Description

Technical Field

[0001] This application relates to the field of landslide life detection technology, and in particular to an auxiliary positioning device and method for search and rescue under landslides. Background Technology

[0002] A landslide is a geological hazard caused by the displacement of rock and soil on a slope along a deeply penetrated, weak interface. It is mainly caused by factors such as rainfall, earthquakes, snowmelt, and human activities, which loosen and slide surface materials. Landslides not only cause great harm to human production and lives but can also lead to serious casualties and property damage. To promptly locate and rescue those buried under landslide debris and reduce casualties, rescue workers use various detection technologies to pinpoint the location of people under the rubble.

[0003] Among related technologies, the following techniques are mainly used for locating people under landslides: Infrared detection devices are only suitable for open outdoor environments due to their weak penetration; acoustic-optical-electric detection devices can detect heartbeats or knocking sounds from trapped individuals, detecting sound waves, but require a relatively quiet rescue environment, which is often difficult to achieve in practice; optical detection devices require probes through gaps to reach the trapped individuals, but not all landslides have gaps allowing direct access; life detection devices can locate people buried under landslides using vital signs, but their effective range is often limited due to harsh working conditions.

[0004] However, landslide positioning technology is only applicable to open outdoor scenes or quiet environments, or has relatively harsh usage conditions. The limited range of applications makes it difficult to accurately and effectively locate trapped personnel in complex environments, and it cannot meet the needs of actual rescue operations. This issue urgently needs to be addressed. Summary of the Invention

[0005] This application provides an auxiliary positioning device and method for search and rescue under landslides, in order to solve the problems that the landslide positioning technology in the related technology is only applicable to open outdoor scenes or quiet environments, or the conditions of use are more demanding. The relatively simple use environment leads to a narrow scope of application of the landslide positioning technology, making it difficult to accurately and effectively locate the position of trapped people in complex environments, and failing to meet the needs of landslide positioning technology in actual rescue.

[0012] Optionally, in one embodiment of this application, the method further includes: receiving the acoustic wave and / or the laser from the auxiliary positioning device; and generating guidance information for the actual position based on the acoustic wave and / or the laser.

[0016] This application embodiment can create an abnormal area for landslide detection using absorbing materials, sound wave emitting devices, and light wave emitting devices, providing a positioning target for ground detection devices. This gives ground detection and rescue a clear positioning direction, significantly improving positioning accuracy and efficiency. Therefore, it solves the problems of related technologies where landslide positioning technology is only applicable to open outdoor scenes or quiet environments, or where the usage conditions are relatively harsh. The limited application environment leads to a narrow scope of application for landslide positioning technology, making it difficult to accurately and effectively locate trapped personnel in complex environments, and failing to meet the actual needs of landslide positioning technology in rescue operations.

Detailed Implementation

[0026] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] The following description, with reference to the accompanying drawings, describes an auxiliary positioning device and method for landslide search and rescue according to embodiments of this application. Addressing the problem that landslide positioning technologies mentioned in the background art are only applicable to open outdoor scenes or quiet environments, or have relatively harsh operating conditions, resulting in a narrow scope of application and difficulty in accurately and effectively locating trapped personnel in complex environments, thus failing to meet the needs of actual rescue operations, this application provides an auxiliary positioning device for landslide search and rescue. In this device, an abnormal area for landslide detection can be formed using absorbing materials, sound wave emitting devices, and light wave emitting devices, providing a positioning target for ground detection devices. This gives ground detection and rescue a clear positioning direction, significantly improving positioning accuracy and rescue efficiency. Therefore, this solves the problems of related technologies where landslide positioning is only applicable to open outdoor scenes or quiet environments, or has relatively harsh operating conditions, resulting in a narrow scope of application and difficulty in accurately and effectively locating trapped personnel in complex environments, thus failing to meet the needs of actual rescue operations.

[0028] The following describes the structural schematic diagram and the principle schematic diagram of the actual working arrangement of the auxiliary positioning device for search and rescue under landslides involved in the embodiments of this application.

[0029] Figure 1 This is a schematic diagram of an auxiliary positioning device for search and rescue under a landslide, according to one embodiment of this application. Figure 1 As shown, the auxiliary positioning device used for search and rescue under landslide bodies includes: 1-outer layer material; 2-middle layer material; 3-inner layer material; 4-sound wave emitting device; 5-real-time positioning device; 6-light wave emitting device; 7-auxiliary donning and doffing device.

