Emergency stop system for drill floor safety

An apparatus, comprising:

• a controller configured to be operably coupled to a series of safety relays, each safety relay being coupled to a machine from a plurality of machines associated with oil drilling on an oil rig and distributed on a drill rig floor,
• the controller being configured to receive a signal indicative of a potential collision between personnel on the drill rig floor and any machine from the plurality of machines that is coupled to the at least one of the safety relays that was activated, the signal indicative of the potential collision being based on (1) image analytics conducted on an image captured by an optical camera disposed to capture images of the drill rig floor, and/or (2) a positional sensor disposed at or near the drill rig floor to identify personnel within a predefined or virtual zone associated with any machine from the plurality of machines,
• the controller being configured to send, in response to the signal indicative of the potential collision, a signal to at least one of the safety relays from the series of safety relays to activate the at least one of the safety relays, thereby stopping motion of any machine from the plurality of machines that is coupled to the at least one of the safety relays that was activated.
