Problems solved by technology

[0002] Forklift is an indispensable cargo handling equipment in the field of modern logistics. It has the characteristics of simple operation and high efficiency. At present, in the environment where forklifts are used, people and vehicles work together, especially in warehouses. The driver's sight is blocked, so that the driver cannot effectively observe the pedestrians in the surrounding environment of the shelf column. In addition, the vigorous development of electric forklifts in recent years has made the noise of the forklift during work small, and the noise in the working environment covers the sound of the forklift. , It is easy to cause safety accidents caused by the driver’s failure to avoid pedestrians in time. Once a forklift accident occurs, it will lead to serious loss of life and property. How to avoid these working environments where people and vehicles are mixed, the safe use of forklifts has become particularly important. These Various types of lights have been installed in forklifts in recent years, which has played a certain role in protecting pedestrians from finding vehicles, but the reminder to forklift drivers is still not timely and effective. This working environment needs to remind both the driver and the pedestrian

Abstract

The invention relates to a safety protection system and method. The system comprises a controller, a pyroelectric sensing module, a distance sensor module and an audible and visual alarm. The pyroelectric sensor module, the distance sensor module and the audible and visual alarm are all connected with the controller; the pyroelectric sensing module is used for detecting pedestrians and vehicles in the blind area; the distance sensing module is used for detecting a first horizontal distance between a pedestrian and the distance sensor module and a second horizontal distance between a vehicle and the distance sensor module; and the controller is used for controlling the audible and visual alarm to give an alarm according to the first horizontal distance and the second horizontal distance. Therefore, the safety protection system can be used for monitoring the moving conditions of pedestrians and moving vehicles in the blind area range in real time, acquiring the moving distance information of the pedestrians and the vehicles in real time, and reminding the pedestrians and the vehicles in time according to the moving distance information, so that the safety of the pedestrians and the vehicles is ensured.
