Description

A SYSTEM CONFIGURED FOR UNIT REPLACEMENT AT A TARGET

Field

The present invention relates to a system configured for replacing or changing a unit at a target. More specifically, the present invention relates to the field of systems for replacing or changing a unit within a target, where the target may be a machine, wind turbine, or a crane, and where the unit to be replaced is a filter, pump, fastening means, or an oil unit. Background

Maintenance of a machine includes replacement of worn out and/or malfunctioning parts or units, such as replacement of filters, pumps, fastening means, and lubricant units. The maintenance is essential for an efficient, stable, and durable operation of the machine.

Replacement of filters and lubricant units are particularly important, since machines cannot work properly without lubricants or lubricators. If the machines, or parts thereof, do not get lubricant, the efficiency of the machine will decrease and/or the machine may dry out, and in worst case, get destroyed. Thus, machines must be frequently lubricated by using lubricants. Examples of lubricants include oils, such as mineral oils, synthetic oils, and vegetable oils. Other examples of lubricants include aqueous based lubricants and solid lubricants, e.g. polytetrafluoroethylene (PTFE) and graphite. It is further important that the machines, or parts thereof, get lubricant of the correct quality. Typically, the lubricant is replaced simultaneously with replacing a filter unit used for filtering the lubricant. The filter unit filters the lubricant to e.g. reduce the amount of contaminants, impurities, and degradation products, which may accumulate during use of the lubricant. The quality of lubricants and filter units will degrade during use, and it is therefore necessary to replace the lubricant and filter after a period of use. For example, a mineral oil may be subjected to thermal degradation, leakage, or evaporation during use, and a filter may clog during use, due to the assembly of impurities from the filtrated lubricant. For correct and efficient maintenance, it is essential that the lubricant and/or filter unit is replaced with an identical oil and/or filter unit. For example, a different type of oil viscosity or density, or a different filter sizing, may be detrimental for the operation as well as the long-term stability and durability of the machine. There is therefore a need for checking if the replacement unit is identical to the target unit to be replaced.

This check is conventionally done by a human or a sensor. A check performed by a human is subject to human errors. Furthermore, properties such as oil type or filter size may not be visible to the human eye. Especially for high-maintenance, expensive, and less accessible machines, such as wind turbines and cranes, there is a desire for reducing the risk of human errors.

The check may also be performed by a sensor. However, a sensor is typically not a flexible solution, since the operation conditions of the sensor are pre-defined, typically from a factory setting, for example to match a specific working condition. Thus, a sensor configured to check a filter in a wind turbine, is not configured for checking a filter in a crane, or for checking a lubricant in a machine.

A sensor may be adapted to be flexible between specific jobs, machines, filters, and lubricants. This will require re-definition of the pre-defined operation conditions in the sensors at factory level, and/or re-definition of the pre-defined operation conditions in the sensor at a user level. A data processing unit is usually coupled to the sensor(s). These sensors typically also have a memory, either coupled to the data processing unit or the sensor.

The memory might be accessible through software, however typically at factory level in order to avoid safety issues and non-proper working conditions. Thus, tampering with sensors, in particular with their pre-defined operation conditions is typically difficult and prohibited to avoid safety issues.

Thus, there is a need for systems facilitating machine maintenance operations, where the risk of human errors are reduced, and with improved flexibility and reliability.

Summary

As described above, there is a need for a system facilitating machine maintenance operations with improved flexibility and reliability. Particularly, there is a need for a system configured for unit replacement at a target, where the replacement unit is easily defined or re-defined in such a way that it does not compromise safety, and where the risk of human errors is reduced.

One aspect of the disclosure relates to a system configured for unit replacement at a target, comprising:

a target unit 21 configured for replacement;

a replacement unit 22,

wherein the target unit and/or the replacement unit are in communication with a release unit 2, wherein the release unit has a release setting and a block setting;

a controller 3 configured for controlling the release unit,

a data processing unit 5 configured for communicating with the controller and configured for receiving:

- one or more command parameter(s) 4 via a first communication device 23, wherein the first communication device is a wireless device, such as a tablet, a smart phone, a laptop, or a device configured with near field coupling or Bluetooth,

- a first set of condition parameters 6 via the first communication device, wherein the first set of condition parameters is related to at least the replacement unit;

- a second set of condition parameters 7 via a second communication device 8, wherein the second set of condition parameters are related to at least the target unit; and

wherein the data processing unit 5 is further configured for checking whether the first set of condition parameters 6 matches the second set of condition parameters 7, such that:

- if the match is valid, the data processing unit is configured for

transmitting said command parameter(s) to the controller, whereby the release unit 2 is set to release, or

- if the match is invalid, the data processing unit is configured for not transmitting said command parameter(s) to the controller, whereby the release unit 2 is set to block. According to the aspect, the target unit and/or the replacement unit are in

communication with a release unit, wherein the release unit has a release setting and a block setting.

In a preferred embodiment, the communication is a solid physical communication, such as a locking mechanism facilitating detachably attachment of the target

unit/replacement unit to the release unit 2. Thus, when the release unit is set to the block setting, the locking mechanism is locked, and the target unit/replacement unit are physically attached to the release unit. When the release unit is set to the release setting, the locking mechanism is unlocked, and the target unit/replacement unit are physically detached from the release unit.

In another preferred embodiment, the target unit/replacement unit are in electronic communication with the release unit. Thus, the communication is not a solid physical communication, but e.g. through a communication device, and the release setting and block setting may be provided as a notification. For example, the notification may be an audio, visual, vibrational, or electronic message notification. Thus, when the release unit is set to the block setting, a first audio notification may be provided, and when the release unit is set to the release setting, a second audio notification may be provided.

