Smart Campus IoT Solution

In 2018, the Ministry of Education and the National Standards Committee successively issued policies and standards such as the "Education Informatization 2.0 Action Plan", the "Guidelines for the Construction of Digital Campus in Primary and Secondary Schools (Trial)", and the "Overall Framework for Smart Campus". Among them, the "Smart Campus Overall Framework" issued by the State Administration for Market Regulation and the National Standardization Administration of China has been officially implemented since January 1, 2019. The framework standard requires schools to achieve intelligent perception, intelligent control, and intelligent management.

3. Establish a conservation oriented smart campus and a safe smart campus, and work together to create a beautiful campus living environment in the new era.

Campus safety:Lack of security alerts for abnormal situations,Frequent safety accidents are difficult to prevent;

Campus energy conservation and environmental protection:Campus energy consumption is high, and there is a lack of unified electricity analysis and control, which requires response to energy-saving and emission reduction policies.

Campus management efficiency:There are numerous campus devices, making it difficult to achieve unified intelligent perception, control, and management.

In the construction process of IoT smart campus, we should clearly achieve the following goals:

1. Comprehensively enhance the safety level of campus, especially the safety level of campus fire protection.

2. ImplementationMore accurate energy consumption statistics and more convenient cost management.

3. Maintain compatibility and openness at the system level to facilitate the continuous informationization construction and transformation of the school.

4. Greatly reduce the overall deployment difficulty and cost of IoT smart campus solutions, shorten the overall installation cycle, and do not affect the daily teaching and management work of the school.

Through the LPWAN connection technology of the Wide Area Internet of Things, in the scenario of a smart campus, we can use a large number of different types of sensor terminals to build different specific business scenarios. include:

1Wireless sensor terminals for energy scenarios: light control switchesAir conditioning controller, smart meter, smart circuit breaker, etc.

2. Environmental ScenariosWireless sensor terminals: temperature and humidity monitors, air quality monitors, multifunctional weather stations, etc.

3. Fire sceneWireless sensor terminal:Smoke alarm, intelligent water pressure gauge, electrical fire alarm, etc.

4. Security sceneWireless sensor terminal:Wireless smart door lock, door magnetic sensor, water immersion monitor.

5. Networking equipment: G200LPWAN IoT gateway, G500LPWAN IoT gateway.

Through analysis and statistics of various types and dimensions of data, we canThe following five main scenarios are implemented on campus, including:

1. Campus Smart Classroom Solution

2. Monitoring solution for school computer rooms

3. Campus Smart Office Solution

4. Campus air quality monitoring solution

5. Campus fire safety monitoring solution

As shown in the figure, by intelligently managing lighting, air conditioning, and air quality, we aim to create a safe, energy-efficient, convenient, comfortable, and efficient learning environment for students. The campus smart classroom solution can achieve the following functions:

The smart classroom solution also supports subsystem expansion, including:

1.Curtain controller:Control the curtain situation according to the scene mode, and open and close the curtain with one click.

2. Intelligent circuit breaker: occurrenceAutomatic tripping in case of short circuit overload; It is also possible to remotely control the unified shutdown of power lines to achieve energy conservation.

In the process of campus management, the office environment of teachers is also very important. Through LPWAN IoT technology, a multi-sensor fusion smart office solution is created to enhance campus office comfort. including:

1. PM2.5 detection, temperature, humidity, TVOC monitoring and control, real-time adjustment of room environment control equipment;

Combining advanced IoT technology with traditional natural science knowledge in the context of the era, students will learn to monitor the changes in plant growth and understand meteorological and soil indicators. Inspire students' desire to explore and improve their ability to discover and solve problems.

In the campus fire safety monitoring plan, we can use various devices to meet the fire monitoring needs in different scenarios:

1. Smoke alarm, which alarms when fire smoke is detected, can be used in classrooms, computer rooms, conference rooms, etc.

1. Make the campus safer: When a malfunction occurs, be aware of and handle it immediately,The monitoring of electricity, fire protection, access control, environment and other aspects will be transformed from a passive mode of "post disposal" to an active mode of "pre prediction", with early warning of safety hazards and corresponding protective measures activated to ensure campus safety.

2. More energy-efficient and cost-effective: Managing campus lighting and air conditioning to save energy, a single air conditioning device can save 158 yuan in electricity bills per year (1100W (1.5P) * 20% * 8h * 180 days * 0.5 yuan/kWh=158 yuan).

3. Make management more efficient: make work smarter, and "turn N into 1" campus management: one system, take care of everything. Integrate energy, fire, and safety management systems, connect all devices to the internet, and achieve intelligent monitoring.

4. Unified management: Unified management of all schools within the designated area, closely following the requirements of the new infrastructure and information technology construction environment.

5. Enhance students' sense of immersion: Combine advanced IoT applications with knowledge to create immersive experiences and learning.

Shanghai Huishi Primary School Project:

Including smart classrooms, lighting renovation, electrical safety monitoring, dynamic environment supervision of computer rooms, smart door locks, etc.

Project of Chibi No.1 Middle School:

Schools need to install air conditioning in classrooms and dormitories, use IoT devices for unified management of air conditioning, achieve energy consumption statistics and batch control functions, strengthen energy-saving of classroom and dormitory air conditioning, reduce energy waste, and respond to national energy conservation and emission reduction policies.
