The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of air supporting of chamber structure more than single barrel and sinking construction automatic control device, be characterized in: comprise the control platform that is arranged on staving top, on control platform, control system regulator cubicle is installed, tiltmeter and some GPS locating devices, in control system regulator cubicle, be provided with PLC control system, PLC control system is connected with monitoring staving sink-float and the analog module tilting and the analog input module of controlling staving sink-float and tilting, tiltmeter and GPS locating device join by connecting line and analog module, on the intake and exhaust pipeline of each bin of staving, vacuum pressure sensor is installed, on the discharge pipe line of each bin of staving, solenoid valve is installed, vacuum pressure sensor is connected with analog input module by connection line with solenoid valve.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, is provided with the host computer being connected with PLC automatic control system on control system regulator cubicle.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described GPS locating device is provided with four.
Compared with prior art, the utility model tiltmeter and GPS locating device join by connecting line and PLC Control system simulation module, vacuum pressure sensor is connected with the analog input module of PLC control system by connection line with solenoid valve, measure the angle of inclination of staving and the sink-float of staving, measurement result through RS485 communication interface real-time Transmission to PLC control system, then the height of the attitude to staving and rise and fall is controlled accurately, operating automation degree is higher, can effectively ensure construction quality.
Brief description of the drawings
Fig. 1 is control system connection layout of the present utility model.
Embodiment
A kind of air supporting of chamber structure more than single barrel and sinking construction automatic control device, comprise the control platform 2 that is arranged on staving 1 top, on control platform 2, control system regulator cubicle 5 is installed, tiltmeter 4 and some GPS locating devices 3, in control system regulator cubicle 5, be provided with PLC control system 7, PLC control system 7 is connected with monitoring staving sink-float and the analog module tilting and the analog input module of controlling staving sink-float and tilting, tiltmeter 4 and GPS locating device 3 join by connecting line and analog module, on the intake and exhaust pipeline of each bin of staving, vacuum pressure sensor is installed, on the discharge pipe line of each bin of staving, solenoid valve is installed, vacuum pressure sensor is connected with analog input module by connection line with solenoid valve.On control system regulator cubicle, be provided with the host computer 6 being connected with PLC automatic control system; Described GPS locating device is provided with four.
In the staving inflation transportation by driving stage, in many bins of staving 1 inside, be all filled with compressive charge, make staving 1 float on the water surface, adjust the aeration quantity in staving, make the underwater penetration of staving reach the requirement that meets towage stability.Therefore first PLC control system 7 will have the attitude of pair staving 1 to monitor, according to the data of monitoring attitude, calculate fast also FEEDBACK CONTROL topworks and carry out inflation/deflation adjusting, ensure the attitude stability of staving 1; Certainly sinking the stage, PLC control system 7 not only has attitude monitoring function, also must have absolute altitude monitoring function, and the fall rate that can calculate according to attitude, absolute altitude and absolute altitude is sunk and attitude adjustment control.Discharge and utilize dredge pump to draw water by the interior gas of staving 1, if be adjusted to horizontality by different separation air capacities and pump-out when run-off the straight in the speed of sinking by exhaust and the speed control of drawing water, sinking process simultaneously, until the water body in each staving all occurs that mud, staving reach designed elevation, the sinking of bucket body structure installs.
Described GPS locating device 3 is provided with four and is all connected to PLC control system 7 by RS232 port output warp, dimension signal, and PLC control system 7 judges according to the Z direction signal of GPS locating device output the situation that member changes, for attitude control provides foundation.Simultaneous computer reads GPS locating device signal and by coordinate conversion software, calculates the coordinate of member under engineering coordinate system, shows on computers.Separately be equipped with tiltmeter directly to link the analog module of PLC control system, by the CPU of PLC, it is carried out to scan round and carry out attitude control, therefore the Redundant Control strategy that this cover control system adopts, adopt two cover error correct systems carry out attitude and sink to controlling according to the preferential observing and controlling of predefined control, ensured the reliability and stability of control system.
At intake and exhaust pipeline, vacuum pressure sensor is installed, solenoid valve is installed on discharge pipe line.PLC control system adds master system, rise, inflate in staving air supporting in the process of transportation by driving, deadweight sinking and negative pressure sinking, taking staving degree of tilt and engineering absolute altitude as controlling target, calculate rear FEEDBACK CONTROL solenoid valve or dredge pump by automatic deviation correction program, adjust transportation by driving attitude and the positioning sinking attitude of staving.Vacuum pressure sensor is measured the air pressure in pipeline, directly links the analog input module of PLC control system, after PLC calculates, on host computer interface, shows.Host computer and PLC adopt the communication modes of RS485, and by the demonstration of host computer attitude in motion process to field equipment state and member, the alarm that system is produced, for site operation personnel provides operation reference.This utility model control accuracy is high, the angle of inclination of staving and the height of staving are measured by GPS locating device and tiltmeter, measurement result through RS485 communication interface real-time Transmission to PLC control system, attitude to staving and the height of rise and fall are controlled accurately, operating automation degree is higher, can effectively ensure construction quality.
