Abstract

The invention discloses a 4G network based school dining hall dinning system, comprising a server, a video acquisition module, a ticketing device, a 4G network transceiving module and a 4G user terminal. The video acquisition module, the ticketing device and the 4G network transceiving module are all connected with the server. The 4G network transceiving module is connected with the 4G user terminal through a mobile 4G network. The video acquisition module comprises a BL-3298D model camera for collecting a video signal, a preprocessing module for performing Y / C separation, synchronization separation, level clamping and amplitude amplification on the collected video signal, and a TMS320F2812 chip for performing A / D conversion on the preprocessed signal. The BL-3298D model camera sends the collected video signal to the preprocessing module to be processed and then sends the processed video signal to the TMS320F2812 chip for A / D conversion, and the converted signal is connected with the server.

Description

technical field [0001] The invention belongs to the field of dining systems, and in particular relates to a school dining system based on a 4G network. Background technique [0002] Due to the increasing popularity of informatization and intelligent construction in all walks of life today, the whole society has higher and higher requirements for the efficiency of various industries, especially the service industry, which must not only meet the service needs of the served people, but also Improve service quality and improve service efficiency. [0003] Now many places are overcrowded and need to wait in line, such as going to the bank to do business, need to line up to go to the mobile business hall, need to line up to go to the hospital, need to line up to go to the vehicle management office, need to line up to go to the housing management bureau, and even have to queue up to eat . People spend a lot of time queuing, and it often happens that it only takes a minute or two ...
