2. Description of the Related Art Conventionally, a computer such as a personal computer can be terminated by a command from a remote place,
Electronic devices smaller than personal computers generally do not have the capability to interpret and execute such commands. When such a small electronic device falls into an abnormal state such as hang-up or runaway, a person goes to the installation place of the electronic device, shuts off the power once, and then supplies the power again, I try to restore it to normal. An example of such a small electronic device is a data collection device. The data collection device collects data obtained by measuring the temperature and pressure of each facility such as an unmanned device in a factory, and sends the data to the management center.

Further, in recent years, with the spread of the Internet, it has been increasing that these small electronic devices are connected to an IP network such as the Internet or an intranet. In addition, conventionally, some power taps for supplying power to electronic devices are connected to a telephone line, and by raising or lowering a specific pin voltage of a telephone line from a remote place, the electronic device is removed from the power strip. It is known to control the supply of power to the device.

[0004]

Since the above-mentioned data collection device is small and inexpensive, a large number of data collection devices have been installed in a wide range recently, and each device is often connected to a management center through an IP network. It has become to. For this reason, every time the data collection device is in an abnormal state, it is necessary for a person to go to various installation locations and perform a power-off / re-supply operation to restore the device. Therefore, it is possible to recover the power supply of the data collection device in which an abnormality has occurred by operating a specific pin voltage via the telephone line, but it is necessary to prepare a dedicated telephone line for each of many data collection devices.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a power supply control system according to an embodiment of the present invention. This embodiment exemplifies a case where the present invention is applied to a system that supplies power to the above-described data collection device via a power supply device. In FIG. 1, a data collection device 1 installed in a factory is connected to a management server 3 installed in a head office or the like via a network 2 such as an IP network. The data collection device 1 inputs various measurement data measured by various sensors in each facility in the factory, collects these data, and transmits them to the management server 3 via the network 2.

The data collection device 1 is supplied with a power supply voltage from a power supply tap 4 as a power supply device. Power strip 4
Is a power outlet 4 to which the data collection device 1 is connected
1, a power supply control unit 42 that supplies a predetermined power supply voltage to the data collection device 1 via a power outlet 41, a network interface 43 connected to the network 2, a network interface 43, and a management server 3 via the network 2. Communication unit 44 for communication, command interpretation unit 45 for interpreting various signals received via communication unit 44, IP
A memory 46 that stores data such as an address, a user ID, a password, and a control program, and a C that controls the whole
It is composed of a PU 47 and the like. A plurality of data collection devices 1 and power taps 4 may be installed.

The management server 3 communicates with the data collection device 1 and the power supply device 4 via the network 2 and a communication section 3
1, a memory 32, and a CPU 33.

Next, the operation of the above configuration will be described with reference to FIG.
This will be described with reference to the flowchart of FIG. The data collection device 1 constantly transmits the collected data to the management server 3 through the network 2 at a predetermined timing. Here, it is assumed that an abnormality occurs in the data collection device 1 and data transmission is interrupted, and there is no response even when the management server 3 makes an access. When the management server 3 detects that the communication with the data collection device 1 has stopped (step S1 in FIG. 2),
In order to restore the data collection device 1, the power supply of the data collection device 1 is once cut off, and then a power ON / OFF command for performing the operation of supplying again is transmitted to the power tap 4 (step S2).

In the power tap 4, the communication unit 44 receives a signal sent from the management server 3 via the network 2 and the network interface 43 (step S11 in FIG. 3), and from the received signal an IP address or the like. Based on the above, only signals addressed to the own device are selected (step S1)
2). When the signal addressed to the own device is received, the login procedure is performed by collating the user ID, password, etc. (step S
13). Next, it is determined whether the received signal is a power ON / OFF command (step S14).

When the received signal is a power ON / OFF command, the power ON / OFF command is given to the power controller 42. In response to this, the power supply control unit 42 causes the power supply to be supplied to the data collection device 1 via the power outlet 41 to be temporarily cut off and then restarted to be supplied again (step S15). Next, it is determined whether or not the data collection device 1 has been restored (step S16). If the data collection device 1 has not been restored, the process returns to step S5, the power is turned on / off again, and if it is restored, the process ends. In many cases, the data collection device 1 can be restored by this power ON / OFF operation. If the signal received in step S4 is not the power ON / OFF command, the power controller 4
2 performs other control (step S17). Further, in the case of NO in step S16, the restarting operation by turning the power on / off may be performed a predetermined number of times.

In the above-described embodiment, the electronic device supplied with power by the power tap 4 is used as the data collection device 1.
However, other electronic devices may be used.

Next, a program according to the embodiment of the present invention will be described. When the power supply device as the power strip 4 and the management device as the management server 3 according to the above-described embodiment are configured by a computer system, the CPU 4 performs the processing described above with reference to the flowcharts in FIGS.
The programs to be executed by 7 and 33 respectively constitute the program according to the present invention.

As the recording medium, a magneto-optical disk, an optical disk, a semiconductor memory, a magnetic recording medium, or the like can be used, and these may be used by being configured as a ROM, RAM, CD-ROM, flexible disk, memory card, or the like.
In addition, this recording medium holds the program for a certain period of time like a volatile memory such as a RAM in a computer system that serves as a server or a client when the program is transmitted via a network such as the Internet or a communication line such as a telephone line. It includes things to do.

The program may be transmitted from a computer system that stores the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium.
The transmission medium is a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.

The program may be for realizing some of the functions described above. Further, it may be a so-called difference file (difference program) that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
