All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
According to an embodiment of the present invention, there is provided a positioning method for a terminal, as shown in fig. 1, the method includes steps S101 to S103 as follows:
step S101, positioning information is received, wherein the positioning information refers to positioning information of a terminal.
In particular, when the positioning terminal enters indoors or outdoors, the positioning terminal can receive the positioning signal sent by the positioning node arranged indoors or outdoors. For example, when a positioning terminal enters the room, a signal of a bluetooth beacon arranged in advance may be received, at this time, indoor positioning may be started, positioning information representing the position of the terminal is received, and the received positioning information is transmitted to a server through a gateway or a base station for subsequent calculation and processing.
Step S102, judging whether the positioning information meets a preset positioning switching condition.
During the concrete implementation, when the positioning terminal leaves above-mentioned indoor space, the signal intensity that the terminal can't receive bluetooth beacon or received bluetooth beacon is relatively weak, if still adopt the mode of indoor location this moment can't realize the accurate location to the terminal. In another situation, since the bluetooth signal can be transmitted several tens of meters away, there is a possibility that the positioning terminal can still receive the signal of the bluetooth beacon even though the positioning terminal is located outdoors, and it is mistaken that the positioning terminal is still located indoors, which causes a large positioning error. In addition, the bluetooth signal is easily blocked by buildings and the like, so that the transmission distance of the bluetooth signal is greatly reduced, and therefore, the situation that the positioning terminal still stays indoors but thinks that the positioning terminal has arrived outdoors because the positioning terminal cannot receive the signal of the bluetooth beacon due to the fact that the signal of the bluetooth beacon is not fully covered can occur, and therefore, the positioning mode is switched from indoor positioning to outdoor positioning by mistake.
In order to solve the problem that the original positioning method can not realize accurate positioning any more when the positioning terminal moves from indoor to outdoor or from outdoor to indoor, the method for switching the indoor and outdoor positioning modes is provided, and whether the existing positioning mode really needs to be switched or not is firstly judged before the positioning mode is switched, so that wrong positioning switching is avoided.
And step S103, determining whether to switch the positioning mode according to the judgment result, wherein the switching of the positioning mode refers to switching from indoor positioning to outdoor positioning or switching from outdoor positioning to indoor positioning.
In specific implementation, whether the positioning mode is switched from indoor positioning to outdoor positioning or from outdoor positioning to indoor positioning or not is determined according to the judgment result of the terminal.
Preferably, determining whether to switch the positioning mode according to the determination result includes steps S1031 to S1032:
and step S1031, if the judgment result is that the positioning information meets the preset positioning switching condition, switching the positioning mode.
In specific implementation, when the positioning information of the terminal meets a preset positioning switching condition, switching the positioning mode, wherein the specific switching mode is switching from indoor positioning to outdoor positioning or switching from outdoor positioning to indoor positioning. For example, when the positioning information sent by the bluetooth beacon received by the terminal meets the preset positioning switching condition, which indicates that the positioning terminal has moved outdoors, the indoor bluetooth positioning is switched to the outdoor satellite positioning or GPS positioning.
Step S1032, if the determination result is that the positioning information does not satisfy the preset positioning switching condition, the positioning mode is not switched.
In specific implementation, when the positioning information of the terminal does not meet the preset positioning switching condition, the switching of the positioning mode is not performed, and the original positioning mode is still maintained. For example, when the positioning information sent by the bluetooth beacon received by the terminal does not meet the preset positioning switching condition, it indicates that the positioning terminal is still indoors, and the bluetooth positioning mode is still adopted.
Preferably, the positioning information includes bluetooth positioning information or satellite positioning information, the indoor positioning includes bluetooth positioning, the outdoor positioning includes satellite positioning, as shown in fig. 2, determining whether to switch the positioning mode according to the determination result further includes steps S201 to S203 as follows:

During specific implementation, the indoor positioning mode in the application can include bluetooth positioning, WIFI positioning or UWB (ultra wide band) positioning and other modes, the outdoor positioning can include satellite positioning or GPS positioning mode, and specific positioning mode selection can be configured according to actual needs, and is not specifically limited herein. When the positioning terminal is positioned indoors in a bluetooth positioning mode, the signal intensity of the received bluetooth signal needs to be monitored in real time, that is, the signal intensity changes to be used as a prerequisite for judging whether the terminal moves from indoors to outdoors. As a preferred implementation manner of the embodiment of the present application, a first preset signal strength threshold value, such as a bluetooth positioning signal strength threshold value, is preset, and when the signal strength of a bluetooth signal received by a positioning terminal is lower than the threshold value, it indicates that the positioning terminal may have moved outdoors or may still be indoors but the transmission of the bluetooth signal is interfered, and the like.
