Technical Field

Background
With the rapid development of wireless communication positioning technology, users put forward more and more positioning scenes, and realize more and more positioning requirements by means of the wireless communication positioning technology. For example, in a Positioning system based on a vehicle and a passenger, whether the passenger gets on a designated vehicle can be determined through a global Positioning system (gps), and if the Positioning position of the passenger is consistent with the Positioning position of the designated vehicle or within a set error range, the passenger can be determined to be on the vehicle or get on the vehicle; on the contrary, if the positioning position of the passenger is not consistent with the positioning position of the designated vehicle and is out of the set error range, the passenger can be determined to be absent or get off the vehicle.
However, in the GPS, the mobile terminal receives signals using GPS satellites and locates a position and a destination in real time in accordance with navigation map data. At present, the GPS still has the defects of large power consumption and high cost, and the positioning precision is not high enough particularly in a local area, so that the requirements of flexible and economic positioning scenes, particularly the positioning scenes needing high precision, cannot be well solved. For example, if the vehicle to be located is temporarily in a closed environment, which results in the blocking of the locating signal, and the personnel cannot communicate with the base station outside the vehicle, the dilemma that the personnel cannot be located occurs.
In summary, the existing wireless positioning technology needs to be improved to solve the problem that people and vehicles cannot be positioned quickly and accurately when the positioning signal is blocked or cannot communicate with an external base station due to other reasons.

Bluetooth technology is a technology that supports device short-range wireless communication, and in general, the effective communication range of a bluetooth transceiver is 10 meters. Based on the above-mentioned characteristics that the communication between the mobile communication terminal devices can be simplified by the bluetooth technology, in the invention, the bluetooth base station is installed on the traffic vehicles which can run, such as vehicles like automobiles, trains, subways, etc., or traffic vehicles in special working environments like other engineering, transportation, etc. When the vehicle runs to the position where the fixed base station signal cannot be received or the receiving quality of the fixed base station signal is poor, the vehicle is provided with the Bluetooth base station, the Bluetooth base station still can transmit the signal, and accordingly, passengers or drivers on the vehicle can smoothly position the vehicle by receiving the signal transmitted by the Bluetooth base station.
The passenger or the driver carries the Bluetooth terminal with the user, and the Bluetooth terminal can adopt a mobile terminal with a Bluetooth function, wherein the mobile terminal comprises but is not limited to a tablet computer, a mobile phone, a PDA, a notebook computer, an intelligent watch or other wearable equipment and the like. In various embodiments of the present invention described below, each bluetooth terminal has a separate identification card for uniquely identifying the identity information of the bluetooth terminal to distinguish it from other bluetooth terminals.
After the Bluetooth function of the Bluetooth terminal is started, once the distance between a passenger or a driver carrying the Bluetooth terminal and a vehicle provided with the Bluetooth base station is within an effective communication distance range, the Bluetooth terminal and the Bluetooth base station can be successfully connected in a pairing mode, and at the moment, a remote controller (such as an upper computer) can record the connection success. Each increment of the record of successful connection indicates a higher probability of a passenger or driver being located on the vehicle. Therefore, a threshold value of the connection success frequency can be preset according to the running environment of the vehicle or objective conditions such as the performance version number of the Bluetooth base station and the Bluetooth terminal or the requirement of central control, when the connection success frequency sent by the identification card signal received by the remote controller of the Bluetooth terminal is greater than or equal to the threshold value, the passenger or the driver can be judged to be on the vehicle, otherwise, if the connection success frequency is less than the threshold value, the passenger or the driver is judged not to be on the vehicle. The higher the required judgment accuracy, the higher the threshold value can be set.
Example one
Reference is next made to fig. 1. As shown in FIG. 1, one embodiment of the present invention provides a method of determining a person's positional relationship with a vehicle.
Step S101 is a mapping step, in which the bluetooth base station maps information of the first indication area and the second indication area corresponding to the bluetooth base station number from the remote controller.
Each Bluetooth base station has a unique identity number, and for the unique identity number, a corresponding indication area is arranged on a storage area of the remote controller, and the information of the indication area is mapped to the Bluetooth base station. Further, the indication area is divided into two sub-areas, namely a first indication area and a second indication area. The first indication area is used for recording and indicating the times of successful connection between the Bluetooth terminal and the Bluetooth base station, and the second indication area is used for recording and indicating the times of unsuccessful connection between the Bluetooth terminal and the Bluetooth base station. The initial values of the first indication area and the second indication area are both set to 0.
Step S102 is a reception step of receiving a person signal every time T1.
