Description

The present invention relates to a method for configuring an electromotive pump set with configuration data.

Pump units such as those from the DE201120109497U are known, must be adapted to the hydraulic conditions of their place of use. For this purpose, numerous options are available in the pump electronics of a pump set that are steadily increasing in complexity. Although intelligent pump units are increasingly coming onto the market that can adapt themselves optimally to their operating situation, a good initial configuration nevertheless is expedient since it usually takes several weeks or even months until an intelligent pump set has collected enough information to determine which operation or operating point is the most energy efficient. However, even these pump units can not automatically determine all information, such as their purpose or the pumped medium.

For an optimum setting of the pump unit, therefore, the knowledge of the connected piping network is absolutely necessary. As an example, here are the use of centrifugal pumps in heating systems, drinking water pumps in pressure booster systems for drinking water supply in buildings and sewage pumps for wastewater disposal called. In such applications nowadays electronically controlled and variable speed pumps with frequency converter are in use, which can be operated not only at a constant speed but variable speed. This is usually done according to an adjustable characteristic that has a connection describes between the differential pressure provided by the pump and the volume flow produced by it. For example, so-called Δp-c characteristic curves are known which keep the delivery head constant over the volume flow, Δp-v characteristic curves which define a linear relationship between delivery height and volume flow, or temperature-controlled characteristic curves which define a delivery pressure as a function of an outside temperature or the medium temperature. The area of application of the pump set is decisive for choosing the right or suitable characteristic.

In addition, detailed knowledge of the pipe resistance, any geodetic height, and desired pressure set points in the piping network, i. a certain head, and for a certain volume flow required so that in the case of a heating system all radiators or heating surfaces are sufficiently supplied, and in the case of a drinking water system at all taps sufficient pressure exists.

In addition, modern pump sets offer a variety of activatable functions and settings, as well as various communication interfaces for remote maintenance and remote signaling, which allow integration into a building management system.

If a pipe network with a pump set is first installed and commissioned, all settings and parameter settings must be made on the pump set. This is cumbersome, time consuming and usually requires detailed knowledge of how the configuration is made.

It is therefore an object of the present invention to provide a method and corresponding pump units for this purpose, which enable or allow a configuration of a pump unit in a simple manner, quickly and without technical expertise on the implementation of the configuration of the pump unit.

This object is achieved by a method having the features of claim 1. Advantageous developments are specified in the subclaims.

The core idea of the invention is to use operating data of a second pump unit in order to obtain configuration data therefrom by means of operating data evaluation software, which data are then transferred to the first pump unit to be configured. In addition, configuration data of the second pump set can be transferred directly to the first pump set to be configured. This idea is based on the realization that complete configurations and valuable knowledge about a pipe network in pump units already exist in different situations. Applying this data reduces the time required for the configuration when commissioning a new pump set to a minimum.

A first situation is, for example, a service case. If there is a technical defect in an installed pump unit that requires replacement, the installer must re-make all the settings for the replacement pump. This leads to a correspondingly increased effort and personnel costs. In addition, a documentation of the hydraulic properties of the pipeline network and the pump is usually not or no longer available. Also, the installer of the replacement pump installer is usually not identical to the person who has installed the pump to be replaced. For a matching of the pump to the connected hydraulic network and for an energetically optimal adjustment of the pump would therefore require a re-measurement and calculation of the piping network and its resistances, which is hardly done in practice. Rather, the pump set is configured with universal settings based on assumptions and estimates. It follows that it is not energetically optimal.

A second situation is, for example, the case that pipeline networks are constructed with approximately identical structure and hydraulic properties, as is the case for example in terraced houses or model houses of the same type. Here, several identical pump units would have to be configured identically, which also leads to a correspondingly high cost. This one can minimized according to the invention, however, if knowledge of one or knowledge about another pump unit are used, in the best case simply copied.

Accordingly, the invention proposes a method for configuring a first electromotive pump set with configuration data, in which operating data or operating and configuration data of a second pump set are stored in a non-volatile memory unit of pump electronics of the second pump set, and transmitted from the second pump set to the first pump set be obtained from the operating data of the second pump unit by means of Betriebsdatenauswertesoftware configuration data, which then takes over the first pump unit in the operating software of its pump electronics.

