In the “Twelfth Five-Year” Development Plan for China’s Security Industry, middleware technology is listed as one of the key application areas for the development of security technology. The plan pointed out that it is necessary to vigorously develop middleware products, realize the association, integration, collaboration, interaction and on-demand services between various information resources, solve the problems of interoperability, reliability and security between different systems, and realize application The transformation of the system from hardware as the core to software as the core. Middleware technology will be widely used in various security application software and systems, especially in industries with complex security application systems such as prisons and detention centers.
Problems facing prison security construction
The prison security system is an important part of the prison informatization construction. The system plays an important role in supervising the reform of prisoners and preventing the occurrence of emergencies. However, the application development and construction of prison security management software and platforms still face many challenges. The problems that need to be solved urgently are mainly reflected in the following aspects.
1. There are many types of security subsystems, which cannot be managed uniformly. As we all know, in the prison security application system, all aspects of the security system are involved. In addition to the video surveillance, perimeter defense, alarm, public broadcasting and other systems commonly used in other industry applications, it also includes application systems unique to prison business. , such as meeting system, intercom, AB door, high-voltage power grid, etc. These systems have independent management systems. In the process of using, operators need to log in to different systems for operation and maintenance, which cannot be managed in a unified manner, resulting in cumbersome operation procedures and difficult maintenance.
2. Each subsystem is independent of each other, forming an information island. Since each subsystem is usually produced and developed by different manufacturers, the sharing and distribution of system information are not taken into consideration when designing the system and database. As a result, the synchronization of information update is poor, which affects the consistency and correctness of data. Information resources are dismantled and scattered with a lot of redundancy. The efficiency of information use and management is low, and the unity is lost. A typical example is that in the system, it is necessary to enter the criminal information into the RFID personnel positioning system for personnel positioning management, and also need to enter the same information into the criminal information management system for daily management, RFID personnel positioning system and criminal information. Each management system has become an information island, and information cannot be shared and interconnected.
3. There is no standard system interface, and it is difficult to expand business functions. In the prison security system, the system principle and structure of each subsystem are different, involving all aspects of video, communication, network and other technologies. There is no general standard in the industry, so the standards that manufacturers follow when designing and producing products are not uniform. , resulting in inconsistent interfaces between different types of products, even the same type of product interface will not be unified. For example, in a video surveillance system, if a brand of video encoding equipment is selected at the front end, then under normal circumstances, when the monitoring center needs to decode the video and output it to the large screen, it must also choose the same brand of video decoding equipment. The inconsistency of the system interface makes the expansion of new business functions greatly restricted. For example, when building a prison emergency command system, the superior command center wants to know the scene situation, so it needs to call video surveillance in the video conference system. However, because the interface standards of the video conference system and the video monitoring system are not unified and cannot be interconnected, it is difficult to realize this function.
middlewareApplication of technology in prison security
The application of middleware technology can well solve the above problems. Like the OpenVone audio and video middleware launched in the industry, it can abstract the hardware and software in the security system, so that the upper-layer software does not have to pay too much attention to the underlying hardware and complex network protocols, and forms various standardized services and components, software developers can These services and components can be used arbitrarily, so that application systems can be developed quickly according to actual business requirements. The modules of the middleware can be upgraded or optimized individually, so that various existing hardware devices can be integrated into the security system through the device access layer.
OpenVone audio and video middleware adopts a hierarchical service-oriented (SOA) open architecture, which consists of four different functional layers: device access layer, network communication layer, platform basic service layer, and application service component layer. A basic platform integrating security equipment management, security information exchange, and security business integration (see Figure 1).
At the device access layer, OpenVone audio and video middleware follows the standardization of interfaces and protocols to realize the standardization of communication protocols, network transmission, device access, service expansion, and audio and video codecs. Access protocol interface, realize the access of various prison security subsystems such as video surveillance, perimeter defense, alarm, public broadcasting, meeting system, intercom, AB door, high-voltage power grid, etc., in order to achieve unified management of each subsystem Lay the foundation.
In the network communication layer, OpenVone realizes the cascading and management of multi-level central servers, and builds a highway for the distribution and transmission of system information. The network communication layer not only provides the control command transmission service for the system, but also can be used as the data transmission platform of the business system. Developers can realize the development of a large-scale distributed prison security management system without caring about the network link and management of the system.
The platform basic service layer is the core of OpenVone audio and video middleware, which can provide alarm and event management services, video storage and retrieval services, video exchange and forwarding services, device management and control services, data storage and access services, user and rights management services , system operation monitoring services, system maintenance and management services, etc., the core of the prison security management system can be built using the platform basic service layer. Since these services are managed, upgraded, and released in a unified manner, all kinds of equipment information, personnel information, alarm information, etc. are collected, classified, stored, transmitted and analyzed in a unified manner, which solves the information islands that existed in the prison security system in the past. problem. On the other hand, unified management also ensures the stability and maintainability of the entire system.
The application service component layer adopts plug-in development technology, including image display, PTZ control, permission management, alarm linkage, video wall control and other components. All components can be “plug and play”, software developers can choose different components to combine according to specific business needs, and quickly build various applications. At the same time, the components can be added and deleted arbitrarily, thus realizing the arbitrary expansion of the functions of the prison security management system.
The industry has successfully developed a prison security defense and emergency command platform based on OpenVone audio and video middleware, which can integrate perimeter defense, video surveillance, alarm, power grid, AB gate, access control, patrol, intercom, public broadcasting, meeting, etc. This system realizes the interconnection and mutual control and information fusion and sharing among the systems.
The platform can conduct real-time video monitoring, behavior analysis, audio recording and video recording of important places such as prison perimeters, prison buildings, confinement rooms, practice venues, and prison hospitals. It has established an effective prevention and control system for the entire prison. The platform has been successfully applied to prisons and detention centers in Henan, Hubei, Henan and other provinces.
