US 2023/0366390 A1 · DUPLEX CONTROL OF REDUNDANT PASSIVELY-ACTUATED ELECTRONIC DEVICES

Abstract

The present application generally relates a system for duplex control of redundant passively-actuated electronic devices. In one embodiment, the system comprises a housing, a controller mounted inside the housing, an input/output (I/O) interface integrated with the housing that includes a first port configured to electrically couple a power input to the controller, a second port configured to electrically couple a first pump to the controller, and a third port configured to electrically couple a second pump to the controller, and a set of relays connected to the second port and the third port. In response to a current sensing circuit sensing that a first current indicates that the-first pump has shut off, the controller may activate the second pump and deactivate the first pump by controlling the set of relays to disconnect the power source from the first pump and to connect the second pump to the power source.

Dependent claims

A system comprising:

a housing;
a controller mounted inside the housing;
an input/output (I/O) interface integrated with the housing, wherein the I/O interface includes:
a first port configured to electrically couple a power input to the controller,
wherein a power source is based on the power input;
a second port configured to electrically couple a first pump to the controller;
and
a third port configured to electrically couple a second pump to the controller, and
a set of relays connected to the second port and the third port,
wherein the controller includes a current sensing circuit configured to sense (i) a first current drawn by the first pump and (ii) a second current drawn by the second pump, and
wherein, in response to the current sensing circuit sensing that the first current indicates that the-first pump has shut off, the controller activates the second pump and deactivates the first pump by controlling the set of relays to disconnect the power source from the first pump and to connect the second pump to the power source.

A method comprising:

measuring current being provided by a power source to a first pump, wherein the first pump is electrically coupled to a first port of an input/output (J/O) interface;
identifying a first current measurement indicating that the first pump has shut off;
and
in response to identifying the first current measurement:
activating a second pump electrically coupled to a second port of the I/O interface, wherein activating the second pump is performed by controlling a set of relays to connect the power source to the second pump, and wherein the power source is derived from a power input electrically coupled to a third port of the J/O interface;
and
deactivating the first pump, wherein deactivating the first pump is performed by controlling the set of relays to disconnect the first pump from the power source.
