Description

Fixed base station satellite communication antenna equipment
Technical Field
The invention relates to the technical field of satellite communication antennas, in particular to a fixed base station satellite communication antenna device.
Background
A base station, i.e. a public mobile communication base station, is an interface device for accessing a mobile device to the internet, and is also a form of a radio station, and refers to a radio transceiver station for performing information transmission with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area. With the development of mobile communication network services towards datamation and packetization, the development trend of mobile communication base stations is inevitably broadband, large coverage area construction and IP, control signaling, voice call or data service information on the core network side is sent to the base stations through the transmission network (in 2G and 3G networks, signals are first transmitted to the base station controller and then transmitted to the base stations), the signals are processed by baseband and radio frequency on the base station side and then transmitted to the antennas through radio frequency feeders for transmission, the terminals receive radio waves transmitted by the antennas through radio channels and then demodulate out signals belonging to the terminals, the reverse signal transmission flow is opposite to the forward flow direction, but the principle is similar, and each base station can contain one or more sectors according to the connected antenna conditions. The coverage area of a base station sector can reach hundreds of kilometers to dozens of kilometers, but in an area with dense users, the coverage area is usually controlled, interference on adjacent base stations is avoided, and the base band and radio frequency processing capacity of the base station determines that the physical structure of the base station consists of two parts, namely a base band module and a radio frequency module. The base band module mainly completes the functions of modulation and demodulation of a base band, allocation of wireless resources, call processing, power control, soft switching and the like, the radio frequency module mainly completes conversion between an air radio frequency channel and a base band digital channel, and the functions of amplification, receiving and sending of the radio frequency channel and the like, the satellite antenna is a large pan which is a metal paraboloid and is responsible for reflecting satellite signals to a feed source and a high frequency head which are positioned at a focus, and the satellite antenna is used for collecting weak signals transmitted by a satellite and removing noise as far as possible. Most antennas are generally parabolic, some multi-focus antennas are formed by combining a spherical surface and a paraboloid, satellite signals are concentrated to the focus of the antennas after being reflected by the paraboloid, with the rapid development of a mobile communication network, currently, the number of the antennas stored in three operators is more than 350 ten thousand, and with the lapse of time, functional parameters, antenna azimuth angles and elevation angles of base station antennas can be changed, so that the actual coverage area of the base station antennas deviates from the planned range, the communication quality is directly influenced, particularly in coastal typhoon-prone zones, and the base station antennas are changed more frequently. Therefore, real-time monitoring of the antenna azimuth angle is particularly important, but due to the lack of effective monitoring means for the working condition, the management of the working parameters of the base station antenna system is always a difficult point of maintenance. With the continuous expansion of the 4G network scale, the antenna management is carried out by the traditional inspection means, not only a large amount of manpower and material resources are consumed, the maintenance cost is high, but also the real-time performance and the accuracy of data acquired on site are poor, the GNSS precision direction finding technology is one of the key technologies for providing precision position service for a global satellite navigation system, and is widely applied to mechanical control of driving examination, precision agriculture, unmanned aerial vehicles and the like at present, the GNSS direction finding technology is utilized, the carrier phase and pseudo range data acquired by two receivers on a carrier are taken as main observed values to carry out differential solution, the whole-cycle ambiguity of the carrier phase is estimated, high-precision course information can be obtained in real time, the operation efficiency is greatly improved, the operation cost is reduced, the antenna is a converter, the antenna converts guided wave transmitted on a transmission line into electromagnetic wave transmitted in a unbounded medium or carries out reverse conversion, is a component used for transmitting or receiving electromagnetic waves in radio equipment, as mobile communication gradually develops to the depth and the breadth, the application environment of the antenna becomes more and more complex, and the installation requirement of the antenna becomes more and more severe. The inconvenient angle regulation of current antenna mounting structure, installation and use are comparatively limited, and inconvenient staff maintains the detection, are unfavorable for using widely.
