Abstract

PURPOSE:To start actual processing at a fixed time by setting the time which has subtracted the time required for the system-up of the previous time from the processing start time, as the power source turning-on time of the next time. CONSTITUTION:A reservation start time of the next time stored in an MEM420 of a system controller 4 is read out by a BM430, the time required for the pre- processing of the previous time is subtracted from said time by an ALU401, and a power source turning-on time of the next time is derived and stored in a timer register (TMR)630. When the time of a real time clock (RTC)620 of a timepiece device 6 becomes the same time as the TMR630, a comparator (CMP)640 sends a start command to a power source device 1. When an operator executes a reservation of an automatic power source start so as to match the operation start time of the processor, the actual processing can be started at the fixed time.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an automatic power-on system, and in particular, after power-on,
The present invention relates to an automatic power-on method suitable for a processing device that requires a long time for initial settings for starting operation, such as initial program loading and importing host data via a communication line.

[Background of the invention]

Conventional automatic power-on systems generally use a so-called time switch system in which the power-on time is set in a timer and the device is powered on at that time. However, in electronic computer systems and the like, after the power is turned on, the actual operation cannot be started unless initial program loading, system program loading, etc. are completed. Therefore, in order to start work on time, the startup start time must be set in consideration of the time from power-on to system startup, which is cumbersome. In addition, if data transfer with other devices is required after power-on, the preprocessing time after power-on differs depending on the device, so the data transfer start time will not match, and in the end, the longest time will be used. It is also necessary to set a startup start time, and as a result, there is a problem in that the time required to start actual processing becomes longer and the operational efficiency of the system decreases.

[Purpose of the invention]

An object of the present invention is to provide an automatic power-on method that can start actual processing at a set time in a computer system equipped with an automatic power-on mechanism.

[Summary of the invention]

The present invention measures the time from when the power is turned on until the processing device starts actual processing each time the power is turned on, and when the power is turned on next time, the processing device starts the actual processing from the previous power-on. By subtracting the time until the next power is turned on, the actual processing can be started on time.

[Embodiments of the invention]

FIG. 1 shows a configuration diagram of an embodiment of the present invention. In the figure, the power supply device 1 is a main power source (MAIN-P) that starts up in response to a startup command.
S) 2 and an auxiliary power supply (SUB-PS) 3 that continues to supply power even during para-off. The output of the main power source 2 is supplied to a system controller 4 that performs main control of the device. The system controller 4 includes a central processing unit (CPU) 41 having a central processing unit (ALU) 401.
0. A storage device (MEM) 420 that stores the control program of the CPU 410 and the processing start time. A buffer memory (BM) 430 that stores a primary start time among the process start times stored in the MEM 420. An input/output control mechanism (I) that controls input/output devices that operate under the control of the CPU 410
OC)440. and a data control mechanism (CMA) 450 that controls data transfer with other systems.

moreover.

A keyboard 5 is connected to the CPU 410 of the controller 4 for reserving a process execution start time in the MEM 420.

The clock device 6 issues a startup command to the power supply device l at a scheduled time, and receives power from the 5UB-PS3.
It continues to operate even when the power supply to the device l is off. This clock device 6 includes a timer (TMG) 610. which outputs a signal in seconds using an oscillator. A real-time clock (RTC) 6 that receives the output signal of the TMG 610 and reports the current time.
20, a timer register (TMR) 630 that receives the calculation results of the ALU 401; A comparator (CMP) 640 compares the times of the TMR 630 and RTC 620, and if they match, issues a startup command to the power supply 1.The comparator (CMP) 640 takes a set state with the startup command of the CMP 640, and after the system is started, various preprocessing is completed. When the system is ready for actual use, the flip-flop (FF) 650 returns to the reset state upon receiving a signal from the CPU 410, and upon receiving a set signal for the FF 650, it starts measuring time using the second unit signal from the 7MG 610, and the FF 650 When the reset state is reached, the clock counter (CL) stops measuring time and sends the measured time to ALU401.
C) consists of 660.

The operation will be explained below. Now 2 clock device 6 RTC62
The current date and time announced by 0 is February 16, 1984, 8:44.
Minutes and 40 seconds. On the other hand, ME of system controller 4
M420 stores reservation processing start dates and times for several days that have already been entered from the keyboard 5 (here, data transfer start dates and times with other systems), and the first start date and time is l^tsAIv! The next start date and time is 19.
Assume that it is February 17, 1984, 8:00:00:00. Also.

It is assumed that the time required for the previous preprocessing was 15 minutes, the 15 minutes were subtracted by the ALU 401 from the contents of the BM 430, and 8:45 o seconds on February 16, 1984 was stored in the TMR 630.

Now, the clock device 6 is always operating by the 5UB-PS3 of the power supply device 1, and the time of the RTC 620 advances by the seconds signal from the 7MG 610.

When the time of the RTC 620 becomes the same time as the TMR 630, that is, 8:45:0 on February 16, 1984, the C
The MP 640 sets the FF 650 and sends a start command to the power supply device 1. Since the FF 650 is set, the CLC 660 inputs the second unit signal of the 7MG 610 via the AND gate 15' and starts timing. The power supply device 1 is set to MAIN-P by the startup command from CMP640.
S2 rises and the system controller 4 enters the operating state. As a result, the system controller 4
0 from an input device (not shown), and when the initial processing is completed, the CPU 410
sends a reset signal to the FF 650 of the clock device 6. The FF650 is reset by this reset signal, and the CL
C660 timekeeping stops. Thereafter, the CPU 410 of the system controller 4 starts data transfer with other remote systems via the CMA 450.
Assuming that the timer was 15 minutes as before, the CPU
At 410, data transfer starts at 9:00:00 as scheduled.

When the data transfer with other systems is completed, the CPU 410
is the start date and time of the next data transfer from MEM42019
Read 8:00:00 on February 17, 1984 to BM430. The 15 minutes clocked by CLC660 is subtracted from the contents of this BM430 by ALU401, and the resulting 1984
February 17, 2018 7:45:00 is set in TMR630. As a result, the next time will be on February 17, 1984 at 7:45.
At minute 0 seconds, the power supply bag! 1 MAIN-PS2 started up, preprocessing was completed in 15 minutes, and there was no waiting time between systems, and the time was 8:00 on the 2nd and 17th, 1984.
Data transfer with other systems will begin in seconds.

The above explanation has been given using an example of a system configuration in which data is transferred between other systems after the power is turned on and preprocessing is completed. However, the present invention can be widely used in other systems or devices having an automatic power-on mechanism. It is possible to do so.

〔Effect of the invention〕

According to the present invention, the time required for preprocessing after powering on the processing device is automatically subtracted and the power is turned on automatically.
The operator only has to schedule automatic power start-up in time with the start time of the processing equipment, which reduces the hassle of operating the processing equipment, and also eliminates waiting time and starts actual processing on time. As a result, the operational efficiency of the system can be improved, and as a result, power consumption can be reduced.
