[0033] In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

[0034] Embodiment 1

[0035] FIG. 1 is a flowchart of an implementation of an Internet of Things parking guidance method according to an embodiment of the present invention. The method is applied to an Internet of Things parking guidance device, including but not limited to a server, a mobile terminal, as shown in FIG. The IoT parking guidance method may include the following steps:

[0036] S101, configuring a random backoff of the wireless network;

[0037] S102: Receive a first chirp signal broadcasted by the Internet of Things navigator device in the random backoff, receive a second chirp signal broadcast by the first positioning device, and a third chirp broadcast by the second positioning device. signal;

[0038] receiving, in the random backoff, a first chirp signal broadcasted by the Internet of Things navigator device, receiving a second chirp signal broadcast by the first positioning device, and a third chirp signal broadcast by the second positioning device, Receiving a second chirp signal broadcast by the first positioning device and a third chirp signal broadcast by the second positioning device.

[0039] The chirp signal generation module in the Internet of Things navigator can be configured to transmit chirp signals in a particular frequency mode, such as high frequency noise, low frequency noise.

[0040] an Internet of Things navigator configured to broadcast a first chirp signal;

[0041] a first positioning device configured to broadcast a second chirp signal, the second chirp signal indicating reception of the first chirp signal and a message regarding when the first chirp signal is received a piece of information; and

[0042] a second positioning device configured to broadcast a third chirp signal, the third chirp signal indicating reception of the first chirp signal and the second chirp signal and information about where to receive The first inter-signal signal and the second inter-turn information of the second chirp signal.

Wherein the first mobile computing device is configured to use the first inter-turn information and the second inter-turn signal The location of the second mobile computing device is determined.

[0044] S103. Generate vehicle positioning coordinates of the Internet of Things navigator according to the first chirp signal and the second chirp signal and the third chirp signal.

[0045] wherein the second chirp signal and the third chirp signal are sent by the positioning device, and the distance between the Internet of Things navigator device and the positioning device may be based on the chirp signal broadcast and the chirp signal receiving time determine.

[0046] Using the 啁啾 communication to create a parking guide, the encoding application in the Internet of Things Navigator device can calculate the distance from the positioning device. The encoding application generates an approximate orientation for another user by text indicating the direction and distance. The encoding application can insert an arrow into the video file played on the IoT navigator device to indicate the direction that the IoT navigator device should go to the free parking space.

[0047] The two positioning devices can propagate the chirp signals to each other to calculate the distance between them. The positioning device and the IoT navigator device can also listen to and distinguish between these two signals, which enables the precise location of the IoT Navigator device to be calculated. Direction information can be transmitted to the IoT navigator device.

[0048] The chirp signal generating module of the two positioning devices may be configured to transmit the chirp signal in a specific frequency mode, such as high frequency noise, low frequency noise.

[0049] The chirp signal may be transmitted by the positioning device and received by another positioning device located nearby. The inter-turn interval between the transmission of the chirp signal and the reception of the chirp signal can be used to estimate how far the two IoT parking guidance devices are from each other.

[0050] In this example, the first positioning device can transmit its own chirp signal and can receive the chirp signal transmitted by the positioning device. The difference between the high frequency signal and the low frequency signal can be used to determine the distance from the first (or transmitting) positioning device and the second (or receiving) positioning device.

[0051] By the same token, in this example, the first positioning device can transmit its own chirp signal and can receive the chirp signal transmitted by the Internet of Things navigator device. The difference between the high frequency signal and the low frequency signal can be used to determine the distance from the IoT navigator device to the first positioning device.

[0052] By the same token, in this example, the second positioning device can transmit its own chirp signal and can receive the chirp signal transmitted by the Internet of Things navigator device. The difference between the high frequency signal and the low frequency signal can be used to determine the distance from the IoT navigator device to the second positioning device.

[0053] The positioning algorithm used includes at least one of a Time Difference of Arrival (TOA) algorithm and a Time Difference of Arrival (TDOA) algorithm. [0054] TDOA positioning is a method of positioning using inter-turns. The distance of the signal source can be determined by measuring the signal arriving at the station's turn. The position of the signal can be determined by using the distance from the signal source to the IoT navigator device, the first positioning device, and the second positioning device (centered at the monitoring station and the radius is rounded). However, it is generally more difficult to measure in the absolute time. By comparing the signal to the inter-turn difference between the IoT navigator device, the first positioning device, and the second positioning device, the IOT parking guidance device can be focused, and the distance difference is the long axis. The hyperbola, the intersection of the hyperbola is the position of the signal.

[0056] using a series of low frequency and high frequency broadcast chirp signal modes;

[0062] The remaining free parking spaces are obtained in the following manner, as detailed below:

[0063] The first way:

[0064] After the initialization, a parking space number is assigned to each parking space in the parking lot, and a correspondence relationship between the parking space number, the parking space, and the parking space geographic coordinates is established. When the parking space is occupied, modify the parking space to the occupied parking space.

[0065] The occupied parking space is removed from all parking spaces, and the remaining parking spaces are the remaining free parking spaces.

[0068] The occupied parking spaces are removed from all parking spaces, and the remaining parking spaces are the remaining free parking spaces.

[0069] wherein, whether the parking state of the parking space changes is detected by detecting a change in the magnetic field at the parking space or detecting a change in light at the parking space.

[0070] It should be noted that the model parameters include shape parameters and model numbers.

[0074] The navigation line and the navigation arrow are transmitted to the in-vehicle IoT parking guidance device of the vehicle, and the vehicle is guided to enter a free parking space corresponding to the shape parameter of the vehicle.
