  • the object of the invention is to equip a pump unit with simple means in such a way that it too can be easily controlled over greater distances.
  • the basic idea of the present invention is to control the Assign a digital communication unit to the pump set, which has an interface based on internet protocols, so that the pump unit via this interface to the immediate Connection to a digital network, an ISDN line or even Telephone line is provided and determined.
  • This digital communication unit is largely miniaturized so that they are within of the pump unit can be arranged. However, it can also be a separate external module can be provided at any point is integrated between the pump control and the line connection. A such an arrangement is particularly useful in compact designs, such as borehole pumps, or for series that only in small Quantities are produced, can be an advantage.
  • the invention enables it that the pump set is directly related to the ones common today Computer networks can be connected, whereby a computer control, as in larger plants, for example in the area of Chemistry, already done today, also possible with conventional pumps is. It is also such a control in the home and private sector possible, especially when the computer or network via a modem to the analog telephone network or via an ISDN card to the ISDN network and via it to the Internet or the communication unit directly connected to it with the appropriate interface, can be controlled practically from anywhere in the world.
  • TCP / IP T ransport C ontrol P rotocol / I nternet P rotocol
  • IP Internet protocol
  • the pump unit is preferably equipped so that not only one Control can be done via a digital network, but that too at least one sensor is provided, the output signal of which Communication unit can be queried.
  • This can be, for example, a pressure sensor, Differential pressure sensor, temperature sensor or the like. This enables the unit to also be transferred to an external one the digital network and / or the internet-based regulation can be integrated is.
  • the main electrical and / or hydraulic sizes of the unit are queried at any time and if necessary be recorded.
  • the basic structure of the communication unit preferably comprises one Microprocessor, dynamic memory and static memory as well as an interface for pump control and an interface to the outside world, which is based on internet protocols.
  • the static Memory expediently as rewritable memory, for example as EPROM, designed and contains at least the operating system the communication unit, but preferably the whole Software.
  • the pump unit which is also preferably a digital control is expediently via the line bus of the pump control connected to the communication unit, the communication preferably via a serial RS-485 interface that is made other technical fields of application is well known and therefore it is not described in detail here.
  • the communication unit is such that it is a web server includes, because then the control via an external computer it directly over the directly connected digital network or Internet or indirectly via one connected to the digital network Router from almost anywhere with an internet browser is controllable.
  • This software / hardware equipment enables to access the communication unit directly from the Internet and the operating values made available via the sensor system query and / or intervene in the control of the unit.
  • Within the web server is then expediently a corresponding one Web homepage stored as well as a WAP homepage so that the Communication unit not only by means of a computer via the Internet, but also, for example, using a mobile phone after WAP standard is controllable. This way, even in private Area very simple and flexible control options provided that are practically worldwide via the GSM network or another Radio network can be handled.
  • the communication unit can, if it is advantageous, a connection for communication with at least one other external device has appropriate communication for any other form electrical devices. For example, via an external connection a temperature sensor in the house or any other sensor be connected. But active devices, such as the control of a refrigerator or stove, a garden pump, control of house lighting or any other Devices via this external connection with the digital communication unit connected and so in this way over a digital network and / or controlled via the Internet.
  • the pump unit in particular its digital control system should be designed that they automatically move into a local via the digital communication unit Network or even dials directly into the Internet to access predetermined ones Query addresses by downloading data, which in turn can be used for pump control.
  • a data query can also be done for other units via the external connection are connected to the communication unit. That way it is possible, for example, that the pump control is dependent on the Future weather data (weather forecast) available on the Internet is controllable, so that an intelligent regulation is possible, which also events that are predictable in the future are taken into account.
  • a time query via the Internet which is automatic the internal clock is adjusted or replaced and for the summer / winter time changeover ensures or controls the night setback of the heating system.
  • Data from the electricity supplier can also be queried here throttling the drive power during peak times, for example.
  • the size is an essential criterion in the construction of the invention Communication unit.
  • the one described below digital communication unit can be used using the nowadays usual discrete components on a single board in less than cigarette pack size be set up so that they are in the terminal box or another housing connected to the unit housing can be integrated.
  • the communication unit can also be built the pump unit are designed as a unit.
  • the digital communication unit can be installed in the pump unit itself also like a plug-in power supply at the end of a connecting cable or integrated into the line in the manner of a filter be, e.g. B. in a small housing.
  • the digital communication unit 1 has an interface 2, which the the digital pump control to the communication unit 1 Data as well as in the opposite direction so that communication via a digital line bus 3 from or to the digital Pump / motor control is possible.
  • One serves as the interface modified RS-485 interface, as used in the pump units of the applicant, if digital control is provided, general use finds.
  • the interface 2 is connected to a microprocessor 4, which controls the entire data link of unit 1.
  • the Microprocessor is connected to a dynamic memory 5 (DRAM), which is used for the intermediate storage of data from the microprocessor 4.
  • the microprocessor 5 also has a static memory 6 (permanent memory) in connection, which is designed as an EPROM and the both the operating system and the other software of the communication unit 1 (boot device, flash disc).
  • the microprocessor 4 stands with this embodiment an Ethernet controller 7 in connection, via which the data of the communication unit 1 either for a twisted pair connection 8 or for a coaxial connector 9 can be prepared to over a data line 10 or 11 with a router that connects to the Internet, or with a personal computer with network card or to be connected to a digital network.
  • communication takes place between a PC or an Internet router via an interface 12 (pump user Interface), which is followed by a web server 13.
  • the commands of the web server 13 are sent to a bus driver 15 by means of a script interpreter 14 and thus passed on to the digital control of the pump set.
