Description
Technical Field
The invention relates to a vehicle, in particular to a singlechip control device of the vehicle.
Background
Vehicles operating in an environment with flammable gases often employ pneumatic systems. For example, the pneumatic system of the trackless rubber-tyred vehicle with the explosion-proof diesel engine disclosed in chinese patent document CN205086691U (application No. 201520923719.2) completes the start of the diesel engine, the braking of the vehicle, the adjustment of the exhaust gas treatment, the control of the accelerator pedal, and the control of the horn through the pneumatic system. The air inlet of the air storage tank 1 of the trackless rubber-tyred vehicle pneumatic system of the explosion-proof diesel engine is connected with the air compressor 2 in the engine through a pipeline, generally speaking, the input shaft of the air compressor 2 in the engine is in transmission connection with the crankshaft of the engine, after the engine is started, the crankshaft of the engine drives the input shaft of the air compressor 2 to rotate, and the air compressor 2 can output pressure gas. As shown in fig. 4, in a pneumatic system in the prior art, a one-way valve 3 is generally connected to an air passage from an air outlet of an air compressor 2 to an air inlet of an air storage tank 1, the air outlet of the air compressor 2 is communicated with the air inlet of the one-way valve 3, and the air outlet of the one-way valve 3 is communicated with the air inlet of the air storage tank 1, so that pressure air output by the air compressor 2 can reach the air storage tank 1 through the one-way valve 3, and the air storage tank 1 conveys the pressure air to a pneumatic component needing to use the pressure air through an air pipe 5.
The single chip microcomputer control device of the vehicle in the prior art is shown in fig. 3 and comprises a single chip microcomputer 11, a power supply 12 and a power switch 13, wherein the power supply 12, the power switch 13 and the single chip microcomputer 11 are electrically connected in sequence to form a loop. When the vehicle is started, the driver manually closes the power switch 13, the power supply 12 can supply power to the singlechip 11 on the vehicle, and the singlechip 11 controls other components on the vehicle to act. In the vehicle singlechip control device in the prior art, after the vehicle is shut down, a driver needs to manually turn off the power switch 13, so that the power supply 12 does not supply power to the singlechip 11 any more. That is to say, the power switch 13 of the single chip microcomputer control device cannot be automatically switched off after the vehicle is shut down, so that the power supply 12 still supplies power to the single chip microcomputer 11 after a driver forgets to switch off the power switch 13 and leaves the vehicle after the vehicle is shut down, energy is wasted, the problem of power feeding of the power supply 12 is caused, and the next starting of the vehicle is influenced.
Disclosure of Invention
The invention aims to provide a singlechip control device of a vehicle, wherein a power supply does not supply power to a singlechip any more after the vehicle is shut down.
In order to achieve the purpose, the invention adopts the following technical scheme: a single chip microcomputer control device of a vehicle comprises a single chip microcomputer, a power supply and a power switch;
the pneumatic pressure switch is also included; the power supply, the power switch, the pneumatic pressure switch and the singlechip are electrically connected in sequence to form a loop; when the pneumatic pressure switch is used, the pneumatic control port K of the pneumatic pressure switch is connected to a gas channel from the gas outlet of the air compressor to the gas inlet of the one-way valve; when the pneumatic control port K of the pneumatic pressure switch is filled with pressure gas, the pneumatic pressure switch is closed.
The invention has the following positive effects: (1) the power supply, the power switch, the pneumatic pressure switch and the singlechip are sequentially and electrically connected to form a loop; when the pneumatic pressure switch is used, the pneumatic control port K of the pneumatic pressure switch is connected to a gas channel from the gas outlet of the air compressor to the gas inlet of the one-way valve; when the pneumatic control port K of the pneumatic pressure switch is communicated with pressure gas, the pneumatic pressure switch is closed, so that after the engine is flamed out, the air compressor cannot output the pressure gas, the pneumatic control port K of the pneumatic pressure switch cannot be communicated with the pressure gas, and the pneumatic pressure switch is in an off state. At this time, even if the power switch is in a closed state, the power supply cannot supply power to the singlechip because the pneumatic pressure switch is in an open state. The invention can realize that the power supply can not supply power to the singlechip any more after the vehicle is flamed out, so that the power supply can not supply power to the singlechip of the vehicle even if a driver forgets to turn off the power switch and leave the vehicle when the vehicle is flamed out, thereby not only saving energy, but also not causing the problem of power supply feed and not influencing the starting of the next vehicle.

The reference numbers in the above figures are as follows: the air compressor comprises an air storage tank 1, an air compressor 2, a one-way valve 3, an engine 4, an air pipe 5, a single chip microcomputer 11, a power supply 12, a power supply switch 13 and a pneumatic pressure switch 14.
Detailed Description
The invention is further described below with reference to the accompanying drawings and the examples given.
As shown in fig. 1, a single chip microcomputer control device of a vehicle includes a single chip microcomputer 11, a power supply 12 and a power switch 13;
also included is a pneumatic pressure switch 14; the pneumatic pressure switch 14 is an air pressure switch of the type LEFOO-LF10-1H 3. The power supply 12, the power switch 13, the pneumatic pressure switch 14 and the singlechip 11 are electrically connected in sequence to form a loop; as shown in fig. 2, when in use, the pneumatic control port K of the pneumatic pressure switch 14 is connected to the air passage from the air outlet of the air compressor 2 to the air inlet of the one-way valve 3; that is, the pneumatic control port K of the pneumatic pressure switch 14 communicates with the air passage from the air outlet of the air compressor 2 to the air inlet of the check valve 3. When the pneumatic control port K of the pneumatic pressure switch 14 is filled with pressure gas, the pneumatic pressure switch 14 is closed. When the pneumatic control port K of the pneumatic pressure switch 14 is not filled with pressure gas, the pneumatic pressure switch 14 is turned off.
As shown in fig. 1 and 2, the working principle of the present invention is as follows: when the vehicle is not flamed, namely the engine 4 is not flamed, the engine 4 is in a working state, the crankshaft of the engine 4 rotates, the input shaft of the air compressor 2 also rotates, the air compressor 2 outputs pressure gas, the pneumatic control port K of the pneumatic pressure switch 14 is communicated with the pressure gas, the pneumatic pressure switch 14 is communicated, the power switch 13 is manually communicated, the power supply 12 can supply power to the singlechip 11, and the singlechip 11 on the vehicle can normally work.
When the vehicle is flamed out, namely the engine 4 is flamed out, the crankshaft of the engine 4 does not rotate any more, the input shaft of the air compressor 2 does not rotate any more, the air compressor 2 cannot output pressure gas, the pneumatic control port K of the pneumatic pressure switch 14 cannot be communicated with the pressure gas, and the pneumatic pressure switch 14 is in a disconnected state. At this time, even if the power switch 13 is in the closed state (i.e., the driver forgets to turn off the power switch 13 when the vehicle is turned off), the power source 12 cannot supply power to the one-chip microcomputer 11 because the pneumatic pressure switch 14 is in the open state. The invention can realize that the power supply 12 can not supply power to the singlechip 11 any more after the vehicle is flamed out, so that the power supply 12 can not supply power to the singlechip 11 of the vehicle even if a driver forgets to turn off the power switch 13 and leave the vehicle when the vehicle is flamed out, thereby not only saving energy, but also not causing the problem of power feeding of the power supply 12 and not influencing the starting of the next vehicle.
