Ships may face various possible dangers and accidents during navigation, such as fire, water leakage, grounding and collision, so it is very necessary to equip the ship with emergency items. These emergency items mainly include lifeboats, life jackets, lifebuoys, fire extinguishing equipment and first aid medicines. In an emergency, these emergency items can help crew members and passengers avoid life danger and protect the ship from further damage. In this context, there is a study on how to generate image data and display image data in an emergency so that crew members and passengers can quickly find emergency items.

[0003] In the prior art, emergency items are usually searched based on a pre-drawn emergency item location map, which requires staff to know the locations of various emergency items on the ship in advance and search based on the pre-drawn map.

It takes a long time to search based on the pre-drawn emergency item location map, and the search efficiency is low.

[0069] In conjunction with the accompanying drawings, the method, device, equipment and medium for displaying the positioning results of emergency items on board the ship provided by the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0070] Embodiment 1

[0071] Figure 1 1 is a flow chart of a method for displaying the positioning results of emergency items on board a ship provided in Example 1 of the present application. Figure 1 As shown, the specific steps include:

[0072] S101, transmitting a radio frequency signal of a preset frequency through a signal transmitter configured for emergency items.

[0073] First of all, the usage scenario of this solution can be to perceive the emergency situation of the ship through the perception sensor, transmit the perceived data to the smart terminal or chip for processing and analysis, and then the smart terminal or chip controls the signal transmitter to transmit the radio frequency signal to the base station when an emergency occurs. After the base station receives the emergency item coordinates and the cabin coordinates, it transmits this information to the smart terminal or chip to determine the emergency item positioning result through the smart terminal or chip, and transmit it to the display device for display.

[0074] Based on the above usage scenarios, it can be understood that the executor of the present application can be an emergency item locating system that integrates the perception of dangerous situations, transmits radio frequency signals, determines the emergency item locating results and displays the functions, and no excessive limitations are made here.

[0075] In this plan, emergency items can refer to items used to protect the personal safety of crew members and the safety of the ship in an emergency situation. They can include life-saving equipment such as lifeboats, life rafts, life jackets and lifebuoys; fire-fighting equipment such as fire extinguishers, fire hoses, gas fire-fighting systems and foam fire-fighting systems; medical rescue equipment such as medical kits, first aid kits and first aid equipment; communication and navigation equipment such as emergency communication equipment, signal lights, buoys and radar reflectors;

[0076] A signal transmitter can be a device for transmitting wireless signals, which is used to transmit the location information of emergency items to a receiving device through radio frequency signals. In the ship emergency item management system, each emergency item is equipped with a signal transmitter. When an emergency occurs on the ship, these signal transmitters will simultaneously transmit radio frequency signals so that the system can quickly locate the location of the emergency items. Among them, the receiving device can be a smart terminal or a chip.

[0077] The preset frequency radio frequency signal may refer to a pre-set signal frequency, which is used for modulation when the signal transmitter transmits the signal. Each emergency item signal transmitter is set with a preset radio frequency signal frequency so that the receiving device can identify and distinguish different signal sources. For example, it can be a wireless remote control signal with a frequency of 433MHz and 315MHz.

[0078] By installing sensing sensors, such as temperature sensors, smoke sensors, and water level sensors, at key parts of the ship, it is possible to determine whether an emergency has occurred by detecting environmental changes. Among them, the temperature sensor can sense changes in the ship's ambient temperature. If the temperature exceeds the safe range, dangerous situations such as fire may occur; the smoke sensor can sense the smoke concentration in the ship's environment. If the concentration exceeds the safe range, dangerous situations such as fire may occur; the water level sensor can sense changes in the water level in the ship's cabin. If the water level exceeds the safe range, dangerous situations such as water leakage may occur; the pressure sensor can sense changes in the pressure of the ship's oil tank or gas tank. If the pressure exceeds the safe range, dangerous situations such as leakage may occur. After the sensing sensor senses the emergency situation of the ship, it can transmit the sensed data to the intelligent terminal or chip for processing and analysis. The transmission method can be achieved through wired or wireless communication, such as through network connection, Bluetooth, and Wi-Fi. The intelligent terminal or chip can analyze the data collected by the sensor through pre-set programs and algorithms, and automatically determine whether it is necessary to transmit the radio frequency signal of the signal transmitter configured for emergency items. When the intelligent terminal or chip detects an emergency situation on the ship, it can send instructions to the signal transmitter through wireless communication to control it to transmit a radio frequency signal of a preset frequency. After receiving the command, the signal transmitter will emit a radio frequency signal.

