The invention relates to the technical field of environmental analysis, and discloses a new pollutant identification method and device, computer equipment and a storage medium, and the method comprises the steps: determining a target execution strategy through determining the application sequence of each non-target analysis method and each computational toxicology method in a high-throughput fusion method; the method can be realized by reasonably selecting and switching execution strategies whether searching corresponding chemical substances from the toxic effect or evaluating the toxic effect of the chemical substances from the found chemical substances. Furthermore, a target execution strategy is utilized to perform new pollutant risk assessment and calculate a plurality of risk values, various characteristics of the new pollutants and performance in an actual environment are comprehensively considered, and the potential risk of the new pollutants can be quantitatively reflected from different angles. And finally, multiple target new pollutants are further determined in combination with multiple risk values, and objects which have great threats to the environment and human health and need to be managed and controlled preferentially are screened out from numerous possible new pollutants.

A bridge damage information collection device based on piezoelectric effect comprises a shock wave receiving sensor, wherein the signal output end of the shock wave receiving sensor is connected to the signal input end of a front-end conditioning circuit, the signal output end of the front-end conditioning circuit is connected to the signal input end of a data acquisition module, and the signal output end of the data acquisition module is connected to the signal input end of a host computer; the shock wave receiving sensor collects internal reflection waves of the bridge under external excitation through the bridge; the shock wave receiving sensor collects the internal reflection waves of the bridge under external excitation and converts them into electrical signals, then amplifies, filters, and performs over-current and over-voltage protection on the electrical signals through the front-end conditioning circuit, and then converts the analog signals into digital signals through a digital-to-analog conversion module in the data acquisition module and sends them to the host computer; the present invention can complete the flaw detection inside the bridge without damaging the bridge structure, and has the characteristics of safety and convenience.

The present invention discloses an integrated drilling tool for drilling, sampling and real-time measurement, which is applied to the fields of geological exploration, geophysical exploration engineering, space drilling, etc., and uses a drill bit to complete the sampling of the required strata while drilling, so as to obtain a new type of drill bit structure with low disturbance and in-situ samples, and realize the real-time acquisition requirements of information and data of the strata information of the hole wall, physical and mechanical properties related parameters, etc. while taking out the samples, so as to achieve the efficient and reliable goal of integrated drilling, sampling and measurement. The integrated drilling tool of the present invention combines the measuring component with the part of the drill rod close to the drill bit. When drilling normally, the measuring component does not work, and rotates with the drill bit to ensure the progress of drilling and sampling; when drilling is completed, the measuring component pops out to the hole wall, and while the drill is lifted upward, the measuring component performs testing or data acquisition in real time on the hole wall, so that the integration of drilling, sampling and real-time measurement can be realized, with high efficiency, good accuracy, short cycle and low cost.
