[0052] The present invention integrates the circuit data acquisition module and the circuit data processing module into an ordinary circuit breaker based on the existing data monitoring technology and digital technology.

[0053] See also Figure 1 The embodiment of the present invention discloses an intelligent power management system for a construction site, including a management platform, a user terminal, and a distribution box. The management platform communicates wirelessly with the distribution box and the user terminal. An intelligent circuit breaker is provided in the distribution box. The intelligent circuit breaker is used to collect construction power consumption data and transmit it to the management platform. The management platform is used to perform big data analysis on the construction power consumption data to realize visualization, informatization, and intelligent management of the entire process of construction power consumption at the construction site.

[0054] The management platform may be a cloud platform.

[0055] The management platform includes a large screen billboard module, an electric box monitoring module, an electric box management module, an authorized electricity module, an inspection management module, an alarm module, an electricity statistics module, a subcontractor electricity statistics module, a monthly report module and a background setting module;

[0056] The large screen signboard modules are used to display electricity consumption data, including project overview, distribution of power boxes, equipment use, alarm status, inspection status and other data information;

[0057] The power box monitoring module is used to monitor and analyze the power consumption data of each distribution box, including voltage, current, temperature, leakage current, power consumption and historical data;

[0058] The power box management module is used to control the opening or closing of each distribution box circuit;

[0059] Authorized power supply is used to allow specific electricians or operators to use electricity through the method of scanning code authorization. When unauthorized personnel use electricity, the system will send a text message alarm and trip the switch to achieve the purpose of accurate electricity consumption statistics for the team.

[0060] The inspection management module is used for daily electricity consumption inspection of each distribution box;

[0061] The alarm module is used for the processing and statistics of alarm information of the distribution box circuit;

[0062] The electricity consumption statistics module is used for the overall electricity consumption statistics of each circuit of the distribution box;

[0063] The subcontractor electricity consumption statistics module is used for measuring the electricity consumption of each subcontractor after subcontracting for scanning code authorization to use electricity;

[0064] The monthly report module is used for monthly electricity consumption analysis and optimization suggestion plan;

[0065] The background setting module is used for background management such as project information, distribution box information, and personnel information maintenance.

[0066] The distribution box of the present invention is provided with an intelligent circuit breaker, which collects electricity consumption data through the intelligent circuit breaker and monitors electricity consumption faults in real time. When an electricity consumption fault occurs, it manipulates the circuit breaker body to trip, which is convenient for protecting the life and property safety of users.

[0067] The electricity consumption status of the construction electricity carrier distribution box can be monitored in real time through the circuit breaker. When there is a risk of electricity consumption fault, it will alarm the management personnel in real time, and timely find the electricity consumption risk fault point for maintenance to eliminate safety risks.

[0068] The electric box monitoring module mainly monitors and analyzes and statistics the electricity consumption data (voltage, current, temperature, leakage current, electricity consumption, etc.) of each distribution box.

[0069] The management platform realizes multi-level management, deploying enterprise background management level, project management level and APP side, and respectively displays the electricity consumption conditions of all projects and individual projects, mainly including equipment information, load usage, electricity consumption statistics, alarm conditions, alarm handling, etc., which is convenient for the supervision of the overall electricity consumption situation.

[0070] Furthermore, the authorized power supply module is used to receive the power consumption request of the user terminal and perform permission comparison. If the requesting user has the power consumption permission, it will authorize the power supply and trip the switch after the power consumption is completed, and count the power consumption. If the requesting user does not have the power consumption permission, it will alarm and control the automatic tripping. The electricians of the project team scan the code to authorize the power supply. When unauthorized personnel use electricity, the system will send a text message alarm and trip the switch to achieve the purpose of accurate electricity consumption statistics for the team.

[0071] Further, the inspection management module is used to combine the electricity consumption management system to display and statistically analyze the inspection plan and the specific inspection situation in real time. By combining the electricity consumption management system, the inspection management module conducts paperless daily electricity inspections, displays and statistically analyzes the inspection plan and the specific inspection situation in real time, which can effectively ensure the closed-loop of the inspection tasks.

