Figure 2 This is a top view of the locomotive sensor measurement and control device provided in the embodiment of this application after assembly and connection. Figure 3This is a schematic diagram of the internal structure of the locomotive sensor measurement and control device provided in this application embodiment. The locomotive sensor measurement and control device includes: a housing 1000; a temperature acquisition element measurement and control device 1001, a locomotive temperature gauge interface 1002, an external sensor interface 1003, and a locomotive temperature sensor interface 1004 disposed on the housing 1000; and a temperature transmitter 1005 and a precision resistor assembly 1006 disposed inside the housing 1000. The housing 1000 serves as the mounting base and protective structure for the device. The external surface of the housing 1000 is equipped with the temperature acquisition element measurement and control device 1001, the locomotive temperature gauge interface 1002, the external sensor interface 1003, and the locomotive temperature sensor interface 1004. These externally configured components are electrically connected to the temperature transmitter 1005 and the precision resistor assembly 1006 disposed inside the housing 1000 via internal wiring. The locomotive temperature gauge interface 1002 has one end connected to the existing locomotive temperature gauge 4000, and the other end connected to the precision resistor assembly 1006 inside the housing 1000. The external sensor interface 1003 has one end connected to the magnetic temperature sensor 2000, and the other end directly connected to the temperature acquisition element control device 1001 on the housing 1000. The locomotive temperature sensor interface 1004 has one end connected to the existing locomotive temperature sensor 4001, and the other end connected to the temperature transmitter 1005 inside the housing 1000. The temperature transmitter 1005, as a signal processing component, has its input end connected to the locomotive temperature sensor interface 1004 to receive the signal from the locomotive temperature sensor 4001, and its output end connected to the temperature acquisition element control device 1001 to transmit the processed signal to the control device. The precision resistor assembly 1006 serves as a signal analog and feedback component. Its indicating end connects to the locomotive temperature gauge interface 1002 to provide analog signals to the locomotive temperature gauge 4000, while its control end connects to the temperature acquisition element control device 1001 to receive control commands from the control device. By integrating multiple interfaces on the housing 1000, it can simultaneously connect to the locomotive's existing temperature gauge, the locomotive's existing temperature sensor, and the external magnetic temperature sensor 2000, enabling the device to have comprehensive control capabilities for both the locomotive's existing temperature monitoring system and external sensors, thus improving the device's compatibility and applicability. The temperature transmitter 1005 accurately processes the signals transmitted from the locomotive temperature sensor 4001, ensuring the accuracy and reliability of the signals received by the temperature acquisition element control device 1001. The precision resistor assembly 1006, under the control of the temperature acquisition element control device 1001, provides a stable analog signal to the locomotive temperature gauge 4000, facilitating the verification of the locomotive temperature gauge 4000's operating status. The combination of these two components enhances the accuracy of temperature monitoring and verification.The magnetic temperature sensor 2000 connects to the device via an external sensor interface 1003. Its magnetic design facilitates quick installation and relocation in different locations on the locomotive, enhancing the device's flexibility in various monitoring scenarios. The entire device is integrated within the housing 1000, featuring a compact and rationally laid-out structure that adapts to the limited installation space inside the locomotive. The housing 1000 also effectively protects internal components, reducing the impact of vibrations and dust during locomotive operation, thus improving the device's durability and operational stability. The temperature acquisition element monitoring and control device 1001 centrally processes and analyzes signals from each interface, enabling real-time monitoring, comparison, and verification of the locomotive's temperature status. This provides reliable data support for the maintenance and troubleshooting of the locomotive's temperature system, helping to promptly detect anomalies in the temperature monitoring process and ensuring the safe operation of the locomotive.

[0037] In some embodiments of this application, the temperature acquisition element measurement and control device 1001 includes an industrial computer and a computer mounting bracket. The computer mounting bracket is fixed to a preset position on the inner wall of the housing 1000 by bolts or other connectors. The industrial computer is stably installed through slots or fastening structures on the mounting bracket, ensuring a firm connection with the housing 1000. The industrial computer is used to configure the laboratory virtual instrument engineering platform program software, specifically the Laboratory Virtual Instrument Engineering Workbench, or LabVIEW program software for short. LabVIEW is a graphical programming language that uses icons instead of text lines to create applications. LabVIEW uses a dataflow programming approach, where the data flow between nodes in the block diagram determines the program's execution order. It uses icons to represent functions and lines to represent data flow. Temperature display and control are achieved using LabVIEW program software. This technology eliminates distributed circuitry compared to previous technologies, offering advantages such as fewer circuits, higher flexibility, stronger scalability, and reusability, making it more suitable for the rapid development of measurement and control technology in today's field.

[0038] The temperature acquisition element measurement and control device 1001 is equipped with LabVIEW software on its industrial computer. The two work together to form an integrated temperature acquisition element measurement and control system, which is the core control and data processing module of the entire device. The LabVIEW software uses graphical programming to achieve centralized control of various components inside and outside the enclosure 1000, including data interaction with the temperature transmitter 1005, precision resistor assembly 1006, external sensor interface 1003, locomotive temperature sensor interface 1004, and locomotive temperature gauge interface 1002.

