Problems solved by technology

This approach has been proven effective in principle, but has some systemic shortcomings in terms of authorization security
Since the operating device is also wirelessly connected to the device, if it communicates directly or indirectly via a server, it cannot exclude unauthorized access with the required security

Embodiment Construction

[0041] exist figure 1 In , a pump unit 1 is shown comprising three parallel centrifugal pumps 2 which are each driven by an electric motor 3 with a corresponding frequency converter 4 and which are operated or coordinated by a central electronic controller 5 . Here, the electronic controller 5 is arranged as an external component, it being understood that this electronic controller can also be the control electronics of the frequency converter 4 if for example the centrifugal pump 2 with the connected electric motor 3 is operated alone. part of the device.

[0042] The shown pump unit feeds from the suction line 6 into the pressure line 7 and can be part of a waste water or fresh water system. The electronic control unit 5 has a GPS receiver, which receives data from satellites in a known manner and determines the position of the pump unit 1 from differences in its operating times. The electronic controller 5 also has a mobile communication receiver, which receives at least ...

Abstract

The method for authorising a data communication between an electronically controlled pump unit (1) and an operator control unit (12) configured for wireless communication with the pump unit (1) operates using an external data-network-connected server (10). In a 1st step, the installation location data (GPS 1) of the pump unit (1) are transmitted to the server (10) via the data network. An identification code of the operator control unit (12) and the location data (GPS2+3) of the operator control unit (12) are then transmitted to the server via the data network. The server checks whether the operator control unit (12) is intended for data communication with the pump unit (1) and whether the operator control unit (12) is within a predetermined physical range (A) of the pump unit, after whichthe data communication is enabled or disabled for a time.

Description

technical field [0001] The invention relates to a method for authorizing data communication between an electronically controlled device, in particular an electronically controlled pump assembly, and an operating device, and to a device with control electronics designed to carry out the method Electronically controlled pump unit. Background technique [0002] It is prior art in electronically controlled pump units to set operating parameters and / or operating data after installation or during subsequent maintenance, inspections, etc., in order to run a pump optimally in the desired operating mode and generally energy-optimized or multiple pumps operated by control electronics. This can be achieved by making corresponding settings on the operating panel of the pump, however, this is now advantageously achieved by an operating device which is designed for wireless communication with an electronically controlled device, in particular an electronically controlled pump unit.
