Abstract

PROBLEM TO BE SOLVED: To suppress the generation of lack and lack in measurement of observation data so as to improve an acquisition rate of observation data. SOLUTION: If observation data is not received at a base station 2, automatic reading operation of the observation data which is not received is started by a telemeter device 15 until the next observation time. On the other hand, when a reread command is received by an antenna 4 and a radio device 5 at a buoy observation station 1, power of the telemeter device 6 is turned on at the buoy observation station 1 and a CPU 12 transmits normal observation data which is stored in a RAM 10 again to the base station 2 from the antenna 4 through the radio device 5.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sea condition including a buoy observation station installed on the sea and a base station installed on land in order to automatically observe the sea condition (sea condition) such as waves and wind speed. It relates to an observation buoy device.

[0002]

2. Description of the Related Art Conventionally, in the above-mentioned sea condition observation buoy device, various sensors mounted on the buoy observation station in response to an observation preheat command from the base station observe the sea condition and collect observation data. In response to the observation command, the buoy observation station transmits the observation data to the base station.

[0003]

However, in the conventional wave observing buoy device, since a radio line is used between the buoy observing station and the base station, the buoy oscillates extremely due to the influence of the wave, Alternatively, there has been a problem that the wireless line is momentarily disconnected due to the buoy being covered with waves, or the wireless line is extremely deteriorated due to the effect of fading, and the observation data is lost.

Therefore, the present invention provides a sea condition observation buoy device which solves the above-mentioned conventional problems, suppresses the occurrence of missing or missing observation data, and improves the acquisition rate of observation data. With the goal.

[0005]

To achieve the above object, the present invention provides a buoy observation station for observing the state of the sea and transmitting the observation data, and data obtained by receiving the observation data from the buoy observation station. In the sea condition observation buoy device consisting of a base station for processing, the buoy observation station, the wireless means, a sensor group for observing the sea condition, start the observation by an observation command from the base station at a predetermined time, and Telemeter means having a data storage means provided with data backup means for transmitting observation data to the wireless means and for transmitting observation data by the wireless means based on a rereading command from the base station after the observation is completed. And a radio means for transmitting to the base station an observation command or a rereading command to the buoy observation station via the radio means and receiving observation data. It is provided with a meter means and a data processing means for performing data processing based on the received observation data. According to this configuration, when the state of the wireless line is extremely deteriorated and data loss occurs, the observation is performed. Even after a certain period of time, if the data re-reading command is issued from the base station, the data from the buoy observation station will be backed up when the data stored in the data storage unit is in good condition. You can receive it, and you can complete the missing data.

[0006] By arranging the signal related to the observation command from the base station to be transmitted a plurality of times at intervals, the buoy observation station receives the signal in one transmission when the radio circuit condition deteriorates. Observation directives, even if not
By sending multiple times (including the observation preheat command), the observation start is surely performed.

By making it possible to add the data relating to the time or date and time to each of the observation data, it becomes easy to judge the missing data and the data can be complemented surely and accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system block diagram for explaining an embodiment of the present invention. Reference numeral 1 is a buoy observation station for observing waves and transmitting the observation data, and 2 is observation data from the buoy observation station 1. It is a base station that receives and processes data.

The buoy observation station 1 includes a group of various sensors 3 for observing the sea condition, a radio device 5 electrically connected to an antenna 4, a telemeter device 6, and a power supply device 7 for supplying power to each part. And the telemeter device 6
Transmits the observation data received from the sensor group 3 to the wireless device 5, and enables the wireless device 5 to transmit the observation data by the rereading command from the base station 2 even after the observation is completed. Therefore, I / O (Input / Output) control units 8 and 9 for controlling data input / output, and a RAM 10 with a data backup circuit as a data storage unit
And ROM11 and CP that controls each component
It consists of a U (central processing unit) 12.

On the other hand, the base station 2 sends a radio device 14 electrically connected to the antenna 13 and an observation command or a reread command to the buoy observation station 1 via the radio device 14, and In order to receive the observation data, a telemeter device 15 including a CPU (not shown) similar to the configuration of the telemeter device 6 and a data processing device 16 that performs data processing based on the received observation data are provided. I have it.

In the wave observation buoy device having the above-mentioned configuration, the preheat command for observation from the telemeter device 15 is transmitted from the antenna 13 in the base station 2 via the wireless device 14, and the preheat command is sent to the antenna 4 in the buoy observation station 1. And the wireless device 5, the power is turned on to the telemeter device 6 and the sensor group 3 on the buoy observation station 1 side, and the preheat command is sent to the CP via the I / O control unit 9.
It is input to U12 and ROM11 and the observation by the sensor group 3 is started via the I / O control unit 8. The observation data obtained by the sensor group 3 is sequentially stored in the RAM 10 and waits for a command from the base station 2 in this state.

On the other hand, the base station 2 sends an observation command to the buoy observation station 1 at the preset observation end time of the buoy observation station 1. In the buoy observation station 1, when the observation command is received, the CPU 12 reads the observation data stored from the RAM 10 and transmits it to the base station 2 by the wireless device 5 and the antenna 4. In the base station 2, the wireless device 14 and the telemeter device 15 receive the observation data via the antenna 13, and the data processing device 16 processes the data. After transmitting the observation data, the buoy observation station 1 turns off the power.

At this time, in the base station 2, if the observation data cannot be received, the telemeter device 15 starts the automatic reading operation of the observation data that cannot be received until the next observation time. This operation is repeated for 24 hours, increasing the probability that the wireless line status will be restored and data can be acquired. If the re-reading operation of the observation data can be manually set, the observation data can be obtained at any time.

Then, at the buoy observation station 1, the antenna 4
And when a reread command is received by the wireless device 5,
At the buoy observation station 1, the telemeter device 6 is turned on,
The CPU 12 transmits the normal observation data already stored in the RAM 10 from the antenna 4 to the base station 2 via the wireless device 5.
Send again to. The base station 2 obtains the necessary observation data, or after re-reading the necessary number of times,
A power-off command is sent to the buoy observation station 1.

When the wireless line condition is deteriorated, the observation command including the preheat command may not be transmitted from the base station 2 to the buoy observation station 1. Therefore, particularly, the preheat command is repeatedly transmitted a plurality of times. In addition, by transmitting again at an interval of about 1 minute, a more reliable observation command will be issued.

It should be noted that, when the observation data is sent from the buoy observation station 1, for example, when the observation data is transmitted from the buoy observation station 1, for example, when the observation data is missing for a long time or one day or more, it becomes unclear whether the observation data is missing. Telemeter device 6 of observation station 1
If the observation data is sent with identification data relating to the time, day of the week, etc., and the telemeter device 15 of the base station 2 or the like determines data loss based on the identification data, Completion can be done more accurately. The identification data may be added to the preheat command. It goes without saying that a plurality of buoy observation stations may be managed by the base station.

[0018]

As described above, according to the present invention,
When the condition of the wireless line is extremely deteriorated and there are many data loss or loss, if the data re-reading command is issued from the base station even after the end of the observation, the wireless line stored in the data storage unit where data is backed up It is possible to receive the data when the state is good, and it is possible to improve the data acquisition rate and supplement the missing data.

Further, even when the buoy observation station does not receive the data in one transmission when the wireless circuit condition is deteriorated, the observation command (including the observation preheat command) is transmitted a plurality of times to make an observation. The start will be surely performed.

Further, by adding the data relating to the time or date and time to the observation data, it becomes easy to judge the missing data and the data can be complemented surely and accurately.
