Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a tide level transmission method using numerical data that automatically measures the tide level and transmits it as numerical data.

(Prior Art) Conventionally, tide levels have been measured by visually reading tide level plates using field tools.

(Problems to be Solved by the Invention) However, the method of visually reading the tide level has a problem in that the reading values vary due to individual differences. In addition, since tide level boards are usually installed on quay walls, there is a risk that field equipment may be washed away by waves at night. Furthermore, the sea surface is constantly shaking due to the influence of waves, so the readings are not constant, leading to errors in readings and a time-consuming problem. Due to construction accuracy, it is necessary to measure the tide level at intervals of, for example, 10 to 15 minutes, and there is a problem in that two to three people are required to be on site during the day and night.

On the other hand, it is also possible to wirelessly transmit the tide level using radio waves, but in this case, there are regulations under the Radio Law, and notification to the relevant government agencies and qualifications are required, and there is a problem that only qualified persons can use it. . Furthermore, it is necessary to install a transmitter and a receiver on the transmitting side and the receiving side, respectively, which poses a problem of high cost.

An object of the present invention is to provide a method and device for transmitting tidal levels using numerical data that can automatically measure tidal levels and transmit them by radio waves without the need for notification or qualifications to relevant government agencies.

The tide level transmission method using numerical data of the present invention automatically measures the tide level with a water level sensor, calculates the optimal value of the obtained tide level signal with a computer, converts it into an audio signal, and sends it to a transmission center via a telephone line. The transmission center converts the audio signal into tidal level numerical data and wirelessly transmits the data using radio waves.

The tide level transmission device using numerical data of the present invention includes a water level sensor that detects sea level height, and calculates an appropriate R value of the tide level signal output from the water level sensor and automatically sends a transmission signal at each set time interval. a computer that outputs a dialing signal for the other party; a converting unit that converts the optimal tide level signal calculated by the computer into an audio signal; a telephone line that transmits the audio signal output from the converting unit; and transmission over the telephone line. and a transmission center that converts the voice signals into tide level numerical data and wirelessly transmits the data using radio waves.

(Operation) Measuring the tide level with a water level sensor eliminates the need for on-site staff and can be measured without reading errors.

By converting the tide level signal into an audio signal and sending it via telephone line, it can be sent to a transmission center without the need for notification or qualifications to the relevant government agencies.
