[0022] This invention provides a method, apparatus, and computer device for connecting a sensor to a data acquisition and storage medium. The terms "first," "second," "third," "fourth," etc. (if present)," in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0023] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the connection method between the sensor and the data acquisition and storage medium in this invention includes:

[0024] Step S1: Obtain sensors with independent identification information and configure multiple candidate connection interfaces of the acquisition and storage medium to obtain multiple connection interfaces with unified attributes;

[0025] It is understood that the executing entity of this invention can be a connection device between the sensor and the data acquisition and storage medium, or it can be a terminal or a server; no specific limitation is made here. This embodiment of the invention will be described using a server as an example.

[0026] Step S2: Physically connect the sensor to any connection interface with the same properties in the data acquisition and storage medium to obtain the initial connection state;

[0027] Step S3: Use target recognition technology to identify the sensor in the initial connection state and obtain identification information;

[0028] Step S4: Based on the identification information, perform sensor information calibration and generate a sensor data acquisition scheme. The data acquisition scheme is used to collect physical change data of valve operation through the sensor and store the physical change data through the acquisition storage medium.

[0029] Specifically, the connection mechanism between the sensor and the data acquisition and storage medium, such as Figure 2 As shown, Figure 2 The location of the sensor's ID information storage medium is specified. Each sensor has independent identification information, and the connection interface of the data acquisition and storage medium is not unique. All data acquisition interfaces have uniform attributes (the key purpose of uniform attributes is to eliminate the need to consider how the sensor and data acquisition and storage medium should be connected; they can be connected arbitrarily. Sensors can be connected to the data acquisition and storage medium in any way, even if the interface is damaged, it can still be connected to other interfaces). Interface attributes include, but are not limited to, the type of acquisition signal, the accuracy of the acquisition signal, the physical connection style, etc. Figure 3As shown. The key to sensor identification lies in assigning a unique ID to any sensor with a standard signal output. The method of binding the ID is not limited to the following target identification technologies, such as 2D scanning identification (for example, a QR code label is attached to the sensor, and the collector has a scanning device to automatically obtain sensor information by scanning the code), chip identification (for example, an identification chip / storage circuit element is connected in the sensor signal connector or cable, which can store ID information), communication verification and information reading (common and easy-to-implement methods are added here), and RFID identification technology (an RFID code is installed inside the sensor, and the sensor's ID information is stored in the bias code information of the RFID code). The physical connection here includes, but is not limited to, any communication transmission and physical point-to-point insertion (conventional and universal). After the data acquisition storage medium and sensor are connected, the sensor information can be automatically obtained through ID information verification, and a corresponding acquisition strategy can be generated. The acquisition strategy includes, but is not limited to, automatically obtaining the corresponding algorithm, automatically obtaining the sensor's functional attributes, and automatically obtaining calibration information. (The key to obtaining calibration information is to know whether the sensor is within the compliant accuracy range, so as to distinguish whether the collected data is legal.) After obtaining the information, it is known what the sensor can collect. The user can then connect the sensor to the valve end. By connecting different types of sensors, all physical changes in the valve's operation can be transmitted to the data acquisition storage medium through the connection with the data acquisition storage medium. This connection includes, but is not limited to, communication transmission (communication methods are not limited to wireless communication, wired communication, Bluetooth communication, network communication), physical point-to-point direct transmission, etc.

[0030] In this invention, a unified interface specification and consistent connection interface design enable plug-and-play functionality between different types of sensors and the data acquisition and storage media, significantly improving system compatibility and flexibility. Employing various target recognition technologies, such as QR codes and RFID, enables rapid and automatic sensor identification, simplifying the connection and configuration process, reducing manual intervention, and improving efficiency. A unified design with multiple candidate connection interfaces ensures that even if one interface fails, other interfaces can still be used, enhancing system reliability and fault tolerance. Based on sensor functional attributes, calibration information, and corresponding algorithms, a targeted data acquisition scheme is automatically generated, ensuring more accurate and effective data on valve operation physical changes. Multiple physical connection methods are supported, including wireless communication, wired communication, Bluetooth communication, and network communication, meeting the connection requirements of different application scenarios. The automated identification and configuration process greatly reduces the workload during system maintenance and upgrades, improving system maintainability. This invention, applied in the field of valve diagnostics, possesses a reliable and convenient sensor information management mechanism, a highly convenient sensor usage mechanism, and a unified and broad backup interface strategy, enabling compatibility with a wider range of sensor types.

