FIG. 1 is a diagram showing physical hardware for causing the computer system 1 to operate.

In the example of Fig. 1, the computer device 100 is connected to devices such as the motor 4, the motor 5, and the heater 6.

The computer device 100 is composed of, for example, an MPU (Micro Processing Unit) 2 and a memory 3.

An output device such as a secondary memory device of a hard disk device, an input device such as a mouse or a keyboard, or a display device may be connected to the computer device 100.

Fig. 2 is a view showing an example of the configuration of the computer system 1 of the first embodiment.

In the second drawing, the application 7 (hereinafter also referred to as the application 7) is a software for realizing the function provided by the computer system 1, and the operation start (ON) request and the operation stop of the output device of the device management unit 8 are requested ( OFF) Requirements.

The action start (ON) request is an instruction to request the start of the device action (action start request).

The operation stop (OFF) request is an instruction to stop the operation of the device.

The power management unit 9 is included in the device management unit 8 and determines whether to actually output an operation ON instruction or an operation OFF instruction of the device based on an operation start request (ON) request or an operation stop (OFF) request transmitted by the application program 7. Device driver 14.

The operation request receiving unit 10 is included in the power source management unit 9, and receives an operation start (ON) request or an operation stop (OFF) request transmitted by the application program 7.

The operation request receiving unit 10 selects a device (a device that is required to start an operation) that is required to be activated by the operation or a device that is recorded in an operation suspension table to be described later as a selection device.

The operation request receiving unit 10 corresponds to an example of a device selection unit.

The operation permission determination unit 11 is included in the power source management unit 9, and refers to the rule table 13 to determine whether or not the selection device selected by the operation request receiving unit 10 is allowed to operate.

The action suspension table 12 is a table for registering a device (suspended device) that is not permitted to be activated by the action permission determination unit 11.

Rule Table 13 is a table describing the rules for determining whether or not to allow the device to operate.

The device management unit 8, the power source management unit 9, the operation request receiving unit 10, and the operation permission determining unit 11 are loaded into the memory 3 shown in Fig. 1 and executed by the micro processing unit 2.

Further, the power source management unit 9 does not need to be included in the device management unit 8, and the device management unit 8 and the power source management unit 9 are configured to be able to call each other.

Further, the operation suspension table 12 and the rule table 13 are stored in the memory 3 shown in Fig. 1.

The memory 3 is equivalent to an example of suspending the device memory unit.

The device driver 14 is a software that operates the device 15.

The device 15 is an input/output device such as a motor or a heater.

Next, an example of the rule table 13 is shown in FIG.

In the rule table 13, a rule for starting the action of the post-permission action device is defined in accordance with the combination of the first action device and the rear action device.

The first action device is the device that is active before the action device.

The post-action device is a selection device selected by the action request receiving unit 19.

In the rule table of Figure 3, "License", "Delay", and "Priority" are defined.

"License" means that the rear operating device can be operated even if the first action device is operating.

"Suspend" means that the first action device is in operation, and the rear action device cannot be operated.

The first action device that describes "suspend" is a device that restricts the operation of the rear action device, which is equivalent to the restriction device.

"Priority" means that if the first action device is in operation, the action of the first action device is temporarily stopped, and the action of the rear action device is started.

The first action device in which "priority" is described is a device that stops the operation for the start of the operation of the rear operation device, and corresponds to the stop candidate device.

For example, application 7 requires device A to start when device B or device When the standby C is in operation, the operation of the device A is not started.

On the other hand, when the application 7 requests the operation of the device A to start, if only the device D is operating, the operation of the device A is started.

In addition, when the application 7 requires the operation of the device C to start, if the device D does not operate, and the device A (or the device B) is in operation, the operation of the device A (or the device B) is stopped, and the action of the device C is caused. Start.

Next, a processing example of the computer device 100 of the present embodiment will be described with reference to FIGS. 6 to 8.

First, when the application 7 specifies a device (for example, a motor) to the device management unit 8 and outputs an operation start (ON) request (for example, motor rotation start or heater power ON) (S101), the operation request in the power source management unit 9 is accepted. The unit 10 receives an operation start (ON) request through the device management unit 8.

The operation request receiving unit 10 selects an operation to activate the device specified by the request as a selection device, and inquires whether or not the operation permission determination unit 11 permits the operation of the selection device (S102).

