Description

The utility model relates to the means of registration and control of the technical condition of a vehicle. The device for monitoring the technical condition is intended for installation on general purpose vehicles and can be used on military vehicles and tracked vehicles.

Known device for diagnosing a vehicle, containing a microprocessor, a unit for interfacing the microprocessor with a serial data transmission channel. This device additionally contains a sound synthesizer unit, a unit for measuring the outside temperature, a unit for measuring the fuel level in the tank, connected to a microprocessor [1].

The main disadvantages of the system are the impossibility of realizing the technical condition of the vehicle on the basis of standard vehicle sensors, the lack of means of notifying visual information of the current state of the vehicle, notifying the driver about the technical condition of the vehicle.

Another disadvantage of the described device is the limitation of the fixed parameters, the inability to control all the parameters characterizing the technical conditions of the vehicle.

This technical solution expands the functionality of diagnostics, but it is not enough to ensure the possibility of observing the signals of all circuits of interest in the vehicle.

A device is known that includes a removable unit in which a processor is installed, a device power supply connected to a battery, a device status indicator panel, an analog-to-digital converter, the information inputs / outputs of which are connected to the sensors installed on the vehicle, and the processor information inputs are connected with the outputs of the analog-to-digital converter, and the information output with the onboard clock, in addition, the information outputs of the status indicator panel are connected to the power supply unit of the system [2].

The disadvantage of the described device is the limitedness of the recorded parameters, the inability to control all parameters characterizing the technical conditions of the vehicle, namely the technical condition of the vehicle on the basis of standard vehicle sensors.

The problem to be solved by the claimed utility model is to expand the functionality of the device and the accuracy of monitoring the technical condition of the vehicle.

The problem is solved due to the fact that in a device for monitoring the technical condition of a vehicle, containing a block of standard sensors, a microprocessor, a microprocessor control unit, a multifunction display, a synthesizer of sound signals, an analog-to-digital converter, the information inputs / outputs of which are connected to the block of standard sensors monitoring the parameters of the technical condition of the engine and sensor units monitoring the parameters of the technical condition, characterizing the state of the hydraulic fluid, while

the information inputs of the microprocessor are connected to the outputs of the analog-to-digital converter, according to the utility model, they are additionally introduced into the sensor unit for monitoring the parameters of the technical condition of the engine - an oil quality sensor, and in the unit for monitoring the parameters of the technical condition characterizing the state of the hydraulic fluid - indicators of hydraulic fluid pollution, the outputs of which are connected with inputs of an analog-to-digital converter, in addition, a read-only memory and a unit for interfacing with a personal computer are introduced.

A feature that distinguishes the proposed device for monitoring the technical condition of a vehicle from the known one is the introduction of an oil quality sensor into the sensor unit for monitoring the technical condition of the engine.

Contamination of engine oil leads to abrasive wear of parts of the internal combustion engine, which occurs due to the ingress of solid particles into the layer of liquid lubricant separating the friction surfaces, which causes the contact of these particles with rubbing surfaces. Any mechanical impurities, the dimensions of which exceed the thickness of the boundary oil layer, cause disruption of the integrity of the oil film and cause contact with metal surfaces, causing increased wear of parts of the internal combustion engine of the internal combustion engine. Thus, the registration of the maximum permissible engine oil standards by the oil quality sensor significantly increases the accuracy of monitoring the technical condition of the vehicle.

Another feature that distinguishes the proposed device from the known one is the introduction into the sensor unit for monitoring the technical condition parameters characterizing the state of the hydraulic fluid-indicator of pollution. If the pump and the piping connected to it heat up quickly, this indicates that the hydraulic fluid is contaminated. As you know, excessive heating of units and parts of the hydraulic system leads to the failure of units and units. Therefore, the control of the contamination of the hydraulic fluid increases the quality and accuracy of the control of the technical condition of the vehicle.

For example, any device complying with GOST 31247-2004 “Industrial cleanliness. Determination of Liquid Contamination Using Automatic Particle Counters ”. Of the devices for controlling the purity of a liquid, serially produced, to perform the functions of a sensor for monitoring the purity of a liquid in the proposed device, the following can be used, for example: "Aurora" St. Petersburg, designed for automatic measurement of the counting concentration of particles of mechanical impurities in liquids in accordance with GOST 17216; 2) Liquid purity control device PKZH-904 manufactured by OJSC NITI-Tesar Saratov, allowing to quickly control the purity of liquids in accordance with the requirements of GOST 17216-2001; 3) Laser pollution monitor LCM20.2021 / 2023 (Operations Manual.pdf) by Parker Yannifin Ltd, Holland; 4) Av Count model SA1000 liquid particle counter from Stunhope-Seta UK. In the best version of the proposed device, a device for monitoring the purity of a liquid in a flow of ICH, manufactured by LLC "Research Center" Teas-MO ", is used as a sensor for monitoring the purity of a liquid.

Another feature that distinguishes the proposed device for monitoring the technical condition of a vehicle from the known one is the inclusion in the device of a read only memory (ROM) with a unit for interfacing with a personal computer.

Thus, at any time the device can be connected, for example, to a laptop and in real time the operator can observe the critical parameters of the vehicle state, thereby preventing a pre-emergency situation. And also to record all parameters in ROM and further analyze the operation of individual units and mechanisms of the vehicle.

3 - sound signal synthesizer,

4 - indicator of contamination of the hydraulic fluid,

5 - oil quality sensor,

6 - block of standard sensors,

7 - multifunctional display,

8 - read only memory (ROM),

9 - a unit for interfacing with a personal computer.

A device for monitoring the technical condition of a vehicle, contains a microprocessor 1, the outputs / inputs of which are connected to a unit of standard sensors 6 and a read-only memory 8, as well as to the outputs of the indicator (sensor) of contamination of the hydraulic fluid 4 and to the outputs of the oil quality sensor 5. In addition, to the inputs of the microprocessor 1, a sound signal synthesizer 3, a control unit of a microprocessor 2, a multifunction display 7, a read-only memory (ROM) 8, an interface unit with a personal computer 9 are connected.

A device for monitoring the technical condition of a vehicle works as follows. When the oil quality sensor registers 5 maximum permissible engine oil standards, as well as with the indicator (sensor) of the contamination of the hydraulic fluid 4, the signal is sent to the microprocessor 1. It is possible to install several indicators (sensors) of the contamination of the hydraulic fluid 4. Further, when comparing the measured parameters on the microprocessor, 1 signal s the microprocessor is fed to the inputs of the audio signal synthesizer 3 and the multifunctional display 7. Then an audio signal occurs at the output of the audio signal synthesizer 3 about the warning of maximum permissible norms and the appearance of visual information in real numbers on the multifunctional display 7. In addition, the information from the standard sensors is processed by the microprocessor 1 and transmitted to ROM 8. So that the device could be interfaced with a computer through an interface unit with a personal computer 9 for further information processing and assessment of the technical condition of the vehicle.

This device can be used both on the base chassis, for example, a truck crane, and on working equipment, that is, directly on the mechanism for lifting, moving loads. For example, in a hydraulic system that controls the mechanisms of a machine and consists of a pump, a hydraulic tank, pipelines and hydraulic equipment. This device of the automobile crane works as follows: the pump takes oil from the hydraulic tank, transfers it to the hydraulic valve, from where it transports it through the pipelines to the executive hydraulic cylinders.

Full-scale tests of the proposed device have shown the high efficiency of the claimed proposal.
