Description

Technical Field

[0001] The patent of this invention relates to the field of high-precision positioning technology, specifically, to a full-process information system for drone data collection and processing. Background Art

[0002] RTK (Real-time kinematic) carrier phase differential technology is a differential method for real-time processing of carrier phase observations of two measuring stations. The carrier phase collected by the base station is sent to the user receiver to calculate the coordinates. This is a new and commonly used satellite positioning measurement method. The previous static, fast static, and dynamic measurements all required post-calculation to obtain centimeter-level accuracy. RTK is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It uses a carrier phase dynamic real-time differential method and is a major milestone in GNSS applications. Its appearance has brought new measurement principles and methods to engineering layout, topographic mapping, and various control measurements, greatly improving work efficiency.

[0003] The working principle of RTK is to observe and receive satellite data through the base station, and send the observation data to the mobile station in real time through the radio station (data link). When the mobile station receives the data from the base station, it also observes and receives satellite data. At the same time, the mobile station performs real-time differential operations based on the base station data and its own data according to the principle of relative positioning, thereby solving the three-dimensional coordinates of the mobile station and its accuracy. Its positioning accuracy can reach the range of 1cm to 2cm. The use of RTK technology can make it possible for observation stations to have no line of sight (no need to be within the line of sight), with high positioning accuracy, simple operation, and all-weather operation. It is a mature and commonly used positioning technology; in addition, network RTK technology establishes multiple GNSS reference stations in a region to form a mesh coverage, and calculates and publishes GNSS correction information based on one or more of these base stations, thereby performing real-time correction positioning for GNSS users in the region, which can further improve the positioning accuracy and efficiency.

[0004] PPK (Post-Processing Kinematic) differential technology is a positioning technology corresponding to RTK. It is a dynamic relative positioning technology that uses carrier phase observations for post-processing. Since it is post-processing, users do not need to be equipped with a data communication link, and naturally do not need to consider whether the mobile station can receive the radio signal broadcast by the base station. The observation is more convenient and free, and is suitable for areas where real-time positioning results are not required.

[0005] The working principle of PPK is to use a base station receiver and at least one mobile receiver for synchronous observation to observe the carrier phase of the satellite; afterwards, the GNSS processing software is used in the computer to perform linear combination to form a virtual carrier phase observation value to determine the centimeter-level relative position between the receivers; then the coordinate conversion is performed to obtain the coordinates of the mobile station in the local coordinate system. Compared with RTK technology, when the differential signal cannot be received due to more or less environmental factors, PPK technology is used for measurement. PPK technology does not require data communication, and the operating radius can reach more than 300 kilometers. GNSS can also be used for dynamic measurement in areas where RTK is restricted. It can be said to be an important supplementary operation method for RTK.

[0006] At present, with the development of network RTK technology and post-PPK technology, the applications that follow are also diverse; however, the software using these technologies has more or less some thresholds, and the existing network RTK technology or post-PPK technology applications are basically used separately, and most of them are still limited to desktop software. There is no mature information system that includes mission planning and collection, real-time network RTK application combined with post-PPK application full process automation.

[0007] Therefore, the present invention aims to provide a full-process information system for drone data collection and processing to solve the above-mentioned problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] Reference Figure 1-2 The figure shows a preferred embodiment of the present invention.

[0037] A full-process information system for drone data collection and processing, including a cloud management and control platform, PPK underlying services, communication base stations and collection terminals.

[0038] The cloud management and control platform includes RTK acquisition service module, PPK solution service module, task management module and data management module.

[0039] The RTK acquisition service module includes a CORS account management unit, an acquisition order unit, and an acquisition data management unit; the CORS account management unit allows users to enter third-party CORS accounts purchased from third-party CORS service providers such as Qianxun, Beidou, and Huace for RTK acquisition, and at the same time uniformly manage the third-party CORS accounts entered by users; the acquisition order unit is used to create separate CORS acquisition orders for users and manage orders after the real-time RTK function is enabled. Specifically, it manages the acquisition orders created during task execution after real-time network RTK is checked when creating a task, and also includes the creation of separate RTK acquisition tasks.

