Description

Technical Field

[0001] The present application belongs to the technical field of human factors engineering and ergonomics, and in particular, relates to a data processing method, device and system, edge data processing equipment and medium. Background Art

[0002] With the rapid development of modern technology, portable GPS (Global Positioning System) devices have become one of the indispensable tools in people's daily lives. Such devices can provide users with accurate location information and navigation services by receiving satellite signals in the Earth's orbit.

[0003] Existing portable GPS devices mainly rely on a single GPS signal source. However, in environments such as urban areas with tall buildings, dense forests or underground parking lots, GPS signals are easily blocked and reflected by buildings, trees or other obstacles, resulting in increased positioning errors. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a data processing method, device and system, edge data processing equipment and medium to improve the accuracy of positioning.

[0005] In a first aspect, the present application provides a data processing method, comprising:

[0006] When the received satellite data meets a preset condition, storing the satellite data as positioning data in a storage module;

[0007] When the received satellite data does not meet the preset conditions, receiving the device posture detection data sent by the inertial measurement unit; storing the device posture detection data as positioning data in the storage module;

[0008] The control communication module sends the positioning data to the host computer.

[0009] According to the data processing method of the present application, when the received satellite data meets the preset conditions, the satellite data is stored in the storage module as positioning data; when the received satellite data does not meet the preset conditions, the device posture detection data sent by the inertial measurement unit is received; the device posture detection data is stored in the storage module as positioning data, and the communication module is controlled to send the positioning data to the host computer. The embodiment of the present application realizes high-accuracy positioning in a variable environment through innovative integrated technology. When satellite data that meets the preset conditions is received, it is used as positioning data to improve high-precision positioning in open areas. In an environment where satellite data is limited, it automatically switches to the inertial measurement unit, and uses the device posture detection data of the inertial measurement unit for auxiliary positioning, and sends these positioning data to the host computer through the communication module, so that the host computer can generate location information based on the received data and visualize it on the pre-stored map, combining the advantages of satellite positioning and inertial navigation, effectively alleviating the limitations of a single positioning method, and improving the accuracy of positioning.

[0010] According to an embodiment of the present application, the preset condition includes: the signal strength of the satellite data is greater than a preset value;

[0011] Before determining whether the satellite data meets a preset condition, the satellite data is corrected by using a real-time dynamic differential positioning technology.

[0012] In this embodiment, by correcting the original satellite data using real-time dynamic differential positioning technology before determining whether the satellite data meets the preset conditions, the error in satellite signal propagation can be reduced, significantly improving the accuracy of positioning data. By introducing signal strength as a preset condition, the screening mechanism when receiving satellite data is enhanced, thereby ensuring that only high-quality signals are used for positioning calculations. When the signal strength exceeds the preset threshold, indicating that the signal is strong and stable enough, these data will be received by the controller and stored as valid positioning data, reducing the positioning error caused by using satellite data with weak or unstable signals.

[0013] According to an embodiment of the present application, the control communication module sends the positioning data to the host computer, including:

[0014] In the real-time transmission mode, controlling the communication module to send the received satellite data and / or the device posture detection data sent by the inertial measurement unit as positioning data to the host computer; and / or,

[0015] In a non-real-time transmission mode, the communication module is controlled to send the positioning data in the storage module to a host computer.

[0016] In this embodiment, in real-time transmission mode, the communication module is controlled to send the satellite data sent by the positioning module and / or the sensor data sent by the inertial measurement unit as positioning data to the host computer, and store these data in the storage module, thereby reducing the loss of some data caused by poor wireless signal quality.

[0017] In this embodiment, by storing the satellite data sent by the positioning module and / or the sensor data sent by the inertial measurement unit as positioning data in the storage module in a non-real-time transmission mode, it can be applied to some scenarios that require long-term data recording, so that the positioning data in the storage module can be subsequently sent to the host computer through the communication module.

[0018] According to one embodiment of the present application, the method further includes:

[0019] When the first event mark button is triggered, the first triggering time when the first event mark button is triggered is marked in the positioning data.

[0020] In this embodiment, an event mark button is introduced. When the event mark button is triggered, the first trigger time of this specific event will be recorded in the positioning data, giving the device the ability to time-mark specific events, allowing the system to provide users with accurate time reference points to facilitate subsequent analysis and processing.

