2. US20210248505A1 This patent provides a system which includes an article of personal protective equipment (PPE) comprising one or more sensors, the one or more sensors configured to generate usage data that is indicative of an operation of the article of PPE; and at least one computing device comprising a memory and one or more computer processors that: receive the usage data that is indicative of the operation of the article of PPE; apply the usage data to a safety learning model that predicts a likelihood of an occurrence of a safety event. Instead of providing an article of Personal Protective Equipment (PPE) with sensors, the present disclosure provides an edge device trained with machine learning and fitted at suitable locations to cover the entire construction area and a computing unit to monitor proper use of personal protective equipment by the workers in the construction site and generate alert on flouting the safety norms.
3. US6381482B1 This patent presents a fabric including a flexible information infrastructure integrated within the fabric for collecting, processing, transmitting and receiving information. The fabric can be provided with sensors for monitoring body Vital Signs, Such as heart rate, EKG, pulse, respiration rate, temperature, voice, and allergic reaction, as well as penetration of the fabric. This disclosure instead of monitoring the body vital signs, provides a system for monitoring proper use of personal protective equipment or safety wearables by the workers in the construction sites and hence helping in protecting the workers from any mishaps.
4. US20090040014A1 This patent provides a system for monitoring the proper use of personal protective equipment used by persons in a potentially hazardous work site. The system includes a sensor tag coupled to at least one item of the personal protective equipment and a detector configured to communicate with the sensor tag. A processor based device is configured to determine, based upon a detected characteristic of the sensor tag, whether the personal protective equipment is sufficient to commence work at the work site. The sensors coupled to the personal protective equipment are prone to damage in case of extreme events and hence the present disclosure presents a system for monitoring the proper use of personal protective equipment with the help of an edge device fitted at suitable locations with unobstructed view and a monitoring unit to monitor proper use of the safety wearables.
5. US20170245806A1 The current patent provides methods and systems for monitoring workplace safety and evaluating risks. The method comprises of receiving signals from at least one wearable device, identifying portions of the signals corresponding to physical activities, excerpting the portions of the signals corresponding to the physical activities, and calculating risk metrics based on measurements extracted from the excerpted portions of the signals, the risk metric indicative of high risk lifting activities. The present disclosure, instead of calculating risk metrics based on measurements extracted from the excerpted portions of the signals received from the wearable device, the present disclosure uses an edge device and a monitoring unit to make sure that the workers are wearing the personal protective equipment required to work at the site.
6. US10542332B2 This patent provides a system which includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.

Construction industry is the backbone of development of every country in the world. The physical and working conditions in the construction industry is the most risky and hazardous. The workers are exposed to extreme conditions like dust, heat, cold etc. and to dangerous conditions as well posed by construction equipment, tools and machinery thus making it mandatory for the workers to wear the safety wearables commonly known as personal protective equipment. Due to the lack of monitoring in large construction sites, the workers fail to abide by the safety rules and wear safety wearables thus inviting fatal injuries and risking the lives of the workers.
In order to monitor and ensure the safety of workers at the construction sites by making sure the proper use of the personal protective equipment by the workers, the present invention provides a system comprising of a network of connected edge devices installed at suitable places with unobstructed view to continuously monitor and alarm the monitoring unit in case of any non-compliance of the use of safety wearables by the workers. The real-time monitoring system comprise of an edge device to analyze and determine whether any personal protective equipment is worn by any worker or not. The edge device consists of a camera (100) for constantly monitoring the workers, a computing unit (101), an alert system (102); consisting of hooter and red LEDs; for generating the alert and warning the concerned worker to follow safety norms by wearing the safety wearables and a RF modem (102) to send the data to the monitoring unit to take suitable action. The edge device is trained by data sets of workers not wearing personal protective equipment by machine learning which helps in recognizing whether a worker has worn safety wearables or not.
In case of absence of any of the personal protective equipment, the edge device collects data in the form of video and sends it to the monitoring unit (250) in case of any worker not wearing any of the personal protective equipment. The monitoring unit comprises of a RF modem (300) to receive data from the edge device, a computing unit (301) and a display (302) to display and aware the concerned authority of rules being flouted by the worker. Based on the data received on the display of the monitoring unit, the concerned authority can take suitable action against the worker and warn the same of repeating the mistake again. The present invention does not rely on internet or Wi-Fi facilities and can be used in remotest construction sites devoid of mobile network signals and internet or Wi-Fi facilities.
Best Method of working:
A system of edge devices (200) will be installed at suitable locations with unobstructed view to cover the construction site. The camera (100) of the edge devices (200) will continuously collect data in the form video of the workers at the construction site. This collected data will be analyzed by the Computing Unit (101). The edge device is trained by data sets of workers not wearing personal protective equipment by machine learning which helps in recognizing whether a worker has worn safety wearables or not. In case of any non-compliance to wear the personal protective equipment, the Computing Unit (101) will send the data to the Monitoring Unit (250) through RF modem (102) and also activate the Alarm System (102). The alarm system (102) consists of hooters and red LEDs at suitable locations of the construction site to warn the worker. The alarm system (102) will warn the worker by turning on hooter and red LEDs to warn the worker.
The data sent by the Edge Device (200) will be received by RF Modem (300) of the Monitoring Unit (300). The Monitoring Unit (300) with the help of Computing Unit (301) will display the received data in the form of picture and beep to the concerned person in the monitoring unit (300). The concerned person can then be able to take suitable action against the worker and/or warn him of repeating the same mistake again in the future.
ADVANTAGES OF THE INVENTION:
