Product DescriptionTechnical ParametersFunctional Features
With the deepening of education informatization construction, more and more digital networks have entered all aspects of campus teaching, life and management. Traditional analog campus broadcasting tends to fall behind and be eliminated in terms of application modes and supporting functions. It is far from meeting the needs of modern campus digitization and network construction. The school dormitory wireless intelligent management system uses kilometer-level wireless audio technology to integrate IoT technology, focusing on solving the problems faced in campus dormitory management:
1. After the lights are turned off, there are still loud noises in the student dormitory, which seriously affects the rest of the students in the same dormitory and the surrounding dormitories, and thus affects the study of the next day. The school invests a lot of manpower in daily inspections, but it still cannot solve the dilemma.
2. After the dormitory is closed for management, the daily management of the dormitory management, such as express delivery, take-out delivery, and notification delivery, must be carried out on a daily basis. The problem of not being able to notify in time needs to be resolved urgently.

1. In each dormitory area, an audio probe is installed every 10 meters. When the audio probe detects that the on-site sound is higher than 80 decibels or the set decibel volume, it will alarm. The guard can make a decision based on the on-site sound returned by the audio probe. Broadcast a warning or rush to the scene to deal with it. 2. The background collects the signals returned by the sound collectors in each dormitory. Once the set threshold is exceeded, the background will send an alarm command and the small speaker of the dormitory noise tester will alarm; 3. Relevant announcements from the Education Bureau, schools, and dormitory management can be broadcast through the small speakers in the dormitory, and the power of the speakers is set at about 3W. 4. The background collects relevant noise data, analyzes statistics, and visualizes charts for managers' reference and judgment. 5. The background can be set to manage broadcast rights. Different rights have different management methods and ranges of rights. Each right has a dedicated account and password.
