Abstract

PURPOSE: To more suitably and reliably alarm over bank wave by calculating current data for over bank wave decision while using the measured data of plural sensors for measurement, and comparing the calculated data for tidal wave decision with threshold data in a storage means. CONSTITUTION: A measured data transmitting means 11 converts signals from the respective sensors for waveheight, wind velocity, wind direction, tide level and rainfall to digital data, synthesizes those data into serial data and transfers them to a decision control means 14. The decision control means 14 converts the data transferred from the measured data transmitting means 11 to data (z) for over bank wave decision to evaluate whether it gets over the bank or not. First of all, the decision control means 14 calculates current data zo for over bank wave decision and compares them with threshold data (z) in a storage means 13. In the case of zo>z, an over bank wave alarm signal is outputted to an alarm control means 17. In the case of zo<z, predicted data zt for over bank wave decision after the lapse of time T are compared with the threshold data (z). In the case of zt>z, an over bank wave predictive alarm signal is outputted to the alarmans 17.

[0024]

1 is a diagram showing the configuration of an overtopping prediction system of the present invention. Each sensor for wave height, wind speed, wind direction, tide level, and rainfall is connected to the measurement data sending means 11. Further, the measurement data sending means 11 is connected to a logging processing means 15 for accumulating measurement data from each sensor.
A data output means 16 for outputting the accumulated data is connected to the logging processing means 15. The measurement data sending means 11 is connected to the determination control means 14 by wire or wirelessly. The storage unit 13 is connected to the determination control unit 14. The storage unit 13 stores threshold value data for determining whether or not to carry out overwave notification or overwave prediction notification. The data input means 12 is connected to the judgment control means 14. The determination control means 14 is connected to the notification control means 17 by wire or wirelessly. An overtopping notification unit 18 and an overtopping prediction notification unit 19 are connected to the notification control unit 17.

The measurement data sending means 11 is for measuring the wave height, wind speed,
The signals from the wind direction, tide level, and rainfall sensors are converted into digital data such as wave height data u, wind speed data v, wind direction data w, tide level data x, and rainfall data y. Then, these data are combined into one serial data and transferred to the judgment control means 14. The signals from the respective sensors converted into digital data by the measurement data sending means 11 are accumulated in the logging processing means 15. The accumulated data can be output from the data output means 16. Storage means 13
Stores threshold data and the like for determining whether or not to perform overwave notification or overwave prediction notification as a database file, and the threshold data and the like are input from the data input means 12. The judgment control means 14 converts the wave height data u, wind speed data v, wind direction data w, tide level data x, and rainfall amount data y from the measurement data sending means 11 into overtopping judgment data z for evaluating whether or not the wave should be overwhelmed. To do. In this conversion, the influence of each measurement data on the overtopping wave is checked by a preliminary investigation, the relation is mathematically expressed, and incorporated in the data processing program of the determination control means 14. Then, the determination control means 14 compares the converted overtopping determination data z with the threshold data Z in the storage means 13. The threshold data Z is the value of the overtopping determination data z when the overtopping actually occurs, and is determined by a preliminary investigation. The determination control means 14 first determines the current overtopping determination data z.
₀ is calculated and compared with the threshold data Z. As a result, when the current overwave determination data z ₀ is larger than the threshold data Z, the determination control means 14 outputs an overwave notification signal to the notification control means 17. If it is small, overtopping prediction is performed,
The overtopping determination data z _T after the predicted T time is compared with the threshold data Z. T is the time required from the time the overtopping prediction is notified until the safety of the road adjacent to the breakwater is ensured, and is input by the maintenance person from the data input means 12. As a result, when the overtopping determination data z _T after the time _T is larger than the threshold value data Z, the determination control unit 14 outputs the overtopping prediction notification signal to the notification control unit 17. The alert control means 17 is an overwave alert means 18 if it is an overwave alert signal.
If the signal is an overwave prediction notification signal, the overwave prediction notification means 19 is activated.

In the configuration of FIG. 1, the measurement data sending means 11
And the determination control means 14 and between the determination control means 14 and the notification control means 17 are serialized, and data is transferred by radio or coaxial cable, optical fiber or the like.
For this reason, the measurement data sending means 11, the logging processing means 15, and the data output means 16 can be installed together with the sensors in a dangerous place, and the judgment control means 14 and the storage means 1 can be installed.
3 and the data input means 12 can be installed in a safe place where the maintenance person is, and the notification control means 17, the overtopping wave notification means 18, and the overtopping prediction notification means 19 can be installed in the place where the person who should actually give the alarm is.

The control unit 20, the storage unit 21, the overtopping data operation unit 22, the overtopping data prediction operation unit 23, the determination unit 24, the input control unit 25, and the output control unit 26 are connected via an internal bus. The control unit 20 controls the operation procedure of each unit. The storage unit 21 stores the measurement data of each sensor transferred from the measurement data sending unit 11 a predetermined number of times. When new measurement data arrives while the storage unit 21 stores the measurement data a predetermined number of times, the oldest measurement data is discarded and the new measurement data is stored. The overtopping data calculation unit 22 obtains the current overtopping determination data z ₀ , and the overtopping data prediction computation unit 23 obtains the overtopping determination data z _T after the predicted T time. The determination unit 24 reads the threshold data Z of the overwave notification or the overwave prediction notification from the storage unit 13, and the current overwave determination data z ₀ obtained by the overwave data operation unit 22 or the overwave data prediction operation unit 23 is obtained. Data _T for overtopping determination after T time
And threshold data Z are compared and determined. As a result, if the current overwave determination data z ₀ exceeds the threshold data Z, an overwave alert signal is output to the alert control means 17, and the overwave determination data z _T after T time is the threshold data Z. If it exceeds, the overwave prediction notification signal is output to the notification control means 17.

