In this embodiment, the positioning module may be a positioning management system in a station of a gas station, an edge calculation module, or a positioning module of a smart refueling platform. When the positioning module is a station positioning management system (for example, a computer of a gas station) or an edge calculation module of the gas station, the positioning module is connected with the bluetooth receiver and is used for acquiring the bluetooth signal received by the bluetooth receiver and acquiring positioning information based on the bluetooth AoA technology.

The traditional Bluetooth positioning is that the distance between a Bluetooth tag and a positioner is determined according to the Bluetooth signal strength (RSSI), and the coordinates of an object are finally determined by utilizing a triangulation positioning algorithm through a plurality of positioners; the biggest problem of estimating the distance based on the RSSI is that the bluetooth 2.4GHZ high frequency signal is greatly interfered. In addition to various indoor reflection and refraction, the RSSI value obtained by the locator has no great reference value; meanwhile, in order to improve the positioning accuracy, the RSSI value has to be acquired several times to smooth the result, which means the increase of the time delay.
In the Bluetooth positioner, the double antennas are arranged, the distance between the two antennas is d, the time for the same signal to reach the two antennas is different, and the phase loops of the signal are also different; and calculating the relative angle of the object and the locator according to the phase difference, and finally calculating the distance and the coordinates of the object according to the relative angle and the antenna distance d. Unlike the traditional bluetooth positioning based on the calculated signal strength (RSSI), the bluetooth AoA calculates the distance according to the time difference (phase difference) of the same signal reaching the antenna, and even if the signal receives interference, the time difference (phase difference) is kept unchanged, thereby improving the stability and accuracy of positioning; according to the scheme, high-precision and low-delay positioning is realized based on a Bluetooth AoA positioning scheme, a more accurate map for displaying an object and a person is constructed, and good user experience is provided.

Because the position state information between the first Bluetooth tag and the second Bluetooth tag can be directly calculated by using the edge calculation module 14, whether the first Bluetooth tag and the second Bluetooth tag are in a to-be-oiled state or in a waiting state or the like is still in the to-be-oiled state, decision is quickly made, and therefore non-inductive identity recognition and non-inductive oil number verification are achieved.
When the position state information between the first bluetooth tag and the second bluetooth tag is generated by the edge calculation module 14, the refueling vehicle is judged to be in a state to be refueled, the vehicle tag identity information can be directly sent to the intelligent refueling platform for verification, and the position state information and the vehicle tag identity information can also be sent to the intelligent refueling platform together for verification.
In other embodiments, when the edge calculation module 14 can generate the position state information, determine that the refueling vehicle is in the to-be-refueled state, further obtain the oil number information of the refueling vehicle from the first bluetooth tag, verify whether the oil number information is consistent with the to-be-refueled information from the to-be-refueled information corresponding to the refueling equipment (refueling gun) in the second bluetooth tag by using the edge calculation module 14, when the oil number information is consistent with the to-be-refueled information, send the refueling authorization information to the corresponding zero pipe system 15 of the refueling station, and send the refueling authorization information to the refueling terminal 16 of the refueling machine by the zero pipe system 15 of the refueling station, thereby performing; and when the verification result is inconsistent, sending the alarm information to the corresponding gas station zero pipe system 15, and sending the alarm information to the oil engine terminal 16 by the gas station zero pipe system 15 so as to stop the oil filling.
In other embodiments, the edge calculation module 14 may also directly send the fueling authorization information or the warning information to the fuel dispenser terminal 16 to perform fueling or terminate fueling.
