Abstract
The invention discloses a school wireless voice class grouping broadcast system comprising a controller and a plurality of voice broadcast modules. The controller is connected to a wireless emitting module through an RS232 interface, and the voice broadcast modules are connected with wireless receiving modules through the RS232 interface. Compared with the prior art, the school wireless voice class grouping broadcast system is advantageous in that the controller communicates with a classroom in a wireless manner, current school state can be prevented from being changed, an execution workload can be reduced, class grouping broadcast technologies are adopted, and management work can be reduced.
Description
Technical field
The present invention relates to communication management technical field, particularly a kind of campus wireless speech is put into several classes broadcasting system.
Background technology
The system that system employing is picked in current campus divides two kinds of patterns: one is more easy card-punching system, and not strip sowing is reported achievement can; Two is by wired pattern, main frame and each class are coupled together; Three is adopt unified report, does not possess function of putting into several classes.
Summary of the invention
The object of the invention is to provide a kind of campus wireless speech to put into several classes broadcasting system.
For achieving the above object, the present invention implements according to following technical scheme:
A kind of campus wireless speech is put into several classes broadcasting system, and comprise controller and multiple voice broadcast module, described controller connects wireless transmitter module by RS232 interface, and voice broadcast module connects wireless receiving module by RS232 interface.
As the further preferred version of the present invention, described controller is that equipment is picked in the campus of automatic acquisition network IP.
As the further preferred version of the present invention, the frequency of described wireless receiving module and wireless transmitter module is 433MHz.
Compared with prior art, controller of the present invention and classroom adopt wireless mode communication, avoid changing school's current condition, reduce implementation amount, adopt report technology of putting into several classes, reduce managerial work.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described, is used for explaining the present invention in illustrative examples of this invention and explanation, but not as a limitation of the invention.
A kind of campus wireless speech is as shown in Figure 1 put into several classes broadcasting system, comprise controller 1 and multiple voice broadcast module 4, described controller 1 connects wireless transmitter module 2 by RS232 interface, voice broadcast module 4 connects wireless receiving module 3 by RS232 interface, controller 1 is that equipment is picked in the campus of automatic acquisition network IP, and the frequency of wireless receiving module 3 and wireless transmitter module 2 is 433MHz.
Operation principle of the present invention: Word message is converted to digital signal and carries out wireless transmission according to working terminal numbering by wireless receiving module 3 and wireless transmitter module 2, each working terminal is decoded by soundplay out after receiving information again.
The present invention efficiently solves the following shortcoming of traditional product in the past:
Construction wiring problem: this product sends data to each terminal and adopts wireless mode, saves wiring.
Each terminal is reported according to terminal number automatic fitration according to the data received.
Technical scheme of the present invention is not limited to the restriction of above-mentioned specific embodiment, the technology distortion that every technical scheme according to the present invention is made, and all falls within protection scope of the present invention.
