Problems solved by technology

The above-mentioned existing system is a one-to-one measurement and control system, that is, a measurement and control vehicle performs measurement and control on a UAV. Although the existing system also has a set of auxiliary remote control equipment, it can only be operated when the UAV is in operation. In most cases, the main measurement and control link fails when the distance between the UAV and the measurement and control vehicle is far away (outside the field of vision), and once the failure occurs appears, at which point the secondary remote control device is completely disabled

Embodiment Construction

[0042] The invention relates to a two-vehicle measurement and control system for a coaxial double-rotor unmanned helicopter. As shown in Figure 1, the present invention consists of two sets of ground measurement and control systems and one set of airborne measurement and control systems. The two vehicles can monitor the UAV at the same time, and one of them controls the UAV. The control right of the two vehicles to the UAV is completed by the joint decision-making of the airborne measurement and control system, the ground measurement and control system and the driver.

[0043] As shown in Figure 2, the ground measurement and control system consists of a measurement and control vehicle platform, a flight console, a remote control encoder, a telemetry decoder, a ground monitoring computer, a measurement and control transmitter and a measurement and control antenna. The flight console is connected with the remote control encoder, the remote control encoder and the telemetry decod...

Description

1. Technical field [0001] The invention relates to a measurement and control system, in particular to a measurement and control system for a coaxial double-rotor unmanned helicopter, and belongs to the technical field of measurement and control. 2. Background technology [0002] Unmanned helicopter is a helicopter that uses wireless remote control to control the flight. Compared with fixed-wing aircraft, unmanned helicopters have poor flight stability, rapid flight status changes, and more complicated ground control. Therefore, unmanned helicopters are more important to radio. The remote measurement and control system puts forward higher requirements. The performance and reliability of the measurement and control system are of great significance to ensure the safe flight of unmanned helicopters and the smooth completion of tasks. [0003] The present invention is a dual-vehicle measurement and control system for coaxial dual-rotor unmanned helicopters. The system is based o...
