In this case, when the ambient brightness changes, the maximum driving speed of the forklift cannot be effectively limited according to the luminous flux
For example, when the ambient brightness (luminous flux) is lower than a certain value, for the sake of safety, it is often necessary to limit the maximum driving speed, but currently only rely on the driving experience and consciousness of the forklift driver to reduce the driving speed. On the other hand, due to the lack of experience or carelessness of the driver, the driving speed is often not reduced or the degree of reduction is not enough, resulting in accidents

The invention discloses a forklift maximum speed control system and method based on ambient brightness. The system comprises a forklift driving motor, a controller, a photosensitive sensor and a direct current power supply, wherein a positive electrode of the direct current power supply is connected with a first pin of the controller so as to provide electricity, a negative electrode of the directcurrent power supply is connected with one end of the photosensitive sensor, and a second pin of the controller is connected with the other end of the photosensitive sensor so as to control the maximum speed of the forklift driving motor according to the voltage change of the photosensitive sensor. According to the system, the maximum speed of the forklift driving motor can be automatically adjusted according to the ambient brightness, so that safe driving of a forklift is guaranteed.
Description
technical field [0001] The invention relates to the field of forklift safety, in particular to a system and method for controlling the maximum speed of a forklift based on ambient brightness. Background technique [0002] Currently, the maximum speed of the forklift is often set in advance, and it will not be automatically adjusted according to the environmental conditions during the driving of the forklift. In this case, when the ambient brightness changes, the maximum driving speed of the forklift cannot be effectively limited according to the luminous flux. For example, when the ambient brightness (luminous flux) is lower than a certain value, for the sake of safety, it is often necessary to limit the maximum driving speed, but currently only rely on the driving experience and consciousness of the forklift driver to reduce the driving speed. On the other hand, due to the lack of experience or carelessness of the driver, the driving speed is often not reduced or the degre...
