DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment according to the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram for explaining a remote monitoring control method using a mobile phone terminal according to the present invention. 1, an A / D converter 12 for inputting a detection signal from a temperature sensor 10 and converting it into digital data, a relay circuit 13 for turning on / off a power supply of a power supply control device 11, and a Web server 14
And the Ethernet interface 15 is housed in the first supervisory control device 1. The first monitoring and control apparatus 1 is connected to the router 3 via the Ethernet 22, and the router 3 is connected to the Internet 5 via the communication line 24.

The second monitoring and control device 2 has a temperature sensor 16
An A / D converter 18 for inputting a detection signal from the converter and converting it into digital data, and a power supply of a power supply control device 17 are turned on.
A relay circuit 19 for turning off and an SNMP control function 20
And an Ethernet interface 21. The second monitoring and control apparatus 2 is connected to the host computer 4 having a built-in Web server via the Ethernet 23, and the host computer 4 is connected to the Internet 5 via the Ethernet 28, the router 27 and the communication line 25. It is.

[0007] Since the Internet 5 is connected to the mobile phone base station 6 via a communication line 26, the mobile phone terminals 7 and 8 corresponding to the Internet service are connected to the Internet via the mobile phone base station 6 by wireless communication means. 5
Connected to. Accordingly, the mobile phone terminals 7 and 8 are connected to the temperature sensor 10 and the power supply control device 11, which are the monitoring control targets of the first monitoring control device 1 connected to the Internet 5 via the router 3, and the router 27 and the host computer. It is possible to remotely monitor and control the temperature sensor 16 and the power supply control device 17 that are the monitoring and control targets of the second monitoring and control device 2 connected to the Internet 5 through the Internet 4.

As is clear from the above description, the first supervisory control device incorporating a Web server is connected to the Internet via a router, but the second supervisory control device not incorporating a Web server is It is connected to the Internet via a host computer with a built-in Web server and a router. When a plurality of monitoring and control devices are integrated and connected to the Internet, a method of connecting to the Internet via a host computer with a built-in Web server can simplify the overall system configuration.

FIG. 2 is a flowchart in the case where the first monitoring control device 1 is remotely monitored and controlled using a portable telephone terminal. When the status is displayed, the target device is selected and called, and then the status is displayed on the display of the mobile phone terminal in steps S1 to S5. That is,
Analog data (for example, temperature sensor 10) called and selected from the mobile phone terminal is collected (Step S).
1) The collected analog data is converted into digital data in the A / D conversion circuit 12, and the Web server 14
HTML (Hyper Text Markup)
Language) is generated (step S2). At this time, if it is determined that the program of the monitoring control device is calling the monitoring control device from the mobile phone terminal, the mobile phone terminal HTML is generated. Next, a message described in HTML is distributed by a Web server built in the first monitoring and control apparatus 1 (step S3). The message is input to the router 3 via the Ethernet interface 25 and sent to the Internet 5 via the communication line 24 (step S4). Communication line 26 on Internet 5
The telegram input to the mobile phone base station 6 connected via is displayed on the display of the mobile phone terminal 8 via wireless communication means (step S5).

When performing device control, a method of calling a device to be controlled (for example, the power supply control device 11) and displaying the status of the device on the mobile phone terminal 7 is performed by steps S1 to S5. Next, the device is controlled by steps S6 to S8. That is, the operation of the operation switch displayed on the display is taken into the Web server 14 by CGI (Common Gateway Interface) (step S6), and the Ethernet 22
Control information (for example, a DO control signal) is transmitted through the control unit (step S7), and the control target device (for example, the relay circuit 1)
9) is turned on (step S8).

FIG. 3 is a flowchart in the case where the second monitoring and control device 2 is remotely controlled. To display the status,
After selecting and calling the target device, the status is displayed by the steps from step S10 to step S16. In the case of device control, a target device is selected and displayed on the display of the mobile phone terminal in steps S10 to S16, and then the device is turned on and off in steps S17 to S21.
Control OFF and display on display.

First, after selecting the temperature sensor 16, analog data is collected (step S10), the collected data is converted into digital data, and then the SNMP (Simple Network Management Protocol) of the monitoring and control device 2 is used.
The data is transmitted by the control function (step S11), the SNMP data is interpreted in the host computer 4 (step S12), and HTML is generated from the data (step S13). If it is determined that the calling is the mobile phone terminal, the mobile phone terminal HTML is generated. Next, a message described in the HTML format for the mobile phone terminal is distributed by a Web server built in the host computer 4 (step S14), and is displayed on the display of the mobile phone terminal compatible with the Internet via the Internet (step S15). The data of the temperature sensor 16 is displayed (Step S16).

When the power control device 17 is selected, the power control device 17 is selectively displayed on the display of the portable telephone terminal in steps S10 to S16. Next, the operation of the operation switch displayed on the display is taken in by the CGI function of the Web server built in the host computer 4 (step S17), and the data is transmitted to the second monitoring control device 2 by SNMP (step S18). . The second monitoring control device 2 interprets the received data by SNMP (step S19), and turns on the relay (step S21) by DO control (step S20).

[0014]

As described above, according to the present invention, information transmission and device control using the Internet are performed by a simple operation of a mobile phone terminal compatible with the Internet service. Monitoring and control of the target device can be performed. In addition, since the information is displayed on the display of the mobile phone terminal, the monitoring control method is very simple.
