With the advancement of technology, the chemical industry has evolved from producing a few inorganic and organic products to a comprehensive production sector with multiple industries and varieties. Many resource-integrated and large-scale chemical enterprises have emerged. Chemical equipment is diverse, and the operating conditions are complex, including different operating pressures and temperatures, and the treated media are often corrosive, flammable, explosive or toxic. Specific equipment must simultaneously meet temperature, pressure and corrosion resistance requirements, and these conditions may be mutually restrictive or frequently change.

Chemical plant explosion accident scene

Chemical enterprises store flammable and explosive hazardous chemicals. Daily fire safety inspections and strengthened management are necessary. Chemical raw materials are flammable and explosive, and production devices may explode due to overheating and overpressure. One must be vigilant against ignition sources, impacts, etc. In case of a fire or explosion, the destructive power is great, the combustion is fast, and the toxicity is strong. It poses a huge threat to people. Firefighting is crucial, but issues such as inadequate communication equipment, uneven network coverage, and insufficient signals affect rescue operations. Therefore, a successful fire suppression or rescue operation cannot be achieved without a safe, efficient, and reliable communication

 command system to ensure the smooth progress of the mission.

Challenges exist

01 Signal instability in complex environments, making it difficult for frontline personnel to obtain communication signals, and the communication signals become weaker the closer to the fire scene.

02 The PDT private network layout has been completed, but there are blind areas in urban basements, tunnels, suburban mountains, and forest areas.

03 There are various communication methods, including DMR, PDT, 4G, ad hoc networks, and satellite communications, and they cannot be effectively integrated.

04 Inconsistent communication networks prevent the rear command center from having a real-time understanding of the fire situation on the scene and from being able to immediately designate response measures and dispatch

additional rescue personnel.

Solution

The scene at the fire site was complex and changing. Fire rescue personnel put on their firefighting and rescue equipment and set up a single-person self-organized network to enter the fire site. Multiple fire rescue personnel formed a communication subnet, transmitting video, voice, and positioning data from the fire site to the on-site command node. At the same time, the video, voice, and positioning data from the underground garage could be transmitted to the command node through a multi-hop relay communication method, effectively ensuring the safety of the firefighters and the actual situation inside the fire site. The drone node can serve as a long-distance transmission relay node, with the high-definition camera on the drone viewing the overall situation. The on-site command node establishes a stable connection with the city command center through satellite links or 4G/5G signals, enabling the transmission and downward delivery of orders from the fire scene to the city command center, and coordinating the operations of various combat units of the departments.

Advantages of the plan

01 It can quickly set up a communication network to ensure rescue efforts when a disaster occurs in a chemical plant with strong destructive power and rapid fire spread.

02 It has functions such as voice communication and video collection, and the video collection from the front line can be transmitted back to the rear command center.

Emergency!

03 The drone acts as an aerial relay link, filling the blind areas and observing the overall situation of the site.

01 Application Case

Resolutely implement the main measures for enterprise safety production

Installation of monitoring cameras and self-organizing network base stations

The wireless self-organizing network communication equipment of Hanxun Technology can achieve real-time monitoring of dangerous areas, covering high-risk areas such as tank areas and near reaction vats, ensuring timely detection and handling of potential threats. In the event of an emergency, our emergency communication equipment can be quickly set up, and the real-time scenes at the site can be transmitted to the command center through high-definition monitoring cameras and self-organizing network base stations, providing strong support for rapid decision-making and emergency handling. This enables managers to remotely observe the maintenance process, thereby ensuring the safety and quality of the operation.