[0024] The communication module is controlled to send the positioning data, the human physiological data, the event marking data, and the time information to a host computer.

[0025] In this embodiment, by collecting human physiological data, synchronous monitoring and analysis of the user's physiological state and position information are achieved, and a second event marking button is provided to record the second trigger time when the button is triggered. The first trigger time and the second trigger time can be used to accurately align the positioning data with the human physiological data in the time dimension, thereby realizing the fusion analysis of multi-source data, allowing users to intuitively understand the changes in physiological indicators under specific events or environments, and improving the accuracy of data processing and analysis.

[0026] According to one embodiment of the present application, the method further includes:

[0028] In the non-real-time transmission mode, the communication module is controlled to send at least part of the data stored in the storage module to the host computer.

[0029] In this embodiment, by storing the positioning data, the human physiological data, the event marking data, and the time information in the storage module, when the network connection is unstable or the amount of data is large, the data can be stored first and then transmitted when network conditions permit, thereby improving the integrity and reliability of the data.

[0065] The data processing method, apparatus and system, edge data processing equipment and medium provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0066] The data processing method may be applied to a terminal, and may be specifically executed by hardware or software in the terminal.

[0067] The terminal includes, but is not limited to, a portable communication device such as a mobile phone or tablet computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad). It should also be understood that in some embodiments, the terminal may not be a portable communication device, but a desktop computer with a touch-sensitive surface (e.g., a touch screen display and / or a touch pad).

[0068] In the following various embodiments, a terminal including a display and a touch-sensitive surface is described. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, a mouse and a joystick.

[0069] The data processing method provided in the embodiment of the present application may be executed by an edge data processing device or a functional module or functional entity in the edge data processing device that can implement the data processing method. The edge data processing device mentioned in the embodiment of the present application includes but is not limited to mobile phones, tablet computers, computers, cameras, and wearable devices. The data processing method provided in the embodiment of the present application is described below using the edge data processing device as an example of the execution subject.

[0070] like Figure 1 As shown, the data processing method includes: step 110, step 120 and step 130.

[0071] Step 110: When the received satellite data meets a preset condition, the satellite data is stored in a storage module as positioning data;

[0072] Step 120: When the received satellite data does not meet the preset conditions, receiving the device posture detection data sent by the inertial measurement unit; and storing the device posture detection data as positioning data in the storage module;

[0073] Step 130: Control the communication module to send the positioning data to the host computer.

[0074] In an embodiment of the present application, a positioning module may receive satellite data. The positioning module may be a global navigation satellite system receiver for receiving satellite data. For example, the positioning module may be one of a GPS receiver, a Beidou navigation system receiver, a GLONASS receiver, a Galileo receiver, etc., or may be integrated with multiple receivers described above. The satellite data may include the distance between the positioning module and the satellite, the relative speed between the positioning module and the satellite, the satellite identifier, the time when the satellite sends data, the navigation message of the satellite, etc. Satellite data sent from multiple satellites are received, and positioning is achieved through triangulation or trilateral measurement.

[0075] An inertial measurement unit (IMU) is a device that integrates multiple sensors to measure and report specific forces, angular velocity, and acceleration of an object. IMU can provide real-time data about the state of motion of an object. In environments where satellite data may be temporarily lost or signal quality is poor, such as indoors or in urban canyons, IMU can provide continuous measurement data to help quickly acquire or restore positioning. For example, when satellite data is lost, the IMU can use its accelerometer and gyroscope to measure the acceleration and angular velocity changes of the object. By integrating these measurements, the IMU can calculate the distance and direction the object has moved from the last known position. The position when the satellite data is lost can be used as the initial position, and then dead reckoning can be used to estimate the current position. Among them, the device posture detection data is the measurement data provided by the IMU, or the position data, attitude data, etc. estimated based on the measurement data provided by the IMU.

[0076] The storage module can be used to temporarily or long-term store the collected and processed data, including satellite data, IMU device posture detection data, etc. The storage module can be a flash memory (Flash Memory), a random access memory module (Random Access Memory, RAM), a hard disk drive (Hard Disk Drive, HDD), a solid state drive (Solid State Drive, SSD), an SD card (Secure Digital Card), etc. Those skilled in the art can use different storage modules according to actual conditions, and the embodiments of the present application are not limited to this.

