[0064] Such as figure 1 As shown, it is a specific flowchart of a crowd interaction situational awareness method for primary and secondary schools in the present invention. it includes:
[0065] S1: Establish a wearable terminal for primary and middle school students to wear, establish a first frequency point for the wearable terminal for mutual communication between the wearable terminals, and establish a second frequency point for the wearable terminal Communication between the terminal and the area reader / writer, wherein the area reader / writer is a device set in each area for data interaction with the wearable terminal.
[0066] Specifically, in this embodiment, since the main application objects of the present invention are primary and middle school students who cannot carry their mobile phones to school during class, it is first necessary to establish a terminal that is easy for primary and middle school students to carry and does not have too many functions. carry.

[0089] This embodiment provides a specific embodiment of a crowd interaction situational awareness method for primary and secondary schools of the present invention, specifically:
[0090] Taking school A as an example, students are equipped with 4G card machines as wearable terminals. The 4G card machines have GPS / BD positioning (outside school) and 2.4GHz positioning (in school). The first frequency point is 2.4GHz, which is used for wearable terminals Inter-communication between campuses to achieve information convergence in the school, and a second frequency point of 125KMHz is established for communication between wearable terminals and regional readers to realize situational awareness of students in the school. The card machine ID is a 4-byte long integer, and the broadcast short packet (P S ) is in the specific format: type code (1 byte) + machine ID (4 bytes) + Checksum (1 byte), unit duration (T u ): It is the duration of broadcasting short packets (different MCUs, m...
