Description

Technical Field

[0001] This invention relates to the respiratory system, specifically to an accessible graphic emergency call system for deaf and mute individuals. Background Technology

[0002] Current graphic and text-based emergency call systems for the deaf and mute typically include a basic icon or text-based SOS interface and support the transmission of preset SOS signals via simple buttons. For example, patent publication number CN107818659A discloses an intelligent emergency call system and method. This intelligent emergency call system includes a vital signs monitoring module, a control system, and an alarm module. The vital signs monitoring module monitors the wearer's vital signs data and transmits or shares the monitoring results with the control module and the alarm module. When the vital signs data detected by the vital signs monitoring module falls within a pre-set alarm data range, the control module controls the alarm module to issue an alarm. The intelligent emergency call system disclosed in this invention automatically monitors the wearer's vital signs data and issues alarms promptly according to the set range, enabling timely assistance for patients with sudden abnormal vital signs and preventing sudden death.

[0003] Existing graphic and text-based emergency call systems often only express needs through icons or simple text, failing to convey specific emergency needs (such as fires, medical emergencies, etc.) and scene signals, making it difficult for rescuers to quickly understand the user's specific distress call intentions. Furthermore, existing graphic and text-based emergency call systems typically transmit distress signals at a fixed frequency or in a single transmission, lacking a dynamic adjustment mechanism when the signal is not responded to promptly. Moreover, the distress signals in existing systems are usually single location signals or simple distress signals, failing to incorporate multiple signal sources such as the user's personalized distress request, location signals, and level of deafness, resulting in incomplete signals and affecting rescue decisions. Therefore, this invention provides an accessible graphic and text-based emergency call system for deaf and mute individuals. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an accessible graphic and text-based emergency call system for deaf and mute individuals. It solves the technical problems mentioned in the background art by generating and encapsulating various distress signals and dynamically transmitting them in multiple stages.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An accessible graphic emergency call system for deaf and mute individuals, the system comprising:

[0007] The first distress signal generation module is used to receive the first distress signal sent by a silent distress caller; wherein, the first distress signal is characterized as a distress signal triggered by a touch sensor with one key.

[0008] The first distress signal response module is used to trigger a number of distributed matching requests in parallel after responding to the first distress signal; the number of matching requests includes: a first matching request, a second matching request, and a third matching request;

[0009] The distress signal generation module is used to respond to distributed matching requests and generate several distributed distress signals.

[0011] The data packet transmission module is used to transmit the distress data packet according to the current transmission frequency;

[0012] If the distress data packet is responded to within the current preset time period, a distress response signal is generated and displayed graphically; otherwise, the process proceeds to the next transmission phase, and the distress data packet is transmitted within the next preset time period at an increased multiple of the transmission frequency.

[0013] In this process, the transmission frequency of each transmission phase is a multiple of the previous transmission frequency, and the preset duration of each transmission phase is increased by a increment of the preset duration that is greater than the previous preset duration.

[0014] The expression for the distress data packet transmission phase is:

[0015] f n =k n-1 ·f1 and And Δt n =Δt1+(n-1)·Δt inc ;

[0016] Among them, f n Let f1 be the transmission frequency of the nth stage, k represent the multiplier of the transmission frequency, and f1 be the initial first transmission frequency, characterized by transmitting once every T1 seconds; T n Let Δt be the launch interval time for the nth stage. n This represents the preset duration of the nth stage; for example, k=2 indicates that the transmission frequency doubles in each stage, Δt inc The preset time increment for each stage.

[0019] S1-2. After receiving the touch signal, mark the touch signal as an emergency distress event; the emergency distress event includes: an emergency distress tag and a device identifier;

[0020] S1-3. Process the marked emergency distress events to generate the first distress signal.

[0021] In some embodiments, the data processing of the tagged emergency distress events includes:

[0022] S1-3-1. Encapsulate the marked emergency distress event to obtain an encapsulated signal; S1-3-2. Encode the encapsulated signal to obtain a first distress signal with a standard format.

[0023] In some embodiments, the step of the distress signal generation module generating several distress signals includes:

[0024] S3-1. Respond to the first matching request and invoke the first matching instruction to generate a default distress signal;

[0025] S3-2. Responding to the second matching request, invoke the second matching instruction to generate a user distress signal;

[0026] S3-3. Respond to the third matching request and invoke the third matching instruction to generate a location distress signal;

[0027] S3-4. Define the default distress signal, user distress signal, and location distress signal as a distributed set of distress signals.

