Definitions

  • the invention relates to a compressed air treatment system, which is composed of individual units, whereby at least one filter unit, and optionally one Controller unit and / or an oiler unit is present, the can be coupled to a control unit via a customer bus.
  • Compressed air treatment systems of this type are general known and commercially available. Each of them contained units is as far as they are electrical sensors or contains actuators individually in these known systems connected to the control unit. This means everyone Units are connected in star configuration to the control unit. The user can use the individual units Control unit, for example, he can Interaction of the individual units in the Air treatment system with the help of in the Control unit contained programmable logic Control and / or regulate controls.
  • the individual units of the known Air conditioning system can be customized by the user can be assembled in modules. The user can choose which units in its present Use case are required and selected accordingly Need to become. The selection and arrangement of each So units ultimately lay that down Compressed air treatment system.

Instead is according to the invention a decoupling between the units and provided to the control unit using the interface is made. On one side of the interface are arranged the units that have a uniform
  • System bus are interconnected.
  • the units and the System bus are completely independent of that used control unit and can therefore be independent of this control unit always be the same.
  • the customer bus provided with which the compressed air treatment system to the Control unit of the respective user can be connected can. So this other side of the interface is depends on the control unit and is in everyone Application to the control unit used in each case adapt.
  • the individual units are also sent directly to the Customer bus connectable. That way it will enables a user to view the respective units in a compressed air treatment system according to the state of the Use technology. It is understood that the The advantages according to the invention cannot then be achieved. On the other hand, however, the user gets another one Possible application of the units.
  • a first way of customization can be that for each specific protocol of the customer's bus certain interface is made available.
  • the interface can be designed as a hardware component his. But it is also possible that the adaptation to the different protocols of the customer bus in software is achieved. In this case it is the Interface around a hardware component that corresponds to the the respective protocol is programmed differently.
  • the interface for a plurality of the protocols of the customer bus is provided.
  • the interface a hardware component that is either hardware and / or the different protocols of the Customer bus is adjusted.
  • the advantage of this Interface is that a user is on and off the same interface for different control units can use. So the user does not have to look around ECU-dependent bus connections and the like care but can be targeted on application-specific compressed air treatment system focus.
  • the interface is designed as a further unit.
  • the User can then use the interface like another module use in his compressed air treatment system. This results in a uniform and in itself closed system.
  • the user just has to be Connect the control unit to this system and can then use start using the compressed air treatment system.
  • Input signals can be acted upon or are of at least one of the units output signals via the system bus dispensable. Input and Transfer output signals.
  • the compressed air treatment system 1 has a plurality of individual units on the compressed air generation and Control or regulation of the compressed air generated.
  • An input valve unit 2 is thus provided, which is acted upon by a pressure P in , and with which the entire compressed air treatment system in particular can be switched on and off.
  • a filter unit 3 is provided, which via a compressed air line with the input valve unit 2 is connected, and in particular the cleaning of the Compressed air is used.
  • the filter unit 3 for example a not shown Water separator included.
  • a pressure regulator unit 4 which is connected via a compressed air line to the filter unit 3, and in particular to the control of the compressed air to a desired target value P soll is used.
  • a distribution unit 5 is provided, which via a compressed air line with the pressure regulator unit 4 is connected, and the distribution of compressed air to the serves different application locations.
  • an oiler unit 6 is provided in the compressed air treatment system 1, which is connected to the distributor unit 5 via a compressed air line.
  • the oiler unit 6 is provided with an outlet line in which the pressure P out prevails.
  • a so-called pulse oiler can be contained, which can deliver a certain amount of oil from an oil tank to the compressed air.
  • the units 2, 3, 4, 5, 6 described each have an electrical control circuit 7, which preferably is designed in the same way in all units.
  • the Control circuit 7 is used in the respective Existing electrical signals with regard to unit consistent use throughout To process compressed air preparation system 1.
  • the compressed air treatment system 1 has a system bus 8 to which all units 2, 3, 4, 5, 6 are connected are.
  • the system bus 8 is coupled to the mentioned units with the help of the uniform Processing of the electrical signals by the Control circuit 7.
  • This uniform preparation of the electrical signals is to the protocol of the System bus 8 adapted.
  • Under the protocol of the System bus 8 is the way below be understood how the individual lines of the System bus 8 are switched electrically and like that individual signals on these lines especially in With regard to their temporal behavior and on the System bus 8 are transmitted.
  • Interface 9 provided on one side with the system bus 8 is connected. On her other side is the interface 9 via a customer bus 10 with a Control unit 11 connected.
  • Interface 9 On the side connected to the control unit 11 Interface 9 is a plurality of customer buses 10 provided that have different protocols. Under the protocol of a customer bus 10, the Understand how the individual lines of the Customer bus 10 are switched electrically and like that individual signals on these lines especially in Electrically generated with regard to their temporal behavior and transmitted on the customer bus.
  • Control devices 11 directly at the interface 9 can be connected.
  • a control device 11, thus with another protocol of the customer bus 10 works together with the corresponding Protocol provided customer bus 10 of the interface 9 connected and is therefore ready for use.
  • Protocol of the customer's bus 10 and the protocol of the system bus 8 each other correspond.
  • control unit 11 it is possible to control unit 11 immediately, So without the intermediary of the interface 9 to the Connect system bus 8.
  • the interface 9 as further unit is formed.
  • the existing ones Units 2, 3, 4, 5, 6 and the additional unit for the Interface 9 can then be modular to one uniform device can be assembled.
  • the individual Units 2, 3, 4, 5, 6 are also provided with connections, which correspond to the protocol of a customer bus 10, and via which they are sent directly to the control unit 11 can be connected.
  • the filter unit 3 for example has a 2-way valve 12 with which the mentioned Water separator can be emptied.
  • This 2-way valve 12 is driven by an input signal, which under Interposition of the control circuit 7 also on the System bus 8 is available.
  • controller unit 4 Furthermore, it is possible for the controller unit 4 to be supplied with an input signal for the desired setpoint value P soll of the pressure of the processed compressed air, and / or for the controller unit to generate an output signal which corresponds to the actually existing actual value P ist of this pressure , The input and output signals of the controller unit 4 are then again available via the control circuit 7 on the system bus 8.
  • Oiler unit 6 is supplied with an input signal, that is the delivery of a certain amount of oil to the compressed air has the consequence.
  • a 2-way valve 14 or the like may be provided.
  • An output signal is generated in the lubricator unit 6, which corresponds to the level of the oil in an oil container which the specified amount of oil is released to the compressed air. This level can in turn, for example, with the help of an ohmic displacement sensor 15 can be detected.