In the case of configuration data, these can be transferred directly to the operating software of the first pump set, so that the first pump set is configured according to the second set of pumps. This corresponds to copying existing configuration data from the other pump set.

In the case of operating data, the implementation of an intermediate step is proposed according to the invention, in which configuration data are obtained from the operating data of the second pump unit by means of operating data evaluation software, which can then take over or take over the first pump set into its operating software. This Betriebsdatenauswertesoftware can both be an integral part of the first pump set as well as represent a separate software solution, for example, on an external computer. Background of this procedure is the fact that just the control technology for pump units, in particular for efficiency and efficiency optimization continuously developed so that the operating data of the second pump unit can always be evaluated according to the latest knowledge to obtain suitable configuration data and then this configuration data for the first Pump unit are available.

Operational data in this context is data that defines operating conditions actually achieved by the second pump set and / or operating points that have passed, i. a lot of historical data characterizing the life story of the second pump set. The operating data may be occurred errors or measured data or calculated or estimated values of physical quantities of the pump set. An operating state can be, for example, the current rotational speed, the electrical power consumption, the applied differential pressure or the delivered volume flow of the pump set. An operating point can be described, for example, by the two hydraulic variables volume flow and delivery head (differential pressure), as is usually the case in a so-called HQ diagram. By means of a Betriebsdatenauswertesoftware can be determined from the operating data, for example, in which modes, which operating areas, along which characteristics a pump unit worked and what demands the hydraulic network has made to the pump unit, so that another pump unit, which are now connected to the hydraulic network should be optimally set up on this network. This is done by the operating data evaluation software evaluates the operating data and generates configuration data from them, which then stores the first pump unit for its control and / or regulation in its operating software.

For the purposes of the present invention, configuration data is understood as meaning data which can be given to a pump set, i. are adjustable and affect the pump unit in its operation, in particular to adjust the operation to a specific operating environment. The configuration data are preferably parameter value settings and / or at least one function setting of the first pump set.

The non-volatile memory unit is a work or operating memory, which is usually permanently integrated in a pump electronics, on which the operating software and possibly further data can be stored, additional physical read-only memory which can permanently store stored data. According to the invention, the configuration and / or operating data are stored from the working or operating memory in this additional memory unit.

This can for example be done once during commissioning of the second pump set, i. immediately after the pump set has been configured, which of course only relates to configuration data, as there are no operating data at this time. Alternatively, the storage of the configuration and / or operating data on the memory unit after some time after commissioning during operation can take place. This can also be the case once, for example, as soon as all configuration data is available, or repeated, in particular at certain fixed times or periodically, so that always current configuration and / or operating data are stored. This takes into account in particular the case that the pump unit is self-learning and seeks its optimal operation setting, for example, in terms of low power consumption itself. It may be, for example, that a previously set control characteristic is replaced by a more energy-efficient control characteristic. If this is the case, the configuration and / or operating data can be updated or supplemented during the next storage. The update can be done by completely overwriting. Alternatively, only those configuration data that have changed can be overwritten.

In addition to the configuration and / or operating data, any further data from the second pump unit can also be taken over into the first pump unit by means of the method according to the invention, for example information about the second pump unit such as its type or the version of the operating software. Such information may be important in a detailed fault analysis and provide valuable insight into failures in the hydraulic system.

According to a first variant, the transmission of the configuration and / or operating data from the second pump unit to the first pump unit can be done manually. For this purpose, the memory unit may be a memory module removably inserted into the second pump unit, which memory module is inserted from the second pump unit is transported to the first pump unit and pluggable connected to the pump electronics of the first pump unit. By inserting the memory module in the first pump unit, it is connected electrically and communication technology with the pump electronics.

Ideally, the first pump unit then reads the configuration and / or operating data from the memory module and stores it for controlling and / or regulating its drive unit in an operating or working memory of its pump electronics. In the case of the configuration data, this takes place directly, in the case of the operating data indirectly, since here an evaluation of the operating data is first carried out, which leads to obtaining suitable configuration data for the first pump set. These obtained configuration data are then stored by the first pump unit for controlling and / or regulating its drive unit in the operating or working memory of its pump electronics. The storage and / or evaluation of the operating data can be done automatically as soon as the memory module is plugged in, or by manually activating a corresponding transmission procedure.