[0077] The communication module is a component for the edge data processing device to transmit data with external devices or apparatuses, and the communication module may include at least one of a wireless communication module and a wired communication module. For example, the communication module may include wireless communication modules such as a Wi-Fi module, a Bluetooth module, and a cellular module (such as a 2G / 3G / 4G / 5G module); and may include wired communication modules such as an Ethernet module, a USB module, a serial communication module (such as RS-232, RS-485), an HDMI, and a DisplayPort module. Taking the communication module as a USB module and the storage module as an SD card as an example, the storage module may also include a card reader chip, and the host computer may be connected to the edge data processing device through the USB module, and the edge data processing device may control the card reader chip to perform data access operations on the SD card, thereby realizing direct reading of SD card data without plugging and unplugging the SD card.

[0078] In this embodiment, by integrating wireless and wired communication modules in the communication module, flexible and reliable data transmission capabilities are provided, and the most appropriate communication method can be selected according to specific application scenarios and environmental conditions, so that positioning data can be stably and reliably transmitted from the edge data processing device to the host computer.

[0079] In this embodiment, the host computer can be responsible for collecting positioning data from the edge data processing device, processing and analyzing the positioning, and possibly visualizing the results. The host computer can be an electronic device or a functional module or functional entity in an electronic device, and the electronic device includes but is not limited to a mobile phone, a tablet computer, a computer, a server, and a wearable device.

[0080] In this embodiment, the host computer may store map data for generating location information according to the positioning data and displaying the location information in the pre-stored map data.

[0081] Specifically, the host computer can be connected to the edge data processing device by wireless or wired means to receive the positioning data sent by the edge data processing device. The host computer can parse the positioning data, calculate the location of the edge data processing device, including longitude, latitude, altitude and other information, and then load the pre-stored map data, which can be digital maps, satellite images or other Geographic Information System (GIS) data, map the calculated location to the map data, determine the exact location of the edge data processing device on the map, and display the location information on the map on the user interface of the host computer, for example, the mark, trajectory line or other visual indication of the edge data processing device can be displayed.

[0082] It should be noted that, in this embodiment, the host computer displays the location information on the map on the user interface through the positioning data, which is one of the applications of the host computer for the positioning data. In the field of human factors engineering, ergonomics technology or other related fields, edge data processing equipment or other equipment can collect data related to the human body, machine, and / or environment, and the edge data processing equipment and / or the host computer can synchronize these data, and then perform comprehensive analysis and display in the host computer. For example, in this embodiment, after the positioning data is collected, various physiological signals, biomechanical signals, human visual signals, human interaction information, etc. of when, where, and who can be recorded, and the association between people, time, and space can be established, thereby performing relevant behavioral analysis such as user experience.

[0083] In some embodiments, before determining whether the satellite data meets the preset conditions, the satellite data can be corrected by real-time kinematic differential positioning technology (RTK). Among them, RTK technology is a method of correcting satellite data errors using differential signals to improve positioning accuracy. Its basic principle is: an RTK base station is set at a fixed point at a known position, which receives satellite data and calculates the error of its position; the base station sends these errors as differential data to the positioning module; the positioning module receives satellite data from the satellite and differential data from the base station, and uses the differential data to correct the satellite data.

[0084] In this embodiment, by correcting the original satellite data using real-time dynamic differential positioning technology before determining whether the satellite data meets the preset conditions, the error in satellite signal propagation can be reduced, and the accuracy of the positioning data can be significantly improved.

[0085] In some embodiments, the preset condition may be that the signal strength of the satellite data is greater than a preset value, that is, if the signal strength of the satellite data is greater than the preset value, it is determined that the preset condition is met.

[0086] Of course, the preset condition may also be other conditions. For example, the quality of satellite data may be evaluated by using the signal-to-noise ratio (SNR) of the satellite data. When the signal-to-noise ratio of the satellite data is greater than a preset value, the preset condition is determined. Alternatively, the C / N0 (Carrier-to-Noise Ratio) value of the satellite data may be calculated. The higher the C / N0 value, the better the signal quality. When the C / N0 value is greater than a preset value, the preset condition is determined. Those skilled in the art may set the preset condition according to actual conditions, and the embodiments of the present application are not limited thereto.

