Updated into wireless downloading.
If CC2530 chips 1 detect that surrounding enviroment do not meet the environment shown in Fig. 1, can extend dormancy time to
Reduce power consumption.If in a network, do not moved, closing network function can be constantly in and carry out either shallow resting state.
If attitude transducer 2 do not detect for a long time it is any rock, network function can be opened and notify administrative staff, meeting simultaneously
Flash LED light 4.
The utility model is new using the design such as wireless sensing location technology, photovoltaic power generation technology, wireless download technology
Electronic school badges, the Electronic school badges worn by the reference mode set in the school to every student position, and will be substantial amounts of
Student data uploads on the cloud platform server of supervision center in real time, carries out big data analysis.
Electronic school badges position self-position by ZigBee RSSI intensity levels, while steady using test pose sensor 2
Determine RSSI positioning result.The inertial data that Electronic school badges provide according to test pose sensor 2, when it detects that Electronic school badges
Location frequency is reduced when not moving, and then reduces the overall power of Electronic school badges.
Obviously, the Electronic school badges can reduce difficulty of the middle and primary schools to student-directed, coordinate other security systems, can show
The reduction middle and primary schools safety hazards of work, therefore the system has very high promotional value.
In addition to the implementation, the utility model can also be all to use equivalent substitution or equivalent by other embodiment
The technical scheme formed is converted, is all fallen within the protection domain of the utility model claims.
