Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a power supply control device for a computer built-in device.

(Prior Art) With the recent dramatic progress of electronic technology, various works and processes tend to be performed by devices with built-in computers.

At night or the like, work that does not normally need to be operated by humans is automatically performed using a device with a built-in computer, and the device can be operated in an unmanned state, thereby improving work efficiency. For example, when receiving certain data and using it to analyze phenomena, basically humans need data in the middle of analysis, analysis results, etc. In this case, the work time is unnecessary for humans.

In addition, when performing a routine work, the work is repeated the same work, so that when a person performs this work, a work mistake or forgetting work tends to occur. On the other hand, the stylization process is the greatest advantage for the computer, and it can be expected that the task can be reliably performed by using the computer built-in device for the above-described routine task.

By the way, when such a device with a built-in computer is used, it is preferable that the power of the device is turned ON / OFF by a power supply control device such as a timer switch instead of continuously operating the device for the following reason. That is, at the same time as the necessary processing is completed, the power of the device is turned off, so that the power consumption can be reduced and the power bill can be saved.

Assurance of equipment life When a so-called personal computer is used as a computer with built-in equipment, the personal computer and its peripheral devices are not generally rated continuously. Often adversely affects durability. Therefore, by turning on the device only when necessary, the durability of the device can be guaranteed.

Various types of power supply control devices have conventionally been used in this type of computer built-in device. For example, Japanese Patent Application Laid-Open Nos. 59-16240, 61-254886, and 1-1
There was one disclosed in Japanese Patent No. 22536 and the like.

(Problems to be solved by the invention) However, in the conventional power supply control device, it is necessary to separately provide a CPU or the like for controlling the opening and closing of the power supply circuit, and to always keep the power supply in the power supply circuit. However, there was a problem that the cost was high.

On the other hand, as a method of solving such a problem, a method of controlling the opening and closing of the power supply circuit using a computer built in the equipment can be considered.In this method, the power supply circuit is turned on when the equipment is turned on from the OFF state. Since ON control cannot be performed, the problem is how to solve this.

In view of the above problems, it is an object of the present invention to provide a power supply control device for a device with a built-in computer that can control ON / OFF of a power supply circuit for the device by using the computer with a built-in device.

(Means for Solving the Problems) Therefore, the power supply control device for a device with a built-in computer according to the present invention is provided in a device with a built-in computer that performs a predetermined process by a built-in computer, and operates according to a command from the computer with a built-in device to operate the computer. What is claimed is: 1. A power supply control device for controlling supply of power to a device, comprising: a power supply circuit for a device as a power supply for the device with a built-in computer; a relay contact with a latch function connected in series in the power supply circuit for the device; A switching circuit including an ON relay that closes the relay contact with the latch function at the time when the next connection operation time data of the ON relay of the switching circuit is provided in the computer with the built-in device and the computer built-in device is operating. The data generation means keeps the time in a regular clock while the time data generation means A timer circuit including a first timer that activates the ON relay of the switching circuit at a time corresponding to the input next connection time data, and a power supply circuit that constantly supplies power to the switching circuit and the timer circuit. .

Here, the disconnection of the device power supply circuit may be performed directly by the device built-in computer because the device is in operation, or may be performed using the power supply control device of the present invention. That is, when the power supply circuit for equipment is directly disconnected by the computer with built-in equipment, a disconnection signal generating means is provided in the computer with built-in equipment to generate a cut-off signal for the power supply circuit for equipment, and the cut-off signal is latched by a latch circuit. The switching circuit may be turned off by the latch circuit, and the latch circuit may be always energized by the power supply circuit.

When disconnecting the power supply circuit for equipment using the power supply control device of the present invention, the switching circuit is provided with an OFF relay for opening a relay contact with a latch function by its operation, and the time data generation means is further provided with an OFF relay. A function to generate the OFF operation time data of the OFF relay of the switching circuit is provided during the operation of the built-in computer device, and the timer circuit keeps the clock at a regular time while the time corresponding to the disconnection time data input from the time data generating means. And a second timer for activating the OFF relay of the switching circuit.

