With the development of power grid intellectualization, real-time state monitoring of power cable outer sheath is becoming more and more important. Monitoring and test of the cable outer sheath currently being used are time consuming and inflexible. To this point, a DigiMesh network based wireless monitoring solution is proposed in this article. The sensor node is mainly composed of main control chip Msp430F169 and XTend module based on DigiMesh network. It is being used to receive, store and transmit the collected data and information, and pass back the outer sheath state monitoring data through multiple hop transmission. During this process, the multi-channel and multi-data source parallel transmission mechanism is applied to reduce the route hop number and lower the network load. The proposed solution was experimental simulated, which proved to be practical and had a good real-time performance. This solution is also applicable to state monitoring of cable outer sheath in areas which are not covered by telecom signals, and it is helpful to discover and handle the cable line fault and reduce safety hazards.
