The invention provides a wear-leveling method and a wear-leveling device for a memory system and a non-volatile memory, wherein the non-volatile memory comprises a plurality of data blocks and a linked list which is formed by the plurality of data blocks. The wear-leveling method comprises the following steps: firstly, a step of shift operation, namely the plurality of data blocks are arranged in order according to time values respectively corresponding to the plurality of data blocks and according to the time order of the time values, so as to form the linked list; and secondly, a step of erasure judgment, namely judgment is made whether to erase the plurality of data blocks, and when the plurality of data blocks are erased, corresponding data blocks are selected for erasure according to the time order of the time values of the plurality of data blocks in the linked list. The wear-leveling method and the wear-leveling device can simultaneously give attention to the system efficiency and the wear-leveling effect while really reflecting the service life of the erasable blocks in a system.

The invention relates to a coat and cap characteristics and attitude detection-based traffic police detection method and system. The system comprises an offline training construct classifier, an online real-time detection traffic police and an attitude thereof, wherein an offline part extracts a pedestrian hog characteristic, a cap hog characteristic, a fluorescent clothes hog characteristic, a construct pedestrian classifier, a cap classifier and a fluorescent clothes classifier through a lot of collected sample images respectively; and an online part collects an original image in real time and judges whether a pedestrian, namely the traffic police who wears the cap and fluorescent clothes at the same exists in the original image or not by the pedestrian classifier, the cap classifier, the fluorescent clothes classifier and various combinations, then judges the attitude of the traffic police, and prompts a driver to help the driver correctly understand the attitude of the traffic police. The detection method is broadly divided into two processes of accurate matching and fuzzy matching; the two processes can be corroborated by each other; the traffic police and the attitude thereof can be accurately and quickly detected; and the coat and cap characteristics and attitude detection-based traffic police detection method and system have important guiding significance in active driving.

The invention discloses a method for transmitting data in an opportunity network. The method comprises the following steps: adding a base station in the opportunity network to acquire, process and analyze data information, designing a source node recommendation strategy based on geographic positions, motion features and reputation values, dynamically regulating the quantity of resources shared by a data demand node sending a resource request through reputation feedback and updating node reputation values according to the document similarity, so that the decay rate of edge node reputation values is retarded on one hand, and higher matching requirements are provided for a community active node on the other hand. According to the method disclosed by the invention, the resource utilization rate and the transmission efficiency are effectively improved, and the transmission efficiency and the success rate are greatly improved on the premise of reducing the time delay and the resource consumption.

The present invention discloses a modular integrated multi-stage and multi-drive chamber partially non-coaxial dry type vacuum single pump, which comprises a plurality of modular vacuum drive chambers. The dry type vacuum single pump is characterized in that the plurality of modular vacuum drive chambers are integrated as an overall single pump. The plurality of modular vacuum drive chambers are connected in series to form a multi-stage vacuum single pump. At least two vacuum drive chambers, among the above plurality of modular vacuum drive chambers, are associated in the two non-coaxial manner, wherein the gas mainstream direction is perpendicular to the drive shaft of a rotor. The inlet of a first-stage vacuum chamber is directly introduced to the atmosphere. According to the technical scheme of the invention, the plurality of modular vacuum drive chambers are non-coaxial, so that the compression ratio of each vacuum drive chamber is adjustable. In this way, in the high-vacuum environment, the compression ratio is large. In the rough vacuum environment, the compression ratio is small. Therefore, both the safety and the efficiency are given consideration to, and the optimized control is enabled. The differential pressure sharing and the heat sharing at each stage are more uniform.
