A DISTRESS SIGNALING SYSTEM, A BODY AREA NETWORK FOR ENABLING A DISTRESS SIGNALING, A METHOD FOR SIGNALING A CONDITION OF A DISTRESS AND A VEHICLE ARRANGED WITH A DISTRESS SIGNALING SYSTEM

摘要

The invention relates to a distress signaling system, a body area network for enabling a distress signaling, a method for signaling a condition of a distress and a vehicle arranged with the distress signaling system. The distress signaling system 10 according to the invention comprises monitoring means 11 arranged in a vehicle in order to monitor a vital sign of a seated passenger by means of a sensor 12 arranged to measure a signal representative to said sign. The monitoring means 11 are preferably arranged to perform a continuous monitoring of the vital sign of the passenger and are further arranged to provide a corresponding signal to the front-end electronics 20 of the system 10 . The front-end electronics 20 is arranged to analyze the signal from the monitoring means 11 . For that purpose the front-end electronics 20 comprises a data processing means 21 arranged to process the measured signal in order to yield data representative to a condition of the passenger. The data processing means 21 comprises a preamplifier 22 , an analogue processing circuit 22 and an ADC unit 23 . The data processing means 21 forwards the corresponding data to the data analysis means 25 , arranged to analyze said data in order to yield a condition-related parameter. The determined condition-related parameter is written into a first look-up table 25 a. The data analysis means 25 is further arranged to compare said condition-related parameter to a preset valid parameter stored in a second look-up table 25 b. In case the data analysis means detects that the condition-related parameter exceeds a preset valid parameter, it generates a trigger signal to actuate the indicating means 26 . The indicating means 26 receives the trigger signal and generate a suitable feedback to the passenger, preferably by means of a suitable user-interface 27 . Additionally, the indicating means 26 can be arranged to control a vehicle control system 29 , in order to alter a cabin environment, or to actuate an alarming means of the vehicle, like an acoustic alarm and/or the emergency lights and/or to actuate an engine of the vehicle.
