Description

Technical Field

[0001] This application relates to the field of railway vehicle measurement, and more particularly to a digital measurement system for railway vehicle bogie components. Background Technology

[0002] In the maintenance and new construction of bogies for rail vehicles, especially EMU trains, numerous key components (such as frames, wheelsets, and axle boxes) require geometric dimension measurements. Traditional methods generally rely on manual measurement using various digital measuring tools (such as calipers and micrometers), followed by manual transcription of the results into paper forms or spreadsheets. Given the hundreds of measurement points generated by the complex structure of the bogie, this method places a heavy burden of data recording and verification on-site personnel. In the daily high-intensity, repetitive work, manual transcription is prone to errors such as misrecording, omissions, and misreading, directly impacting maintenance quality and production efficiency, and creating difficulties and risks for subsequent data traceability, quality analysis, and process optimization. Therefore, a digital solution capable of automatically collecting, identifying, and uploading measurement data is urgently needed to free up manpower, eliminate human error, and achieve full traceability of the measurement process. Summary of the Invention

[0003] The main objective of this application is to propose a digital measurement system for rail vehicle bogie components, which enables automatic acquisition of measurement data, avoids human error, and ensures data traceability.

[0004] To achieve the above objectives, a first aspect of this application provides a digital measurement system for a railway vehicle bogie component, comprising: The integrated receiver includes a processor, a first receiver, and a second receiver. The first specification measuring instrument has a built-in first transmitter. The first transmitter is used to send the first measurement parameters measured by the first specification measuring instrument to a first receiver. The first receiver has a first header identifier corresponding to the first transmitter pre-stored. The second specification measuring instrument has a built-in second transmitter. The second transmitter is connected to a preset port of the second receiver for communication. The second transmitter is used to send the second measurement parameters measured by the second specification measuring instrument to the preset port. Third-specification measuring tools; The SATA transmitter communicates with the third-specification measuring instrument. The SATA transmitter has a pre-stored second header identifier. The SATA transmitter is used to read the third measurement parameters measured by the third-specification measuring instrument and send the third measurement parameters and the second header identifier to the second receiver. The processor is configured to parse the first measurement parameter through the first receiver based on the first header identifier, and parse the second measurement parameter and the third measurement parameter through the second receiver based on the preset port and the second header identifier, respectively, and upload the parsed first measurement parameter, second measurement parameter and third measurement parameter to the data platform.

[0005] Furthermore, in some embodiments, the first measurement parameter is parsed by the first receiver based on the first header identifier, including: In response to the first receiver receiving the first data stream transmitted from the outside, the first measurement parameter is parsed from the first data stream based on the first packet header identifier.

[0006] Furthermore, in some embodiments, the second receiver parses the second measurement parameter and the third measurement parameter according to the preset port and the second header identifier, respectively, including: In response to the second receiver receiving a second data stream transmitted from the outside, it determines whether the port receiving the second data stream is a preset port. If so, the second data stream will be parsed into the second measurement parameter; If not, the third measurement parameter is parsed from the second data stream based on the second header identifier.

[0007] Furthermore, in some embodiments, the data platform pre-stores a mapping table between the header identifier and port number and the gauge attributes, whereby the gauge attributes include gauge name, measurement number, and gauge specifications. The parsed first, second, and third measurement parameters are uploaded to the data platform, including: Obtain the mapping relationship table from the data platform; Based on the first header identifier, the system queries the mapping table for the first gauge attribute corresponding to the first measurement parameter, and binds the first gauge attribute to the first measurement parameter to generate structured first work order data. Based on the port number of the preset port, the second gauge attribute corresponding to the second measurement parameter is queried in the mapping table, and the second gauge attribute is bound to the second measurement parameter to generate structured second work order data; Based on the second header identifier, the third gauge attribute corresponding to the third measurement parameter is queried in the mapping relationship table, and the third gauge attribute is bound to the third measurement parameter to generate structured third work order data; The data for the first work order, the second work order, and the third work order are uploaded to the data platform for storage and management.

