Method for navigating data in local caching, system and customer terminal device

The present invention discloses a method, a system and a customer terminal device for buffer memorizing the local navigation data, which aims at resolving the problems of the prior navigation device that the downloading speed is slow causing poor experience of the user. The method comprises the steps: the navigation data is stored in the server end in different layers and in different blocks, and each layer corresponds to different map scale, and the navigation data is classified into different sub-blocks in each layer, and an exclusive ID is calculated according to the layer level and the position of the sub-block at each layer; the downloaded navigation data is memorized at the navigation terminal in order, and the index for the navigation data is established according to the ID; the navigation terminal responds to the request of the user and calculates the ID according to the layer level and the position information in the request; the ID is searched in the local index, and if the index is found, the navigation data corresponding to the ID is obtained in the local area, and if the index is not found, the navigation data corresponding to the ID is downloaded from the server and is buffer memorized. The buffer memory method effectively resolves the problems of the communication navigation area that the bandwidth is limit, and the speed for the navigation terminal to download the navigation data from the server is slow, and improves the responding speed, and improves the application experience of the user.

Method for across-platform monitoring enterprise application system performance

The invention provides a method for realizing the cross-platform performance monitoring of a J2EE architecture enterprise application system, which is a real-time monitoring method with a B / S structure for a J2EE architecture. The method divides the realization of performance monitoring to the application system into three layers: a data acquisition layer, a data processing layer, and a data exhibition layer; an enterprise can define key performance indices (KPI) of the enterprise according to the demand of IT operation and maintenance management of the enterprise; the realization method also internally defines a set of key performance indices which meet the demand of a plurality of enterprises at the same time; a data analysis engine is used to analyze acquired data through the acquisition to needed performance data of the key performance indices, and an analysis result is sent for alarm notification. Most enterprise-level application systems are deployed under the complex environment of various platforms, such as Unix, Windows and linux; and the development of different monitoring softwares aiming at different platforms is a complex and huge job. The data acquisition layer of the method adopts universal interface technology, and can realize the performance monitoring to multi-platform databases and application middlewares.

Method and device for displaying picture elements

The invention provides a method and a device for displaying picture elements, and relates to the technical field of network. The method provided by the invention comprises the following steps: adding a mask layer when initially dragging action of a mouse is intercepted, creating a second picture element corresponding to a dragged first picture element on the mask layer, wherein the second picture element is an icon including content data of the first picture element; acquiring coordinates in a mouse moving procedure, and changing the coordinates of the second picture element along with changing of the coordinates in the mouse moving procedure; hiding the mask layer while bounce of the mouse is intercepted, exchanging the content data of the first picture element with the content data of a third picture element when the mouse is bounced to point the third picture element; and rendering and displaying picture elements which are acquired after an exchanging procedure again. According to the method and device provided by the invention, reflowing times are reduced; namely, the number of elements of position needs to be counted again; therefore, redrawing times are also reduced; an occupancy rate of system resource is reduced; and a use rate of a CPU (central processing unit) is also reduced.

Anti-noise method and device of touch screen

The invention provides a touch screen data processing method for inhibiting noise and a touch screen control device which applies the method. The method comprises the following steps: (1) receiving an analog signal of a touch screen, and sampling the analog signal of the touch screen to obtain a digital signal; (2) according to a sampling value, calculating a reference value corresponding to the sampling point; (3) comparing the sampling value and the corresponding reference value to obtain a deviation, and comparing the deviation with a preset threshold value; (4) if the deviation is smaller than the threshold value, keeping the sampling value, abandoning the sampling value if the deviation is greater than the threshold value, and replacing the sampling value with the corresponding reference value obtained by the calculation; and (5) applying the data obtained in the step (4) to touch information processing, and calculating a touch position. The method can effectively inhibit common-mode noise and improve the detection precision of a touch position. Compared with a traditional noise elimination method, the touch screen data processing method has the following outstanding advantages of being simple in calculation method, small in hardware resource occupation when a touch signal is realized and high in processing speed, is not affected by the length of a scanning signal and can calculate the signals of any length.

Audio and video synchronization method based on simplified timestamps

The invention relates to an audio and video synchronization method based on simplified timestamps, which comprises the steps that a counter is generated to serve as a timestamp supply source; the timestamps for an image inputted originally and audio are established independently according to frames; after audio and video frames are coded, the timestamps are typed into fixed fields of code stream frames; the frames are composited; when the code stream composite frames are received, the timestamps are extracted and decoded; recovery data and the timestamps are stored in buffer zone queues; when the audio is played, the empty and full degree of an audio buffer zone is monitored; if the degree exceeds a defined threshold, stepout in streams is adjusted by adopting audio skip frames or repeated frames; when a video is played, the video frames to be played currently are compared with the audio frames synchronized in the streams on the timestamps; and if a difference exceeds a set threshold, the stepout among the streams is adjusted by adopting video skip frames or the repeated frames. According to the method, a timestamp field is introduced; the stepout in the streams and among the streams is distinguished by the empty and full degree of the buffer zones and the difference of the timestamps; a global clock is not required; resource occupation is less; and the method is simple and efficient by utilizing the skip frames and the repeated frames to synchronize.
