[0001] The invention relates to the field of building energy-saving control for construction sites, and in particular to a building energy-saving control system for construction sites. Background Art

[0002] In today's construction industry, the problem of energy consumption at construction sites is becoming increasingly prominent. With the continuous expansion of the scale of construction projects and the increasing complexity of construction technology, the demand for various types of energy at construction sites continues to grow. However, traditional construction site energy management methods have many drawbacks. During the construction process, a large number of mechanical equipment, lighting facilities, electrical equipment in temporary offices and living areas, etc., are often lacking in effective energy-saving planning and control, resulting in serious energy waste. Due to the lack of real-time and accurate energy monitoring methods, it is difficult for managers to accurately grasp the actual energy consumption and cannot promptly discover and solve the problem of abnormal energy consumption.

[0003] With the rapid development of information technology and automation technology, sensor technology, data analysis technology, intelligent control technology, etc. have made it possible to achieve efficient energy management at construction sites. The continuous maturity and application of these technologies have made it possible to monitor energy consumption in real time, accurately analyze energy data, and intelligently control the operation of equipment, laying a solid technical foundation for the research and development and application of building energy-saving control systems for construction sites. Summary of the invention

[0004] In order to solve the technical problems raised by the above background technology, the present invention provides a building energy-saving control system for a construction site.

[0005] The purpose of the present invention can be achieved through the following technical solutions: a building energy-saving control system for a construction site, including an energy monitoring module, an environmental monitoring module, an equipment management module, an energy analysis module, an environmental analysis module, a personnel positioning and control module, a real-time scheduling module and a construction site database.

[0006] The energy monitoring module is used to collect energy at the construction site. The specific acquisition process is as follows:

[0007] By installing smart water meters at key nodes of the water supply pipeline, the water usage data of each point on the construction site can be monitored in real time through the smart water meters. The water usage data includes water volume and water flow rate.

[0008] By installing smart meters in various power consumption areas and equipment at the construction site, the smart meters monitor the power consumption data of each area and each device in real time. The power consumption data includes measured current, voltage, power, active power and reactive power parameters.

[0009] The output terminals of the smart water meter and the smart electricity meter are connected to the input terminal of the energy monitoring module, and the real-time monitored data information is uploaded to the energy monitoring module.

[0010] The environmental monitoring module is used to monitor the temperature and light intensity environmental parameters of the construction site in real time. The specific acquisition method is as follows:

[0011] The temperature parameters of each area of ​​the construction site are monitored in real time through temperature sensors to obtain the temperature parameters of each area of ​​the construction site.

[0012] The light intensity sensor is used to monitor the light intensity of each area of ​​the construction site in real time to obtain the light intensity of each area of ​​the construction site.

[0013] The equipment management module is used to register and maintain the equipment at the construction site, and manage the equipment at each construction site. The specific acquisition method is as follows:

[0014] The output end of the equipment management module is connected to the input end of the construction site database to establish an equipment information registration function, and upload the basic information of each construction site equipment to the construction site database. The basic information includes the name, model, purchase date and service life of the construction site equipment. Establish a maintenance file for the construction site equipment to record the time, content, maintenance personnel and replacement parts of each maintenance. Extract the historical maintenance records of each construction site equipment and analyze them with the current maintenance time. Sort the construction site equipment from the largest to the smallest according to the number of maintenance times, and obtain the equipment with the most maintenance times GY and the equipment with the least maintenance times GZ.

[0015] The current status of each construction site equipment is monitored through the construction site monitoring terminal. When the status of each construction site equipment is in working status, the current working hours of the construction site equipment are monitored. When each construction site equipment is in closed status, the corresponding working hours of each construction site equipment are obtained. All working hours of each construction site equipment on that day are collected in real time to obtain the total working hours TY of each construction site equipment on that day. Similarly, all closed hours of each construction site equipment on that day are collected in real time to obtain the total closed hours TZ of each construction site equipment on that day. The total working hours and total closed hours corresponding to each construction site equipment are compared with each other. If the total working hours corresponding to each construction site equipment are greater than the total closed hours, the current equipment is judged to be in working status. If the total working hours are less than the total closed hours, it is judged to be in closed status.

[0016] The total working time, total shutdown time, equipment with the most maintenance times, and maintenance times are normalized and their values ​​are taken. The formula is used The device impact value Qi is obtained, wherein b1, b2, b3 and b4 are preset proportional coefficients.

[0017] The output end of the equipment management module is connected to the input end of the analysis module, and the acquired equipment impact value is sent to the energy analysis module.

[0018] The energy analysis module is used to analyze the collected energy parameters and environmental parameters, and send the analyzed information to the personnel positioning control module and the energy optimization scheduling module. The specific acquisition method is as follows:

[0019] The output end of the energy analysis module is connected to the input end of the personnel positioning control module, and the output end of the data analysis module is connected to the input end of the energy scheduling module. The water consumption and water flow rate of each area are obtained through the smart water meter. The water consumption and water flow rate of each area are monitored in the corresponding time period through the smart water meter to obtain the water consumption and water flow rate of each area in each time period. At the same time, the time period with the largest water consumption in each area is obtained. The time period with the largest water consumption in the current area is monitored through the monitoring end. If the area corresponding to the monitoring end is displayed as an unused area, a shutdown signal is generated and sent to the personnel positioning control module. By obtaining the maximum water flow rate of each area, the standard water flow rate in the construction site database is extracted, and the maximum water flow rate is compared with the standard water flow rate. If the maximum water flow rate is greater than the standard water flow rate, it means that the water volume is normal. On the contrary, it means that the water loss is abnormal, and a loss signal is generated and sent to the personnel positioning control module.

[0020] The current t and voltage p of each construction site equipment in each area are obtained through the smart meter. The power consumption G corresponding to each construction site equipment is calculated by the formula G=t×p. The power consumption of each construction site equipment is monitored by the smart meter during the corresponding period to obtain the power consumption value {z1, z2, z3, ..., zn} of each construction site equipment at each monitoring time point, and the maximum power consumption and minimum power consumption are obtained. The power consumption difference value is obtained by subtracting the minimum value from the maximum power consumption. Then, all power consumption values ​​of each construction site equipment in the corresponding period are averaged to obtain the power consumption average value D TM , by calculating the formula The power consumption fluctuation value β is obtained, where n is represented by the number of power consumption values. The power consumption impact value corresponding to each device is constructed through the power consumption difference, average power consumption and power consumption fluctuation value of each construction site equipment. The impact value of each device in the equipment management module is extracted, and the power consumption impact value is matched with the corresponding equipment impact value. It is found that the longer the total working time of each device and the more maintenance times, the greater the corresponding power consumption impact value; the shorter the total working time of each device and the fewer maintenance times, the smaller the corresponding power consumption impact value, and an abnormal signal is generated and sent to the personnel positioning and control module.

[0021] The environmental analysis module is used to analyze the obtained environmental parameters and send the analyzed information to the real-time scheduling module. The specific acquisition method is as follows:

[0022] The input end of the environmental monitoring module is connected to the input end of the environmental analysis module, and the output end of the environmental analysis module is connected to the real-time optimization scheduling module. The temperature parameters obtained in real time are used to extract the construction site temperature threshold, and the obtained real-time temperature parameters are compared with the construction site temperature threshold. If the real-time temperature parameter is less than the construction site temperature threshold, it means that it is normal and the ventilation system of the corresponding area is turned on. Otherwise, a shutdown signal is generated and sent to the real-time scheduling module.

[0023] The light intensity of each area of ​​the construction site is obtained in real time, the preset light intensity of each area is extracted, and the real-time light intensity is compared with the preset light intensity. If the real-time light intensity is less than the preset light intensity, the light is turned on. If the real-time light intensity is greater than the preset light intensity, an energy-saving signal is generated and sent to the real-time scheduling module.

