Abstract
The present invention relates generally to a system and method of networking and interconnecting a large number of various types of sensors to a remote location in an efficient manner. Specifically, the invention utilizes a flexible, configurable, scalable and power-efficient sensor interface relay architecture to gather sensor data from various locations and then relay it to a remote location via the internet.
Claims15
A method of obtaining inputs from a plurality of sensor coupling ports, comprising the steps of:
- from a first processing unit, communicating a state change on a first common addressing signal coupled to each of a plurality of second processing units and uniquely addressing one of the plurality of second processing units on at least one additional addressing signal;
- communicating from the first processing unit to each of the plurality of second processing units a subsequent state change on a common enable signal line coupled to each of the plurality of second processing units;
- detecting the state change on the first common addressing signal, the unique addressing, and the subsequent state change on the common enable signal line in one of the plurality of second processing units;
- and
- communicating from the first processing unit to the one uniquely addressed second processing unit to receive an input to the first processing unit from the sensor coupling port.
