[0001] The present invention relates to the technical field of road maintenance machinery safety monitoring, and in particular to a WD-320 stabilizing vehicle safety early warning system. Background Art

[0002] During the operation of the front cab, the temperature and pressure of the hydraulic mechanical torque converter and the engine cannot be observed. When operating at high power for a long time, the high temperature and high pressure will cause damage to the hydraulic mechanical torque converter and the engine, affecting the safety of train operation and causing property losses. When the driver is operating at the switching operation end, if he cannot observe the temperature and pressure of the engine and ZF hydraulic torque converter in time, especially when operating on a long slope, the temperature of the engine and ZF hydraulic torque converter will rise, which will cause damage to the internal structure of the engine and ZF hydraulic torque converter, resulting in the need to repair or replace the engine and ZF hydraulic torque converter, increasing cost waste. When the driver is operating large-scale road maintenance machinery, the pressure and temperature of the engine and ZF hydraulic torque converter cannot be observed in time, and the equipment is in a bad state, which will directly affect the operating efficiency and operation efficiency of the equipment.

[0003] Therefore, it is an urgent problem to design a WD-320 stable vehicle safety warning system, which can fully ensure the timely monitoring of the hydraulic mechanical torque converter and the engine and realize the efficient operation and operation of the equipment by providing the status display of the hydraulic mechanical torque converter and the engine in different areas of the locomotive. Summary of the invention

[0004] The purpose of the present invention is to provide a WD-320 stable vehicle safety warning system, which fully ensures timely monitoring of the hydraulic mechanical torque converter and the engine and realizes efficient operation and operation of the equipment by providing status displays of the hydraulic mechanical torque converter and the engine in different areas.

[0005] In a first aspect, the present invention provides a WD-320 stable vehicle safety warning system, comprising: a pressure monitoring component, a temperature monitoring component, an information display unit, a position display switching component and a warning analysis module; the pressure monitoring component is used to measure the real-time pressure information of the target vehicle; the temperature monitoring component is used to measure the real-time temperature information of the target vehicle; the information display unit is respectively connected to the pressure monitoring component and the temperature monitoring component to obtain the real-time pressure information collected by the pressure monitoring component and the real-time temperature information collected by the temperature monitoring component, and there are two information display units, which are respectively located in different areas of the target vehicle; the position display switching component is respectively connected to the two information display units to select and display the two information display units; the warning analysis module is connected to the information display unit to obtain the collected real-time temperature information and real-time pressure information from the information display unit, and perform operation safety warning analysis to form operation safety warning analysis result data.

[0006] In the present invention, the method provides status displays of the hydromechanical torque converter and the engine in different areas, thereby fully ensuring timely monitoring thereof and achieving efficient operation and operation of the equipment.

[0007] As a possible implementation manner, the two information display units are respectively located in the operating end area and the non-operating end area of ​​the target vehicle.

[0008] In the present invention, the non-operating area and the operating area are areas where operators are often present, so the displays provided in the two areas basically cover the location of the operators when the locomotive is in use.

[0009] As a possible implementation manner, the information display unit includes a display.

[0010] In the present invention, the display can display information about the fault situation, which is intuitive and convenient.

[0011] As a possible implementation manner, the information display unit also includes a buzzer.

[0012] In the present invention, the buzzer can be used to remind the operator when he is not on duty, and multiple forms of early warning can be used to improve the effect of early warning.

[0013] As a possible implementation manner, the information display unit also includes a warning light.

[0014] In the present invention, the warning light can be used to remind the operator when he is not on duty, and multiple forms of warning can be used to improve the effect of the warning.

[0015] As a possible implementation method, the early warning analysis module implements the operation safety early warning analysis in the following ways: obtaining the real-time operating temperature G of the engine tem 、Engine real-time operating pressure G pre , Torque converter real-time operating temperature T tem And the torque converter real-time operating pressure T pre ; Set the effective analysis time and determine the real-time operating temperature of the engine within the effective analysis time G tem The real-time engine operating temperature curve formed, the real-time engine operating pressure G within the effective analysis time pre The real-time operating pressure curve of the engine and the real-time operating temperature T of the torque converter within the effective analysis time are formed. tem The real-time operating temperature curve of the torque converter formed, the real-time operating pressure T of the torque converter within the effective analysis time preThe real-time operating pressure curve of the torque converter is formed; the normal threshold value of engine temperature, the normal threshold value of engine pressure, the normal threshold value of torque converter temperature and the normal threshold value of torque converter pressure are set, and according to the real-time operating temperature curve of the engine, the real-time operating pressure curve of the engine, the real-time operating temperature curve of the torque converter and the real-time operating pressure curve of the torque converter, an operation safety early warning analysis is performed to form the operation safety early warning analysis result data.

[0016] In the present invention, of course, the operating status monitoring of the engine and the torque converter can be simply analyzed and processed to provide information prompts of abnormal status.

