Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims benefit under 35 U.S.C. §119(e) from a United States Provisional Patent Application of Hill, Donald John, et al. entitled “A System and Method of Remote Diagnostics”, Ser. No. 60/889,774, filed on Feb. 14, 2007, the entire contents being incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a remote diagnostics system and method. In particular, although not exclusively, the present invention relates to a system and method for remotely diagnosing a vehicular guidance device.

BACKGROUND TO THE INVENTION

Off-road vehicles typically utilised in, for example, agricultural, construction, mining and forestry applications, such as tractors, harvesters, diggers, graders, dump trucks and other powered vehicles, commonly comprise electronic equipment designed to assist an operator in guiding the vehicle along a particular path.

In particular, agricultural vehicles, such as tractors, harvesters and the like, often include a guidance device that includes a Global Positioning System (GPS) unit and display to guide the vehicle along a predetermined path using positional data provided by the GPS constellation of satellites as an aide.

Moreover, it is known to use guidance devices that include GPS units on agricultural vehicles such that a course may be stored within the guidance device and the guidance device operates the vehicle in a semi-autonomous manner.

Alternatively, the guidance device provides direction to an operator of the agricultural vehicle to enable the operator to maintain a predetermined fixed path when, for example, harvesting crops with the vehicle.

However, like all high technology equipment, it is not uncommon for guidance devices that are utilised in agricultural vehicles to fail and, from the point of view of the user at least, without any apparent reason. As such, it is necessary to have a skilled technician travel to the site in order to diagnose and correct the fault in the guidance device.

Often these faults are transient and stem from situations such as communication errors between a base station guidance sub-module of the guidance device and an on-board guidance sub-module due to the terrain and obstructions between the sub-modules.

Given the often remote locations in which agricultural vehicles operate, a failure of the guidance device may result in a long period of down time whilst the technician travels to a site in order to diagnose and correct the fault.

Often, a fault with a guidance device on an agricultural vehicle is relatively simple for a skilled technician to correct and requires a relatively small amount of time on site compared with the relatively large amount of time required for the diagnostician/technician to travel to the site.

It is known in the art to remotely diagnose the performance of a vehicle. For example, U.S. Pat. No. 6,611,740 describes a system for monitoring a vehicle that includes a wireless appliance in electrical contact with an in-vehicle computer. The system described allows a remote diagnostician to interface with a computer on the vehicle to obtain data relating to the performance of the vehicle.

Furthermore, JP10-5427 describes a diagnostic tool for automobiles that notifies a nearby service station of a malfunction condition in relation to the performance of the vehicle.

Whilst the systems described above adequately provide for remote diagnostics of vehicles, remotely diagnosing a vehicle guidance device has a different set of problems that are not catered for by these prior art systems.

Hence, it is desirable to provide a system and method of remotely diagnosing a vehicular guidance module.

In this specification, the terms “comprises”, “comprising”, “includes”, “including” or similar terms are intended to mean a non-exclusive inclusion, such that a method, system or apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed.

Optionally, the method further includes the step of retrieving image data from a spatial-data provider based upon the location data; and communicating the image data to the service provider entity.

Preferably, the method further includes the step of displaying the performance data of the guidance device to the service provider entity such that the service provider entity obtains a display identical to a display of the performance data provided by the guidance device.

Suitably, the service request message is communicated by a user of the guidance device by the user selecting a service request function displayed on a display of the guidance device.

Preferably, the method further includes the step of communicating a configuration instruction message from the service provider entity to the communication module of the guidance device.

Diagnostics module 200 comprises a data store 210 and an interface module 22Q in communication with data store 210. Data store 210 of diagnostics module 200 stores a plurality of guidance device identifiers in association with a relevant service provider entity 300.

Suitably, data store 210 of diagnostics module 200 maintains a list of guidance device identifiers stored in association with a service provider entity 300.

In a preferred form, the interface module 220 is in the form of an Internet interface to provide a web based interface to the diagnostics module 200.

Alternatively, the interface module 220 is in the form of an interface to facilitate communications with the diagnostics module 200 by way of proprietary software.

