  • the invention relates to a method for monitoring an electronically controlled centrifugal pump of a hydraulic system, the operation of which can be determined by a changeable operating configuration.
  • the invention relates to a system for executing the method and a computer program that can be loaded onto the hand-held device and has commands which, when executed on the hand-held device, cause the hand-held device to carry out those procedural steps that are provided as part of the method according to the invention, carried out by the hand-held device to become.
  • the invention also relates to a computer-readable storage medium with the computer program.
  • US 2017/0211285 A1 is a system and a method for providing network connections between and for remote monitoring, optimization and control of pool and spa devices, such device also being a pump that can be controlled via the Internet.
  • the pump is set up to determine system efficiency and to inform an external body if there is a deviation from a specified value.
  • the European patent application EP 3242033 A1 teaches you to check whether an initial configuration has already been carried out on a booster system. For this purpose, after 72 hours, for example, the pump electronics is checked to see whether the storage date of a specific file with factory setting parameters has been changed in the meantime. If this is not the case, a message will be issued and a service will be informed.
  • centrifugal pumps used to run uncontrolled at a single fixed speed, speed-controlled centrifugal pumps have been in use for a long time, trying to adapt their pumping performance, in particular their operating point determined by the delivery pressure and flow rate, to the needs of the pump Adapt the hydraulic system to save energy.

  • the controller must be parameterized with regard to its control parameters and, in particular, a setpoint must also be specified for the control. In any case, at least the latter must be carried out depending on the hydraulic system in which the centrifugal pump is integrated, such as a heating, cooling or drinking water supply system for hot or cold water circulation, for accumulator loading or pressure increase.
  • Centrifugal pumps now offer a large selection of different operating modes, especially control modes, in order to meet their system-specific purpose.
  • the most common types of control are constant differential pressure ( ⁇ p-c) or variable differential pressure ( ⁇ p-v), especially proportional pressure control.
  • Temperature control methods are also known, such as control to a constant target temperature (cT) or control to a specific difference temperature ( ⁇ T-c), such as those used, for example, in heating systems using condensing technology or systems with heat exchangers or hydraulic switches.
  • Another operating mode for example, is operation at constant speed, which can also often be selected in centrifugal pumps.
  • Each of these control types offers different setting options, in particular the selection of a specific control characteristic from a large number of different control characteristics.
  • centrifugal pump in a hydraulic system requires a specific setting or adaptation of its operating configuration to its operating purpose or to the hydraulic system. It is the task of a specialist, for example the installer, to carry out this configuration of the centrifugal pumps correctly during their installation or when commissioning the hydraulic systems, which usually requires knowledge of the physical control relationships on the one hand, the pump setting options (HQ pump map) and the hydraulic systems , in which the centrifugal pump is installed is, on the other hand, requires. Ultimately, the configuration can be changed again at any later point in time.
  • centrifugal pump or pumps After the centrifugal pump or pumps have been installed and commissioned, at least in large systems with several tens or even several hundred pumps, such as those found in airport buildings, exhibition halls but also in many public buildings such as hospitals, schools, hotels, office buildings, etc., a regular checks of functionality, be it in the simplest case, for example through a visual inspection. Modern pump units use an indicator or a pump display to show whether they are OK or have detected a malfunction.
  • the object of the invention is to provide a method and a computer program that enables the person skilled in the art, an installer or maintenance technician, to quickly and easily recognize whether a centrifugal pump has been adjusted since the last operating configuration, i.e. the configuration has been changed.

  • This change notice is then an indication to the specialist that the operating configuration on the centrifugal pump has been changed. He can then check them in detail and correct them if necessary.
  • Another advantage of the process is that every change in the operating configuration does not have to be documented in either the pump or the handheld device. There is no need to save a change history, for example in the form of a logbook. This saves storage space and the process for detecting a change in the operating configuration is particularly simple.
  • a centrifugal pump is understood to mean a device consisting at least of a pump unit for conveying a liquid, a drive unit in the form of an electric motor that drives the pump unit, and pump electronics for controlling and / or regulating the electric motor, these being structurally combined or only can work together functionally.

This advantage is particularly noticeable when there are a large number of centrifugal pumps to be checked and the larger this number is, the more noticeable it is.
  • the centrifugal pump can be set up to broadcast the configuration information repeatedly, in particular periodically, as a broadcast signal, with the handheld device receiving this broadcast signal in an activated listening mode.

Although such a value does not identify the operating configuration compared to the operating configurations of other centrifugal pumps, since many centrifugal pumps will probably work with the same target delivery head, one operating parameter or one operating setting is sufficient to be able to carry out a before-and-after comparison in the sense of the invention.
  • two, three or more operating parameters or operating settings can also be transmitted from the centrifugal pump to the handheld device or the server.
  • the centrifugal pump can transmit all or part of its current operating configuration to the mobile handheld device or the server. This or this essentially forms a fingerprint of the pump.