[0031] In one specific embodiment, the process of performing step S1 may specifically include the following steps:

[0032] By binding a unique identifier to the sensor, a sensor with independent identification information is obtained. The unique identifier includes the sensor ID.

[0033] Based on a unified interface specification, multiple candidate connection interfaces for the acquisition and storage medium are configured to obtain multiple connection interfaces with unified attributes, including the type of acquisition signal, the accuracy of the acquisition signal, and the physical connection style.

[0034] The unique identification information binding method includes at least one of the following: attaching a QR code label to the sensor; integrating an identification chip or storage circuit element into the sensor signal connection plug or cable; installing an RFID code inside the sensor, with the sensor's ID information stored in the bias code information of the RFID code.

[0035] Specifically,

[0036] In one specific embodiment, the connection interface attributes of the acquisition storage medium further include:

[0037] The type of signal acquired; the accuracy of the acquired signal; the physical connection style; wherein, the properties of all candidate connection interfaces of the acquisition storage medium are consistent, so that the sensor can be connected to any candidate connection interface, and even if any candidate connection interface is damaged, other candidate connection interfaces can still be used for connection.

[0038] Specifically, sensors are uniquely identified and bound to them, resulting in sensors with independent identification information, including a sensor ID. Specific binding methods include, but are not limited to: attaching a QR code label to the sensor containing its unique ID; integrating an identification chip or storage circuit element into the sensor signal connection plug or cable to store the sensor ID; and installing an RFID code inside the sensor, storing the sensor ID in the RFID code's offset information. Multiple candidate connection interfaces of the data acquisition and storage medium are configured based on a unified interface specification, resulting in multiple connection interfaces with unified attributes. These unified attributes include, but are not limited to: signal type (e.g., analog, digital); signal accuracy (e.g., 16-bit, 24-bit); and physical connection style (e.g., DB9, USB). This ensures that all candidate connection interface attributes of the data acquisition and storage medium remain consistent, allowing the sensor to be connected to any interface. The purpose of this design is to achieve plug-and-play functionality, eliminating the need to consider the correspondence between the sensor and the data acquisition and storage medium, and to improve system fault tolerance, ensuring that even if one interface fails, other interfaces can still be used for connection. The connection interface attributes of the data acquisition and storage medium may also include: the frequency range of the acquired signal; the voltage / current range of the acquired signal; the communication protocol type (e.g., RS-232, RS-485, 4-20mA, etc.); and the configuration of the data acquisition and storage medium to support diverse connection methods, including but not limited to: wireless communication (e.g., Wi-Fi, ZigBee, etc.); wired communication (e.g., Ethernet, CAN bus, etc.); Bluetooth communication; and network communication (e.g., TCP / IP, MQTT, etc.). Necessary hardware devices are integrated into the data acquisition and storage medium to support various identification technologies: an integrated QR code scanner for reading QR code tags on sensors; an integrated chip reader for reading identification chips in sensor connectors; and an integrated RFID reader for reading RFID codes inside sensors. Automatic identification and configuration algorithms are developed and integrated, enabling the data acquisition and storage medium to: automatically detect newly connected sensors; read the sensor's unique identification information; query a preset database based on the identification information to obtain detailed sensor information; and automatically generate acquisition strategies and data processing algorithms suitable for the sensor. By following the steps above, flexible connection and automatic configuration between the sensor and the data acquisition and storage medium can be achieved, greatly improving the ease of use and adaptability of the system. It is particularly suitable for scenarios such as valve diagnosis where different types of sensors need to be frequently replaced or added.

[0039] In one specific embodiment, the process of performing step S2 may specifically include the following steps:

[0040] Select any connection interface with uniform attributes on the data acquisition and storage medium. The connection interface with uniform attributes has a data acquisition signal type, data acquisition signal accuracy, and physical connection style that are compatible with the sensor.

