The invention discloses a method for optimizing B + tree index performance based on a persistent memory. A traditional B + tree index is designed according to the characteristics of a DRAM and a disk,the characteristics of long writing delay, limited writing times, inconsistent power-down data and the like of a persistent memory are not considered, and the performance of a direct migration indexcan be greatly reduced. In order to improve the index concurrency performance, reduce the writing frequency of a B + tree in a persistent memory and prolong the service life of the persistent memory,the method adopts an additional writing strategy for leaf nodes to perform delayed refreshing on internal nodes, and reduces a large amount of shift writes brought to maintenance of entry orderlinessin the insertion process; in order to further improve the indexing efficiency, lock-free search is adopted in internal nodes, multiple threads can access the same node at the same time, and the indexconcurrency is improved.

The invention relates to a community garage parking space management system including a license plate identification camera mounted at the entrance of a community, pressure sensors and infrared sensors mounted on different parking space in the community, and a timing device and an information recording module mounted in a guard room of the community. The license plate identification camera, the pressure sensors, the infrared sensors, the timing device and the information recording module are all in communicational connection with the central processor. The central processor is in communicational connection with a fixed storage and a temporary storage. The control processor is connected with an electric fence gate mounted at the entrance of the community, smart parking space locks mounted in the parking spaces of the community and a sound light alarm mounted in the guard room of the community in a controlling manner. The electric fence gate is in communicational connection with a remotecontroller. According to the invention, through the arrangement of the pressure sensors and the infrared sensors cooperating with each other, information about whether vehicles entering the communityare parked in assigned parking spaces or not can be acquired, so that random parking and illegal occupying of parking spaces in the community can be avoided.

The embodiment of the invention discloses a double-controller signal control device and method. A detection part receives a first level signal sent by a first controller and receives a second level signal sent by a second controller. A selection signal corresponding to the main controller is sent to the selector according to the level types corresponding to the first level signal and the second level signal. And the selector opens a corresponding data channel according to the selection signal so as to transmit the control signal sent by the main controller to the terminal equipment. Accordingto the technical scheme, the detection part determines the control power of the two controllers according to the level signal, the determination mode completely depends on hardware, and the delay caused by software control or the influence caused by unstable software operation can be effectively reduced. And moreover, the selector opens the corresponding data channel according to the selection signal, so that the competition danger situation is avoided. Through the cooperation of the detection part and the selector, the orderly management between the double controllers is realized.
