Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resource automatic allocation device, and more particularly to a system in which an operator performs a resource allocation operation for an external device such as a peripheral device when introducing the device into the system. The present invention relates to a resource automatic allocation device for additionally introducing an external device that automatically allocates resources without depending on an operator.

[0002]

2. Description of the Related Art Allocation of resources such as input / output port addresses and memory addresses used by external devices such as peripheral devices
Conventionally, it was performed by an operator.

That is, when the apparatus A is to be additionally installed in the system, the operator should consider the resource allocation so that the resource allocation will not be duplicated or collided with all the other installed apparatuses. The result is created as a set information file and stored in each device, and the device A refers to this file and uses each resource to operate.

The data stored in the set information file is made up of a required resource name of the device A and an assigned part name of the resource assigned to the device A as a pair.
A file name is set for each device type, and the data storage position is created so as to be constant for each device type, that is, for each file name (for example, the storage position of the allocated part name of resource 1 is for the same type device). Is always the same address).

In computer systems in which resource allocation can be set by software, it has become possible to automatically perform resource allocation without the operator performing resource allocation operations.

In this conventional resource automatic allocation device, a resource allocation availability information table for storing the allocation part name of each resource and the allocation availability information is prepared. At the time of resource allocation, this resource allocation availability information table is referred to. Then, it searches for an allocatable allocation part name of the required resource of the device, allocates it to the device, stores the allocation result in the above-mentioned set information file, and further allocates the resource corresponding to the allocated allocation part name. Rewrite the assignability information in the information table to assignable information,
The resource allocation for the newly installed device is prevented from duplication or collision.

[0007]

In the above-mentioned conventional automatic resource allocation device, at the time of resource allocation, the resource allocation availability information table is referred to search for an allocatable allocation part name of the required resource of the device, and this is assigned. It was assigned to the device.

However, when an external device B that automatically allocates resources is to be additionally introduced to a system that initially uses the external device A that has been resource-allocated by an operator, the following problem occurs. Occurs.

That is, in the conventional automatic resource allocation device, the set information cannot be obtained from the set information file of the external device A allocated by the operator, and therefore the resource considering the set information of the external device A is added. There is a problem in that the allocation permission / inhibition information table cannot be created, and there is a risk of duplication of resource allocation, collision, and the like.

In order to avoid this, the resource allocation of the external device B is preceded, and then the resource allocation to the external device A is performed again with reference to the resource allocation availability information table. There was a problem in that the control program for the above had to be modified.

An object of the present invention is to acquire resource allocation information of an existing device and to allocate the resource when introducing a device for automatic resource allocation into a system having an existing device to which resources have been allocated by an operator. An object of the present invention is to provide an automatic resource allocation device that can automatically set a resource allocation conflict without creating a modification of a control program or the like in an existing device by creating a permission / prohibition information table.

[0012]

A resource automatic allocation device of a first invention is to set a resource information storage position of a set information file for storing set resource information of an existing device to which a resource is allocated by an operator. A stored resource information storage position table, a set information acquisition unit for acquiring the set resource information of the set information file while referring to the resource information storage position table, and acquired by the set information acquisition unit Information table that stores the set resource information that has been set, a resource allocation availability information table that stores the allocation availability information of the resource allocation part of the system, and the resource allocation availability information table with reference to the configured information table And an allocation means for allocating resources to the newly added device by referring to the resource allocation availability information table. It is configured Te.

The resource automatic allocation apparatus of the second invention is
In the automatic resource allocating apparatus of the first invention, the allocating means displays an error when all the necessary resource allocating portions of the newly added apparatus have been allocated.

Register the available allocation part of. Then, every time a device using this resource is installed, the data of the allocated portion of the used resource is updated. FIG. 2C shows a resource allocation permission / inhibition information table 3 in which the allocation prohibition information 31 and 32 updated by the set resources 41 and 42 of the setting information table 4 shown in FIG. 2D is stored. .

FIG. 3 is a flow chart showing an example of the operation of the set information acquisition section 5, FIG. 4 is a flow chart showing an example of the operation of the allocatable information updating section 6, and FIG. It is a flowchart which shows an example.