Alternatively, the release unit may comprise a digital blocking as opposed to a physical locking mechanism. The digital blocking should preferably be activated if the release unit is set to the block setting. In case the digital block is activated without the physical lock activated, the user/technician may still remove the target/replacement unit and perform the replacement. However, in this case, the system should preferably respond to the event such as by providing a warning to the user, stopping the workflow, flagging the event, and/or logging the event. In either case, the system should preferably characterize the maintenance as being incorrect and create a digital trace / log of the event. The warning to the user may be provided as a text message to the user, an audio notification, flashing lights, and/or combinations thereof. The warning may be provided via an electronic application, e.g. running on the first communication device.

It may also be that the user is unable to report the maintenance while the digital block is activated. Hence, this may make it impossible for the user to finish the reporting of the maintenance, which is typically done electronically. This serves the purpose of highlighting an event, wherein the user proceeded with the maintenance even though the release unit was in a block setting (e.g. due to a mismatch between the properties of the replacement unit and the target unit). The digital blocking should preferably be revoked once there is a match between the first set of parameters and the second set of parameters - in this case, the release unit is preferably set to release.

The release unit may also employ a combination of a physical lock mechanism and a digital lock, as described above.

A further aspect relates to a kit, comprising the system according the aspect above, the first communication device 23, and the second communication device 8.

A further aspect relates to a method for unit replacement at a target, comprising the steps of:

providing a target unit configured for replacement,

providing a replacement unit,

wherein the target unit and/or the replacement unit are in communication with a release unit, wherein the release unit has a release setting and a block setting,

providing a first communication device and a second communication device, obtaining a first set of condition parameters via the first communication device, wherein the first set of condition parameters is related to at least the replacement unit,

obtaining a second set of condition parameters via a second communication device, wherein the second set of condition parameters are related to at least the target unit,

checking if the first set of condition parameters matches the second set of condition parameters,

setting the release unit to release, if the match is valid, or setting the release unit to block if the match is invalid.

In a preferred embodiment of the method, the check is carried out by a data processing unit. In a further preferred embodiment, the release unit is controlled by a controller.

In a preferred embodiment, the method is configured for the system according to the first aspect. Description of drawings

Detailed description

The invention is as defined in the claims.

The invention is described below with the help of the accompanying figures. It would be appreciated by the people skilled in the art that the same feature or component of the device are referred with the same reference numeral in different figures. A list of the reference numbers can be found at the end of the detailed description section.

Unit replacement

Machines, such as wind turbines or cranes, comprises multiple components, parts, or units. Some of the components have a shorter lifetime than the machine, and are therefore replaced or changed during the operational lifetime of the machine. Examples of such replaceable units include filters, pumps, fastening means, gears, brakes, carburettors, valves, gaskets, containers, light bulbs, oil units, and other wearing parts.

The replacement may be carried out by removing the used unit, e.g. by dismantling a filter, or draining or discharging an oil unit, and inserting a new unit, e.g. mounting a new filter, or replenishing the oil unit. Thus, the units are inherently configured for replacement. The draining or discharging of an oil unit may occur during use due to leakage and evaporation. Thus, optionally, the replacement of an oil unit includes only the replenishment step, or refilling, of the oil unit.

The machine may also be referred to as a target. Accordingly, the term“target unit” refers to the used unit, which needs to be removed and replaced, and the term “replacement unit” refers to the new unit, which is inserted to replace the used target unit.

System

In the following, the unit replacement will be mainly exemplified as a filter replacement or change. The skilled person will know that the described systems may be used correspondingly for replacements of other target units, such as pumps, fastening means, gears, valves, containers, and oil units. Correspondingly, the system may be used for combined replacements, such as a filter replacement combined with an oil unit replacement.

Figure 1

Figure 1 shows an embodiment of a system according to the present disclosure configured for a target unit replacement, where the target is a machine. The illustrated system comprises a target unit 21 , exemplified as the filter unit, a replacement unit 22, exemplified as a filter unit of an identical type to the target unit, and a first

communication device 23. The first communication device may be a mobile phone with a tag reader in the form of a scanner as sketched in Figure 1 , and comprising a data processing unit 5 (shown in Figure 2).

The tag reader may be based on any reading means, including a manual reading, and/or readings configured for near field coupling or Bluetooth. For example, the reading may be based on a tag reader, a scanner, optical image scanner, API

(application programming interface), radio, and/or QR code.

In Figure 1 , the target filter unit 21 is placed within a machine/machine part 24, such as a machine part comprising oil. Depending on the degree of use or clogging of the filter, the target filter will need to be replaced at a point in time, optionally in combination with an oil replacement. The replacement filter unit 22 may be located outside or remotely from the machine, such as placed in a mobile storage unit 25. Optionally, the storage unit comprises several replacement filter units and/or oil units, where the filter units and/or oil units may be of the same type or of different types.

To facilitate the replacement process, and further to control the position of the target unit within the machine, and/or the position of the replacement units within the storage unit, it is advantageously that the target unit and/or the replacement units are in communication with a release unit 2. Advantageously, the communication is a solid physical communication, such as a locking mechanism facilitating detachably attachment of the units to a release unit 2 as exemplified in Figure 2. The release unit has two settings: a release setting allowing release and removal of the

target/replacement unit, and a block setting preventing release and removal of the target/replacement unit in case of a physical locking mechanism. Alternatively, the release and removal of the target/replacement unit may be allowed in case of a digital block, however preferably with some implications to the electronic report/log of the maintenance. The release units may be controlled by a controller 3 (exemplified in Figure 3).