Step S202, determining whether the satellite positioning information is received within a first preset time period.
In specific implementation, in order to save energy consumption of the positioning terminal, a certain time period can be preset to determine the time length for starting satellite positioning, and the time length can be flexibly set according to actual needs. For example, when the signal strength of the bluetooth signal received by the positioning terminal is lower than a threshold, which indicates that the terminal may have moved outdoors or may still be indoors but the transmission of the bluetooth signal is interfered, at this time, whether the terminal has moved outdoors is determined by starting an outdoor positioning manner, such as satellite positioning, within a preset time period, to assist in determining whether the terminal has moved outdoors, and whether the positioning terminal can receive a satellite positioning signal with sufficient strength within the preset time period, preferably, whether the signal strength of the satellite positioning signal received by the positioning terminal within the preset time period reaches a certain preset threshold.
Step S203, if the satellite positioning information is received within the first preset time period, switching the positioning mode from the bluetooth positioning to the satellite positioning.
In specific implementation, if the positioning terminal receives the satellite positioning signal within the preset time period and the signal strength of the satellite positioning signal also reaches a certain threshold, which indicates that the positioning terminal has moved from indoor to outdoor, the bluetooth positioning is turned off at this time, and the automatic switching of the positioning mode from indoor positioning to outdoor positioning is completed.
Preferably, after determining whether the satellite positioning information is received within the first preset time period, the method further includes the following step S204:
step S204, if the satellite positioning information is not received in the first preset time period, the satellite positioning is closed.
In specific implementation, if the positioning terminal does not receive the satellite positioning signal or the received satellite positioning signal strength is lower than the preset signal strength threshold value in the preset time period, it is indicated that the positioning terminal still stays indoors, and at this time, the satellite positioning is turned off.
Preferably, as shown in fig. 3, determining whether to switch the positioning mode according to the determination result further includes the following steps S301 to S303:
step S301, if the signal strength of the satellite positioning information is lower than a second preset signal strength threshold value, starting the Bluetooth positioning.
In specific implementation, when outdoor positioning is performed on the positioning terminal through satellite positioning or GPS positioning, the signal strength of the received satellite signal needs to be monitored in real time, that is, the signal strength changes are used as a prerequisite for determining whether the terminal moves from outdoor to indoor. As a preferred implementation manner of the embodiment of the present application, a second preset signal strength threshold value, such as a satellite positioning signal strength threshold value, is preset, and when the signal strength of a satellite positioning signal received by a positioning terminal is lower than the threshold value, it indicates that the positioning terminal may have moved indoors or may still be outdoors but the transmission of the satellite signal is interfered, and the like.
Step S302, determining whether the bluetooth positioning information is received within a second preset time period.
During specific implementation, in order to save energy consumption of the positioning terminal, a certain time period can be preset to determine the time length for starting the bluetooth positioning, and the time length can be flexibly set according to actual needs. For example, when the signal strength of the satellite positioning signal received by the positioning terminal is lower than a threshold, which indicates that the terminal may have moved indoors or may still be outdoors but the transmission of the satellite positioning signal is interfered, at this time, whether the terminal has moved indoors is determined by starting an indoor positioning manner, such as bluetooth positioning, within a preset time period, to assist in determining whether the terminal has moved indoors, and whether the positioning terminal can receive a bluetooth positioning signal with sufficient strength within the preset time period, preferably, whether the signal strength of the bluetooth positioning signal received by the positioning terminal within the preset time period reaches a certain preset threshold.
Step S303, if the bluetooth positioning information is received within the second preset time period, switching the positioning mode from the satellite positioning to the bluetooth positioning.
In specific implementation, if the positioning terminal receives the bluetooth positioning signal within the preset time period and the signal strength of the bluetooth positioning signal also reaches a certain threshold, which indicates that the positioning terminal has moved from outdoor to indoor, the satellite positioning is turned off at this time, and the automatic switching of the positioning mode from outdoor positioning to indoor positioning is completed.