The operation of this embodiment will be described with reference to FIGS.

For convenience of explanation, in the system in which this automatic resource allocation device is introduced, the set information file 1-
It is assumed that n devices having 1 to 1-n are already installed with resources allocated by the operator, and a new device having the set information file 1-k is introduced into such a system. A case where automatic allocation is performed will be described.

First, the set resource information is acquired from the existing device by the set information acquiring unit 5,
This operation will be described with reference to FIG.

The set information acquisition unit 5 refers to the first information in the resource information storage location table 2 (S11), and sets the same file in the set information files 1-1 to 1-n of the existing device. It searches one after another for the existence of a name (loop of S12, S13, S14).

Set information file 1-having the same file name
When there is 1 (Y branch of S12), the information storage position of the resource 1 in the resource information storage position table 2 is checked (S1).
5), configured resource 1 in configured information file 1-1
The assigned part name of is read (S16), and the information is stored in the set information table 4 (S17).

Further, the information storage position of the next resource is checked (S18), and the following resource information is exhausted (Y of S19).
Branch), and the assigned part name of the set resource is read and stored in the set information table 4 (S16, S17, S18, S1).
9 loops).

The above operation is performed by the resource information storage position table 2
Until there is no more information in the table (Y branch of S14), all set allocation information of existing devices is acquired and stored in the set information table 4. In FIG. 2D, FIG.
A data storage diagram in which the set resources 41 and 42 acquired from the set information file 1-1 shown in (a) are stored in the set information table 4 is shown.

Next, the operation of updating the resource allocation availability information table 3 is performed with reference to the set information table 4, and this operation is performed by the allocation availability information updating unit 6. This will be described with reference to FIG.

Initially, all resource allocation information is stored for each resource in the resource allocation availability information table 3.

The assignability information updating unit 6 first refers to the first information from the set information table 4 (S21), and assignability is not possible to assign to the resource corresponding to this in the resource assignability information table 3. (S22). Hereinafter, until there is no information in the set information table 4 (Y in S24)
Branch), the operation of updating the resource allocation availability information table 3 for that information is continued (loop of S23, S24, S22).

FIG. 2C shows a resource allocation permission / inhibition information table 3 in which the allocation prohibition information 31 and 32 updated by the set resources 41 and 42 of the setting information table 4 shown in FIG. 2D is stored. It is shown.

As a result of the above operation, the resource allocation availability information table 3 stores the information indicating that the resource allocation is not possible for all the resource allocation parts of the existing apparatus to which the resources have been allocated by the operator. If resource allocation is newly performed by referring to the updated resource allocation availability information table 3, duplication of resource allocation, collision, etc. will not occur.

Next, the operation of the allocating unit 7 for allocating resources for a newly introduced device will be described with reference to FIG. 5 by referring to the updated resource allocation availability information table 3.

First, the set information file 1- of the new device
File names that are the same as k (already set information file, since it is a new device, resource allocation has not been performed yet, and allocation name has not been entered) are searched one after another from the resource information storage location table 2 (S31). And (S32, S33, S
Loop consisting of 34)).

When the same file name is found (S32
(Y branch of S36), a resource name necessary for the new device in the resource name of the file is searched (loop of S36, S42, S43), and when the necessary resource name can be searched (Y branch of S36), the resource Search for allocatable part name (S38, S39, S4
(0 loop), if it cannot be searched for, that is, if allocation is not possible (Y branch of S40), an error is displayed (S44).

When the allocatable part name of the resource can be found (Y branch of S38), the allocatable part is allocated to the new device (allocation part as a pair with the corresponding resource name of the set information file 1-k). (The name is stored), and the newly allocated portion of the resource allocation availability information table 3 is updated to be non-allocable (S41), and automatic resource allocation to the device newly introduced next is dealt with.

As described above, the automatic resource allocation device of this embodiment is designed to be used when an automatic resource allocation device is installed in a system having an existing device to which resources have been allocated by an operator. By acquiring the resource allocation information and creating the resource allocation permission / inhibition information table, resource allocation can be significantly facilitated without changing the existing device.
