This technology evolved from contactless Radio Frequency Identification (RFID). In the embodiment of the application, the NB-IOT module realizes the communication of the NB wireless network and realizes the storage, the receiving and the sending of information and logic control.
In one embodiment, before the terminal device uses the road prompting method provided by the present application for the first time, the method further includes the steps of: a registration request is sent to a data center. The data center authenticates the terminal identification after receiving the registration request, and sends the terminal identification to each NB-IOT module for storage. Therefore, when the terminal corresponding to the terminal identification enters the communication range of the NB-IOT module, the NB-IOT module can communicate with the NB-IOT module and receive the communication signal sent by the NB-IOT module.
Further, in an embodiment, after the terminal device communicates with the NB-IOT module, the terminal may automatically send a road prompt request to the NB-IOT module, where the road prompt request carries a terminal identifier, and the NB-IOT module determines whether the terminal identifier can be found in the authentication prompt record, determines whether the terminal corresponding to the terminal identifier is already registered in the data center, and sends a communication signal to the terminal device if the terminal identifier can be found and determined to be authenticated. In another embodiment, before the terminal device communicates with the NB-IOT module, the terminal device further sends a road prompt request, when entering a communication range of the NB-IOT module, the NB-IOT module receives the road prompt request, and the NB-IOT module determines whether the corresponding terminal is already registered according to a terminal identifier of the road prompt request, and if so, sends a communication signal to the terminal device.

Further, in one embodiment, the NB-IOT module determines the road prompt based on the current location, which may be road related information about the surroundings from which the current location is determined. For example, if the current position is an intersection, the road prompt information may be that the current intersection on the road X changes to the left as the road X1, walks forwards as the road X2, walks rightwards as the road X3, and walks backwards as the road X4; for another example, if the current position is the end of the road X, and a left turn can enter the road Y, the road prompt information may be: turning left to enter road Y; for another example, if the current position is an intermediate link of the road Y, the road prompting information may be: the vehicle is currently positioned on a road Y and walks m meters forward to reach a branch intersection. It will be appreciated that in other embodiments, the NB-IOT module may determine the road prompt information based on the current location as well as other types of information. Further, in an embodiment, the NB-IOT module may further determine the road prompting information according to a moving direction of the terminal device, wherein the moving direction of the terminal device may be determined according to the current location received this time and the location information received several times before.

In one embodiment, the NB-IOT module and the terminal device can communicate with each other in a Bluetooth mode, an NFC mode, a GPS mode and the like; in a specific embodiment, the NB-IOT module communicates with the terminal in a near field communication manner, and the terminal device in this embodiment has a near field communication function.
In one embodiment, the terminal device needs to obtain the road prompting information of the NB-IOT module through the road prompting method after requesting registration authentication to the data center; in this embodiment, the terminal device has previously passed the registration authentication of the data center, and after the registration authentication is successful, the data center sends the terminal identifier to each NB-IOT module for storage. Further, in an embodiment, after the communication is established between the terminal device and the NB-IOT module, the NB-IOT module needs to determine whether the registration authentication has been completed according to the terminal identifier corresponding to the terminal, that is, whether the NB-IOT module stores the corresponding terminal identifier, and if so, it determines that the terminal has been registered; and may then transmit the communication signal to the terminal device.
In step S320, the current position determined by the terminal device based on the communication signal is received.
When the terminal receives the communication signals sent by the plurality of NB-IOT modules at the same time, the terminal may determine a current location of the terminal based on the plurality of communication signals and send the current location to the NB-IOT module.

In one embodiment, the prompt message returned to the terminal device is a voice prompt message, so that the terminal device can directly play the voice prompt message when receiving the voice prompt message, and convenience of blind users is improved.
In one embodiment, the NB-IOT module determines the road prompt information based on the current location, which may be road related information surrounding the current location. For example, if the current position is an intersection, the road prompt information may be that the current intersection on the road X changes to the left as the road X1, walks forwards as the road X2, walks rightwards as the road X3, and walks backwards as the road X4; for another example, the current position is the end of the road X, and a left turn may enter the road Y, and the road prompt information may be: turning left to enter road Y; for another example, if the current position is a middle link of the road Y, the road prompting information may be: the vehicle is currently positioned on a road Y and walks m meters forward to reach a branch intersection. It will be appreciated that in other embodiments, the NB-IOT module may determine the road prompt information based on the current location as well as other types of information. Further, in an embodiment, the NB-IOT module may further determine the road prompting information according to a moving direction of the terminal device, wherein the moving direction of the terminal device may be determined according to the current location received this time and the location information received several times before.

In this embodiment, each NB-IOT module may send status information to the data center at a predetermined time point; the predetermined time point may be set according to actual conditions, for example, may be set to 0 o' clock every day, or may be set to a certain time of every monday. The data center can determine whether the state of each NB-IOT module is good or not by acquiring the state information of each NB-IOT module, if the state information sent by the NB-IOT module 1 is not received at a preset time point or the received state information is abnormal, the NB-IOT module 1 is possibly abnormal, and further relevant personnel can be informed to go to the site for checking, maintaining and the like.
