Description

The present invention relates to a method for measuring and / or processing measured pressure and / or humidity values according to the respective preamble of claim 1.

The method proposed here comprises at least one sensor for measuring pressure and / or humidity. The sensor can be one which is based on a mechanical, thermoelectric, resistive, piezoelectric, capacitive, inductive, optical and / or magnetic operating principle.

For example, the sensor proposed here can be a pressure and / or a humidity sensor. In particular, the sensor can also be an inclination sensor, a force sensor, a CCD sensor, a photo cell, a Hall sensor or a thermocouple.

Different operating principles can also be connected to one another, so that a sensor is created which, for example, is based on both capacitive operating principles and based on an optical operating principle.

According to at least one embodiment, the sensor system comprises at least one processing unit which is set up and provided to control the sensor and / or to store and / or process data measured by the sensor.

Furthermore, the sensor system comprises at least one evaluation unit which evaluates the data forwarded to it by the processing unit in order to then forward this data or a data set generated from the data to a CPU, in particular wirelessly, in particular where the CPU is a vehicle control unit acts.

The CPU can be part of the sensor system.

According to the invention, at least the sensor, but preferably also the processing unit, is arranged on a flexible and bendable carrier material, the carrier material being designed and intended to be arranged on a surface of an object of use, in particular on the inner surface of a tire.

Previously known carrier materials, in particular which are arranged within a tire, are namely neither applied in a flexible nor bendable manner, but rather, for example, in the form of an adhesive layer and / or a substrate. However, it is now proposed here, instead of such a non-flexible and non-bendable carrier material, to offer one which has precisely flexible and bendable properties.

“Flexible” in this context means that the carrier material is at least in places flexible and therefore elastic.

The carrier material therefore adapts to the shape of the inner surface of the tire. The carrier material is preferably arranged directly or indirectly on the inner surface of the tire. In the case of a direct arrangement, the carrier material is in direct contact with a rubber of the tire.

According to at least one embodiment, the method proposed here for measuring and / or processing measured pressure and / or humidity values comprises at least a first step by means of which at least one sensor for measuring pressure and / or humidity and at least one processing unit is provided, the sensor is set up and provided to control the sensor and / or to store and / or process data measured by the sensor.

In a further step, at least one evaluation unit is provided, which evaluates the data forwarded to it by the processing unit and then forwards this data or a data set generated from the data to a CPU, in particular wirelessly, in particular where the CPU is a vehicle control unit acts, wherein at least the sensor, but preferably also the processing unit, are arranged on a flexible and bendable carrier material, the carrier material being arranged on the surface of an object of use, in particular on the inner surface of a tire.

According to at least one embodiment, the carrier material is a textile material, in particular a woven material.

In the context of the invention, a woven fabric is therefore a fabric that has been woven manually or by machine on the basis of individual threads.

For example, electrical conductor tracks for making electrical contact with the sensor and the processing unit are woven into the woven fabric. The electrical conductor tracks can therefore also be integrated in the tissue in addition to the usual fibers and tissue strands, or they can replace individual tissue strands which form the tissue network.

These conductor tracks can therefore represent an electrical connection between the sensor and the processing unit. The conductor tracks can also form an electrical connection between a battery or some other energy generating element between the sensor and / or the processing element.

Depending on the distance and properties of the individual threads (twisted up, fluffy, etc.), very loose fabrics, such as bandages or sealing fabrics such as brocade fabric, can be created, because fabrics are made longitudinally elastic by means of rubber threads used as chain threads (more ribbons), or crimps and / or or bulk yarn, they are stretched, processed and contract when at rest. Bulky yarns consist of textured, i.e. crimped synthetic fibers. The crimp changes the properties of the synthetic fibers. The yarns spun on it are very elastic and voluminous and have good thermal insulation.

According to at least one embodiment, the carrier material is designed in the form of a carrier strip, so that the sensor and the processing unit are arranged one behind the other along the main extent of the strip.

The "main extent of the strip" is that length dimension and length direction of the carrier material which represents a main direction of extent. Compared to the length of the carrier material in the direction of the main extent of the strip, a width of the carrier material is therefore negligible.

