Definitions

  • the invention relates to an arrangement with a vacuum pump according to the preamble of the first claim.
  • vacuum systems are complex and spatially extended. For example, there are often several dozen turbomolecular pumps on glass coating equipment. There are also other vacuum devices such as gauges, backing pumps and the like. In such a system, it is desirable to be able to query the status of individual vacuum devices or groups thereof.
  • portable devices such as portable computers and so-called “personal digital assistants” (PDAs), which are equipped with radio communication means, the desire came to be able to use these in vacuum systems for control and control purposes.
  • PDAs personal digital assistants
  • the two European publications EP 1 497 558 A1 and EP 1 577 559 A1 propose to equip vacuum devices with radio modules and to be able to establish a connection with the control device directly to the individual vacuum devices.
  • the radio link proves to be susceptible to interference when it comes to longer radio links, as they occur, for example, in glass coating systems.
  • the prior art ( DE 10 2004 047 853 A1 ) includes a control device for at least one suction element. According to the prior art, a spatially remote from the suction device display and control device is provided. This display and operating device is used by the user to operate the suction device.
  • the communication between the display and control unit and the suction device takes place either via a radio transmission or via cable. If cables are used, this is very expensive, since they may have to be laid over a long distance. Radio links are susceptible to interference at long distances.
  • the prior art ( US 2005/0129535 A1 ) includes an arrangement with a vacuum device, which has a communication module.
  • the pump unit and the operating unit are designed as separate units. This belonging to the prior art pump unit can be further improved.
  • control unit for a vacuum device.
  • the control unit and the vacuum device are two separate devices. This arrangement can be further improved.
  • the prior art ( US 5,793,963 A ) includes a device with a control system for various devices, such as a valve positioner.
  • the valve positioner has a relay station with a radio module.
  • This device belonging to the prior art can be further improved to the extent that a saving of space is achieved.
  • the object of the invention is therefore to provide a trouble-free integration of the control devices.
  • the interference immunity is achieved in that a relay station is provided, which occurs in place of the direct communication between control unit and vacuum pump. Then only the short distance between the relay station and the control unit has to be bridged. For these, the limited transmission power of the control devices is easily enough. Since it communicates only with the relay station and can be easily ensured that it reaches all associated with her vacuum pumps the system, in contrast to the prior art ensures that the control unit all vacuum pumps of the system are detected.
  • a space-saving arrangement results from the fact that the relay station is designed as a relay module integrated into a vacuum pump.
  • control unit can communicate with a desired vacuum pump by first connecting it to a relay station. From there, forwarding takes place via further vacuum pumps to the desired vacuum pump.
  • This development simplifies the overall design considerably and is also interference-proof. If the individual vacuum pumps communicate with each other via radio, the distances are significantly shorter than between control unit and target vacuum pump. As a result, an interference-proof operation is also given here.
  • a vacuum pump 1 is connected.
  • a vacuum pump 1a with flange-mounted electronic control unit 1b.
  • This control electronics can optionally be flanged or spatially separated and connected via a cable to the vacuum pump.
  • the vacuum pump has a communication module 2, which is arranged directly on the control electronics in the example shown. It can also be separated be from this, for example, in an adjacent cabinet, and then communicate via a cable with the vacuum pump.
  • a control device 3 is used to send and receive control data and operating data, that is to perform bidirectional communication. This data can be visualized and / or stored. It is also conceivable to pass on a network, for example a Local Area Network (LAN), Wide Area Network (WAN) or the Internet.
  • the control device a commercially available laptop, a PDA, a high-performance mobile phone or the like, is equipped with a radio module 4.
  • Operating data in the context referred to here are in particular actual values which can only be read out of the vacuum pump, for example speed, software status, temperature, pressure and the like. Control data includes control commands sent to the vacuum pump, such as "on / off", “accelerate”, and the like.
  • a relay station 5 is provided in the arrangement, which has a radio module 6. This is in communication with the communication module 2 of the vacuum pump in order to send and receive control and operating data via this communication connection 7. Furthermore, the relay station is connected via its radio module 6 to the radio module 4 of the control device 3 in connection. Thus, data is exchanged between the controller and the vacuum pump via the relay station.
  • the relay station can either ensure a real-time connection between the vacuum pump and the control device or have a temporary storage in which the data is kept in full or in part.
  • the control device will usually only be temporarily connected to the relay station, for example during a routine check of the arrangement. But it can also be useful over a longer period of time Connect, for example, to collect statistical data over a period of time.
  • the second figure shows some further developments, which show the possible communication paths and their configurations.
  • the dashed lines represent a radio connection
  • solid lines represent a cable connection.
  • control unit 3 equipped with a radio module 4 is connected via radio to the radio module 6 of the relay station 5. From this go starlike connections 7, 7 'and 7 "to Hannünikationsmodulen 2, 2', 2" of vacuum pumps 1, 1 'and 1 ", which are partially designed as radio links, partly as cable connections.
  • Figure c) in turn shows a relay station 5, which is connected to a bus system 10, to which the communication modules 2, 2 'and 2 "of the vacuum pump 1, 1' and 1" are connected.
  • Part d) of the figure finally shows a chain-like structure of the communication paths.
  • a vacuum pump 11 is constructed so as to have a relay module 5 '. From this relay module, the data sent from the control unit 4 to the vacuum pump 1 "or vice versa is forwarded via the communication module 2 'to the vacuum pump 1' .
  • the chain can be constructed, as shown, with cable connections or alternatively with radio connections also with the structure after Figure part b) are combined by a connection between the vacuum pump 1 "and the vacuum pump 11 is provided.
