Abstract: A network device role self-adaptive method and apparatus are provided. Specifically, a first network device and a neighbor network device both determine their respective priority according to information including a connection result between the corresponding network device itself and a server; the first network device receives a second start frame which is sent by the neighbor network device and comprises the priority of the neighbor network device, and then determines whether its own priority and the priority of the neighbor network device meet preset conditions; and if yes, when the priority of the first network device is higher than the priority of the neighbor network device, the first network device determines its own role as an authentication access controller, and when the priority of the first network device is lower than the priority of the neighbor network device, the first network device determines its own role as a request device.

Abstract: Disclosed is a parcel sorting system, it includes a main frame and a sorting tower; the main frame includes a vertically arranged spiral slide and a supporting plate horizontally arranged outside the spiral slide, and the lower end of the spiral slide is provided with a collection bag main outlet. The supporting plate is provided with a collection bag falling port facing the spiral slide; the sorting tower includes a receiving transfer device, a plurality of bagging output devices disposed below the receiving transfer device, and a tower housing disposed below the bagging output device; A plurality of sorting towers are arranged on the supporting plate around the spiral slides, and the collection bag discharge ports of each sorting tower are respectively connected to the falling ports of the collection bags of the supporting plates. The invention which greatly improves sorting efficiency compared to single-pass sorting of existing sorting systems.
