It closes and is connected by WIFI network with host computer, wireless VGA projection gateway is plugged in the USB interface of projector.
Further, the electronic presentation system based on Internet of Things further includes the throwing for receiving the image of projector
Shadow screen.
Further, the projection screen is projection film.
Further, the projection film is light modulation film or holographic film, and the light modulation film is to be powered to being transparent and power off in mill
The liquid crystal film of sand shape；The holographic film is transparent holographic projection film.
Further, the electronic presentation system based on Internet of Things further includes the wireless sound box for playing voice, described wireless
Speaker is connected by WIFI network with host computer or mobile phone terminal.
Further, the mobile phone terminal is connected by WIFI network or 4G network with Cloud Server.
Compared with prior art, the utility model has the beneficial effects that
1, wireless VGA projection gateway is installed, and in host computer in the USB interface of the projector in the utility model
Installing wireless network card on USB interface is removed from so that projector and host computer interconnect under the same wireless network environment
Conventional projector and host computer were avoided the arrangement of multi-line in exhibition room installation, were effectively saved by VGA line connection type
The space of exhibition room；
2, the mobile phone terminal in the utility model passes through wireless network with host computer and is connected with Cloud Server, computer master
Machine and mobile phone terminal may have access to information stored in cloud server, when host computer break down can not broadcast information when, can
To use the mobile phone being connected by wireless network with projector to play out information, the information that mobile phone terminal plays passes through wireless
VGA projection gateway, which receives and is transmitted to projector, to be launched；
3, the utility model it is logical in projection screen using light modulation film or the projection film of holographic film, dim in the operating condition
Film and holographic film are transparence, to mutually echo with exhibition room white wall, so that the dispensing for the influence cleaning that projector is launched
To being mounted on the projection film of pavilion wall, remove from and use electronic whiteboard in conventional projection system, so that chivalrous person saves space；
4, the wireless sound box in the utility model is connected by wireless network with mobile phone terminal or host computer, consequently facilitating
Audio is played simultaneously when the information of mobile phone or host computer is projected to projection screen, using the form of wireless connection, is exempted from
The laying of multi-line was gone, and the broadcasting of audio not will receive distance between mobile phone terminal or host computer and wireless sound box
Limitation；
In short, the utility model has the advantages that saving space, easy to use, broadcasting is various informative.
Detailed description of the invention
Fig. 1 is the system block diagram of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of electronic presentation system based on Internet of Things, including be stored with show the host computer of information with
And the projector for launching image information, the host computer are connected with the Cloud Server for remotely storing, the cloud clothes
Business device is connected with mobile phone terminal, and host computer is connected with input keyboard and display, is connected on the USB interface of host computer
Host computer is accessed network for realizing by wireless network by wireless network card, the wireless network card；The projector is connected with
