Definitions
- scavenger systems which generate energy due to the rotation and vibration of the tyre.
- the tyre vibration accelerates a mass in combination with a spring.
- the moving mass can for instance be a magnet inside a coil, which generates a voltage due to the magnet movement.
- PZT piezo-type
- Another way is to apply piezo-type (PZT) material in the spring, which generates a voltage when stressed (See US 7467034 B2 and US 2008/0047363 Al).
- PZT piezo-type
- the proposed system can generate sufficient power at lower rotation speeds. Also it can be very small and be placed in remote locations.
- the invention describes a system where a sensor system inside a tyre needs to be provided with electrical power.
- the sensors measure for instance acceleration, temperature, pressure and strain.
- the measured data are transmitted via an RF-link.
- the power for the system needs to be supplied without any galvanic connections. Poor solutions are scavengers which use the rotation and vibrations in the wheel. A better solution with more constant power is inductive power transfer.
- FIG. 1 Location send and receiver coil is shown in FIG. 1. Space limitations in a car system are shown in FIG. 2. The preferred locations for the sending coil are marked.
- Feature 1 Special send coil construction and orientation as shown in the FIG. 1
- the send coil is placed perpendicular to the tyre and as close as possible to the tyre. This generates a better field inside the tyre and therefore a better coupling factor to the receive coil in the tyre.
- Coils are supported with a partial ferrite core. This reinforces the magnetic field generation. It also makes the coil properties less dependent on the environment. Metallic objects in the neighborhood of the coil can influence the inductance of the coil.
- the ferrite core partly functions as a shield and keeps this inductance more constant.
- Feature 2 Special receive coil construction and orientation The receive coil is placed perpendicular to the tyre as shown in FIG. 1. The field at the centre of the tyre is main parallel to the tyre as shown in FIGS 3, 4 and 5.
- FIG. 5 shows the send coil perpendicular to tyre, with ferrite support/shielding.
- FIG. 6 shows the tyre and the receive (pick-up) coil inside the tyre.
- the send coil has a driver operating on a certain frequency -
- the driver has an optional resonant circuit
- the receive coil has a rectifier-conditioner for generating the proper DC- voltage
- FIG. 7 shows schematically how is the power transferred from the send coil to the receive coil by magnetic induction.
- FIG. 8 shows the generated power as function of the arrangement. It shows that there is a small angle which generates most of the power. This measurement is based on a continuous power level in the send coil. A better overall efficiency can be achieved by only turning the coil on in case that the receive coil is in close proximity. Required for this is a communication path from the receiver to the sender. It is possible to do this via a RF-link (which is already foreseen for transmitting the sender data). This is schematically shown in FIG. 9. Another way is to use the inductive path in 2 modes, one mode for sending energy and the other mode for a returning signal that power is generated at a sufficient level. This is schematically shown in FIG. 10.
- the operation mode of the system could look as following.
- the sender sends a small test burst to investigate if power is received at a certain.
- the sender will generate a full period burst.
- the full period bursts will stop as soon as no sufficient power receive signal is generated. This is schematically shown in FIG. 11.
- FIG. 12 shows the send coil
- FIG. 13 shows the position of the send coil and the receive coil in the test system.
- FIG. 14 shows the position of the send coil and the receive coil wherein the receive coil is placed in the tyre.
- FIG. 15 shows the position of the send coil in respect to a car.
