When the fire monitoring and early warning equipment in the actual scenes detects a dangerous situation, the corresponding fire monitoring and early warning equipment in the fire accident emergency command platform is highlighted.

8. The shipbuilding fire accident emergency response system according to claim 6, characterized in that: The gas leakage and fire monitoring and early warning subsystem based on wireless networking includes smoke sensors, temperature sensors, gas concentration monitors, manual alarm buttons and sound and light alarms; the smoke sensors, temperature sensors, gas concentration monitors and manual alarm buttons are all wireless monitoring equipment that send early warning information via wireless communication; when the gas leakage and fire monitoring and early warning subsystem based on wireless networking detects that the environmental factors exceed the specified threshold, the alarm information is transmitted to the fire accident emergency command platform via wireless transmission, and the fire accident emergency command platform pushes the danger information to the person in charge of key areas of the ship under construction via text messages and voice simultaneously.

9. The shipbuilding fire accident emergency response system according to claim 6, characterized in that: The real-time counting subsystem for the number of operating personnel is used to track and count the distribution of personnel in key areas of the ship under construction in real time; The emergency resource dynamic management subsystem includes an emergency plan library, an emergency personnel management library and an emergency material management library; the emergency plan library includes comprehensive emergency plans, special emergency plans and on-site disposal plans; the emergency personnel management library includes the emergency command center personnel library, emergency rescue team personnel library, fire brigade and single ship project team member library; the emergency material management library includes company-level emergency materials and single ship project emergency materials; The remote emergency command subsystem includes an evacuation path planning module and a remote video connection module; the evacuation path planning module selects the best evacuation path based on the shortest path principle to avoid the fire source; the remote video connection module uses a wireless networking method to connect the fire accident emergency command platform and the accident site; The fire accident emergency command platform obtains the real-time location information of fire trucks and rescue vehicles through the vehicle positioning system, displays the information of emergency personnel and emergency materials, dynamically calls emergency personnel and emergency materials according to the monitored alarm information and personnel distribution, and plans the evacuation escape route at the same time, and sends the shortest evacuation route as the optimal evacuation route indication to the two-way emergency evacuation signs deployed in key areas of ships under construction. According to the direction of the optimal evacuation route, the left arrow or the right arrow of the two-way emergency evacuation sign is lit.

10. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the computer program is executed by a processor, the steps of the method according to any one of claims 1 to 5 are implemented.
