Description

Method and device for batch management and automatic processing of satellite navigation real-time data stream

Technical Field

The present invention relates to the field of Beidou positioning technology, and in particular to a method and device for batch management and automatic processing of satellite navigation real-time data streams.

Background technique

Beidou ground-based augmentation stations can observe Beidou satellites in real time and generate data streams in RTCM (Radio Technical Commission for Maritime Services) format, which are transmitted to the data distribution center through the dedicated network via the NTRIP (Networked Transport of RTCM via Internet Protocol) protocol, and broadcast to users in real time through the Internet. Using the real-time data stream of Beidou ground-based augmentation stations, real-time and post-positioning high-precision positioning can be performed, but post-positioning requires saving the RTCM data of the station and converting it into the corresponding RINEX (Receiver Independent Exchange Format) observation file before it can be recognized and processed in post-processing software such as GAMIT and BERNESE. Therefore, a ground-based augmentation station RTCM data stream batch management and format conversion system is designed to realize data storage and conversion of multiple Beidou ground-based augmentation stations, which is convenient for post-positioning. At present, the RTCM data stream of the station can be stored and managed in three ways: based on GNSS (Global Navigation Satellite System) receivers, based on receiver supporting software, and based on third-party software. For existing GNSS receivers, the receivers store raw data and convert it to RINEX format. However, this method can only save the observation information of the current site and needs to be configured in advance, making it difficult to achieve batch management. The random software that comes with the GNSS receiver can also store and convert data streams, but the degree of automation is low and it is mostly based on the Windows platform, making it difficult to deploy to a Linux server for automatic, batch management and security control. Existing third-party software including RTKLIB, IGGNtrip, etc. can achieve batch storage and conversion of data, but it is usually in the form of a console, which is difficult to display in real time, and the management mode is relatively simple, making it difficult to manage and maintain data from a single or multiple stations.

Summary of the invention

In order to overcome the problems existing in the prior art and to address the low degree of automation in site batch management and data conversion, the purpose of the present invention is to provide a method and device for batch management and automatic processing of satellite navigation real-time data streams.

Detailed ways

In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

The present invention is described in detail below with reference to the accompanying drawings and embodiments.

A first aspect of the present invention provides a method for batch management and automatic processing of satellite navigation real-time data streams, comprising the following steps:

Step 1: Generate user control information.

Specifically, it includes adding the NTRIP access IP, port, account and password of the site data stream, RTCM and RINEX file storage and push path, data stream interruption information log storage path, and RTCM to RINEX data conversion parameter configuration.

Step 2: RTCM data access verification and storage.

Specifically, it includes real-time data stream access of RTCM, data stream information verification and RTCM original data stream storage.

Step 3: Execute scheduled tasks.

Specifically, monitor the user-defined conversion time and read the RTCM task list.

Step 4: Convert the RTCM data stream into RINEX data stream.

According to the user parameter configuration and RTCM data stream file, the data stream is converted to the RINEX data stream.

Step 5: Merge duplicate files from multiple time periods.

Specifically, it automatically identifies observation files of multiple time periods in a single day at a station and automatically merges them.

Step 6: Data file online service.

Specifically, the user uploads the converted RINEX file to the cloud processor and generates relevant log and alarm information.

In one embodiment of the present invention, it is assumed that there are three reference station data streams accessed in real time, and the station names are A001, A002, and A003 respectively. The specific implementation is as follows:

Step 1: Generate user control information. User control information is mainly configured by the program configuration file, including the configuration of A001, A002, A003 data stream access information, SFTP storage path and push configuration, system operation log configuration, and data automatic conversion configuration.

In the configuration of data stream access information, you can add site access address lists in batches by adding them line by line to generate data stream access control information. The format of the site access address list is as follows:

ROVER＝<NAME>,NtripClient,<IP>,<PORT>,<NAME>,<USER>,<PASSWD>；

Among them: NAME is the site name, IP is the site data connection address, PORT is the connection port, USER is the NTRIP account, and PASSWD is the connection password.

The SFTP storage path and push configuration mainly configures the remote push directory of SFTP. You can set the file directory structure according to year and accumulated days for automatic classification, storage and push. The configuration method is to directly add "SFTP=<PATH>" in the configuration file, where PATH is the remote push directory of SFTP.

The system operation log configuration is mainly used to configure the interruption information of the data flow. The configuration method can be directly added to the configuration file "LOG = <PATH>", where PATH is the log storage directory.

