A method, device and client terminal device for improving the reliability of a device having a plurality of modules. The method comprises: a first module, according to the condition of control command interaction with a second module, determines whether a control link between the first module and the second module is abnormal; the first module sends a ping request packet to the second module, so that the second module sends a ping response packet to the first module according to the ping request packet sent by the first module; according to the condition of the received ping response packet, the first module determines whether a data link between the first module and the second module is abnormal; when it is determined that the control link and/or the data link are abnormal, the first module restarts. The described technical solution combines operating features of a device having a plurality of modules, monitors the communication reliability of the control link and the data link between the modules, not only determines problems caused by the modules themselves being abnormal, but also determines problems between the modules caused by synchronisation being abnormal, and performs recovery in a timely manner. |
