Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Referring to FIG. 1, a real-time data transmission / reception system 100 includes a first device 110, a second device 120, and a real-time data transmission / reception device 130.

The first device 110 and the second device 120 are devices that transmit and receive data to each other in real time. In this embodiment, at least one of the first device 110 and the second device 120 is equipped with a non-real-time operating system.

In the following description, the first device 110 is defined as a system (e.g., Windows System) equipped with a non-real time OS and the second device 120 is installed with a real time OS It is defined as a system (eg Real Time System).

The real-time data transmission / reception device 130 is a modular (hardware) real-time data transmission / reception device and includes an MCU 131, a power 132, a memory 133 and a real-time processor 134 do. Also, the real-time data transmission / reception device 130 includes a first port 135, a second port 136, and a third port 137 for relaying data between the first device 110 and the second device 120 do. The real-time data transmission / reception device 130 may be implemented as a PCB.

The internal configuration of the above-mentioned real-time data transmission / reception device 130 will be described in detail with reference to FIG.

2 is an internal configuration diagram of a real-time data transmitting and receiving apparatus according to an embodiment of the present invention.

The first port 135 is a port for performing serial communication with the first device 110. The first port 135 is a serial port for system setup, and may be implemented as a USB port.

The second port 136 is a port for performing Ethernet communication with the first device 110. The second port 136 is a LAN port connectable to a general PC (i.e., the first device 110) having a window, and may be implemented as an Ethernet port.

The third port 137 is a port for performing Ethernet communication with the second device 120. The third port 137 is a LAN port connectable with the remote device (i.e., the second device 120) requiring real-time transmission, and may be implemented as an Ethernet port.

The power supply unit 132 supplies power to the respective components constituting the real-time data transmission / reception device 130.

The MCU 131 controls the overall operation of each component constituting the real-time data transmitting / receiving device 130. The MCU 131 can control the serial communication with the first device 110 through the first port 135 and the address information and data input through the first port 135 in real time To the processor 134. < RTI ID = 0.0 >

The memory unit 133 stores information acquired / processed by the respective constituent elements of the real-time data transmission / reception device 130. [ The memory unit 133 may store address information, data, and the like transmitted to the real-time processor 134 under the control of the MCU 131.

The real-time processor 134 controls data transmission between the first device 110 and the second device 120 in real time. The real time processor 134 may perform an algorithm for real time data reception and buffering, a real time transmission algorithm, a transmission period conversion algorithm, an Ethernet header information conversion algorithm, and the like using a real time scheduler. Here, the real-time transmission algorithm means an algorithm for transmitting the aperiodic data in real time, and the transmission period conversion algorithm means an algorithm for transmitting real-time data to the aperiodic system.

Next, an operation method of the real-time data transmission / reception device 130 will be described. 3 is a flowchart illustrating a method of operating a real-time data transmitting / receiving apparatus according to an embodiment of the present invention.

Hereinafter, the operation principle when data is periodically transmitted in an aperiodic system (ex. Windows system) will be described with reference to FIG. In the embodiment according to FIG. 3, the first device 110 is a non-periodic system in which a non-real-time operating system is installed, that is, a Windows system, and the second device 120 is a real-time system.

First, the first device 110 and the second device 120 set the real-time data transmission / reception device 130 to be recognized as an actual communication target (S210). To this end, the MCU 131 performs the following functions.

(1) The MCU 131 acquires the address information (e.g., 192.168.100.100) of the first device 110 using the first port 135. [ The address information of the first device 110 acquired by the MCU 131 may be, for example, an IP address.

(2) The MCU 131 also acquires address information (e.g., 192.168.100.200) of the second device 120 using the first port 135. [ In the present embodiment, the MCU 131 is not limited to use the first port 135 when acquiring the address information of the second device 120, and it is also possible to use the third port 137 or wireless communication Do. The address information of the second device 120 may be stored in the memory unit 133 in advance and the MCU 131 may read the address information of the second device 120 from the memory unit 133. [

Then, it is set to recognize that the first device 110 and the second device 120 are directly connected to each other using the real-time data transmission / reception device 130 (S220). The following functions are performed for this purpose.

(1) The LAN ports 136 and 137 of both terminals are connected to the first device 110 and the second device 120, respectively. First, the LAN system of the window system is connected to the LAN port # 2 (that is, the real time data transmitting / receiving apparatus 130 is connected to the first device 110 by using the second port 136) (That is, connects the real-time data transmission / reception device 130 and the second device 120 using the third port 137).

(2) The address information of the second port 136 is set to be the same as the address information of the second device 120, and the address information of the third port 137 is set to be the same as the address information of the first device 110 . So that when the data acquired / generated by the first device 110 is relayed to the second device 120, the first device 110 is recognized as directly communicating with the second device 120.

Then, when the first device 110 transmits the data aperiodically through the second port 136 (S230), the real-time processor 134 determines whether or not the data is available for temporary storage (S240 ).