Alternatively, the target unit/replacement unit are in electronic communication with the release unit. Thus, the communication is not a solid physical communication, but e.g. through a communication device, and the release setting and block setting may be provided as a notification. For example, the notification may be an audio, visual, vibrational, or electronic message notification. Thus, when the release unit is set to the block setting, a first audio notification may be provided, and when the release unit is set to the release setting, a second audio notification may be provided.

To further facilitate and simplify the replacement process, it is advantageous that only the target unit or the replacement unit is detachably attached to a release unit. Due to the higher flexibility of the positioning of replacement units within the storage unit, compared to the positioning of the target unit within the target, it is advantageous that the replacement units are detachably attached within the storage unit. The replacement units may be detachably attached to a common release unit, optionally configured to release one or more replacement units at a time, or each replacement unit may be detachably attached to an individual release unit. In a preferred embodiment of the disclosure, the replacement unit(s) are detachably attached to one or more release unit(s).

Figure 2

Figure 2 shows a further embodiment of the system according to the present disclosure. The system comprises a target filter unit 21 , a replacement filter unit 22, and a first communication device 23. The first communication device may be a mobile phone with a tag reader 1 in the form of a scanner as illustrated in Figure 1 , and optionally a data processing unit 5. Alternatively, the data processing unit is placed external to, and in communication with the first communication device, as illustrated in Figure 2.

The target unit is a filter placed within a machine/machine part 24, such as a machine part comprising oil. Depending on the degree of use/clogging of the filter, the target filter will need to be replaced at a point in time, optionally in combination with an oil replacement.

The replacement filter unit is located outside the machine, such as placed in a mobile storage unit 25. Optionally, the storage unit comprises several replacement filter units and/or oil units, where the filter units and/or oil units may be of the same type or of different types.

As described for Figure 1 , the target unit and/or the replacement units may be detachably attached to a release unit 2, and advantageously the replacement units are detachably attached to one or more release units, as illustrated in Figure 2. The detachably attachment may be in the form of a solid physical communication, or in the form of an electronic communication. Thus, each replacement unit is connected or detachably attached to one or more release unit(s), where the release unit(s) 2 has a release setting allowing release and removal of one or more unit(s) from the storage, and a block setting preventing release and removal of one or more unit(s) from the storage in case of a physical locking mechanism. In case of a digital blocking setting, the replacement/maintenance may still be completed, however the system should preferably log the event as being a faulty maintenance (e.g. due to a mismatch between the target unit and the replacement unit), and/or warn the user of the mismatch, and/or prevent the user from completing an electronic report of the performed maintenance. The release units may be controlled by a controller 3.

First and second set of condition parameters and command parameters)

A filter change includes replacement of the target filter unit 21 with the replacement filter unit 22. The change is allowed and/or initiated by one or more command parameter(s) 4 via the first communication device, provided a set of condition parameters are met.

The first set of condition parameters 6 are related to the replacement unit, and the second set of condition parameters 7 are related to the target unit, as illustrated in Figure 2. As also illustrated in Figure 2, the condition parameters may be obtained by reading/scanning the target filter unit and the replacement unit, e.g. by use of a tag reader 1 of the first communication device 23. The order of reading/scanning may be any order.

The reading of the replacement filter unit may be related to the type and/or size of the filter, and thus constitute a first set of condition parameters 6 related to the replacement unit. The reading of the target filter unit may be related to the type of filter and/or size of the filter, and thus constitute a second set of condition parameters 7 related to the target.

Alternatively, the target unit and replacement unit represent oil units, where an oil unit may be characterised by the oil type, density, and/or viscosity. Thus, the readings of the target oil unit and replacement oil unit are related to the type, density, and/or viscosity, thus constituting the first and second set of condition parameters.

The oil unit as disclosed herein may further in some embodiments comprise a tracer material. In this manner, the present disclosure may in some embodiments relate to a system for replacing an oil unit at a target, wherein the oil unit comprises the tracer material. Using a tracer material in the system may provide that the second set of condition parameters is able to be detected via a detector. That detector may be linked to the second communication device or the first communication device. The second condition parameters, related to the target unit, for example the type of oil, may then be transmitted via the second communication device to the data processing unit. In one embodiment of the disclosure, the first set of condition parameters 6 and/or the second set of condition parameters 7 is/are one or more of the following: type of lubricant in a container, density of lubricant in a container, viscosity of lubricant in a container, amount of lubricant in a container (e.g. filling level), time(s) of use of the container, type of unit, density of unit, and viscosity of unit, such as type of filter, or density/viscosity of an oil unit.

The data processing unit is configured for checking whether the first set of condition parameters matches the second set of condition parameters, e.g. if the type and/or size of target filter is the same as the replacement filter. If the match is valid, i.e. the types and/or sizes matches, the data processing unit is configured for allowing transmittance of a command parameter to the controller, whereby the release unit of the replacement unit is set to release. Thus, the replacement filter may be removed from the storage unit, and replaced with the target unit filter. Furthermore, the electronic report of the maintenance may preferably be completed, e.g. via an application.

If the match is invalid, i.e. the type or size of the target filter is not the same as the replacement filter, the data processing unit is configured for denying transmittance of a command parameter to the controller, whereby the release unit of the replacement unit is set to block. Thus, the replacement filter preferably cannot be removed from the storage unit, and replacement of the target unit is avoided. Alternatively, the blocking setting is a digital block, which may imply that the maintenance can be completed under certain implications (e.g. logging the maintenance as faulty).

