Abstract
The utility model discloses a water conservation flood prevention monitoring terminal based on a Beidou satellite. The water conservation flood prevention monitoring terminal comprises an antenna module, a radio frequency module, a base band module and a power module, wherein the base band module comprises a base band signal processing module and an encoding and decoding control module, and the antenna module, the radio frequency module, the base band module and the power module are connected in sequence. The base band module and the power module are integrated on a printed circuit board (PCB). According to the water conservation flood prevention monitoring terminal based on the Beidou satellite, the Beidou satellite is used for communications. When the water conservation flood prevention monitoring terminal based on the Beidou satellite is used for transforming the existing station system, Beidou communication type user terminals just need to be additionally disposed, and thus the water conservation flood prevention monitoring terminal is small in size, convenient to install and maintain and free of increasing novel civil engineering cost. When the water conservation flood prevention monitoring terminal based on the Beidou satellite is used for increasing novel monitoring stations, site selection of remote telemetry stations is free and free of influences of geographical conditions and mobile signal coverage. Meanwhile, due to the fact that multi-point users of Beidou satellite communications are concurrent, communication capability is powerful, 500,000 user terminal communication requests can be processed simultaneously at the most, and thus a channel congestion phenomenon in clock measuring and reporting can be well overcome.
Description
Technical field
The utility model belongs to satellite communication, and Flood Prevention monitoring field is specifically related to satellite communication terminal---Big Dipper communication type subscriber computer.
Background technology
Beidou satellite communication system is the satellite communication system with perfect knowledge property right of China's independent research.This system signal wide coverage can realize the whole of China's Continental Area, the non-blind area communication of peripheral coastal and offshore area area.CDMA Direct Sequence Spread Spectrum Communication system is adopted in big-dipper satellite communication, and signal transmission antijamming capability is strong, and transmission error rates is low.Can extensively be applied to the national economy field of water conservancy, meteorology, traffic, electric power, forestry and ocean.
China's Flood Prevention monitoring information transmission mode mainly contains GSM note, program-controlled telephone (PSTN), ultrashort wave (USW) (VHF) and marine satellite C (Inmarsat-C) etc. at present, and as the single transmission mode, they have the use limitation of self.
The GSM note is subjected to the impact of movable signal, can only use in the movable signal overlay area.
PSTN adopts circuit exchange mode to communicate, and large and adopt under the modulator-demodular unit condition in power system capacity, system is ageing not high, and PSTN belongs to the wire communication mode, and transmission line is long particularly when remote districts, builds maintenance cost high.
The transmission of VHF signal is subject to stopping of massif, pile, and need to set up multistage relay station when growing Distance Transmission, and civil engineering costs is high, and system reliability descends.
The Inmarsat-C power system capacity is limited, and is concurrent indifferent, constantly the communication blocking phenomenon can occur at integral point.Its communication terminal price will exceed about one times than Big Dipper communication terminal, and operating charges is also higher.
How can realize Flood Prevention monitoring information transmission security, reliable, stable, can reduce the construction and maintenance expense again, be the problem that solution is badly in need of in China's Flood Prevention monitoring.
The utility model content
Problem to be solved in the utility model provides a kind of cost Flood Prevention monitoring transmission equipment low, stable and reliable for performance, makes the transmission of Flood Prevention monitoring information not limited by geographical environment, weather conditions, movable signal covering area range.
For achieving the above object, the technical scheme that adopts of the utility model is:
Flood Prevention monitoring terminal based on big-dipper satellite, include Anneta module, radio-frequency module, baseband module, power module, it is characterized in that: described baseband module comprises baseband signal processing module, encoding and decoding control module, described Anneta module, radio-frequency module, baseband module, power module connect successively, wherein, baseband module and power module are integrated on the pcb board.
Described Flood Prevention monitoring terminal based on big-dipper satellite is characterized in that: the voltage range of described power module is+and 9V～+ 36V.
Described Flood Prevention monitoring terminal based on big-dipper satellite is characterized in that: respectively install one in telemetry station and the central station based on the Flood Prevention monitoring terminal of big-dipper satellite.
Described Flood Prevention monitoring terminal based on big-dipper satellite, it is characterized in that: the hydrographic data of the RTU that the Anneta module of the big-dipper satellite Flood Prevention monitoring terminal in the described telemetry station receives is encoded into Big Dipper protocol format through the encoding and decoding control module with it, reaches baseband signal processing module; Encoding and decoding control module in the described central station Big Dipper data of being responsible for decoding are reduced to the Hydrologic Data Format of RTU with it, are sent to flood control monitoring platform interface by the RS232 serial ports.
Principle of work of the present utility model: select big-dipper satellite communication at communication mode, the level sensor of flood control detection platform and rain sensor are finished respectively the collection of water level information and rainfall information and are transferred to telemetry station, through realizing the coding of hydrographic data in the telemetry station, launch according to Big Dipper frequency again, signal is forwarded to central station through satellite system (the user's identification and the information process that contain ground central station), decoding through the encoding and decoding controller, signal is reduced into the raw data of telemetry station, finally monitoring platform upper computer software shown.
Useful technique effect of the present utility model is:
1, adopt big-dipper satellite communication, be used for existing station system is transformed, then only need set up Big Dipper communication type user terminal, volume is little, and is convenient for installation and maintenance, without newly-increased civil engineering costs; Be used for newly-increased monitoring station, then so that the telemetry station addressing is freer, be not subjected to the impact of geographical environment, movable signal coverage rate.Simultaneously, the multiple spot user concurrent communication capacity of big-dipper satellite communication is strong, and maximum can be processed 500,000 user terminal communication requests simultaneously, the channel jam when can be good at overcoming integral point and observing and predicting.
2, by the different software codec agreement of customization in single-chip microcomputer, so that Big Dipper communication type subscriber computer not only can be used in the Flood Prevention field, can also be used in the fields such as electric power, traffic, meteorology, forestry, fishery.
