Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and with the installation process of this embodiment, the present embodiment is described.
1, in engine case, singlechip controller 8 is installed in appropriate location, and singlechip controller 8 is connected with vehicle-mounted 12v stabilized voltage supply 7, provides whole device required electric power by vehicle-mounted 12v stabilized voltage supply 7.
2, connect current detection circuit.Install the first electrode contact 1 additional on machine oil slide calliper rule 3 tops, the second electrode contact 6 is installed on engine casing 5, on machine oil slide calliper rule 3, install two insulator slide calliper rule anti-shake rings 2 additional; The first electrode contact 1 is connected with corresponding port on singlechip controller 8 respectively with the second electrode contact 6, and makes the first electrode contact 1 for current input terminal; The first electrode contact 1, machine oil slide calliper rule 3, machine oil 4, engine casing 5, the second electrode contact 6 the are in series current detection circuit of device.
3, connect warning circuit.In parallel with a yellow light LED lamp 9 again after a red LED lamp 10 is connected with loudspeaker 11, then this circuit is received to corresponding port on singlechip controller 8.The warning circuit of red LED lamp 10, loudspeaker 11, yellow light LED lamp 9 common constituent apparatus.Described yellow light LED lamp 9, red LED lamp 10, loudspeaker 11 are installed on panel board.
