The teaching householder method that the present invention relates to a kind of teaching servicing unit of teaching auxiliary equipment, particularly a kind of radio communication and utilize this device.
[background technology]
Chinese invention patent 200610069294.9 discloses a kind of prompting device for teaching, through the caution switch at dais, to specifying the student on the classroom, to warn or puing question to.This device has following defective: (1) does not possess movability, and inconvenient operation when the teacher need warn the student, needs to operate to the dais.(2) equipment on teacher dais and the student's desk adopts wired connected mode, and wiring is installed complicated, and maintenance cost is high.(3) no CCC, function is limited: as not realizing all cautions, can not realize that the student marks, can not store and analysis etc. data.
[summary of the invention]
The purpose of this invention is to provide a kind of wireless teaching servicing unit simple in structure; Through wireless mode, carry out the auxiliary device of classroom instruction, through the flasher or the vibrating effect of appropriateness; The instruction type that expression receives is to be implemented in the silent call in the modern middle and primary schools classroom.
For realizing above purpose; The present invention provides following technical scheme: a kind of teaching servicing unit; Comprise the student with wireless transceiver, teacher with wireless transceiver, wireless repeater, USB radio switch and host computer; Wherein, the USB radio switch is connected through USB interface with host computer, and the student connects with the mode of employing radio communication between wireless transceiver, wireless repeater and the USB radio switch with wireless transceiver, teacher.
Said student is made up of single-chip microcomputer MSP430F2132 and wireless data sending chip CC1101 with wireless transceiver;
Said student disposes keyboard, light emitting diode and micro-vibration motor with wireless transceiver;
Said student is with wireless transceiver configuration power monitoring module.
The student transmits call instruction with wireless transceiver through wireless mode, representes the instruction type that receives with the mode of flasher or vibration.
It is 8.8 hertz that the student uses the flasher flicker frequency of wireless transceiver, and its Smalt passage of scintillation light is represented to put question to, and red passage of scintillation light representes to note, the vibrometer announcement of warning.
The student also comprises 5 yellow indicator lamps with wireless transceiver, representes 5 scoring items; When 1～No. 5 amber light glimmers separately successively, represent an ongoing scoring order, 6 buttons are represented 0～5 minute score value respectively.
Said teacher is made up of single-chip microcomputer MSP430F2132 and wireless data sending chip CC1101 with wireless transceiver;
Said teacher disposes keyboard, display screen and micro-vibration motor with wireless transceiver.The teacher uses wireless transceiver, transmits call instruction through wireless mode, points out the instruction type that receives with the mode of vibration, is shaped as the elongated strip of teacher's pointer.
Said wireless repeater is made up of single-chip microcomputer MSP430F2132 and wireless data sending chip CC1101, and the quantity of said wireless data sending chip CC1101 is two.
Said USB radio switch is made up of single-chip microcomputer MSP430F2132 and wireless data sending chip CC1101, and said USB radio switch configuration USB modular converter and radio receiving transmitting module are connected through the USB mouth with said host computer.
A kind of teaching householder method of utilizing said teaching servicing unit; The hand-held said teacher of teacher uses wireless transceiver; The teacher who on the dais same model is installed uses wireless transceiver, said student is installed on the student's desk uses wireless transceiver, and said wireless repeater is installed in sidewalls outside the classroom; Transmission range between child node and via node is no more than 15 meters, and via node is not less than 200 meters to the transmission range of total node.
Can divide into groups to use according to class to equipment, include 100 in the group and use wireless transceiver with interior student, 1 teacher use wireless transceiver, a wireless repeater, and each organizes employing different frequent points, and radio communication can the phase mutual interference between group.
When light was used with vibration simultaneously, the teacher woke up through colony and transfers to the destination to attention of student when giving lessons beginning.
The silent call design: the function of wireless calling device application layer is that light emitting diode, Vib., button are combined with wireless telecommunications.Application layer receives the order that data link layer is sent, and accomplishes the parsing to instruction, the instruction that receives is resolved to the combination of light emitting diode and Vib..The application layer of wireless calling device is also gathered key information, is transmitted to data link layer after the data check of key information is handled, and sends to corresponding wireless calling device module through Physical layer.
Anti-data collision design: via node is only transmitted score data; So reserved storage space on via node; Preserve the scoring of a class of this via node place group; Total node then reads to each via node poll, design like this, and then there is not data collision in via node between total node.The student retransmits in the time of collision with the data existence collision possibility of wireless transceiver to via node, adopts node serial number as retransmit interval, then can at utmost guarantee to retransmit successfully.
Low power dissipation design: employing can be through wireless low-cost RF module CC1101 that wakes up and low-power consumption MCU MSP430F2132, and the average stand-by operation electric current of entire equipment is below 5 μ A, and two batteries can be used more than 1 year.
The notice guiding: redness possesses warning function most, and simultaneously, the flasher ratio is easier to arouse attention.Simultaneously, note the scope of control light radiation, just can guarantee not influence other students' notice.
Beneficial effect of the present invention:
Employing wireless calling technology in conjunction with light and vibration, not only reaches the purpose of reminding the student to note effectively, and can not influence other absorbed students who listens to the teacher, and student's self-esteem is also well protected.Realization one class one is commented, and realizes the collection analysis to data through computer software, forms the scoring system.
We use red light and vibrate electrons device, wake attention of student to greatest extent up and turn to target, in minimum zone, do not have influence on the recent studies on exploitation of other students' notice simultaneously again.Purpose is in teacher's middle application of giving lessons, and improves student's notice, through long-term prompting, concentrates custom to such an extent as to form notice.Use red light direct projection objective body (but not direct projection eyes; With desktop 35 degree angles, generally below chin, control influences other Students'learning so to greatest extent); Non-scattering; Mainly wake notice up not the student of teacher destination, as absent-minded, do little trick, divert one's attention easily, hyperactivity, impulsion are wilful, the student of autocontrol force difference.The high vibrate electrons equipment of application controls sound wakes the student of doze up, and controlling to greatest extent again simultaneously influences other Students'learning.
Native system can also be realized the function of work attendance, can reflect the student attendance state faithfully.Simultaneously, also can need not artificially call the roll for making an appointment Teacher's Day.
