The invention discloses a potential function-based method for identifying the malicious nodes of an intelligent electric meter system. The method comprises the following steps: dividing an intelligent electric meter into an electric meter to be measured and a witness electric meter; reflecting the characteristics of the positions of electric meter nodes by utilizing physical layer channel information; extracting the channel information of the electric meter to be measured by communication between the electric meter to be measured and the witness electric meter; calculating the position values of the electric meter to be measured according to the channel information; processing the position values by a potential function so that the potential function of the electric meter node reflects the position information of all electric meter nodes with the identity (ID) the same as that of the electric meter node; integrating the position values of all the electric meter nodes, thus realizing the identification of the malicious nodes of the intelligent electric meter system. The method is high in recognition rate; the calculation quantity and the additional communication rate of all intelligent electric meters are very low, and most calculation quantity is completed in a control center, thus the method is especially suitable for the intelligent electric meter system.

The present invention provides a method, device and system for air traffic controller fatigue detection, said method comprising: step 1, receiving control seat video monitoring data and land-air call data obtained by a real-time audio and video full data acquisition device; The video monitoring data of the control seats and the ground-air call data are detected and analyzed to obtain the controller fatigue index detection data; step 3, refer to the preset controller fatigue index detection data samples, and use the cluster analysis method to construct the controller's work status file In step 4, the controller fatigue index detection data in step 2 is classified and comprehensively detected, and if the similarity exceeds the threshold range, an alarm is triggered. The fatigue detection method can be applied in the field of air traffic control, and has strong practicability and operability.

The embodiment of the invention discloses an inundation sub-domain identification method and system, and relates to the technical field of computers. The inundation sub-domain identification method and system are applied to search engines. Inundation sub-domains are identified according to the dispersion or the concentration ratio of the fragment length of any valid fragment set of sub-domain names, and the identification degree of the inundation sub-domains can be effectively improved. The inundation sub-domain identification method in the embodiment includes the steps of collecting sub-domain names with the same main domain name, and if it is judged that the fragment length of any valid fragment set of the sub-domain names with the same main domain name is in dispersed distribution or concentrated distribution, identifying that the sub-domain names corresponding to any valid fragment set are the inundation sub-domains, wherein the valid fragment set is the same fragment set of a left-side domain name part and a right-side domain name part of the same-stage fragment in a same-stage fragment of the sub-domain names with the same main domain name.

An embodiment of the present invention provides an anti-cheating method and device for adaptive real-time video data, wherein the method includes: obtaining the IP address of the real-time video data and corresponding multiple playback users; The number of times of video playback within and the number of times of video playback of each user among the multiple playback users within the first preset period of time, respectively adaptively generate the first risk probability and the second risk probability; according to whether the first risk probability exceeds the first The preset threshold determines whether the IP address is a cheating IP, and whether the user is a cheating user is judged according to whether the second risk probability exceeds the second preset threshold; the cheating IP and cheating users are added to the blacklist database, and the cheating IP or cheating users are filtered out real-time video data. The embodiments of the present invention can effectively improve the degree of identification of whether real-time data is cheating data, reduce the possibility of misjudgment of large IP multi-users, and can effectively prevent high-risk playback users from cheating again.

The present application discloses an AR registration method and system. The method includes: extracting object feature information in a picture to be registered uploaded by an AR application; identifying the object feature information to obtain a classification level corresponding to the object feature information in the picture to be registered; Determine whether the classification level is greater than the preset level, if not, register the picture to be registered, if so, determine whether there is a registered picture in the AR server; if it is determined that there is a registered picture in the AR server, determine the registered picture and the pending Whether the object feature information in the pictures is the same, if so, register the picture to be registered. When the application initially registers an AR picture, if the AR picture cannot meet the registration requirements, it refers to the information of the registered picture in the AR server to improve the recognition degree of the object feature information in the picture to be registered, thereby improving the quality of the picture to be registered. Registration efficiency of registered images.

The invention discloses a carrier resource allocation system which comprises a carrier resource allocation device and a carrier resource controlled device, wherein the carrier resource allocation device is connected with the carrier resource controlled device by signals. The invention also discloses a method for allocating the carrier resources by applying the carrier resource allocation system and comprises the following steps that: step S1. the carrier resource allocation device sends a command generating identification codes into a covering device; step 2. the carrier resource controlled device in the covering device generates and sends the identification codes into the carrier resource allocation device; step three. the carrier resource allocation device sends the received identification codes and the corresponding carrier resource allocation information into the covering device; step four. the carrier resource controlled device compares the received identification codes and identification codes of the covering device; and if the identification codes are matched, the carrier resource of the covering device is allocated according to the allocation information. The carrier resource allocation system has the advantages of high identification degree, high safety, low cost, simple operation, convenient promotion, distribution reduction and the like.

The invention relates to a fault detection method and system for a direct current transmission line, belonging to the field of power system relay protection. The method firstly collects the single-ended electrical quantity data of the DC line in real time, and obtains the spatial modulus signal of the single-ended electrical quantity; calculates and obtains the accumulated quantity of the power transformation of the variation of the spatial modulus signal of the single-ended electrical quantity within the set time window, Construct a fault detection signal; continuously judge at least three adjacent fault detection signals, and judge whether they are all greater than the set detection threshold, if not, return to continue to collect and calculate the single-ended electrical quantity, if so, then the line is faulty and a protection is issued start signal.
