AUTOMATIC AUXILIARY-POWER DETECTOR FOR POOL SYSTEMS

摘要

Systems and methods for controlling power on a communication network bus connecting an auxiliary device and a control device in a pool or spa system. The control device includes a power source for providing voltage to the device and a power detector. The auxiliary device can provide additional voltage to the control device via the communication network bus. The power detector may be capable of detecting voltage received by the control device via the communication network bus. The power detector may also be capable of detecting traffic (e.g., communication) by the control device or the auxiliary device via the bus and/or data collision on the bus. The power detector is configured to enable or disable the power source of the control device based on voltage detected on the communication network bus, traffic detected on the communication network bus, and/or data collision detected on the communication network bus.

主权项

1. An auxiliary power detection system for a pool or spa comprising:
a control device that is couplable to at least one auxiliary device via a communication network bus, wherein the control device comprises:
a power source that powers the control device;a regulator communicatively coupled to the power source, wherein the regulator is configured to receive voltage from the power source and wherein the regulator outputs the received voltage when enabled and prevents output of the received voltage when disabled; anda power detector communicatively coupled to the regulator, wherein the power detector is configured to detect an amount of auxiliary voltage received by the control device from the auxiliary device via the communication network bus and wherein the power detector enables or disables the regulator based on the detected amount of the auxiliary voltage.
