Description

Devices are known for recording information on a magnetic cassette with its subsequent processing under stationary conditions.

However, such devices are very complex and have a limited time resource.

A disadvantage of the known device is high complexity and low reliability.

Closest to the proposed technical essence is a device for recording performance indicators of vehicles, containing track, fuel and time sensors, three decoders, meters, a switch and a unit for specifying the type of road surface [2].

The disadvantage of this device is the presence of complex meter designs that determine the complexity of additional processing of control data (recording, coding, etc.) for subsequent machine processing of information about the transport process. In addition, the device has a relatively low operational reliability.

The purpose of the invention is to simplify and improve the reliability of the device.

This goal is achieved by the fact that in the device for recording vehicle performance indicators, comprising a track sensor, a fuel sensor and a time sensor, current generators, keys, an electrical connector, electrochemical integrators and pulse shapers are introduced, the inputs of which are connected to the outputs of the track and fuel sensors, the outputs of the current generators are connected to the first inputs of the keys, the second inputs of which are connected to the outputs of the pulse shapers, the outputs of the keys through the contacts of the electrical connector are connected to the inputs of ektrohimicheskih integrators timer is made of the alternator, the output of which through the contact electrical connector connected to the input of the electrochemical integrator.

The drawing shows a diagram of the proposed device.

The device operates as follows.

When installing a removable cartridge 11 in the working position through the electrochemical integrator 10, current flows, the amount of charge on the integrator 10 is proportional to the time of the vehicle.

The fuel consumption channel works as follows.

Information about the fuel consumption is recorded in the electrochemical integrator 7 from the current generator 3, while the fuel sensor 2 (volumetric flowmeter) generates after passing through it into the power system a certain portion of the fuel signal that triggers the pulse shaper 4, a pulse of which of constant duration opens the key 5 and generates a current pulse from the current generator 3.

The work of the path traveled channel is organized similarly to the operation of the fuel flow channel, and the proximity sensor 1 of the path, connected through the transfer gearbox to the speedometer drive shaft, generates a signal when the vehicle travels a certain distance.

Electrochemical integrators 12 and 13 are used to record the address

4761 ₄ formations: personnel number of the driver and number of the vehicle.

Information is read from a removable cartridge at the control room.

At the control room, an information cassette is prepared to record operational performance. To this end, each electrochemical integrator undergoes a cycling operation to ensure normal operation. In the final cycle, the working electrode is cleared of charge and the information cassette is ready to record data. .

Thanks to the use of a removable cartridge with electrochemical integrators, it is possible to expand the functional capabilities of the device, increase operational reliability, which is achieved by using an electrochemical integrator as a recording element, to automate the process of reading the accumulated information, and to exclude the factor of subjective assessment of recording data.
