Description
Technical Field
The invention relates to the technical field of ships, in particular to a timer control method and system and a readable storage medium.
Background
The automatic identification system AIS for ships is an effective navigation aid widely used in modern times. The basic purpose of development is to provide effective collision prevention measures for ships. By installing the AIS equipment on the ship, the staff can visually see the surrounding environment and the running conditions of nearby ships. The monitoring system can perform early warning on the possible dangerous condition according to the course, the speed and other information of the ship and the peripheral ships.
The AIS system described above is designed with self-centric monitoring requirements. At a higher level, an inspection from a global perspective is required, and a role switch between global and self is required. The distributed service involved in the scheme is a technical implementation scheme for the requirement. This service-borne function 1) is monitored centrally on the selected vessel. 2) Global ship monitoring. The first function is embodied in AIS equipment, but workers cannot go to each ship at any time to feel and monitor. The second function is more mature products, such as ship communication network. To meet the functional requirements of condition 1), an efficient data service is required for support.
To meet the high performance access requirements, the data service must provide both computing and memory capabilities. 1) And calculating and generating various early warning data by taking each ship as a center. 2) And storing the early warning and state data of each ship. A single server has difficulty supporting both of the above capability requirements, especially computing power.
Both of the above problems are relatively easy to solve by distributed service design. And (4) taking the region as a division rule of the ship object, and managing the ships belonging to different servers in different regions. Computing and storage capabilities are expanded and performance requirements are met.
In the implementation logic of the ship early warning function, the use of a timer is generally involved, such as the timing detection of the operation condition of a peripheral ship, the warning without leaving a target ship for a long time, and the like. Conventional timing managers have their lifecycle and scope subordinate to a single service. This means that the timer will be disabled after the ship object has changed its home server due to navigation.
In the existing solution, after the service object generates the service migration, the related timer data is migrated, and the timer is created again. The design is complex and the realization is not uniform.

Fig. 8 is a third schematic block diagram of a timer control system 800 in accordance with an embodiment of the present invention. The timer control system 800 includes:
a receiving unit 802, configured to receive timer information sent by a service object, where the timer information includes an information type of the timer information;
a determining unit 804, configured to determine whether the information type is service object migration information;
a migration unit 806, configured to determine, when the determination result is yes, a network address of the service server after the migration of the service object, and send the network address and the timer information to the timer server;
and a forwarding unit 808, configured to forward the timer information to the timer server when the determination result is negative.
The timer control system 800 provided in this embodiment is used for a timer agent. The timer proxy is a bridge for the business object and the timer server. When the receiving unit 802 receives the timer information sent by the service object, the determining unit 804 determines whether the information type of the timer information is the service object migration information, if so, the migrating unit 806 needs to determine the network address of the service server after the service object migration, and sends the network address and the timer information to the timer server. Otherwise, the timer information does not need to be processed, and the timer information is directly forwarded to the timer server through the forwarding unit 808. Therefore, for the service object, the network address of the service server does not need to be considered when the service object is migrated, and for the timer agent, the information type only needs to be judged once without other data processing, so that the timing processing efficiency can be improved, and network resources are saved.
Specifically, the timer proxy may be deployed on a service server, and when a service object is migrated to the service server, the network address of the service server is the network address of the service server after the migration of the service object occurs.
Example nine
Fig. 9 is a fourth schematic block diagram of a timer control system 900 according to an embodiment of the present invention. The timer control system 900 includes:
a generating unit 902, configured to generate timer information according to the service operation logic;
a sending unit 904, configured to send the timer information to the timer agent;
the timer information carries an information type identifier of the timer information, and the timer information includes any one of the following items or a combination thereof: service object ID, timer ID, adding or deleting timing task information, and time information.
