Abstract

The invention discloses an automatic power-on device for a radiation anti-interference test of a forehead thermometer. The automatic power-on device comprises a timing control circuit, a single-chip microcomputer control circuit and a low-voltage pulse circuit, wherein the single-chip microcomputer control circuit generates a switch connection signal according to a time value set by the timing control circuit and outputs the switch connection signal to the low-voltage pulse circuit, and the low-voltage pulse circuit transmits a low pulse signa lto control a forehead temperature meter switch to be turned on before the forehead thermometer sleeps. The timing control circuit, the single-chip microcomputer control circuit and the low-voltage pulse circuit are arranged in a shielding shell, the forehead thermometer is arranged outside the shielding shell, and the low-voltage pulse circuit is connected to the forehead thermometer switch through a shielding wire. The whole automatic power-on device is arranged in the microwave anechoic chamber, the forehead thermometer can be always in a power-on state in the whole radiation anti-interference test, external electromagnetic interference is prevented from being introduced, and the accuracy of the radiation anti-interference test is improved.

Description

technical field [0001] The invention belongs to the technical field of performance testing of infrared temperature measuring devices, and in particular relates to an automatic start-up device for radiation immunity testing of forehead thermometers. Background technique [0002] In general, the forehead thermometer is equipped with a timed sleep function in order to save energy and electricity during use. For example, if there is no operation within 15-30 seconds, it will automatically shut down. However, in the radiation immunity test of forehead thermometer products, the forehead thermometer needs to be in the temperature collection state all the time to observe whether the forehead thermometer is working normally. However, personnel are not allowed to enter the microwave anechoic chamber during the radiation immunity test. [0003] At present, the following two methods are generally used in the radiation immunity test process to keep the forehead thermometer in the state ...
