Embodiment Construction

[0019] In terms of physical network composition, the inland RIS system mainly includes mobile ship terminal equipment of model NAVSTAR-II, GPRS / CDMA communication network and system general control center 3, Internet communication network 4 and system sub-control center 5.

[0020] Location data upload service:

[0021] A mobile ship terminal equipment model of NAVSTAR-II is uniformly numbered in the system as AB1001, and its latitude and longitude position (latitude: W38°52.1403′, longitude: E121°31.4837′), time 09:18:52 and speed are collected (12.5 knots), heading (123°).

[0022] This terminal device sends the data packet “@@0x81AB10010x000x2B09:18:52, +3852.1403, +12131.4837, 12.5, 123.00#*” to the system control center 3 .

[0023] The system control center gateway software extracts latitude and longitude, time, speed, heading information and stores them in the database.

[0024] The operating software of the system master control center and sub-control centers connect...

Abstract

An information system of vessel on inland river comprises a system general control centre with CTI system server, multiple system branch control centers with CTI system server and vessel mobile terminals. It features that multiparty all duplex communication can be applied by whole system when rescue is carried out for distress vessel, double way of data transmission between mobile terminal on vessel and control centre can be carried out by the system, public network communication mode can be adapted by the system and simultaneously positioning system can be selected adaptively.

Description

technical field [0001] The invention belongs to the technical field of data communication and computer application, and relates to an inland river ship management and mobile communication system. Background technique [0002] At present, in the management of inland ships, a single very high frequency (VHF) voice communication system is usually used, and only VHF VHF is used to communicate between ships for accident management and coordination. [0003] However, the communication quality, data transmission rate, channel capacity, signal coverage and functions of the VHF VHF voice communication system have certain limitations, and the networking costs, maintenance costs and terminal equipment prices are very expensive, and it is impossible to carry out real-time Monitoring, scheduling, search and rescue and real-time information management of multiple ships. Contents of the invention [0004] The purpose of the present invention is to provide an inland river system that can...
