Technical Field

[0001] This invention relates to the field of positioning technology, and in particular to a method, apparatus, electrical equipment, and storage medium for marking the location of equipment deployment. Background Technology

[0002] With the development of positioning technology, positioning-related business needs are constantly being discovered. Various businesses have increasingly higher requirements for positioning accuracy and real-time performance. To improve positioning accuracy, the deployment accuracy of positioning base station equipment is also very important. This is because positioning base station equipment sends information such as the distance measurement, angle, and signal strength of the positioning device to the positioning engine. Based on this data and the deployment location of the positioning base station, the positioning engine calculates the precise location of the positioning device.

[0003] Currently, the deployment of positioning base stations is mainly accomplished through engineering methods. It requires manual verification of the equipment location and marking and configuring the corresponding location on the electronic map of the positioning engine. This process requires multiple human interventions, which can easily lead to marking errors and inaccurate system positioning. Summary of the Invention

[0004] This invention provides a method, apparatus, electrical equipment, and storage medium for marking the deployment location of equipment, in order to solve the problem of inaccurate positioning caused by incorrect marking of equipment location.

[0005] According to one aspect of the present invention, a method for marking the deployment locations of devices is provided, for marking the deployment locations of multiple deployed devices on an electronic map, comprising:

[0006] Once the equipment deployment is complete, obtain the ranging information of each of the devices, which is the distance information between the device and other devices.

[0007] A map coordinate system is constructed based on any of the ranging information, and the initial position information of each device in the map coordinate system is determined based on the ranging information of each device.

[0008] During the calibration of the initial position information of each device, for the first device, the calibration position information of the first device is determined based on the known position information of the second device;

[0009] Continue to acquire new ranging information for each of the aforementioned devices, and determine the calibration position information and the initial position information of the first device based on the new ranging information, until the position information of multiple devices meets the calibration conditions, and map the position information of multiple devices that meet the calibration conditions onto an electronic map;

[0010] Wherein, the first device is any one of a plurality of devices, and the second device is any other device besides the first device; the known location information of the second device is the initial location information or calibration location information of the second device.

[0011] According to another aspect of the present invention, a device for marking the deployment location of a device is provided, applied to a positioning engine, comprising:

[0012] The ranging information acquisition module is used to acquire the ranging information of each of the devices after the devices are deployed, wherein the ranging information is the distance information between the device and other devices;

[0013] The initial position information determination module is used to construct a map coordinate system based on any of the ranging information, and to determine the initial position information of each of the devices in the map coordinate system based on the ranging information of each of the devices.

[0014] The calibration position information determination module is used to determine the calibration position information of the first device based on the known position information of the second device during the calibration process of the initial position information of each device.

[0015] The location information calibration module is used to continue acquiring new ranging information for each of the devices, and to determine the calibration location information and the initial location information of the first device based on the new ranging information, until the location information of multiple devices meets the calibration conditions, and to map the location information of the multiple devices that meet the calibration conditions onto an electronic map; wherein, the first device is any one of the multiple devices, and the second device is any other device besides the first device; the known location information of the second device is the initial location information or calibration location information of the second device.

[0016] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0017] At least one processor; and

[0018] A memory communicatively connected to the at least one processor; wherein,

[0019] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the device deployment location marking method according to any embodiment of the present invention.

[0020] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the device deployment location marking method according to any embodiment of the present invention.

[0021] The technical solution of this invention involves acquiring distance information for each device after deployment, where the distance information represents the distance between the device and other devices. A map coordinate system is constructed based on any distance information, and the initial position information of each device in the map coordinate system is determined based on the distance information of each device. During the calibration of the initial position information of each device, for the first device, the calibration position information of the first device is determined based on the known position information of the second device. New distance information for each device is then acquired, and the calibration position information and initial position information of the first device are judged based on the new distance information until the position information of multiple devices meets the calibration conditions. The position information of the multiple devices that meet the calibration conditions is then mapped onto an electronic map. Here, the first device is any one of the multiple devices, and the second device is any other device besides the first device. The known position information of the second device is either its initial position information or its calibration position information. This allows for precise marking of the deployed device positions on the electronic map, avoiding inaccurate positioning due to incorrect marking, improving the accuracy of device deployment position marking, and thus improving positioning accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] It should be noted that the terms "first device," "second device," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0029] Example 1

