[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please see Figure 1 As shown, this invention discloses a method for positioning a lamp, which mainly includes the following steps:

[0039] Acquire motion data of the device during its movement;

[0040] Monitor the communication signal strength of the lights in the current scene;

[0041] The location information of the target luminaire is determined and marked based on the communication signal strength and motion data measured at different locations;

[0042] A location map of the marked lamps is generated and displayed.

[0043] Thus, the lamp positioning method of the present invention can not only accurately mark the location information of the lamps, but also automatically generate a lamp location map, which facilitates the subsequent control, maintenance and management of the lamps.

[0044] Combination Figure 2 and Figure 3 As shown, specifically, the target luminaire is a luminaire positioned parallel to the equipment, and preferably the luminaire corresponding to the location where the equipment moves to be below it. The motion data is the data of the equipment moving to be below the target luminaire within the space where the luminaire is located, including acceleration and angular velocity information, which is measured by the inertial measurement unit inside the equipment.

[0045] The device specifically uses a mobile phone as an example. Before monitoring the communication signal strength of lights in the current scene, the lighting location method of this invention requires activating the communication function module of the device (i.e., the mobile phone) to put the phone in a communication state. Then, the mobile phone is used to detect the communication signal strength of nearby lights in real time. Simultaneously, the mobile phone will display the currently detected communication signal strength of the lights and an estimated possible location of the lights in real time, helping the user determine whether the mobile phone is under the target light.

[0046] It is important to emphasize that the lamp positioning method of this invention locates each lamp individually. That is, by monitoring the communication signal strength of the lamps, determining whether the signal strength is within a certain threshold, and then obtaining the device's position through motion data, the position of the lamps located above the device is determined. The user needs to move to the area under each lamp; after moving past all lamps, the positioning of all lamps is completed by default.

[0047] The aforementioned steps of determining and marking the location information of the target luminaire based on communication signal strength and motion data measured at different locations mainly include: obtaining the device's position and motion trajectory at the corresponding time based on motion data collected at multiple times and the location information of the reference luminaire, thus obtaining a rough location information of the target luminaire; when the communication signal strength is detected to be higher than a preset threshold, obtaining the communication signal strength at the corresponding location; and determining the target luminaire's location information in the current scene based on the communication signal strength and motion trajectory detected by the device at different locations, thus obtaining the target luminaire's precise location information.

[0048] Optionally, the present invention can determine the precise location information of the target lamp through trilateration algorithm and fingerprint positioning algorithm, and can ensure that the error of the location mark is within an acceptable range, preferably less than 1 meter in an indoor environment.

[0049] Specifically, the preferred communication signal strength is the Bluetooth signal strength, and the trilateration algorithm can be implemented in the following three ways:

[0050] 1. Select three lamps with strong signal strength and relatively dispersed locations as reference points. The coordinates of the reference points are the true values ​​obtained from third-party measurements.

[0051] 2. Estimate the coordinates of the mobile phone at its current location based on the distance obtained from the signal strength conversion, and then use a trilateration algorithm to determine the position of the lamp.

[0052] The specific method is as follows: Assume that the coordinates of the three lamps are (x1, y1), (x2, y2), and (x3, y3), and the distances from the mobile phone to the three lamps at the current position are d1, d2, and d3, respectively.

[0053] Knowing the Bluetooth signal strength of three lights in space can be used to estimate the distance from a mobile phone to these three lights. It is necessary to establish a model relating Bluetooth signal strength to distance, for example, using a logarithmic distance path loss model. Where d represents the distance from the mobile phone to the light fixture, RSSI0 is the signal strength at the reference distance, RSSI is the actual measured signal strength, and n is the path loss exponent, which is usually determined experimentally.

[0054] The Bluetooth signal strengths of the three lamps were substituted into the Bluetooth signal strength versus distance relationship model to calculate the estimated distances from the mobile phone to the three lamps, which were denoted as d1, d2, and d3 respectively.

[0055] Based on geometric relationships, the position of the mobile phone satisfies the following system of equations:

[0056]

[0057] By solving this system of equations, we can obtain the coordinates of the phone at its current location. Combined with the Bluetooth signal strength of the light fixture above the phone at its current location, we can determine the location of the target light fixture.

[0058] The above describes the calculation method for two-dimensional space.

