Experimental system and control method for aerostat cable retraction and deployment based on profinet communication

Abstract

The invention discloses an aerostat cable retracting experiment system based on Profinet communication. 1. A cable storage winch and a control system for storing cables, one end of the cable is tied to the load winch, and then bypasses the force measuring pulley, the traction winch and the cable discharge mechanism in turn, and is tied to the cable storage winch; the control system is connected with the cable storage winch respectively. The load winch, traction winch, cable discharge mechanism and cable storage winch are connected and their running states are controlled respectively. The invention utilizes a load winch that can provide load changes to overcome the limitations of the traditional tower suspension heavy load test, uses the load winch to realize the verification of cable discharge speed and operating characteristics under full load conditions, and can simulate the load change of the aerostat.

Description

technical field [0001] The invention relates to a cable retracting experimental system, in particular to an aerostat cable retracting experimental system based on Profinet communication and a control method thereof. Background technique [0002] Lift-off recovery equipment is used for mooring on the ground, mooring in the air, launching into the air and descending to recover the aerostats such as tethered balloons. The aerostats are easily affected by strong winds and convective weather, and their loads will change. The core device is Winch towing system, winch towing system has the characteristics of high reliability, large load, large capacity and anti-interference. [0003] In order to verify the speed performance and load performance of the winch system, it is necessary to provide a load system that simulates the change of the aerostat load in a complex weather environment. The traditional test method is to use a tower to hang heavy objects, but due to the limitation of ...

Problems solved by technology

[0003] In order to verify the speed performance and load performance of the winch system, it is necessary to provide a load system that simulates the change of the aerostat load in a complex weather environment. The traditional test method is to use a tower to hang heavy objects, but due to the limitation of the height of the tower , it is difficult to verify the speed characteristics under full load; in addition, the general winch system often uses serial communication to read and monitor the operating status of the system when it is running. And when serial communication is used, the external wiring between the control system and the inverter is complicated
