The international student apartment of a vocational and technical school in Jiangsu has gradually exposed problems such as aging lines and insufficient electricity load due to its long construction period. In recent years, with the continuous expansion of the scale of international students in schools, the usage density of various electrical appliances such as computers, air conditioners, and electric heaters has greatly increased. Unsafe electricity use behaviors such as unauthorized wiring and illegal use of high-power equipment have occurred from time to time. This not only easily leads to electrical fires, but also directly threatens the personal and property safety of international students, and brings huge challenges to the logistics safety management of schools.

In the apartment renovation project, the school has introduced the "Electricity Security Guard" intelligent safety electricity protection device from Li'an Technology, aiming to fundamentally solve the problem of electricity safety, achieve the intrinsic safety of "electricity does not ignite, electricity does not harm people, and electricity does not leak" electricity, and create a worry free living environment for international students.

　　

The core of the "An Dian Guard" intelligent safety electricity protection device lies in its reliance on Dianyi Cloud, which innovatively adopts isolation and stable current technology and instantaneous arc extinguishing technology, and can provide all-weather protection, monitoring, and control of power supply lines.

01. Eliminate electrical fires and achieve the principle of 'electricity does not ignite'

In response to the core pain points of aging apartment lines and frequent use of electrical appliances that can easily generate electrical sparks, the device continuously monitors key electrical parameters such as current, voltage, and cable temperature in the lines in real-time. Through intelligent algorithms, it accurately identifies various fire hazards such as overcurrent, overload, and poor contact. Once abnormal parameters are detected, the system will immediately activate the warning mechanism to block the path of fire occurrence in advance and eliminate the risk of electrical fires from the root.

02. Upgrade electric shock protection to achieve "no harm caused by electricity"

When detecting human electric shock or circuit leakage, a special protection mechanism will be activated within milliseconds to quickly limit the leakage current to a safe range, ensuring that the electrocuted person is not harmed. At the same time, the device adopts precise identification technology to avoid false tripping caused by slight leakage of electricity in the circuit, ensuring that electricity consumption in other areas is not affected.

03. Full time monitoring and warning to achieve "no electrical leakage"

24/7 monitoring of the insulation status of power lines and equipment leakage. Once insulation damage or electrical equipment leakage is detected, the system software will immediately use multiple alarm methods (big data management platform pop-up, management personnel mobile app push, SMS reminder, phone notification) to synchronously push alarm information, ensuring that operation and maintenance personnel are aware of the location and specific situation of the hidden danger at the first time, and can quickly come to the site for disposal, blocking the spread of leakage risk from the source.

04. Stable power supply guarantee, adhere to the principle of "uninterrupted power supply"

International student apartments need to meet the 24-hour study and living electricity demand. Frequent power outages can seriously affect the living experience and learning efficiency of international students. The 'Security Guard' can accurately distinguish between normal electricity fluctuations and real fault risks, effectively avoiding unnecessary tripping caused by minor abnormalities. Even if safety hazards are detected in local circuits, precise control is only carried out on faulty circuits, without affecting the normal power supply of other circuits, achieving a dual guarantee of "safety protection and continuous power supply", making it more reassuring and convenient for international students to use electricity.

The intelligent electricity management software that comes with the product provides comprehensive digital support for apartment electricity management. Management personnel can monitor the load operation status of each room in real time through the monitoring platform of computer WEB and mobile APP, accurately identify various abnormal faults such as overvoltage, undervoltage, and illegal high-power electricity use, and all abnormal information is synchronized and alarmed in real time, truly achieving "early identification and disposal of faults"; At the same time, the platform supports remote control of load switch on/off function. If students are found to be using high-power appliances in violation of regulations, management personnel can remotely cut off the power supply of the room and send alarm notifications through the platform without on-site inspection, efficiently regulating electricity usage behavior and significantly reducing management costs.

The "An Dian Guard" intelligent safety electricity protection device has demonstrated strong scene adaptability and practical value in the renovation project of an international student apartment in a vocational and technical school in Jiangsu Province, with multiple core functions such as no harm caused by electric shock, no fire caused by electricity consumption, stable and uninterrupted power supply, comprehensive no leakage, early fault recognition, and full scene intelligent control. After the renovation, the detection rate of electrical hazards in the apartment has significantly increased to 99%. Previously difficult to detect issues such as line aging and hidden leakage can be accurately identified and quickly dealt with, completely solving the long-term problem of electricity safety management faced by the school.
