With the acceleration of economic development in our country,the construction industry has made great progress and has become an important pillar of China’s economic and social development. However the frequent occurrence of construction safety accidents sounded the alarm for all construction workers. The safety control measures of construction site mainly depends on artificial regulation, but the construction of civilization of field personnel is low, safety awareness and self-protection awareness is not enough, plus the construction site perplexing environment, lead to different degrees of construction site security risks exist, many risk sources have no real control.Strengthen the construction of the construction site safety monitoring, to do preventive measures to ensure the safety of people is imperative.Introduces the current situation of the safety management of the construction site,analyzes the existing problems in the construction management and the limitations of the management methods. The types of safety accidents are classified and the causes of safety construction are discussed. In order to solve the highest casualties at the top of the falling accident as the focus of the follow-up study.Introduces the relevant content of the CAN bus protocol, analyzes the working principle and the basic structure of the data. By using the principle of ultrasonic ranging system is designed based on CAN bus transmission, selection presents a design scheme of the hardware of the system, and how to build a CAN bus signal list were explained in detail, using CAN Editor to simulate the design scheme. Introduces the structure, working principle and related indoor positioning technology of RFID system. Based on the field measurement, the signal attenuation factor is determined, and the model of wireless signal propagation in free space is determined. The use of CC2530 development platform, using the received signal strength indicator (Received RSSI Signal Strength Indication) method to design positioning scheme, establish a ranging model to simulate the system to calculate the average value of the error.In the actual construction site, the construction workers verify the feasibility of the system in the normal work of the sudden emergence of unsafe behavior. The test results show that the study of this paper has a certain effect on improving the level of construction safety management, reducing the accident rate and ensuring the health of the construction workers. |