[0030] Specifically, Figure 2 This is a schematic diagram of an auxiliary positioning device for search and rescue under a landslide, provided as an embodiment of this application.

[0031] like Figure 2 As shown, the auxiliary positioning device 10 for search and rescue under landslides includes: a wearable body 100 and a positioning component 200, wherein the positioning component 200 includes: a timing positioning device and a guiding device.

[0032] Wearable device 100, worn by trapped personnel participating in search and rescue operations under the landslide before the landslide disaster occurs.

[0033] In some embodiments, landslide hazards here include, but are not limited to, landslides caused by natural environmental factors, human factors, and material composition and structure. A landslide is a displacement geological hazard that occurs when rock and soil masses on a slope move along a deeply penetrated, weak, and fractured interface.

[0034] For example, heavy rain, torrential rain, and prolonged continuous rainfall can cause surface water to seep into the slope, softening the rock, soil, and weak surfaces, making it highly susceptible to landslides. Earthquakes can also cause slope swaying, disrupting the slope's balance and easily triggering landslides. Surface water bodies such as rivers can continuously scour or soak the toe of the slope, weakening its support or softening the rock and soil, reducing its strength, and potentially triggering landslides as well.

[0035] Slopes with loose soil layers, gravelly soil, weathered crust, and semi-lithified soil layers have low shear strength and are prone to deformation and sliding. In hard rock, if a sliding surface exists, especially after heavy rain, the shear strength of the sliding surface is greatly reduced due to water soaking, making it easy to slide.

[0036] For example, after a landslide, rescuers need to rescue people trapped under the landslide. However, landslides are often highly unpredictable and may occur repeatedly, meaning rescuers may encounter further landslides and easily be buried. To facilitate the rescue of trapped personnel involved in landslide rescue operations and ensure the safety of rescuers, this application embodiment can employ a wearable device 100, which can be worn by trapped personnel who may be affected by a landslide before it occurs.

[0037] After a landslide, rescue workers may not be able to prepare or equip themselves with a large amount of sophisticated rescue equipment immediately. However, in order to rescue trapped people as quickly as possible, rescuers need to set off quickly, which is where the wearable device 100 comes in handy. As a wearable device, the wearable device 100 is relatively simple and convenient, easy to prepare in large quantities, and can be worn directly by rescuers when preparing to participate in the rescue, without adding extra burden to the rescuers.

[0038] For example, personnel working in areas at risk of landslides can wear the wearable device 100 at any time during their daily work. If a landslide occurs and the personnel are buried under the landslide mass, the wearable device 100 will be buried along with the personnel, making it easier to rescue the personnel based on the wearable device 100.

[0039] In this embodiment, the wearable device 100 can be worn in advance by trapped personnel participating in the search and rescue work under the landslide before the landslide disaster occurs. It is simple and convenient, and can also be used to assist in subsequent search and rescue operations under the landslide.

[0040] Optionally, in one embodiment of this application, the wearable body 100 includes at least one of clothing, pants, and a hat.

[0041] Based on the descriptions of other embodiments, it is understood that, in order to facilitate the rapid use of readily available auxiliary positioning devices for search and rescue under landslides before a landslide disaster occurs, the embodiments of this application may configure them as wearable auxiliary devices.

[0042] Specifically, wearable assistive devices can be, but are not limited to, portable devices in the shape of clothing, such as clothes, pants, and hats, that can be worn.

[0043] For example, in cases of landslides caused by heavy rain, rescuers may need to wear one-piece waterproof suits. In such cases, rescuers can choose the wearable body 100, which is easy to use when needed.

[0044] For example, in some disasters caused by geological conditions, clothing with special functions is needed. In this case, wearable body 100 in the form of pants or hats can be used.

[0045] Optionally, in one embodiment of this application, the wearable body 100 includes an outer layer material, a middle layer material, and an inner layer material, wherein the outer layer material is woven from ultra-high strength fibers; the middle layer material is woven from wave-absorbing crystal fibers; and the inner layer material is woven from ultra-fine denier fibers and high-count combed cotton.

