Embodiment
Below in conjunction with schematic diagram and concrete operations embodiment the present invention is described further.
See also Fig. 2; The inventive method mainly comprises data acquisition and data processing issuing process; Wherein, Data acquisition is: the collector that is arranged in the data acquisition unit at tidal level station sends to the data A/D converter with the tidal level data analog signal that collects, and is to be transferred to first Big Dipper communication control processor after the digital signal through the data A/D converters with analog signal conversion; The data processing issuing process is: said first Big Dipper communication control processor sends to the tidal level data on the Big Dipper traffic guidance machine of control module based on the big-dipper satellite system; Big Dipper traffic guidance machine again with data transmission to PC; Said PC to the tidal level data filter, curve plotting and processing; Generate standard chart by daily production requirement, Big Dipper traffic guidance machine links to each other with PC, is responsible for its each received tidal level station data of monitoring; Confirm its duty through tide curve; In time arrange the last station of managerial personnel to handle if pinpoint the problems, finally data processed is externally issued, data are sent on second Big Dipper communication control processor of each authorized user in the subscriber unit based on the big-dipper satellite system.
During practical implementation, Taibei bucket satellite communication commander's machine and a PC that is used to receive and issue the tidal level data need be installed in the company computer room, form control module.As total control center; Control module is responsible for carrying out the centralized and unified management of tidal level data; Data to each the tidal level station that receives sends are monitored, judge tidal level data representative duty normally whether, and through each received tidal level station data of Big Dipper traffic guidance machine check; Confirm its duty through tide curve, in time arrange the last station of managerial personnel to handle if pinpoint the problems.Cooperate corresponding software; Control module utilizes PC to realize the issue of reception, processing and the network tidal level information of data: data processing is mainly carried out tidal level data filter, curve plotting and processing; By the chart of daily production requirement generation standard, so that production application; Utilize the communication function of big-dipper satellite; The tidal level information that control module will be handled through Big Dipper traffic guidance machine sends to each authorized user; Guarantee the safety and the paid utilization of tidal level data, Big Dipper commander machine capacity is 100 users, for the dilatation of tidal level system user is later on layed foundation.Data acquisition unit is made up of collector, first Big Dipper communication control processor and data A/D converter; Be used to realize field acquisition, data-switching, data storage and the transmission of tidal level data; Collector can be selected pressure transducer or radar sensor for use, and the simulating signal that collects is transmitted by first Big Dipper communication control processor after converting digital signal into through the data A/D converter again.Control module receives the tidal level data that data acquisition unit collects and process A/D changes through the forwarding of big-dipper satellite.Subscriber unit all is through the use user after authorizing; Like offshore construction boats and ships, surveying vessel, ship for civil use etc.; Set up second Big Dipper communication control processor at each authorized user place, the forwarding through big-dipper satellite receives the tidal level data of crossing through the control module analyzing and processing.
In addition,, can keep original tidal level data receiver formula, promptly in Big Dipper traffic guidance machine, set up a GPRS module or CDMA module, make GPRS pattern, CDMA pattern, big-dipper satellite send isotype and deposit in order not influence production.
Provide a concrete case below, apply the present invention to entrance of Changjiang River deep water fairway dredging work.
The used tidal level of deep water fairway ship dredging construction station, entrance of Changjiang River data transmission adopts the transmission mode of " UHF high frequency+cellular network note " always, receives reasons such as transmission range and electromagnetic environment variation to cause the tidal level data message can't normal transmission.At present; The distance at station such as Ji Gujiao, ox-hide reef is far away; The mode that the employing transfer is transmitted is transmitted by station in the northern groove in real time, when the chance meteorological condition is relatively poor, can't receive the real-time tidal level information at each station; Directly had influence on the tidal level Data Acquisition, and the long-distance transmissions of utilizing the communication function of big-dipper satellite system to solve tidal level information becomes best selection.
Foundation is based on the tidal level infosystem of big-dipper satellite system: tidal level management and control center are set up in (1) in the corporate HQ; Set up HSK-C-100 Big Dipper traffic guidance's machine and relevant device in control center; Control center mainly carries out tidal level data filter, curve plotting; According to the coordinate acquisition of big-dipper satellite, the data of the high precision tidal level after distance weighted processing are provided to the user who is in certain position.(2) before carrying out data acquisition; Transmission system to the tidal level acquisition system is transformed; Guaranteeing under the constant situation of original system, on the tidal level station, loading the big-dipper satellite transmission system, in order not influence production; Still keep original tidal level data receiver formula, i.e. high frequency UHF pattern, CDMA pattern, three types of big-dipper satellite sending modes and deposit.Rewrite the tidal level station software, make its host-host protocol consistent, so that remote transmission with big-dipper satellite.Because the increase of big-dipper satellite electricity consumption; Transform tidal level station electric power system; Have the bank electricity not have need not considering of powerup issue, the power supply at station waterborne adopts two kinds of forms to transform, and can increase the storage battery quantity at tidal level station on the one hand; Also can increase solar panels on the other hand, for the tidal level station provides sufficient working power.(3) on 5 tidal level stations, entrance of Changjiang River (in Waigaoqiao Bonded Zone, horizontal sand, the northern groove, ox-hide reef, Ji Gujiao), respectively set up a HSK-M-200 Big Dipper communication control processor; Other has a HSK-M-200 Big Dipper receiver to use machine as integration test; Each tidal level station promptly is that a tidal level is gathered the center, and tidal level data are sent to control center at regular intervals at interval in the tidal level station.Because the big-dipper satellite system itself has the time service function, multistation tidal level data data " collision " phenomenon in the transmission course can not occur when carrying out the transmission of tidal level data.(4) set up customer group, only relevant tidal level data message is provided customer group in control center's registration.Control center is connected into company's network system; Centralized collection tidal level data; Deposit database in; Central station exploitation network tidal level releasing software platform, workboat or measurement unit can use CDMA/GPRS/3G online visited company tidal level releasing software platform, just can obtain corresponding tidal level data through authentication.
More than specific embodiment of the present invention is described in detail, but the present invention is not restricted to the specific embodiment of above description, it is just as example.To those skilled in the art, any to this equivalent modifications of carrying out based on the tidal level data transmission and the control method of big-dipper satellite system with substitute also all among category of the present invention.Therefore, not breaking away from impartial conversion and the modification of having done under the spirit and scope of the present invention, all should contain within the scope of the invention.
