A new architecture for implementing a time-resolved Raman spectrometer is 2-3 orders of magnitude faster than current systems. The system additionally is compact, environmentally rugged, low cost and can detect multiple components of a sample simultaneously. In one embodiment, the invention employs a rotating optical switch to time multiplex an input signal through multiple bandpass filters and into a single optical detector which is electrically activated only when the filtered input light pulse is about to impact it.The combination of time-multiplexing the input signal through multiple optical filters and time-sequencing the optical detector enables the device to detect and analyze 2-3 orders of magnitude faster than current designs, processing spectra within milliseconds instead of seconds. The system can process multiple material samples (25+) simultaneously, instead of sequentially, and its mechanical ruggedness and simplicity enables using the system in harsh physical environments when traditional spectrometers can not be used reliably.

The present invention provides a calibration method, device, system and storage medium of a data acquisition system. The method acquires multiple frame images captured by a photographing device in the calibration area by selecting the calibration area, and determines the corresponding object space points in the frame images. feature points with the same name to form a pair of feature points with the same name; according to the pair of feature points with the same name, the calibration parameters of the shooting device are determined. By determining the control plane in the calibration area, the fitting plane is fitted according to the laser point cloud collected by the scanning device; according to the matching relationship between it and the control plane, the calibration parameters of the scanning device are determined. According to the GNSS differential data, INS data, and odometer data of the POS system and the base station, the trajectory data of the POS system movement is determined; the target trajectory data is selected on the trajectory data according to the calibration area and the calibration point is determined on it, according to the adjacent calibration points The distance between them and the pulse number of the odometer of the POS system between adjacent calibration points determine the odometer calibration parameters.

The invention relates to the technical field of communication acquisition, and discloses an intelligent communication acquisition device with power supply control based on STM32, which includes an air conveying plate, a groove is opened on the top surface of the air conveying plate, and an elastic pad A is fixedly connected in the groove, and the elastic pad The top surface of A is fixedly connected with a pedal, and the top surface of the air transmission plate is fixedly connected with a fixed cylinder. Through the setting of the pedal, when the user steps on the pedal when passing through the equipment, the power supply mechanism is automatically activated to supply power to the body temperature detection mechanism, and then in use After the operator leaves the pedal, the body temperature detection mechanism will be automatically powered off, so as to achieve the benefits of saving electricity by starting the body temperature detection mechanism at an appropriate time. In addition, the operation of the device does not require additional power mechanisms and power sources, further saving energy and reducing The benefits of the complexity of the system also avoid the problem that the temperature accumulation caused by the continuous opening of the body temperature detection mechanism affects the service life.
