3 pins on two normally closed switch and 5 pins in safety switch S4 have electricity, and connect in safety switch S4 on normal open switch
4 pins without electricity；2 power loss of position sensor simultaneously, the relay K1 power loss that position sensor 2 controls, is connected with Engine ECU
The normally opened contact power loss of relay K1 disconnect, no longer give Engine ECU power supply, power supply is hair by 3 feet of safety switch S4
Motivation ECU, which provides power supply, to be continued to power, and engine works on.Press auxiliary functional switch S1 at this time, relay K3 obtain it is electric, often
Contact closure is opened, since the pin 4 of the safety switch S4 to power for miscellaneous function solenoid valve Y is without electricity, miscellaneous function solenoid valve Y
It is not turned on, miscellaneous function cannot still start.Manual start switch S2 is pressed again, connects the circuit parallel operation route L1, this
When miscellaneous function solenoid valve Y from the pin 5 of safety switch S4 it is electric, loose one's grip after 5 seconds, be mounted in miscellaneous function solenoid valve Y oil outlet
Pressure switch S3 be closed because there is pressure, electric loop is switched to parallel operation route L2 by parallel operation route L1, from
The pin 5 of safety switch S4 obtains electric maintenance miscellaneous function solenoid valve Y power supply.The circuit parallel operation route L2 is also passed by seat position
Sensor 2 controls, and position sensor 2 controls relay K1, relay K1 power loss after machine subordinate vehicle, and the normally-closed contact of relay K1 obtains
Electricity closure, obtains relay K2 electric, and the normally opened contact closure of relay K2 maintains parallel operation route L2 to obtain electric, keeps auxiliary
Function solenoid valve Y power supply, can control miscellaneous function.
The utility model provides a kind of method of controlling security and device, can be by judging still to get off in bridge operation
Operation is to make different judgements.It is whether in place by general common photoelectricity switch detection operation machine hand, it is convenient to use again.
It uses two common position switch as safety switch, allows hand over electric wiring when two kinds of work.Pass through the above sensor
Along with common relay realizes two layers of protection, it can be ensured that machine hand leaves the safety operation of driver's cabin.The utility model is real
It is now simple, safely and effectively.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
