Description
Technical field
The utility model relates to a kind of teaching experimental base, is specifically related to a kind of automotive electronic control system system experimental, is used to demonstrate the engine operation process.
Background technology
Petrol engine is that kinetic energy drives automobile with the Conversion of energy of gasoline, and the simplest way is by obtaining kinetic energy in the engine interior burns gasoline.The engine of automobile generally all adopts 4 strokes, is respectively: air inlet, compression, burning, exhaust, finish this 4 processes, and engine is finished one-period (2 circle).Its groundwork process is: 1. piston begins at the top, inlet open, and piston down moves, and sucks fuel-air mixture; 2. piston moves toward the top and compresses fuel-air mixture, makes blast that power more be arranged; 3. when the piston arrives top, spark plug is emitted spark and is given me a little the fuel vapor combination gas, and blast makes piston move downward once more; 4. bottom the piston arrives, vent valve is opened, and piston up moves, and tail gas is discharged by gas outlet from cylinder.Piston is linked by a piston rod and bent axle, and the straight reciprocating motion of piston rod finally is converted into rotation by bent axle, could drive doughnut like this and rotate.
In the motion process of above-mentioned motor car engine, air inlet, air outlet valve are opened in due course respectively and are sucked fuel-air mixture and discharge tail gas, when compression and burning, these two valves all cut out, guarantee the sealing of firing chamber, thereby the to-and-fro movement of piston is to finish in the chamber of sealing.Yet just this can't see the mode of motion of piston clearly, the student can't have understanding intuitively when teaching, receives some CRANK PULSES by experiment on the platform and is presented on some display devices, as oscillograph, Displaying Meter etc.If will observe the engine interior working order intuitively, just engine must be dissected come (as dissecting engine),, can only drive with manual mode usually just so so can't allow normal working of engine, therefore there is not the sense of reality, the effect when not reaching the motor car engine normal operation.
Summary of the invention
The utility model purpose provides a kind of automotive electronic control system system experimental, but use the state of this experiment table simulated engine proper motion, and the body of dissecting can allow the student see the mode of motion of each parts of engine intuitively clearly, improves the quality of teaching greatly and efficient.
For achieving the above object, the technical solution adopted in the utility model is: a kind of automotive electronic control system system experimental, comprise an experiment table, this experiment table is mainly by engine electric-controlled unit, the signal Processing analogue unit, driving power and display unit are formed, control described signal Processing analogue unit by described engine electric-controlled unit, and output signal to described display unit by this signal Processing analogue unit, comprise that one dissects engine and driver element, each sensor signal output terminal on the described dissection engine is connected with described signal Processing analogue unit, and the execution signal of this signal Processing analogue unit output inputs to respectively on the executive component corresponding on the described dissection engine; The described dissection engine of described drive unit drives, the control end of this driver element is connected with the control signal output ends of described signal Processing analogue unit.
In the technique scheme, described dissection engine is a prior art, it executive component that comprises has atomizer, ignition coil, IACV (Idle Air Control Valve), air throttle component or the like, this dissection engine passes through drive unit drives, this driver element can adopt variable-frequency motor etc. usually, dissecting the action of engine is sent by the air throttle component signal processing unit, execution signal controlling frequency converter after the processing unit processes, the power that provides by driver element and turning round, be arranged at the sensor of dissecting on the engine simultaneously real-time information is sent to signal Processing ECU, each parameter after the processing can be passed through the display unit instrument, the LED lamp dynamically shows. by by the signal Processing analogue unit and dissect between the engine and carry out signal, the exchange of sensor signal, make engine electric-controlled unit ECU can directly control the running of dissecting engine, export by the power of signal Processing analogue unit control drive unit simultaneously, thereby realize experiment table and dissect combining between the engine, the student can observe the course of work of engine interior by the unlimited place of dissecting, and the running speed of engine can be controlled by ECU (Electrical Control Unit) ECU, the rotary state when reaching the motor car engine operate as normal.
In the technique scheme, described driver element comprises reducer casing, motor and frequency converter, the control signal output ends of described signal Processing analogue unit is connected with described frequency converter, the control end of this frequency converter is connected with described motor, and the output terminal of motor drives described dissection engine through described reducer casing.Give frequency converter by the control signal that the signal Processing analogue unit sends, control rotating speed of motor, and then the rotating speed of control dissection engine can make the rotating speed of dissecting engine be low to moderate tens rev/mins, the signal of sensor can slowly change, and helps the student and observes, understands.
In the technique scheme, the working signal output terminal of described dissection engine is connected with described display unit.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, because experiment table ECU (Electrical Control Unit) of the present utility model combines with the dissection engine, send the execution signal to dissecting each executive component of engine by the signal Processing analogue unit, and provide power for dissecting engine by driver element, and the sensor on the dissection engine is sent to the signal Processing analogue unit with the various types of signal of collecting, by the analogue unit computing, promptly constitute ECU (Electrical Control Unit) to dissecting the control of engine, each executive component of dissection engine can normally be moved under the control of carrying out signal, and need not to be in the chamber of sealing, the student can observe the motion process of engine by dissecting the part of freely opening, and is convenient to understand;
2, by the Frequency Converter Control motor speed, and frequency converter can need control arbitrarily to dissect the rotating speed of engine by the control signal control of signal processing unit output thus according to the observation, and the signal of sensor can slowly change, and helps the student and observes, understands.
3, dissect the engine simulation run, ECU (Electrical Control Unit) is controlled, is tested dissecting engine, and both complementations can increase substantially efficiency of teaching.
