Telemetering system power supply device and control method for testing rotating member

Abstract

The invention provides a telemetering system power supply device and control method for testing a rotating member. According to the power supply device, a control panel is connected with a battery through lead bonding, wherein the control panel comprises a microcontroller, a circuit protection unit, a first linear voltage regulator, a second linear voltage regulator, a switch control unit, a hallswitch sensor and an indicator light; the microcontroller senses a magnetic field change through the hall switch sensor, outputs a control signal to the switch control unit and carries out real-time indication on the working state through the indicator light; and the microcontroller, the circuit protection unit and the first linear voltage regulator are combined to provide the control panel with apower supply. The control method comprises the steps of collecting magnetic intensity signals; screening data; outputting a control signal; and carrying out battery state monitoring and state indication. A difficulty in power supply control on the battery of a telemetering system rotating part for the rotating member is avoided, the design difficulty of hardware is reduced, the volume of the hardware is reduced, the power consumption of the hardware is reduced and the stability and the interactivity of the device are improved.

Problems solved by technology

[0002] At present, imported or domestic multi-channel telemetry systems have been applied in the parameter test of aero-engine rotating parts. Domestically, inductive power supply is generally used to provide non-contact power supply to the rotating part of the telemetry system. Its advantage is that it can be used for a long time. Continuous power supply, the disadvantage is that the power supply distance is limited (usually not greater than 5mm), and the installation structure is complicated

For some aeroengines with large axial movement of rotating parts, limited installation space of telemetry system, or aero-engines that require rapid installation of telemetry system, the form of inductive power supply cannot meet the test requirements

At present, some telemetry systems have adopted a battery-powered solution. Since the installation space of the rotating part of the telemetry system is very limited during the engine test, and it is not allowed to modify the hardware after installation, the usual method is to directly turn on the battery for output. This power supply method makes the battery utilization rate very low and uncontrolled
