RFID+Bluetooth smart bracelet enters the 2.0 era
[Copy link]
With the advancement of education and college entrance examination reform, provinces have gradually implemented mobile class scheduling. The new teaching method has brought new challenges to students, school management and home-school interaction. Students have more opportunities for supervision loopholes, parents have more worries and anxieties, and teachers and administrators have greater workloads and responsibilities.
At present, most software systems need to rely on people to collect information and input. At the same time, students lack a practical information terminal, and the data only stays between parents and teachers. With the continuous promotion and development of education reform, student bracelets are becoming an indispensable part of campus information construction because of their advantages such as no entertainment, easy to wear, long standby time, complete replacement of student cards, and moderate price.
There are two technical solutions for smart student bracelets on the market now, Bluetooth only and RFID+Bluetooth. As first-generation solutions, they both have some inherent defects. With the deepening of application pilots and the gradual maturity of technical solutions, Art IoT (Shenzhen Art IoT Technology Co., Ltd.) launched the second-generation smart Bluetooth student bracelet overall solution. From the top-level architecture to business applications, it is deeply customized for campus applications. Once launched, it has been recognized by customers and gradually replaced the early first-generation products in the market.
The following is a comparison of the technical differences between the second-generation single Bluetooth solution and the RFID+Bluetooth solution:
From the comparison, we can see that the overall solution of the second-generation smart Bluetooth student bracelet is already in the leading position in the industry;
Below we introduce the advantages and new features of the second-generation smart Bluetooth student bracelet solution:
Higher attendance rate:
Traditional campus attendance mainly relies on hardware. If a single piece of hardware fails, the corresponding attendance will fail. For example, if the equipment responsible for attendance at the school gate fails, the attendance of the entire school will fail.
The second-generation smart Bluetooth student bracelet solution uses a hardware + software algorithm approach. If a single hardware fails, attendance data will still be generated. For example, if the equipment at the school gate fails, the software will use the student's location data at school to determine and generate student attendance records.
Higher precision positioning:
The core of high-precision positioning is to meet the needs of walking attendance. Previous product solutions were unable to locate and distinguish which classroom the students were in, so the software used "fuzzy" processing. For example, if a student was located in classroom A and classroom B at the same time, the software would judge the attendance as successful based on the class schedule if either classroom A or classroom B was correct. What's more, due to device signal drift, students outside the classroom may also be located in the classroom, resulting in incorrect attendance.
The second-generation solution does not rely on signal coverage for positioning, eliminating the system's dependence on device performance or device installation location, and improves the original positioning accuracy from 10 meters to 30 meters to 1 meter to 5 meters. All positioning and classroom attendance are real data.
Full remote management of online devices:
Previously, online management mainly involved checking the entered device information and whether the device was online. The optimized hardware devices will report more operating status information (such as software version number) and key data (such as bracelet power information), provide alarm reminders for abnormal situations, and enable remote one-click upgrades of fixed devices. This is especially useful for customers on multiple campuses, and saves a lot of manpower costs compared to the method of dismantling the device for hard-wired upgrades.
Parents do not need to install APP:
Some functions of the previous solution required parents to install the APP and connect the bracelet to operate, which increased the cost of use for parents and schools in disguise and provided a poor user experience.
The second-generation smart Bluetooth student bracelet solution can realize functions that require APP implementation, such as calibrating the bracelet time and upgrading the bracelet firmware, which can be achieved automatically or remotely with one-click control.
New healthy campus features:
Many schools now have air conditioners installed, but the adjustment of the air conditioners has not been centrally automated and controlled. The control of the equipment is quite arbitrary, and parents are worried. The second-generation equipment can monitor the temperature and humidity outside and inside each classroom in real time. These data are provided to the school as management input and displayed to parents on mobile devices.
Added Auto-Recover automatic recovery function:
When the device encounters network problems and partial system failures, the system can perform self-repair operations without human intervention. When the repair fails, it can also automatically restart to automatically ensure the stable operation of the system.
New 4G extension function:
Most schools have network reliability issues. Frequent network outages will cause interruptions to the smart campus system services. In this case, a 4G module can be added to the device to transmit data back through the operator network to ensure the continuity and stability of the system.
Improve POE compatibility:
There are two types of POE switches on the market: standard and non-standard. In order to adapt to the POE switches of all schools, the hardware equipment has been designed to be fully compatible with all standards.