[0008] Furthermore, in some embodiments, the above-mentioned digital measurement system also includes a repeater, which integrates a third receiver, a fourth receiver and a third transmitter. The third transmitter is communicatively connected to the first receiver and the second receiver, the third receiver is communicatively connected to the first transmitter, and the fourth receiver is communicatively connected to the second transmitter and the SATA transmitter. The repeater is configured to receive a first measurement parameter transmitted by a first transmitter via a third receiver, and to receive a second measurement parameter transmitted by a second transmitter, a third measurement parameter transmitted by a SATA transmitter, and a second header identifier via a second receiver. It is also configured to send the first measurement parameter, the second measurement parameter to a preset port, and the third measurement parameter and the second header identifier to the second receiver via the third transmitter.

[0009] Furthermore, in some embodiments, the integrated receiver also includes a digital display screen, which is communicatively connected to the first receiver and the second receiver, and the digital display screen is equipped with a human-machine interface. The human-computer interaction interface is used to display the first measurement parameter, the second measurement parameter, and the third measurement parameter in real time.

[0010] Furthermore, in some embodiments, the integrated receiver is a handheld device or a desktop integrated device, and the integrated receiver housing integrates a first receiver and a second receiver.

[0011] Furthermore, in some embodiments, the first specification measuring tool, the second specification measuring tool, and the third specification measuring tool include one of a digital inside micrometer, a digital outside micrometer, a digital vernier caliper, a digital depth gauge, and a digital dial indicator.

[0012] Furthermore, in some embodiments, the first transmitter, the second transmitter, and the third transmitter are Bluetooth transmitters, Wi-Fi transmitters, or wireless radio frequency transmitters of a specific frequency band.

[0013] Furthermore, in some embodiments, the SATA transmitter is connected to a third-specification measuring instrument via a standard wired interface, which may be a USB interface, an RS-232 interface, or an RS-485 interface.

[0014] The embodiments of the first aspect of this application have the following beneficial effects: By integrating the first and second receivers through a unified receiver and cooperating with pre-set header identifiers and dedicated ports, an open multi-source data access center is constructed. This system can automatically identify and parse measurement parameters from first-specification measuring tools (via the first header identifier), second-specification measuring tools (via a preset port), and third-specification measuring tools adapted via a SATA transmitter (via the second header identifier). This achieves seamless compatibility and unified management of measuring tools of different specifications and interface protocols, thereby eliminating the traditional reliance on manual paper records on the production site. It enables real-time, automatic, and error-free acquisition and uploading of measurement data, greatly improving the efficiency and accuracy of measurement operations. Simultaneously, based on the data association mechanism of header identifiers and ports, it ensures that each piece of measurement data can be automatically bound to a specific measuring tool and measurement task, forming a complete and reliable digital traceability chain, providing a data foundation for quality control and process optimization of bogie maintenance and new manufacturing.

[0022] In the maintenance and new construction of bogies for rail vehicles, especially EMU trains, numerous key components (such as frames, wheelsets, and axle boxes) require geometric dimension measurements. Traditional methods generally rely on manual measurement using various digital measuring tools (such as calipers and micrometers), followed by manual transcription of the results into paper forms or spreadsheets.

Therefore, a digital solution capable of automatically collecting, identifying, and uploading measurement data is urgently needed to free up manpower, eliminate human error, and achieve full traceability of the measurement process.

[0023] To address these issues, this application proposes a digital measurement system for rail vehicle bogie components, which enables automatic acquisition of measurement data, avoids human error, and ensures data traceability.

[0024] This application provides a digital measurement system for a railway vehicle bogie component, which is specifically described through the following embodiments.

