[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] It can be understood that the terms "first", "second", etc. used in the present application can be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first xx script can be called the second xx script, and similarly, the second xx script can be called the first xx script.

[0030] Figure 1 Schematic diagram of a wetland patrol coordinate backhaul system provided by an embodiment of the present application. As Figure 1 shown, in this system, it includes a terminal 110 and a computer device 120.

[0031] The computer device 120 can be an independent physical server or terminal, or a server cluster composed of multiple physical servers, and can be a cloud server that provides basic cloud computing services such as cloud servers, cloud databases, cloud storage, and CDN.

[0032] The terminal 110 can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal 110 and the computer device 120 can be connected through a network, and the present application does not make any restrictions here.

[0033] In one embodiment, as Figure 2 shown, a wetland patrol coordinate backhaul method. In this embodiment, this method is applied to the above-mentioned Figure 1 terminal device 110 as an example for description. The method includes:

[0034] Step S202: Obtain the current location information.

[0035] Among them, the current location of the terminal can be obtained by sending a location acquisition request to various map application service providers.

[0036] Step S204: Determine motion information based on the current position information, the first position information, and the second position information in the historical positions.

[0037] Among them, each time the terminal transmits the position back, it will record both the position information and the acquisition time, so there will be historical position information. The first position information is the position information with the acquisition time closest to the current time, and the second position information is the position information in the historical positions with the acquisition time closest to the acquisition time of the first position information. Therefore, the current position information, the first position information, and the second position information are three adjacent points on the map. Since when recording the position information, both the position information and the corresponding time are recorded as historical position information, the motion trajectory and motion speed, that is, the motion information, can be determined based on the historical position information.

[0038] Step S206: Transmit the current position information back and determine the next transmission time according to the motion information.

[0039] Among them, when uploading the position information to the server, the position information acquisition time will also be uploaded to the server. Then, based on the calculated motion information, it is judged whether it is necessary to adopt a relatively frequent upload frequency, that is, a shorter upload time interval. When it is judged that a relatively frequent upload frequency is not required, it is changed to adopt a relatively loose upload frequency (that is, a longer upload time interval) to reduce the power consumption of the terminal, thereby extending the battery life of the terminal.

[0040] In one embodiment, as Figure 3 shown, step S204 includes:

[0041] Step S302: Determine the motion direction change rate based on the current position information, the first position information, and the second position information in the historical positions.

[0042] Among them, since the current position information, the first position information, and the second position information in the historical positions are essentially three coordinate points transmitted back successively most recently, the motion direction can be determined based on two adjacent coordinate points, and the motion direction change rate can be determined according to the change of the motion direction.

[0043] Step S304: Determine the motion speed change rate based on the current position information, the first and second position information in the historical positions, and the acquisition time of each position information.

[0044] Among them, since the corresponding acquisition time is also recorded when recording the position information, the distance between two adjacent coordinate points can be determined according to the difference between the two, the motion time can be determined according to the corresponding acquisition time of the two, so the motion speed can be calculated, and then the change rate of the motion speed can be determined according to the difference between the motion speeds.

[0045] In one embodiment, step S302 includes:

[0046] Step S402: Determine the first motion direction information according to the current position information and the first position information.

[0047] Wherein, assuming that the coordinates of the current position information are (x0, y0) and the coordinates of the first position information are (x1, y1), then the first motion direction information k1 = (y1 - y0) / (x1 - x0).

[0048] Step S404: Determine the second motion direction information according to the first position information and the second position information.

[0049] Wherein, assuming that the coordinates of the first position information are (x1, y1) and the coordinates of the second position information are (x2, y2), then the second motion direction information k2 = (y2 - y1) / (x2 - x1).

[0050] Step S406: Determine the motion direction change rate according to the first motion direction information and the second motion direction information.

[0051] Wherein, after obtaining the first and second motion direction information, the absolute value of the difference between the two can be used as the motion direction change rate, that is, the motion direction change rate Δk = |k2 - k1|. Using the slope to record the motion direction between adjacent two coordinate points can, on the one hand, make the solution process of the motion direction change rate faster, and on the other hand, can also reduce the storage resources occupied by recording the motion direction.

[0052] In one embodiment, as Figure 5 shown, step S304 includes:

[0053] Step S502: Determine the first motion speed according to the current position information, the first position information, the acquisition time corresponding to the current position information and the first position information.

[0054] Wherein, assuming that the coordinates of the current position information are (x0, y0) and its acquisition time is t0; the coordinates of the first position information are (x1, y1) and its acquisition time is t1, then the first motion speed v1 = ((x1 - x0) 2 +(y1 - y0) 2 ) 1 / 2 / (t1 - t0).

[0055] Step S504: Determine the second motion speed according to the first position information, the second position information, the acquisition time corresponding to the first position information and the second position information.

[0056] Among them, assuming that the coordinates of the first position information are (x1, y1), and its acquisition time is t1; the coordinates of the second position information are (x2, y2), and its acquisition time is t2, then the second movement speed v2 = ((x2 - x1) 2 +(y2 - y1) 2 ) 1 / 2 / (t2 - t1).

[0057] Step S506: Determine the change rate of the movement speed according to the first movement speed and the second movement speed.

[0058] Among them, after obtaining the first and second movement speed information, the absolute value of the difference between the two can be used as the change rate of the movement direction, that is, the change rate of the movement direction Δv = |v2 - v1|.

[0059] In one embodiment, as Figure 6 shown, step S206 includes:

[0060] Step S602: Determine whether the change rate of the movement direction is less than a preset direction change threshold and the change rate of the movement speed is less than a preset speed change threshold; if so, execute step S604; if not, execute step S606.

[0061] Among them, the change rate of the movement direction being less than the preset direction change threshold indicates that the movement path at this time is a straight line, otherwise, it indicates that there is a curve in the movement path between the coordinates of two adjacent transmissions. The change rate of the movement speed being less than the preset speed change threshold indicates that everything is normal in this section of the path, otherwise, it indicates that there is a curve in the movement path between the coordinates of two adjacent transmissions, or the patrol personnel have discovered an abnormal situation during the patrol. Those skilled in the art can select the specific values of the direction change threshold and the speed change threshold according to the actual situation, and the present application does not make specific limitations here.

[0062] Step S604: Determine the next transmission time as the current transmission interval plus a preset step length.

[0063] Among them, when it is determined that there are no curves or abnormal conditions in the current patrol path, a relatively loose position upload strategy can be adopted, so the upload time interval can be increased. That is, the next upload time is the current upload time plus a preset step size. For example, assuming that the initial upload time interval is 10s, the step size is 2s, and the current upload time interval is also 10s, then under normal circumstances, the next upload time interval is 12s, and the next upload time interval after that is 14s, gradually extending the upload time interval, making the upload of positions less frequent, thereby reducing the power consumption and system resource occupancy required for position upload and extending the battery life of the terminal. Of course, the upload time interval will not be extended indefinitely. After the upload time interval is equal to the preset maximum upload time interval, the upload time interval will no longer increase, and this maximum upload time interval can be freely controlled by those skilled in the art according to the actual situation, and this application does not make specific restrictions here.

[0064] Step S606: Determine the next upload time as the preset initial upload interval.

[0065] Among them, when it is determined that there is a curve or abnormal patrol speed in the current patrol path, the upload time interval is restored to the initial upload time interval, that is, a relatively frequent upload strategy is adopted to obtain more position information, so as to record this section of the journey in detail for subsequent processing or analysis.
