A wireless sensor network architecture based on multifunctional and compound sensors comprises several sensing modules including a plurality of first sensor nodes and a second sensor node. The first sensor nodes are used for collecting a target signal after sensing that a moving target enters a detection area, extracting feature information of the moving target, analyzing the feature information of the moving target to form primary target information, and transmitting the primary target information to the second sensor node, The second sensor node performs moving target matching and association on the primary target information of the moving target that is transmitted by the plurality of first sensor nodes, collects the associated primary target information to form secondary target information. A control module used for synthesizing and calibrating the secondary target information, and obtaining by merging the calibrated secondary target information, the situation evaluation of the moving target to form advanced target information.

The present invention provides an inlet funnel () for cable terminal, which comprises a funnel body part () and a fixation part (). The funnel body part () has one end with a smaller opening and the other end with a larger opening, said funnel body () having a gradually increasing diameter (D) from said one end with the smaller opening to said other end with the larger opening, and the funnel body () is suitably to be installed over an electrical cable (C). The fixation part () is provided at said other end with the larger opening of said funnel body part () and adapted for the attachment of said inlet funnel (). The inlet funnel () further comprises a pretreated mounting part () extending from said one end side with the smaller opening towards said the other end side with the larger opening. Accordingly, the inlet funnel for cable terminal according to the present invention may reduce workload, save time, and simplify the mounting process.