[0030] Figure 1 This is a flowchart of a method for marking the deployment location of equipment according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of marking multiple deployed base station-type equipment on an electronic map. The method can be executed by a device for marking the deployment location of equipment, which can be implemented in hardware and / or software and can be configured in a positioning engine. Figure 1 As shown, the method includes:

[0031] S110. Once the equipment deployment is complete, obtain the distance measurement information for each of the devices, wherein the distance measurement information is the distance information between the device and other devices.

[0032] Here, the distance measurement information for each device refers to the distance information between that device and other devices obtained through mutual distance measurement. It can be understood that since each pair of devices measures distance from each other, there are two sets of distance measurement information between the two devices: the distance measurement information of device A to device B and the distance measurement information of device B to device A.

[0033] It should be noted that the device mentioned in this embodiment is a positioning base station device. Positioning base station devices need to have mutual ranging function, or be able to enter a certain working mode in which base station devices can measure distance to each other.

[0034] Based on the above embodiments, optionally, obtaining the ranging information of each of the devices includes: for any device, measuring the distance through the interaction between the device and other devices to obtain the ranging information of the device.

[0035] In this embodiment, for any device, distance measurement can be performed through interaction with other devices. For example, device A sends a signal, and device B receives the signal from device A. Device B measures the time from receiving the signal to its arrival. Based on the formula speed = distance / time, device B can calculate the distance between itself and device A. The signal is typically a wireless signal, such as a radio frequency (RF) or ultrasonic signal. The speed of the signal is generally known; for example, the speed of radio waves is the speed of light.

[0036] S120. Construct a map coordinate system based on any of the ranging information, and determine the initial position information of each device in the map coordinate system based on the ranging information of each device.

[0037] The initial position information is a rough estimate determined by the ranging information of each device in a map coordinate system. It is understood that signal transmission is affected by the external environment, and the ranging information has a certain degree of error. Therefore, the initial position information determined based on the ranging information is a rough estimate of the device's position. In this embodiment, a map coordinate system is constructed, and the initial position information of each device in the map coordinate system can be determined based on the ranging information of each device.

[0038] Based on the above embodiments, optionally, the map coordinate system includes a first coordinate system device, a second coordinate system device, and a third coordinate system device; wherein, the first coordinate system device is located at the origin of the map coordinate system, the second coordinate system device is located on the axis of the map coordinate system, and the relative position of the third coordinate system device with the first coordinate system device and the second coordinate system device is known.

[0039] Among them, the first coordinate system device, the second coordinate system device, and the third coordinate system device are selected from multiple devices to construct the map coordinate system. The first coordinate system device is located at the origin of the map coordinate system, and its position information can be represented as (0,0). The second coordinate system device is located on the axis of the map coordinate system, and its position information can be represented as (0,y1) or (x1,0). The relative position of the third coordinate system device with the first and second coordinate system devices is known. The position information of the third coordinate system device can be determined based on the coordinates of the first and second coordinate system devices, the distance measurement information of the first and second coordinate system devices relative to the third coordinate system device, and the relative position of the third coordinate system device with the first and second coordinate system devices. The position information of the third coordinate system device can be represented as (x2,y2).

[0040] For example, a map coordinate system with units of centimeters is constructed. A first coordinate system device, Dev0, is selected or specified and positioned at the origin (0, 0) of the map coordinate system. Further, a second coordinate system device, Dev1, which is closest to the first coordinate system device Dev0, is selected and positioned on the Y-axis. The coordinates of the second coordinate system device Dev1 are (0, y1), thus determining the Y-axis direction of the map coordinate system. It is understood that if the second coordinate system device Dev1 is positioned on the X-axis, the same applies to the Y-axis, which will not be elaborated here. Further, a third coordinate system device, Dev3, is selected. Based on the distance measurement information of Dev1 and Dev2 to Dev3 and the coordinates of Dev1 and Dev2, two intersection points can be determined on the map coordinate system. Then, based on the relative positions of the third coordinate system device with the first and second coordinate system devices, the coordinate point of the third coordinate system device Dev3 can be determined from the two intersection points, denoted as (x2, y2).

