Abstract: A Remote Consensus Control System (RCCS) allows authorized users to operate a device at a distance with consensus logic. One or more users can remotely apply a locking command. The device will remain locked until the very last user consents to unlocking. Any application requiring unanimous consent could use a RCCS to drive a mechanical lock, status indication, or a digital control or indication signal. The signal can drive a human-machine interface (HMI) or send a permissive signal, message, or command to open or initiate, close or terminate, or otherwise modify the state of a system or process. The RCCS is comprised of a logic system residing in a networked computing system. The logic system receives instructions from users (via mobile, web or text message), and issues responses to the users and commands to a set of binary outputs for each RCCS field device.
