Abstract
The invention relates to a material taking rotation boundary judgment and control system and method for a bucket wheel machine. The system comprises a pressure sensor, a signal collection remote station and a single-machine controller. The pressure sensor is connected with the signal collection remote station through a signal cable, and the signal collection remote station is connected with the single-machine controller through a communication cable. The method comprises the steps that firstly, the internal pressure of a bucket wheel hydraulic pressure of a material taking machine is acquired by the pressure sensor; secondly, pressure data are acquired by the signal collection remote station and transmitted to the single-machine controller; and thirdly, the pressure data are converted by the single-machine controller into a pressure value, the pressure value is compared with a preset pressure value, and whether the actual material stacking boundary is achieved or not is judged. According to the material taking rotation boundary judgment and control system and method, the material taking machine can carry out unmanned automatic operation safely, accurately and efficiently, meanwhile, idle running of the material taking machine in the operation process is reduced, and the material taking efficiency is improved.
Description
Technical field
The present invention relates to bucket wheel machine feeding automation field, particularly relate to bucket wheel machine feeding revolution border and judge control
System and method processed.
Background technology
Along with improving constantly that harbour bulk cargo terminals production management level requires, efficient, automation, unmanned,
Intellectuality has become as harbour bulk cargo terminals production control system development trend.In bulk cargo terminals production process, from
Dynamic feeding and automatic stockpiling control operation and have played an important role.But, existing nobody automatically controls
The factors such as it is low that operation also creates feeding efficiency, and feeding boundary Control accuracy is low.Therefore, by reclaimer bucket
Wheel pressure monitoring automatic material taking be turned back to the control method on limit provide more accurately feeding border to site.Enter
And, improve the Accuracy and high efficiency of unmanned operation.
Summary of the invention
The present invention provides bucket wheel machine feeding revolution border to judge control system and method.
Bucket wheel machine feeding revolution border judges control system, including pressure sensor, signals collecting distant station and list
Machine controller, pressure sensor connects signals collecting distant station through signal cable, and signals collecting distant station is through communication
Cable connects unit controller；
Described pressure sensor is arranged on reclaimer bucket wheel hydraulic motor, and described signals collecting distant station is arranged on
On reclaimer cantilever, pressure sensor is for detecting the pressure data of reclaimer bucket wheel hydraulic motor, signals collecting
Distant station is used for obtaining pressure data, and pressure data sends to unit controller, and unit controller is by pressure
Data are converted into force value, contrast with force value set in advance, and be made whether to arrive actual windrow
The judgement on border.
Further, described pressure sensor is hydrostatic sensor.
Further, described unit controller is unit PLC.
Bucket wheel machine feeding revolution border judges control method, comprises the step of:
The first step: pressure sensor obtains reclaimer bucket wheel hydraulic motor internal pressure；
Second step: signals collecting distant station obtains pressure data, and pressure data sends to unit controller；
3rd step: pressure data is converted into force value by unit controller, with force value set in advance carry out right
Ratio, and be made whether to arrive the judgement on actual windrow border.
The invention has the beneficial effects as follows: the present invention by pressure sensor measure feedback data message, according to than
Example computing calculates actual pressure value, judges revolution with the force value real time contrast set corresponding to feeding instantaneous flow
Whether feeding arrives limit, and then makes that reclaimer is safe and accurate, carry out unmanned automatic job efficiently, reduces simultaneously
Idle stroke in reclaimer operation process, improves feeding efficiency.

Wherein: 1-pressure sensor；2-signal cable；3-signals collecting distant station；4-communication cable；5-
Unit controller；6-reclaimer bucket wheel hydraulic motor；7-reclaimer cantilever.
Fig. 2 is the operational flowchart of unit controller of the present invention.
Detailed description of the invention
It is described in detail referring to the drawings below with reference to embodiments of the invention.
Bucket wheel machine feeding revolution border judges control system, including pressure sensor 1, signals collecting distant station 3
With unit controller 5, pressure sensor 1 connects signals collecting distant station 3, signals collecting through signal cable 2
Distant station 3 connects unit controller 5 through communication cable 4；
Described pressure sensor 1 is arranged on reclaimer bucket wheel hydraulic motor 6, described signals collecting distant station 3
Being arranged on reclaimer cantilever 7, pressure sensor 1 is for detecting the number pressure of reclaimer bucket wheel hydraulic motor 6
According to, signals collecting distant station 3 is used for obtaining pressure data, and pressure data sends to unit controller 5,
Pressure data is converted into force value by unit controller 5, contrasts with force value set in advance, and makes
The most arrive the judgement on actual windrow border.
Further, described pressure sensor 1 is hydrostatic sensor.
Further, described unit controller 5 is unit PLC.
Bucket wheel machine feeding revolution border judges control method, comprises the step of:
The first step: pressure sensor 1 obtains reclaimer bucket wheel hydraulic motor 6 internal pressure；
Second step: signals collecting distant station 3 obtains pressure data, and pressure data sends to unit controller
5；
3rd step: pressure data is converted into force value by unit controller 5, is carried out with force value set in advance
Contrast, and be made whether to arrive the judgement on actual windrow border.
The computing flow process of unit controller 5 is as follows:
Return data according to pressure sensor and calculate reclaimer bucket wheel hydraulic motor internal pressure value, reclaimer bucket
Wheel hydraulic motor internal pressure value is set to A, presets force value corresponding to feeding amount and is set to B；According to currently
It is a that feeding floor height does the variable that inverse proportional operation draws, goes out by inverse proportional operation with the speed of gyration ratio of revolution feeding
Percentage be b；
If A is more than B*a%, and adds up to reach time T1 more than B*a%, now assert that bucket wheel is current the most
Start a cut through stockpile and start normal feeding；
On the premise of normal feeding, A is less than B*b%, if the time that accumulation is less than B*b% is not up to T2,
Recover again to the A state more than or equal to B*b%, it is judged that not arriving actual stockpile border, continuation is in logic
Middle supervision judges；Reach T2 when the accumulation time less than B*b%, i.e. determine that current reclaiming process has arrived reality
The border of stockpile.
Described bucket wheel machine feeding revolution border judges that control system and method can also detect feeding amount.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these
Improvements and modifications also should be regarded as protection scope of the present invention.
