As shown in FIG. 2, the program RAM 13 of the terminal 1 stores processing programs in block (1) and block (2).
), block (3), block (4), block (5)
,... are divided into multiple blocks and stored.

Further, as shown in FIG. 3, the program block information table 15 stores block information consisting of a block number a1, a version number b1, a program storage start address C1, a program length in the block d1, and a program checksum e1. has been done. This block information is used to parse or recognize the processing program for each block in the program RAM 13, and corresponds to each block data in the program RAM 13.

As shown in FIG. 4, the terminal program block information area 242 of the center machine 2 includes a block number a2, a version number b2, a program storage start address C2, an in-block program length d2, and a program checksum e2. m number of pieces of block information of 1 are saved, and a program change flag area F is provided corresponding to each piece of block information.

The CPU 21 of the center machine 2 performs the transmission processing shown in FIGS. 5, 7, 10, 12, and 13 with the terminal 1.

The process shown in FIG. 5 is a process for verifying information. First, the program block number to be verified is activated to start transmission, and the program block number to be verified is sent to terminal device 1. The process waits for information to be received from terminal device 1. do. In this state, when the program block information of the designated block number is received from the terminal 1, the information is read out and compared with the block information of the same block number saved in the terminal program block information area 242. If the contents of both block information do not match, the block information read from the terminal program block information area 242 and the processing program in the program object area 241 corresponding to this block information are transmitted to the terminal 1.

The process shown in FIG. 7 is a process for forcing the terminal device 1 to change the program. In this case, transmission is started and the block data of the processing program to be changed and the corresponding data are sent to the terminal device 1. Send block information.

Figure 10 shows the process when transmitting a modified program when terminal device 1 is activated. At this time, when the block number of the modified program is received from terminal device 1, the block data of the processing program corresponding to that block number and its corresponding data are sent. Block information is read from the program object area 241 and the program block information area 242 and transmitted to the terminal 1.

FIG. 12 shows the processing when checking the program data when the terminal device 1 is started. At this time, when each block information of the program block information table 15 is received from the terminal device 1, the received block information is transferred to the terminal device. It is compared with each block information saved in the program block information area 242. If there is different block information, a program change flag F corresponding to the area where the block information is saved is set. When such block information collation is completed for all block information, the program change flag F is then searched to check whether any flag F is set. If no flag is set, normal response data is transmitted to the terminal 1. Also, if there is a flag set, abnormality response data is transmitted to the terminal Ill.

After transmitting this abnormal response data, it waits for a reception request from the terminal device 1. Then, when there is a reception request, the block information corresponding to the set program change flag F and the processing program in the program object area 241 corresponding to the block information are transmitted to the terminal device 1.

When there is a reception response from the terminal 1, the program change flag F is reset. This process is repeated until all the program change flags F in the program block information area 242 are reset, and when all the change flags F are reset, end information is sent to the terminal 1 and the process ends.

FIG. 13 shows the process of loading a processing program from the terminal device 1 and saving it in the file 24. For example, when a program data batch designation reception request is sent to the terminal device 1, each of the program data in the program RAM 13 sent from the terminal device 1 is The processing program for each block and each block information of the program block information table 15 are sequentially received and saved in the respective areas 241 and 242 of the file 24. This process ends when the end information data is received from the terminal 1.

Also, when a data request is made to the terminal device 1 by specifying a program block number, the terminal device 1 will send the processing program and block information of the corresponding block number, and each area of the file 24 will receive the processing program and block information. 2
4. ．． 24 Save in the appropriate area in □.

The CPU II of the terminal device 1 performs the transmission processing shown in FIGS. 6, 8, 9, 11, and 14 with the center machine 2.

The process shown in FIG. 6 is a process for collating information by starting the center. First, when a program block number to be collated is received from the center machine 2, the block information corresponding to that block number is transferred to the program block-specific information. It is read from the table 15 and transmitted to the center machine 2. After that, when block information and the corresponding processing program are received from the center machine 2, the program block information table 15 is
and rewrites the corresponding area of the program RAM 13.

The process shown in FIG. 8 shows the forced program change process due to center activation, and in this case
When the processing program to be changed and the block information corresponding to it are received, the program R is changed according to the data.
The corresponding areas of AM13 and program block information table 15 are rewritten.

Figure 9 shows the process of forced program change by starting the terminal.
First, the block number of the program to be changed is sent to the center machine 2. When a corresponding processing program and corresponding block information are received from the center machine 2, the data is stored in the program RAM 13 and the program block information table 15.
Rewrite the corresponding area.

FIG. 11 shows a process when program data is collated upon startup of the terminal, in which each block information of the program block information table 15 is sequentially transmitted to the center machine 2. When the transmission of all block information is completed, it waits for a response from the center machine 2. If there is a normal response from the center machine 2 in this state, this process ends. Further, if there is an abnormal response from the center machine 2, a request to receive the changed program is sent to the center machine 2. In this state, when block information corresponding to the processing program to be changed is received from the center machine 2, the corresponding areas of the program RAM 13 and the program block information table 15 are rewritten with the data.

When this process is completed, a request to receive the changed program is sent to the center machine 2 +1j times, and the same process is repeated. When termination information is received from the center machine 2, this process is terminated.