The function of diagnostics module 200 is discussed in greater detail below.

As discussed, system 1000 further comprises a plurality of service provider entities 300 in communication with network 500. Suitably, each service provider entity 300 is in the form of a computing device as is known in the art having communication capabilities and operable by a diagnostician responsible for diagnosing and solving errors with a respective guidance device 100 as will be discussed in greater details below.

Optionally, a spatial data provider 400 forms part of system 1000. Spatial data provider 400 provides image data in the form of satellite imagery and/or terrain information in response to a request message containing location data, such as latitude and longitude co-ordinates. There are many known, commercially available spatial data providers 400, such as Google™ Maps and other similar applications and spatial data provider 400 may be in the form of any of these known applications.

Alternatively, spatial data provider 400 may be in the form of a proprietary application able to communicate image data in the form of satellite imagery and/or terrain information in response to a request message containing location data, such as latitude and longitude co-ordinates.

The system 1000 of remote diagnostics functions to provide a means for a diagnostician/technician of a guidance device 100, located upon an agricultural vehicle or the like, to efficiently and effectively diagnose and/or correct faults occurring with the guidance device 100 whereby the diagnostician/technician is able to diagnose and/or correct these faults from a location remote from the guidance device.

FIG. 2 shows a method 2000 of remote diagnostics according to a further embodiment of the invention.

The method 2000 commences when a user of the guidance device 100 is in need of assistance from a diagnostician or technician skilled in the operation of the guidance device 100 due to a fault in the guidance 100 device or a perceived fault in the guidance device 100.

The user communicates a service request message from the communication module 110 of the guidance device 100 to the diagnostics module 200 and the diagnostics module 200 receives the service request message from the communication module 110 of the guidance device 100 (Step 2100).

The service request message includes the guidance device identifier stored in the processor 120 of the guidance device 100 and the network address of the communication module 110 of the guidance device 100 as will be discussed in greater detail below.

Optionally, the service request message also includes fault data supplied by the user of the guidance device 100 relating to details of the fault.

In a preferred form, the communication of the service request message is initiated by the user of the guidance device 100 by the user selecting a service request function displayed on the display unit 140 of the guidance device 100. This action triggers the communication module 110 of the guidance device 100 to communicate the service request message to the diagnostics module 200.

Preferably, the communication module 110 creates a connection with network 500 in the form of the Internet and communicates the service request message to the interface module 220 of the diagnostics module 200 via the Internet 500.

As such, the network address of the communication module 110 of the guidance device 100 is in the form of an Internet Protocol (IP) address assigned to the communication module 110 when the communication module establishes a connection with network 500.

As the IP address of the communication module 110 will differ each time a service request message is received, the diagnostics module 200 stores the network identifier of the communication module 110 for further communication.

Optionally, the service request message may be communicated to the diagnostics module 200 using Voice over IP (VOIP) or a telecommunications messaging protocol such as SMS or the like.

The diagnostics module 200 then identifies a service provider entity 300 associated with the guidance device 100 (Step 2200).

The diagnostics module 200 extracts the guidance device identifier form the service request message and queries data store 210 to determine the relevant service entity provider 300 responsible for diagnosing and correcting faults in the guidance device 100.

As mentioned, the data store 210 maintains a list of all guidance device identifiers and associates details of the relevant service entity provider 300 in association with each guidance device identifier.

As previously discussed, there may be a plurality of service provider entities with each service provider entity responsible for diagnosing and correcting faults in only a subset of all guidance devices 100 due to, for example, contractual reasons or due to a specific service provider entity 300 only begin capable of servicing a particular configuration of the guidance device 100 and not others.

The diagnostics module 200 then notifies the identified service provider entity 300 of the service request message (Step 2300).

Preferably, the data store 210 of the diagnostics module 200 also stores contact information associated with the identified service provider entity 300 and a notification method preferred by the identified service provider entity 300.

For example, the data store 210 of the diagnostics module 200 may contain an e-mail address associated with the identified service provider entity 300 and the diagnostics module 200 notifies the identified service provider entity 300 of the service request message received from the guidance device 100 by way of e-mail.

