Fig. 4 shows the connection relationship of automatic power cut-off control devices in a multi-processing system consisting of two or more processing systems, and the automatic power cut-off control device 8 is the same as the automatic power cut-off control device shown in Fig. 3. , and the automatic power cut-off control device 8 connects each processing system 171 (i=1, 2...t
n) means a power supply control device 18 that is connected through the same data control interface as shown in FIG. 20).

Next, the operation of one embodiment of the present invention will be explained with reference to FIGS. 2 and 3.

Power is sequentially applied to each component of the processing system system 6 from the power supply control device 7, and after the processing system system 6 starts processing information, it performs the information processing task, completes the series of processing normally, and then performs other operations. When there is nothing left to process, the program in the central processing unit 1 issues a command to the automatic power-off control device 8 to instruct the automatic power-off control unit 8 to turn off the power by normal termination of the processing system.

The automatic power-off control device 8 receives a command at the interface section 9, and when the command decoding section 10 decodes the power-off instruction command due to normal termination of the system, the automatic power-off control device 8 displays on the display section 15 the power-off instruction based on the normal termination of the system. , sequentially sends a power-off instruction signal to the power-supply control device 7 via the power-off instruction section 14, and simultaneously turns off the power to each component of the information processing system under the control of the power-supply control device 7. The instruction unit 14 sends a power cutoff signal to the electric light power source, air conditioner power source, etc. in the station building, thereby cutting off the power source in the station building.

Further, the time monitoring unit 11 includes a time monitoring counter.

After the processing system starts operating, the counter is automatically updated, and the counter is reset based on a counter reset command issued from the central processing unit at regular intervals. If the counter reset command is not issued at regular intervals, the counter will overflow and the time monitoring unit 11 will detect a failure in the central processing unit system (7) hardware or software, making it impossible to operate the processing system. Display unit 1 indicates that the system power is cut off due to a failure in the central processing unit system.
5, and sequentially sends a power-off instruction signal to the power supply control device 7 via the power-off instruction section 14, and sequentially turns off the power to each component of the information processing system under the control of the power supply control device 7. At the same time, the power cut-off instructing section 14 turns off the power inside the station building, and the external notification interface section 16 notifies the outside, such as the maintenance personnel's room and security personnel's room, of the abnormality.

In addition, temperature abnormality detectors, humidity abnormality detectors, smoke abnormality detectors, earthquake detectors, water leakage detectors,
When external sensors such as various gas abnormality detectors and external intruder detectors detect an abnormal state, they send an abnormality detection signal to the external abnormal state monitoring section 12, and when the external abnormal state monitoring section 12 receives the external abnormality signal, it detects an abnormal state. Based on the signal, if it is necessary to cut off the power in an emergency such as an earthquake or fire, the cause of the external abnormality is displayed on the display section 15, and an emergency-simultaneous message is sent to the power supply control device 7 via the power cut-off instruction section 14. A power-off instruction signal is sent, and the power to each component of the information processing system is urgently and forcibly cut off under the control of the power supply control device 7. At the same time, the power-off instruction section 14 causes the A power cut instruction signal is sent to each power source to turn off each power source in the station building, and the abnormality is notified to the maintenance staff room, safety staff room, etc. via the external notification interface section 16.

On the other hand, if the cause of the external abnormal state is various gas abnormalities, water leakage abnormalities, external intruder detection, etc., and there is no need to urgently cut off the power, the external abnormal state monitoring unit 12 reports the detected abnormal state to the status reporting unit 13. The status reporting unit 13 creates an abnormal state detection layer for the central processing unit 1 and notifies the central processing unit 1 of the external abnormal state detection via the interface unit 9.

The program in the central processing unit 1 analyzes the cause of the abnormal state, and in the case of an external abnormality that does not require turning off the power, it continues execution of the process, but in the case of an external abnormality that requires turning off the power, it performs the necessary evacuation. After processing and pre-recovery processing, etc., a power-off instruction command is issued to the automatic power-off control device 8 based on external abnormality detection, and the automatic power-off control device 8 receives the command at the interface section 9 and sends it to the command decoding section 10. When the system decodes the power-off instruction command due to external abnormality detection, the display section 15 displays the system power-off due to external abnormality,
Sequentially sends power-off instruction signals to the power supply control device 7,
Using the same method as the system power cutoff method based on normal termination, the power to each component of the information processing system is sequentially cut off, and at the same time, each power supply in the station building is also cut off, and when an external intruder is detected, the external notification interface unit 16 Notify the safety officer's office, security guard's office, etc. via.

Furthermore, in the case of a multiplex information processing system configuration as shown in FIG. 4 consisting of two or more central processing units, an interface unit 9 of the automatic power cut-off control device 8 as shown in FIG.
The instruction decoding unit 10, time monitoring unit 11, and display unit 15 are capable of receiving instructions, decoding instructions, monitoring time for abnormal conditions, and displaying stop conditions for each processing system, and are located at the central location of each processing system. If the processing units synchronize and control the entire information processing system using the same control program, when the system power is turned off due to normal termination, the logical layer of the power-off instruction command issued from each central processing unit automatically turns off the power. This is performed when the control device 8 establishes the condition.

In this case, the automatic power cut-off control device 8 is operated as shown in FIGS.
In the same way as the system power cutoff method based on normal termination explained in connection with the figure, a power cutoff instruction signal is sent to the multiplex information processing system power supply control device 18 and each power supply in the station building, and the entire system is shut off. Turn off the power.

Further, system power is cut off due to a failure in the central processing unit system when no counter reset command is issued from all the central processing unit systems.

In this case, the automatic power cut-off control device 8 instructs the power supply control device 18 for the multiple information processing system and each power source in the station building to cut off the power in the same manner as the method of cutting off the system power based on the failure of the central processing unit system. A signal is sent to turn off the power to the entire system, and the cause of the power cut is displayed on the display section 15.

In a multiplex information processing system, when the central processing units of each processing system are operated by mutually independent control programs, the automatic power cut-off control device 8 is activated when receiving an instruction to turn off the system power due to normal termination or when the central processing unit When it is necessary to turn off the system power due to the detection of a failure in a device system, power is turned off to components related only to the processing system system that issued the power-off instruction command or to the processing system system that detected the failure in the central processing unit system. The instruction is sent to the power supply control device 18 for multiplex information processing system, and the display section 15
The cause of power-off is also displayed for each processing system.

On the other hand, in a multiplex information processing system, the system power cut-off method based on external abnormality detection is applicable to each processing system, even if the central processing units of each processing system control the entire information processing system in synchronization with the same control program. Even when the central processing units of the processing system are operated by mutually independent control programs, when it is necessary to urgently turn off the system power, the automatic power cut-off control device 8 performs the emergency simultaneous power cut-off when an external abnormality is detected. In the same manner as above, an emergency/simultaneous power cut-off instruction signal is sent to the multiplex information processing system power supply control device 18, and a power cut-off instruction signal is sent to each power supply in the station building to turn off the power of the entire system. , the cause of the power disconnection is displayed on the display unit 15, and an external maintenance personnel room is also notified of the abnormality.

As explained above, by using an automatic power cut-off control device in an information processing system, the system operator can operate the information processing system by permanently staying near the information processing system and monitoring the system. Since the operator of the system can recognize the cause of system operation stoppage without having to do so, the information processing system has the effect of enabling unmanned automatic operation, labor-saving automatic operation, and power consumption reduction.
