According to the present invention, the user can understand the basic concept of the logic circuit by connecting various physical sensors and operation devices to the logic block according to the present invention.

In other words, in the past, the user could make various application devices by a combination of the physical sensors and the operation devices. However, in order to specifically satisfy the conditions of the various physical sensors and the operation conditions of the operation devices other than the one- It was necessary to design through the programming knowledge of.

In addition, the logic block according to the present invention checks whether or not the input control unit inputs the input device, that is, the physical sensors, and if the physical sensor is not operating normally or the connection is not established, (Or fixed to an input value of 1 in the case of an AND operation and fixed to an input value of 0 in the case of an OR operation) in accordance with the setting reference of the computing means , It is possible to prevent an input connection without connection from affecting the calculation result. In other words, if a logic block is manufactured in a form in which an existing semiconductor chip is mounted, it is necessary to utilize all of the input connection ports. However, since the logic block operates in software in the present invention, Can be done correctly.

FIG. 1 is a perspective view of a logic block according to an embodiment of the present invention, FIG. 2 is a perspective view of the logic block shown in FIG. 1, and FIG. Fig. 4 is a block diagram for explaining the logical block shown in Figs. 1 and 2. Fig.

1 to 4, a logic block 10 according to an embodiment of the present invention includes a case 11, a logic select button 13, a display 14, a substrate 17, Output connection ports 16a, 16b, and 16c, output inversion buttons 16ai, 16bi, and 16ci, and a processor 18, as shown in FIG.

The cases 11 and 12 forming the outer appearance of the logic block 10 may be made in the form of a toy block, but the form thereof is not limited. Other components of the logic block 10 are mounted inside the cases 11 and 12 including the front case 11 and the rear case 12 and the input connection ports 15a, 15b and 15c and the output connection ports 16a, 16b, and 16c, output inversion buttons 16ai, 16bi, and 16ci, and the display unit 14 are exposed.

The logical selection button 13 is an input means for allowing the user to input what logical operation the logical block 10 is to perform. The logic selection button 13 may be formed in the form of a button as shown in the figure, or may be fabricated in the form of a switch or a dial. That is, the user can set the logic block 10 to operate as any one of AND gate, OR gate, NOT gate, NAND gate, NOR gate, XAND gate and XOR gate through the operation of the logic selection button 13. [

The display unit 14 is a means for indicating what sorting criterion is currently set in accordance with the input of the logical selection button 13, that is, which logic device 10 performs the function of which of the various logic devices. The display unit 14 may be formed as a display mounted on a part of the case 11 or 12 and may be implemented as an LED lamp mounted in the logic selection button 13. [ That is, when the logic selection button 13 is pressed once, a red color lamp is inputted to the logic selection button 13 to inform that it is an AND gate state, and when it is pressed again, a blue color lamp is inputted, It is.

The board 17 is provided for mounting the input connection ports 15a, 15b and 15c, the output connection ports 16a, 16b and 16c and the processor 18. The input connection ports 15a, 15b and 15c are exposed on the left side of the front case 11 and the output connection ports 16a, 16b and 16c are exposed on the right side when the logic block 10 is viewed from the front. The connection ports 15a, 15b, 15c, 16a, 16b, and 16c are provided on the substrate 17. [

A physical sensor for outputting a predetermined signal is connected to the input connection ports 15a, 15b and 15c when a specific physical condition is reached, and various operation devices are connected to the output connection ports 16a, 16b and 16c. For example, the physical sensors connected to the input connection ports 15a, 15b and 15c may be a sound pressure sensor, a distance sensor, a lightness sensor, a humidity sensor, a temperature sensor, , A display, and the like. In addition, there are many applications of physical sensors and operation devices.

