Description

Technical Field

[0001] The present invention relates to a protection system and method, and in particular to an intelligent epidemic prevention monitoring and response system and a monitoring and response method thereof. Background Art

[0002] With the development of the economy and society, safety and health are receiving more and more attention. As an important part of personal protective equipment, protective clothing has received widespread attention due to its wide range of applications. my country is a major consumer of clothing products. In recent years, with the continuous increase in the country's investment in production safety and the support of relevant policies, the protective clothing industry has shown a booming development trend. At the same time, as the hazards present new characteristics and new requirements for the working environment and personnel are put forward, the technology related to protective clothing is also constantly being improved.

[0003] In practice, relying solely on a single protective clothing is often not enough to effectively prevent harmful factors in the environment from harming workers. Protective clothing should form a protection system with functions such as head protection, eye protection and threat factor alarm to provide comprehensive protection for workers. Therefore, a systematic design of protective clothing is required, which is also the main shortcoming of the current protective clothing industry.

[0004] In the face of the epidemic, due to the lack of in-depth understanding of the virus in the early stages of the epidemic, it is necessary not only to provide adequate protection for medical staff and related anti-epidemic personnel, but also to monitor the various vital signs and parameters of these personnel in real time in order to fully understand their health status, prevent large-scale transmission among medical staff and anti-epidemic personnel, and avoid weakening the backbone of the anti-epidemic front.

[0005] At the same time, once a medical staff member is found to be in an abnormal health condition or even suffers from a disease, there are two major problems that need to be solved urgently. On the one hand, how to determine the path with the shortest time or the least number of people, so that the sick person can enter a specific isolation area as soon as possible or other medical staff can come to take necessary measures as soon as possible, but no protection system has been found to focus on solving this problem. On the other hand, timely grasping the movement trajectory and contact history of the person is crucial to the effective prevention and control of the epidemic, but currently the relevant information is mainly reported manually, which not only has high labor costs and poor real-time performance, but also has low reliability and accuracy of location information, making it difficult to effectively monitor the spread of the disease. Especially in places with large traffic, due to the massive growth of video data, the practice of manually counting movement trajectories becomes increasingly stretched, time-consuming and laborious. If video surveillance is used, when there are many monitoring nodes, there may be a camera failure, power outage or video data tampering by hackers at a certain node, which makes it difficult to form a closed loop of movement trajectory monitoring, and still cannot be separated from the manual statistics and reporting methods.

[0006] In addition, under normal circumstances, the human body loses 2 to 5 kg of water every day, most of which is through sweat. However, due to the poor heat dissipation of protective clothing, medical staff often sweat profusely and become exhausted after working for a long time, leading to problems such as difficulty breathing, severe dehydration, and skin damage, causing great inconvenience to their rescue work.

[0007] Therefore, in response to the above problems, there is an urgent need to develop an intelligent epidemic prevention system and method that can not only achieve excellent protection, but also conduct real-time monitoring and rapid response, and integrate protective equipment with a monitoring and response platform. Summary of the invention

[0008] The purpose of the present invention is to overcome the defects in the prior art and provide an intelligent epidemic prevention system with excellent protection performance, anti-tampering monitoring function and rapid response function, as well as a monitoring and response method using the intelligent epidemic prevention system.

[0009] To achieve the above-mentioned purpose, the present invention provides an intelligent epidemic prevention monitoring and response system, which includes intelligent protective clothing, a plurality of video monitoring nodes and a monitoring management platform. The system may include more than two video monitoring nodes.

[0010] The intelligent protective clothing includes a protective cap 1, a protective suit 2 and protective pants 3. The protective cap 1 is provided with a transparent eye protection sheet 4. The intelligent protective clothing also includes a body temperature monitoring module, an alarm module, a distance monitoring module, a positioning module and a wireless communication module. The body temperature monitoring module, the alarm module, the distance monitoring module and the positioning module are electrically connected to the wireless communication module respectively, and the wireless communication module is connected to the monitoring management platform. The body temperature monitoring module includes a temperature sensor arranged on the inner side of the protective cap 1.

