Method and system for data logging in a transport refrigeration system that includes a human-machine interface
First Claim
1. A method for data logging in a refrigeration system that includes a plurality of sensors each of which monitoring a parameter of the refrigeration system, a refrigeration system controller, and a human-machine interface (HMI) that is separate from the refrigeration system controller and is connected to the refrigeration system controller via a communication link, wherein the HMI includes a first communication protocol to communicate with an external device, the method comprising:
- the refrigeration system controller receiving data from each of the plurality of sensors;
the refrigeration system controller processing the received data including determining if there is a conflict between the received data from one of the plurality of sensors and the received data from another of the plurality of sensors;
the refrigeration system controller transmitting at least one of the received data and the processed data to the HMI that is separate from the refrigeration system controller via the communication link;
the refrigeration system controller displaying at least one of the received data and the processed data on the HMI;
the refrigeration system controller controlling an operating state of the refrigeration system to obtain a desired operating condition based on at least one of the received data and the processed data; and
the refrigeration system controller transmitting, at a predetermined fixed periodic time rate, at least one of the received data and the processed data to the external device via the HMI using the first communication protocol.

Abstract
Methods and systems for controlling the collection and storage of data are described. In general, the system includes a human-machine interface (HMI), and the HMI includes an interface that is configured to receive and connect with an external device. Generally, the methods and systems involve the use of an external storage device that can store, for example, collected data and/or analyzed data.

9. A refrigeration system with data logging control, comprising:
-
a plurality of sensors, each of the plurality of sensors monitoring parameters of the refrigeration system; a refrigeration system controller configured to receive data from each of the plurality of sensors; and a human-machine interface (HMI) that is separate from the refrigeration system controller and is connected to the refrigeration system controller via a communication link, wherein the HMI includes a first communication protocol, wherein the refrigeration system controller is configured to communicate the received data to the HMI via the communication link, the HMI is configured to communicate the received data to an external device via the first communication protocol, and wherein the refrigeration system controller is further configured to; process the received data including determining if there is a conflict between the received data from one of the plurality of sensors and the received data from another of the plurality of sensors, display at least one of the received data and the processed data on the HMI, control an operating state of the refrigeration system to obtain a desired operating condition based on at least one of the received data and the processed data, and transmit at least one of the received data and the processed data to the external device via the HMI device at a predetermined fixed periodic time rate. - View Dependent Claims (10, 11, 12, 13, 14, 15)