For example, several sensors are arranged one behind the other on the carrier material along the circumferential direction of the tire, each of the sensors measuring the pressure in the tire separately. Alternatively or additionally, at least one of the sensors arranged on the inner surface of the tire receives forces acting on the tire from outside the tire and measures them. For this purpose, the sensor can, for example, be able to perceive and measure an expansion and / or compression, caused by external force applied to an outer surface of the tire (for example the tread), of the inner surface of the tire. For example, the carrier material can then be designed to be stretchable and / or flexible, with expansion and / or compression of the carrier material allowing conclusions to be drawn about the force acting on the outer surface of the tire (duration of force, force level in Newtons, etc.). For this purpose, an expansion and / or compression of the inner surface of the tire and / or an internal air pressure that changes due to an external force can be measured by the sensor. The CPU of the device claimed here can then use algorithms stored in the CPU to determine a force value of the external force at a specific measurement time from the expansion and / or compression values of the tire inner surface and / or from the changing tire pressure. However, it is also possible that at least one sensor. This measurement can take place simultaneously or with a time delay. For example, everyone records a pressure value at the lowest and / or highest point of the tire in the direction of rotation. It is also conceivable that at least one sensor records a pressure value in a rotation grid of less than 10 degrees and at most 30 degrees if the tire is rotating.

The present invention also relates to a sensor arrangement for measuring and / or processing measured pressure and / or humidity values.

The described sensor arrangement comprises at least one sensor for measuring pressure and / or humidity and at least one processing unit which is set up and provided to control the sensor and / or to store and / or process data measured by the sensor.

At least the sensor, but preferably also the processing unit, are arranged on a flexible and bendable carrier material, the carrier material being set up and intended to be arranged on the surface of the one object of use, in particular on the inner surface of a tire.

The sensor arrangement proposed here comprises the same advantageous configurations and advantages as the sensor system described above.

The sensor system differs from the sensor arrangement in particular in that the sensor system additionally includes the CPU described.

Furthermore, the present invention relates to a control system for measuring and / or processing measured pressure and / or humidity values within a tire, the control system described here comprising an at least partially inflated tire, in particular a vehicle tire, and at least one sensor system according to at least one of the The embodiments set out above, wherein the carrier material is arranged on the inner surface of the tire, that is to say in the interior of the tire.

At least one of the sensors is arranged, for example, on the inner surface of the tire and measures those acting on the tire from outside Forces on. For this purpose, the sensor can, for example, be able to perceive and measure an elongation and / or compression, caused by external force applied to an outer surface of the tire, of the inner surface of the tire. For example, the carrier material can then be designed to be stretchable and / or flexible, with expansion and / or compression of the carrier material allowing conclusions to be drawn about the force acting on the outer surface of the tire (duration of force, force level in Newtons, etc.).

The control system described here therefore has the same advantages and advantageous configurations as the sensor arrangement described above and the sensor system described above.

The tire is therefore preferably a pneumatic tire which is pneumatically inflated. For example, the tire is a vehicle tire.

According to at least one embodiment, the control system comprises at least one tire valve, which is part of the tire, the evaluation unit being built into or integrated into the tire valve.

In particular, it can be provided that the evaluation unit is built into a cover element or on a cover element of the tire valve so that the evaluation unit can be screwed onto the thread of a valve rod. The cover element can be one or a part of a valve cap of the valve that can be attached to the valve rod.

Such a valve cap therefore already comprises the processing unit in this embodiment.

According to at least one embodiment, the control system comprises at least two tires that can be or are mounted on a vehicle, with at least one sensor arrangement according to at least one of the embodiments presented above being arranged in each of the two tires and with all data being transmitted to the common CPU.

The control system preferably comprises only a single CPU which is responsible for all arrangements.

According to at least one embodiment, the evaluation unit transmits a rotational position of the sensor relative to a zero position of the tire to the CPU.

