The signal receiver 111 may also be a signal receiver on a user's personal device, such as a mobile phone.

Referring to fig. 2, fig. 2 shows a schematic flowchart of a method for determining a parking area provided by the present application.

As shown in fig. 2, the method may include the steps of:

step 201, acquiring a wireless signal transmitted by a signal transmitter built in a positioning device.

Including but not limited to bluetooth wireless signals and near field communication wireless signals. This embodiment takes bluetooth wireless signals as an example to explain the present solution.

The present embodiment employs the bluetooth technology to detect whether the vehicle reaches the parking area. The Bluetooth technology can realize short-distance data exchange among the fixed equipment, the mobile equipment and the building personal area network, and the Bluetooth technology supports point-to-point and point-to-multipoint communication, so that a single positioning device can position a plurality of vehicles. And the short distance of bluetooth transmits the higher accuracy that the vehicle location brought (because bluetooth is the communication technology in a short distance range, only when the vehicle gets into the broadcast range of bluetooth signal, just can receive the bluetooth signal, in case surpass the broadcast range of bluetooth signal, then can't receive the bluetooth signal, through above-mentioned mode, can avoid appearing the emergence of the condition such as location drift).

The embodiment continuously sends the wireless signals to the surroundings through the signal transmitter in the positioning device, and the processor acquires the wireless signals through the Bluetooth receiving device.

Step 202, acquiring a unique identification code of the positioning device in the wireless signal.

In practical application scenarios, due to the large number of applications of bluetooth technology, a parking area may be filled with a plurality of bluetooth signals (bluetooth signals sent by other devices with bluetooth functions, such as a positioning device sharing a vehicle or a mobile phone bluetooth), which may easily cause a vehicle to be mis-positioned, for example: because the vehicle cannot distinguish the target positioning device from the non-target positioning device, when the vehicle receives a wireless signal of the non-target positioning device, the processor still judges that the vehicle enters the parking area (a certain distance exists between the target positioning device and the non-target positioning device), and error positioning is caused.

Therefore, in the embodiment of the application, the unique identification codes corresponding to the plurality of positioning devices are set so as to be used for distinguishing the positioning devices or the mobile phone Bluetooth of other shared vehicles. And when the wireless signal is acquired, acquiring the unique identification code of the positioning device in the wireless signal.

And step 203, if the unique identification code is a pre-stored identification code, determining whether the vehicle is in a parking area according to the power of the wireless signal.

Comparing the unique identification code with the pre-stored identification code.

As an embodiment of the present application, when the pre-stored identification code is an identification code in a memory, the unique identification code is directly compared with the pre-stored identification code in the memory.

As another embodiment of the application, when the pre-stored identification code is an identification code in a database, the unique identification code is sent to a background, the background acquires the identification code in the database, and compares the unique identification code with the pre-stored identification code to obtain a comparison result. The background sends the comparison result to the vehicle.

And determining whether the unique identification code is a pre-stored identification code or not by the above mode, if so, acquiring the power of the wireless signal, and determining whether the vehicle is in a parking area or not according to the power of the wireless signal.

Due to the nature of signal propagation, the power of a wireless signal tends to fade as the propagation distance of the wireless signal increases. Therefore, in the embodiment, whether the vehicle is in the parking area can be determined by the power of the wireless signal.

As an embodiment of the present application, it may also be determined whether the vehicle is in the parking area according to other characteristics or parameters of the wireless signal, including but not limited to the intensity and frequency of the signal, the wavelength, and the like.

And if the unique identification code is not a pre-stored identification code, continuously receiving other wireless signals.

Step 1032, if the power is smaller than the preset power, determining that the vehicle is not in the parking area.

When the power of the wireless signal is smaller than the preset power, the distance between the vehicle and the positioning device is larger, and the fact that the vehicle does not enter a parking area can be judged.

Specifically, if the power is greater than or equal to the preset power, determining that the vehicle is in a parking area includes: and if the power is greater than or equal to the preset power and the duration exceeds the preset duration, determining that the vehicle is in the parking area.

In an actual application scenario, since the vehicle is moving continuously, the vehicle may move out of the parking area after reaching the parking area at a certain moment, which causes the vehicle to be positioned incorrectly. In order to prevent the above situation, in this embodiment, when the power is greater than or equal to the preset power, it is determined whether the duration of the power being greater than or equal to the preset power exceeds the preset duration. And when the power is greater than or equal to the preset power and the duration exceeds the preset duration, determining that the vehicle is in a parking area. And when the power is greater than or equal to the preset power and the duration does not exceed the preset duration, determining that the vehicle is not in the parking area.

Specifically, when the wireless signals are multiple, if the unique identification code is a pre-stored identification code, determining whether the vehicle is in a parking area according to the power of the wireless signals, including: and if any one of the unique identification codes corresponding to the plurality of wireless signals is the pre-stored identification code, determining whether the vehicle is in a parking area according to the power of the wireless signals.

case one, a plurality of wireless signals are all signals sent by the target positioning device.

In case two, the plurality of wireless signals are all signals emitted by non-target positioning devices.

And if the unique identification codes corresponding to the plurality of wireless signals are not the pre-stored identification codes (namely, the condition II), determining that the vehicle is not in the parking area.

Specifically, the determining whether the vehicle is in a parking area according to the power of the wireless signal includes: and if the power of any one wireless signal in the plurality of wireless signals is greater than the preset power, determining that the vehicle is in the parking area.

When the power of any one wireless signal is larger than the preset power, the distance between the vehicle and the positioning device corresponding to the wireless signal with the power larger than the preset power is smaller, and the vehicle can be judged to enter the parking area.

In the embodiment, the wireless signals transmitted by the signal transmitter built in the positioning device are acquired; acquiring a unique identification code of the positioning device in the wireless signal; and if the unique identification code is a pre-stored identification code, determining whether the vehicle is in a parking area according to the power of the wireless signal.