[0087] In the embodiment of the present application, if the satellite data meets the preset conditions, it means that the condition of the satellite data is good, the satellite data can be used for positioning, and the satellite data can be stored in the storage module as positioning data. When the satellite data does not meet the preset conditions, it means that the condition of the satellite data is poor, for example, the signal strength of the satellite data is poor, the quality is poor, or the satellite data is lost. In this case, it is difficult to obtain accurate positioning information from the satellite data. Therefore, it can be switched to the inertial navigation mode to obtain the device posture detection data sent by the inertial measurement unit, and the device posture detection data is stored in the storage module as positioning data, so as to maintain the continuity and reliability of positioning.

[0088] In some embodiments, the received satellite data may be converted and compressed as necessary to reduce redundancy during data transmission and improve transmission efficiency. For example, the received satellite data may be converted into a hexadecimal format of a private protocol, and only necessary key information (such as latitude and longitude, altitude, timestamp, etc.) may be extracted and stored, and redundant data (such as repeated status information) may be removed to achieve efficient data management and transmission.

[0089] According to the data processing method of the present application, when the received satellite data meets the preset conditions, the satellite data is stored in the storage module as positioning data; when the received satellite data does not meet the preset conditions, the device posture detection data sent by the inertial measurement unit is received; the device posture detection data is stored in the storage module as positioning data, and the communication module is controlled to send the positioning data to the host computer. The embodiment of the present application realizes high-accuracy positioning in a variable environment through innovative integrated technology. When satellite data that meets the preset conditions is received, it is stored as positioning data, which improves high-precision positioning in open areas. In an environment where satellite data is limited, it automatically switches to the inertial measurement unit, and uses the device posture detection data of the inertial measurement unit for auxiliary positioning, and sends these positioning data to the host computer through the communication module, so that the host computer can generate location information based on the received data and visualize it on the pre-stored map, combining the advantages of satellite positioning and inertial navigation, effectively alleviating the limitations of a single positioning method, and improving the accuracy of positioning.

[0090] In some embodiments, controlling the communication module to send the positioning data to the host computer includes:

[0091] In the real-time transmission mode, the control communication module sends the received satellite data and / or the device posture detection data sent by the inertial measurement unit as positioning data to the host computer.

[0092] In some embodiments, controlling the communication module to send the positioning data to the host computer includes:

[0093] In the non-real-time transmission mode, the control communication module sends the positioning data in the storage module to the host computer.

[0094] In this embodiment, the edge data processing device may include a real-time transmission mode and a non-real-time transmission mode. Whether the edge data processing device is in real-time transmission mode or non-real-time transmission mode can be identified in any way. For example, the edge data processing device may be provided with a mode control button. When the button is in a pressed state, it can be determined that the edge data processing device is in real-time transmission mode, and when the button is in a released state, it can be determined that the edge data processing device is in non-real-time transmission mode; or when the button is in a pressed state, it corresponds to a non-real-time transmission mode, and when the button is in a released state, it corresponds to a non-real-time transmission mode; it can also be determined that the edge data processing device is in real-time transmission mode when the edge data processing device establishes a wireless connection with the host computer, and when the edge data processing device establishes a wired connection with the host computer, it is determined that the edge data processing device is in non-real-time transmission mode. The embodiment of the present application does not limit how to identify whether the edge data processing device is in real-time transmission mode or non-real-time transmission mode.

[0095] In the real-time transmission mode, the data transmission process has real-time requirements, and the edge data processing device will transmit the collected data to the host computer in real time. That is to say, in the real-time transmission model, the edge data processing device will collect data while transmitting the collected data to the host computer in real time. In the non-real-time transmission mode, after collecting data, the edge data processing device will store the collected data in the storage module and transmit it to the host computer when necessary. For example, in some scenarios, the edge data processing device is disconnected from the network connection with the host computer. When necessary, it can be when the network connection is restored, or when the edge data processing device loses data or has data errors during the real-time data transmission process, and needs to obtain data from the storage module. Different modes can be applicable to different application scenarios. For example, in scenarios that require long-term data recording, such as field mapping, environmental monitoring, etc., non-real-time transmission mode can be used, and in scenarios with high real-time requirements, such as driving a vehicle, walking navigation, etc., real-time transmission mode can be used.