[0028] In some embodiments, responding to the first matching request and invoking the first matching instruction to generate a default distress signal includes:

[0029] S3-1-1. Obtain the preset deafness level signal of the silent distress caller; S3-1-2. Match the corresponding distress priority according to the preset deafness level signal of the silent distress caller;

[0030] S3-1-3. Based on the matched distress priority, generate and label the signal as a default distress signal.

[0031] In some embodiments, invoking the second matching instruction to generate a user distress signal includes:

[0032] S3-2-1. According to the second matching instruction, enter the graphic and text-based SOS interface;

[0033] S3-2-2. On the graphic and text-based distress call interface, several graphic and text-based distress call options are displayed through a distributed graphic and text window; the graphic and text-based distress call options include: common distress call types and custom distress call types;

[0034] S3-2-3. Select a graphic / text distress signal option to confirm the second distress signal;

[0035] S3-2-4. Based on the mapping relationship between the second distress signal and the preset distress signal, match the preset user distress signal in the distress signal set.

[0036] In some embodiments, the invocation of the third matching instruction to generate a location distress signal includes:

[0037] S3-3-1. Generate a location acquisition request based on the third matching instruction;

[0038] S3-3-2. Based on the location acquisition request, call the positioning module to obtain the real-time location of the current silent distress caller; wherein, the positioning module is pre-installed with GPS positioning, Wi-Fi positioning or cellular network-based positioning program;

[0039] S3-3-3: Extract the geographic coordinates and current timestamp from the real-time location to obtain the spatiotemporal signal of the silent distress caller;

[0040] S3-3-4. Based on the spatiotemporal signals of the silent distress caller, generate and standardize them into a location distress signal.

[0041] In some embodiments, the step of the signal encapsulation module generating a distress data packet includes:

[0042] S4-1. Collect default distress signals, user distress signals, and location distress signals;

[0043] S4-2. Perform secondary standardization and encapsulation processing on the default distress signal, user distress signal, and location distress signal;

[0044] S4-3. The default distress signal, user distress signal and location distress signal that have undergone secondary standardization and encapsulation are finally encapsulated to generate the distress data packet.

[0045] This invention provides an accessible graphic emergency call system for deaf and mute individuals, which has the following beneficial effects:

[0046] The graphic and text-based distress signal system of this invention can not only generate distress signals based on user-defined criteria, but also combine preset default distress signals (such as emergency priority) and location signals to form a multi-signal encapsulated distress data packet. It can provide a more comprehensive and accurate distress signal than a single signal, allowing rescuers to quickly obtain the specific situation, urgency level, and location of the silent distress caller from the distress signal, enabling a more efficient rescue response.

[0047] Furthermore, after generating a distress data packet, this system prioritizes transmitting distress signals in a low-energy manner by gradually increasing the transmission frequency and signal strength in a multi-stage manner, and gradually increases the strength and frequency when there is no response.

[0048] By controlling the transmission frequency and preset duration in multiple stages, the signal strength is gradually increased in each stage. This ensures that the distress signal can cover the system at a higher frequency and for a longer period of time in the event of no response, allowing the system to maintain a continuous distress signal with the lowest possible strength and frequency when there is no response. When entering the next stage, the system only increases the transmission strength when necessary, conserving energy while ensuring effective distress signaling, thereby extending system usage time and increasing the user's chances of survival.

[0049] Furthermore, this system allows users to select common or custom distress call types via a graphical interface and matches distress call priorities based on the level of deafness or muteness of the user making the silent distress call. This improvement enables the system to prioritize urgent distress requests in rescue decision-making, significantly enhancing response efficiency. Attached Figure Description

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1: Please refer to Figures 1 to 4 This invention provides an accessible graphic emergency call system for deaf and mute individuals, comprising:

[0056] The first distress signal generation module is used to receive the first distress signal sent by a silent distress caller; wherein, the first distress signal is characterized as a distress signal triggered by a touch sensor with one key.

[0057] The first distress signal response module is used to trigger a number of distributed matching requests in parallel after responding to the first distress signal; the number of matching requests includes: a first matching request, a second matching request, and a third matching request;

[0058] The distress signal generation module is used to respond to distributed matching requests and generate several distributed distress signals.

[0059] The signal encapsulation module is used to encapsulate several distributed distress signals to generate distress data packets;

[0060] The data packet transmission module is used to transmit the distress data packet according to the current transmission frequency;

[0061] If the distress data packet is responded to within the current preset time period, a distress response signal is generated and displayed graphically; otherwise, the process proceeds to the next transmission phase, and the distress data packet is transmitted within the next preset time period at an increased multiple of the transmission frequency.