[0024] The personnel positioning and control module uses positioning technology to obtain the distribution of construction personnel on site, and then reasonably allocates energy according to the energy needs of different equipment. The specific acquisition method is as follows:

[0025] The construction personnel and maintenance personnel upload their personal information to the construction site database. The personal information includes name, mobile phone number and years of work experience. The input end of the personnel positioning control module is connected to the output end of the construction site database. The personnel positioning control module receives the shutdown signal and obtains the mobile phone terminal signal of the construction personnel within the corresponding area radius, sends the shutdown signal to the mobile phone terminal of the construction personnel, and shuts down the water source of the corresponding area through the construction personnel. The personnel positioning control module receives the loss signal and obtains the mobile phone terminal signal of the maintenance personnel currently on duty, and sends the information to the corresponding mobile phone terminal of the maintenance personnel. The maintenance personnel will inspect the corresponding abnormal water loss and feedback the maintenance results to the construction site database;

[0026] The personnel positioning module receives the abnormal signal and feeds it back to the maintenance personnel. The equipment is adjusted according to the total working time and the number of maintenance times. The equipment with fewer maintenance times is replaced to the area that requires more working time. Similarly, the equipment with more maintenance times is replaced to the area with less working time. The operating time of the equipment with more maintenance times is adjusted. When the specified operating time is exceeded, it is shut down and the equipment with fewer maintenance times is used.

[0027] The real-time scheduling module intelligently controls the lighting, ventilation and other equipment in the corresponding area based on the real-time environmental parameters. The specific acquisition method is as follows:

[0028] The real-time scheduling module receives the shutdown signal. The real-time scheduling module senses the current construction site temperature in real time through the temperature sensor. When the construction site temperature is lower than the set temperature threshold, a signal will be sent to the ventilation system in the corresponding area. The ventilation system receives the signal and shuts down.

[0029] The real-time scheduling module receives the energy-saving signal and obtains the light brightness level of the current construction site in real time through the light sensor. The light brightness is divided into five levels, including 100-1000 lux on sunny days, 5-50 lux on cloudy days, 10 lux at dusk, 300 lux at sunrise and sunset, and 0.02-0.3 lux on moonlit nights. The light brightness is adjusted according to the different light brightness obtained. The light brightness includes low brightness, medium-low brightness, medium brightness, medium-high brightness and high brightness. The light brightness is matched with the light brightness. The lower the light brightness, the higher the corresponding light brightness; the higher the light brightness, the lower the corresponding light brightness.

[0030] The construction site database will store the collected parameter data and collect personal information of maintenance personnel and workers.

The personal information includes name, mobile phone number and years of work experience. The input end of the personnel positioning control module is connected to the output end of the construction site database. The personnel positioning control module receives the shutdown signal and obtains the mobile phone terminal signal of the construction personnel within the corresponding area radius, sends the shutdown signal to the mobile phone terminal of the construction personnel, and shuts down the water source of the corresponding area through the construction personnel. The personnel positioning control module receives the loss signal and obtains the mobile phone terminal signal of the maintenance personnel currently on duty, and sends the information to the corresponding mobile phone terminal of the maintenance personnel. The maintenance personnel will inspect the corresponding abnormal water loss and feedback the maintenance results to the construction site database; The personnel positioning module receives the abnormal signal and feeds it back to the maintenance personnel. The equipment is adjusted according to the total working time and the number of maintenance times. The equipment with fewer maintenance times is replaced to the area that requires more working time. Similarly, the equipment with more maintenance times is replaced to the area with less working time. The operating time of the equipment with more maintenance times is adjusted. When the specified operating time is exceeded, it is shut down and the equipment with fewer maintenance times is used.

7. A building energy-saving control system for a construction site according to claim 1, characterized in that: The real-time scheduling module intelligently controls the lighting and ventilation equipment in the corresponding area based on the environmental parameters obtained in real time. The specific methods are as follows: The real-time scheduling module receives the shutdown signal. The real-time scheduling module senses the current construction site temperature in real time through the temperature sensor. When the construction site temperature is lower than the set temperature threshold, a signal will be sent to the ventilation system in the corresponding area. The ventilation system receives the signal and shuts down. The real-time scheduling module receives the energy-saving signal and obtains the light brightness level of the current construction site in real time through the light sensor. The light brightness is divided into five levels, including 100-1000 lux on sunny days, 5-50 lux on cloudy days, 10 lux at dusk, 300 lux at sunrise and sunset, and 0.02-0.3 lux on moonlit nights. The light brightness is adjusted according to the different light brightness obtained. The light brightness includes low brightness, medium-low brightness, medium brightness, medium-high brightness and high brightness.
