Teaching device and method for lemon market experiment

Abstract

The invention discloses a teaching device and a teaching method for a lemon market experiment. The teaching device comprises an upper computer and N wireless response terminals, wherein N is an integer which is more than or equal to 3; the upper computer consists of a wireless transceiver and a computer; the wireless transceiver is used for receiving signals which are transmitted by the wireless response terminals and transmitting the received signals to the computer; the upper computer exchanges data with the wireless response terminals through the microwave of 433MHZ; the wireless transceiver consists of a first wireless transceiver module, a universal serial bus (USB) serial interface signal conversion chip and a first USB socket; the output end of the first wireless transceiver module is connected with the input end of the USB serial interface signal conversion chip; and the USB serial interface signal conversion chip is connected with the computer by the first USB socket. The terminals exchange the data with the upper computer more conveniently, the device and the method can adapt to a more and more complicated voting rule, a using range is extended, regional limit is reduced, and using sites are more flexible.

Description

technical field [0001] The invention relates to the technical field of voting equipment, in particular to a lemon market experiment device and method. Background technique [0002] The lemon market experiment is the teaching content that must be taught in microeconomics / western economics. There are currently three teaching methods: blackboard lectures, questionnaire surveys, and computer experiments. Blackboard lectures and questionnaire surveys are heavy and not intuitive enough. The restrictions are very large, and the construction of the computer room is very expensive. [0003] With the advancement of science and technology, electronic voting devices are used in more and more fields, playing an important role in various voting fields, and wireless response systems are widely used because they do not require wiring and are more flexible. Applications. Due to the different voting rules, the voting target scale is relatively large. The core processor speed of the traditio...

AI Technical Summary

Problems solved by technology

Due to the different voting rules, the voting target scale is relatively large. The core processor speed of the traditional wireless response terminal is too low and the function is limited, which has limited the wireless response system to play in more fields. In addition, the existing wireless response system The wireless response terminal can only exchange data with the computer through the wireless module, which is very inconvenient when the computer is not equipped with the corresponding wireless transceiver module

[0004] The traditional wireless response terminal is connected to the upper computer through the communication host. The communication host usually has a complicated structure and is inconvenient to move, which brings many restrictions to the use place of the wireless response system.

[0005] The traditional lemon market experiment is completed in a computer room composed of several computers. The environment for completing the experiment has great limitations, and the investment in building a computer room is larger
