Description

Technical Field

[0001] The present invention relates to a relative position positioning system and a relative position positioning method thereof, and in particular to a relative position positioning system and a relative position positioning method thereof that can quickly find a position. Background Art

[0002] Traditional positioning methods often use triangulation to calculate the position of an object on a map. To determine the distance between two objects, existing technologies require finding three known positioning points for each object. After obtaining these six positions, the coordinates of the two objects (i.e., their x and y values) are calculated to further determine the distance between them. Therefore, existing methods are cumbersome and time-consuming. If one of the objects is moving, the slow calculation process makes it impossible to instantly detect its position.

[0003] Therefore, it is necessary to invent a new relative position positioning system and relative position positioning method thereof to solve the deficiencies of the prior art. Summary of the Invention

[0004] The main purpose of the present invention is to provide a relative position positioning system that can quickly find the position.

[0005] Another main object of the present invention is to provide a relative position positioning method for the above system.

[0006] To achieve the above-mentioned purpose, the relative position positioning system of the present invention is used in a space, and the space may also have a device to be tested. The relative position positioning system includes multiple receivers and a main device. The multiple receivers are all located in the space, wherein each receiver includes a first signal transmission module and a data integration module. The first signal transmission module is used to transmit a positioning signal. The data integration module is electrically connected to the first signal transmission module. The main device includes a second signal transmission module and a calculation module. The second signal transmission module is used to return a first reply signal after receiving the positioning signal; wherein the data integration module generates first positioning data based on the first reply signal. The calculation module is electrically connected to the second signal transmission module. When the first receivers receive the first reply signal, the first signal transmission modules of the first receivers transmit the first positioning data to the second signal transmission module, so that the calculation module can find the multiple distances between the first receivers and the device under test. When the device under test is located in the space, the device under test transmits the second reply signal after receiving the multiple positioning signals. The first signal transmission module of the second receiver that receives the second reply signal then transmits the second positioning data to the second signal transmission module, where the second receiver is one of the first receivers. The calculation module then calculates the relative position relationship between the host device and the device under test based on the second positioning data.

[0007] The relative position positioning method of the present invention is used in a relative position positioning system to find the relative position relationship between a main device and a device to be tested in a space. The space also includes multiple receivers. The method includes the following steps: controlling multiple receivers to broadcast multiple positioning signals; causing the main device to return a first reply signal after receiving multiple positioning signals; controlling multiple first receivers to transmit first positioning data to the main device, causing the main device to find multiple distances between the multiple first receivers; wherein the multiple first receivers receive the first reply signal; causing the device to be tested to return a second reply signal after receiving multiple positioning signals; controlling the second receiver to transmit second positioning data to the main device; wherein the second receiver belongs to the multiple first receivers and receives the second reply signal; and then calculating the relative position relationship between the main device and the device to be tested based on the second positioning data.

[0027] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0028] Please refer to Figure 1 System architecture diagram of the relative position positioning system of the present invention.

[0029] In one embodiment of the present invention, a relative position positioning system 1 is used in a space A. Space A can be an indoor or outdoor venue, but the present invention is not limited to this. The relative position positioning system 1 includes multiple receivers 10 and a main device 20. The main device 20 uses multiple receivers 10 to obtain the relative position of the device under test 30 entering the space A. The receivers 10, the main device 20 and the device under test 30 can all transmit wireless signals, such as signals that comply with the Bluetooth Mesh or low-power Bluetooth beacon standards, but the present invention is not limited to this signal type. Multiple receivers 10 are all located in the space A, and the position coordinates of the multiple receivers 10 are all known. The receiver 10 can be any computer system, base station, home appliance, furniture, etc., and the present invention is not limited to its type. Each receiver 10 includes a first signal transmission module 11 and a data integration module 12. The first signal transmission module 11 is used to continuously broadcast positioning signals to the outside. The positioning signal can be transmitted to the host device 20 or the device under test 30, and the first signal transmission module 11 can also receive the return signal from the host device 20 or the device under test 30. The data integration module 12 is electrically connected to the first signal transmission module 11 to integrate the signals received by the first signal transmission module 11.