[0017] As a possible implementation method, a normal engine temperature threshold, a normal engine pressure threshold, a normal torque converter temperature threshold, and a normal torque converter pressure threshold are set, and an operation safety early warning analysis is performed according to the engine real-time operating temperature curve, the engine real-time operating pressure curve, the torque converter real-time operating temperature curve, and the torque converter real-time operating pressure curve to form operation safety early warning analysis result data, including: if there is a time period of the engine real-time operating temperature G for a period of time as long as the effective duration on the engine real-time operating temperature curve tem If the engine temperature exceeds the normal threshold, and the engine real-time operating pressure curve, the torque converter real-time operating temperature curve and the torque converter real-time operating pressure curve all have an upward trend in the corresponding time period, an engine temperature overtemperature warning message is generated; if there is a period of time on the engine real-time operating temperature curve that lasts as long as the effective duration, the engine real-time operating temperature G tem If the engine temperature exceeds the normal threshold, and the engine real-time operating pressure curve, the torque converter real-time operating temperature curve, and the torque converter real-time operating pressure curve do not all show an upward trend within the corresponding time period, an operation monitoring fault information is generated.

[0018] In the present invention, it is understandable that when the temperature of the engine changes, the engine pressure, the temperature and pressure of the torque converter will change accordingly. Only by obtaining these changes can it be determined that the temperature abnormality signal truly reflects the abnormal loading of the engine.

[0019] As a possible implementation method, a normal engine temperature threshold, a normal engine pressure threshold, a normal torque converter temperature threshold, and a normal torque converter pressure threshold are set, and an operation safety early warning analysis is performed according to the engine real-time operation temperature curve, the engine real-time operation pressure curve, the torque converter real-time operation temperature curve, and the torque converter real-time operation pressure curve to form operation safety early warning analysis result data, including: if there is a time period of effective duration on the engine real-time operation temperature curve, the engine real-time operation pressure G preIf the engine pressure exceeds the normal threshold, and the engine real-time operating temperature curve, the torque converter real-time operating temperature curve and the torque converter real-time operating pressure curve all have an upward trend in the corresponding time period, an engine pressure overtemperature warning message is generated; if there is a period of effective duration on the engine real-time operating temperature curve, the engine real-time operating pressure G pre If the engine pressure exceeds the normal threshold, and the engine real-time operating temperature curve, the torque converter real-time operating temperature curve and the torque converter real-time operating pressure curve do not all show an upward trend within the corresponding time period, an operation monitoring fault information is generated.

[0020] In the present invention, similarly, when the engine pressure changes, the engine temperature, the torque converter temperature and the pressure will change accordingly. Only by obtaining these changes can it be determined that the pressure abnormality signal truly reflects the abnormal loading of the engine.

[0021] As a possible implementation method, a normal engine temperature threshold, a normal engine pressure threshold, a normal torque converter temperature threshold, and a normal torque converter pressure threshold are set, and an operation safety early warning analysis is performed according to the engine real-time operating temperature curve, the engine real-time operating pressure curve, the torque converter real-time operating temperature curve, and the torque converter real-time operating pressure curve to form operation safety early warning analysis result data, including: if there is a time period of effective duration on the torque converter real-time operating temperature curve, the torque converter real-time operating temperature T tem If the torque converter temperature exceeds the normal threshold, and the engine real-time operating temperature curve, the engine real-time operating pressure curve and the torque converter real-time operating pressure curve all have an upward trend in the corresponding time period, a torque converter temperature overtemperature warning message is generated; if there is a time period of effective duration on the torque converter real-time operating temperature curve, the torque converter real-time operating temperature T tem If the temperature of the torque converter exceeds the normal threshold, and the real-time operating temperature curve of the engine, the real-time operating pressure curve of the engine, and the real-time operating pressure curve of the torque converter do not all show an upward trend within the corresponding time period, an operation monitoring fault information is generated.

[0022] In the present invention, similarly, when the temperature of the torque converter changes, the temperature of the engine, the pressure of the engine and the pressure of the torque converter will change accordingly. Only by obtaining these changes can it be determined that the temperature abnormality signal truly reflects the abnormal loading of the torque converter.

[0023] As a possible implementation method, a normal engine temperature threshold, a normal engine pressure threshold, a normal torque converter temperature threshold, and a normal torque converter pressure threshold are set, and an operation safety early warning analysis is performed according to the engine real-time operating temperature curve, the engine real-time operating pressure curve, the torque converter real-time operating temperature curve, and the torque converter real-time operating pressure curve to form operation safety early warning analysis result data, including: if there is a time period of effective duration on the torque converter real-time operating pressure curve, the torque converter real-time operating pressure T pre If the torque converter pressure exceeds the normal threshold, and the engine real-time operating temperature curve, the engine real-time operating pressure curve and the torque converter real-time operating temperature curve all have an upward trend in the corresponding time period, a torque converter pressure overtemperature warning message is generated; if the torque converter real-time operating pressure curve has a time period as long as the effective duration, the torque converter real-time operating pressure T pre If the torque converter pressure exceeds the normal threshold, and the engine real-time operating temperature curve, the engine real-time operating pressure curve, and the torque converter real-time operating temperature curve do not all show an upward trend within the corresponding time period, an operation monitoring fault information is generated.
