Abstract

A communication system for a climate-controlled container. The system includes a controller and a radio expansion module removably connected to the controller. The controller is coupled to the refrigerated container and configured to monitor a status of the refrigerated container. The radio expansion module is configured to support a communication mode, and to communicate the status to a remote system. The communication mode used to communicate with the remote system is determined by the controller based on the communication modes supported by the radio expansion module.

Claims

1. A communication system for a climate-controlled container, the system comprising:

a controller coupled to the climate-controlled container and configured to monitor a status of the refrigerated container; and

a radio expansion module removably connected to the controller and configured to support a communication mode, the radio expansion module configured to communicate the status to a remote system;

wherein a communication mode used to communicate with the remote system is determined by the radio expansion module based on the communication modes supported by the radio expansion module.

2. The system of claim 1, wherein the radio expansion module includes a plurality of different communication modes.

3. The system of claim 2, wherein the radio expansion module selects which of the plurality of different communication modes to use based on at least one of cost of the communication mode, security of the communication mode, signal strength of the communication mode, and signal integrity of the communication mode.

4. The system of claim 1, wherein the communication mode includes at least one of cellular, satellite, WiFi, wireless personal area network, and radio frequency.

5. The system of claim 1, wherein the radio expansion module includes a third-party telematics connection.

6. The system of claim 1, wherein the controller communicates, via the radio expansion module, with a personal area network.

7. The system of claim 6, wherein the radio expansion module receives a status of at least one of the refrigerated container and a vehicle via the personal area network.

8. The system of claim 1, wherein the controller executes a first program, receives a second program from the remote system, stores the second program in a memory, and executes the second program, the second program replacing the first program.

9. The system of claim 1, wherein the radio expansion module is connected to a sensor of the climate-controlled container, the radio control module receiving an indication of a status of the climate-controlled container from the sensor.

10. A communication system, the system comprising:

a controller coupled to a device to be monitored, the controller configured to monitor a status of the device; and

a first radio expansion module configured to be removably connected to the controller, the first radio expansion module configured to communicate the status to a remote system via a first communication mode;

a second radio expansion module configured to be removably connected to the controller, the second radio expansion module configured to communicate the status to the remote system via a second communication mode.

11. The communication system of claim 10, wherein the second communication mode is different than the first communication mode.

12. The communication system of claim 10, wherein the first and second radio expansion modules are configured to support three or more communication modes.

13. The communication system of claim 12, wherein at least one communication mode supported by the first radio expansion module is not supported by the second radio expansion module.

14. The communication system of claim 12, wherein at least one communication mode supported by the second radio expansion module is not supported by the first radio expansion module.

15. A method of communicating by a communication controller with a remote system, the method comprising:

connecting to a removable radio expansion module populated with a plurality of circuits for communicating, each of the plurality of circuits providing a different communication mode;

obtaining data from a device external to the communication controller;

determining a communication mode to use to send the data to the remote system; and

sending the data to the remote system via the radio expansion module using the determined communication mode.

16. The method of claim 15, further comprising connecting to a second radio expansion module mounted in place of the radio expansion module.

17. The method of claim 16, wherein the sending the data to the remote system is performed via the second radio expansion module.

18. The method of claim 16, wherein the second radio expansion module supports at least one communication mode different from a communication mode supported by the radio expansion module.

19. The method of claim 15, receiving a new program from the remote system, a controller replacing an existing program with the new program.

20. A communication system for a climate-controlled container, the system comprising:

a controller coupled to the climate-controlled container and configured to monitor a status of the refrigerated container; and

a radio expansion module removably connected to the controller and configured to support a plurality of communication modes including at least two of cellular, satellite, and WiFi, the radio expansion module configured to communicate the status to a remote system;

wherein when a WiFi communication link is available and the radio expansion module is configured to support a WiFi communication mode, the controller communicates with the remote system via a WiFi communication link;

wherein when a WiFi communication link is not available or the radio expansion board is not configured to support a WiFi communication mode and a cellular communication link is available and the radio expansion board is configured to support a cellular communication mode, the controller communicates with the remote system via a cellular communication.

21. The system of claim 20, wherein when a WiFi communication link is not available and a cellular communication link is not available and the radio expansion board is configured to support a satellite communication mode, the controller communicates with the remote system via a satellite communication link.

22. The system of claim 20, wherein the controller executes a first program, receives a second program from the remote system, stores the second program in a memory, and executes the second program, the second program replacing the first program.
