A kind of umbrella rib structure that can enhance wind resistance, including long slot, short slot and middle rib, long slot and middle rib are hinged by first middle rib joint, one end of short slot and the middle part of long slot are hinged by first grommet, the end of short slot close to the middle part of long slot is equipped with second grommet, second grommet is connected with umbrella closing spring and one end of short pull wire;First middle rib joint includes third grommet and fourth grommet, third grommet is hinged with the inside of the end of long slot, fourth grommet is hinged with the other end of short pull wire;The other end of umbrella closing spring is connected with the fifth grommet between first grommet and third grommet, the head end of first middle rib joint is equipped with clamping slot, the connecting hole of third grommet and first middle rib joint is long hole, sixth grommet is equipped between third grommet and fifth grommet on long slot, sixth grommet is set to when umbrella rib is fully opened, clamping slot is just clamped on sixth grommet.This structure has the advantages that when wind force is small, umbrella surface will not be blown over, when wind force is large, umbrella rib will not be broken.

The application discloses a food traceability system based on a chain ring type modular traceability architecture, comprising: an entry node module for collecting and storing cargo entry data in a park database; a transfer module for recording state monitoring data of cargo in the process of circulation in a fresh food industry park and storing the data in a transfer database; an exit node module for recording cargo exit data and storing the data in an exit database; a voucher generation module for identifying in-park data of cargo circulation in the park through a traceability voucher ID, and encrypting the traceability voucher ID to generate a delivery order two-dimensional code when the cargo exits the park; and the voucher generation module establishes a mapping table of in-park data and external data. The application also discloses a traceability method of the food traceability system. Compared with the prior art, the application solves the problems of single point failure leading to traceability chain breakage and cross-subject data cooperation difficulty in the existing food traceability system.