[0079] S102: Receive the radio frequency signal through a base station, and determine the coordinate information of the emergency item in the base station coordinate system according to the radio frequency signal.

[0080] The base station can be a shipborne mobile base station, which consists of a radio transmitter and a receiver and can receive and send radio signals. The signal transmitter configured for the emergency items installed on the ship will send radio frequency signals, and the mobile base station will receive these signals and determine the location of the emergency items based on the strength and direction of the signal, thereby determining the coordinate information of the emergency items in the base station coordinate system. The mobile base station can determine its own position through the global positioning system and communicate with other sensors and devices to achieve the positioning and management of emergency items on the ship.

[0081] If the base station is a ship-borne mobile base station, the base station coordinate system can be a ship coordinate system with the mobile base station as the origin or a geographic coordinate system with a certain geographical location as the origin. If the ship coordinate system is used, the coordinate information of the emergency items in the base station coordinate system can be three-dimensional coordinates relative to the mobile base station. If the geographic coordinate system is used, the coordinate information of the emergency items in the base station coordinate system can be information such as longitude, latitude, and altitude. For example, if the ship coordinate system is used, the base station coordinate system can be a coordinate system with the ship as the origin, which can be expressed in a three-dimensional coordinate system, in which the center point of the hull is the origin, and the X-axis is positive to the right, the Y-axis is positive forward, and the Z-axis is positive upward, and the unit length is 1m. The coordinate information of the emergency items in the base station coordinate system can be a three-dimensional coordinate relative to the ship. For example, the coordinates of the emergency items can be (15, 5, 2), indicating that its position relative to the ship is 15m in the positive direction of the X-axis, 5m in the positive direction of the Y-axis, and 2m in the positive direction of the Z-axis. If the geographic coordinate system is used, the base station coordinate system can be a coordinate system with a certain geographical location as the origin, for example, the longitude and latitude of the ship as the origin. The coordinate information of the emergency item in the base station coordinate system can be expressed in a spherical coordinate system. For example, the coordinates of the emergency item can be (120°E, 30°N, 2m), indicating that its position on the earth is 120 degrees east longitude, 30 degrees north latitude, and 2 meters high, where the height is the sea level height.

[0082] If a ship-borne mobile base station is used, the radio frequency signal can be received and the coordinate information of the emergency items in the base station coordinate system can be determined in the following ways:

[0083] 1. Install receivers and antennas at key locations on the ship. The receivers and antennas can be used to receive radio frequency signals of preset frequencies emitted by signal transmitters configured for emergency items.

[0084] 2. Configure the base station equipment and connect it to the receiver and antenna. The base station equipment can be used to receive and process the received radio frequency signals and calculate the coordinate information of the emergency items in the base station coordinate system.

[0085] 3. Equip the emergency items with a radio frequency transmitter and set a preset frequency. When an emergency occurs, the radio frequency transmitter of the emergency item will transmit a radio frequency signal of the preset frequency.

[0086] 4. The base station device receives the RF signal of the preset frequency transmitted by the RF transmitter of the emergency item. Through methods such as signal strength indication and time difference measurement, the base station device can calculate the distance between the emergency item and the base station device, and determine the coordinate information of the emergency item in the base station coordinate system.

[0087] S103, fitting the pre-built cabin model to the base station coordinate system to obtain the cabin coordinates of the cabin model in the base station coordinate system.

[0088] The cabin model may refer to a three-dimensional model created on a computer that describes the cabin space shape, size, layout and other features, and may include information such as various cabin equipment, pipes and cables.

[0089] The cabin coordinates may refer to the position coordinates of the cabin model in the base station coordinate system. For example, if the ship coordinate system is used, if the cabin coordinates are (10, 3, 1), it means that its position relative to the ship is 10m in the positive direction of the X axis, 3m in the positive direction of the Y axis, and 1m in the positive direction of the Z axis. If the geographic coordinate system is used, if the cabin coordinates are (121°E, 31°N, 3m), it means that its position on the earth is 121 degrees east longitude, 31 degrees north latitude, and 3 meters high, where the height is the sea level height.