The data conversion configuration mainly configures the type of data conversion and the timer start time. The configuration method can be directly modified or a new configuration file is added to correspond to "RTCM2RNX=<VER>" and "CONV_T=<TIME>" for setting, where VER is the conversion version, which can be 2.1X or 3.0X, and TIME is the time of the timer conversion in the format of hhmmss (hours, minutes, seconds).

Step 2: RTCM data access verification and storage. Use the RTCM data stream access module to access and store the original observation data in RTCM format of the site locally, and add the station name and timestamp to the file name to facilitate subsequent conversion configuration. The example format of the saved file name is: <NAME>_<YYYYMMDD>_<hhmmss>.rtcm3, where NAME is the site name, YYYYMMDD is the year, month and day information, and hhmmss is the hour, minute and second information. For example, the data file name of the A001 site at 0:0:01 on January 1, 2022 is "A001_20220101_000001.rtcm3". During the data access process, the status of the data stream is monitored by the following methods:

When the program is running, the INT type parameter (0: abnormal connection, 1: normal connection) of the TCP communication status of each site in the site access list is determined by looping, and written into the one-dimensional array BREAK[2]={INT _t-1 , INT _t } of the site, where t-1 and t represent the TCP status of the previous second and the current moment respectively. The rules for determining the data flow interruption information according to the BREAK data status are as follows:

BREAK[2]＝{1,0}: The connection status changes from normal to abnormal, and the interruption time is recorded;

BREAK[2]＝{0,0}: the connection status remains abnormal and the interruption duration increases by 1 second;

BREAK[2]＝{0,1}: The connection status changes from abnormal to normal, and the recovery time is recorded once;

The above rules can be used to monitor the status and interruption of data flow and save it as log file information to facilitate data integrity verification.

Step 3, execute the scheduled task. After the program is running, the global running timer matches the current time with the user-defined conversion time once a second. After the current time matches the user-configured time, the RTCM data folder file list in the control information is read and a file name list that complies with the RINEX specification is generated. At the same time, a RINEX standard file is generated in the RINEX conversion file path.

Step 4: Convert the RTCM data stream into a RINEX data stream.

The RTCM to RINEX module is used to convert the RINEX format one by one. The conversion process includes two steps: RTCM data parsing and RINEX file writing. The RTCM parsing process parses the binary data of the observation message according to the RTCM protocol standard to obtain the pseudorange, phase, Doppler value and other observation information of each signal frequency point, and writes the parsed observation information into the format conversion file corresponding to the station according to the RINEX format standard.

Step 5: Merge duplicate files of multiple time periods. To meet the needs of converting RTCM data of multiple days or multiple time periods to RINEX files, it is necessary to monitor the duplication of file names when writing files after RINEX conversion, and create multi-time period file markers ending with "(2)", "(3)", etc. After conversion, check the time period files one by one. If they contain multi-time period markers, merge the other time period files based on the first file. The merging rules are as follows:

Take the first RINEX file as the benchmark file, read the RINEX files with the multi-period file suffix in sequence, delete the file header of the multi-period file, keep only the data information, and then append the data information to the end of the benchmark file. It should be noted that when reading the "TIME OF LAST OBS" information in the file header of the last period file, it is necessary to record the end time of the observation period and replace the end time of the observation period in the file header of the benchmark file.

Step 6: Data file online service. The stored RTCM data and converted RINEX files are stored in the data server. After the user passes the account and password verification, he can access the file database to obtain the required file list. The server returns the download address to the user. If the file requested by the user does not exist or the data flow is abnormal, a service warning message is generated and fed back to the user.

The present invention also relates to a device for batch management and automatic processing of satellite navigation real-time data, which includes a control module, a data stream access module, a data conversion module, a safe and lightweight service module, a display module, and a control module, providing a human-computer interaction interface for users, facilitating users to perform site data access information, SFTP file and interruption log file storage path, RTCM to RINEX file conversion configuration, and the configured information will be packaged and sent to the data stream access module; the data stream access module mainly implements data access, parsing and storage processes through a processor and a memory according to the data access and file storage path and conversion information of the control module, and sends the RTCM storage path and conversion parameters to the data conversion module; the data conversion module parses RTCM data through a processor according to the RTCM storage path and conversion information, and converts the RTCM data to a RINEX file according to the conversion parameters; the safe and lightweight service module mainly provides RTCM and RINEX file data and site interruption log information to users through HTTP network transmission. The device supports batch management of ground-based augmentation station RTCM data streams with Windows and Linux systems, and can realize automatic RINEX format conversion and visual control and display.

The present invention also relates to an electronic device, comprising:

at least one processor; and,

a memory communicatively connected to the at least one processor; wherein,

The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform the method described.
