Description:BACKGROUND
Field of Invention
[001] Embodiments of the present invention generally relate to tracking of employees and/or workers and particularly to a construction site management system and a method using integrated tags at ultra high frequency radio frequency identification band.
Description of Related Art
[002] Construction sites can be hazardous and challenging environments to work in, with workers often exposed to various risks and dangers. Keeping track of workers' movements and ensuring their safety is a crucial aspect of managing a construction site. However, monitoring workers' activities on-site can be difficult, especially when they are spread across a large area of a construction site.
[003] Existing solutions such as CCTV cameras and security personnel are useful but have limitations in terms of monitoring the location and movements of individual workers. Moreover, these solutions are not efficient for the large area of the construction site and are not cost-effective, especially for small construction sites. To overcome these limitations, there is a need for a more efficient and cost-effective solution that can track the movements of individual workers in real-time, especially in the large areas of the construction sites. Furthermore, this could be achieved by the utilization of wearable trackers.
[004] The wearable trackers are designed to be compact, lightweight, and easy to wear, and they can be attached to the workers' clothing or safety gear. The trackers use advanced sensors and wireless technology to transmit the workers' location and movements to a central monitoring system. The central monitoring system further displays the location of each worker on a digital map in real-time, enabling site managers to monitor and manage workers' movements more efficiently. While the wearable trackers use advanced sensors and wireless technology, accuracy can be affected by various factors such as an environment, a signal interference, and a quality of the sensors, themselves. This can lead to inaccurate location data and potentially compromise the safety of workers if they are not in the correct location on the digital map. Also, with the wearable trackers, the workers may feel uncomfortable wearing the tracking device that tracks their location and movements, leading to concerns about privacy and potential misuse of data. Therefore, it is also important to ensure that workers' privacy is protected and that the data collected is used only for its intended purposes. Furthermore, the wearable trackers can help to monitor and manage the workers' movements, these devices do not provide information about other inventories such as materials, equipment, or tools. Separate systems need to be implemented to track and manage these assets, which can add complexity and cost to the overall management of the construction site.
[005] There is thus a need for an improved and advanced construction site management system that can administer the aforementioned limitations in a more efficient manner.

According to embodiments of the present invention, the predefined format of the timestamp may be, but not limited to, a date, a time, a day, and so forth. Embodiments of the present invention are intended to include or otherwise cover any format of the timestamp that may be attached with the maintained track record of the trackable matters 102, including known, related art, and/or later developed technologies. Upon maintenance of the track record of the trackable matters 102, the data logging module 206 may transmit an activation signal to the data transmitting module 208. In an embodiment of the present invention, the data transmitting module 208 may be configured to be activated upon receipt of the activation signal from the data transmitting module 208. the data transmitting module 208 may be configured to transmit the maintained record to the web application 128 installed on the computer device 126, in an embodiment of the present invention. In an embodiment of the present invention, the data transmitting module 208 may further be configured to display a working zone of the trackable matters 102 on the web application 128 installed on the computer device 126. The working zone of the trackable matters 102 may be displayed based on the detected geographical location or the working zones by the readers 120 placed on the predefined zones of the construction site, in an embodiment of the present invention.
[0066] FIG. 3 depicts a flowchart of a method 300 for managing trackable matters 102 using the system 100, according to an embodiment of the present invention.
[0067] At step 302, the system 100 may install the integrated tags 104 tunable at Ultra High Frequency Radio Frequency Identification (UHF RFID) ranges on the trackable matters 102 of the construction site.
[0068] At step 304, the system 100 may receive information related to each of the read integrated tags 104 from the readers 120.
[0069] At step 306, the system 100 may fetch the unique Electronic Product Code (EPC) from each of the read integrated tags 104.
[0070] At step 308, the system 100 may detect the geographical location or the working zone based on the received information related to each of the read integrated tags 104.
[0071] At step 310, the system 100 may maintain the track record of the trackable matters 102 based on the fetched unique Electronic Product Code (EPC), and the detected geographical location or the working zone.
[0072] At step 312, the system 100 may maintain the maintained record to the web application 128 installed on the computer device 126.
[0073] While the invention has been described in connection with what is presently considered to be the most practical and various embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims.
[0074] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined in the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements within substantial differences from the literal languages of the claims. , Claims:CLAIMS
