Abstract:

Aiming at the problem that the packet loss rate is too large due to the collision between the delay management instruction data and the borrowing information data generated by the existing delay constraint management system, a borrowing delay constraint management system for electronic library based on wireless communication is designed. In the hardware part, STM32 chip is used as the main control chip of wireless communication controller. The controller structure of wireless communication network is designed. Different reset modes are set by DC/DC converter, and a hardware constraint trigger circuit structure is constructed. The software part judges the status of borrowing delay, sets an information parameter to control the collision between data, and sets a constraint parameter inside the creed to realize the delay constraint management function. After selecting the equipment with known parameters and setting up the system test environment, the traditional constraint management system, the constraint management system in literature method and the constraint management system designed in this paper are used to carry out experiments. The experimental results show that the constraint management system designed in this paper has the minimum packet loss rate.
