Embodiment Construction

[0029] Such as figure 1 As shown, it is a schematic diagram of the application environment of the early warning system for falling objects in the present invention. In this embodiment, the early warning system 21 for falling objects in the sky operates in a safety protection device 2 . The safety protection device 2 also includes a memory 20 , a controller (such as a microprocessor) 22 , a camera 23 , an acceleration sensor 24 and a warning device 26 connected through signal lines and data lines. In this embodiment, the safety protection device 2 is an engineering helmet.

[0030] The camera device 23 is used to acquire scene images above the user's head at preset intervals (such as 0.1 second), and store the acquired scene images in the memory 20 . The falling object warning system 21 detects falling objects in the acquired scene image, and when it is judged that the user may be injured by the falling object, the warning device 26 is automatically activated to give an alarm...

Abstract

An overhead falling object early-warning method comprises the following steps that scene images shot by a camera device of a safety protecting device, and the moving direction and the moving speed, detected by an acceleration sensor, of a user are obtained every preset interval time; a falling object is detected in the detected scene images; when the falling object is detected in the scene images obtained, whether the user can be wounded by the detected falling object or not is judged according to the detected position of the falling object, and the moving direction and the moving speed of the user; when the fact that the user can be wounded by the detected falling object is determined, the fact that a warning device needs to be started in the safety protecting device is determined; the warning device is started to conduct warning. The overhead falling object early-warning system and method can be used for detecting whether the falling object appears above the user of the safety protecting device or not in real time.

Description

technical field [0001] The invention relates to a monitoring system and method, in particular to an early warning system and method for falling objects in the sky. Background technique [0002] At present, most engineering personnel in dangerous places such as construction have not set up relevant hazard warning notification mechanisms. When high-altitude objects in the construction site accidentally fall or other dangerous situations that may endanger the safety of the engineering personnel below, most of them can only rely on the on-site engineering. The personnel noticed it by themselves, and shouted loudly to warn the engineering personnel below to dodge. [0003] However, since construction sites are often filled with high-decibel mechanical noise, engineering personnel may not be able to hear other people's calls, or fail to detect relevant dangerous situations in time, resulting in engineering personnel being unable to dodge in time and being injured by falling object...
