The present invention aims to expand the scope of application in industrial field and remote monitoring by easily connecting low-cost system and measuring equipment with various sensors connected to public communication network.

The present invention uses a public communication network such as a general public communication network or a private communication network for the use of a mobile phone, and remotely monitors and monitors various environmental information to a measuring device equipped with various sensors using an input device such as a mobile phone key switch. The technical task is to increase the ease of use, stability and reliability by simply and easily accessing the video and audio transmission / reception terminals provided on the interface cards of mobile phones and PCs to receive information from surveillance equipment and to reduce system construction costs. Do it.

In order to solve the above problems, the present invention connects a mobile phone and a mobile phone to a general public communication network, and connects the mobile phone and a remote control environment monitoring system to a mobile phone, an earphone / speaker terminal, and a remote control environment monitoring system. Control and monitor the bell environment monitoring system.

The remote control environment monitoring system achieves the above problems by analyzing the environmental information of the self and the slave environment monitoring system, converting the information into a DTMF signal or a signal having a DTMF format according to the remote instruction, and adjusting and notifying the voice information. Let's do it.

1 is an overall configuration diagram of the present invention, for monitoring the remote environment monitoring using a public telecommunications network consisting of a public communication mobile phone (1) (3) and a long-term communication network wireless relay device (2).

Connect the monitoring instruction device 4 to the earphone / speaker terminal (handfree terminal: not shown) provided in the cellular phone 1 for public communication, and attach the monitoring main device 5 to the earphone speaker jack of the cellular phone 3 for public communication. Connect. Surveillance main unit (5) is 1,2,... For independent or expansion. … Monitoring slave unit 5A, 1,2,... … The N-dependent monitoring device 5A monitors the environment through a separate wireless device through communication, and according to the instructions of the monitoring main device 5, the individual monitoring devices send out environmental data according to the instructions of the monitoring main device 5; Receive instructions.

The cellular phone 1 for public communication is connected to an earphone speaker jack of the cellular phone 1 and an earphone speaker jack of the monitoring indicating device 4 by a wireless communication device aka cellular phone that can be used in a public communication network.

As shown in Fig. 2, the monitoring instructing device 4 transmits a terminal 45, a DTMF generator 42, a DTMF detector 43, a key 45 for instructing the display device 44, and a sound. The speaker 46, the charging device 47, and the one-chip microcomputer 48 for making out are comprised.

In addition, the earphone / speaker terminal of the cellular phone 3 for public communication and the terminal terminal 51 of the monitoring main device 5 are connected, and the monitoring main device 5 is a terminal terminal as shown in FIG. 3. High-frequency transceiver 56 for wireless communication between 51 and DTMF generator 52, DTMF detector 53, motion display device 54, buzzer 55 for outputting sound, and separate slave monitor 5A. And a dip switch 57 for device identification, a charging device 58, and a one-chip microcomputer 59.

Further, the separate slave monitoring device 5A can be expanded to N by setting the device identification dip switch 57, and the separate slave monitoring device 5A is a high frequency transceiver 5A-1 and a one-chip microcomputer 5A-2. ), The display device 5A-3, the setting input keys 5A-4, the charging device 5A-5, the sensor connection terminal 5A-6, and the device identification dip switch 5A-7. In the above, the system configuration comprises a monitoring remote control environment monitoring system 4 and the monitoring main device 5 as a basic remote control environment monitoring system, and also includes a monitoring main device including the monitoring command device 4 and the subordinate monitoring device 5A ( 5) also constitutes a remote control environment monitoring system.
