Description

The utility model relates to the field of measuring equipment, specialized timekeeping, specifically to time chronometers of the exposure of harmful production factors to workers of automobile rolling stock, can be used to monitor the exposure time of an increased level of noise and vibration to a car driver during his work shift, as well as for monitoring the time spent by the driver driving the car in order to correctly assess his working conditions.

The inventive utility model relates to priority areas for the development of science and technology - "Technologies for processing, storage, transmission and protection of information" [Alphabetical subject index to the International Patent Classification in priority areas for the development of science and technology / Yu.G. Smirnov, E.V. Skidanova, S.A.Krasnov. - M .: PATENT, 2008. - p. 49], since it solves the problem of accurately determining the time of exposure of harmful production factors to the driver of automobile rolling stock.

It is known that when the accelerator pedal of an automobile rolling stock is pressed, the driver is affected by such harmful production factors as noise and vibration, the level of which, as a rule, exceeds the maximum permissible values, so it becomes necessary to measure the time during which these harmful production factors affect driver of automobile rolling stock.

A device for the study of visual fatigue (RU No. 20456 U1, IPC A61F 9/00, published November 10, 2001), comprising an electronic chronometer, an electronic chronometer control device, a digital time indicator, an LED analyzer, an audible alarm device and a keyboard, the keyboard has replaceable randomly localized optotypes with two angular sizes.

Signs of an analogue that coincide with the essential features of the claimed device are: an electronic chronometer as part of the device, an electronic chronometer control device.

The disadvantages of the analogue:

1. The device is intended only to determine visual fatigue;

2. The device is not intended for use in motor vehicles.

In addition, this device does not solve the problem of measuring the time of exposure to noise and vibration on the driver of an automobile rolling stock.

A known device "Vibration meter" (RU No. 2439508 C1, IPC G01H 17/00, published 10.01.2012), used to measure the level of vibration. Achievable technical result of the claimed invention is to increase the accuracy of measuring the level of vibration. The difference lies in the design - the vibration meter contains an emitter, a two-coordinate sensor that measures vibration parameters installed in the housing, two flat-panel displays, the device also contains an additional sensor made in a separate housing. The inventive device contains only an electronic timer for determining the time of exposure to harmful factors, the housing and the system of springs.

A common feature of the claimed utility model with an analogue is the presence of a housing.

The disadvantage of an analogue is the large weight and volume of the device. This device also does not solve the problem of measuring the time of exposure to noise and vibration on the driver of automobile rolling stock.

It is also known device "Noise and vibration meter" (RU No. 2308007 C1, IPC G01H 17/00, published 10.10.2007), designed to measure noise and vibration. The noise and vibration meter includes a measuring microphone, an amplifier unit, a filter unit, a power detector unit, an indication unit, a control unit with switches and an indication of the magnitude of the measured noise and vibration levels, as well as a power supply unit. The display unit is made in the form of an interconnected voltage converter, microcomputer, timer, random access memory and communication means of the noise and vibration meter with an external computer. The amplifier unit, the filter unit, the power detector unit are provided with registers and are connected to the display unit microcomputer, while the power detector unit contains a range controller, and the control unit is equipped with a keyboard controller.

Signs of an analogue that coincide with the essential features of the claimed device are: a housing, a timer for operation as part of the device, and a power supply.

Despite some advantages, expressed in the accuracy of determining noise and vibration levels at workplaces, the disadvantages of this device include:

- the cumbersome design of the device, which does not allow efficient use of it for a long time to evaluate harmful factors in cramped conditions (for example, in the cab of a motor vehicle);

- the inability to determine the time of exposure of harmful factors to the employee, due to the impossibility of the device interacting with the mechanical parts of technical devices that are sources of harmful factors;

The specified analogue also does not solve the problem of measuring the time of exposure to noise and vibration on the driver of automobile rolling stock.

In addition, in the analogue there is no possibility of fixing the device to the mechanical parts of technical devices that are sources of harmful factors, and therefore, it is necessary to have an operator to use this device, while the inventive device takes readings completely offline (with the exception of installation and removal devices from the design of a technical device, for example, a car).

From the prior art, no devices have been identified that solve the problem of measuring the time of exposure to increased noise and vibration on the driver of an automobile rolling stock and the essential features that are similar in combination with the claimed device.

The problem to which the claimed utility model is directed is to create a device for determining the time of exposure of harmful production factors to the driver of a vehicle, including noise, vibration and time spent in a fixed working position, which does not cause inconvenience to the driver when operating the car.
