Problems solved by technology

[0005] However, the existing airship control system still has the following disadvantages: First, the control distance is short: when using analog-to-digital conversion, digital-to-analog conversion, and DIO to achieve control, there is no problem within a distance of several meters or even more than ten meters.
Although this system can partially solve the problem of short transmission distance, its transmission distance can only reach about 100 meters, which cannot meet the flight control requirements of giant airships with a spatial scale of more than 100 meters, and the control system cannot adapt to high altitudes for a long time. ultra-low temperature environment

Embodiment 1

[0038] see Figure 4 , the airship control system in this embodiment uses a fiber optic ring network. The digital transmission bus adopts optical fiber. The airship controls multiple acquisition drive units connected end to end with the core computer to form a ring control system.

Embodiment 2

[0040] see Figure 5 , the digital transmission bus of the airship control system still uses optical fiber, and the core computer and acquisition drive unit are connected to an optical fiber switch through the optical fiber interface. Use fiber optic switching to realize the transmission of collected information and control commands. Ground telemetry remote control, temperature control box, sensor, atmospheric computer, inertial navigation, GPS / BD2, vertical gyro, magnetic compass, etc. are still connected with the core computer by serial port and RS422. The temperature control box and sensors here are used to control the temperature of the pod, which is similar to the function of the environmental control module of the acquisition drive unit. Through this control system, the distance between each acquisition and control point of the airship can be extended to a distance of tens of meters or even hundreds of meters. Especially after the digital transmission bus uses optical f...

Embodiment 3

[0042] see Image 6 , The digital transmission bus adopts RS485 / RS422 bus. The acquisition drive unit and the core computer adopt a point-to-point connection. Since the bus adopts a differential transmission / reception mode and has a certain common-mode interference suppression capability, the communication distance can reach thousands of meters.

Abstract

The invention discloses a distribution airship control system. The system comprises at least one collection driving unit, a core computer and at least one digital transmission bus, wherein the collection driving unit is distributed on the airship, so that the environment and operation state information of the airship can be collected and can be transmitted to the core computer through the digital transmission bus after the information is converted into a digital signal on the one hand, and on the other hand, a control command of the core computer can be received, and an actuation mechanism is controlled to act; the core computer is positioned in the pod of the airship, and the environment and operation state information of the collection driving unit is received through the digital transmission bus, and the control command is transmitted to each collection driving unit through the digital transmission bus after the information is processed. The airship control system has strong flexibility and expandability due to the distribution collection driving and concentrated management control mode.

Description

technical field [0001] The invention relates to an airship control system, in particular to a distributed airship control system adopting distributed acquisition drive and centralized management control, belonging to the technical field of airships. Background technique [0002] An airship is a lighter-than-air aircraft whose lift-off principle is the same as that of a balloon, but capable of powered navigation and maneuvering. Airships generally have a huge airbag and corresponding propulsion and control systems. The airship lifts into the air by filling the airbag of the hull with a gas lighter than air (such as helium, etc.), drives the propeller with the engine to push the hull, and controls the navigation direction with the stern rudder surface. Modern airships are widely used in aerial surveys, photography, advertisements, lifesaving and aviation sports. [0003] An airship is a complex integrated system, usually including multiple subsystems such as structure, power...
