Detailed Description
The present invention will be further described with reference to the following examples and drawings, but the present invention is not limited thereto.
Example 1: the hot standby method of the intelligent parking integrated machine comprises a host machine and a standby machine, wherein the host machine and the standby machine are connected through a TCP/IP network, the host machine and the standby machine share a database, the front end of the database is connected with a Web visual interface, and the rear end of the database is connected with a java background; parameters of configuration files in the database are modified through java background operation to serve as constants and variables required by the host and the standby machine, the database is closed and started through matching with the bat script according to a fixed sequence, and dual-machine hot standby of the host and the standby machine is achieved. Specifically, parameters of configuration files in a database, server-id (server numbers are changed into nonrepeating values), replay-align-table (a synchronization table needing service addition and being ignored), bind-address (a database ip address is added), slave-skip-errors (a parameter that the main database and the standby database cannot stop due to abnormal shutdown of the configuration server is all) are modified, the configuration of the main database is modified, the data of the main database is remotely backed up, the remote data is restored to the standby database, the main database is restarted, the synchronization node of the main database is obtained through an SQL statement, the synchronization node of the main database is set to the standby database through an SQL statement, and the standby database is restarted to realize the hot standby of the main computer and the standby computer. The host and the slave are connected through a TCP/IP network, the host is in a working state under normal conditions, the slave is in a monitoring state, once the slave finds that the host is abnormal, the slave can replace the host within a short time, and the function of the host is completely realized.
Further, the host and the standby machine independently process respective entrance and exit and parking payment related logic for simultaneous use by the client, and the logic that the ActiveMQ receives the message to modify the database is suspended if the host and the standby machine are detected as the host of the standby database by analyzing the configuration file.
When the host fails under abnormal conditions, the standby computer automatically takes effect and automatically switches ip to set the host as the host, so that seamless use of clients is provided. Specifically, after the standby machine does not respond to the host machine through heartbeat detection (namely a heartbeat mechanism, the heartbeat mechanism is a mechanism for regularly sending a self-defined structure body (heartbeat packet) to enable the opposite side to know that the standby machine is still alive so as to ensure the connection validity), the local IP is modified into the original IP of the host machine in the database, the configuration file in the database is automatically modified through a java background, the configuration is enabled to take effect through a bat script, and then the IP configuration data of the host machine and the standby machine in the database are updated so that the parking logic can be normally used.
And further, after the host and the standby machine are switched, if the abnormal host is recovered to be normal, the current host and the abnormal host obtain a working host through negotiation, the configuration file in the database is automatically modified through the java background, the configuration is enabled to take effect through the bat script, and then the IP configuration data of the host and the standby machine in the database are updated to enable the parking logic to be normally available.
Example 2: on the basis of the embodiment 1, as shown in fig. 1, the host and the standby machine are connected through a switch, and the switch is in wired connection with the database; the host and the standby machine are respectively provided with a 5G module, and the 5G module is wirelessly connected with the database; the host and the standby machine are respectively provided with a parking charging system, a visual intercom system and a monitoring system; the monitoring system is connected with a video gateway through a switch, and the video gateway is connected with a database;
when the wired network is normal, the parking lot video data shot by the host monitoring system is transmitted to the database from the switch and the video gateway in a wired mode; the vehicle data of the parking charging system (the vehicle data comprises parking duration, vehicle number plate and parking amount) and the visual intercom data of the visual intercom system are transmitted to the database in a wired mode through the exchanger; when the host computer fails, the standby computer is started to work;
when the wired network fails, the video data of the parking lot shot by the monitoring system in the host computer is temporarily uploaded and stored in a storage hard disk of the monitoring system; the host is switched into a 5G module to wirelessly transmit vehicle data of the parking charging system and visual intercom data of the visual intercom system to the database, and the parking lot video data stored in the monitoring system are uploaded to the database in a wired mode after being recovered through a wired network, so that the flow consumption of the 5G module is saved, and the effective operation of the parking lot can be guaranteed; and when the main machine fails, the standby machine is started to work.
