Abstract

PURPOSE:To prevent the expansion and magnification of a trouble, by storing the difference between the normal disconnection of power source and the automatic disconnection of the power source caused by occurrence of a abnormal condition. CONSTITUTION:When a power disconnection request is made from a system 30, whose power supply is to be controlled, through a data bus 41 after completing its work, a control section 14 writes that the power disconnection is a normal one made in response to the request from the system 30 in an operation storage 12 through another data bus 42. The control section 14 also monitors the abnormality of the system 30 through various detectors for detesting abnormal conditions in the circumstance of the system 30 and the data bus 41 and, when judges that a detected abnormal condition is a trouble enough to disconnect the power once, writes that the power cut is one caused by occurrence of a trouble in the operation storage 12 through the data bus 42. When a preset time is reached, a power supply reserving timer 13 makes a power supply request to the control section 14 through a signal line 44, but, when a power disconnection due to trouble is stored in the operation storage 12, the above-mentioned power supply request is inhibited.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an automatic driving control device and relates to automatic power-on in 1%. (Prior art) Conventional automatic operation control devices automatically turn off the computer when the computer system completes its work, an environmental abnormality involving the computer system occurs, or there is a failure that requires the computer system or system to be powered off. It has an automatic power-off mechanism for turning off the power to the system, and an automatic power-on mechanism for automatically starting up the computer system by turning on the power to the computer system when a preset power-on time is reached. There is.

However, this conventional automatic power-on mechanism unconditionally powers on the computer system when a preset time has been reached. Therefore, for example, even if the previous power cut was an abnormal power cut due to a water leak being detected, the power will be turned on automatically once the scheduled time is reached, and there is a risk that the problem of the computer system will further escalate. There are drawbacks.

(Objective of the Invention) The purpose of the present invention is to memorize the distinction between normal power off and automatic power off due to the occurrence of an abnormality, and if automatic power off due to the occurrence of an abnormality is stored, the failure is removed. An object of the present invention is to provide an automatic operation control device that prevents the spread of a failure by preventing automatic power-on without being turned on.

(Structure of the Invention) The device of the present invention monitors the environmental conditions and the status of the power supplied device, and detects when at least one of an abnormality in the environmental condition requiring disconnection of the power supply or a failure of the power supplied device occurs. a monitoring means that sometimes generates a first signal and generates a second signal in response to a power supply disconnection request in a normal situation from the power supplied device; and supplying the first signal or the second signal. power cutoff signal generating means for generating a power cutoff signal in response to the supply of the first signal; one value of the binary information is written in response to the supply of the second signal; an information storage means into which the other value of the binary information is written, and a third storage means for storing an automatic power-on time for the power supplied device, and when the automatic power-on time is reached;
time signal generating means for generating a signal, and generating an automatic power-on signal in response to supply of the third signal only when the information stored in the information storage means is the other value of the binary information. and automatic power-on signal generating means.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing a system including one embodiment of the present invention. The first system is the automatic driving control device 10
, a power on/off mechanism 20 , and a power controlled system 3
0, a data bus 41 for reporting the operating state or instructing the operating state between the automatic driving control device 10 and the power-controlled system 30, A signal line 45 for instructing the cutting mechanism 20 to turn on or turn off the power, and a signal line 45 that connects the power on/off mechanism 20 to the power controlled system 300.
It is composed of a signal line 46 for controlling the power supply of each device.

Further, the automatic driving control device 10, which is an embodiment of the present invention shown in FIG. A data bus 42 that connects the pre-loading operation memory 1, a power-on reservation timer 13 that notifies the setting of the power-on time and that the set time has been reached, and a power-on reservation timer 13 that informs that the reserved time has been reached. A signal line 44 for notifying the control unit 14 of this, a manual power-on instruction switch 11 for giving a manual power-on instruction, and a signal line 44 for notifying the control unit 14 that the manual power-on instruction switch 11 has been pressed. and a signal line 43 for.

FIG. 2 is a flowchart showing a part of the operation of the control unit 14, which shows the operation when a power-on instruction is received from the signal line 43 or the signal line 44. Please refer to the following for a step-by-step explanation.

First, the operations from the time when the power-controlled system 30 is in operation until the power is turned off will be explained.

If the power supply controlled system 30 issues a request to cut off the power due to the completion of the task via the data bus 41, the control unit 14 sends the power to the operating memory 12 via the data bus 42.
, it is written that the power is turned off outside of normal conditions due to a request from the power controlled system 30.

In addition, the control unit 14 monitors abnormalities in the power supply control system 30 via various detectors (not shown in FIG. 1) and the data bus 41 for detecting environmental abnormalities, and detects abnormalities in the power supply control system 30. When it is determined that the abnormality is a fault that requires power-off, a message is written in the operation memory 12 via the data bus 42 that the power is to be cut off due to the occurrence of the fault. - In any of the above cases, the control unit 14 then connects the signal line 45
The power on/off mechanism 2o is instructed to turn off the power via the signal line 46 under the control of the power on/off mechanism 20.
The power to each device of the power-controlled system 30 is turned off via the power supply control system 30, and the next power-on instruction is awaited.

Next, the operation from the power-off state to the power-on will be explained.

As described above, when the power-controlled system 3° is in a power-off state, the automatic operation control device 1° waits for a power-on instruction.

The method for issuing a power-on instruction is to use the manual power-on instruction switch 11.
There are two methods: one using the power-on reservation timer 13, and the other using the power-on reservation timer 13. In order to perform automatic power-on, the power-on time is set in advance in the power-on reservation timer 13. When the power-on reservation timer 13 reaches a preset time, it issues a power-on request to the control unit 14 via the signal line 44. If the power-on request is from the power-on reservation timer 13 (YF3 branch of step 101), and if the operation memory 12 stores that the power was cut off due to the occurrence of a failure, (YF3 branch of step 102),
There is a possibility that the fault has not been removed.If the power is turned on without removing the fault note, there is a risk that the fault will further spread to the power-controlled system 30.In order to prevent the fault from spreading, turn on the power. The power-on request from the power-on reservation timer 13 is suppressed and the power-on operation is ended. On the other hand, if the power-on request is from the manual power-on instruction switch 11 (N
(O branch, YF3 branch of step 103), if the operation memory 12 does not remember that automatic power off due to the occurrence of a fault has occurred, or even if it is remembered, the power is turned on after the troubleshooting has been completed. Since it can be determined that it is a request, the fact that the power has been turned on is written in the operation memory 12 (step 104), and the power-on request is permitted, and the signal line 45
The power on/off mechanism 20 is instructed to turn on the power via the power on/off mechanism 20 (step 105). The power on/off mechanism 2° powers on the individual devices of the power controlled system 3o via the signal line 46.

Further, even if the power-on request is from the power-on reservation timer 13 (YF3 in step 101), the control unit 14
branch), if the operation memory 12 stores that the power was turned off normally (NO branch of step 102), then the fact that the power was turned on is written in the operation memory 12 (step 1).
04) Permit the power-on request and instruct the power-on/off mechanism 20 to turn on the power via the signal line 45 (step +05).

In this way, in this embodiment, it is possible to avoid automatic power-on when a failure is not recovered, and to prevent the failure from spreading.

(Effects of the Invention) As explained above, the present invention has the advantage that when automatic power is cut off due to the occurrence of a failure, the automatic power supply membrane 9- prevents people from causing a major failure. It has the effect of preventing