FIG. 14 shows a process for saving the program data of the terminal 1 in the file 24 of the center machine 2 by starting the center, and when there is a bulk request from the center machine 2, the processing program and the program for every 6 blocks of the program RAM 13 are saved. All block information in the block-by-block information table 15 is transmitted to the center machine 2. When all the data have been transmitted, end information data is transmitted to the center machine 2 and the process ends. Further, when there is a data request from the center machine 2 by specifying a block number, the processing program and block information corresponding to the block number are read from the program RAM 13 and the program block information table 15 and transmitted to the center machine 2.

Note that in the processes shown in FIGS. 5 to 14, the terminal 1
5th in data transfer between and center machine 2.
Figure and Figure 6, Figure 7 and Figure 8, Figure 9 and Figure 10, Figure 1
1 corresponds to FIG. 12, and FIG. 13 corresponds to FIG. 14, respectively.

In this embodiment with such a configuration, when the center machine 2 sends a program block number to the terminal 1, the terminal 1 responds to the corresponding block 'h'j.
The information is read from the program block information table 15 and transmitted to the center machine 2. The center machine 2 compares the received block information with the block information in the program block information area 242 of the file 24.

If they match, it is determined that no change is necessary and the process ends. If they do not match, it is determined that changes are required.
Then, the block information read from the program block information area 242 and the corresponding blocked processing program in the program object area 241 are transmitted to the terminal device 1. Accordingly, the terminal 1 uses the program block information table 1 based on the block information and processing program received from the center machine 2.
5 and the corresponding area of the program RAM 13.

In this way, the processing program and block information of the terminal device 1 can be changed at the blower 291 by activation from the center machine 2. Since data can be changed in block units in this way, the data loading time between the terminal device 1 and the center machine 2 can be completed in a relatively short time. Therefore, when the terminal device 1 performs other tasks, the waiting time is small and no trouble occurs.

Further, when the center machine 2 transmits block information and the corresponding processing program to the terminal device 1, the terminal device 1 stores the program block information table 15 and the program RAM based on the block information and the processing program.
Rewrite the corresponding area of 13.

In this way, the processing program of the terminal device I can be forcibly rewritten by starting the center.

Therefore, if the program to be changed in the center machine 2 is known in advance, the program can be easily changed. In this case as well, since changes are made in block units, data loading time is short.

Also, when you specify the block number of the program you want to change from the terminal 1 and send it to the center machine 2, the center machine 2 reads out the block information for the program block 11 from the program block information area 242 based on the received block number, and Object area 24. The corresponding processing program is read from. This data is then transmitted to the terminal device 1. Thereby, the terminal device 1 rewrites the program block information table 15 and the corresponding area of the program RAM 13 based on the received block information and processing program.

In this way, the processing program of the terminal 1 can be forcibly rewritten by activating the terminal.

Therefore, in terminal 1! If you know the program to be changed in advance, you can easily change that program. Also in this case, since the change is made in the first block Il, the data loading time is short.

Further, when all the block information in the program block information table 15 is transmitted from the terminal device 1 to the center machine 2, the center machine 2 compares each received block information with each block information in the program block information area 242.

If there is block information that does not match, the corresponding program change flag F in the program block information area 242 is set. Then, when all block information collation is completed, the set program change flag F is cleared, and if there is, the block information corresponding to the flag F and the program object area 24 corresponding to the block information. The processing program is sent to the terminal device 1.

As a result, the terminal device 1 uses the program block information table 1 based on the received block information and processing program.
5 and the corresponding area of the program RAM 13 is rewritten.

In this way, by starting the terminal, all the block information of the terminal 1 can be sent to the center machine 2, and it can be checked whether there is a processing program to be changed, and if there is, the processing program can be changed in units of blocks. can. Therefore, even when it is not known whether there is a program to be changed in the terminal device 1, the program can be easily changed.

In this case as well, since changes are made in block units, data loading time is short.

Furthermore, when the center machine 2 issues a bulk transmission request to the terminal device 1 due to center activation, the terminal device 1 transmits all processing programs in the program RAM 13 and all block information in the program block information table 15 to the center machine 2. As a result, center machine 2
Then, all the received processing programs and block information are stored in the 8 area 24. of the file 24. ．． Save to 242.

In this way, the processing program and block information of the terminal device 1 can be saved in the file 24 all at once by starting the center. Therefore, for example, when a processing program is set on the terminal 1, the set processing program can be easily saved in the center machine 2.

Furthermore, when the center machine 2 requests data by specifying a program block number, the terminal 1 sends only the processing program and block information of the corresponding block to the center machine 2.
Then, only the received processing program and block information are saved in the corresponding area of the file 24.

In this way, the processing program on the center machine 2 can be saved in blocks.

In addition, in the above embodiment, the terminal device 1 is connected to the center machine 2.
Although we have described the case where one terminal is connected as an example, it is not necessarily limited to this, and several terminals may be connected to the center machine in one summer, and even in this case. Data exchange between the center machine and the terminals is basically the same as in the embodiment described above.

[Effects of the Invention] As detailed above, according to the present invention, the program data stored in the RAM of the terminal device is divided into a large number of blocks, and each program block data can be changed by activation from the center machine. This can be done block by block while checking against the data of the center machine.
It is possible to provide an information processing device that can reduce the time required to load and save programs by one order of magnitude.

Further, according to the present invention, it is possible to provide an information processing apparatus in which each program block data of a terminal can be forcibly changed by a center machine.
