Abstract
Provided is a transmitting antenna used for a flood discharge alarm system, comprising a housing and a support. Two ends of the housing are provided with antenna oscillators, the lower part of the housing is provided with a support, and the end part of the support is provided with an adapter which is in connection with a transmission cable arranged in the support. The advantages are as follows: first, the circuit possesses an impedance transformation function, and can simplify the adjustment of a transmitting antenna to easily meet coupling requirements; second, system technical indexes are substantially raised and antenna gain is doubled; third, the work frequency band is wide and does not need to be debugged at an installation construction site; and fourth, transmission loss and reflection loss are small, and a covering scope is effectively enlarged.
Description
Technical field the utility model relates to communication equipment accessory, specifically a kind of transmitting antenna for flood discharge warning system.
Background technology flood discharge warning system is digital radio move instruction broadcast system, is widely used in recent years in all kinds of hydroelectric stations, and flood discharge is reported to the police and brought into play great effect.Transmitting antenna is the vitals of this system, is responsible for the transmitting of various signals, and existing transmitting antenna exists following defect: the one, and antenna adjustment workload is large, and Matching and modification is more difficult; The 2nd, the gain of antenna is low, and effective coverage range is little, often causes alarm point received field strength inadequate in use procedure, affects warning effect; The 3rd, the variation of weather and natural environment are influential to launching, and cause signal receiving end poor stability, have limited remote transmission.Therefore, how to improve the gain of transmitting antenna, extending bandwidth, makes the Installation and Debugging of job site more convenient, is the key that guarantees that flood discharge warning system can work.
Summary of the invention the utility model, for the problems referred to above, provides a kind of transmitting antenna for flood discharge warning system.
This transmitting antenna for flood discharge warning system, comprise shell, support, ferrite bead, antenna oscillator and cable, it is characterized in that, the two ends of shell are provided with antenna oscillator A and antenna oscillator B, the bottom of shell is provided with support, bracket end is provided with adapter, and the transmission cable arranging in support is connected with adapter, and transmission cable is comprised of outer conductor, polyvinyl chloride insulation body and heart yearn; Enclosure is provided with ferrite bead, is wound with cable on ferrite bead, and cable is comprised of outer conductor, polyvinyl chloride insulation body and heart yearn, and the two ends of cable are respectively C end and D end; The heart yearn of cable C end is connected antenna oscillator A with after the heart yearn parallel connection of transmission cable; The heart yearn of cable D end is connected with support with the outer conductor of cable C end, the outer conductor of transmission cable respectively, and the outer conductor of cable D end connects antenna oscillator B.
The adapter of the power of transmitter output by transmission feeder and the antenna holder end feed that is connected, transmits after the winding cable on ferrite bead carries out unbalanced-balanced conversion, then by antenna oscillator to air-launched.
Advantage of the present utility model: 1, this circuit has impedance transformation function, can make the adjustment of transmitting antenna simplify, and coupling easily meets the demands.2, systematic technical indicator improves greatly, and antenna gain is original twice.3, working band is wide, need to not debug in installation building site.4, loss and reflection loss are little, have effectively expanded coverage.
