The invention relates to a diesel fork lift truck driving safety control device, which comprises a controller. The M1 port of the controller is connected with one end of a third fuse F3;ports M2, M3,M4, M5, M6 and M7 are respectively connected with one end of a seat switch S2, one end of a safety belt switch S3, one end of a parking brake switch S4, one end of a forward direction switch S5, one end of a middle direction switch S6 and one end of a backward direction switch S7 in a one-to-one correspondence manner; the M9 port of the controller is connected with one end of the buzzer; the M10 port of the controller is connected with one end of a warning lamp; theM11 and M12 ports of the controller are connected with a vehicle speed detection unit; the M13 port of the controller is connectedwith one end of a brake pressure sensor; and the M14 and M15 ports of the controller are respectively connected with a backward electromagnetic valve Y2 and a forward electromagnetic valve Y1 in one-to-one correspondence. In the running process of the whole vehicle, if the running speed of the whole vehicle exceeds the safe vehicle speed, the warning lamp and the buzzer are used for prompting, the controller outputs signals to the engine through the CAN bus, the engine adjusts the rotating speed, and therefore the running speed of the whole vehicle is limited, and safe running of the whole vehicle is guaranteed.
本发明涉及一种内燃叉车行车安全控制装置,包括控制器,其M1端口与第三保险丝F3的一端相连,其M2、M3、M4、M5、M6、M7端口分别与座椅开关S2、安全带开关S3、停车制动开关S4、前进方向开关S5、中位方向开关S6、后退方向开关S7的一端一一对应相连,其M9端口与蜂鸣器的一端相连,其M10端口与警示灯的一端相连,其M11、M12端口与车速检测单元相连,其M13端口与制动压力传感器的一端相连,其M14、M15端口分别与后退电磁阀Y2、前进电磁阀Y1一一对应相连。在整车行驶中,如果整车行驶速度超过安全车速,通过警示灯和蜂鸣器提示,控制器通过CAN总线输出信号给发动机,发动机调整转速从而限制整车行驶速度,以保证整车安全行驶。
