Description

Technical Field

[0001] The present invention relates to the respiratory system, and more particularly to a barrier-free graphic call-for-help system for deaf-mute people. Background Art

[0002] Current graphic call-for-help systems for deaf-mute people usually include basic icon or text help-seeking interfaces and support transmitting preset help-seeking signals through simple buttons. For example, the patent publication number is: CN107818659A, which discloses an intelligent call-for-help system and an intelligent call-for-help method. The intelligent call-for-help system includes a physical sign monitoring module; a control system; an alarm module; the physical sign monitoring module monitors the physical sign data of the wearer and transmits or shares the monitoring results with the control module and the alarm module; when the physical sign data monitored by the physical sign monitoring module is within the pre-set alarm data range, the control module controls the alarm module to issue an alarm. The intelligent call-for-help system disclosed by the present invention can automatically monitor the physical sign data of the wearer and issue an alarm in a timely manner according to the set range, so that sudden patients with abnormal physical sign data can be rescued in a timely manner and the occurrence of sudden death can be prevented.

[0003] The graphic call systems in the prior art often can only represent needs through icons or simple texts, and cannot express the specific emergency needs (such as fires, medical treatment, etc.) and scene signals of users. It is difficult for rescue personnel to quickly understand the specific help-seeking intentions of users; and the existing graphic help-seeking systems usually transmit help-seeking signals at a fixed frequency or once, and when the signals are not responded to in a timely manner, there is a lack of a dynamic adjustment mechanism. And the help-seeking signals of the existing systems are usually single positioning signals or simple help-seeking signals, without combining multiple signal sources such as the personalized help-seeking content, location signals, and deaf-mute levels of users, resulting in one-sided signals and affecting rescue decisions. For this reason, the present invention provides a barrier-free graphic call-for-help system for deaf-mute people. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a barrier-free graphic call-for-help system for deaf-mute people, which solves the technical problems raised in the background art through methods such as generating and encapsulating multiple help-seeking signals and dynamically transmitting in multiple stages.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions:

[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 duration, a distress response signal is generated and displayed in text and graphics; otherwise, it enters the next transmission stage, and the distress data packet is transmitted at an increased multiple of the transmission frequency within the next preset duration;

[0013] Among them, the transmission frequency of each transmission stage is an increased multiple of the previous transmission frequency, and the preset duration of each transmission stage is greater than the previous preset duration according to the preset duration increment;

[0014] The expression of the distress data packet transmission stage is:

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

[0016] Among them, f n is the transmission frequency of the nth stage, k represents the increased multiple of the transmission frequency, f 1 is the initial first transmission frequency, characterized by transmitting once every T 1 seconds; T n is the transmission interval time of the nth stage, Δt n represents the preset duration of the nth stage; for example, k = 2 means that the transmission frequency doubles in each stage, and Δt inc is the preset duration increment added in each stage.

[0023] In some embodiments, the steps for the call signal generation module to generate several call signals include:

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

[0025] S3-2. Respond to the second matching request, and call the second matching instruction to generate a user call signal;

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

[0027] S3-4. Define the default call signal, the user call signal, and the location call signal as several distributed call signals.

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

[0029] S3-1-1. Obtain the preset deaf-mute level signal of the silent call user; S3-1-2. According to the preset deaf-mute level signal of the silent call user, match the corresponding call priority;

[0030] S3-1-3. Generate and standardize and encapsulate according to the matched call priority into a default call signal.

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

[0033] S3-2-2. In the graphic call interface, display several graphic call options through a distributed graphic window; the graphic call options include: common call types and custom call types;

[0034] S3-2-3. Select a certain graphic and text for help option to determine the second distress signal;

[0035] S3-2-4. According to 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 of these embodiments, the invoking of the third matching instruction to generate a location distress signal includes:

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

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

[0045] The present invention provides a barrier-free graphic and text for help system for the deaf-mute population, having the following beneficial effects:

[0046] The graphic and text for help system of the present invention can not only generate distress signals defined by the user himself, but also combines the preset default distress signals (such as emergency priority) and location signals to form a distress data packet with multi-signal encapsulation. It can provide a more comprehensive and accurate distress signal than a single signal, and rescue personnel can quickly obtain the specific situation, emergency level and location signal of the silent distress user from the distress signal, and make a more efficient rescue response.

