As shown in (b), a frame in the voice data format is added and transmitted to the base station 6, the signal is received by the portable terminal 8 via the wireless communication I / F 18b, and the data and voice are transmitted to the CP.
The alarm data is separated by the U circuit 17, the alarm data is displayed on the display unit 15, the audio data is converted into an audio signal by the audio processing circuit 19, and an alarm message is generated by the speaker 20.

Further, an on-tour monitoring person inputs a voice message to the microphone 21, converts the voice message into a voice data format by the voice processing circuit 19, and incorporates voice data into a transmission frame by the CPU circuit 17, as shown in FIG. 2 (c). The frame is transmitted to the central monitoring device 1 via the radio base station 6 via the radio base station 6 (the transmission frame between the radio base station 6 and the central monitoring device 1 has the frame format shown in FIG. 2D). A voice message is transmitted to a supervisor on the central monitoring device 1 side by a voice processing circuit (not shown in FIG. 1) of the central monitoring device 1. Similarly, a voice message can be transmitted from a supervisor on the central monitoring apparatus 1 side to a traveling supervisor with the portable terminal 8.

Thus, the central monitoring device 1 converts the contents of the alarm and the monitoring information into voice data, transmits the voice data to the portable terminal 8, and reproduces the voice on the portable terminal 8, thereby displaying the monitoring information. It can also be communicated in a voice message.

(Embodiment 3) Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. 1, 2, 5, and 7A.

In FIG. 1, when an alarm is issued from the central monitoring device 1 as in the case of the first embodiment, a bell (not shown) is sounded and alarm information is displayed on the screen 15 in the same manner. You. In response to this, the monitoring patrol person inputs a control signal for the abnormal part through the key input circuit 16,
The data is transferred to the radio base station 6 according to the data format shown in FIG.

Further, the control signal is transferred from the radio base station 6 to the central monitoring device 1 in the data format shown in FIG. 2 (e), and as shown in FIG. Communication means I by the control means 31
/ F5a to the control device 10 of each facility, whereby the power receiving and distribution facility 11, the lighting facility 12, the air conditioning facility 13,
The pump equipment 22 and the like are controlled.

In this case, even if the central monitoring device 1 does not issue an alarm, if an observer who is traveling around discovers an abnormality, it is also possible to control each facility on site.
Therefore, the portable terminal device 8 can be used instead of the on-site operation panel 35 operated on the site, and the on-site operation panel 3 can be used.
5 and its wiring can be dispensed with.

When the control signal to the electric equipment in the premises is input to the portable terminal 8 in this way, the input content is displayed on the portable terminal 8. Next, the control signal of the electrical equipment in the premises input to the portable terminal 8 is transmitted to the central monitoring device 1 via the radio base station 6, and the central monitoring device 1 transmits the control signal from the portable terminal 8 to the premises. By converting the control command into a control command for the electrical equipment and issuing a control command to the equipment on the premises to perform the control, the monitoring personnel on patrol can control each equipment without returning to the central monitoring device 1 side. it can.

Further, if the monitoring information of the controlled electrical equipment is displayed on the portable terminal 8 via the radio base station 6, the monitoring patrol in the patrol knows whether or not the contents of the control performed are appropriate. Can be very useful.

(Embodiment 4) A fourth embodiment of the present invention will be described with reference to FIG. 1, FIG. 2, FIG. 6, and FIG.

Next, a control signal for the abnormal part is input by the key input circuit 16, and voice data is input and output by the speaker 20 and the microphone 21, and these are transferred to the wireless base station 6 in a data format shown in FIG. The data is transferred to the central monitoring device 1 in the data format shown in FIG.

The CPU circuit 30 of the central monitoring device 1 processes the audio signal, and sends a message to a supervisor on the central monitoring device 1 side. The voice message is transmitted from the supervisor to the supervisor at the site in a procedure reverse to the above-described transmission path, and the message can be exchanged in both directions.

When the on-site supervisor controls each facility, the control data transmitted simultaneously with the voice data in FIGS. 2 (g) and 2 (h) is transmitted to the central monitoring device 1 shown in FIG. 7 (b). Is displayed by the display means 32 from the CPU circuit 30 of the central monitoring device 1 to confirm whether or not the control is possible. If possible, the confirmation command is inputted by the setting means 4 and the control command is transmitted by the control means 31. Do, wired communication I / F5
The control device 10 controls the power receiving / distributing equipment 11, the lighting equipment 12, the air conditioning equipment 13, and the pump equipment 22 via a and 5b. When there is no observer, remote control can be performed unattended only when remote control permission is set.

In this way, when the control is performed by issuing a control command to the electric equipment in the premises, the monitoring information of the controlled electric equipment is displayed on the portable terminal 8 via the radio base station 6 and is transmitted by a voice message. Can also be transmitted.

As is apparent from the above four embodiments, according to the remote monitoring system of the present invention, when an abnormality occurs in the electrical equipment in the premises, a monitoring person patroling the site uses the portable terminal 8. It is possible to immediately know the details of the occurrence of an abnormality and to perform emergency processing from the site. Further, more detailed information can be obtained by voice message, and the central monitoring device 1
You can also have a voice conversation with the side guards.

Further, the on / off of the equipment which had been required to be operated by the on-site operation panel 35 can be operated from the portable terminal 8, and the on-site operation panel 35 and its wiring can be made unnecessary. The monitoring function can be prevented from being stopped, and maintenance is unnecessary.

Further, the voice data transmission function enables the monitoring of the on-site operation panel 35 while the monitoring personnel at the site and the central monitoring device 1 confirm by voice.

[0048]

As is apparent from the above description, the first remote monitoring system of the present invention compares the set upper limit value and lower limit value with the monitoring information from the electric equipment, and sets the monitoring information. By sending a signal to the portable terminal via the wireless base station when the value is out of the range, even if the supervisor is not at the central monitoring device side, the supervisor can be quickly notified and monitored. A member can immediately know that an abnormality has occurred.

In the second remote monitoring system according to the present invention, since the portable terminal issues an alarm, the occurrence of an abnormality can be immediately recognized without the need for the observer to check the portable terminal.

In the third remote monitoring system according to the present invention, the portable terminal displays the monitoring information of the electric equipment.
It is possible for the observer to know the contents of the abnormality on the spot without returning to the central monitoring device.

Further, the fourth remote monitoring system of the present invention can know more detailed information contents by transmitting the monitoring information of the electric equipment as a voice message.

Further, the fifth remote monitoring system of the present invention can control the electric equipment by operating the portable terminal without returning to the central monitoring device.
