Abstract
A hardware detection system according to one example includes a moveable contact body to contact a hardware item to be detected; an switching unit operatively coupled to the contact body; a reset device operatively coupled to the switching unit; and a control unit to receive a signal from the switching unit in response to a movement of the contact body and to issue a signal to the reset device in response to the signal from the switching unit.
Claims20
A hardware detection system, including
- a moveable contact body to contact a hardware item (HW) to be detected;
- a switching unit operatively coupled to the contact body;
- a reset device operatively coupled to the switching unit;
- and
- a control unit to receive a signal from the switching unit in response to a movement of the contact body and to issue a signal to the reset device in response to the signal from the switching unit.
A method of detecting hardware replacement in an electromechanical system, the system comprising a switching unit operatively coupled to a moveable contact body that is moveable into physical contact with a hardware item, the method comprising:
- biasing the moveable contract body toward physical contact with the hardware item;
- detecting whether the switching unit outputs a first signal and deciding, based on detection of the first signal, that the moveable contact body is in physical contact with the hardware item demonstrating tha the hardware item is present in the electromechanical system since a previous signal detection;
- detecting whether the switching unit outputs a second signal based on movement of the moveable contact body and deciding, based on the second signal, that the hardware item has been removed or replaced since a previous signal detection;
- and
- if the second signal is detected, resetting the switching unit.
An electromechanical equipment, including a number of replaceable hardware items, and further including
- a moveable contact body to contact one of the hardware items (HW);
- a switching unit operatively coupled to the contact body;
- a control unit to receive a signal from the switching unit in response to a movement of the contact body;
- wherein the control unit, on start up of the electromechanical equipment, detects a state of the switching unit based on the signal and determines whether hardware item has been replaced based on the detection result and, if replacement of the hardware item has been detected, issues a signal to reset the switching unit.
