Description

Sensor system for measuring and / or processing measured pressure and / or humidity values based on ambient humidity

description

The present invention relates to a sensor system for measuring and / or processing measured pressure and / or humidity values as well as a sensor arrangement and a control system according to the respective preambles of claims 1, 4 and 5.

The sensor system 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 set up and intended to be arranged on a surface of a user 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 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 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.

With direct arrangement, the carrier material is in direct contact with a rubber of the tire.

According to at least one embodiment, the sensor system for measuring and / or processing measured pressure and / or humidity values 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.

In addition, the sensor system comprises at least one evaluation unit which evaluates the data forwarded to it by the processing unit and then evaluates them Forwards data or a data set generated from the data to a CPU, in particular wirelessly, in particular where the CPU is a vehicle control device, wherein according to the invention at least the sensor, but preferably also the processing unit, are arranged on a flexible and bendable carrier material, with the carrier material is set up and provided to be arranged on a 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 material. The electrical conductor tracks can therefore additionally be integrated into 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 (upturned, 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 bulky yarns are used, they are tensioned, 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 of the inner surface of the tire, caused by an external force applied to an outer surface of the tire (for example the tread). For example, the carrier material can then be designed to be stretchable and / or flexible, with an 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 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 circumferential direction. 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 as well as at least one processing unit which is directed 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 aligned 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 refinements 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.

The present invention also 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 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 forces acting on the tire from outside. 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, 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, which can be mounted or mounted on a vehicle, with at least one sensor arrangement according to at least one of the above-presented embodiments 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 programmed into the CPU and / or into the evaluation unit and / or processing unit about the main rotational position. act on the axis of the tire. The zero position can be, for example, a position in which the above-described tire valve reaches the greatest height to a floor. 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 among each other and / or an angular velocity, a rotational acceleration of each of the tires and / or a radial acting on each of the tires / axial force he records. 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 built into 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 landline 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.

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 Trä germaterial;

- 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 further 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 referred to as non-radiative coupling, includes, for example, the inductive coupling, based on the magnetic Flow. The term wireless energy transfer is often used synonymously for inductive energy transfer, as this plays a dominant role in practical applications. With the non-radiating coupling in the near field, wave phenomena play no role.

For example, the wireless energy transfer 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 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 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 moisture at least partially hitting the dielectric layer, a processing unit being set up and provided to measure and / or to measure this change save, 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 in the Unit volume of the gas mixture is included; Unit of measurement: g 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. If the air is 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 the adsorption of liquid, also contains moisture in the surrounding medium absorbed. 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, after the device has been put into operation (for example after the device has been switched on), can 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 send data from a predetermined number (i.e. fewer than all sensors) from sensors to the CPU forwards (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 can be controlled by each of the network segments.

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”, ie VLAN, subdivision is chosen. 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 can be controlled by each of the network segments depending on the control by the VLAN switch. 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 end points. In other words, until now, different end devices could only be controlled via corresponding switches that were assigned to each subnet, separate and physically separate from one another. However, such a structure is particularly expensive and extensive in design.

As already mentioned above, the design of each sub-network 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. 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 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 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 greater 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 explicitly for this.

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

The IEEE 802.1 Q 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 802.1 Q 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, 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 therefore initially 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 802.1 Q 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 certain VLAN ID unambiguously, preferably unambiguously, has a higher priority than a network segment that differs from it, only in logical terms, with a correspondingly different VLAN ID, the control device and / or the VLAN switch can be seen to initially allow the data exchange of the higher-priority network segment prefer 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 general rule is: 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 each of the VLAN IDs at least a control 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, with at least part of its performance when a limit temperature of the processing unit and / or at least the sensor assigned to this processing unit is exceeded wise throttled or completely switched off.

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.

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

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

FIG. 2 shows two tires which can be mounted on a vehicle and are in data communication with one another via the common CPU. Identical or identically acting components are provided with the same reference symbols, even if some reference symbols or some components are shown in an exaggerated manner.

As mentioned above, FIG. 1 shows a sectional illustration of a tire 100 proposed here, with a sensor system 2000 for measuring and / or processing pressure and / or moisture values being shown within the tire 100.

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

Both the sensors 1 and the processing unit 2 are arranged on a flexible carrier material 11, the carrier material 11 being set up and intended to be arranged on the surface of an object of use, in the present case on an inner surface of the tire 100.

The carrier material 11 is designed in the form of a carrier strip 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, 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 a central strip in FIG. 1, which can be left and right of further optional carrier strips, which can be formed in the same way as the central carrier strip.

It is also shown that a further optional carrier strip can be arranged on an inner surface of the side wall of the tire 100. This carrier strip can also be constructed in the same manner as described above. For example, it is also possible for only a single carrier strip to be arranged in the interior of the tire 100 on an inner surface of the tire 100. The sensor arrangement 2000 comprises a CPU 4 external to the tire 100, for example in a vehicle interior, in particular which is provided as a vehicle control device which, in particular, wirelessly receives and processes data from at least one evaluation unit 3.

For example, on the basis of the processing of the data, the CPU 4 can determine whether an internal tire pressure is sufficient or whether the tire 100 is likely to wear in relation to a previous period of use of the tire 100. 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, on the basis of a past period of use, the CPU 4 can calculate on the basis of the data generated and supplied by the evaluation unit 3 whether a predetermined maximum load duration of the tire 100 has been exceeded. This maximum load duration can result, for example, from 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 a forces acting on the tire 100.

Stored in advance in the CPU 4, a certain number of maximum rotational angle speeds and / or rotational accelerations or radial forces acting on the tire 100 can be based on a predetermined period of use. If such a number is exceeded, the CPU 4 can 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, a control system 3000 is shown at the same time in FIG. 2, which is installed in the present two tires 100 and is in data communication with one another via a common CPU 4.

A sensor arrangement 2000, as described above, is installed within each of the tires 100.
