Details of the configuration, method and effects of the program download system according to the present invention will be clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

Hereinafter, the program download system according to the present invention will be described in more detail with reference to the accompanying drawings.

3 is a block diagram of a program download system according to the present invention, FIG. 4 is an explanatory diagram showing data conversion according to the present invention, and FIG. 5 is a block diagram showing a modification of the program download system according to the present invention.

First, as shown in FIG. 3, the program download system 100 according to the present invention includes a host 110, a communication module 120, and a server 140.

The host 110 may generally be a personal computer (PC), is connected to the communication module 120 through a communication cable 130, and delivers a program.

The communication module 120 is mounted on a communication terminal such as a mobile communication terminal or a short range wireless communication terminal to perform wireless communication with an external device. In addition, the communication module 120 is connected to the host 110 through a communication cable 130, and transmits or receives a program through an RS232 communication method.

The server 140 wirelessly communicates with the communication module 120 to transmit a program for downloading to the communication module 120 to the communication module 120 via wireless. At this time, the server 140 and the communication module 120 preferably transmits and receives the predetermined data with each other via a TCP / IP communication network, a mobile communication network or a short-range wireless communication network.

In particular, since the communication module 120 cannot download the program transmitted from the server 140 by itself, the communication module 120 converts the text data into text data and then transfers the text data to the host 110. In this case, the program is preferably made of binary data.

Meanwhile, the reason why the communication module 120 cannot directly download the binary data transmitted from the server 140 is because the communication module 120 has a low storage space, thereby receiving the program of the binary data directly. Since there is no free storage space for download, the program converts the binary data into text data and transmits the program to the host 110 at the same time.

For example, the storage space of the communication module 120 is mainly in the range of 4Mbyte to 5Mbyte and the main use space has a low storage capacity of about 3Mbyte. At this time, the program transmitted from the server 140 is a program to be downloaded to the communication module 120 has a capacity of about 3Mbytes. Accordingly, the communication module 120 cannot directly download a program due to lack of storage space, and converts the program into text data at the same time as the transmission and transmits the program to the host 110.

A method of converting binary data, which is a program, into text data in the communication module 120 will be described with reference to FIG. 4. In this case, it is assumed that the binary data is 8 bits, and the text data is data having 16 bits.

The 8-bit binary data is separated into four bits of upper data H and lower data L, respectively. Then, the upper data H is left shifted and stored in a neighboring 8-bit buffer.

Next, the upper data H and the lower data L are compared with 10, and 55 is added to 10 or more data, and 48 is added to data less than 10. By adding 55 and 48 respectively, data having a value greater than or equal to 10 can be represented by ASCII code values' A to Z 'corresponding to '65 to 90', and data having a value less than 10 is represented by '48'. ASCII code value '0 ~ 9' corresponding to '57' can be expressed.

After converting the separated upper and lower data (H, L) of the binary data to have an ASCII code value, respectively, the upper data (H) stored in an 8-bit upper buffer (H ') and an 8-bit lower buffer (L). By converting the lower data L stored in ') into one data, it is converted into one text data. Accordingly, the text data is preferably an ASCII file having an ASCII code value.

This conversion method is performed in real time while the program of the binary data is transmitted, and the text data, which is blocked and converted into one data, is converted and transferred to the host 110 at the same time.

The reason why the communication module 120 converts the program into text data is that the communication module 120 and the host 110 are connected to each other through a communication cable 130, and the communication cable 130 is RS232. Since the data is transmitted in a communication method, the program is converted into text data having an AT command form.

In particular, the host 110 receives all text data transmitted through the communication module 120 and converts the text data into a program of binary data, and then transfers the text data to the communication module 120 to download the program.

At this time, the method of reconverting the text data in the host 110 to binary data is performed in the reverse order of the method of converting the above-mentioned binary data into text data.

Since the storage space is sufficient in the host 110, the text data transmitted from the communication module 120 is not transferred and converted into binary data at the same time, and the text data corresponding to one program is not converted until all of the text data is transferred. Save it.

Then, the host 110 converts all text data from the communication module 120 to binary data and downloads the program by transferring the restored program to the communication module 120.

