The electricity safety module conducts uninterrupted data tracking and statistical analysis on the main factors of electrical fire (cable temperature, leakage current, load current, voltage), collects on-site data through 4G. The potential safety hazards of electrical lines and electrical equipment (such as abnormal cable temperature, overload, overvoltage, undervoltage and leakage, etc.) and timely warning through SMS, APP push, automatic voice calls, etc., to effectively prevent the occurrence of electrical fires. The system can display electrical parameters such as leakage current and cable temperature at all monitoring points, support inspection records and dispatching operations, provide potential safety hazard analysis reports, and evaluate enterprise electricity safety status in real time.
3.2.2 Power Quality
The issue of power quality has attracted more and more attention and has become one of the research hotspots of the power system. On the one hand, with the development of science and technology and the wide application of various sophisticated and complex electrical equipment, most of these equipment are very sensitive to power quality; As a result, the power quality becomes very unstable. The main purpose of power quality analysis is to determine the type and range of power signal disturbances, and to effectively adjust and compensate for the corresponding disturbance sources. Therefore, the key to improving the power quality is to obtain the information of various disturbance signal sources timely and accurately.
Power quality monitoring includes three-phase unbalance, harmonics and power factor. When the three phases are unbalanced or the power factor is too low, an alarm will be generated, and be notified to users by APP push, SMS, email and so on.

3.3.1 Smart Lighting
With the continuous improvement of people's living standards, people's requirements for working and living environment are getting higher and higher, and the requirements for lighting systems are also getting higher and higher. The energy consumption in the lighting field accounts for a considerable proportion of the total energy consumption, and saving energy and improving lighting quality are the top priorities. As an important part of electricity consumption, lighting electricity has accounted for about 10% of electricity consumption. With the rapid development of my country's national economy and the continuous improvement of people's living standards, lighting electricity consumption will continue to increase.
Smart lighting uses the Internet of Things technology to continuously monitor the power consumption status of lighting circuits installed in various areas of the city. The platform judges the working condition of the lamps by monitoring the current and voltage value of the lighting circuit. Any abnormal working state can be monitored by the platform, and the warning and alarm information can be pushed through the mobile APP, SMS, and email, quickly reach the person in charge, remind the operator that the contactor trips, the power supply loses voltage, etc.

However, news of safety and fire accidents related to electric bicycles are also frequent, and there is a trend of increasing year by year. It has brought great losses to the society and has become a hidden danger to the safety of people's lives and properties. Based on the hazards and characteristics of electric bicycle fires, government departments at all levels have issued documents to regulate the parking and charging behaviors of electric bicycle fires. The charging operation function module of the car/battery car continuously collects and monitors the data of the charging pile site and each charging pile connected to the system through the Internet of Things technology, and at the same time protects against various faults such as over-temperature protection of the charger and over-voltage of the input and output of the charger, undervoltage, insulation detection failure and a series of faults for early warning. After the user scans the QR code through the APP, the system initiates a charging request and controls the charging pile corresponding to the QR code to complete the charging process of the electric vehicle. The charging pile can be equipped with wireless module to connect to the Internet, cooperate with encryption technology and key distribution technology, and directly connect with the cloud based on the data exchange protocol based on TCP/IP.
3.4. energy analysis
3.4.1 energy management
In order to steadily advance the dual carbon goal, under the background of "dual control" of energy consumption intensity and total consumption, enterprises need to consider how to deal with the dual control of energy consumption to ensure normal production. Most of the existing enterprises still use the "individual planning, independent design, independent operation" mode of various energy supply systems such as electricity, water, gas, cooling, and heat. Insufficient measurement equipment is generally detected; the measurement accuracy of measurement equipment is not high and the measurement data is inaccurate; the reliability of manual meter reading is low; it is difficult to effectively monitor and evaluate the energy efficiency of major energy-consuming equipment; Provide reliable reference data; lack an effective enterprise energy efficiency evaluation index system, and it is difficult to implement energy consumption management measures.
The energy management module adopts automation and information technology to realize the automatic and scientific management of the whole process from energy data collection, process monitoring, energy medium consumption analysis, energy consumption management, etc. Therefore it organically combines the whole process of energy management, energy production and use, and uses advanced data processing and analysis technology to conduct offline production analysis and management, to achieve unified scheduling of the entire plant's energy system, and to optimize energy medium balance and effective use. And it also improves energy quality, reduces energy consumption, and achieves the purpose of saving energy and reducing consumption and improving the overall energy management level.
3.4.2 Value-added services
（1）Industrial configuration
The traditional industrial automation configuration application development method requires developers to have the ability to write code, understand the concepts and use methods of related development frameworks. And this development method needs a long development cycle and very high requirements for developers. At the same time, the traditional industrial automation configuration applications are deployed in the industrial field, and the deployment convenience and accessibility are very low.
With the rapid development of the Industrial Internet, application requirements are often updated and iterated very quickly, and equipment manufacturers often do not have the relevant industrial configuration software development background, which makes the development and update speed of industrial configuration software very slow, often unable to meet the needs of rapid business growth. At the same time, the access to the industrial configuration software is no longer limited to the industrial site, and the demand for access from outside the industrial site is also increasing.
The industrial configuration module in the IoT EMS platform solves the problems of low deployment and low accessibility of traditional industrial automation configuration applications. Users can adjust the configuration screen components by dragging and dropping the mouse in the development tool. attribute, location, size, etc., and built-in rich configuration component library, so that users do not need code writing ability, no technical background of industrial automation configuration software development, but also can easily develop industrial configuration interface, and also support data Display, remote control and other functions.
