Will by armored concrete gravity type anchor, flexible anchor chain and tethers ring group into.
The defect that the present invention exists for Big Dipper ocean monitoring buoy in prior art, proposes solution below：
(1), the low solution of Big Dipper buoy information launching success rate
Big Dipper buoy is typically point at a fixed time, and the various state parameters and various kinds of sensors of Big Dipper buoy are adopted
The information of collection is transmitted by Big Dipper RDSS terminals, but due to the influence of fluctuations of wave, in set time point letter is transmitted
Number when, Big Dipper RDSS terminal antennas by chance in roll and pitch position, thus resulting in Big Dipper signal cannot broadcast TV programs by satellite, message
Lose.The transmitting flow process of current Big Dipper buoy RDSS terminals is as shown in Figure 3.
For the above-mentioned problem for causing Big Dipper RDSS terminal transmission success rates low, multi-section Big Dipper RDSS terminal antennas are pressed
Bundled according to the form of inverted cone, such as Fig. 4 bundlees schematic diagram for a kind of easy Big Dipper RDSS terminal antennas inverted cone, needs
, it is noted that Fig. 4 be only merely it is a kind of simple illustrate, actual Big Dipper RDSS terminal antennas can increase according to monitoring needs and add deduct
It is few.
Real work flow process：The information that buoy is gathered is stored in subscriber computer caching in the form of message, then user
Machine carries out detection judgement to multi-section Big Dipper RDSS terminal signalings power condition, is less than when current RDSS terminal powers situation is determined
During the index request for succeeding in sending up, do not launch, detection judgement is carried out to next Big Dipper RDSS terminal signalings power condition, once
When monitoring that power satisfaction is required, launched at once, thus can be very good to solve Big Dipper RDSS terminal transmission success rates
Low problem, and user if it find that certain subscriber computer is not successfully delivered newspaper, text comes, the Big Dipper can be excited with manual-remote
RDSS terminals are transmitted again.This mode can reach more than 98% through practice test, success rate, can meet user
Demand, workflow diagram is as shown in Figure 5.
(2), Big Dipper buoy information transmitting frequency is low and single sends the limited solution of byte
Art is taught skill using Big Dipper cluster number and improves Big Dipper RDSS short messages transmission frequency, sent Big Dipper SIM is not being changed
On the premise of frequency and single send information content, by multiple raisings that send in turn for blocking frequency and information transfer speed are sent
Rate.
First, Big Dipper transmission quantity is improved.The information content of common Beidou subscriber machine short message function transmission, it is impossible to meet sea
The transmission demand of foreign buoy monitoring information, is needed the technology passed using cluster number to improve and sends frequency and transmission quantity.Secondly, system
Fixed general standardized communication protocols.Data exchange, the packing transmission of information and compatible other number arq modes are realized, is realized seamless
Connection, it is necessary to encode to signal, sets up the Beidou communication standardization agreement of oceanographic buoy monitoring information, function composition structure
Block diagram is as shown in Figure 6.
Main thought：First, the real-time reception data to be transmitted, store to receiving data, then carry out at data
Reason, data processing mainly includes that data cleansing and data integrity are compared, then gives the individual Big Dipper RDSS modules of n (n >=1), by when
Sequence control module controls n Big Dipper RDSS module and in turn switches at a time interval, and data is activation is gone out, thus can be with
Realize that Big Dipper short message sends the control of frequency.For example, if it is desired to realizing sending a secondary data every 30 seconds, it is possible to use 2
Individual Big Dipper RDSS modules, it is assumed that first RDSS sends at the T0 moment, then second RDSS sends at T0+30 moment second.If
Want to realize transmitting a secondary data every 20 seconds, it is possible to using 3 Big Dipper RDSS modules, it is assumed that first RDSS sends out at the T0 moment
Send, second RDSS sends at T0+20 moment second, the 3rd RDSS sends at T0+40 moment second, and the rest may be inferred, in theory may be used
To realize arbitrarily sending frequency.
Three kinds of situations of the main thought of SECO point：
(1) the first situation, data volume is normal
According to the instruction of time-sequence control module, RDSS modules are in turn switched at a time interval with rule, and data are sent out
See off.It is assumed that needing interval to send a secondary data in x second, then the RDSS module numbers at most needing and SECO thinking are such as
Under：
1) when 60/x can divide exactly
When 60/x can divide exactly, 60/x RDSS module is needed.During concrete transmission information, time-sequence control module is according to solid
Fixed interval in turn switches on RDSS modules, first RDSS module is connected first, then second RDSS module, until connecting the
First RDSS module is connected in 60/x RDSS module, then recycling, and other RDSS modules are connected in circulation successively.For example, need
When being spaced 10 seconds one secondary datas of transmission, then 60/10=6 RDSS module, time-sequence control module is needed in turn switch on 1-6
Individual RDSS modules, then later connect again first RDSS, move in circles.
First RDSS module：0th second；
Second RDSS module：10th second；
3rd RDSS module：20th second；
4th RDSS module：30th second；
5th RDSS module：40th second；
6th RDSS module：50th second；
First RDSS module：1st minute.
2) when 60/x can not divide exactly
When 60/x can not divide exactly ,+1 RDSS module of 60/x (taking business) is needed.During concrete transmission information, SECO
Module in turn switches on RDSS modules according to fixed intervals, first RDSS module is connected first, then second RDSS module, directly
To 60/x (taking business)+1 RDSS module is connected, first RDSS module is connected in then recycling, and RDSS is connected in circulation successively
Module.
For example, it is desired to when being spaced 8 seconds one secondary datas of transmission, then need 60/8 (taking business) Jia 1 again, i.e., 8 RDSS modules,
Time-sequence control module in turn switches on the 1-8 RDSS module, and sequential is allocated as follows：
First RDSS module：0th second；
Second RDSS module：8th second；
3rd RDSS module：16th second；
4th RDSS module：24th second；
5th RDSS module：32nd second；
6th RDSS module：40th second；
7th RDSS module：48th second；
8th RDSS module：56th second；
First RDSS module：1st point 4 seconds.
That is, after first RDSS module sends for the first time, having crossed 1 point and having sent within 4 seconds second, the rest may be inferred for other
Analogize.
(2) second situation, data volume is bigger than normal
When data volume is bigger than normal, in order to alleviate the burden of RDSS modules transmitting-receiving, can be first right with data memory module
Data are cached, and then according to the control signal of time-sequence control module, using the algorithm flow in the case of the first, are connect successively
Logical RDSS modules carry out the transmission of data.
(3) the third situation, data volume is zero
When data volume is zero, for the valuable communication channel resources of energy saving and saving, according to SECO
The control signal of module, closes the transmitting-receiving of RDSS modules.