[0041] Based on the above embodiments, optionally, determining the initial position information of each device in the map coordinate system based on the ranging information of each device includes: for any device other than the first coordinate system device, the second coordinate system device, and the third coordinate system device, determining the initial position information of the device in the map coordinate system based on the ranging information between the device and the first coordinate system device, the ranging information between the device and the second coordinate system device, the ranging information between the device and the third coordinate system device, and the position information of the first coordinate system device, the second coordinate system device, and the third coordinate system device.

[0042] In this embodiment, when the positions of the first coordinate system device, the second coordinate system device, and the third coordinate system device are known, for any device other than the first coordinate system device, the initial position information of the device in the map coordinate system can be determined using the least squares method based on the distance measurement information between the device and the first coordinate system device, the distance measurement information between the device and the second coordinate system device, the distance measurement information between the device and the third coordinate system device, and the position information of the first coordinate system device, the second coordinate system device, and the third coordinate system device.

[0043] For example, assuming the coordinates of the first coordinate system device, the second coordinate system device, and the third coordinate system device in the map coordinate system are (0,0), (0,y1), and (x2,y2), respectively, the following equation can be obtained:

[0044] Based on the distance formula, the following three equations can be obtained:

[0045] dist1 = sqrt((x-0)^2 + (y-0)^2)

[0046] dist2=sqrt((x-0)^2+(y–y1)^2)

[0047] dist3=sqrt((x–x2)^2+(y–y2)^2)

[0048] Transforming the above three equations into mathematical expressions, we get:

[0049] eq1:Eq(sqrt((x-0)**2+(y-0)**2),0)

[0050] eq2:Eq(sqrt((x-0)**2+(y–y1)**2),0)

[0051] eq3:Eq(sqrt((x–x2)**2+(y–y2)**2),0)

[0052] Solving the above system of equations using the least squares method yields the coordinates of any device other than the first coordinate system device, the second coordinate system device, and the third coordinate system device.

[0053] Where dist1, dist2, and dist3 represent the distance measurement information between the device and the device in the first coordinate system, the distance measurement information between the device and the device in the second coordinate system, and the distance measurement information between the device and the device in the third coordinate system, respectively.

[0054] S130. During the calibration of the initial position information of each device, for the first device, the calibration position information of the first device is determined based on the known position information of the second device.

[0055] In this context, the first device refers to any one of multiple devices, and the second device refers to any device other than the first device. The known location information of the second device refers to its initial location information or calibration location information. The known location information of the second device refers to its current location information. It can be understood that if the device's location information has been calibrated, then the device's known location information is the calibration location information; otherwise, the device's known location information is the initial location information. In addition, the location information of the same device may have been calibrated multiple times, and the latest calibration location information is taken as the device's known location information.

[0056] In this embodiment, during the calibration of the initial position information of each device, for the first device, the calibration position information of the first device is determined by the least squares method based on the known position information of the second device. The calibration position information is used to calibrate the known position information of the device. It should be noted that step S130 can be executed sequentially with step S140, or in parallel with step S140.

[0057] S140. Continue to acquire new ranging information for each of the devices, and determine the calibration position information and the initial position information of the first device based on the new ranging information, until the position information of multiple devices meets the calibration conditions, and map the position information of multiple devices that meet the calibration conditions onto the electronic map.

[0058] The new ranging information refers to multiple sets of ranging information collected by each device within a preset time period. Specifically, the preset time period is set by those skilled in the art according to their needs and is not limited here. In this embodiment, new ranging information from each device is continuously acquired. The calibration position information and initial position information of the first device can be determined based on the new ranging information until the position information of multiple devices meets the calibration conditions. The position information of the multiple devices that meet the calibration conditions is then mapped onto an electronic map. The calibration conditions refer to the conditions under which the device's position information meets the calibration requirements.

