8. a kind of sensing network node state energy consumption monitoring as claimed in claim 4 system, it is characterized in that: each described node energy consumption monitoring means adopts and Monitoring Data is sent to described monitoring centralized unit again after whole observation process is finished, after treating that whole observation process finishes, realize information interaction between described node energy consumption monitoring means and the described monitoring centralized unit by described node monitoring telecommunication circuit.
9. sensing network node state energy-consumption monitoring method as monitoring system as described in any one of the claim 1～8, its step is as follows:
(1) each node energy consumption monitoring means of initialization and monitoring centralized unit, the monitoring centralized unit is sent the monitoring sign on to each node energy consumption monitoring means;
When (2) each node energy consumption monitoring means receives the monitoring sign on, drive the relay adhesive by the triode in the control/energy consumption monitoring circuit, each wireless sensor network node is connected each node battery respectively, starts working; Monitor the communication conditions of each wireless sensor network node by node monitoring telecommunication circuit, write down operating state, energy consumption and the corresponding time value of each wireless sensor network node according to preset rule, and be sent to processor, processor obtains each node battery, each wireless sensor network node change in voltage situation data, and is kept in the memory;
(3) monitoring result transfers to the monitoring centralized unit by the datel circuit of each node energy consumption monitoring means;
(4) reach preset value or monitor each wireless sensor network node and quit work when each node energy consumption monitoring means monitors each node cell voltage, or receive the halt instruction that the monitoring centralized unit sends, then each node energy consumption monitoring means quits work.
