Description
Technical field
A kind of control system of hawser recovery is the utility model is related to, in particular it relates to a kind of cable for captive balloon
The control system of rope recovery.
Background technology
The existing power supply mode of captive balloon is to be connected to ground by ground anchoring system using optoelectronic composite cable rope
Electric power system, optoelectronic composite cable rope need to bear the working pulling force from captive balloon number in space-time ton during folding and unfolding；Again
The pulling force of hawser is reduced to tens kilograms to protect hawser by recovery system of going up to the air (also known as force-reducing device)；While hawser is also
Meet the required braking force that strong wind is resisted under captive.Therefore, it is necessary to specially design be equipped on mooring system and be
Balloon lift-off and recovery system are stayed, for the folding and unfolding of optoelectronic composite cable rope is monitored and controlled, meets tractive force, the traction speed of hawser
Degree and required braking force, ensure that captive balloon smoothly discharges and reclaimed.
Optoelectronic composite cable rope is aided with manpower and carries out folding and unfolding, controlling mechanism is not enough mainly by meter-measuring device metering at present
It is perfect.During cable laying, when actual cable laying length reaches setting cable laying length, stop cable laying manually；During take-up, when actual cable laying is grown
When degree is reduced to take-up desired value, stop take-up manually.Because the predetermined take-up terminal of hawser is artificially to estimate, along with scene
Some uncontrollable factors (such as strong wind), it is not in place to may result in captive balloon recovery.
From the foregoing, it is necessary to record the actual cable laying length of hawser and true in existing hawser recycling and control method
Determine the predetermined take-up terminal (next cable laying starting point) of hawser.
The method of the actual cable laying length of record hawser is that the metering dress of encoder is provided with traction wheel at present
Put, encoder records the rotating cycle of traction wheel, and meter-measuring device calculates the length of hawser process according to traction wheel diameter, i.e., real
Border cable laying length.When actual cable laying length reaches setting cable laying length, stop cable laying manually；When actual cable laying length is reduced to
During take-up desired value, stop take-up manually.But this method adds generation mistake by the predetermined take-up terminal artificially estimated
Risk.
Determining the method for predetermined take-up terminal at present has sleeve pipe label method, colour code method, laser induced method etc..Sleeve pipe mark
Knowledge method is during hawser produces, and sleeve pipe is installed additional in the appropriate position of hawser, so that it is determined that the terminal of hawser recovery.But
Hawser produced finish and use in when, dismounting difficulty it is big, sleeve pipe easily aggravates the abrasion of hawser epidermis in addition, also needs to increase
Protective layer, difficulty of processing are also big.Colour code method is to indicate take-up terminal by pasting the adhesive plaster of different colours on hawser,
This method is although economical and practical, but can not depart from manual operation, it is impossible to realizes Automated condtrol.Laser induced method is ten thousand
A set of laser sensor is filled to pulley, white adhesive plaster is pasted on hawser.When hawser passes through Universal pulley, white adhesive plaster reflection
Laser caused by laser, sensor receive optical signal, are converted into digital quantity by analog-digital converter, middle control PLC is received
After to signal halt instruction is sent to motor.Shortcoming is to need the start and stop of manual control laser sensor, it is impossible to realizes automation
Control, high is required to the weatherability of laser aid, cost is high.
