Self-positioning method for network node of wireless sensor

The invention relates to a self-positioning method for a network node of a wireless sensor. The self-positioning method comprises the following steps of flooding broadcast to internet by utilizing a distance vector exchange protocol so that all nodes obtain the light-flooding number of all anchor nodes; clustering the anchor nodes to form a plurality of subareas; judging a current sub-network topology structure by utilizing a network topology structure judgment factor according to light-flooding distance information among the anchor nodes; screening elements in a set one by one to find out nodes meeting promotion conditions and reference anchor nodes for positioning the nodes; promoting the nodes meeting the judging conditions; and repeatedly traversing all the nodes and carrying out a promotion strategy till all unknown nodes are positioned. Compared with the prior art, the self-positioning method for the network node of the wireless sensor, disclosed by the invention, has the advantages of adding the node promotion strategy based on a DV-distance algorithm, reducing the distance accumulation errors of route vectors among the nodes of an asymmetrical network and improving the integral positioning precision.

Product molding method based on FDM technology

The invention belongs to the technical field of 3D printing, and discloses a product molding method based on a FDM technology. The product molding method comprises: (1) printing the circumferential contour of the first layer pattern of a bottom surface according to the input two-dimensional pattern data of the bottom surface; (2) printing an internal structure in a reciprocating movement manner byusing the previous printing ending point as a starting point for printing the bottom surface internal structure; (3) after printing the first layer pattern, moving a printing head to the circumferential contour of the next layer pattern according to the coordinates set by the two-dimensional pattern data, and returning to the step (1) until the patterns on all layers of the bottom surface are completed; (4) moving the printing head to the circumferential contour of the pattern on the bottom surface; (5) printing a side wall by the printing head according to a designed spiral lifting path until the side wall is printed; and (6) if the product has a top surface, returning to the step (1), and printing the top surface by using the same method as the bottom surface printing, otherwise, endingthe printing. According to the present invention, the printing efficiency of the method is high.

Broadcast Scheduling Method for Multi-channel Big Data Items Based on Two-layer Scheduling Strategy

The invention discloses a multi-channel large data item broadcast scheduling method based on a double-layer scheduling strategy. The method includes three processes including large data item subpackaging, high-level data item channel allocating and low-level single channel data item allocating. In the initial stage, a server side judges whether large data items are included according to channel capacity of available channels and the data length of all required data items. If the large data items are included, a pre-subpackaging mechanism needs to be carried out and subpackaging is reasonably carried out. A high-level data item channel allocating algorithm is adopted, and the algorithm guarantees optimal channel allocation; meanwhile, the algorithm is optimized, and accordingly the situation that the channels skip many times when mobile subscribers obtain multiple data items is avoided, and average access time is reduced. In actual application, a feedback mechanism can be introduced for a low-layer single channel data item scheduling strategy, when the subscribers of mobile terminals receive data, the server side is fed back, if certain data are not required, the data can be removed in the next pushing cycle, and the average access time is greatly reduced.

Display method, processing method and related device in eigenvalue transfer

The embodiment of the invention discloses a display method, a processing method and a related device in eigenvalue transfer. When the user triggers the corresponding feature value transfer control based on the acquisition intention for the target product, the target product is acquired; according to a characteristic value transfer request generated in response to the trigger, calling a feature value product item corresponding to the target product; the first size information is determined based on the number of the feature value product items, and the determined first size information is matched with the number of the feature value product items of the target product, so that the display size of the transfer function page with the first size information conforms to the number of the feature value product items needing to be displayed, and the size is more reasonable. And the feature value product item is used for identifying the feature value value provided by the target product, so that the user can directly transfer the feature value according to the feature value product item displayed by the transfer function page. Before actual transfer, only one page is skipped, that is, thefunction page is transferred, so that the skipping frequency is reduced.