[0046] Understandably, landslides can recur in areas where landslides have occurred, and various objects may fall with them. Furthermore, during search and rescue operations, the rescue sites may contain various obstacles and dangerous objects; therefore, the performance and materials of the wearable body 100 need to be taken into consideration.

[0047] In some embodiments, the wearable body 100 may be configured to consist of three layers of material: an outer layer, a middle layer, and an inner layer.

[0048] The outer layer material may be, but is not limited to, woven from ultra-high strength fibers. The extremely high tensile strength and abrasion resistance of ultra-high strength fibers can prevent cuts and punctures, help cope with the challenges of complex environments and climatic conditions, and effectively protect the human torso from damage caused by debris, branches and other materials carried by landslides, thereby ensuring the safety of personnel.

[0049] The middle layer material can be, but is not limited to, woven from microwave-absorbing crystal fibers, a special type of fiber specifically designed to absorb electromagnetic waves. These fibers have a unique crystal structure that efficiently converts electromagnetic wave energy into other forms of energy (such as heat), thereby reducing electromagnetic wave reflection and transmission. For example, in search and rescue operations, rescuers typically use electromagnetic waves to locate trapped individuals. However, the complex and variable ground environment causes electromagnetic waves to be affected by various factors during propagation, such as terrain, soil moisture, and buildings, leading to signal attenuation and interference. When electromagnetic waves pass through the middle layer of wearable equipment, the microwave-absorbing crystal fibers quickly absorb and weaken their energy, which can be used to alert rescuers to the presence of trapped individuals nearby.

[0050] The inner layer material can be, but is not limited to, woven from microfiber and high-count combed cotton to form a breathable lining. This increases the durability of the garment while enhancing its wicking properties, keeping trapped individuals dry and comfortable. Simultaneously, the breathable lining also provides some warmth by maintaining airflow within the garment, preventing excessive heat loss and helping to keep the body warm. Furthermore, the breathable lining can also serve as a protective layer for the waterproof and breathable coating, preventing sweat and oil from clogging the pores in the coating and ensuring the garment's breathability and waterproof performance.

[0051] Optionally, in one embodiment of this application, the auxiliary positioning device for search and rescue under a landslide body further includes: a donning and doffing auxiliary device for fixing the wearable body 100 to the user's body.

[0052] In actual operation, the donning and doffing of the wearable device 100, as well as its securing to the trapped person, play a crucial role during rescue and while awaiting rescue. Therefore, this embodiment of the application can include a donning and doffing assistance device to help the user secure the wearable device 100.

[0053] For example, the dressing and doffing aid can consist of Velcro on both sides, which are fixed to the sides of the garment to help the wearable body 100 be securely worn on the human body.

[0054] For example, when putting on the wearable device 100 quickly or when it is inconvenient, you only need to put on the clothes and press the Velcro together directly, without having to manually or complicatedly handle it multiple times with both hands, such as with multiple buttons; when taking off the wearable device 100 quickly or when it is inconvenient, you only need to use a suitable tool to pry the letter stickers apart from the middle, without having to use your hands or perform overly complicated operations.

[0055] Furthermore, after securing the adhesive strip, it also helps to fix the wearable body 100 on the human body, so as to ensure that the wearable body 100 does not easily fall off the human body.

[0056] The positioning component 200 is disposed on the wearable body 100, wherein the positioning component 200 includes a real-time positioning device and a guidance device.

[0057] As one possible implementation, this application embodiment can also provide a positioning component 200 on the wearable body 100 to assist in the subsequent detection and positioning of trapped personnel participating in rescue work. The positioning component 100 includes a real-time positioning device and a guidance device.

[0058] The real-time positioning device and guidance device in the embodiments of this application will be further described below.

[0059] A real-time positioning device is used to obtain the current location of the auxiliary positioning device, enabling search and rescue personnel to locate the actual location of the trapped person.

[0060] As can be understood, real-time positioning here refers to a technology that uses positioning technology to identify the location, direction of movement, and dynamic changes of an object. Users acquire the real-time location of an object using various telemetry tools, such as the Global Positioning System (GPS) and Wireless Positioning System (WPS), and track the object's dynamic changes on a predetermined target. A real-time positioning device here can be understood as a device mounted on a wearable body 100 that uses real-time positioning technology to locate the position information of a target object and can promptly feedback this information.

