A clock synchronized control system includes a controller configured to control at least one function of a work machine. The controller may also be configured to select a clock source from among a plurality of external clock sources based on a predetermined order. The controller may be further configured to obtain information from the selected clock source. The controller may also be configured to use the obtained information to affect the at least one function of the work machine.

Clock synchronization for a machine control system

A method is performed to collect information in a machine including an on-board data link connecting a wireless device and at least one on-board module. The process includes providing a first operational mode for the wireless device that allows the wireless device to perform a first set of operations on data associated with the at least one on-board module and providing a second operational mode for the wireless device that allows the wireless device to perform a second set of operations on the data associated with the at least one on-board module, wherein the second set of operations is a subset of the first set of operations. The process also determines an operational mode for the wireless device based on predetermined criteria and configures the wireless device based on the determined operational mode. Further, the process includes operating the wireless device in either the first or second operational mode based on the configuring.

Method for automatic radio operational mode selection

A method and system for determining one or more desired communication services for an application. The method and system includes determining at least one application operating parameter, at least one communication operating parameter, at least one cost factor, and at least one value factor. The method and system further includes assigning a priority level to each application operating parameter, communication operating parameter, cost factor, and value factor. Additionally, the method and system includes comparing the priority levels to each other, and determining a desired communication service based on the compared priority levels.

Method and system for choosing communication services

Methods and systems of the present invention are provided for performing proxy control functions in an environment including one or more work machines. Such methods and systems may leverage one or more gateways to serve as a proxy for one or more distinct modules. A gateway, located in a work machine, may be programmed with proxy logic that performs functions associated with certain modules used in a work machine environment. The gateway may monitor a data link and retrieve broadcasted messages. The broadcasted messages may include source and/or destination module address identifiers. The gateway may retrieve messages from the data link based on a determination that the message is destined for a module for which the gateway serves as a proxy. The gateway may route a retrieved message, using a mapping structure, to the appropriate proxy logic that performs functions associated with the destination module.

A data system for work machines is disclosed. The data system has a first communication device associated with a first work machine, and a second communication device associated with a second work machine. The data system also has an offboard system in communication with the first and second communication devices. The offboard system is configured to request a first data transmission from the first work machine in response to a second data transmission being received from the second work machine.

Machine operational data collection and reporting system

A method and system are provided to perform a process of wirelessly providing software updates to a target module located in a work machine. In one embodiment, the process includes determining whether a software update condition exists for software stored in the target module and when such a condition does exist, delivering software update data from a remote off-board system to the work machine. Further, the work machine may determine a location of the target module and whether an update delay condition exists. Also, the process may include delivering the software update to the target module if no update delay condition exists, and delaying the delivery of the software update data to the target module if an update delay condition does exist.

Systems and method for remotely modifying software on a work machine

Methods and systems are provided for performing protocol conversions in an environment including a work machine having one or more modules coupled to one or more data links. Such methods and systems may leverage one or more gateways to perform tunneling, translating, and bridging operations. Tunneling processes may include receiving a message from a source module in a first protocol, encapsulating the message within transmission units of a second protocol, and transmitting the encapsulated message via the second protocol. Translating processes may include receiving, by the gateway, a message in a first data link protocol including a parameter identifier. The gateway may match the parameter identifier with a parameter identifier included in a translation table and scale associated parameter data using a scale factor corresponding to a second data link protocol. The gateway may then provide the scaled parameter data to a module using the second data link protocol.

Systems and methods for performing protocol conversions in a machine

A method and system are provided to perform a process of managing communications in an environment including a mobile work machine having one or more on-board data links connected to one or more on-board modules and a gateway and including one or more off-board data links connected to one or more off-board systems and the gateway. The process is performed by the gateway and includes receiving a request generated by a source device and transmitted on a first data link. In one embodiment, the first data link may be either one of the on-board data links and one of the off-board data links. Based on the request, the gateway selectively executes a server application that performs a server process. Further, the gateway identifies a destination device associated with the request, configures the request to a format compatible with the destination device, and provides the formatted request to the destination device. Additionally, the gateway receives a response to the formatted request generated by the destination device, configures the response to a format compatible with the first data link, and sends the response to a target device over the first data link.

Systems and methods for providing server operations in a work machine

Method and apparatus for installing data stored on electronic control modules on a remotely-located machine. The control modules installed on the machine store information regarding the data which should be stored on the other installed control modules. A processor may poll the control modules to determine if a control module is missing or blank and, if so, determine which data is missing from the machine based upon the information stored on the other control modules. The processor may communicate with an off board system to identify the appropriate software for the blank control module. The software is downloaded and flashed into the blank control module.
