With the acceleration of smart city construction and the state's emphasis on education, smart campuses and smart classrooms will be built in cities one after another, focusing on solving various practical problems in traditional campus and classroom management.
Common conditions and problems in campus and classroom management
In the past, there were often the following problems in campus management and classroom equipment use:
(1) There were so many equipments that it was difficult to realize intelligent perception and control management;
(2) It is too complicated to manually push down the projection curtain, switch on and off the lights, adjust the temperature of the air conditioner and switch on and off the exhaust fan, which not only wastes the actual teaching time, but also greatly reduces the classroom experience;
(3) There is no clear data to check and analyze the usage and energy consumption of all kinds of equipment, which is not conducive to energy saving and improvement.
according to the actual needs of classroom scenes, Shunzhou Intelligent has launched an Internet of Things scheme for smart classrooms, and is committed to realizing the intelligent upgrade of classroom scenes.
Smart Classroom Internet of Things Scheme
Based on the advantages of Zigbee technology, Shunzhou Intelligence, with Zigbee3. gateway and embedded Zigbee module, can realize intelligent control of electrical equipment such as lighting, fans, air conditioners, curtains, audio-visual teaching equipment and smart door locks in classroom scenes, save personnel management costs, improve equipment management efficiency, and create an intelligent teaching/learning experience for teachers and students.
1. Scenario mode
Scenario strategy is a set of actions, which is simple and efficient to operate. If you start a day's study period in the morning, the air conditioner and exhaust fan will be automatically turned on in advance to improve the air environment in the classroom; When students enter the classroom, the entrance guard is opened and the music is played; When the teacher is in class, the projection is turned on, the projection curtain is lowered, and the podium lights are turned off or dimmed. Through the scene switch and system configuration, enter the preset scene mode with one button. Such as "class scene", "class scene", "multimedia scene" and "audio-visual scene", can be customized.
2. Intelligent access control system
Intelligent access control supports administrators to conveniently enter personnel access records and master access control status and alarm information in real time. In addition, the intelligent access control system combined with face recognition function effectively ensures the security and safety of school classrooms.
3. Classroom equipment management system
Real-time status display of equipment: equipment working status (such as whether the lights are on or off) and equipment fault display (whether the switch is faulty or not) can be displayed online in real time. Independent control function of equipment: each equipment can be controlled and managed through the equipment management system. The controlled equipment includes: air conditioner, projection controller, computer, fluorescent lamp, curtain, energy and environmental equipment, professional equipment, access control and door lock, etc.
4. Intelligent environment monitoring system
Classroom environment monitoring and adjustment. Real-time monitoring of classroom temperature and humidity and air quality can be realized through temperature and humidity sensors and air quality sensors, and environmental data can be transmitted back to the server and cloud platform in real time. Through strategic deployment and equipment linkage, fresh air, humidifiers, fans and other equipment can be turned on to adjust the classroom environment. Realize the intelligent control of classroom environment and ensure that the teaching environment is in a comfortable state.
5. Smart energy-saving system
Through the Internet of Things platform, classroom equipment can be remotely controlled and switched on and off, and the scene mode can be set, and the equipment can be turned on and off in a self-defined time period to avoid long-term turning-on and idling of equipment during non-teaching time. At the same time, the platform can display and analyze energy consumption data, clearly understand the electricity consumption of various regions and types of equipment, and realize energy conservation and emission reduction.
6. Smart electricity safety system
The intelligent switch, smart plug and temperature control panel in the classroom are embedded in Zigbee module, which can remotely query the electricity consumption data of air switch line voltage, leakage current, line power, line current and switch status, and set up automatic detection of leakage protection function, remote centralized control management of all electricity line switches in the area, and free grouping and setting of timing switches.
advantages of the smart classroom IOT scheme
1. Wide equipment coverage and convenient deployment
It supports most manageable equipment in the classroom, including dozens of IOT sensors and controllers such as multimedia, air conditioners, switches, energy-efficient sockets, lights, curtains, environmental monitoring, security and electricity. The scheme adopts ZigBee wireless fidelity, which avoids the traditional wiring problem, and can quickly complete the deployment of the hardware environment of the Internet of Things through simple upgrading, which reduces the hardware deployment cost and construction difficulty and greatly speeds up the deployment.
2. Intelligent and convenient use
The scene and timing strategy of the Internet of Things can be flexibly customized to realize automatic control of equipment in batch and timing. Intelligent automatic adjustment can be realized according to temperature and humidity and light intensity.
3. Energy saving and emission reduction
Detect the power consumption of key energy-consuming equipment in real time, realize the transparency of energy consumption information and realize the scientific management of energy consumption.
