Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a status display device for displaying the operation status of each component in a computer system. 2. Description of the Related Art In some cases, a computer system for performing information processing includes an upper main computer and a lower control computer for controlling various driving mechanisms. In such a system, it is necessary to always grasp the operating state of each computer and the operating state of each drive mechanism. An information processing system including a magnetic tape library system will be described as an example of a computer system. In FIG. 2, reference numeral 10 denotes an information processing system, which comprises a main computer (M / CPU) 1 for performing information processing and a magnetic tape library system 2 having a magnetic tape built in a cartridge 3. The library system 2 includes, as main components, an accommodation shelf 4 in which a number of unit shelves 41 accommodating the cartridges 3 are arranged, a robot mechanism 5 for handling the cartridges 3, a magnetic tape driver 6, and a control unit 7. Handles a large number of cartridges 1 efficiently,
In addition, in order to cope with the malfunction of the robot mechanism 5, the storage shelf 4 is divided into two areas 4A and 4B as shown in the figure.
Two sets of robot mechanisms 5A and 5B are provided corresponding to each area. If one set of storage shelves 4 cannot accommodate the cartridges 3, a plurality of sets are arranged in series or in parallel, and a plurality of drivers 6 are provided. Next, each of the robot mechanisms 5A and 5B includes a bar code reader 511 and a chuck mechanism 51 as actuators as shown in the attached detailed drawing.
2 and X, Y, Z shown in FIG.
The drive mechanism 52 moves in the direction and rotates (R) about the Z axis to correspond to the unit shelf 41. The control unit 7 includes a control computer (C / MPU) 71, a control circuit (CONT) 72, a memory (MEM) 73, a keyboard (KB) 74, a flexible disk (FD) 75, and the like.
75 stores a program and the like for (C · MPU) 71. A bar code for identifying the magnetic tape is written on the side surface of each cartridge 3, and the coordinate data and bar code of each unit shelf 41 containing the bar code are stored in advance in the ME.
Recorded in M73. When a magnetic tape is used, a bar code of a required magnetic tape is designated from the main computer 1 to the control computer 71. The control computer 71 reads the coordinate data of the unit shelf 41 with respect to the bar code from the MEM 73, drives the driving mechanism 52 by the control circuit 72 in accordance with the read data, moves the hand 51 to the position of the corresponding unit shelf 41, and stops. Barcode reader 511
To read and confirm the bar code of the cartridge 3. Next, the hand 51 is rotated by 180 °, and the chuck mechanism 512 is rotated.
, The cartridge 3 is chucked and moved to the position of one of the drivers 5, and the cartridge 3 is mounted on the cartridge 3 to access data. When the use of the magnetic tape is completed, the cartridge 3 is stored in the original unit shelf 41 in a reverse procedure to the above. In the above, when one of the robot mechanisms, for example, 5A malfunctions and can be retracted, it is retracted to an appropriate place, and the other 5B handles the cartridge 1 to both areas 4A and 4B. , Among the plurality of drivers 6,
If there is a malfunction, the operation of the library system 2 is controlled so as not to be interrupted, for example, its use is stopped. In the information processing system 10 described above, it is necessary to always grasp the operating state of each unit as described above. The information to be grasped includes (a) information indicating the normal / abnormal operation states of the main computer 1 and the control computer 71, and (b) each robot mechanism 5
Information indicating the normal / abnormal operation of each of the X, Y, Z movements and R rotation of A and 5B, (c) information indicating the normal / abnormal operation of each driver 6, and (d) other information. Function of each bar code reader 511 and chuck mechanism 512
There is actuator information indicating an abnormality. above
The information in (a) is basically necessary to grasp the operating state of each computer. If any of the robot mechanisms 5A or 5B is found to be abnormal based on the information in (b), as long as the information in (a) is normal, the malfunctioning robot mechanism is evacuated and the library system 2 Operation is continued. Also, unless all the drivers 6 are abnormal,
Since the library system 2 can be operated, the information of (c) is necessary. Therefore, (a) to (c) are essential information for the operation of the system 10. On the other hand, the read function of each bar code reader 511 and the chuck function of each chuck mechanism 512 are grasped from the actuator information of (d), and the retracted abnormal robot mechanism is inspected and repaired based on this information. That is, (d) is the security information. In addition to these, there are various kinds of information indicating the progressing state of the handling that changes every moment, but these are appropriately changed as necessary, and are not necessarily needed immediately together with the above-mentioned maintenance information. [0004] In a computer system, usually, each computer is provided with a display for displaying its operating state. However, in the information processing system 10 described above, not only the information of (a) for each of the computers 1 and 71, but also a display for each of the information of (b) to (e) for each of the robot mechanisms 5A and 5B is required. However, when these are used as separate display devices, there is a disadvantage that the cost is high. Therefore, it is advisable to provide one status display device and display all of the above information by program processing of the microprocessor. However, troubles may occur due to program mistakes or errors during loading, etc.In such cases, it is necessary to display at least the above essential information (a), (b), (c) Thus, the operation of the library system 2 can be avoided by evacuating the malfunctioning robot mechanism. Although the above has described the specific information processing system 10 having the library system 2, in general,
The situation is the same in a system including a higher-level main computer and a lower-level control computer that controls a drive mechanism. By the way, this kind of computer