The handheld device therefore knows which centrifugal pump the received configuration identifier comes from.
  • a directed communication connection point-to-point connection
  • Fig. 6 The scenario shown is taken into account, whereby the centrifugal pump uses the broadcast of a pump identifier for its identification.
  • the scenario is analogous Fig. 5 assumes that a checksum is used as the configuration identifier.
  • the scenario in Fig. 6 begins again with the pre-configuration of the centrifugal pump in the software application of the hand-held device, with the operating configuration defined in this process being saved under a pump identifier of the centrifugal pump in the hand-held device, step S16.
  • the pump identifier can be assigned by the software application, or was previously transmitted to the handheld device by the unconfigured centrifugal pump, or alternatively entered manually by an installer.
  • the operating configuration and its are then transferred Storage in the centrifugal pump, step S26, whereby the centrifugal pump also adjusts itself according to the configuration.
  • the centrifugal pump After configuration, the centrifugal pump repeatedly, in particular periodically, broadcasts its pump identifier and the current configuration identifier that it determines each time as a broadcast signal, step S66.
  • the handset 4 which is in listening mode, receives the pump identifier and the configuration identifier, step S76. It now determines the checksum as a configuration identifier from the operating configuration stored in it associated with the received pump identifier, step S86.
  • the received checksum of the centrifugal pump is then compared with the checksum determined by the handheld device 4, step S96. If they match, the process is ended, step S106. If there is no match, a change notice 7 is output on the handheld device 4, step S116.
  • the special thing about the in Fig. 6 The scenario presented is analogous to the scenario in Fig. 4 the fact that there is or does not need to be a directed communication connection (point-to-point connection) between the handheld device and the centrifugal pump during operational testing or maintenance.
  • the transmission of the pump identification and the configuration identification is not receiver-specific, ie it is not directed to a specific handheld device. Broadcasting as a broadcast signal is possible with the short-range communication technology Bluetooth 5.0, more precisely with the Bluetooth Low Energy (BLE) protocol stack defined therein, which is also preferred.
  • the centrifugal pumps 5a-5f are each equipped with a radio module, here in the form of a Bluetooth ® radio module.
  • the trigger for the broadcast of the centrifugal pump can also be the receipt of a query from the handheld device 4, similar to that in step S65 in Fig. 5 .
  • a query can be preceded by step S66, with the repetition of the broadcast then being omitted in step S66, since the centrifugal pump only broadcasts the pump and configuration identifier, preferably once, when the query is received.
  • the broadcast must also be repeated two or three times to ensure that the handset is receiving the broadcast signals.
  • the query of the configuration identifier by the handheld device can also be carried out in a receiver-unspecific manner.
  • centrifugal pump 5a-5f in Fig. 1 their configuration identifier, which the handset 4 also receives.
  • the handheld device can use the pump identifier to assign which configuration identifier comes from which pump.
  • the pump identifier and/or the configuration identifier are transmitted in encrypted form. This is done because a common key is known to the centrifugal pumps 5a-5f and the handheld device or the software application, which is used to encrypt the data.
  • the pump identifier can be any alphanumeric identifier that uniquely identifies the centrifugal pump within the group or even globally, such as a centrifugal pump serial number or an SAP number.
  • the globally unique Bluetooth address of the radio module is used as the pump identifier.
  • Another network technical address, such as a MAC address, can also be used here.
  • the centrifugal pump can carry out a one-time calculation and storage and then provide this in response to the query from the handheld device.
  • the handheld device can carry out a one-time calculation and storage and then load and use this for comparison with the checksum of the centrifugal pump.
  • both the centrifugal pump and the handheld device can operate in this way.
  • FIG. 7 A scenario in which an arbitrary configuration identifier is agreed between the devices when configuring the centrifugal pump is in Fig. 7 shown.
  • a configuration identifier is specified, step S17. This can be a checksum, a timestamp, or any operational configuration name.
  • the operating configuration and the configuration identifier are then stored in the handheld device 4 and then transmitted to the centrifugal pump, which in turn stores them, step S27.
  • the centrifugal pump adjusts itself according to the operating configuration.
  • the current configuration identifier of the centrifugal pump is queried, step S67, whereupon the centrifugal pump transmits the last configuration identifier it stored, step S77.
  • the handset 4 receives the configuration identifier, step S87, and calls up the configuration identifier it has stored.
  • the received configuration identifier of the centrifugal pump is then compared with the configuration identifier stored in the handheld device 4, step S107. If they match, the process is ended, step S117. If there is no match, a change notice 7 is output on the handheld device 4, step S127.