The zero position can be an initial rotational position about the main axis of rotation of the tire that has been previously programmed into the CPU and / or into the evaluation unit and / or processing unit. The zero position can, for example, be a position in which the above-described tire valve reaches the greatest height relative to a support base. The support floor can be a road on which the tire can rotate around the axis.

According to at least one embodiment, each rotational position of each sensor is transmitted to the CPU, so that the CPU continuously or discrete-time records a relative position of the tires to each other and / or an angular velocity, a rotational acceleration of each of the tires and / or a radial / axial acting on each of the tires Force recorded. Horizontal and / or vertical (shear) forces and tire air pressure can also be recorded.

For example, the measured information is used as input information for the stability control system, ABS, transcontrol systems to improve and / or safeguard driving behavior, in particular when cornering.

In this respect, by means of the CPU proposed here and its preferably wireless communication with the individual evaluation units, which are preferably installed in the tire valves, it is proposed which summarizes all tires in a technical overview.

The sensor and / or the processing unit and / or the CPU can be supplied with electrical energy by means of a battery or a fixed line power supply.

Alternatively or additionally, it is possible to generate electrical energy to supply the sensor and / or processing unit by means of so-called “energy harvesting”.

Energy harvesting refers to the production of small amounts of electrical energy from sources such as ambient temperature, vibrations or air currents for mobile devices with low power. The structures used for this are also known as nanogenerators. With wireless technologies, energy harvesting avoids restrictions due to wired power supply or batteries.

• - Piezoelektrische Kristalle erzeugen bei Krafteinwirkung, beispielsweise durch Druck oder Vibration, elektrische Spannungen. Diese Kristalle können an oder auf dem Trägermaterial angeordnet sein;
• - Thermoelektrische Generatoren und pyroelektrische Kristalle gewinnen aus Temperaturunterschieden elektrische Energie. Diese Generatoren können an oder auf dem Trägermaterial angeordnet sein;
• - Über Antennen kann die Energie von Radiowellen, eine Form von elektromagnetischer Strahlung, aufgefangen und energetisch verwendet werden. Ein Beispiel dafür sind die passiven RFIDs. Diese Antennen können an oder auf dem Trägermaterial angeordnet sein;
• - Photovoltaik, elektrische Energie aus der Umgebungsbeleuchtung;
• - Osmose.

Energy harvesting options:

• - Piezoelectric crystals generate electrical voltages when a force is applied, for example through pressure or vibration. These crystals can be arranged on or on the carrier material;
• - Thermoelectric generators and pyroelectric crystals generate electrical energy from temperature differences. These generators can be arranged on or on the carrier material;
• - The energy of radio waves, a form of electromagnetic radiation, can be captured and used energetically via antennas. Passive RFIDs are an example of this. These antennas can be arranged on or on the carrier material;
• - Photovoltaics, electrical energy from ambient lighting;
• - osmosis.

For example, such an energy storage and / or energy generation element is also arranged on the carrier material in order to supply the sensor and / or the processing unit with electrical energy.

An energy store of the device can be part of a processing unit. For this purpose, one or more of the processing units can have such an energy store (local energy store). For example, only one or some of the processing units have such an energy store, so that one of these processing units supplies another processing unit (namely one which does not have an energy store) with electrical energy.

It is also conceivable that the energy storage unit (s) of the processing unit (s) fully or partially supplies the CPU with electrical energy. For example, the CPU cannot be connected to any other energy stores and / or energy supply lines.

At least one of the energy stores can be charged via the aforementioned energy harvesting.

The energy transfer between the sensors and / or the processing units and / or the CPU can take place entirely or partially wirelessly.

The wireless energy transmission in the near field, also known as non-radiative coupling, includes, for example, inductive coupling based on magnetic flux. The term wireless energy transmission is often used synonymously for inductive energy transmission, as this plays a dominant role in practical applications. Wave phenomena play no role in the non-radiating coupling in the near field.

For example, the wireless energy transfer takes place between the individual elements by means of inductive coupling, resonant inductive coupling and / or capacitive coupling.