[0047] After generating a distress data packet, the system uses a multi-stage transmission frequency and signal strength control that increases gradually, giving priority to transmitting the distress signal in a low-energy manner, and gradually increasing the strength and frequency in the absence of a response.

[0048] Through multi-stage transmission frequency and preset duration control, the signal strength of each stage is gradually increased to ensure that the distress signal can be covered at a higher frequency and longer time when there is no response, so that the system can continue to call for help at the lowest possible strength and frequency when there is no response. When entering the next stage, the system will increase the transmission intensity only when necessary, saving energy while ensuring effective rescue, thereby extending the system usage time and increasing the user's survival probability.

[0049] Furthermore, the system selects common or customized types of help through a graphic interface, and matches the help priority according to the deaf-mute level signal of the silent user. Through this improvement, the system can give priority to urgent help requests in rescue decision-making, significantly improving response efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Example 1: Please refer to Figures 1 to 4 The present invention provides a barrier-free graphic and text call system for deaf-mute people, comprising:

[0056] A first distress signal generating module is used to receive a first distress signal sent by a silent distress user; wherein the first distress signal is characterized as a distress signal triggered by a touch-sensitive one-button;

[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: the first matching request, the second matching request, and the third matching request;

[0058] The distress signal generation module is used to respond to the distributed matching requests to generate a number of distributed distress signals;

[0059] The signal encapsulation module is used to perform signal encapsulation on the number of distributed distress signals to generate a distress data packet;

[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 duration, a distress response signal is generated and displayed graphically; otherwise, it enters the next transmission stage, and the distress data packet is transmitted at an increased multiple of the transmission frequency within the next preset duration;

[0062] Among them, the transmission frequency of each transmission stage is an increased multiple of the previous transmission frequency, and the preset duration of each transmission stage is greater than the previous preset duration according to the preset duration increment.

[0063] That is, the increased multiple of the frequency can increase the signal transmission density, and the second preset duration being greater than the first preset duration can ensure sufficient duration for waiting for a response in the case of high-frequency transmission.

[0064] Specifically, after the system receives the distress signal of the silent distress user and packs the distress signal into a distress data packet, it transmits the distress data packet according to the first transmission frequency, for example, once every 30 seconds. At the same time, the system starts timing the first preset duration, for example, set to 60 seconds, to monitor whether a response is obtained within this time. Then, it continuously monitors whether the distress data packet is responded to within the first preset duration.

[0065] If a distress response is received within the first preset duration, the transmission of the distress data packet is stopped, and a "distress response signal" is generated and the response status is displayed graphically on the interface.

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

[0067] The second transmission frequency can be a multiple of the first transmission frequency, so as to increase 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., 2 times the first transmission frequency).

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

[0069] Further, if no response is obtained within the second preset duration, the system can enter a new transmission frequency and preset duration again to further increase the transmission frequency. It can be understood that the system enters the transmission process of the nth stage at this time. For example, the frequency is increased to once every 10 seconds (3 times the first transmission frequency) to maximize the coverage density and response probability of the signal.

[0070] Further, the transmission stage of the above distress data packet can be expressed as:

[0071] f 1 is the initial first transmission frequency, that is, it transmits once every T 1 seconds, Δt n represents the preset duration of the nth stage, and k represents the increase multiple of the transmission frequency; the transmission frequency f n , transmission interval T n and preset duration Δt n can be uniformly expressed as:

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

[0073] where, f n is the transmission frequency of the nth stage, T n is the transmission interval time of the nth stage, Δt n is the preset duration of the nth stage, k is the increase multiple of the transmission frequency. For example, k = 2 means that the transmission frequency doubles in each stage, and Δt inc is the increment of the preset duration added in each stage.

[0074] In this embodiment, by means of the mechanism of gradually increasing the transmission frequency and extending the preset duration in stages, the density and coverage time of signal transmission are increased in the case of no response, thereby effectively improving the reception probability of distress signals.

[0075] In this embodiment, the system conveys the distress signal in a low - energy - consuming manner preferentially through gradually increasing multi - stage transmission frequencies and signal intensities, and gradually increases the intensity and frequency in the case of no response. This means that the system controls through multi - stage transmission frequencies and preset time durations, gradually increasing the signal intensity in each stage, ensuring that the distress signal can cover at a higher frequency and for a longer time in the case of no response, so that the system can maintain continuous distress at the lowest possible intensity and frequency when there is no response. When entering the next stage, the system only increases the transmission intensity when necessary, saves energy on the premise of ensuring effective distress, and achieves the purpose of extending the system usage time and increasing the user's survival probability.

