Abstract

The invention relates to an antenna lifting control device and control method. The antenna lifting control device includes a support platform, a lifting arm hinged to the support platform at one end,a lifting arm driving mechanism hinged to the support platform and the lifting arm at the two ends respectively, an antenna hinged to one end, away from the support platform, of the lifting arm, and an antenna driving mechanism hinged to the lifting arm and the antenna at the two ends respectively. According to the antenna lifting control device, the lifting arm driving mechanism extends or contracts to drive the lifting arm to rotate relative to the support platform so as to drive the antenna to rise or fall, the antenna driving mechanism extends or contracts to drive the antenna to rotate relative to the lifting arm, and the direction of rotation of the antenna driven by the antenna driving mechanism is opposite to the direction of rotation of the lifting arm driven by the lifting arm driving mechanism. Thus, the center of gravity of the antenna does not change dramatically in the rising and falling process of the antenna in bad environments, overall shaking caused by dramatic changeand the influence of dramatic change on the life of the antenna or mechanism are avoided, and the rising and falling process of the antenna can be stable, safe and reliable.

Description

technical field

[0001] The invention relates to the technical field of communication equipment, in particular to an antenna lifting control device and a control method. 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. Usually, the lower the frequency, the larger the size of the antenna. The maximum size of a large-scale short-wave antenna can reach 50 meters, and the distance between the antenna and the ground is required to be farther. Generally, the short-wave antenna requires a minimum distance of 12.5 meters from the ground, and requires no any covering.

[0003] Considering the large size of the short-wave antenna and its height from the ground, the inconvenience...