When the first set of condition parameters is received at the data processing unit, there might be a temporary memory, such as a cache, that stores the first set of condition parameters, and/or the second set of condition parameters, for example until the match according to the invention has been performed in relation to other set of condition parameters.

The command parameter 4 may be in the form of an activation of the release unit setting, i.e. activation of the release setting, or the block setting. Alternatively, or in addition, the command parameter may be in the form of a visual indicator, indicating a release setting or a block setting. In a preferred embodiment, the command parameter(s) 4 are selected from the group of: indicate and/or activate the release setting of the release unit, and indicate and/or activate the block setting of the release unit.

The controller, or rather the data processing unit, may accordingly be programmed to respond to these commands.

Thus, the present disclosure does not rely on build-in parameters in sensors or manual checks, which is in contrast to previously described systems.

First and second communication device

Preferably, both the target unit and the replacement units are read via the same first communication device 23. This is advantageous to reduce the number of parts of the kit, and for simplicity. The reading may be based on any reading means, including a manual reading, and/or readings configured for near field coupling or Bluetooth. For example, the reading may be based on a tag reader, a scanner, optical image scanner, API (application programming interface), radio, and/or QR code. For example, both the target unit and the replacement unit may be read using the tag reader 1 of the first communication device, as sketched in Figure 2.

However, it may also be advantageous that the first or the second set of condition parameters are read via a second communication device 8, such as a tag reader or a scanner located within or on the target unit, or respectively a tag reader or a scanner located within or on the storage unit, as illustrated in Figure 2. This may facilitate a faster replacement processes. Optionally, the second communication device is a manual input device configured for manually defining the second set of condition parameters. For example, the type of target filter and/or replacement filter may be read visually by a user, and registered manually. Further optionally, the tag reader or scanner may be placed remotely from the system, to improve the flexibility of the system.

As for the first communication device, the reading of the second communication device may be based on any reading means, including a manual reading, and/or readings configured for near field coupling or Bluetooth. For example, the reading may be based on a tag reader, a scanner, optical image scanner, API (application programming interface), radio, and/or QR code.

In an embodiment of the disclosure, the system comprises a second communication device 8. In a further embodiment, the second communication device is a tag reader located within or on the system, wherein the tag reader is configured for reading a tag associated with the target unit 21 or replacement unit 22. In another embodiment, the second communication device is a tag reader located remotely from the system, wherein the tag reader is configured for reading a tag associated with the target unit 21 or replacement unit 22.

In a further embodiment, the second communication device is a scanning device configured for reading a label associated with the target unit. The label may be located within or on the system or target unit. The label may however also be placed remotely from the system or target unit, such as on an adjacent part of the machine. In a yet alternative embodiment, the second communication device is a manual input device configured for manually defining the second set of condition parameters.

In a preferred embodiment, the second communication device 8 is different from the first communication device 23. However, in some embodiments, the first

communication device and the second communication device is a single device.

In some embodiments, the first and/or second communication device is a wireless device such as a tablet, a smart phone, a laptop, or a device configured with near field coupling or Bluetooth.

Preferably, the first and/or second communication device is configured for being mounted to a user of the kit. This may allow for easy control of the kit or at least for easy input to the controller. Thus, in some embodiments, the first and/or second communication device is configured to be mounted on the wrist of the user of the kit. In this case, the first and/or second communication device may be a smart watch, or more generally, a remote control. In other embodiments, the first and/or second

communication device is configured to be mounted on the arm of the user. In this case, the first and/or second communication device may be a smart phone or more generally, a remote control. Data processing unit

In one embodiment, the data processing unit is further configured for: (a) receiving at least one request from the first communication device, wherein the request is for the data processing unit to identify at least some part of the system and (b) transmitting an answer back to the first communication device, where the answer indicates that the data processing unit has identified at least some part of the system.

The request from the first communication device may be automatic, for example once contact has been established such as with Bluetooth or near field coupling, or the request may be initiated by a user, for example by sending a message to the system.

The answer may be a message such as“yes”, a number, or an ID code. The number or ID code may also be sent to a central database station via the first communication device. In this way, the user is able to go to the central data base station and for example see which part of the system, e.g. replacement unit, that is being used or has been used. The number or ID code may for example identify replacement unit. The answer may also be along the lines of“Are you sure you want to release replacement unit number 42?” After receiving an answer in the form of a question, the user may return with an acceptable or a non-acceptance value via the first communication device.

The embodiment as described provides for additional safety.

In one embodiment, the data processing unit is located in the kit, e.g. incorporated with the controller and/or release unit.

However, in other embodiments, the data processing unit is located remote from the kit. For example, the data processing unit may be located in the first communication device or in a central database station.

In a preferred embodiment, the data processing unit is further configured for providing a status report based on the operation of the controller. In other words, the data processing is configured for determining the output of the controller, wherein the output of the controller is defined as input to the controller. In a most preferred embodiment, the data processing unit is further configured for transmitting the status report to the first communication device. For example, the status report may be an indication of whether the replacement unit is replaced or not. The status report may also be how many replacement units are replaced, what type of replacement units, the remaining amount of replacement units, and/or what time the replacements were carried out.

Third and fourth set of condition parameters

The filter change or oil change may be initiated based on a user decision. For example, when a filter or oil unit has been used for a predefined amount of time, a change is recommended, and a user decides whether to initiate a change.

