Description

Beeacon satellites location and remote measuring and controlling device

Affiliated technical field:

The utility model relates to a kind of location of aids to navigation waterborne to be followed the tracks of and the remote measuring and controlling device, is specially adapted to administrative authority (Waterway Bureau, marine board etc.) the widely distributed various navigation marks in inland river, lake and navigation channel, coastal waters are carried out concentrated, round-the-clock, high precision and real time remote position monitoring and control.

Background technology:

Along with development of science and technology, today, the luminous and energy technology of navigation mark was significantly improved.But the mode of manually regularly stepping on the mark inspection is still adopted in the maintenance of navigation mark mostly, and some important sign also must be guarded by the special messenger.Some Pharos Remote Sensing and Control System input tests are early also arranged both at home and abroad, mainly adopt satellite communication or VHF/UHF frequency wireless data radio station mode to realize the remote measuring and controlling of navigation mark, but do not use owing to the problem below existing has large-scale popularization.

1. satellite communication is costly; Data radio station needs oneself to build base station and demand frequency, and investment is big, and the operation maintenance expense is high, and coverage rate is little, and power system capacity is little, and transmission speed is slow; The power consumption of remote measuring and controlling transmitter is big, disturbs strong.

2. this type systematic of great majority does not possess accurate positioning function, can not solve the displacement and the drift problem of buoy.

Summary of the invention:

In order to overcome the problem of wireless transmission approach in the existing system, the utility model adopts GSM public's digital cellular mobile communication systems, specifically is the remote measuring and controlling that adopts the short message service realization navigation mark of GSM.As the present whole world and China all is maximum unified mobile radio communication, the user does not need own networking (comprising numerous base stations, exchange system etc.), can reduce investment outlay and operation and maintenance expenses usefulness, network coverage is big, expansion is convenient, the terminal transmitter disturbs little, little power consumption, and communication speed is fast, and the technical development potentiality are big.

The utility model has adopted the GPS global satellite positioning that navigation mark is implemented accurately location simultaneously, has realized the tracking of displacement warning and drift.Technical scheme:

The utility model has mainly utilized GSM digital mobile cellular telecommunication technology, GPS global satellite positioning and GIS geographical information technology.At first obtain the status information of navigation mark by GPS receiver of installing on the navigation mark and various sensor, the longitude and latitude, warning and the various running parameter that comprise navigation mark, the gsm communication module that these information are installed on by navigation mark after single-chip microcomputer is handled sends to Surveillance center in GSM short message mode, the information that Surveillance center's computing machine receives, handles and store navigation mark, managerial personnel can inquire about intuitively and operate on the GIS electronic chart by network, realize that the location of navigation mark is followed the tracks of and telemetry function.Surveillance center also sends to steering order on the monitoring equipment of navigation mark by gsm communication system on the other hand, realizes distant control function.Effect:

Adopt the utility model device, the Compensation Liability for Damage Caused by the Fault in the Administration of Aids to Navigation personnel just can realize round-the-clock, high precision, locating and monitoring intuitively and anywhere or anytime to the working condition of navigation mark at machine room, in time handle when navigation mark breaks down, guarantee that the navigation channel is unimpeded, can also save the maintenance cost of navigation mark greatly.Simultaneously, because gps antenna and receiver have been installed, can realize global positioning satellite on navigation mark, solve the displacement problem of buoy navigation mark, when navigation mark floats, at the GSM areal coverage, no matter how far the distance of drift has, navigation mark that all might finding lost.

Because the utility model adopts the wireless transmission platform of gsm communication system as pharos remote sensing and control, therefore the distance of capacity, transfer rate and the monitoring of system depends on capacity, speed and coverage rate (network in the GSM whole nation of GSM, capacity is big, transfer rate is greater than 9600 baud rates and in fast development), and adopt the VHF/UHF private network because channel limited (being generally tens to 20), coverage is generally tens kilometers, and data rate generally is no more than 2400 baud rates; The user also needs to build the maintain communications base station; The terminal device power consumption is than GSM terminal big (working current in VHF/UHF radio station is several the peace to tens peaces when being in the emission duty, and the GSM terminal is tens to more than 100 milliamperes); Reliability, networking property and extendibility do not have GSM good yet simultaneously.
