DETAILED DESCRIPTION

[0008] To make the objectives, technical solutions, and advantages of the embodiments of the present application (hereinafter referred to as the embodiments) more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0009] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0010] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0011] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0012] In addition, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0013] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0014] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0015] Based on the above statement, as introduced in the background technology, some transportation vehicles are currently designed with luggage compartments with larger volumes. This structural feature may cause people or animals to accidentally enter the transportation vehicle during docking.

[0016] For example, consider buses. Operating buses generally use large, electrically operated luggage compartment doors. During daily operations or breaks, passengers may rest in the luggage compartment for convenience or enter to retrieve luggage. However, since the driver lacks real-time visibility into the luggage compartment's movements, they may unknowingly close the door, trapping passengers and potentially causing accidents.

[0017] It is worth noting that the transportation vehicles in this embodiment, in addition to the aforementioned passenger vehicles, may also be freight trucks, ground handling vehicles, and special vehicles. For example, freight trucks are often equipped with large cargo compartments, which may attract people to rest during loading and unloading or when the vehicle is parked, or people may be trapped in them due to accidents.

[0018] Based on the discovery of the above technical problems, the following technical solutions are proposed after creative work to solve or improve the above problems. It should be noted that the defects existing in the solutions in the above prior art are the results obtained after practice and careful study. Therefore, the discovery process of the above problems and the solutions proposed in the embodiments of this application for the above problems below should be regarded as contributions to this application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0019] In view of this, this embodiment provides a means of transportation. Figure 1 As shown, the means of transport includes an alarm device 12 and a luggage compartment 11, in which a rescue device 13 is provided; the alarm device 12 is communicatively connected with the rescue device 13; the rescue device 13 is used to respond to the user's rescue operation and send a distress signal to the alarm device 12; the alarm device 12 is used to send an alarm signal upon receiving the distress signal.

[0020] In this way, by utilizing the distress device 13 provided in the luggage compartment 11 to transmit a distress signal to the outside world, the outside world can promptly sense the trapped persons in the luggage compartment 11, thereby reducing the probability of occurrence of safety accidents.

[0021] In this embodiment, the alarm device 12 can be implemented based on the on-board computer. When the distress device 13 in the luggage compartment responds to the user's distress operation and sends a distress signal, the on-board computer will receive the distress signal in the first time and quickly send out an alarm signal.

[0022] Furthermore, the distress call device 13 can be a trigger button installed in a conspicuous and easily accessible location within the luggage compartment 11. Furthermore, the trigger button can be clearly labeled (e.g., "SOS" or a similar design) to ensure that trapped individuals can quickly identify and use it. In actual use, the trigger button may also be equipped with a constant light or other light source to attract the user's attention even in low-light environments such as the luggage compartment 11.

[0023] When the user presses the distress device 13, the circuit inside the trigger button is triggered, generating and sending a distress signal to the alarm device 12. It should be understood that the distress signal can be in the form of an electrical signal, such as a high-level pulse signal or other forms of communication signals, depending on the communication protocol between the alarm device 12 and the distress device 13.

[0024] In addition, considering that in a busy traffic environment, if the means of transport is in an abnormal driving state due to the occupants being trapped in the luggage compartment 11 (for example, the driver may be preparing to pull over or perform emergency braking), if the information is not conveyed to the outside world in an obvious manner, the surrounding vehicles and pedestrians may find it difficult to judge its driving state and thus fail to take appropriate avoidance or assistance measures.

[0025] In view of this, if Figure 2 As shown, the transport further includes hazard warning lights 14 in communication with the warning device 12; The alarm device 12 is further configured to control the hazard warning light 14 to emit a hazard warning signal upon receiving a distress signal.

[0026] In this embodiment, the hazard warning lights 14 may be flashing lights or other highly visible light sources mounted on the exterior of the vehicle. These devices are typically mounted in conspicuous locations such as the top, sides, or rear of the vehicle so that they can be observed from any angle by surrounding vehicles or pedestrians.

[0027] It should be understood that the luggage compartment 11 is usually located far away from the cab. When the driver is driving normally or temporarily leaving the cab, it is difficult for him to directly detect whether an emergency situation such as a person being trapped has occurred in the luggage compartment 11. Therefore, how to promptly alert the driver has become a technical problem that needs to be solved urgently.

