Description

Technical Field

[0001] This invention relates to the field of vehicle safety monitoring technology, and in particular to a real-time monitoring device for tire temperature and pressure of heavy vehicles. Background Technology

[0002] With the development of mining and large-scale engineering construction, the application of special heavy-duty vehicles such as wide-body mining trucks and heavy-duty engineering dump trucks continues to expand. These vehicles are characterized by their extremely high weight, high single-vehicle load capacity, high work intensity, and long continuous operating time. They are also used for long-term operation on unpaved roads in mining areas with dense gravel, potholes, high dust levels, and extreme temperature differences.

[0003] Heavy-duty tires are subjected to continuous high loads, repeated deformations, and intense friction during operation, which makes them prone to abnormal tire pressure and rapid increases in tire temperature. These are the main causes of tire blowouts and vehicle rollovers due to loss of control. This not only results in the scrapping of expensive tires and vehicle downtime, but may also lead to major safety accidents.

[0004] Currently, the most similar existing solution in the industry is the universal vehicle TPMS (Tire Pressure Monitoring System). The mainstream implementation involves installing pressure and temperature sensors inside the tire or at the valve stem, transmitting the data wirelessly to a display terminal in the driver's cab, and setting fixed threshold values ​​for audible and visual alarms when these values ​​exceed limits. A few manufacturers have made simple reinforcements to the universal TPMS for heavy-duty freight vehicles, improving its pressure and shock resistance while retaining basic functions such as high / low pressure alarms and high temperature alarms.

[0005] However, the aforementioned existing technologies still have the following drawbacks: Poor adaptability to extreme working conditions: General-purpose TPMS is designed for highway passenger cars and logistics trucks, and does not take into account the heavy-duty, strong vibration, strong dust and large temperature difference working conditions in mining. The sensor is prone to temperature drift and pressure drift, resulting in data distortion, false alarms and missed alarms. Poor structural durability: Insufficient protection level and impact resistance. Impact from crushed rocks, mud and water corrosion, and high-frequency vibration in the mining area can easily cause the sensor to loosen, fall off, or get wet, resulting in short lifespan and high maintenance costs. Unstable signal transmission: Large electromechanical equipment in the mining area is subject to strong electromagnetic interference, traditional wireless radio frequency is easily shielded, data packet loss, delay, and disconnection make it difficult to monitor in real time throughout the entire process. The early warning logic is rudimentary: it only uses a fixed threshold for passive over-limit alarm, and cannot make dynamic judgments based on load, operating conditions, and ambient temperature, making it difficult to predict hidden dangers such as chronic leaks and slow temperature rises. Poor overall economic efficiency: lack of tire health range guidance, abnormal tire wear, premature aging, short service life, and high procurement and downtime costs.

[0006] Therefore, it is necessary to provide a new real-time tire temperature and pressure monitoring device for heavy vehicles to solve the above-mentioned technical problems. Summary of the Invention

[0007] The technical problem solved by this invention is to provide a real-time monitoring device for tire temperature and pressure of heavy vehicles that can achieve accurate real-time monitoring of heavy-duty tires, has a robust and durable structure, can provide early warning, and improve safety in mining areas.

[0008] To solve the above-mentioned technical problems, the heavy vehicle tire temperature and pressure real-time monitoring device provided by the present invention includes: a tire-end high-precision sensing and acquisition module, an anti-interference wireless transmission module, and a cab-mounted display and interaction terminal. The high-precision sensor acquisition module at the tire end is used to acquire tire parameters in real time. The anti-interference wireless transmission module is used to transmit the tire parameter information collected by the high-precision sensing acquisition module at the tire end to the in-vehicle display and interactive terminal in the driver's cab. The in-cab display and interactive terminal is used to display tire parameters and issue audible and visual alarms.

[0009] Preferably, the high-precision sensing and acquisition module at the tire end includes a connecting pipe, a protective sleeve, a frame, a sensor, and a protective cover. The sensor is connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the tire valve core. The protective sleeve is fixedly sleeved on the outside of the connecting pipe. The frame is fixedly mounted on the wheel hub of the tire. The protective cover is fixedly sleeved on the outside of the sensor, and the protective cover is fixedly connected to the frame.

[0010] Preferably, the tire parameters include one or more of tire temperature data, tire pressure data, and vibration data.

[0011] Preferably, it also includes an intelligent hierarchical early warning and dynamic processing control module, which is installed in the driver's cab vehicle display and interactive terminal, and is used to execute dynamic hierarchical early warning logic.

[0012] Preferably, the dynamic hierarchical early warning logic executed by the intelligent hierarchical early warning and dynamic processing control module includes: The safety warning threshold is dynamically and adaptively adjusted based on the vehicle's rated load, the ambient temperature of the mining area, the vehicle's continuous driving time, and the slope operation status. The system is designed with at least three levels of early warning mechanisms, including Level 1 for minor anomalies, Level 2 for serious over-limit alerts, and Level 3 for emergency audible and visual alarms. It can identify different types of faults, including rapid tire blowout, chronic minor air leakage, abnormal continuous temperature rise, and uneven tire pressure, and output different levels of alerts accordingly.

[0013] Preferably, it also includes an auxiliary operation and maintenance and data traceability module, which is used to retain the vehicle's tire temperature and tire pressure operation history for a long time, and automatically count the frequency of tire abnormalities and the duration of high temperature and high pressure operation.

[0014] Compared with related technologies, the real-time tire temperature and pressure monitoring device for heavy vehicles provided by this invention has the following advantages: This invention provides a real-time tire temperature and pressure monitoring device for heavy vehicles. Through a combination of a high-precision tire-end sensing module, an anti-interference wireless transmission module, and a cab-mounted display and interactive terminal, it enables accurate real-time acquisition and stable uploading of tire temperature, tire pressure, and vibration data under heavy-load conditions. The mechanical mounting structure, consisting of connecting pipes, protective sleeves, a frame, sensors, and a protective cover, prevents the sensors from loosening or falling off under strong vibration, gravel, and muddy conditions, significantly improving durability. The intelligent graded early warning and dynamic processing control module executes dynamic adaptive thresholds and three-level graded early warnings, which can identify latent faults such as chronic leaks and slow temperature increases in advance, effectively reducing the risk of sudden tire blowouts and rollovers. The auxiliary maintenance and data traceability module enables full-process data retention and statistical analysis, helping to extend tire lifespan, reduce procurement and downtime costs, and comprehensively improve the level of safety production management in mining areas.

The rear end of sensor 4 is connected to one end of connecting pipe 1, and the other end of connecting pipe 1 is connected to tire valve core 6 (which can be installed internally in the tire or externally via valve stem). A protective sleeve 2 is fixedly fitted on the outside of connecting pipe 1 to buffer against impact from gravel and erosion from mud and water. Frame 3 is fixed on tire hub 7 as a rigid mounting base.
