The invention discloses a method for adjusting the long life of a multicast tree based on a DFM strategy. In the method, firstly, the shared nodes are sorted according to the number of occupied multicast trees, and then the sorted shared nodes are sorted from participating multicast trees one by one. Separation; in the process of separating the shared nodes, select the participating multicast tree according to the number of child nodes, find a backup parent node for the child nodes of the shared node in the selected multicast tree, and then execute DFM by sending and receiving messages Strategy. The method of the present invention solves the problem of using the DFM strategy to separate the shared nodes when there may still be some shared nodes after the establishment of multiple multicast trees, so that as many shared nodes as possible can be transformed into ordinary multicast nodes only in one multicast tree. The nodes in the tree prolong the working time of the wireless sensor network, maintain long-lived multicast data transmission, and balance the energy consumption among nodes.

FSAC racing car active braking system based on manned and unmanned driving modes
ActiveCN113071458ACompact structureMeet strategic needsBraking action transmissionSwitching frequencyLoop design
The invention provides an FSAC racing car active braking system based on manned and unmanned driving modes. The FSAC racing car active braking system comprises a first active braking cylinder, a second active braking cylinder, a linear motor, a first passive braking cylinder, a second passive braking cylinder, a first two-position three-way electromagnetic valve, a second two-position three-way electromagnetic valve and an unmanned driving control system. Compared with an existing scheme of a servo motor and a mechanical transmission mechanism, the control circuit is adopted to accurately control the linear motor to move, and then the service braking function of an unmanned driving mode is achieved. The manned driving mode and the unmanned driving mode are independent from each other through switching of different driving modes, and the active mode and the passive mode are both of a double-loop design, so that safety is guaranteed. The innovation lies in that an MOSFET is applied, the size is dozens of times smaller than that of a relay, the switching frequency is high, the response speed is high, noise is avoided, energy consumption is low, physical contacts are avoided, and electromagnetic interference is avoided, so that the problems of limited space and light weight of an automobile are solved.