The operation permission determination unit 11 selects one device among the plurality of devices connected to the computer device 100 as the first action device (S103).

Then, the action permission determination unit 11 refers to the rule table 13 and extracts the defined rule for the combination of the selected first action device and the selection device (post-action device) (S104).

When "suspend" is defined in the rule acquired in S104, the operation permission determination unit 11 acquires the operation state of the first action device (S105), and if the first operation device is in operation, the notification operation request reception unit 10 "suspend" (S106).

If the first action device is not operating, the action permission determination unit 11 is for all The first action device performs the same confirmation.

In other words, if the operation permission determination unit 11 has an unconfirmed device (S112), the process from S103 is repeatedly executed.

The operation permission determination unit 11 notifies the operation request receiving unit 10 of the "suspend", and adds the selection device to the operation suspension table 12 (S107).

The action suspension table 12 may be in the form of FIG. 4 or the form of FIG.

Fig. 4 shows an action suspension table 12 in which the device for suspending the operation is managed in the form of a list.

Fig. 5 shows an action suspension table 12 for managing the device in which the operation is suspended in the form of a bit pattern.

When "permission" is defined in the rule acquired in S104, the operation permission determination unit 11 performs the same confirmation for all the first operation devices.

In other words, if the operation permission determination unit 11 has an unconfirmed device (S112), the process from S103 is repeatedly executed.

When the result of "suspend" is not obtained for all the devices, the operation permission determination unit 11 notifies the operation request receiving unit 10 of "permission".

The operation permission determination unit 11 notifies the operation request receiving unit 10 of the "permission", and the transmission device management unit 8 outputs an operation start (ON) instruction for designating the start of the operation of the selection device (S113).

When "priority" is defined in the rule extracted in S104, the operation permission determination unit 11 acquires the operation state of the first action device (S108), and if the first action device is operating (S109), the device management unit 8 instructs the device. The driver 14 stops the operation of the first action device (S110).

Further, the operation permission determination unit 11 performs the first action for stopping the operation. The operation of the device is restarted later, and the first action device that has been stopped is added to the action suspension table (S111). If there is an unconfirmed device (S112), the process from S103 is repeatedly executed.

When the result of "suspend" is not obtained for all of the first-action devices, the operation permission determination unit 11 notifies the operation request receiving unit 10 of "permission".

The operation permission determination unit 11 notifies the operation request receiving unit 10 of the "permission", and the device management unit 8 outputs an operation activation instruction (ON) indicating that the operation of the selection device is started to the device driver 14 (S113).

Then, when the application 7 specifies the device to the device management unit 8 and outputs an operation stop (OFF) request (for example, motor rotation stop or heater energization stop) (S201), the operation request receiving unit 10 transmits the device in the power source management unit 9. The management unit 8 accepts an operation stop (OFF) request.

The operation request receiving unit 10 transmits, via the device management unit 8, an operation stop (OFF) instruction for instructing the operation of the designated device to be stopped to the device driver 14 (S202).

Then, the operation request receiving unit 10 deletes the registration of the device from the operation suspension table 12 when the operation suspension table 12 includes the designated device (S203).

Then, the operation request receiving unit 10 selects one device as the selection device from among the devices registered in the operation suspension table 12 (S204), and inquires of the operation permission determination unit 11 whether or not the selection device is operable (S102).

The processing of S102 to S113 is the same as that of S102 to S113 shown in Fig. 6, and therefore the description thereof will be omitted.

When the operation request accepting unit 10 notifies the "permission" by the operation permission determining unit 11, The registration of the selected device is deleted from the action suspension table 12 (S205).

Further, the operation request receiving unit 10 confirms whether or not the device registration is present in the operation suspension table 12 (S206), and if there is a device registration, the processing after S204 is repeatedly executed.

According to the processes of the seventh embodiment and the eighth embodiment, the operation request receiving unit 10 and the operation permission determining unit 11 can start the operation of the device (suspended device) registered in the operation suspension table 12 in S107 or S111 in Fig. 6 .

As described above, according to the present embodiment, it is possible to control the device to suspend the operation or start the operation based on the rule table for setting the operation of the device for the combination of the devices.

In addition, even if the action of the device is changed, it is only necessary to change the rule table, so that the change can be localized to improve the independence of the application (portability, reusability).

Further, by changing the content described in the rule table during the operation of the device, it is possible to flexibly change a part of the operation of the device.
