Embodiment 1
[0029] see figure 1 , a network positioning system based on BLE technology, characterized in that, comprising:
[0030] Multiple BLE nodes, install a BLE Bluetooth module on each street lamp on the side of the road, each BLE Bluetooth module is a BLE node; each BLE node can receive surrounding broadcast signals, and each BLE node can communicate with multiple BLE nodes around The node keeps connected and obtains the broadcast information of the surrounding BLE nodes in real time as the source of the signal; each BLE Bluetooth module can be electrically connected to the street lamp, so as to use the power grid of the street lamp for power supply, or install solar panels on the street lamp to supply power for the BLE Bluetooth module.
[0031] Multiple BLE routing gateways are installed in several places that can be connected to the Internet, as the Ethernet entrance, and each BLE node reaches the Ethernet entrance through a link composed of multiple BLE nodes around it to link ...
Embodiment 2
[0040] see figure 2 , a positioning method based on the BLE technology-based networking positioning system described in Embodiment 1, characterized in that: comprising the following steps:
[0041] S1. Each BLE node monitors whether there is a broadcast signal sent by the user around. If there is, go to step S2. If not, continue to step S1. That is, the user on the road can send out a broadcast signal when needed. For example, when the vehicle has an accident, the user can Send out a distress broadcast signal;
[0042] S2. The BLE node that monitors and discovers the broadcast signal sent by the user transmits the broadcast signal sent by the user and its own location information to the BLE routing gateway, that is, the nearest BLE Bluetooth module of the accident vehicle, according to the link in the routing table stored in the BLE Bluetooth module. After monitoring the distress signal, the BLE node transmits its own position and the distress information sent by the acciden...
