The application discloses a mesh wireless network device conflict detection processing method and system for an intelligent driving test scene. Before entering the test, active detection is performed on devices in an active state in the mesh wireless network, a mapping relationship between device IP and MAC is constructed, device conflicts of repeated IP, unregistered MAC or out-of-bound network segments are identified, a first detection result is obtained; during the test, address resolution protocol ARP packets in the mesh wireless network are passively monitored, device conflicts occurring during the test are detected, a second detection result is obtained; a multi-dimensional conflict feature vector is constructed based on the first detection result and / or the second detection result, a conflict level is determined by using a conflict determination model based on a gradient boosting decision tree GBDT, and a conflict risk classification result is output; and control instructions bound with the test process are executed according to the conflict risk classification result. The application completely solves the problem of network paralysis caused by unapproved new device access.

The invention provides a letter sorting machine control system based on EtherCAT double-link redundancy. The letter sorting machine control system comprises a main controller, a redundancy switching unit, a distributed slave station and branch control module, a belt transmission module and a grid display module. The main controller adopts multi-core CPU function isolation, binds different tasks to corresponding cores and allocates execution cycles; the redundancy switching unit constructs a double-link annular redundancy network, automatic switching is achieved when links are abnormal, and communication stability is guaranteed; the distributed slave stations are provided with terminal modules according to needs, are integrated in slave station boxes and are flexibly connected to execution components of all functional areas. And the lattice display module adopts a group leader-group member structure, so that the load of a main network is reduced. The system sets priorities for EtherCAT network groups based on signal real-time performance, realizes IO signal rapid response, and supports flexible expansion of slave station boxes. The reliability, the real-time performance and the expansibility of letter sorting control are improved, the method is suitable for a high-speed sorting scene, and the efficient operation requirement of the postal logistics industry is met.
