Construction site safety early warning system and method

Abstract

The invention provides a construction site safety early warning system and method. The system comprises: emitters which are respectively arranged in different areas of a construction site and are used for continuously emitting two beams of infrared sector laser and carrying out horizontal 360-degree rotary scanning on an external space; a receiver which is used for receiving the infrared sector laser emitted by the emitter, demodulating light source information of the infrared sector laser and recording receiving time, receiving the infrared synchronizing signal, recording the receiving time, calculating three-dimensional coordinate data of the current position according to the light source information, uploading the three-dimensional coordinate data to a control center, receiving the early warning information, and giving out an early warning sound; and a control center which is used for providing an infrared synchronizing signal for the whole system, receiving the three-dimensional coordinate data, judging the relationship of the spatial positions among the receivers according to a security algorithm, and sending out early warning information. The method has the advantages of being high in positioning precision and capable of reducing construction safety accidents, and is suitable for the technical field of capital construction engineering.

[0002] In recent years, with the development of economy and society, the status of the infrastructure industry in my country's national economy has been increasing day by day. However, as a place where construction and production factors are concentrated on the infrastructure construction site, its operating environment changes all the time, and there are great potential safety hazards;

[0003] On the one hand, the environmental conditions of the infrastructure construction site are complex and changeable, and there are a large number of open-air and high-altitude operations; the construction process involves various operating processes such as construction components, construction machinery, operating equipment, and transport vehicles. The current technology Conditions are difficult to effectively identify, track and monitor various unsafe factors existing in the on-site environment

[0004] On the other hand, there are a large number of construction personnel and high mobility of personnel. The construction process will also involve multiple types of comprehensive cross-operation and the operation of large-scale mechanical equipment. Mechanical construction and manual operation exist at the same time; existing supervision methods are difficult to control and manage The scope of work and work behavior of all staff;

[0005] The existence of the above factors makes it difficult to conduct comprehensive and real-time monitoring and management of the construction site under the current on-site management and command measures, and it is also difficult to effectively prevent construction safety accidents, making the infrastructure industry one of the most accident-prone industries

[0006] With the continuous development of the computer industry, the intrusion detection and early warning of personnel in dangerous areas through infrared positioning technology has been applied to most industries with dangerous operations; The mainstream positioning technology has the following problems:

[0007] 1. The positioning accuracy is not enough;

[0008] 2. Insufficient real-time performance;

[0009] 3. High cost;

[0010] 4. The number of terminals is limited
