Embodiment Construction

[0039] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0040] Such as figure 1 Shown is the structural block diagram of the dual-antenna switching verification and signal receiving device of the present invention. It can be seen from the figure that the device includes an electronic radio frequency switch, a low-noise amplifier, a receiving channel unit, a despreading and channel decoding unit, a source decoding synchronization unit, and a power conversion unit, control unit and display panel.

[0041] The electronic radio frequency switch selects antenna A to work or antenna B to work, and outputs the gating information to the display panel for display, and at the same time outputs the radio frequency information received from the gating antenna A or antenna B to the low noise amplifier. The low noise amplifier amplifies the radio frequency signal received from the electronic radio frequency switc...

Abstract

The invention relates to a double-antenna changing verifying and signal receiving device and a realizing method thereof. A receiving channel unit outputs one path of intermediate-frequency signals obtained from a down converter to a spreading and channel decoding unit, and outputs another path of intermediate-frequency signals after demodulation to a display panel, the spreading and channel decoding unit carries out spreading and demodulating on the intermediate-frequency signals, and carries out frame synchronization processing and scamble decoding processing, an information source synchronization unit can carry out uncompressing processing and digital video conversion on the intermediate-frequency signals under action of synchronizing signals, and the display panel carries out contrast on energy of the signals after the demodulation and output by the receiving channel unit with gating signals sent by an electronic radio frequency switch so as to verify whether an antenna A and an antenna B are changed correctly. The device is simple in structural design, realizes short distance monitoring on antenna signals, improves accuracy of the antenna signals monitoring after the antennas are installed, and has excellent confidentiality and anti-interference.

Description

technical field [0001] The invention relates to the technical field of measurement and control, in particular to a dual-antenna switching verification and signal receiving device and an implementation method thereof. Background technique [0002] For a general wireless receiving system, such as a wireless transceiver or a radio frequency receiver, the antenna has been integrated into the receiving system before leaving the factory. There is little chance that the user will add another antenna to the receiving system. However, in other wireless receiving systems, such as the global satellite navigation system receiving system, an antenna interface is provided for users to insert another antenna. The advantage of inserting another antenna is that the wireless receiving system can still provide better signal reception even when the strength of the received transmission signal is weak. However, its disadvantage is that the antenna integrated into the wireless receiving system ...
