Embodiment
As shown in Figure 1, the hardware system of cutting vertical stream combine pace intelligence controlling device is made up of manauto switched system, sensor-based system, controller, executive system, liquid crystal display and automatic alarm system.
Sensor-based system is formed by being installed on the sensor of cutting each monitoring position on the vertical stream combine, comprise the Hall speed probe that is installed in cut flow roller, vertical stream roller, defeated grain screw feeder and the driving wheel rotating shaft, be installed on feed quantity sensor and the loss amount sensor that is installed on delivery chute in the rotating shaft of ceding of Taiwan screw feeder.The input of the output termination controller of sensor-based system.Controller inside is comprising implementation controller and display controller, the output termination liquid crystal display systems of display controller, liquid crystal display systems has state to show and sound and light of alarm, the input of the output termination proportioning valve amplifier 2 of implementation controller can carry out data communication between implementation controller and the display controller.The output of proportioning valve amplifier 2 inserts the free end of double-point double-throw switch 3, the common port of double-point double-throw switch 3 links to each other with the speed control valve 4 of cutting vertical stream combine, the free termination electric control handle 1 of another of double-point double-throw switch 3 is realized automanual switching by double-point double-throw switch 3.Manually control is by electric control handle 1 direct control rate control valve 4 as shown in Figure 3, and control drives proportioning valve amplifier 2 control rate control valves 4 by the implementation controller output voltage automatically.Speed control valve 4 is the ratio two-way valve, according to the circulating direction and the flow size of sense of current and big or small control valve.When manually controlling, double-point double-throw switch 3 is communicated with speed control valve 4 with electric control handle 1.Electric control handle 1 is electric ratio output, no-voltage output when handle places meta, and pushing ratio output forward voltage before handle is when the handle post-tensioning is exported backward voltage in proportion, by the output voltage control rate control valve 4 of handle.When controlling automatically, double-point double-throw switch 3 is communicated with speed control coil two ends with proportioning valve amplifier 2.This moment, handle lost efficacy, and cut the speed of vertical stream combine and was controlled by controller fully.The function of proportioning valve amplifier 2 be with the voltage linear of controller output be converted into current drives speed control valve 4, must demarcate it before use.Regulate output current by the MIN knob, when making controller Comparative Examples valve amplifier 2 input minimum voltage values, proportioning valve amplifier 2 output currents are 0; Regulate output current by the MAX knob, when making controller Comparative Examples valve amplifier 2 input maximum voltage value, proportioning valve amplifier 2 output currents just in time can make the pace maximum of cutting vertical stream combine.After proportioning valve amplifier 2 was adjusted and finished, the magnitude of voltage that only needs change input VI was the pace that controlled is cut vertical stream combine.The magnitude of voltage of input VI is produced by the DAC module in the implementation controller.
As shown in Figure 4, of the present utility model cutting indulged stream combine intelligence control method, and its concrete steps are:
Module parameter in step 1, the setting controller, and start-up control device.Module parameter comprises threshold value of warning, alarm threshold value and the weight of monitoring points such as feed quantity, cut flow roller rotating speed, vertical stream roller rotating speed, defeated grain screw feeder rotating speed, loss amount, and normally travel velocity amplitude, deceleration value, acceleration figure etc.
Gray prediction module flow process as shown in Figure 5, the original ordered series of numbers of cut flow roller rotating speed is obtained by control system sampling, its length is general
〉=4, do not lose accuracy again in order to simplify calculating, among the design
=4.The each sampling of control system obtains the cut flow roller rotating speed
, can get original number and classify as:
The sampling period of system is 0.5 second, and cereal is about 1.5 seconds through the time that inclined transporter arrives cut flow roller, and the response time of hydraulic continuously variable transmission is about 1 second, so the step number of selected prediction
=5.
Because drum rotation speed all be on the occasion of, do not need regularization to handle.Original ordered series of numbers is carried out accumulation process, and then the generation ordered series of numbers that obtains adding up:

Output valve and coupling weight for vertical stream roller fuzzy control model;
Step 4, controller are always exported by system
Select the control corresponding method.Vertical stream combine feed quantity is excessive when cutting, doing stopping alarm when any one rapid variation surpasses the setting boundary in cut flow roller rotating speed, vertical stream roller rotating speed or the defeated grain screw feeder rotating speed handles, this moment buzzer warning, LCD shows the trouble point, and the DAC output of implementation controller is reduced to 0 and made and cut vertical stream combine and quit work; Increase when cutting vertical stream combine feed quantity, loss amount increases, any one drops to 90% o'clock of optimum speed in cut flow roller rotating speed, vertical stream roller rotating speed or the defeated grain screw feeder rotating speed, doing slows down observes the adjustment operation, and employing reduces pace and reduces feed quantity, reduces live load, reach the minimizing rate of breakdown, LCD demonstrates the monitoring point that is lower than early warning value, and the DAC output voltage of implementation controller is pressed setting value and reduced, and makes to cut the reduction of vertical stream combine travel speed; When feed quantity, the stable not break bounds of loss amount, cut flow roller rotating speed, vertical stream roller rotating speed or defeated grain screw feeder rotating speed are all just often, in time increase pace, increase work efficiency, LCD shows each monitoring point duty, the DAC output voltage of implementation controller is pressed setting value and is raise, and makes to cut the lifting of vertical stream combine travel speed; When feed quantity, threshing cylinder, defeated grain screw feeder all are operated in optimum Working, control system did not keep present speed when loss amount exceeded standard, make unit be operated in optimum state, LCD shows each monitoring point duty, and the DAC output voltage of implementation controller keeps.
Step 5, judge whether manually to control, if enter manual control, then cut vertical stream combine pace Based Intelligent Control and finish, display still shows its duty.If do not enter manual control, then return step 2, proceed Based Intelligent Control.
