Brief description of the drawings
Fig. 1 is operation principle block diagram of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of multi-functional crawler crane multimode cooperative control system, complete machine electrical system mainly include
Expansible multimode combines type controller, touch screen displays, angular transducer, mode selection switch, pulling force sensor, pressure
Sensor, encoder, proximity switch, Engine ECU system；Such a control technology is mainly complete machine in construction, angle sensor
Device gathers arm support change angle, pulling force sensor collection complete machine lift heavy amount, and mode selection switch selects the current desired construction wanted
It is theoretical by fuzzy-adaptation PID control theory, multimode Collaborative Control in the unlike signals such as pattern input multimode combination type controller
Calculate the operational data of current hosts, monitor current working condition.
Such a control system can also realize efficient, the Energy Saving Control of engine：Controller is read by CAN technology
Start the engine parameter current in ECU, such as rotating speed, water temperature, engine oil pressure, DTC parameter, by gathering pump and valve
Pressure judges whether present load power output matches with engine output under the current rotating speed of engine, in time adjust pump and
The discharge capacity of valve, avoid because loading increase suddenly, bearing power is more than engine output and causes engine misses problem.Together
When this control system can also realize under vehicle immunization with gD DNA vaccine, realize that engine speed is minimum, save oil consumption, when main frame make
Engine speed raises automatically when industry detects load, reaches the speed of construction needs.
In view of safety factor, this utility model patent has also incorporated emergency flight control system, increases emergency loop in vehicle,
In the case of it can not realize normal construction because of main sensors, controller failure in main frame operation process, by system
Emergency loop is switched to, ensures the completion of a cycle operation, operating efficiency is improved, avoids failure.
In construction, angular transducer collection arm support change angle, pulling force sensor collection complete machine lift heavy amount, model selection
Switch is selected in the unlike signals such as the current desired Construction Mode wanted input multimode combination type controller, passes through fuzzy control
The working condition that system is theoretical, multimode Collaborative Control theoretical calculation goes out the operational data of current hosts, monitoring is current, passes through calculating