15b, 15c, 16a, 16b, and 16c, the C-type USB can be connected to the input connection ports 15a, 15b, 15c and the output connection ports 16a, 16b, 16c may be variously modified. In addition, the physical sensors and the operation devices are not necessarily connected to the input connection ports 15a, 15b, and 15c and the output connection ports 16a, 16b, and 16c using cables and connection terminals, Lt; / RTI > Only a Bluetooth dongle (not shown) is connected to the input connection ports 15a, 15b and 15c and the output connection ports 16a, 16b and 16c and receives a signal from the physical sensor via the dongle to input a value, Lt; / RTI > to the operating device.

The output reversal buttons 16ai, 16bi and 16ci are provided near the output connection ports 16a, 16b and 16c and are provided for inverting output values of the output connection ports 16a, 16b and 16c. That is, when the inputs of the input ports 15a, 15b and 15c are all 1 (High, that is, a voltage exceeding a threshold value or a pulse signal satisfying a specific condition) when the logic block 10 is basically operated as an AND gate It is normal that all the values output from the output connection ports 16a, 16b and 16c are 1 (a set high voltage or a predetermined pulse signal). However, in the specific output connection ports 16a, 16b and 16c, , A set low voltage or inverted pulse signal) can be output.

For example, if the user presses the second output reversal button 16bi, 1 is output in the first output connection port 16a and the third output connection port 16c, and 0 is output in the second output connection port 16b. In this case, substantially only the first output connection port 16a and the third output connection port 16c are used as the AND gate, and the second output connection port 16b is used as the NAND gate.

The processor 18 performs a logic operation using the values input through the input connection ports 15a, 15b and 15c to output logical operation result values (basically, 1 or 0) to the output connection ports 16a, 16b and 16c, A set high voltage, a set low voltage, a set pulse signal, or an inverted pulse signal). The processor 18 includes a display unit control means 18a, a logic setting means 18b, an arithmetic means 18c, an input control means 18d and an output control means 18e.

The display unit control means 18a is provided for controlling the display unit 14 so as to inform the logical operation standard of the calculation means 18c according to the input of the logical selection button 13. [ For example, if the logic selecting button 13 is pressed once and the calculating means 18c is set to perform the function of the AND gate, the display controlling means 18a causes the red selecting lamp 13 to emit a red lamp, Or to display the character "AND" on the display unit 14 in display form.

The logic setting means 18b is provided for setting or resetting the logical operation standard of the calculation means 18c in accordance with the input of the logical selection button 13. [ For example, if the user has pressed the logical select button 13 once to use the logical block 10 as an AND gate, the logic setting means 18b sets the operation means 18c to perform an AND operation, If the logic select button 13 is pressed once more for use as a gate, the logic setting means 18b is to reset the arithmetic means 18c to perform an OR operation.

The calculation means 18c is provided for performing the calculation according to the reference set by the logic setting means 18b using the values inputted through the input ports 15a, 15b and 15c and outputting the resultant value. That is, the calculation means 18c serves as a practical logic element. This means that the specific function is not fixed in the form of an existing semiconductor chip but operates according to a preset program. The calculation function is changed.

The input control means 18d is provided for inputting the respective input values inputted through the input connection ports 15a, 15b and 15c to the calculation means 18c. At this time, the input control means 18d checks whether the physical connection of the input connection ports 15a, 15b and 15c is connected. If there is no connection, the values of the input connection ports 15a, 15b and 15c are inputted to the calculation means 18c Or the calculation means 18c processes the specific input value to be automatically inputted according to the currently set logic reference. The description of the input control means 18d will be described later.

The output control means 18e processes the resultant value output from the calculation means 18c so as to be output through the output connection ports 16a, 16b and 16c. When there is input of the output inversion buttons 16ai, 16bi and 16ci, The output values of the output connection ports 16a, 16b, and 16c where the inputs of the output inversion buttons 16ai, 16bi, and 16ci are generated are inverted and processed.

