Therefore it is the technical problem that those skilled in the art are badly in need of solving to provide a kind of simple switching on and shutting down operation.And mesh Before yet there are no the report of this aspect.
The content of the invention
It is an object of the invention to provide a kind of Auto Power On and shutdown, wireless interactive tutoring system terminal easy to operate Equipment wireless awakening and the method wirelessly closed, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme:
A kind of wireless interactive tutoring system terminal device wireless awakening and the method wirelessly closed, specific steps include:
1)The courseware that teacher selects to need is loaded into wireless interactive tutoring system and shown;
2)The operation of teacher courseware, which enters, starts answer state;
3)Wireless interactive tutoring system is by computer by answering information and answer state transfer to base station;
4)The answering information received and answer state are identified for base station, analyze and which kind of answer shape be currently at State:
(1)Start answer state:Base station is sent by base station radio module and wakes up code;
(2)Suspend answer state:Base station sends pause code by base station radio module;
(3)Stop answer state:Base station sends stop code by base station radio module or stops sending any type of volume Code;
5)Wireless interactive tutoring system terminal device initialization operation
(1) the aerial coding for whether thering is base station to send of wireless module detection of wireless interactive tutoring system terminal device;
A. wake-up code or pause code that base station is sent are detected, the initialization of wireless interactive tutoring system terminal device, enters it Holding state will be set by entering to open state, wireless module;
B. detect the stop code of base station transmission or be not received by coding, wireless interactive tutoring system terminal device enters to fall asleep Dormancy state;Now wireless module will be configured to electromagnetic wave wake-up states;When wireless module detects coding, wireless interactive teaching The MCU of system terminal equipment carries out discriminatory analysis to this coding, will be abandoned if not efficient coding, wireless interactive tutoring system Terminal device returns to sleep state;If coding, effectively and to wake up code, wireless interactive tutoring system terminal device will be opened Machine simultaneously enters answer state.
As the further scheme of the present invention:Coding transmitted by the base station radio module all passes through encryption.
Compared with prior art, the beneficial effects of the invention are as follows:It is whole that the present invention solves existing wireless interactive tutoring system End equipment wireless awakening and wireless the problem of closing and can not prevent that student is whole to wireless interactive tutoring system during attending class End equipment start is played, reduces the problem of wireless interactive tutoring system terminal device power consumption, is become certainly from manual startup and shutdown Dynamic startup and shutdown;Make wireless interactive tutoring system terminal device easy to operate, reduce terminal device maloperation, improve interactive Property.
Brief description of the drawings
Fig. 1 is that wireless interactive tutoring system sends coding flow chart;
Fig. 2 is that wireless interactive tutoring system terminal device receives coded treatment flow chart.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all Belong to the scope of protection of the invention.
Embodiment 1
In the embodiment of the present invention, a kind of wireless interactive tutoring system terminal device wireless awakening and the method wirelessly closed, Specific implementation process is as described below.
Referring to Fig. 1, transmitting terminal(Wake-up side):
1. the courseware that teacher selects to need is loaded into wireless interactive tutoring system and shown.
2. the operation of teacher courseware, which enters, starts answer state.
3. wireless interactive tutoring system is by computer by answering information and answer state transfer to base station.
4. the answering information received and answer state are identified for base station, analyze and which kind of answer shape be currently at State:
(1)Start answer state:Base station is sent by base station radio module and wakes up code.
(2)Suspend answer state:Base station sends pause code by base station radio module.
(3)Stop answer state:Base station sends stop code by base station radio module or stops sending any type of volume Code.
Wherein, the coding transmitted by base station radio module all passes through encryption, prevents other from wirelessly being done to wireless signal Disturb.
Referring to Fig. 2, wireless interactive tutoring system terminal device(Recipient):
