Figure 2 This is a module diagram of an automatic monitoring system for the driving safety of large transport vehicles based on long-distance transportation. Detailed Implementation

[0016] like Figure 1 As shown, Figure 1 This is a flowchart of an automatic monitoring method for the driving safety of large transport vehicles based on long-distance transportation, as proposed in this invention.

[0017] Reference Figure 1 The present invention proposes an automatic monitoring method for the driving safety of large transport vehicles based on long-distance transportation, comprising: During vehicle operation, the real-time tire pressures P1, P2...P of m tires are obtained. m ; Based on the P1, P2...P m Calculate the maximum pressure difference P0 and the average pressure P. ave ; , ; Compare the maximum differential pressure value P0 with the preset safe differential pressure value P0′. If P0 > P0′, compare P0′ with P0′. max With P ave P min With P ave Excessive pressure difference between the two tires of a long-haul large transport vehicle is a visible precursor to tire safety risks. It is often accompanied by uneven stress and abnormal conditions, and is directly related to safety risks such as tire blowouts, rollovers, and accelerated uneven wear. Using excessive pressure difference between the two tires of the same vehicle as the basis for subsequent risk verification helps to identify safety risks in advance and provides a safety control foundation for subsequent fault diagnosis. It is an indispensable core link in the tire safety management of long-haul large transport vehicles.

[0018] when At that time, record P max The system corresponds to the tire pressure change curve of the tire, and calculates the slope of the tire pressure change curve according to a preset time b. When the slope exceeds a preset safe slope threshold range, an alarm is triggered; when... At that time, record P minThe method records the tire pressure change curve corresponding to the tire, calculates the slope of the tire pressure change curve according to a preset time 'c', and activates an alarm when the slope exceeds a preset safe slope threshold. Here, 'a' is a preset value; 'b' and 'c' are also preset values, in seconds or minutes. This method can accurately adapt to the core scenarios of heavy-duty, long-distance, and complex operating conditions of large transport vehicles in long-distance transportation. Before tire blowouts or rapid damage occur in large vehicles, tire pressure often changes rapidly. For example, when a tire leaks air rapidly or overheats, the tire pressure slope may drop / rise rapidly. By quantifying the rate characteristics of tire pressure change, potential tire faults and hidden dangers can be detected in advance, enabling early warning and accurate alarms. This allows drivers sufficient time to decelerate and stop smoothly, avoiding serious accidents such as rollovers and rear-end collisions caused by tire blowouts at high speeds.

[0019] In a further embodiment, a preset safe high voltage value P is also provided. max Preset safe low pressure value P min ';when At that time, compare P max With respect to the preset safe high voltage value P max If P' max >P max ′, activate alarm; when At that time, compare P min With the preset safe low pressure value P min If P min <P min The system activates an alarm when the tire pressure of the target tire deviates significantly from the vehicle's average tire pressure. It employs a strategy comparing the highest and lowest tire pressures to anticipate any further deviations. This dual-judgment logic avoids the limitations of relying solely on a single out-of-average assessment method, improving the accuracy of safety hazard management, preventing misjudgments and omissions, helping drivers identify potential risks, and guiding them to take clear and effective action.

[0020] In a further embodiment, a preset tire pressure critical threshold range is also provided; when P max When the tire pressure exceeds the preset critical threshold range, obtain P. max The corresponding tire pressure rise rate f in the first d minutes r If f r The tire pressure rise rate f is higher than the preset safe tire pressure rate. r0 Activate alarm; when P min When the tire pressure exceeds the preset critical threshold range, obtain P. min The corresponding tire pressure drop rate f in the first e minutes f If f f Tire pressure below the preset safe level will result in a rate ff0 The alarm is activated; where d and e are preset values. The system determines the rate of increase / decrease in tire pressure within a preset time and triggers the alarm. It monitors potential tire risks through dynamic tire pressure trends, allowing for early fault identification, extended response time, and improved efficiency. Simultaneously, it filters temporary interference, reduces false alarm rates, and improves alarm accuracy.

[0021] In a further embodiment, a tire temperature abnormality monitoring mode is also provided, which is used to: when and / or At that time, obtain P max and P min The system tracks the real-time temperature change curve of the corresponding tires. When the temperature change rate exceeds the preset safe temperature change rate within a preset time, an alarm is triggered. Major accidents such as tire blowouts and fires on large vehicles often stem from the coupled risks of abnormal tire pressure and uncontrolled temperature. Introducing analysis of tire temperature and temperature change rate can help detect early warning signs of risk, while avoiding delayed alarms from single-parameter analysis, thus enabling precise prediction of tire safety management.

