Specific embodiment
The deep-sea cable laying drum type cable laying machine of the utility model is specifically included that as shown in FIG. 1 to FIG. 2
Cable laying machine ontology, including drum machine；
Two are each equipped with the motor of transducer drive, are connected respectively by speed reducer and drive drum machine jointly；Two become
Frequency device is respectively to drive corresponding motor, respectively to drive two motors, passes through the common drive drum that is rigidly connected
Machine operating, realizes warm back-up, will not influence normal construction a frequency converter tripping grinder.Also, with shallow sea situation
Difference, under deep sea condition, due to the gravity of optical cable itself, actually frequency converter is in brake power generating shape during cloth cable
State, therefore two frequency converters are respectively configured with a 40Kw braking resistor.
GPS, to speed-position detection, wherein position data is used to calculate the routing length that construction ship is walked, speed data
For controlling drum machine revolving speed.GPS device is sent the longitude and latitude of current optical cable place of entry and current ship's speed with the frequency of 1Hz
To PLC.It is to be more suitable for long distance transmission that the RS232 interface that GPS device specifically can be used, which passes through Delta IFD8500 interface conversion,
The message length of RS485 interface, GPS is greater than 100 bytes, therefore completes data using the DVPSCM12 communication module of Delta
It receives and preliminary treatment works, then data are extracted from message according to NMEA protocol specification by PLC.The message used includes:
GPGGA message (wherein including latitude and longitude information), GPVTG message (wherein including ship's speed information).
Fathometer, to detect current cloth cable depth；
Optical cable tension sensor, to detect current optical cable tension.The tension of optical cable needs to monitor in real time, and ensures to be less than
Its tension that is broken, cable breakout otherwise occurs in the work progress of deep-sea will cause loss very serious.In control system
Force signal has two-way source: optical cable tension sensor and motor torque.Wherein, optical cable tension sensor is converted to optical cable tension
The signal of 4~20mA sends PLC to；In addition PLC reads the output torque of every motor by communication, joins further according to machine driving
It counts to estimate the tension of optical cable, available accurate motor torque under closed loop magnetic flux vector mode.
PLC, receiving the measured data of GPS, fathometer, optical cable tension detector, calculate current lay length and
Required cloth cable speed issues motor control signal to frequency converter, and keeps two frequency converters consistent to speed；Delta specifically can be used
The slim PLC of SV2 series carries out logic control, parsing GPS data etc..What SV2 and its expansion module used is all plug type end
Son, quick replacement when conveniently breaking down.
Industrial personal computer is connected with PLC, is monitored to entire control process, and carry out data deposits reading.It specifically can be used remote
Nearly each one group, wherein 1# industrial personal computer runs KingView software, for monitoring and controlling, in addition lays data (including each Route Area
Length, laying slack, the tension protection value etc. of section) it is all directly stored in 1# industrial personal computer, it is completed by Access database big
The typing and storage of amount laying data record operation conditions and generate report.2# industrial personal computer operation remote monitoring software is supervised in real time
The picture for controlling 1# industrial personal computer, can also remotely be controlled when necessary.
According to the complexity of landform, practice of construction route has often divided dozens of even a sections up to a hundred, Mei Gequ
Section will be arranged the data such as independent ship's speed, laying slack, tension protection value, the typing and storage of these huge data all by
Access database is completed, and using the database function of KingView software, the area being presently in is calculated automatically according to GPS data
Section, and each construction data corresponding to the section is passed into PLC.Configuration software is also at regular intervals by the fortune in construction
Row data preserve, and user may be selected to generate the statistical report form in the corresponding period.The data of record include GPS coordinate, ship
The information such as speed, current of electric, motor torque, optical cable tension.
Danfoss FC302 Series Frequency Converter can be used in the frequency converter, and cooperation MCO305 motion control card realizes closing for motor
Ring magnetic flux vector control, it is accurate to control motor operating, it is completed at the same time cable length computing function.Danfoss FC302 frequency converter
The problem of input voltage range is 380~500V ± 10%, can successfully manage voltage instability on ship；The 3C3 anticorrosion of standard configuration
Enhancing coating and 50 DEG C of highest of operation temperature improve reliability of the frequency converter under bad working environments.The long line that MCO305 is used
Driving encoder, has a good interference free performance, and frequency converter can detect automatically encoder whether break down with
Just it is handled in time.
And two motors need that load is made to be evenly distributed to every electricity as far as possible when dragging the same load by rigid connection
On machine, it is otherwise likely to occur laod unbalance, the even opposite situation of torque, this is especially apparent during acceleration and deceleration.
Only make sure that the revolving speed of two motors be unanimously it is inadequate, in order to solve this problem, using the speed of Danfoss frequency converter
Trim (fine speed adjustment) function.It is as shown in Figure 3:
The identical speed of two frequency converters and start stop signal are given by short message broadcast communication mode, to guarantee two
The speed preset of frequency converter is completely the same, while by the torque percentage of 1# frequency converter with the output of 4-20mA analog signals
To 2# frequency converter, open the speed trim function of 2# frequency converter, such 2# frequency converter will on the basis of bus speed is given,
It is superimposed a fine adjustment speed, and then the torque variation of dynamic " following " 1# frequency converter according to the loading condition of 1# frequency converter, with reality
It is now shared with the load of 1# frequency converter.
Typical deep-sea cable is formed by connecting by several different optical cables, is wanted with meeting the work of different water depth environment
It asks, structure such as Fig. 4:
The different optical cable of these types has just been connected according to design length after the completion of production.Thus while in system
Frequency converter works in velocity mode, but the lay length of optical cable also has to accurately control, if midway laying optical cable is excessive,
It may cause finally that log in section optical cable inadequate；If midway laying optical cable is very few, and may cause with more fragile deep-sea cable
It logs in.In several hundred or even thousands of kilometers, it is long generally to log in the double armor optical cable that section uses for the laying path length of deep-sea cable
Only several kilometers of degree, so the error of lay length will be within 1%, therefore MCO305 motion control card is installed additional for frequency converter and is come
The current location of motor is obtained, and is read by PLC by communication, it is long the optical cable laid can be calculated further according to mechanical parameter
Degree.
In conclusion the deep-sea cable laying drum type cable laying machine of the utility model, is selected using perfect parameter setting
The equipment that item and monitoring function ensure that runs smoothly efficiently, and the laying that several deep-sea cables are smoothly completed in trying out is applied
Any alarm or shutdown do not occur in work progress for work, and system stable operation always.Also very simple is easy for system debug,
Obtain client's favorable comment consistent with owner's.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
Variation, the modification of the upper embodiment will all be fallen in the Claims scope of the utility model.
