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 system also has the following disadvantages: 1. The data of the receiving end and the sending end 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 sending end is not bound to the identity of the sending end, and the data code sent is open. In the case of repeated codes, multiple sending ends can control the same receiving end
3. One-to-many control cannot be realized, because the sending end and the receiving end have been paired before leaving the factory, so one sending end cannot control multiple receiving ends of different types
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

Embodiment 1

[0026] Such as figure 1 As shown, a remote control system includes a sending end and several receiving ends, the sending end and the receiving end are wirelessly connected, the bottom layer of the sending end and the receiving end is based on the Zigbee protocol, and the entire structure and protocol are compatible with Zigbee on the market The product is compatible. The data of the sending end and the receiving end are bidirectionally transmitted. The sending end can not only control the receiving end, but the information of the receiving end can also be read back by the sending end. The data is encrypted (AES) and verified to ensure the correctness of the data. Some receivers are equipped with wireless routers, which act as network nodes for signal forwarding, that is, to transmit the signals of the transmitter to other receivers and to transmit the signals of other receivers to the transmitter.

Description

technical field [0001] The invention relates to the field of wireless remote control, in particular to a wireless remote control system. 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., typ...