[0025] Reference Figures 1 to 4 As shown, Figure 1 This is an optional framework diagram of the digital measurement system for rail vehicle bogie components provided in this application embodiment. Figure 2 This is an optional structural diagram of the integrated receiver provided in the embodiments of this application. Figure 3 This is an optional structural diagram of the SATA transmitter provided in the embodiments of this application. Figure 4 This is an optional schematic diagram of a SATA transmitter connected to a third-specification measuring instrument according to an embodiment of this application. The digital measurement system includes a comprehensive receiver 110, a first-specification measuring instrument 120, a second-specification measuring instrument 130, a third-specification measuring instrument 140, and a SATA transmitter 150. The comprehensive receiver 110 includes a processor 111, a first receiver 112, a second receiver 113, and a digital display screen 114. The digital display screen 114 is communicatively connected to the first receiver 112 and the second receiver 113, respectively. A human-machine interface is configured in the digital display screen 114. The first-specification measuring instrument 120 has a built-in first transmitter 121, and the second-specification measuring instrument 130 has a built-in second transmitter 131. The second transmitter 131 is communicatively connected to a preset port of the second receiver 113. The SATA transmitter 150 is communicatively connected to the third-specification measuring instrument 140.

[0026] In a preferred embodiment, the first specification measuring instrument 120, the second specification measuring instrument 130, and the third specification measuring instrument 140 include one of a digital inside micrometer, a digital outside micrometer, a digital vernier caliper, a digital depth gauge, and a digital dial indicator.

[0027] The first transmitter 121 is used to send the first measurement parameters measured by the first specification gauge 120 to the first receiver 112. The first receiver 112 has a first header identifier pre-stored corresponding to the first transmitter 121. The second transmitter 131 is used to send the second measurement parameters measured by the second specification gauge 130 to a preset port. The SATA transmitter 150 has a second header identifier pre-stored. The SATA transmitter 150 is used to read the third measurement parameters measured by the third specification gauge 140 and send the third measurement parameters and the second header identifier to the second receiver 113.

[0028] In a preferred embodiment, the integrated receiver 110 is a handheld device or a desktop integrated device, and the integrated receiver 110 housing integrates a first receiver 112 and a second receiver 113.

[0029] In a preferred embodiment, the first transmitter 121 and the second transmitter 131 include, but are not limited to, any one of a Bluetooth transmitter, a Wi-Fi transmitter, or a wireless radio frequency transmitter in a specific frequency band; this application does not impose specific limitations on these. Furthermore, the SATA transmitter 150 is connected to the third-specification measuring instrument 140 via a standard wired interface, which includes, but is not limited to, any one of a USB interface, an RS-232 interface, or an RS-485 interface; this application does not impose specific limitations on these.

[0030] Furthermore, the processor 111 is configured to parse the first measurement parameter according to the first header identifier through the first receiver 112, and parse the second measurement parameter and the third measurement parameter respectively according to the preset port and the second header identifier through the second receiver 113, and upload the parsed first measurement parameter, second measurement parameter and third measurement parameter to the data platform 160.

[0031] The human-computer interaction interface is used to display the first measurement parameter, the second measurement parameter, and the third measurement parameter in real time.

[0032] It should be noted that, in this embodiment, the first receiver 112 and the second receiver 113 are integrated through the comprehensive receiver 110, and an open multi-source data access center is constructed in conjunction with the pre-set header identifier and dedicated port. This system can automatically identify and parse measurement parameters from the first specification gauge 120 (via the first header identifier), the second specification gauge 130 (via the preset port), and the third specification gauge 140 (via the second header identifier) ​​adapted through the SATA transmitter 150. This achieves seamless compatibility and unified management of measuring tools of different specifications and interface protocols, thereby eliminating the traditional reliance on manual paper records on the production site. It enables real-time, automatic, and error-free acquisition and uploading of measurement data, greatly improving the efficiency and accuracy of measurement operations. Simultaneously, based on the data association mechanism of the header identifier and port, it ensures that each piece of measurement data can be automatically bound to a specific gauge and measurement task, forming a complete and reliable digital traceability chain, providing a data foundation for quality control and process optimization of bogie maintenance and new manufacturing.

[0033] In a preferred embodiment, the above-mentioned parsing of the first measurement parameter by the first receiver 112 according to the first header identifier specifically includes the following steps: in response to the first receiver 112 receiving the first data stream transmitted from the outside, parsing the first measurement parameter from the first data stream according to the first header identifier.

