Abstract
According to an aspect of the present invention, there is provided a method and apparatus for controlling access to a restricted area containing machinery. The method comprises receiving from a communications device a location identifier associated with said restricted area and a further identifier, verifying said location identifier and said further identifier, and controlling access to said restricted area based upon said verifying. Controlling access to said restricted area comprises providing a control signal to a controller associated with said restricted area. The controller is arranged to control said machinery in response to said control signal.
Claims18
A method of controlling access to a restricted area containing industrial machinery comprising the steps of:
- requesting access to said restricted area, wherein requesting access includes the steps of:
- receiving with a mobile communication device a location identifier from a stationary communication device associated with said restricted area;
- transmitting a first set of data including the location identifier associated with said restricted area and a further identifier associated with the mobile communication device to a remote processor;
- and
- verifying said location identifier and said further identifier at the remote processor;
- providing a first control signal to a controller associated with said restricted area from the remote processor based upon said verifying of said location identifier and said further identifier, said controller being arranged to control said industrial machinery to operate in a first mode in response to said first control signal;
- and
- restarting said industrial machinery, wherein restarting said industrial machinery includes the steps of:
- transmitting a second set of data including the location identifier associated with said restricted area and the further identifier associated with the mobile communication device to the remote processor;
- verifying that the further identifier transmitted in the second set of data comprises a match with the further identifier transmitted in the first set of data;
- and
- providing a second control signal to the controller associated with said restricted area from the remote processor based upon said verifying of further identifier from the first and second sets of data, said controller being arranged to control said machinery to operate in a second mode in response to said second control signal.

A system for controlling access to a restricted area comprising:
- a memory storing processor readable instructions;
- and
- a processor arranged to read and execute instructions stored in said memory;
- wherein said processor executes said readable instructions to
- receive a first set of data from a mobile communication device to request access to said restricted area, the first set of data including a location identifier associated with said restricted area and a further identifier, wherein the location identifier is previously transmitted to the mobile communication device from a stationary communication device associated with said restricted area;
- verify said location identifier and said further identifier;
- control access to said restricted area based upon said verifying, wherein access to said restricted area is controlled by a first control signal sent to a controller associated with said restricted area, said controller being arranged to control industrial machinery to operate in a first mode in response to said first control signal;
- receive a second set of data from the mobile communication device to restart said industrial machinery, the second set of data including the location identifier associated with said restricted area and the further identifier;
- verify that the further identifier transmitted in the second set of data comprises a match with the further identifier transmitted in the first set of data;
- and
- control access to said restricted area based upon said verifying, wherein access to said restricted area is controlled by a second control signal sent to the controller associated with said restricted area, said controller being arranged to control said industrial machinery to operate in a second mode in response to said second control signal.
8 more elements
A system for controlling access to a restricted area comprising:
- means for receiving from a mobile communication device a first set of data to request access to said restricted area, the first set of data including a location identifier associated with said restricted area and a further identifier, the location identifier previously transmitted to the mobile communication device from a stationary communication device;
- means for verifying said location identifier and said further identifier in the first set of data;
- means for controlling access to said restricted area and for operating industrial machinery within said restricted area in a first mode based upon said verifying;
- means for receiving from the mobile communication device a second set of data to restart the industrial machinery, the second set of data including the location identifier associated with said restricted area and the further identifier;
- means for verifying said further identifier from the first set of data matches said further identifier from the second set of data;
- and
- means for controlling access to said restricted area and for operating the industrial machinery within said restricted area in a second mode based upon said verifying that said further identifier from the first set of data matches said further identifier from the second set of data.
