1. Industry background
Electrical fire generally refers to the fire caused by the release of heat energy after the failure of electrical lines, electrical equipment and power supply and distribution equipment, resulting in the ignition of the body or other combustibles under the conditions of combustion .
In recent years, with the increase in the use of high-power electrical appliances and the aging of lines year by year, electrical fires in our country have occurred frequently, causing heavy casualties and property losses. Fires caused by electrical failures account for more than 30% of the total national fires, of which Heavy and heavy electrical fires account for 70% of the total. In order to effectively curb the high momentum of electrical fires and ensure the safety of people's lives and property, various national ministries and governments have issued documents to carry out electrical fire management work.
In recent years, with the continuous development of wireless communication technology, an electric power safety supervision service system that uses advanced technologies such as the Internet of Things, cloud computing, and big data to detect the hidden dangers of electric lines and electric equipment in real time has emerged at the historic moment.
Second, the solution
Based on modern information technologies such as IoT sensing, mobile internet, cloud computing technology and big data, the electricity safety monitoring service system is composed of intelligent sensing terminals, wireless transmission equipment, and electricity safety monitoring service platforms. The data (cable temperature, current, residual current, fault arc) is monitored in real time, and the data is transmitted to the power safety monitoring service platform through wireless communication.
Three, program advantages
(1) Data visualization display
The electricity safety supervision service platform stores, processes, and analyzes the power supply side and electricity measurement and electricity parameters collected by the electricity-aware terminal, and displays them dynamically in the form of configuration and large screen. Users can know the safety situation of enterprise electricity consumption in real time through the mobile phone App or Web client anytime, anywhere.
Insight
The electricity safety supervision service platform performs statistical analysis on parameters such as voltage, current, power supply quality (three-phase unbalance, power supply quality qualification rate, power failure, etc.), leakage current, cable temperature, load current, electrical energy, and fault arc, And compare with the electrical fault characteristics, timely grasp the hidden power safety hazards of the dynamic operation of the line, prevent fires, and improve the enterprise's power safety management level.
(2) Intelligent alarm
The monitoring data can be set according to the site conditions. Once an abnormal limit is exceeded, the on-site alarm sounds and lights alarms. The integrated management platform sends alarm prompts to the mobile phone APP and Web client, and informs the relevant by SMS and voice. principal.
Intelligent monitoring
The reliability of user's electricity consumption is very important. In order to avoid false alarms caused by the system, the system adopts the monitoring method of "civil air defense + technical defense". The duty personnel can confirm that there are hidden dangers in the line through multi-factor analysis. Remotely control the power off of related lines, and control the influence of power off to a lesser extent.
(3) Energy consumption statistics
Calculate the power consumption of each monitoring line and display it in the form of a graph or table to facilitate users to check the energy consumption at any time. The report can be exported.
(4) Someone's cloud electricity safety monitoring service platform
4. Industry Application
The electricity safety monitoring service system can effectively solve the problems of line aging, no professional electrician investigation, and no real-time supervision in various personnel-intensive places. It can find hidden dangers in advance and truly guarantee the safety of electricity use. The system can be deployed in factories and mines, chemical enterprises, shopping malls, hospitals, schools, hotels, residential areas and other places AC low-voltage power distribution system.