[0090] If the base station is a shipborne mobile base station, the current position coordinates can be obtained using GPS (Global Positioning System) and used as the origin in the base station coordinate system. Then, the base station can use a rangefinder and other equipment to measure the distance and direction between each point of the cabin model and the origin, thereby obtaining the coordinates of the cabin model in the base station coordinate system; it can also use an inertial navigation system to measure its own motion state, such as acceleration, angular velocity, and azimuth, to derive the current position and direction information. Then, the inertial navigation system is used to measure the distance and direction between each point of the cabin model and the base station, thereby obtaining the coordinates of the cabin model in the base station coordinate system.

[0091] S104, determining the target cabin where the emergency items are located according to the coordinate information of the emergency items and the coordinates of the cabin.

[0092] The target cabin may refer to a cabin that matches the location of the emergency items, that is, the cabin where the emergency items are located. For example, the base station is a shipborne mobile base station, the base station coordinate system is the ship coordinate system, and the cabin coordinate system is a three-dimensional coordinate system with the ship as the origin. In the cabin coordinate system, the cabin can be divided into several small areas. If the cabin of a cargo ship can be divided into multiple cargo holds, each cargo hold can be numbered from left to right and from bottom to top. If there are 5 cargo holds, numbered 001~005, the coordinates of each cargo hold can be represented by the coordinates in the cabin coordinate system. If the coordinate information of the emergency item is (5, 8, 4), the number of the target cabin where the emergency item is located can be determined by comparing it with the pre-built cabin model.

[0093] The shipborne mobile base station can transmit the coordinate information of the emergency items in the base station coordinate system and the cabin coordinates of the cabin model in the base station coordinate system to the smart terminal or chip through wireless networks such as WiFi and Bluetooth. Then the smart terminal can use the received coordinate information of the emergency items in the base station coordinate system to compare it with the cabin coordinates of the cabin model in the base station coordinate system to determine the target cabin where the emergency items are located. Specifically, the smart terminal can use an algorithm to calculate and match the coordinate information of the emergency items in the base station coordinate system and the cabin coordinates of the cabin model in the base station coordinate system to determine the target cabin where the emergency items are located. Among them, the matching algorithm can take into account information such as the distance, direction, speed and acceleration between the items and the cabin; the smart terminal can also use existing maps and positioning technologies to compare the coordinate information of the emergency items with the cabin model to determine the target cabin.

[0094] S105, displaying the location result of the emergency items through a display device.

[0095] Display devices can be various types of display screens, such as mobile devices (such as mobile phones, tablets, and handheld displays) or fixed devices (such as televisions and computer monitors).

[0096] The positioning result of the emergency items can be to determine the target cabin where the emergency items are located through the base station and the cabin model, and display it on the display device in the form of a graphic or map, etc. For example, the location of the target cabin is marked on a map, or the number or name of the target cabin is displayed.

[0097] Smart terminals can display the location results of emergency items on the device by connecting to the display device. For example, for portable devices such as mobile phones, the location results can be displayed by displaying a map on the screen and marking the location of the emergency items. For fixed display devices such as televisions and display screens, the location results can be displayed by marking the location of the emergency items on a map or floor plan.

[0098] In an embodiment of the present application, a radio frequency signal of a preset frequency is transmitted through a signal transmitter configured for emergency items; the radio frequency signal is received through a base station, and the coordinate information of the emergency items in the base station coordinate system is determined according to the radio frequency signal; the pre-constructed cabin model is fitted to the base station coordinate system to obtain the cabin coordinates of the cabin model in the base station coordinate system; the target cabin where the emergency items are located is determined according to the coordinate information of the emergency items and the cabin coordinates; the positioning result of the emergency items is displayed through a display device. Through the above-mentioned method for displaying the positioning results of emergency items in the ship, the emergency items can be located in real time according to the transmission and reception of radio frequency signals. At the same time, the use of a pre-constructed cabin model can simplify the process of determining the cabin coordinates and improve the accuracy and speed of positioning. Finally, the location of the emergency items can be intuitively displayed through the display device, which is convenient for the staff to handle quickly and accurately, and improves the efficiency and accuracy of emergency response.

[0099] Embodiment 2

[0100] Figure 2 2 is a flow chart of a method for displaying the location results of emergency items on board a ship provided in Example 2 of the present application. Figure 2 As shown, the specific steps include:

[0101] S201, transmitting a radio frequency signal of a preset frequency through a signal transmitter configured for emergency items.

[0102] S202: Receive the radio frequency signal through a base station, and determine the coordinate information of the emergency item in the base station coordinate system according to the radio frequency signal.

[0103] S203, fitting the pre-built cabin model to the base station coordinate system to obtain the cabin coordinates of the cabin model in the base station coordinate system.

