Abstract
The invention discloses a communication processing method and a device. A maintenance end of a communication terminal is communicated with the communication terminal through serial port lines or network lines. The method comprises the steps that: S1, configuration parameters in a communication protocol in the communication terminal are configured according to a self-defined maintenance protocol; and S2, the communication terminal submits remote signaling deflection data to a master station according to the communication protocol. Because the configuration parameters in the communication protocol in the communication terminal are configured according to the self-defined maintenance protocol, the communication processing method and the device are simple to operate and are friendly in interface. Meanwhile, on the basis that standard protocols are absolutely followed, processing for abnormal situations is added responding to the communication protocol from the communication terminal, and even if the master station sends abnormal messages or messages which do not follow an established protocol, the communication terminal can still normally response, and therefore stability of communications is guaranteed. In addition, a storage mechanism is adopted to ensure that important data are not lost when a system is free of electricity, and communication data are guaranteed to be correct.
