, Description:FIELD OF THE INVENTION:
The present invention relates to a. The present invention more particularly relates to a tower crane safety management system using IOT.
BACKGROUND OF THE INVENTION:
In recent years, the tower crane has been widely used in lots of application in the construction industry, by its good vertical transportation ability. There are about 700000 tower cranes running in domestic construction site, with a 20-30 thousand units increase per year. However, kinds of tower crane operation safety accidents occur frequently, causing heavy damage to life and property, and it has been up to 30% of site major workplace accidents. Major cause is kinds of irregularities, the overload operation. So we should take some effective means, to supervise the operation and avoid similar accidents.
With the continuous development of network technology, it’s possible to remotely monitor large industrial production in real-time. Through the remote real-time monitoring, regulatory departments don’t have to monitor the running status of equipment on the scene.

It often requires multiple tower cranes to work together in the process of construction. However, due to the factors such as unreasonable optimal configuration of tower cranes, lower collaboration efficiency and unable to issue warning signals when encounter dangerous situations, construction progress would be affected or even lead to construction incidents. Therefore, the real time of data transmission was relatively poor. When there were obstacles, the packet loss rate of data transmission was even greater and the stability was also greatly reduced. To solve the above problems, this paper used Radio Frequency Identification (RFID) technology to realize the wireless communication of the towers group. Compared with Zigbee technology, RFID technology has the advantages of non-contact transmission, penetrability, no barrier reading and strong anti-interference ability. These all improved the accuracy and real time of data transmission.
So there is a need for a tower crane safety management system using IOT. The present invention is an efficient and a safe system for monitoring the real-time work status of single tower crane and between each other. The present invention is applied RFID technology to the anti-collision system between two tower cranes and wireless communication system of the tower cranes group. As the important part of the perception layer of the Internet of Things, the application of RFID technology in wireless communication system of tower cranes group could improve the efficiency of the construction. It also ensured the safety of the construction.

DETAILED DESCRIPTION OF THE INVENTION WITH RESPECT TO DRAWINGS:
The present invention is a tower crane safety management system using IOT to provide a tower crane safety management system using IOT. The present invention provides an efficient and a safe system for monitoring the real-time work status of single tower crane and between each other. The present invention provides an anti-collision system with the system between two tower cranes and wireless communication system of the tower cranes group and the application of RFID technology in wireless communication system of tower cranes group could improve the efficiency of the construction.
In one embodiment, for individual tower cranes, the status information of trolley, jib and tower can be detected by a set of customized sensors. To measure the position of the trolley and the jib, displacement transducers are used for the horizontal and vertical directions. To detect the status of tower body, load, and tilt and wind speed suitable sensors are applied for the integrated information. All the results from sensors are transmitted through signal lines to a central control system (the database of the website), installed in the driver’s operating room. Since all the sensors are installed on the tower within 10 m distance from the central node, they can be connected via the wired way. For tower crane groups within an overlapping working area, there could be more than three cranes in the work area, making it very difficult for the driver to pay attention to all the other adjacent cranes.
In another embodiment, the status of the whole group needs to be transmitted to each tower crane for the anti-collision system for conveniently transmitting information in a wired way. Therefore, wireless communication is a necessary alternative in this particular situation, which can avoid interruptions during the construction process and realize relatively stable communication between the tower crane groups.
Through the signal lines, the Tower Crane Safety control system acquires data from all sensors installed at the key parts of tower cranes. Meanwhile, the real-time status of each tower crane is reported to a Local Monitoring Terminal (LMT) through a wireless network. The main functions of LMT are to act as a digital repeater for each control system and act as data flow controller, and as implementer of the wireless network protocol. Meanwhile, LMT is used to communicate with the Remote Supervision Platform (RSP) server. RSP acquires data from LMT in each worksite through the General Packet Radio Service (GPRS) or the mobile (3G) Internet.
In another embodiment, RSP can be easily connected via the Internet using safety monitoring system of the present invention. Using the system of the present invention, Supervisors can register a tower crane and determine its real-time status as well as historical data of all the tower cranes in a certain area. The Supporting Layer can fulfill the thinking, identifying and decision-making tasks as a functional brain of the IoT. The core component of the Supporting Layer is the Anti-Collision Controller (ACC) for the individual tower cranes. As a processing device, ACC is integrated in the control system that is directly connected to various sensors via wired links. Therefore, stable and high-speed transmission can be fulfilled. Raw data are transmitted from sensors to control system; processed raw data are transmitted from the control system to the LMT by a wireless network; processed data are transmitted from the LMT to the RSP by GPRS or 3G Internet. As a result, the total amount of data transmission of the SMS-TC is reduced significantly in this wired plus wireless transmission method. Furthermore, the energy consumption for the transmission is reduced and the energy conservation of the system is improved, especially for the wireless equipment.