[0104] S204, determining the target cabin where the emergency items are located according to the coordinate information of the emergency items and the coordinates of the cabin.

[0105] S205: Display the positioning result of the emergency items through a display device.

[0106] S206: Acquire location information of the display device.

[0107] The location information of the display device may be coordinate information relative to the smart terminal. For example, if the location coordinates of the smart terminal are (50, 100), the location coordinates of the display device relative to the smart terminal are (30, -20).

[0108] If the display device has a built-in GPS chip, the smart terminal can communicate with the display device to obtain its GPS positioning information and thus determine its location; if the display device has a built-in Bluetooth chip, the smart terminal can scan the Bluetooth signal and use the Bluetooth positioning technology to determine the location information of the display device; the smart terminal can also scan the surrounding WiFi signals and use the WiFi positioning technology to determine the location information of the display device.

[0109] Based on the above technical solutions, optionally, after obtaining the location information of the display device, the method further includes:

[0110] According to the display device coordinates, the coordinate information of the emergency items, and the cabin model, path information for personnel in the display area of ​​the display device to reach the emergency items is determined.

[0111] In this solution, the path information may refer to the route information from the location of the display device to the location of the emergency items, and may include information such as the walking route, walking distance, and walking time. For example, if the cabin model is a three-dimensional model, assuming that the location coordinates of the display device are (x1, y1, z1), the location coordinates of the emergency items are (x2, y2, z2), and the walking route of the personnel is a plurality of continuous points, and the coordinates of each point are (xi, yi, zi), then the path information may include the following numbers:

[0112] 1. Number of points n on the walking route

[0113] 2. The coordinates of each point (xi, yi, zi), i = 1, 2, ..., n

[0114] 3. The distance between each point is di, i=1, 2, ..., n-1

[0115] 4. Total walking distance D = ∑di, i = 1, 2, ..., n-1

[0116] 5. Walking time t can be estimated based on the walking speed and walking distance of the person.

[0117] The intelligent terminal can determine the path information through the path planning algorithm according to the following steps:

[0118] 1. Determine the starting point and the end point. The starting point is the location of the display equipment, and the end point is the location of the emergency items.

[0119] 2. Convert the cabin model into a graph, with each position in the cabin as a node and the walkable paths in the cabin as edges.

[0120] 3. Use a path search algorithm in the graph, such as Dijkstra's algorithm, to find the shortest path from the starting point to the end point.

[0121] 4. Based on the search results, calculate the path length and walking time from the display device to the emergency items.

[0122] In this solution, by determining the path information from the display device to the emergency supplies, the efficiency and accuracy of the emergency response can be improved. By providing the path information, emergency response personnel can be helped to quickly and accurately reach the emergency supplies, thereby better responding to the emergency.

[0123] Based on the above technical solutions, optionally, after determining the path information of the personnel in the display area of ​​the display device to reach the emergency items, the method further includes:

[0124] Determine the remaining quantity of the emergency items according to the quantity of the emergency items at the emergency item location and the number of personnel moving toward the emergency item location determined according to the path information;

[0125] When displaying the path information to the emergency items, the remaining quantity of the emergency items is updated synchronously.

[0126] In this solution, the number of emergency items may be the total number of emergency items in the cabin, for example, may include the number of fire extinguishers, the number of life buoys, the number of oxygen cylinders, etc.

[0127] The number of people moving toward the emergency items may be the number of people moving toward the emergency items.

[0128] The remaining number of emergency items can be the number of emergency items remaining after a period of time in the emergency scene, which can be calculated based on the number of emergency items and the number of people moving to the emergency items. If each person takes out an emergency item each time, if there are N people and the number of emergency items is M, then the remaining number L of emergency items can be:

[0129] ;

[0130] The smart terminal can determine the number of people moving to the emergency items based on the path information of people in the display area of ​​the display device to the emergency items. Specifically, the smart terminal can calculate the speed of people moving and the arrival time based on parameters such as distance and time in the path information, thereby estimating the number of people arriving at the emergency items. For example, if the display device is a TV or a computer, the smart terminal can determine the number of people around the display device by receiving the base station signal, thereby calculating the number of people moving to the emergency items. Then, based on the path information and the distance between the location of the display device and the location of the emergency items, the time to arrive at the emergency items is calculated, thereby determining the number of people arriving at the emergency items.

