Definitions
- the invention relates to a method for installing a device for monitoring at least one machine with a rotating machine part.
- the monitoring of individual components of a hydraulic system is an important and central topic.
- Various sensors are attached to the hydraulic components to be monitored, such as hydraulic pumps and motors, valves, etc., and measure different operating parameters of the components.
- the measured values must be transmitted to a central computer unit for evaluation and monitoring.
- a gateway is used that communicates wirelessly with the individual sensors and then forwards the measurement data received to the central computer unit.
- this initial problem is solved by a method according to the characteristics of claim 1.
- Advantageous refinements of the method are the subject matter of the dependent claims.
- the invention also relates to a system for carrying out the method according to the invention.
- the machine to be monitored with a rotating part is preferably a hydraulic machine, such as, for example, a hydraulic pump or centrifugal pump.
- a device consisting of a gateway, a sensor unit for recording machine-related data from the machine to be monitored, a transmitter unit with a transmitter antenna for wireless transmission of the measured values recorded by the sensor unit to the gateway and a user terminal device for communication with the Gateway proposed.
- the special feature of the device is that the sensor unit and transmission unit or at least the transmission antenna are physically separate units that can be placed independently of one another on or in the area of the machine to be monitored.
- the transmission unit can be an integral part of the sensor unit.
- the transmitting antenna is designed as a separate component that can be connected to the transmitting unit / sensor unit via a cable connection. This results in a certain flexibility in the arrangement of the transmitting antenna.
- the transmission unit is designed as a structural unit external to the sensor unit.
- the transmitter unit is connected to the sensor unit by cable or other connection (including wireless).
- the transmitting antenna is then either an integral part of the transmitting unit or again as an external component that is connected to the transmitter unit via a cable connection.
- the gateway is installed in the desired position.
- the at least one transmission unit is communicatively coupled to the gateway and then the transmission unit and / or the transmission antenna is positioned on or in the area of the machine to be monitored.
- the communication connection between the gateway and the transmitter unit is preferably set up under optimal conditions, i.e. the transmitter unit is first brought into close proximity to the gateway and only moved to the area of the machine to be monitored after the connection has been successfully established.
- the data transmission begins, preferably from the transmission unit to the gateway.
- at least one communication parameter influencing the transmission quality of the communication path is then determined.
- a subsequent evaluation of the communication parameters allows conclusions to be drawn about the current reception quality.
- a position change instruction for the transmitter location ie the transmitter unit and / or the transmitter antenna, can then be generated.
- This instruction is then displayed for the user by means of the user terminal and / or by the transmission unit itself. This is intended to induce the user to change the current position of the transmission unit or the transmission antenna in such a way that the communication parameters under consideration are optimized and, in the end, the transmission quality is improved.
- the transmitting unit or transmitting antenna is not immediately installed permanently, but initially temporarily positioned at the intended installation site.
- the then triggered data transmission preferably test data, is continuously monitored in order to optimize the transmission quality on the communication path between the transmission unit and the gateway by changing the position of the transmitting unit or the transmitting antenna.
- the generated position change instructions can include a general request to change the position.
- such an instruction can also contain further details for the changes in position, for example in which direction the transmitter is to be moved or how its orientation is to be changed. This gives the user better help for the alignment and positioning of the transmitter unit or transmitter antenna.
- the user is informed as soon as a position with sufficient transmission quality has been found. Only when such an installation has been found by means of the method is the transmitting unit or transmitting antenna permanently installed on or in the area of the component to be monitored. Then send or parallel to it, the sensor unit can then also be permanently installed on the component to be monitored and coupled to the transmitter unit.
- the user can also be presented with a recommendation for action.
- a recommendation for action serves to further increase the transmission quality without or in addition to changing the position.
- position change instructions and / or recommendations for action are signaled to a user terminal and displayed to the user by means of the device.
- a display is preferably done visually, but can also be done acoustically.
- a purely acoustic and / or haptic display is of course also possible.
- a display of the determined communication parameter or the evaluation result is displayed. Examples of communication parameters to be considered are the signal reception level and / or a signal-to-noise ratio and / or a bit error rate.