(Operation) In the present invention, the switching circuit and the timer circuit are always energized by the power supply circuit, and when the next connection operation time data of the switching circuit is output from the time data generating means while the device is ON, this is transmitted to the timer circuit. When the time corresponding to the above time data comes after the device is turned off, the timer circuit causes the switching circuit to perform a connection operation, whereby power is supplied from the device power supply circuit to the computer built-in device, and thus the device built-in device is turned on. The computer is turned on by the computer.

Further, if the timer circuit is further provided with a disconnection operation function of the switching circuit and the disconnection operation time data is generated from the time data generation means during operation of the device, all ON / OFF operations of the device are automatically performed.

Further, when a disconnection signal is generated from the disconnection signal generating means, the disconnection signal is latched by a latch circuit, and the switching circuit is directly operated to disconnect by the latch circuit.
The power is not automatically turned off during the work of the equipment for an indefinite period of time.
You can do it.

(Example) Hereinafter, the present invention will be described in detail based on a specific example shown in the drawings.

FIG. 1 shows a power supply control device for a computer built-in device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a personal computer (equipment with a built-in computer) that has a data bus 10 and an I / O bus 11 of an expansion slot and performs predetermined processing. Commercial power supply 2
0, a fuse 21, an outlet 22, and a forcible switch 23.

Reference numeral 3 denotes a switching circuit for connecting and disconnecting the power supply circuit 2 for the device, which is a relay contact 30 with a latch function connected to the power supply circuit 2 for the device and ON and OFF for opening and closing the contact.
It is configured by relays 31 and 32.

Reference numeral 4 denotes a timer circuit that counts the time and connects / disconnects the switching circuit 3 in accordance with time data input from the outside. The timer circuit 4 includes first and second timer ICs 40 and 41 and ON / OFF of these. It is constituted by dip switches 42 and 43 selectively connected to the relays 31 and 32.

5 is provided in the personal computer 1, and the forcible switch 23 is provided.
The time data generating means for outputting the disconnection operation time data of the switching circuit 3 and the next connection operation time data to the data bus 10 of the expansion slot at the start of the automatic operation of the personal computer 1 when the computer 1 is turned off. Disconnection signal generating means for outputting a relay OFF signal (disconnection signal) to the I / O bus 11 in response to the signal; a latch circuit 6 for latching the relay OFF signal from the disconnection signal generating means 8 and supplying this to the relay 32; Outputs 5V DC with commercial power supply 20 as input.
Switching circuit 3, timer circuit 4, and latch circuit 6
Is a power supply circuit that constantly supplies current to the power supply. Note that an internal battery may be provided in the power supply circuit 7 as a measure against a power failure.

FIG. 2 shows an example of a schedule creation flow in this apparatus, and FIG. 3 shows an example of an alarm setting flow.

 Next, the operation will be described.

If the relay contact 30 is turned on when the forcible switch 23 is turned off, a commercial current flows through the power supply circuit 2 and the power supply line 11 of the personal computer 1 to the personal computer 1, and the personal computer 1 is turned on and in the automatic operation mode. A predetermined process, for example, automatic reception and analysis of data is performed.

On the other hand, the OFF time and the ON time of the personal computer 1 are input to the storage area in the time data generating means 5, for example, a floppy disk, for each day of the week using the keyboard of the personal computer 1 in advance (see FIG. 2).

When the personal computer 1 enters the automatic operation mode during the operation of the personal computer 1, the time data generating means 5 in the personal computer 1
Outputs the disconnection operation time data corresponding to the processing end time and the connection operation time data corresponding to the next operation start time to the data bus 10 of the expansion slot, and both data are output to the second and first timers 41 and 40. Is entered. The second timer 41 always counts the time, and when the time corresponding to the input disconnection operation time data comes, the OFF relay 32 is operated, and the relay contact 30 turns off the power supply circuit 2 for the device. The personal computer 1 is turned off (see FIG. 3).

Further, even after the personal computer 1 is turned off, the switching circuit 3, the timer circuit 4 and the latch circuit 6 are still energized from the power supply circuit 7, and the first timer 40 always counts the time and inputs the connection operation. When the time corresponding to the time data comes, the ON relay 31 is operated, the relay contact 30 is turned on, the power supply circuit 2 for the device is turned on, and the personal computer 1 is turned on to return to the operating state. (See FIG. 3).