[0034] In a preferred embodiment, the second receiver 113 parses the second measurement parameter and the third measurement parameter according to the preset port and the second header identifier, respectively, including: in response to the second receiver 113 receiving the second data stream transmitted from the outside, determining whether the port receiving the second data stream is the preset port; if yes, then parsing the second data stream into the second measurement parameter; if no, then parsing the third measurement parameter from the second data stream according to the second header identifier.

[0035] Furthermore, the data platform 160 pre-stores a mapping table between the header identifier and port number and the gauge attributes, wherein the gauge attributes include, but are not limited to, gauge name, measurement number, and gauge specifications.

[0036] In a preferred embodiment, uploading the parsed first measurement parameter, second measurement parameter, and third measurement parameter to the data platform 160 includes: obtaining a mapping relationship table from the data platform 160; querying the mapping relationship table for the first gauge attribute corresponding to the first measurement parameter based on the first package header identifier, and binding the first gauge attribute to the first measurement parameter to generate structured first work order data; querying the mapping relationship table for the second gauge attribute corresponding to the second measurement parameter based on the port number of a preset port, and binding the second gauge attribute to the second measurement parameter to generate structured second work order data; querying the mapping relationship table for the third measurement parameter corresponding to the third measurement parameter based on the second package header identifier, and binding the third gauge attribute to the third measurement parameter to generate structured third work order data; and uploading the first work order data, second work order data, and third work order data to the data platform 160 for storage and management.

[0037] In one specific embodiment of this application, the human-machine interface of the integrated receiver 110 provides a "receiver header setting" interface, the core function of which is to realize the binding and unbinding operations between the integrated receiver 110 and various measuring tools, and to query and set the data packet header identifier for receivers that support this function. The interface provides options for a first-specification gauge 120, a second-specification gauge 130, and a third-specification gauge 140 via a drop-down list. Its underlying logic reflects the compatibility handling of the different communication protocols of the gauges of different specifications: when the first-specification gauge 120 is selected, the integrated receiver 110 will operate on the inserted YH receiver (i.e., the first receiver 112). The non-volatile memory inside the receiver is used to store the unique MAC address of the gauge bound to it and the programmable first header identifier (such as "@A1"); when the third-specification gauge 140 is selected, the integrated receiver 110 will configure the SATA transmitter 150, which also has a pre-stored configurable second header identifier; when the second-specification gauge 130 is selected, the interface will disable the header setting function, because the identification of the second-specification gauge 130 depends on the physical or logical connection with a specific preset port on the second receiver 113. Its data stream already contains a fixed-format identifier, so there is no need and it is not possible to set the header separately at the receiving end. During binding, the operator must first accurately select the physical port number to which the receiver is inserted from the "Port Selection" drop-down box according to the actual hardware connection (the port identification is clearly printed on the repeater 170 or integrated receiver 110). After selecting the gauge and port, click the "Open" button to initialize port communication. Upon successful completion, "open success" will be displayed in the information prompt area. Next, the operator clicks the "Scan" button. The integrated receiver 110 will search for nearby wireless devices within a short time and display a list of scanned devices (including MAC address, device name, and signal strength) in the scan results area. After selecting the transmitter corresponding to the target gauge from the list, the operator clicks the "Bind" button. The integrated receiver 110 will then write the transmitter's MAC address into its memory, establishing an exclusive link. The information prompt area will display "Bonded MAC: [Specific Address]" for confirmation. If the gauge needs to be changed, the "Unbind" button can be clicked to clear the stored MAC address. The "Query Binding" button allows you to check the current port binding status at any time. For the first receiver 112 or SATA transmitter 150 that supports header configuration, the header identifier configuration is completed within the same interface. The operator enters the preset header string (usually starting with "@") in the designated input box and clicks the "Header Setting" button. The identifier is then written into the memory of the first receiver 112 or SATA transmitter 150, and a success message is displayed in the information area. The currently stored header identifier content can be verified using the "Header Query" button.The header (first header identifier or second header identifier) ​​set in this step is crucial for subsequent automatic data identification. In the subsequent "Grip Management" function, this physical identifier needs to be bound to the gauge attributes such as "measurement number" and "tool name" to form structured work order data (i.e., first work order data, second work order data, and third work order data). This completes the full mapping chain from physical connection (MAC / port) to logical identifier (header) and then to management information (gauge attributes) at the system level, laying the foundation for fully automatic and traceable archiving of measurement data.

