When screw 1 and screw 2 are fixed in device housings and tighten, screw 1 and screw 2 and contact plate electrically conducting, nut 1 and nut 2 and contact plate are at a distance of a segment distance.
Described resistance R
1And resistance R
2, be used for and nut 1 and nut 2 difference electrically conductings.
Described contact plate is arranged on device interior, is used in screw during in device housings and the screw electrically conducting.Simultaneously characteristics such as resemblance such as described contact plate shape, size and material are not limited to a kind ofly, are good can reach the conducting electric current effect that needs.
(2) be resistance R
1, resistance R
2Certain voltage is provided.
Described resistance R
1Voltage be U
2, R
2Voltage be U
3, described U
2And U
3Can be the supply voltage of device interior, also can be the voltage that draw in other place of device interior.
(3) disassembling section of screw causes the variation of voltage on the nut of screw correspondence.
Described screw is equivalent to switch, when screw 1 and screw 2 are tightened fixedly on equipment, and screw 1, screw 2, nut 1 and nut 2 and contact plate electrically conducting.The magnitude of voltage that exist on nut 1 and the nut 2 this moment equates to be U
4, this magnitude of voltage U
4By described resistance R
1, resistance R
2And the magnitude of voltage U that upward exists
2, U
3Common decision.
When screw 1 was dismantled on by slave unit, screw 1, nut 1 disconnected with the contact plate electrically conducting, and the voltage that exist on the nut 1 this moment is U
2
When screw 2 was dismantled on by slave unit, screw 2, nut 2 disconnected with the contact plate electrically conducting, and screw 1, nut 1 and contact plate electrically conducting, the voltage that exist on the nut 1 this moment is U
2
(4) change in voltage on detection and record nut 1 and the nut 2 is determined the number of times that screw is turned on.
Default counter initial condition is 0.The voltage that detects on the nut 1 is U
4The time, illustrating that screw 1, screw 2 all are tightened, the counter that the machine number of times torn open in record adds 0; The voltage that detects on the nut 1 is U
