The method for managing the charging pile of the electric automobile is characterized by being applied to a management system, wherein the system comprises a cloud platform and N charging management subsystems; each charging management subsystem comprises a server and a plurality of charging piles in communication connection with the server; a local area network is formed among the servers of the N charging management subsystems; the server of one charging management subsystem is a main server, and the servers of the other N-1 charging management subsystems are slave servers; n is greater than 3; the method comprises the following steps:
the method comprises the steps that a server receives vehicle entrance information, vehicle identity information, time information and charging information of a vehicle entering a parking lot; the time information comprises the time when the vehicle enters the parking place of the charging pile and the time when the vehicle leaves the parking place of the charging pile; the charging information comprises charging starting time information, charging ending time information and charging electric quantity information;
calculating parking and charging cost of the vehicle according to the received vehicle entrance information, the received vehicle identity information, the received time information and the received charging information;
the slave server shares the stored data to the master server in real time;
and triggering the main server to actively send a command of inquiring the network port state to each slave server at each interval of set time threshold, judging that the network port state of the slave server is normal when the network port information returned by the slave server is received within the set time range, and otherwise, considering that the network port state of the slave server is abnormal.
7. The electric vehicle charging pile management method according to claim 6, further comprising:
monitoring the internet access information of each slave server; and comparing the monitored network port information with pre-stored network port information, and when the network port state is abnormal, actively reporting the network port information to the main server by the slave server with the abnormal network port state.
8. The electric vehicle charging pile management method according to claim 7, further comprising:
when the state of the network port of the slave server is monitored to be abnormal, or,
when the master server does not receive the internet access information returned by the slave server within the set time range, the internet access state of internal communication of the slave server is set to be a failure state, and the internet access for external access is set to be an effective state, so that the slave server receives the access signal of the cloud platform of the internet access through the external access for management.