[0096] An example is used to illustrate the data processing process when the edge data processing device is in different modes. Figure 2 As shown, in this example, the positioning module in the edge data processing device is a GPS module, the controller is a single-chip microcomputer, the storage module is an SD card and a card reader chip, the wireless communication module is a Bluetooth module, and the wired communication module is a USB module.

[0097] like Figure 2As shown, in the real-time transmission mode, the microcontroller can send the satellite data sent by the GPS module and / or the device posture detection data sent by the inertial measurement unit to the host computer via Bluetooth, and store the satellite data sent by the GPS module and / or the device posture detection data sent by the inertial measurement unit in the SD card to reduce the data loss caused by poor Bluetooth signal. In the case of non-real-time transmission mode, the offline data in the SD card can be sent to the host computer through the USB interface through the card reader chip.

[0098] In this embodiment, in real-time transmission mode, the communication module is controlled to send the satellite data sent by the positioning module and / or the sensor data sent by the inertial measurement unit as positioning data to the host computer, and store these data in the storage module, thereby reducing the loss of some data caused by poor wireless signal quality.

[0099] In this embodiment, by storing the satellite data sent by the positioning module and / or the sensor data sent by the inertial measurement unit as positioning data in the storage module in a non-real-time transmission mode, it can be applied to some scenarios that require long-term data recording, so that the positioning data in the storage module can be subsequently sent to the host computer through the communication module.

[0100] In some embodiments, the method further comprises:

[0101] When the first event mark button is triggered, the first triggering time when the first event mark button is triggered is marked in the positioning data.

[0102] In this embodiment, the first event marking button may be a physical button on the edge data processing device, and the user may mark the event by pressing this button. The state of the first event marking button may be monitored, and when the user presses the first event marking button, the current timestamp may be captured, and this timestamp is the first trigger time. Then, the captured first trigger time may be associated with the current positioning data, for example, the timestamp may be added to a specific field of the positioning data set to form a tag marked with the timestamp.

[0103] In this embodiment, an event mark button is introduced. When the event mark button is triggered, the first trigger time of this specific event will be recorded in the positioning data, giving the device the ability to time-mark specific events, allowing the system to provide users with accurate time reference points to facilitate subsequent analysis and processing.

[0104] In some embodiments, the method further comprises:

[0105] Collecting human physiological data, and when the second event mark button is triggered, marking a second triggering time when the second event mark button is triggered in the human physiological data;

[0106] Aligning the positioning data and the human physiological data in the time dimension according to the first trigger time and the second trigger time, or sending the human physiological data marked with the second trigger time to the host computer so that the host computer can align the positioning data and the human physiological data in the time dimension according to the first trigger time and the second trigger time;

[0107] The control communication module sends the positioning data, human physiological data, event marker data, and time information to the host computer.

[0108] In this embodiment, the edge data processing device may also be integrated with any medical or health monitoring instrument that can measure and record human physiological data. For example, the edge data processing device may be integrated with a heart rate monitor, a blood pressure monitor, a smart watch or a health tracking bracelet, or a functional module that integrates multiple human physiological data monitoring functions, such as heart rate, blood pressure estimation, blood oxygen saturation, etc.

[0109] In this embodiment, the second event marking button can be a physical button on the edge data processing device, and the user can mark the event by pressing this button. The state of the second event marking button can be monitored. When the user presses the second event marking button, the current timestamp can be captured, and this timestamp is the second trigger time. Then, the captured first trigger time is associated with the current human physiological data. For example, the timestamp can be added to a specific field of the human physiological data set to form a tag marked with a timestamp.