[0011] The temperature sensor is arranged inside the protective cap 1 to make the temperature measurement data more accurate, and it can be preferably arranged inside the protective cap 1 near the user's forehead. The body temperature monitoring module sends the temperature data collected by the temperature sensor to the monitoring and management platform through the wireless communication module, thereby monitoring the body temperature of the protective clothing user so as to take prevention and control measures in time. The transparent eye protection sheet 4 can be set to be detachable. After the monitoring and management platform receives the body temperature information of the protective clothing user, if the body temperature information meets the temperature preset condition, such as the body temperature exceeds the preset temperature threshold, or several body temperature data within a certain period of time are higher than the preset temperature threshold, or other preset conditions, the monitoring and management platform sends an alarm instruction to the alarm module through the wireless communication module to remind the protective clothing user and the surrounding personnel to take prevention and control measures in time. The distance monitoring module can obtain the distance information between the protective clothing user and the surrounding personnel, and send it to the monitoring and management platform through the wireless communication module. If the distance information meets the distance preset condition, such as the distance is less than the preset distance threshold or other preset conditions, the monitoring and management platform sends an alarm instruction to the alarm module through the wireless communication module to remind the protective clothing user and the surrounding personnel to pay attention to adjusting the protection distance. The positioning module is used to obtain the position coordinates of the protective clothing user, and can upload them to the monitoring management platform through the wireless communication module. The three-dimensional coordinate system used by the position coordinates can include a plane coordinate system and an elevation system. The plane coordinate system can be an independent coordinate system, a relative coordinate system or an absolute coordinate system, and the elevation system can be the 1956 Yellow Sea elevation system, the 1985 national elevation benchmark, an independent elevation system or a relative elevation system. The three-dimensional coordinate system is composed of the selected plane coordinate system and elevation system.

[0012] The video surveillance nodes are connected to each other in communication to form a blockchain network, and are all connected to the monitoring and management platform in communication. The video surveillance node includes a video surveillance module, a blockchain encryption module, a distributed storage module and a perception prompt module. The video surveillance module includes a camera, a video memory and a video processor connected in sequence, the video memory is used to store video data, and the video processor extracts the required video data from the video memory according to the instructions of the monitoring and management platform and transmits it to the monitoring and management platform. The blockchain encryption module is used to encrypt the video data in the video memory with an encryption algorithm to generate a blockchain key and upload it to the blockchain network, the distributed storage module is used to download and store the blockchain keys of all video surveillance nodes from the blockchain network, and the perception prompt module is used to perceive the changes of the blockchain keys in the distributed storage module and send prompt information to the monitoring and management platform. If the video data of any video surveillance node is damaged or tampered with due to a fault, the corresponding blockchain key generated by the blockchain encryption module will change, and the perception prompt modules of other video surveillance nodes will perceive the change and send prompt information to the monitoring and management platform.

[0013] The monitoring and management platform includes a BIM modeling module, a BIM position determination module and a BIM route planning module. The BIM modeling module is used to establish a three-dimensional BIM model, and the BIM position determination module is used to input the position coordinates uploaded by the positioning module into the three-dimensional BIM model and transmit the BIM position information to the BIM route planning module. The BIM route planning module is used to calculate the optimal route between the position and the preset position according to the BIM position information. The BIM modeling module can first establish a three-dimensional coordinate system, establish a three-dimensional model based on this, and then establish a three-dimensional BIM model according to the building construction drawing, the structural construction drawing, the equipment construction drawing and the actual information on the site. A three-dimensional laser scanner can also be used to obtain the three-dimensional coordinate data on the site, collect spatial point information, and quickly establish a three-dimensional BIM model on the site. The three-dimensional laser scanner is, for example, a Trimble TX8 three-dimensional scanner. The BIM position determination module can accurately locate the position information of the relevant personnel in the three-dimensional BIM model, and can intuitively display the surrounding environment of the personnel. The BIM route planning module calculates and plans the optimal path between the two positions based on the BIM position information and the path information and building information between the position and the preset position, and is sent by the monitoring and management platform to the protective clothing user or relevant medical staff. The monitoring management platform can also extract video data from video monitoring nodes in real time and use the number of people passing through as one of the parameters for calculating the optimal path. The preset location can be in the isolation area, isolation room or other locations set for epidemic prevention purposes.

