Description

Technical Field

[0001] This invention relates to the field of power communication technology, and in particular to an intelligent power management system for construction sites. Background Technology

[0002] Temporary power supply at construction sites is a crucial component throughout the entire construction process, and its safe management is essential for the smooth progress of the entire project. Currently, safety issues arising from temporary power supply in construction are becoming increasingly prominent. Frequent accidents caused by overloading, haphazard wiring, damaged wiring leading to short circuits, electrical leaks, and inadequate safety management are occurring frequently, creating numerous obstacles to construction. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes an intelligent power management system for construction sites.

[0004] The technical solution of this invention is implemented as follows: This invention discloses an intelligent power management system for construction sites, including a management platform, a user terminal, and a distribution box. The management platform communicates wirelessly with the distribution box and the user terminal. The distribution box is equipped with an intelligent circuit breaker, which 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 the visualization, informatization, and intelligent full-process management of construction power consumption.

[0005] Furthermore, the management platform includes a large-screen dashboard module, an electrical box monitoring module, and an electrical box management module;

[0006] The large-screen dashboard modules are used to display electricity consumption data, including project overview, distribution of electrical boxes, equipment usage, alarm status, inspection status, and other data information.

[0007] The electrical box monitoring module is used to monitor, analyze and statistically process the power consumption data of each distribution box. The power consumption data includes voltage, current, temperature, leakage current, power consumption and historical data.

[0008] The electrical box management module is used to control the opening or closing of circuits in each distribution box.

[0009] Furthermore, the management platform includes an authorized power consumption module, which is used to receive power consumption requests from user terminals and perform permission comparisons. If the requesting user has power consumption permission, the power consumption is authorized and the circuit breaker is tripped after the power consumption is completed, and the power consumption is counted. If the requesting user does not have power consumption permission, an alarm is triggered and the circuit breaker is automatically tripped.

[0010] Furthermore, the management platform includes a subcontractor electricity consumption statistics module, which is used to measure the electricity consumption of each subcontractor after the subcontractor scans the code to authorize electricity use.

[0011] Furthermore, the management platform includes an inspection management module, which includes a leakage protection test module. The leakage protection test module is used to periodically control the opening and closing operation of the circuit breaker and test whether its residual current operation is normal.

[0012] The inspection management module includes a grounding test module, which is used to detect the grounding resistance of the distribution box and test whether the grounding wire inside the distribution box is securely connected based on the resistance value.

[0013] Furthermore, the management platform includes an alarm module, a power consumption statistics module, a monthly report module, and a backend settings module;

[0014] The alarm module is used for processing and statistical analysis of alarm information from the distribution box circuit.

[0015] The power statistics module is used for overall power statistics of each circuit in the distribution box;

[0016] The monthly report module is used for monthly electricity consumption analysis and optimization suggestions.

[0017] The backend settings module is used for maintaining project information, distribution box information, and personnel information.

[0018] Furthermore, the smart circuit breaker is used to transmit the collected electricity consumption data to the 4G IoT module using the MOTT protocol, and the 4G IoT module transmits the data to the management platform in real time via 4G.

[0019] Furthermore, the distribution box is used to upload electricity consumption data to the management platform at set time intervals. The distribution box is also used to upload abnormal signals to the management platform in a trigger mode. Specifically, when there is a change in the abnormal signal, the abnormal signal is immediately uploaded to the management platform so that the management platform can analyze and process the abnormal signal.

[0020] Furthermore, the management platform is used to calculate the electrical 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 electrical load of the distribution box to its rated capacity. When the load rate of the distribution box is greater than a first preset value, the distribution box is prompted to operate in a first state. When the load rate of the distribution box is less than a second preset value, the distribution box is prompted to operate in a second state.

[0021] Furthermore, the distribution box includes a primary distribution box, a secondary distribution box, and a tertiary distribution box. The input terminal of the primary distribution box is electrically connected to the power distribution room, and the output terminal of the primary distribution box is electrically connected to the input terminals of multiple secondary distribution boxes. The primary distribution box supplies power to all secondary distribution boxes. The output terminal of the secondary distribution box is electrically connected to the input terminals of multiple tertiary distribution boxes. The secondary distribution box supplies power to the tertiary distribution boxes connected to it. The tertiary distribution boxes supply power to the electrical equipment. The management platform communicates with the secondary distribution boxes. The secondary distribution boxes are equipped with a communication module and an intelligent circuit breaker.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The intelligent power management system for construction sites of this invention collects information on various circuits of construction power supply through the circuit breaker acquisition module in the temporary distribution box. After processing by the processing module, the information is exchanged with the cloud platform through the Internet of Things. At the same time, combined with the big data analysis function of the management cloud platform, it achieves the goal of visual, information-based and intelligent full-process management of temporary power supply for construction sites.

