The measurement floating body and its operation management system use a marine environment measurement system. Note that the measurement target in this marine environment measurement system is not particularly limited, but is various states such as marine conditions, weather, temperature, pressure, and speed in the sea.
[0011]
By the way, as shown in FIG. 1, the marine environment measurement system includes a measurement device 1 that floats on a predetermined sea surface and measures a marine environment in the sea area, and measurement data obtained by the measurement device 1. And a base station 2 for monitoring the marine environment. The exchange of data and control signals between the base station 2 and the measuring device 1 uses radio waves such as ground waves. The communication is performed by wireless communication and / or satellite communication using radio waves from artificial satellites.
[0012]
As shown in FIG. 2, the base station 2 includes a computer device 12 connected to an uninterruptible power supply device 11 and a wireless communication device (composed of a transmitter and a receiver) 13 connected to the computer device 12. And a digital communication device 14 for performing data communication using a digital communication line with an earth station (or management station) of a satellite communication line using a low orbit satellite.
[0013]
As shown in FIG. 3, the measuring device 1 includes a buoy having various sensors 23 that are moored to a mooring member 21 such as an anchor disposed on the sea floor and float on the sea surface to detect a marine environment. A (buoy for measurement) 22 and an arithmetic and control unit (computer device) 24 provided on the buoy 22 for accumulating measurement data from various sensors 23 and managing the operation of various components are also provided. A wireless communication device (comprising a transmitter 25a and a receiver 25b) 25 provided on the buoy 22 for performing wireless communication with the base station 2 and a satellite communication provided on the buoy 22 for performing satellite communication Device (consisting of a transmitter and a receiver) 26, and disposed between these two communication devices 25, 26 and the arithmetic and control unit 24 so that one of the communication devices can be used. A communication switch 27 for selectively switching power; a power supply (battery) 28 for supplying power to each component requiring power such as the arithmetic and control unit 24; A power distribution controller 29 provided between the power supply controller 29 for supplying and stopping power to each of the constituent devices, and a solar cell for supplying electricity to the power supply device 28 via a charge controller 30 for preventing overcharging and the like.

Of course, the communication switch 27, the power supply 28, the power distribution controller 29, the charge controller 30, the solar cell panel 31, and the wind power generator 32 are provided on the buoy 22, and although not shown, each of these In addition to the components, a marker lamp and the like are provided. Note that a wave power generator can be used instead of the wind power generator 32.
[0014]
Next, a configuration corresponding to the operation management system of the present invention will be described.
The operation management system includes an operation control unit 24a in the arithmetic and control unit 24, and power supplies from a wireless communication device 25, a satellite communication device 26, a wireless switch 27, and a power supply device 28. And a power distribution controller 29 for supplying and stopping power.
[0015]
The operation control unit 24a has a time schedule for operating various components required for measurement and measurement data transmission of the various sensors 23, the wireless communication device 25, the satellite communication device 26, and the like at predetermined time intervals. Have been.
[0016]
The time schedule includes, for example, a standard measurement mode for intermittently measuring the marine environment and a continuous measurement mode for continuous measurement. In the standard measurement mode, for example, measurement is performed for 10 minutes and then for 20 minutes. In the continuous measurement mode, the measurement is naturally performed continuously.
[0017]
Further, the operation management system has a function of changing the time schedule of each component device based on a command (control or command signal) from the base station 2. Specifically, the change function (change program) is incorporated in the operation control unit 24a, and in order to respond to a command from the base station 2, for example, the receiver 25b of the wireless communication device 25 is set to be in a 10-minute interval. The power supply is controlled by the power distribution controller 29 so as to operate for 5 minutes. That is, the power distribution controller 29 includes a timer (timed switch) 29a for executing a time schedule. The operation control unit 24a and the power distribution controller 29 of the arithmetic and control unit 24 constitute a power management unit.
[0018]
Next, an operation of the operation management system will be described.
When the water temperature is measured by various sensors 23 provided on the buoy 22, for example, a water temperature meter as the marine environment, power is supplied to predetermined components by a timer 29 a provided in the power distribution controller 29, and the measurement is performed. Is
[0019]
When the standard measurement mode of the time schedule shown in FIG. 4 is set, the water temperature is detected for 10 minutes, and the water temperature data detected during the 10 minutes is stored in the data storage unit 41.