[0059] Similarly, in three-dimensional space, given the phone's position as (x, y, z), the distance from the phone to the reference light fixture as d, and the reference light fixture's position coordinates as (X, Y, Z), then we have: (Xx) 2 +(Yy) 2 +(Zz) 2 =d 2 By constructing a system of equations and solving this system of equations, the position coordinates of the target lamp can be determined.

[0060] 3. To improve the accuracy of location estimation, iterative optimization methods can also be used. As the mobile phone collects more data from different locations, the distance parameters in the trilateration algorithm and the mobile phone's location information are continuously updated, allowing the lamp's location estimation to gradually converge to a more accurate value. Simultaneously, other optimization algorithms, such as least squares and Newton's iteration method, can be combined to further improve the accuracy of location estimation.

[0061] It is understandable that: based on motion data collected at multiple times, corresponding motion trajectories can be obtained. Thus, during the user's movement, the positional relationship between adjacent points can be determined through the motion trajectory. Then, the position of the first target light fixture, determined by the true value, can be combined with the positional relationship of adjacent points to determine the position of the second target light fixture, and so on.

[0062] The fingerprint positioning algorithm is used to calculate the location information of the target light fixture, which specifically includes the following steps:

[0063] During the offline training phase, RSSI signal values ​​of each lamp at multiple different locations within the space where the lamps are located are collected to establish a fingerprint database that corresponds one-to-one between location information and RSSI signal values.

[0064] The specific steps of the offline training phase are as follows:

[0065] Multiple reference points are selected along the movement trajectory of the device to form a grid-like distribution, and the position coordinates of each reference point are recorded.

[0066] At each reference point, the RSSI signal values ​​from each lamp are measured to form a corresponding signal feature vector. The RSSI signal values ​​from each lamp can be measured multiple times and averaged to improve accuracy.

[0067] The position coordinates and signal feature vectors of all reference points are stored to establish a fingerprint database.

[0068] During the online positioning phase, the RSSI signal value of the target luminaire is detected and matched with the data in the fingerprint database. The RSSI signal value that is closest to the RSSI signal value of the target luminaire in the fingerprint database is found, and the location information corresponding to the closest RSSI signal value is used as the location information of the target luminaire.

[0069] The specific steps in the online positioning phase are as follows:

[0070] When the device moves within the space where the lamps are located, it detects the RSSI signal values ​​received by the device from each lamp at the current position and forms a real-time signal feature vector.

[0071] The similarity between the real-time signal feature vector and the signal feature vector of each reference point in the fingerprint database can be calculated using methods such as Euclidean distance and cosine similarity, without any restrictions.

[0072] Select the K reference points with the highest similarity. Based on the coordinates of these K reference points, calculate the device's current location coordinates. Use similarity as a weight to calculate a weighted average of the K reference point coordinates to obtain the device's current location coordinates. Through fingerprint positioning algorithms, the location of a mobile phone in an indoor space can be determined relatively accurately, thereby pinpointing the precise location of the target lighting fixture.

[0073] The present invention provides a method for generating and displaying a lamp location map based on the marked location information of lamps. Specifically, this includes: mapping the three-dimensional coordinates representing the location information of the target lamps onto a two-dimensional plane corresponding to the current scene using a map drawing library to obtain the location information of the target lamps; combining the product information and / or status information of the target lamps with the location information to generate a lamp location map displaying all lamps in the current scene. The lamp location map can be displayed on the device's screen. Users can zoom, pan, and view detailed information of the location map on the device, and can also choose to share or save the location map.

[0074] like Figure 4 As shown, this invention also discloses a lighting fixture positioning system capable of implementing the aforementioned lighting fixture positioning method. The lighting fixture positioning system includes a control module 100, an IMU data acquisition module 200, a communication signal detection module 300, a location marking module 400, a communication function module 500, a data upload module 600, and a location map generation module 700. It can not only accurately mark the location information of lighting fixtures and precisely add them, but also automatically generate lighting fixture location maps, providing an efficient and accurate solution for lighting fixture management.

