Description

Technical Field

[0001] The invention relates to the technical field of labor insurance shoes, and in particular to a pair of intelligent alarm AED labor insurance shoes and a working method thereof. Background Art

[0002] As protective equipment to ensure the safety of workers' feet, labor protection shoes play an indispensable role in labor protection. Traditional labor protection shoes currently on the market can effectively prevent operational risks such as punctures from sharp objects, crushing from heavy objects, electrical hazards and chemical corrosion, mainly through designs such as anti-puncture structures, impact-resistant toes, insulating materials and corrosion-resistant layers; for example, the patent with publication number CN118680358A provides a kind of puncture-proof labor protection shoes, which can have excellent anti-puncture capabilities by providing steel sheets, buffer springs, midsoles, etc. However, with the increasing complexity of modern industrial scenes and the continuous improvement of safety needs, the limitations of traditional labor protection shoes that can only provide simple physical protection are becoming increasingly prominent. Specifically: During the working process of the operators, sudden personal injury accidents or acute disease accidents may occur. Once these accidents occur, it is particularly important to promptly discover and treat the injured persons; especially for cardiac arrest, the most effective measure is to use AED equipment (automated external defibrillator) to perform electric defibrillation and cardiopulmonary resuscitation on the patient within the "golden 4 minutes" of the best rescue time. However, current AED devices face the following problems in practical applications: First, domestic AED devices are unevenly distributed, with the number per 100,000 people far below international standards, and the public lacks real-time perception of their locations, making it difficult for them to be quickly obtained in an emergency; second, professional AED devices have a complex structure and a certain operating threshold, and untrained users are prone to misoperation; third, in the existing technology, workers can monitor life safety signs by wearing safety bracelets, safety vests and other equipment, but the data links of these safety monitoring devices often stop at sending early warning signals, and cannot link emergency resources to achieve a closed-loop response mechanism with AED devices; at the same time, wearable safety monitoring devices also have limitations such as the need to be worn additionally, low alarm response efficiency, and easy damage when people fall to the ground.

[0003] Therefore, if the monitoring, alarm and AED functions can be integrated into the safety shoes, more effective countermeasures can be provided for emergencies during the working process. However, in the prior art, traditional safety shoes that can only provide simple physical protection cannot perform this function, so the present invention proposes an intelligent alarm AED safety shoe and a working method thereof. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent alarm AED safety shoe and a working method thereof to solve the following technical problems: the existing traditional safety shoes have limitations in practical applications, that is, they can only provide simple physical protection and cannot effectively respond to sudden personal injury accidents or acute disease accidents of workers during the work process.

[0005] The present invention is achieved by adopting the following technical solutions: A smart alarm AED safety shoe comprises a safety shoe body, the safety shoe body comprises a sole and an upper connected to the sole, a main control module, a monitoring module, an alarm prompt module and an AED module are arranged on the safety shoe body, the monitoring module, the alarm prompt module and the AED module are electrically connected to the main control module respectively; the main control module is used for overall management of the work of each module, the monitoring module is used for monitoring whether the wearer of the safety shoe is in a fallen state, the alarm prompt module is used for issuing alarm information and prompt information, and the AED module is used for performing electric shock defibrillation as needed; the main control module comprises a working switch, a battery and a main control chip, the monitoring module comprises a pressure sensor, the alarm prompt module comprises an alarm light and a horn, and the AED module comprises an electrode sheet and an AED control circuit.

[0006] The intelligent alarm AED safety shoes provided by the present invention can monitor the information related to the falling state of the wearer of the safety shoes by setting a monitoring module, and transmit the information to the main control module; then, the main control module will process and analyze the received information related to the falling state, and determine the falling state of the wearer of the safety shoes; if it is determined that the wearer of the safety shoes is in a falling state, the main control module will link the alarm prompt module to alarm; on this basis, an AED module is also set up, through which the core functions of the AED device (not all the functions of the complete AED device) can be realized, that is, electric shock defibrillation can be performed, and then timely rescue of patients with cardiac arrest can be carried out.

