After the earthquake that struck Japan on March 11, 2011 and caused a tsunami that caused a radiation accident at the Fukushima nuclear power plant, the safety issues related to nuclear power plants received much attention. However, with regard to the occurrence of radiation accidents, the issue of how to quickly evacuate the people in the affected areas near the accident site has not received much attention for a long time. As long as there is a nuclear power plant, the possibility of radiation accidents due to damage to nuclear power plants cannot be ignored. Once a radiation accident occurs, the first thing to face is how to help people escape the scope of the accident and reduce casualties. As far as the existing mechanism is concerned, it seems that only local police can help evacuate and guide the direction of escape. However, the area affected by such an accident is very large, and the limited police manpower cannot be evacuated to a large number of people in time, let alone guide them. Quickly escape to places of refuge everywhere. Therefore, it is foreseeable that most people cannot escape to refuge places in time, and panicked people may be blocked on the road or lost in the process of escape, thus missing the opportunity to escape.

The first figure is a block diagram of a preferred embodiment of the present invention.

The second figure is a flow chart showing the operation of the servo device in the preferred embodiment.

The system block diagram of the first diagram shows a preferred embodiment of the present invention, which discloses an accident evacuation guidance system that is particularly suitable for radiation accidents, such as radiation leakage accidents caused by nuclear power plant explosions. But not limited to this. The system includes a servo device 2 that is linked via a network 1 and an electronic device 3 carried by the user. The servo device 2 includes one or more computers, preferably a server class computer. More preferably, the servo device 2 further includes a short message transmitting device connected to the aforementioned computer. The electronic device 3 preferably wirelessly links the network 1, which can be a smart phone, a tablet, a notebook brain or other portable smart electronic device. In this example, the electronic device 3 is a smart phone with GPS positioning function.

The server device 2 is installed with a service program. The electronic device 3 is equipped with an application program. Under such a configuration, the system of the present invention can operate to complete the following steps: a) estimating an accident impact range based on accident information and weather information; b) The scope of the accident and the information of the evacuation site, screening out an appropriate evacuation site; c) constructing an optimal evacuation route based on the geographical location of the current location of the user and the geographical location of the evacuation site; and d) The optimized evacuation route directs the user to the evacuation site.

In step a, the accident information includes the location of the accident, but not limited to this. Taking radiation accidents as an example, the accident information includes the location of the radiation accident and the radiation coverage, and preferably the content of harmful substances. When the accident occurs, the official will release it through various channels. For example, the funds can be obtained from the official website of the Atomic Energy Commission of the Executive Yuan of China. News.

The weather information includes weather information, wind speed, rainfall situation, fogging situation, etc., and the weather information, preferably including the prediction of the information, but not limited thereto. This information can be obtained from the official website of the Central Meteorological Administration of China. In the case of a radiation accident, the wind direction and the wind speed affect the diffusion speed and the diffusion direction of the radiation. Therefore, in step a, the diffusion speed and the diffusion direction of the radiation are calculated mainly according to the wind direction and the wind speed in the weather information. And estimate the area affected by the radiation (ie, the scope of the accident) based on the calculation results. However, if the accident information has already included the scope of the accident, such as the official estimate of the scope of the accident, then the a step can be omitted.

The evacuation location information in the step b includes the names and geographical locations of the plurality of evacuation sites (locations), but is not limited thereto. These evacuation sites can be used for emergency evacuation by local people at the time of the accident. They are usually arranged and announced by the government before the accident, but may be decided and announced after the accident. In addition, the appropriate refuge site selected through the b-step refers to a site that is completely unaffected by the accident or has a slight impact or an underground refuge with radiation protection. In the case of a radiation accident, the appropriate evacuation sites are preferably outside the range of the estimated radiation accident, but may also be within the range. For example, if the escape time of a person close to the location of a radiation accident is estimated to be only half an hour based on the content of harmful substances (it may be lost due to excessive exposure to harmful substances), it is reasonable to find out half. Instead of finding an evacuation site outside the reach of the radiation incident, the evacuation site can be reached within an hour.

In step c, the geographic location of the user's current location may be obtained from an electronic device (eg, a GPS-enabled smart phone) carried by the user. The optimized refuge route can be generated in conjunction with existing route planning techniques, such as the use of Google Maps API components. Alternatively, a combination of satellite positioning system (GPS) and geographic information system (GIS) techniques can be used to generate the optimized evacuation route. The best refuge route may be a shortest route between the current location of the user and the refuge site, with the possible exception. Further, in a preferred example, the c step is also constructed based on road traffic condition information. Out of the best refuge route, so that the best refuge route avoids the road sections that have been banned and traffic congestion. In this case, the best refuge route is the fastest route to the refuge site, not the shortest route. Among them, the road traffic status information can generally be obtained from the official website of the National Highway Bureau of the Ministry of Communications of China and/or the General Administration of Highways of the Ministry of Communications. These websites can provide information on the road traffic conditions required for the creation, including various roads (for example Information on traffic conditions (such as speed, congested sections, estimated travel time, etc.) on highways, provincial roads, and county roads, and road sections that are restricted from being restricted.

In step d), the existing satellite navigation technology can be used to guide the user to the evacuation site, for example using augmented reality (AR) path navigation technology.

By the implementation of the above steps, the user can be quickly guided from the current location to the evacuation site for evacuation at the current location when the accident occurs. The servo device 2 can perform the above steps a to c according to the service program, thereby constructing the optimal evacuation route. The electronic device 3 can perform the above step d according to the application, so as to guide the user to the evacuation site, for example, the display of the electronic device 3 displays the optimal evacuation route in 2D or 3D or other manners. , the voice prompt of the turn, adjust the best evacuation route according to the current travel speed and position of the user. . . and many more. Wherein, the radiation accident information, the weather information and the road traffic condition information may be manually input into the servo device 2. Preferably, the service program is configured to enable the server 2 to immediately extract new radiation accident information and weather information from the websites 4 to 6 (for example, the official website mentioned above) to which the network 1 is linked. And information on road traffic conditions, such as radiation accident information. The evacuation site information may be pre-built in the service program, but may also be obtained by the server device 2 via the network 1 from a linked website, such as the official website of the Atomic Energy Commission of the Executive Yuan of China. In addition, as described above, in the case where the scope of the accident is known, the a step is not necessary for the service program.

In another preferred embodiment, the service program is configured to enable the servo device 2 to perform the steps a to b above to select an appropriate evacuation site, and the application is configured to enable the electronic device 3 The above steps c and d are carried out to construct the optimal evacuation route and guide the user to the evacuation site according to the optimal evacuation route. Wherein, as described above, in the case where the scope of the accident is known, for the service program, the step a Non-essential.
