Detailed Description
The technical solution of the present invention will be described in further detail with reference to specific embodiments.
An airport data exchange application system comprises a bus service system (short for data exchange bus airport application) and at least one access system, wherein each access system is respectively connected with the bus service system. As shown in fig. 2, the access system may be a flight display system, a production operations system, a security check system, a broadcast system, a baggage system, and other related systems. The access system A sends the message to the bus service system, which forwards the message to the access system B needing the message, therefore, the data exchange with other access systems can be realized only by connecting each access system with the bus service system through one line.
The airport data exchange application system is provided with a bus service system, and provides data exchange for all access systems needing data exchange in an airport in a message mode. Each access system is connected with the bus service system through a line, the access system only needs to send the message to the bus service system, and the bus service system forwards the message to a receiving queue of the access system needing the message, so that the line is simplified, and the message response time is reduced.
The bus service system comprises an IB server, a database, a program package set for each access system, a management interface and a monitoring system. An IB (Integration Bus) server is used as a data exchange middleware. The database is used for storing a message routing relationship, wherein the stored message routing relationship refers to a corresponding relationship in which the access system A is associated with a specific access system B through a specific message. The management interface is used for changing message routing relation configuration and displaying a monitored web system. The monitoring system is used for monitoring each message circulation process in the bus service system, log information is recorded in a file or a database at each step in the message circulation process, and the monitoring system reads the log information to monitor the whole message circulation process.
In the bus service system, each access system is provided with a program packet, the program packet comprises a sending queue, a receiving queue and a heartbeat generator of the access system, and each access system is respectively provided with a corresponding and unique sending queue and a unique receiving queue which are respectively used for sending messages and receiving messages. Thus, the access system exchanges data with the bus server via the program package.
According to the method and the device, the sending method of the sending queue and the receiving method of the receiving queue are packaged into the program package through the WebService technology, and the user is limited to only perform message receiving and sending operations. The access system can directly call the two methods of sending and receiving after introducing the program package, for the user, only the two methods of sending and receiving can be seen, the automatic confirmation of the message, the monitoring of the message and the like are encapsulated in the background and automatically called, and the information exchange between the access system and the bus service system is greatly facilitated. The user needs to log in before using the WebService and the identity of the user is verified.
The heartbeat generator is used for monitoring the connection state of the access system and the bus service system. Specifically, after the access system is subjected to login verification operation, the access system is connected with the bus service system through the program package, the heartbeat generator is started immediately, the heartbeat generator continuously sends heartbeat signals to the IB server, and the monitoring system monitors the heartbeat signals by reading logs. If the monitoring system finds that the IB server does not receive the heartbeat signal for a long time, the access system can be judged to be disconnected with the bus service system, the monitoring system gives an alarm in time to remind, and operation and maintenance personnel can conveniently overhaul. The alarm form includes but is not limited to the mode of web page pop-up, short message and mail.
The airport data exchange application system has the following characteristics:
the method has the characteristics that: the monitoring function, every step of the message circulation process in the bus service system can record the log information into a file or a database, and the monitoring system can read the log information, so that each node can trace and circulate.
The method has the following characteristics: the automatic heartbeat function is added in a program package, a heartbeat generator continuously sends heartbeat signals to an IB server of the bus service system for monitoring the connection state of the access system, and if the access system is disconnected due to network and other reasons, timely alarming and reminding are carried out, so that operation and maintenance personnel can conveniently overhaul.
The characteristics are three: the bus service system copies a plurality of copies and puts the copies into a receiving queue of an access system B which needs to receive the message after receiving the message sent by the access system A, thereby improving the message receiving speed of the access system B, so that a user does not have a query process when receiving the message, the user can quickly acquire the message, the user experience is quickly improved, and the speed is much higher than that of reading and diffusing. The method has the advantages that the user is prepared with the messages needed by the user in advance, the workload of the bus service system is increased by doing so, the efficiency of the user is increased, the message routing relation is recorded into the database in advance, and the user can know the messages needed by the access system in advance
It should be noted that the difference between the "read flooding" and the "write flooding" is that the "read flooding" is to actively check whether there is a message required by an access system in a transmission queue of each access system when the access system requests to receive the message, and then forward the message to the access system, as shown in fig. 3. The "write flood" is the distribution of the access system's required messages into the access system's receive queue before the access system goes to the receiving system, as in fig. 4. The advance preparation is that when a message is sent into the bus service system, the IB server of the bus service system immediately parses and allocates the message to the receiving queue of the access system which needs the message, as shown in FIG. 5.
The application also provides an airport data exchange application method, as shown in fig. 6, the specific steps are as follows:
s101, an access system A sends a message through a sending queue corresponding to the access system A;
s102, the IB server reads the message in the sending queue, judges whether the message designates an access system B (possibly a plurality of access systems B), if yes, the step S103 is executed, otherwise, the step S104 is executed;
s103, the IB server directly sends the message to a receiving queue of the specified access system B without passing through a database;
s104, the IB server searches an access system B needing the message from the message routing relation of the database, and places the message into a receiving queue of the access system B;
s105, the IB server stores the message in a library and records a log;
s106, a message automatic confirmation program, wherein the access system B receives the message and sends an ACK to the IB server, the IB server judges whether the ACK is received, if so, the step S107 is executed, and if not, the step S108 is executed;
s107, the IB server returns a response to the access system A;
and S108, the IB server informs the access system A to start a message retransmission program.
In step S106, ACK is short for english ACK, which means that the access system B notifies that the message has been received, and is a certificate for confirming that the message has been received to the IB server, and belongs to a message automatic confirmation function of the airport data exchange application system. If the IB server does not receive the ACK returned by the access system B, indicating that the access system B does not receive the message, the access system will receive the message that is not received again the next time the access system receives the message. As shown in fig. 7, the specific steps of the access system a to start the message retransmission procedure are as follows:
s801, an access system B sends a request message, the access system B calls a message receiving service, an IB server confirms whether the access system B has an unacknowledged message, if yes, the step S802 is executed, otherwise, the step S803 is executed;
s802, after the database query, if the access system B receives the message, does not confirm the message and does not expire and needs to retransmit the message, the message needing to retransmit is stored in the database, and the step S804 is entered;
s803, the IB server checks whether there is a new message in the receiving queue of the access system B (the access system a to which the new message refers sends the new message out), and if there is no new message, the process goes to step S804; if the new message exists, reading out the new message, and judging whether the message is expired, if the message is expired, directly discarding the message, and if the message is not expired, entering step S804;
s804 splices (splices and loads, or merges) the message to be retransmitted in S802 and the new message in the queue in S803, and then returns the spliced message to the access system B.
In the above message retransmission procedure, whether the message is expired is determined by the expiration time configured in the message type, the message transmission time, and the current time.
The message automatic retransmission function can ensure that each message is accurately transmitted to a required access system, and the system can timely find missed messages and perform automatic retransmission operation just by comprehensively monitoring the whole process due to the powerful monitoring function of the system.
The airport data exchange application system and the airport data exchange application method are beneficial for operation and maintenance personnel to find problems in time, and program packages are arranged for each access system in the bus service system, so that the self-repairing capability of the access system is enhanced, the message circulation process is very reliable, the login verification and automatic heartbeat functions are added, the user right of the access system is protected, and the state of the access system is monitored. The WebService is used for packaging and receiving messages, and an automatic confirmation function and an automatic retransmission function are packaged in the WebService, so that a queue is protected, most importantly, heartbeat detection, automatic retransmission and the like are automatically completed by a bus service system, and an access system does not need to care about the operations and calls a receiving and sending interface to directly receive and send the messages.
