Unified Monitoring Platform

I. Overview

The Unified Monitoring Platform is a software system that provides integrated remote control, management, and remote fault diagnosis for multiple monitoring systems. On-site engineers and headquarters experts see identical system information through the platform, enabling effective front-to-back collaboration, reducing fault resolution time, improving O&M efficiency, and lowering maintenance costs.

II. Platform Components

The Unified Monitoring Platform consists of four parts: subsystem Monitoring Systems, the application bus, the Control Center, and CCS Server.

1. Subsystem Monitoring Systems

Responsible for polling devices, collecting alarms, and reporting to the Control Center.

2. Application Bus

Handles data exchange between subsystem Monitoring Systems and the Control Center.

3. Control Center

Displays status information from each Monitoring System, including alarms, sampled data, and Topology Diagrams, and supports remote parameter configuration.

4、CCS Server

Manages permissions, logs, devices, and online status detection for Monitoring Systems.

III. Platform Features

1. Based on distributed monitoring architecture, it consolidates information from multiple Monitoring Systems into a single interface, giving users full visibility of remote live production system status.
2. Local monitoring and the Control Center connect seamlessly, supporting close front-to-back collaboration during major productions. On-site engineers and Control Center experts can perform remote fault diagnosis, reducing downtime, improving O&M efficiency, and lowering costs.
3. Built on the application transport bus with WAN-optimized architecture, reducing the complexity of cross-network collaboration for remote deployments while ensuring availability and security.
4. Supports connection to OB Van monitoring systems and EFP flyaway kit monitoring systems, enabling seamless and dynamic system access via mobile internet.
5. Provides a complete offline diagnosis mechanism. Even when network access is restricted for security reasons, remote diagnosis and front-to-back collaboration can proceed smoothly.

IV. Platform Advantages

The core of the Unified Monitoring Platform lies in its subsystem Monitoring Systems, whose maturity determines the platform's overall effectiveness. These subsystems include playout/Master Control Room (MCR), studios, OB Vans, satellite uplink vehicles, flyaway kits, and other production and distribution units.

V. Application Scenarios

Primarily suited for daily O&M in large-scale broadcasting projects that span multiple regions, include various production facilities (studios, OB Vans, flyaway kits), and have unevenly distributed technical resources.
The Control Center establishes bus connections with subsystem Monitoring Systems, enabling users to view the status of any Monitoring System (e.g. whether a subsystem is online, whether device or signal anomalies have occurred). It also provides remote fault diagnosis methods and tools, achieving unified supervision and remote O&M assurance across the entire system, thereby reducing staffing requirements and shortening fault resolution time.

Through the Control Center, you can:

1. Query the system status and parameters of each subsystem.
2. View the Topology Diagram of each subsystem.
3. Receive timely feedback on alarm information from each subsystem.
4. Query and compile historical records for each individual subsystem.

VI. Common Issue Solutions

1. Network Topology Plan

Figure 5: Unified Monitoring Platform Network Plan Diagram

The Unified Monitoring Platform supports networking via intranet, 3G/4G mobile networks, and the internet.
Intranet connects co-located subsystems and the Control Center via Switches.
3G/4G mobile networks connect mobile units such as OB Vans to the Control Center.
The internet connects remote subsystems and the Control Center across different locations.

2. Avoiding Single Points of Failure:

For the Unified Monitoring Platform, all modules except the communication bus operate independently and do not share a database, so there is no risk of shared storage failure affecting multiple nodes.
For the communication bus, deploying multiple bus servers eliminates the single point of failure.

VII. Security Design

1. The Monitoring System has a complete authorization framework. Users who are not authenticated and authorized cannot log in or adjust device parameters.
2. The local Monitoring System can disable remote configuration. When remote configuration is disabled, remote clients can only view system status without making changes.
3. Communication between the Control Center client and the bus server supports optional SSL encryption to ensure data transmission security.
4. By system architecture, all modules except the application transport bus are clients, meaning they do not need to bind to a fixed public network address to await remote calls; each module only needs to know the transport bus address. This allows the network addresses of other subsystems to remain hidden, reducing risks from vulnerabilities or management deficiencies. The attack surface is significantly reduced, and with focused protection, the probability of a breach is greatly lowered.
5. The transport bus itself carries no business logic and only transparently forwards payloads. These payloads support encryption, meaning the risks from bus vulnerabilities or errors are greatly reduced.
