Description

A kind of novel sea iridium satellite GPS beacon machine

Technical field

The utility model is related to a kind of Radio Beacon, in particular, is to be related to a kind of novel sea iridium satellite GPS beacon machine.

Background technology

In marine environmental monitoring field, buoy, subsurface buoy, wave energy glider, underwater glider etc. are to obtain fixed point ocean The most common carrying platform of environmental monitoring data.It is used as a kind of continuous, long-term, unattended observation system, these oceans Enviromental monitoring equipment enjoys the favor of oceanographer and ocean engineering personnel all the time.Buoy, subsurface buoy, wave energy gliding The marine environmental monitoring such as device, underwater glider system be often laid on the length and breadth of land sea or certain depth under water, the system integration Many expensive measurements and detection instrument equipment, equipment also store substantial amounts of valuable data in measurement process, if During experiment or work, equipment or Missing data will cause huge economy and scientific research loss.Therefore how to realize The reliable recovery of system is one of the problem of must take into consideration before marine environmental monitoring system is laid.At present, based on hydrolocation skill The positioning of hyper-base line, Long baselines positioning and short baseline alignment system of art etc. are as main underwater position fixing technique, because system is multiple Miscellaneous, device therefor is expensive, lay recovery difficulty, so not turning into the main recovery side of marine environment monitoring device now Formula.The recovery of current subsurface buoy and underwater operation station, which is substantially all, employs GPS location data when system is delivered as recovery The mode of position, but marine environmental monitoring system is easily by various factors such as Marine Storm Genesis, the trawling of fishing boat, ocean currents Influence, system is likely to vary widely before recovery, so gives the search and recovery of marine environmental monitoring system Huge difficulty is brought, in some instances it may even be possible to cause the damage of equipment and the loss of data, so as to cause huge economic loss.By In the domestic Radio Beacon product for also lacking and being effectively used for searching, need to expend a large amount of manpower and materials and wealth before often equipment is laid Power carries out test of many times to improve recovery reliability, therefore it is extremely urgent to research and develop a effective ocean Radio Beacon product.

Radio Beacon is a kind of energy transmission of electromagnetic signals on target object (rocket, aircraft, ship etc.) and matched somebody with somebody with radar The electronic equipment of work, also referred to as answering machine or signal generator are closed, is usually that can launch the unidirectional of self geographical position information Sender unit.Because Radio Beacon can be indicated quickly and launch carrying current time, itself longitude and latitude, height above sea level etc. The signal of time geographical location information, therefore it is widely applied to rescue in danger and the auxiliary positioning of target search of Military and civil fields In.Ocean Radio Beacon is mainly laid on oceanographic equipment and instrument as one kind of Radio Beacon, and function is to be used to position in real time to work as Preceding equipment position, for the monitoring and recovery to equipment.

Currently, the method that ocean Radio Beacon completes to aid in the equipment such as submerged buoy system to reclaim typically has three kinds：One kind is beacon There is GPS location function and satellite communication function in machine system.After subsurface buoy emerges, Radio Beacon is started working, Radio Beacon Current positional information is obtained, then the positional information of acquisition is sent to by iridium satellite communication system and searches connecing on ship Receiving end, receiving terminal can determine the relative position of Radio Beacon and current ship according to the GPS position information of acquisition.This realization side Although method positioning precision is high but cost is also high, implement also cumbersome and protected from environmental than larger.It is another, letter Radio station's module of remote-wireless data transfer can be realized by having in mark machine system, and module is logical at interval of the regular hour The omnidirectional antenna crossed in Radio Beacon sends a number of data, and searches the user terminal on ship and receive this by alignment antenna A little information, directional aerial signal intensity when being directed at Radio Beacon is maximum, therefore can be using the signal intensity obtained, to judge letter The general orientation of mark machine.The cost of this method is than relatively low, and use is also more convenient, but positioning precision is not high, and searches Scope is limited by wireless module communication distance.Also a kind of, Radio Beacon can open the height in Radio Beacon after emerging Bright indicator lamp, indicator lamp flashes once at interval of certain time, so on the relatively good sea of field range, and the personnel of search can It is especially more convenient when using at night to be easily found very much submerged buoy system.The advantage of this method is it is obvious that using very Simply, it is only necessary to which a Radio Beacon, without ustomer premises access equipment, cost is very low.Shortcoming is similarly obvious, is used on daytime When, it is not easy to find, and such equipment is used apart from shorter, is influenceed also than larger by weather.