[0131] After the path information to the emergency supplies is determined, the intelligent terminal can calculate the remaining number of emergency supplies based on the known number of emergency supplies and the number of people moving to the emergency supplies. That is:

[0132] ;

[0133] Then, the remaining quantity information is sent to the display device together with the path information, and the display device displays the remaining quantity information while displaying the path information, so as to achieve synchronous update. Specifically, the remaining quantity information can be displayed in the form of text, pictures or sounds.

[0134] In this solution, the number of emergency items and the movement of personnel can be monitored in real time through smart terminals, so that on-site conditions can be monitored in real time, so that timely measures can be taken to make adjustments and effectively improve emergency response capabilities. At the same time, monitoring the movement of personnel can improve management efficiency and reduce the waste of manpower and material resources.

[0135] On the basis of the above technical solutions, optionally, the display device includes a movable display device or a fixed display device;

[0136] The process of determining the number of personnel moving toward the emergency items according to the path information includes:

[0137] Obtain the display device coordinate update result of the movable display device;

[0138] According to the fitting result of the display device coordinate update result and the path information, it is determined whether the person holding the current movable display device is the person moving toward the emergency item, so as to obtain the number of people moving toward the emergency item.

[0139] In this solution, the movable display device may be a display device that is movable and easy to carry, such as a mobile phone, a watch, and a tablet computer.

[0140] Fixed display equipment may be display equipment that cannot be moved and is generally fixed in a specific location, such as a television and a desktop computer.

[0141] The display device coordinate update result may refer to the current coordinate information update of the display device obtained by fitting the display device location information to the base station coordinate system. When the display device location coordinate changes, the latest location information will be updated to the smart terminal.

[0142] The smart terminal can obtain the real-time location coordinates of the mobile display device through the sensor or GPS module connected to the mobile display device, and send the location information to the smart terminal through network transmission to update the display device coordinates in real time. The mobile display device can also obtain location information through built-in positioning functions, such as Wi-Fi positioning and Bluetooth positioning, and send it to the smart terminal for location update.

[0143] The fitting result may be a matching result obtained by comparing and matching the coordinate information of the display device with the path information. The matching result may reflect whether the person holding the display device is moving toward the emergency item, and may determine the direction and speed of movement.

[0144] The intelligent terminal can fit the coordinate information of the display device with the path information to obtain the position information of the display device on the path. Then, the intelligent terminal can determine whether the current display device is on the path of the person moving to the emergency items based on the obtained position information and path information. If so, the holder of the display device can be counted in the number of people moving to the emergency items. Specifically, it can be determined whether the display device is on the path by calculating the angle between the position of the display device on the path and the direction of travel of the person moving to the emergency items. If the angle is less than a certain threshold, it can be considered that the display device is on the path. At the same time, the intelligent terminal also needs to consider the distance between the display device and the moving person. Only when the distance is within a certain range can the holder of the display device be considered as one of the people moving to the emergency items. Finally, based on these judgment results, the intelligent terminal can obtain the number of people moving to the emergency items.

[0145] In this solution, the current location of the display device can be obtained through the display device coordinate update result of the display device, and then the fitting result with the path information can be used to determine whether the person holding the display device is moving towards the emergency items, thereby obtaining the number of moving people. In this way, the situation of people around the emergency items can be more accurately understood, so as to better organize emergency rescue and resource allocation.

[0146] On the basis of the above technical solutions, optionally, the display device includes a movable display device or a fixed display device;

[0147] After determining the path information of the personnel in the display area of ​​the display device to reach the emergency items, the method further includes:

[0148] Obtain the display device coordinate update result of the movable display device;

[0149] The path information is dynamically updated according to the update result of the display device coordinates and the cabin model.

[0150] In this solution, the intelligent terminal can locate the display device in the cabin model according to the coordinates of the display device and determine the current location of the display device. Then, the shortest path from the current location of the display device to the emergency items is calculated through the path information in the cabin model, and the path is updated to the display device. The updated path information is displayed in real time on the display device to guide people to move to the emergency items.

[0151] In this solution, by updating the coordinate information of the display device in real time, the intelligent terminal can accurately grasp the location information of the personnel, so as to adjust the path information in time to ensure that the personnel can quickly reach the emergency items. In addition, by dynamically updating the path information, the path planning is made more intelligent and real-time, which can more effectively guide the actions of personnel and improve the efficiency of emergency response.

[0152] Based on the above technical solutions, optionally, after determining the remaining quantity of the emergency items, the method further includes:

[0153] If the remaining quantity reaches a preset threshold, identifying whether the remaining quantity at another emergency item satisfies a path switching condition;

[0154] If the path switching condition is met, the display switches from displaying the path information to the current emergency item to displaying the path information to another emergency item.