For example, the sensor is constructed as follows and comprises at least one capacitor with at least two electrodes, which are arranged, in particular in a horizontal direction along and on one, in particular the, in particular flexible, carrier material to one another, with at least one dielectric layer between the electrodes is arranged.

The sensor is characterized in that at least one at least partially moisture-permeable and / or moisture-absorbing moisture layer is arranged at least in places on a side facing away from the carrier material, at least one electrode and / or the dielectric layer, with the at least one electrode and / or the dielectric layer in a transverse direction between the carrier material and the moisture layer, so that a capacitance changes at least partially due to the moisture at least partially hitting the dielectric layer, a processing unit being set up and provided to measure and / or store this change, so that a capacitive humidity sensor is created.

In the context of the present application, “moisture-absorbing layer” can be understood to mean an at least partial absorption of moisture from an ambient medium into the layer itself. Moisture can therefore be understood as a gaseous or droplet phase in the surrounding medium. The moisture can be contained in the ambient air or some other ambient medium of the layer.

The water or liquid content of air is generally referred to as humidity. The absolute humidity indicates how much water or liquid vapor is contained in the volume unit of the gas mixture; Unit of measurement: g of water (or other liquid) · m-3. The relative humidity is the quotient of the amount of liquid vapor present in the gas at a certain temperature and the saturation amount of liquid vapor possible at the same temperature. The relative humidity is usually given in percent (%). To do this, the quotient is multiplied by 100. Is the air saturated, ie the Relative humidity is 100%, some of the liquid in the air is liquid. In this case, the associated liquid-gas mixture is referred to as haze or mist.

The term moisture or dampness can be the measure of the presence of water or another liquid in or on a material (e.g. textiles) or a substance or in a gas or in a room.

The moisture-absorbing moisture layer described here can therefore differ from a, in particular only liquid-absorbing (moisture) layer, among other things in that the moisture-absorbing moisture layer is made of a material which, in addition to adsorbing liquid, also absorbs moisture contained in the surrounding medium. However, it is also conceivable that the moisture-absorbing moisture layer merely absorbs moisture in the surrounding medium of the layer and therefore cannot absorb any liquid.

For example, two or more processing units and / or two or more processing units of different tires communicate with one another in one tire.

It is conceivable that the plurality of processing units form a processing network, the acquisition, processing and / or forwarding of the sensor data and / or the processing data of each sensor and / or each processing unit being controlled by at least one control device (master). The control unit can be identical to the CPU described above.

However, it is also possible that one or more of the processing units represent the master, which controls the other processing units (slaves) and / or the other sensors (slaves).

For example, one of the processing units and / or the CPU can, after the device has been put into operation (for example, after the device has been switched on), select such sensors which are put into operation for a predefinable period of use. Alternatively, all or some sensors can also be put into operation, but then it is conceivable that a processing unit and / or the CPU, in particular for the purpose of saving energy, only forwards data of a predetermined number (i.e. fewer than all sensors) from sensors to the CPU (Filtering).

This master processing unit can preferably communicate with the CPU as the only unit.

As an alternative or in addition, it is also conceivable that one or all of the processing units and / or a sensor (slave or master) communicate directly with the CPU.

According to at least one embodiment, the processing network can be subdivided into at least two, only logically separated, network segments (VLANs) by means of at least one VLAN switch and each of the detection elements depending on the control by a VLAN switch and / or the control device and thus by each of the network segments can be controlled.

If, for example, a very large area (for example a textile) is equipped with a large number of sensors and processing units used here, individual processing units and / or sensors can then be categorized in a particularly simple manner (according to different priorities, etc.). In one embodiment, instead of a physical network subdivision, a “virtual”, that is to say VLAN, subdivision is chosen. This is because this ensures that changes in the categorization of the processing units and / or sensors can be responded to particularly quickly and without costly conversion work.

According to at least one embodiment, the control system comprises at least one processing network, which can be subdivided into at least two, only logically separated, network segments (VLAN) by means of at least one VLAN switch of the processing network, and each processing unit and / or each of the sensors as a function can be controlled from the control by the VLAN switch through each of the network segments.

