The invention relates to an event triggering type signal capturing method and system of a wireless sensor network. The method comprises the following steps: arranging a wireless sensor at a monitoring position in high-voltage power equipment, and constructing a wireless sensor network; grouping and marking the wireless sensors according to the positions of the wireless sensors; obtaining node residual energy of the wireless sensors in each group, sorting the wireless sensors according to the node residual energy from high to low, and determining a station guard node list and a station guard period of each group; determining the station guard nodes according to the number of the station guard nodes determined according to the station guard rate and the corresponding station guard node list; waking up the station guard nodes in the station guard node list; setting other wireless sensors in a dormant state, and timing the network; if the wireless sensor is captured, calculating a node awakening list when partial
