The invention discloses a bayonet precise positioning capturing method and device based on a multi-target radar, and relates to the technical field of video monitoring. The method comprises the stepsthat a plurality of lane boundary lines of a multiple lane are projected into a radar coordinate system of the radar, lanes are automatically divided after lane boundary line information in the radarcoordinate system is acquired, radar triggering positions of the lanes in the radar coordinate system are acquired by mapping video triggering lines of the lanes into the radar coordinate system, accordingly the lane information and whether a bayonet capturing unit is triggered to capture or not can be rapidly judged according to detected target information output by the radar and transformed to be the information in the radar coordinate system, and if capturing occurs, captured information is output. The method and device provided by the invention avoid the defects of traditional video triggering capturing, and achieve precise capturing. Meanwhile, the defect that a traditional radar cannot differentiate and detect the target lane information is overcome.

The embodiment of the invention discloses a data source division method and device, equipment and a storage medium. The method comprises the steps of acquiring database information corresponding to multiple data sources; performing word segmentation processing on the database information corresponding to each data source, and determining a first feature set corresponding to each data source according to a word segmentation result; determining the similarity between every two data sources according to each first feature word in each first feature set, clustering each data source according to each similarity and a preset clustering algorithm, and determining each data source set; and when the number of the data source sets is equal to the number of the preset service directories, dividing each data source set to the corresponding preset service directory. Through the technical scheme of the embodiment of the invention, automatic and reasonable division of the data source can be realized,and the division accuracy is improved.

A signal processing method of a spectrum analyzer and the spectrum analyzer, the spectrum analyzer includes a radio frequency scanning module, a data acquisition module, a detection module, a display module and a control processing module, wherein the control processing module obtains the endpoints of a plurality of predefined scanning frequency bands Frequency and receive the scanning parameters input by the user, and determine the endpoint frequencies of multiple detection frequency bands according to the endpoint frequencies and scanning parameters of multiple scanning frequency bands. When it is detected that the endpoint frequency of the scanning frequency band does not coincide with the endpoint frequency of any detection frequency The endpoint frequency of the scanning frequency band sent to the radio frequency scanning module is adjusted, the endpoint frequency of the scanning frequency band is sent to the radio frequency scanning module, and the endpoint frequency of the detection frequency band is sent to the detection module, so that the radio frequency scanning module treats it according to the scanning frequency band determined by the control processing module The test signal is scanned so that the actual scanning frequency band matches the frequency range of the entire RF scanning and the data processing requirements configured by the user.
