[0003] The measurement work at the site of vehicle manufacturing and maintenance is increasingly favoring wireless connection devices. For example, low-power Bluetooth is widely used in terminals due to its low power consumption. Wireless vernier calipers, wireless multimeters, wireless wheel gauges and other measurement-related equipment almost all rely on wireless technology to interact with terminals for data. The premise of data interaction between measurement tools and terminals is mutual connection. At present, the connection methods are divided into hardware connection and software connection. Hardware connection requires additional insertion of receivers on the terminal. The receivers of different manufacturers and different devices are different, which leads to the need for more interfaces and larger volumes of terminals, which is inconvenient for workers to carry and operate. The other is software connection, which can be achieved by installing the software developed by the tool manufacturer to the terminal, but the software developed by different tool manufacturers is different, and different software needs to be switched in actual use. In addition, the upstream system needs to be connected with different manufacturers, which increases the difficulty of system development. When additional measurement tools from other manufacturers are used in the future, the system often needs to be upgraded and adapted, which increases maintenance costs. Summary of the invention

The illustrative embodiments of the present disclosure and their descriptions are used to explain the present disclosure and do not constitute an improper limitation on the present disclosure.

[0038] Figure 1 It is a schematic diagram of the overall flow of the measurement tool data collection method based on the wireless communication protocol of this embodiment. DETAILED DESCRIPTION

[0039] The present disclosure is further described below in conjunction with the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present disclosure. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present disclosure belongs.

[0041] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0042] Explanation of terms

[0043] ETL data processing (Extract, Transform and Load) is the process of extracting, transforming and loading data from different source systems. In the ETL data processing process, there are usually multiple steps involved, including connecting to the source system, executing queries, applying transformation rules, performing validation and error handling, etc.

[0044] SDK software development kit (Software Development Kit, SDK) is generally a collection of development tools for software engineers to build application software for specific software packages, software frameworks, hardware platforms, operating systems, etc.

[0045] API (Application Programming Interface) is a set of predefined functions that aims to provide applications and developers with the ability to access a set of routines based on certain software or hardware without having to access the source code or understand the details of the internal working mechanism.

[0046] At present, there are two types of connection methods: hardware connection and software connection. Hardware connection requires additional insertion of a receiver on the terminal. The receivers of different manufacturers and different devices are different, which results in the terminal requiring more interfaces and a larger size, which is inconvenient for workers to carry and operate. The other is software connection, which can be achieved by installing the software developed by the tool manufacturer into the terminal. However, the software developed by different tool manufacturers is different, and different software needs to be switched in actual use. In addition, the upstream system needs to be connected with different manufacturers, which increases the difficulty of system development. When additional measuring tools from other manufacturers are used in the future, the system often needs to be upgraded and adapted, which increases maintenance costs. In order to solve the above problems, the present disclosure proposes a data acquisition method and system for measuring tools based on a wireless communication protocol. There is no need to switch software during use, which improves work efficiency. The data acquisition system interacts with the upstream system in a unified manner, which reduces its development cost and improves applicability.

[0047] Embodiment 1

[0048] like Figure 1 As shown, this embodiment provides a measurement tool data collection method based on a wireless communication protocol, comprising the following steps:

[0049] Step 1: Receive the work order data sent by the upstream system;

[0050] Step 2: Perform ETL processing on the work order data to obtain the processed work order data;

[0051] Specifically including data extraction, data conversion and data loading;

[0052] Data extraction: The process of extracting data from one or more data sources. It usually involves extracting data from different data sources and converting it into a standard format for processing and analysis in the target system.

[0053] Data conversion: The process of processing and converting data extracted from a data source so that it can be analyzed and used in a target system. This usually involves operations such as cleaning, integrating, formatting, and calculating data.

[0054] Data loading: The process of loading extracted and transformed data into the target system.

[0055] Step 3: Perform logical processing on the processed work order data and classify the inspection points;

[0056] In this embodiment, the detection point items are divided into qualitative judgment item points and quantitative judgment item points, and the types of the detection points are distinguished by adding a type field and assigning values ​​respectively;

[0057] For example, if the quantitative value is 0 and the qualitative value is 1, when filtering the items that need to be quantitatively detected, you only need to filter type equal to 0 to filter out all the items that need quantitative detection.

[0058] Step 3: Select the test points that need to be quantitatively tested according to the test point classification results, determine the type of wireless measuring tool to be connected, and perform actual operations according to the work order task items;

[0059] The measurement data of each measuring tool is directly filled into the corresponding inspection items of the APP without manual filling.

[0060] Step 4: Communicate with the wireless measuring tool based on a preset wireless communication protocol and transmit the measurement data of the wireless measuring tool back;

[0061] The wireless measuring tool in this embodiment can be a wireless vernier caliper, a wireless multimeter, a wireless wheel gauge, and other measurement-related equipment, etc. However, the present invention does not limit the brand of the measuring tool, and can also be applied to other types of corresponding measuring tools.

[0062] In this embodiment, the preset wireless communication protocol includes a device compatibility protocol, an interface document protocol, and an operating system running on the measuring tool.

