Design of Wireless Intelligent Monitoring System for Inner Suspension Inner Backstay Derrick for Tower Erection in Sections

The derrick system is a decisive factor affecting the safety of Inner Suspension Inner Backstay Derrick for Tower Erection in Sections. However, due to its complex stress and difficulty in real-time perception, the erection of the tower assembly is too difficult and even causes accidents. In this paper, a wireless intelligent monitoring system based on wireless sensor network and Internet of Things technology for Inner Suspension & Inner Backstay Derrick for Tower Erection in Sections is proposed. Through the analysis of the technological process of tower erection, the weak points of the derrick system are obtained, and the function principle and module composition of the system are clarified. According to the force, tilt, wind speed, height, distance and other data characteristics of the derrick and its Backstay system, corresponding sensors are selected for real-time data monitoring and acquisition. In addition, in view of the characteristics of wide distribution and multiple levels of monitoring points, LoRa tree-type networking mode is adopted to form a wireless transmission mode in which the above devices are the total nodes of the network. The system adopts array patrol and reply communication mode, each channel is used in an orderly way when passing through, the data delay is controlled within microsecond level, and the value of each danger point is controlled within the safe range through the limitation warning function, so as to ensure the safety and stability of the whole construction process.
