Industrial Trucks Active Safety

Recently,with the development of economy,the logistics industry are growing rapidly,and the safety requirements for industrial vehicles becomes higher.Also,the traditional security concept is gradually changing,and how to guarantee industrial vehicle work safety has become a social concern.During the increasingly busy production operation,traditional passive technology(such as safety belt)has been unable to effectively protect worker from accident.In order to effectively prevent traffic accidents,and to avoid personal injury and property loss,active safety technology has been paid extensive attention during the design process of industrial vehicles.It is currently the most important issue to improve the active safety of industrial vehicles for most industrial vehicle manufacturers.Firstly,this paper presents an overall design scheme of sensing system,in order to break the trade barriers,which is based on the analysis of domestic and international state of forklift truck industry.This solves the problem that the operation is not standardized,when the driver is operating a forklift,thereby preventing the vehicle accident,avoiding personal injury and property loss.Secondly,this paper illustrates the whole system hardware circuit design by using the master microprocessor chip and the CAN transceiver chip.This is based on the understanding of the characteristics of combustion forklift operating environment,operating mode,etc.The corresponding PCB printed circuit board is designed and drawn by Altium Designer software.Thirdly,the paper introduces the analysis and application of J1939 protocol.The software was developed by using CodeVision AVR C development platform.Both hardware and software design of the whole system has been completed.Finally,this paper validates the outcomes from this study and confirms that they are completely in line with the initial design requirements and the corresponding standards through a series tests,including simulation of the input and output of the actual vehicle by controller on testing bench,software correction,the real vehicle test,the type test and electromagnetic compatibility test.Therefore,the active control system on forklift significantly reduces the vehicle accident,prevents the occurrence of hazards,and ensures that the forklift driver's behaviour is in accordance with the standard operation requirement.At the same time,the active safety technology has broken through the trade barriers and has established its position on international market.
