Abstract

The invention discloses a vehicle distributed multilevel health state monitoring system, relating to the vehicle vehicle-mounted health state monitoring technology and aiming to solve problems of poor flexibility and universality and a low utilization rate of monitoring data in the current vehicle monitoring system. In the vehicle distributed multilevel health state monitoring system, a plurality of collection nodes respectively collect measurement information transmitted by a plurality of sensors; the measurement information is transmitted to a plurality of convergence nodes; the convergence nodes transmit the measurement information transmitted by the plurality of collection nodes to a comprehensive information aggregation device after aggregation; the comprehensive information aggregation device receives measurement information transmitted by the plurality convergence nodes and state information of various vehicle-mounted devices and transmit the measurement information and the vehicle-mounted state information to a health information processing device after aggregation; and the health information processing device processes, stores and displays the received information. The vehicle distributed multilevel health state monitoring system is good in flexibility and universality, can deeply dig and analyze the monitoring data and is applicable to various vehicles.

Description

technical field [0001] The invention relates to vehicle health state monitoring technology. Background technique [0002] There are various types of vehicles, more and more functions, and more and more complex structures. Many vehicles work in harsh environments and are usually in high-load working conditions. Therefore, under long-term operating conditions, the mechanical reliability and performance of the vehicle will gradually decrease, and the probability of failure will increase. In order to reduce the occurrence of failures and accidents, improve the reliability, safety and maintenance efficiency of vehicle operation at the same time, and ensure that the fault location can be quickly diagnosed when a failure occurs, it is necessary to monitor the important operating state parameters of the vehicle, such as engine vibration, hydraulic oil, etc. Carry out real-time monitoring of quality and tire pressure. [0003] Because various vehicles are not only different in size...