Alternatively, the filter/oil change may be initiated by the status of the filter/oil, i.e.

information related to the actual filter clogging degree or oil purity. For example, filter/oil change may only be required if respectively the filter is clogged to a predefined degree, or the purity of the oil has degraded to a predefined contamination degree. This will enhance the efficiency and the costs of the replacement process.

The actual status (i.e. clogging degree or contamination degree) on the filter or oil may be measured by sensors. The reading of the sensors are thus related to the status, and constitute a third set of condition parameters 9 related to the target, as illustrated in Figure 2. Preferably, the reading of the sensors may be obtained via the first communication device.

The predefined values, or threshold values, will depend on the type of filter, the type of machine (part), as well as the type and method of use, and may be obtained from a database. Thus, the predefined values constitute a fourth set of condition parameters 10 related to the target, as illustrated in Figure 2. The threshold values are read or obtained via the first communication device, e.g. via an app, or a third communication device 11 , such as a web page, as illustrated in Figure 2. Optionally, the fourth set of condition parameters are transmitted via the first communication device, as illustrated in Figure 2.

Thus, the need for a filter/oil change may be based on the data processing unit being configured for checking whether the third set of condition parameters matches the fourth set of condition parameters. By the term“matching” is meant that the third set of condition parameters fulfills the requirements for replacement, i.e. if the sensed value is the same or exceeds the threshold value. If the match is valid, the data processing unit is configured for allowing transmittance of a command parameter(s) to the controller, whereby the release unit is set to release. If the match is invalid, i.e. the clogging/purity status required for a replacement is not fulfilled, the data processing unit is configured for denying transmittance of a command parameter(s) to the controller, such that the release unit is set to block. This is also sketched in Figure 2.

In an embodiment of the disclosure, the data processing unit 5 is further configured for receiving:

- a third set of condition parameters 9 via the first communication device 23, wherein the third set of condition parameters is related to the target, and

- a fourth set of condition parameters 10 via a third communication device 11 ,

wherein the fourth set of condition parameters is related to the target.

In an embodiment of the disclosure, the data processing unit 5 is further configured for checking whether the third set of condition parameters 9 matches the fourth set of condition parameters 10, such that:

- if the match is valid, the data processing unit is configured for allowing

transmittance of said command parameter(s) to the controller, whereby the release unit 2 is set to release, or

- if the match is invalid, the data processing unit is configured for denying

transmittance of said command parameter(s) to the controller, whereby the release unit 2 is set to block.

For easier detection of filters/oils that fulfills the requirements for replacement, i.e. filters/oils where the sensor measures status values equal to or above the threshold values, the status of a filter/oil may be shown by an indicator, such as a visual indicator. Advantageously, the indicator shows the relative status, i.e. the status relative to the threshold value, and optionally the expected residual time before the threshold is reached.

For further easy, fast, and precise detection of needed replacement, the data processing unit is configured for providing a notification when a threshold value is matched or exceeded. The notification may be an audio, visual, vibrational, or electronic message notification, such as an email, sms, notification in app, or call.

The sensors may be placed within a machine part, and therefore difficult to access and monitor using a communication device. Advantageously, the sensors are configured for transmitting the measured status to a communication device, such as the first communication device or a third communication device. For example, the

measurement of the sensor may be transmitted to a third communication device that is a tag reader located at an accessible part of the target, such as in or on the target, as illustrated in Figure 2.

Third communication device

As described above, the third and fourth condition parameters are advantageously a filter clogging degree and/or an oil purity or contamination degree. A third

communication devices as described above provides for a system where human errors are further limited. The third communication device facilitates easier and simpler readings of the third and/or fourth set of condition parameters. For easy and accessible readings, the condition parameters are obtained by a tag reader, a scanner, or a manual input.

In an embodiment of the disclosure, the third communication device 11 comprises a tag reader located within or on the system, wherein the tag reader is configured for reading a tag associated with the target unit. In a further embodiment, the third communication device comprises a tag reader located at an accessible part of the target, wherein the tag reader is configured for reading a tag associated with the target unit.

In an alternative embodiment, the third communication device 11 is a scanning device configured for reading a label associated with the target. In another alternative embodiment, the third communication device is a manual input device configured for manually defining the fourth set of condition parameters.

To facilitate the replacement process, the third communication device is

advantageously similar to the second communication device. Advantageously, the third communication device is a wireless device such as a tablet, a smart phone, a laptop, or a device configured with near field coupling or Bluetooth. In an embodiment of the disclosure, the second communication device 8 and/or the third communication device 11 is a wireless device such as a tablet, a smart phone, a laptop, or a device configured with near field coupling or Bluetooth.

As for the first and second communication device, the reading of the third

communication device may be based on any reading means, including a manual reading, and/or readings configured for near field coupling or Bluetooth. For example, the reading may be based on a tag reader, a scanner, optical image scanner, API (application programming interface), radio, and/or QR code.

Target position

As described above, the third and fourth condition parameters are advantageously a filter clogging degree and/or an oil purity or contamination degree.

However, the need for changing a target unit may also be indicated by the position of the target, the position of an indicator placed on the target, or transmitted by the indicator. This means that the initiation of the replacement may be further controlled by the position of the target. Similarly, the need for changing a target unit may be indicated by the type of machine, or type of a machine part. For example, based on measurements or operational procedures, it may be decided that target units at certain locations or of a certain types, must be replaced. Thus the third and/or fourth set of conditions parameters may be related to the location of a machine, and/or type of machine.

For example, a filter/oil change and the associated release of the replacement unit, is only possible if the position of the kit, i.e. the target unit, and/or replacement unit, and/or first communication device, matches the position of the target or indicator, or the information transmitted by the indicator.