If it is determined that the received data is as large as possible for temporary storage, the real-time processor 134 temporarily stores the data in the form of a message queue. Then, the real-time processor 134 converts the header information of the packet containing data after buffering for a predetermined time (e.g., 0.8 ms to 1.2 ms) (S250). The reason that the real-time processor 134 converts the header information of the packet is to set the second device 120 as if the data was received from the first device 110. [ Thereafter, the real-time processor 134 transmits the temporarily stored data to the second device 120 through the real-time processing (S260).

On the other hand, if it is determined that the received data is a size that is not possible for temporary storage, the real-time processor 134 stores the whole data in the memory unit 133. [ Thereafter, the real time processor 134 divides and extracts data from the memory unit 133 every determined period (S270). Thereafter, the real-time processor 134 converts the header information of the packet containing the data (S250). As described above, the reason why the real-time processor 134 converts the header information of the packet is to set the second device 120 as if the first device 110 received the data. Thereafter, the real-time processor 134 transmits the temporarily stored data to the second device 120 through the real-time processing (S260).

4 is a flowchart illustrating a method of operating a real-time data transmitting / receiving apparatus according to an embodiment of the present invention.

The operation principle of storing data in an aperiodic system when data is periodically transmitted from a real time system to an irregular system (Windows system) will be described with reference to FIG. In the embodiment according to FIG. 4, the first device 110 is an aperiodic system in which a non-real-time operating system is installed, that is, a Windows system, and the second device 120 is a real-time system.

The real time data transmission / reception device 130 stores the data received in real time from the second device 120 in the memory unit 133, because the first device 110 is missed when receiving quick periodic input data due to its internal scheduling characteristic And performs buffering.

In addition, the real-time data transmission / reception device 130 maximizes the transmission period so that the first device 110 can easily perform the data reception process. At this time, the real-time data transmission / reception device 130 can reconfigure the packet by combining the buffering data within the Ethernet MTU (Maximum Transmission Unit) size of 1500 bytes.

For example, when the second device 120 transmits data by 100 bytes every 1 ms, the real-time data transmission / reception device 130 changes the period to 2 ms, reconfigures the data to 200 bytes, and transmits the data to the first device 110. Here, 200 bytes is a value obtained from 1 ms: 100 bytes = 2 ms: x bytes.

According to the above, the first device 110 needs to process a process of dividing the reconfigured packet into the original packet instead of receiving the slow periodic packet slowly. If the user uses the segmented packet data, The same effect as that of FIG.

Reference is now made to Fig.

First, the first device 110 and the second device 120 set the real-time data transmission / reception device 130 to be recognized as an actual communication target (S310). To this end, the MCU 131 performs the following functions.

(1) The MCU 131 acquires the address information (e.g., 192.168.100.100) of the first device 110 using the first port 135. [ The address information of the first device 110 acquired by the MCU 131 may be, for example, an IP address.

(2) The MCU 131 also acquires address information (e.g., 192.168.100.200) of the second device 120 using the first port 135. [ In the present embodiment, the MCU 131 is not limited to use the first port 135 when acquiring the address information of the second device 120, and it is also possible to use the third port 137 or wireless communication Do. The address information of the second device 120 may be stored in the memory unit 133 in advance and the MCU 131 may read the address information of the second device 120 from the memory unit 133. [

Then, the first device 110 and the second device 120 are recognized as if they are directly connected by using the real-time data transmission / reception device 130 (S320). The following functions are performed for this purpose.

(1) The LAN ports 136 and 137 of both terminals are connected to the first device 110 and the second device 120, respectively. First, the LAN system of the window system is connected to the LAN port # 2 (that is, the real time data transmitting / receiving apparatus 130 is connected to the first device 110 by using the second port 136) (That is, connects the real-time data transmission / reception device 130 and the second device 120 using the third port 137).

(2) The address information of the second port 136 is set to be the same as the address information of the second device 120, and the address information of the third port 137 is set to be the same as the address information of the first device 110 . So that when the data acquired / generated by the first device 110 is relayed to the second device 120, the first device 110 is recognized as directly communicating with the second device 120.

Then, the second device 120 periodically transmits the data through the third port 137 (S330), and the real time processor 134 stores the data in the memory unit 133. [ Thereafter, the real-time processor 134 divides and extracts data from the memory unit 133 (S340).

Thereafter, the real-time processor 134 transforms the transmission period so that the first device 110 can process it (S350), and combines the data extracted from the memory unit 133 in proportion to the transmission period (S360). At this time, the real-time processor 134 may combine the data for a period to be increased.

Thereafter, the real-time processor 134 converts the header information of the packet containing the data (S370). The reason that the real-time processor 134 converts the header information of the packet is to set the first device 110 as if the data was received from the second device 120. [ The real-time processor 134 then transmits the data to the first device 110 through real-time processing (S380).

