Wireless remote controller

Abstract

The invention relates to a wireless remote controller and aims at providing a wireless remote controller. The remote controller has strong antijam capability, and can realize one to more control or more to one control. The invention has the technical scheme that the wireless remote controller is provided with a microprocessor chip, a keyboard, a wireless receiving and transmission module and an antenna, the keyboard is connected with an I / O opening of the microprocessor chip in a matrix mode, the wireless receiving and transmission module is connected with the microprocessor chip, the antenna is connected with the wireless receiving and transmission module, and the memory of the microprocessor chip has an MAC address corresponding to the wireless remote controller. The wireless remote controller has the MAC address which is unique in the world and is to be used as fingerprints for identifying binding identity with a controlled device. One wireless remote controller can realize the reliable remote control of a plurality of controlled devices by saving one MAC address of the wireless remote controller in the controlled devices.

Description

technical field [0001] The invention relates to the field of wireless remote control, in particular to a wireless remote control. technical background [0002] Use the wireless method to complete the remote control operation. The common ones are wireless remote control switch light, wireless remote control various electric toys, wireless remote control door switch, switch lock, wireless remote control car anti-theft alarm and various industrial wireless remote control, etc. The wireless remote control is divided into two parts: sending and receiving. The sending part is the wireless remote control. Its principle is to encode the control command and send it out through modulation. After the receiving circuit receives the remote control signal, it obtains the control command through decoding, remote control coding and decoding. It is further divided into two types: fixed encoding and rolling encoding. Typical fixed encoding chips such as PT2262, V1526, RT6588, etc., typical ro...

AI Technical Summary

Problems solved by technology

[0003] Fixed-code and rolling-code remote control devices have their own characteristics. Fixed-code chips are cheap, but the number of address codes is small. For example, the most used PT2262 on the market has only 6561, and the probability of repeated codes is high.

Rolling coding chip has low probability of recoding and good anti-cracking performance, but the price is more expensive, and it must be "code-checked" before it can be put into work, which is relatively troublesome

[0004] The above-mentioned remote control also has the following disadvantages: 1. The data of the receiving end and the wireless remote control are pre-written in the program, which is not easy to change, and does not meet any standards

2. It is easy to send signal interference, because the signal sent by the wireless remote control is not bound to the identification of the wireless remote control, and the data code sent is open. In the case of repeated codes, multiple wireless remote controls can control the same receiving end

3. One-to-many control cannot be realized, because the wireless remote control and the receiving end have been paired before leaving the factory, so one wireless remote control cannot control multiple different types of receiving ends

4. Networking between multiple remote control devices is not possible, because the data transmission does not conform to any protocol, so the protocol networking between devices cannot be carried out
