Description
Technical Field
The invention relates to the technical field of intelligent automobiles, in particular to an equipment matching method for Bluetooth positioning.
Background
The conventional BLE-PEPS (Bluetooth low energy-keyless start system) comprises a main node and an auxiliary node with different numbers.
The common method for acquiring the RSSI (received Signal Strength indication) of the BLE-PEPS system comprises the following two methods:
(1) the RSSI measurement of the connection channel between the intelligent device (such as a smart phone, a smart bracelet, a smart watch and the like) and the main node and the RSSI measurement of the connection channel between the intelligent device and the auxiliary node are combined together to obtain the RSSI measurement value of the main node and the auxiliary node, and the RSSI measurement value is used for positioning the intelligent device. In this way, since the smart device needs to be connected to multiple nodes on the vehicle at the same time, when the number of bluetooth nodes on the vehicle is large (greater than 3), the smart device cannot be stably connected to multiple modules on the vehicle at the same time, and thus the usage of the scheme is limited.
(2) The RSSI measurement of the connection channel between the intelligent equipment and the main node and the RSSI measurement of the broadcast sent by the intelligent equipment by the auxiliary node are combined together to obtain the RSSI measurement value of the main node and the auxiliary node for positioning the intelligent equipment. The key point of this scheme is that the secondary node can successfully filter out the broadcasts of the connected intelligent devices. However, during normal use, the following problems are encountered: the smart device may shield the broadcast content in some scenarios (e.g., turning off the screen), so that the secondary node cannot filter the broadcast of the smart device through the broadcast content, which results in that when the secondary node wants to identify the broadcast of the smart device, information such as an Identity decoding Key (IRK) of the smart device must be obtained to resolve a Media Access Control Address (MAC) of the broadcast of the smart device, so as to implement filtering of the broadcast. Therefore, the master node must pair with the smart device to acquire the IRK. In the conventional pairing, part of pairing information is deleted when the main node pairing information is full, so that the main node and the intelligent device with the deleted pairing information cannot realize pairing information synchronization, and further normal communication and positioning cannot be performed.