[0014] According to the intelligent epidemic prevention monitoring and response system of the present invention, the optimal route is the route with the shortest distance, the shortest time or the least number of people in the route. The algorithm used by the BIM route planning module to calculate the optimal route is a meta-heuristic algorithm, a Dijkstra algorithm, a Bellman-Ford algorithm, a Floyd-Warshall algorithm or a Johnson algorithm. The meta-heuristic algorithm is an improvement on the heuristic algorithm, and is the product of the combination of a random algorithm and a local search algorithm, including a taboo search algorithm, a simulated annealing algorithm, a genetic algorithm, an ant colony optimization algorithm, a particle swarm optimization algorithm, an artificial fish swarm algorithm, an artificial bee colony algorithm, an artificial neural network algorithm, and the like. The Dijkstra algorithm, also known as the Dijkstra algorithm, is an algorithm for the shortest path from one vertex to the remaining vertices, and solves the shortest path problem in a weighted graph. The Bellman-Ford algorithm, also known as the Bellman-Ford algorithm, is an algorithm for solving the single-source shortest path problem, created by Richard Bellman and Lester Ford. The Floyd-Warshall algorithm, referred to as the Floyd algorithm, is an algorithm that uses the idea of ​​dynamic programming to find the shortest path between multiple source points in a given weighted graph. Johnson's algorithm is an algorithm for finding the shortest paths between all pairs of points in a network with no negative cycles and negative weights.

[0015] According to the epidemic prevention intelligent monitoring and response system of the present invention, the intelligent protective clothing also includes a fresh air module, and the fresh air module includes an air intake filter unit, a fan unit and an air guide unit.

In order to achieve a better filtering effect, the filter layer is usually located in the air intake compartment and close to the air intake housing, preferably close to the air intake hole of the air intake housing. There may be multiple air ducts, or the air ducts may have multiple air outlet ends, so that the air outlet ends of the air ducts are distributed at multiple locations in the smart protective clothing to provide fresh air for multiple parts of the user.

Preferably, heat sinks can be arranged on both sides of the semiconductor refrigeration sheet. The semiconductor refrigeration sheet can be arranged substantially vertically with the partition, and can preferably be arranged in the middle position of the air outlet compartment, so that the size of the refrigeration chamber and the heating chamber are substantially the same. If the temperature is high or the room is hot and stuffy, the cold air port can be connected to the air duct, and the hot air port can be vented to make the user feel cool and comfortable. However, if the indoor temperature is low or working in a cold outdoor environment, the hot air port can be connected to the air duct, and the cold air port can be vented to make the user feel warm.

[0017] The fresh air module also includes a wind control unit, which includes a controller and an air pressure sensor. The air pressure sensor is arranged in the intelligent protective clothing, and the controller adjusts the speed of the fan according to the air pressure data of the air pressure sensor. The fan is a micro DC fan with a rated voltage of 3 to 5V. The filter layer includes a HEPA filter layer. The fresh air module is electrically connected to the wireless communication module.

The controller adjusts the wind speed according to the air pressure data so that the fresh air module forms a stable flow field inside the protective clothing and keeps the internal air pressure at a comfortable level for the human body, such as +20Pa to +120Pa. In addition, the air pressure data of the air pressure sensor can be transmitted to the monitoring management platform through the wireless communication module, which can be used to monitor whether the protective clothing is damaged. If it is damaged, the fresh air module increases the fan speed to adjust the internal air pressure of the protective clothing, and can send an alarm prompt information to the user and surrounding personnel through the alarm module. The HEPA filter layer can be H12 grade or N95 grade, or higher. The controller can also be connected to a manual switch or knob, allowing the user to switch or adjust the wind speed as needed.