Advantageously, the location or positioning constitutes the third and fourth condition parameters, or a fifth condition parameter. A location may be provided by a positioning device, such as a global positioning system (GPS), and the GPS may be located in the kit. Advantageously, the positioning device is located in the first communication device, whereby the first communication device may be used for locating all parts of the kit, e.g. by using a scanner. The data processing unit is advantageously used for determining a valid match between the location of the parts, and the data processing unit is further advantageously located in the first communication device, thereby providing a simple and compact kit.

In one embodiment, the third set of condition parameters 9 and/or the fourth set of condition parameters 10 is one or more of the following: type of a machine, type of a machine part, location of a machine, filter clogging degree, and oil purity or oil contamination degree.

In an embodiment of the disclosure, the fourth set of condition parameters 10 is provided by a positioning device, such as a global positioning system, wherein the positioning device is located in the kit and/or the first communication device 23.

In an embodiment of the disclosure, the data processing unit is located in the first communication device.

As described above, in a preferred embodiment, the data processing unit is further configured for receiving: a third set of condition parameters via the first communication device, wherein the third set of condition parameters is related to the target, and a fourth set of condition parameters via a third communication device, wherein the fourth set of condition parameters is related to the target. This avoids further human errors.

In a most preferred embodiment, the data processing unit is further configured for checking whether the third set of condition parameters matches the fourth set of condition parameters, such that: if the match is valid, the data processing unit is configured for transmitting said command parameter(s) to the controller, whereby the release unit is set to release, or if the match is invalid, the data processing unit is configured for not transmitting said command parameter(s) to the controller, whereby release unit is set to block. Again, this avoids further human errors.

For example, the embodiment provides for the system to only release the replacement unit, once the replacement unit is very close to the target. If two or more targets are placed close to each other, and the two targets for example require different replacement units, the user holding the kit, does not need to worry about which target requires the one type of unit or another type of unit. The user may just place the kit including the replacement unit close to the target. The kit releases the replacement unit if the type of replacement unit is correct.

In most embodiments, the data processing unit is configured for receiving said command parameters and said conditions via a receiver configured for communicating wirelessly with the first communication device. For example, if the first communication device is a mobile phone, the receiver may be a near field coupling receiver, a

Bluetooth receiver, and/or an antenna configured for receiving signals via wireless internet or signal with frequencies as transmitted by mobile phones.

In an embodiment of the disclosure, the data processing unit 5 is configured for receiving said command(s) 4 and the first set of condition parameters 6 via a receiver configured for communicating wirelessly with the first communication device 23.

In another embodiment, the fourth set of condition parameters is provided by a positioning device, such as a global positioning system, wherein the positioning device is located in the kit and/or the first communication device. Having a global positioning system, may allow that the coordinate set of the kit and/or the first communication device is changed when for example the kit is mobile and the user transports the kit and/or the first communication device.

Advantageously, the location or positioning constitutes a fifth condition parameter. A location may be provided by a positioning device, such as a global positioning system (GPS), and the GPS may be located in the kit. Advantageously, the positioning device is located in the first communication device, whereby the first communication device may be used for locating all parts of the kit, e.g. by using a scanner. The data processing unit is advantageously used for determining a valid match between the location of the parts, and the data processing unit is further advantageously located in the first communication device, thereby providing a simple and compact kit.

Display

Figure 3 shows an embodiment of a system kit configured for unit replacement at a target, where the kit comprises a first communication device with a display, where the display is configured for showing an identified part of the kit. The display shows respectively, (a) the replacement unit, (b) the target unit and/or the machine, (c) the actual location and/or an indicated location, and (d) initiation of the replacement process.

A part of the kit may be identified by registering, e.g. scanning, the part using the first communication device. This may be obtained by a data processing unit configured for receiving at least one request from the first communication device, wherein the request is for the data processing unit to identify at least some part of the kit, and transmitting an answer back to the first communication device, where the answer indicates that the data processing unit has identified at least some part of the kit.

Thus, a simple an efficient change of the target unit may be obtained. For example, the first communication device may be used for first registering the replacement unit (Figure 3a), then locate the target unit(s) to be replaced, optionally shown on a map, as illustrated in Figure 3b, then when the location of a target unit is reached, the target unit is registered (Figure 3c). If there is a match between the condition parameters, the replacement process is initiated, and allowed (Figure 3d).

In an embodiment of the disclosure, the data processing unit is further configured for:

- receiving at least one request from the first communication device, wherein the request is for the data processing unit to identify at least some part of the kit, and

- transmitting an answer back to the first communication device, where the answer indicates that the data processing unit has identified at least some part of the kit.

Tracking

For efficient and safe operation of the kit, it is advantageous to keep track of the replacements performed and the status of the storage unit. Thus, the data processing unit is advantageously configured for providing a status report on how the release unit is controlled, and for transmitting the status report to the first communication device. The first communication device is further advantageously configured for logging the status reports. Thus, the replacements performed can be tracked. This may be required for complying with safety and operational conditions.

In an embodiment of the disclosure, the data processing unit is further configured for providing a status report based on how the release unit is controlled. In an embodiment of the disclosure, the data processing unit is further configured for transmitting the status report to the first communication device.

In an embodiment of the disclosure, the first communication device is configured for logging the status report.

To further reduce the risk of unintended and accidental replacements, the kit may comprise a central communication station configured for transmitting the command parameters, and the condition parameters to the first communication device. Thus, accidental replacements on-site may be avoided from a central position.