[0024] This invention employs an intelligent power management system for construction sites, which greatly improves the level and efficiency of power safety management during construction, reduces the number of management personnel, and lowers labor costs. Furthermore, this invention can rationally adjust the layout of power boxes in areas with tight or no power supply by monitoring the real-time load of the power boxes. In addition, by combining remote switching with power consumption data, it can promptly detect equipment or line leakage and long-term no-load operation of equipment, thereby improving power consumption, reducing equipment investment, and enabling reuse.

[0025] This invention can provide real-time alarms. When an alarm occurs, the circuit breaker buzzer sounds, an alarm pop-up window appears on the platform, and the equipment administrator receives a text message or phone alarm notification simultaneously. The notification informs the equipment administrator which distribution box and which circuit in which location experienced a fault alarm, accurately locating the fault point, reducing the number of faults, enabling rapid repairs, and reducing downtime and production costs caused by power failures.

[0026] The intelligent power management system for construction sites of this invention monitors the use of electricity during construction, promptly detecting situations such as over-powering of distribution boxes, idle distribution boxes, equipment leakage, and prolonged unloaded use. Through monthly reports or early warnings, it analyzes power loss points and proposes suggested optimization schemes for power configuration, thereby improving the utilization rate of electrical energy and making it more energy-efficient and environmentally friendly.

[0027] In summary, the intelligent power management system for construction sites using this invention solves problems such as frequent electrical fires during temporary power supply in construction sites, difficulty in controlling unauthorized wiring, difficulty in implementing inspection management, difficulty in monitoring power usage, and difficulty in maintaining power supply systems in case of malfunctions.

Detailed Implementation

[0048] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] In the various figures, the same elements are represented by similar reference numerals. For clarity, not all parts in the figures are drawn to scale. Furthermore, some well-known parts may not be shown in the figures.

[0051] Many specific details of the invention, such as the structure, materials, dimensions, processing methods, and techniques of the components, are described below to provide a clearer understanding of the invention. However, as those skilled in the art will understand, the invention may be implemented without following these specific details.

[0052] This invention integrates circuit data acquisition and processing modules into a standard circuit breaker based on existing data monitoring and digitization technologies. By combining existing IoT technology with a communication module integrated into the standard circuit breaker or developing a gateway module, it enables monitoring data from all levels of temporary construction power distribution boxes and communication with the management platform. It analyzes various temporary construction power usage scenarios, establishes a targeted database on the platform, and analyzes and displays the collected and processed power usage data, transforming manual management into online, visual management. Simultaneously, it divides the platform into functional modules based on the problems to be solved, enabling standardized inspections, fault alarms, rapid fault location, big data analysis of power configuration, and power consumption statistics.

[0053] See Figure 1 This invention discloses an intelligent power management system for construction sites, including a management platform, user terminals, and distribution boxes. The management platform communicates wirelessly with the distribution boxes and user terminals. The distribution boxes are equipped with intelligent circuit breakers, which are 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 achieve visualized, information-based, and intelligent full-process management of construction power consumption at construction sites.

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

[0055] The management platform includes a large screen dashboard module, an electrical box monitoring module, an electrical box management module, an authorized power consumption module, an inspection management module, an alarm module, a power consumption statistics module, a subcontractor power consumption statistics module, a monthly report module, and a backend settings module.

[0056] The large-screen dashboard modules are used to display electricity consumption data, including project overview, distribution of electrical boxes, equipment usage, alarm status, inspection status, and other data information.

[0057] The electrical box monitoring module is used to monitor, analyze and statistically process the power consumption data of each distribution box. The power consumption data includes voltage, current, temperature, leakage current, power consumption and historical data.

[0058] The electrical box management module is used to control the opening or closing of circuits in each electrical box.

[0059] Authorized power access is used to allow specific electricians or operators to use electricity by scanning a code. When unauthorized personnel use electricity, the system will send an SMS alarm and disconnect the circuit breaker, so as to achieve the purpose of accurate statistics on the electricity consumption of the work group.

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

[0061] The alarm module is used for processing and statistical analysis of alarm information from the distribution box circuit.

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

[0063] The subcontractor electricity consumption statistics module is used to measure the electricity consumption of each subcontractor after the subcontractor scans the code to authorize electricity use;

[0064] The monthly report module is used for monthly electricity consumption analysis and optimization suggestions.

[0065] The backend settings module is used for backend management of project information, power distribution box information, personnel information maintenance, etc.

