On-site electric energy intelligent management system for construction projects

Abstract

The invention discloses a construction site electric energy intelligent management system, including: a signal acquisition module, a hardware module 1, a hardware module 2, a DTU module, a temporary power load monitoring and control module, a data transmission module, a cloud platform and a display module; The signal acquisition module collects the voltage signal of each equipment terminal and the current signal collected by the current transformer, and transmits the processed data to the hardware module 1, the hardware module 2 and the temporary power load monitoring control module, and the hardware module Receive the data transmitted by a pair of signal acquisition modules, and transmit the received data to the DTU module, the second hardware module processes the power parameters transmitted by the signal acquisition module, classifies the faults according to the processing results, and The fault data and solutions are transmitted to the DTU module, and the DTU module receives and analyzes the instructions transmitted by the data transmission module, and sends the data analysis to the hardware module one.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an intelligent management system for on-site electric energy of construction engineering. Background technique [0002] At present, the power management in engineering projects is mainly based on the statistical analysis of manual inspection records, that is, to arrange manual inspections of power distribution cabinet data at all levels and record them at fixed points, and to organize and archive all the data, and then according to each time The data recorded at the point can be used to infer the overall comprehensive power consumption situation, and then artificially carry out power scheduling management according to the power consumption situation to achieve the purpose of saving power consumption, but the accuracy, real-time and reliability of power data cannot be guaranteed. [0003] The existing intelligent management system for electric energy on site in co...

[0002] At present, the power management in engineering projects is mainly based on the statistical analysis of manual inspection records, that is, to arrange manual inspections of power distribution cabinet data at all levels and record them at fixed points, and to organize and archive all the data, and then according to each time The data recorded at the point can be used to infer the overall comprehensive power consumption situation, and then artificially carry out power scheduling management according to the power consumption situation to achieve the purpose of saving power consumption, but the accuracy, real-time and reliability of power data cannot be guaranteed

[0003] The existing intelligent management system for electric energy on site in construction projects uses manual inspection to record electric energy data, which is prone to negligence and errors in the recording process, and can only record data at each inspection time point, which is not conducive to electric energy scheduling and analysis, which reduces the accuracy of electric energy data, low timeliness, and the failure to alarm for electrical faults, so that managers cannot protect the faulty circuit in time, which is not conducive to the later repair and maintenance of electrical equipment, and lacks temporary Tracking and control of electricity safety. When temporary irregularities in electricity use occur on the construction site, such as unauthorized connections, the management system cannot provide timely alarms and controls, which reduces the safety of the management system.
