The invention discloses a micro-application / network transmission / physical (Micro-ANP) Micro-ANP communication protocol model architecture method of an underwater acoustic sensor network (UWSN). The method comprises three parts, i.e. Micro-ANP protocol stack hierarchy classification, Micro-ANP network transmission layer protocol composition and grouped format design, and the optimization of UWSN pack load length. Due to the concise protocol hierarchies and unique network grouping format of Micro-ANP, multiple addresses, first length, calibration, upper protocol type and other packaging, brought by a traditional hierarchy model, can be reduced, and the problems that in a sensor node, uplink protocol stacks cannot be too complicated due to computation, storage, energy and other extremely limited resources can be solved; and due to the optimized design of the UWSN pack load length, the energy and the consumption of end-to-end delay and other resources can be reduced, and simultaneously, the network throughput and the transmission reliability are improved. The Micro-ANP communication protocol model architecture method of the underwater acoustic sensor network is applicable to network communication of underwater data acquisition, environment monitoring, disaster prevention, resource monitoring and other application based on the UWSN, and has good application prospect as an effective and practical technical scheme.

The invention discloses a paper money sorting machine. The conventional paper money sorting and counting operations are basically completed through manual operation. The sorting machine comprises a paper money temporary storage mechanism, a paper money separation mechanism, a paper money extension and recognition mechanism, a paper money collection and arrangement mechanism, and a peripheral support. To-be-separated paper money is put in the paper money temporary storage mechanism, and enters the paper money extension and recognition mechanism piece by piece through the paper money separation mechanism. The paper money passes through nylon rollers with the constant rotating speed in upper and lower rows, and the face values of paper money are discriminated through employing the characteristics that the lengths of paper money with different face values are different and the shading time of paper money with different face values is different while passing through a bijection photoelectric sensor. In order to improve the discrimination accuracy of paper money, the sorting machine carries out the extension of the paper money in a mode of enabling the nylon rollers to rotate at different speeds. The paper money with different face values outputted by the paper money extension and recognition mechanism enters into a collection box corresponding to the paper money collection and arrangement mechanism. The sorting machine achieves the sorting and arrangement of the paper money with different face values.

The invention belongs to the technical field of geospatial information systems, and provides an immersive spatio-temporal data visual analysis multi-view layout method and system, aiming to solve the discontinuity and cognition between multiple views of the analyst existing in the prior art inefficiency etc. The method includes establishing a view layout space; calculating the attention degree of each view in the current stage of the visual analysis task; calculating the degree of association between the views in the current stage of the visual analysis task; Gaze change information of the position, or according to the analysis change information of a view about view data by the analyst, according to the degree of association between other views and this view and the degree of attention of other views, determine the corresponding view from other views and make it Linkage response. The method dynamically optimizes the multi-view layout, realizes the cognitive focus related to the visual analysis task, and maintains the continuity and efficiency of the analyst's cognition among multiple views.

The invention discloses a method for allocating a memory pool of an embedded operating system, comprising: step 1, according to the size and quantity of various memory blocks that may be used by the user and the size of the corresponding memory header, allocate a A memory pool formed by the memory blocks and memory headers; Step 2, initializing the memory pools to determine the starting addresses of memory blocks of various sizes; Step 3, for memory applications, if the memory application meets the minimum If there is waste exceeding the threshold in a single memory block, the memory application is satisfied by combining multiple memory blocks of different sizes; step 4, after the application of the memory application is completed, the memory block of the memory application is released. The present invention can greatly reduce and alleviate the problem of waste of memory resources in the management of the general memory pool, and at the same time, maintain the efficiency and reliability of the management of the general memory pool.