Optionally, the diagnostics module 200 may notify the identified service provider entity 300 of the service request message received from the guidance device 100 by communicating a text message to a designated cellular phone.

Alternatively, a call may be placed to the identified service provider entity 300.

The diagnostics module 200 then places the identified service provider entity 300 in communication with the communication module 110 of the guidance device 100 (Step 2400).

In a preferred form, this is carried out by the diagnostics module 200 commencing a new session in relation to the service request using the interface module 220 to provide a private dedicated web interface between the identified service provider entity 300 and the communications module 110 of the guidance device 100. The diagnostics module 200 utilizes the network address of the communications module 110 of the guidance device 100 to create this interface.

As such, the notification message discussed above with reference to step 2300 preferably includes a web address identifying the session created in the interface module. Preferably, the dedicated session also includes password authentication to enable the identified service provider entity 300 to be placed in communication with the communications module 110 of the guidance device 100 by the diagnostics module 200.

The diagnostics module 200 then facilitates communication between the communication module 110 of the guidance device 100 and the service provider entity 300 (step 2500).

In particular, the interface module 220 of the diagnostics module 200 receives performance data associated with the guidance device 100, as previously described, and communicates this performance data to the identified service provider entity 300 by way of the created session to enable diagnosis of the fault or perceived fault in the guidance device.

In a preferred embodiment, the diagnostics module 200 is configured to display in the session via the interface module 220 the performance data of the guidance device 100 such that the identified service provider entity 300 receives a display identical to a display of the performance data provided by the guidance device 100 to the user of the guidance device 100. An exemplary display, according to an embodiment of the invention, provided to the identified service provider entity 300 is shown in FIG. 3.

Furthermore, the diagnostics module 200 is configured to facilitate communication of configuration instruction messages from the identified service provider entity 300 to the communication module 110 of the guidance device 100.

Preferably, the configuration messages include instruction data relating to reconfiguring the guidance module 100 in light of a fault diagnosed by the service provider entity 300. Optionally, the configuration messages may include textual data instructing a user of the guidance device to attempt tasks in an effort to trouble shoot the fault.

Additionally, the configuration message may be in the form of a firmware update message containing data to update the firmware operating on the processor 120 of the guidance device 100.

Optionally, the diagnostics module 200 is in communication with the spatial data provider 400 to retrieve image data from the spatial data provider 400 based upon location data received from the communication module 110 of the guidance device 100 as previously discussed. The interface module 220 of the diagnostics module 200 is configured to communicate the image data to the identified service provider entity 300 to help better diagnose the fault of the guidance device 100

For example, the positioning module 130 of the guidance device 100 may be located under a terrain based obstruction, such as a tree, and this obstruction may be interfering with the positioning calculations. As the identified service provider entity 300 is able to obtain the image data, in the form of spatial imagery and/or terrain information, in relation to the location of the guidance device 100, a diagnostician is able to actually view whether there are features of the terrain interfering with, for example, an antenna of the positioning module 130 of the guidance device 100.

In an embodiment of the invention, the performance data communicated by the guidance device 100 may also include data relating to the status of the guidance device, software configured to operate on the processor 120 of the guidance device 100, history data stored by the processor of the guidance device 100 in respect of paths taken by the vehicle upon which the guidance device 100 is located and the like, and performance data.

The system and method of remote diagnostics of the invention functions to provide a means for a diagnostician/technician of a guidance device 100, located upon an agricultural vehicle or the like, to efficiently and effectively diagnose and/or correct faults or perceived faults occurring with the guidance device 100 whereby the diagnostician/technician is able to diagnose and/or correct these faults or perceived faults from a location remote from the guidance device.

Furthermore, feature of the invention delivers information to the diagnostician that may otherwise not have been communicated to the diagnostician by the user of the guidance device.

Throughout the specification the aim has been to describe the present invention without limiting the invention to any one embodiment or specific collection of features. Persons skilled in the relevant art may realize variations from the specific embodiments that will nonetheless fall within the scope of the present invention.
