[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] In order to solve the problem that the remote control of large-scale busbar plug-in boxes in factories, buildings, etc. in the prior art is relatively scattered, the remote operation is inconvenient, and the available functions are single. The present invention provides a busbar plug-in box control system for the centralized control of building busbar plug-in boxes, a master controller is set to centrally and remotely control each branch busbar plug-in box, and a power consumption monitor and a busbar joint monitor are set in each branch busbar plug-in box to respectively monitor the power consumption information and temperature information of the corresponding branch busbar plug-in box, and send the power consumption information and temperature information to the master controller through the gateway. The master controller also uploads the received power consumption information and temperature information to the background server, so as to obtain safety prevention information and fault alarm information through the background server's analysis of the power consumption information and temperature information, wherein the temperature information includes the busbar duct temperature and the connector temperature, so that accurate safety forecasts can be made based on the power consumption information, the busbar duct temperature and the connector temperature, and the temperature collection point is expanded to the busbar duct, which can improve the temperature-based safety forecast capability and improve safety, and the master controller can centrally and remotely control the opening and closing of each branch busbar plug-in box, which can effectively improve the convenience of control.

[0029] Specifically, Figure 1 As shown, it is a schematic diagram of the module architecture of the busbar plug-in box control system in this embodiment, which includes a master controller 10, and a power consumption monitor 21 and a busbar joint monitor 22 arranged in each branch busbar plug-in box 01 of the building busbar plug-in box. The master controller 10 is used for remote control of the opening and closing of each branch busbar plug-in box 01.

[0030] The power consumption monitor 21 is used to monitor the power consumption information of the corresponding branch busbar plug-in box, and send the monitored power consumption information to the main controller 10 through the gateway. The power consumption information includes current, voltage, harmonics, power and power consumption.

[0031] Among them, current and voltage are key indicators for measuring basic electrical parameters in power systems. They are used to directly reflect the operating status of power systems, ensure the normal operation of power equipment, and monitor anomalies such as overload and short circuit, so as to take corresponding measures to avoid equipment damage and reduce the risk of safety accidents.

[0032] Harmonics are used to monitor the stability of power systems and the safe operation of equipment. By monitoring and analyzing harmonics, harmonic problems caused by nonlinear loads can be discovered in a timely manner, and measures can be taken to reduce the impact of harmonics on equipment and protect equipment from damage.

[0033] By monitoring active power and reactive power, the energy consumption of the equipment can be evaluated, and the operation mode of the equipment can be optimized to improve energy utilization efficiency.

[0034] Electricity consumption is directly used to measure the energy consumption level of enterprises. By recording and analyzing electricity consumption data, enterprises can better grasp their energy consumption trends, formulate reasonable energy use plans, and achieve the goals of energy conservation and emission reduction.

[0035] The busbar joint monitor 22 is used to monitor the temperature information of the corresponding branch busbar plug-in box, and send the temperature information to the main controller 10 through the gateway. The temperature information includes the busbar duct temperature and the connector temperature, wherein the temperatures of the connector and the busbar duct have different correlations with the actual busbar temperature, and are also affected differently by the ambient temperature, that is, at different ambient temperatures, based on the same busbar temperature, the actual appearances of the busbar duct temperature and the connector temperature will be different, and the heat dissipation capacity of the connector and the busbar duct also has certain differences. Predicting the actual busbar temperature based on the temperature information of the two sampling points can effectively improve the prediction accuracy and reliability.

[0036] The main controller 10 also uploads the received power consumption information and temperature information to the background server 11, so as to obtain safety prevention information and fault alarm information through the analysis of the power consumption information and temperature information by the background server 11, wherein the collected temperature information includes the bus duct temperature and the connector temperature, and the temperature prediction results based on the temperature information obtained from different sampling media and sampling points can be mutually verified, thereby improving the accuracy and reliability of the actual bus temperature prediction.

[0037] To achieve safety precautions, in one embodiment, the backend server is further used to: obtain the operating power of the target branch bus plug-in box according to the power consumption information, obtain the predicted temperature information of the target branch bus plug-in box in combination with the temperature information of the target branch bus plug-in box, and provide safety precaution information according to the predicted temperature information. Safety precautions for each branch bus plug-in box can be performed separately.

[0038] In a specific example, temperature prediction includes: obtaining heating power according to the operating power of the target branch busbar plug-in box and the preset busbar configuration, obtaining heat dissipation power according to the busbar duct temperature and connector temperature of the target branch busbar plug-in box, and obtaining predicted temperature information according to heating power and heat dissipation power. Among them, the heat dissipation power is mainly obtained according to the real-time changes of the busbar duct temperature and the connector temperature, and the busbar configuration includes the surface area, length, cross-sectional area and resistivity of the material of the busbar, which needs to be confirmed according to the actual situation.

[0039] In order to improve the intelligence level of safety prevention, in one embodiment, the background server is also used to: record the historical information of the operating power, bus duct temperature, connector temperature and overheating faults of each branch busbar plug-in box, and obtain the overheating fault correlation coefficients of the operating power, bus duct temperature and connector temperature based on the historical information, so as to predict the overheating risk based on each overheating fault correlation coefficient and the real-time operating power, bus duct temperature and connector temperature of each branch busbar plug-in box, so as to issue an overheating risk alarm when there is an overheating risk based on the overheating risk prediction results.