[0075] The control module 100 is used for data interaction and command transmission, and is responsible for the operation control of the entire system. In this embodiment, the device is preferably a mobile phone, and the control module 100 is a mobile application. The control module 100 has an operating interface, which includes function icons for starting / stopping data acquisition, displaying the current status, and prompting operation. The current status display includes the number of detected lamps and the communication signal strength of each lamp. The control module 100 provides the user with a clear operating interface and rich function options. When the control module 100 on the device is started, the control module 100 automatically checks whether the IMU data acquisition module 200 and the communication signal detection module 300 are turned on and available. If they are not available, the user will be prompted to configure them.

[0076] The IMU data acquisition module 200 is used to acquire motion data of the device during its movement. Connected to the control module 100, the IMU data acquisition module 200 collects motion data of the device as it moves within the space where the lamp is located and moves to the area below the target lamp, and transmits this data to the control module 100. Specifically, the IMU data acquisition module 200 is an inertial measurement unit inside the device. It uses the device's built-in accelerometer, gyroscope, and magnetometer to acquire motion data, including acceleration information, angular velocity information, direction data, and magnetic field strength. The IMU data acquisition module 200 samples at a high frequency to obtain accurate motion data; its sampling frequency is 50Hz-200Hz, and the acquired motion data is represented in a three-dimensional coordinate format, such as acceleration [x,y,z], angular velocity [x,y,z], and magnetic field strength [x,y,z].

[0077] The communication signal detection module 300 is connected to the control module 100 and is used to monitor the communication signal strength of the lights in the current scene, that is, the communication signal strength emitted by each light in the space where the light is located. The communication signal strength is related to the distance between the light and the device. The communication signal detection module 300 can obtain multiple RSSI signal values ​​and transmit them to the control module 100. The communication signal detection module 300 is preferably a Bluetooth signal detection module, which can use the device's BLE function to scan and monitor the Bluetooth signal strength of each light. The Bluetooth signal strength changes with the distance between the device and the light. Of course, in other optional embodiments, other communication methods can also be used, and there is no limitation on this.

[0078] When monitoring the communication signal strength emitted by each lamp, the communication signal detection module 300 filters out target lamps with communication signal strength higher than a preset threshold, obtains the RSSI signal value of the target lamp, and transmits RSSI signal values ​​higher than the preset threshold to the control module 100. Optionally, the preset threshold is preferably -60dBm. When the RSSI signal value is higher than the preset threshold, it indicates that the device is close to the lamp, which not only improves the accuracy of the lamp position information but also reduces the amount of data transmitted, making transmission faster and reducing the amount of data processed by the control module 100.

[0079] The position marking module 400 is used to determine and mark the position information of the target luminaire based on the communication signal strength and motion data measured at different positions. Specifically, the position marking module 400 is connected to the control module 100 and is used to calculate and mark the position information of the target luminaire based on the motion data collected by the IMU data acquisition module 200 and the RSSI signal value detected by the communication signal detection module 300. The target luminaire is the luminaire corresponding to the device when it moves beneath it.

[0080] Specifically, the position marking module 400 infers the device's position and movement trajectory at corresponding moments based on motion data collected at multiple times as the device moves to the area beneath the target light fixture within the space where the light fixture is located, and the position information of a reference light fixture, thereby obtaining a rough position information of the target light fixture. In this embodiment, the movement trajectory is the path the device takes to move to the area beneath the target light fixture. However, there may be obstacles beneath the light fixture preventing the device from moving to the area beneath the target light fixture, or there may be positional deviations, causing the target light fixture's position to be either on or near the device's movement trajectory. That is, the position information of the target light fixture obtained through the device's movement trajectory is only a rough position information of the target light fixture.

[0081] The location marking module 400 also calculates the precise location information of the target lamp in the current scene based on the communication signal strength and motion trajectory detected at the aforementioned multiple times (i.e., the device at different locations), using a trilateration algorithm and a fingerprint positioning algorithm, and marks the precise location information.

[0082] The location marking module 400, in conjunction with the IMU data acquisition module 200 and the communication signal detection module 300, performs positioning and identification of the lamps, achieving accurate acquisition and marking of lamp location information and improving the accuracy of lamp positioning. In this embodiment, the lamp location information is represented in the form of an indoor coordinate system, such as custom coordinates based on room dimensions and reference points. Of course, in other optional embodiments, the location information can also be represented in the form of latitude and longitude, and there is no limitation on this.

