponding to the current monitoring platform to which the operating machine transmits monitoring data, it is necessary to switch the monitoring platform to which the monitoring data needs to be transmitted back. Based on this, the server can send a switching instruction to the operating machine to instruct the operating machine to switch the monitoring platform to which the monitoring data is transmitted back to the monitoring platform corresponding to the working administrative region.

[0069] After receiving the switching instruction from the server, the operating machine switches the monitoring platform for transmitting the monitoring data to the monitoring platform corresponding to the administrative area of ​​the work, and transmits the monitoring data back to the monitoring platform corresponding to the administrative area of ​​the work. Specifically, the operating machine can switch the link for transmitting the monitoring data to the link of the monitoring platform corresponding to the administrative area of ​​the work.

[0070] The monitoring data may include engine emission data of operating machinery and other data that the monitoring platform needs to monitor.

[0071] like Figure 2 As shown, the monitoring platform for transmitting the monitoring data back can be switched from the monitoring platform of City B, Province Y to the monitoring platform of City A, Province X.

[0072] In the present embodiment, since the target trajectory data of the operating machinery can represent that the trajectory of the operating machinery passes through the boundary line of more than two target administrative regions, the administrative region where the operating machinery corresponding to the target trajectory data is determined from the more than two target administrative regions based on the target trajectory data of the operating machinery. If the working administrative region is different from the administrative region corresponding to the current monitoring platform from which the operating machinery transmits monitoring data back, a switching instruction is sent to the operating machinery to instruct the operating machinery to switch the monitoring platform from which the monitoring data is transmitted back to the monitoring platform corresponding to the working administrative region, thereby realizing dynamic switching of monitoring platforms in different administrative regions. The operating machinery can move the working administrative region as needed and transmit the monitoring data back to the monitoring platform corresponding to the working administrative region, thereby expanding the application scope of the operating machinery.

[0073] Based on the above embodiments, the target trajectory data of the operating machinery is used to determine the administrative region in which the operating machinery is working corresponding to the target trajectory data from the two or more target administrative regions. The specific implementation method may include: obtaining statistical data corresponding to each of the target administrative regions and comparing them, and based on the comparison results, determining the working administrative region corresponding to the target trajectory data from the two or more target administrative regions, wherein the statistical data corresponding to the target administrative region is obtained based on data statistics of trajectory points in the target trajectory data that fall into the target administrative region.

[0074] In practical applications, each track point included in the target track data falls into more than two target administrative regions, and the data of each track point falling into each target administrative region can be counted respectively, so as to obtain the statistical data corresponding to each target administrative region. The statistical data corresponding to the target administrative region can reflect the working conditions of the operating machinery in the target administrative region. Therefore, the working administrative region corresponding to the target track data can be accurately determined by comparing the statistical data corresponding to each of the target administrative regions.

[0075] Exemplarily, the obtaining of statistical data corresponding to each of the target administrative regions and comparing the data, and determining, based on the comparison result, from the two or more target administrative regions, the administrative region of the work corresponding to the target trajectory data, may be implemented by:

[0076] The first step is to execute the first selection step: select one target administrative region from the two or more target administrative regions as the first target administrative region for current comparison.

[0077] Step 2: Execute the second selection step: select an unselected target administrative region from the two or more target administrative regions as the second target administrative region for current comparison.

[0078] The third step is to compare the statistical data of the second target administrative area currently being compared with the statistical data of the first target administrative area currently being compared.

[0079] Step 4. If the statistical data of the second target administrative region currently being compared is greater than the statistical data of the first target administrative region currently being compared, the second target administrative region currently being compared is used as the first target administrative region currently being compared, and if the two or more target administrative regions have not been selected, the second selection step is re-executed, and if the two or more target administrative regions have been selected, the final first target administrative region is used as the working administrative region corresponding to the target trajectory data.

[0080] Step 5. If the statistical data of the second target administrative area currently being compared is less than or equal to the statistical data of the first target administrative area currently being compared, and the two or more target administrative areas have not been selected, re-execute the second selection step; if the two or more target administrative areas have been selected, use the final first target administrative area as the working administrative area corresponding to the target trajectory data.