[0066] The distribution box of this invention is equipped with an intelligent circuit breaker. The intelligent circuit breaker collects power consumption data and monitors power failures in real time. When a power failure occurs, the circuit breaker body is operated to trip, which helps to protect the life and property safety of users.

[0067] The power usage status of the power distribution box for construction power carriers can be monitored in real time through circuit breakers. In case of power failure risk, alarms will be triggered to management personnel in real time, so as to find the power failure point in time for maintenance and eliminate safety risks.

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

[0069] The management platform enables multi-level management, deploying enterprise back-end management, project management, and APP terminals. It displays the power consumption status of all projects and individual projects, mainly including equipment information, load usage, power consumption statistics, alarm status, and alarm handling, facilitating the overall monitoring of power consumption.

[0070] Furthermore, the authorized power consumption module receives power consumption requests from user terminals and performs permission comparisons. If the requesting user has power consumption permission, the system authorizes power consumption and disconnects the circuit breaker after power consumption is completed, and calculates the power consumption. If the requesting user does not have power consumption permission, an alarm is triggered and the circuit breaker is automatically disconnected. Project team electricians scan a code to authorize power consumption. When unauthorized personnel use power, the system sends an SMS alarm and disconnects the circuit breaker, achieving accurate power consumption statistics for the team.

[0071] Furthermore, the inspection management module is used to display and statistically analyze inspection plans and specific inspection details in real time, in conjunction with the electricity management system. By integrating the inspection management module with the electricity management system, paperless daily electricity inspections are achieved, and the real-time display and statistical analysis of inspection plans and specific inspection details effectively ensures a closed-loop inspection process.

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

[0073] The inspection management module includes a grounding test module, which is used to detect the grounding resistance of the distribution box and test whether the grounding wire inside the distribution box is securely connected based on the resistance value.

[0074] Furthermore, the alarm module is used to issue alarm notifications when electrical safety hazards occur in the circuit, informing the user of the abnormality in which electrical circuit under which distribution box. When an electrical safety hazard occurs, the alarm information is sent in real time via platform pop-ups, SMS / telephone notifications, and device-side alarms, allowing relevant personnel to be informed immediately which electrical circuit under which device is experiencing an abnormality and to promptly eliminate the hazard.

[0075] Furthermore, the alarm notification method can be one or more of the following: platform pop-up notification, SMS notification, telephone notification, and device-side alarm.

[0076] Furthermore, the smart circuit breaker is used to transmit the collected electricity consumption data to the 4G IoT module using the MQTT protocol. The 4G IoT module then transmits the data to the management platform in real time via 4G. The MQTT data protocol is defined as follows: Figure 2 As shown.

[0077] Furthermore, the distribution box is used to upload electricity consumption data to the management platform at set time intervals. The distribution box is also used to upload abnormal signals to the management platform in a trigger mode. Specifically, when there is a change in the abnormal signal, the abnormal signal is immediately uploaded to the management platform so that the management platform can analyze and process the abnormal signal.

[0078] Furthermore, the management platform is used to calculate the electrical load of each distribution box and its load factor. The load factor of a distribution box is equal to the ratio of its electrical load to its rated capacity. When the load factor of a distribution box is greater than a first preset value, it indicates that the distribution box is operating in a first state, i.e., close to full load operation. When the load factor of a distribution box is less than a second preset value, it indicates that the distribution box is operating in a second state, i.e., low energy efficiency operation. The electrical load of a 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 to intuitively understand the electricity usage status. When the load of the electrical box exceeds a preset threshold, the management platform can automatically trigger a warning or alarm mechanism to promptly notify relevant personnel for handling.

[0080] The management platform can also model the construction site and the distribution boxes and electrical equipment within the construction site, display them through a large-screen dashboard module, and assign the status of the distribution boxes to different color zones. When the distribution box model is displayed in the first color on the large-screen dashboard module, it is also displayed in the first color when an alarm is present. When the distribution box is in the first state, it is displayed in the second color on the large-screen dashboard module, and then in the third color.

[0081] Furthermore, the distribution box includes a primary distribution box, a secondary distribution box, and a tertiary distribution box. The input terminal of the primary distribution box is electrically connected to the power distribution room, and the output terminal of the primary distribution box is electrically connected to the input terminals of multiple secondary distribution boxes. The primary distribution box supplies power to all secondary distribution boxes. The output terminal of the secondary distribution box is electrically connected to the input terminals of multiple tertiary distribution boxes. The secondary distribution box supplies power to the tertiary distribution boxes connected to it. The tertiary distribution boxes supply power to the electrical equipment. The management platform communicates with the secondary distribution boxes. The secondary distribution boxes are equipped with a communication module and an intelligent circuit breaker.