For this purpose, the VLAN switch can be installed in at least one of the processing units and / or sensors or in a separate component.

According to at least one embodiment, the VLAN switch is used to prioritize the individual network segments, in particular with regard to their data exchange.

According to at least one embodiment, each processing unit and / or each network segment is assigned at least one VLAN ID, with at least one sensor or another processing unit being controllable via each of the VLAN IDs. Individual sensors and / or individual Processing units can form their own sub-network.

In order to communicate across network boundaries, static project-dynamic routes are used in the prior art. This model of separation is clear and straightforward and has been used for years. However, this has the disadvantage that broadcast requests in the subnet are visible to all participants and must be viewed by the endpoints. In other words, until now, different end devices could only be controlled via corresponding, separate and physically separate switches assigned to each subnet. However, such a structure is particularly expensive and extensive in design.

As already mentioned above, the design of each subnetwork with a separate switch and separate physical data lines is therefore especially dispensed with, so that a single physical structure can be used for the entire network, this physical structure, i. H. Network architecture, is only separated on the basis of a logical, in particular also mathematical, distinction (i.e., thought).

The abbreviation “VLAN switch” denotes such a network switch, which is set up and intended to operate a network in the form of a Virtual Local Area Network (VLAN).

In this respect, the network segments now claimed, which can each be designed in the form of a VLAN network, make it possible for the separation of the network to be subdivided into several logical segments, that is to say the network segments.

In contrast to the physical separation through the assignment to a switch port, the devices are logically separated by a VLAN ID when they are separated by VLANs. The data stream of each station is given an identifier (the VLAN “tag”). This identifier determines whether a data packet belongs to a specific VLAN. All devices with the same VLAN ID are now in a logical network.

In particular, a broadcast can be limited by the logical separation of the individual networks. Broadcasts are only distributed to members of the same VLAN and not to all control elements attached to the switch.

This not only contributes to higher performance, but also to more security, because the data traffic is restricted to fewer addressees. In addition, users or the control elements in a VLAN usually have no way of breaking out of the assigned VLAN. Access (or attack) to another computer that does not belong to your own VLAN can therefore be prevented by the network switch. If cross-VLAN communication is necessary, routes can be set up for this purpose.

In particular, it is pointed out that the VLAN technology described here can be one which is adapted to the industrial standard IEEE 802.1Q and / or is compatible with it.

The IEEE 802.1Q standard is a prioritization and VLAN technology standardized by the IEEE, which, in contrast to the older, only port-based VLANs, implements packet-based tagged VLANs. The term “tagged” is derived from the English term “material tags”.

Tagged VLANS are therefore networks that use network packets that have a special VLAN marking.

In particular, data fields for V-LAN tagging are defined in the 802.1Q standard that can be introduced in the data area of an Ethernet packet.

To this extent, the present network can be designed in the form of an Ethernet communication system.

This has the advantage that existing, older switches can usually also forward such packets. The inserted tag usually consists of several fields, for example four fields with a total length of 32 bits.

2 bytes are used for the protocol ID and for the priority field 3rd Bit, for indicator of the canonical format 1 Bit and used for VLAN ID 12 bit.

In order to clearly identify a VLAN, each VLAN is first assigned a unique number. This number is called the VLAN ID. A detection module that is equipped with VLAN-ID = 1 can communicate with any other device in the same VLAN, but not with a device in another VLAN, e.g. B. ID = 2, 3, ....

In order to differentiate between the VLANS, an Ethernet frame is extended by 4 bytes according to the IEEE 802.1Q standard. Of these, 12 bits are provided for the VLAN ID, so that (without Using the canonical format) 4096-2 = 4094 VLANS are theoretically possible.

It is conceivable that the individual logical network connections according to an OPC standard, i. H. for example in the form of OPC UA connections. In particular, it is conceivable that several OPC UA endpoints with different IP addresses, VLAN IDs and prioritization according to the above-mentioned IEEE 802.1Q standard are available per network segment via the control device.

