Description

Technical field

The proposed utility model relates to the field of passenger vehicles and can be used to provide high-quality and safe road services that meet modern quality standards for passenger transportation.

State of the art

From the prior art, a data acquisition control system based on signal processing in vehicles is known (see RU2737665, class H04L29/08, publ. 02.12.2020 [1]).

The known data acquisition system [1] refers to a technology for dynamic control of data acquisition based on sensors in vehicles, taking into account dynamic signal control and signal processing parameters based on continuously changing data parameters.

The known data acquisition system [1] contains a memory device with a set of instructions and a processor configured to execute a set of instructions to perform one or more operations.

The set of operations, according to the well-known solution [1], involves the use of a group of signals associated with a set of sensors in the vehicle, the use of a group of filters to create filtered signals, then events are detected by comparing event estimates based on a set of filtered signals with an event threshold.

The system under consideration is focused on productive work and has sufficient potential to process information about the state of the vehicle, current road conditions, as well as the state of the driver driving the vehicle.

The considered variant of the data acquisition system has the ability to continuously and dynamically adjust the type of collected signals in order to modify the data mainly in real time. The system is capable of adjusting parameters based on their changes for the purpose of controlling the updating of variables over time, and in some cases the controlled variables may be based on information related to the vehicle, road, environment, driver, or other factors.

It should be noted that the well-known data collection system [1] has a non-standard architecture and uses complex protocols for the exchange of information and its processing during direct operation, which will inevitably require a number of preparatory measures related to the replacement and / or re-profiling of standard road equipment used in transport networks, and this, in turn, is associated with a significant increase in the cost of starting a mass production of systems with a view to their large-scale use in the road transport sector.

An additional disadvantage should be considered the complexity of maintaining the known data collection system, since an extensive list of interrelated programs is involved in the work, and a temporary stop in the operation of one of them can lead to a large-scale system failure, which will adversely affect the operation of the transport network.

The closest in terms of technical essence to the utility model under consideration should be considered a device for transmitting information for a vehicle (see RU189705, class B60R25 / 00, published on May 30, 2019 [2]).

The well-known solution [2] refers to devices for transmitting information, its visualization, as well as for connecting to vehicle systems.

A computer known from the prior art [2] for a land vehicle contains an electronic base with a control unit placed on it, a signal conversion and switching device, communication interfaces, data processing devices and microcontrollers.

The considered solution [2] provides the task of stabilizing the quality of the output signal, and also provides connection to the standard vehicle systems of any external devices with the ability to read their contents, in addition, the integration of the device for various types of vehicles is greatly facilitated.

A significant drawback of the known solution [2] should be considered low performance and low potential for widespread use, since the structure of the device implies a certain set of well-known components, the scope and purpose of which are defined and relate to a number of limited tasks that do not allow development and the possibility of using in complex transport systems , the management of which is associated with the processing of ever-increasing information flows.

An additional disadvantage of the device [2] is the narrow possibilities of assignment, limited by the available possibility of one-way transmission of information for subsequent review by the driver or vehicle users, which hinders the operational capabilities of the device and casts doubt on the feasibility of using a narrowly focused electronic device that is not capable of simultaneously working on a wide range of tasks in in an ever-increasing amount of information that it is desirable to take into account in order to ensure a high level of road safety.