In step S102, the Bluetooth base station is configured to receive a person signal every fixed time T1, for example, every 18-22 ms. Preferably, the interval time T1 is 20 ms. In the embodiment of the invention, the personnel signal is a carried identification card signal of the Bluetooth terminal.
Step S103 is a calculation step of incrementing the value V1 of the first indication area and resetting the value V2 of the second indication area if the bluetooth base station receives the person signal, and incrementing the value V2 of the second indication area and resetting the value V1 of the first indication area if the bluetooth base station does not receive the person signal.
Specifically, if the bluetooth base station receives a bluetooth terminal identification card signal carried by a person, the value V1 of the bluetooth terminal identification card is correspondingly increased by 1 in a first indication area corresponding to the identity number of the bluetooth base station, if the bluetooth base station continuously receives the bluetooth terminal identification card signal, the value V1 of the bluetooth terminal identification card in the first indication area is continuously increased by 1, and the value V2 of the second indication area is reset while the value V1 of the first indication area is increased by 1 each time.
Similarly, in step S103, if the bluetooth base station fails to successfully receive the id card signal of the bluetooth terminal, the value V2 of the bluetooth terminal id card is increased by 1 correspondingly in the second indication area corresponding to the identity number of the bluetooth base station, if the bluetooth base station fails to continuously receive the bluetooth terminal id card signal, the value V2 of the bluetooth terminal id card in the second indication area is continuously increased, and the value V1 of the first indication area is reset while the value V2 of the second indication area is increased each time.
Step S104 is a comparison step, and compares the value V1 of the first indication region and the value V2 of the second indication region with the preset threshold TH, respectively, according to the calculation result of step S103.
Specifically, in step S104, the value of the first indication region and the value of the second indication region acquired in step S103 are respectively compared with a preset threshold TH. The specific comparison method comprises the following steps: and comparing the value V1 of the first indication area and the value V2 of the second indication area with a preset threshold TH respectively every time the Bluetooth base station receives the signal of the Bluetooth terminal identification card. The value V1 of the first indication area is compared with the preset threshold TH to determine whether the number of times of the bluetooth base station successfully receiving the bluetooth terminal identification card signal satisfies the preset condition, and the value V2 of the second indication area is compared with the preset threshold TH to determine whether the number of times of the bluetooth base station successfully receiving the bluetooth terminal identification card signal satisfies the preset condition. As described above, the preset threshold may be preset according to the environment in which the vehicle travels, objective conditions such as the performance version number of the bluetooth base station and the bluetooth terminal, or the degree of demand for central control. The higher the required judgment accuracy, the higher the threshold value can be set. The preset threshold of the first indication area and the preset threshold of the second indication area may be the same or different, and in this embodiment, the preset threshold is preferably set to 5 to 8 times, and may be set to 10 if higher determination accuracy is required.
Step S105 is a determination step for determining the positional relationship between the person and the vehicle based on the comparison result of step S104. In step S105, it is determined whether the person is located on the vehicle according to the comparison result of step S104, that is, the magnitude relation of the value V1 of the first indication area to the preset threshold TH, and the magnitude relation of the value V2 of the second indication area to the preset threshold TH.
Example two
Reference is next made to fig. 2. Another embodiment of the present invention, as shown in fig. 2, provides a method of determining a person's positional relationship with a vehicle.
Step S201 is a mapping step, in which the bluetooth base station maps information of the first indication area and the second indication area corresponding to the bluetooth base station number from the remote controller.
Each bluetooth base station has a unique identity number, and for the unique identity number, a corresponding indication area is set on the storage area of the remote controller, that is, the indication area corresponding to the number is mapped with the bluetooth base stations corresponding to the number one by one. Further, the indication area is divided into two sub-areas, namely a first indication area and a second indication area. The first indication area is used for recording and indicating the times of successful connection between the Bluetooth terminal and the Bluetooth base station, and the second indication area is used for recording and indicating the times of unsuccessful connection between the Bluetooth terminal and the Bluetooth base station. The initial values of the first indication area and the second indication area are both set to 0.
Step S202 is a receiving step, and receives the person signal once at interval T1. In step S202, the Bluetooth base station is configured to receive a person signal every fixed time T1, for example, every 18-22 ms. Preferably, the interval time T1 is 20 ms. In the embodiment of the invention, the personnel signal is a carried identification card signal of the Bluetooth terminal.
Step S203 is a calculation step of incrementing the value V1 of the first indication area and resetting the value V2 of the second indication area if the bluetooth base station receives the person signal, and incrementing the value V2 of the second indication area and resetting the value V1 of the first indication area if the bluetooth base station does not receive the person signal.
