Abstract

PURPOSE:To enable a device to operate with an old program even in the case of a failure in downloading by discriminating between an area where the old program and data are stored and an area where a new program and data are stored. CONSTITUTION:When a message for the start of downloading is received from a host device 10 through a line, a main body control part 3 uses a device stored with the old program and data are stored between two external storage devices 1 and 2, e.g. 2 to store a program and data which are downloaded. At this time, if there is a file which fails to be downloaded last time and can not be used, the external storage device 1 and 2 stored with the file is used to store the program and data which are downloaded. This device once receiving one block of data from the host device 10 confirms the correctness of the data with its check code and sends the result to the host device 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to countermeasures against download failure when programs and data in an ATM are replaced by downloading from a host device.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 59-43474, conventional devices only communicate data between the center and the terminal, and do not communicate programs that control the entire terminal or list the bank fulcrum names. Large amounts of data are generally processed locally on each terminal.

[Problem to be solved by the invention]

In the prior art, if a line failure or the like occurs during downloading, the conventional program is destroyed, so the device cannot operate until the new program is correctly loaded.

An object of the present invention is to enable the device to operate with the old program even when downloading fails.

[Means to solve the problem]

In order to achieve the above purpose, in external storage devices that store programs and data,
By separating the area for storing old programs and data from the area for storing new programs and data, it is possible to download new programs and data while preserving the old programs and data.

[Effect]

By separating the area for old programs and data from the area for new programs and data, the old programs and data will not be destroyed when storing the downloaded programs and data, so even if the download fails, the old The device can be started up using programs and data, and the device will not become inoperable.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of an example of an automatic cash handling device to which the present invention is applied.

This device has external storage devices 1 and 2 for storing programs and data, and the programs and data stored here are read into the main body control section 3.

Executed. The main body control unit 3 includes a customer operation unit 5 and a host device 10 that provide guidance to the user and perform key manual operations.
A communication control unit 4 that performs communication with the card, a card handling unit 6 that reads and writes magnetic cards and IC cards, and a bankbook/statement handling unit that reads magnetic stripes on bankbooks, prints transaction details, and issues and prints statement slips. A banknote dispensing unit 7, which deposits and withdraws banknotes, sorts the banknotes internally, and distinguishes between genuine and counterfeit bills, and a banknote dispensing unit 8, which deposits and withdraws coins, internally sorts the coins, and distinguishes between genuine and counterfeit coins. It is connected to the coin/manufacturer section 9, etc., which performs the following operations, and controls them all at once.

The host device 10 has a data file corresponding to each user of this device, and the deposit and withdrawal processing of this device is carried out while communicating with the host device 10 through a line.

FIG. 2 shows the structure of files stored in the external storage device 1.2 provided in this apparatus.

The loader 20 is read into the memory on the main body control section 3 and executed by a simple program reading program built into the main body control section 3.

The loader 20 is also a program for reading a program file on an external storage device, and when it is executed, the operating system (abbreviated as O8) 21 that performs the basic output of this device, The business programs 22 that control transaction processing and the like are sequentially read and executed.

The data 23 includes data for determining the changeable specifications of this device, data for screen display, audio data for guidance, and the like.

Further, the reserve 24 is a surplus portion, and decreases as the program or data file becomes larger.

Figure 3 shows the exchange of messages between the host device and this device during downloading.

Assuming that a message to start downloading is received from all higher-level devices through the line, the main control unit of this device will
Of the two external storage devices, the one containing old programs and data, for example, the external storage device w2, is used to store downloaded programs and data.

At this time, if there is a file that cannot be used due to a previous download failure, processing is also performed to use the external storage device containing the file for storing the downloaded program or data.

If the data is to be stored in the external storage device 2, first, in response to a download start message, this device checks the operation of the selected external storage device 2 and sends the result to the host device.

When the host device confirms that the external storage device 2 of this device operates normally, it transmits the file name and revision number of the new program or data to be downloaded. This device determines whether the file has already been loaded from the file name and revision number, and if it has not been loaded, sends a download request, and if it has already been loaded, sends a rejection message to the upper layer.

When the host device confirms that the file has not been loaded, it sends the size of the next file to be transferred in blocks. This device checks the storage area of the external storage device and sends to the host device whether the file can be stored.

When the host device confirms that there is an area to store the file, it sequentially transmits the file one block at a time. It is assumed that the host device adds a code to each block to check the validity of the data in that block. When this device receives one block of data, it verifies the validity of the data using the check code and sends the result to the host device.

When the host device confirms that this device has received data normally, it sends the next block of data, and if this device cannot receive data normally, it sends the data of the same block. shall be resent. In addition, in this device, if data is not sent even after 10 times, the process ends due to a transmission error.

When the host device finishes transmitting all blocks, it transmits a download completion message. This device returns a normal end message if all data for the message has been stored normally, and returns an abnormal end message if it has not been stored normally.

It is assumed that the host device remembers whether it is necessary to download again next time based on the reply content to this end message.

At this point, unless a new program or data has already been loaded, if the device terminates abnormally, the new program will not exist in the device, but the old program will remain undestroyed, so the old program will cause the device to Operation is possible.

Even if you download Durham or data, there is a period of time before you can start using it. For example, if you downloaded it on September 1st, the program will not be able to run until September 20th.
If you need to run the old program until then, you should not delete the old program and data immediately after downloading, so you will need to copy it after the new program starts operating. .

Also, if you download according to this example, it is uncertain whether the program that this device has is old or new, so please check the revision number of the program that can be executed when starting up the device.
It is necessary to check the following, but by including this in the message with the host device and checking it when starting up the device, the device can be operated with programs and data that operate correctly.

〔Effect of the invention〕

According to the present invention, since old programs and data are not destroyed during downloading, it is possible to operate the device using old programs and data even if downloading fails.

Also, in this example, the external storage device 2 may be out of order.

Even if it becomes unusable, it is possible to use the spare area 1 of the other external storage device as shown in FIG. 4 to store a new program without destroying the old program or data. Also, if the size of spare area 1 is insufficient, it is possible to overwrite the old program, but in this case, if the download fails, the device will not be able to start up. Only if it becomes impossible to do so.

In addition, in this example, after the download is complete, there will be two types of programs and data: old programs and data and new programs and data, but after confirming that they have been stored correctly, you can create new programs and data on top of the old programs and data. By overwriting the data, you can have two sets of new programs, and even if you become unable to read or write due to a failure of the external storage device you are using, you can always read the spare programs and data, so you can always create new programs. The device can be operated using information and data. However, this method separates the external storage devices that store the new program and data from the old programs and data, so that even if one external storage device fails, the other program and data can be used to continue operating the device. It is possible to make it work.

Furthermore, by having two sets of new programs, even if the program or data in use becomes unreadable, it is possible to always operate the device with the new program or data using the spare program or data.

Furthermore, by receiving and receiving revisions of currently executable programs and data from the host device, it is possible to operate the device with programs and data that always operate correctly.
