The present invention relates to a human cerebrospinal fluid nervous system stimulation transmission model and control circuit, and more specifically, to the human cerebrospinal fluid model device for observing the stimulation path according to external stimulation and the body's response to the stimulus It relates to a control circuit.

In general, the human cerebrospinal fluid model apparatus is used as a means for three-dimensionally expressing the shape of each brain and spinal cord existing in the human body, the existing human cerebrospinal fluid model is only enough to confirm the three-dimensional structure of the human cerebrospinal cord.

The necessity of a model for observing the human body's cerebrospinal nerve system stimulation and transmission for the concept of stimulation and reaction of the human body is a result of a survey conducted by current elementary school teachers. The second and second semester, Section 2, Body Movement and Growth, shows the structure of the 6th and 7th poets' nervous system and the transmission process of the stimulus. Results In particular, the structure of the nervous system and the transmission process of the stimulus are difficult to observe with the eyes, so it is very difficult to understand the concept when learning about the human body.

The human cerebrospinal fluid related model, which is currently introduced in Korea and possessed in frontline schools, is not only very helpful for learning because it is the level of pictures presented in textbooks, and is rarely used in teaching.

As a conventional technique related to this field, the conventional technique introduced in "Japanese Utility Publication No. 51-132059, Acupuncture Point Display Device" turns on and off the power by switch 6 in the schematic diagram of FIG. The switch is used to determine the LED to emit light, which is operated by a passive element (Relay or Switch). In the above, the human body diagrams of the front, back, and side are shown on a predetermined plate, and each acupuncture points are placed, and a power point, a partial selection switch, and a symptom selection switch are arranged on one side. Illumination of the required points of the acupuncture points is illuminated ", but the circuit of the acupuncture points display device as shown in FIG. 1 is a conventional dot matrix driving circuit as shown in FIG. In the dot matrix driving circuit proposed in the present invention, as shown in FIG. 2, the control circuit includes two passive switches between the line and the scan side control signal line. By adopting only one transistor, the circuit is simplified and the cost is reduced.The output X0 ~ X15 of the upper 74LS574 is the data side by the program of the controller. As a control signal, it was input to a PNP type transistor, and a closed circuit was formed by the output terminal (scan side control signal) of the LED, resistor, and bottom 74HC574, and when the driving circuit was composed, 16 resistors were replaced in the case of a 16 × 16 dot matrix.

In addition, U.S. Patent 4,561,851 is "a device for demonstrating and pointing to the neural stimulation in the correct position according to the location of the affected area," in the case of the circuit used in this device is attached to each of the de-flip-flop output stage Therefore, in order to emit 256 LEDs, a total of 32 Octal D-FlipFlopes are required, but in the proposed circuit, even though 256 LEDs are emitted using a dot matrix, all 4 As a circuit with technical progress as it is possible to use two octal flip-flops, in the conventional technology, the present invention seeks to model the human cerebrospinal fluid nervous system stimulation transmission observation system for the concept of stimulation and reaction of the human body and its control circuit. "The technical task and composition to achieve is different.

In view of the above, the present invention has a problem in displaying the human cerebrospinal fluid stimulus transmission path and response according to the conventional human body model, and an object of the present invention is to solve the above problems. It is to provide a device and a circuit for displaying.

Therefore, because the learning is done through the direct manipulation of the model by expressing the path and response form of the stimulus transmission through the LED and the voice device by the microcontroller, the interest in the learning is replenished. It is to make it easy to acquire concepts about structure and function.

That is, the present invention allows the visual linguistic confirmation through the position and shape of each part of the nervous system through the brain, the taste sensing process through the tongue, and the visual linguistic confirmation through the manipulation of the model. Through the model manipulation, the user can visually and verbally check the elbow reflection visually and linguistically through the model manipulation, and easily obtain the concept of it, and directly manipulate and confirm the overall process of stimulus transmission and reaction. By doing so, the effect of learning on the structure and function of the nervous system can be enhanced.

In addition, the above functions are controlled and displayed through the microcontroller and the remote controller to make the structure and function of the nervous system easier to understand.

