[0029] Control mode 1 requires one activation signal and one voltage signal with a certain voltage value. The activation signal is connected before the voltage signal and then disconnected after the voltage signal: the bodywork power-on signal is connected to the timing signal a5, and the bodywork working signal is connected to the timing signal b6. Adjust the resistance value of the variable resistor R3 to make the voltage signal b8 the required size. When the bodywork is ready to work, power on first, and the power-on signal of the bodywork will be energized. Electricity, voltage signal b8 is output to realize engine speed control; bodywork stops, voltage signal b8 stops output, engine speed resumes, power is cut off after the operation is completed, relay KA1 loses power, and the activation signal is cancelled.
[0030] Control mode 2 requires one activation signal and two voltage signals whose voltage values are in a linear relationship: the timing signals a5 and b6 are c...

The invention relates to a chassis engine rotating speed control device and a control method. The chassis engine rotating speed control device comprises a power supply input port, a voltage division circuit, a signal output port and a circuit switching module, and the power supply input port receives a power supply voltage signal provided by a chassis; the voltage division circuit divides a voltage signal received by the power supply input port into a voltage signal required by an engine by adjusting a variable resistor, the voltage signal is output to the circuit switching module through the signal output port, and the circuit switching module controls on-off of a circuit through a manual control switch or a relay contact or a combination of the manual control switch and the relay contact; and the circuit switching module controls connection and disconnection of relay contacts according to the sequence of time sequence signals, outputs voltage signals according to the logic requirements of the engine, and transmits the voltage signals to an engine ECU. The chassis engine rotating speed control device has the beneficial effects that through mutual combination of different switching modes of the voltage division circuit module and the circuit switching module and cooperation of different time sequence signals, chassis engine rotating speed control of different control logics is achieved, and therefore the loading configuration unification is achieved.
Description
technical field [0001] The invention relates to a chassis engine speed control device and a control method, belonging to the technical field of engineering machinery. Background technique [0002] During the bodywork of special vehicles, the chassis engine is often required to provide a certain power speed. The engine speed control is gradually developing from traditional mechanical cable control and manual electronic control to automatic control. The engine speed control methods of different automobile manufacturers are different. Method 1: a voltage signal with a certain voltage value controls the engine speed. Different voltage values correspond to different speeds; Throttle control; Mode 3: On the basis of Mode 2, the activation signal and the speed voltage signal have certain timing requirements. For example, before the speed control, the activation signal needs to be given first, and when the speed control is over, the activation signal is disconnected after the need...
