S38：Control unit takes the mean value of the two of gap minimum in L1, L2 and L3 as final location information.
S39：Whether control unit judges to position number more than m times, if being more than, S310 is entered step, otherwise, into step
Rapid S311, wherein the acquiescence value of m is 3, can be adjusted according to actual conditions.
S310：Control unit takes L1 as final location information.
S311：It positions number and increases 1, reposition, be transferred to step S31.
Likewise, when control unit 15 judges that current positioning signal is GPS and WIFI available, by GPS+WIFI into
The flow of row integrated positioning is similar with the process step of GPS+NB-IoT shown in Figure 14.
Figure 15 is the flow diagram 4 of localization method in specific embodiment provided by the invention, locating module high-precision mould
Under formula, when gps signal is not available, it is combined positioning using NB-IoT+WIFI, as shown in figure 15.Specifically, locating module
High precision mode NB-IoT+WIFI integrated positioning flows include following flow：
S41：Control unit judges whether NB-IoT, WIFI signal intensity meet location condition, when NB-IoT, WIFI signal
When intensity is satisfied by location condition, then NB-IoT and WIFI positioning methods is selected to carry out comprehensive positioning.
S42：Control unit starts NB-IoT positioning units and is positioned, and NB-IoT positioning units are by obtaining current environment
The signal strength of lower NB-IoT communication base stations, and from operator's base station position information of background server acquisition, positioned
Obtain location information L2 (longitude and latitude).
S43：Control unit starts WIFI positioning units and is positioned, and obtains location information L3 (longitude and latitude).
S44：Control unit calculate L2 and L3 air line distance, if the two distance difference be less than n (parameter value, it is adjustable, such as
200 meters), then S45 is entered step, S46 is otherwise entered step.Judge to position whether number is more than m times again.
S45：Control unit takes the mean value of L2 and L3 as final location information (longitude and latitude).
S46：Control unit judges that whether position number is less than more than m times, if so, carrying out step S47, otherwise enters step
S48。
S47：Control unit then takes m location information (L21~L2mAnd L31~Lm) mean value as final location information
L (longitude and latitude).
S48：It positions number and increases 1, reposition, be transferred to step S41.