For example, if the calculation means 18c is set to the OR gate by the input of the logic selection button 13 and the third output inversion button 16ci is in the depressed state, any one of the input connection ports 15a, 15b and 15c 1 is input, the output control means 18e outputs the result of 1, which is the calculation result of the calculation means 18c, to the output connection ports 16a, 16b and 16c, and the first output connection port 16a and the second output A result value of 1 is output only to the connection port 16b and a result value of 0 is output to the third output connection port 16c to which the third output inversion button 16ci is pushed. In this case, the first output connection port 16a and the second output connection port 16b operate as an OR gate, and the third output connection port 16c operates as a NOR gate.

The output control means 18e recognizes the operation devices connected to the output connection ports 16a, 16b and 16c in the same manner as the input control means 18d and recognizes the connected operation devices. If there is no connection, 16b, and 16c side, the result value may not be output. This will be discussed later.

The logic block 10 according to the embodiment of the present invention described above will be further described with reference to the application examples shown in Figs.

FIG. 5 is a diagram for explaining a first application example of the logic block 10 shown in FIG. 1 to FIG. 5 shows that the logic block 10 is applied to the robot toy. The sound-pressure sensor 21 is connected to the first input connection port 15a and the sound-pressure sensor 21 is connected to the second input connection port 15b. A sensor 22 is connected to the first output port 16a and a light emitting lamp 31 is connected to the first output port 16a and a driving motor 32 is connected to the second output port 16b.

In this state, if the user presses the logical selection button 13 to set the calculation means 18c to operate as an AND gate, the logic setting means 18b sets the logical calculation basis of the calculation means 18c to an AND operation, The display unit control means 18a causes the display unit 14 to indicate that it is operating as an AND gate.

Let's assume that the user shouted 'forward' by voice command. In this case, if the sound pressure sensor 21 recognizes a sound of a certain sound pressure or more, it will output a set High signal, so that 1 will be inputted to the first input connection port 15a. However, since the operation unit 18c of the logic block 10 performs the AND operation, it does not output a separate output value only by inputting the High signal of the first input port 15a. That is, the input value through the second input port 15b must be confirmed before the calculation can be performed, and the distance sensor 22 is connected to the second input port 15b. The distance sensor 22 is designed to check whether there is an obstacle within a predetermined distance, to output a high signal when there is no obstacle (a certain distance or more), or to output a low signal when there is an obstacle .

Therefore, when the output of the distance sensor 22 is high because there is no obstacle, 1 will be inputted to the second input terminal 15b, so that the calculation means 18c can calculate the output current of the first input terminal 15a, The output control means 18e outputs all of the output connection ports 16a, 16b, 16c (16a, 16b, 16c) as long as there is no input of another output inversion button (A voltage or a pulse signal of a predetermined level or higher) is outputted to the light emitting lamp 31 and the traveling motor 32 so that the light emitting lamp 31 and the traveling motor 32 are operated.

That is, the robot toy is informed that the robot toy is running by the operation of the light emission lamp 31, and the robot toy can start traveling without obstacle by the operation of the travel motor 32.

In the first application example shown in FIG. 5, the robot toy is operated according to a voice command of the user. By allowing the logic block 10 according to the embodiment of the present invention to perform the role of the AND gate, This is because it is possible to operate only when the condition of no obstacle is satisfied.

Here, no physical sensor is connected to the third input connection port 15c. In this case, the calculation means 18c should not recognize the input of the third input connection port 15c as 0 (low). That is, if the calculation means 18c recognizes the input of the third input port 15c as 0 while performing the AND operation, even if 1 is input through the first and second input ports 15a and 15b, 0 < / RTI > The role of the input control means 18d is needed for the case where there is no connection of the specific input connection ports 15a, 15b, 15c.

4, the input control means 18d inputs the values input through the input connection ports 15a, 15b and 15c to the arithmetic means 18c, respectively, so that the logic operation is performed. The input ports 15a, 15b, and 15c are connected to each other, and the physical sensors are connected to each other. If there is no connection, specific control operations are performed so that there is no error in the logic operation.

