Definitions
- the present invention relates to a method for equipping a mobile machine.
- the present invention also relates to a corresponding device, a corresponding computer program and a corresponding storage medium.
- SW software
- OTA over-the-air
- VCG vehicle connectivity gateway
- vehicle-internal control units can be expanded in this way by features that use existing sensors and actuators for new applications.
- Corresponding applications can be carried out by the manufacturer or original equipment manufacturer (OEM) of an agricultural machine - for example by means of a development kit - and offered on a digital sales platform in the cloud.
- Conceivable extensions include advanced telemetry or special agricultural functions such as targeted weed control.
- DE102015203766A1 discloses a subsystem for a vehicle with a device management client connected via an air interface to a device management server of the backend for exchanging device, vehicle and diagnostic and software update information, one connected via the air interface to a download server of the backend Download client for downloading a software update from the backend into the vehicle, software update clients connected to the download client for applying the software update and a vehicle update client connected to the download client and the software update clients for coordinating the software update.
- the invention provides a method for equipping a mobile machine, in particular a mobile agricultural machine, a corresponding device, a corresponding computer program and a corresponding storage medium according to the independent claims.
- the mobile agricultural machine can in particular be a self-propelled mobile agricultural machine, such as a tractor, a combine harvester, a harvesting machine or the like.
- the mobile agricultural machine can also be a non-self-propelled mobile agricultural machine such as a towing machine or a carrying machine.
- a towing machine is in particular a trailer to be pulled by a towing vehicle, such as a baler, a trailer for dispensing a liquid or a pourable material such as seeds or fertilizers.
- a carrying machine is in particular a machine that is mounted on a carrier vehicle, such as a tractor.
- a carrying machine can in particular be a spray device, a mower, a plow or the like.
- One advantage of this assisted onboarding process is its suitability for fully or partially automated installation of control units and other hardware as well as associated, optionally personalized software.
- the telemetry unit of the machine furthermore determines its configuration and stores a scatter value (hash, fingerprint) characteristic of the latter.
- a scatter value hash, fingerprint
- the telemetry unit determines whether its environment has changed with regard to hardware, interfaces, etc. and, if necessary, to react appropriately to such changes.
- Such a fingerprint method has the advantage that unauthorized or impermissible porting of features to other and, in particular, unsuitable machines, whose functionality could otherwise not be guaranteed, is avoided.
- the approach according to the invention not only ensures the compatibility and consistency of machines, tools and other hardware and the software operated on them, but also increases functional safety and makes it easier for both equipment manufacturers and users of the machine to comply with legal requirements.
- the successful basic diagnosis with fingerprint and a possible error log is sent to the Transferred to the back end of an orchestrator or other stakeholder and linked there with the associated device ID or serial number.
- the permanent logical connection created in this way between the telemetry unit and the machine allows the backend to carry out an automatic inventory.
- the single figure shows the data flow diagram of a method according to the invention.
- the figure illustrates the role-based sub-processes of the method using a swimlane process display (10).
- an end customer (16) turns to a retailer or other installation partner (14) and decides to purchase (18) a digital product or additional features (19) from a content provider (15).
- a content provider for example, the optimization of spraying in agriculture can be considered.
- the selected service feature (19) requires a certain infrastructure on the part of the telemetry unit, sensors, etc., which are to be configured or installed by the installation partner (14). This therefore uses a cloud application to check (25) whether the purchased digital product is compatible with the selected telemetry unit and the machine equipped or to be equipped with it, in particular whether the performance of the machine and telemetry unit meet the minimum requirements imposed by the feature (19).
- the installation partner (14) then records an identifier in the cloud application, for example by entering a serial number, scanning a QR or other barcode or RFID, which gives the backend system (12) of the orchestrator (11) the identification (3) of the telemetry unit and their linking (4) with the end customer's user account is allowed.
- the installation partner (14) also specifies the manufacturer and type of the target machine.
- the telemetry unit is linked (4) to the farmer's new account (20)
- the unit is also assigned this specification (26) (5), which includes information on the type of sprayer used, for example.
- the specification of the manufacturer and the type of ISOBUS can also be read out automatically.
- the cloud application provides program-supported step-by-step instructions for the physical installation (28).
- the installer (14) can obtain the necessary hardware and the installation location from this.
- the installer (14) is then requested to switch on the power supply to the machine.
- a different sequence of steps is of course conceivable without departing from the scope of the invention.
- the telemetry unit After switching on, the telemetry unit automatically starts a basic diagnosis (29). In this context, it is checked whether - initially regardless of the still unknown target machine - all basic functions are fulfilled, e.g. there are no short circuits in the cabling. If the check (29) of this basic functionality is successful, the telemetry unit tries to establish a connection (30) to the cloud backend (12) and to log on there. If this connection (30) is established, the operating system and other software necessary for the operation of the telemetry unit are brought up to date by downloading updates from the cloud and installing them on the telemetry unit. The scatter value (31) characterizing the configuration of the machine is also transmitted via this connection (30) and - as already described above - subordinated to the device management (27) of the system (12) (9). After the features (19) supported by the configuration have been determined, these are offered to the user (16) for installation and, if requested, can be retrofitted by the installation partner (14). Finally, a functional test is carried out so that the machine can properly perform the desired function
- Said fingerprint (31) is generated anew each time the machine is started and compared with the most recently saved state. With the next connection (30) to the backend server (12), the fingerprint (31) is stored there again.
- the function can be influenced by incompatibilities of HW and SW, which, for example, makes the blocking of the spray function appear desirable when the machine is operated with a fertilizer spreader. If the fingerprint (31) indicates - for example because of a conversion of the telemetry unit into another machine - a configuration change that is not permitted in this sense, for example with regard to injection quantities or safety-relevant parameters, the functional scope of the telemetry unit can be reduced to a minimum, Authorization of the new fingerprint (31) can be canceled.
- the fingerprint (31) consists of a variable and a static part.
- the static part of the fingerprint (31) reflects properties of the machine that uniquely identify it. A supposed change in these properties detected on the basis of the static part results in a complete blocking of the function.
- This blocking is necessary, for example, with regard to functional safety, product specification, product liability and other legal obligations.
- the mechanism described is intended, among other things, to prevent the telemetry unit from being converted into another machine without permission, which can lead to damage, for example through incorrect dosing of fertilizers or pesticides. Furthermore, it is intended to prevent a performance feature (19) from being transferred to machines that are not suitable for it.
- This method (10) can be implemented, for example, in software or hardware or in a mixed form of software and hardware, for example in the system (12) of the orchestrator (11).
