Multichannel WIFI wireless numerical control based on electrical apparatus physical keys

Abstract

The invention discloses multichannel WIFI wireless numerical control based on electrical apparatus physical keys. The multichannel WIFI wireless numerical control comprises a shell of an electrical apparatus such as a digital camera or a camera without a WIFI function, a PCB, an analog-to-digital conversion IC, an analog switch IC and a central processing unit CPU. The analog-to-digital conversionIC is used for converting audios / videos. The audios / videos converted by the analog-to-digital conversion IC are further transmitted to the central processing unit CPU for processing. The physical keys on mainboard of the digital camera or the camera are bidirectionally connected with the analog switch IC through FPC flexible flat cables. Bidirectional switching between high and low frequency signals is realized through setting of a control module IC. Signals in an ROM cache IC are transmitted to a WIFI bidirectional transceiving chip and then are transmitted through an antenna, and IP addresses are generated. Moreover, maximally, 14 ways of analog-to-digital conversion control can be realized at the same time, and the connection with various electrical apparatuses such as the traditionaldigital camera or the camera without the WIFI function is facilitated.

Description

technical field [0001] The invention relates to the technical field of wireless image transmission and data transmission, in particular to multi-channel WIFI wireless numerical control based on physical buttons of electrical equipment. Background technique [0002] Traditional electrical equipment without WIFI function completes the operation process through physical buttons on the fuselage or through a wired connection to the console. This control method is very inconvenient, resulting in extremely poor user experience. The Internet of Things has become a trend, but in the actual work and production process, many electrical equipment can still be used normally, if left unused, especially for some expensive electrical equipment, it may cause a great waste of resources. [0003] Designing and developing a hardware module and APP that can realize wireless data transmission between traditional electrical equipment without WIFI function and smart phone is an inevitable requireme...

AI Technical Summary

Problems solved by technology

In order to overcome the deficiency that the existing electrical equipment without WIFI cannot be connected to the smart phone, the invention provides a multi-channel wireless data transmission module, which can not only transmit the physical key signal to the smart phone when the electrical equipment is working, to realize wireless remote Operation, and can realize the switch machine of wireless control equipment