[0061] For example, real-time positioning technologies mainly include the following: The BeiDou Navigation Satellite System (BDS) achieves centimeter-level or even millimeter-level positioning accuracy through multi-frequency, multi-system fusion positioning technology. BDS has achieved global coverage, meaning users can receive BeiDou satellite signals regardless of their location, providing seamless global positioning services. Furthermore, BDS employs advanced signal processing technology, enabling it to maintain stable signal reception in complex environments. Even under adverse conditions such as signal blockage and multipath interference, BDS maintains high positioning accuracy and stability.

[0062] In addition, there is the Global Positioning System (GPS): GPS is a navigation system developed and operated by the US government that uses a series of satellites in Earth orbit to determine information such as the position, speed, and time of receiving devices; base station positioning technology: relies on the signal processor connected to the mobile phone / terminal to determine the location of people or equipment, and can accurately determine a specific location, but only within a certain range; in addition, there are Beidou positioning technology, RFID (Radio Frequency Identification) positioning technology, WiFi positioning technology, etc.

[0063] Furthermore, embodiments of this application can use a real-time positioning device to obtain the current location of the auxiliary positioning device, enabling search and rescue personnel to locate the actual location of the trapped person.

[0064] For example, small GPS locators use GPS (Global Positioning System) satellites for positioning, offering high accuracy and are often used in scenarios such as preventing people from getting lost. They are easy to carry and conceal. Miniature GPS tracking devices, such as AirTag and iTag, feature a miniature design and are suitable for tracking objects. They are small, lightweight, easy to conceal, and have global positioning capabilities. Other small real-time positioning devices, such as smartwatches and smart bracelets, are also typically equipped with real-time positioning capabilities and offer additional functions such as health monitoring and communication.

[0065] Furthermore, in this embodiment of the application, these real-time positioning devices can be installed on the wearable body 100. When rescuing trapped personnel, the current location of the auxiliary positioning device can be obtained through the real-time positioning device, that is, the location of the trapped personnel can be obtained, and the location information can be transmitted to the rescue center, providing strong data support for rescue decision-making.

[0066] Guiding device, used to guide and locate search and rescue personnel.

[0067] Based on the descriptions of other embodiments, it is understood that real-time positioning devices can help rescuers locate the position of trapped persons, and once the location is determined, search and rescue operations can be conducted. To expedite the search and rescue of trapped persons, embodiments of this application may employ a guiding device to guide rescuers to the location of the trapped persons.

[0068] In some embodiments, the guidance device can serve as an auxiliary tool specifically designed for search and rescue personnel in landslide accidents, ensuring that in complex and ever-changing landslide site environments, it can quickly and accurately provide guidance and positioning for search and rescue personnel, bringing great convenience and efficiency improvement to search and rescue work.

[0069] For example, the guidance device can employ advanced wireless communication technology to ensure stable communication between rescue personnel and with the command center even in the event of communication disruptions or signal interference caused by landslides. The real-time positioning device on the wearable unit 100 can track the specific location of rescue personnel in real time, enabling timely rescue of trapped individuals.

[0070] In addition, the guidance device is waterproof, dustproof, and shockproof, enabling it to operate stably in harsh outdoor environments. Its compact design allows search and rescue personnel to easily carry it without worrying about it becoming a burden during rescue operations.

[0071] Furthermore, the guiding device in this embodiment can also be equipped with some small devices that are more convenient for rescuers to use, which will be further explained below.

[0072] Optionally, in one embodiment of this application, the guiding device includes: an acoustic wave emitting device for emitting acoustic waves for guiding and positioning; and / or an optical wave emitting device for emitting laser light for guiding and positioning.

[0073] In actual operation, the guidance device can also be equipped with sound wave emitting devices and light wave emitting devices, such as sound alarm systems and lights. Among them, the sound wave emitting device can emit sound waves to guide and locate trapped personnel, and the light wave emitting device can emit lasers to guide and locate trapped personnel.

[0074] For example, the sound wave emitting device may consist of, but is not limited to, a suspension rope and a whistle. The suspension rope can connect the whistle to the wearable body 100. During a rescue, the trapped person under the landslide can blow the whistle to activate the sound wave detection device. At the same time, when the person is near the rescuers, the whistle can also attract the rescuers' attention, helping the rescuers find the trapped person and reminding them to pay attention to the rescue environment to avoid accidents.

