AUTOMATIC LOCATION DETECTION OF A LOGGER

Description

[0001] The invention relates to a sensor kit comprising a sensor unit and at least one sensor unit mount. Such a sensor kit has a wide range of practical applications.

[0002] The invention further relates to a method for recording measured values, wherein a sensor unit is attached to a sensor unit holder and measured values ​​are automatically recorded on a recurring basis. Such a method is known in practice.

[0003] A loose, wearable receiver system is known from US 2016 / 324442 A1. Loose, wearable receiver systems are capable of detecting, recording, and / or transmitting physiological information, such as heart rate, temperature, or similar, via a wearer of the system.

[0004] WO 2023 / 084201 A1 discloses a holder arranged to receive and hold an electronic module, a method, and a system. The holder may comprise a power transmission interface arranged to transmit power to the electronic module when held by the holder.

[0005] From DE 10 2020 110429 A1 a contactless sensor identification system, a fitting for a sensor identification system and an electrochemical sensor for a sensor identification system are known.

[0006] The invention is based on the object of improving the operating characteristics of sensor kits and making the measurements performed more precise. This object is achieved by the features of the independent claims. Advantageous embodiments are described in the subclaims.

[0007] It should be noted that the features listed individually in the dependent patent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention. Furthermore, the features listed in the patent claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0008] To achieve the stated object, the invention proposes the features of claim 1. In particular, in a sensor kit of the type described above, the invention proposes that a magnetically active region be formed on the sensor unit holder, and that the sensor unit has a magnetic field sensor with which a relative position of the magnetically active region to the sensor unit can be determined. Preferably, the relative position is a measuring location. Particularly preferably, the relative position is a position in a measuring environment. Thus, the relative position can be determined precisely, reliably, and automatically, and does not require manual input from a user.

[0009] Advantageous embodiments of the invention are described below, which can optionally be combined with the features of claim 1 alone or in combination with the features of other embodiments.

[0010] To ensure the assignment of measured values ​​and the associated verification of limit values, the measuring location, for example, a refrigerator, a cool box, or a dishwasher, must be known. Currently, in stationary applications, this is done manually by a user during commissioning. The measuring location is therefore entered manually. However, this is very time-consuming and error-prone, leading to inaccuracies in the measuring location detection.

[0011] The present invention addresses this problem and aims to provide an improvement. The invention is particularly applicable to dynamic applications requiring temporary monitoring, such as transport, dishwasher use, or the "cook and chill" process, where the measurement location changes frequently and manual adjustment of the measurement location is no longer efficient and reliable.

[0012] The invention ensures that an automatic and thus reliable assignment of measured values ​​to the measuring location can take place under changing conditions.

[0013] In an advantageous embodiment, the sensor unit holder can be configured to accommodate the sensor unit in a defined position and / or orientation. Thus, the sensor unit can be brought close to the sensor unit holder, and information, such as location information, can be exchanged between the two objects.

[0014] The sensor unit can be designed as a logger.

[0015] In an advantageous embodiment, the magnetic field sensor can be designed as a Hall sensor. This provides a cost-effective and reliable measuring element. The Hall sensor can read location information or a position specification stored in the magnetically active area or specified by the position of a permanent magnet.

[0016] The Hall sensor can be discrete or integrated.

[0017] In an advantageous embodiment, the magnetically active region can be designed as a permanent magnet. This allows the magnetically active region to be designed simply and cost-effectively.

[0018] Preferably, the permanent magnet is glued to the sensor unit holder, magnetically attached to the housing or detachably attached.

[0019] The permanent magnet can be mounted at different positions on the sensor unit mount. The different positions of the permanent magnet allow the sensor unit mount to be identified. This identification is then associated with a measurement location.

[0020] In one embodiment according to the invention, it is provided that location information or a position specification is stored in the magnetically active region, which can be read by the sensor unit (2). Thus, an identifier can be reliably stored.

[0021] In an advantageous embodiment, the location information or position specification can be specified by positioning the magnetically active area on the sensor unit mount. Thus, numerous location information or position specifications can be displayed and selected.

[0022] In an advantageous embodiment, the sensor unit can store the location information or position information in a data memory. Thus, the location information or position information can be linked to other available measured values.

[0023] The location information or position information is preferably a measuring location at which a specific measurement of a parameter, for example a flow rate or a temperature, takes place.

[0024] Preferably, the sensor unit has a data memory in which the location information or position information can be stored. Additionally, measured values, such as a measured temperature or a measured pressure, can be stored in the data memory.

