Classroom teaching generally applies blank or multimedia touch-control all-in-one machine carries out multimedia interactive teaching, and teacher is by directly completing the demonstration of multimedia teaching resource in corresponding on-screen options.Teacher can only demonstrate, and can not draw, write at the enterprising rower of corresponding resource, inconsistent with traditional study habit, emphasis is not given prominence to; And teacher is " fixed " before screen in teaching process, Real Time Observation, mutual cannot be carried out in student; Existing two kind equipments use Internet resources inconvenient, can only use local teaching resource, do not meet teaching demand under " internet+" environment; Present chalk writing mode, chalk dust pollutes has injury to teachers and students; Existing blank and multimedia touching all-in-one cost high, and maintenance and repair is difficult, and the application cycle is shorter.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can substitute chalk writing, make interactive teaching form more diversified and the radio multimedium interactive teaching terminal that cost is low.
Radio multimedium interactive teaching terminal described in the utility model, comprise radio receiving terminal box and telepilot, radio receiving terminal box is arranged remote control change-over switch, audio output port, power input port and the VGA output port, HDMI output port, the output port of power source that connect corresponding to projector, WIFI wireless transport module, signal conversion module, power transfer module and remote control module are set in radio receiving terminal box; WIFI wireless transport module receives the signal of portable mobile terminal equipment, supports 802.11b/g/n agreement; WIFI radio multimedium signal is synchronously converted to HDMI signal, VGA signal and sound signal by signal conversion module, and HDMI signal, VGA signal, sound signal export respectively by HDMI output port, VGA output port, audio output port; Remote control module controls the keying of projector and radio receiving terminal box; 220V alternating current is converted to 5V direct current by power transfer module, for WIFI wireless transport module, signal conversion module, remote control module are powered.
Wherein: WIFI wireless transport module can be separated with radio receiving terminal box, upgrading is convenient to; Remote control module can adopt infrared remote control module or wireless remote control module or other can realize the module of distant control function; In order to the duty enabling operator observe radio receiving terminal box and remote control module intuitively, radio receiving terminal box arranges relay indicating light and remote-control indicating lamp.
This radio multimedium interactive teaching terminal is specialized in classroom projector and is used, directly this terminal can be connected on classroom projector, by WIFI wireless transport module by the content synchronization on teacher's portable mobile terminal equipment (as mobile phone, panel computer etc. support the equipment of 802.11b/g/n agreement) on projection screen, teacher operates the teaching resource using local multimedia teaching resource and interconnected instant online to search by portable mobile terminal device screen.Open remote control change-over switch during use, thus directly can control the action of projector and radio receiving terminal box with telepilot.
Replacing original wire signal to connect by this terminal (also can parallel join, automatic selection), the wireless transmission of teaching multimedia signal can be realized, on the one hand, the mobility of teacher can be ensured, be convenient to teacher and go deep into student's medial side and say that observation limit, limit is instructed; On the other hand, teacher can directly carry out writing, marking and draw on the screen of portable mobile terminal equipment, and can replace chalk writing completely, pollution abatement endangers; In addition, by the screen operator of portable mobile terminal equipment, teaching resource can be amplified arbitrarily, reduce, be convenient to teaching.
The beneficial effect that the utility model is compared with prior art had is:
1, school's investment burden is alleviated: this product only has the price of 1/to ten/3rd of conventional white board or multimedia touching all-in-one;
2, the optimizing application traditional classroom instruction efficiency of new technology, really achieves in " internet+classroom ", integrates various teaching resource and be applied to classroom;
3, add teachers ' classroom teaching form, teacher teaches class hour, directly enters in the middle of student and does not delay writing on the blackboard and multimedia application control;
4, teacher can need the content uploading shown to project in classroom at any time, carries out interactive teaching;
5, chalk-writing is thoroughly solved on the impact of teacher, student's health.
