    摘要: A telemetry unit (100) is provided for mounting to the inside of a pneumatic tire, which includes sensors for measuring the pressure and temperature within the tire and an RF transmitter for transmitting measured data to an on-board display remote location. The unit (100) includes a piezoelectric element (114) supported in a housing (112) with an actuator (136) arranged for contact with the element (114), to deflect the element (114) in response to external forces acting on the actuator (136) during rotation of the tire. For every rotation of the tire, cyclic pulses of electrical charge are generated by the deflection of the element (114). The unit (100) includes control means which controls the consumption of stored charge when measuring and transmitting data and is arranged to vary the rate of transmission of data from the unit (100) in dependence on the rotary speed of the tire.

    摘要: Low power consumption protocol A telemetry unit (100) is provided for mounting inside a pneumatic tire, which includes a piezoelectric element (114) supported in a housing (112), with an actuator (136) arranged for contact with the element (114), to deflect the element (114) in response to external forces acting on the actuator (136) during rotation of the tire. For every rotation of the tire, cyclic pulses of electrical charge are generated by the deflection of the element (114). The charge is stored and utilised under a power consumption protocol including the steps of: initiating power to a data measurement circuit for measuring data from the environment local to the unit (100); disabling power to the data measurement circuit; initiating power to a data transmission circuit; transmitting data from the measurement circuit; and disabling power to the transmission circuit. The power consumption protocol therefore minimises consumption of the generated power, during measurement and transmission of data by the unit (100).
