Public security is the cornerstone of national security and social stability, serving as a vital condition for economic and social development and a fundamental guarantee for people to live and work in peace and contentment. It is a major strategic issue that must be addressed in building a socialist harmonious society. As such, the emergency command system has been actively developed and deployed. However, in practice, it often faces numerous challenges from various aspects. This article aims to explore common issues and provide suggestions on how to avoid them.
With China's growing economic strength, governments at all levels have increasingly invested in the construction of emergency command systems. The core of these systems relies on a data information processing platform, which includes a command center dispatching platform, a transmission network, and front-end information acquisition equipment. Each component plays a critical role. Due to the unpredictable nature of emergencies, different implementation plans must be prepared in advance. As a supplier of wireless mobile video transmission and satellite communication equipment for emergency communication systems, we have gained considerable insight into the construction of emergency command systems and the selection and application of various types of equipment. Here are some recommendations for your reference.
**Emergency Command Systems Should Have Industry Standards**
Currently, the national emergency command platform is managed by the National Emergency Management Office, but provincial and municipal governments have not fully adopted the national model. There are many reasons behind this, including the failure of design units to consider new technologies and products during the initial planning phase. Differences in basic network infrastructure, lack of standardized implementation, complex equipment procurement, and varying technical capabilities among suppliers contribute to the difficulties in using and maintaining the system during emergencies. Establishing mature guidelines and technical standards can ensure the system’s functionality, interoperability, and ease of use. It also helps in integrating with existing networks, managing radio resources, protecting information, and training specialized personnel.
Some relevant departments in China have already formulated or are in the process of developing technical specifications for wireless mobile video transmission systems. Meanwhile, leading enterprises like Huawei are working on industry standardization through certification programs that promote product compatibility and integration.
**Regulating the Emergency Command System Market**
While large-scale national projects require top-tier research institutions, local government projects often lack oversight. Contractors frequently compete based on price rather than quality, leading to unstable systems and poor after-sales service. To address this, setting clear thresholds for contractors and suppliers is essential to protect companies with strong technical capabilities and proper qualifications.
**The Role of Wireless Transmission Systems**
Although wireless mobile video transmission systems occupy a small part of the emergency command support platform, they play a crucial role in critical moments. These systems are used in command vehicles, rescue vehicles, helicopters, drones, and more. Companies with deep understanding of emergency needs develop products that are highly suitable for these applications. For example, multi-carrier modulation technology ensures reliable one-way transmission, reducing interference and improving performance in environments with limited bandwidth and high electromagnetic noise.
**Government Needs to Regulate Radio Product Production and Sales**
China is a major producer of radio products, but their production and sales remain unregulated. Some companies use advanced technologies without adhering to regulations, exceeding frequency bandwidth limits, and even selling non-compliant products. This poses serious risks to emergency operations. Strengthening supervision and enforcing strict compliance with radio regulations is essential to ensure the reliability and safety of emergency communications.
**Future Challenges and Developments**
As the emergency command system evolves, it will rely more on public information networks and 3G/4G/LTE technologies. While 3G systems offer cost-effective solutions, future advancements in high-speed networks will greatly enhance data transmission and processing capabilities. Satellite communication, though currently limited in bandwidth and cost, will see improvements with the development of advanced communication satellites. Front-end equipment, including wireless video and digital trunking systems, will continue to evolve with new technologies, leading to higher-definition video transmission and better overall performance.
In summary, the emergency command system continues to improve alongside technological progress. Strengthening management, establishing standards, and ensuring reliable communication are key to its success. Through years of experience in emergency communications, we strongly believe that the national radio authority and other relevant departments should take more active steps to ensure the smooth and safe operation of the emergency command support system.
