Systems and methods for real-time detection and communication of health and performance degradation in a distributed building automation network

A method for determining a health status of one or more devices in a building control system, the method comprising:

• receiving a health message at a first device from a second device via a network of the building control system;
• updating a stored health message stored in the first device with data from the received health message, wherein updating the stored health message comprises:
• updating a message list of the stored health message;
• updating a sick node list of the stored health message;
• and
• updating a sick node matrix of the stored health message;
• determining if the one or more devices in the building control system are sick by evaluating the updated sick node matrix;
• generating an alert based on the evaluated updated sick node matrix;
• and
• transmitting the stored updated health message to an individual device on the network.

A method for determining health and performance of one or more devices in a building management system (BMS), the method comprising:

• receiving a health message during a first messaging cycle at a first device from a second device of the BMS, wherein the second device is one of a plurality of devices of the BMS;
• updating a message list, a sick node list, and a sick node matrix of the first device with data from the received health message, the received health message comprising a received message list, a received sick node list, and a received sick node matrix, wherein updating further comprises setting a heartbeat value associated with the second device to zero in the message list of the first device;
• evaluating the updated sick node matrix to determine if a consensus of the devices have indicated that the one or more devices in the BMS are sick, wherein the devices determine if the one or more devices are sick based on a heartbeat value associated with each device exceeding a predetermined value;
• and
• generating an alert based on the evaluation of the updated sick node matrix.
