Embodiment 1

[0084] The invention discloses an interactive examination evaluation system, which can be used in various fields, such as teaching, voting, academic reports and the like. Hereinafter, the present invention will be introduced by taking the present invention as an example for teaching system.

[0085] see figure 1 , the interactive examination evaluation system includes at least one hand-held teacher terminal 10, several hand-held student terminals 20, a host computer 30, and a base station 40.

[0086] Wherein, the base station 40 is a wireless receiving base station based on the ZigBee / 802.15.4 protocol; the handheld teacher terminal 10 includes a wireless communication module based on the ZigBee / 802.15.4 protocol; the handheld student terminal 20 includes a wireless module based on the ZigBee / 802.15.4 protocol; Communication module: the upper computer 30 is connected with the wireless receiving base station 40, obtains the data sent to the wireless receiving base station 40 ...

Embodiment 2

[0135] In this embodiment, a real-time feedback system, the real-time feedback system includes:

[0136] - Wireless receiving base station based on ZigBee / 802.15.4 protocol;

[0137] - At least one handheld host terminal, including a wireless communication module based on the ZigBee / 802.15.4 protocol;

[0138] - Several handheld feedback terminals, including wireless communication modules based on ZigBee / 802.15.4 protocol;

[0139] - The upper computer is connected with the wireless receiving base station, and obtains the data sent to the wireless receiving base station by the handheld hosting terminal and the handheld feedback terminal.

[0140] The difference from Embodiment 1 is that in this embodiment, the present invention can be used in other fields besides the teaching field. For example, the present invention is used in voting and election processes; of course, it can also be used in other fields requiring feedback.

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...