[0041] The sensor is connected to the selected unified connection interface through a physical connection method, which includes at least one of the following: communication transmission connection, including wireless communication, wired communication, Bluetooth communication and network communication; physical point-to-point direct connection; confirming the completion of the physical connection between the sensor and the data acquisition and storage medium, and establishing the initial connection state.

[0042] Specifically, select a connection interface with uniform attributes on the data acquisition and storage medium: Check all available connection interfaces on the data acquisition and storage medium. Confirm that these interfaces have uniform attributes, including but not limited to: signal type (e.g., analog signal, digital signal); signal accuracy (e.g., 16-bit, 24-bit); physical connection style (e.g., DB9 interface, USB interface); verify that these attributes are compatible with the sensor to be connected. Connect the sensor to the selected connection interface with uniform attributes via physical connection method: Communication transmission connection: Wireless communication: such as using Wi-Fi, ZigBee, etc. to establish a connection. Wired communication: such as using Ethernet cable, serial cable, etc. Bluetooth communication: establish a short-range wireless connection via Bluetooth protocol. Network communication: such as establishing a connection on a local area network or the Internet via TCP / IP protocol. Physical point-to-point direct connection: such as using a standard interface (e.g., DB9, USB, etc.) to directly insert the sensor into the corresponding port of the data acquisition and storage medium. Confirm that the physical connection between the sensor and the data acquisition and storage medium is complete and establish the initial connection status: For wired connections, check whether the connection is secure and whether the signal is transmitted normally. For wireless connections, verify sufficient signal strength and connection stability. Perform a simple communication test to ensure data transmission is normal. Automatic configuration after connection establishment: The data acquisition and storage media automatically detects newly connected sensors. It initiates the sensor identification program, preparing to read the sensor's unique identification information. Handling special cases: If the selected interface cannot establish a connection, the system automatically tries other available interfaces. If all interfaces fail to establish a connection, the system provides an error message, suggesting checking for sensor or data acquisition and storage media malfunctions. Connection security considerations: For wireless connections, ensure appropriate encryption methods are used to protect data transmission security. For wired connections, consider using physical isolation or other security measures to prevent unauthorized access. Connection status monitoring: After connection establishment, continuously monitor the connection status. If the connection is interrupted, the system should be able to automatically reconnect or issue a warning. Through these steps, a flexible and reliable physical connection between the sensor and the data acquisition and storage media can be achieved. This design allows users to connect sensors to any interface of the data acquisition and storage media, greatly improving the system's usability and adaptability. Even if one interface fails, it can be easily switched to another interface, ensuring continuous system operation. This connection mechanism is particularly suitable for scenarios requiring frequent replacement or addition of different types of sensors, such as valve diagnostic systems.

[0043] In one specific embodiment, the process of performing step S3 may specifically include the following steps:

[0044] Select a target identification technology, which can be any of the following: 2D scanning identification technology, which scans the QR code label on the sensor using a scanning device on the acquisition storage medium; chip identification technology, which reads the information from the identification chip or storage circuit element integrated in the sensor signal connection plug or cable; communication verification and reading technology, which exchanges data with the sensor through a preset communication protocol to obtain the sensor's identification information; or RFID technology, which reads the information stored in the RFID code installed inside the sensor using an RFID reader.

[0045] The selected target recognition technology is used to scan or read the sensor in the initial connection state; the acquired scanning or reading results are parsed to extract the sensor's unique identification information; the extracted unique identification information is used as the sensor's identification information.

