1. A method for determining a status of a container handler configured to move a container, comprising:

  • receiving a container code of the container handled by the container handler from an optical character recognition (OCR) component configured to sense the container code to provide an optical container characteristic including at least one instance of a member of a container code characteristic list, wherein the container code characteristic list includes a container code text, a view of the container code, and a compression of the view of the container code;

    receiving data from a plurality of sensors deployed proximate the container handler to determine one or more states of the container handler;

    receiving data of the one or more states from the plurality of sensors in a microcontroller module configured to provide at least one member of a crane state list specifying a configuration of a structure element with respect to a twistlock state, spreader state, landing state, trolley position, or hoist height of the container handler to generate a sensed state of the container handler; and

    wirelessly transmitting the sensed state for the container handler to a computer of a terminal operating system for determination of a state of the container handler as part of a container inventory management system.
