The invention discloses a pressure sensor fault diagnosis system, a diagnosis method and a crane. The system comprises a pressure sensor, a vehicle-mounted controller and a vehicle-mounted display, wherein the pressure sensor is arranged at a key pressure detection position on a whole machine, and the pressure sensor is respectively connected with the vehicle-mounted controller and the vehicle-mounted display through a CanOpen bus; the vehicle-mounted controller is used for diagnosing the pressure sensor and outputting a diagnosis result; and the vehicle-mounted display is used for starting brand proprietary confirmation diagnosis, sensor parameter setting and fault code display of the pressure sensor. The method solves the problems that whether the pressure of the crane is abnormal is a sensor fault or the pressure of the whole machine is abnormal is difficult to judge in time, the fault reason cannot be quickly and accurately positioned and the like, meanwhile, the pressure sensor at a key detection point can be prevented from being replaced randomly, and the safety and reliability of the whole machine system are ensured.

    本发明公开了一种压力传感器故障诊断系统、诊断方法及起重机包括布置在整机上车关键压力检测位置处的压力传感器、车载控制器和车载显示器,其中通过CanOpen总线将压力传感器分别与车载控制器和车载显示器相连,车载控制器用于诊断压力传感器并输出诊断结果,车载显示器用于启动压力传感器品牌专有性确认诊断、传感器参数设置和故障码显示。本发明解决起重机压力异常难以及时判定是传感器故障还是整机压力异常,不能快速精准定位故障原因等问题,同时可避免关键检测点的压力传感器被任意替换,保证整机系统的安全性和可靠性。