  • centrifugal pump instead of querying the centrifugal pump or instead of non-directed querying of all centrifugal pumps as a trigger for the centrifugal pump to transmit its current configuration identifier, it can be provided that the centrifugal pump repeatedly broadcasts the configuration identifier as a broadcast signal. All circuit pumps that are being monitored can also do this. Such a scenario is in Fig. 8 shown.
  • Fig. 8 is different from the scenario described in Fig. 7 is shown, only in that instead of querying the current configuration identifier of the centrifugal pump in step S67 and transmitting the configuration identifier in response thereto in step S77, the broadcasting of the pump identifier and the current configuration identifier by the centrifugal pump as a broadcast signal occurs. This takes place without being asked, so that the handset only has to be in listening mode in order to hear or receive and evaluate the radio signals.
  • the handheld device receives the pump identifier and configuration identifier, step S88, and then calls up the configuration identifier stored in it based on the pump identifier that was also received, step S98.
  • step S88 the handheld device receives the pump identifier and configuration identifier
  • step S98 the configuration identifier stored in it based on the pump identifier that was also received.
  • step S108 the received configuration identifier of the centrifugal pump is compared with the configuration identifier stored in the handheld device 4, step S108. If they match, the process is ended, step S118. If there is no match, a change notice 7 is output on the handheld device 4, step S128.
  • FIG. 9 An alternative scenario in which the centrifugal pump repeatedly broadcasts its current configuration identifier as a broadcast signal is in Fig. 9 shown.
  • This scenario is particularly useful when the configuration identifier is a timestamp, although it can also be a checksum or any name for the operational configuration.
  • the method again assumes that the centrifugal pump is pre-configured in the software application of the handheld device 4.
  • the operating configuration thus defined is saved in the handheld device, step S19.
  • the operating configuration is then transferred and stored in the centrifugal pump.
  • a configuration identifier is created by the centrifugal pump, step S29. This configuration identifier is then transmitted to the handset 4, step S39, which receives it and stores it, step S49.
  • the centrifugal pump periodically broadcasts its pump identifier and its current configuration identifier as a broadcast signal, step S59.
  • the hand-held device 4 is put into listening mode in order to receive and evaluate the radio signals. This can be done, for example, by starting the software application on the handheld device 4.
  • the handheld device 4 receives the pump identifier and configuration identifier, step S79, calls up the configuration identifier stored in the handheld device 4 based on the pump identifier, step S89, compares this with the received configuration identifier of the centrifugal pump, step S99. If there is a match, the process is ended, step S109. If there is no match, a change notice 7 is output in the handset 4, step S119.
  • Bluetooth is preferred as the technology for short-range communication in the scenarios.
  • the pump identifier and the configuration identifier are broadcast as a broadcast signal in a so-called advertising channel, which is defined in the Bluetooth Low Energy (BLE) protocol stack of the Bluetooth 5.0 standard. No pairing of the devices is required for the transmission.
  • BLE Bluetooth Low Energy
  • the pump identifier can be the serial number of the centrifugal pump, alternatively the Bluetooth address of the Bluetooth radio module or any other communication address such as a MAC address.
  • the handheld devices 4 During on-site use, the handheld devices 4 have no Internet connection, but after use the handheld devices are synchronized via an Internet connection.
  • a configuration identifier in the form of a timestamp (ZLE) generated by the pump is used.
  • the ZLE is constantly sent repeatedly as a broadcast signal, for example via the Bluetooth Advertising Channel. All ZLE are collected by the software application of the handheld device of the respective employee A, B, C of company X when he is on site and uploaded to a central server with an existing internet connection. The data that applies personally to the employee (see “A-Part” explained below) is compared with a global part and, if new, is transferred to the global part. Conversely, ZLE are also transferred from the server to the employees' handheld devices ("synchronization of server and handheld devices"). This means that the information that various employees of a company collect merged. In addition to the list on the central server, there are copies on all handheld devices. An example of a list held on employee A's handset is shown in Fig. 11 shown.
  • the software application can combine these events into one event, for example by defining that there can only be 1 visit per day. It is also conceivable to use GPS to detect that the employee is moving away from the location.
  • FIG. 12 A flowchart of a scenario under synchronization with a server is shown in Fig. 12.
  • the solution makes it possible to register changes via the pump HMI as well as changes via the software application. This works because every change (including via the pump HMI) is communicated to the software application within seconds via the Bluetooth advertising channel. The software application then synchronizes this information to the server when there is an Internet connection. The only requirement is that the handheld device is within radio range of the pump and the software application is activated when any change is made.
  • the technical requirement is that the pump constantly sends the ZLE or something similar repeatedly and that the employees always carry a hand-held device with an activated software application with them.
