Description

DETAILED DESCRIPTION OF THE INVENTION (al) Technical Field of the Invention The present invention relates to an 8118@ history display device that displays the name and history of a device used in, for example, an electronic computer system.

Background of the Technology Computer systems are composed of a wide variety of devices, and it is essential to maintain and manage these devices and to save the history of each device so as not to disrupt the operation of the system. be.

tel Conventional Technology and Problems However, conventional equipment history management is generally done using a nameplate affixed to the front of the device's cylinder or a registration ledger, and as a result, many of the devices that make up the system are This has the disadvantage that handling is complicated and cumbersome, that is, the history display configuration using nameplates requires investigation of the installation location of each device, which is inconvenient.

tCU Purpose of the Invention The object of the present invention is to provide a device history display device that can read the history of the device and perform centralized management from the conventional situation as described below, as well as display it, allowing highly efficient management. It is something to do.

tel Structure of the InventionLvI Stated in detail, the present invention provides a display circuit component with a read-only memory element that stores a device name and a device history, and a display device that reads and displays the contents of the read-only memory element. This read data also enables centralized management of device history.

Embodiment of the Invention Fig. 1 (2) and (to) are a partially sectional perspective view and a block diagram of essential parts showing an embodiment of an equipment history display device according to the present invention, and Fig. 2 is a 4: @ 1 is a schematic block diagram illustrating a device history centralized management system to which the technology is applied; FIG.

In these figures, l is a device history display device, 2 is a printed wiring board, 8 is a read-only memory, 4 is a display, 5 is a switch, 6 and 7-1 or ? -n indicates a register, 8 indicates a processing unit, and 9 indicates an input/output device of the computer.

The device history display device 1 has a built-in printed wiring board 2, and the printed wiring board 2 is provided with a socket 2-1. A lead-only socket 8 is inserted into this socket 2-1.

Therefore, the read-only system 8 is a removable QJ function, and inside it contains the device name and device history, specifically the device specifications and manufacturing date.

The serial number and device function version are memorized. The display device 4 is composed of, for example, a segment type or dot matrix type light emitting diode group or a liquid crystal plasma panel. The switch 5 has the function of setting the address of the read-only memory 8 and the function of operating the display 4. The operation of the history display device l of such equipment will be explained below.

When the switch 5 is operated to create an address for the read-only memory 8 and the address is input to the read-only memory 8, the read-only memory 8 outputs the stored content, ie, information corresponding to the stored address, to the register 6. Register 6 is therefore a register for reading read-only memory 8. Although the following explanation has been made assuming that the switch 5 is used, it is needless to say that the address is input from the processing device 18 and that the switch 5 is the same. The contents of the register 6 are output to the processing unit 8 when necessary for centralized management, and are also used as a register. -1 to 7-n. Registers 7-1 to 7-n are registers for the display 4, and each register is responsible for one character. Character groups corresponding to the information stored in the registers 7-1 to 7-n are displayed by pressing the display lighting switch 5-1 of the switch 5! 114 to appear there.

Therefore, by specifying the address, the contents of the read-only memory, ie, the name and history of the device, can be displayed or read.

A case where the present invention is applied to a computer system to centrally manage device history will be described with reference to FIG. Processing device 8
A plurality of input/output devices 9 are connected, and each input/output device 9
Each device is provided with a device history display device 1, and this display device if always displays the name of the input/output device 9 according to the address setting as described above. Of course, in this case, each of the can input/output devices 9 has a different history, and it goes without saying that each of the can input/output devices 9 has a corresponding read-only memory built therein. Now, in managing the device history of each input/output device group, the processing device 8 sets an address when necessary, reads the contents of each read-only memory, and displays or prints out the contents using centralized management.

Effects of the Invention According to the invention described above, the name and history of the device can be displayed on a part of the device housing, and the device name and history can be displayed by simply changing the address instruction for the read-only storage element that stores the device name and device history. Since the history can be centrally managed, it has the effect of making it convenient and efficient to maintain the equipment.
