Description
Purpose: The stand should be intended for carrying out a set of practical work to study the operating principle of the microprocessor ignition system of cars, trucks and tractors, the principles of their operation and operating modes, as well as the formation of initial skills in vehicle maintenance and repair in the courses “Automotive Equipment Design”, “Operation of Automotive Equipment”, “Design and Calculation of Automotive Equipment”.
Description: The tablet stand must be a frame structure, on the front panel of which a color schematic diagram of the microprocessor ignition system must be applied. To ensure clarity, an LED backlight must be built into the image of the microprocessor ignition system. The LED backlight should provide a dynamic display of the operating principle of the microprocessor ignition system. An electronic logic device based on the ADCS-P-5 controller must provide interconnection between the LED backlight of the stand and the backlighting of the names of elements included in the microprocessor ignition system and implement two modes of operation of the LED backlight: training and control. In the training mode, the teacher should be able to give a description of the elements of the microprocessor circuit of the ignition system, highlighting each element and its name with a magnetic pointer. In control mode, the student should be able to independently compare the existing elements of the microprocessor circuit of the ignition system with the corresponding names located in a special sector of the tablet. The electrical circuit of the stand must be powered by a standard switching power supply. The power cord connector and power supply switch must be installed on the side panel of the stand.
A controller type ADCS-P-5 must have the following technical characteristics: architecture type: RISC; bit depth: 8-bit; clock frequency: up to 16 MHz; program area size, at least 8 KB; RAM size, at least 512 Bytes; EEPROM size: not less than 512 Bytes; , at least 8 analog inputs, , at least 4 analog outputs; , at least 24 discrete inputs/outputs; interface support: USB, RS-232, RS-485, SPI, I2C with voltage from 0 to 10V, from 4 to 20mA; support for sensors: strain gauges, thermal resistances, thermocouples, digital micrometers, induction sensors, optocouplers with an open optical channel; peripherals, at least 8-bit DAC, at least 10-bit ADC, at least 8/16-bit PWM, at least 8/16-bit counter-timer, analog comparator, optically isolated open collector type outputs, current switches; supply voltage from 9 to 17 V.
