Features of the construction of an information system for assessing the parameters of the technical condition of vehicles in operating conditions

Abstract

In connection with the use of built-in on-board diagnostics on cars, the development of satellite navigation systems and mobile communications, modern information technologies, it became possible to carry out remote monitoring with an assessment of the level of technical condition of the vehicle. This, in turn, allows us to switch to an adaptive system of technical maintenance and repair of cars, the key point of which is the development of an information and communication system and information software systems that provide, by monitoring remotely, the technical parameters of a vehicle in operating conditions, and assess the technical parameters of vehicles in operation and development of corrective actions.

The purpose of the work is to generalize and develop existing modern information technologies in road transport in the conditions of intelligent transport systems (ITS).

It is shown that in the formation of the information software complex in the conditions of ITS, for the formalization of the main processes, the methodology of structural analysis and design of SADT was applied. The source data for monitoring the technical condition of the vehicle, in accordance with the provisions of the IDEF0 methodology, the design features of the vehicle and the particular operating conditions, there is information on the technical condition of the vehicle. In this case, the general software of the manufacturing enterprise for the operation of automobile transport has been supplemented with respect to the algorithms of the software when performing: vehicle identification; identification of operating conditions; checking the conformity of the vehicle condition to operating conditions.

To determine the subject area of ​​the information system for assessing the technical condition of a vehicle under operating conditions during its monitoring, a data flow diagram was used, which represents the highest descriptive level of a vehicle monitoring system.