[0063] In this embodiment, the wireless communication protocol adopts the Bluetooth protocol, and the device compatibility protocol: the wireless measuring tool must meet Bluetooth 4.0 and above. The wireless measuring tool should support common wireless communication protocols, including Bluetooth Low Energy (BLE), which will allow the measuring tool to communicate with the device.

[0064] The interface document protocol includes SDK and API. SDK contains necessary library files, code examples, development documents and debugging tools; API includes rules for accessing measuring instruments, including data reading, parameter configuration and device control rules. Provide detailed technical documentation and sufficient code examples to guide developers on how to use SDK and API. Documentation should include interface description, function description, configuration guide and troubleshooting manual.

[0065] In addition to the compatibility of the protocol itself, it should also be ensured that the relevant software and drivers of the wireless measuring instrument can run on the required operating systems, such as Windows, Linux, and various mobile operating systems, such as iOS and Android.

[0066] The communication process with the wireless measuring tool includes BLE pairing, BLE binding and data transmission;

[0067] The BLE pairing process includes:

[0068] Step 401: Broadcasting and scanning: Device A (e.g., a mobile terminal) turns on Bluetooth and sets it to discoverable mode, and starts broadcasting its existence. Device B (e.g., a Bluetooth vernier caliper) is also broadcasting, looking for connectable devices. The Bluetooth adapter of device A starts scanning the surrounding Bluetooth signals and displays the detected devices in a list, including device B.

[0069] Step 402: Establishing a connection: The user selects device B from the Bluetooth device list of device A and attempts to establish a connection. Device A sends a connection request to device B, and device B confirms the connection request, and a connection is established between the two devices.

[0070] Step 403: Initiate a pairing request: Once the connection is established, device A (or device B, depending on who is the initiator of the pairing request) sends a pairing request packet to the other party.

[0071] Accepting pairing request: After receiving the pairing request, device B prompts the user whether to accept the pairing. After the user confirms to accept the pairing, device B sends a pairing response packet to device A.

[0072] Step 404: Generate a pairing key: During the pairing process, the two devices use an encryption algorithm (such as elliptic curve Diffie-Hellman key exchange) to generate a 128-bit pairing key. This key is used for subsequent communication encryption.

[0073] Step 405: Verify the pairing key: Device A and device B each verify whether the generated pairing keys are consistent. If they are consistent, the pairing is successful; otherwise, the pairing fails.

[0074] Step 406: Pairing is completed: If the pairing key verification is successful, the pairing process between device A and device B is completed. At this point, the two devices can begin secure data transmission and communication.

[0075] The BLE bonding process includes:

[0076] Step 407: In BLE, bonding is usually done automatically during the pairing process, specifically by storing a long-term key (LTK): During the pairing process, device A and device B generate a long-term key (LTK) in addition to the pairing key. This LTK is stored in the memory of both devices for subsequent fast connection and encryption.

[0077] Step 408: Fast reconnection: When device A and device B need to connect again, they can directly use the previously stored LTK for encrypted connection without having to go through the full pairing process again. This greatly speeds up the connection speed and improves the user experience.

[0078] The security of BLE pairing and bonding is mainly reflected in the generation and verification process of pairing keys and long-term keys. These keys are generated through secure encryption algorithms to ensure data security during communication.

[0079] After the connection is established, the mobile terminal and the measurement tool can perform data transmission. The data transmission follows the communication protocol defined in the BLE protocol stack.

[0080] In the BLE standard, the protocol consists of two parts: the controller and the host, as well as the interface HCI (Host Controller Interface) between the two. The host layer sets the broadcast data and other communication parameters through the interface defined by the HCI layer.

[0081] BLE data structures and formats are key to ensuring efficient communication between devices.

[0082] The BLE data structure has two types: LL layer data and L2CAP layer data. In this embodiment, the LL layer data structure is selected. The LL layer data packet format takes the LL layer data packet after connection as an example, and its format is as follows:

[0083] Preamble: 1 byte, depending on the first bit of the Access Address, it has two possible values: 0x55 or 0xAA.

[0084] Access Address: used to identify the receiver ID or air packet identity. When Access Address is equal to 0x8e89bed6, it is a broadcast packet; otherwise, it is a data packet. The data packet Access Address is a 32-bit random value.

[0085] PDU (Protocol Data Unit): Protocol data unit, the first two bytes are fixed as LL header (1 byte long) and payload length (1 byte long, also known as data length).

[0086] CRC: 24-bit check value, mainly used to check the content of the PDU data.

[0087] Step 5: Confirm the returned measurement data.

[0088] It should be noted that different measurement data are converted and transmitted in Bluetooth format and stored in corresponding storage media, and then connected to the PC or other devices that need to obtain the measurement results through the storage medium through structures. This method is suitable for contact transmission of data to a specific device, especially for the transmission of confidential data.

[0089] The above solution solves the problem of incompatibility of measurement tool software from different manufacturers, and there is no need to switch software when using it, which improves work efficiency. The data acquisition system is unified and interacts with the upstream system, which reduces its development cost and improves its applicability.

[0109] In addition to the compatibility of the protocol itself, it should also be ensured that the relevant software and drivers of the wireless measuring instrument can run on the required operating systems, such as Windows, Linux, and various mobile operating systems, such as iOS and Android.

[0110] The communication process with the wireless measuring tool includes BLE pairing, BLE binding and data transmission;
