Fig. 2 is schematic circuit diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of diesel-hydraulic locomotive constant-speed control device, is made up of gearshift select switch, control circuit, the proximity switch being positioned at transmission gearbox torque converter output shaft, the first constant speed select switch of interlock and the second constant speed select switch; The respective input of described control circuit connects the corresponding output end of described gearshift select switch, the first constant speed select switch, proximity switch respectively, its mouth connects the input end of described second constant speed select switch, and the input end of described first constant speed select switch connects the corresponding output end of described gearshift select switch.
Described gearshift select switch comprises automatic catch gating switch, manual I gear gating switch, manual II grade of gating switch; First and second constant speed select switches all have constant speed mode and normal mode two kinds of mode of operations.
Described control circuit comprises Programmable Logic Controller.
As shown in Figure 2, described first constant speed select switch and the second constant speed select switch are 7SAS, and described gearshift select switch is STS, and described Programmable Logic Controller is FX2-80MT-D, and described proximity switch is 2SQ; The X1 pin of Programmable Logic Controller described in the output termination of described proximity switch 2SQ; First to the 3rd input termination DC24V-power supply of described gearshift select switch, the first to the 3rd mouth connects the first input end of described constant speed select switch, X10 and the X11 pin of Programmable Logic Controller respectively; Second of described first constant speed select switch connects DC24V-power supply to four-input terminal, and its first to the 3rd mouth connects X7, X17 and X10 pin of described Programmable Logic Controller respectively; The Y20 pin of described Programmable Logic Controller connects the input end of described second constant speed select switch; The mouth of described second constant speed select switch connects self shifter I grade of electrically-controlled valve of described diesel-hydraulic locomotive through drive amplification plate.
Described constant speed select switch is heavily connection temperature selector switch reserved on locomotive console.
Described heavy temperature selector switch is LW5-16D0723/3.
The present embodiment is for GK1C type locomotive structural control schematic circuit diagram.
The X1 pin of PLC is high-speed pulse input end, connects the proximity switch 2SQ being positioned at torque converter output shaft.PLC compares the X1 impulse rate and the frequency preset that gather from 2SQ by ZCP instruction, control the output of locomotive forward direction or backward manual I grade of signal, gear shifting signal, through the action of amplification board, electropneumatic valve control hydraulic transmission gear box main control valve, realizes locomotive Loading Control.
The X7 pin of PLC is that input end is selected in self shifter, and X10 pin is manual I gear mouth, and X11 pin is manual II gear mouth; Self shifter exports and indirectly controls charge control cock, and manual I gear exports and indirectly controls change speed gear box main valve.