[0081] For example, the two or more target administrative regions include target administrative region a, target administrative region b and target administrative region c. First, select target administrative region a as the first target administrative region, select target administrative region b as the second target administrative region, compare the statistical data of target administrative region a with the statistical data of target administrative region b, if the statistical data of target administrative region b is greater than that of target administrative region a, then use target administrative region b as the first target administrative region, continue to select target administrative region c as the second target administrative region, compare the statistical data of target administrative region b with the statistical data of target administrative region c, if the statistical data of target administrative region c is greater than that of target administrative region b, then use target administrative region c as the first target administrative region. At this time, the target administrative regions have been selected, and the final first target administrative region, i.e., target administrative region c, becomes the administrative region of the work corresponding to the target trajectory data.

[0082] In this embodiment, the administrative area where the operating machine works can be quickly determined by sequentially comparing the statistical data of each target administrative area.

[0083] The statistical data corresponding to the target administrative area may include at least one of the following statistical values:

[0084] First, a first statistical value, which is the number of trajectory points falling into the target administrative area.

[0085] In practical applications, there are generally more trajectory points in the working administrative area. Therefore, the number of trajectory points falling in the target administrative area can be used as a factor to measure the working administrative area.

[0086] Second, a second statistical value, which is the cumulative working time of the operating machinery in the target administrative area based on the total working time contained in the data of each trajectory point falling in the target administrative area.

[0087] The data of the track points include the total working time of the operating machine, which refers to the total working time of the operating machine after it is powered on for the first time.

[0088] The statistical method of the cumulative working time of the operating machinery in the target administrative area may include: based on the reporting order of the data of each trajectory point in the target administrative area, determining at least one sub-trajectory, each sub-trajectory containing multiple continuous trajectory points; for each sub-trajectory, starting from the data of the second trajectory point of the sub-trajectory, calculating the first difference between the total working time contained in the data of each trajectory point and the total working time contained in the data of the previous trajectory point, summing the first differences corresponding to each trajectory point to obtain the cumulative working time corresponding to the sub-trajectory; summing the cumulative working time corresponding to each sub-trajectory to obtain the cumulative working time of the operating machinery in the target administrative area.

[0089] The first difference reflects the change in the total working time of the operating machinery between adjacent trajectory points, so the cumulative working time of the operating machinery in the target administrative area can be obtained through the first difference.

[0090] For example, the target administrative area a falls into trajectory point a1 and trajectory point a2, the total working time contained in the data of trajectory point a1 is 100 hours and the total working time contained in the data of trajectory point a2 is 101 hours, then the cumulative working time of the operating machinery in the target administrative area is 1 hour.

[0091] Third, a third statistical value, which is a cumulative reporting time of the operating machinery in the target administrative area, obtained based on the reported timestamp data contained in the data of each trajectory point falling in the target administrative area.

[0092] The timestamp data represents the time when the data of the track point is reported. The cumulative reporting time of the operating machine in the target administrative area refers to the total time of the operating machine reporting the track point in the target administrative area.

[0093] The statistical method of the cumulative reporting time of the operating machinery in the target administrative area may include: based on the reporting order of the data of each trajectory point in the target administrative area, determining at least one sub-trajectory, each sub-trajectory containing multiple continuous trajectory points; for each sub-trajectory, starting from the data of the second trajectory point of the sub-trajectory, calculating the second difference between the timestamp data contained in the data of each trajectory point and the timestamp data contained in the data of the previous trajectory point, summing the second differences corresponding to each trajectory point, and obtaining the cumulative reporting time corresponding to the sub-trajectory; summing the cumulative reporting time corresponding to each sub-trajectory to obtain the cumulative reporting time of the operating machinery in the target administrative area.

[0094] The second difference reflects the time interval between reports of adjacent trajectory points, so the second difference can be used to obtain the cumulative reporting time of the operating machinery in the target administrative area.

[0095] Still taking an example, the target administrative area a falls into trajectory point a1 and trajectory point a2, the timestamp data contained in the data of trajectory point a1 is 16 o'clock, and the timestamp data contained in the data of the adjacent trajectory point a2 is 17 o'clock, then the cumulative reporting time of the operating machinery in the target administrative area is 1 hour.

[0096] Fourth, a fourth statistical value, which is the sum of distances from each trajectory point in the target administrative area to the boundary line obtained based on the position data contained in the data of each trajectory point in the target administrative area.

