Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a terminal processing system in which a control program loaded into a main storage device can be rewritten.

[Conventional technology]

The control program of an information processing device is a program for managing the execution of processing programs, controlling input/output, etc.
Usually, it is stored in a storage device such as a storage element built into each information processing device or a disk device. Then, when the device is started, it is automatically loaded into the main memory. Here, if it becomes necessary to remove defects (debugging) or improve the control program, the contents of the storage device will be rewritten. This requires replacing the memory element and rewriting the contents of the disk and device.

However, in a large-scale system that connects many terminal devices, such as a deposit processing system at a financial institution, it would take a huge amount of time to rewrite the control program for each terminal device. Work is required.

Therefore, without preparing a control program for each terminal device,
A method is adopted in which a control program is prepared for the connection partner that is connected to and controls this system, and the control program is loaded into the main memory of each terminal device through a communication line at the same time as the system is started. ing.

This method is called downline loading, and has the advantage that improvements and changes to the control program can be made easily and freely.

[Problem that the invention seeks to solve]

However, as the business content of the system becomes more complex, its control program also becomes relatively large in size, and it takes a long time to load it.

In this case, there are disadvantages in that the startup of the system is delayed and the load on the connected destination increases.

The present invention has been made with attention to the above points, and an object of the present invention is to provide a terminal processing system that can shorten the time for loading a control program and reduce the burden on the connection partner. It is.

[Means for solving problems]

The terminal processing system of the present invention includes a main storage device, an auxiliary storage device that can store a control program, a control device that executes processing using the control program loaded into the main storage device, and a power source. and an initial setting device that controls the storage process of the control program in the main storage device after the power is turned on. The control program transferred from the other party is loaded into the main storage device and controlled to be stored in the auxiliary storage device at the same time, and after the power is turned off, the control program stored in the auxiliary storage device is saved. When the power is turned on again, either the control program transferred from the connection destination or the control program stored in the auxiliary storage device is transferred to the main storage device in response to a load instruction from the connection destination. The feature is that it is controlled so that it is loaded into.

[Effect]

In this way, by providing an auxiliary storage device on the terminal device side and storing the previously loaded control program, when restarting business using that control program, the control from the connected party There is no need to transfer programs, reducing the burden on the other party. Furthermore, in this case, the time required for loading is significantly reduced compared to transferring the control program through a communication line.

In addition, you can freely rewrite the control program in order to follow the load instructions from the connection destination, whether to use the control program transferred from the connection destination or the control program stored in the auxiliary storage device. It is possible to take advantage of the original functions of this system.

〔Example〕

The figure is a block diagram showing an embodiment of the terminal processing system of the present invention.

In the figure, a terminal device 10 is connected to a connection partner 20 through a communication line 30.

It is assumed that the connection destination 20 is connected to a large number of terminal devices 10 (not shown) via this communication line 30, for example. This connection destination 20 is a host device for controlling these terminal devices 10 or another similar system connected to this system.

The communication line 30 is, for example, a dedicated line for data transmission or a telephone line.

The terminal device 10 includes a main storage device 1, an auxiliary storage device 2,
It is composed of a control device 3, a communication device 4, an input/output device 5, and an initial setting device 6.

The main storage device 1 is a storage device for storing and executing control programs, arithmetic processing programs, and the like.

The auxiliary storage device 2 is a storage device with a capacity sufficient to store the largest size control program that may be used by the terminal device 10, and is comprised of a nonvolatile memory, a magnetic disk device, or the like.

The control device 3 is a device including a microprocessor or the like that executes predetermined processing using a control program or the like stored in the main storage device 1 . The communication device 4 is connected to the communication line 30
This is a device that sends and receives signals through the Input/output device 5
In this case, the input/output request received by this communication device 4 is sent to the control device 3.
This is a device that processes the data after it has been analyzed.

The initial setting device 6 is a circuit that detects when the terminal device is powered on, receives a load instruction from the connection partner 20 via the communication device 4, and controls the loading of the control program.

The terminal processing system of the present invention having the above configuration operates as follows.

First, when the terminal device 10 is powered on (not shown), the initial setting device 6 stores the main storage device 1 and the auxiliary storage device 2.
Check whether the control program is stored in the .

First, a case will be described in which no control program is stored in either the main storage device 1 or the auxiliary storage device 2.

In this case, the initial setting device 6 connects the communication device 4 and the communication line 3.
A control program load request is sent to the connection destination 2o via 0.

In response to this load request, the connection destination 20 transfers the control program to be used by this terminal device 10 to the communication line 30.
Transfer via. The initial setting device 6 receives this control program and loads it into the main storage device 1, while also storing it in the auxiliary storage device 2.

The control device 3 uses the control program loaded into the main storage device 1 to start predetermined processing.

Next, when the use of this terminal device 10 is finished and its power is cut off, the control program stored in the main storage device 1 will be deleted, but the control program stored in the auxiliary storage device 2 will be saved as is. be done.

When the terminal device 1o is started again, the initial setting device 6 checks the main storage device 1 and the auxiliary storage device 2 and recognizes that the control program is stored in the auxiliary storage device 2.

Thereby, the initial setting device 6 performs control to load the control program stored in the auxiliary storage device 2 into the main storage device 1.

After the loading of this control program is completed, the control device 3 starts predetermined processing.

On the other hand, regardless of whether the control program is stored in the auxiliary storage device 2 of the terminal device 10, the connection destination 2
may instruct the loading of its own transferred control program. This occurs when the control program needs to be rewritten.

In this case, the connection partner 20 outputs an instruction to forcibly load the control program, and the initial setting device 6 recognizes this. As a result, the control program transferred from the connection partner 20 is loaded into the main storage device 1, and the control program previously stored in the auxiliary storage device 2 is rewritten with a new control program.

This allows the control program to be changed at any time.

[Modified example]

The terminal processing system of the present invention is not limited to the above embodiments.

Each block shown in the embodiment may be rewritten into various blocks having similar functions, and these blocks may be divided or integrated.

〔Effect of the invention〕

According to the terminal processing system of the present invention described above, the control program can be loaded from the auxiliary storage device to the main storage device when the power is turned on, so even large-sized control programs can be loaded at high speed. The system can be started up quickly (and the load on the connected destination can be reduced).