[0062] In this process, the transmission frequency of each transmission stage is a multiple of the previous transmission frequency, and the preset duration of each transmission stage is increased by a increment greater than the previous preset duration.

[0063] That is, increasing the frequency by a factor can increase the signal transmission density, while the second preset duration being greater than the first preset duration can ensure that there is enough time to wait for a response in the case of high-frequency transmission.

[0064] Specifically, after receiving a distress signal from a silent user, the system packages the distress signal into a distress data packet and transmits the packet at a first transmission frequency, for example, once every 30 seconds. Simultaneously, the system starts a first preset timer, for example, set to 60 seconds, to monitor whether a response is received within this time. Then, it continuously monitors whether the distress data packet receives a response within the first preset time.

[0065] If a distress response is received within the first preset time period, the transmission of distress data packets will stop, a "distress response signal" will be generated, and the response status will be displayed on the interface with graphics and text.

[0066] If no response is received within the first preset time period, the system enters the second preset time period and automatically switches to a higher second transmission frequency to continue transmitting distress data packets.

[0067] The second transmission frequency can be a multiple of the first transmission frequency, thereby increasing the signal transmission frequency. For example, if the first transmission frequency is once every 30 seconds, the second transmission frequency can be set to once every 15 seconds (i.e., twice the first transmission frequency).

[0068] The second preset duration can be set to a longer duration to ensure sufficient time to wait for a response in the case of high-frequency transmission.

[0069] Furthermore, if no response is received within the second preset time period, the system can re-enter a new transmission frequency and preset time period, further increasing the transmission frequency. This can be understood as entering the nth stage of the transmission process. For example, the frequency can be increased to once every 10 seconds (3 times the first transmission frequency) to maximize the signal coverage density and response probability.

[0070] Furthermore, the transmission phase of the aforementioned distress data packet can be described as follows:

[0071] f1 is the initial first transmission frequency, that is, one transmission every T1 seconds, Δt n This represents the preset duration of the nth stage, where k represents the multiplier of the transmission frequency; and the transmission frequency f in the nth stage... n Transmission interval T n and preset duration Δt n It can be uniformly represented as:

[0072] f n =k n-1 ·f1 and And Δt n =Δt1+(n-1)·Δt inc ;

[0073] Among them, f n Let T be the transmission frequency of the nth stage. n Let Δt be the launch interval time for the nth stage. n The preset duration for the nth stage, k is the multiplier for increasing the transmission frequency, for example, k = 2 means the transmission frequency doubles in each stage, Δt inc The preset time increment for each stage.

[0074] This embodiment improves the probability of receiving distress signals by gradually increasing the transmission frequency and extending the preset duration in stages, thereby increasing the density and coverage time of signal transmission when no response is received.

[0075] In this embodiment, the system uses a multi-stage, progressively increasing transmission frequency and signal strength control to prioritize transmitting distress signals in a low-energy-consumption manner, gradually increasing the strength and frequency when there is no response. This means that by controlling the transmission frequency and preset duration in multiple stages, the system progressively increases the signal strength at each stage, ensuring that the distress signal can cover the system at a higher frequency and for a longer period even without a response. This allows the system to maintain continuous distress communication at the lowest possible strength and frequency when there is no response. When entering the next stage, the system only increases the transmission strength when necessary, conserving energy while ensuring effective distress communication, thereby extending system lifespan and increasing the user's survival probability.

[0076] In this embodiment, the step of the first distress signal generation module generating the first distress signal includes:

[0077] S1-1. Obtain the touch signal actively pressed by the silent distress caller; for example, receive the touch signal of the silent distress caller on the corresponding graphic distress call device, and identify the touch signal as the initial trigger signal of the silent distress caller's intention to seek help.

[0078] S1-2. After receiving the touch signal, mark the touch signal as an emergency distress event; the emergency distress event includes: an emergency distress tag (i.e., marking it as a distress type) and a device identifier;

[0079] In this embodiment, the touch signal is marked using time-stamping technology and labeled with a "distress intent" tag to identify the touch signal as an emergency distress event.

[0080] S1-3. Process the marked emergency distress events to generate the first distress signal.

[0081] This embodiment enables the system to quickly detect emergencies by recognizing and marking touch signals.

