Abstract

PURPOSE:To prevent an electric breakdown due to the erroneous insertion of a package by separating the power source of a mounted package from the power source of a diagnostic device, and checking whether or not each package is correctly mounted when the power source is not supplied to the mounted package. CONSTITUTION:A comparing circuit 10 compares package signal to be inputted to input terminals 6a1 to 6c4 with the package signals read from a ROM 9, and when packages 1a to 1c are mounted on erroneous positions on a common substrate, an inconsistency notifying signal to indicate inconsistency is outputted through a signal line 11b to an output terminal 6g. Consequently the erroneously mounted conditions of the packages 1a to 1c are notified to an operator. Thus the inserting condition of the packages 1a to 1c can be checked before the power source of the respective packages 1a to 1c is applied, and the electric breakdown due to the erroneous insertion can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to diagnostic processing for information processing devices, and particularly to an information processing device that prevents incorrect insertion of a package.

[Conventional technology]

Conventionally, in this type of information processing device, the position at which it is inserted into a common board (bag board) has been determined depending on the type of package, and the input/output direction of signals on the common board has been determined depending on the package to be inserted. In addition, the system has a device for diagnosing device failures, including errors such as incorrect insertion, and after the power is turned on, this diagnostic device diagnoses each device in each processing unit to check that there are no abnormalities.

[Problem to be solved by the invention]

All of the conventional information processing devices mentioned above supply power to the package and then perform failure diagnosis for each processing unit.
If the i part of a package is incorrectly inserted, there will be an output conflict between the packages or with the main body of the wire device, and the disadvantage is that the package alone may cause electrical damage to the main body of the device. .

[Means to solve the problem]

The information processing device according to the present invention includes: means for supplying a diagnostic voltage to each package; a means for receiving the diagnostic voltage and outputting a different signal depending on the type of package;
a storage means that stores a package signal indicating the type of package mounted at each mounting position; a comparison means that compares a signal output from each package using a diagnostic voltage with a package signal read from the storage means; and a power supply device controlled by a coincidence signal output from the means.

[Effect]

The invention enables checking the inserted state of each package before turning on the power of each package, and can prevent electrical breakdown when inserted incorrectly.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of an information processing apparatus according to the present invention. In the same figure, 1a.

1b and 1c have output terminals 28 to 2d and an input terminal 3, as shown in FIG.
c is connected to the package, package signals are output from output terminals 21 to 2d, and the package is mounted on a common board (not shown), 5a to 5c and 5d are signal lines and power supply lines, and 6 is an input terminal. 6.1~6a4 + 6bl
~6b4 + 6el~6c4 and 6d, output terminal 6
This is a diagnostic circuit which checks whether each of the packages 1a to 1c is mounted at a predetermined position on a common board (not shown), as shown in FIG.

In the diagnostic device 6 shown in FIG. 3, 7 is a voltage V power supply line, 8 is an address generator that outputs an address signal indicating the mounting address position of each package 1a to 1c, and 9 is an address generator for each package 1a to 1c. Since the mounting position is determined in advance, a ROM in which a package signal indicating the type of package to be mounted at this mounting position is stored in advance;
compares the package signals inputted from the input terminals 611 to 6.4 with the package signals read from the ROM 9, and when they match, outputs a power supply instruction signal from the output terminal 6f via the signal line 11&; Time signal line 11b
12a to 12d are resistors connected between input terminals 6.1 to 6e4 and ground.

Note that the power supplies for the packages 1a to 1c and the power supply for the diagnostic device 6 are separated, and only the diagnostic device 6 is supplied with power by turning on an external power switch (not shown). Then, the power supply instruction signal outputted from the output terminal 6f of the diagnostic device 6 turns on the power to the packages 1&-1c, and each package 18-1c enters the power supply state.

Next, the operation of the information processing apparatus with the above configuration will be explained. First, when an external power switch (not shown) is turned on, power supply voltage is supplied only to the diagnostic device 6, and the diagnostic device 6 enters the operating state. For this reason, packages 1a to 1c
The power supply voltage level of the diagnostic device 6 is supplied via the power line T, the output terminal 6e, the power line 5d, and the input terminal 3. Therefore, package signals are output from the output terminals 28-2d of packages 1&-1c. This package signal is input to the comparison circuit 10 via the signal lines 5a to 5c and the input terminals 611 to 6c4 of the diagnostic device 6.

Meanwhile, the address generator 8 of the diagnostic device 6 operates and generates an address signal indicating the mounting position of each package 11 to 1c.
OM9. Output to. Therefore, the ROM 9 reads out the package signal stored in advance by inputting this address signal and outputs it to the comparison circuit 10. Therefore, the comparison circuit 10 compares the package signal inputted to the input terminals 611 to 6.44C with the package signal read from the ROM 9, and when the packages 1a to 1c are correctly mounted on the common board, a matching signal is obtained. A certain power supply instruction signal is outputted from the output terminal 6f via the signal line 11m.

Therefore, the packages 16 to 1c are brought into a power supply state by this power supply instruction signal. On the other hand, package 1a~
When the package 1c is mounted at the wrong position on the common board, a mismatch notification signal indicating mismatch is outputted to the output terminal 6g via the signal line 11b, and the operator is informed that the package 1
It is possible to notify that the mounting positions of 8 to 1c are incorrect.

〔Effect of the invention〕

According to the information processing device according to the present invention, the power source of the package to be mounted and the power source of the diagnostic device are separated, and a means for checking whether each package is correctly mounted in a state where power is not supplied to the mounted package. By providing a hole, it is possible to check whether a package is inserted incorrectly, and it is also effective in preventing electrical damage due to output conflict between packages or between a package and a device if a package is incorrectly inserted. .