[0038] Furthermore, refer to Figure 5 and Figure 6 As shown, Figure 5 This is another optional flowchart of the digital measurement system for rail vehicle bogie components provided in the embodiments of this application. Figure 6 This is an optional structural diagram of the repeater provided in the embodiments of this application. The above-mentioned digital measurement system also includes a repeater 170, which integrates a third receiver 171, a fourth receiver 172 and a third transmitter 173. The third transmitter 173 is communicatively connected to the first receiver 112 and the second receiver 113, respectively. The third receiver 171 is communicatively connected to the first transmitter 121, and the fourth receiver 172 is communicatively connected to the second transmitter 131 and the SATA transmitter 150, respectively.

[0039] The repeater 170 is configured to receive the first measurement parameters transmitted by the first transmitter 121 through the third receiver 171, and receive the second measurement parameters transmitted by the second transmitter 131, the third measurement parameters transmitted by the SATA transmitter 150, and the second header identifier through the second receiver 113. The repeater 170 is also configured to send the first measurement parameters to the first receiver 112, the second measurement parameters to a preset port, and the third measurement parameters and the second header identifier to the second receiver 113 through the third transmitter 173.

[0040] It should be noted that the third transmitter 173 includes, but is not limited to, any one of Bluetooth transmitters, Wi-Fi transmitters, and wireless radio frequency transmitters in a specific frequency band. In a preferred embodiment, the repeater 170 is introduced into the digital measurement system provided in this application to resolve the contradiction between the actual physical space span of industrial sites and the limitations of wireless communication distance. In industrial sites such as the maintenance of railway vehicle bogies, the work area of ​​a shift is usually irregular, with a span of 40 to 50 meters, while the reliable communication distance between a single integrated receiver 110 and the measuring instrument transmitter is generally less than 10 meters. If only one integrated receiver 110 is used, its effective measurement range can only cover an area with a radius of about 10 meters, which cannot meet the needs of large-scale operations. By adding repeaters 170, the wireless signal coverage network of the system can be extended. The reason for choosing to add repeaters 170 instead of directly adding more integrated receivers 110 to expand the range is due to a comprehensive consideration of equipment portability, power consumption, and ease of operation. The integrated receiver 110 integrates a processor 111, a digital display screen 114, and a first receiver 112 and a second receiver 113. The device is large in size, heavy in weight, and consumes a lot of power, making it inconvenient to move and carry frequently on site. The repeater 170 is designed as a screenless miniaturized module. It is small in size, light in weight, and low in power consumption. It can operate for a long time and is easy for operators to carry or flexibly deploy near the measurement point, thus realizing the economical and efficient expansion of the measurement network coverage.

[0041] In practical configuration, the system can be flexibly deployed according to the size of the work area of ​​the shift. For example, in a large work shift, a networking mode of "one integrated receiver 110 paired with multiple repeaters 170" can be adopted. The integrated receiver 110, as the central data processing and display node, can cover a radius of about 20 meters; each repeater 170 can extend the wireless signal reception range of the measuring instruments by about 10 meters. Through this master-slave collaborative architecture, the system can build a distributed measurement network covering the entire irregular work area, ensuring centralized data management and display while enabling measurement activities to be carried out freely in a wide space, effectively overcoming the bottleneck of the limited measurement range of traditional single receivers.

