Description
Technical field
The utility model relates to a kind of multi-media classroom management system, is exactly specifically a kind of multi-media classroom fault wireless calling system.
Background technology
At present, along with the development of educational undertaking, the multi-media classroom of universities, middle and primary schools is more and more.The equipment of multi-media classroom also becomes increasingly complex, and fault is also more and more frequent.In teaching, the event of burst Multimedia Classrooms fault effects teaching happens occasionally.While breaking down, the teacher often is difficult to again find quickly and easily the maintainer, thus the severe jamming teaching.
Summary of the invention
The purpose of this utility model is to provide a kind of Multimedia Classrooms fault wireless calling system.By wireless calling system, not only facilitated faculty's short calling maintainer, and be conducive to the maintainer is managed.Due to wireless, also be conducive to existing multi-media classroom is renovated simultaneously.
This multi-media classroom fault calling system comprises many cover wireless calling devices and radio receiver.Wireless calling device comprises radio-frequency unit, control section, display lamp, call button, and control section is connected with radio-frequency unit, display lamp and call button respectively.Radio receiver comprises information process unit, radio-frequency unit, display screen, loudspeaker.Information process unit is connected with display screen with loudspeaker respectively, and wireless calling device and wireless reception device are by wireless connections.
The beneficial effects of the utility model are: when the faculty encounters equipment failure, press call button calling maintainer and keep in repair.The maintainer is after duty room receives call signal, the multi-media classroom broken down is confirmed in information and the voice suggestion of the display screen by checking receiving trap, press answer button simultaneously, now the display lamp of the multi-media classroom of generation fault can turn green, inform the faculty, the maintainer has received signalling trouble.After the maintainer arrives multi-media classroom, again press call button and eliminate alarm.Managerial personnel confirm maintainer's working condition by the record of checking receiving trap.Thereby improved the processing speed of Multimedia Classrooms fault, also strengthened the management to the maintainer.
The accompanying drawing explanation
The structural representation that accompanying drawing is the utility model embodiment.
In Fig. 1,1, control section, 2, call out radio-frequency unit, 3, display lamp, 4, call button, 5, display screen, 6, the received RF device, 7, information process unit, 8, loudspeaker.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the Multimedia Classrooms fault wireless calling system that the utility model provides is comprised of with the radio receiver that is arranged on the maintenance center the wireless calling device be arranged in multi-media classroom.Wireless calling device is comprised of control section (1), calling radio-frequency unit (2), display lamp (3), call button (4), and radio receiver is comprised of display screen (5), received RF device (6), information process unit (7), loudspeaker (8).Call out radio-frequency unit (2) and be connected with control section (1) respectively with display lamp (3), display screen 5, received RF device (6) and loudspeaker (8) are connected with information process unit (7) respectively.Wireless calling device is connected by radio signal with radio receiver.
Wireless calling control section (1) main body is comprised of single-chip microcomputer, and main function is the work of coordinating to call out radio-frequency unit (2), display lamp (3), call button (4).Control section (1) is controlled and is sent digital signal, receives and resolves the digital signal of receiving.Radio-frequency unit (2) and received RF device (6) are mainly the sending and receiving wireless signals, and optional frequency selects 315MHz or 433MHz. display lamp (3) has three kinds of states of red, yellow, and green.Information process unit 7 can be comprised of common PC, also can be comprised of embedded system.Information process unit (7) major function is to coordinate the work of display screen (5), received RF device (6), loudspeaker (8).Information process unit (7) needs to control displaying contents, transmission and the parsing wireless signal of display screen (5), the pronunciation of control loudspeaker (8), needs to record all-calls simultaneously and replys record so that manage.
Its course of work is as follows: when the faculty runs into the Multimedia Classrooms fault, can press call button (4), now call out display lamp (3) and send ruddiness.After control section (1) is sensed call button (4) and pressed, by calling out radio-frequency unit (2), send the digital signal that comprises this classroom address code.Received RF device (5) is passed to information process unit (7) after receiving wireless digital signal, information process unit (7) is by resolving its digital address, judgement is that equipment failure appears in which multi-media classroom, failure message is shown and passes through loudspeaker (8) and play voice signal at display screen (5) simultaneously.After the maintainer receives alarm signal, control information processing unit (7) sends the wireless digital answer signal that comprises address information by received RF device (6).After receiving wireless digital signal, the calling radio-frequency unit (2) that is arranged on multi-media classroom sends signal to control section (1), control section (1) is resolved the address information of this wireless digital answer signal, if be the address information in non-classroom, this signal ignored.If the address information in this classroom makes display lamp (3) flavescence.Now mean, the maintainer has received call request, the maintenance of can coming at once.After the maintainer reaches the spot, press call button (4).Now control section (1) can become green by the lamp of display lamp (3), as front transmission call signal, to radio receiver, sends a signal that the maintainer shows up simultaneously.Information process unit (7) is by all clear.
In whole process, information process unit (7) meeting record generation alarm, the information that the maintainer replys, the maintainer reaches the spot all record complete.Managerial personnel can manage examination to the maintainer by these information, improve maintainer's work efficiency.
The utility model not only is confined to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
