Abstract

The present invention relates to a calling type electric buoy which at least comprises a host board, a GPS receiving module which is connected with the host board, a single-chip microprocessor, a main receiver, a decoder and a frequency shift key transmitter. The information data (such as a clock, latitude and longitude, water temperature, flow speed, etc.) which is received by the GPS receiving module is compressed and preserved by the single-chip microprocessor, and after a calling signal is received by the main receiver in waiting receivers, the calling signal is decoded by the decoder; after the signal is correctly compared, the information data which is stored by the single-chip microprocessor is sent out by the frequency shift key transmitter. Thus, after the calling signal is decoded and compared correctly, the information data in the single-chip microprocessor of the electric buoy is sent out, which can improve the functions of electricity saving, high safety, no interference, etc.

Description

Calling electric buoy

Technical field

The invention relates to a kind of improved calling electric buoy, GPS location, collection information are closed in outstanding assignment, reach the calling electric buoy that call signal is just breathed out after the decoding comparison is correct.

Background technology

Exhalation machine and receiver are a kind of communication apparatus of unidirectional conduction message, this electric buoy 10 that can use such as navigation and aboard ship receiver 20 (as Fig. 1), traditional navigation has timer with electric buoy 10 inside, fixing control at interval by setting-up time transmits, receiver 20 received signals that orientation detection is aboard ship used, and then differentiate the title and the direction of each electric buoy 10, and because the factor in the time interval, personnel must keep receiver 20 other keeping and listen, again because of grasping the time that each electric buoy 10 will be sent back to, and because the free again error of the timer of each electric buoy 10, the interference that produces signal so launch simultaneously sometimes, and electric buoy 10 at sea can't powered-down, the twenty four hours emission, therefore, very power consumption and must change battery often, business efficiency is relatively poor, in addition, the state of electric buoy 10 because of keeping transmitting is so its position is learnt by other fishing boat easily, make confidentiality poor, fishery harvesting is often arranged, the stolen thing of fishing gear takes place.

Summary of the invention

Therefore, this case inventor is because the above-mentioned person's of commonly using present situation, satisfy and think to reach if can utilize the group number that makes each electric buoy, password is through setting signal for, exhalation machine is not breathed out at ordinary times, electric buoy is not promptly launched, the power saving of not repaying is set, can overcome the aforementioned person's of commonly using disappearance, therefore, satisfy and think again and concrete technology composition, can make calling electric buoy, it comprises the GPS receiver module of motherboard and connection thereof, the single-chip microprocessor, main receiver, decoder, shift frequency key emitter, and the GPS receiver module is can be with information material (as clock, longitude and latitude, water temperature, flow velocity etc.) preserve by the compression of single-chip microprocessor, and the main receiver that only keeps holding state is at ordinary times deciphered via decoder after obtaining call signal, the information material that the single-chip microprocessor is stored.Launch via shift frequency key emitter, make to reach and promote power saving, confidentiality height, noiseless etc. function.

Therefore, main purpose of the present invention makes the calling electric buoy can be at the signal of obtaining group number, password, and after the decoding comparison is correct, the information material that the single-chip microprocessor is stored is launched, and main receiver only keeps special machine state at ordinary times, exhalation machine is not breathed out, and electric buoy is not promptly launched, do not compared, and reaches power saving, confidentiality height, glitch-free superiority target.

Embodiment

Modern for making your auditor to the present invention further understanding be arranged, Zi Zuo is illustrated with following specific embodiment.

See also shown in Figure 2ly, calling electric buoy of the present invention includes motherboard 1 at least, and the GPS receiver module 2, single-chip microprocessor 3, main receiver 4, decoder 5, the shift frequency key emitter 6 that connect, wherein:

Motherboard 1 (circuit diagram such as Fig. 3), it has mu balanced circuit 11 and is provided with battery component 12, and be provided with total power switch 13, can be provided with power supply dial gauge 14 in addition, total power switch 13 can be provided with ON, the option of TEST and OFF (as Fig. 2), wherein cut in the ban to TEST, enter the power supply test pattern, can start shift frequency key emitter 6 during power supply test, the consumed power of full machine when power supply dial gauge 14 is then launched in order to measurement, indication does not reach the specific region as pointer, then represents the electric weight deficiency and necessary replacing battery, and pointer indication is if reach the specific region, then can cut to the position of ON to start start.

GPS receiver module 2, it is connected to single-chip microprocessor 3, and be provided with gps antenna 21, and reach relevant walrus data (as clock, longitude and latitude, cell voltage, water temperature, flow velocity etc.), and the information material of receiving is stored in single-chip microprocessor 3 (as Fig. 2, Fig. 4, Fig. 5) in order to the ephemeris data that the reception satellite reaches.
