Description

Technical Field

[0001] This invention relates to the field of antenna test platform technology, and in particular to a distributed control system and device for an antenna test platform. Background Technology

[0002] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium (usually free space), or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves. Engineering systems that utilize electromagnetic waves to transmit information, such as radio communication, broadcasting, television, radar, navigation, electronic warfare, remote sensing, and radio astronomy, all rely on antennas. Antennas need to be tested and adjusted before use or during regular maintenance to determine their optimal signal reception state.

[0003] An antenna consists of a transmitter and a receiver, and the relative positions of the transmitter and receiver affect the quality of the antenna's signal transmission and reception. In the existing technology, the testing process of antennas is usually carried out on a test bench. Such test benches have relatively simple functions, with only simple debugging fixtures. During the debugging process, it is difficult for the debugging personnel to simulate the scene when the antenna is working in the field, and it is impossible to realize various changes in the relative positions of the transmitter and receiver, which delays the debugging progress and affects the debugging results. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a distributed control system and device for an antenna test platform to overcome the problems mentioned above, which solves the above problems.

[0005] The technical problem solved by this invention is achieved through the following technical solution:

[0006] A distributed control system and device for an antenna test platform includes a test antenna fixed within a concave surface of a reflector. It also includes a lower tripod and an upper tripod, and a hinge joint bolted to the lower tripod. A platform attitude adjustment rod is hinged to the hinge joint, the upper end of which is hinged to the hinge joint fixed to the lower end of the upper tripod. An elevation adjustment rod is hinged to one end of one arm of the upper tripod, and hinge modules are hinged to the other two ends. The back of the reflector is hinged to the hinge modules and the front end of the elevation adjustment rod. An external frame is welded and fixed to the rear of the reflector. The external frame is used to mount and fix an anti-interference shield, which includes a hemispherical unfolding and retracting structure.

[0007] Preferably, the anti-interference cover includes a spherical frame portion and a gear assembly for driving the spherical frame portion. The spherical frame portion includes a rear main support bone and a front main support bone that are hinged to each other. An arc-shaped support bone is hinged to the front end of the rear main support bone and the front main support bone. A half support bone is hinged to the front end of the support bone. The hinge points on the outer sides of the rear main support bone and the front main support bone, the hinge points between the rear main support bone, the front main support bone and the support bone, and the hinge points between the support bone and the half support bone are all fixed to the anti-interference cloth covering the outer side of the spherical frame portion by adhesive.

[0008] Preferably, the length of the semi-support bone is half that of the support bone, and the curvature of the semi-support bone is consistent with that of the support bone.

[0009] Preferably, the gear assembly constituting the anti-interference cover includes two symmetrical gear rotating clamping plates, with a first gear and a fourth gear, as well as a third gear and a second gear rotatably disposed between the two gear rotating clamping plates, and the first gear and the fourth gear being connected as one unit by a sleeve.

[0010] Preferably, a fifth gear and a sixth gear are rotatably disposed between the two symmetrical gear rotating clamping plates, and the fifth gear and the sixth gear are coaxial.

[0011] Preferably, the second gear and the third gear rotate coaxially, the second gear meshes with the first gear, so that the fourth gear rotates together with the first gear under the action of the sleeve, and the fourth gear meshes with the sixth gear.

[0012] Preferably, the fifth gear and the third gear, which rotate coaxially with the sixth gear, mesh with each other. The front main support is fixed to the front end of the inner core rod, and the rear main support is fixed to the front end of the outer sleeve rod. The inner core rod passes through the hollow tube of the outer sleeve rod. The sixth gear is fitted on the outside of the outer sleeve rod and fixed by a key. The fifth gear is fitted on the outside of the inner core rod and fixed by a key.

[0013] Preferably, a cover bone is hinged at the hinged front end of the half cover bone, which encircles the cover bone and the outside of the half cover bone. The midpoint of the hinged cover bone extends outward, and the rear half of the cover bone is provided with a double-rounded groove, in which the sliding ball joint in the middle of the hinged cover bone slides.

[0014] Preferably, the front end of the cover bone has an integrally formed T-shaped structure with magnetic attraction. The sixth gear and the fifth gear drive the outer outer rod and the inner core rod to rotate, which pushes the two cover bones forward and causes the T-shaped structures at their front ends to abut against each other to complete the locking after wrapping.

[0015] The advantages and positive effects of this invention are: the height and horizontal position of the reflector can be controlled by the linkage adjustment of multiple sets of platform attitude adjustment rods; the elevation angle of the reflector can be quickly adjusted by the extension and retraction of the elevation adjustment rod; when adjusting the attitude position of the test antenna, it can also work with the anti-interference cover to effectively adjust and block interference signals from different directions, which is convenient for multi-directional signal testing outdoors and is more convenient and efficient than existing testing methods.