[0097] The boundary line here refers to a boundary line formed by the first target administrative region and the second target administrative region currently being compared. The distance from the trajectory point falling in the target administrative region to the boundary line is the shortest distance from the trajectory point to the boundary line.

[0098] The greater the sum of the distances from the trajectory points falling within the target administrative area to the boundary line, the higher the possibility that the operating machine will work in the target administrative area. Therefore, it can be used as a factor to measure the administrative area of ​​work.

[0099] Fifth, a fifth statistical value, which is the distance from the center of a geometric figure formed by each trajectory point falling in the target administrative area to a boundary line obtained based on the position data contained in the data of each trajectory point falling in the target administrative area.

[0100] Similarly, the boundary line here refers to a boundary line formed by the first target administrative region and the second target administrative region currently being compared. The distance from the center of the geometric figure formed by each track point falling in the target administrative region to the boundary line is the shortest distance from the center to the boundary line.

[0101] The greater the distance from the center of the geometric figure formed by the trajectory points falling in the target administrative area to the boundary line, the higher the possibility that the operating machinery will work in the target administrative area. Therefore, it can be used as a factor to measure the administrative area of ​​work.

[0102] In this embodiment, statistics are collected on the above-mentioned various factors to more accurately determine the administrative area where the operating machinery works.

[0103] Based on this, the statistical data of the second target administrative area currently being compared is compared with the statistical data of the first target administrative area currently being compared, and its specific implementation method may include:

[0104] If the statistical data corresponding to the target administrative region includes a statistical value, a statistical value included in the statistical data of the second target administrative region currently being compared is compared with a statistical value included in the statistical data of the first target administrative region currently being compared.

[0105] If the statistical data corresponding to the target administrative area includes multiple statistical values, weighted summation is performed on the multiple statistical values ​​contained in the statistical data of the first target administrative area currently being compared to obtain a first weighted summation value, weighted summation is performed on the multiple statistical values ​​contained in the statistical data of the second target administrative area currently being compared to obtain a second weighted summation value, and the second weighted summation value is compared with the first weighted summation value.

[0106] When performing weighted summation, the weight of each statistical value can be set according to actual conditions.

[0107] In this embodiment, the comparison can be based on one statistical value as needed to more quickly determine the administrative area of ​​the work, or a combination of multiple statistical values ​​can be used for comparison to more accurately determine the administrative area of ​​the work.

[0108] In an exemplary embodiment, the target trajectory data of the operating machine is used to determine the administrative region where the operating machine works corresponding to the target trajectory data from the two or more target administrative regions. The specific implementation method may include: based on the position data contained in the data of each trajectory point in the target trajectory data, determining the target administrative region where the center of the geometric figure formed by each trajectory point is located as the working administrative region corresponding to the target trajectory data. In actual applications, the center of the geometric figure formed by each trajectory point in the trajectory of the operating machine generally falls in the working administrative region. Therefore, the administrative region where the operating machine works can be quickly determined by the target administrative region where the center of the geometric figure formed by each trajectory point is located.

[0109] Based on the above embodiment, before determining the administrative region where the operating machinery works corresponding to the target trajectory data from the two or more target administrative regions based on the target trajectory data of the operating machinery, the method provided in this embodiment may also include: determining the target administrative region where each trajectory point falls respectively based on the position data contained in the data of each trajectory point in the target trajectory data; if the number of the determined target administrative regions is multiple, determining that the trajectory of the operating machinery passes through the boundary line of the two or more target administrative regions. If the trajectory points in the target trajectory data fall into more than two administrative regions, it means that the operating machinery has passed the boundary of the administrative region and may be working across regions. It is necessary to determine whether the administrative region where the operation is carried out has changed, so as to accurately transmit the monitoring data back to the monitoring platform corresponding to the administrative region where the operation is carried out.

[0110] Based on the above embodiments, the specific implementation of obtaining the target trajectory data of the operating machine may include: obtaining the original trajectory data of the operating machine; deleting the invalid data of each trajectory point in the original trajectory data to obtain the valid data of each trajectory point; using the valid data of each trajectory point as the target trajectory data. The invalid data of each trajectory point includes at least one of the following: the data of the trajectory point within the preset startup time of the operating machine; the data of the trajectory point of the operating machine in the non-operating state; the data of the trajectory point that has drifted.