To realize the first embodiment variant, the pump electronics of the first and second pump unit can each have at least one slot in order to connect a memory module to the pump electronics electrically and in terms of communication technology.

It is therefore proposed according to the invention, a pump unit in particular for carrying out the method according to the invention with an electric motor drive unit and a pump electronics for controlling and / or regulating the drive unit, wherein the pump electronics has a slot with a removable plug-in memory module to the memory module electrically and communication technology to connect the pump electronics. As far as this pump unit forms the second pump unit, this is set up to store operating data or operating data determined during its operation and additionally to store configuration data from its operating software onto the memory module. As far as this pump unit forms the first pump set, this is set up, operating data or operating and Load configuration data from the memory module and take over in his pump electronics, especially in the case of configuration data directly into its operating software or in the case of operating data from these by means of Betriebsdatenauswertesoftware to gain configuration data and store them in a memory or working memory of his pump electronics ,

The slot or the memory module are preferably accessible from outside the pump electronics, so that the housing of the pump electronics does not need to be opened. This facilitates the insertion or removal of the memory module and prevents live parts of the pump electronics are touched inside the housing. In this case, it may nevertheless be provided that the slot and / or the memory module can be closed by a removable cover, in particular sealed, in order to protect the slot or the memory module from protection and, if necessary, from moisture.

The memory module is preferably a digital storage medium, in particular according to the flash memory technology. For example, it may be a SD card (Secure Digital Memory Card), a MMC card (Multimedia Card) or a SIM card (Subscriber Identity Module). The memory module may have any format, for example, the size of the classic SD, MMC and SIM card, or be designed as a mini, micro or nano card. Alternatively, it can also be designed as a USB memory stick (Universal Serial Bus). The storage media mentioned are well known, so that no further details are given. They are sturdy and easy to handle. USB memory sticks, in particular, can be assumed to be a type of memory available for years.

According to the storage medium used, the slot of the first and second pump unit is designed so that it can mechanically receive the corresponding storage medium and electrically contact. To connect a USB memory stick, the slot can be configured accordingly as a USB socket. This has the advantage that in principle also an external hard drive can be connected to the pump set. It should be noted that there may also be two or more slots that can accommodate different storage media.

According to a second variant, the transmission of the configuration and / or operating data from the second pump unit to the first pump unit can be carried out by radio.

For this purpose, it can preferably be provided that an RFID transponder (Radio Frequency Identification) of the second pump set reads out the configuration and / or operating data from the memory unit and transmits it by radio.

For this purpose, a pump unit with an electromotive drive unit and a pump electronics for controlling and / or regulating the drive unit with a non-volatile memory unit is proposed which has stored operating data or operating and configuration data in the memory unit, the pump electronics comprising an RFID transponder which can read out the memory unit and transmit the configuration and / or operating data by radio. In this case, the transponder may be active, preferably passive, in order not to be energized for the reading.

Because the use of passive RFID for radio transmission of the configuration and / or operating data has the advantage that the data can still be read out of the second pump unit, if this is no longer operable due to a defect, especially de-energized or completely off that also the RFID transponder can not be supplied with electricity by the pump unit. Because with the passive RFID technology an existing in the RFID transponder surface antenna from an electromagnetic field generates a voltage for the supply of a microchip, which can read a memory and the data via the surface antenna is able to emit again.

Advantageously, the non-volatile memory unit is an integral part of the RFID transponder. Since RFID transponders are equipped with an integrated memory unit as standard, it is therefore not necessary to use the non-volatile ones Storage unit forming additional physical electronic component for storing the configuration and / or operating data provided in the pump electronics. Rather, the storage can be done directly in the memory of the RFID transponder.

As already mentioned, an electromagnetic field is required to read a passive RFID transponder. This can be broadcast for example by means of an external mobile reader. It can then be provided that the mobile RFID reader receives the transmitted configuration and / or operating data and forwards them to the first pump unit which then receives them and stores them in an operating or working memory of its pump electronics for controlling and / or regulating its drive unit , The configuration data can be used directly for the control and / or regulation of the drive unit, in the case of the operating data, this is done indirectly, since initially their evaluation for the purpose of obtaining configuration data is required.