The timer control system 900 provided in this embodiment is used for business objects. The creation of the timer is triggered automatically by the business object entirely according to the run logic, and the timing time is also determined by the business object. The timer server only needs to monitor the timing time according to the needs of the service object and inform the timer server that the timing time is up at the appointed time point. When the service object is migrated, the network addresses before and after the migration do not need to be considered, the network addresses only need to be processed by the timer agent, and the timer agent can acquire the network address of the service server after the migration. When a business object needs to add or delete a timing task, the timer ID and the corresponding requirement information of the added and deleted tasks are sent to the timer proxy, and the timer proxy interacts with the timer server so that the timer server controls the timing requirement of the timer server.
Example ten
The present embodiment provides a readable storage medium on which a program or instructions are stored, which when executed by a processor implement the steps of the timer control method as in the above embodiments.
The present embodiment proposes a readable storage medium, which stores a program or instructions that, when executed, can implement the steps of the timer control method according to the above embodiment. Therefore, all the advantages of the timer control method are achieved, and are not discussed in detail here.
EXAMPLE eleven
In this embodiment, as shown in fig. 10, a system architecture of the Timer control system includes three parts, namely, a Timer manager (i.e., a Timer server), a Proxy manager (i.e., an agent manager), and a TimerProxy client (i.e., a Timer agent).
The Proxy manager manages timer agents for a plurality of traffic servers. In order to ensure the message transmission efficiency, a classic Server-Client mode is adopted, and the manager keeps long connection with the Proxy Client of the service Server. The network Timer manager implements the conventional Timer method, a Timer wheel implementation, on the server side. Unlike a traditional timer manager, this manager maintains the user (business object) id of the timer and its proxy address. The TimerProxy client is the bridge for information interaction. The business object can conveniently use the Timer through the Proxy, just like using the traditional local Timer manager. When the TimerProxy processes the timing notification of the network timer, the TimerProxy finds the service object reference according to the service object ID attached in the notification, and triggers the timer task.
When the service server is started, the service server notifies and registers the local TimerProxy to the network Timer manager. The business object adds and deletes the timing task to the network Timer service through the local TimerProxy, and the business object informs the network Timer manager through the business object when the migration is generated among the business servers. As shown in FIG. 11, business object B is migrated from Server A to Server B. The interaction of the business objects with the network timing manager is an asynchronous manner. The Timer manager sends a timing notification message to the service object after detecting the Timer trigger. The business object needs to have the capability to process asynchronous messages, respond to and process timing notifications in the logic that processes asynchronous messages. The timings of adding, deleting, and responding to the timing notice are shown in fig. 12 and 13.
The network timing manager uses the flow:
1) the timer agent is configured with a network timer network address.
2) A timer agent is started.
3) And each service object acquires a timer proxy and performs the addition and deletion of the timer and the migration work of the service object.
4) Each business object responds to the timing notice and processes the timing task.
When the business system rule is complex, logic for adding or deleting the timer again exists in the processing logic of the timing task. When the traditional timing manager processes the logic, the condition of reference access exception exists.
The timer manager has a plurality of timers in slot 2, which are organized in a data structure in the form of a list, such as list or vector. When time goes to slot 2, the timing manager needs to traverse this list, triggering the timer. If the logic for adding or deleting the timer again exists in the timer callback processing logic, the reference address of the list element is necessarily changed. At this time, the pointer currently used to traverse the list cannot be used, otherwise there is a serious problem of access exception.
The implementation of this embodiment is that the network timing server processes the timer information by using an asynchronous processing mechanism, and the operations of adding and deleting the timer again in the logic triggered by the timer are only performed in the processing of the next time slice of the network timing server, and the access of the current timer list is not affected.
The timer control method and the timer control system provided by the embodiment can achieve the following beneficial technical effects:
1) the network timing manager exists independently of the business service, so that the resource loss of the business service is reduced;
2) the asynchronous implementation mode of the network timer naturally solves the problem that the timer is added/removed again in the timing event processing logic to cause the abnormality of the timing manager;
3) the traditional timer can be developed and realized again only in the system of the traditional timer, and the scheme provides the capability of directly providing timing service for a third party.