[0019] The wireless communication module includes a wireless processor, a radio frequency transceiver and a built-in antenna, and communicates with the monitoring management platform through a base station. The distance monitoring module is electrically connected to the alarm module. The base station can be a GPRS base station, a GSM base station, a WIFI base station, a 4G base station or a 5G base station. When the distance between the user of the smart protective clothing and the surrounding personnel is less than a preset distance threshold, the distance monitoring module can directly send an alarm instruction to the alarm module to remind them to keep the distance.

[0020] The intelligent protective clothing also includes a power supply module, which includes a power management chip, a charging management chip, a wireless charging coil and a lithium battery. The power supply module is electrically connected to the body temperature monitoring module, the wireless communication module, the alarm module, the distance monitoring module, the fresh air module and the positioning module respectively.

The power supply module can provide the required power to the components such as the body temperature monitoring module of the present invention. The power supply module includes a wireless charging coil, etc., which can be wirelessly charged, which helps to enhance the waterproof performance of the entire circuit. Since the power supply module is connected to the wireless communication module and the alarm module, the power data can be sent to the monitoring and management platform through the wireless communication module. If the remaining power of the power supply module meets the preset conditions, such as being lower than the preset power threshold, or other preset conditions, the monitoring and management platform sends an alarm instruction to the alarm module through the wireless communication module to prompt the user to charge in time; or, when the remaining power is low, the power supply module can also directly send an alarm instruction to the alarm module to prompt the user. The alarm module can use different beeps, different LED light colors or different patterns of LED lights to indicate different alarm prompts, including abnormal body temperature prompts, too close distance prompts, low battery prompts, etc., or use a flexible LED display to display richer and more intuitive information to facilitate identification by protective clothing users and surrounding personnel.

[0021] According to the intelligent monitoring and response system for epidemic prevention of the present invention, the video monitoring module also includes a pan-tilt and a protective cover, and the camera is arranged in the protective cover and mounted on the pan-tilt. The camera is a wireless infrared high-definition camera. The video storage device regularly cleans up video data whose storage time exceeds the set time.

[0022] The monitoring and management platform also includes a face database and a video processing module. The face database is used to store identity information and corresponding face images and face features. The video processing module is used to extract the face image to be identified from the video data and analyze the face features to be identified, and compare and identify the face features to be identified with the face features in the face database. The comparison and identification can be a similarity match. For example, if the similarity match value is equal to or higher than a preset value, the comparison result is saved to the monitoring and management platform, and the monitoring and management platform monitors and records the activity trajectory and time of the person. If the similarity match value is lower than the preset value, it is deemed that the information in the face database is not matched, and the face features of the person are stored in the face database and marked as an outsider, and the relevant information of the person is subsequently entered, or the monitoring and management platform sends a warning message to the relevant staff.

[0023] According to the intelligent monitoring and response system for epidemic prevention of the present invention, the material of the protective cap 1, protective clothing 2, and protective pants 3 is a composite polyester fabric, and the composite polyester fabric includes a surface layer, an intermediate layer, and an inner layer. The surface layer is a polyester fabric layer, the intermediate layer is a polyvinylidene chloride film layer, and the inner layer is a non-woven fabric layer. At present, most protective clothing is disposable, and the materials are mainly spunbond nonwoven fabrics, spunbond fabric coatings, airtight films, SMS nonwoven fabrics, spunlace fabrics, etc., with low moisture permeability, poor wearing comfort, limited virus penetration resistance, and not conducive to long-term wear by medical staff. In addition, disposable protective clothing greatly increases the cost of medical waste treatment and aggravates environmental pressure. The polyester used in the surface layer has good waterproof, dustproof, acid and alkali resistance and other properties, can physically isolate pathogens and other toxic and harmful chemicals, has dual functions of biological and chemical defense, good heat resistance, can be sterilized and disinfected at high temperature and high pressure, can be used repeatedly, and reduce the amount of medical waste. The middle layer is a polyvinylidene chloride film layer, which has good moisture permeability, is comfortable to wear, can block blood, bacteria and viruses, and has high chemical stability, is resistant to corrosion by strong acids and alkalis and other chemical agents, is resistant to high temperatures, and can be reused after high-temperature disinfection.