In an embodiment of the disclosure, the kit further comprises a central communication station 12, configured for transmitting said command parameter(s) and the first set of condition parameter(s) to the first communication device.

According to the disclosure, the first communication device is used to send command parameters to the controller of the kit.

Also in accordance with the disclosure, a user is able to send both the control parameters and the first set of condition parameters to the data processing unit.

Reconfiguration

The present disclosure facilitates that the first communication device can send the first set of condition parameters to for example a plurality controllers. In other words, the present disclosure provides for easy configuration of a kit for variable purposes, e.g. for changing different types of filters and/or oils.

It is an advantage of the present disclosure that the first communication device sends the control parameters or command parameter(s).

It is another advantage of the present disclosure that the fist communication device sends the first set of condition parameters.

It is a third advantage of the present disclosure that the system and kit is easy to reconfigure in terms its condition parameters. In particular, and according to the disclosure, the feature related to the first set of condition parameters, received at the data processing unit via the first communication device, is advantageous because it facilitates that a condition of one or more parts of the kit (at least the target and/or replacement units) is easily defined or re-defined, namely via the first communication device.

In preferred embodiments, the first and/or second set of condition parameters is one or more of the following: type of lubricant in a container, density of lubricant in a container, viscosity of lubricant in a container, amount of lubricant in a container, time(s) of use of the container, type of unit, certification of unit, density of unit, and viscosity of unit, such as type of filter, filter certification, or density/viscosity of an oil unit.

By“certification of unit” is meant information identifying the unit, such as a product certificate, or producer information, such as a product label. For example a filter may be accredited certified according to an ISO standard, and the certificate is the information identifying the unit. Alternatively, a producer may include a product label directly on the product or associated with the product, e.g. in the form of a readable mark or code, and the label is thus the information identifying the unit or the

certification of the unit.

According to the present disclosure, it is possible to easily define the command parameters, control parameters, and e.g. the first set of conditions parameters, because the first communication device is wireless. Changing the first set of condition parameters can for example be done via the tablet or the smart phone.

As known, wireless devices can be equipped with passwords, and thus the invention does not compromise safety.

The present invention also provides a low cost kit where a permanent memory does not need to be a part of the kit. As a matter of fact, any of the communication devices according to the present invention do not need to have a permanent memory to provide a working kit.

The third condition parameters may be measurable such as with sensor(s). The third condition parameters may in some embodiments be readable, and thus communicated to the data processing unit. Hence, in some embodiments, sensor(s) to measure operational properties may not be needed.

As to be understood from the disclosure, the present disclosure relates to a semi automatic or automatic kit for changing filters and/or oils.

Typical target units as described can advantageously be modified such that instead of communicating with an internal and permanent memory and an internal data processing unit, existing sensor(s) can be re-configured to communicate with the data processing unit according to the invention. In this way, the output of existing sensor(s) in existing target units may be re-directed to the data processing unit according to the invention, whereto the first set of condition parameters is communicated.

System and kit

Advantageously, the system according to the present disclosure may be part of a kit. Thus, the kit comprises the target unit, the replacement unit, the release unit, the controller, the data processing unit, the first communication device, and the second communication device.

Further preferably the system and kit are mobile. This means that the (used) target unit and the replacement units may be easily transported to and/or from the target. This provides for a solution, where a single kit can be used to replace a plurality of target units, instead of using a plurality of stationary kits, for example one per target.

However, in some embodiments, at least parts of the kit may be stationary. This has the advantage that when using a kit with stationary parts, the user does not need to carry the kit to the location, and the kit may be configured to be semi

automatic/automatic, such that the user does not need to be nearby the kit(s). Instead the user may be remotely placed from the kit(s).

In an embodiment of the disclosure, the kit comprises the system according to the present disclosure, the first communication device 23, and the second communication device 8. In a further embodiment, the kit further comprises a third communication device 11. The second communication device and the third communication device that may be part of the kit have been previously described in details.

In an embodiment of the disclosure, the system or kit is configured to be mobile. In another embodiment, the system or kit is configured to be stationary.

In an embodiment of the disclosure, the system further comprises the target, wherein the target is a machine or a part of the machine 24.

To facilitate the replacement process, and reduce the risk and impact of human errors, the first communication device is advantageously configured for logging the status as disclosed in relation to the aspect of the disclosure. Alternatively, or in addition, the kit further comprises a central communication station configured for receiving the status report from the first communication device.

In an embodiment of the disclosure, the first communication device 23 is configured for logging the status report of the data processing unit on how the release unit is controlled. In a further embodiment, the kit further comprises a central database station 12, configured for receiving the status report as just described. The status report is preferably transmitted from the first communication device.

Advantageously, part of the replacement process is carried out remotely from the kit, e.g. from the central communication station. In some embodiments, the kit further comprises a central communication station 12, configured for transmitting said command parameter(s) 4 and the first set of condition parameter(s) 6 to the first communication device 23.

In special embodiments, the first communication device is located in or on the target, for example in or on a machine. In this way, the one or more command parameter(s) are transmitted to the kit from the target. This allows for a fully automatic setup.

In an embodiment of the disclosure, the first communication device 23 is located in or on the target unit 21.

Example 1 - System kit configured for filter change at a target Figure 1 shows an embodiment of a kit configured for replacement of a filter at a target. The kit comprises the target filter unit 21 , placed within a machine/machine part 24 comprising oil, a replacement filter unit 22, placed in a mobile storage unit 25, and a first communication device 23, in the form of a mobile phone with a scanner.