[0110] In some embodiments, the positioning data and human physiological data can be aligned in the time dimension according to the first trigger time and the second trigger time. Specifically, since the edge data processing device may use different sensors or functional modules to collect positioning data and human physiological data, these sensors or functional modules may have clocks that are not synchronized, so that the timestamps of different types of data have deviations. In this case, the deviation between the timestamps of the positioning data and the human physiological data can be calculated according to the first trigger time and the second trigger time. For example, if the first trigger time and the second trigger time are the same, the acquisition time of the positioning data at the time of the first event mark key triggering and the acquisition time of the human physiological data at the time of the second time mark key triggering can be obtained, and the deviation between the timestamps of the positioning data and the human physiological data can be determined according to the difference between the timestamps corresponding to the positioning data and the timestamps corresponding to the human physiological data. If the timestamp of the positioning data is faster than the timestamp of the human physiological data, the timestamp of the positioning data can be subtracted from the deviation, or the timestamp of the human physiological data can be added to the deviation to achieve alignment of the positioning data and the physiological data in the time dimension. Of course, if the first trigger time and the second trigger time are not the same, the difference between the first trigger time and the second trigger time needs to be considered in the process of calculating the deviation between the timestamps of the positioning data and the human physiological data.

[0111] In some embodiments, the process of aligning the positioning data and the human physiological data in the time dimension can also be performed in the host computer. For example, after receiving the positioning data and the human physiological data sent by the edge data processing device, the host computer can align the positioning data and the human physiological data in the time dimension according to the first trigger time and the second trigger time.

[0112] In this embodiment, the event marking data may be an event triggered by the first event key mark and / or the second event key mark, and the time information may be the first trigger time and / or the second trigger time. In this embodiment, the positioning data, human physiological data, event marking data, and time information may be sent to the host computer so that the host computer can synchronize these data and then conduct comprehensive analysis, display, etc. For example, positioning data, human physiological data, event marking data, and time information can be used to analyze various physiological signals, biomechanical signals, human visual signals, human interaction information, etc. of when, where, and who, and establish the association between people, time, and space, thereby conducting relevant behavior analysis such as user experience.

[0113] In this embodiment, by collecting human physiological data, synchronous monitoring and analysis of the user's physiological state and position information are achieved, and a second event marking button is provided to record the second trigger time when the button is triggered. The first trigger time and the second trigger time can be used to accurately align the positioning data with the human physiological data in the time dimension, thereby realizing the fusion analysis of multi-source data, allowing users to intuitively understand the changes in physiological indicators under specific events or environments, and improving the accuracy of data processing and analysis.

[0114] In some embodiments, the method further comprises:

[0115] storing the positioning data, human physiological data, event marker data, and time information in a storage module;

[0116] In the non-real-time transmission mode, the communication module is controlled to send at least part of the data stored in the storage module to the host computer.

[0117] In this embodiment, when the network quality is poor or in other circumstances, it is inconvenient to transmit the collected data in real time. The positioning data, human physiological data, event marking data, and time information can be stored in a storage module, so that in a non-real-time transmission mode, at least part of the data stored in the storage module can be sent to the host computer.

[0118] In this embodiment, by storing positioning data, human physiological data, event marking data, and time information in a storage module, when the network connection is unstable or the amount of data is large, the data can be stored first and then transmitted when network conditions permit, thereby improving the integrity and reliability of the data. In addition, in the non-real-time transmission mode, the batch transmission of data reduces the occupancy of communication resources and reduces communication costs.

[0119] The data processing method provided in the embodiment of the present application can be executed by a data processing device. In the embodiment of the present application, the data processing device provided in the embodiment of the present application is described by taking the data processing method executed by the data processing device as an example.

When satellite data that meets the preset conditions is received, it is stored as positioning data, which improves high-precision positioning in open areas. In an environment where satellite data is limited, it automatically switches to the inertial measurement unit, and uses the device posture detection data of the inertial measurement unit for auxiliary positioning, and sends these positioning data to the host computer through the communication module, so that the host computer can generate location information based on the received data and visualize it on the pre-stored map, combining the advantages of satellite positioning and inertial navigation, effectively alleviating the limitations of a single positioning method, and improving the accuracy of positioning.

[0130] In this embodiment, by storing the satellite data sent by the positioning module and / or the sensor data sent by the inertial measurement unit as positioning data in the storage module in a non-real-time transmission mode, it can be applied to some scenarios that require long-term data recording, so that the positioning data in the storage module can be subsequently sent to the host computer through the communication module.