[0024] The transparent goggle sheet 4 includes a first wear-resistant layer 41, a first anti-fog layer 42, a substrate layer 43, a polarizing layer 44, a second anti-fog layer 45 and a second wear-resistant layer 46, which are arranged in sequence from the inside to the outside. The first wear-resistant layer 41 and the second wear-resistant layer 46 are silicon oxide layers, the first anti-fog layer 42 and the second anti-fog layer 45 are hydrophilic acrylic resin layers, and the substrate layer 43 is a transparent resin. Silicon oxide generally refers to silicon dioxide, which is used to prevent friction damage to the lens, increase the wear resistance and hardness of the lens, extend the service life, and reduce the cost of use. The first anti-fog layer 42 and the second anti-fog layer 45 are made of hydrophilic acrylic resin, which has strong hydrophilicity, reduces the reflection and refraction caused by water mist, and achieves an anti-fog effect. The polarizing layer 44 can filter the reflected light by using the principle of light polarization, increase the imaging contrast, and effectively reduce or eliminate the reflection of non-metallic surfaces, which is conducive to dispersing the stimulation of strong light, so that the eyes can have a clear field of vision under strong light and keep the eyes comfortable.

[0025] According to the intelligent monitoring and response system for epidemic prevention of the present invention, the thickness of the polyester fabric layer is 0.6-1.0 mm, the thickness of the polyvinylidene chloride film layer is 0.1-1.0 mm, and the non-woven fabric layer contains nano silver, nano titanium dioxide or nano bismuth tungstate. The surface layer, the middle layer and the inner layer are all filled with moisture-curing reactive polyurethane hot melt adhesive. Nano titanium dioxide and nano bismuth tungstate can generate free radicals under light, and redox reactions will occur when they come into contact with viruses and bacteria, which can kill viruses and bacteria and decompose them. Moisture-curing reactive polyurethane hot melt adhesive has excellent bonding strength, chemical corrosion resistance and aging resistance, and stable performance. Not only can the surface layer, the middle layer and the inner layer of the present invention be compounded into a composite polyester fabric, but also the adhesive film formed has good air permeability and moisture permeability, which can effectively block organic matter, bacteria and viruses.

[0026] According to the intelligent epidemic prevention monitoring and response system of the present invention, the protective cap 1, protective clothing 2 and protective pants 3 are integrated, a sealing zipper 5 is provided at the middle position of the front of the protective clothing 2 and extends to the top of the protective cap 1, and the transparent eye protection piece 4 is provided on both sides of the opening of the protective cap 1, and a filter 6 is also provided below the transparent eye protection piece 4. The integrated intelligent protective clothing can better isolate harmful substances such as bacteria and viruses. Using this structure, the zipper can be pulled from the lower end of the protective clothing 2 to the top of the protective cap 1, so that the protective clothing 2 and the protective cap 1 are conveniently closed. The transparent eye protection piece 4 can be set at appropriate positions on both sides of the opening of the protective cap 1 according to ergonomics to facilitate the user to observe the outside world. The filter 6 can also be set at an appropriate position of the user's mouth, mainly used to filter the air for breathing. The transparent eye protection piece 4 and the filter 6 can be detachably set on the protective cap 1, for example, using Velcro, sealing strips, etc., for easy cleaning and replacement.

