Monitoring system and method
First Claim
1. A medical monitoring system for monitoring of an area, the system comprising:
- a plurality of stationary sensors without time stamping capability, configured to sense events and comprising a wireless output signal broadcast capability for transmitting output signals from the stationary sensors by a wireless communication protocol;
gateway units for receiving the output signals of the stationary sensors, the gateway units connected to a wired backbone network and configured to transmit information relating to the output signals of the stationary sensors by a wired communication protocol on the wired backbone network; and
a base station connected to the wired backbone network, the base station configured to receive the information transmitted by the gateway units on the wired communication protocol and to time-stamp the events signaled by the stationary sensors,wherein the area comprises sub-areas, wherein a group of stationary sensors are assigned to each of the sub-areas and to a gateway unit directly receiving the output signals of the group of stationary sensors, and wherein the network topology of the stationary sensors, gateway units and base station provides each stationary sensor with substantially the same communication path length to the base station so that the base station time stamps the signaled events in sequence order.