[0046] Specifically, select the target identification technology: Two-dimensional scanning identification technology: The data acquisition and storage medium is equipped with an integrated barcode scanner. A QR code tag containing its unique ID information is affixed to the sensor. The scanner can be a small camera or a dedicated QR code scanner. Chip identification technology: An identification chip or storage circuit element is integrated into the sensor's signal connection plug or cable. The data acquisition and storage medium is equipped with a corresponding chip reader. The identification chip can be an EEPROM, RFID chip, or other small storage device. Communication verification and reading technology: The data acquisition and storage medium is pre-set with various commonly used communication protocols. Data exchange with the sensor is performed by trying different protocols. Protocols may include, but are not limited to, industrial communication protocols such as Modbus, HART, and Profibus. RFID technology: An RFID tag is installed inside the sensor. The data acquisition and storage medium is equipped with an RFID reader. The sensor's ID information is stored in the offset code information of the RFID tag. Use the selected target identification technology to scan or read the sensor in the initial connected state: For two-dimensional scanning identification technology: Activate the barcode scanner on the data acquisition and storage medium. Scan the QR code tag on the sensor. Obtain the raw data of the scan result. For chip identification technology: Activate the chip reader on the acquisition storage medium. Establish a connection with the identification chip in the sensor connector plug or cable. Read the information stored in the chip. For communication verification reading technology: The acquisition storage medium attempts to communicate with the sensor using a preset communication protocol. Send a standard identification request command. Receive the data returned by the sensor. For RFID technology: Activate the RFID reader on the acquisition storage medium. Scan the RFID tag inside the sensor. Read the information stored in the RFID tag. Parse the acquired scan or reading results to extract the sensor's unique identification information: For QR code scan results: Use a QR code decoding algorithm to parse the scanned image data. Extract sensor ID and other related information from the decoded data. For chip reading results: Parse the raw data read from the chip according to a predefined data structure. Extract structured data containing sensor ID, model, calibration information, etc. For communication verification reading results: Parse the received data packets according to the communication protocol used. Extract the sensor's identification information from the data packets. For RFID reading results: Decode the data in the RFID tag. Extract the sensor's ID information from the decoded data. Use the extracted unique identification information as the sensor's identification information: Verify the completeness and validity of the extracted identification information. The verified identification information is temporarily stored in the memory of the data acquisition storage medium. This identification information is then prepared for subsequent sensor information calibration and data acquisition strategy generation. Error handling and exceptions: If the selected identification technology fails, the system automatically tries other available identification methods. If all identification methods fail, the system provides an error message, suggesting checking the integrity of the sensor identification or trying to manually input the identification information.Security considerations for identification information include: encrypting data transmitted during the identification process to prevent unauthorized interception; employing secure data storage methods to prevent unauthorized access; and utilizing this diverse and automated identification mechanism to quickly and accurately identify various types of sensors without manual intervention. This significantly improves system flexibility and efficiency, making it particularly suitable for scenarios requiring frequent replacement or addition of different sensor types, such as complex valve diagnostic systems. Furthermore, this approach facilitates future expansion with new sensor types; simply implementing a compatible identification method on the new sensor allows for easy integration into the existing system.

[0047] In one specific embodiment, the process of performing step S4 may specifically include the following steps:

[0048] Based on the identification information, sensor-related information is retrieved from a preset database to obtain the sensor's functional attributes, calibration information, and corresponding algorithms.

[0049] Develop a data acquisition plan based on the acquisition strategy, including: setting the acquisition items and sequence for valve operation physical change data; determining the trigger and termination conditions for data acquisition; and configuring the data storage format and storage period.

[0050] The data acquisition plan is sent to the acquisition and storage medium to guide the acquisition and storage medium to collect physical change data of valve operation through sensors;

[0052] Specifically, sensor-related information is retrieved from a pre-set database based on the identification information: A pre-set database containing information on various sensors is established and maintained. The unique identification information obtained in step S3 is used as the search keyword. The following information is retrieved from the database: sensor functional attributes (such as measurement range, response time, etc.); calibration information (such as calibration date, calibration coefficient, etc.); and the corresponding data processing algorithm. An acquisition strategy is generated based on the functional attributes, calibration information, and corresponding algorithm: The sensor's acquisition signal type and accuracy are determined: Based on the sensor's functional attributes, the signal type (such as analog quantity, digital quantity, etc.) is determined; an appropriate acquisition accuracy (such as 16-bit, 24-bit, etc.) is set.

The acquisition storage medium receives and parses the instruction set, preparing to execute the data acquisition task. Configure the data storage module of the acquisition storage medium: Configure the parameters of the storage module according to the storage requirements in the data acquisition plan. Set the data storage path, file naming rules, etc. Configure data backup and synchronization mechanisms to ensure data security. Data acquisition and storage: Based on the configured acquisition strategy, physical change data of valve operation are collected via sensors.