[0040] The CORS data collection and forwarding in the data collection management unit is to receive the longitude and latitude data that need to be collected through MQTT, and then splice them into complete GGA data, and then submit the GGA data to the third-party CORS service through the NTRIP protocol to obtain GNSS positioning data, and then send the obtained GNSS positioning data to the communication base station through MQTT. At the same time, the data is stored in the local cache as a dat file, and the file is uploaded to OSS when the task is completed. The specific MQTT communication process includes client, server, topic and message; the client is an Internet device used to connect to the MQTT server, and the server is responsible for receiving connections and messages from the client, and processing the publishing and subscription of messages. The topic is a hierarchical naming method, similar to the URL path. When the client sends a message to the server or receives a message from the server, a topic will be specified. The message is the data sent by the client to the server or received from the server. The specific message in this embodiment is longitude data, latitude data and other location related information. Through the data collection management unit, the longitude data and latitude data messages that need to be collected are received using MQTT communication. The information is then spliced ​​into complete GGA data, and the MQTT communication methods include three communication methods: publish and subscribe, request and response, and direct communication between clients; the communication process of publish and subscribe is that the client can publish messages to a topic and subscribe to one or more topics to receive messages, the communication process of request and response is that the client can send a request to a specific topic, and other clients can respond to this request, and the communication process of direct communication between clients supports point-to-point communication; in actual applications, the data collection management unit can choose the communication method with the highest communication efficiency to receive the longitude data, latitude data and other location-related information that need to be collected.

[0041] When submitting GGA data to a third-party CORS service through the NTRIP protocol to obtain GNSS positioning data, the NTRIP protocol submission process is to first establish a TCP connection between the client and the ntrip server, then the client will send an NtripCaster query request message to request an available data stream, and the Ntrip server will return a list of available data streams to the client by sending an NtripCaster response message. The client selects a data stream from the list of available data streams and sends an NtripCaster selection request message to the Ntrip server. Immediately afterwards, the Ntrip server returns the relevant information of the selected data stream to the client by sending an NtripCaster response message. The client sends an NtripCaster data stream connection request message to the Ntrip server, and the Ntrip server returns a data stream connection confirmation to the client by sending an NtripCaster response message. At this time, the client starts to send RTCM (Real-Time Control The client sends a differential data request message to the Ntrip server, and the Ntrip server returns the corresponding RTCM differential data to the client by sending an RTCM differential data response message. Finally, the client decodes and applies the RTCM differential data to accurately obtain real-time GNSS positioning results and complete the task of submitting the complete GGA data to the third-party CORS service to obtain GNSS positioning data.

[0042] The PPK solution service module includes a PPK configuration unit and a PPK management unit; the PPK configuration unit specifically performs solution configuration according to the user's specific business and actual needs. In this embodiment, a variety of commonly used PPK solution configurations can be set as PPK solution default configurations to improve the user's convenience and practicality; the PPK management unit also specifically includes PPK solution order management and PPK solution processing, wherein the PPK solution order management is to create a post-PPK solution order based on the generated dat file and the user's PPK solution configuration after the task execution with the post-PPK solution function checked is completed; wherein the PPK solution processing is to communicate with the PPK underlying service according to the general HTTP communication protocol defined by the PPK underlying service, and after submitting a request to start the PPK solution task, the solution task status is obtained at preset time intervals, and the status of the solution order is updated based on the obtained task status, and when the calculation task is completed, the order status is updated and SMS, email or in-site letter is synchronously triggered to notify the user, and then the user can download the corresponding solution data for other applications.

[0043] In this embodiment, the PPK management unit also specifically includes a task list management subunit and a task data download subunit; the task list management subunit is used to manage the PPK task list created after the task is completed with real-time network RTK and post-PPK checked; the task data download subunit is used to download the post-PPK solution data.

[0044] The task management module includes a task creation unit, a task planning unit and a task execution unit; the task creation unit is used to manage the selection of the real-time network RTK function and the post-PPK solution function, as well as the filling of basic task information; the task planning unit is used to plan the acquisition task; the task execution unit is used to execute the planned tasks; specifically, the user selects the communication base station equipment, the operating drone model and the load type, draws the target by importing the target KML file or by stamping the map, and selects the real-time network RTK function and the post-PPK function. When the real-time network RTK function is selected, the task management module will call the RTK acquisition service to verify whether the current user has a CORS account. Only when the current account has CORS resources can the real-time network RTK function be selected, and then the task route is generated, and then the task is saved to complete the task creation.

[0045] In this embodiment, the process of using the RTK acquisition service to verify the CORS account of the test user specifically includes: using the RTK device to connect to the user's CORS account, entering the correct IP address, port number, source node, user name and password information, and checking whether a fixed solution has been obtained in the handbook or software of the RTK device to ensure that the RTK device can successfully connect to the user's CORS network and receive the differential signal, and then select the known control points in the survey area for point verification, place the mobile station of the RTK device on the control point, collect the coordinate value, and calculate the error by comparing the collected coordinate value with the known coordinate value. Through multiple measurements and comparisons, verify whether the measurement accuracy of the user's CORS account meets the project requirements. Different control points can be used for verification to evaluate the stability and reliability of the CORS account. Finally, the data of each measurement, including coordinate values, errors and other information, are recorded, and the data is analyzed to evaluate the performance and applicability of the CORS account.