An external reading device has the advantage that the forwarding of the configuration and / or operating data to the first pump set can take place in any way, for example also by radio or by cable. Any technology can be used for the radio transmission, for example also RFID, NFC (Near Field Communication), WLAN (Wireless Local Area Network), Bluetooth or Irda (Infrared Transmission). Also for wired transmission can use any technology, such as a network connection to TCP / IP, a USB connection, a LON or CAN bus connection or a serial connection such as the RS-232 type. Consequently, in order to load the configuration and / or operating data into the first pump set, one of the mentioned communication interfaces, which are generally present, can be used.

Alternatively, the electromagnetic field can be emitted by the first pump unit, in particular its pump electronics. For this purpose, in the first pump unit or in the pump electronics, an RFID reader may be present, which generates the electromagnetic field and the second Pump unit re-transmitted configuration and / or operating data receives, the pump electronics is configured to evaluate received operating data to obtain suitable configuration data and store this configuration data obtained for controlling and / or regulating its drive unit in the memory unit of its pump electronics. This has the advantage that no separate reader is needed. It is sufficient to bring the second pump unit or its pump electronics in the vicinity of the first pump unit or its pump electronics, ie to bring the RFID transponder in the electromagnetic field of the RFID reader to make the transfer of the configuration data.

According to a third variant, the transmission of the configuration and / or operating data from the second pump unit to the first pump unit can be made optically by means of a code. This can be done in such a way that the data are displayed encrypted on a controllable display of the pump electronics of the second pump unit. The code is then read and provided encrypted or decrypted to the first pump set. The configuration and / or operating data are then stored after its provision on a pump unit for controlling and / or regulating its drive unit in an operating or working memory of its pump electronics. Again, the configuration data can be used directly, the operating data indirectly for controlling and / or regulating the drive unit.

The configuration and / or operating data can be encrypted by the second pump unit in a character string or in a two-dimensional or multi-dimensional graphic code or be displayed encrypted in this character string or this graphic code.

The string may be a sequence of alphanumeric characters and / or symbols. A string has the advantage that it can be read without a reader. The configuration and / or operating data, which can be extensive, are thereby mapped to the comparatively few characters and / or symbols of the character string, as a result of which less data is to be transmitted than in the case of uncoded configuration and / or operating data. The String can have any finite number of characters and / or symbols. The length may be dependent on the amount of configuration and / or operating data to be coded.

The graphical code may be a one-dimensional dot or bar code (bar code) or a two-dimensional dot code, also called matrix code, such as a QR code. Also multi-dimensional codes consisting of nested bar and / or matrix codes are possible. They can encode a variety of information and contain redundancy and checksums to reduce the susceptibility to errors and are therefore particularly safe for the error-free transmission of data from one pump set to another pump set.

The reading of the string can be done by a user who then manually enters the string on the first pump set. This can be done with the aid of a control element, in particular a control knob, wherein the input characters are preferably displayed during their input on a display of the first pump unit.

Alternatively, the transmission of the graphic code between the pump units can preferably take place by optical reading by means of a mobile optical code reading device. The reading device can then provide the configuration and / or operating data to the pump electronics of the first pump unit.

The use of a code reader has the advantage that the reading can be done by machine, so that no errors in the acquisition of configuration and / or operating data, in particular reading-related errors can occur. A further advantage is that the forwarding of the configuration and / or operating data to a pump unit can take place in any way, for example by radio or by cable. For the radio transmission, any known technology can be used, for example also RFID, NFC (Near Field Communication), WLAN (Wireless Local Area Network), Bluetooth or infrared transmission. Also to Wired transmission can be any technology, such as a network connection to TCP / IP, a USB connection, a LON or CAN bus connection or a serial connection, for example, to RS-232. Consequently, in order to load the configuration and / or operating data into the pump set, one of the communication interfaces, which are generally available, can be used.

The operating data can be decoded by the first pump set or in the reader. It is also possible that the reading device and the first pump set each perform a partial decoding.

