As everyone knows, students are the flowers of the motherland and the talents of the future.Nowadays, more and more schools have established a school bus to pick up and drop off students to go to school.However, school bus safety accidents occur frequently.
For example,unqualified school bus driver failed to work with working license;collision accident;after the school bus stops, the students are forgotten on the school bus. The high temperature and lack of oxygen cause the child to suffocate; and so on.These accidents have had a huge negative impact on society and caused irreparable injuries to the students' families.

 

Therefore, how to strengthen supervision through technical means, prevent accidents, and promptly carry out rescue and emergency treatment in the event of a crisis, so as to minimize the occurrence of accidents, the current government, schools, and enterprises should actively respond to their obligations.

Our company combines years of technical precipitation and project experience accumulation,a school bus mobile video surveillance solution based on 4G network, RFID tag, video population statistics, temperature sensing, audio and video, storage, GPS and other technical means is proposed, in order to improve the safety and reliability of school bus driving. Our this kind solution is widely used in school bus monitoring projects at home and abroad.

Overall design

As following picture shows: this project utilizes audio and video codec, 4G wireless network, GPS\GIS system, temperature sensor, demographics, alarm and inspection button, using vehicle terminals to complete business logic design, real-time, centralized and intuitive monitoring and dispatching of mobile school bus vehicles by the monitoring center.en.citops.com
