Air traffic collision avoidance method based on state prediction

ActiveCN106548661AReduce the probability of flight conflictsReduce the number of timesAircraft traffic controlState predictionComputer science
The invention discloses an air traffic collision avoidance method based on state prediction. The method comprises the following steps: continuously detecting motion state information of all current planes in a local air space through a native plane; calculating the flight condition of all the planes in a specified length of time in the future according to the motion state information of all the planes, and screening out a target plane approaching the native plane; judging whether the target plane and the native plane pose a conflict risk, and sending traffic alert information if there is a conflict risk; and judging whether the target plane and the native plane posing a conflict risk pose a collision threat, and sending decision warning information and providing a collision avoidance decision if there is a collision threat. According to the invention, the flight condition of all the planes in a specified length of time in the future is observed continuously, a target plane approaching the native plane is screened out, whether the target plane and the native plane pose a conflict risk or a collision threat is judged, and a collision avoidance decision is provided. Thus, the probability and frequency of flight conflict are reduced effectively, and the safety of flight is ensured.

Method for multiple virtual machines to access distributed object storage system

The invention relates to a method for accessing a distributed object storage system through a mode of designing a local cache in a client under the architecture of the distributed object storage system. The method comprises a reading operation: when reading the object file data of the distributed object storage system, firstly, searching an object file in the local cache of the client, if the object file is not searched in the local cache, reading the object file from the distributed object storage system, storing in the local cache system of the client, if the object file is searched in the cache, not reading the object file from the distributed object storage system; writing operation: when writing object field data in the distributed object storage system, firstly writing the object file data in a local cache, after finishing writing, marking that the object file is not synchronized, returning, and then writing the object file data written in the local cache in the distributed object storage system by a cache synchronous service module. Through the invention, the number of access times to the distributed object storage system can be reduced; the I/O throughput of accessing the file system by the virtual machine is improved; and the response time of an access request is reduced.

Page resource loading method and terminal equipment

The invention provides a page resource loading method and terminal equipment. The page resource loading method and the terminal equipment are applicable to the technical field of mobile application. The method comprises the steps of intercepting a page loading request when a page loading event is triggered, and obtaining a page address carried by the page loading request; determining a page resource plug-in matched with a site based on the site corresponding to the page address, wherein the page resource plug-in is prestored in an installation package of an application program; running the page resource plug-in to obtain multiple static buffer resources which are stored locally under the site; loading the static buffer resources matched with the page address according to a preset network view in the application program. By means of the page resource loading method and the terminal equipment, even on the condition that a page resource is loaded at the first time, a Hybrid App can stillquickly load the page resource from the local, thus the frequency of requesting to a second server for the page resource is reduced, the time consumed for loading the page resource is greatly shortened, and the performance of the Hybrid App is improved.

Multi-electrode ablation catheter

The invention relates to a multi-electrode ablation catheter which comprises a catheter, electrodes distributed on the catheter, a wire connected onto the electrodes to transmit signals and radio frequency energy and a handle used for adjusting the shape of the catheter. The electrodes comprise basket-shaped electrodes and head electrodes arranged at the farthest end of the catheter. The catheter comprises a basket-shaped section with the basket-shaped electrodes, a flexible transition section and a main body section coupled to the handle, wherein the basket-shaped section is formed by a center catheter and a plurality of branch catheters evenly distributed around the center catheter and connected with the center catheter at two ends. The basket-shaped electrodes are formed by electrodes distributed on the branch catheters, and contracting, base state and stretching of the branch catheters relative to the center catheter are achieved by controlling the handle. The catheter can be contracted to conveniently enter the renal artery vessel to be transferred to the position nearby a target spot of a complex structure, the catheter can extend after the catheter reaches the place to cling to the vessel wall completely, protrusions are not formed in the middle, the problem that the vessel is irritated to be narrow due to the fact that a certain position is ablated too much is solved, and blood flow of the renal artery is not affected.
