背景分析
监狱通信系统需满足高安全性、强管理性和应急响应三大核心需求。当前主流方案存在以下局限性：
常规中转系统：缺乏分级调度能力，无法实现多警种独立通信
公网虚拟专网：存在外部通信风险，难以保障信息安全
共性缺陷：缺少应急指挥通道，管理功能薄弱
系统功能需求
安全隔离通信：构建独立无线专网，物理隔离公网通信
智能分组调度：支持跨区域/跨职能的多级分组管理（监区/岗位/职级）
应急响应体系：突发事件时自动激活优先通信通道
指挥层级架构：实现"管理局-监狱-监区"三级联动通信
解决方案设计
方案一：单区单基站系统
适用场景：县域级独立监狱（覆盖半径≤3km）
技术特性：
采用TDMA时分多址技术
支持500+终端并发通信
冗余备份设计（断电续航≥8h）
方案二：单区多基站系统
适用场景：省会城市监狱群
核心优势：
智能负载均衡（动态分配基站资源）
故障自动切换（中心链路中断时保持70%通信能力）
无缝漫游（切换延迟＜200ms）
方案三：全省联网系统
架构设计：
管理中心：部署SIP软交换平台
传输网络：基于MPLS-VPN构建专用骨干网
终端管理：支持远程固件升级与权限配置
管理功能：
实时监控各监狱通信状态
跨监狱组呼建立时间＜1s
操作日志留存≥180天
Essence of Prison Wireless Command and Dispatch Solution
Background: Prison communication requires high confidentiality and robust management capabilities, yet existing systems struggle to meet the demands of complex environments for group dispatching, emergency calls, and security needs. In light of these practical communication requirements within prisons, our company has developed a prison trunking wireless command and dispatch solution.
Solution Overview:
- Single-Zone Single-Base Station: Ideal for small prisons, ensuring comprehensive wireless communication coverage throughout the prison while maintaining secure and independent voice communication.
- Single-Zone Multi-Base Station: Aimed at multi-prison regions, interconnecting multiple base stations with a control center to achieve broader coverage and flexible dispatching capabilities.
- Provincial Networking: Connecting various prison trunking systems across the province to facilitate unified command and dispatch, as well as automatic radio roaming throughout the province.
Features:
- High Confidentiality: Terminal access requires identity verification, and voice encryption is employed to prevent unauthorized eavesdropping.
- Flexible Management: Enables flexible grouping, supports rapid temporary grouping, grants high-level privileges to the dispatch console, and boasts comprehensive emergency response plans.
- Comprehensive Needs Fulfillment: Addresses both routine and emergency communication issues, including independent voice communication, interference reduction, channel optimization, multi-level grouping, and unified command, among others.