[0082] Furthermore, steps S1-3 also include:

[0083] S1-3-1. Encapsulate the marked emergency distress event to obtain an encapsulated signal; encapsulate the timestamp, distress identifier, and device identifier as parameters; wherein, the device identifier refers to the device ID or device type that triggered the distress signal, such as a mobile phone, smart bracelet, special distress button, etc., thereby providing one type of identifier signal for the silent distress caller and broadening the signal channels for distress progress.

[0084] S1-3-2. Encode the encapsulated signal to obtain a first distress signal with a standard format; thereby ensuring that all parameters in the first distress signal conform to the system encoding standard and ensuring data consistency.

[0085] Furthermore, the step of generating several distress signals by the distress signal generation module in Embodiment 1 includes:

[0086] S3-1. Respond to the first matching request and invoke the first matching instruction to generate a default distress signal;

[0087] S3-2. Responding to the second matching request, invoke the second matching instruction to generate a user distress signal;

[0088] S3-3. Respond to the third matching request and invoke the third matching instruction to generate a location distress signal;

[0089] S3-4. Define the default distress signal, user distress signal, and location distress signal as a distributed set of distress signals.

[0090] This embodiment enables the system to respond to different distress requests in parallel through distributed matching requests and the generation of multiple types of distress signals, thereby enhancing the diversity and coverage of signal transmission and ensuring the full expression of the user's distress intentions.

[0091] Example 2, which differs from Example 1 in that it also discloses:

[0092] Step S3-1 includes:

[0093] S3-1-1. Obtain the preset deafness level signal of the silent distress caller; extract the deafness level signal from the preset data of the silent distress caller, wherein the deafness level signal reflects the degree of deafness or impairment in hearing and speech of the silent distress caller.

[0094] S3-1-2. Based on the preset deafness level signal of the silent distress caller, match the corresponding distress priority; the matching ensures that the urgency of subsequently generated distress signals matches the deafness level requirements of the silent distress caller. For example, silent distress callers with higher-level deafness signals will be assigned a higher distress priority. Of course, the matching relationship between the deafness level signal and the distress priority can be a simple one-to-one mapping, or it can be a comprehensive index that can be obtained by weighting different degrees of hearing and speech impairment to obtain a one-to-one matching distress priority. That is, this distress priority is used for subsequent allocation of rescue resources.

[0095] S3-1-3. Based on the matched distress priority, generate and label the default distress signal; wherein, the specific content of generating the default distress signal includes: extracting the emergency distress tag, distress priority identifier, and other distress signals in the aforementioned emergency distress event; and packaging the default distress signal involves standardizing and packaging the specific content of the generated default distress signal so that it can be packaged and transmitted together with other distress signals in subsequent steps.

[0096] This embodiment obtains the deafness level signal of users who are silently calling for help and generates a default distress signal with matching priority, enabling the system to flexibly allocate rescue resources according to different needs, which significantly improves rescue efficiency.

[0097] Step S3-2 includes:

[0098] S3-2-1. According to the second matching instruction, enter the graphic and text-based SOS interface;

[0099] S3-2-2. On the graphic and text-based SOS interface, several graphic and text-based SOS options are displayed through a distributed graphic and text window. The graphic and text-based SOS options include: common SOS types and custom SOS types. Common SOS types include: medical emergency, fire, gas leak, etc. Custom SOS types can be customized and selected according to the needs of silent SOS users and different models.

[0100] S3-2-3. Select a graphic / text distress call option to determine the second distress signal; Silent distress call users select one or more graphic / text distress call options in the graphic / text distress call interface, record the silent distress call user's selection and determine it as the second distress signal, the second distress signal represents the silent distress call user's specific distress intention.

[0101] S3-2-4. Based on the mapping relationship between the second distress signal and the preset distress signal, match the preset user distress signal in the distress signal set;

[0102] In this embodiment, the distress signal set refers to a pre-defined collection of various standardized and encapsulated distress signals. These pre-defined distress signals are defined based on common distress scenarios and needs, and a mapping relationship is established with options in the graphic and text-based distress call interface (such as medical emergency, fire, gas leak, etc.) to ensure quick matching of the appropriate distress signal after user selection. Specifically:

[0103] Composition of a distress signal set: A distress signal set contains various types of distress signals, each representing a specific distress request. For example:

[0104] Medical emergency signals

[0105] Fire distress signal

[0106] Gas leak distress signal

[0107] alarm distress signal

[0108] Customizable distress signals (can be customized to user needs)

[0109] This embodiment displays common and customizable distress options through a graphical distress interface, enabling silent distress callers to quickly select or define specific distress types, ensuring personalized delivery and rapid response of distress signals.