[0075] The light-emitting device can, but is not limited to, consist of a flashlight that emits a high-frequency laser and is suspended by a thin rope. The rope connects the flashlight to a wearable device 100. During rescue operations, trapped individuals under the landslide can use the flashlight to emit a high-frequency laser to activate the light-emitting detection device. Simultaneously, the flashlight can attract the attention of rescuers by shining its light on them. Additionally, in situations where landslide sites are dimly lit, visibility is low, or rescue operations are conducted at night, the light can emit a conspicuous beam of light, providing illumination and clear direction for search and rescue personnel.

[0076] This application embodiment can guide and locate rescue personnel to find people buried under landslides using sound wave emitting devices and light wave emitting devices, reducing blind searches by rescue personnel in complex and dangerous environments. Especially in unstable geological environments such as landslides, remote positioning can reduce blind searches by rescue personnel in complex and dangerous environments, and improve the safety and efficiency of search and rescue work.

[0077] The auxiliary positioning device for landslide search and rescue proposed in this application can form an abnormal area for detection under the landslide through absorbing materials, sound wave emitting devices, and light wave emitting devices, providing a positioning target for ground detection devices. This gives ground detection and rescue a clear positioning direction, significantly improving positioning accuracy and rescue efficiency. Therefore, it solves the problems of related technologies where landslide positioning technology is only applicable to open outdoor scenes or quiet environments, or where the usage conditions are relatively harsh. The limited application environment leads to a narrow scope of application for landslide positioning technology, making it difficult to accurately and effectively locate trapped personnel in complex environments, and failing to meet the actual needs of landslide positioning technology in rescue operations.

[0078] Next, referring to the accompanying drawings, an auxiliary positioning method for search and rescue under landslides, according to an embodiment of this application, is described.

[0079] Figure 3 This is a schematic diagram of the auxiliary positioning method for search and rescue under a landslide body according to an embodiment of this application.

[0080] like Figure 3 As shown, the auxiliary positioning method for search and rescue under a landslide includes the following steps:

[0081] Step S301: Based on the current location, transmit electromagnetic waves to the trapped personnel who participated in the search and rescue work under the landslide before the landslide disaster occurred, wherein the trapped personnel are wearing auxiliary positioning devices;

[0082] In some embodiments, once it is known that the trapped personnel are wearing auxiliary positioning devices, the real-time positioning device on the auxiliary positioning device can be used to transmit electromagnetic waves to the trapped personnel who participated in the search and rescue work under the landslide before the landslide occurred, based on their current location, using ground detection devices such as ground-penetrating radar, thereby more accurately locating the trapped personnel. For example, when searching for workers buried under a landslide, common electromagnetic wave transmitting devices can be used to transmit electromagnetic waves under the landslide to detect the location of the trapped personnel wearing auxiliary positioning devices.

[0083] Step S302: Receive electromagnetic wave data reflected by the auxiliary positioning device;

[0084] Based on the descriptions of other embodiments, it is understood that after electromagnetic wave data is transmitted down into the landslide body, the middle layer material in the wearable body 100 will absorb and weaken the electromagnetic wave data. Therefore, this embodiment can also receive electromagnetic wave data reflected back from the auxiliary positioning device, so as to determine whether there are trapped personnel wearing the auxiliary positioning device by whether there is any abnormality in the reflected electromagnetic wave data.

[0085] Step S303: Generate an electromagnetic wave intensity profile based on the electromagnetic wave data, and determine the actual position of the auxiliary positioning device based on the electromagnetic wave intensity profile.

[0086] As one possible approach, due to the absorption effect of the middle layer material of the auxiliary positioning device, the reflected electromagnetic waves will exhibit anomalies. Therefore, the embodiments of this application can process the reflected electromagnetic wave data to obtain an electromagnetic wave intensity profile. The electromagnetic waves, after absorption and weakening, will form a significant anomaly zone in the underground electromagnetic wave intensity profile. By analyzing the location and characteristics of this anomaly zone, rescue personnel can accurately locate the trapped individuals. Thus, the location of the auxiliary positioning device buried under the landslide can be determined based on the electromagnetic wave intensity profile, thereby completing the location of the buried individuals under the landslide.