To carry out the transmission of the configuration and / or operating data by optical means as coded information is proposed as a second pump unit according to the invention a pump unit with an electric motor drive unit and a pump electronics for controlling and / or regulating the drive unit with a non-volatile memory unit, wherein the Pump electronics has a coding unit for encoding operating data or operating and configuration data to a string and / or a graphic code and a display for displaying the character string or the graphic code, wherein the coded configuration and / or operating data in the memory unit can be stored.

In a corresponding manner, a pump unit with an electromotive drive unit and a pump electronics for controlling and / or regulating the drive unit with an operating memory is proposed as the first pump unit, wherein the pump electronics has a decoding unit for decoding coded configuration and / or operating data, wherein the pump electronics to is set up to evaluate the decoded operating data for obtaining suitable configuration data and to store these obtained configuration data for controlling and / or regulating the drive unit in the operating memory.

Further features and advantages of the method according to the invention and the pump units according to the invention are explained in more detail below with reference to three exemplary embodiments and the attached figures. Show it:

FIG. 1:

Transmission of configuration data by plugging a memory module

FIG. 2:

Transmission of configuration data by radio reading

FIG. 3:

Transmission of configuration data by optical readout

FIG. 1 shows on the right a first pump unit 1b and left a second pump unit 1b. The first pump unit 1b is about to be commissioned and requires a configuration setting parameter values and functions. The second pump unit 1a was already in operation and therefore has a complete configuration as well as operating data characterizing its past operating conditions and operating points. The first and the second pump unit 1a, 1b are structurally the same or at least similar in that the first pump unit 1b can replace the second pump unit 1a in the application in which it was operated.

Both pump units 1a, 1b have an electromotive drive unit 2a, 2b and pump electronics 3a, 3b for controlling and / or regulating the respective drive unit 2a, 2b. The pump electronics 3a, 3b each have a slot with a removable insertable memory module 6, for example in the form of an SD card. In the pump electronics 3a of the second pump unit 1a, such a memory module 6 is inserted. The slot is electrically and communicatively connected to a microprocessor 5a, which takes over the data transmission and data processing in the pump electronics 3a. Since the memory module 6 is inserted, this is also connected to the microprocessor 5a. In addition, the pump electronics 3a a non-volatile memory 4a, are stored in the operating data and in particular the operating software including configuration data. This operating memory 4a is also communicatively connected to the microprocessor 5a.

The first pump unit 1b has the same components. Its pump electronics 3b also has a slot for the memory module 6 and is electrically and communicatively connected to a microprocessor 5b, which takes over the data transmission and data processing in the pump electronics 3b. In addition, the pump electronics 3b has a non-volatile operating memory 4b for operating data and configuration data of the operating software. This operating memory 4a is also communicatively connected to the microprocessor 5a.

The second pump unit 1a is set up, during operation, to provide operating and configuration data from its operating software, i. in particular from the operating memory 4a to the memory module 6 to store at regular intervals. This configuration data includes all parameter value and function settings. The operating data comprise a history of operating points that have been run through, possibly measured values of physical quantities of the pump set and / or error information.

The memory module 6 is accessible from the outside, so that no housing of the pump electronics 3a needs to be opened. Because of this easy accessibility, it can be easily removed from the second pump unit 1a and plugged into the slot of the pump electronics 3b of the first pump unit 1b.

If the second pump unit 1a is defective and has to be replaced by the first pump unit 1b, the memory module 6 with the configuration data stored there is pulled out of the slot of the pump electronics 3a of the second pump unit 1a and inserted into the corresponding slot of the pump electronics 3b of the second pump unit 1b. This is illustrated by the dashed arrow. The first pump unit now loads the configuration and operating data from the inserted memory module 6 and takes it into its pump electronics by being stored by the microcomputer 5b in the operating memory 4b. Configuration data is transferred directly to the operating software. The operating data are first evaluated by means of evaluation software, wherein from the operating data information about a suitable configuration of the first pump unit, for example, one for the hydraulic network to which the first pump unit is to be connected. optimal characteristic can be determined. The configuration is then transferred to the operating software of the first pump set.

According to this first embodiment variant, the transmission of the configuration and operating data from the second pump unit 1a to the first pump unit 1b consequently takes place manually by means of a transported physical one Storage medium that carries the configuration and operating data and is plugged from a slot of the second pump set into a slot of the first pump set.