If a network segment that has been assigned a specific VLAN ID unambiguously, preferably unambiguously, has a higher priority than a network segment that differs therefrom, only in logical terms, with a correspondingly different VLAN ID, the control device and / or the VLAN switch can be provided to initially prefer the data exchange of the higher-priority network segment in order to allow the lower-priority network segment to be processed only after the tasks assigned to this higher-priority network segment have been dismantled.

In other words, the following generally applies: Assignment and configuration of the OPC UA endpoints to a specific network segment according to the VLAN ID and assignment of a priority according to the priority of the corresponding VLAN.

According to at least one embodiment, each sensor and / or each processing unit is assigned at least one VLAN ID and each network segment is in turn assigned at least one, for example exactly one, unambiguously, preferably one-to-one, VLAN ID, with at least one control element over each of the VLAN IDs is controllable. According to at least one embodiment, at least one device comprises at least one temperature sensor, the temperature sensor measuring an ambient temperature and / or a temperature of a sensor and forwards it to the processing unit of a device and / or to the central CPU.

According to at least one embodiment, the central CPU determines a degree of utilization (CPU load and / or memory consumption) of at least one processing unit, whereby when a limit temperature of the processing unit and / or at least the sensor assigned to this processing unit is exceeded, its performance is at least partially throttled or switched off completely.

In addition, it is additionally or alternatively conceivable that the evaluation unit (s) communicate with one another and are interconnected in the same way as the processing unit in the sense of the above network.

In the 1 is, as mentioned above, a sectional view of a tire proposed here 100 shown, being inside the tire 100 a sensor system 2000 for measuring and / or processing pressure and / or moisture values is shown.

It can be seen that the sensor arrangement 2000 a variety of sensors 1 for measuring pressure and / or humidity, with sensors for these 1 a preferably single processing unit 2 is provided, which is set up and provided for the sensors 1 to be controlled and / or by the sensors 1 store and process measured data.

Both the sensors 1 as well as the processing unit 2 are on a flexible carrier material 11 arranged, the carrier material 11 is set up and provided for this on the surface of an object of use, in the present case therefore on an inner surface of the tire 100 to be arranged.

Along the inner surface of the tire 100 , i.e. parallel to the circumferential direction of the tire 100 on the inner surface of the tire 100 , is the carrier material 11 designed in the form of a carrier strip, so that the sensors 1 and the processing unit 2 are arranged one behind the other along the main extent of the strip.

The carrier strip on which the sensors 1 and the processing unit 2 are arranged, forms in the 1 a central strip, which is to the left and right of further optional carrier strips, which can be designed in the same way as the central carrier strip.

It is also shown that another optional carrier strip is on an inner surface of the sidewall of the tire 100 can be arranged. This carrier strip can also be constructed in the same way as described above. For example, it is possible that only a single carrier strip is inside the tire 100 on an inner surface of the tire 100 is arranged.

The sensor arrangement 2000 includes a CPU 4th external of the tire 100 , for example in a vehicle interior, in particular which is provided as a vehicle control device, which in particular is wireless from at least one evaluation unit 3rd receives and processes their data.

For example, the CPU 4th determine on the basis of the processing of the data whether the internal tire pressure is sufficient or whether it relates to a previous period of use of the tire 100 tire wear 100 is likely. It is also conceivable that the data also include or should only consist of such data which are caused by external forces acting on the tire from the outside. In particular, the CPU 4th on the basis of the evaluation unit 3rd generated and supplied data are calculated whether a predetermined maximum load duration of the tire 100 is exceeded. This maximum load duration may, for example, refer to such a past period according to the data on a rotational angular speed and a rotational acceleration of the tire 100 and / or one on the tires 100 acting forces result.

In the CPU 4th A certain number of maximum rotational angular speeds and / or rotational accelerations or on the tires can be stored in advance 100 acting radial forces related to a given period of use. If this number is exceeded, the CPU 4th indicate to the vehicle user that a tire 100 needs to be replaced and / or that the tire 100 needs to be refilled with compressed air.

Furthermore, in the 2 at the same time a control system 3000 shown, which in the present two tires 100 is installed and via a common CPU 4th are in data communication with each other.