[0030] The host device 20 can be a smartphone or a smart wearable device, but the present invention is not limited thereto. The host device 20 includes a second signal transmission module 21 and a calculation module 22. After receiving multiple positioning signals, the second signal transmission module 21 transmits a first response signal to the receiver 10. The data integration module 12 of the receiver 10 then generates first positioning data based on the first response signal. The positioning signal and the first response signal can be an identification code, a power level, or a wireless received signal strength (RSSI) of the receiver 10 and the host device 20, respectively. Therefore, the first positioning data generated by the data integration module 12 can include the identification code, power level, or wireless received signal strength of both. The first signal transmission module 11 then transmits the first positioning data back to the host device 20. The receiver 10 can adjust the power level to adjust the accuracy. Increasing the decibel level of the power level results in a stronger signal strength, which can make the calculation result more accurate. The calculation module 22 is electrically connected to the second signal transmission module 21. Based on the first positioning data transmitted by the receiver 10, the calculation module 22 can determine the distance to the receiver 10. Upon receiving multiple pieces of first positioning data, the calculation module 22 can calculate the distances between the host device 20 and each of the multiple receivers. Thus, once the distances to the three receivers are known, the calculation module 22 can use the principle of triangulation to calculate the coordinates of the host device 20 on a map. Since the principle of triangulation is well known to those skilled in the art, its principles will not be elaborated upon here.

[0031] The device under test 30 can also be a smart phone or a smart wearable device, and can be placed on a pet, child or other moving object. It also has a third signal transmission module 31 that can transmit signals. When the device under test 30 enters the space A, the third signal transmission module 31 of the device under test 30 also transmits a second reply signal to the receiver 10 after receiving the multiple positioning signals. At this time, the data integration module 12 of the receiver 10 that receives the second reply signal generates a second positioning data based on the second reply signal. The second positioning data can also include the identification code, power level or wireless receiving signal strength of the receiver 10 and the device under test 30. The first signal transmission module 11 then transmits the second positioning data to the second signal transmission module 21 of the main device 20, so that the calculation module 22 can find the relative position relationship between the main device 20 and the device under test 30.

[0032] It should be noted that the calculation module 22 can use the first and second positioning data to determine the two straight-line distances from the host device 20 and the device under test 30 to the receiver 10, and then use the receiver 10, which is located in the same direction as the device under test 30, to determine the approximate angle. Using these two straight lines and the angle, the distance and angle from the host device 20 to the device under test 30 can be determined, thereby determining the relative positions of the two devices.

[0033] It should be noted that the modules of the receiver 10, the main device 20 and the device under test 30 can be constructed in the form of hardware devices, software programs combined with hardware devices, firmware combined with hardware devices, etc. For example, a computer program product can be stored in a computer-readable medium and read and executed to achieve the various functions of the present invention, but the present invention is not limited to the above-mentioned methods. In addition, this embodiment only illustrates the preferred embodiment of the present invention. In order to avoid redundancy, not all possible variations and combinations are described in detail. However, it should be understood by those skilled in the art that not all of the above modules or components are necessary. In order to implement the present invention, other more detailed existing modules or components may also be included. Each module or component may be omitted or modified as needed, and there may not be other modules or components between any two modules.

[0034] For details on how to find the relative position of the device under test 30, please refer to Figure 2 The relative position positioning method of the present invention is a flowchart of the steps and Figure 3 Schematic diagram of the relative positions of the master device, the device under test, or multiple receivers of the present invention. It should be noted that although the relative positioning system 1 described above is used as an example to illustrate the relative positioning method of the present invention, the relative positioning method of the present invention is not limited to the relative positioning system 1 with the same structure as described above.

[0035] It should be noted that the multiple receivers 10 are categorized below according to their respective uses as first receivers 101, second receivers 102, and third receivers 103. The multiple first receivers 101 are devices that transmit first positioning data to the host device 20 for distance calculation by the calculation module 22. The second receiver 102 is a device that transmits second positioning data to the host device 20 for distance calculation by the calculation module 22, and the second receiver 102 must be one of the multiple first receivers 101. The third receiver 103 is a device that the calculation module 22 uses to perform angle calculations.

