Abstract

The invention discloses a target object access method, device and system and computer equipment, and the method comprises the steps: obtaining geographical location information broadcasted by each target object; grouping the target objects based on the geographical location information to obtain grouping information and access window information, the access window information including a plurality of access time slots; broadcasting the grouping information and the access window information; obtaining an access resource request message fed back by each target object based on the grouping information and the access window information; and allocating access resources of each target object based on the access resource request message, generating a resource allocation message, and respectively sending the resource allocation message to each target object, so that each target object selects respective corresponding access time slot for access based on the resource allocation message.

Description

technical field [0001] The present invention relates to the technical field of target object communication, in particular to a target object access method, device, system and computer equipment. Background technique [0002] With the continuous development of the marine economy industry, the number of target objects continues to increase, and the types of maritime communication services show a diversified development trend. The original maritime communication system based on the Automatic Identification System (AIS) of the target object can no longer meet the requirements. The development needs of future maritime communications. The VHF Data Exchange System (VDES system for short) is an important part of the future maritime communication system. On the basis of the original AIS target object automatic identification system, the VDES system adds two parts: Application Specific Message (ASM) and VHF DataExchange (VDE) to provide higher data transmission. rate. [0003] VDE ...
