对码方法

Code method

1、编码方式

1, encoding method

无线电遥控常用的编码方式有两种类型，即固定码与滚动码两种，滚动码是固定码的升级换代产品，目前凡有保密性要求的场合，都使用滚动编码方式。滚动码编码方式有如下优点：

There are two kinds of coding methods for radio remote control, that is, two kinds of fixed codes and rolling codes. Rolling codes are upgrading products of fixed codes. Nowadays, rolling codes are used in all occasions where security requirements are required. The rolling code coding has the following advantages:

1、保密型强，每次发射后自动更换编码，别人不能用侦码器获得地址码；

1. The security is strong. After each launch, the code is replaced automatically. Other people can't use the detector to get the address code.

2、编码容量大，地址码数量大于10万组，使用中重码的概率极小

2. The coding capacity is large, the number of address codes is more than 100 thousand groups, and the probability of using medium weight code is minimal.

3、对码容易（详见三、配遥控器的方法），滚动码具有学习存储功能，不需动用烙铁，可以在用户现场对码，而且一个接收器可以学入多达个不同的发射器，在使用上具有高度的灵活性；

3, the code is easy (see three, with the remote control method), rolling code has learning and storage function, and does not need to use soldering iron. It can learn many different transmitters on the user site code, and a receiver, and has high flexibility in use.

4、误码小，由于编码上的优势，使得接收器在没有收到本机码时的误动作几乎为0。

4, small error code, due to the advantages of the coding, the receiver in the absence of the local code when the misoperation is almost 0.

固定码编码方式有如下优缺点：

The fixed code coding method has the following advantages and disadvantages:

1、固定码的编码容量仅为6561个，重码概率极大；

1, the coding capacity of the fixed code is only 6561, and the probability of heavy code is great.

2、其编码值可以通过焊点连接方式被看出，或是在使用现场用“侦码器”来获取，所以不具有保密性，主要应用于保密性要求较低的场合；

2, its coding value can be seen through the connection of solder joints, or is used in the field with "detector code" to obtain, so it is not confidential, and it is mainly applied to occasions with low security requirements.

3、因为其价格较低所以也得到了大量的应用；

3, because of its low price, so it has also been a large number of applications.
