Abstract

PURPOSE:To efficiently attain a specified processing in spite of the number of total peripheral equipments by temporarily transferring identification information of the specified peripheral equipment from a controller-side to the peripheral equipment, adding identification information at the time of transferring information from the peripheral equipment to the controller-side so as to return information. CONSTITUTION:A controller 1 is connected with the peripheral equipments 2 through an interface 3. The controller 1 transmits control information having an information field to which a value showing that it is the specified equipment is set to the specified peripheral equipment executing the specified processing. The specified peripheral equipment edits notice information including the information field and transmits it to the controller 1-side. Since the value that it is the specified equipment is set in the information field of the controller 1 at the time of receiving notice information, it can judge whether the specified processing is to be executed or not. Thus, a processing for referring to whether it is the specified peripheral equipment executing the specified processing or not is executed in the peripheral equipment 2 and a load by the specified processing of the controller 1 is reduced.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a hardware/software interface control method for interfacing a control device and its peripheral devices, and in particular to management of identification information related to peripheral devices in a balancing device. Regarding the method.

[Conventional technology]

Conventionally, when there are multiple peripheral devices and a control device performs specific processing on a specific peripheral device, the control device has information indicating whether or not it is the specific device, and notification information from any peripheral device is stored in the control device. When performing this identifying process only on a specific device at the time of reception, the control device collates information indicating whether or not the specific device is the applicable specific device, and determines whether or not to perform the identifying process.

Note that this type of technology is known from pages 192 to 196 of "Principles and Structure of Electronic Computers" (10th edition, published by the Institute of Electrical Engineers of Japan on February 20, 1987).

[Problem to be solved by the invention]

In the above conventional technology, when there are many peripheral devices and specific processing is to be performed on a small number of specific peripheral devices, when notification information is received, a verification process is performed to determine whether or not specific processing is to be performed on all of the numerous peripheral devices. There is a problem in that the processing time associated with the specific processing in the control device becomes long, resulting in a decrease in the performance of the control device.

An object of the present invention is to solve the problems of the conventional method and efficiently perform identification processing regardless of the number of all peripheral devices.

[Means to solve the problem]

In order to achieve the above purpose, the identification information of a specific peripheral device that should be stored on the control device side is temporarily transferred to the peripheral device side,
When information is transferred from this peripheral device to the control device side, identification information is added and sent back.

[Effect]

From the control device to a specific peripheral device that performs specific processing,
Send control information that has an information field set with a value indicating that it is a specific device. Thereby, when the notification information is subsequently received from the specific peripheral device, a value indicating that it is a specific device is set in the information field, and it is possible to determine whether or not to perform specific processing based on this.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a diagram showing the connection state between the control device 1 and the peripheral devices 2. The control device 1 and each peripheral device 2 are connected to each other via the interface 3.
connected through. The format of the control information and notification information transferred between the control device 1 and the peripheral device 2 through this interface 3 is configured as shown in FIG. That is, the control information format 31 includes an information field 312 in addition to a control information type 311 and various parameters.
have.

In addition, the notification information format 32 is the notification information type 32.
1 and various parameters, it also has an information field 322.

FIG. 3 shows the internal configuration of each peripheral device 2. As shown in FIG. This peripheral device 2 supplies the control information input to the control information receiving section 21 to the peripheral device control section 26 and also to the information field extracting section 22. Only the information field 312 is extracted. The extracted information is then stored in the information field storage section 23.

On the other hand, when the peripheral device control unit 26 needs to transmit notification information to the control unit, the information in the portion of the notification information format 32 excluding the information field 322 is supplied to the notification information editing unit 24. The notification information editing unit 24 that receives this outputs the information field accumulated from the information field storage unit 23 and edits the notification information in the notification information format 32 including this information field. Then, the edited notification information is sent to the control device 1 by the notification information transmitter 25.
Let the side send it.

Next, to explain the control device 1, the configuration for transmitting control information in the control device 1 is shown in FIG.
In the figure, 111 indicates a maintenance command input section. When information specifying a specific peripheral device is input to the maintenance command input section 111, this information is passed to the control information editing section 112, where the control information is converted into the control information format 31. is edited and the information field in the control information is set to a value indicating the specific peripheral device. The edited control information is
Together with the specific device designation information taken over from the maintenance command input section 111, it is output to the control information transmitting section 113, and the control information transmitting section 113 causes the control information transmitting section 113 to transmit it to the peripheral device 2 designated as the specific peripheral device through the interface 3.

After receiving the control information in this way, the configuration for receiving the notification information transmitted from the peripheral device 2 is shown in FIG. Receive at. At this time, the information field in the notification information is set with a value for determining whether the peripheral device 2 that sent the notification information is a specific device.

The received notification information is input to the specific processing execution unit 122, regardless of whether it is a specific peripheral device, and then passed to the notification information processing unit 123, which is common to the specific peripheral device and other peripheral devices. processing is executed. The specific processing execution unit 122 performs processing according to the specific processing execution unit flowchart shown in FIG. 6, and executes specific processing only on notification information from the specific device.

Although this embodiment shows a case in which one type of specific processing is targeted, it is possible to target multiple types of specific processing by expanding the information field and the storage section of the peripheral device. Furthermore, by changing the software section of the control section without changing the information field and peripheral devices, it is possible to add the above-mentioned specific processing function.

In addition, in this embodiment, the specific peripheral device is determined by a maintenance personnel command, but when the control device detects a sign of a peripheral device abnormality, or the peripheral device that has become abnormal is determined by the control device. It is also possible to have the control device automatically determine the specific peripheral device by using the time when the device recovers through control as a trigger.

〔Effect of the invention〕

As described above, according to the present invention, since the peripheral device side has information as to whether or not it is a specific peripheral device that performs specific processing, this data verification processing is performed by the peripheral device, and the control device The load caused by specific processing can be reduced. Further, since the peripheral device is not aware of the content of the specific process or that it is a specific device, it can be implemented with a simple mechanism, and there is no need to change the peripheral device when another specific process is added.
