Background technology

At present, common RF remote-controlled switch encoding/decoding device on the market, its coded system generally has following two kinds: ternary coding and rolling coding.The encoding/decoding device that adopts ternary coded system to constitute, its encoder is necessary the same with the three-state (high level, low level or unsettled) of the address wire of decoder, otherwise encoder just can not instruction decoder work.Yet, this encoding/decoding device, though the user can adjust the coding pattern of encoder at any time, a decoding device can only submit to an encoder job, the decoding device use that can't match with the encoder of a plurality of different coding patterns, its interchangeability and versatility are relatively poor.And the encoding/decoding device that adopts the rolling coding mode to constitute, its decoder is to adopt the self study pattern, encoder is to digital code information of decoder output, decoder becomes identification code by this recording digital code of operation handlebar to erasable key in memory, encoder also can only send the number ability instruction decoder work identical with identification code, and its decoder can store a plurality of identification codes, realizes the use that matches of a decoder and a plurality of encoder.But, the encoder that the rolling code coding form constitutes, its coding pattern all is integrated in when dispatching from the factory on the IC chip of device, the user can't change, and when encoder damaged, the user needed the identification code of decoder is reset after heavily changing new encoder, troublesome poeration, the exchange inconvenience of product.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of encoding/decoding device of the RF remote-controlled switch simple and convenient, that interchangeability is strong of encoding is provided.

Goal of the invention of the present utility model is achieved in that a kind of RF remote-controlled switch encoding/decoding device, comprise encoder, it is characterized in that: a: encoder is the encoder that ternary coded system constitutes, comprise power subsystem and little processing IC, little processing IC is provided with the rf transmitter unit that is connected with little processing IC respectively, ternary selected cell and control command key module outward, wherein, little processing IC, radio frequency generating unit, ternary selected cell and control command key module all also are electrically connected with power subsystem;