[0072] Further, the management platform includes an inspection management module, and the inspection management module includes a residual current protection (RCD) test module. The RCD test module is used to periodically control the opening and closing operation of the circuit breaker (such as opening and then closing) to test whether the residual current operation is normal.

[0073] The inspection management module includes a grounding test module. The grounding test module is used to detect the grounding resistance of the distribution box and test whether the grounding wire in the distribution box is securely connected according to the value of the grounding resistance.

[0074] Further, the alarm module is used to give an alarm notification when there are electrical safety hazards in the circuit, so as to inform the user which electrical circuit under which distribution box has what kind of abnormality. When there are electrical safety hazards in the circuit, the alarm information is pop-up on the platform in real time, and is notified by SMS / phone call and on the device side. Relevant personnel can learn in time which electrical circuit under which device has what kind of abnormality and eliminate the hidden danger in time.

[0075] Further, the alarm notification method is one or more of platform pop-up notification, SMS notification, phone call notification, and device-side alarm.

[0076] Further, the intelligent circuit breaker is used to transmit the collected electricity consumption data to the 4G Internet of Things module using the MQTT protocol, and the 4G Internet of Things module transmits the data to the management platform in real time via 4G. The definition of the MQTT data protocol is as Figure 2 shown.

[0077] Further, the distribution box is used to upload the electricity consumption data to the management platform at regular intervals, and the distribution box is used to upload the abnormal signal to the management platform in a trigger mode, specifically including: when the abnormal signal changes, immediately upload the abnormal signal to the management platform for the management platform to analyze and process the abnormal signal.

[0078] Further, the management platform is used to calculate the electricity load of each distribution box and calculate the load rate of the distribution box. The load rate of the distribution box is equal to the ratio of the electricity load of the distribution box to the rated capacity. When the load rate of the distribution box is greater than the first preset value, it is prompted that the distribution box is operating in the first state, that is, close to the full-load operation state. When the load rate of the distribution box is less than the second preset value, it is prompted that the distribution box is operating in the second state, that is, the energy efficiency is low. The electricity load of the distribution box refers to the total power consumed by the electrical equipment connected to the distribution box within a certain period of time.

[0079] The management platform can also process and analyze the collected data to generate charts such as load curves and load rate statistics, helping users intuitively understand the power consumption situation. When the load of the electrical box exceeds the preset threshold, the management platform can automatically trigger an early warning or alarm mechanism to notify relevant personnel for handling in a timely manner.

[0080] The management platform can also model the construction site, the distribution boxes and electrical equipment within the construction site, display them through the large-screen dashboard module, and allocate the status of the distribution boxes through different colors. When the distribution box model is displayed in the first color in the large-screen dashboard module and there is an alarm, the distribution box model is displayed in the first color in the large-screen dashboard module. When the distribution box is operating in the first state, the distribution box model is displayed in the second color in the large-screen dashboard module, and the distribution box model is displayed in the third color in the large-screen dashboard module.

[0081] Furthermore, the distribution box includes a first-level distribution box, a second-level distribution box and a third-level distribution box. The input end of the first-level distribution box is electrically connected to the power distribution room. The output end of the first-level distribution box is electrically connected to the input ends of multiple second-level distribution boxes. The first-level distribution box supplies power to all the second-level distribution boxes. The output end of the second-level distribution box is electrically connected to the input ends of multiple third-level distribution boxes. The second-level distribution box supplies power to the third-level distribution boxes connected to it. The third-level distribution box supplies power to the electrical equipment. The management platform communicates with the second-level distribution box, and a communication module and an intelligent circuit breaker are provided in the second-level distribution box.

[0082] Furthermore, the management platform communicates wirelessly with the second-level distribution box, and the management platform communicates wirelessly with the first-level distribution box and the second-level distribution box. A communication module and an intelligent circuit breaker are provided in the first-level distribution box and the second-level distribution box, and only an intelligent circuit breaker with multiple protection functions is provided in the third-level distribution box.

