Description

Auxiliary lighting method and system for forklift Technical Field The invention relates to the field of forklifts, in particular to an auxiliary lighting method and system for a forklift. Background The forklift is an industrial transport vehicle, and is a variety of wheeled transport vehicles capable of handling, stacking, and transporting goods in pallets over short distances. Before the existing forklift is started, a driver needs to log on the cab to execute related starting operation before the existing forklift is started, if the vehicle is in a dark or insufficient-light environment, the driver needs to be provided with an additional illuminating lamp to illuminate, so that the driver can conveniently find the cab and safely enter the cab when the driver gets on the forklift, the driver can be prevented from stepping on a step to fall, and the potential safety hazard caused by mistakenly touching other switches of the instrument panel due to insufficient light can be avoided in the starting operation executing process. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides an auxiliary lighting method and an auxiliary lighting system for a forklift, which can automatically control an auxiliary lighting lamp to be turned on or turned off under the environment of insufficient light, provide lighting vision for a driver and avoid potential safety hazards. The invention adopts the following technical scheme: An auxiliary lighting method for a forklift truck comprises the steps of monitoring light rays of an environment where the forklift truck is located and whether a human body approaches the forklift truck or not before the forklift truck is started, controlling an auxiliary lamp on the forklift truck to be started to realize auxiliary lighting when the light rays meet set conditions and the human body approaches the forklift truck, detecting whether the forklift truck is started or not after the auxiliary lamp is started, and controlling the time for closing the auxiliary lamp according to whether the forklift truck is started or not. Further, the luminous flux of the environment where the forklift is located is monitored, if the luminous flux is smaller than or equal to a set threshold value, the light meets the set condition, and if the luminous flux is larger than the set threshold value, the light does not meet the set condition.