[0082] Furthermore, the management platform communicates wirelessly with the secondary distribution box, and also wirelessly with the primary and secondary distribution boxes. The primary and secondary distribution boxes are equipped with communication modules and intelligent circuit breakers, while the tertiary distribution box is equipped only with intelligent circuit breakers with multiple protection functions.

[0083] Primary distribution box: This box draws three-phase power, ground wire, and neutral wire from the transformer. It is specifically designed for the unique conditions of construction sites and complies with relevant construction power supply standards. The function of the primary distribution box is to serve as the starting point of the entire construction power system, providing power to the entire construction site. The primary distribution box is equipped with a tiered metering system, remote on / off function, local emergency stop button, power indicator, circuit monitoring, alarms, over / under voltage protection, leakage protection, and phase loss protection, meeting various usage needs. Its rainproof top design is suitable for outdoor work.

[0084] Secondary distribution box: This type of distribution box distributes power from the primary distribution box to the distribution points near the power consumption points, and is also designed for construction sites. The function of the secondary distribution box: As a transition between the primary and tertiary distribution boxes, the secondary distribution box is responsible for distributing power to specific power consumption areas or equipment. It is equipped with branch isolation, intelligent circuit breakers, and communication modules. While meeting platform data monitoring requirements, the intelligent circuit breakers also have over / under voltage protection, leakage protection, phase loss protection, and overload protection functions to ensure electrical safety.

[0085] A three-level distribution box is a control cabinet for electrical equipment itself, that is, a distribution box connected to the specific electrical load inside the building. The function of a three-level distribution box is to provide power to specific electrical equipment, lighting, sockets, etc., and to control and protect these devices or loads to meet their operational needs. Due to their high mobility, three-level distribution boxes are only equipped with functions such as leakage current protection, over / under voltage protection, and over-temperature protection to ensure the safety of personnel and equipment.

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

[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, assess the power consumption of each area based on the load rate, and obtain an optimized distribution box layout plan for each area based on the power consumption of each area. The power consumption status includes power shortage and idle status.

[0088] If the secondary distribution boxes in an area generally have a high load factor (e.g., over 90%), the area may face a power shortage. If the distribution boxes in an area generally have a low load factor (e.g., below 30%), the area may be considered a power slack area.

[0089] In some embodiments, the power consumption status of each area is assessed based on the load rate of the secondary distribution boxes in each area. Specifically, if more than a first preset value (which can be a proportion or a number, set as needed) of the secondary distribution boxes in a region have a high load rate (the load rate exceeds the first threshold, i.e., a high load rate), then the region is determined to be a power shortage area. If more than a second preset value (which can be a proportion or a number, set as needed, and the second preset value can be equal to the first preset value) of the secondary distribution boxes in a region have a low load rate (the load rate is lower than the second threshold, i.e., a low load rate), then the region is determined to be a power idle area.

[0090] The principle for optimizing the layout of distribution boxes in each region based on the power consumption situation is: reduce the number of secondary distribution boxes in areas with vacant power supply and increase the number of secondary distribution boxes in areas with high power demand.

[0091] The process of allocating secondary distribution boxes to each area includes: calculating the electrical load of each area based on the electrical equipment used; and selecting appropriate secondary distribution boxes for allocation based on the electrical load of each area.

[0092] The management platform is used to monitor the real-time load of electrical boxes, rationally adjust the layout of distribution boxes in areas with tight or no power supply, and, through remote switching and power consumption data, promptly detect equipment or line leakage and prolonged idle operation of equipment. It also analyzes and processes the power load of each distribution box, proposing optimized power configuration schemes. When equipment or line leakage or prolonged idle operation of equipment is detected, an alarm is triggered, and corresponding measures are taken.

[0093] Furthermore, the intelligent circuit breaker incorporates a data acquisition module, a data processing module, and a communication module. The data acquisition module uses miniature sensors to collect various information such as voltage, current, temperature, and leakage current during the circuit breaker's operation, converting the collected data into digital signals. The entire data acquisition module is assembled with the lower terminal of the circuit breaker, and the lower terminal of the data acquisition module is designed with the same outgoing terminal as the circuit breaker, achieving integration between the circuit breaker and the data acquisition module.

