Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spare package storage device for storing (stock) a plurality of spare packages.

[0002]

2. Description of the Related Art Generally, a communication or computer system device is constructed by mounting a plurality of packages on a rack (here, a package means a printed circuit board on which electronic components such as ICs are mounted. ). Recently, based on an instruction from a remote maintenance center or the like, a robot is guided under the control of a maintenance control device to replace or expand a plurality of types of packages of a device to be maintained (hereinafter referred to as a device to be maintained). In many cases, maintenance work is performed. In such a case, the robot takes out a spare package (spare package) stored in the spare package storage device from the spare package storage device and mounts it on the maintenance target device. The maintenance control device that controls this maintenance work stores the type information of the packages stored in the spare package storage device by itself, and stores the spare packages stored in the device itself according to instructions from the maintenance center. Find out, give the information to the robot, and perform maintenance work. Conventionally, various types of robots for performing maintenance work have been developed, but a spare package storage device for storing a spare package only has a structure for storing each package.

[0003]

In the maintenance work using the conventional spare package storage device, the normality of the spare package taken out from the spare package storage device is determined by mounting the spare package on the maintenance target device and then executing the maintenance target device. There is no choice but to confirm using the self-diagnosis function of. Therefore, if a certain spare package fails during storage and the spare package is mounted on the maintenance target device, the maintenance control device, maintenance center, etc. recognize the fault for the first time by the self-diagnosis function of the maintenance target device, and again You will have to find a spare package and replace it. For this reason, there is a drawback that the loss time of the maintenance work increases and the invalid operation time of the robot also increases.

An object of the present invention is to provide a spare package storage device capable of reducing the loss time and the invalid operation time of the robot due to the replacement work of the spare package even if the spare package fails during storage. To provide.

[0005]

A spare package storage device of the present invention is a spare package storage device for storing a plurality of packages, and storage detection for detecting whether or not the package is stored in the spare package storage device. Means, a type means for detecting the type of the stored package, a diagnostic means for diagnosing the stored package,
The storage means stores a detection result of the storage detection means, a detection result of the classification means, and a diagnosis result of the diagnosis means, and a communication means that outputs the storage content of the storage means in response to an instruction.

In this case, it is provided with a time measuring means for measuring a time and an instruction means for instructing the communication means to periodically output the contents stored in the storage means according to the time measured by the time measuring means. However, it may be provided with an instruction means for instructing the communication means to output the stored contents of the storage means when a report instruction is received.

[0007]

That is, the present invention is such that the spare package storage device autonomously outputs the storage state, type, and diagnostic result of the spare package to the maintenance control device, maintenance center, or the like.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a spare package storage device of the present invention, FIG. 2 is a control flow chart of the embodiment of FIG. 1, and FIG. 3 is another control flow chart of the embodiment of FIG. is there. As shown in FIG. 1, the maintenance target device 1 includes a plurality of packages 2a, 2b, ..., 2n, and these packages 2a, 2b ,. The spare package storage device 3 stores a plurality of spare packages 4a, 4b, ..., 4n, and includes a control unit 5, a diagnostic monitoring circuit 6, a memory 7, and a communication circuit 8. The control unit 5 is the package 4
The detection control of the stored states of a, 4b, ..., 4n is performed. The diagnostic monitoring circuit 6 detects whether or not the packages 4a, 4b, ..., 4n are stored at the respective storage positions, detects the types of the packages 4a, 4b, ..., 4n, and detects the packages 4a, 4b ,.・ Perform 4n diagnosis. That is, the diagnostic monitoring circuit 6 also serves as a storage detecting unit, a classifying unit, and a diagnostic unit. The memory 7 is a storage means for storing the detection and diagnosis results of the diagnosis monitoring circuit 6. The communication circuit 8 guides the robot 10 and communicates with a maintenance control device 9 that controls maintenance work. The robot 10 is guided by the maintenance control device 9 to perform work such as replacement of each package and expansion. Further, the spare package storage device 3 of the present embodiment is provided with a timer (not shown) as a time measuring means for measuring time and periodically giving an instruction to the control section 5.

Next, the control method of this embodiment will be described. As shown in FIG. 2, the control unit 5 periodically checks whether or not the packages 4a, 4b, ..., 4n are stored by the diagnostic monitoring circuit 6, and if they are stored, checks their types. , Make a diagnosis and check the normality. Then, the contents stored in the memory 7 are updated according to the above result. The maintenance control device 9 attaches the package type information and instructs the spare package storage device 3 to report the storage position. The control unit 5, which has received this instruction via the communication circuit 8, searches the memory 7 for normal packages 4a of the designated type,
4b, ..., 4n (normal package) are stored in the storage position and returned to the maintenance control device 9 as a stock status notification via the communication circuit 8. Maintenance control device 9
Causes the robot 10 to perform a maintenance operation by attaching the received storage position information in the spare package storage device 3 and the maintenance target package mounting position information in the maintenance target device 1 to the robot 10.

Instead of periodically checking the spare package storage device 3, the storage state may be checked when the maintenance control device 9 gives a report instruction. Further, as shown in FIG. 3, instead of replying when the report instruction is received from the maintenance control device 9 as described above, the maintenance control device 9 is periodically notified of the storage state and the maintenance control device 9 The state may be held, the storage position of the normal package of the designated type in the spare package storage device 3 may be found when the work is required, and the work may be instructed to the robot 10.

[0012]

As described above, according to the present invention, the storage state, type, and diagnosis result of the spare package are output, so that the maintenance control device, the maintenance center, and the like can overlook the failure of the stored spare package. Since the faulty spare package is not replaced or added as a target for expansion, there is an effect that work loss time and robot invalid operation time can be reduced.
