The fuse chemical power source parameter infrared telemetering system comprises an infrared emission circuit, an infrared receiving pre-amplification circuit, a demodulation circuit, an acquisition card and a computer. The fuse chemical power source parameter infrared telemetering system has the advantages that fluctuation of voltages is reduced, the problem of secondary noise pollution is solved, signals can be accurately transmitted in a strong electromagnetic interference environment, it is guaranteed that broadband signals are accurately transmitted, and an infrared light path and an electromagnetic field do not affect each other, the problem of interference in telemetering is solved, the problem of boundary lines and multiple coefficients of two-channel transmission is solved due to the fact that alternating current signals and direct current signals are transmitted together through the same channel in an alternating current and direct current transmission mode, accuracy of signal conversion links is high, light emission parts are packed through an expanded plastic method, and it is guaranteed that the circuits and the components reliably work under the high overload condition.

Description

technical field [0001] The invention belongs to the technical field of fuze chemical power supply performance testing and relates to an infrared remote measurement system for fuze chemical power supply parameters. Background technique [0002] The chemical power sources (solid and liquid batteries) for fuzes need to be activated by the activation mechanism under high-speed rotation, and chemical reactions can generate electrical signals and work. [0003] According to the different forms of signal transmission, the previous performance testing methods include brush contact wired measurement, mercury collector ring wired measurement and radio telemetry. These methods have a limited test range and cannot be applied to new high-speed rotating machines with high speed and strong electromagnetic background interference. The contact measurement method has the disadvantages of low application speed, introduction of rotating background noise, easy wear, and poor contact. Mercury is...

These methods have a limited test range and cannot be applied to new high-speed rotating machines with high speed and strong electromagnetic background interference

The contact measurement method has the disadvantages of low applicable speed, introduction of rotating background noise, easy wear, and poor contact. Mercury is also toxic and not environmentally friendly. Radio telemetry also has the problem of background noise coupling, so that it cannot be accurately and precisely tested.
