Telemetry radio-frequency power and frequency controller and operation method thereof

Abstract

The invention discloses a telemetry radio-frequency power and frequency controller which comprises an FPGA chip, a control switch, an interface chip, a power supply chip, a crystal oscillator and a base. The interface chip, the FPGA chip and the crystal oscillator are all connected with the power supply chip. The interface chip is connected with the FPGA chip. The interface chip and the FPGA chipare bidirectionally communicated. The FPGA chip is connected with the crystal oscillator. The FPGA chip is connected with a dial switch, a power selector switch, a confirmation setting switch and an LED indicator. According to the invention, the controller can be applied to a telemetry product which needs to change the transmission power level and the transmission frequency; control steps can be greatly simplified; when transmission power and a frequency point are controlled, the dial switch of the controller is adjusted to a needed value; remembering relevant control commands is not needed; unsuccessful transmission power and frequency point control caused by an instruction transmission error or a serial port software setting error is prevented; the controller is small in size and convenient to carry; and a user simply needs to carry the controller and related cables when controlling the transmission power and the frequency point of the telemetry product.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a remote measurement radio frequency power and frequency controller and an operating method thereof. Background technique [0002] In telemetry products, it is often necessary for test and debuggers to control the radio frequency transmission power and transmission frequency point of the telemetry microwave module according to requirements. Usually use a desktop computer or a portable computer to send relevant control instructions to the telemetry module through the corresponding serial port debugging software to control the relevant transmission power and frequency point. This method has the following disadvantages: at the same time, each time the control of the transmission power and frequency points also requires the test and debugging personnel to enter the relevant sending instructions in the computer serial port debugging software, which is cumber...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: at the same time, each time the control of the transmission power and frequency point needs to be tested and debugged by the tester to enter the relevant sending instructions in the computer serial port debugging software, which is cumbersome

When there are many frequency points to be controlled, since the control commands of different frequency points are different, it is easier to make mistakes

And in some special application places such as confidential places, it is not allowed to use computers, resulting in the inability to control the radio frequency transmission power and transmission frequency point of the telemetry microwave module
