A hydraulic model of the network is used that describes the structural data and the laws governing the distributed flows. The model is fed with operational data relative to primary input parameters and, using the model, theoretical values are obtained for primary output parameters. The theoretical values are compared with measured values. In case of a significant deviation, the corresponding primary output parameter becomes a secondary input parameter in an inverse model including new secondary output parameters, which are added relative to the direct model and which correspond to primary input parameters. The secondary output parameters are, by priority, those to which the primary output parameter exhibiting the abnormal value is particularly sensitive. If necessary, the method is implemented iteratively by progressively restricting the number of the secondary output parameters.

A power management system and method including a normally-open switch, an on/off circuit, a microprocessor, and at least one sensor to monitor a condition. The on/off circuit includes an on/off control gate-controlled switch device such as a PMOS device for system power, a flip/flop switch to respectively activate and deactivate the on/off control PMOS device, and a transition detection circuit connected to the normally-open switch. A single DC power source establishes a source voltage to power the on/off circuit and the normally-open switch. The transition detection circuit generates an on signal when the user initially activates the normally-open switch, and supplies the on signal to the flip/flop switch to change it to an on state to activate the on/off control PMOS device. While activated, the on/off control PMOS device enables system power from the power source to be provided to at least the sensor and the microprocessor. The microprocessor generates an off signal when the normally-open switch is activated for at least a selected period of time, and supplies the off signal to the flip/flop switch to change it to an off state to deactivate the on/off control PMOS device and thereby disable system power to at least the sensor and the microprocessor.

The data-accepting part accepts normal time information data and non-normal time information data, which are outputted from measurement equipment connected to the management apparatus, the data-identifying part identifies the normal time information data and the non-normal time information data based on the difference in the transmission path of the data, or based on identification information given to the data, and the data-output part outputs the above-mentioned normal time information data and the non-normal time information data, such that an operator identifies the information data.
