Wireless intelligent answering system supporting multi-network and multi-terminal and data transmission method thereof

Abstract

The invention discloses a wireless intelligent answering system supporting multiple networks and multiple terminals and a data transmission method thereof. The wireless intelligent answering system comprises at least one central node and a plurality of terminal nodes, wherein the central node is configured to a teacher in each examination room, the terminal nodes are configured to answering students, and each terminal node is communicated with a central node Zigbee communication module, a central node Bluetooth module and / or a central node infrared ray transceiver of the central node corresponding to the examination room where the students are through a terminal node Zigbee communication module, a terminal node Bluetooth module and / or a terminal infrared transceiver of the terminal node. Compared with the traditional examination mode, according to the wireless intelligent answering system, the time of the teacher gathering and correcting answer sheets is omitted, examination scores of the students can be obtained immediately after the examination finishes, the examination situation of an entire class can be analyzed timely, and the education quality is improved.

Description

technical field [0001] The invention relates to a wireless perception network, in particular to a wireless intelligent question answering system supporting multiple networks and multiple terminals and a data transmission method thereof. [0002] Background technique [0003] With the maturity of wireless network technology, multi-network integration and collaboration has become a hot spot in recent years. Mechanistically speaking, multi-network integration is to change the original multiple vertical subsystems into horizontal systems, and locally connect each subsystem to the network through various interface forms. How to integrate multiple wireless network transmission protocols into the network without barriers, and multiple terminal devices work together is the core of multi-network and multi-terminal technology. [0004] The existing intelligent answering system usually adopts a single data transmission method, which makes the transmission efficiency low. In the case...

Problems solved by technology

[0006] The purpose of the present invention is to aim at the existing intelligent question answering system usually adopting a single data transmission mode, which makes the transmission efficiency low, and in the case of large data volume and multiple nodes, the effect is not ideal; the transmission distance is low, and in the environment with obstacles In this situation, the transmission efficiency will be greatly reduced, and the packet loss rate will also increase accordingly. A wireless intelligent question answering system supporting multi-network and multi-terminal and its data transmission method are proposed.