[0059] In some embodiments, optionally, after acquiring new ranging information for each device, the two ranging information between any two devices can be detected. If the absolute value of the difference between the two ranging information is greater than a preset fluctuation threshold, the two ranging information are filtered out.

[0060] Based on the above embodiments, optionally, the step of determining the calibration position information and the initial position information of the first device based on the new ranging information until the position information of multiple devices meets the calibration conditions includes: iteratively executing the following steps until the position information of multiple devices meets the calibration conditions: for the first device: determining the first variance and data corresponding to the first device based on the new ranging information and the known position information of each device; determining the second variance and data corresponding to the first device based on the new ranging information, the calibration position information of the first device, and the known position information of the second device; determining the variance and difference corresponding to the first device based on the first variance and data and the second variance and data; and determining the position information of the device that meets the determination conditions based on the variance and difference of each of the multiple devices, and adjusting the position information of the device that meets the determination conditions to the calibration position information.

[0061] Here, the first variance and data refer to the variance and data corresponding to the first device before adjustment, and the second variance and data refer to the variance and data corresponding to the first device after adjustment. This embodiment can be understood as determining the first variance and data of each device before adjustment and the second variance and data of each device after adjustment, adjusting the position information of devices whose variance and difference values ​​meet the judgment conditions, and repeating the above steps until the position information of each device meets the calibration conditions.

[0062] Specifically, the following steps are performed iteratively until the location information of multiple devices meets the calibration conditions:

[0063] 1) For the first device, determine the first variance and data corresponding to the first device based on the new ranging information of each device and the known position information of each device;

[0064] 2) Determine the second variance and data corresponding to the first device based on the new ranging information of each device, the calibration position information of the first device, and the known position information of the second device;

[0065] 3) Determine the variance and difference value corresponding to the first device based on the first variance and data and the second variance and data corresponding to the first device; it can be understood that the variance and difference value corresponding to any device can be obtained through steps 1-3;

[0066] 4) Based on the variance and difference of each device among multiple devices, the position information of the devices that meet the judgment conditions is adjusted to the calibration position information.

[0067] The determination criterion can be the device with the largest difference in variance and difference among all devices. Specifically, the variances and differences among multiple devices can be sorted, and the location information of the device with the largest variance and difference among all devices can be adjusted to the calibration location information. The calibration condition can be that the variance and difference of the device with the largest difference in variance and difference among all devices is less than a preset variance and difference threshold.

[0068] Based on the above embodiments, optionally, determining the first variance and data corresponding to the first device based on the new ranging information of each device and the known location information of each device includes: determining the mean ranging between the first device and the second device based on the new ranging data of the first device and the new ranging data of the second device; determining the first distance between the first device and the second device based on the known location information of the first device and the known location information of the second device; and determining the first variance and data corresponding to the first device based on the mean ranging between the first device and the second device and the first distance between the first device and the second device.

[0069] Wherein, the first distance refers to the distance between the first device and the second device before adjustment. In this embodiment, the mean distance between the first device and the second device is determined based on the new distance measurement data of the first device and the new distance measurement data of the second device; the first distance between the first device and the second device is determined based on the known location information of the first device and the known location information of the second device; furthermore, the corresponding first variance and data of the first device are determined based on the mean distance between the first device and the second device and the first distance between the first device and the second device.

[0070] For example, suppose there are four devices A, B, C, and D. If the first device is A, then the second devices are B, C, and D. The mean distances between the first and second devices are Rab, Rac, and Rad; the first distances between the first and second devices are Dab, Dac, and Dad. Then the corresponding first variance and data for the first device are:

[0071] Ea=(Rab-Dab)2+(Rac-Dac)2+(Rad-Dad)2;

[0072] Similarly, when the first device is B, C, or D, the corresponding first variance and data for the first device are as follows:

[0073] Eb=(Rab-Dab)2+(Rbc–Dbc)2+(Rbd-Dbd)2;

[0074] Ec=(Rac-Dac)2+(Rbc-Dbc)2+(Rcd-Dcd)2;

[0075] Ed=(Rad-Dad)2+(Rbd-Dbd)2+(Rcd-Dcd)2.

