  • the invention has the object to improve a method for operating such a pump.
  • the basic idea is to associate the controller of the pump unit with a digital communication unit which has an interface based on Internet protocols, so that the pump unit is provided and intended via this interface for direct connection to a digital network, an ISDN line or even a telephone call.
  • This digital communication unit is largely miniaturized, so that it can be arranged within the pump unit.
  • a separate external module may also be provided which is incorporated at any point between the pump control and the line connection.
  • Such an arrangement will be particularly advantageous in compact designs such as downhole pumps or series that are only produced in small numbers. It is made possible that the pump set can be directly connected to today's widespread computer networks, whereby a computer control, as it is already possible in larger plants, for example in the field of chemistry, also possible with conventional pumps.
  • TCP / IP Transport Control Protocol / Internet Protocol
  • LAN local area network
  • IP Internet Protocol
  • a corresponding network controller such as an Ethernet controller.
  • an ISDN controller For direct connection to the ISDN network, an ISDN controller must be provided.
  • a modem For communication via an analog telephone line, however, a modem is to be provided as an interface.
  • the pump unit is equipped so that not only can be done via a digital network control, but also at least one sensor is provided, the output signal via the Karlunkationsaku is queried.
  • This can be for example a pressure sensor, differential pressure sensor, temperature sensor or the like.
  • the unit can also be incorporated into an external, over the digital network and / or the Internet-run control
  • the main electrical and / or hydraulic variables of the unit can be queried and possibly recorded at any time.
  • the basic structure of the communication unit preferably comprises a microprocessor, a dynamic memory and a static memory and an interface to the pump controller and an external interface based on Internet protocols.
  • the static memory is expediently embodied as a rewritable memory, for example as an EPROM, and contains at least the Operating system of the communication unit, but preferably the entire software.
  • the pump unit which preferably also includes a digital controller, is conveniently connected via the line bus of the pump control with the communication unit, wherein the communication is preferably via a serial RS-485 interface, which is well known from other technical applications and therefore not in the Individual is described.
  • the software and hardware equipment of the communication unit is such that it includes a web server, since then the control via an external computer, either directly via the directly connected digital Network or Internet or indirectly via a router connected to the digital network from almost any location with an Internet browser is controlled.
  • This software / hardware configuration makes it possible to access the communication unit directly from the Internet and to interrogate the operating values made available via the sensors of the unit and / or to intervene in the control of the unit.
  • the web server it is then expedient to have a corresponding web homepage and a WAP homepage so that the communication unit can be controlled not only by means of a computer via the Internet but also, for example, by means of a mobile telephone according to the WAP standard. In this way, in the private sector very simple and flexible control options can be provided, which can be handled practically worldwide via the GSM network or another wireless network.
  • Additional software is required for communication between the web server and the pump set via the data bus.
  • a command language based on postscript has proven to be particularly favorable, which is not compiled, but is converted into the machine language by means of an interpreter.
  • a compiler is not required, on the other hand, the external software of the communication unit can be changed or replaced from the outside.
  • updates of the software by command over the Internet a variety of such equipped with communication units pump units are transmitted in a short time.
  • the communication unit if it has, which is advantageous, a port for communication with at least one other external device, form a corresponding communication for any other electrical devices.
  • a temperature sensor in the house or any other sensor can be connected via an external connection.
  • active devices such as the control of a refrigerator or a cooker, a garden pump, the control of the home lighting or any other devices can also be connected to the digital communication unit via this external connection and thus via a digital network and / or via the Internet controlled.
  • the pump set in particular its digital control is designed so that it dials itself automatically via the digital communication unit into a local network or directly to the Internet to query data at predetermined addresses by download, which in turn are used for pump control ,
  • a data request can also be made for other units that are connected to the communication unit via the external connection.
  • the pump control is controllable in dependence on the future weather data (weather forecast) available on the Internet, so that an intelligent control is possible, which also takes into account future foreseeable events.
  • a time query can also be made via the Internet, which automatically adjusts or replaces the internal clock and provides for the summer / winter time changeover or controls the night setback of the heating system.
  • data of the electricity supplier can be queried here in order to throttle the drive power, for example, at peak times.
  • the size of the building is an essential criterion when setting up the communication unit.
  • the digital communication unit described below may be constructed in less than cigarette box size using today's conventional discrete components on a single board so that it can be integrated into the terminal box or other housing adjacent the unit housing.
  • the communication unit may be structurally formed with the pump unit as a unit.
  • the digital Ltdunikationsseinheft may also be incorporated in the manner of a plug-in power supply at the end of a connecting line or in the manner of a filter within the line, z. B. in a small housing.
  • the digital communication unit 1 has an interface 2, which converts the data coming from the digital pump control to the communication unit 1 and in the reverse direction so that communication via a digital line bus 3 from or to the digital pump / motor control is possible.
  • the interface used here is a modified RS-485 interface, as commonly used in pump units of the Applicant, as far as digital control is provided.
  • the interface 2 is connected to a microprocessor 4 which controls the entire data linkage of the unit 1.
  • the microprocessor is in communication with a dynamic memory 5 (DRAM) which is used to buffer data from the microprocessor 4.
