The rapid and simple data acquisition circuit is connected with a single-chip microcomputer and used for detecting pulse xenon lamp radiation signals. The data acquisition circuit comprises a precise integral amplification circuit, an analog-to-digital conversion circuit, a power supply module and a single-chip microcomputer control interface circuit. The precise integral amplification circuit is connected with the analog-to-digital conversion circuit so that analog-to-digital conversion is performed on the amplified radiation signals of the pulse xenon lamp. The single-chip microcomputer control interface circuit is connected with the analog-to-digital conversion circuit so that the pulse xenon lamp radiation signals are digitalized and then transmitted to the single-chip microcomputer through a shift register mode. The power supply module is electrically connected with the precise integral amplification circuit, the analog-to-digital conversion circuit and the single-chip microcomputer control circuit. According to the data acquisition circuit, the pulse xenon lamp radiation signals can be rapidly and accurately acquired, and precision is high and control is easy; and the circuit is high in anti-interference and anti-noise capacity so that the circuit can normally operate under the condition of severe environment.

Description

technical field [0001] The invention relates to a data acquisition technology, in particular to a pulse xenon lamp-based data acquisition circuit. Background technique [0002] Because the pulsed xenon lamp produces large light energy instantaneously, in view of this situation, the existing detection and sampling circuit cannot well adapt to the rapid changes in the radiation signal of the pulsed xenon lamp, and cannot quickly and accurately capture the higher radiation signal of the pulsed xenon lamp; moreover , the existing detection sampling circuit, its structure is relatively complex, resulting in the detected signal instability; thus making the single-chip microcomputer detection of pulsed xenon lamp radiation signal inaccurate. [0003] It can be seen that how to improve the detection accuracy of the single-chip microcomputer for the pulsed xenon lamp radiation signal is a technical problem that needs to be solved urgently in this field.