[0036] by Figure 3 Taking the figure shown as an example, the relative position positioning system 1 may include 9 receivers 10a to 10i, but the present invention is not limited to this number, and the arrangement of the receivers 10a to 10i is not limited to 9. Figure 3 Therefore, step 201 is first performed: controlling the plurality of receivers to transmit a plurality of positioning signals.

[0037] First, receivers 10a to 10i will broadcast positioning signals at any time.

[0038] Then, step 202 is performed: after receiving the plurality of positioning signals, the master device transmits back a first response signal.

[0039] At this point, the second signal transmission module 21 of the host device 20 may receive the multiple positioning signals and return a first response signal. Therefore, the second signal transmission module 21 of the host device 20 may receive positioning signals from the closer receivers 10a, 10b, and 10d and then return the first response signal to the receivers 10a, 10b, and 10d.

[0040] Then, step 203 is performed: controlling the plurality of first receivers to integrate and transmit a first positioning data to the host device, so that the host device can find out a plurality of distances between the plurality of first receivers.

[0041] The data integration modules 12 of the multiple first receivers 101 (i.e., receivers 10a, 10b, and 10d) that receive the first reply signal then integrate the data into first positioning data. The first signal transmission module 11 then transmits the first positioning data to the host device 20. The calculation module 22 of the host device 20 can then use the principle of triangulation to calculate the distances D1, D2, and D3 between the host device 20 and the receivers 10a, 10b, and 10d, thereby further determining the coordinates of the host device 20.

[0042] Then proceed to step 204: after receiving the plurality of positioning signals, the device under test transmits back a second response signal.

[0043] When the device under test 30 enters the space A, the third signal transmission module 31 of the device under test 30 may also receive at least one positioning signal from the receivers 10a to 10i. Therefore, the third signal transmission module 31 of the device under test 30 will return a second reply signal.

[0044] Then proceed to step 205: control a second receiver to integrate and transmit a second positioning data to the host device.

[0045] Depending on the distance, not every receiver 10a through 10i will receive the second reply signal. However, the data integration module 12 of the second receiver 102 that receives the second reply signal integrates the second reply signal and the positioning signal of the second receiver 102 to generate second positioning data, which is then transmitted to the host device 20 via the first signal transmission module 11. The second receiver 102 must also be a device within the plurality of first receivers 101. Therefore, in this embodiment, the second receiver 102 is receiver 10d.

[0046] Finally, step 206 is performed: calculating the relative position relationship between the master device and the device under test.

[0047] Finally, the calculation module 22 of the main device 20 calculates the distance D4 between the device under test 30 and the receiver 10d based on the second positioning data. Furthermore, using the second receiver 102 as a reference, the calculation module 22 uses the third receiver 103, which is located in the same direction as the device under test 30, to determine the angle θ. In other words, from the perspective of receiver 10d, receiver 10i and the device under test 30 are located in the same direction. Therefore, in this embodiment, the third receiver 103 is receiver 10i. The calculation module 22 of the main device 20 calculates the angle θ based on the position, distance, and slope of receiver 10d and receiver 10i. Since the slopes between receiver 10d and receiver 10i are similar to those between receiver 10d and the device under test 30, the approximate length and slope of the distance D5 between the main device 20 and the device under test 30 can be calculated based on the angle θ and the distances D3 and D4. This allows the relative position of the main device 20 and the device under test 30 to be determined.

[0048] It should be noted that the relative position positioning method of the present invention is not limited to the above-mentioned order of steps. As long as the purpose of the present invention can be achieved, the above-mentioned order of steps can also be changed.

[0049] By using the relative position positioning method and relative position positioning system 1 of the present invention, the approximate position of the device under test 30 can be quickly found in a specific space A without being restricted by the Wi-Fi network, without the need to tediously calculate the precise coordinates of the device under test 30 .

[0050] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