[0039] In some embodiments of this application, the enclosure 1000 serves as the basic structure of the device. Externally, it houses a temperature acquisition and control device 1001, a locomotive temperature gauge interface 1002, an external sensor interface 1003, and a locomotive temperature sensor interface 1004. Internally, it contains a temperature transmitter 1005, a precision resistor assembly 1006, and a battery 1007. The battery 1007 is installed in an adapter position within the enclosure 1000 and is electrically connected to the temperature acquisition and control device 1001, the temperature transmitter 1005, and the precision resistor assembly 1006 via wires, providing stable power support to each component.

[0040] The installation of battery 1007 frees the device from dependence on external power sources of the locomotive, enabling it to maintain normal operation even when the locomotive loses power or the power supply fails. This enhances the device's independence and emergency response capabilities, and ensures the continuity of temperature monitoring.

[0041] The industrial computer is stably installed using a computer mounting bracket, which effectively mitigates the impact of vibrations during locomotive operation on the industrial computer, avoids component loosening or data transmission interruption caused by shaking, ensures long-term stable operation of the industrial computer, and guarantees the reliability of data processing and analysis.

[0042] In some embodiments of this application, the surface of the housing 1000 is also provided with a charging port 1008, a power indicator light 1009, and a power switch 1010. These three are usually arranged in a convenient area on the side or front of the housing 1000. The charging port 1008 is connected to the battery 1007 via internal wiring and is used to connect an external power source to replenish the battery 1007. The power switch 1010 is connected in series in the main circuit of the device and is used to control the power supply of the entire device. The power indicator light 1009 is connected in parallel with the main circuit and visually indicates whether the device is powered on by the illumination of the light.

[0043] The configuration of charging port 1008, power indicator light 1009 and power switch 1010 makes the charging operation of battery 1007 convenient and efficient. At the same time, it allows operators to intuitively judge the power supply status of the device. The power switch 1010 can quickly control the start and stop of the device, simplifying the operation process, reducing the difficulty of use, and facilitating daily maintenance and management.

[0044] In some embodiments of this application, the external sensor interface 1003 adopts a magnetic interface design, the structure of which matches the matching magnetic temperature sensor 2000, enabling rapid adsorption connection. The magnetic temperature sensor 2000 is encased in a protective housing made of high-temperature resistant and impact-resistant material. The temperature sensing element is fixed in the middle of the protective housing, avoiding direct contact with external hard objects while accurately sensing the temperature of the location to be measured. The sensor can stably adhere to various surfaces of the locomotive to be measured using its own strong magnetic component.

[0045] The external sensor interface 1003 adopts a magnetic design and is paired with a magnetic temperature sensor 2000. This eliminates the need for cumbersome plugging and unplugging when connecting the sensor to the interface; simply bringing the sensor close together is sufficient for docking. Simultaneously, the sensor can be quickly and magnetically fixed to different measurement locations on the locomotive without additional tools, significantly improving installation and replacement efficiency and enhancing the device's adaptability to diverse monitoring scenarios. The protective shell of the magnetic temperature sensor 2000 effectively protects against dust, oil, vibration, and minor impacts in the locomotive's operating environment, preventing sensor damage. The temperature sensing element is located in the center of the protective shell, avoiding temperature interference from the outer shell while ensuring accurate contact with the measured surface, guaranteeing the accuracy of temperature measurement and extending the sensor's lifespan.

[0046] In some embodiments of this application, the instrument mounting device 3000 consists of a locomotive temperature gauge 4000 mounting bracket and a signal access device wiring board. The locomotive temperature gauge 4000 mounting bracket is equipped with a rotating shaft with an angle scale. The rotating shaft is connected to the bracket body by locking bolts. Loosening the bolts can adjust the angle of the rotating shaft, and locking them can fix the angle. The bracket is installed in a suitable position on the housing 1000 or locomotive by fixing screws. It is also equipped with a terminal block for standardizing the wiring of the temperature gauge. The signal access device wiring board is installed next to the bracket for centralized management of the access and conversion of various signal lines.

[0047] The rotating shaft with angular scale allows the installation angle of the locomotive temperature gauge 4000 to be precisely adjusted according to observation needs, and the locking bolts ensure that the angle will not loosen after it is fixed; the terminal block and the signal access device wiring board standardize the wiring connection, avoiding poor contact or difficulty in troubleshooting caused by messy wiring, and improving the flexibility of temperature gauge installation and the convenience of wiring maintenance.

[0048] In some embodiments of this application, the locomotive temperature sensor interface 1004 has broad compatibility and can be adapted to any of the two-wire, three-wire, and four-wire resistance temperature sensor leads used in railway diesel locomotives. The interface is surrounded by a protective shell made of insulating and wear-resistant material, which tightly wraps the interface and surrounding connection parts.

