To output the operation contents. The smartphone 1 also has a communication function (communication with the Internet) 110 that can be connected to an Internet line, and can obtain weather data via the Internet, for example.
In this way, the monitoring and control personal computer 60 can remotely monitor and control the devices and the sensors 3.

  The operation contents from the smartphones 61 and 62 are transmitted to the smartphone 1 via the screen function 121, the monitoring control function 122, the communication function (communication with the smartphone 1) 120, and the communication network 31 of the smartphones 61 and 62. . In the smartphone 1, the operation content is received by the communication function (communication with the smartphones 61 and 62) 113, and the operation content is transmitted from the communication function (communication with the interface device) 111 to the interface device 2. The flow of signals from the interface device 2 to the devices and the sensor 3 operates in the same manner as the remote monitoring control from the monitoring control personal computer 60.

  With the above configuration, the amount of information that can be transmitted and received can be increased. Further, the operator can operate the system at the cost of purchasing and running the smartphone, so that the system can be constructed relatively inexpensively, and the system can be constructed in a shorter time.