[0110] Step S3-3 includes:

[0111] S3-3-1. Generate a location acquisition request according to the third matching instruction; the location acquisition request is generated to activate the positioning process and ensure that the system starts collecting real-time location data of users who are silently calling for help.

[0112] S3-3-2. Based on the location acquisition request, call the positioning module to obtain the real-time location of the current silent distress caller; wherein, the positioning module is pre-installed with GPS positioning, Wi-Fi positioning or cellular network-based positioning program;

[0113] The positioning module can include multiple positioning methods (such as GPS, Wi-Fi or cellular network positioning) to ensure that location information can be provided in different environments, so that the system can flexibly select the most suitable positioning method to obtain accurate geographical location data.

[0114] S3-3-3: Extract the geographic coordinates and current timestamp from the real-time location to obtain the spatiotemporal signal of the silent distress caller;

[0115] Geographic coordinates identify a user's location, while a timestamp provides the specific time the location was acquired. These two pieces of information form a "spatiotemporal signal" for the user, ensuring that location information is clearly identified in both time and space.

[0116] S3-3-4. Based on the spatiotemporal signals of the silent distress caller, generate and standardize them into a location distress signal;

[0117] Specifically, S3-3-3 can use a uniform data encapsulation format (such as JSON or Protobuf) to integrate geographic coordinates and timestamps into location signal data packets. Each field in the data packet is arranged in a standard format.

[0118] Furthermore, the step of the signal encapsulation module generating a distress data packet includes:

[0119] S4-1. Collect default distress signals, user distress signals, and location distress signals;

[0120] Specifically, the system collects different types of distress signals generated from the execution results of distributed matching requests. These include:

[0121] Default SOS signal: A SOS signal generated based on the preset deafness level of the silent user, with a corresponding emergency SOS tag.

[0122] User distress signal: The signal generated by the silent distress user's selection of the graphic distress option in the graphic distress interface, representing the specific distress message.

[0123] Location distress signal: A signal generated based on the real-time geographic location and timestamp signal obtained by the positioning module, used to identify the location of the requester.

[0124] The signals mentioned above are generated from different matching requests and are collected together for further processing.

[0125] S4-2. Perform secondary standardization and encapsulation processing on the default distress signal, user distress signal, and location distress signal;

[0126] Specifically, the collected distress signals undergo secondary normalization and encapsulation to ensure that the three different signals meet transmission requirements in terms of format and data consistency. The secondary normalization and encapsulation process includes:

[0127] Standardized format: Standardize the encoding, field length, data type, etc. of each signal to ensure that all signals are structurally consistent.

[0128] Unified labeling: Add formatted emergency labels, signal type identifiers, etc. to various signals, enabling the system to quickly identify the purpose and category of the signal.

[0129] Eliminate redundancy: Check for redundant signals in the signal data to ensure that the data is concise and clear, thereby improving transmission efficiency.

[0130] S4-3. The default distress signal, user distress signal and location distress signal that have undergone secondary standardization and encapsulation are finally encapsulated to generate the distress data packet.

[0131] Specifically, the system performs final encapsulation on the distress signal that has undergone secondary standardization and encapsulation, generating a complete distress data packet. The final encapsulation process includes:

[0132] Encapsulate distress signals: Integrate the default distress signal, user distress signal, and location distress signal into the same data packet, and add header signals (such as data packet ID, transmission time, etc.) to ensure the uniqueness and integrity of the signal packet.

[0133] Add an emergency flag: Add an emergency distress flag to the data packet so that the rescue center can quickly identify and prioritize the packet when it is received.

[0134] Generate data packet structure: Pack the distress data packet into a format that conforms to the communication protocol, ensuring that the data packet does not have errors during transmission and unpacking.

[0135] This embodiment generates a unified distress data packet by collecting different distress signals, performing secondary standardization and encapsulation, and finally encapsulating the packet. This ensures data consistency and security during transmission and improves the accuracy and efficiency of the rescue response.

[0136] In this embodiment, the text and image distress signal system can not only generate distress signals based on user-defined criteria, but also combine preset default distress signals (such as emergency priority) and location signals to form a multi-signal encapsulated distress data packet. It can provide a more comprehensive and accurate distress signal than a single signal, allowing rescuers to quickly obtain the specific situation, urgency level, and location of the silent distress caller from the distress signal, enabling a more efficient rescue response.

[0137] In summary, this invention significantly improves the success rate and response speed of silent distress callers in emergency situations through a mechanism of distributed distress signal generation and multi-stage gradual increase in transmission frequency.
