  Further, the power factor is monitored based on the measurement data, an electric facility having a low power factor with respect to the input power is extracted, and warning data to that effect is output.

  Also, by comparing the total power consumption of each facility with the power receiving source power of the distribution system by the cubicle device 60, the system loss due to resistance heat generation or leakage is monitored, and a warning, a recommended wiring size, etc. are displayed. .

  In addition, when the demand measurement and the power usage upper limit set value are expected to be exceeded, an alarm and recommendation of the power-off location are performed.

  In addition, when the process chart is input, the fuel consumption can be linked and displayed, and the relationship between the work amount and the fuel consumption can be easily grasped.

  These warning data and the like are transmitted from the transmission / reception unit 61 via the Internet 7 to the client personal computer 8 and the portable communication terminal 9 in which addresses are registered.

  Further, these measurement data and alarm data are classified into the database 63 for each facility to be measured by the identifier data and stored as history data of power consumption or fuel consumption.

  Then, a system administrator in charge accesses the management server 6 via the Internet 7 from a client personal computer 8 installed in a field office or head office, for example, and inputs authentication data such as a password to make a browsing request. Then, the authentication unit 62 in the management server 6 determines whether the authentication data matches the pre-registered authentication data, and if it matches, searches the database 63 for monitoring data such as the requested power consumption. , And output in various graphs and forms via the WEB output unit 65. For this reason, the person in charge of the system can view the monitoring data displayed on the display screen of the client personal computer 8 or the like, and can confirm the power consumption status and the fuel consumption status of each facility used for the shield construction.

For this reason, it is possible to determine whether a model with an appropriate capacity can be selected, and if it is determined that the equipment used for the construction is not an appropriate capacity, it is better from past accumulated data. select the efficiency of the model, for example electric motors, lighting equipment, introducing distribution line, the vehicle-based construction machines for construction sites introduced existing equipment such as a generator, and presents a high alternative model of saving CO ₂ effect, the alternative model It is possible to estimate and present the effect of the case.

  As explained above, according to this energy consumption reduction support system, the instantaneous electricity consumption, power factor, instantaneous fuel consumption, engine speed, etc. during construction are measured in detail for each equipment category, and the measured data Is sent directly to the management server via the Internet, processed in a batch, and displayed on the management screen on the web. This screen is managed with a password and can be viewed on a computer if there is a communication network environment. And since the measurement data of the said equipment can be posted in real time at the hand of an equipment driver using a portable terminal etc., the motivation effect of the energy-saving driving | operation by an awareness improvement can be anticipated.

  In the above-described embodiment, the case where the energy consumption reduction support system for construction work according to the present invention is applied to tunnel construction by the shield method has been described. However, the present invention is applicable to other civil engineering works and building works. Can be applied.
