The method of a kind of quick adjustment fire fighting truck hydraulic giant water yield and discharge pressure may further comprise the steps:
(1) controller, fire pump being set on fire fighting truck imports and exports pressure sensor, flow sensor is set; (2) setting controller control parameter; (3) sensor signal input controller; (4) according to the controller setup parameter, regulate the size of engine throttle automatically, regulate engine speed and exit of pump pressure and reach goal-selling.Described control parameter comprises exit of pump goal pressure, engine target rotating speed, idling.
Controller circuitry block diagram such as Fig. 2, use 16 single-chip microcomputers of Fujitsu to be core, use the DC/DC module with the voltage that fire fighting truck accumulate pond provides be stabilized to 24V, 12V, 5V uses for interlock circuit, use 18200 to drive direct current generator, use 9313 as digital potentiometer, use CAN bus communication mode, pressure and flow sensor use the 4-20mA way of output, it is the 0-5V signal with the signal transition of sensor that filtering and amplifying circuit are arranged, and speed probe is pulse output.
Control panel as shown in Figure 3.Below four charactrons show in real time respectively: outlet pressure (0-3.000MPa), vacuum pressure (0-100KPa), rotating speed (0-4000r/min) and flow (0-1000L/s), the water yield (0-9999m3).
Controller has two kinds of duties: default and operation.The running status workflow is as follows:
(1) power on or default lamp goes out by manipulated key, enter in manual state: manually indicator lamp is bright, and other all indicator lamps go out.It is bright just to change indicator lamp when pressing positive turn key, and motor just changes, and decontrols button, is just changeing indicator lamp and is going out, and motor stops.The counter-rotating indicator lamp is bright when pressing reverse key, and button is decontroled in the motor counter-rotating, and the counter-rotating indicator lamp goes out, and motor stops.
(2) default indicator lamp goes out, push control key, enter voltage-controlled state, the goal pressure indicator lamp is bright: with current malleation measured value is pressure control desired value, when the malleation measured value is controlled desired value+malleation deviant greater than pressure, and the motor counter-rotating, the counter-rotating indicator lamp is bright, when the malleation measured value equaled less than the malleation desired value, motor stopped, and the counter-rotating indicator lamp goes out.When the malleation measured value less than malleation desired value-malleation deviant, motor just changes, it is bright just to change indicator lamp, when malleation measured value during more than or equal to desired value, motor stops, and is just changeing indicator lamp and is going out.When being in voltage-controlled state, pressing and increase key pressure control desired value and increase, press reduce key then pressure control desired value reduce.
(3) default indicator lamp goes out, press the speed control key, enter the speed control state, the rotating speed of target indicator lamp is bright: be the speed control desired value with the rotating speed measured value, when velocity measurement greater than speed target value+velocity shift value, motor counter-rotating, the counter-rotating indicator lamp is bright, when velocity measurement during smaller or equal to speed target value, motor stops, and the counter-rotating indicator lamp goes out.When velocity measurement less than speed target value-velocity shift value, motor just changes, it is bright just to change indicator lamp, when malleation measured value during more than or equal to speed target value, motor stops, and is just changeing indicator lamp and is going out.When being in the speed control state, pressing and increase key speed control desired value and increase, press reduce key then the speed control desired value reduce.
(4) press idling, motor counter-rotating equals less than setting idle speed value up to rotating speed, and the control method of stating the speed control state according to last speed is controlled at rotating speed and sets near the idling, and side-play amount is equal to the speed control side-play amount in (3) step.
(5) when the very fast value of rotating speed more than or equal to setting, perhaps outlet pressure is more than or equal to the extreme pressure value of setting, and motor can not tighten up again.
During preset state work, controller is being controlled motor according to the selection under the running status, and this moment, the function of button changed, and was used to be provided with running parameter.
When default indicator lamp does not work, press preset key, enter preset state, default lamp is bright, and the flow indicator lamp is bright, and the top charactron shows flow.By〉〉 key, top charactron indicator lamp according to flow, press partially, speed partially, idling, order very fast, extreme pressure light, by＜＜key then according to extreme pressure, very fast, idling, speed partially, press partially, the order of flow lights.Press partially, speed partially, idling, when indicator lamp very fast, extreme pressure is lighted, change the numerical value that malleation deviant, velocity shifts are planted value, idling desired value, limit velocity, limit malleation with increasing and reducing key, change need just can come into force by the acknowledgement key affirmation at every turn.When the flow indicator lamp is bright, presses increase or reduce key, flow value zero clearing.When default lamp is bright, press preset key, withdraw from preset state.
It is last with the start water yield when top charactron powers on for showing.Be in running status: show this start water consumption (as not zero clearing, then show value is that former water consumption adds this start water consumption) when manually moving, display speed desired value during speed control shows voltage-controlled desired value when voltage-controlled.Be in state when presetting: displaying contents shows flow, malleation deviant, velocity shift value, idling desired value, limit velocity, limit malleation according to the operation of the right keyboard, and topmost LED lamp is corresponding one by one with displaying contents.
Flow value each second accumulative total once and store EEROM into, when the numerical value of velocity bias, idling desired value, limit velocity, limit malleation is pressed acknowledgement key, be saved in EEROM.
Power switch uses the waterproof aviation plug to connect external component on the controller side.
The foregoing description only is a preference of the present invention, is not used for limiting the present invention, and all within principle of the present invention, any modification, variation, accommodation or the alternative made are all within protection scope of the present invention.