[0111] The data of a drifting track point refers to the data of a track point where the position difference between the position data contained in the data of the track point and the position data contained in the data of the previous valid track point is greater than or equal to the difference threshold. The difference threshold can be set to 0.5 to 1 km. Since the positioning technology used by the positioning module in the operating machinery may be affected by environmental factors such as weather conditions, high-rise buildings, and the number of satellites, the track point may drift. The data of such a track point is invalid and can be deleted.

[0112] When the operating machine is in operation, the engine speed is not zero. The data of the track point can include the engine speed. If the engine speed is zero, it indicates that the operating machine is not in operation. If the engine speed is not zero, it indicates that the operating machine is in operation. Since the monitoring platform requires the return of monitoring data of the operating machine in operation, the data of the track point in the non-operation state can be regarded as invalid track point data and can be deleted.

[0113] When the operating machine is just turned on, the positioning module is not stable and the drift is very obvious. The data of these track points within the preset startup time can also be regarded as invalid track point data and can be deleted. The preset time can be set according to the actual situation. For example, the preset time does not exceed 5 minutes.

[0114] In this embodiment, the data of invalid trajectory points are deleted, and the data of valid trajectory points are retained, thereby improving the quality of the target trajectory data.

[0115] Based on the above embodiments, the target trajectory data of the operating machinery may be obtained in a specific implementation method including: obtaining the target trajectory data of the operating machinery within the period with a preset duration as a cycle. In practical applications, the specific value of the preset duration can be set according to actual conditions. Exemplarily, the target trajectory data of the operating machinery within a day may be obtained with a day as a cycle. Specifically, the target trajectory data of the operating machinery within the previous day may be obtained every day. Based on this, the administrative area where the operating machinery corresponding to the target trajectory data of the previous day works may be obtained every day.

[0116] Correspondingly, the specific implementation method of sending a switching instruction to the operating machine may include: if the working area corresponding to the target trajectory data in a plurality of consecutive cycles is different from the administrative area corresponding to the current monitoring platform from which the operating machine transmits monitoring data, sending a switching instruction to the operating machine. Exemplarily, the number of cycles n of the plurality of cycles is at least 3, where n is a positive integer. If the cycle is day, and the working area corresponding to the target trajectory data for n consecutive days is different from the administrative area corresponding to the current monitoring platform from which the operating machine transmits monitoring data, sending a switching instruction to the operating machine. In this way, frequent switching of the working administrative area can be avoided.

[0117] If each track point in the target track data in any of the multiple cycles falls into the administrative area corresponding to the current monitoring platform that transmits the monitoring data back, no switching instruction is sent. In actual applications, the operating machinery may cross regions in some cycles, but quickly return to the original region. At this time, the monitoring platform may not be switched, which can further avoid frequent switching of the working administrative area.

[0118] Based on the above embodiments, before sending a switching instruction to the working machine, the method provided in this embodiment may also include: if at least one application for returning monitoring data installed in the working machine does not correspond to the administrative area of ​​the work, installing or upgrading the application for returning monitoring data in the working machine.

[0119] In actual applications, an application corresponding to the monitoring platform is set in the operating machine to transmit monitoring data back to the monitoring platform. Different monitoring platforms may have different corresponding applications. Based on this, the server can obtain information about at least one application installed in the operating machine that transmits monitoring data back. The information of the application may include the name of the application, the version number, the fields included in the transmitted monitoring data, the communication protocol used, the access address of the monitoring platform, etc. If the application corresponding to the administrative area of ​​the work is not installed in the operating machine, then the information of at least one application installed in the operating machine that transmits monitoring data back does not contain the information of the application corresponding to the administrative area of ​​the work, and it is determined that the application corresponding to the administrative area of ​​the work is not installed in the operating machine. At this time, the application that transmits monitoring data back in the operating machine can be installed or upgraded.

[0120] Specifically, the application for transmitting monitoring data back in the operating machine may be installed or upgraded through Over-the-Air Technology (OTA).

[0121] In this embodiment, the application corresponding to the monitoring platform corresponding to each administrative area can be dynamically installed or upgraded to meet the data feedback requirements of the monitoring platforms of different administrative areas.
