This is a remote automatic power supply control device configured to enable information exchange between the

According to the present invention, it is possible to automatically power on information processing equipment at the center from a remote terminal device,
This has the effect of making it possible to make the center unmanned and at the same time realizing safe and reliable power-on.

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 is a block diagram showing an example of the relationship between various devices in a center when the present invention is implemented, and FIG. FIG. 2 is a block diagram of an embodiment of a control device.

The embodiment shown in FIG. 1 includes: a remote automatic power supply control device 1; a status detection circuit for ancillary equipment including a computer system; 2; power supplies 3 and 4; and information processing equipment 5. The information processing device 5 in this device is supplied with DC current from the power supply device 4 via the connection line 108, and when it becomes operational, it sends an operation enable signal to the remote automatic power supply control device 1 via the connection lines 1 and 0. It also sends and receives data to and from the remote automatic power supply control device 1 via the connection line 109, and processes the data. Power supply device 4 is remote automatic power supply control device 1
receives a power-on signal from the computer via the connection line 106, supplies direct current to the information processing equipment 5 via the connection line 108, and supplies the remote automatic power control device 1 via the connection line 107.
Sends a power-on start signal to suppress a power-off signal to the The power supply device 3 connects the remote automatic power supply control device 1 to the connection line 1.
03, supplies alternating current to the power supply device 4 via connection #105, and starts powering on the remote automatic power control device 1 via connection line 104 to suppress the power cut signal. Send a signal.

A state detection circuit 2 for ancillary equipment including information processing equipment constantly sends out a state signal for the ancillary equipment to the remote #power supply control device 1 via a connection line 102.

FIG. 2 is a block diagram showing one embodiment of the remote automatic power control device 1 according to the present invention. In the figure, 6 is a modem signal control section, 7 is a data receiving section, 8 is a data transmitting section, 9 is a request message processing section, and signal lines 101 to 1
04, 106 to 107, and 109 to 110 correspond to the signals with the same symbols in FIG. 1, respectively.

Figure 3 shows the format of an example data text indicating a power-on request message from a remote terminal.
X is the start character of the text, SA and UA are the addresses of the calling station and equipment, respectively, ID is the calling number, and C
MD indicates a command indicating a power-on request, and ETX indicates a text end character.

Figure 4 shows the format of an example of a data text indicating a response to the sender, where 8TX is the start character of the text, ST8 is a message indicating the power-on status and signal status from the auxiliary equipment status detection circuit 2, and ETX is the end of the text. It shows the characters.

Next, the operation will be explained using these FIGS. 1, 2, and 3. Communication line 101 from a remote terminal device (not shown)
When the message shown in FIG. 3 is sent to the computer system at the center to request power-on of the computer system via the modem signal controller 6.
The data is input to the request message processing section 9 via the data receiving section 7. When the message shown in FIG. 3 is input, the request message processing unit 9 checks the SA and UA, and compares these addresses with the addresses of the source station and device registered in advance. After confirming that the addresses of these 8A and UA and the pre-registered calling station and device match, then compare the ID part in Figure 3 with the pre-registered caller number. do. When it is confirmed that the ID part matches the pre-registered caller number in parentheses, the request message processing unit 9 connects the connection line 102 from the auxiliary equipment of the information processing equipment and the state detection circuit 2 of the information processing equipment. It is checked to see if it is in a preset normal state, and if it is determined to be abnormal, a message is sent to the sender via the data transmitter 8 and the modem signal controller 6 in the format shown in Figure 4. A code indicating an abnormal condition is sent as STS. As a result, subsequent power-on operations are prohibited.

Next, it is checked whether the connection line 102 from the state detection circuit 2 is in a normal state, and if it is determined that there is no abnormality, a power-on signal is sent to the power supply device 3 via connection #103, and the connection line While supplying alternating current to the power supply device 4 via 105.

A power-on start signal for suppressing a power-off signal is sent via the connection line 104. When it is determined that the signal from the state detection circuit 2 is not abnormal, the request message processing unit 9
sends a power-on signal to the power supply device 4 via the connection line 106, supplies DC current to the information processing equipment 5 via the connection line 108, and sends a power-off signal to suppress the power-off signal via the connection line 107. Sends a power-on start signal. When it is determined that the signal from the state detection circuit 2 is not abnormal,
The request message processing unit 9 confirms via the connection line 110 that the information processing device 5 is operational.

Data is exchanged with the information processing device 5 via the connection line 109.

As explained above, according to the present invention, it is possible to safely input m sources from a remote terminal device to information processing equipment in a center, and to perform unmanned labor-saving automatic operation and remote monitoring operation of an information processing system.