[0083] The communication module 500 establishes a communication connection with the Bluetooth module of the target luminaire via a communication protocol. Each luminaire has a Bluetooth module that continuously broadcasts data packets containing product information and communication signal strength. Upon receiving the data packets, the device can parse the RSSI signal value, which ranges from -100dBm to 0dBm, reflecting the distance between the device and the luminaire. The luminaire's product information includes a unique identifier, type, and model. The device displays the currently detected luminaire signal strength and the estimated possible location of the luminaire in real time, helping the user determine if they are under the target luminaire.

[0084] Before monitoring the communication signal strength of the lights in the current scene, the communication signal detection module 300 needs to activate the device's communication function module 500 to put the device in a communication state. This allows the device to detect the communication signal strength of the target lights in real time during movement, which is then monitored by the communication signal detection module 300. The communication function module 500 can also acquire product information of the target lights and transmit this information, along with the communication signal strength data acquired at different locations, to the control module 100, which in turn transmits it to the location marking module 400. Preferably, after determining and identifying the target lights, the communication function module 500 can also encapsulate the product and location information of the target lights into a specific data format and transmit it to the control module 100.

[0085] The data upload module 600 is used to upload product information and the communication signal strength of the target luminaire at the corresponding real-time location to the server when the detected communication signal strength is higher than a preset threshold. Specifically, the data upload module 600 is connected to the control module 100. The control module 100 obtains the packaged product information and location information of the target luminaire and uploads this information to the server via protocols such as HTTP or MQTT. The server adds the information to the database and assigns a unique management ID for subsequent analysis and management. The upload progress and status are displayed during the upload process. If the upload fails, it will automatically retry or prompt the user to check the network connection. After successful addition, the control module 100 displays a success message and updates the list of added luminaires.

[0086] Optionally, in this embodiment, the server is a remote device management system server used for remote monitoring and management of the lighting fixtures. After obtaining the location information of the lighting fixtures, the system can accurately identify the target lighting fixture when adding it, and quickly and accurately add the lighting fixture to the device management system.

[0087] The point location map generation module 700 is used to generate and display a point location map of the marked lamps based on their location information. Specifically, the point location map generation module 700 is connected to the control module 100 and the server, respectively. It obtains the product information and location information of the marked target lamps from the server, and maps the three-dimensional coordinates representing the location information of the target lamps onto the two-dimensional plane corresponding to the current scene using a map drawing library to obtain the point location information of the target lamps. At the same time, it also adds the product information and / or status information of the target lamps to the point location information of the target lamps to generate a point location map displaying all lamps in the current scene.

[0088] Optionally, after obtaining the corresponding parameters of each lamp, different lamp statuses can be represented by different icons or colors, such as normal status and fault status, forming an intuitive lamp location map, which is then displayed on the device's screen. Users can zoom, pan, and view detailed information of the location map on the device, and can also choose to share or save the location map, i.e., output it as an image file and store it on the device.

[0089] The location map generation module 700 can clearly display the distribution of lighting fixtures in space. The generated location map helps equipment managers quickly understand the layout of the lighting fixtures, formulate reasonable maintenance plans and emergency solutions, and facilitate equipment management.

[0090] Furthermore, the lamp positioning system of this invention provides a verifiable method for lamp positioning. By strategically arranging multiple similar lamps in a pre-defined experimental environment, the method of this invention is applied to mark and add lamp positions, and generate a location map. Subsequently, the accuracy of the generated lamp position information, the precision of equipment addition, the correctness of the location map, and the accuracy and timeliness of uploading lamp identification and location information are verified through on-site visual comparison. This invention can be widely applied to large commercial spaces, office areas, industrial plants, schools, hospitals, homes, and other locations with multiple similar lamps, facilitating the addition, identification, and positioning of lamps. In addition, the generated lamp location map helps equipment managers quickly understand the lamp layout and develop reasonable maintenance plans and emergency response schemes. The uploaded lamp identification and location information can be used for remote monitoring and management.

[0091] In summary, this invention acquires motion data of the device during its movement and monitors the communication signal strength of the lights in the current scene. Based on the communication signal strength and motion data measured at different locations, it determines and marks the position information of the target lights. Then, a light fixture location map can be generated and displayed based on the marked light fixture position information. Compared to existing technologies, this invention not only accurately marks the position information of lights and precisely adds lights, but also automatically generates a light fixture location map, facilitating subsequent control, maintenance, and management of the lights.

[0092] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
