Campus dormitory electricity monitoring system based on NB-IOT communication and control method thereof

Abstract

The invention relates to a campus dormitory electricity monitoring system based on NB-IOT communication and a control method thereof. The system includes an electric detection module, an electric circuit break module, an infrared temperature monitoring module, a smoke sensing module, a wireless communication module, a main controller and a monitoring center, wherein the electric detection module and the electric circuit break module employs integrated design, the electric detection module and the power circuit break module respectively achieve signal feedback with the main controller, the infrared temperature monitoring module and the main controller have signal feedback, the main controller sends a command to the electric circuit break module to control on / off according to a human body infrared signal and the duration, a student dormitory is monitored and controlled under the weak electricity environment, the human body pyrolysis infrared technology is adopted to detect people existence in the dormitory, for example, indoor monitoring systems monitor safety of electricity, if no one is in the dormitory, the dormitory is directly powered off, and the risk of fire caused by chargingmicro-power products such as mobile phones and laptops when no one in the dormitory can be eliminated.

Description

technical field [0001] The invention relates to the technical field of campus dormitory electricity management, in particular to a campus dormitory electricity monitoring system and control method based on NB-IOT communication. Background technique [0002] The school is a place with a large flow of people, and each dormitory is a small group. School dormitories are basically multi-person dormitories. Because students have little life experience, they often cannot be cautious enough in dormitory safety. At present, in major colleges and universities, there will basically be a short circuit of the wires caused by the transition of electricity, and at least the dormitory will be broken. If the electricity is too heavy, it will cause a fire and cause the safety of life and property. In the prior art, electricity monitoring for campus dormitories has also been applied. For example, Patent No. CN202093352U discloses a safety monitoring and alarm system for electricity use in sch...

Problems solved by technology

However, with the development of technology and information technology, students use mobile phones, PDAs, laptops and other small electrical equipment more and more frequently, which leads to the need to charge mobile phones, PDAs or computers when students leave the dormitory. The current during charging is very small, and the original overcurrent or overload monitoring system does not work at all. Fires caused by charging mobile phones or notebooks in student dormitories occur from time to time, which brings great harm to the safety management of the school and the lives of students. Great hidden danger. After the fall of 2018, colleges and universities in the applicant's area had two campus fire accidents due to students charging mobile phones in the dormitory during class. Therefore, fire accidents caused by weak electricity in campus dormitories are on the rise year by year, especially for teenagers. Students love mobile terminal devices such as mobile phones and notebooks. Every dormitory has mobile phones or notebooks that are charged at any time when there is no one in the dormitory. It is urgent to prevent fire accidents caused by weak electricity in campus dormitories.