[0007] Furthermore, in the main control module, the working switch is arranged on the outer surface of the safety shoe body, the battery and the main control chip are arranged inside the safety shoe body; the battery is electrically connected to the main control chip and the charging port respectively, and the charging port is exposed from the outer surface of the safety shoe body. Among them, the charging port is exposed from the outer surface of the safety shoe body, which improves the convenience of charging, and the operator can easily find the location of the charging port without complicated operations.

[0008] Furthermore, in the monitoring module, the pressure sensor is arranged at the sole position inside the labor protection shoe body; the number of the pressure sensors is several, and the several pressure sensors are respectively distributed at the sole positions corresponding to the heel, forefoot, arch and toes. Among them, the sole pressure value obtained by the pressure sensor at the sole position can be used as information related to the falling state. If the operator falls, the pressure value will drop to a lower value. In addition, since the pressures borne by the heel, forefoot, arch and toes are different during the process of standing, walking and exercising, the pressure change patterns of various parts of the foot are different in different falling situations; therefore, the multi-dimensional pressure data collected by multiple pressure sensors can more accurately determine whether a person has fallen.

[0009] Furthermore, the monitoring module also includes a positioning chip, which is in communication connection with the main control chip, and the main control chip is in communication connection with the external monitoring terminal. By setting the positioning chip, the real-time location information of the operator can be obtained, and the main control chip transmits the real-time location information to the external monitoring terminal, so that the monitoring personnel and emergency rescue personnel (who can be professional rescue personnel or staff dispatched by the monitoring terminal, or the personnel around the fallen operator) can quickly obtain and reach the location of the operator.

[0010] Furthermore, in the AED module, the electrode sheet can be placed in an AED first aid bag that can be taken and placed. The AED first aid bag is arranged on the outer surface of the labor protection shoe body. An AED operation switch is arranged on or beside the AED first aid bag. The AED control circuit includes a heart rhythm acquisition circuit and an electric shock defibrillation circuit. The electrode sheet is electrically connected to the main control chip through the heart rhythm acquisition circuit and the electric shock defibrillation circuit. Among them, the working process of the AED module includes heart rhythm data acquisition, heart rate analysis and decision-making, and defibrillation implementation. Heart rhythm data acquisition is realized by the electrode sheet and heart rhythm acquisition circuit attached to a specific position of the chest of the fallen person. Heart rhythm analysis and decision-making are realized by the main control chip. Defibrillation implementation is realized by the main control chip, the electric shock defibrillation circuit, and the electrode sheet. In addition, the electrode sheet is placed in the AED first aid bag in a removable manner, so that the electrode sheet can follow the operator in real time, and can be quickly obtained in first aid situations; the AED operation switch is set to transmit the information that the emergency rescue personnel are in place to the main control chip, so that the main control chip can control the labor protection shoes from a simple fall alarm state to an AED processing state; in actual applications, the operation prompts of the AED operation switch can be printed on the outer surface of the AED first aid bag to remind emergency rescue personnel who have not touched this labor protection shoe to perform the correct operation.

[0011] Furthermore, the monitoring module also includes a gyroscope sensor, which is arranged inside the body of the safety shoe. The gyroscope sensor can monitor the angle changes of the safety shoe in all directions in real time. Once a fall occurs, the body posture will change instantly, and the angle of the shoe will also change sharply and greatly. The gyroscope sensor can quickly capture these angle change information and transmit it to the main control chip, which can then be verified with the data of the pressure sensor, thereby achieving a more accurate judgment effect.

[0012] Furthermore, the alarm prompt module also includes a manual alarm switch, which is arranged on the outer surface of the labor protection shoe body and is connected to the main control chip for communication. The manual alarm switch is provided to enrich the alarm implementation method, so that if the injured or sick operator does not fall to the ground, he can also autonomously alarm if he is conscious and has certain movement ability.

