Description

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

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

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

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

In accordance with at least one embodiment, the sensor system comprises at least one processing unit which is set up and intended 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 then to forward this data or a data record generated from the data to a CPU, in particular wirelessly, in particular the CPU being 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 set up and intended to be arranged on a surface of a usage object, in particular on the inner surface of a tire.

Previously known carrier materials, in particular those which are arranged within a tire, are namely not applied flexibly or bendably, but rather, for example, in the form of an adhesive layer and / or a substrate. However, it is now proposed here, instead of offering such a non-flexible and non-bendable carrier material, one which has flexible and bendable properties.

In this context, “flexible” means that the carrier material is at least in places flexible and thus 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. When arranged directly, 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 moisture values comprises at least a first step by means of which at least one sensor for measuring pressure and / or moisture 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 to 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 record generated from the data to a CPU, in particular wirelessly, in particular the CPU being a vehicle control unit acts, at least the sensor, but preferably also the processing unit, being arranged on a flexible and bendable carrier material, the carrier material being arranged on the surface of a usage object, in particular on the inner surface of a tire.

In accordance with at least one embodiment, the carrier material is a textile material, in particular a woven material.

For the purposes 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 electrically contacting the sensor and the processing unit are woven into the woven fabric. The electrical conductor tracks can therefore also be integrated in the fabric in addition to the usual fibers and fabric strands or can replace individual fabric strands that form the fabric 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 another energy generation element between the sensor and / or the processing element.

Depending on the spacing and properties of the individual threads (twisted, puffy, etc.), very loose fabrics, such as a bandage or sealing fabric such as brocade fabric, can be formed, because fabrics become longitudinally elastic due to rubber threads used as warp threads (more ribbons), or crimped and / or bulk yarns are used, they are tensioned, processed and contract in the idle state. Bulk 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 strip extension.

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

For example, a plurality of sensors are arranged one behind the other on the carrier material along the circumferential direction of the tire, each of the sensors separately measuring the pressure in the tire. Alternatively or additionally, at least one of the sensors arranged on the inner surface of the tire absorbs and measures forces acting on the outside of the tire. For this purpose, the sensor can, for example, be able to perceive and measure an expansion and / or compression caused by an 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 permitting conclusions about the force acting on the outer surface of the tire (force duration, 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 external force can be measured by the sensor. The CPU of the device claimed here can then use algorithms correspondingly stored in the CPU to determine a force value of the external force at a specific measurement time from the elongation and / or compression values of the tire inner surface and / or from the changing tire inner 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 circumferential direction. It is also conceivable that at least one sensor records a pressure value in a rotation pattern of less than 10 degrees and at most 30 degrees if the tire is rotated.

Furthermore, the present invention relates to a sensor arrangement for measuring and / or processing measured pressure and / or moisture values.

The sensor arrangement described comprises at least one sensor for measuring pressure and / or moisture as well as 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 utility object, 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 comprises the CPU described.

Furthermore, the present invention relates to a control system for measuring and / or processing measured pressure and / or moisture 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 Embodiments described above, wherein the carrier material is arranged on the inner surface of the tire, that is to say inside the tire.

At least one of the sensors is arranged, for example, on the inner surface of the tire and measures forces acting on it from outside the tire. For this purpose, the sensor can, for example, be able to detect an expansion and / or compression, caused by an external force applied to an outer surface of the tire, the inner surface of the tire is perceived and measured. For example, the carrier material can then be designed to be stretchable and / or flexible, with expansion and / or compression of the carrier material permitting conclusions about the force acting on the outer surface of the tire (force duration, 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 inflated pneumatically. For example, the tire is a vehicle tire.

In accordance with at least one embodiment, the control system comprises at least one tire valve, which is part of the tire, the evaluation unit being integrated on or in the tire valve.

In particular, it can be provided that the evaluation unit is integrated in 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 includes the processing unit in this embodiment.

In accordance with at least one embodiment, the control system comprises at least two tires which can be mounted or mounted on a vehicle, at least one sensor arrangement according to at least one of the above-described embodiments being arranged in each of the two tires and 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 which has been previously programmed into the CPU and / or into the evaluation unit and / or processing unit. The zero position can be, for example, a position in which the tire valve described above reaches the greatest height with respect to a support base. The support floor can be a road on which the tire can rotate about the axis.

In accordance with at least one embodiment, each rotational position of each sensor is transmitted to the CPU, so that the CPU continuously or discretely detects a relative position of the tires with respect to one another and / or a rotational angular velocity, a rotational acceleration of each of the tires and / or a radial / axial acting on each of the tires Force captured. 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 stability control system, ABS, trans control systems to improve and / or safeguard driving behavior, especially in curves.

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

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 mains power supply.

Alternatively or additionally, the generation of electrical energy for supplying the sensor and / or processing unit by means of so-called "energy harvesting" is possible.

Energy harvesting is the extraction 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 referred to as nanogenerators. Energy harvesting avoids restrictions due to wired power supply or batteries in wireless technologies.

