Description

The proposal relates to teaching aids and can be used to increase the effectiveness of the educational process in the discipline of electrical equipment of automotive vehicles.

A well-known vehicle lighting system in which the algorithm for troubleshooting is carried out (V.N. Li Gui-chin. Lighting and instrumentation. Study guide. - Chelyabinsk: CHVVAIU, 1985. - 90 p.), The use of which is possible only on the car itself.

The disadvantage of this system is the inability to use the car in small audiences, the difficulty of learning to troubleshoot the lighting system due to the huge number of wires of other systems, as well as the inability to explain the material to a large number of trainees and the high risk of the system lighting the car out of order due to the fault of the trainees themselves.

Known bench simulator for detecting faults in the car alarm system (Utility model "Bench simulator for determining faults in the car alarm system", patent No. 37430 dated 04/20/2004. Authors kit Terentyev I.V., p / p- to Pochkaev Yu.V., set Gizatullin PP)

The disadvantage of this simulator stand is that it cannot be used to determine malfunctions in the car lighting system.

This lighting system is the closest to the proposed stand-simulator in technical essence and is taken as a prototype.

The objective of the proposal is to increase the effectiveness of learning the causes of malfunctions in the vehicle lighting system.

The simulator stand is a box on which the lighting system devices are fixed. The frame of the box is a frame made of a metal corner 25 × 25 millimeters and sheathed with plywood sheets. The size of the simulator stand 1450 × 600 × 250 millimeters (figure 1).

The front side of the simulator stand (figure 2) is divided into two parts: on the left side there are devices of the lighting system: car headlight FG-140 (2 pcs.) - 1; front lamp PF133-B (2 pcs.) - 2; light of the road train unitary enterprise 101-V (3 pcs.) - 3; taillight FP133-B (2 pcs.) - 4; flashlight for body lighting - 5; license plate light - 6; fuse box - 7; foot switch - 8; central light switch - 9; mass switch - 10; cab light - 11; engine compartment lamp - 12; current indicator AP 171 - 13; control lamp of the road train speedometer with a high-beam warning lamp - 14; fuel gauge with high beam - 15; mock-ups of battery covers (2 pcs.) - 16. On the right, an electrical diagram of the lighting system is drawn - 17; and also there is a switch for the fault input unit - 18; and instructions for the operation of this simulator stand - 19.

Lighting devices are mounted using metal mounts shown in the drawings. All elements of the stand are interconnected using connecting wires. To power the simulator stand, you need a 27 V transformer and a rectifier unit for a 24 V transformer.

The proposed stand simulator works as follows.

Input faults is carried out through the contacts of the respective relays (figure 3). For this, one of the wires (most often with a positive potential) is passed through a relay. When the relay is activated, the contacts open, as a result of which the circuit we need breaks, the consumer switched on does not work. The simulator stand includes nine faults.

1. The engine compartment lamp does not light - an ammeter break to the lamp. The fault is introduced through the contacts K4, K5 relay P 1;

2. Codlight illumination - a break in the positive wire from the rear gauge. The fault is introduced through the contacts K4, K5 of relay P2;

3. Road train warning lamp - wire break. The fault is introduced through the contacts K4, K5 of the relay P3;

4. The upper rear position lamp does not light - wire breakage. A malfunction is introduced through the contacts K4, K5 of relay P4;

5. Cabin light does not work - wire break. The fault is introduced through the contacts K4, K5 of the relay P5;

6. The high-beam warning lamp does not light - wire breakage A malfunction is introduced through the contacts K4, K5 of relay P6;

7. The upper front position lamp is off - wire break. The fault is introduced through the contacts K4, K5 of the relay P7;

8. The top headlamp does not light high beam - wire break. The fault is introduced through the contacts K4, K5 of the relay P8;

9. Two lights of the road train do not work - wire break. The fault is introduced through the contacts K4, K5 of the relay P8;

Instructions for working with the stand.

The simulator stand is a stationary installation and must be operated indoors at temperatures from 0 to plus 35 ° C, relative humidity up to 80 percent.

It is necessary to protect the simulator stand from bumps and drops, moisture entering the lining and inside the stand.

There should not be dust in the air of the room, which conducts electric current, corrosive vapors and gases corroding metals, paints and coatings insulation.

To enable the simulator stand, it is necessary to insert the plug into an AC outlet with a voltage of 220 V, frequency 50 Hz. At the same time, 24 V voltage is supplied to the devices of the electrical systems of the stand and to the fault input unit. Switch on the mass switch.

To turn on the dimensions or the dipped beam, it is necessary to extend the rod of the central light switch to the first or second position. To turn on the lights of the road train, the ceiling of the cab, the engine compartment lamp, you must turn on the corresponding toggle switches.

To enter this or that malfunction, it is necessary to turn the switch knob to the position corresponding to the malfunction. Moreover, the zero position, in which the entire system is operational, is the extreme left position of the switch.

To disable the stand you must:

1. turn off all devices (headlights) using the controls.

2. Turn off the Mass switch.

3. Unplug the plug from the power outlet.

Compared with the prototype, the proposed simulator stand has the following advantages:

1. More effective troubleshooting training;

2. Visibility of training, the possibility of practical use of the simulator stand and showing simultaneously a large number of students;

3. The ability to use the stand while in an audience of any size;

4. The ability to learn how to troubleshoot a lighting system in practice (without deliberately creating a malfunction in a car, which takes a lot of time, that is, it saves time and money)