[0025] In an advantageous embodiment, the data memory can store the location information or position information and measured values. This allows historical measured values ​​and measuring locations to be easily and quickly retrieved and assigned.

[0026] In an advantageous embodiment, it can be provided that an additional sensor unit holder is designed to accommodate the sensor unit, which differs from the sensor unit holder in the magnetically active area. Thus, location information or position information can be easily and reliably encoded and stored in the magnetically active area.

[0027] In an advantageous embodiment, the sensor unit can have a measuring sensor separate from the magnetic field sensor. Thus, the sensor unit can measure multiple measured values ​​simultaneously.

[0028] In an advantageous embodiment, the sensor unit can be provided with an input unit and a display unit. The input unit can preferably be configured as buttons. The input unit can also be configured as a touchscreen. The display unit is preferably configured as a display. Thus, a user can reliably and quickly enter inputs into the sensor unit while simultaneously monitoring the display of a measured value.

[0029] To achieve the stated object, the invention provides the features of the independent claim directed to a method for recording measured values. In particular, to achieve the stated object, the invention proposes, in a method of the type described above, that a position of a magnetically active region on the sensor unit holder is detected during the recording, and that information corresponding to the position is stored with the measured values. Thus, automatic information about the measurement location can be provided in conjunction with information about the measured value.

[0030] In one embodiment of the invention, the sensor unit is attached to a further sensor unit holder for recording additional measured values, the magnetically active region of which is designed differently from that of the sensor unit holder. Thus, different measurement locations can be automatically provided.

[0031] The advantage of the invention is the automatic and reliable assignment of measured values ​​to the measuring location under changing and non-stationary conditions.

[0032] The invention will now be described in more detail using an exemplary embodiment, but is not limited to this exemplary embodiment. Further exemplary embodiments result from combining the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiment and / or the previously described variants of devices and methods according to the invention.

[0033] It shows: Fig. 1 one sensor unit and three sensor unit holders

[0034] In the following description of various embodiments of the invention, elements that correspond in their function are given the same reference numbers even if they have a different design or shape.

[0035] For clarity, not all reference symbols are shown in the figures, although the elements may very well be present in the figures. However, identical reference symbols indicate functionally and / or structurally identical components and functional units.

[0036] Fig. 1 shows a sensor unit 2 and three sensor unit holders 1. The sensor kit 11 comprises a sensor unit 2 and at least one sensor unit holder 1.

[0037] A sensor unit holder 1 comprises a vertical mounting opening 3, a horizontal mounting opening 4, and a magnetically active region 5. The mounting openings 3, 4 ensure that the sensor unit holder 1 can be mounted on a wall or other object. The magnetically active region 5 is preferably designed as a permanent magnet, which is glued, magnetically adhered, or detachably attached to the sensor unit holder 1.

[0038] The sensor unit holder 1 can be made of plastic. Alternatively, the sensor unit holder 1 can be made of metal.

[0039] The sensor unit 2 may be made of a plastic. The sensor unit 2 may also comprise a metallic material.

[0040] The three sensor unit mounts 1 differ in that the position of the magnetically active area 5 is different. The different positions of the magnetically active areas 5 encode specific and different measurement locations.

[0041] The sensor unit 2 comprises a magnetic field sensor 6, an input unit 7, a data memory 8, a separate measuring sensor 9, and a display unit 10. The magnetic field sensor 6 is preferably a Hall sensor. The input unit 7 can be one or more buttons, which can, for example, switch the sensor unit 2 on and off. The input unit 7 can also be a touchscreen or display. The sensor unit 2 further has a data memory 8. The display unit 10 can be a display and preferably shows a measured (current) or historical measured value.

[0042] The sensor unit holder 1 is designed to hold the sensor unit 2 in a defined position and / or orientation.

[0043] When the sensor unit 2 is brought close to the sensor unit holder 1 or is directly hung, the magnetic field sensor, in particular a Hall sensor, can read the location information or position information stored in the magnetically active area 5 of the sensor unit holder 1 and store it in the data memory 8. In addition, the sensor unit 2 has another separate measuring sensor 9 with which a parameter, such as temperature, pressure, or flow rate, can be measured. The parameter is also stored in the data memory 8. Thus, measurement location information can be stored and retrieved automatically and without user intervention.

[0044] In a sensor kit 11 with a sensor unit 2 and at least one sensor unit holder 1, wherein a magnetically active region 5 is formed on the sensor unit holder 1 and the sensor unit 2 has a magnetic field sensor 6, it is proposed that a relative position of the magnetically active region 5 to the sensor unit can be determined.