[0087] Optionally, in one embodiment of this application, the auxiliary positioning method for search and rescue under a landslide body further includes: receiving sound waves and / or lasers from the auxiliary positioning device; and generating guidance information of the actual location based on the sound waves and / or lasers.

[0088] In other embodiments, when a trapped person equipped with an auxiliary positioning device emits certain sound waves, such as alarm sounds, and light waves, such as lasers, through a sound wave emitting device and a light wave emitting device, the search and rescue personnel can receive the sound and laser emitted by the auxiliary positioning device and generate certain guidance information based on the source and location of the sound and laser. The search and rescue personnel can then quickly locate the trapped person based on the guidance information.

[0089] It should be noted that the foregoing explanation of the auxiliary positioning device embodiment for search and rescue under landslides also applies to the auxiliary positioning method for search and rescue under landslides in this embodiment, and will not be repeated here.

[0090] The following detailed description of an embodiment of this application is based on a specific example.

[0091] Figure 4 This is a schematic diagram illustrating the actual working arrangement of one embodiment of this application. Figure 4 As shown, the actual working arrangement includes: 8-landslide surface, 9-ground penetrating radar receiver, 10-ground penetrating radar transmitter, 11-landslide surface, 12-transmitted electromagnetic waves, 13-reflected electromagnetic waves, 14-auxiliary positioning device and 15-ground.

[0092] First, personnel working in areas at risk of landslides wear auxiliary positioning devices 14 with the aid of donning and doffing devices 7 during their daily work. If a landslide occurs and buries a worker under the landslide mass, the auxiliary positioning device 14 will be buried along with the worker.

[0093] Next, during the search and rescue of workers buried under the landslide, the ground-penetrating radar transmitter 10 and the ground-penetrating radar receiver 9 were respectively positioned at appropriate locations in the search and rescue area on the landslide surface 8, emitting electromagnetic waves into the landslide. When the emitted electromagnetic waves 12 passed through the auxiliary positioning device, part of them were absorbed by the middle layer material 2, and part of them were reflected to reach the ground-penetrating radar receiver 9.

[0094] Finally, the ground-penetrating radar collects, saves, and processes the received reflected electromagnetic wave data 13 to obtain an electromagnetic wave intensity profile. By observing the electromagnetic wave intensity profile, abnormal areas of decreased electromagnetic wave intensity can be identified, which are the possible locations of the auxiliary positioning device 14 under the landslide body, and thus the possible locations of workers buried under the landslide body.

[0095] The auxiliary positioning method for landslide search and rescue proposed in this application can create an abnormal area for detection under the landslide using absorbing materials, sound wave emitting devices, and light wave emitting devices. This provides a positioning target for ground detection devices, giving ground detection and rescue a clear positioning direction and significantly improving positioning accuracy and efficiency. This solves the problems of related technologies where landslide positioning technology is only applicable to open outdoor scenes or quiet environments, or where the usage conditions are relatively harsh. The limited application environment restricts the scope of landslide positioning technology, making it difficult to accurately and effectively locate trapped personnel in complex environments and failing to meet the actual needs of landslide positioning technology in rescue operations.

[0096] Figure 5 A schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device may include:

[0097] The memory 501, the processor 502, and the computer program stored on the memory 501 and capable of running on the processor 502.

[0098] When the processor 502 executes the program, it implements the auxiliary positioning method for search and rescue under landslides provided in the above embodiments.

[0099] Furthermore, electronic devices also include:

[0100] Communication interface 503 is used for communication between memory 501 and processor 502.

[0101] The memory 501 is used to store computer programs that can run on the processor 502.

[0102] The memory 501 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk storage device.

[0103] If the memory 501, processor 502, and communication interface 503 are implemented independently, then the communication interface 503, memory 501, and processor 502 can be interconnected via a bus to complete communication between them. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 5 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0104] Optionally, in a specific implementation, if the memory 501, processor 502, and communication interface 503 are integrated on a single chip, then the memory 501, processor 502, and communication interface 503 can communicate with each other through an internal interface.

[0105] Processor 502 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of this application.

[0106] This application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described auxiliary positioning method for search and rescue under a landslide.