[0027] According to the intelligent epidemic prevention monitoring and response system of the present invention, the opening of the protective cap 1, the cuffs of the protective clothing 2, and the trouser legs of the protective pants 3 are all provided with elastic bands and adjustable length Velcro bands. The protective clothing 2 is provided with several Velcro sticking areas. The protective clothing 2 or the protective pants 3 is provided with a tool bag or a pen bag. The outer surface of at least one of the protective cap 1, the protective clothing 2, and the protective pants 3 is provided with a reflective strip. The temperature sensor is a platinum resistance temperature sensor. The filter sheet 6 includes one or more of a non-woven fabric layer, a cotton layer, an activated carbon filter layer, and a melt-blown polypropylene fiber layer. The sealing zipper 5 is a TPU airtight zipper. The filter layer also includes an activated carbon filter layer and a photocatalyst filter layer. The elastic band and Velcro band can adjust the opening size more freely, and adopt an elastic design, which is comfortable and free to wear. The Velcro sticking area can be a Velcro hook surface or a Velcro fur surface, and the name, department, unit, and other related information of the protective clothing user can be printed or handwritten on the Velcro for easy identification. The tool bag or pencil case is convenient for users to carry related tools. For example, the pencil case can be set on the outside of the sleeve of the protective clothing 2, and the tool bag can be set on the protective clothing 2 and the protective pants 3 to reduce the time spent by medical staff to go back and forth to the nurse's station to get items. The reflective strip is a safety device that mainly reflects the surrounding light at night to serve as a warning. The platinum resistance temperature sensor has good accuracy and stability due to the stable characteristics of platinum. It will not cause physical or chemical changes due to high and low temperatures. For example, a thin film platinum resistance temperature sensor can be selected. The photocatalyst filter layer can include nylon cloth and nano-scale titanium dioxide particles coated on the nylon cloth, or coated with other photocatalysts.

[0028] The temperature monitoring module, alarm module, distance monitoring module, wireless communication module, power supply module, fresh air module, positioning module, etc. of the present invention can be set to be separable or detachable from the protective clothing. When the protective clothing needs high-temperature sterilization and disinfection, these modules can be removed to prevent high temperature from damaging electronic components, or, when the protective clothing is damaged or reaches the end of its service life, these modules can also be removed and reused in other protective clothing. Preferably, the video monitoring node can be detachably arranged on the intelligent protective clothing, such as the top of the protective cap 1, to obtain a better field of view. The video monitoring node can be electrically connected to the power supply module.

[0029] The present invention also provides an intelligent monitoring and response method for epidemic prevention, which uses the intelligent monitoring and response system for epidemic prevention of the present invention and may include the following steps:

[0030] (A) The BIM modeling module establishes a three-dimensional BIM model.

[0031] (B) The monitoring management platform monitors whether the body temperature of the user of the smart protective clothing meets the preset temperature conditions based on the temperature data uploaded by the body temperature monitoring module. If so, it proceeds to step (C). If not, it continues to monitor the body temperature of the user of the smart protective clothing.

[0032] (C) The monitoring management platform sends an alarm command to the alarm module. The BIM position determination module determines the BIM position information of the user of the smart protective clothing in the three-dimensional BIM model according to the position coordinates uploaded by the positioning module.

[0033] (D) The BIM route planning module calculates the optimal route between the user's location and the preset location based on the BIM location information of the user of the smart protective clothing.

[0034] Step (A) may include: the BIM modeling module first establishes a three-dimensional coordinate system, establishes a three-dimensional model based on the system, and then establishes a three-dimensional BIM model based on drawings or on-site information. Alternatively, a three-dimensional laser scanner is used to obtain on-site three-dimensional coordinate data to establish a three-dimensional BIM model.

[0035] Step (C) may include: the monitoring management platform monitors whether the distance between the user of the smart protective clothing and surrounding personnel meets the preset distance conditions based on the distance information uploaded by the distance monitoring module, and if so, sends an alarm instruction to the alarm module.

[0036] Step (D) may include: the monitoring management platform sends the optimal route to the user of the smart protective clothing or relevant medical staff.

[0037] The method of the present invention may further include step (E): the monitoring management platform forms the movement trajectory of the user of the smart protective clothing according to the position coordinates uploaded by the positioning module within a specific time period. It may also include step (F): the monitoring management platform forms the movement trajectory of the people around the user of the smart protective clothing according to the video data of the video monitoring node using the video processing module and the face database. In this way, detailed information on the movement trajectory and contact history of the relevant personnel can be obtained.