- the user terminal can be part of the transmission unit or the gateway. Before given, however, is a design of the user terminal as a separate device that communicates with the gateway and exchanges the necessary data for display.
- the use of a mobile user terminal for example in the form of a commercially available tablet, smartphone or other mobile device, is particularly preferred.
- An application installed on the user terminal interacts with the gateway.
- the communication connection between the user terminal and the gateway is radio-based and is preferably based on a WLAN standard and / or Bluetooth standard.
- the evaluation of the at least one communication parameter can preferably take place by comparison with an assigned reference or threshold value. For example, when the threshold value is undershot, it is assumed that communication conditions are inadequate, ie the threshold value represents a corresponding minimum requirement for the respective communication parameter. A comparison with a minimum signal strength for the signal received on the gateway side and / or a minimum is conceivable here Signal-to-noise ratio and / or a maximum bit error rate.
- a graphic preparation of the position change instructions could also be generated in the form of a so-called fleat map and displayed.
- Such a two-dimensional representation gives a good overview of the reception quality over the spatial extent of the system area.
- the use of blink codes, warning tones or applications in the area of augmentedA / virtual reality is also conceivable in order to prepare the instructions and measurement data as clearly as possible for the user.
- the possibility of pronouncing a treatment recommendation relates to a modification of the transmitting and / or receiving unit, according to the advantageous embodiment. It is conceivable that the user is given an indication of the use of a different transmission antenna with a higher antenna gain. In the case of a spatial separation of the sensor unit and the transmitter unit / transmitter antenna, the proposal could also be submitted to use a longer connection cable between the sensor unit and transmitter unit or transmitter antenna in order to be more flexible when positioning the transmitter unit or transmitter antenna.
- the communication between the gateway and the one or more transmission units takes place using mesh network technology.
- a suitable communication protocol is, for example, THREAD.
- the method is repeated before the fixed installation of a transmitting unit / transmitting antenna for all possible sensors and installation points of the industrial plant to be monitored.
- the use of a single transmission unit is sufficient, which is positioned one after the other in the area of the components to be monitored.
- the specified position is either marked manually on the component or corresponding position data is electronically stored in a memory, in particular in connection with metadata describing the installation location.
- an installation plan or sketch can be generated automatically after the process has ended, which clearly shows all installation locations for all components.
- Possible versions of the sensors are used to record temperature or vibration values.
- the transmitting unit and / or transmitting antenna and, if applicable, the separate sensor unit can, for example, be fixed to the component to be monitored in a form-fitting, non-positive or material-locking manner.
- Possible installation points for a sensor unit are the bearing bracket or the drive lantern with Pumps.
- the present invention also relates to a system consisting of at least one gateway, at least one sensor unit, a transmission unit with a transmitting antenna and a user terminal, in particular a mobile user terminal, the system components being configured to carry out the method according to the present invention.
- the corresponding evaluation and evaluation steps are preferably carried out within the gateway or within the transmission unit.
- the gateway or the transmission unit also includes a corresponding memory for storing predefined threshold values and for storing the installation locations determined in conjunction with corresponding metadata.
- the transmission unit can be an integral part of the sensor unit.
- the device comprises an external transmitting antenna which is connected to the transmitting unit by a cable connection.
- the cable connection can be exchanged due to suitable interfaces on the antenna and transmitter unit, in order to replace the connection with a longer cable if necessary.
- the sensor unit and the transmitter unit form separate components which can be detachably connected to one another by means of cabling or also by radio, in particular for signal exchange.
- a necessary energy module for the energy supply of the Sensor unit or the transmitter unit is designed as an external component.
- the integration of the energy module in the transmitter unit is preferred. In the case of the version with an external transmission unit, this can either comprise an integral transmission antenna or it can be connected to an external transmission antenna or be connected by cable.
- sensors that can detect temperatures and / or mechanical vibrations and / or acoustic signals is suitable for monitoring pumps.
- the single figure shows a schematic overview of the device according to the invention for monitoring one or more Flydraulikpumps 60.
