Accompanying drawing explanation
Fig. 1 is this utility model theory diagram；
Detailed description of the invention
As it is shown in figure 1, a kind of intelligent control system for paving machine has a controller；Controller connects one and is used for realizing stepless-adjustment
The speed potentiometer of speed, controller connects an electronic compass for the direction that monitoring paver travels in real time, and controller connects
One direction setting button, controller connects one for gathering the left velocity sensor of paver left crawler belt travel speed, controller
Connecting a right velocity sensor being used for gathering paver right-hand track chiain travel speed, controller connects one and is used for detecting water tank temperature
Cooling-water temperature sensor, controller connects one for detecting the oil temperature sensor of tank temperature, and controller connects one and is used for detecting material
The level sensor of position information, controller connects one and is used for showing water temperature, oil temperature and the display of material position information, and controller is even
Connect one for the sound prompt device of voice message.Controller output control paver left and right driving pump flow left front enter ratio
Example electromagnetic valve, right advance proportional solenoid, left front enter proportional solenoid, right advance proportional solenoid.
In the present embodiment, controller uses PLC.Left velocity sensor and right velocity sensor all use Hall-type rotating speed to pass
Sensor, the corresponding inside being arranged on the left and right driving motors of paver.Speed potentiometer and electronic compass are arranged on paver and drive
Sail on the operating board of room, facilitate operated by personnel.
As a example by paver advances, specifically introduce its work process:
Left road speed sensors monitors paver left crawler belt travel speed v1 in real time, and right travel velocity sensor is supervised in real time
Surveying paver right-hand track chiain travel speed v2, electronic compass monitors the direction that paver travels in real time.Controller is according to speed current potential
The certain electric current of the deviation e1 output of setting value v that device is given and left crawler belt travel speed v1 control left front enter proportional solenoid,
Realizing the closed loop control to left crawler belt travel speed, its control algolithm uses PID to control.
Before operating paver, first adjust the direction of paver, when controller input port collects direction setting
During the twinkling signal that switch is pressed, electronic compass gather the direction of now paver traveling as paver travel direction
Setting value；When operating paver, correction value q of paver travel direction by the setting value of paver travel direction with adopt in real time
Paver travel direction data d1 of collection are subtracted each other and are obtained, repairing of setting value v that speed potentiometer is given and paver travel direction
Obtaining setting value r of right-hand track chiain speed on the occasion of q through fuzzy operation, controller is according to setting value r of right-hand track chiain speed and right shoe
Deviation e2 with travel speed v2 exports certain electric current and controls right advance proportional solenoid, it is achieved to right-hand track chiain travel speed
Closed loop control, its control algolithm is also adopted by PID control.
When correction value q of paver travel direction is 0, setting value r of right-hand track chiain speed is given equal to speed potentiometer
Setting value v, now both sides crawler belt travel speed control set-point should be consistent, it is not necessary to correction, it is only necessary to constant speed
Control；When correction value q of paver travel direction is more than 0, illustrates that paver travels toward right avertence, obtain after fuzzy operation
Setting value r of right-hand track chiain speed should be greater than setting value v that speed potentiometer provides, and to increase the speed that right-hand track chiain travels, reaches
Turn left correction purpose；In like manner, when correction value q of paver travel direction is less than 0, illustrate that paver travels toward left avertence, warp
Setting value r obtaining right-hand track chiain speed after crossing fuzzy operation should be less than setting value v that speed potentiometer provides, to reduce right-hand track chiain
The speed travelled, reaches the purpose rectified a deviation of turning right.
Paver fallback procedures controls similar with above-mentioned work process.
Water tank temperature, tank temperature and material position information is shown in real time, when water tank temperature, tank temperature, material on display
When position information reaches setting value, reminded by voice suitcase device.
The factors pair such as slipperiness on roads, pavement roughness, hydraulic system leakage can be preferably overcome by the use of native system
The impact of paver constant speed straight-line travelling, substantially increases the spreading quality on road surface.