[0094] The data acquisition module 2 includes a bottom shell 21 and a cover plate 22. A phase current transformer 23 for detecting current is installed inside the bottom shell 21. The bottom shell 21 has a through hole 214 for the outgoing or incoming line of the circuit breaker body 3 to pass through. A data acquisition board is installed inside the bottom shell 21. The current transformer is electrically connected to the data acquisition board. The data acquisition board has terminals that correspond one-to-one with the outgoing or incoming terminals of the circuit breaker body 3. The cover plate 22 is located at the upper end of the data acquisition board and is fixedly connected to the bottom shell 21. The cover plate 22 has a first through hole 221 for the terminals and the outgoing or incoming line to pass through. The data acquisition board has a through hole for the outgoing or incoming line to pass through.

[0095] In some embodiments, the terminal block is welded and fixed to the data acquisition board.

[0096] In some embodiments, when the intelligent circuit breaker is a single-phase circuit breaker, the data acquisition board is provided with an L terminal, an N terminal 254, and a PE terminal 255. A phase current transformer 23 is installed inside the bottom shell 21, corresponding to the L-phase outgoing or incoming line, and the phase current transformer 23 surrounds the outside of the through hole 214 corresponding to the L-phase outgoing or incoming line.

[0097] In other embodiments, when the intelligent circuit breaker is a three-phase circuit breaker, the data acquisition board is provided with A terminal 251, B terminal 252, C terminal 253, N terminal 254, and PE terminal 255. Three phase current transformers 23 are installed inside the bottom housing 21, corresponding to the A, B, and C phase outgoing or incoming lines respectively. The three phase current transformers 23 are respectively surrounding the through-holes 214 corresponding to the A, B, and C phase outgoing or incoming lines.

[0098] Furthermore, the bottom wall of the bottom shell 21 is provided with a first receiving groove 211 for accommodating the phase current transformer 23.

[0099] Furthermore, when the intelligent circuit breaker is a three-phase circuit breaker, a zero-sequence current transformer 24 is also installed inside the base shell 21. The zero-sequence current transformer 24 surrounds the three phase current transformers 23 and is electrically connected to the data acquisition board. In this embodiment, the zero-sequence current transformer 24 surrounds the three-phase lines A, B, and C, as well as the neutral line N. Further, the zero-sequence current transformer surrounds the outgoing lines of the three-phase lines A, B, and C, as well as the outgoing line of the neutral line N.

[0100] The bottom wall of the bottom shell 21 is provided with a second receiving slot 212 for accommodating the zero-sequence current transformer 24.

[0101] Two wires are led out from the phase current transformer 23 and the zero-sequence current transformer 24, and are electrically connected to the data acquisition board through matching connectors. The data acquisition board is electrically connected to the main board through the data transmission interface 26, i.e., connector P4.

[0102] Furthermore, a hollow cylinder 213 is provided on the bottom wall of the bottom shell 21, corresponding one-to-one with the wire through hole 214 provided on the bottom wall of the bottom shell 21, and the hollow cylinder 213 communicates with the corresponding wire through hole 214. The diameter of the hollow cylinder 213 is the same as the diameter of the wire through hole 214.

[0103] In some embodiments, the bottom shell 21 includes a bottom wall and a first side wall extending upward from the edge of the bottom wall. The bottom wall and the first side wall are connected to form an open receiving cavity. The bottom wall of the bottom shell 21 has a second side wall extending upward. The second side wall is located outside the hollow cylinder 213 corresponding to the three-phase outgoing or incoming lines of A, B, and C or the L-phase outgoing or incoming line. A receiving slot for accommodating the phase current transformer 23 is formed between the second side wall and the corresponding hollow cylinder 213. The bottom wall of the bottom shell 21 has a third side wall and a fourth side wall extending upward. A receiving slot for accommodating the zero-sequence current transformer 24 is formed between the third side wall and the fourth side wall.

[0104] Furthermore, the first sidewall, second sidewall, third sidewall, and fourth sidewall are integrally formed with the bottom wall.

[0105] Furthermore, the bottom shell 21 is provided with a first connecting hole 215. The cover plate 22 is provided with a second connecting hole 224 corresponding to the first connecting hole 215.

[0106] Further, see Figure 6 The data acquisition board is equipped with connectors, including a data transmission interface 26 (connector P4) and a power interface 27 (connector P3). The cover plate 22 is provided with a second through hole 222 for the data transmission interface 26 to pass through and a third through hole 223 for the power interface 27 to pass through. The data acquisition board is equipped with a voltage sampling circuit. The input terminal of the voltage sampling circuit is connected to the corresponding terminal, and the output terminal of the voltage sampling circuit is connected to the data transmission interface. The current transformer is electrically connected to the data transmission interface on the data acquisition board via a connector.

[0107] Further, the voltage sampling circuit includes resistors R7, R14, and R21, as well as capacitors C1, C2, and C3.