That is, the input control unit 18d transmits the specific signal to the connected physical sensor side, receives the response, and determines whether the physical sensor is connected or not. For example, when the physical sensor and the logical block 10 are connected and a specific protocol is set, the connection can be confirmed using a PING (Packet Internet Grouper). That is, the input control means 18d periodically transmits a specific request signal (request) to the physical sensors connected to the input connection ports 15a, 15b and 15c, and when the response signal (reply) is received, Depending on what you have, you can check which physical sensors are connected and are operating normally. Of course, if there is no response signal, it can be understood that no physical sensor is connected to the input connection ports 15a, 15b, 15c, or even if it is connected, it is not normal operation.

If it is confirmed that the physical sensors are not connected to the specific input connection ports 15a, 15b and 15c by the request / response signal of the input control means 18d, the calculation means 18c calculates the physical According to the sensor connection state information, the input values of the input connection ports 15a, 15b, and 15c without connection are excluded, and logic processing is performed. For example, if the input control means 18d confirms that the physical sensor is connected to the first input port 15a and the second input port 15b as shown in FIG. 5 but no connection is made to the third input port 15c, The calculation means 18c performs logical operation using only the input values of the first input port 15a and the second input port 15b without the value of the third input port 15c.

Of course, a pull-up or a pull-down structure may be applied to the input control means 18d in a circuit so that the input connection ports 15a, 15b, 15c may be fixed. For example, if it is confirmed that the physical sensors are connected to the first and second input ports 15a and 15b as shown in FIG. 5, the input control unit 18d determines that the inputs of the first and second input ports 15a and 15b are physical sensors So that the input value sent from the input side is transmitted to the calculation means 18c as it is. On the other hand, with respect to the third input port 15c having no physical sensor connection, 1 (Hight) or 0 (low) is fixedly input depending on what logic operation standard is set by the calculation means 18c.

If the logic operation basis of the calculation means 18c is an AND operation, the input control means 18d pulls up the input of the third input port 15c, which has no connection, so that it always becomes 1 (Hight) So that the input value of the input connection port 15c has no influence on the calculation of the calculation means 18c.

On the other hand, if the logic operation basis of the calculation means 18c is an OR operation, the input control means 18d pulls-down the input of the third input port 15c, which has no connection, So that the input value of the input connection port 15c does not have any influence on the calculation of the calculation means 18c.

The output control means 18e also performs the functions described above and controls the types of operation devices connected to the output connection ports 16a, 16b and 16c by using the ping in a similar manner to the input control means 18d, 16b and 16c which are not connected to any operation device, the output control means 18e can output the resultant output values 16a, 16b and 16c to the output connection ports 16a, 16b and 16c without connection, Can not be output.

FIG. 6 is a diagram for explaining a second application example of the logic block 10 shown in FIG. 1 to FIG. 6 is an example of utilizing the logic block 10 for a birthday event. The distance sensor 41 is connected to the first input connection port 15a and the distance sensor 41 is connected to the second input connection port 15b. A sound pressure sensor 42 is connected to the first input connection port 15a and an illuminance sensor 43 is connected to the third input connection port 15c. An LED 51 is connected to the first output connection port 16a and an LED candle 52 is connected to the second output connection port 16b and a display 53 such as a TV is connected to the third output connection port 16c ) Are connected.

In this state, if the user presses the logical selection button 13 to set the calculation means 18c to operate as an OR gate, the logic setting means 18b sets the logical calculation basis of the calculation means 18c to an OR operation, The display unit control means 18a causes the display unit 14 to indicate that it is operating as an OR gate.

In the example of Fig. 6, the birthday celebration event is automatically progressed when the hero having arrived on the birthday enters the house. In order to grasp the incoming house, only one of the three conditions is satisfied.

