Abstract

PURPOSE:To enable residents in an area where a slave station is installed to take a proper countermeasure by deciding whether or not a warning regarding fire occurrence is generated by a decision means provided to the slave station and generating the warning by the warning means of the slave station when necessary. CONSTITUTION:The remote monitor system consists of a sensor 1 which detects data regarding disaster, the slave station equipped with a transmitting means 2 which sends data detected by the sensor 1, and a master station which receives the data sent from the slave station and sends warning information according to the received data. Then the slave station is equipped with the decision means 3 which decides whether or not the warning regarding the disaster occurrence needs to be generated according to the data detected by the sensor 1 and a warning means 4 which sends out the warning to area residents when the decision means 3 decides that the warning needs to be generated. Consequently, the warning is generated without waiting for the warning information from the master station and a proper countermeasure can be taken.

Description

[Detailed description of the invention] [Objective of the invention] (Industrial application field) This invention obtains water level data from a slave station installed near a river, etc., and causes a master station to issue an alarm based on this data. This article relates to a remote monitoring system used to issue warnings for disasters such as disasters.

(Prior Art) In a conventional system of this kind, a master station collects data from slave stations using a telemeter method, and based on this data, a supervisor at the master station determines whether or not it is necessary to issue an alarm. When necessary, alarm information is sent from the master station to an alarm generating device (installed at a slave station or other necessary location), and this alarm generating device generates an alarm.

For this reason, even if there is an actual danger of a disaster occurring in the area where a slave station is installed, it takes time for data collection, analysis and judgment by monitors, and transmission of warning information, making it impossible to take appropriate responses. A problem had arisen.

(Problems to be Solved by the Invention) As described above, in the conventional remote monitoring system, the master station collects data and the monitor makes a judgment before transmitting alarm information. Even if there is an actual danger of a disaster occurring in an area where a warning system is installed, it takes time for a warning to be issued, making it impossible to take an appropriate response.

The present invention was made to solve the problems of the conventional remote disaster monitoring system, and its purpose is to monitor the remote monitoring system when a disaster is imminent in the area where the slave station is located. It is an object of the present invention to provide a remote monitoring system capable of shortening the time until an alarm is issued by making it possible to issue an alarm with only one person.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a slave station that includes a sensor that detects data related to a disaster, a transmitter that transmits the data detected by the sensor, and a mobile station that transmits the data detected by the sensor. It is necessary to issue a warning regarding the occurrence of a disaster to the slave station in the remote monitoring system, which includes a master station that receives the transmitted data and transmits warning information based on this data, based on the data detected by the sensor. A remote monitoring system is provided with a determining means for determining whether or not there is a warning, and an alarm means for sending out a warning to local residents when the determining means determines that it is necessary to issue a warning.

(Function) According to the above configuration, the determination means provided in the slave station determines whether or not to issue a warning regarding the occurrence of a disaster, and the warning is issued when necessary, so there is no need to wait for warning information from the master station. An alarm will be generated without any warnings, allowing appropriate responses to be taken.

(Example) An example of the present invention will be described below with reference to the drawings. Second
The figure is a block diagram of one embodiment of the present invention. In the figure, 100 indicates a slave station, 200 indicates a master station, and 300 indicates a master station.
indicates a local resident's house, and 400 indicates an alarm generating device.

The master station 200 and the slave station 100 are connected by a wireless line using a telemeter system, and the master station 200 and the slave station 100 or the alarm generating device 400 are connected by a wired line for transmitting alarm information. The slave station 100 has an antenna 101 and a transceiver 10.
2. A slave station control device @103 and an alarm device 104 are provided,
The master station 200 is equipped with an antenna 201, a transceiver 202, a master station control device 203, and a speaker 204. The configuration of the slave station 100 is shown in a functional block diagram as shown in FIG.

A sensor 1 detects river water level data and rainfall amount data. 2 is a transmitting means that transmits data obtained by the sensor 1 to the master station 200; 3 indicates the determination means,
The sensor 1 includes a comparator 31 and a threshold data holding section 32.
The data sent from the sensor 1 is compared with the threshold data held by the threshold data holding section 32, and when the data sent from the sensor 1 exceeds the threshold data, the output signal is made active.

This output signal is given to the alarm means 4. The alarm means 4 includes a drive section 41 and a speaker 42. The drive section 41, which is given an active output signal, sends out an alarm sound signal and causes the speaker 42 to generate an alarm sound.

Of the above configuration, the transmitting means 2 is included in the transceiver 102, and the sensor 1 and the determining means 3 are included in the slave station control device 103. The alarm means 4 corresponds to the alarm device 104.

Here, the slave station control device 103 has a configuration of, for example, a microcomputer, and has various parts as shown in FIG. In the figure, 131 is a CPU, 132 is a main memory, and C
P U 131 controls each section based on a program in main memory 132 . Data coming from the sensor 1 is taken into the CPU 131 via the interface 133. The cpU 131 sends the data captured above to the transceiver 102 in a predetermined format. The transceiver 102 transmits data using a telemeter method. C.P.
A keyboard input device 135 is connected to the bus extending from U 131 via an interface 134, and a speech synthesis section 136 is also connected. Threshold value data r1-rn of data coming from the sensor 1 and corresponding alarm information P1-Pn are inputted to the keyboard input device 135. This threshold data r1 to r'n and alarm information P1 to P
o is stored in association with the main memory 132. When the voice synthesis unit 136 receives the alarm information P1 to P, it synthesizes the corresponding voice to generate and output a voice signal. For this reason, the threshold data r1 to rn are made to correspond to each stage of the warning.
By inputting Po from the keyboard input device 135 in advance, the main memory 1
32, the alarm information screen~Po is shown.

In the slave station 100 configured as above, the CPU 131
takes in data from sensor 1 via interface 133 and compares it with threshold data r1-ro. If it does not exceed any of the threshold data r1 to r, CP
The jJ 131 stores the captured data in the main memory 132 and transmits it via the transceiver 102 when the master station 200 collects data using a telemeter method. On the other hand, if the captured data exceeds the threshold data ri among the threshold data r1 to r1, the Cp IJ 131 extracts the corresponding alarm information P from the main memory 132 and sends it to the voice synthesis unit 136, and also sends it to the transceiver. The acquired data is given as a predetermined format to 102 and transmitted to the master station 200.

Thereby, the audio synthesis unit 136 synthesizes an audio signal corresponding to the alarm information Pi and sends the synthesized audio signal to the speaker 104. As a result, a corresponding announcement will be made from the speaker 104, and local residents will be notified.

On the other hand, the master station 200 has the same configuration as the slave station 100 (including an output device, etc.), receives the above data, prints it out, etc., and waits for the judgment of the monitor.

The monitor determines the necessity of warning from the output data,
100 necessary slave stations different from the slave station that sent the data (slave stations that are not generating an alarm) 40 necessary alarm generators
The necessary alarm information is sent to 0 via a wired line, and an alarm is generated. For example, as explained in Fig. 2, even if the data at the foal 1003 installed in the downstream area of the river 10 is below the threshold, if the data at the child station 1002 in the upstream area is above the threshold, the downstream Assuming that there is a possibility of river flooding in the area, warning information is sent to the slave station 1003 in the downstream area via a wired line to issue a warning.

[Effects of the Invention] As explained above, according to the present invention, the determination means provided in the slave station determines whether or not to issue a warning regarding the occurrence of a disaster, and if necessary, the warning means of the slave station issues an alert. Since the alarm is generated without waiting for alarm information from the master station, residents in the area where the slave station is installed can take appropriate measures.