The overtopping data calculation unit 22 uses the prepared formula z = f (u, v, w, x, y) to calculate the current wave height data u ₀ , wind speed data v ₀ , wind direction data w ₀ , tide level data. Substituting x ₀ and the rainfall data y ₀ , the current overtopping determination data z ₀ is obtained. As a result, even if the measurement data of one sensor has noise or a temporary change in the measurement value, the influence can be reduced, and the reliability of the overtopping determination can be improved.

(S62) ... The measurement data sending means 11 A / D-converts the collected signal to obtain measurement data. (S63) The measurement data sending means 11 converts the measurement data into serial data and transfers it to the judgment control means 14. In this serial data, wave height data, wind speed data, wind direction data, tide level data, and rainfall data of predetermined bits are arranged in a predetermined order. (S
64) The logging processing means 15 stores the measurement data of each sensor in the order of the measured time together with the measured time. (S
65) The data output means 16 prints out the measurement data according to an output instruction of a maintenance person from a key input device (not shown) or the like. The printed data is, for example, a list of measurement data and measurement time for each sensor, and the threshold value Z or the calculation formula z = f (u,
v, w, x, y) can be used for evaluation as to whether or not they are appropriate.

The input data input from the data input means 12 is processed by the program corresponding to the flowchart of FIG. 7, which will be described. (S71) The data input means 12 is composed of, for example, a keyboard input device, etc., and the maintenance person uses the threshold data Z and the overtopping wave prediction time T.
Enter. (S72) The judgment control means 14 fetches the inputted threshold value data Z and the overtopping wave prediction time T and stores them in a predetermined area of the database file of the storage means 13 so that they can be read out later. The storage unit 13 is composed of, for example, a hard disk device or the like.

Each part of the judgment control means 14 is composed of a microcomputer or the like and operates by a program corresponding to the flowchart of FIG. 8, which will be described.
(S81) The input control unit 25 uses the measurement data sending means 11
Monitor whether measurement data is sent from. (S8
2) When the measurement data is sent, the input control unit 25 performs serial / parallel conversion to obtain wave height data, wind speed data, wind direction data, tide level data, and rainfall data of each predetermined bit, and stores it in the storage unit 21 in FIG. Store as shown. (S8
3) Upon receiving the notification of the arrival of the measurement data from the input control unit 25, the control unit 20 transfers the latest measurement data from the storage unit 21 to the overwave data calculation unit 22. Therefore, as shown in FIG. 3, the current wave height data u ₀ , wind speed data v ₀ , and wind direction data w are stored in the register 32 of the overtopping wave data calculation unit 22.
₀ , tide level data x ₀ , and rainfall amount y ₀ are stored. (S84) The overtopping wave data calculation unit 22 calculates z = f.
By substituting each value of the register 32 into (u, v, w, x, y), the current overwave determination data z ₀ is obtained and transferred to the determination unit 24. (S85) The control unit 20 reads the threshold value data Z from the storage unit 13 and transfers it to the determination unit 24. (S86) The determination unit 24 makes a comparison determination as to whether or not the current overtopping determination data z ₀ exceeds the threshold value data Z, and passes the result to the control unit 20. If it exceeds, the process proceeds to step S89, and if not, the process proceeds to step S87. (S87)
If the current overwave determination data z ₀ does not exceed the threshold data Z, the control unit 20 activates the overwave data prediction calculation unit 23, and the overwave data prediction calculation unit 23 causes the overwave determination data after T time. z _T is obtained and transferred to the determination unit 24. (S88) ... The determination unit 24 determines whether or not the overtopping determination data z _T after T time exceeds the threshold value data Z, and passes the result to the control unit 20. If it exceeds, the process proceeds to step S8A, and if it does not exceed, the process returns to step S81 and the control unit 20 operates so as to repeat the processes up to step S88. (S89) When the current overwave determination data z ₀ exceeds the threshold data Z, the control unit 20 outputs the overwave notification signal from the output control unit 26. (S8A) ...

By performing the overtopping prediction as described above,
It becomes possible to perform highly reliable overtopping prediction notification. FIG. 5 is a graph showing the relationship between the overtopping determination data z and the time t. In the state of this graph, since the current overwave determination data z ₀ does not exceed the threshold value Z at the current time t ₀ , the overcurrent is not notified, but the overwave determination data z _T after T time is the threshold value data. Since it exceeds Z, it indicates that the overwave prediction is to be notified.

In the above embodiment, the threshold data Z
Was determined by a preliminary survey. In another embodiment, the threshold data Z is updated using the current overwave determination data z ₀ as needed while monitoring the situation in which an overwave actually occurs. That is, when the overwave notification is not issued despite the occurrence of the overwave, the maintenance person uses the data input means 12 to the storage means 13 so that the current overwave determination data z ₀ is set as the new threshold data Z. Update the content. Alternatively, when operating the system unattended, a sensor for detecting that a wave has crossed the breakwater is used, and when the determination control means 14 receives a signal indicating that the wave has been detected from this sensor, the determination control means 14 stores it in the storage means 13. The judgment control means 14 has a function of automatically updating the threshold data Z. As a result, it is possible to build a system that can flexibly respond to changes in the situation.
