Description

The actual training kit for exercising electrical and electromagnetic circuits}

The present invention relates to a training kit for electrical and electronic training, and more particularly to a training kit for electrical and electronic training consisting of a system necessary for education / practice such as digital scope, training board, in-circuit emulator as a system.

In general, training kits for electrical and electronic training are used to study the functions of microcomputers, programming and input methods, and design of automatic circuits in industrial research institutes related to electrical and electronic engineering, engineering colleges, and vocational training institutes. Use to teach

In the past, the breadboard (the device that is partially required in the electrical and electronic circuit experiment)

BreadBoard), a function generator, a digital scope, a DC power supply, etc., or to experiment with the application process of electrical and electronic circuit experiments, such as controlling the speed of a motor using a microcomputer, using seven segments, and displaying the LCD. The electric and electronic circuits were manufactured by function kits, and the parts included in the kits were sequentially assembled and tested.

However, it is inconvenient for the practitioner to separately prepare various devices necessary for electric and electronic circuit experiments, and when experimenting with a pre-made kit, the practitioner can design only the specific experiments that are included in the kit. There is a problem that the effect of the practice is reduced because the automatic circuit cannot be actively tested.

In addition, in order to use EEPROM or non-volatile memory embedded in the microcomputer, you need to purchase a separate ROM writer and burn the program. Therefore, the execution process of the program is complicated and debugging to remove the bug included in the program. There is a problem that you have to burn the program every time with ROM Writer.

In particular, there is a problem in that an expensive digital scope must be purchased separately in order to measure the characteristics of the circuit and characteristics of each device for comparing / analyzing the input signal and the output signal.

The present invention has been devised in view of the above problems, and its purpose is to provide a low cost experiment by lowering the manufacturing cost by configuring the necessary equipment for education / practice such as digital scope, training board, in-circuit emulator, etc. into one system. It is to improve the convenience of experiments by making it possible to purchase equipment and to practice the design and application process of automatic circuits without additional experimental equipment.

FIG. 2 is a block diagram illustrating the training board of FIG. 1.

Referring to FIG. 1, the training kit for electric and electronic training of the present invention includes a power supply 10, a training board 20, an in-circuit emulator 30, and a digital scope 40 as one system. have.

The power supply device 10 transforms an AC voltage applied from the outside to supply a DC voltage to various devices connected therein.

The training board 20 may design a circuit using electrical and electronic elements such as resistors, ROMs, RAMs, capacitors, microcomputers, and the like, and may test the electrical and electronic characteristics of the circuit by comparing the input and output signals of the designed circuit. In particular, it enables the learner to actively learn the functions of the microcomputer, program writing, and input methods.

The training board 20 is a bread board 21 that can be connected using a jump wire (Jumper Wire) without soldering each element constituting the electrical and electronic circuit, and to change the opening and closing of the electrical circuit A plurality of switches 22 to be used, an RS-232C communication port 23 connected to an external PC for transmitting and receiving data, a keypad 24 for inputting various commands to check the operation state of a circuit, A drive unit 25 provided with a drive for driving a DC motor, an AC motor, a stepping motor, etc., an LCD 26 for displaying the operation state and instructions of the circuit in Korean and English, and other than the LCD 26 In order to experiment with the display devices, I / O expansion unit 27 equipped with an external display device such as Seven Segement, Dot Matrix, etc., and a circuit completed by experiment and practice are composed of IC. Well, it consists of a programmer socket 28 that can check the operation status of this IC.

The in-circuit emulator 30 may bake a program directly into a non-volatile memory that is embedded in the microcomputer or detached from a bread board without a separate writer, and may also burn a debugged program directly into a memory without a separate writer.

The digital scope 40 measures almost all kinds of signals related to waveforms such as pulse rise, fall time, overshoot, along with basic characteristics such as magnitude, shape, frequency, and phase of electric quantity, that is, voltage and current.

As described above, the present invention provides a low-cost experimental equipment to consumers by lowering the manufacturing cost by configuring the equipment necessary for education / practice such as a digital scope, a training board, an in-circuit emulator, etc. into a single system, and providing an automatic circuit. It improves the convenience of experiment by allowing the design and application process of to be practiced without additional experimental equipment.