[0040] Among them, the sum of the products of the real-time operating power, bus duct temperature and connector temperature of the branch busbar plug-in box and the corresponding overheating fault correlation coefficient is the overheating index. The overheating risk prediction result mainly includes the relationship between the overheating index and time, and the moment when the overheating index reaches the risk threshold is taken as the risk moment. Furthermore, the background server is also used to: issue an overheating risk alarm before the predicted overheating moment according to the overheating risk prediction result and the preset response time. That is, the moment obtained by subtracting the response time from the risk moment is the overheating risk alarm moment, so as to provide sufficient response time for the operator to control the main controller to close the corresponding branch busbar plug-in box to avoid the actual occurrence of overheating safety accidents.

[0041] Alarms are issued to remind manual processing, and manual re-inspection can be used to ensure the accuracy of emergency avoidance operations for overheating risks, to avoid direct power outages due to misjudgment, which would affect normal production.

[0042] The response time can be set based on the actual conditions of the factory or building, and can also be set based on the actual fault handling response capabilities of known safety incidents.

[0043] In a specific example, the backend server is also used to upload historical information to a cloud service platform, wherein the cloud service platform is used to expand the amount of sample data of overheating faults based on the historical information of multiple busbar plug-in box control systems, so as to obtain a remote overheating fault correlation coefficient based on the historical information of multiple busbar plug-in box control systems, and publish the remote overheating fault correlation coefficient to each backend server. Since the actual execution effect of the safety assurance work is objective, the fault data available based on a single busbar plug-in box control system is limited, and the big data service capabilities of the cloud service platform are fully utilized to effectively integrate data on various safety issues actually occurring in different regions, increase the number of samples of historical information on the operating power, bus duct temperature, connector temperature, and overheating faults of the busbar plug-in box, and thereby improve the accuracy of the obtained remote overheating fault correlation coefficient. The remote overheating fault correlation coefficient is distributed to the local backend servers of each busbar plug-in box control system, and the overheating fault correlation coefficient of the local backend server is updated, which can improve the accuracy of fault prediction.

[0044] The present invention also provides a busbar plug-in box control method, such as Figure 2 As shown, it specifically includes:

[0045] Step S01: monitor the power usage information of each branch busbar plug-in box, and send the monitored power usage information to the main controller through the gateway, wherein the power usage information includes current, voltage, harmonics, power and power consumption.

[0046] Step S02: Monitor the temperature information of each branch busbar plug-in box, and send the temperature information to the main controller through the gateway, wherein the temperature information includes the busbar duct temperature and the connector temperature.

[0047] Step S03: Control the opening and closing of each branch busbar plug-in box through the main controller, and upload the received power consumption information and temperature information to the background server, so as to obtain safety prevention information and fault alarm information through the background server's analysis of the power consumption information and the temperature information.

[0048] As a specific example, it also includes: recording the historical information of the operating power, bus duct temperature, connector temperature and overheating faults of each branch busbar plug-in box, and obtaining the overheating fault correlation coefficients of the operating power, bus duct temperature and connector temperature respectively according to the historical information, so as to predict the overheating risk according to each of the overheating fault correlation coefficients combined with the real-time operating power, bus duct temperature and connector temperature of each branch busbar plug-in box, so as to issue an overheating risk alarm when there is an overheating risk according to the overheating risk prediction results.

[0049] To improve the accuracy of risk management and control, the step of issuing an overheating risk alarm when there is an overheating risk according to the overheating risk prediction result includes: issuing the overheating risk alarm before the predicted overheating moment according to the overheating risk prediction result and the preset response time. Before overheating, the staff or workers in the power consumption area can be reminded to make accurate power outages, such as saving electronic files, etc., thereby reducing the impact of the suddenness of the system's automatic power outage on production when an overheating fault occurs.

[0050] In order to improve the prediction accuracy, it also includes: uploading the historical information to a cloud service platform, wherein the cloud service platform is used to expand the overheating fault sample data volume according to the historical information of multiple busbar plug-in box control systems, so as to obtain a remote overheating fault correlation coefficient according to the historical information of multiple busbar plug-in box control systems, and publish the remote overheating fault correlation coefficient to each of the backend servers.

[0051] The busbar plug-in box control system and method provided by the present invention are used for the centralized control of the building busbar plug-in box. The busbar plug-in box control system includes a main controller, and a power consumption monitor and a busbar joint monitor arranged in each branch busbar plug-in box of the building busbar plug-in box. The power consumption monitor and the busbar joint monitor send the monitored power consumption information and temperature information of the corresponding branch busbar plug-in box to the background server of the main controller through a gateway, so as to obtain safety prevention information and fault alarm information through the analysis of the power consumption information and temperature information by the background server. Safety forecasts can be made based on the power consumption information, bus duct temperature and connector temperature. The temperature collection points can be expanded to the bus duct, which can improve the temperature-based safety forecast capability and improve safety. The main controller can also remotely control the opening and closing of each branch busbar plug-in box, effectively improving the convenience of management and control.
