Abstract
The invention relates to an automatic arraying control device of a log-periodic antenna array and an arraying method thereof. The automatic arraying control device comprises an antenna lifting mechanism, the log-periodic antenna array, a plurality of plug pin driving mechanisms, a plurality of pin hole detection mechanisms, a plurality of antenna folding and unfolding mechanisms and a control module. The lifting mechanism comprises a supporting table and a lifting arm. The lifting arm comprises a plurality of arm shafts, every two adjacent arm shafts are movably connected and pin holes are formed in the arm shafts. The log-periodic antenna array comprises a plurality of layers of antennas, each layer of antenna is provided with a connecting part, the connecting part of each layer of antenna is provided with a plug pin and each layer of antenna is movably connected with one arm shaft. Each plug pin driving mechanism is arranged on one connecting part and is connected with the plug pin.The pin hole detection mechanisms are installed at the position close to the plug pins of the connecting parts. Each antenna folding and unfolding mechanism is installed on one layer of antenna. The control module is electrically connected with the pin hole detection mechanisms, the plug pin driving mechanisms, the antenna lifting mechanism and the antenna folding and unfolding mechanisms. Automatic and accurate array forming can be realized and safety and reliability can be achieved.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to an automatic formation control device and formation method of a logarithmic periodic antenna array. Background technique [0002] The short-wave antenna refers to the transmitting or receiving antenna working in the short-wave band (3-30MHz). Shortwave mainly uses ionospheric reflection propagation for communication, so it is not restricted by network hubs and relay conditions, and is one of the important means of modern long-distance radio communication. Antenna bandwidth and antenna gain are important indicators of the antenna, and they are also key indicators that restrict the communication distance of the antenna. [0003] In order to meet the requirement that the antenna has both large bandwidth and high gain, multiple pairs of log-periodic antennas are often combined in a certain way, then there will be a coupling relationship between the antennas, so the a...