[0042] In one specific embodiment of this application, the workflow of the digital measurement system is as follows: Before operation, ensure that the integrated receiver 110 and its repeater 170 module are powered on and connected to the network where the CAA data platform 160 is located. Prepare a digital vernier caliper A (a first specification measuring instrument 120) and its built-in first transmitter 121. First, physically bind the measuring instrument to the integrated receiver 110: insert the first transmitter 121 into the designated port of the integrated receiver 110. Enter the "Receiver Head Setting" function interface through the human-machine interface of the integrated receiver 110, select the specification as "first specification measuring instrument 120" and select the corresponding port number, and perform the port opening operation. After the function interface prompts "open success", start the Bluetooth scanning function, select the MAC address of the digital vernier caliper A in the list of discovered devices, and perform the binding operation. The function interface prompts "Bonded", indicating that the first transmitter 121 of the digital vernier caliper A has successfully established an exclusive connection with the first receiver 112. Next, the logical identifier is set: enter the preset first header identifier, such as "@A1", in the input box, and click the set button. The integrated receiver 110 confirms "Header set @A1". At this time, click the send button of the digital vernier caliper A, and the integrated receiver 110 can receive the real-time measurement data sent by the digital vernier caliper A, indicating that the first receiver 112 can correctly identify and parse the data stream from the digital vernier caliper A according to the first header identifier.

[0043] Next, after completing the hardware binding and header setting, a mapping relationship between the first header identifier and the gauge metadata needs to be established in the data platform 160 to achieve data traceability. The operator enters the "Grip Management" function interface of the integrated receiver 110 and performs the operation of adding a new gauge record. In the new record row, the "Tool Name" (e.g., "Digital Caliper-001"), "Measurement Number" (e.g., "CAL-2025-001"), and the crucial "Serial no." field corresponding to the digital vernier caliper A are entered sequentially. This field must be filled with the first header identifier "@A1" set in the previous step. This operation essentially creates or updates a key record in the "Mapping Relationship Table" in the data platform 160, thereby permanently associating the physical gauge, its logical identifier (header), and its gauge attributes, laying the foundation for the automated archiving and traceability of each subsequent measurement data.

[0044] To enable automatic reporting of measurement data to the data platform 160 (CAA system), the integrated receiver 110 needs to be configured for network connectivity. First, in the "System Settings" interface of the human-machine interface, enter and save the complete URL address of the CAA data platform 160. Next, in the "Network Settings" interface, connect the integrated receiver 110 to the local area network where the CAA platform is located. Configure a dynamic or static IP address as needed. Finally, start the built-in data service: in the "Network Card Server" settings interface, ensure that the "Local Address" and "Detection Address" are consistent, and then start the detection service. After the system indicates successful detection, the integrated receiver 110 will operate as a data service node on the specified IP and port (e.g., 192.168.155.36:9000). At this point, the integrated receiver 110 has the ability to access the CAA data platform 160 and also provides a standard API interface (e.g., / api / v1 / plantA / tasks) for receiving measurement tasks and uploading data, completing the bidirectional communication link with the upper-layer data platform 160.

[0045] After completing all the above settings, the integrated receiver 110 enters standby mode. When the operator uses the digital vernier caliper A to measure bogie components, they only need to press the send button on the digital vernier caliper A after obtaining the reading. The first receiver 112 of the integrated receiver 110 automatically captures the data and instantly completes the identification of the data source and parameter parsing based on the header "@A1". The processor 111 of the integrated receiver 110 then packages the parsed measurement value, timestamp, and header identifier "@A1", and through the established network connection, calls the API interface of the preset CAA data platform 160. It queries the corresponding gauge attribute in the mapping table in the background based on the header identifier "@A1", and then associates the measurement result with the specific caliper with the measurement number "CAL-2025-001" and its preset work order, thereby generating a complete, accurate work order data that does not require manual entry, and then uploads the work order data to the CAA data platform 160. This process can complete the entire process from binding to the first effective measurement within five minutes, realizing end-to-end automatic collection and traceable management of measurement data.

[0046] Furthermore, it should be noted that after powering on, the human-machine interface software of the integrated receiver 110 prominently displays the currently bound work group name on the main interface, facilitating quick identification and management of field equipment. The integrated receiver 110 will print key status information of the data platform 160 in real time on the interface, including network detection address and port. If an anomaly is detected (such as a missing address or a port of 0), it will prompt the user to check the physical network card connection, network connectivity, or service configuration to ensure the data channel is ready. When a measurement work order is received from the CAA data platform 160, a message indicating successful reception will be displayed, along with the work order storage path. When the integrated receiver 110 transmits data back, the transmission status will also be updated synchronously. Simultaneously, the integrated receiver 110 provides an "Automatic Processing" option. When enabled, the integrated receiver 110 will automatically jump to the task interface and start data detection upon receiving a work order from the CAA data platform 160, achieving seamless integration of task reception and measurement.