FIG. 2 shows an alternative embodiment for the transmission of the configuration and operating data from the second pump unit 1a to the first pump unit 1b, in which the reading of the data is carried out by radio. Hereinafter, only those components and properties of the two pump units 1a, 1b are addressed, in which they differ from the first embodiment variant.

According to the second embodiment, the second pump unit 1a has a passive RFID transponder 7a, wherein the non-volatile memory unit 6a is part of this RFID transponder 7a. The memory unit 6a can accordingly be read out by the RFID transponder 7a as soon as an electromagnetic field passes through the RFID transponder 7a.

To generate the electromagnetic field and to read the RFID transponder 7a or its memory unit 6a, a mobile RFID reader 8 is used. This receives the configuration and operating data sent by the RFID transponder 7a and forwards them by any means to an interface 9 of the first pump unit 1b, which is expressed by the dashed arrow. This can be wired or by radio, so that the interface 9 can be configured either as a radio receiver or as a socket for a cable, the interface 9 is connected within the pump electronics 3b to the microcomputer 5b, so that the configuration and operating data transmitted to this and can be stored by it in the operating memory 4b.

The first pump unit 1b also has a passive RFID transponder 7b with a non-volatile integrated memory unit 6b into which the microcomputer 5b can store configuration and operating data, so that the first pump unit also offers the possibility of configuration and operating data RFID read out.

FIG. 3 shows a further alternative embodiment for the transmission of the configuration and operating data from the second pump unit 1a to the first pump unit 1b, wherein the readout of the data takes place optically. Hereinafter, only those components and properties of the two pump units 1a, 1b are addressed in which they differ from the first embodiment variant.

According to this third embodiment, the second pump unit has a display 10a with a display 13a. The non-volatile memory unit 6a into which the configuration and operating data are stored is here part of the display control of the display 10a.

Furthermore, the pump electronics 3a of the second pump unit 1a has an encoding unit for coding the configuration and operating data to a character string 14 and / or to a graphic code. The coding unit may be a separate electronic unit within the pump electronics 3a or be part of the microcomputer 5a, as in the third embodiment in FIG. 3 the case is. The coding unit here encodes the configuration and operating data and stores them in this coded form in the memory unit 6a, so that they can be displayed immediately on the display 13 a. In the third embodiment, this takes place in the form of an alphanumeric character string 14.

The character string 14 can be read off the display 13a, in particular by a user, who then has to input this on the first pump unit 1b. This can be done via an input means 15b, in particular a control knob, which is connected to the microcomputer 5b. Also, the first pump unit 1b has a display 10b with a display 13b, on which the successively entered characters of the string can be displayed. It should be noted that the second pump unit also has an input means 15a, which also makes it possible to enter a character string there.

As an alternative to the optical reading of the display 13a by a user, a mobile optical reader 11 can be used that via a code scanner 12 or a CCD camera 12 has. A mobile reading device 11 is particularly suitable when the configuration and operating data are encoded in a graphic code and displayed on the display 13a, since in this case it is no longer possible to human read the encoded data.

FIG. 3 thus shows an alternative variant for the optical reading of the coded configuration and operating data, in which these are displayed as a graphic code on the display 13a of the display 10a. If the optical reader 11 has read in the code, it can decode the configuration and operating data and send it to the pump electronics 3b of the first pump unit 1b in decoded form. Alternatively, the decoding of the data within the pump electronics 3b of the first pump unit 1b can take place, wherein the mobile reading device 11 then electrically conducts the optically detected data and / or electromagnetically to an interface 9 of the pump electronics 3b of the first pump unit 1b.

According to this variant, the first pump unit 1b has a decoding unit, which may be a separate electronic unit of the pump electronics 3b or may be part of the microcomputer 5b. The decoding unit then decodes the encoded data accordingly, which are then stored by the microcomputer 5b in the operating memory 4b. If the decoding has already taken place in the reader 11, the microcomputer 5b can store the decoded configuration and operating data directly into the operating memory 4b.

All of these variants make it possible to easily transfer configuration and / or operating data of a second pump unit to a first pump unit, so that only a minimal amount of time and no special knowledge about the configuration of the pump unit 1b is required.