The present invention described above can be applied when periodic data transmission is guaranteed within several milliseconds in an environment such as a general PC operating in a window. In addition, the present invention is also applicable to a case where data is periodically received within a few milliseconds in an environment such as a general PC operating in a window, without fail to store the data.

The present invention described above can be applied to a missile. The inertial navigation system mounted on the missile must be subjected to an alignment process before the launch, in which case the alignment data must be periodically transmitted to the inertial navigation system. For this function, it is necessary to construct a system using a real-time OS or a kernel, and the present invention can be used in place of the system described above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention has been described with reference to Figs. Best Mode for Carrying Out the Invention Hereinafter, preferred forms of the present invention that can be inferred from the above embodiment will be described.

5 is a conceptual diagram schematically showing a real-time data transmission / reception control apparatus according to a preferred embodiment of the present invention.

5, the real-time data transmission / reception control apparatus 400 includes an identification information acquisition unit 410, a data acquisition unit 420, a data processing unit 430, a power supply unit 440, and a main control unit 450.

The power supply unit 440 performs a function of supplying power to each configuration of the real-time data transmission / reception control device 400. [

The main control unit 450 controls the overall operation of each configuration of the real-time data transmission / reception control device 400. [

The identification information acquiring unit 410 acquires the first identification information of the first device and the second identification information of the second device. The identification information obtaining unit 410 may obtain the first identification information and the second identification information using serial communication.

The data acquisition unit 420 acquires data in real time based on the first identification information when data is input to the first device or when data is generated by the first device. The data acquisition unit 420 may use the second identification information as its identification information when acquiring data from the first device.

The data processing unit 430 performs a function of transmitting data to the second device in real time based on the second identification information. The data processor 430 may use the first identification information as its identification information when transmitting data to the second device.

The data acquisition unit 420 and the data processing unit 430 may relay data from the first device to the second device using Ethernet communication. The data acquisition unit 420 may acquire data from the first device using the Ethernet communication and the data processing unit 430 may transmit data to the second device using the Ethernet communication.

The real-time data transmission / reception control apparatus 400 can operate when the first device is a device not equipped with an RTOS (Real Time Operating System). In particular, the real-time data transmission / reception control apparatus 400 can operate when the second device transmits data to the first device in real time at a high speed.

Meanwhile, when data is input to the second device or data is generated by the second device, the data acquisition unit 420 acquires data in real time based on the second identification information, and the data processing unit 430 acquires first identification information It is also possible to transmit data to the first device on a real-time basis.

In this case, the data processing unit 430 may transmit data to the first device using a period longer than the reference period when the first device is a device that does not include the RTOS. The reference period means a period in which the real-time data transmission / reception control device 400 transmits data to the first device. In this embodiment, the reference period may be, for example, 1 ms. In this case, the real-time data transmission / reception control apparatus 400 may transmit data to the second device every 1 ms.

In addition, the data processor 430 may transmit a larger amount of data to the first device when the data is transmitted using the period longer than the reference period. The reference amount refers to the amount of data that the real-time data transmission / reception control device 400 can transmit to the first device at one time. In this embodiment, the reference amount may be 100 bytes.

The data processing unit 430 may determine the amount of data to be transmitted based on the extended period. The data processing unit 430 can determine the amount of data to be transmitted in proportion to the extended period. For example, assume that the reference period is 1 ms and the reference amount is 100 bytes. In this case, if the extended period (i.e., the period longer than the reference period) is 2 ms, the data processing unit 430 can determine the amount of data to be transmitted in proportion to 200 bytes.

Meanwhile, the real-time data transmission / reception control apparatus 400 may further include a first device monitoring unit 460 and a first device determination unit 470.

The first device monitoring unit 460 performs a function of determining whether the power of the first device is ON.

The first device determination unit 470 determines whether there is data input to the first device if the first device monitoring unit 460 determines that the power of the first device is turned on. The first device determination unit 470 may also determine whether there is data generated by the first device.

If the first device monitoring unit 460 determines that the first device is powered on by the first device monitoring unit 460, the first device determining unit 470 transmits a query message to the first device at predetermined time intervals, Based on the response message of the first device, whether there is data input to the first device or whether there is data generated by the first device. The inquiry message includes inquiring whether there is data input to the first device or whether there is data generated by the first device. And a response message to this may be prepared and provided by a person connected to the first device.

Next, an operation method of the real-time data transmission / reception control device 400 will be described. 6 is a flowchart schematically illustrating a method for controlling real-time data transmission / reception according to a preferred embodiment of the present invention.

First, the identification information obtaining unit 410 obtains the first identification information of the first device and the second identification information of the second device (S510).

Thereafter, when data is input to the first device or data is generated by the first device, the data acquisition unit 420 acquires data in real time based on the first identification information (S520).

Thereafter, the data processing unit 430 transmits the data to the second device in real time based on the second identification information (S530).

Thereafter, the display control unit (not shown) displays whether data is successfully transmitted in real time (S540).
