The method provides a method for accessing a shared data structure by multiple threads in parallel in parallel applications, which comprises the following steps: authorizing a lock of the shared data structure to one of the multiple threads; executing the operation of the thread which acquires the lock on the shared data structure; caching the operations of the threads which do not acquire the lock in the multiple threads; and in the subsequent time period in which another thread in the multiple threads acquires the lock of the shared data structure, executing the cached operations on the shared data structure. By utilizing the method, when the shared data structure is locked by one thread, the operations of other threads which do not acquire the lock of the shared data structure can be automatically cached; and when another thread acquires the lock of the shared data structure, all the cached operations can be executed, thereby obviously reducing the number of movements of elements in the shared data structure when modifying the shared data structure, and enhancing the performance of the multiple thread accessing. The invention also provides a corresponding device.

The invention discloses a drawing device for environmental art, relates to the technical field of environmental art, and mainly solves the problem that when a pencil is used for drawing, the sheet isstained due to the movement of a ruler. The device mainly comprises a work table on which a holding mechanism, a limiting mechanism, a cleaning mechanism, a lighting mechanism, a ruler moving mechanism, and a positioning mechanism are arranged. When in use, the ruler is pressed downward to drive a moving plate to move spring thimbles downward. The spring thimbles on the two sides can prevent the ruler from moving. The scribing position can be determined by a positioning pin lifting in a positioning cylinder. The drawing device has the beneficial effects that by preventing the ruler from moving, the graphite line on the drawing can be prevented from being driven to slide, so that the drawing is clean. When the ruler needs to be moved, the ruler can be jacked up by the spring thimbles, so that the movement is convenient.

The invention is applicable to the field of video monitoring, and provides a focusing method. The method comprises the following steps: after a focusing motor moves, obtaining the definition corresponding to the current position; determining change information of the definition according to the definition, wherein the change information comprises a target change rate and / or a continuous change frequency; if the preset termination condition is not met, determining the moving direction and the moving step length of the next time of movement according to the change information, and controlling the focusing motor to execute the next time of movement according to the moving direction and the moving step length; if the preset termination condition is met, taking the position with the maximum definition as the focusing position. According to the scheme, the moving direction and the moving step length of the next moving can be determined according to the target change rate and / or the continuous change frequency, the position with the highest definition can be found more quickly, the moving frequency is reduced, and therefore the focusing efficiency is improved.
