Abstract
A radio-based heat detection pellet is provided. The pellet includes a thermal switch configured to provide a detection signal when exposed to a temperature greater than a predetermined threshold temperature. The pellet further includes a transmitter circuit connected to the thermal switch and configured to transmit an alarm signal to a remote location in response to receiving the detection signal.
Claims25
A radio-based heat detection pellet, comprising:
- a thermal switch configured to provide a detection signal when exposed to a temperature greater than a predetermined threshold temperature;
- and
- a transmitter circuit connected to the thermal switch and configured to transmit an alarm signal to a remote location in response to receiving the detection signal.
A method, comprising:
- providing a set of radio-based heat detection pellets, each having a thermal switch and a transmitter circuit connected to the thermal switch;
- configuring the thermal switch to provide a detection signal when exposed to a temperature greater than a predetermined threshold temperature;
- and
- configuring the transmitter circuit to transmit an alarm signal to a remote location in response to receiving the detection signal.
1 more element
A system, comprising:
- a plurality of radio-based heat detection pellets, each having a thermal switch configured to provide a detection signal when exposed to a temperature greater than a predetermined threshold temperature and having a transmitter circuit configured to transmit an alarm signal to a remote location in response to receiving the detection signal;
- and
- one or more monitoring stations, each having a receiver for receiving the alarm signal from any of the plurality of radio-based heat detection pellets.
