Construction site temporary power monitoring and management system

Industry background

The construction site has the characteristics of multiple types of electrical equipment, high electricity consumption, unstable working environment, dense living area personnel, and temporary use. In addition, the distance of the on-site lines is long, there are many branch lines, and there are many open contacts laid on the ground. The phenomenon of three-phase imbalance and zero ground mixing is prominent. It is difficult to manage the illegal use of electricity in the staff dormitory, and the overall energy consumption situation is complex. It not only easily causes energy waste, but also easily leads to electric shock injuries or electrical fire accidents, which makes many construction site managers very headache. The most effective way is to promote the use of technological means to improve the intelligence level of temporary electricity, strengthen the safety of temporary electricity use on construction sites, and standardize the management of energy-saving electricity use.

System Overview

Construction site temporary power monitoring and management systemTaking the temporary box transformer substation and temporary power box on the construction site as the monitoring object, it is a temporary power monitoring and management system on the construction site, which is built by installing necessary intelligent power monitoring terminals, directly or through the corresponding gateway equipment, and connecting with the cloud platform via the mobile Internet, to realize the centralized status monitoring, abnormal alarm, remote control, energy consumption management, intelligent operation and maintenance and other functional requirements of the temporary power system on the construction site, and well solve the problems of temporary power safety and energy consumption waste on the construction site. The specific structural diagram is as follows

Functions of the temporary power monitoring and management system for construction sites

Safety monitoring: Real time collection of multiple electrical parameters such as voltage, current, power, leakage current, cable temperature, electrical joint temperature, fault arc, grounding resistance, etc. of temporary power lines, achieving all-weather online monitoring of electrical operation status and safety situation.

Remote control of the switch can also be achieved through a mobile app or computer web. For example, when there is a special situation that requires an emergency power outage, relevant personnel do not need to be present on site. They only need to lightly tap on their mobile or computer devices to quickly and accurately complete the corresponding operation remotely, greatly improving work efficiency and flexibility.

Intelligent alarm: Through intelligent diagnostic analysis, it can timely detect short circuits, overcurrent, overload, overvoltage, undervoltage, leakage, overheating, surge, ignition, phase loss, and insulation abnormalities caused by grounding electrode damage or detachment. It can accurately locate the occurrence point, cause, alarm level, and time of circuit abnormalities, and send alarm information to relevant personnel through pop-up alarm screens, SMS or phone calls, APP, etc., to promptly investigate and eliminate potential faults, avoiding major safety accidents such as electrical fires.

Energy consumption management: Real time statistics of the total electricity consumption of the electrical box and the specific energy consumption data of each line, automatic calculation of electricity consumption, and timely detection of energy consumption anomalies. Not only can it display the current electricity consumption data in real time, but it can also generate detailed electricity consumption reports, clearly showing the trends and patterns of electricity consumption in different time periods, providing important basis and reference for electricity planning, cost accounting, and the formulation of energy-saving measures, which helps to achieve more scientific and reasonable electricity management and resource optimization allocation.

Intelligent operation and maintenance: The system provides 24-hour uninterrupted online inspection of equipment status, and supports intelligent management work such as daily and regular equipment inspections, task assignments, fault repairs, and defect elimination through a mobile app. It achieves rapid closed-loop processing of abnormal problems, greatly improving work efficiency and management level.

system value

Through all-weather status monitoring and remote control functions, the safety and reliability of power supply have been improved;

By adopting the O2O operation and maintenance mode, the business closed-loop management of temporary power system operation and maintenance on construction sites has been achieved, which not only improves work efficiency but also greatly reduces operation and maintenance costs.
