    • A communication system includes a main control unit controlling a plurality of units, a transmitter for transmitting information between the main control unit and the plurality of units, and an error detector. The error detector can include a modulator and demodulator for modulating or demodulating the transmitted information on the basis of a predetermined rule. The error detector detects a communication error in the transmitted information in accordance with the predetermined rule. Alternatively, the error detector can include a transmitted data creator/analyzer for creating data based on the transmitted information in a state in which the information contains positive data and negative data of the same bit in one frame and analyzes data when the data is received. This error detector detects a communication error in the transmitted information on the basis of the comparison between the positive and negative data. The error detector can also include a space bit addition separator for creating data based on the transmitted information in a state in which a predetermined space bit is added in one frame and separates the space bit when the data is received. This error detector detects a communication error in the transmitted information on the basis of the timing at which the space bit and other bits appear.
    • 通信系统包括控制多个单元的主控制单元,用于在主控单元和多个单元之间发送信息的发送器和误差检测器。 误差检测器可以包括调制器和解调器,用于基于预定规则调制或解调发送的信息。 误差检测器根据预定规则检测所发送的信息中的通信错误。 或者,错误检测器可以包括用于在信息包含一个帧中的同一位的正数据和负数据的状态下基于所发送的信息创建数据的发送数据创建器/分析器,并且当接收到数据时分析数据。 该误差检测器基于正数据和否定数据之间的比较来检测所发送的信息中的通信错误。 误差检测器还可以包括用于在其中在一帧中添加预定空间位的状态下基于所发送的信息创建数据的空间位添加分离器,并且在接收数据时分离空位。 该误差检测器基于空位和其他位出现的定时检测发送信息中的通信错误。
