Abstract
The utility model provides a cable joint on-line monitoring system. The system comprises a monitoring terminal and at least one monitoring node. The monitoring node is arranged corresponding to a specific region. The monitoring node comprises multiple wireless sensing nodes and a center node. The wireless sensing nodes are distributed on cable joints to be monitored in a one-to-one correspondence manner. The center node is mounted within the corresponding specific region in the monitoring node. Each of the wireless sensing nodes acquires temperature data of the corresponding cable joint and transmits the temperature data outwards through a wireless sensing network. The center node corresponding to the wireless sensing nodes receives the temperature data through a long-range wireless public network, gathers the temperature data, and transmits the temperature data to a monitoring terminal through the wireless public network. The monitoring terminal receives the temperature data of each center node through the long-range wireless public network, analyzes the temperature data, and compares the temperature data with a preset temperature threshold. When the temperature data exceeds the preset temperature threshold, the monitoring terminal gives out an alarm automatically. The system is safe and reliable, and is low in cost.
