Antenna drive control unit

Abstract

The invention provides an antenna drive control unit which comprises a control card, an AC / DC power supply module, a first azimuth relay, a second azimuth relay, a first pitch relay, a second pitch relay, a first azimuth contactor, a second azimuth contactor, a first pitch contactor, a second pitch contactor, an azimuth air circuit breaker and a pitch air circuit breaker. The antenna drive control unit can receive a control command from a host computer, collects the antenna seat status information, runs a loop control algorithm, outputs the control command of an azimuth drive unit and a pitch drive unit to provide power supply for the azimuth drive unit and the pitch drive unit, collects the status information of the azimuth drive unit and pitch drive unit, and reports the status information to the host computer. The antenna drive control unit acts as the connecting bridge between the host computer and an antenna drive unit. Isolation between a control electric signal and a power electric signal of an antenna servo system is realized to ensure the system safety and reliability.

Description

technical field [0001] The invention relates to the field of servo control of a telemetry system, in particular to the drive control of a large-scale antenna servo system on a moving base platform. Background technique [0002] In the telemetry system, in order to increase the working distance of the system, a large-diameter parabolic antenna is usually used. In order to meet the telemetry requirements of sea targets, the telemetry system usually needs to be installed on the base of a moving platform such as a ship, and a higher tracking control accuracy of the servo system is proposed. requirements. The servo system is an important part of the large-scale antenna telemetry system. Its main function is to enable the receiving antenna to capture the target and continuously track the target with a certain accuracy, so that the target is always near the center line of the main beam, so that the target can be continuously and reliably with the maximum receiving gain. Receive te...

Problems solved by technology

[0003] Large-scale antenna telemetry systems usually need to be driven by high-power motors to meet the load capacity. At present, the commonly used high-power motors are bulky, and they need to occupy a large space when installed inside the antenna base, resulting in increased volume and weight of the antenna base.

In the antenna telemetry system, the larger the antenna aperture, the narrower the receiving beam width. In order to prevent the target from being lost, the antenna servo system is required to have higher tracking accuracy to achieve real-time tracking of the target. With the increase of the antenna aperture and the increase in the volume of the transmission mechanism, the The antenna servo system driven by a single motor is difficult to achieve high-precision control
