Description
Technical field
The utility model relates to electronic technology such as computing machine, radio control, multimedia overhead projector.It is specially adapted to modern education skill.
Technical background
The multimedia overhead projector teaching equipment is used for teaching, can allow the student clearly see image, the literal of lecture contents and hear that clearly the teacher explains the sound of content from display screen, thereby can improve the effect of giving lessons and listening to the teacher, so that improve the quality of teaching.
The multimedia overhead projector teaching equipment is used widely in Modern Education Technology, but existing this kind equipment, also be in a kind of fixed form, form the different relatively independent scattered form of equipment of multimedia various performances, and the form of function expansion poor-performing.This kind equipment has the following disadvantages in Modern Education Technology is used:
1, user (school) infusion of financial resources is big: projector installs need be fixed on the buildings ceiling, if multimedia equipment is all installed in every classroom, the capital quantity that the needs input is very big brings funds spendings big to school, causes school to be difficult to realize the multimedia form of giving a lesson.
2, extendability is poor: equipment needs to install separately network interface, public address system and various multimedia equipment interface.
3, use operation dumb: the teacher can only be movable in the narrow and small scope of control desk, is easy to generate the fatigue of giving lessons.If other purposes equipment in the convert multimedia equipment also needs special audio-visual education programme staff's cooperation.
4, install, debugging, maintenance be complicated: because of various multimedia equipments are discrete form, its connection line complexity needs that the professional installs, debugging, M R.
Summary of the invention
The purpose of this utility model is in order to overcome the above prior art weak point in using, the spy provide have controlled in wireless, projector distance and adjustable height, scalability are good, can central controlled multimedia overhead projector teaching equipment---mobile integrated multimedia teaching platform (to call this equipment in the following text).
The utility model is to realize above-mentioned purpose by new structural design.This equipment mainly is made of projector, middle control main frame, computing machine, audio amplifier, public address system, rack, Wireless Keyboard and mouse group.In rack 5, on the chute fixed mount of drawer type, from top to bottom be mounted with projector 1, middle control main frame 2, main frame 3, audio amplifier main frame 4 (seeing accompanying drawing 1) respectively, be mounted with remote controller and wireless receiver box 6 (seeing accompanying drawing 3) at the top of cabinet.Each system equipment forms an integral body by the connection of the interface circuit on the relevant wiring board; Or interior each system equipment of rack can be selected arbitrarily, the mutual alignment conversion forms an integral body.Handrail 7, signal input and output web joint 8, fan 9, power supply, network interface web joint 10 (seeing accompanying drawing 2) are installed at the back side of rack.Have louvre 13 in the side of rack, the hole 14 that amplifies, the side door of rack and top cover all are equipped with the metal latch 12 (seeing accompanying drawing 3, accompanying drawing 4) of locking.For the ease of moving, the rack bottom is mounted with 4 universal wheels 20.In rack, except the groove of being convenient to settle each system equipment, support,, on projector's carriage 15, be provided with projector's height adjustment knob 16 (seeing accompanying drawing 5) for height, the distance that can adjust projector.
The equipment that the utility model provides, complete machine is modular design, is an integral device, compares with existing multimedia equipment, has the following advantages:
1, user's reduced investment, the service efficiency height.Teaching building can only be joined this equipment of cover for every layer, can use for classroom between many.Therefore, can reduce school and purchase the machine cost, improve the equipment service efficiency, satisfy the teaching needs of Modern Education Technology.
2, this equipment can conveniently move, and can independently finish the mutual switching and the broadcast of vision signal, pcs signal, sound signal.
3, wireless speech input.Speaker's wireless speech in 20 meters accessible scopes can be broadcasted speaker's sound clearly.
4, these functions of the equipments are more, can import and broadcast various audio frequency and video and Computer signal, can insert multiple audio frequency and video and computer equipment, and can switch mutually between each equipment, also can store a large amount of coursewares and file.
5, use is easy to operate.This equipment by professional and technical personnel's assembly and adjustment good after, user of service (teacher) only need pack my needed data in the computing machine, press remote controller button or wireless mouse again, just can demonstrate image, literal, broadcast the sound of explanation from the audio amplifier public address system from projector's display screen.The scope of operator's action is between 2-10 rice.The interface operation of this equipment is simple, and interfaces for external devices is obvious, and the teacher is as long as the different interface of conversion just can obtain corresponding instructional function.
6, it is convenient to safeguard, overhaul.The maintenance of projector and computing machine need not to pull down, as long as drawer is pulled out and can be carried out.