[0028] In view of this, the alarm device 12 is located in the cab of the transport vehicle; The alarm device 12 includes at least one of a light alarm module and a sound alarm module, the light alarm module is used to emit a light warning signal, and the sound alarm module is used to emit a sound warning signal; The alarm signal includes at least one of a light warning signal and a sound warning signal.

[0029] It should be understood that the specific form of the light alarm module may include, but is not limited to, an indicator light mounted on the dashboard or a specific icon on the display screen 15. Upon receiving the distress signal, the alarm device 12 sends a control command to the light alarm module. Upon receiving the command, the light alarm module immediately illuminates or flashes a specific light warning signal. For example, the light warning signal may be a continuously illuminated SOS symbol or a regularly flashing (e.g., for 10 seconds), or other conspicuous red or yellow warning light.

[0030] In this embodiment, the sound alarm module is another device installed in the vehicle's cab. Its function is to transmit a distress signal from the luggage compartment 11 to the driver by emitting an audible warning signal. The specific form of the sound alarm module may include, but is not limited to, an electric horn or other types of audio equipment. Similar to the light alarm module, the sound alarm module is also triggered when the alarm device 12 receives a distress signal.

[0031] Upon receiving the command, the audio alarm module immediately plays a preset audio warning signal. For example, the audio warning signal can be a continuous or intermittent alarm sound (for example, lasting 10 seconds), or a voice message with a clear prompt (for example, "Someone in the luggage compartment 11 is calling for help. Please respond immediately").

[0032] In practice, it has been found that during actual use of a vehicle, the emergency device 13 in the luggage compartment 11 may be mistakenly triggered by external factors. For example, luggage may accidentally touch the emergency button during transportation, causing the alarm device 12 to receive a false emergency signal. Alternatively, the shaking of the vehicle during operation may be transmitted to the luggage, causing it to move and trigger the emergency device 13. For the driver, it is difficult to determine the authenticity and urgency of the alarm based solely on the light or sound warning signal, which may lead to unnecessary stops, inspections, or other operations.

[0033] In view of this, if Figure 3 As shown, the transport further includes a display screen 15 in communication with the alarm device 12; An image acquisition device 16 is also provided in the luggage compartment 11 and is in communication with the alarm device 12; The alarm device 12 is further configured to display the cabin image captured by the image capture device 16 on the display screen 15 upon receiving a distress signal.

[0034] As an optional embodiment, the alarm device 12 may include a monitoring module, which controls the image acquisition device 16. Alternatively, a monitoring system may be running in the alarm device 12, which controls the image acquisition device 16.

[0035] In this way, the driver can visually view the actual situation inside the luggage compartment 11 in the cab, and thus quickly determine whether the alarm is caused by a real person being trapped or by other false triggering factors.

[0036] In practice, we've also discovered that in actual transportation scenarios, the space within the luggage compartment 11 is often quite compact. This is especially true when loaded with a large amount of luggage or cargo. This can obstruct the distress signal 13, preventing the trapped person from seeing it and delaying the ability to send a distress signal. Furthermore, when the luggage compartment 11 is heavily stacked, even if a person is trapped, it may be difficult to reach the alarm device 12 due to the obstruction, further increasing the difficulty of calling for help. Of course, when there's less luggage, or if the trapped object is an animal, the alarm device 12 also fails to trigger.

[0037] The study further found that the luggage in the luggage compartment 11 usually does not move significantly, but people or animals trapped therein may move significantly due to panic. Based on this finding, an image acquisition device 16 is also provided in the luggage compartment 11, which is in communication with the alarm device 12; The alarm device 12 is also used to determine the degree of change in the field of view of the image acquisition device 16 after the door of the luggage compartment 11 is closed; If the degree of change is greater than the abnormal threshold, an alarm signal will be issued.

[0038] It can be understood that when a person is trapped in the luggage compartment 11, their movements will inevitably cause changes in the field of view of the image capture device 16. For example, body movement or limb motions. Therefore, even if the trapped person is unable to reach the distress device 13 due to luggage obstructing their access, these dynamic features can still be captured by the image capture device 16 and transmitted to the alarm device 12, thereby triggering the alarm process.

[0039] As an optional embodiment, the alarm device 12 can perform pixel-level comparison on the two frames of images to extract the difference area; and quantify the degree of change based on the area, displacement distance or other relevant parameters of the difference area.

