Internet of things gateway systems and methods for oil and gas fields
Certain aspects of the present disclosure provide for wireless sensor packages to monitor various oilfield equipment health status, such as bearing wear and detect out-of-balance condition on reciprocating rod lifts (RRLs). Equipment health data can be collected, analyzed and stored by an IoT gateway, which is a small form-factor, ruggedized, low-power Intel processor computer running a novel message-oriented middleware software stack that leverages the MQTT protocol. Data may subsequently be transmitted to a cloud service via the internet via to a datacenter through SCADA, for analysis and action.
