Abstract

PURPOSE:To form an internal bus with no limitation given to the number of adaptor parts connected to a processor part and to attain a system with flexibility, by connecting the terminals corresponding to each other in terms of input and output between the adjacent slots and securing connection between the input/output pins corresponding to each other within an adaptor part attached into a slot. CONSTITUTION:The input/output terminals 1 and 2 corresponding to each other between the adjacent slots are connected to each other as shown by a solid line by a wiring 3 set on a backboard. The wirings 4 shown by dotted lines connecting those terminals 1 and 2 are provided into adaptor parts A11, A12 and A21 (packed into slots S2, S3 and S5) respectively. Therefore the parts A11 and A12 are connected to the slots S2 and S3 in a processor P1 packed into the slot S1. While no connection is secured between both terminals 1 and 2 in the processors P1 and P2 and therefore the internal buses of both processors P1 and P2 are separated from each other. An internal bus is connected to the slot S5 from the slot S1 after an adaptor part is packed tentatively into the slot S4 in place of the processor P2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bus connection structure, and particularly to a bus connection structure in which one or more adapter units are connected to one processor unit to a backboard in one host body. The present invention relates to a connection structure of a bus that connects a processor section and an adapter section when a plurality of output control sections are mounted.

[Conventional technology]

Conventionally, this type of bus connection structure connects the processor section and the adapter section using a wiring pattern on the backboard manufactured according to a predetermined implementation form, or by wiring the backboard according to the system configuration. It was composed.

[Problem that the invention seeks to solve]

The conventional bus connection structure described above has the following drawbacks.

In the case of a bus connection structure with a pattern according to a predetermined implementation form: 1. The number of adapter units connected to the processor unit is limited.

2. The system configuration is limited.

3. The wiring pattern for connecting the bus between the slots for installing the processor, processor section, and adapter section provided on the backboard is fixed, so if you try to change the system configuration, empty slots will be created. Even though there are extra slots, it may not be possible to add a control unit.

In the case of a bus connection structure in which bus boards are connected by wiring, 1. Wiring is required for each system, which is time-consuming and costly.

2. When adding an adapter unit, etc., it is necessary to rewire.

3. Mistakes in wiring work may occur in different locations for each system.

[Means for solving problems]

In the bus connection structure of the present invention, each of the output terminals of each of the slots is connected to one of the slots in a backboard in which a plurality of identical slots each having a plurality of input terminals and a plurality of output terminals are provided side by side. One or more adapters are provided with wiring connected to the corresponding ones of the input terminals of the slots lined up on the side, and are attached to the slots lined up continuously on the one side of the slots in which the processor unit is installed. The device is characterized in that wiring is provided inside the unit to connect each of the input terminals to the corresponding one of the output terminals.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of a system to which an embodiment of the present invention is applied, in which a general-purpose bus 10 includes processor units P1 to P,
are connected to the processor section P1, and adapter sections Ail to AI, 1 are connected to the processor section P1 via an internal bus B1. ,,1-A! Ifi is connected. The number of adapter units connected to internal bus B1 varies depending on the system. It goes without saying that each of the internal buses 81-B must be independent.

Figure 2 shows a bus with an internal bus for the system shown in Figure 1.
In Figure 2, which is a diagram showing the wiring of the board,
Slots 81 to S5 indicated by chain lines are connectors provided on the backboard, the processor part P1 is mounted in the slot S1, the adapter part All connected to the processor part P1 is mounted in the pro-soto S2, and the slots S3 has a processor section P! An adapter section A12 connected to the processor section A12 is installed in the slot S4, a processor section P2 is installed in the slot S5, and an adapter section P21 connected to the processor section P2 is installed in the slot S5.

Terminals are arranged in two rows in each of the slots 81 to S5, with the terminal on the left side in FIG. 2 being the input terminal 1, and the terminal on the right side being the output terminal 2.

Wiring 3 provided on the backboard connects the corresponding input/output terminals 1.2 of adjacent slots as shown by solid lines in the figure. Adapter part All, AI□, A2□
(Mounted in slots S2, S3, and S5) are provided with wires 4 (indicated by dotted lines in the figure) that connect mutually corresponding input/output terminals 1.2.

Therefore, the processor Pl mounted in the slot S1 has an adapter part A I installed in the slot S2 and a slot S3.
H, A 12 are connected. Processor section P1. In p2, the input terminals 1.2 are not connected to each other, so the internal buses of each processor section Pl+P2 are separated. If an adapter section is installed in slot S4 instead of processor section P2, then pro-soto S is installed from slot S1.
It will be appreciated that up to 5 internal buses can be connected.

〔Effect of the invention〕

As explained above, the present invention provides an input terminal and an output terminal for one signal in each slot provided in a backboard, and connects corresponding input/output terminals in an input/output relationship between adjacent slots. In addition, by connecting the corresponding input/output bins in the slot with the adapter section installed in the slot, an internal bus can be configured without limiting the number of adapter sections connected to the processor section, making the system flexible. The effect of being able to build a