That is, it is confirmed that the main character opens the door through the distance sensor 41 provided near the entrance, or the sound of the door is opened or closed through the sound pressure sensor 42, A high signal is output through the output connection ports 16a, 16b, and 16c so that the audio 51 is reproduced to reproduce the birthday song, and the LED candle 52 is reproduced So that the cake is illuminated, and the display 53 is operated to reproduce a celebration image prepared in advance. Although the operation device such as the audio 51, the LED candle light 52, and the display 53 are directly connected to the output connection ports 16a, 16b, and 16c in the embodiment of FIG. 6, A switch for operating the device, a remote control, or a smart phone equipped with an app capable of operating each device in a batch.

In the examples of FIGS. 5 and 6, an example of an application device that allows a specific operation to be reproduced when a specific condition is satisfied through an AND operation and an OR operation using one logical block 10 has been described. However, It is also possible to design the conditional statements used in actual programming to be visually confirmed by connecting the logical block 10 of the physical block 10 with a plurality of physical sensors and operation devices.

For example, in the example of FIG. 5, a counter (not shown) may be connected between the third input connection port 15c and the third output connection port 16c which are not connected to the physical sensor or the operation device. This counter always outputs a high signal and inputs it to the third input connection port 15c. If a high signal starts to be output from the third output connection port 16c, the counter starts counting. If 10 seconds have elapsed, Output.

That is, when it is confirmed that the user's voice command is inputted and there is no obstacle and the robot toy starts running, the counter counts 10 seconds and inputs a low signal to the third input port 15c, To stop it. Of course, the types of input / output signals of the counter and the counting time can be changed by the user. The counter is an example, but if such an operation device is applied, the logical block according to the embodiment of the present invention can visually express conditional statements such as IF and WHILE by applying it to actual cases.

7 is a diagram for explaining a third application example of a logical block according to an embodiment of the present invention. That is, it is an example of designing an application device using several logic blocks shown in FIG. 1 to FIG.

In the example shown in FIG. 7, the application apparatus is designed using three logical blocks 61, 62, 63, four physical sensors 64, 65, 66, 67 and one operation device 68. The first logical block 61 and the third logical block 63 are set to perform an AND operation and the second logical block 62 is set to perform an OR operation.

The first physical block 64 and the second physical block 65 are connected to the input side of the first logical block 61 and the third physical block 66 and the fourth physical block 65 are connected to the input side. A sensor 67 is connected to the input side and a first operating device 68 is connected to the output side of the third logic block 63. It can also be confirmed that the output of the first logic block 61 and the output of the second logic block 62 are connected to the input side of the third logic block 63.

In the third application example shown in FIG. 7, instead of operating the operation device using only the logical operation by the signal of the physical sensor connected to one logical block, So that the operation is activated.

For example, the first physical sensor 64 is a temperature sensor, the second physical sensor 65 is a sensor for confirming whether the window is closed, the third physical sensor 66 is a remote controller for activating the air conditioner, Let the physical sensor 67 be a sound pressure sensor that is recognized by the voice command of the user, and the first operating device 68 is assumed to be an air conditioner.

Basically, the air conditioner operates when the command input of the remote controller or the voice command of the user is inputted. However, if an application device constituting a predetermined logic circuit is designed using a plurality of logic blocks 61, 62, and 63 as shown in FIG. 7, the air conditioner is operated by a complex element.

That is, when the operation command of the remote controller is inputted through the third physical sensor 66 or the voice command is inputted through the fourth physical sensor 67, the second logic block 62 outputs the High signal. However, the High signal of the second logic block 62 is only one input of the third logic block 63. [ Accordingly, the third logic block 63 can not operate the air conditioner until it receives the High signal from the first logic block 61, without outputting the High signal to immediately activate the air conditioner as the first operating device 68 .

In the first logical block 61, an AND operation is being performed. The condition that the room temperature is equal to or higher than the predetermined temperature is satisfied through the first physical sensor 64 connected to the first logical block 61 and the window is confirmed to be closed through the second physical sensor 65 The first logic block 61 outputs a high signal to operate the air conditioner.

8 is a diagram for explaining a fourth application example of a logical block according to an embodiment of the present invention. That is, an example of a coding application using a plurality of logical blocks 71, 72, 73, and 74 is described below.