[0040] In practice, it has also been found that, during actual use of a vehicle, the light and sound alarm modules located in the cab can effectively alert the driver to distress signals within the luggage compartment 11. However, it should be noted that these modules are typically only triggered when an abnormality occurs within the luggage compartment 11 and rarely function during daily operation. Therefore, even if these modules malfunction—for example, if the light fails to illuminate or the sound fails to sound—the driver may not be aware of it, which in turn reduces the overall reliability of the system.

[0041] For example, if the indicator light of the light alarm module is damaged due to long-term non-use, or the speaker of the sound alarm module fails due to dust accumulation, when an emergency such as people being trapped in the luggage compartment 11 actually occurs, the driver may not be able to receive the alarm information in time.

[0042] In view of this, if Figure 4 As shown, the transport vehicle further includes a whistle device 17 in communication with the alarm device 12; The alarm device 12 is also used to count the number of times the distress signal is sent; If the number of transmissions is greater than the threshold, the whistle device 17 is controlled to sound the whistle according to a preset rhythm.

[0043] It should be understood that the whistle device 17 is one of the most frequently used devices on a vehicle. Its function and status are usually monitored and maintained by the driver, and therefore it has high reliability and stability. Even if the light alarm module or the sound alarm module malfunctions due to long-term non-use, the whistle device 17 can still function normally and transmit a distress signal.

[0044] Therefore, when the distress signal device 13 in the luggage compartment 11 is triggered multiple times, the alarm device 12 counts that the number of distress signal transmissions has exceeded the threshold and activates the whistle device 17 to emit a continuous alarm sound. This design provides the driver with an additional means of providing distress information in the event that the light alarm module or the sound alarm module fails, ensuring that information transmission in an emergency is not interrupted.

[0045] It should also be noted that a preset rhythm can be expressed as a fixed whistle timing sequence, such as a series of short whistles or intermittent alternations of long and short whistles. For example, a preset rhythm could be designed as a "three short, one long" cycle, with three short whistles followed by a long whistle, and then repeating this cycle. Furthermore, the preset rhythm can be adjusted based on the time interval, for example, by setting a fixed interval (such as 1 or 2 seconds) between each whistle to ensure a clear rhythmic feel.

[0046] It should also be understood that the design of a preset rhythm typically employs a pattern distinct from that of a typical horn sound. For example, a single, continuous horn or irregular, random horn sounds should be avoided, thereby more easily attracting the driver's attention. Furthermore, a regular horn sound is highly recognizable, allowing the driver to quickly determine that the vehicle is in distress, rather than a typical warning or prompt signal.

[0047] In summary, the above embodiment transmits a distress signal to the outside world, prompting people to come to the rescue. When the luggage compartment door 11 is opened to rescue the trapped person, the alarm device 12 receives the luggage compartment door opening signal, and then switches the screen 15 back to its original state and turns off the light alarm module and the sound alarm module.

[0048] Based on the same inventive concept as the transportation vehicle provided in this embodiment, this embodiment also provides a distress warning method, which is applied to the alarm device 12 of the transportation vehicle. The alarm device 12 includes a processor and a memory. The memory stores a computer program. The processor implements the distress warning method provided in this embodiment by reading and executing the computer program corresponding to the above embodiments in the memory.

[0052] The communication unit is configured to transmit and receive data via a network. In some embodiments, the network may include a wired network, a wireless network, a fiber optic network, a telecommunications network, an intranet, the Internet, a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a metropolitan area network (MAN), a wide area network (WAN), a public switched telephone network (PSTN), a Bluetooth network, a ZigBee network, or a near field communication (NFC) network, or any combination thereof. In some embodiments, the network may include one or more network access points. For example, the network may include a wired or wireless network access point, such as a base station and / or a network switching node, through which one or more components of the service request processing system may connect to the network to exchange data and / or information.

[0053] The processor may be an integrated circuit chip having signal processing capabilities, and the processor may include one or more processing cores (e.g., a single-core processor or a multi-core processor). By way of example only, the processor may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction set processor (ASIP), a graphics processing unit (GPU), a physical processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction set computer (RISC), or a microprocessor, or any combination thereof.

[0055] The distress signal is sent by the distress device 13 in response to the user's distress operation.