- the device comprises a central gateway 10, which is communicatively connected to one or more transmission units 20.
- the transmission unit 20 is exemplified, but any number of transmission units 20 can be integrated into the network.
- the communication between gateway 10 and transmission unit 20 can take place on the basis of the known thread protocol for setting up a mesh network, in which transmission units 20 can communicate both with one another and with gateway unit 10.
- External access to the gateway 10 can take place via a commercially available tablet or other mobile terminal device 30 (user terminal).
- the gateway 10 can be connected to the Internet or a cloud 50 via a further interface.
- the gateway ideally has a mobile radio module which supports at least one of the known mobile radio standards such as 2G, 3G, 4G, 5G or higher, or a cable-bound Ethernet interface.
- an industrial plant with several hydraulic pumps to be monitored separately is to be equipped with the monitoring device.
- the aim is to attach one or more sensors 21 per pump 60, which, for example, can measure the temperature of the pumped medium as well as the occurrence of mechanical vibrations in the area of the bearing bracket.
- the sensors 21 are each connected via a detachable cable connection 23 to an assigned separate transmitter unit 20 which, in addition to the transmitter module and antenna 22 for communication with the gateway 10, also has the energy source for the energetic supply of the transmitter unit 20 and the sensor 21 itself .
- the attachment of the sensors 21 on the bearing bracket of the hydraulic pump 60 can be done magne table, via a screw connection or by gluing using industrial adhesive.
- a careful selection of the appropriate installation location upstream is clearly important. For this reason, the method according to the invention is carried out both before the final fixation of the sensor 21 and the transmission unit 20 in order to find out the best installation location.
- the gateway 10 is first put into operation and access to the gateway 10 is established by means of a mobile terminal device 30.
- an application installed on the terminal 30 is first started, which is used to establish a logical connection with the gateway 10.
- the mobile radio reception of the gateway 10 can then be tested in order to first determine an optimal gateway location for the mobile radio reception, which of course should also be in the vicinity of the transmitter units 20 to be installed, and around the gateway 10 ultimately to be permanently installed in the best location.
- the transmission unit is brought into the vicinity of the gateway 10 and activated there.
- a setup process is run through in order to establish communication between the gateway 10 and the transmitter unit ok
- the display of the application on the mobile terminal device 30 now shows the current signal strength, i.e. the signal quality of the communication signal transmitted from the transmitter unit 20 to the gateway 10.
- the current signal strength i.e. the signal quality of the communication signal transmitted from the transmitter unit 20 to the gateway 10.
- a defined minimum signal strength which is stored in the memory of the gateway 10 as a threshold value, the user is signaled on the terminal 30 whether the current signal quality is sufficient for smooth communication between the transmitter unit 20 and the gateway 10.
- the transmitter unit 20 can be brought to a location further away from the pump 60 by means of an extension cable for the connection 23, at which a sufficient signal quality is displayed.
- the location or the characteristics of the gateway antenna could also be modified.
- the method is then repeated for the next pump or the next installation location, it being possible to use the same or a further transmitter unit 20 for this purpose.
- the transmitting unit 20 is then brought into the area of the second pump and an installation location there is determined in an identical manner. If all installation locations have been determined according to the method according to the invention, the gateway 10 can create an installation plan on the basis of the respectively stored installation locations and display it to the user.
- the respective transmission unit 20 is then connected to the assigned sensor unit 21 by cable 23 and confirmed by a feedback in the application on the terminal 30.
- the sensor 21 can then be installed. This can be done using the stored position data and other image data of the industrial plant, if necessary in connection with an augmented / virtual reality application, by comparing the images of the respective pump with a database and the installation location is displayed to the user via the augmented / virtual reality application
- an association can be created between the sensor 21 and the pump in the cloud 50.
- the transmitter unit 20, which is also mounted is then put into operation with the sensor head 21 connected, and the application gives a feedback when the transmitter unit 20 with sensor 21 has been successfully recognized. For the test, a first measurement is automatically triggered and the measured values determined are displayed in the application.
