Abstract
The utility model provides a radio-frequency multichannel answering racer, which comprises an answering racing portion and a main control portion. The answering racing portion includes a key, a radio-frequency module A and a power supply A, wherein the key and the power supply A are respectively connected with the radio-frequency module A. The main control portion includes a radio-frequency module B, a setting module, a display module, a voice module and a power supply B, wherein the setting module, the display module, the voice module and the power supply B are respectively connected with the radio-frequency module B. The radio-frequency multichannel answering racer has the advantages of realizing information transmission and wireless transmission between the answering racing portion and the main control portion by the aid of a high-integration radio-frequency wireless chip, overcoming the shortcomings of connection through wired cables, and realizing long transmission distance, low cost and power consumption, high interference resistance, high integration, simple development and fine expandability.
Description
Technical field
The utility model relates to a kind of radio frequency multichannel question-and-answer game apparatus, specifically, relates to a kind of multichannel question-and-answer game apparatus with integrated-type radio frequency chip transmission data.
Background technology
Question-and-answer game apparatus is a kind of to be in contest, race to be the first to answer a question in the activity, can judge the person's of racing to be the first to answer a question machine accurate, just, intuitively.The circuit that present employed question-and-answer game apparatus has complexity is not easy to make, and reliability is low, implements difficulty; What have then uses some special-purpose integrated packages, and that special-purpose integrated package is bought is very difficult.Generally all be to connect between host's control circuit and the player's control circuit, to reach the purpose of communication each other with cable.There is the problem of cable connection reliability in this method when reality is used, wire signal transmission mode signal is decayed easily and is subjected to electromagnetic interference (EMI), and installs and take care of also inconvenient.The use wireless transmission is transmitted the signal between each question-and-answer game apparatus circuit, then can effectively avoid the drawback of wire transmission signal.
Summary of the invention
The purpose of this utility model will overcome the deficiencies in the prior art part exactly, the multichannel question-and-answer game apparatus that provides a kind of integrated-type radio frequency chip to realize.
Radio frequency multichannel question-and-answer game apparatus of the present utility model, comprise and race to be the first to answer a question part and main control part, the said part of racing to be the first to answer a question comprises button, radio-frequency module A and power supply A, wherein button, power supply A are connected with radio-frequency module A respectively, said main control part comprises radio-frequency module B, setting module, display module, voice module and power supply B, and wherein setting module, display module, voice module, power supply B link to each other with radio-frequency module B respectively.Radio communication between radio-frequency module A and the B.
Preferably,
The said part of racing to be the first to answer a question has a plurality of.
Said radio-frequency module A and B adopt the integrated RF chip of the SoC nRF9E5 of Nordic VLSI company to realize.Its built-in 433/868/915MHz transceiver, 8051 compatible MCU have very high integrated level.Radio-frequency module A and B all adopt the nRF9E5 chip.Can allow each main system can connect many group peripherals for the user provides 127 independently channels in theory.Response, wireless data that radio-frequency module A realizes racing to be the first to answer a question signal send and control function.Radio-frequency module B realize received RF modules A data, regularly, show time score, select hand horn, warning and control function.
Setting module has adopted free-standing keyboard, and its button is fewer, and the work of each button is not disturbed mutually in the keyboard.
Display module is made up of 3 common cathode charactrons and latch 74HC573.Select hand horn and timing shared microcontroller eight bit data mouth.Countdown was automatically selected hand horn to race to be the first to answer a question the back the player and was just shown always and race to be the first to answer a question beginning ability refresh data up to next time after the host sets and press initiating key time.
In the voice module, the auditory tone cues part mainly is a Single-chip Controlling hummer sounding, in order to distinguish foul, to answer mistake and overtime, the length at control hummer sounding interval and the length of sounding.
Power supply adopts direct supply, is the radio-frequency module power supply.
The utlity model has following technique effect: the utility model is realized racing to be the first to answer a question partly and the information transmission between the main control part with highly integrated wireless radiofrequency chip, and wireless transmission has overcome the shortcoming that wire cable connects; Long transmission distance, cost is low in energy consumption, antijamming capability is strong, integrated level is high, exploitation is simple, extensibility is good.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
As shown in Figure 1, radio frequency multichannel question-and-answer game apparatus of the present utility model, comprise and race to be the first to answer a question part and main control part, the said part of racing to be the first to answer a question comprises button, radio-frequency module A and power supply A, wherein button, power supply A are connected with radio-frequency module A respectively, said main control part comprises radio-frequency module B, setting module, display module, voice module and power supply B, and wherein setting module, display module, voice module, power supply B link to each other with radio-frequency module B respectively.Radio communication between radio-frequency module A and the B.Racing to be the first to answer a question part can have a plurality of.Said radio-frequency module A and B adopt the nRF9E5 chip.
Racing to be the first to answer a question part, when a key is pressed, just producing one the tunnel and race to be the first to answer a question signal.This signal is sent to radio-frequency module A radiating portion by MCU integrated among the radio-frequency module A, and the data that receive are packed according to the CRC agreement sends to wireless radiofrequency module B.At receiving end, radiofrequency signal is partly imported by receiving antenna, uses the SPI interface to be sent to integrated microcontroller among the wireless radiofrequency module B via the transceiver decoding processing among the wireless radiofrequency module B, shows these data and warning by MCU integrated among the radio-frequency module B.
It is as follows to race to be the first to answer a question process: the host operates main control part, and part is raced to be the first to answer a question in player's operation.The host can revise the time that the time of racing to be the first to answer a question and player answer a question by each operating key and be provided with.After host's button began, the new time began effectively, and the player begins to race to be the first to answer a question into effectively, and the charactron demonstration is raced to be the first to answer a question the time countdown and selected hand horn, points out at last five seconds loudspeakers of countdown.The player does not just race to be the first to answer a question and is considered as foul if the host presses the beginning button, and charactron shows the foul code name, and loudspeaker continues to take place.The host can finish by button, and a new round is raced to be the first to answer a question beginning.
The above only is a preferable embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