[0076] In this embodiment, the steps for the first distress signal generation module to generate the first distress signal include:

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

[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 label (i.e., marking it as the distress type) and a device identifier;

[0079] In this embodiment, the touch signal is marked through the time - tag technology, and the "distress intention" label is given to identify the touch signal as an emergency distress event.

[0080] S1 - 3. Perform data processing on the marked emergency distress event to generate the first distress signal.

[0081] This embodiment enables the system to quickly perceive emergencies through the recognition and marking of touch signals.

[0082] Further, step S1 - 3 also includes:

[0083] S1 - 3 - 1. Perform data encapsulation on the marked emergency distress event to obtain an encapsulated signal; encapsulate the time stamp, distress identifier, and device identifier; where the device identifier refers to the device ID or device type that triggers the distress signal, such as a mobile phone, a smart bracelet, a special distress button, etc., thereby providing one type of identification signal for the silent distress user and broadening the signal channel for the distress progress.

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

[0085] Further, the steps for the distress signal generation module in Embodiment 1 to generate a number of distress signals include:

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

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

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

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

[0090] In this embodiment, through distributed matching requests and the generation of multi-type distress signals, the system can respond to different distress demands in parallel, enhancing the diversity and coverage of signal transmission and ensuring the comprehensive expression of the user's distress intention.

[0091] Embodiment 2. The technical solution of this Embodiment 2 is different from that of Embodiment 1 in that it also discloses:

[0092] Step S3-1 includes:

[0093] S3-1-1. Obtain the preset deaf-mute level signal of the silent distress user; extract the deaf-mute level signal from the preset data of the silent distress user, and the deaf-mute level signal reflects the deaf-mute degree or impairment level of the silent distress user in terms of hearing and language.

[0094] S3-1-2. According to the preset deaf-mute level signal of the silent distress user, match the corresponding distress priority; the matching ensures that the urgency of the subsequent generated distress signal meets the deaf-mute level requirements of the silent distress user. For example, a silent distress user with a high-level deaf-mute signal will be given a higher distress priority. Of course, the matching relationship between the deaf-mute level signal and the distress priority can be a simple one-to-one mapping relationship, or it can be a weight calculation based on the different damage degrees of the hearing level and the language level to obtain a comprehensive index that can be one-to-one matched with the distress priority. That is, this distress priority is used for subsequent rescue resource allocation.

[0095] S3-1-3. According to the matched distress priority, generate and standardize and encapsulate it as a default distress signal; among them, the specific content of generating the default distress signal includes: extracting the emergency distress label, the distress priority identifier, and other distress signals in the aforementioned emergency distress event; and encapsulating the default distress signal is to perform data standardization encapsulation on the specific content of the generated default distress signal for subsequent packaging and transmission together with other distress signals.

[0096] In this embodiment, by obtaining the deaf - mute level signal of the silent - call - for - help user and generating a default distress signal with matching priorities, the system can flexibly allocate rescue resources according to different needs, significantly improving the rescue efficiency.

[0097] Step S3 - 2 includes:

[0098] S3 - 2 - 1: Enter the graphic - text call - for - help interface according to the called second matching instruction.

[0099] S3 - 2 - 2: In the graphic - text call - for - help interface, display several graphic - text call - for - help options through a distributed graphic - text window; the graphic - text call - for - help options include: common distress types and custom distress types; common distress types such as: medical emergency, fire, gas leakage, etc.; and the custom distress types can be factory - customized and selected according to the needs of the silent - call - for - help user.

[0100] S3 - 2 - 3: Select a certain graphic - text call - for - help option to determine the second distress signal; the silent - call - for - help user selects one or more graphic - text call - for - help options in the graphic - text call - for - help interface, records the selection of the silent - call - for - help user and determines it as the second distress signal, and the second distress signal represents the specific distress intention of the silent - call - for - help user.

