Description

 Modular disk sensors Description The entire content of the priority application DE 20 2017 000 037.7 is hereby incorporated by reference in the present application.

The invention relates to a modular disk sensor system, in particular for mobile beds, in particular for use in the field of

Health care according to the preamble of the independent claim. The inventive modular disc sensor system consists of at least three modules which can be connected to one another in a plane in a washer-like geometry or be structurally coupled and at least one sensor carrier, at least one pressure sensor and at least one

Data communication unit has.

The inventive modular disc sensors are coupled to a mobile bed mechanically directly via the legs of a bed frame at the respective points of attachment of the respective legs to the rollers or differently shaped sliding or moving means. The measuring or sensor points of the pressure sensor are circular, spiral, meandering or raised on the

Surface or embedded in the structure of the pressure sensor.

Due to the system structure of the individual modules in a plane a very flat design is achieved, which correspond in geometry known washers with a central hole, eg for nuts / locknuts with screws and replace them by simple replacement, to pressure or temperature at fixations check. The replacement of existing washers or adapters for rolls or the like in conventional beds by the inventive modular

Disc sensors, which can also be used individually or in groups (diagonal or

Three-point support) can be done at any time, even without the use of tools possible.

The combination of existing washers with the inventive

Modular disc sensors are also easily configurable. The inventive modular disk sensor system is preferably designed at the measuring points for the measurement and transmission of parameters such as weight and temperature as well as their changes over time. In combination with the at least one data communication unit, are also relative

Speeds, acceleration and / or position determination in space possible.

The data communication unit communicates e.g. via ultra-wideband (UWB), WLAN, Bluetooth or other radio technology with suitable frequencies or with a Smart Beacon Device (SBD). Where the

Data communication unit integrated in the pressure sensor or sensor carrier or the pressure sensor or sensor carrier is integrated in the Smart Beacon Device (SBD).

Such smart beacon devices (SBDs) within the meaning of the invention are understood to mean communication units which, for example, can establish a bidirectional digital communication infrastructure by means of wireless low-energy Bluetooth and, in conjunction with a gateway, build interconnected networks which are also connected to the Internet via the gateway can. Each SBD can send and receive data and collect, store, process and transmit information via I / O ports / interfaces. In the case of the inventive modular sensor system, at least one SBD can be coupled to the pressure sensor or integrated into it in order to

Pressure sensor information on weight, temperature or their changes together with those determinable by the communication unit

 Velocity data, acceleration data and / or, in conjunction with the meshed network, to collect, store, process and, for example, positional data in space related to the measurement point. to a central

Data processing and control unit to submit.

For the purposes of the invention, coupling is understood as meaning the electrical, electronic and / or electromagnetic connection of the respective pressure sensor with parameters which can be tapped off in analogous and / or digitized form. Under integrable in the context of the invention, the constructive, structural

 Connection or union of the respective pressure sensor or sensor carrier understood with the SBD, which in the best case, no redundant components are required and a high structural integration of the inventive

modular disc sensor is achieved and the modules pressure sensor,

Sensor carrier and data communication unit are only functionally separable.

In inventive modular disc sensors are in this way by the

Use of suitable measuring point geometries at least following measurements feasible:

 Weight measurement as point measurement, line measurement, area measurement.

 Acceleration measurement as point measurement, line measurement, area measurement.

Temperature measurement as point measurement, line measurement, area measurement.

Position determination measurement in space as point measurement, line measurement, area measurement. The measurements are done in situ, sequentially or continuously, also in

Combination. The measurements themselves are regular or controllable. The

Measurement parameters themselves are able to regulate or control themselves as actuators. The connection of defined events of the measurements of the inventive modular sensor system to multimedia systems, such as image, video or the like, complement the possibilities of the invention.

SBDs can communicate with each other via the mesh network, as well as with the Internet. Thus, the requirements for "internet of the things (loT)" are met by the inventive modular sensor system.

Statistical analysis, trend analysis, pattern recognition and big data analysis are feasible with the use of the inventive modular sensor system. All user-specific data of the control and / or regulation are recorded, processed, documented and, if necessary, program-technically

encrypted and made accessible to authorized users via a portal or known communication channels available.

Due to its low energy consumption, a single-use SBD can communicate with one battery charge over a very long period of time - several weeks, months or even years - making it particularly suitable for wireless use.

The inventive modular disk sensors offer further possibilities for ensuring almost "lifelong" operation of sensors and SBDs, since the inventive modular sensor system is system-dependent through the active measurement of changes in parameters such as weight, temperature, and / or Acceleration also for energy harvesting to

Obtaining small amounts of electrical energy is designed, the inventive modular sensor system can simultaneously take over the power supply of one / several SBD. This can eg by tapping of energy to the sensors as energy converters that are temporarily not switched in the measuring mode.

This is a simple universally modular innovative modular

Disc sensor provided, which has a very flat design, which is easily adaptable to a number of bed roller systems.

From the prior art, a washer sensor is known which can be used as a safety and measuring system for vehicle technology, in particular for tightening of screw only when needed, especially in high pressure ranges, upon detection of the drop of a defined biasing force (see.

http://www.ist.fraunhofer.de/de/qeschaeftsfelder/maschinenbau Tools fahr zeuqtechnik / unterleqscheibensensorik.html: 12.12.201 6).

The invention has for its object to provide a modular disc sensors, for example, for mobile beds, which is easily adaptable to known mobile beds in the field of healthcare and in addition to the original function as a "washer" a measurement of status parameters of a patient bed, the detection of a Assignment, eg for presence detection, allows monitoring, eg parameter changes and / or position determination.

A further object is to provide a modular disk sensor system, for example for mobile beds, which can be exchanged or supplemented simply, quickly, service-friendly and inexpensively in an existing bed.

This object is achieved by the inventive device according to claim 1 and the embodiments according to the dependent claims. The inventive device claimed in claim 1 a

modular disc sensor (1), in particular for mobile beds, with at least three modules with at least one pressure sensor (2), at least one

Sensor carrier (3) and at least one data communication unit (4), which have a washer-like geometry.

Overall, the invention provides a multifunctional modular

Disc sensor provided especially for mobile beds, which can be easily and reliably integrated into existing systems with little installation effort.

Due to the simple geometries in the structure of the construction, these can be easily integrated into existing systems or retrofitted.

The modular disk sensors described herein are also used in other fields, e.g. in a trolley, laundry trolley, food trolley, desk chair, roll container, wheelchair, walker, IV pole or wash stand.
