JPS603052A - Hierarchical electronic computer system - Google Patents

Abstract

PURPOSE:To reduce installation space on the whole and also to attain cost reduction by allowing a high-order and a low-order electronic computer system to back up their data files mutually. CONSTITUTION:Respective data gathered from respective data gathering terminals 70 are processed to construct a data file 50, and the processed data are transmitted to the high-order computer system through a transmitting adapter. If one data file 50 is shut down in said state, the data gathered from the data gathering terminal 70 is transmitted to the high-order computer system as it is. At this time, the high-order electronic computer system stores the data in the data files 20 and 60 respectively. Then, the data is transferred to the low-order electronic computer system reversely when the data file 50 in the shutdown state is made reusable.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plurality of systems that process data in two layers.

Conventionally, in a 4-machine system that takes advantage of this, the data files in each layer are duplicated (in systems that require data immediacy, the system itself is made dual).
It is common to do 37f+, and the method will be explained with reference to FIG. In FIG. 1, the upper computer system consists of a central processing unit 1 having a transmission adapter between the CPU and the lower computer system, and dual data files 2 and 3.

In addition, each lower-level computer system has t''1-CPU.
Each central processing unit 4 has a transmission adapter with the upper 17 child computer systems and each data collection terminal, and each cheetah file 5 with dual configuration.
.

Even if a file on the other side goes down, a total of nine electronic machines in each hierarchy can continue data processing by disconnecting the file using software.

The ratio is shown in Figure 1! The processing flow of the system is shown in Figure 2. That is, in normal operation of one electronic monitoring device in each hierarchy, writing to each cheater file is performed simultaneously on the main and slave files, and reading is performed with the main file as the primary file. When the main file is destroyed, both the thread and the slave file are logged at the same time by logging the abnormality information (from this file, printer device, etc.) and automatically switching to the slave file. The data collection process will continue to operate without stopping unless something goes down.

The conventional hierarchical system is structured as described above, and each layer has two files for each computer system (2.3 files in Figure 1). 5,6)
This method has two drawbacks: it requires a large amount of space for installation and is expensive.

The non-invention was also proposed by looking at the above q", f = I'i VLb, and the purpose and 1" is to wear a lower finger hat -
The data file of the machine system is kept on one machine, and even when the lower electronic 13" machine system is expanded due to system expansion, the data file is saved on one machine at a time, and the installation space is saved. [・] In order to reduce the size and cost, it is located in (12) Sui 84 type city, which provides the complete cannon system.

Hierarchical IC chipping machine system (TRJ) by uninvented system, first electronic computer section 7 data processing (hierarchical IC chipping machine) '7. )=,, In the P system, the central processing unit and the dual-value cheetah file are connected to the upper-level 5-child metering system, and the upper-level electronic meter η, the transmission adapter with the rear system, and each Each central processing unit 1'1- with a data collection and transmission attacher and each one Cheetah file and each sub-processor with 1t
When the l'jN-Roku system and the Cheetah file of the lower-level electronic computer Sysdeno are down, the upper-level computer B'l
The JR (i:z system) is equipped with a means for collecting data from the lower electronic meter system, and is designed to save space and reduce costs. It is.

An embodiment of the invention will be described in detail below with reference to the drawings.

FIG. 3 is a system configuration diagram of an embodiment of the invention, and in FIG.
Look, it is the same vessel as shown in Figure 1, 1.2.3, 4.5.7. It is something. In FIG. 3, the data file 6 shown in FIG. 1 has been deleted. This method takes advantage of the fact that modern small computers have larger memory capacities, making it possible for online programs to reside in memory.

The operation of the above-mentioned embodiment of the unexploded BJ-1 will be discussed.

FIG. 4 1711: This is a diagram showing the bank up processing flow of the embodiment of the present invention shown in FIG. 3. In FIG. 4, each data collected from each data collection terminal 70 is processed via a transmission adapter, a Cheetah file 5θ is constructed, and this data is sent to the Juichi Sushi and Zizan Hatsushi systems via the Loe Data All Transmission Adapter. In this state, when the Cheetah file 50 goes down, the data collected from the data collection terminal 70 is directly transmitted to the upper electronic system. In the host computer system, 4% of all this data is stored in data files 2θ and 3θ.

When the downed data file 5θ becomes usable again through the work of maintenance personnel, this data and the minimum processed data necessary for data restoration on the lower-level computer system? - The lower electronic meter η is transmitted backward from the L-level weight 1 child meter n device system.

The machine system will be produced later in normal operation. Therefore, according to the invention, -j''L is the data file 5 of the lower-level computer system.
The data collection process can continue unless both θ and online go down.

In the above-mentioned embodiment, a transmission adapter is used to connect the upper electronic excavator system and the lower electronic computer system, but PLO (process input
A 7' access interface such as tQutpuj 1 may also be used.

As described above, according to the present invention, in a hierarchical system in which data processing is performed in a hierarchical manner, the cheat files of the upper and lower electronic management systems can be mutually backed up. Since it has been designed to be able to do so, it has the excellent effect of making the general space travel a little easier and reducing costs at the same time.