[0049] The 1004 locomotive temperature sensor interface is compatible with various wire types of resistance temperature sensors, eliminating the need to change the interface due to different sensor types. This expands the applicability of the device and reduces equipment adaptation costs. The outer protective shell effectively isolates the interface from external moisture, dust, and mechanical wear, extending the interface's service life and ensuring connection stability.

[0050] In some embodiments of this application, all wires connected to the temperature acquisition element control device 1001 are sheathed flexible shielded wires. The sheath is made of a material with excellent insulation properties and has an internal metal shielding layer. Both ends of the wires are securely connected to the interfaces of various components through dedicated connectors to ensure the stability of signal and power transmission. The use of sheathed flexible shielded wires provides good insulation protection through the sheath, preventing short circuits or leakage. Furthermore, the shielding layer significantly reduces interference from the complex electromagnetic environment inside the locomotive on signal transmission, ensuring accurate transmission of temperature data and control signals. The flexible nature of the wires makes wiring within the housing 1000 more flexible, adaptable to the installation positions of different components, and reduces wiring difficulty.

[0051] Specifically, when the locomotive temperature sensor 4001 is being tested, its leads are connected to the locomotive temperature sensor interface 1004. The output electrical signal, such as the resistance change of the PT100 thermal resistor, is converted into an analog voltage signal by the temperature transmitter 1005 and transmitted to the temperature acquisition element control device 1001. The LabVIEW software receives this analog signal, converts it into a digital temperature value through the analog-to-digital converter of the industrial computer, and displays it in real-time on the interface in both numerical and graphical formats.

[0052] The LabVIEW software includes a built-in parameter library for the 4001 two-wire, three-wire, and four-wire RTD temperature sensors and the 4000 locomotive temperature gauge, commonly used in railway diesel locomotives. This library covers the signal characteristics, temperature-resistance relationships, and error correction parameters for different models. When users operate the "Temperature Gauge Selection" and "Temperature Sensor Selection" functions via the industrial computer's touchscreen, the software automatically calls matching signal processing algorithms, such as the lead compensation algorithm for three-wire RTDs, to ensure data processing accuracy.

[0053] Users can set the upper and lower temperature limits using the LabVIEW software. The software compares the measured temperature value with the set value in real time: if the temperature is within the normal range, the power indicator 1009 will show green; if it is greater than the upper temperature limit, the power indicator 1009 will show red; if it is less than the lower temperature limit, the power indicator 1009 will show yellow, providing intuitive feedback on the temperature status.

[0054] The magnetic temperature sensor 2000 connected to the external sensor interface 1003 and the locomotive temperature sensor 4001 simultaneously measure the same temperature point, and both data are transmitted to the temperature acquisition element control device 1001. The LabVIEW program software compares the two sets of data in real time, calculates the deviation value = locomotive temperature sensor reading - sensor reading, and displays it in tabular form, providing a quantitative basis for evaluating the accuracy of the locomotive temperature sensor 4001.

[0055] When testing the locomotive temperature gauge 4000 alone, the LabVIEW software sends commands to the precision resistor assembly 1006 via the control terminal, driving it to output a resistance value at a specific temperature point, such as 100Ω for 0℃ and 138.5Ω for 100℃. This resistance value is transmitted to the locomotive temperature gauge 4000 via the locomotive temperature gauge interface 1002. The LabVIEW software simultaneously displays the theoretical temperature value corresponding to the resistance value and the displayed value of the locomotive temperature gauge 4000 on the interface, allowing the user to perform calibration and adjustment by comparison.

[0056] A locomotive includes the aforementioned locomotive sensor monitoring and control device, as well as the locomotive temperature gauge 4000 and the locomotive temperature sensor 4001. The locomotive sensor monitoring and control device is integrated into the locomotive system and works in conjunction with the locomotive's existing locomotive temperature gauge 4000 and locomotive temperature sensor 4001. Electrical connection and data exchange are achieved through corresponding interfaces to form a complete locomotive temperature monitoring and control system.

[0057] After integrating the device into the locomotive system, it can seamlessly cooperate with the locomotive's existing temperature monitoring components. It retains the original temperature monitoring function while also verifying and enhancing the existing system through external sensors and internal measurement and control components, improving the overall accuracy and reliability of locomotive temperature monitoring and providing more comprehensive data support for the safe operation of the locomotive. Before use, check the battery level (1007) and confirm normal power supply via the power indicator light (1009). If the battery is low, charge it promptly through the charging port (1008). When connecting the interfaces, ensure accurate alignment. For magnetic interfaces, ensure secure adhesion, and check for loose connections. When installing the magnetic temperature sensor (2000), choose a flat surface on the locomotive to ensure tight contact between the sensor and the surface being measured, avoiding air gaps that could affect measurement accuracy. After adjusting the locomotive temperature gauge (4000) angle, tighten the locking bolts to prevent angle deviation during operation. Regularly check the connections of each component and the integrity of the protective casing. If any damage to the wire sheath or cracks in the interface protective casing are found, replace them in time to ensure the safe and stable operation of the device.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
