Monitoring and alarming device and method for personnel intrusion in working area of construction machinery

Abstract

The invention discloses a monitoring alarm device and method for personnel intrusion in a construction machinery working area. The device comprises a main monitoring alarm device installed on a construction machinery working in a construction warning area and a slave monitoring alarm device worn on a construction worker working outside the construction warning area, wherein an intrusion sensing device is used for sensing the existence of personnel or a moving target in a construction warning area and sending an intrusion signal to a main monitoring alarm controller; the main monitoring alarm device comprises a main monitoring alarm controller, an intrusion sensing device, a wireless signal transmitting module, a main monitoring alarm module and a main monitoring alarm power supply; and the slave monitoring alarm device comprises a slave monitoring alarm controller, a slave monitoring alarm module, a wireless signal receiving module and a slave monitoring alarm power supply. The device is used for carrying out two-way monitoring and alarming on workers inside and outside the working area of the construction machinery when the workers intrude into the working area of the construction machinery, and a corresponding monitoring and alarming method is provided.

Description

technical field [0001] The invention relates to the technical field of intrusion alarms in construction areas, and more particularly, to a monitoring alarm device and method for personnel intrusion in construction machinery working areas. Background technique [0002] Most of the current construction safety monitoring is only carried out by installing cameras on site. The more advanced construction safety monitoring methods and devices are to set up multiple peripheral monitoring devices around the construction area. The peripheral monitoring devices include visible light cameras and infrared cameras. The method of breaking into construction areas is to install warning horns on the basis of safety monitoring devices on construction machinery. When the construction machinery starts, the driver presses the vehicle horn to remind surrounding construction workers to avoid. This method is a unilateral warning, mainly prompting the driver, and the driver is not sure whether there ...

AI Technical Summary

Problems solved by technology

This method is a unilateral warning function, which mainly reminds the driver, but the driver does not know whether there are people in the blind area of ​​the surrounding vision, so he can only actively avoid the vehicle through the surrounding people; The workers in the mechanical work area are prone to mechanical injuries if they do not hear the horn warning due to the noise or other factors on site