[0022] Reference Figure 2 , Figure 2 The present invention proposes an automatic monitoring system for the driving safety of large transport vehicles based on long-distance transportation, comprising: The tire pressure parameter acquisition unit is used to acquire the real-time tire pressure P1, P2...P of m tires during vehicle operation. m ; The pressure numerical calculation unit is used to calculate the pressure values ​​based on P1, P2...P m Calculate the maximum pressure difference P0 and the average pressure P. ave ; , ; The differential pressure information comparison unit is used to compare the maximum differential pressure value P0 with the preset safe differential pressure value P0′. If P0 > P0′, it compares P0 with P0′. max With P ave P min With P ave ; The comparison and analysis early warning unit is used when... At that time, record P max The system corresponds to the tire pressure change curve of the tire, and calculates the slope of the tire pressure change curve according to a preset time b. When the slope exceeds a preset safe slope threshold range, an alarm is triggered; when... At that time, record P minThe system corresponds to the tire pressure change curve and calculates the slope of the curve over a preset time interval (c). When the slope exceeds a preset safe slope threshold, an alarm is triggered. Here, 'a' is a preset value; 'b' and 'c' are also preset values, in seconds or minutes. Traditional static monitoring requires waiting for the tire pressure to deviate from the standard value by a certain range before triggering an alarm. By this time, the fault may have already progressed to an irreversible stage. However, calculating the slope through the tire pressure change curve allows for early detection of trends, triggering an alarm when the tire pressure has not reached a dangerous level but the rate of change is abnormal. This significantly reduces the incidence of tire-related accidents, and is particularly suitable for high-risk scenarios such as heavy-load driving and long-distance travel.

[0023] In a further embodiment, the comparison analysis and early warning unit is further provided with a preset safety high voltage value P. max Preset safe low pressure value P min ';when At that time, compare P max With respect to the preset safe high voltage value P max If P' max >P max ′, activate alarm; when At that time, compare P min With the preset safe low pressure value P min If P min <P min An alarm is triggered. Once the tire pressure of the target tire exceeds the average value, a progressive analysis is conducted by comparing the highest and lowest tire pressures. By constructing a dual analysis logic of absolute value judgment and relative difference verification (highest / lowest comparison), invalid warnings can be effectively filtered, faults accurately located, and transportation status optimized.

[0024] In a further embodiment, the comparison analysis and early warning unit is further provided with a preset tire pressure critical threshold range; when P max When the tire pressure exceeds the preset critical threshold range, obtain P. max The corresponding tire pressure rise rate f in the first d minutes r If f r The tire pressure rise rate f is higher than the preset safe tire pressure rate. r0 Activate alarm; when P min When the tire pressure exceeds the preset critical threshold range, obtain P. min The corresponding tire pressure drop rate f in the first e minutes f If f f Tire pressure below the preset safe level will result in a rate f f0An alarm is triggered; where d and e are preset values. After the target tire's pressure exceeds the average value, further analysis is performed to determine whether the actual tire pressure exceeds a preset critical threshold range. The rate of increase / decrease in tire pressure within a preset time is used to judge whether there is an abnormality in tire pressure changes and trigger an alarm. Through clear numerical boundary judgments, the direct safety risks caused by abnormal tire pressure are quickly identified, providing drivers and / or monitoring platforms with intuitive and operable safety warnings. This is suitable for real-world scenarios involving heavy loads, long distances, and complex operating conditions of large vehicles, providing early warnings of serious accidents such as tire blowouts and rollovers, and mitigating fatal risks.

[0025] In a further embodiment, the comparison analysis and early warning unit is further provided with a tire temperature abnormality monitoring mode, which is used to: when and / or At that time, obtain P max and P min The system tracks the real-time temperature change curve of the corresponding tire. When the temperature change rate exceeds the preset safe temperature change rate within a preset time period, an alarm is triggered. By introducing tire temperature analysis and temperature change rate alarms, and utilizing the physical linkage between temperature and tire pressure, temperature and temperature change rate are used as objective evidence to filter out invalid alarms, accurately verify the rationality of tire pressure changes, and significantly reduce the false alarm rate.

[0026] The present invention proposes an automatic monitoring device for the driving safety of large transport vehicles based on long-distance transportation, comprising: a memory and a processor. The memory is used to store information including program instructions, and the processor is used to control the execution of the program instructions. When the program instructions are loaded and executed by the processor, the automatic monitoring method for the driving safety of large transport vehicles based on long-distance transportation is realized.

[0027] The present invention proposes a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the aforementioned automatic monitoring method for the driving safety of large transport vehicles based on long-distance transportation.
