Solution of Zhejiang Kaichi Shortwave Visual Communication Management System

1. Overview

As an important part of civil air defense combat readiness communication, short-wave communication system is attached great importance to short-wave communication by civil air defense units at all levels. Daily training, exercises, training, assessment and competition around short-wave communication subjects have been institutionalized and normalized in the civil air defense system, laying a solid foundation for dealing with major disasters and national defense combat readiness communication support. However, due to the particularity of short-wave communication, the application and management of short-wave communication system for a long time still use the method of decades ago. With the progress of science and technology in recent years, independent frequency selection short-wave radio has gradually become the mainstream of civil air defense short-wave system, and the new functions of independent frequency selection radio provide a good foundation for exploring and creating new methods of short-wave applications.

At present, the construction of autonomous frequency selection short-wave communication system for civil air defense in various provinces and cities is in progress, and some provinces and cities have gradually become a network. In this case, the informatization degree of the autonomous frequency selection communication system is further improved. Through the construction of network, data, visualization and refinement, the fixed station, mobile station, backpack station and other terminal equipment of short-wave radio station, which were originally fighting for each other, are integrated into a network for unified management, it has become an urgent need to match and adapt the construction of the existing short-wave communication system to the requirements of the overall construction of civil air defense information. At the same time, the construction plan provides a realistic and feasible decision-making option and support for the 14th Five-Year Plan of the information construction of the short-wave communication system of the civil air defense system.

Zhejiang Kaichi shortwave visualization management system belongs to Kaichi multi-network system fusion scheduling management system, so as to solve the short-wave wireless communication related business. The system connects the independent frequency selection short-wave base stations of various cities to the civil air defense network through the short-wave gateway, realizing the unified management and visual application of the short-wave radio equipment of the civil air defense departments at all levels. Users can not only use the traditional mode to operate and use the shortwave radio station, but also display the distribution information, radio station status and wireless communication link quality of each station of the whole network shortwave communication system in real time on the computer and large screen through the application software. While controlling the radio station, the functions of automatic recording, archiving, statistical analysis and management of the data in the whole process of daily training, duty, exercise and exercise are realized. The short-wave visual communication management system innovates the traditional short-wave radio application and management concept, and expands the new application mode and application scenario. The system adopts full IP backbone architecture and SIP standard communication protocol. The system design conforms to the development direction of network, data, intelligence and visualization of information equipment.

2. System Design

Chart 2 has a wireless communication network architecture design.

The system vertically adopts the hierarchical management structure of provinces, cities and counties (districts), and each level has different access rights for equipment integration access, visual situation monitoring and scheduling management according to planning and design. The horizontal is divided into an IP network base station built by an integrated scheduling server, an access gateway, a large screen, and an independent frequency selection short-wave radio station, and a mobile station composed of an independent frequency selection short-wave backload station and an independent frequency selection short-wave vehicle station.

Through the short-wave radio access gateway, the short-wave autonomous frequency selection radio station is virtualized into a SIP terminal with command interaction.

3. System composition

The system mainly includes shortwave visualization scheduling subsystem and shortwave visualization management subsystem. The short-wave visual scheduling subsystem mainly realizes short-wave radio station scheduling and operation-related services, such as short-wave radio station detection, call, tracking, short message, group detection, group short message and other related operations, as well as short-wave radio station real-time status, situation distribution and other more practical functions for end users, which can effectively assist in the management and use of short-wave radio stations and improve the communication rate of short-wave communication. The shortwave visualization management subsystem mainly realizes shortwave daily management related businesses, such as daily duty, exercises, operation and maintenance management, assessment management, etc. At the same time, it also collects data during the use of shortwave radio stations, supports retrieval and analysis of key data information such as detection, call, short message and tracking, and provides alarms for abnormal situations such as shortwave radio station fault information, power information and voice quality.

Short Wave Access

The access layer virtualizes the shortwave autonomous frequency selection radio into a SIP terminal with command interaction to access the system through the shortwave radio access gateway.

Short wave situation display

The location information of each short-wave radio station is managed through the geographic information system, and the real-time situation distribution and real-time status information display of short-wave radio station are realized with the help of the real-time data reporting function of short-wave gateway. Such as radio station online, occupied, offline, etc.

Shortwave Radio Dispatch

It is supported to set the short-wave gateway radio station (there is a short-wave gateway at the short-wave radio station end) as the default radio station. When the communication of the local radio station is poor, the short-wave radio station with good communication is used to communicate with the target radio station to provide the resource utilization rate and communication rate of the short-wave radio station.

Probe, Call, SMS

Through the deputy handle or browser operation, can be realized in the case of far away from the radio station in the system of any short-wave radio detection, call and short message and other functions.

-Tracing, Trajectory

Through direct operation on the browser side, it supports real-time tracking and reporting of real-time position information and link information of short-wave electricity connected to Beidou in motion, and saves process data, which is convenient for users to playback tracks.
