Abstract

An asset management system includes an asset management network that connects various types of refrigeration appliances to an asset manager. At the device layer, IOT devices are connected to the refrigeration appliances and have edge compute capability, including a backup power management function, and a modem for network communication. IOT device ports directly integrate with sensors, switches, and/or serial data controllers of refrigeration appliances. Push notification alarms are initiated on the edge of the network by IOT devices. The network tags operating data by appliance serial, and the asset manager stores the data using serial numbers as primary keys. The asset manager streams data from numerous appliances and uses event driven processing to promptly respond to edge alarms. The operating data keyed by serial number is enriched with proprietary data organized by appliance type and is used to develop new predictive models by appliance type.

Claims15

Dependent claims

An IoT device for connecting a refrigeration appliance to a remote asset management system, the IoT device comprising:

an edge computing device configured to be operatively connected to the refrigeration appliance for reading operating data from the refrigeration appliance;
and
a modem configured for network communication, the edge computing device configured to control transmission of operating data read from the refrigeration appliance to the asset management system via the modem;
a main power port configured to connect the IoT device to main power;
and
a backup power supply configured to power the IoT device in a main power outage;
wherein the edge computing device is configured to recognize loss of main power at the main power port, and in response, conduct a power failure routine in which the edge computing device, drawing power from the backup power supply:
transmits a power outage alarm notification to the asset management system;
subsequently samples operating data from the refrigeration appliance during a low power time interval without transmitting the sampled operating data to the remote asset management system;
after the lower power time interval elapses, automatically puts the IoT device in a sleep mode in which the edge computing device ceases sampling the operating data from the refrigeration appliance;
and
via the modem, automatically reports the sampled operating data from the low power time interval to the asset management system when restored main power is detected at the main power port.
