What is the trip code used to record the trip? What if I can't find the itinerary data?

With the escalation of epidemic prevention and control work, travel code has become an indispensable tool for everyone's daily travel. Then, what is the run-length encoding that records the itinerary? Will it not be displayed without turning on the mobile phone? Will the itinerary record after 14 be eliminated?

/kloc-will the travel code be eliminated after 0/4 days? Big data communication travel code is also one of the necessary information for people to know more about their travel situation. Generally, the previous travel records will be deleted after 14 days.

I found that on the communication itinerary card, the words city under the itinerary code turned red. In this regard, the official also made an explanation. From 0: 00 on June165438+1October 10, 2020, the travel card will be marked with the names of cities in medium and high-risk areas in red, which is only used as a travel reminder and has nothing to do with health status. Please follow the joint prevention and control mechanism of all localities for specific control policies.

What is the travel code? The big data travel card analyzes the signaling data of the mobile phone, and obtains the location of the base station where the user's mobile phone is located to accurately locate the trajectory it has traveled.

Is it true that the access big data card doesn't show where you have been? No, accessing the big data card provides location query service according to the signaling data of the user's mobile phone, which has little to do with Bluetooth location information in essence, that is, mobile phone operators can query the places they have been to where there is a signal. However, in some areas, if the cell phone signal value is weak or there is no signal, there will be deviation, and there may be places that have not been displayed. Access to the big data card is obtained through the base station where the user's mobile phone is located. The collection, transmission and processing of signaling data are highly automated, with extremely strict security and privacy protection mechanisms and high authenticity and accuracy. The driving time is usually only a few hours and will not be judged as check-in. As long as it doesn't take more than 4 hours, nothing will happen. You can rest assured that you can take the train, high-speed rail and plane.

The reason why the access big data card can't find the place it has been is 1, and the stay time is less than 4 hours. There is no record on the access big data card.

2. The shutdown signal is not good, the mobile phone has no signal, it is not the coverage area of the three major operators, and the mobile phone signaling data is wrong.

Query result rules of traffic big data travel card

The query results show the visited provinces and cities (domestic), countries and regions (international). The user's travel calculation for the first 14 days was completed in the background of the operator, and the result was delayed by one day. For example, the travel data of the first 14 days before March 4th (between February 20th and March 4th) is calculated on March 5th. In addition, because the service uses base station data, in order to ensure continuous communication and achieve no blind area coverage, the base station signals at the junction of administrative divisions may cross-cover, resulting in deviation of the results, so it can be adjusted according to other certificates.
