The invention relates to a policeman law
enforcement terminal, a background
server side and a
data processing method. The method comprises the steps of inputting a query command or inputting law
enforcement information; sending the query command to the background
server side according to the input query command, and displaying corresponding query information fed back by the background
server side; locally storing the law
enforcement information, meanwhile sending the law enforcement information to the background
server side, stopping sending when the policeman law enforcement terminal is disconnected with the background
server side, detecting whether the connection is recovered, and if yes, sending the currently unsent law enforcement information to the background
server side. The policeman law enforcement terminal can perform data interaction with the background server side, the required information can be queried from the background server side, the input law enforcement information can be transmitted to the background server side,
breakpoint transmission is also supported, connection is automatically detected, transmission continues when the
network connection is recovered, and thus the practicability is high.
