Abstract
Devices, systems, and techniques relating to steam trap monitoring are described. These include battery-less steam trap monitors that run on power harvested from their environments, systems for acquiring steam trap monitor data for the traps in a facility or across multiple facilities, and techniques for processing steam trap monitor data to reliably determine the status of individual steam traps and potentially other system parameters.
Claims20
A sensing device, comprising:
- one or more sensors configured to generate one or more sensor signals;
- one or more transmitters configured to transmit sensor data representing the one or more sensor signals to a remote device;
- control circuitry configured to control operation of the one or more transmitters, and to convert the one or more sensor signals to the sensor data;
- a first device configured to harvest a first energy from an environment in which the sensing device is deployed;
- a second device configured to harvest a second energy different than the first energy from the environment;
- an energy storage device configured to store energy derived from a combination of the first energy and the second energy;
- and
- power management circuitry configured to control the storing of the energy derived from the combination of the first energy and the second energy by the energy storage device.

A monitor, comprising:
- one or more sensors configured to generate one or more sensor signals;
- one or more transmitters configured to transmit sensor data representing the one or more sensor signals to a remote device;
- a wakeup receiver configured to receive a wakeup message from the remote device;
- control circuitry configured to control operation of the one or more transmitters, and to convert the one or more sensor signals to the sensor data, wherein the control circuitry is further configured to wake up in response to the wakeup message;
- a first device configured to harvest a first energy from an environment in which the monitor is deployed;
- a second device configured to harvest a second energy different than the first energy from the environment;
- an energy storage device configured to store energy derived from a combination of the first energy and the second energy;
- and
- power management circuitry configured to control the storing of the energy derived from the combination of the first energy and the second energy by the energy storage device.
