Maintenance self-diagnosis and guide for a self-contained wastewater treatment system

A self-diagnostic maintenance system for a self-contained wastewater treatment system, comprising:

• a plurality of sensors mounted on the self-contained wastewater treatment system, each of the plurality of sensors associated with a component of the wastewater treatment system;
• a data logger configured to gather data from the plurality of sensors;
• a controller, operatively coupled to the data logger;
• a memory operatively coupled to the controller;
• a software application, stored in the memory and executable by the controller, having:
• a plurality of hierarchically-organized sensor object classes, including
• a sensor object superclass that defines variables and methods common to all of the sensors, one or more communication protocol object subclasses each of the communication protocol object subclasses further defining variables and methods to communicate with one or more of the sensors using a predetermined communication protocol,
• one or more individual sensor object subclasses each of the individual sensor object subclasses further defining variables and methods to communicate with an individual sensor of the sensors, wherein the variables are unique to the individual sensor and are not common to other sensors in the system that use the same communication protocol as the individual sensor;
• and
• a failure detection object class that defines one or more methods to analyze data from the sensors to determine whether a failure mode exists in the system;
• a communication interface operatively coupled to the controller;
• a plurality of threshold values corresponding to each of the sensors stored in the memory for use by the software application in determining modes of system failure;
• wherein the software application, when executed by the controller, configures the controller to:
• upload the sensor data from the data logger;
• time stamp the uploaded sensor data;
• generate a data object consisting of the uploaded sensor data, time stamps and names recorded in a data structure;
• perform one or more arithmetic operations on the uploaded sensor data to produce resultant data;
• compare the resultant data against the plurality of corresponding threshold values to create a Boolean array of values, wherein each of the values in the Boolean array is associated with one of the sensors and indicates whether or not a failure mode of the self-contained wastewater treatment system has occurred, wherein each failure mode is associated with failure of one of the components of the wastewater treatment systems;
• wherein the communication interface is configured to send a message through a communication network to alert a maintenance operator of the failure model and
• wherein the system is configured to provide the maintenance operator with instructions for replacing or repairing the component of the wastewater treatment system that is associated with the failure mode, either by using an on-site display or by the message sent through the communication network.
