Improvement of the technology of diagnostics of electronic system of cars

Transport systems of cities and regions are the most important element in shaping the environment for the life of society. Social functioning at the present time, in an era of rapid scientific progress and economic development is impossible without efficient infrastructure. Certainly in as part of the formation of a favorable environment for the life of society, trends in improvement of the infrastructure itself and its elements should be at a high and dynamic level. Particular attention should be paid to the element life support, which affects both social performance and social tension. Thus, one of the most significant elements infrastructure -transport. Transport infrastructure is understood as a set of all sectors and enterprises of transport that carry out transportation of various appointments and ensuring their implementation and maintenance. Functioning transport is impossible without a transport system. In the concept of transport systems include such components as vehicles, conditions for their provision, transport controls. The most acute in the territory of the Russian Federation the question of the existence and condition of communication lines has always been raised. In view of the big and, to In addition, an unevenly developed and developed territory has difficulties with using existing communications. For timely assessment and forecasting of the state of the object, it is necessary solution of the following tasks:

• - determination of the state in which the object was originally upon delivery to operation (assuming the normative state);

• - determination of the actual technical condition;

• - determination of the state in which the object will be after a certain time interval.

Accordingly, in order to implement the task of timely assessment, it is necessary solution of the three-level system. The task of the first level refers to the technical genetics (the history of the creation and operation of the object), the task of the second level is to technical diagnostics; the third - to forecasting. The establishment of actual damage, their signs and volumes, is engaged in technical diagnostics. It is based on methods for assessing the quality and condition individual elements of roads and the entire structure as a whole. Diagnostic process includes:

• - visual determination of the degree of deterioration of the structure by external signs;

• - instrumental assessment of the state of the structure using

• - specialized measuring instruments;

• - expert analysis of the results of field work.
