Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0046] The method for querying the location information of water objects provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 101 can read or write data from the cache database 102 . The cache database 102 can also communicate with the Kafka message queue server through the network to obtain the data in the Kafka message queue; wherein, the terminal 102 can be but not limited to various personal computers, notebook computers, smart phones, tablet computers and Portable wearable device.

The invention relates to an overwater target position information query method, system and device, computer equipment and a storage medium. According to the method and the device, the position parameter of the water target in the cache database can be accurately updated in real time, so that the position parameter of the water target stored in the cache database is always kept in the latest state. The method comprises the following steps: acquiring a to-be-stored position parameter of an observed water target from a Kaffilian message queue, wherein the to-be-stored position parameter comprises a target identification code and a to-be-stored timestamp; when the existing timestamp corresponding to the target identification code is stored in the cache database, if the to-be-stored timestamp is later than the existing timestamp, replacing the position parameter of the stored target identification code with the to-be-stored position parameter, and taking the to-be-stored position parameter as the latest position parameter; and in response to a target position query instruction, calling a target query function to obtain the latest position parameter of the to-be-queried target from the cache database.
Description
technical field [0001] The present application relates to the technical field of water target monitoring, in particular to a method, system, device, computer equipment and storage medium for querying position information of water targets. Background technique [0002] With the development of maritime industry and national defense technology, the tracking and management of maritime targets has become particularly important. At present, the precise positioning of moving targets on water has been realized, and the real-time position of the targets on the water can be obtained through the positioning system. The query of location still has the problem of low real-time performance. Contents of the invention [0003] Based on this, it is necessary to provide a method, system, device, computer equipment and storage medium for inquiring about the location information of water targets to address the above technical problems. [0004] A method for inquiring about location informat...
