Abstract

The invention relates to a wireless personal digital assistant (PDA) and database-based experiment evaluation system. The system comprises a background server, a wireless router, a card swiping subsystem and a client consisting of a local area network (LAN) PC, a plurality of campus network (CN) PCs and a wireless PDA, wherein the background server, the LAN PC, a card swiping PC and the wireless router are connected to the experiment centre LAN; an IC card reader is connected to the card swiping PC through a USB interface; the CN PCs are connected with the CN; and the experiment centre LAN is connected with the CN. A wireless PDA and database-based experiment evaluation method comprises the following steps of: swiping cards by students, logging on to a WWW server, querying student information, selecting a student and an experiment project, querying evaluation standard information, estimating experiment and the like. With an evaluation standard, the system and the method have the advantages of strictness and consistency, more comprehensive evaluation indexes, convenient arrangement of experiment results and the like, and create conditions for the complete opening of the laboratory.

Description

technical field

[0001] The invention belongs to the technical field of wireless local area network and palm computer, in particular to an experiment evaluation method based on wireless palm computer and database. Background technique

[0002] Wireless Local Area Network (WLAN for short) is an easy-to-use data transmission system, which includes technologies such as Bluetooth, IEEE802.11 series, HiperLAN, and HomeRF. Among them, the technology widely used at present is IEEE 802.11 series. Wireless local area network can make use of the simple access structure to allow users to achieve the ideal state of "portable information and convenient access to the world". Wireless LAN is generally not used to replace wired LAN, but to make up for the shortage of wired LAN to extend the network. Wireless local area network has very obvious advantages in solving the problem of moving information points, improving teaching efficiency and saving the cost of network integrated wiring. It i...