[0083] First-level distribution box: It introduces three-phase power, ground wire and neutral wire from the transformer. It is specially designed for the special situation of the construction site and complies with the relevant construction electricity specification standards of the construction department. Function of the first-level distribution box: As the starting point of the entire construction electricity system, it provides power for the entire construction site. The first-level distribution box is equipped with functions such as a hierarchical metering system, remote opening and closing function, local emergency stop button, power indication, loop supervision, alarm and over- and under-voltage protection, leakage protection, and open-phase protection, which can meet various usage requirements. At the same time, its rainproof box top design is suitable for field work.

[0084] Secondary distribution box: It distributes the power supply line from the primary distribution box to the distribution box near the power consumption point and is also designed for the construction site. Function of the secondary distribution box: As a transition between the primary distribution box and the tertiary distribution box, the secondary distribution box is responsible for distributing power to each specific power consumption area or equipment. It is equipped with branch isolation, intelligent circuit breakers, and communication modules. Under the condition of meeting the platform data supervision, the intelligent circuit breaker also has protection functions such as over- and under-voltage protection, leakage protection, open-phase protection, and overload protection to ensure power consumption safety.

[0085] Tertiary distribution box: The control cabinet of the electrical equipment itself, that is, the distribution box connected to the specific electrical load inside the building. Function of the tertiary distribution box: It provides electrical energy for specific electrical equipment, lighting, sockets, etc., and controls and protects these devices or loads to meet their operating requirements. Due to its large mobility, the tertiary distribution box is only equipped with functions such as leakage protection, over- and under-voltage protection, and over-temperature protection to ensure the safety of power consumption personnel and equipment.

[0086] Furthermore, the management platform is used to analyze and process the power consumption load of each distribution box and propose a reasonable power consumption configuration plan.

[0087] The management platform is used to divide the construction site into areas, allocate secondary distribution boxes to each area, calculate the load rate of the secondary distribution boxes in each area, evaluate the power consumption status of each area according to the load rate of the secondary distribution boxes in each area, and obtain an optimized distribution box layout plan for each area according to the power consumption status of each area. The power consumption status includes power consumption tension status and idle status.

[0088] If the secondary distribution boxes in an area generally have a high load rate (for example, exceeding 90%), then this area may face a situation of power consumption tension. If the distribution boxes in an area generally have a low load rate (for example, below 30%), then this area may be regarded as an idle area for power consumption.

[0089] In some embodiments, evaluating the power consumption status of each area according to the load rate of the secondary distribution boxes in each area specifically includes: If more than a first preset value (which can be a ratio or a quantity, set according to needs) of the secondary distribution boxes in an area have a high load rate (the load rate exceeding the first threshold is a high load rate), then it is determined that this area is a power consumption tension area. If more than a second preset value (which can be a ratio or a quantity, set according to needs, and the second preset value can be equal to the first preset value) of the secondary distribution boxes in an area have a low load rate (the load rate below the second threshold is a low load rate), then it is determined that this area is an idle area for power consumption.

[0090] The principle of optimizing the distribution box layout plan for each area according to the electricity consumption status of each area is as follows: reduce the secondary distribution boxes in the areas with idle electricity consumption and increase the secondary distribution boxes in the areas with tight electricity consumption.

[0091] Allocate secondary distribution boxes for each area, specifically including: calculate the electricity load of each area according to the electrical equipment in each area. Select appropriate secondary distribution boxes for allocation according to the electricity load of each area.

[0092] The management platform is used to monitor the real-time load of the electrical boxes, reasonably adjust the layout of the distribution boxes in the areas with tight and idle electricity consumption, and through the combination of remote switching on and off and electricity consumption data, it can timely detect the leakage of equipment or lines and the long-term no-load operation of equipment, timely analyze and process the electricity load of each distribution box, and propose an optimized electricity allocation plan. When detecting the leakage of equipment or lines and the long-term no-load operation of equipment, give an alarm prompt and take corresponding measures.

[0093] Furthermore, a data acquisition module, a data processing module and a communication module are provided in the intelligent circuit breaker. The data acquisition module collects various information such as voltage, current, temperature, leakage power, etc. during the operation of the circuit breaker through a micro sensor, and converts the collected data into digital signals.
