Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, an example (hereinafter referred to as "this example") of detecting the relocation of the device by detecting the acceleration generated in the device by applying the relocation detection unit 1 installed to the device will be described. .

[0029] figure 1 is a block diagram showing an example of the internal configuration of the displacement detection unit 1 .

[0030] The displacement detection unit 1 having an acceleration sensor 5 having one or more axes is mounted to a device (not shown in the figure). Typically, a three-axis acceleration sensor for detecting acceleration on three axes is used as the acceleration sensor 5 .

[0031] The displacement detection unit 1 includes a battery (secondary battery) 3 and a charging circuit 2 for charging the battery 3, so that the displacement detection unit 1 can continue to function even when the powe...

Abstract

The invention relates to a displacement detection method and a displacement detection unit. The displacement detection unit includes: an acceleration sensor adapted to detect the acceleration generated in the device; an operation unit adapted to obtain a first calculation value by performing N-order integration on the detection value of the acceleration sensor at a predetermined timing, where N is a predetermined is a positive integer; a correcting section adapted to obtain a second calculated value by adding or subtracting a specific value to the first calculated value at a predetermined timing; The detection unit that detects that the device has been displaced when the set reference value is set.

Description

technical field [0001] The present invention relates to a displacement detection and control method of equipment, a displacement detection and control unit of equipment, preferably for detecting displacement of equipment such as machine tools (hereinafter referred to as "equipment"). Background technique [0002] As goods that can be used to develop weapons of mass destruction, etc., equipment with high precision and / or high performance is strictly controlled so that it is not exported illegally. However, once a device is exported overseas, it is difficult to prevent the device from being displaced by a third party to a country to which the device is not permitted to be exported. Thus, a mechanism is provided that, if a device is displaced from its mounting position without permission, detects this displacement, and prohibits the device from being operated again. [0003] In order to detect the displacement of the device, a method of detecting the magnitude of vibration due...
