Special equipment antenna turntable dual-motor control system and method

Abstract

The invention discloses a special equipment antenna turntable dual-motor control system, which mainly includes a central processing unit, and a group consisting of a human-machine interaction interface, an optical fiber transmission unit, a first motor system, and a second motor system which are connected with the central processing unit. The first motor system and the second motor system are eachcomposed of an integrated servo motor, a reducer, an electromagnetic clutch, and a pinion which are successively connected. The two pinions rotate a turntable large gear and an antenna plate to change an antenna azimuth. A dual-motor control method of the system is also disclosed. The system uses a single central processing unit to control the dual motors. The two integrated servo motors operatealternately every 12 hours, thereby greatly prolonging the service lives of the integrated servo motors, reducing the maintenance frequency of workers, improving the reliability of the system, achieving the online switching of the motors, guaranteeing the 24-hours continuous operation of the special equipment antenna.

Description

technical field [0001] The invention relates to the technical field of special equipment, in particular to a special equipment antenna turntable dual-motor control system and a method thereof. Background technique [0002] Antenna turntable is an essential and important part of mechanical scanning special equipment. Its main function is to carry the mechanical scanning action required by the special equipment antenna; at the same time, the antenna turntable is also used as the bearing base of the antenna, bearing the self-weight of the antenna and other loads transmitted by the antenna. [0003] With the increasing number of tasks performed by special equipment, 24-hour start-up work has become a trend, especially in some areas of Tibet, where the average altitude is above 5600 meters, and the staff need to carry oxygen to work normally. In order to reduce the frequency of personnel working on the mountain, special The reliability of the equipment puts forward higher requir...

Problems solved by technology

[0004] In the traditional dual-machine hot standby redundant system, two sets of equipment are in a hot state, and if one fails, the other immediately takes over all tasks, but the investment cost is high, and the two sets of equipment are always working, which reduces the cost of maintenance. The life of the device and the independent configurations will also affect each other; secondly, the use of heartbeat detection and key data mirroring mechanism will make the switching time of the two CPUs too long, and under the interference of the complex electromagnetic environment, the The communication between them will fail, which will increase the difficulty of maintenance, and will also cause the equipment to stop, which will bring serious consequences, and the reliability will be greatly reduced compared with theoretical calculations.

In addition, the traditional dual-machine hot standby redundant system uses an overrunning clutch. When there is a strong wind in the natural environment and the antenna speed exceeds the motor speed, the overrunning clutch will disengage. At this time, the antenna will not be controlled by the motor, and the antenna cannot be completed. GPS

At the same time, the traditional use of pulse, analog, and digital to control the rotation of the antenna, the hardware device connection is complicated, and the anti-interference and real-time performance are poor.
