if the quantity of the newly added vehicle information is not greater than a preset threshold value, the upper computer is used for transmitting the newly added vehicle information as a control instruction;
the upper computer distributes data transmission channels corresponding to the information to be processed for the information to be processed of each category;
the upper computer acquires the priority corresponding to each category of information to be processed;
the upper computer transmits the information to be processed to a ticket box controller through a data transmission channel corresponding to the information to be processed according to the priority sequence;
the card reader reads the identity information of the card;
the ticket box controller receives the identity information read by the card reader;
the ticket box controller judges whether the identity information is legal or not according to local identity information prestored in a local database;
and under the condition that the identity information is legal, the ticket box controller generates a third release instruction and controls the node to be opened according to the third release instruction.
6. The method of claim 5, wherein the upper computer transmits the information to be processed to the ticket box controller through a data transmission channel corresponding to the information to be processed in order of priority, and the method comprises the following steps:
the upper computer receives the receiving completion reminding information from the ticket box controller after finishing issuing the information to be processed with the same priority;
