Abstract

The invention relates to a device for controlling a general-purpose serial interface in a wireless mode, in particular to a general-purpose interface control device which adopts a wireless communication protocol, such as IEEE802.15.4, Zigbee, MIWI, and the like and directly supplies power from a serial port of external control equipment. The general-purpose interface control device comprises an RF receiving and transmitting module, a serial port drive module, a serial port power supply module, and the like. The general-purpose interface control device has the control characteristics of no need of wiring, utilization during plugging, wireless communication, point-to-point and point-to-multipoint, and not only has the flexibility of wireless control, but also follows the reliability of wire control.

Description

technical field [0001] The invention relates to a device for controlling a universal serial interface in a wireless manner, in particular to a device for controlling a universal interface that adopts wireless communication protocols such as IEEE802.15.4, Zigbee, and MIWI, and takes power directly from the serial port of an external control device. Background technique [0002] Consumer electronic home appliances are usually controlled by infrared remote controllers and panel buttons. With the upgrading of home appliances and the improvement of digitalization, there are many home appliances with standard universal interfaces in the market, such as projectors, LCD Flat-panel TV, DVD player, audio power amplifier, hard disk video recorder, video and audio matrix, DMX lighting equipment, etc. [0003] Household appliances have built-in universal interfaces (such as RS232 or USB, etc.), the purpose of which is to improve the reliability of communication control (compared with inf...