[0155] In this solution, the preset threshold may be the minimum inventory level of emergency items. When the remaining quantity of emergency items is lower than this value, an early warning may be automatically triggered or the staff may be automatically notified to replenish the items.

[0156] The path switching condition may be that the remaining quantity at another emergency item must be greater than a preset threshold, and the smart terminal has determined that the current holder of the movable display device is a person moving toward the emergency item. The smart terminal will switch the path only if both conditions are met.

[0157] When the remaining quantity reaches a preset threshold, the smart terminal can start to detect whether the remaining quantity at another emergency item meets the path switching condition. Specifically, the smart terminal can obtain the remaining quantity information at the emergency item from the sensor set at the emergency item through wireless communication. After obtaining the remaining quantity information, the smart terminal will make a judgment based on the preset path switching condition to decide whether to switch the path.

[0158] The intelligent terminal can switch the path information through the following steps:

[0159] 1. Obtain information showing the path to another emergency item.

[0160] 2. Dynamically update the path information based on the updated results of the display device coordinates and the cabin model and other information.

[0161] 3. Switch the displayed path information so that the displayed content shows the path information to another emergency item, and at the same time, update the map of the display area.

[0162] 4. Continue to monitor the current number of emergency items and perform path switching operations when necessary.

[0163] In this solution, by dynamically updating the path information of the display device to the emergency items, it is possible to respond to emergency situations more flexibly and improve the efficiency of emergency response. When the remaining quantity of a certain emergency item reaches the preset threshold, the remaining quantity of another emergency item and whether the arrival path meets the path switching conditions can be judged to achieve dynamic path switching, ensuring that the staff can reach the emergency items with a large remaining quantity in time, minimizing the losses caused by emergency accidents.

[0164] S207, fitting the position information to the base station coordinate system to obtain the display device coordinates.

[0165] The display device coordinates may refer to the position of the display device relative to the origin of the base station, and may be represented by a three-dimensional coordinate vector, including the coordinate values ​​of the display device in the x, y, and z directions. For example, the coordinate value of the display device in the base station coordinate system may be represented as (20, 15, 5). If the unit length is 1m, it means that the distance of the display device from the origin of the base station coordinate system to the X axis is 20m, the distance from the Y axis is 15m, and the distance from the Z axis is 5m.

[0166] The smart terminal can first obtain the location information of the base station and calibrate it to ensure that the coordinate system in the base station coordinate system is accurate. For example, the location information of the base station can be obtained through positioning systems such as GPS. Then, the smart terminal can convert the location information of the display device from its coordinate system relative to the smart terminal to the coordinate system relative to the base station through a certain algorithm. Among them, the algorithm may include a coordinate transformation method and a distance measurement method. The coordinate transformation method may be to transform the coordinate information of the display device relative to the smart terminal and convert it to the base station coordinate system. This transformation can be calculated by the pre-measured base station position and direction vector; the distance measurement method may be to measure the distance between the smart terminal and the display device, combined with the base station position and direction vector, to calculate the coordinates of the display device in the base station coordinate system.

[0167] S208: Determine distance information from the display area of ​​the display device to the emergency item according to the display device coordinates and the coordinate information of the emergency item.

[0168] The display area of ​​a display device may be the range within which the device can display information or play videos and other content to users. The size and shape of the display area depends on the type and performance of the display device, such as screen size and resolution.

[0169] The distance information from the display area of ​​the display device to the emergency item may refer to the straight-line distance between the display device and the emergency item. This distance information may be used to help the smart terminal calculate the relative position relationship between the emergency item and the display device, thereby determining the content and method of displaying the emergency item.

[0170] The smart terminal can determine the distance information between the display area of ​​the display device and the emergency item by calculating the distance between the coordinates of the display device and the coordinates of the emergency item. Specifically, the Euclidean distance formula can be used to calculate the distance between two points. For example, if the coordinates of the display device are (x1, y1, z1) and the coordinates of the emergency item are (x2, y2, z2), the Euclidean distance between them can be expressed as:

[0171] ;

[0172] In this embodiment, obtaining the distance information between the display device and the emergency items can realize the accurate positioning of the display device and the emergency items, improve the positioning accuracy, and thus improve the efficiency and accuracy of emergency response. For mobile devices, the real-time update of the display device location information can improve the positioning accuracy of the mobile device, making it more convenient for staff to manage and control the mobile device.
