Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to data transfer between a portable terminal (hereinafter referred to as a POT) and a host information processing device (hereinafter referred to as a host), and in particular to a host. This relates to a data transfer processing method when performing all data entry from POT.

(Prior Art) An example of the connection between a host and a POT according to the prior art is shown in FIG. In Figure 2, 400 is the host, 500 is P
It is OT. In the host 400, 41 is a control unit;
2 represents a data processing section, and 43 and 44 each represent a transmission control section. In the POT 500, 51 is a control unit, 52
is a transmission control section, 53 is a program section, 54 is a data section,
55 is an input/output control section, and 56 and 57 are input/output sections, respectively.

In conventional data entry systems of this type, POT
Program section 53 and data section 54 in 500
There is a limit to the storage capacity of , and it is necessary to enter business data that exceeds this limit.

In such a case, if the host 400 does not have a function to transfer programs and data to the POT 500, the programs and data required for each job are fixed and used for each POT. Furthermore, when connecting POTis with different transmission control procedures at the same time, the host 400 performs different transmission control for each POT.

(Problems to be Solved by Issue E!A) The conventional program and data transfer method described above may require programs and data that exceed the capacity i1' of the program and data sections of the POT. In such a case, it is necessary to separately use necessary programs and data for each POT, so there is a drawback that the tasks that can be used for each POT are limited.

In addition, in data transfer between POT and host, POT
Transmission control for each OT is executed by the host, so when data is transferred to the host from multiple POTs with different transmission control procedures, the processing load of transmission control increases on the host, which reduces the host's processing efficiency. There is a drawback that it does.

An object of the present invention is to provide a POT with a data transfer function,
Programs and data required by the OT 1Send from the host to the POT in response to requests from the POT,
When transferring data between the POT and the host, a data communication processing device (hereinafter referred to as DOP) is interposed between the two.
Data is transferred between the host and the DOP using one transmission control procedure, and data is transferred between the DOP and the host using multiple identical or different transmission control procedures. POT2g
The object of the present invention is to provide a more structured program that can be easily connected to a host, and a data transfer method.

(Means for Solving the Problems) The program and data transfer system according to the present invention is configured to include one or more POTs, a host, and a DOP.

Each of the one or more POTs has a data transfer means,
It is possible to receive a program and data, execute the program and use the data, and process and transfer input data.

The host is capable of transmitting programs and data required by the POT in response to requests from the POT.

A DOP is placed between a host and one or more POTs, and uses one transmission control procedure with the host and the same or different transmission control procedures with one or more POTs. This is for controlling transfer.

(Embodiment) Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the program and data transfer system according to the present invention. 1st
In the figure, 100 is the host, 200idDOP,
300 is POT. Host 1o.

In the figure, 1 is a control section, 2 is a program section, 3 is a data section, 4 is an interface control section, and 5 is a transmission control section.

D OP 2001C ol, nte, 1o are transmission control parts,
11 is a relay control section, and 12 and 13 are transmission control sections, respectively. In the POT 300, 30 is a transmission control section, 31 is a control section, 32 is a program section, 33 is a data section, 34 is an input/output control section, and 35 and 36 are input/output sections, respectively.

In FIG. 1, business start instruction information inputted by the operator through the input/output section 35, 36'tl- of the POT 300 is transmitted by the transmission control section 30'? of the POT 300. ! : Transferred to the DCP 200 via. The DOP 200 "?" relays the instruction information and transfers it to the host 100.

The host 100 receives instruction information from the POT 300,
POT 300 necessary for the work to be performed
The program and data are selected from the program section 2 and data section 3 of the host 100 and transferred to the DOP 200 via the transmission control section 5.

The DOP 200 relays the above programs and data and transfers them to the POT 300. POT 300 and 1'
i. The program and data transferred from the host 100 via the DOP 200i are loaded into the entire program section 32 and data section 33, and then the transferred program is activated. Thereafter, the POT 300 can execute the specified task using the transferred program and data.

Note that once a program has been loaded into the POT 300 according to the above procedure, and the operator gives an instruction to start a task that can be executed using this program, the program and data will not be transferred: POT
300 is in control by itself.

Data input from the υP OT 300 by the operator is routed to the data section 33 of the POT 300 and transferred to the D OP 200 via the transmission control section 309.

The DOP 200 converts the transferred data via the relay control unit 11t according to a transmission control procedure suitable for the host 100, and transfers it to the host 100.

The host) 100 stores input data from the POT 300 into the data section 3 and executes data processing.

DOPzoorU is capable of transmitting multiple po'raoo'2 systems, and the transmission control unit 12゜1 of DOP200
3 each have an identification address, and each POT 300
is identified.

By adding this address to the data transferred between all the hosts 100, the data between the host 100 and the POT 300 can be processed separately for each POT3oolC.

The relay control unit 11 between the transmission control unit 10 and the transmission control units 12 and 13 performs all mutual conversion of transmission control procedures.

(Effects of the Invention) As explained above, the present invention provides the POT with a data transfer function, and transmits programs and data required by the POT from the host to the POT in response to requests from the 2PO'r. , in data transfer between POT and host, DOPt is interposed between them, and data is transferred between the host and DOP using one transmission control procedure,
By transferring data between the OP and the host using multiple identical or different transmission control procedures, even if the POT attempts to perform various tasks that exceed the physical storage capacity of programs and data,
Since the host can receive the programs and data necessary for the relevant work and execute all the processing, this has the effect of significantly increasing the efficiency of POT use.

In addition, even when changing programs and data in POT, it can be done by simply changing the programs and data held in the host, so especially in systems that use a large number of POTs, it is not necessary to input programs and data in POT. This has the effect of greatly reducing the amount of work required to replace it.

Furthermore, by intervening between the DOPt-POT and the host to relay data transmission, it is possible to reduce the processing burden related to transmission control on the host side.
When operating during OT 1rFiJ, problems can be overcome by simply improving the functionality of the DOP by changing the number of POTs in operation or adding new models, and this has the effect of reducing the workload when changing the system.
