Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram of an environment measurement data display transmission device 1 according to an embodiment of the present invention.

In FIG. 1, environmental measurement signals from the water quality meter 2, the process sensor 3, the environmental analyzer 4, and the multimedia sensor 5, which are industrial sensors, are input to a control operation unit 6, which controls the operation. At 6, the data is stored in the data storage unit 7 after necessary calculations and is displayed on the display unit 9 as necessary.

The water quality meter 2, the process sensor 3, the environment analyzer 4, and the multimedia sensor 5 are arranged outside the environment measurement data display transmission device 1 in the illustrated example. Measurement data display transmission device 1
It may be built in.

The environmental analyzer 4 is an analyzer for atmospheric, noise, weather, etc., the process sensor 3 is a sensor for flow rate, water level, water temperature, water pressure, etc., and the multimedia sensor 5 is an image, It is a sensor for voice and the like.

Also, according to the clock signal in the control operation unit 6, the measurement data is output from the control operation unit 6 at a predetermined time, and the radio transmission unit 11 and the radio antenna 15 transmit the telephone data via the signal transmission unit 8. The data is transmitted to the central monitoring center via the line 17. That is, by periodically storing the measurement data in the data storage unit 7 and transmitting the accumulated data intermittently, the power consumption is reduced, and the required capacity of the solar cell 12 and the storage battery 14 is reduced. do it,
The overall size of the device 1 is reduced.

When satellite communication is used, the measurement data is transmitted from the signal transmission unit 8 to the central monitoring center via the satellite antenna 16 via the satellite communication transmission / reception unit 10.

On the other hand, as a power source for driving these devices, the power generated by the solar cell 12 is the power source unit 1.
After the storage battery 14 is charged via the power supply 3 and a part thereof is converted into stabilized power via the power supply unit 13,
Supplied to each device.

When the power generated by the solar cell 12 cannot be obtained due to nighttime or rain, the power stored in the storage battery 14 is supplied to each device, and stable power is always supplied.

FIG. 2 is a diagram showing an internal configuration of the power supply unit 13 shown in FIG. In FIG. 2, the power generated by the solar cell 12 is stored in the storage battery 14 via the diode 36, and is controlled to a stable voltage by the DC-DC converter 19, and is supplied to each unit from the power supply terminal 21. When the output of the solar cell 12 decreases, power is supplied from the storage battery 14 to each unit via the power supply terminal 21. In this case, the rectifying action of the diode 36 cuts off the solar cell 12 side, thereby preventing the power of the storage battery 14 from being discharged by the solar cell 12.

If the power generation of the solar cell 12 is stopped for a longer period than expected, the storage battery 14 is completely discharged, and the output voltage of the storage battery 14 drops (the output voltage of the storage battery 14 becomes lower than the normal operation limit voltage). (When the above specified voltage is reached)
The power supply abnormality signal is output from the power supply abnormality signal output terminal 22 to the control operation unit 6 by the operation of the abnormality detection circuit (voltage monitoring means) 20, and the control operation unit 6 Predetermined calculation on the microcomputer side in the
After storing and signal transmission, the data is saved, the transmission process of the signal transmission unit 8 is interrupted, and a standby state is set.

In this way, it is possible to automatically return to the normal operation when the power generation of the solar cell 12 is started again. When viewed from the central monitoring system, the data display transmission for environmental measurement is performed. Although the data transmission may not be performed temporarily, the device 1 can autonomously transmit data without causing a failure to the monitoring system.

This is effective when operating in a snowy season where the sunshine hours are short or in an urban area where the sunshine hours are short, and when the capacity of the storage battery 14 cannot be large due to restrictions on weight and volume. Although data transmission may not be performed temporarily, data accumulated up to that time is transmitted collectively during sunshine, so that data loss when viewed from the central monitoring system is extremely small.

When it is necessary to rapidly charge the discharged storage battery 14, the external commercial power supply terminal 23
-Continuous operation is possible by supplying and charging external power to the storage battery 14 via the DC converter 18.

The external dimensions are, for example, a height of 1 to 1.5 m and a width of 3
It is about 0 to 50 cm and about 30 cm in depth.

While this embodiment shows an example of installation on the ground, another example of installation is shown in FIG. The attachment is an example using the U bolt 36, but it is needless to say that other means such as a metal band can be used.

The data display unit 9 is preferably a solid-state display device such as a liquid crystal display, an LED, and a plasma display. The upper part of the data display part 9 displays the current time, and the lower part shows the turbidity of water, the content of NOx in the air, and the noise level, which are the measured values of the sensors 2, 3, 4, and 5. it's shown.

The public information display section 34 is a display for displaying public information. It is desirable to minimize the contents to be displayed in order to maintain the beauty of the city and to provide necessary and sufficient information. ing. This gives that one solution. In the illustrated example, a lot number, a place name, a station name, and the like are displayed.

It is. In addition, emergency guides, instructions and traffic information display or daily publicity,
It is useful as information providing means for public use such as weather information.

For example, if the measured values of the sensors 2, 3, 4, 5 are normal values, the current time and the measured values are displayed on the display unit 9 as shown in FIG. Then, the display unit 34 displays a lot number and the like.

When the measured values of the sensors 2, 3, 4, and 5 become abnormal values, as shown in FIG. 7, the contents of the abnormality are displayed on the display unit 9 and the display unit 34 displays them. Display warning, caution and warning messages. The example shown in FIG. 7 is an example in the case of water quality deterioration.

When the water supply manager patrols each installation point of the environment-measurement data display transmission device 1, the display unit 34
If the operator notices an abnormality such as water quality from the display and wants to check the water quality and operation state of the water purification plant, the water quality and operation data of the water purification plant wirelessly transmitted are displayed on the display unit 34 as shown in FIG.
