Abstract (en)

[origin: EP0911775A2] The method involves passing sensor data and data identifying the peripheral elements from peripheral elements (1) to a central station (2), which controls hazard counter measures in response to the received data. Data transfer follows a time frame defined by a system clock associated with the central station. The peripherals transfer routine system integrity signals to the central station in an associated sensor time slot (10). These are acknowledged with a signal used for synchronization. A peripheral waiting to transmit evaluates the traffic between the other peripherals and the central station on receiving the acknowledgment, then transmits its sensor data.
