Abstract

The invention discloses an interactive exam estimation system and a method, solving the problem of collision, interference and data loss generated during one receiving and multiple sending of the traditional wireless interactive feedback system adopting frequency hopping or time sharing technology. The invention adopts a unique double-window mode, the interactive teaching tool is automatically embedded into PowerPoint, teachers do not need to modify content of the daily prepared lessons to realize interactive teaching, thus solving the limitation caused by the fact that teachers can only use the feedback system which takes the PowerPoint special template as the main body; one-to-multiple real-time full bidirectional communication is realized between teachers and students and standardized test paper sending exams can be performed.

Description

technical field

[0001] The invention belongs to the technical field of high-end wireless network communication, and relates to an interactive examination evaluation system, in particular to an interactive examination evaluation system based on a Zigbee wireless network; meanwhile, the present invention also relates to an evaluation method of the above-mentioned interactive examination evaluation system. Background technique

[0002] Zigbee is synonymous with IEEE 802.15.4 protocol. The technology specified under this agreement is a short-distance, low-power wireless communication technology. This name comes from the eight-character dance of bees, because bees (bees) use the "dance" of flying and "buzzing" (zig) to shake their wings to communicate with their companions the location information of pollen, that is to say, bees rely on this way Form a communication network in the group. It is characterized by short range, low complexity, low power consumption, low data rate, a...
