METHODS AND SYSTEMS RELATED TO REMOTE POWER LOSS DETECTION

摘要

Remote power loss detection. At least some of the example embodiments are methods including: tracking location of an asset by an onboard device mechanically coupled to the asset, the onboard device electrically coupled to a source of power of the asset, and the onboard device receiving power from the asset; charging a supercapacitor coupled to the onboard device; and then detecting a complete loss of power provided to the onboard device, and the detecting by the onboard device; and after the complete loss of power sending a message by wireless transmission, the sending based on power derived from the supercapacitor, and the message including an indication of a last known voltage provide by the asset prior to the complete loss of power, and the sending by the onboard device after the complete loss of power.
