Missile-borne telemeter with record function

Abstract

The invention discloses a missile-borne telemeter with a record function. The missile-borne telemeter comprises a telemetering power source and a power source management module, wherein the telemetering power source is connected with the power source management module and used for providing a working power source for the missile-borne telemeter. The missile-borne telemeter further comprises a signal conditioning module, a signal collecting and converting module, a collecting and editing module and a transmitter, wherein the signal conditioning module is electrically connected with the signal collecting and converting module, the signal collecting and converting module is electrically connected with the collecting and editing module, and the collecting and editing module is electrically connected with the transmitter. The missile-borne telemeter further comprises a record storage module electrically connected with the collecting and editing module. Collected data are stored and backed up, the back-up data can be read when landing to be recovered without being affected by electromagnetic interference, the telemetering data can be obtained through wireless transmission and recovery of the back-up storage data, and therefore the reliability of data obtaining is improved.

Description

technical field [0001] The invention relates to a bomb-borne telemeter, in particular to a bomb-borne telemeter with a recording function. Background technique [0002] The on-board telemeter is the core equipment of the on-board telemetry system, which is used to collect various working parameters of the projectile before launch and during flight. The telemeter frames the collected data and serializes the framed data. The binary code stream is formed by chemical processing, which is transmitted by the transmitter to the ground telemetry receiving equipment in real time through the wireless channel, so as to analyze and judge the operating status of the system on the missile. [0003] The transmitter performs radio frequency modulation on the serialized framed data of the missile-borne telemeter. The modulated signal is transmitted through the antenna and received by the antenna of the ground receiver. The receiver demodulates the received radio frequency signal and restores...

AI Technical Summary

Problems solved by technology

[0005] The measurement data of the traditional missile-borne telemetry instrument only relies on the wireless channel to transmit the collected data in real time, and the wireless signal transmission is easily affected by environmental electromagnetic interference. When the transmission process is subjected to electromagnetic interference, the telemetry data cannot be transmitted reliably, which will cause some telemetry data Error or loss, the integrity of the telemetry data cannot be guaranteed, which affects the comprehensive analysis of the working status of the missile system
