Aerostat cable take-up and pay-off experiment system based on Profinet communication and control method thereof

Abstract

The invention discloses an aerostat cable take-up and pay-off experiment system based on Profinet communication. The aerostat cable take-up and pay-off experiment system comprises a load winch used for simulating an aerostat load, a force measuring pulley used for conveniently measuring cable tension, a traction winch used for pulling a cable, a cable arrangement mechanism, a cable storage winch used for storing the cable and a control system. One end of the cable is tied on the load winch, sequentially bypasses the force measuring pulley, the traction winch and the cable arranging mechanism and is tied on the cable storage winch; the control system is connected with the load winch, the traction winch, the cable arrangement mechanism and the cable storage winch and controls the operation states of the load winch, the traction winch, the cable arrangement mechanism and the cable storage winch. The load winch capable of providing load changes is used for overcoming the limitation of a traditional tower suspended weight load experiment, the load winch is used for verifying the cable arrangement speed and operation characteristics under the full-load condition, and aerostat load changes can be simulated.

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 ...

[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
