Problems solved by technology

Vibration recuperators can be energy efficient, for example, in areas with high amplitude continuous vibrations, but may be impractical or insufficient in areas with low amplitude or intermittent vibrations
Additionally, while batteries and supercapacitors typically continue to supply power while being discharged, energy harvesting systems can experience unpredictable drops in power production, causing power levels to fluctuate based on environmental conditions

Embodiment Construction

[0016] The present invention is a power module for industrial wireless transmitters or actuators. The power module includes both an energy storage device such as a battery or supercapacitor and a power conditioning circuit for an external power harvesting energy source. Voltage readings from the power module are used to identify failure modes of the power harvesting energy and energy storage devices.

[0017] figure 1 Shown is a process measurement or control point 10 comprising a wireless field device 12 (with antenna 14), a transducer 16, a process connection 18, process piping 20, a local power source 22 and a power connection 24 . Wireless field device 12 is connected to control or monitoring system 26 via antenna 14 .

[0018] Process piping 20 carries a flow F of process fluid. Wireless field device 12 may be a process transmitter configured to receive, process, and transmit signals from one or more sensors configured to measure a parameter of the process fluid. Alt...

Abstract

The invention discloses a wireless field device assembly, which includes a process sensor, a housing, a power supply module and a processor. Process sensors are configured to monitor process variables and generate sensor signals. A housing encloses an interior space of the wireless field device. The power module includes an energy storage device and a connection to a local power source, and is configured to be received in the wireless field device. The processor is located in the interior space and is powered by the power module. A processor generates a failure signal value for distinguishing between an energy storage device failure, a local power supply failure, and a no-failure condition.

Description

technical field [0001] The present invention relates generally to industrial process field devices, and more particularly to hybrid power modules for powering wireless industrial process field devices. Background technique [0002] The term "field device" encompasses a large number of process management devices that measure and control parameters such as pressure, temperature and flow. Many field devices are transmitters that are used as communication relays between transducers used to sense or actuate industrial process variables and remote control or monitoring devices such as computers in a control room . The output signals of sensors, for example, are often insufficient to effectively communicate with remote control or monitoring devices. The transmitter works by receiving communication from the sensor, converting that signal into a form more efficient for long-distance communication (for example, a modulated 4-20mA current loop signal, or a wireless protocol signal) a...
