- the air dryer unit 12 ’and the air treatment system 14’ are also set up to carry out the inventive method described above.
- FIG. 3 shows a schematic illustration of a commercial vehicle 16, 16 ′′, which may have the first or second exemplary embodiment of the system 10, 10 ′′ according to FIG. 1 or FIG. 2.
- the air treatment system 14, 14 ′′ also has a control unit 40a, 40a ’, which can have the evaluation device 34, 34’ described above.
- the control unit 40a, 40a ' is also connected to a further vehicle control unit 40b, 40b' via a wired data connection.
- a mobile terminal 40c is also provided for a vehicle driver, which is designed, for example, as a smartphone or as a tablet.
- a data transmission antenna 44, 44 ' is also shown, which is connected to both the vehicle antenna 42, 42 "and a central server 46, 46"
- Production plant 48, 48 ’e.g. for the production of air dryer units 12, 12 is in wireless data connection.
- the mobile terminal 40c, 40c ’with the control device 40a, 40a’, with the further vehicle control device 40b, 40b ’, with the data transmission antenna 44, 44’ and / or with the vehicle antenna 42, 42 ’ are in wireless data connection.
- FIG. 4 shows a schematic illustration of a flowchart for carrying out a method according to the invention in accordance with steps S1 to S5 by means of the first or second exemplary embodiment of the system 10, 10 ′ according to the invention.
- Air dryer unit 12, 12 replaced after a definable life.
- the new air dryer unit 12, 12 ' is initialized from the production plant 48, 48' in accordance with an initialization step S1, with the initialization step S1 storing initialization data in the form of some specific information of the
- Air dryer unit 12, 12 ' such as:
- control number is in the production plant 48, 48 ’after non-public
- a new air dryer unit 12, 12 ′′ can also be understood as an original air dryer unit 12, 12 ’that has been repaired based on a used condition by the manufacturer himself or by a repair company authorized by him.
- the reading step S2 at certain times can also be carried out automatically or by triggered wake-ups of the control devices 40a, 40a ’; 40b, 40b '.
- the reading step includes, for example, reading the date, the counting information and the control number from the RFID chip 24, 24 ’of the new or
- the writing step S3 at certain times can also be function-dependent, automatically or by means of triggered shutdown processes by the respective control devices 40a, 40a '; 40b, 40b 'or permanently in each control unit cycle.
- the count information cannot be overwritten and / or stored if the count information is smaller than the count information already stored.
- a plausibility check step S4 the data read by the RFID chip 24, 24 'in the control unit 40a, 40a' of the air treatment system 14, 14 'and / or the commercial vehicle 16, 16' and / or in the central server 46, 46 ' (eg in a production plant 48, 48 ') and can be checked for plausibility.
- the plausibility check step S4 can be carried out, for example, with regard to the count information when a new air dryer unit 12, 12 ′ with the count information zero or another unambiguous initial value in one
- Air treatment system 14, 14 '(outside the production plant 48, 48') is recognized.
- the algorithms used in the control unit 40a, 40a ’and from the production plant 48, 48 ′′ can also be used based on their respective
- Results are compared and thereby checked for plausibility.
- Such a check can in particular be checked for plausibility in such a way that if, after changing the calculation algorithm for the control number, the control number read by the RFID chip 24, 24 ′ changes in accordance with an algorithm that is no longer permitted.
- the evaluation or the use of the data can be used in particular to identify piracy products in connection with air dryer units 12, 12 '.
- a further application or use of this data can be according to a
- Evaluation step S5 for statistical evaluation of the product behavior and for triggering maintenance instructions (e.g. display on the mobile terminal 40c or in the commercial vehicle 16, 16 'itself with regard to the end of the service life or pirate product,
- maintenance instructions can also be subject to all other wear and tear that are to be regularly replaced and are subject to particular wear Components or operating media (such as filters, brake components, oils, etc.) are used.
- the data determined as described above can be used as part of the evaluation step S5 for an update of the control unit and / or production plant algorithm to calculate the control number.
- This algorithm could thus be updated if, in accordance with the plausibility step S4, it is recognized that counterfeiters are using the algorithm currently used for external control device write operations on the RFID chip, in order to enable the use of inferior piracy components if necessary.
