A three-channel wireless remote control system

Abstract

The invention discloses a novel three-channel wireless remote control system. The system comprises a remote control and controlled equipment. The remote control comprises a wireless transceiver module, a power module connected to the wireless transceiver module and a remote control key. The wireless transceiver module adopts a CC2500 chip. The controlled equipment is provided with a receiver. The remote control and the controlled equipment are in 2.4 GHz-band communication. The system is characterized in that through customized control and communication protocol as well as the three-channel wireless remote control method formed by unique-format instruction codes composed of frame data, two or more paired controlled equipment are controlled for synchronous smooth operation, and multiple sets of differently paired controlled equipment can operate simultaneously without interrupting each other.

Description

technical field [0001] The present invention relates to the technical field of wireless remote control, in particular to a three-channel solution to solve the problem of one remote control controlling two or more paired controlled devices to work synchronously and smoothly, and at the same time satisfy multiple sets of different paired devices that can work simultaneously without interfering with each other. Wireless remote control system. Background technique [0002] With the rapid development of electronic information technology, more and more electrical products are flooding our lives. For the convenience of users, more and more electrical devices are equipped with remote control devices. Remote control equipment is an important interaction medium to realize human-computer interaction. At present, the universal remote controllers on the market mainly use the following two transmission modes to meet the problem of multi-device remote control without interfering with each...

Problems solved by technology

The disadvantage of using the same channel fixed code is that it is inconvenient to maintain after the product is damaged, and there is radio interference problem when multiple devices are used at the same time

Although the common frequency hopping code mode solves the problem of product maintenance and co-frequency interference, but because of frequency hopping, when multiple devices work at the same time, due to fast frequency hopping or co-frequency interference, it is easy to cause information loss and reduce real-time control. Not to mention that one remote control cannot be used to control two or more devices to work synchronously
