Definitions

  • the invention relates to an arrangement with a vacuum device 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 up to be able to use these in vacuum systems for control and control purposes.
  • PDAs personal digital assistants
  • the two European Published Patent Applications 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 prone to interference when it comes to longer radio links as they occur, for example, in glass coating systems.
  • 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 device and vacuum device. 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 communication is only with the relay station and it can be easily ensured that it reaches all of the system's associated vacuum devices, in contrast to the prior art it is ensured that all vacuum devices of the system are detected by the control device.
  • relay station can also be realized a radio connection between relay station and vacuum device. This can be advantageous for complex systems with difficult spatial conditions. This variant works because a relay station, in contrast to a control device, which should be mobile, can be equipped with almost any wireless transmit power.
  • a space-saving arrangement results when the relay station is designed as a relay module integrated in a vacuum device.
  • An advantageous development aims to use this communication link to form a communication chain.
  • the control unit can communicate with a desired vacuum device in which it is first connected to a relay station. From there, forwarding takes place via further vacuum devices to the desired vacuum device.
  • This development simplifies the overall design considerably and is also interference-proof. If the individual vacuum devices communicate with each other via radio, the distances are significantly shorter than between the control device and the target vacuum device. As a result, an interference-proof operation is also given here.
  • FIG. 1 shows a first example of an arrangement according to the invention.
  • a vacuum device 1 is connected.
  • it is a vacuum pump 1a with flanged control electronics 1b.
  • This control electronics can optionally be flanged or spatially separated and connected via a cable to the vacuum pump.
  • the vacuum device may also be a controllable valve, a measuring tube or the like.
  • the vacuum device 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 with the vacuum device via a cable.
  • 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 device, for example speed, software status, temperature, pressure, and the like. Control data includes control commands sent to the vacuum device, 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 device 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 control device and the vacuum device via the relay station.
  • the relay station can either ensure a real-time connection between the vacuum device and the control device or have an intermediate memory 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. It may 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 communication modules 2, 2', 2" of vacuum devices 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 devices 1, 1' and 1" are connected.
  • Part d) of the figure finally shows a chain-like structure of the communication paths.
  • a vacuum device 11 is constructed so as to have a relay module 5 '. From this relay module, the data sent from the control device 4 to the vacuum device 1 "or vice versa is forwarded via the communication module 2 'of the vacuum device 1' .
  • the chain can be constructed as shown with cable connections or alternatively with radio links according to the structure Figure part b) are combined by a connection between the vacuum device 1 "and the vacuum device 11 is provided.
