中文拼音 [tōngxìnjūtiānxiàn]
通信車天線
英文
over-car antenna-
The motion carriers such as the automobile, trains, war vessels, the plane and so on, are in flux by their position and azimuth, if want kepting satellitic message and taking over satellitic signal, must adopt the platform system of tenaclous tracking satellite antenna
汽車、火車、艦船、飛機等運動載體的位置和姿態不斷的在變化，要保持與衛星的通訊聯系和接收衛星視頻等信號，就必須採用衛星天線穩定跟蹤平臺系統。Through the reaserch of the paper, a satellite transmission and television signal incepting system using stabilization platform which is used on the moving carrier ( vehicle, boat, ship etc ) has been designed. it uses an embedded system which is based on arm7tdmi core microcontroller and c / os - ii real - time operating system to control and scout the movement of the antenna stabilization platform, can realize the real - timable and reasonable stance control of the antenna, and then can realize the real - time communications and the signal receiving between the satellite and the moving carrier
3 .通過論文的研究，開發出了一種用於移動載體（車、船、艦等）上利用穩定平臺來進行衛星通信與電視信號接收的系統? ? 「動中通」移動載體衛星通信與電視接收系統。該系統採用基於arm7tdmi核微控制器和c / os - ii實時操作系統的嵌入式系統來控制天線穩定平臺的運動，可以實現對天線實時而合理的姿態控制，從而實現移動載體與衛星之間的實時通信和信號接收。Unfortunately, venus express happens to be in a phase of its mission in which the geometry of the sun, spacecraft, and earth require it to use the smaller of its two dish antennas for communications ( because using the larger one would expose parts of the spacecraft to unacceptable levels of solar heating )
不幸的是， 「金星快車」所處的與太陽和地球間的位置剛巧使其只能用兩個碟型天線中較小的一個進行通信（因為使用大天線會使飛船的一部分暴露在不可接受的陽光暴曬下） 。Secondly, the article begins with changing the original chip and selects a new type of chip, max1479, which has more emission power, constitutes a new communication protocol, and designs the circuit and program. in the end, this article analyses the influence of environment on the antenna. meanwhile, it also analyses characteristic of the antenna by using electromagnetic theory, and then designs a kind of inverted - f antenna
其次，本文從射頻晶元改型入手，選用一款專用於汽車電子並具有更高發射功率的射頻晶元max1479 ，重新制定通信方案，設計硬體電路並編程調試;最後，本文分析了環境因素對天線輻射的影響，應用天線和電磁場理論對天線的特性進行分析，設計一種倒f型天線和螺旋天線相結合的天線結構，並用hfss軟體和cst軟體模擬。Zhejiang meiyu motorcycle fittings co., ltd. was created from teamwork of motorcycle professionals and inventors with rich experience within the industry from china business world. after a decade of development, now we have a registered capital of nearly usd 1, 500, 000, staff of more than 200 and an annual sale of usd 8, 000, 000. since 1994, we have been manufacturing motorcycle plastic parts, motorcycle luggage boxes and top quality helmets