As described above, the program download system 100 according to the present invention receives a program from the server 140 through wireless communication in the communication module 120, transfers the transmitted program to the host 110, and then downloads the program. Receive. Accordingly, the wireless download system 100 of the present invention can simplify the download process as it does not need to store the program to be downloaded in advance through the control unit 11 as in the prior art.

In addition, the wireless download system 100 of the present invention can shorten the download time by downloading the program transferred through the communication module 120 directly from the host 110 to the communication module 120.

On the other hand, as shown in Figure 5 showing a modification of the program download system according to the present invention, the download system 200 is composed of a host 210, a plurality of communication modules (220a ~ 220n) and the server 240 .

The host 210 is connected to the first to n th communication modules 220a to 220n through the first to n th communication cables 230a to 230n. Accordingly, the program is received as text data through at least one communication module of the first to n-th communication modules 220a to 220n, and converted into binary data, and then the corresponding communication module or the first to nth communication modules. By transmitting to the communication modules 220a to 220n, programs can be downloaded to the first to n-th communication modules 220a to 220n at the same time.

Hereinafter, the program download method according to the present invention will be described in detail with reference to FIGS. 3 to 5 and FIG. 6 as follows.

6 is a flowchart sequentially showing a program download method according to the present invention.

First, as shown in FIG. 6, the program download method according to the present invention transmits a program from the server 110 to the communication module 120 through wireless communication (S310).

Then, the communication module 120 converts the program transmitted in step S310 into text data (S320). In this case, the program is binary data, and the text data is an ASCII file.

In particular, since the storage space of the communication module 120 is insufficient, the program of the binary data is not directly downloaded, but is converted into text data and transmitted to the host in real time (S330).

A method of converting a program of binary data into text data in step S320 will now be described. In this case, it is assumed that the program of binary data is 8 bits, and the text data is data having 16 bits.

The 8-bit program is divided into upper data and lower data of 4 bits each. The upper data is then left shifted and stored in a neighboring 8-bit buffer.

Next, the upper data H and the lower data L are compared with 10, and 55 is added to 10 or more data, and 48 is added to data less than 10. By adding 55 and 48 respectively, data having a value greater than or equal to 10 can be represented by ASCII code values' A to Z 'corresponding to '65 to 90', and data having a value less than 10 is represented by '48'. ASCII code value '0 ~ 9' corresponding to '57' can be expressed.

After converting the separated upper and lower data (H, L) of the binary data to have an ASCII code value, respectively, the upper data (H) stored in an 8-bit upper buffer (H ') and an 8-bit lower buffer (L). By converting the lower data L stored in ') into one data, it is converted into one text data.

This conversion method is performed in real time while the program of the binary data is transmitted, and the converted text data is transferred to the host 110 at the same time. In this case, it is preferable that the communication module 120 and the host 110 transmit text data through RS232 communication.

After transferring the text data to the host 110, the host 110 restores the program by reconverting the text data into binary data (S340). The method of reconverting the text data into binary data proceeds in the reverse order of the method of converting the binary data into text data.

In this case, the reason why the host 110 converts the text data into binary data is to convert the text data into a program for downloading to the communication module 120.

After converting all the text data into binary data in step S340, the program is downloaded by transferring the converted binary data to the communication module 120 (S350).

Meanwhile, the method for downloading a program to the plurality of communication modules 220a to 220n illustrated in FIG. 5 may include at least one of the first to nth communication modules 220a to 220n through wireless communication at the server 210. The program is transmitted to one communication module, and the communication module converts the received program into text data and transmits the received program to the host 210.

The host 210 converts the received text data into binary data to restore the program, and transfers the restored program to at least one communication module of the first to nth communication modules 220a to 220n. You can download it.

The program download method for downloading a program by the above-described method may simplify the download process by receiving the program of binary data to be downloaded through the communication module 120 without storing the program in the host 110 in advance. It can save time.

Preferred embodiments of the present invention described above are disclosed for the purpose of illustration, and various substitutions, modifications, and changes within the scope without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains.
