Abstract

The present invention relates to virtual code-based control system, method and program, a control device and a control signal generating means. A control method on the basis of a control signal comprising a virtual code according to an embodiment of the present invention comprises: a control signal receiving step for a control module receiving, from a control signal generating means, a control signal generated by means of combining a plurality of specific codes in accordance with a particular rule; a step for the control module extracting the plurality of specific codes comprised in the virtual code; and a command searching step for the control module searching for a storage location comprising a particular command on the basis of the plurality of specific codes.

Claims

1. A control signal-based control method, the method comprising:

receiving, by a control module, a control signal generated at a specific time point, from a control signal generating means, wherein the control signal includes a specific virtual code and the virtual code is generated by combining a plurality of detailed codes depending on a specific rule;

extracting, by the control module, the plurality of detailed codes included in the virtual code; and

searching, by the control module, for a storage location including a specific command based on the plurality of detailed codes,

wherein the virtual code is generated differently depending on the command at a same time point and is generated differently for each unit count,

wherein the control module is embedded with or installed in a control device and determines a search start point and a search path based on the plurality of detailed codes to search for the storage location when the virtual code normally generated for each unit count is received, and

wherein the unit count is set to a specific time interval so as to be changed as the time interval elapses.

2. The method of claim 1, wherein the control signal generating means includes a virtual code generation function corresponding to each command and transmits a virtual code generated through a virtual code generation function corresponding to a command selected at a specific time point by a user, as the control signal.

3. The method of claim 2, wherein the virtual code generation function includes:

a plurality of detailed code generation functions configured to generate detailed codes, respectively; and

a detailed code combination function configured to combine each detailed code depending on a specific combination rule,

wherein the detailed code generation function applies the combination rule by reflecting a unique value of the control device or a unique value of the control signal generating means, and

wherein the control module includes the detailed code combination function the same as the control signal generating means to extract a plurality of detailed codes using the detailed code combination function.

4. The method of claim 1, further comprising:

synchronizing, by the control module, a unit count in synchronization with the control signal generating means based on time data obtained by a location information obtaining module in the control device.

5. The method of claim 2, wherein the virtual code generation function includes a first code generation function and a second code generation function,

wherein the first code generation function and the second code generation function generate a different code when a corresponding command or unit count is different,

wherein the detailed code includes:

a first code for setting a start point of a storage location search; and

a second code for setting a search path from the start point to the storage location depending on a specific search method, and

wherein the first code and the second code are changed for each unit count.

6. The method of claim 5, wherein, when a storage location search algorithm moves a pointer on a single track based on the first code and the second code, the searching for the storage location including the specific command includes:

moving the pointer to a point on the track corresponding to the first code within the virtual code received from the control signal generating means;

setting a location corresponding to the first code to a search start point and searching for a point matched with a storage location of the command by returning the track by the number of counts corresponding to the second code; and

extracting the command included in a command storage location.

7. The method of claim 6, wherein the control module stores each command in a storage location corresponding to a different initial unit count,

wherein the virtual code is composed of the first code and the second code, which are generated based on a count plus a virtual security code at a time point corresponding to the initial unit count or a command input time point, and

wherein the virtual security code is not separately provided from the control signal generating means to the control module, as a code value of specific digits generated through an OTP function based on a unique value of the control signal generating means or a unique value of the control device,

further comprising:

verifying, by the control module, whether the virtual code is normally generated, by comparing a generation virtual security number, which is calculated based on a time value within a specific range from a time point at which the virtual code is received, with a reception virtual security code extracted from the virtual code.

9. A control program based on a control signal including a virtual code, the program being stored in a medium to be combined with a computer which is hardware and perform the method of claim 1.

8. A control signal-based control method, the method comprising:
