1. A detection system for a composite detector, comprising: a composite detector, a constant-temperature box, a smoke generator, a standard gas storage tank, a gas collection device and a laser Raman spectroscopy analyzer, wherein
the constant-temperature box is sealed, and both the composite detector and the gas collection device are arranged in the constant-temperature box;
the smoke generator, the standard gas storage tank and the laser Raman spectroscopy analyzer are all arranged outside the constant-temperature box;
the constant-temperature box, the smoke generator, and the standard gas storage tank are used to simulate a battery thermal runaway environment,
the laser Raman spectroscopy analyzer receives gas from the gas collection device for detection and obtains a first detection data of the gas, the composite detector obtains a second detection data, and
by comparing and analyzing the first detection data with the second detection data, the composite detector is calibrated, and a qualitative and quantitative detection result is obtained.