Specifically, if the bluetooth base station receives a bluetooth terminal identification card signal carried by a person, the value V1 of the bluetooth terminal identification card is correspondingly increased by 1 in a first indication area corresponding to the identity number of the bluetooth base station, if the bluetooth base station continuously receives the bluetooth terminal identification card signal, the value V1 of the bluetooth terminal identification card in the first indication area is continuously increased by 1, and the value V2 of the second indication area is reset while the value V1 of the first indication area is increased by 1 each time.
Similarly, in step S203, if the bluetooth base station fails to successfully receive the id card signal of the bluetooth terminal, the value V2 of the bluetooth terminal id card is increased by 1 correspondingly in the second indication area corresponding to the identity number of the bluetooth base station, if the bluetooth base station fails to continuously receive the bluetooth terminal id card signal, the value V2 of the bluetooth terminal id card in the second indication area is continuously increased, and the value V1 of the first indication area is reset while the value V2 of the second indication area is increased each time.
Step S204 is a comparison step, comparing the value V1 of the first indication region and the value V2 of the second indication region with the preset threshold TH, respectively, according to the calculation result of step S103.
Specifically, in step S204, the value V1 of the first indication region and the value V2 of the second indication region acquired in step S203 are respectively compared with a preset threshold TH. The specific comparison method comprises the following steps: and comparing the value V1 of the first indication area and the value V2 of the second indication area with a preset threshold TH respectively every time the Bluetooth base station receives the signal of the Bluetooth terminal identification card. The value V1 of the first indication area is compared with the preset threshold TH to determine whether the number of times of the bluetooth base station successfully receiving the bluetooth terminal identification card signal satisfies the preset condition, and the value V2 of the second indication area is compared with the preset threshold TH to determine whether the number of times of the bluetooth base station successfully receiving the bluetooth terminal identification card signal satisfies the preset condition. As described above, the preset threshold may be preset according to the environment in which the vehicle travels, objective conditions such as the performance version number of the bluetooth base station and the bluetooth terminal, or the degree of demand for central control. The higher the required judgment accuracy, the higher the threshold value can be set. The preset threshold of the first indication area and the preset threshold of the second indication area may be the same or different, and in this embodiment, the preset threshold is preferably set to 5 to 8 times, and may be set to 10 if higher determination accuracy is required.
Step S205 is a determination step of determining the positional relationship between the person and the vehicle based on the comparison result of step S204.
Further, step S205 includes a position relationship determination step S206, which determines the position relationship between the person and the vehicle according to the current comparison result.
Specifically, if the value V1 of the first indication area is greater than or equal to the preset threshold TH, it indicates that the bluetooth base station successfully receives the bluetooth terminal identification card signal for multiple consecutive times, and therefore, it can be determined that the person carrying the bluetooth terminal is located on the vehicle on which the bluetooth base station is installed; similarly, if the value V2 of the second indication area is greater than or equal to the preset threshold TH, it indicates that the bluetooth base station fails to receive the bluetooth terminal identification card signal for multiple times, and therefore, it can be determined that the person carrying the bluetooth terminal is not located on the vehicle on which the bluetooth base station is installed.
And step S205 also comprises a state change judging step S207, which is used for determining the state change of the positions of the personnel and the vehicle according to the current position relation judgment result and the previous position relation judgment result.
Specifically, if the current position relationship judgment result is that the person is on the vehicle and the previous position relationship judgment result is that the person is not on the vehicle, judging that the state change of the person is changed from getting-off to getting-on; and if the current position relation judgment result indicates that the personnel is not on the vehicle and the previous position relation judgment result indicates that the personnel is on the vehicle, judging that the state change of the personnel is changed from getting on the vehicle to getting off the vehicle.

And further divides the indication area into two sub-areas, i.e., a first indication area and a second indication area. The first indication area is used for recording and indicating the times of successful connection between the Bluetooth terminal and the Bluetooth base station, and can also be called as a boarding area; the second indication area is used for recording and indicating the number of times of connection failure between the bluetooth terminal and the bluetooth base station, and can also be called as a get-off area.

After the bluetooth function of the bluetooth terminal 402 is turned on, once the distance between the person carrying the bluetooth terminal 402 and the vehicle equipped with the bluetooth base station 401 is within the effective bluetooth communication distance range, the person and the vehicle can be successfully paired and connected.
The Bluetooth base station 401 is configured to receive the identification card signal of the Bluetooth terminal 402 once every fixed time T1, for example, every 18 to 22 ms. Preferably, the interval time T1 is 20 ms.
If the bluetooth base station 401 receives an identification card signal of the bluetooth terminal 402 carried by a person, in a first indication area of the remote controller 403 corresponding to the identity number of the bluetooth base station, the value V1 of the identification card of the bluetooth terminal 402 is increased by 1, and the value V2 of a second indication area is reset.