The fourth logical block 71, the fifth logical block 72, the sixth logical block 73 and the seventh logical block 74 are all set to perform the AND operation and the fourth through sixth logical blocks 71, 72 and 73, two physical sensors are connected to the input side, respectively. The output terminals of the seventh logic block 74 are connected to the remaining input terminals of the fourth to sixth logic blocks 71, 72, and 73.

In this case, the fourth to sixth logical blocks 71, 72 and 73 basically operate by the signals of the physical sensors connected to the respective logical blocks 71, 72 and 73, ). ≪ / RTI >

That is, when the output value of the seventh logical block 74 is 1 (High), the fourth to sixth logical blocks 71, 72 and 73 logically operate the signal outputs of the independently connected physical sensors, Devices can be played back.

On the other hand, if the output value of the seventh logic block 74 is 0 (low), the fourth through sixth logic blocks 71, 72, and 73 always output 0 (low) Value is output. That is, in the fourth application example shown in Fig. 8, the operation of the fourth to sixth logic blocks 71, 72, 73, or the operation devices connected to the fourth to sixth logic blocks 71, And can be collectively turned on / off through the logic block 74. [

As described in the application example described with reference to FIGS. 7 to 8, in the present invention, coding of complex conditions can be easily implemented by connecting a plurality of logical blocks to each other. That is, the coding process can be designed as a practical application device through a block-type connection, rather than being implemented in a programming language or using a semiconductor chip and a substrate, so that the logic circuit can be visually and interestingly learned.

As described above in detail, according to the present invention, a user can understand various basic physical circuit concepts and logic circuits by connecting various physical sensors and operation devices to the logic block 10 according to the present invention.

In other words, in the past, the user could make various application devices by a combination of the physical sensors and the operation devices. However, in order to specifically satisfy the conditions of the various physical sensors and the operation conditions of the operation devices other than the one- It was necessary to design through the programming knowledge of.

However, if the logic block 10 according to the present invention is used, various physical sensors and operation devices may be connected to the logical block 10 according to the user's intention, and logical AND selection buttons 13, , NOR, XAND, XOR, and the like, it is possible to complete an application device that satisfies conditional statements simply and thereby, the concept of the logic circuit can be learned easily and in an interesting manner.

The logical block 10 according to the present invention not only simplifies the connection of the physical sensor or the operation device but also allows the calculation standard to be reset according to the user command so that even if a large number of logical elements are not purchased, It is possible to complete a complicated logic circuit by using the output inverting button 10, and in particular, one logical block 10 can perform AND and NAND operations simultaneously (or simultaneously perform an OR operation and a NOR operation) The range is broader.

In addition, the logic block 10 according to the present invention confirms whether the input control means 18d is connected to the input ports 15a, 15b and 15c, that is, the physical sensors, If the sensor is not operating normally, the calculation means 18c may be configured not to use the values of the corresponding input connection ports 15a, 15b and 15c without connection, It is possible to prevent the input connection ports 15a, 15b, 15c having no connection from affecting the operation result by fixing the input values to be fixed (fixed to an input value of 1 in the case of the AND operation and fixed to 0 in the case of the OR operation) have. In other words, if a logic block is manufactured by mounting an existing semiconductor chip, it is necessary to use all of the input connection ports. However, since the logic block 10 operates in software in the present invention, the specific input connection ports 15a, 15b, So that the logic operation can be automatically performed even if there is no connection between the memory cells 15a and 15c.

In the above description, only the logic block 10 in the toy block form has been shown and described, but the logic block 10 according to the present invention is not necessarily applied to the learning toy block. For example, if the logic block 10 according to the present invention, to which a physical sensor and an operation device can be connected and performs a set logical operation, can be modularized into various forms and mounted on an industrial robot or a domestic robot, The user can connect the various physical sensors and the operation device to set the operation standard according to the need, and the use range can be further expanded.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