[0013] Furthermore, a heating module is also provided on the main body of the safety shoe, and the heating module includes a sole heating part and a foot surface heating part, and the sole heating part and the foot surface heating part are electrically connected to the main control module respectively. Among them, the setting of the heating module has many advantages, for example: first, when the operator works in a low temperature or humid working environment, the foot can be heated by the heating module, which helps to maintain the blood circulation of the foot, avoid the influence of the body on the work efficiency and body function due to the cold or dampness, and also improve the comfort and reduce the fatigue; second, when the injured or sick operator is waiting for rescue, if the ambient temperature is low, the foot can be heated by turning on the heating module, which helps to stabilize the core temperature of the body and relieve pain and discomfort. In addition, the heating module is divided into an independent sole heating part and a foot surface heating part, thereby realizing flexible control of the two heating positions, so that the heating at the corresponding position can be turned on according to the demand, and electric energy can be saved.

[0014] A working method of an intelligent alarm AED safety shoe, using the above-mentioned intelligent alarm AED safety shoe, comprises the following steps: Step 1: The working switch is turned on, the safety shoes enter the working state, and the monitoring module monitors in real time whether the wearer of the safety shoes is in a fallen state; Step 2: When the monitoring module detects that the wearer of the safety shoes has fallen, the main control chip links the alarm prompt module to sound an alarm; Step 3: With the cooperation of the main control chip, the alarm prompt module and the emergency rescue personnel, the AED module performs electric shock defibrillation on the wearer of the protective shoes who has fallen to the ground as needed.

[0015] Furthermore, the step 3 specifically includes the following sub-steps: Step 3-1: After the emergency rescue personnel arrive at the location of the wearer of the safety shoes, the main control chip controls the speaker in the alarm prompt module to play the AED usage step prompt tone; Step 3-2: The AED usage prompt tone guides the emergency rescue personnel to take out the electrode pads and stick them on the corresponding position of the wearer's body; Step 3-3: After the electrodes are in place, the heart rhythm signals are automatically collected and transmitted to the AED control circuit, and the AED control circuit processes the heart rhythm signals and transmits them to the main control chip; Step 3-4: The main control chip analyzes and determines whether electric shock defibrillation is required. If necessary, the main control chip sends a trigger instruction to the AED control circuit, thereby causing the electrode pads to output electric shock defibrillation current.

[0016] The beneficial effects achieved by the present invention are: Provided is an intelligent alarm AED labor protection shoe and a working method thereof. By setting a main control module, a monitoring module, an alarm prompt module and an AED module, and working steps based on these modules, the falling state of the wearer of the labor protection shoe can be monitored and an alarm can be automatically issued; on this basis, the carrying of AED electrodes can also be realized, and AED analysis and electric shock defibrillation can be quickly performed in emergency situations. Therefore, compared with the existing traditional labor protection shoes that can only provide simple physical protection, the present invention integrates monitoring, alarm and AED functions, and can provide more effective response measures for sudden accidents in the labor process.

[0024] The second aspect of this embodiment provides a working method of an intelligent alarm AED safety shoe. The intelligent alarm AED safety shoe described above is used. Please refer to Figure 7, including the following steps: Step 1: When the operator enters the work site and the work switch 8 is turned on, the safety shoes will enter the intelligent working state. Specifically: In the intelligent working state, the monitoring module will monitor in real time whether the wearer of the safety shoes is in a fallen state, that is, the pressure sensor 21 and the gyroscope sensor 18 will collect information related to the fallen state, and send the information related to the fallen state to the main control chip 17 for processing and analysis.

[0025] Step 2: When the wearer of the safety shoes falls to the ground, the monitoring module will detect the fall, and the main control chip 17 will link the alarm prompt module to alarm. Specifically: After the wearer of the safety shoes falls to the ground, the pressure sensor 21 will detect that the pressure value on the sole of the operator's foot drops below 1 bar, and the gyroscope sensor 18 will detect that the angle, angular velocity, acceleration and other data exceed the set relevant thresholds during the operator's fall. After the main control chip 17 receives the relevant data transmitted by the pressure sensor 21 and the gyroscope sensor 18 and processes and analyzes them, it will start the alarm light 4 and the speaker 5 to cooperate with the sound and light alarm, that is, the alarm light 4 flashes red and the speaker 5 emits a harsh beeping sound to remind other operators around the fallen operator to find them in time, so that they can try to take rescue measures as soon as possible. At the same time, the main control chip 17 will receive the positioning information transmitted by the positioning chip 19, and transmit the alarm information and positioning information to the external monitoring terminal; after the corresponding personnel responsible for the monitoring terminal receive the alarm information and positioning information, they can immediately notify the emergency rescue personnel to rush to the scene to carry out rescue operations, and can link the medical, fire and other emergency response systems according to the actual situation.