[0101] S3 - 2 - 4: According to 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 set of various pre - set standardized packaged distress signals. The preset distress signals are defined according to common distress scenarios and needs, and a mapping relationship is established with the options in the graphic - text call - for - help interface (such as medical emergency, fire, gas leakage, etc.) so that the corresponding distress signal can be quickly matched after the user selects. Specifically:

[0103] Composition of the distress signal set: The distress signal set contains various different types of distress signals, and each signal represents a specific distress need. For example:

[0104] Medical emergency signal

[0105] Fire distress signal

[0106] Gas leakage distress signal

[0107] Alarm distress signal

[0108] Customized distress signal (can be customized according to user needs)

[0109] In this embodiment, through the graphic and text emergency call interface, common and customized emergency call options are displayed, enabling silent emergency call users to quickly select or define specific emergency call types, ensuring personalized transmission and rapid response of the emergency call signal.

[0110] Step S3-3 includes:

[0111] S3-3-1. Generate a location acquisition request according to the third matching instruction; the generation of the location acquisition request is to activate the positioning process and ensure that the system starts to collect the real-time location data of the silent emergency call user.

[0112] S3-3-2. Call the positioning module to obtain the real-time location of the current silent emergency call user according to the location acquisition request; wherein, the positioning module is pre-installed with GPS positioning, Wi-Fi positioning or cellular network-based positioning programs;

[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 geographical coordinates and the current timestamp from the real-time location to obtain the spatio-temporal signal of the silent emergency call user;

[0115] The geographical coordinates identify the location of the user, while the timestamp provides the specific time of location acquisition. These two pieces of information form the "spatio-temporal signal" of the user, ensuring that the location information has a clear identifier in both time and space.

[0116] S3-3-4. Generate and standardize and encapsulate into a location emergency call signal according to the spatio-temporal signal of the silent emergency call user;

[0117] Specifically: S3-3-3 can integrate the geographical coordinates and the timestamp into the location signal data packet using a unified data encapsulation format (such as JSON or Protobuf). Each field of the data packet is arranged in a standard format.

[0118] Furthermore, the steps for the signal encapsulation module to generate the emergency call data packet include:

[0119] S4-1. Collect the default emergency call signal, the user emergency call signal and the location emergency call signal;

[0120] Specifically, the system collects different types of generated emergency call signals from the execution results of the distributed matching requests. Specifically included are:

[0121] Default emergency call signal: An emergency call signal generated based on the preset deaf-mute level signal of the silent emergency call user, with corresponding emergency call tags.

[0122] User distress signal: A signal generated by the graphic distress option selected by a silent distress user on the graphic distress interface, representing its specific distress content.

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

[0124] The above signals 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, perform secondary standardization and encapsulation processing on the collected distress signals to ultimately ensure that the three different signals meet the transmission requirements in terms of format and data consistency. The secondary standardization and encapsulation processing includes:

[0127] Unify format: Standardize aspects such as the encoding, field length, and data type of each signal to ensure that all signals are consistent in structure.

[0128] Unify labels: Add formatted emergency labels, signal type identifiers, etc. to various signals so that the system can quickly identify the purpose and category of the signals.

[0129] Eliminate redundancy: Check whether there are redundant signals in the signal data to ensure that the data is concise and clear to improve transmission efficiency.

[0130] S4-3. Finally encapsulate the default distress signal, user distress signal, and location distress signal after secondary standardization and encapsulation processing to generate the distress data packet.

[0131] Specifically, the system finally encapsulates the distress signals after secondary standardization and encapsulation processing to generate a complete distress data packet. The specific process of the final encapsulation includes:

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

[0133] Add an emergency identifier: Add an emergency distress identifier to the data packet so that the rescue center can quickly identify and prioritize processing when receiving the data packet.

[0134] Generate the data packet structure: Pack and generate the distress data packet in a format that conforms to the communication protocol to ensure that there are no errors during transmission and unpacking.

[0135] In this embodiment, by collecting different distress signals, performing secondary standardized encapsulation processing, and finally encapsulating them, a unified distress data packet is generated, ensuring data consistency and security during the transmission process, and improving the accuracy and efficiency of rescue response.

[0136] In this embodiment, the graphic and text distress system can not only generate distress signals based on the user's own definition, but also combines preset default distress signals (such as emergency priorities) and location signals to form a distress data packet with multi-signal encapsulation. It can provide a more comprehensive and accurate distress signal than a single signal. Rescue personnel can quickly obtain the specific situation, emergency level, and location signal of the silent distress user from the distress signal and make a more efficient rescue response.

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