Example 2

Microcontroller (11a; AT89C51) that operates in conjunction with an external stimulus applied by a switch unit 17 for directly inputting taste, touch, knee reflection, etc., which is an external stimulus, and a remote control sensor circuit unit 16, which is a remote control device. Connected to the de-flip flop 11d; 74HC573 in series, so that the ROM 11b; 27C512 and the RAM 11c; 62C256 are configured in parallel with respect to the controller 11 and the external stimulus inputted to the controller 11; Applied to the base terminal of the transistor 19 connected in series to the output of the de-flip-flop 14 (74LS574) to be sent to the memory decoder (13; 74HC138) which selects the latch portion for outputting the signal and displays the magnetic pole path. At the same time, the data signal output from the control unit 11 to the input terminal of the de-flop flops 15 and 74HC574 at the lower end by a program written to the ROM 11b; 27C512 of the control unit 11 Drive LED by applying to base terminal connected to emitter terminal in series (18) is sequentially driven, and when the stimulus path represented by the LED reaches the first stimulus input, one of the voice signals stored in the ROM (11b; 27C512) of the control unit 11, another de-flip A ladder-type D / input connected to the output terminal of the D-flip flop 12a; 74LS574, which is outputted by the decoder / demultiplexer which is input to the flop 12a; 74LS574 and used as the memory decoder 13; 74hc138. The A converter 12b is converted into an analog signal and then amplified by the audio OP amplifier 12c and output to the speaker 12d.

The operation of the model control circuit for human cerebrospinal nerve system stimulation transmission observation of the present invention configured as described above will be described.

First, as illustrated in FIGS. 5, 7, and 8, the output signal of the microcontroller 11a can be largely classified into two types.

This is for operating the LED, the de-flip flop 14; 74LS574, 15 for selecting the LED to operate with the data signals D0 to D7 of the P0 port input to the D flip-flop 14; 74LS574, 15; 74HC574. A signal A0 to A2 input to the memory decoders 13 and 74HC138 for outputting a signal input to the CLK terminal of another de-flip-flop 12a; 74LS574 for outputting an audio signal; .

On the other hand, the data signal (eight control signals) of the microcontroller is connected to the input pin of the de-flip flop which serves as a data latch. These data signals are outputted to the output pins only when pin 11 OE of the 74LS574 or 74HC574 is low and the signal of pin 1 CLK changes from low to high. Done. In other states, the signal is always kept.

In addition, the control of the memory decoders 13 and 74HC138 by the selection signal of the microcontroller 11a is performed only when the G1 of the 74HC138 is high and the G2A and G2B pins are always kept low. This 3x8 decoding operation is performed. In this control circuit, the G2A and G2B pins are always kept low and the 74LS138 is controlled by controlling the G1 pin. Among the address signals outputted from the control unit, three signals (decoder selection signals) A0, A1, and A2 are connected to A, B, and C of the 74HC138, respectively, and 74LS574 or 74HC574 to be operated by controlling this signal is selected.

When the switch unit 17 or the remote controller 16 applies an input for an external stimulus to the control unit 11, the LED arranged according to the neural path according to the external stimulus input from the control unit 11 is turned on and a predetermined voice is input. Is output through the speaker 12d.

At this time, examples of the external stimulus input are visual nerves, taste nerves, motor nerves (hands and knees), spinal cord nerves, cerebral, cerebellum, hepatic brain, middle brain, soft water, etc. In addition, the remote controller 16 inputs each external stimulus input to the switch unit 17 at a short distance.

The D0 to D7 signals output from the control unit 11 are connected to two 74LS574 and two 74HC574 input pins serving as latches. This data signal is outputted to the output pin only when the pin 11 OE of 74LS574 and 74HC574 is low and the signal of pin 1 CLK is changed from low to high. Done. In other states, the signal is always kept.

The data signals D0 to D7 are inputted to the 74LS574 at the top to determine the rows of the LED matrix and the 74HC574 at the bottom to determine the columns and the operation of the LEDs. When the LED is operated, a resistor (R) that prevents reverse flow of current when the LED is operated is connected in series with the base terminal of the transistor 19. When a signal is applied to the base terminal of the transistor, it is connected to the output terminal of the upper 74LS574. The transistor conducts and turns the selected LED on / off in accordance with the transmission order of nerves stored in the ROM of the controller.

