Abstract:
1. A system for monitoring a drilling rig operation, comprising: a drilling rig assembly comprising a top drive assembly, the top drive assembly having a member extending therefrom to engage a pipe; at least one sensor coupled to the member to sense a parameter related to operation of the drilling rig assembly; a client device coupled to the at least one sensor outside of the member, the client device comprising a data acquisition device that is receiving data from the at least one sensor, and the client device comprising a sensor and a first radio, wherein the first radio is coupled to the data acquisition device, and the client device removably mountable to the member; and a base station located a distance from the client device, and the base station comprising a second radio that communicates wirelessly with the first radio in order to transfer the data between the data acquisition device and the base station; wherein the client device changes power states based on an output of the at least one sensor, the output comprising rotation of the member of the drilling rig assembly; wherein an auto-power state occurs when a signal of the client device is within a predefined threshold and allows the first radio to continue to operate in a high-power state for a flexible period of time; and wherein when to power-up or power-down the client device is determined based on a signal strength of the sensor of the client device.