[0076] Accordingly, determining the second variance and data corresponding to the first device based on the new ranging information of each of the devices, the calibration position information of the first device, and the known position information of the second device includes: determining the second distance between the first device and the second device based on the calibration position information of the first device and the known position information of the second device; and determining the second variance and data corresponding to the first device based on the mean ranging between the first device and the second device and the second distance between the first device and the second device.

[0077] Here, the second distance refers to the adjusted distance between the first device and the second device. In this embodiment, the second distance between the first device and the second device can be determined based on the calibration position information of the first device and the known position information of the second device; furthermore, the corresponding second variance and data of the first device are determined based on the mean distance measurement between the first device and the second device and the second distance between the first device and the second device.

[0078] For example, suppose there are four devices A, B, C, and D. If the first device is A, then the second devices are B, C, and D. The second distances between the first and second devices are Dab', Dac', and Dad'. Then the corresponding second variance and data for the first device are:

[0079] Ea=(Rab–Dab’)2+(Rac–Dac’)2+(Rad–Dad’)2;

[0080] Similarly, when the first device is B, C, or D, the corresponding second variance and data for the first device are as follows:

[0081] Db=(Rab–Dab’)2+(Rbc–Dbc’)2+(Rbd–Dbd’)2;

[0082] Dc=(Rac–Dac’)2+(Rbc–Dbc’)2+(Rcd–Dcd’)2;

[0083] Dd=(Rad-Dad')2+(Rbd-Dbd')2+(Rcd-Dcd')2.

[0084] Based on the above embodiments, optionally, the step of mapping the location information of the plurality of devices that meet the calibration conditions onto the electronic map includes: performing coordinate transformation on the location information of the plurality of devices that meet the calibration conditions in the map coordinate system to obtain the location information of each device in the target map coordinate system, and mapping the location information of each device in the target map coordinate system onto the electronic map.

[0085] The coordinate transformation includes, but is not limited to, operations such as flipping, translation, and rotation. In this embodiment, the position information of each device in the map coordinate system can be transformed to obtain the position information of each device in the target map coordinate system; wherein, the target map coordinate system refers to a map coordinate system that conforms to the actual electronic map orientation. Furthermore, the position information of each device in the target map coordinate system is mapped onto the electronic map to obtain the coordinate points of the devices on the electronic map, thereby marking the deployment locations of the devices.

[0086] The technical solution of this embodiment involves acquiring the distance information of each device after deployment, where the distance information is the distance between the device and other devices. A map coordinate system is constructed based on any distance information, and the initial position information of each device in the map coordinate system is determined based on the distance information of each device. During the calibration of the initial position information of each device, for the first device, the calibration position information of the first device is determined based on the known position information of the second device. New distance information is acquired for each device, and the calibration position information and initial position information of the first device are judged based on the new distance information until the position information of multiple devices meets the calibration conditions. The position information of the multiple devices that meet the calibration conditions is then mapped onto an electronic map. Here, the first device is any one of the multiple devices, and the second device is any other device besides the first device. The known position information of the second device is either its initial position information or its calibration position information. This allows for precise marking of the deployed device positions on the electronic map, avoiding inaccurate positioning due to incorrect marking, improving the accuracy of device deployment position marking, and thus improving positioning accuracy.

[0092] The location information calibration module 240 is used to continue acquiring new ranging information for each of the devices, and to determine the calibration location information and the initial location information of the first device based on the new ranging information, until the location information of multiple devices meets the calibration conditions, and to map the location information of the multiple devices that meet the calibration conditions onto an electronic map; wherein, the first device is any one of the multiple devices, and the second device is any other device besides the first device; the known location information of the second device is the initial location information or calibration location information of the second device.

[0093] The technical solution of this embodiment involves acquiring the distance information of each device after deployment, where the distance information is the distance between the device and other devices. A map coordinate system is constructed based on any distance information, and the initial position information of each device in the map coordinate system is determined based on the distance information of each device.

Here, the first device is any one of the multiple devices, and the second device is any other device besides the first device.