Figure 2 shows a further embodiment of the kit, where the mobile storage unit further comprises a release unit 2 having a release setting allowing release and removal of the unit from the storage, and a block setting preventing release and removal of the unit from the storage. The mobile storage unit further comprises a controller for controlling the release unit, and a data processing unit 5.

The filter change may be requested manually, or based on a remote communication station, in the form of one or more command parameter(s) 4 via the first communication device.

Subsequently the target filter unit, and the replacement filter unit are read/scanned by the first communication device, and the reading from the replacement unit constitute a first set of condition parameters 6 related to the replacement unit, and the reading from the target unit constitute a second set of condition parameters 7 related to the target.

Preferably, both the target unit and the replacement units are read via the same first communication device. This is advantageous to reduce the number of parts of the kit, and for simplicity.

Alternatively, the first set of condition parameters are read via a second communication device 8, such as a tag reader located in or on the storage unit, to facilitate a faster replacement processes. Alternatively or in addition, the second communication device comprises a manual input from the user. Similarly, the second set of condition parameters may be read by a second communication device, and/or include a manual input from the user, to facilitate a faster replacement process.

The first set of condition parameters and/or the second set of condition parameters is/are one or more of the following: type of unit, density of unit, viscosity of unit, such as type of filter, or density/viscosity of an oil unit. For a replacement process, the first and the second set of condition parameters should relate to the same condition. Thus, the data processing unit may be configured for checking whether the first set of condition parameters matches the second set of condition parameters, i.e. if the type and/or size of target filter is the same as the replacement filter. If the match is valid, i.e. the types and/or sizes matches, the data processing unit is configured for allowing transmittance of a command parameter to the controller, whereby the release unit of the replacement unit is set to release. Thus, the replacement filter may be removed from the storage unit, and replaced with the target unit filter.

If the match is invalid, i.e. the type or size of the target filter is not the same as the replacement filter, the data processing unit is configured for denying transmittance of a command parameter to the controller, whereby the release unit of the replacement unit is set to block. Thus, the replacement filter cannot be removed from the storage unit, and replacement of the target unit is avoided.

The one or more command parameter(s) may also be generated automatically or semi- automatically.

For example, the filter change may be initiated by the status of the filter, i.e. information related to the actual filter clogging degree. The clogging status of the filter may be measured by sensors, and the status reading constitute a third set of condition parameters 9 related to the target, transmitted to the data processing unit via the first communication device.

The filter change command is only generated if the clogging status exceeds a predefined threshold, e.g. obtained from a database. Thus, the predefined values constitute a fourth set of condition parameters 10 related to the target, transmitted to the data processing unit via the first communication device.

The data processing unit is configured for checking whether the third set of condition parameters matches the fourth set of condition parameters, and a filter change command is generated if a match is detected. By the term“matching” is meant that the third set of condition parameters fulfills the requirements for replacement, i.e. if the sensed value is the same or exceeds the threshold value. If the match is valid, the data processing unit is configured for allowing transmittance of a command parameter(s) to the controller, whereby the release unit is set to release. If the match is invalid, i.e. the clogging/purity status required for a replacement is not fulfilled, the data processing unit is configured for denying transmittance of a command parameter(s) to the controller, such that the release unit is set to block.

For safer, and semi-automatic generation of the command parameters, the data processing unit is further configured for providing a notification when the threshold value is matched or exceeded. The notification may be an audio, visual, vibrational, or electronic message notification, such as an email, sms, notification in app, or call. A further manual input may be required to generate the command parameters.

measurement of the sensor may be transmitted to a third communication device that is a tag reader located at an accessible part of the target, such as in or on the target 1.

As described above, the third and fourth condition parameters may be related to a filter clogging status/degree. However, the need for changing a target unit may also be indicated by an indicator, or transmitted by the indicator. Thus, the indicator may be identified by the type of machine, type of machine part, or the location of the machine. For example, a filter change and the associated release of the replacement unit, is only possible if the position of the kit, i.e. the target unit, and/or replacement unit, and/or first communication device, matches the position of the indicator, or the information transmitted by the indicator.

Thus, the location or positioning information may be a part of the third and fourth condition parameters, or a fifth and/or sixth condition parameter. The location may be provided by a positioning device, such as a global positioning system (GPS), and the GPS may be located in the kit or kit parts. Advantageously, the positioning device is located in the first communication device, whereby the first communication device may be used for locating all parts of the kit, e.g. by using a scanner. The data processing unit is advantageously used for determining a valid match between the location of the parts. The first communication device may comprise a display, where the display is further configured for showing an identified part of the kit and/or the location of the identified part.

Figure 3 shows an embodiment of a first communication device with a display, where the display is configured for showing an identified part of the kit. In (a) the first communication device may be used for first registering the replacement unit, and the display shows the replacement unit. In (b) the target unit(s) to be replaced is registered by the first communication device, and the display shows the target unit and/or the machine. Optionally, the location of the target unit, and the location of the replacement unit is shown on a map on the display, as illustrated in (c). If there is a match between the condition parameters (target unit, replacement unit, and location), the replacement process is initiated and allowed as shown in the display (d).

The replacements performed and the status of the storage unit may be tracked. Thus, the data processing unit is advantageously configured for providing a status report on how the release unit is controlled, and for transmitting the status report to the first communication device, optionally to be shown on the display. The first communication device is further advantageously configured for logging the status reports.

The kit may further comprise a central communication station 12 configured for transmitting the command parameters, and the condition parameters to the first communication device. Thus, accidental replacements on-site may be avoided from a central position.
