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 system and method for controlling the maximum speed of a forklift based on ambient brightness. The system includes: a forklift drive motor, a controller, a light sensor and a DC power supply; the positive pole of the DC power supply and the first lead of the controller Pins are connected to provide power; the negative pole of the DC power supply is connected to one end of the light sensor; the second pin of the controller is connected to the other end of the light sensor to The voltage change on the sensor controls the maximum speed of the forklift drive motor. The invention can automatically adjust the maximum speed of the driving motor of the forklift according to the brightness of the environment, thereby ensuring safe driving of the forklift.
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...
