Example Embodiment

[0032] Embodiment: After the monitoring module collects that the engine oil pressure value is lower than the normal value, it immediately sends a low oil pressure alarm message from the bus. After the monitoring module receives the information, it judges whether it is a false alarm through the false alarm processing program. After the judgment result is true, transfer to the analysis control module. The analysis control module queries from the database. After determining that it is a first-level fault, the information and the alarm level are transferred to the first-level alarm preset program and sent to the alarm module. The alarm module drives The alarm and the red alarm light will beep for a long time, and the text message of low oil pressure will be displayed on the display screen. After the driver responds or the fault signal disappears, the monitoring system will turn off the sound and light alarm device. Before the fault is eliminated, the screen will keep the alarm promp...

Abstract

The invention discloses a vehicle condition monitoring device, which specifically relates to a method for multi-mode alarm of a special vehicle. The monitoring device comprises a measuring module, a monitoring module and an alarm module, wherein the monitoring module includes an analysis control module and a data base. The data base includes all normal information of each part of the vehicle and different classified alarm information divided according to malfunction degree of each part. The method classifies all alarm information according to vehicle system state and influence on the overall vehicle displayed by the alarm information, and adopts different manners to warn drivers to pay attention through classified arrangement and damage evaluation of different alarms. After a new alarm comes, a system can still continue alarming, thereby realizing actively warning the drivers and avoiding larger malfunctions. Moreover, as the alarm system is adopted to monitor the vehicle state, the drivers can focus on driving, which reduces labor intensity and improves man-machine operation.

Description

technical field [0001] The invention relates to a vehicle state monitoring system, in particular to a multi-mode alarm method for special vehicles. Background technique [0002] At present, the alarm device used in vehicles can activate the alarm horn as long as it is important alarm information. When the noise needs to be silenced, it is manually cut off. The subsequent new alarm cannot activate the horn again, and some general faults are only displayed through icons. Difficult, if left untreated for a long time, it may cause a bigger failure. [0003] In special vehicles, due to its complex tasks and various functional systems, with the continuous improvement of the level of informatization, the driver needs to monitor more and more parameters, resulting in a surge in the amount of information the driver needs to receive. , The driver cannot quickly judge the warning information issued by some systems, and sometimes cannot find the fault in time, resulting in delays in ta...