[0046] In this embodiment, the task creation unit also includes an RTK function management subunit, a PPK function management subunit and a task information subunit; the RTK function management subunit is used to check the real-time network RTK function, and the user needs to have a CORS account in the RTK acquisition service to check it; the PPK function management subunit is used to check the post-PPK solution function, and the real-time network RTK function needs to be checked before it can be checked; the task information subunit is used to fill in the basic information of the task.

[0047] After the task is created and planned, the environment for executing the task is prepared. When the environment is prepared, the task is executed. The specific execution process of the task is as follows: at the beginning of the task, the RTK acquisition service on the cloud control platform receives the posture information reported by the communication base station based on MQTT communication, automatically selects one of the idle CORS accounts under the user account, and establishes communication with the third-party platform of the corresponding CORS account based on the Ntrip protocol. Then, the longitude and latitude in the posture information are spliced ​​into complete GGA data, and then the GGA data is submitted to the third-party CORS platform to receive real-time GNSS positioning data, and sent to the communication base station based on MQTT communication. Then the communication base station converts the received JSON data into binary data, and then transmits the GNSS positioning data to the airborne end through the traditional data transmission link for real-time differential processing. At the same time, the RTK acquisition service of the cloud control platform will write the received GNSS positioning data into the dat file of the current task so that the PPK solution task can be created after the task is completed, making the collection and processing of task data more automated.

[0048] After the task is completed, the task management module first notifies the RTK acquisition service to upload the dat data file of the current task to OSS and obtains the uploaded OSS file address. Then the task management module notifies the PPK solution service module to create a PPK solution task. The task's own operation data can also be managed and viewed in the data management module. After the PPK solution task is created, the PPK solution service will request the PPK underlying service to obtain the solution status every 10 seconds. When the current solution task is completed, the user will be notified through the cloud management platform's internal letter, SMS or email, and the user can download the settled data for related applications.

[0049] In this embodiment, the RTK acquisition service uploads the dat data file of the current task to OSS with multiple upload methods, including simple upload, multi-part upload, additional upload, breakpoint resume upload and form upload; the simple upload method is suitable for uploading small dat data files, the size of the entire dat data file does not exceed 5GB, the operation is simple, and the entire dat data file is uploaded at one time by calling the PutObject interface provided by OSS without special configuration; the multi-part upload method is suitable for uploading large dat data files, the size of the entire dat data file does not exceed 48.8TB, and the entire dat data file is divided into multiple pieces and uploaded in parallel by calling multiple interfaces provided by OSS, including InitiateMultipartUpload, UploadPart, and CompleteMultipartUpload, and then merged and finally uploaded the entire dat data file after the upload is completed. When the upload is interrupted due to unstable network environment, the client can manually record which segments failed to be uploaded so as to facilitate retransmission; the append upload method is suitable for uploading dat data files that need to continuously add data, including some video stream dat data obtained, with a file size not exceeding 5GB. The dat data file is uploaded by calling the AppendObject interface provided by OSS and an Appendable type Object is generated. The Appendable type Object allows direct appending of content, and each additional uploaded data can be read immediately. Non-Appendable type Objects do not support appended uploads; the breakpoint resume upload method is suitable for uploading large dat data files in an unstable network environment. The size of the dat data file does not exceed 48.8TB. By calling the OSSSDK based on the segmented upload encapsulation method, such as the specific Java The SDK's uploadFile function can automatically record the upload progress on the client side, and then continue uploading from the last stop point after an interruption. The form upload method is suitable for users to upload objects in HTML web pages. The size of the dat data file does not exceed 5GB. The dat data file is uploaded to OSS by initiating an HTTP POST request. At the same time, the PostPolicy generated by the server can also be used to limit the dat data files uploaded by the client, which can specifically include limiting the file size and file type, so that the dat data files can be limited to OSS.

[0050] The data management module is used to manage various data after the task operation, including RTK acquisition data and PPK solution data. The PPK underlying service is connected to the cloud management and control platform, and the GNSS positioning data obtained from the third-party CORS service provider by calling the cloud management and control platform is processed to generate result data. This enables this solution to link various applications through the cloud management and control platform and combine the existing network RTK technology and post-PPK technology applications to form a set of information systems that include full-process automation of task planning and acquisition, real-time network RTK application and post-PPK application, which reduces the current threshold for applying RTK technology and post-PPK technology.

[0051] The communication base station is connected to the cloud control platform for communication, and the received data is formatted. In this embodiment, the communication base station specifically includes a large ground base station, a micro 4G communication module site and a micro 5G communication module site. The micro 4G communication module site and the micro 5G communication module site can be placed on the acquisition terminal to follow the drone for real-time data transmission. At the same time, the communication module adopts advanced communication protocols and technologies, has good anti-interference ability and stability, can operate stably for a long time in harsh mission environments, and ensure the continuity and stability of flight missions.