[0026] Step 3: With the cooperation of the main control chip 17, the alarm prompt module and the emergency rescue personnel, the AED module performs electric shock defibrillation on the wearer of the protective shoes who has fallen to the ground as needed. Specifically, it includes the following sub-steps: Step 3-1: After the emergency rescue personnel arrive at the position of the wearer of the safety shoes, the AED operation switch 2 is turned on under the action of the operation prompt on the surface of the AED first aid bag 3; after the main control chip 17 receives the signal that the AED operation switch 2 is turned on, the speaker 5 stops emitting the buzzing sound and switches to playing the AED usage step prompt sound.

[0027] Step 3-2: AED use steps prompt sound guides emergency rescue personnel to open the AED first aid bag 3, take out two electrodes, and stick the two electrodes on the right side of the sternum, below the clavicle and the outside of the left chest nipple and the mid-axillary line of the wearer of the labor protection shoe. Please refer to Figure 5 .

[0028] Step 3-3: After the electrode is in place, it will automatically collect the heart rhythm signal and transmit it to the AED control circuit, which will process the heart rhythm signal and transmit it to the main control chip 17. When the AED control circuit processes the heart rhythm signal, it first performs an amplification operation to enhance the signal strength to a level that is convenient for subsequent analysis; then performs filtering to remove noise and interference components in the signal, such as power frequency interference, myoelectric interference, etc., to obtain a pure and accurate heart rhythm signal; finally, the analog signal is converted into a digital signal to facilitate processing and analysis by the main control chip 17.

[0029] Step 3-4: After receiving the digital heart rhythm signal processed by the heart rhythm acquisition circuit 16, the main control chip 17 will perform a detailed analysis of the heart rhythm signal through the built-in algorithm to determine whether the heart rhythm of the wearer of the safety shoes is in an abnormal state requiring defibrillation, such as ventricular fibrillation, pulseless ventricular tachycardia, etc.

[0030] If the analysis result shows that the heart rhythm of the wearer of the safety shoes does not require defibrillation, the main control chip 17 will make the speaker 5 play the information that defibrillation is not required; if the analysis result shows that defibrillation is required, the main control chip 17 will make the speaker 5 play the information that defibrillation is required, and instruct the emergency rescue personnel to choose to turn on the AED discharge switch 9 to trigger defibrillation; after the AED discharge switch 9 is turned on, the main control chip 17 will send a trigger instruction to the defibrillation circuit 15 to make the electrode sheet output defibrillation current. Among them, when performing defibrillation, the main control chip 17 will continue to judge the state of the wearer of the safety shoes, and control the speaker 5 to continue to play the corresponding AED operation instructions or cardiopulmonary resuscitation instructions.

[0031] Step 4: The working switch 8 is turned off, and the safety shoes stop the intelligent working state.

[0032] In addition, in the above steps of this embodiment: When the safety shoes are in the intelligent working state, if the wearer of the safety shoes feels unwell but has not fainted or lost the ability to move, the alarm can be manually triggered by turning on the manual alarm switch 7.

[0033] When the safety shoes are in a non-intelligent working state, the wearer of the safety shoes can charge them through the charging port 11 and a suitable charging device. When the safety shoes are in an intelligent working state, if the power level of the battery 20 is lower than the power threshold required for AED defibrillation, the power indicator light 10 will flash green; if the power level of the battery 20 is lower than the power threshold required for intelligent monitoring and alarm, the power indicator light 10 will flash blue; the flashing of the power indicator light 10 can remind the wearer of the safety shoes to charge in time.