• - 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.

Possibilities of energy harvesting:

• - Piezoelectric crystals generate electrical voltages when subjected to force, for example by pressure or vibration. These crystals can be arranged on or on the carrier material;
• - Thermoelectric generators and pyroelectric crystals extract 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 generating 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 has no energy store) with electrical energy.
It is also conceivable for the energy storage unit (s) of the processing unit (s) to supply the CPU with electrical energy in whole or in part. For example, the CPU cannot be connected to any other energy storage devices and / or power supply lines.

At least one of the energy stores can be charged via the above-mentioned energy harvesting.

The energy transfer between the sensors and / or the processing units and / or the CPU can take place in whole or in part wirelessly.

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

For example, the wireless energy transmission between the individual elements takes place 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 a, in particular the, in particular flexible, support material, with at least one dielectric layer between the electrodes is arranged.

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

For example, in a tire, two or more processing units and / or two or more processing units of different tires communicate with each other.

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 for one or more of the processing units to represent the master, which controls the other processing units (slave) and / or the other sensors (slave).

For example, one of the processing units and / or the CPU, after the device has been started up (for example after the device has been switched on), can select sensors which are put into operation for a predefinable useful life. 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 data of a predetermined one Number (i.e. less than all sensors) of sensors forwarded to the CPU (filtering).

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

Another alternative or in addition is conceivable that one or all 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 separate, network segments (VLANs) by means of at least one VLAN switch, and each of the detection elements depending on the activation 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 as claimed here, individual processing units and / or sensors can then be categorized in a particularly simple manner (according to different priorities etc.). In one embodiment, a “virtual”, that is to say VLAN, subdivision is therefore chosen instead of a physical network subdivision. This ensures that changes in the categorization of the processing units and / or sensors can be reacted to particularly quickly and without complex conversion work.

In accordance with at least one embodiment, the control system comprises at least one processing network, wherein at least one VLAN switch of the processing network can be subdivided into at least two, only logically separate, network segments (VLAN), and each processing unit and / or each of the sensors is dependent can be controlled by 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 separation model is clear and straightforward and has been used for years. However, this has the disadvantages that broadcast requests in the subnet are visible to all participants and would have to be considered by the endpoints. In other words, different end devices could previously only be controlled via corresponding, 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 dispensed with, so that a single physical structure can be used for the entire network, this physical structure, i. H. Network architecture, only on the basis of a logical, in particular also a mathematical distinction (i.e. thought).

The abbreviation "VLAN switch" designates 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 in the form of a VLAN network, make it possible for the separation of the network to be divided 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 separated by VLANs. The data stream of each station is provided with an identifier (the VLAN "Tag"). This identifier determines the association of a data packet with 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.

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

In particular, it is pointed out that the VLAN technology described here can be one which is adapted to the industry 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 expression "tagged" is derived from the English expression "material tags".

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

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

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

This has the advantage that, as a rule, already existing, older switches can 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, 3 bits for the priority field, 1 bit for the Canonical format indicator and 12 bits for the VLAN ID.

To uniquely identify a VLAN, each VLAN is first assigned a unique number. This number is called 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, ...

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

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 in accordance with the aforementioned IEEE 802.1Q standard are available per network segment via the control device.

If a network segment which has been assigned a specific VLAN ID uniquely, preferably uniquely, has a higher priority than a, only in logical terms, a different network segment of a correspondingly different VLAN ID, the control device and / or the VLAN switch should be provided to prefer first the data exchange of the higher priority network segment in order to allow processing of the lower priority network segment only after the tasks assigned to this higher priority network segment have been completed.

In other words, the following generally applies: assignment and configuration of the OPC UA endpoints to a specific network segment in accordance with the VLAN ID and assignment of a priority in accordance with 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, unique, preferably unambiguous, VLAN ID, with at least one control element via each of the VLAN IDs is controllable. According to at least one embodiment, at least one device comprises at least one temperature sensor, wherein the temperature sensor measures 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.

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

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

The invention is described in more detail below on the basis of an exemplary embodiment and the associated figures.

The shows 1 an embodiment of a sectional view of a tire proposed here within which the arrangements proposed in this application are arranged.

The 2nd shows two tires that can be mounted on a vehicle and are in data communication with each other via the common CPU.

The same or equivalent components are provided with the same reference numerals, even if some reference numerals or some components are exaggerated.

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.

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

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

Along the inside 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 in the form of a carrier strip so that the sensors 1 and the processing unit 2nd are arranged one behind the other along the main strip extent.

The carrier strip on which the sensors 1 and the processing unit 2nd are arranged forms in the 1 a median strip, which is to the left and right of other 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 on an inner surface of the side wall 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 even 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 unit, which in particular is wireless from at least one evaluation unit 3rd whose data is received and processed.

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

In the CPU 4th A certain number of maximum angular velocities 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 such a number is exceeded, the CPU can 4th indicate to the vehicle user that a tire 100 needs to be replaced and / or that the tire 100 must be refilled with compressed air.

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