Abstract
An emergency stop system for an automation and motion control system enables an operator to connect a portable, handheld control device to the automation and motion control device anywhere in the system and provide a “stop” command to the emergency stop system.
Claims20
An automation and motion control system to control a plurality of theatrical objects, the control system comprising:
- a plurality of nodes in communication with each other over a real time network, each node of the plurality of nodes comprising a microprocessor and a memory device;
- a safety controller connected to one node of the plurality of nodes, the safety controller being operable to implement an emergency stop system;
- a control device, the control device comprising a connector to enable the control device to connect to a node of the plurality of nodes, the control device communicating with the safety controller over the real time network in response to being connected to the node of the plurality of nodes, the control device being operable to issue emergency stop commands to the safety controller once connected to the node of the plurality of nodes;
- and
- the connector being configured to enable the control device to be disconnected from a first node of the plurality of nodes and connected to a second node of the plurality of nodes at a different location from the first node.

An emergency stop control device for an automation and motion control system, the control device comprising:
- a housing having a predetermined size to permit an operator to carry and hold the housing;
- a microprocessor and a memory device positioned inside the housing;
- a connector extending from the housing to connect to a node of the automation and motion control system;
- a stop control button located on the outer surface of the housing, the stop control button being operable to issue an emergency stop command to a safety controller of the automation and motion control system in response to being connected to the node and the stop control button being activated;
- and
- the connector being configured to enable the control device to be disconnected from the node and connected to another node of the automation and motion control system at a different location.
3 more elements
A computer implemented method of using an emergency stop control device with an automation and motion control system, the method comprising:
- determining whether an emergency stop control device has been connected to an automation and motion control system;
- notifying a safety controller of the automation and motion control system that the emergency stop control device has been connected;
- receiving acknowledgement from the safety controller at the connected emergency stop control device;
- determining whether a control button on the emergency stop control device has been activated;
- and
- providing the safety controller with a command from the emergency stop control device in response to a determination that the control button on the emergency stop control device has been activated.