[0020]
The water temperature data is sent to the base station 2 via the wireless communication device 25 according to the time schedule. Although the transmission schedule of the water temperature data, that is, the measurement data, is not shown in FIG. 4, for example, several minutes after the detection of the water temperature data, transmission is performed by increasing the transmission efficiency by data compression or the like.
[0021]
When the measurement mode is changed, the measurement mode is changed by transmitting a switching command from the base station 2 in accordance with the command waiting time on the buoy 22 side.
Further, the content of the time schedule, that is, the measurement time and the measurement interval can be freely changed by a command from the base station 2.
[0022]
Further, the buoy 22 is provided with a solar panel 31 and a wind power generator 32, and electric power generated according to weather conditions is supplied to the power supply device 28 via the charge controller 30 to perform charging. ing.
[0023]
After an operation or the like by a command from the base station 2 is performed, for example, the power is automatically turned off. Of course, even when an operation by a command or the like is performed, the power can be kept on for a certain period of time.
[0024]
Further, the arithmetic and control unit 24 may have the following functions.
That is, the power supply voltage measuring means may be connected to the output terminal of the power supply device 28, and the measurement result may be taken into the arithmetic and control unit 24. In this case, it is recognized that the limit state is near by reaching a predetermined voltage, for example, a voltage at which the operation becomes unstable, so that the highest priority function as a floating body in the case of at sea, for example, a light can be maintained. Power supply to other power consuming devices can be stopped. However, this is a case where a power supply dedicated to the lamp is not provided. In addition, by transmitting the measurement result of the voltage of the power supply device 28 to the base station 2, the base station 2 can also perform power management. Alternatively, a plurality of predetermined voltages may be determined as the alert levels, and a device for stopping the supply of power may be determined for each level, so that the life of the power supply device 28 may be extended.
[0025]
In addition, a time limiter for continuous measurement may be provided so as to cope with a mistake in creating a schedule or the like, forcibly terminating the measurement when continuous measurement is performed for a predetermined time. After the completion of the measurement, basically, a command waiting state from the base station 2 is kept, and when the power supply device 28 is in the limit state, the power supply to the wireless communication device 25 is temporarily stopped. Alternatively, the power generation unit connected to the power supply device 28 may return to the command reception waiting state after the power supply voltage is recovered. When the measurement data up to that time is transmitted to the base station 2 after the forced measurement due to the measurement time limit, a message indicating the forced termination due to the time limitation may be transmitted. The base station 2 can recognize that the forced measurement has been completed when the above message is received or when information from the floating body such as measurement data cannot be received as scheduled.
[0026]
As described above, the power supply is turned on / off in accordance with (according to) a predetermined time schedule for the measurement operation of the marine environment and the transmission operation of the measurement data to the base station 2. , The power consumption of the power supply device can be reduced, which leads to a reduction in manufacturing cost.
[0027]
More specifically, since the time schedule for measurement and the like can be changed from the base station, for example, when a water thermometer is provided, the power supply is usually set such that the continuous measurement time is 5 minutes and the suspension time is 1 hour. If you want to continuously monitor the rise in water temperature, for example, when an undersea volcano explodes nearby while performing intermittent measurement while saving time, make the ratio of the continuous measurement time from the base station longer than the pause time. By transmitting the set time schedule, an emergency situation can be flexibly dealt with. Also, when equipped with sensors capable of measuring waves and when investigating the effects of large earthquakes in remote areas such as the Southern Hemisphere and the Americas, the time for continuous measurement is the same as when measuring water temperature. By increasing the ratio or setting the pause time to zero, measurement can be performed at appropriate intervals while suppressing power consumption, and data can be continuously collected as needed when necessary.
[0028]
By the way, in the above-described embodiment, the timer 29a is provided on the power distribution controller 29 side, but may be provided on the operation control unit 24a side, for example.
[0029]
【The invention's effect】
As described above, according to the configuration of the measurement floating body and the operation management system of the present invention, the power supply means for automatically turning on and off the power supplied to at least the measurement equipment is provided, for example, according to a time schedule. Therefore, power consumption of at least the measuring device can be reduced, and the capacity of the power supply device can be reduced, which leads to a reduction in manufacturing cost.