When a high signal is output to the upper 74LS574, the selected LED is turned on when the lower 74HC574 output terminal becomes low.

The selection of the operation LED is determined by the data signals D0 to D7 output from the top two 74LS574 and the data signals D0 to D7 output from the bottom two 74HC574, where D0 of the first 74LS574 is high and the first 74HC574 If D0 is low, LED 1 operates.If D0 of the second 74LS574 is high, if D0 of the first 74HC574 is low, LED 129 operates and D7 of the first 74LS574 is high. If the first 74HC574's D7 is low, then LED 120 will operate. In this way, the stimulation path is displayed by operating the LEDs arranged along the human cerebrospinal fluid nervous system.

The audio signal stored in the external ROM of the control unit 11 as a binary file or a hex file is latched to another 74LS574 (12a) in addition to the 74LS574 that controls the LED, and then a signal is input to the 74LS574 CLK terminal by the 74HC138 selection signal. After being converted into an analog signal through the bit ladder type D / A converter 12b, it is amplified by the audio OP amplifier 12c (LM386) and output as sound through the speaker 12d.

For reference, in order to create a program for controlling the human nervous system used in the present invention, as shown in FIG. 6, the basic time period 50 [mSec] of the entire program using the internal timer / counter of the microcontroller 11a is used. Set. In order to apply the set basic period to the entire program, the internal timer / counter of the microprocessor was set and the time period was programmed.

Each number was set to two 74LS574 and two 74HC574, up to 256 LEDs, so that the LEDs to be controlled can be precisely controlled. This uses the output pins of the memory decoder 74HC138 to sequentially place 74LS574 and 74HC574, and one 74LS574 has eight outputs, so that they are arranged in sequence. Therefore, LED 1 is selected for D1 of the first 74LS574 and first 74HC574, and LED 17 is selected for D1 of the second 74LS574 and D1 of the first 74HC574.

Then, we changed the CLK of 74LS574 and 74HC574 related to the LED number to be controlled, and created a program function in which the information to be controlled is transmitted through the data line.

With the overall configuration of such a program, a basic time period was set using the internal timer interrupter of the AT89C51 microcontroller 11a, timer 0 was set to 16Bit timer, and a program function was written so that the time period was 50ms.

The present invention constructed as described above for the human cerebrospinal fluid nervous system stimulation transmission model and its control circuit can learn the structure of the human cerebrospinal fluid and nerve system stimulation transmission observation through the process of the learner can directly induce interest in learning, intuitive Through the data, the concept of the structure and function of the nervous system can be easily learned.

On the other hand, according to the control circuit for the device of the present invention, the human cerebrospinal fluid model box in which the LED is placed along the cerebrospinal fluid nervous system placed in the conventional human body model (2) to express the response to the current external stimulus used in the present invention. Although rigidly expressed in (1), when using a material that can be deformed in a joint or an eyeball, the function of motion that can express the form of reaction as a physical motion using a DC motor can be applied in various ways.

In addition, when connected to an external PC by serial communication using the RS232 communication port of the microcontroller (AT89C51) used in the present invention, it is possible to use a three-dimensional, the microcontroller AT89C51 has an internal ROM and internal RAM No external ROM or RAM is required, which has many advantages in terms of price and space. In addition, the microcontroller used has four input / output ports and two 16-bit timers / counters to enable various program control, which is very suitable for controlling the developed human neural model. Therefore, the present invention interfaced the EP-ROM and the SRAM to an external memory in order to add various functions to the human neural model.

The P89 port output of the AT89C51 is connected to the input pins of all the 74LS574 and 74HC574 with latch characteristics. The selected 74LS574 and 74HC574 read and output new data and wait for new data. In other words, eight signals can be output from the output terminal of one Octal D Flip-Flop.

In addition, the present invention is a model that can visually express the stimulus transmission and the response related to the nervous system through a specific operation as a result of the investigation of a number of foreign cases are not developed at home and abroad, the possibility of foreign export is high, the international competitiveness of technology It is a useful invention that can improve.
