The invention discloses an abnormal session analyzing method for website logs. The method comprises the following steps: forming an independent purpose access unit (for example a page, a picture, script access and the like) by a user session; in the initial analyzing stage, analyzing a normal session flow by way of combining modes for automatically accessing a website in the logs; continuously adding normal session streams in the subsequent processing process, and boiling down all sessions expect normal ones to abnormal sessions; and meanwhile, respectively displaying and processing the abnormal sessions in different levels. The method from the starting point of abnormality analysis can greatly improve the analyzing efficiency of the abnormality of the website logs without leaking any abnormal access sessions, so that the method is most valuable for safety / forensic application to analyzing hacking.

The embodiment of the present disclosure discloses an obstacle detection method and device, electronic equipment, vehicle-end equipment, an automatic driving vehicle, and a storage medium, and relates to the field of automatic driving. The specific implementation scheme is: collect the obstacle observation information sent by at least one sensor, and respond to the pre-stored obstacle tracking information including the same identification as the obstacle identification, the obstacle tracking information and the obstacle observation information with the same identification Carry out similarity calculation to obtain the first similarity. In response to the first similarity being greater than the preset first threshold, the corresponding obstacle tracking information is covered with the obstacle observation information corresponding to the same identifier that is greater than the first threshold. According to The current obstacle tracking information determines the relevant information of obstacles, and the cost of analysis and calculation can be saved by covering; and because the amount of analyzed information is reduced, noise information can also be reduced and the correlation of obstacles obtained can be improved. reliability of information.

The invention discloses a working mode analysis method of a complex power electronic converter. The working mode analysis method comprises the following steps that 1) elements contained in the converter are drawn into a tree diagram; 2) the elements in the tree diagram are classified into different grades; 3) the on-off state combinations possibly existing in all the switching elements in each stage are listed; 4) the on-off state combinations in each stage are overlapped with non-switching elements respectively; 5) different grades of elements are overlapped, and a new mode is obtained aftereach superposition is carried out; 6) screening is carried out on the model states, and invalid modes are removed; and 7) the effective modes are combined according to the actual current flowing condition, and the types of the effective working modes of the converter are obtained. All the working modes of the electric power electronic converter can be obtained, and the recognition of the modes iscomprehensive and simple, so that the method can be used for analyzing a circuit mode of a multi-switch power electronic converter.

The invention discloses a method, device, device and storage medium for judging abnormal data of telecontrol equipment, wherein the method for judging abnormal data of telecontrol equipment includes: collecting multi-frame initial messages returned by the telecontrol equipment, and the telecontrol equipment is set in a power plant or substation, used to realize the operation data acquisition, measurement and monitoring of power equipment in power plants or substations; determine the initial type of the initial message; obtain the characteristics with continuity that match the initial type of the multi-frame initial message; if the feature If it matches the preset target type, it is judged that the data returned by the remote control device is abnormal. Compared with the method of manually analyzing and judging the results of initial message parsing, it can effectively reduce the workload of monitoring personnel, and secondly, analyze and judge the collected initial messages in a more timely manner. Whether the returned data is abnormal, and then assist the monitoring personnel to monitor the operating status of the telecontrol equipment and the master station.

The present invention relates to a method and system for synchronizing internal and external network data. In the method, the following steps are included: the external network equipment analyzes and extracts the file information of the file, and stores it in a database table. If the file contains an attachment file, the attachment file is backed up. Go to the first path, enter the file name of the attachment file into the corresponding position of the file name field in the table, move the attachment file to the second path, otherwise, delete the file, export the newly added record in the table and save it and Send to the internal network device, and send the attached file under the second path to the internal network device; the internal network device saves the received record file and attached file to the database and the fourth path respectively; the external network and the internal network device respectively Display according to the information stored in the table corresponding to the file to be displayed in the corresponding database. The invention reduces the transmission amount of files, improves the transmission efficiency, reduces the analysis amount of files in the internal network equipment, and improves the data synchronization efficiency between internal and external network equipment.