It should be noted that a predetermined time lag can be set in the time data in order to ensure consistency with the operation of the peripheral device of the personal computer 1. For example, when the processing of the personal computer 1 is completed and the analysis result is printed out to the printer, since the operation of the printer is much slower than the processing operation of the personal computer 1, even if the processing of the personal computer 1 is completed, The power supply circuit 2 can be turned off after a certain time lag so that all the analysis results can be printed out.

Also, the PC 1 does not output the cutting operation time data, but can generate an OFF signal (cutting signal) from the cutting signal generating means 8 when the operation of the PC 1 is completed, for example, when necessary, during the operation. The OFF signal is latched by the latch circuit 6, and the OFF relay 32 of the switching circuit 3 is directly operated to turn off the power supply circuit 2. Thus, the power supply circuit 2 is directly turned off by the OFF signal from the disconnection signal generating means 8. Accordingly, even when the personal computer 1 is performing processing for an indefinite period of time, the processing can be completed, and at the same time, the device power supply circuit 2 can be turned off, so that the processing can be performed reliably. Here, the latch circuit 6 is used to hold the signal state of the I / O bus 11 because an extremely short-time signal is output from the I / O bus 11 and the OFF relay 32 cannot be operated as it is. ing.

When the forcible switch 23 is turned on, the relay contact 30
Power is supplied to the personal computer 1 from the power supply circuit 2 regardless of ON / OFF.

When the power supply 2 of the personal computer 1 is automatically turned on as described above, there is a concern that the peripheral device will not be on standby due to a difference in the rise time of the peripheral device, and that smooth processing cannot be performed. For example, when writing data to an external fixed disk, the personal computer 1 may start up earlier than the fixed disk, and the personal computer 1 may not recognize the fixed disk and may determine that the fixed disk is not connected. In such a case, it is desirable that the personal computer 1 be reset by software again so that the fixed disk is recognized.

In the power supply control device of the present embodiment as described above, the power supply of the personal computer 1 is automatically turned on / off by using the personal computer 1, and thus the following effects are obtained.

Saving electricity bills The equipment is turned on and off when needed, reducing power consumption and saving electricity costs. Although the switching circuit 3, the timer circuit 4 and the latch circuit 6 are always energized, the amount of electricity used is significantly smaller than when energizing the control CPU and the like.

Automatic registration of stylized processing The contents to be processed by the personal computer 1 from ON to OFF vary depending on the user, but this device uses the batch processing function of the OS of the personal computer 1 and the mutual connection function of the program language itself, etc. Can be set at random according to the purpose.

Efficiency of use of personal computer Because it is turned on and off when necessary,
Can be used efficiently and effectively, and continuous use can be avoided, so that the life of the personal computer 1 and its peripheral devices can be extended.

Control by instructions from personal computer 1 The computer is not installed in this device, but is operated according to instructions from personal computer 1. Therefore, the cost of this device is not so expensive, and it can be easily operated by ordinary personal computer operation. Power supply can be controlled in various ways.

Use of PC Expansion Slot Since this device is designed as an additional board for the personal computer 1, it can be mounted in the personal computer 1 without requiring much space for installing the device.

(Effects of the Invention) As described above, according to the power supply control device for a computer built-in device according to the present invention, the switching circuit and the timer circuit are always energized, and the time data generating means of the computer in the device is turned on while the device is ON. To output the next connection operation time data to the timer circuit and supply it to the timer circuit.When the computer built-in device is turned off, the timer circuit makes the switching circuit perform the connection operation and the power supply circuit for the device starts energizing the computer built-in device. Therefore, the power of the device can be controlled to be turned on using a computer with a built-in device, and the device can be configured at low cost.

According to the present invention, the time data generating means further generates disconnection operation time data of the switching circuit during the operation of the device, and the timer circuit further generates the disconnection operation time data input from the time data generation means. If the switching circuit is turned off accordingly,
This has the effect of automatically turning on and off all devices.

Further, according to the present invention, a disconnection signal generating means is provided in the computer with a built-in device to generate a disconnection signal for the power supply circuit for the device, the disconnection signal is latched by the latch circuit, and the switching circuit is disconnected by the latch circuit. In this case, there is an effect that the device can be turned off at the same time when the work of the device for an indefinite time is completed.
