when the driving times are judged to be more than the driving time threshold value and the user drives to the (i + b) th road section, the navigation equipment sends the (i + b + 1) th voice data packet to the Bluetooth voice equipment,
the method comprises the steps of collecting the time when the navigation equipment sends an i + b +1 th voice data packet as first time, collecting the time when the Bluetooth voice equipment receives the i + b +1 th voice data packet as second time, calculating a time interval value between the second time and the first time, judging that the voice data packet received by the Bluetooth voice equipment is abnormal if the time interval value is larger than or equal to a preset interval value, judging that the normal voice data packet of the Bluetooth voice equipment is abnormal if the i + b th road section to be navigated is an abnormal road section, and judging that the normal voice data packet of the Bluetooth voice equipment is normal if the time interval value is smaller than the preset interval value, wherein the i + b th road section to be navigated is a normal.
8. The big data based bluetooth navigation method according to claim 7, wherein: after the judgment of the number of times of travel being greater than the threshold number of times of travel, the method further comprises:
after the user finishes driving the route to be navigated, counting the number d of abnormal road sections in the route to be navigated, calculating the abnormal proportion d/n of the route to be navigated,
if the abnormal ratio is larger than or equal to the abnormal ratio threshold value, judging that the Bluetooth voice equipment of the user is abnormal, wherein n is the number of segments of the road section to be navigated contained in the route to be navigated, and n is a natural number;
if the abnormal proportion is smaller than the abnormal proportion threshold value, whether each section of road to be navigated in the route to be navigated is a normal road section or an abnormal road section is obtained, if a certain section of road to be navigated is an abnormal road section, whether the section of road to be navigated belongs to the problem road section database or not is judged,
if the current time point is not in the problem road section database, the time point of the road section to be navigated which is the normal road section in the history last time is collected as a first judgment time point, and if the time interval between the first judgment time point and the current time point is larger than a first judgment interval value, the road section to be navigated is stored in the problem road section database.
9. The big data based bluetooth navigation method according to claim 8, wherein: the step of obtaining whether each section of road section to be navigated in the route to be navigated is a normal road section or an abnormal road section further comprises the following steps:
if a certain section of road section to be navigated belongs to a normal road section, judging whether the section of road section to be navigated belongs to a problem road section database, if the section of road section to be navigated belongs to the problem road section database, collecting a time point of the section to be navigated which is an abnormal road section at the latest time in history as a second judgment time point, and if the time interval between the second judgment time point and the current time point is larger than a second judgment interval value, deleting the section to be navigated from the problem road section database.
10. The big data based bluetooth navigation method according to claim 8, wherein: the abnormal proportion threshold value is 1.1-1.2 times of the average value of the abnormal proportion of all the routes to be navigated when the user drives in the last month.
