2. Description of the Related Art Conventionally, as an automatic notification system of this kind, for example, a transmitter is arranged at an upstream, a middle stream, or a downstream of a river, and a receiver is located at a place remote from the river and manages the river. The transmitter transmits data on the water level condition of the river, while the receiver receives the data, and based on the received data, the administrator can move to a place remote from the river. Depending on the water level, some people can take necessary measures even if they are present. FIG. 1 is a diagram showing an overall schematic configuration of the automatic notification system. In this figure, the state of the river water level detected by water level sensors installed at various places in the river is monitored by the monitoring panel 2 while the sensor input from the water level sensor is taken into the monitoring panel 2. . The transmitter 4 receives input from each sensor via the monitoring panel 2, converts the received sensor input into a form suitable for transmission as appropriate, and then performs remote dial transmission via the public line network 6 by automatic dial transmission. Receivers 101, 102, ..., 1 on the ground
At 0n, a notification is made that there is an abnormality in the water level of the river. Each of the receivers 101, 102,..., 10n automatically receives an incoming call, receives the transmitted data, and outputs the received data to an appropriate output device (not shown). Each output device outputs the data by hard copy or the like. However, in such an automatic notification system, when the water level of the river exceeds the warning level, the relevant parties are notified at the same time at the same time, so there is not enough time on the side receiving the notification, and the response is too late. There was a case.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an automatic notification system according to the present invention. The automatic notification system according to the present invention will be described by applying to an automatic notification system used for river water level management. The basic configuration is the same as that of FIG. Replace with description. Then, the respective configurations of the transmitter and the receiver in FIG. 1 are shown in FIGS. 2 and 3, and the configuration of the system of the present invention will be described with a focus on them. In the transmitter 4 shown in FIG. 2, 14 is an input unit, 16 is an output unit, 18 is a voice synthesis unit, 20 is a signal generation unit, 22 is a line interface, 24 is a signal reception unit, 26 is a calculation unit, 28 Is a clock unit, 30 is a memory, 32 is an interface, 34 is a determination unit, and 36 is a control unit.

A sensor input provided from a water level sensor, which is installed at various places in the river, for monitoring the water level via the monitoring panel 2 of FIG. It is provided from the input unit 14 to the determination unit 34. The determination unit 34 determines whether the water level is normal, caution level, caution level, or danger level based on the encoded sensor input, and determines the determination result among the telephone numbers stored in the memory 30. Is selected, a signal generator 20 generates an automatic dial signal, connects the line interface 22 to a receiver via the public line network 6, and selects one of the speech synthesis data stored in the memory 30. Then, speech synthesis data corresponding to the determination result is selected, and the speech synthesis unit 18 generates and transmits a predetermined speech based on the speech synthesis data. For example, the water level is normal,
In the case of the caution level, a message such as “the water level is normal” or “the water level is slightly increasing” and the actual water level data are sent to the corresponding river management office stored in the memory 30 by an automatic dial telephone. report. If the water level is at the alert level or at the danger level, the relevant river management office stored in the memory 30 and the department in charge of the prefectural office, or the like, "Water level has reached the alert level" or "Dike" And the actual water level data is reported by automatic dial telephone.

The transmission data includes not only the above-mentioned data stored in the memory 30 but also data necessary for management, such as the actual rise time or fall time of the water level and the installation location of the water level sensor. The data is calculated by the calculation unit 26 based on the detected data,
In addition to the data obtained by the timer 3, the memory 3 is controlled by the control unit 36 through the interface 32 as write data.
0 is stored. As shown in FIG. 4, a plurality of individual sensors, for example, at a predetermined position of a communication pipe higher than the height of the embankment via a pipe from a riverbed to a required position in a river basin,
Sensors A to E are provided, and the water level is detected for each sensor. In this case, when the water level rises or falls, the arithmetic unit 26 calculates the water level based on the output time difference between the adjacent sensors measured by the timer 28 and the distance between the corresponding sensors stored in the memory of the transmitter 4. The ascending or descending speed is calculated, and the calculated speed data is reported together with other data.

The receivers 101 to 10n shown in FIG.
It comprises a line interface 40, a signal generation unit 42, a signal reception unit 44, a memory 46, an input unit 48, a display unit 50, a signal processing unit 52, and a control unit 54. Line interface 40, signal generator 42, signal receiver 44, and memory 4
6 has the same functions as those of FIG. 2, and a detailed description thereof will be omitted. The input unit 48 is for inputting command data to the transmitter by a push button operation or the like from the receiver. The display unit 50 displays the data sent from the transmitter side and processed by the signal processing unit 52 and the command data.

The transmission operation of the transmitter 4 will be described with reference to the flowchart of FIG. After the initial setting of the transmitter 4 in step 1, it is determined in step 2 whether there is a data transmission request from the receivers 101 to 10n. When it is determined that there is the request, necessary data stored in the memory 30 is transmitted in step 10. If it is determined that there is no request, it is determined in step 3 whether or not there is an abnormal water level input from the sensor. If there is no such abnormal water level input, the process returns to step 2 above. If there is an abnormal water level input,
After determining the degree of abnormality in step 4 and storing the data of the determination result in the memory 30 in step 5, according to the determination result, the caution level processing is performed in step 6 and the notification destination is the corresponding river management office ( To A), water level data, water level rising speed data, sensor installation location data, time data, necessary voice messages and the like are transmitted. Step 7 is a case in which the result of the determination in step 5 is the alert level. In the process, the report destination is the relevant river management office (A) and the department in charge of the prefectural office (B), and the required data similar to that in step 6 is transmitted. I do.
Step 8 is a case where the determination result of step 5 is a danger level. The processing is carried out by the relevant river management office (A), the department in charge of the prefectural office (B) and the prefectural police headquarters (C). The same required data as described above is transmitted. In step 9, the transmitter 4 supplies a reset signal to each water level sensor via the output unit 16, and returns to before step 2.

Although not shown in the flowchart, when it is determined that the sensor installed in the transmitter 4 is abnormal (failure), it is immediately determined regardless of the transmission request on the receiving side. The sensor abnormality and the required data may be reported. In the above description, the output of each water level sensor is input to the input unit 14 of the transmitter 4 when the water level is detected. However, the output unit 16 of the transmitter 4 polls each water level sensor in a time-division manner. The state of the sensor may be detected. Further, in the above-described embodiment, the state of increasing water in the river is detected only by the plurality of water level sensors, and the relevant party is notified at each stage of danger, but for the same purpose,
A possible state may be predicted based on detection data from a plurality of types of sensors, and a forecast notification may be made according to the result. As an example, in addition to the detection data of the water level sensor, a database indicating the relationship between the basin rainfall and the river rise stored in the memory 30 in advance based on the detection data of a rain gauge installed at a predetermined location in the river basin. From
Forecast the future flood condition and give a notice.

[0012]

As described above, as an intermediate stage during which the water level of a river starts to increase and changes from a normal state to a dangerous state,
For example, the alert level, the alert level, the danger level, etc., are set in detail, and the report destination is selected appropriately for each level and the report is made. An automatic notification system is provided. Therefore, when the water level of the river exceeds the caution level, the fault of the conventional automatic notification system that notifies all relevant parties at once at that time has been improved. There is a merit that can be ensured sufficiently.