[0034] If the wearer of the safety shoes cannot or is inconvenient to use a special charging device to charge when charging is needed, for example, if the wearer has fallen to the ground, the safety shoes on both feet can be taken off, and then the discharge port 6 of the left safety shoe (the safety shoe only has a battery 20, a main control chip 17, a charging port 11 and a discharge port 6) is connected with the charging port 11 of the right safety shoe, so as to realize the charging of the right safety shoe by the left safety shoe; if the power of the left safety shoe is insufficient, the wearer can also take off the safety shoes of the companion (the left safety shoe is preferred), and operate in the same way as the connection method of the discharge port 6 and the charging port 11, please refer to Figure 6 , and then multiple labor protection shoes can be charged to the right labor protection shoe of the wearer of the labor protection shoe. This charging method can be used for emergency when the power is insufficient and it is impossible or inconvenient to use a special charging device, and it does not conflict with the first aid process, which can effectively increase the practicality of the intelligent alarm AED labor protection shoe.

[0035] To sum up, the intelligent alarm AED labor protection shoes and the working method thereof provided in this embodiment, by setting the main control module, the monitoring module, the alarm prompt module and the AED module, as well as the working steps based on these modules, can monitor the falling state of the wearer of the labor protection shoes and automatically alarm; on this basis, it is also possible to carry AED electrodes, and quickly perform AED analysis and electric shock defibrillation in emergency situations; therefore, the integration of monitoring, alarm and AED functions can provide more effective response measures for sudden accidents during the labor process.

[0036] Example 2 This embodiment provides an intelligent alarm AED labor protection shoe, which is further provided with a heating module on the basis of Embodiment 1, specifically: Please refer to Figure 8 The heating module includes a sole heating part and a foot surface heating part, which are electrically connected to the control module (the battery 20 and the main control chip 17), respectively, and the main control chip 17 is integrated with the heating control module. The sole heating part includes a heating film 23 and a sole heating switch, the heating film 23 is laid on the inner side of the sole, and the sole heating switch (not shown in the figure) is arranged on the outer side of the upper; the instep heating part includes a heating plate 22 and a foot surface heating switch, the heating plate 22 is embedded in the part of the inner side of the upper corresponding to the instep, and the instep heating switch (not shown in the figure) is arranged on the outer side of the upper.

[0037] In this embodiment, the heating film 23 adopts a flexible graphene heating film, which has the advantages of high heating efficiency and good flexibility; the heating plate 22 adopts a resistance wire heating plate distributed in a grid shape, which can ensure uniform heating and reduce the impact on foot activities. Temperature sensors are also integrated on the heating film 23 and the heating plate 22, respectively, and the temperature sensors are connected to the main control chip 17 for real-time monitoring of the heating temperature.

[0038] Based on the above structure, when using the safety shoes: when the operator is working in a low temperature or humid working environment, the heating module can be used to heat the feet, which helps maintain blood circulation in the feet and avoids the effects of cold or dampness on work efficiency and body functions. It can also improve comfort and reduce fatigue. In addition, if the injured or sick operator is waiting for rescue in a low ambient temperature, the heating module can be turned on to heat the feet, which helps stabilize the core body temperature and relieve pain and discomfort. Among them, when the heating temperature reaches the set maximum temperature or an abnormal temperature rise occurs, the temperature sensor will feed back a signal to the main control chip 17, and the main control chip 17 will immediately cut off the power supply to prevent overheating and scalding the feet, thereby ensuring safety in use.

[0039] It should be noted that other parts of the above scheme that are not described in detail or expanded, such as the software technology of the main control chip 17 to implement various controls, the specific shape and size of each installation space, the specific structure of the dust cover, the specific selection of each switch, etc., are all prior art or conventional designs in the field, and do not belong to the improvements made by the present invention on the prior art, nor do they belong to the protection scope of the technical solution of the present invention, so they will not be repeated in this article. Of course, the above content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of the embodiments of the present invention; the present invention is not limited to the above examples, and the equal changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent coverage of the present invention.
