JPH05182032A - Detection of errorneous mounting of card - Google Patents

Abstract

PURPOSE:To speedily and securely detect the errorneous mounting of a card. CONSTITUTION:Identification numbers C-1 to C-n showing the type of the cards 2-1 to 2-d and slot numbers S-1 to S-n showing slots J-1 to J-n on which the cards 2-1 to 2-n are mounted are made into pairs and they are stored in RAM 11. Card number storage parts 20-1 to 20-n storing the identification numbers C-1 to C-n are provided for the cards 2-1 to 2-n. The slot numbers S-1 to S-n are designated from a control part 12 to RAM 11 and the output instruction of the corresponding identification numbers C-1 to C-n is given. Furthermore, the slot numbers S-1 to S-n are designated to a slot recognition part 3 from the control part 12 so as to give the output instruction of the identification numbers C-1 to C-N of the cards 2-1 to 2-n which are actually mounted on the corresponding slots J-1 to N-n. A comparison part 13 compares the identification numbers C-1 to C-n transmitted from RAM 11 with the identification numbers C-1 to C-n transmitted from the cards 2-1 to 2-n which are actually mounted on the designated slots J-1 to J-n. When both do not coincide, the effect is displayed in a panel part 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card erroneous mounting detection for detecting erroneous mounting of a card in an information processing device or the like in which a plurality of types of cards are mounted at prescribed mounting positions according to the system configuration. It is about the method.

[0002]

2. Description of the Related Art Conventionally, on a backboard on which each card is mounted, there is a pin indicating a location for each mounting position of each card. And read which mounting position each card was inserted into.

[0003]

However, in this method, since the diagnostic device recognizes the mounting position of the card by the pin on the backboard, if the card is erroneously inserted at a mounting position other than the specified one, the diagnostic There is a problem that the device recognizes a wrong mounting position and it takes time to detect it.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and uses a pair of an identification number indicating the type of a card and a slot number indicating the position where the card is to be mounted. A storage means for storing and an identification number storage means for storing the identification number of the card on the card are provided, a slot number is designated, an identification number corresponding to the slot number is read from the storage means, and a slot number is designated. The identification number of the card actually mounted at the mounting position corresponding to the slot number is read from the identification number storage means of the card, and if the read identification numbers do not match, that fact is displayed. It is a thing.

[0005]

According to the present invention, therefore, when the identification number of the card actually mounted at the mounting position and the identification number of the card to be mounted at the mounting position do not match, that fact is displayed as erroneous mounting. It

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The card erroneous mounting detection method according to the present invention will be described in detail below.

FIG. 1 is a block diagram showing a main part of an information processing apparatus to which this card erroneous mounting detection method is applied.

In the figure, 1 is a memory section, and 2-1 and 2-2.
-N is each mounting position (hereinafter referred to as slot) J1 to Jn
Various cards actually mounted on the card, 3-1 to 3-n are slot recognition sections for recognizing the slots J1 to Jn, 4 is a panel section for displaying a detection result, 5 is a bus, and 6 is a control line.

The memory unit 1 comprises a backup RAM 11, a control unit 12 and a comparison unit 13. Backup RA
M11 is a card number storage unit 11-1 that stores identification numbers C1 to Cn indicating the types of the cards 2-1 to 2-n, and a slot J1 in which the card is mounted as a pair with the identification numbers C1 to Cn. To slot numbers S1 to S indicating Jn
The slot number storage unit 11-2 stores n.

Each of the cards 2-1 to 2-n stores a card number storage section 20-1 to which the identification numbers C1 to Cn of the card are stored.
20-n.

The slot recognizing units 3-1 to 3-n are slot number storing units 30-1 to 30-n for storing the slot numbers S1 to Sn indicating the slots J1 to Jn, and the control unit 12.
The slot number comparison units 31-1 to 31 for comparing the slot number designated via the control line 6 with the slot numbers stored in the slot number storage units 30-1 to 30-n.
-N.

Next, the operation will be described. In the memory unit 1, the control unit 12 designates the slot number S1 to the backup RAM 11 and outputs an output command of an identification number corresponding to the slot number. In response to this, the backup RAM 11 sends the identification number C1 to the comparison unit 13 as the identification number corresponding to the slot number S1.

Further, the control unit 12 specifies the slot number S1 to the slot recognition units 3-1 to 3-n via the control line 6 and a card actually mounted in the slot corresponding to the slot number. Issue the output command of the identification number. In response to this, the slot comparison unit 3 in the slot recognition unit 3-1
1-1 is the designated slot number S1 from the control unit 12,
The storage slot number S1 of the slot number storage unit 30-1 is compared with each other, it is confirmed that they are the same, and the output command of the identification number from the control unit 12 is sent to the card number storage unit 20-1 in the card 2-1. send.

The card number storage unit 20-1 includes a control unit 12
In response to the output instruction of the identification number from, the stored identification number C1 is output and sent to the comparison unit 13 via the bus 6.

The comparison unit 13 has the identification number sent from the backup RAM 11 and the card number storage unit 20-1.
Compare with the identification number sent from.

In this case, the identification number C1 sent from the backup RAM 11 and the identification number C1 sent from the card number storage unit 20-1 match, but if they do not match, the card 2 defined in the slot J1 is used. -1 is not inserted, that is, it is determined that the card is erroneously inserted, and a display to that effect is displayed on the panel unit 4 to notify the operator.

With respect to the cards mounted in the slots J2 to Jn, erroneous insertion is detected in the same manner as described above.

[0018]

As is apparent from the above description, according to the present invention, the slot number is designated and the identification number corresponding to the slot number is read out from the storage means, and the slot number is designated to the slot number. The identification number of the card actually mounted at the corresponding mounting position is read from the identification number storage means of the card, and if the read identification numbers do not match, a message to that effect is displayed. You will be able to discover the implementation quickly and reliably.
