Problems solved by technology
The first type of voice power amplifier mainly senses the voice signal through a wired microphone, and then sends the voice signal to a large power amplifier and speaker system through a cable for amplification and output. It has the advantages of large output voice power, wide coverage and good voice effect. , and the disadvantage is that the microphone and power amplifier are connected by a wired cable, the range of movement is limited, and it is not convenient for handheld use during movement
The microphone of the second voice power amplifier is still connected to the small power amplifier and the speaker through a cable and powered by a battery. Disadvantages, and the output voice power and coverage are limited and the sound quality is average
However, the PPT remote controller and the wireless microphone are now two independent devices that often need to be used together and operated separately, which brings inconvenience to the user to a certain extent. It can be seen that combining the wireless microphone and the PPT remote control page turning function Two for one is very necessary

The invention discloses a WiFi-based remote control system with microphone and PPT paging functions. The WiFi-based remote control system comprises a signal sensing and WiFi sending joint module, a LabVIEW-based GUI module and a USB communication module, wherein the signal sensing and WiFi sending joint module is connected with the LabVIEW-based GUI module through WiFi; the LabVIEW-based GUI module is connected with the USB communication module through a USB data line. The WiFi-based remote control system with microphone and PPT page-turning functions provided by the invention is convenient to use and operate, can directly use a wireless microphone function for voice amplification after a power supply is turned on, and can control PPT page-up and page-down by pressing buttons.
Description
technical field [0001] The invention belongs to the technical field of remote control application equipment, and in particular relates to a remote control system based on WiFi with microphone and PPT page turning functions. Background technique [0002] PPT is the abbreviation of Power Point, and Power Point is one of the important components of the office software series produced by Microsoft Corporation of the United States. Due to the wide use of PPT, the PPT remote control is produced as an electronic product specially designed for computers and multimedia projectors. The PPT remote control allows PPT users not to stay by the computer all the time. When the user is teaching, meeting, reporting or giving a speech, he only needs to press the page up and page down keys lightly to turn the electronic document to the page to be presented. This product has been widely used in various industries. [0003] When PPT is in use, a voice power amplifier is usually configured to co...