[0047] When the operator clicks the "Task to be Measured" button on the main interface or is redirected by the automated process, they enter the "Work Order Management" function interface. In this interface, the operator can manually select and open a work order file sent from the CAA data platform 160 to the integrated receiver 110 from a specified directory. After opening the work order, the integrated receiver 110's human-machine interface switches to measurement mode, awaiting data input from various measuring instruments. This task is presented in a tab format and can be manually terminated by clicking the close button on the tab. In "Automated Processing" mode, once all measurement items within the work order have completed data acquisition, the integrated receiver 110 automatically closes the current task tab and returns to the main interface, requiring no manual intervention, thus optimizing the measurement workflow and reducing operational steps.

[0048] For work orders where data acquisition has been completed, the work order can be managed and reported in the "Measured Tasks" interface of the human-machine interface. In the "Measured Tasks" interface, operators can select and open the work order file with the measurement results filled in from the local SendCaa directory. The interface clearly displays the file name, the measurement results of each point, and the qualification status judgment. The most critical function is the "Upload" button. After the operator clicks it, the integrated receiver 110 will send the complete work order data packet to the CAA data platform 160 according to the receiving end URL (i.e., the data receiving interface of the CAA data platform 160) configured in the "System Settings". At the same time, the integrated receiver 110 will provide feedback on whether the upload was successful or failed; if the upload fails, the network connection, network card status, and server reachability must be checked in sequence. The interface also intuitively displays the currently set receiving end URL, which is convenient for operators to quickly verify and ensure that the return path is accurate.

[0049] The core configuration of the integrated receiver 110 is achieved through the "Configuration Related" function area on the main interface. This function area is used to navigate to the "Gazette Management" function interface, the "Receiver Header Setting" function interface, the "System Settings" function interface, and the "Network Card Server" function interface. The "Gazette Management" function interface is used to establish and maintain the core mapping database for data traceability. In the "Gazette Management" function interface, operators can create new records using the "Add" button. Three key fields must be entered: "Tool Name," "Measurement Number," and "Serial No." (i.e., header identifier) ​​to uniquely identify a gauge. The "Delete" button removes selected records. All add, delete, and modify operations must be submitted using the "Confirm" button before being persistently saved to the database. This database is a key logical component of the integrated receiver 110: when the integrated receiver 110 parses the header information from the measurement data, it indexes the corresponding gauge measurement number and other attributes, recombining them into a data packet with complete traceability information that meets the requirements of the CAA data platform 160, thus completing the conversion from raw data to standardized quality records. The remaining configuration functions are used for gauge binding, network parameter settings, and service detection control, respectively.

[0050] It should also be noted that the "System Settings" function interface of the integrated receiver 110's human-machine interface provides configuration options for several core parameters to define the behavior logic of data processing and uploading. Operators can select the "Do not upload non-conforming items" option based on the quality control requirements of the specific measurement task. When enabled, the integrated receiver 110 will automatically ignore data points deemed non-conforming when it parses measurement results and will not send them to the CAA data platform 160. To ensure compatibility with gauges such as the second-specification gauge 130, which are identified via physical ports rather than data packet headers, the "System Settings" function provides a "Special Port" designation function. When this flag is enabled for a specific port, data from that port will be directly indexed in the database based on the port number, thus adapting to its inherent communication protocol. Regarding upload modes, the integrated receiver 110 supports two strategies: In the default mode, all data points within a measurement work order are collected and uploaded in a single package after completion; when the "Upload Item by Item" option is selected, the integrated receiver 110 will immediately send the results of each measurement item separately to the CAA data platform 160 after completion, achieving real-time data feedback. Furthermore, the "System Settings" interface is also used to input the work group information to which the equipment belongs. This work group information will be displayed on the main interface when the equipment starts up, facilitating on-site management and identification.
