Specific embodiment
Illustrate below and the present invention is described in more detail.
The real-time Transmission drive marine parameter buoyage of the present invention mainly includes temperature depth measuring instrument TD, thermohaline depth measuring instrument
CTD, acoustic Doppler fluid velocity profile instrument ADCP, ADCP battery compartment, inductively ADCP data converting circuits, data transmitter
SSM, inductively data acquisition unit HEM, inductively data receiver ring CCA, inductively temperature and pressure measuring cable, buoy standard type,
Buoy main control unit, FGR2 radio stations, FGR2 radio antennas, 13V lithium battery groups, acoustic releaser and anchor block.
Fig. 1 gives the annexation between real-time Transmission drive marine parameter buoyage each several part, wherein：1 is logical
Letter buoy, 2 be shackle, 3 be ADCP and its battery compartment, 4 be ball float, 5 be change, 6 be acoustic releaser, 7 be lifting suspension ring, 8
It is wirerope, 9 is sinker.System adopts Vertical Anchor architecture, buoy lower end to hang coupled transfer cable, can be on demand on coupled transfer cable
Ask with arbitrary interval, quantity placement TD1-16, CTD1-4.Coupled transfer cable lower end hangs ADCP and ADCP batteries by shackle
Storehouse, ADCP data converting circuits are connected by watertight feeder line with the SSM of coupled transfer cable bottom, and ADCP lower ends are ball floats, are led to
Ball float counterweight is crossed, buoyage can be made in vertical state, and communicating buoy half is bubbled through the water column, the change of ball float lower end can be with
Coupled transfer cable is avoided to be subject to excessive radial rotary active force.
Fig. 2 gives data transfer flow process figure.Communicating buoy includes electricity as data transfer, the carrier of control, its structure
Source, anchor lantern, radio antenna, inside includes HEM, governor circuit, radio station module.TD, CTD, ADCP are according to required sample rate and number
According to form simultaneously gathered data, wherein ADCP data are first transmitted in data converting circuit, store after de-redundancy to
RAM.Each 10min data of TD, CTD, ADCP are used as a disposed of in its entirety.Buoy governor circuit is every by coupling transmission system
Successively a upper 10min data are asked for each TD, CTD, ADCP every 10min, and stored to SD card.Bank station passes through FGR2 radio station
Data are asked for buoy every 10min in principal and subordinate's broadcast communication mode, the real-time upload of data is realized.
Fig. 3 gives SD card initialization flowchart.SD is used to store the data of TD, CTD and ADCP collection, is that data are correct
The premise of transmission, therefore after SD card initialization success, data are specified to the write of the sector of SD card the 10000th, then read the sector
Whether data, the data for contrasting reading are identical with write data, to guarantee that the data for storing are correct.If identical, illustrate
SD card can be normally carried out read-write operation；If it is different, need to reinitialize to SD card.
Fig. 4 gives real-time coupled transfer flow chart.In transmitting procedure, each 10min data block as an entirety at
Reason, buoy main control unit need to perform real-time coupled transfer flow process to each SSM.The figure is that buoy main control unit is obtained to a SSM
The flow process fetched data：Circulation first wakes up HEM until success；Connect SSM after time delay t1, judge whether to connect within the t2 times
Work(, reconnects if connection failure, and double failing then terminates current SSM operations, connects next one SSM, it is to avoid because
Certain SSM failure is impacted to whole link stability；After successful connection, time delay t3 simultaneously sends retrieval command, in the t4 times
It is interior to judge whether load instruction responds, if failure, resends retrieval command, double failure then end operation；Peek
Receiving data after the correct response of instruction, judges whether data receiver is correct, if incorrect, resends peek within the t5 times
Order and judge whether response；Data are stored after data receiver is correct, then the time delay t6 times and sends the mode of secession
Order, judges whether within the t7 times, exits successfully, if failure, resends；After the mode of secession success, time delay t8 is simultaneously closed
Closed walk, so far, completes the cache flush mode to a SSM.
Fig. 5 gives real-time radio station transfer process figure.The response of opposite bank station radio order is integrated in a function, specifically
Flow process is as follows：First judge whether bank station sends order, received if having order；Judge whether the order for receiving is to shake hands to ask
If so, and last 10min data order is asked, if then replying handshake response order, otherwise judges whether it is to ask for data command,
Complete coupled transfer and be stored in SD card, then take out data from SD card and return and reply bank station, otherwise reply empty packet to show
Data are unripe.
Fig. 6 gives buoy main control unit overall workflow figure.Configure in clock, serial ports, unlatching in main control unit
Have no progeny, carry out the initialization flow process of SD card, after SD card initialization success endless loop is entered：A 10min data in cycle criterion
Whether block gathers completes, and data are asked for SSM by coupled transfer if upper 10min collections are completed, and then stores to SD
In card, the collection of next one 10min data blocks is waited to complete after whole end of transmissions；If upper 10min collections are not completed, etc.
It is to be collected to complete.For MCU, if the work of interrupt processing is more, system in case of system halt is easily caused, and communication protocol requirements data are past
The time of returning cannot be greater than 200ms, so in the endless loop of this coupled transfer, adding after the code at interval of 30ms real-time
Radio station transfer process (function), similar to house dog dog feeding operation.
Real-time Transmission in the present invention includes two aspects：One is the real-time of drive marine supplemental characteristic, that is, pass to bank station
Data be nearest ten minutes；Two is the real-time being wirelessly transferred, i.e., for the order that bank station is sent every time, all with 200ms
Within two-way time give a response.
Finally, the present invention realizes drive marine parameter by will inductively transmit in combination with radio station transmits
Real-time Transmission.
