Safety system for flaying machine

A safety system (100) for a working machine (1) whereby an operator (7) is able to interact with said machine (1), and wherein the system (100) comprises:

• a transceiver unit (71) associated with said operator (7) and configured to transmit a presence signal (Tx) representing the presence of said operator (7) in proximity to said machine (1);
• a central processing unit (11), associated with said working machine (1), configured to receive said presence signal (Tx);
• at least one conductive glove (81), designed to be worn by said operator (7) in conditions of interaction of said operator (7) with said machine (1), comprising electrical conduction means (85, 84) configured to operate in:
• a first operative condition (I) representing an ordinary functioning of said machine (1), wherein said operator (7) is electrically isolated from said machine (1);
• a second operative condition (II) representing an alarm state of said machine (1), wherein said operator (7) is in a condition of electrical conduction with said machine (1);
• electrical connection means (82) configured to connect said transceiver unit (71) to said at least one conductive glove (81);
• characterized in that said transceiver unit (71) is configured to operate using radio frequency and
• wherein said central processing unit (11) comprises:
• a reception module (111) configured to receive said presence signal (Tx);
• a memory module (112) configured to contain a predefined structure of presence signals (Txi_0) representing different operators (7) authorized to operate said machine (1);
• a recognition module (113) configured to compare the current presence signal (Tx) with said predefined structure of presence signals (Txi_0) comprised in said memory module (112);
• an authorization module (114) configured to enable use of the machine (1) by said operator (7) if the current presence signal (Tx) is compatible with the predefined structure of signals Txi_0 comprised in said memory module (112);
• a first alarm module (115) configured to transmit an alarm signal (Sx1) to said safety system (100) so as to disable said machine (1) if said second operative condition (II) occurs for said operator (7) authorized by said authorization module.
