Distributed data management systems for embedded controllers

A method for managing data in an industrial production environment, the method comprising:

• executing, by a first embedded controller, programming logic to generate process data based on sensor data collected from one or more production devices in the industrial production environment;
• performing, by the first embedded controller, a data monitoring process comprising:
• reading, by the first embedded controller, the process data and the sensor data during execution of the programming logic, and
• inserting the process data and the sensor data into a controller database in the first embedded controller, wherein the controller database is part of a distributed database stored on the first embedded controller and a plurality of second embedded controllers;
• receiving, by the first embedded controller, a database processing request;
• determining, by the first embedded controller, one or more of the second embedded controllers storing portions of the distributed database needed to respond to the database processing request;
• transmitting, by the first embedded controller, a processing instruction to each of the one or more of the plurality of second embedded controllers;
• receiving, by the first embedded controller, processed sensor data from the one or more of the plurality of second embedded controllers in response to the processing instruction;
• creating, by the first embedded controller, a response to the database processing request by aggregating the processed sensor data;
• and
• responding, by the first embedded controller, to the database processing request.

A method for managing data in an industrial production environment comprising a plurality of embedded controllers, the method comprising:

• for each embedded controller in the industrial production environment, inserting sensor data into a controller database in the embedded controller, wherein the controller database is part of a distributed database stored across the plurality of embedded controller;
• receiving a database processing request by a first embedded controller included in the plurality of embedded controllers;
• determining, by the first embedded controller, one or more of the second embedded controllers storing portions of the distributed database needed to respond to the database processing request;
• transmitting, by the first embedded controller, a processing instruction to each of the one or more of the plurality of second embedded controllers;
• receiving, by the first embedded controller, processed sensor data from the one or more of the plurality of second embedded controllers in response to the processing instruction;
• creating, by the first embedded controller, a response to the database processing request by aggregating the processed sensor data;
• and
• responding, by the first embedded controller, to the database processing request.