[0038] Based on the above technical solution, the epidemic prevention intelligent monitoring and response system and method of the present invention have but are not limited to the following beneficial effects:

[0039] 1. The epidemic prevention intelligent monitoring and response system of the present invention has both protection function and monitoring function. On the one hand, multiple video monitoring nodes can comprehensively and effectively collect video data, combined with the face recognition function of the monitoring management platform, suitable for tracking the movement trajectory of people who are not wearing protective clothing; on the other hand, the positioning module of the protective clothing can upload the position coordinates of the user of the protective clothing in real time, thereby also tracking its movement trajectory. The combination of the two can obtain the movement trajectory and contact history of all relevant personnel, which is very important for epidemic prevention and control. At the same time, by adopting blockchain technology, each video monitoring node can achieve the effect of monitoring data tampering with each other without the need for a central node, and then send relevant prompt information to the monitoring management platform, so as to respond quickly to equipment failures, hacker attacks, etc., which reduces the security management cost of video data, improves the credibility and availability of video data, and can automatically form the movement trajectory information of relevant personnel, which helps to greatly reduce the manual workload.

[0040] 2. The system of the present invention also has a rapid response function. If the system monitors that the health status of the user of the protective clothing is abnormal, or the user of the protective clothing finds that people around him have suspected symptoms, etc., and needs to be transferred to the isolation area or call other medical staff to take necessary measures, the system can use the BIM modeling module, BIM location determination module and BIM route planning module to provide the optimal route between the current location and the isolation area, such as the shortest distance, shortest time or the least number of people in the route, so that the purpose of prevention and control can be achieved quickly and safely.

[0041] 3. Compared with the existing protective clothing, the intelligent protective clothing in the present invention includes a body temperature monitoring module, an alarm module, a distance monitoring module, a wireless communication module, a fresh air module, a positioning module, a power supply module, etc. The body temperature of the user can be monitored in real time through the body temperature monitoring module, and the distance between the user and others can be monitored in real time through the distance monitoring module. The body temperature and distance information can be transmitted to the monitoring and management platform through the wireless communication module. Once the monitoring and management platform detects that the body temperature or distance meets the preset conditions, it sends instructions to the alarm module through the wireless communication module, such as visual alarms or sound alarms, etc., to remind the user and surrounding personnel to pay attention to protection. The fresh air module provides the user with safe, clean and temperature-appropriate fresh air, which greatly improves the physical comfort of the protective clothing. The positioning module reports the user's position coordinates to the monitoring and management platform. The power supply module provides the necessary electrical energy for the normal operation of the above modules to avoid the restriction of the power cord on the user's range of motion. Therefore, the intelligent protective clothing is comprehensive in function, reasonable in design, and comfortable to wear.

[0042] 4. The intelligent protective clothing of the present invention has a fresh air module, which uses a filter layer to introduce clean and safe air. The fan unit and the air guide unit accelerate the air flow in the protective clothing. The wind control unit automatically adjusts the air pressure of the protective clothing to a suitable level. The temperature variable unit provides cold air or hot air to adapt to the temperature of the working environment, thereby effectively alleviating the user's feeling of stuffiness as a whole and making the body feel more comfortable, thereby expanding the scope of use scenarios of the intelligent protective clothing in high or low temperature environments.

[0043] 5. The intelligent protective clothing of the present invention adopts composite polyester fabric, which includes a multi-layer structure of polyester, polyvinylidene chloride film and non-woven fabric, etc. It has good physical isolation performance and air permeability and moisture permeability, is safe and comfortable, and has good heat resistance.

In a preferred embodiment, the video memory can regularly clean up video data whose storage time exceeds the set time to save storage space.

[0067] The blockchain encryption module is used to encrypt the video data in the video storage with an encryption algorithm to generate a blockchain key and upload it to the blockchain network. The encryption algorithm can be a hash encryption algorithm or an asymmetric encryption algorithm. The distributed storage module is used to download and store the blockchain keys of all video surveillance nodes from the blockchain network. The perception prompt module is used to perceive the modification of the blockchain key in the distributed storage module and send a prompt message to the monitoring management platform. If the video data is damaged or tampered with, the corresponding blockchain key generated by the blockchain encryption module will change. After the perception prompt module perceives the change, it will send a prompt message to the monitoring management platform, so that it can respond quickly to related equipment failures or hacker attacks.
