Is the trip code updated in real time?

The itinerary code will not be updated in real time. The itinerary code is updated every 14 days. The user's trip calculation in the first 14 days is completed in the background of the operator. Therefore, there is a one-day delay. For example, the calculation of travel data before March 4th 14 days is calculated on March 5th. If the travel itinerary code has not been updated for more than 15 days, it is not excluded that it is a system problem. It is recommended to consult local operators.

brief introduction

Run-length coding, also known as run-length coding, run-length coding and variable-length coding, is a statistical coding. The main technology is to detect repeated bit or character sequences and replace them with their frequency of occurrence, which is more suitable for binary image coding, but not suitable for continuous tone image compression, such as photos in daily life. In order to achieve better compression effect, run-length coding is sometimes mixed with other coding methods.

After the time, the system will automatically remind the public to punch in. Currently, they need to report at least once every 14 days. The specific number of days in the later period will be adjusted according to the requirements of epidemic prevention and control, which can improve the timeliness of health codes and reflect the status quo of code holders as much as possible, which is both a reminder and a protection for everyone.

Run-length coding is very sensitive to transmission errors. If one of the symbols is wrong, it will affect the correctness of the whole coding sequence, making the run-length coding unable to recover the original data. Therefore, the methods of line synchronization and column synchronization are generally used to control the errors in a row and a column.
