The invention provides a fault monitoring method for a telescopic boom forklift truck, which is applied to the fault monitoring system for the telescopic boom forklift truck, and comprises the following steps:
starting the telescopic boom forklift;
the external detection unit and the internal detection unit of the detection module operate simultaneously, the external detection unit acquires environment parameter information and feeds back the environment parameter information to the data storage and processing module, the internal detection unit acquires vehicle data and feeds back the vehicle data to the data storage and processing module, and the data storage and processing module stores each item of acquired data and divides each item of data into fault data and operable data;
when the data storage and processing module obtains fault data, the fault data are transmitted to the fault preprocessing module, and the fault preprocessing module receives the fault data and displays a fault processing mode corresponding to a position of the telescopic boom forklift which generates the fault data in a display screen of a cab of the telescopic boom forklift; when the fault preprocessing module does not give out a corresponding fault processing mode, the emergency communication module establishes communication connection between the cab and the after-sales maintenance system, and sends all parameter information detected by the detection module to the after-sales maintenance system, and a rear end visualization unit of the after-sales maintenance system displays all parameter information detected by the detection module; restarting the telescopic arm forklift after the fault is solved;
when the data storage and processing module does not acquire fault data, the operable grade is divided according to the ratio of the acquired parameter value of the operable data to the prestored preset parameter value, the operable grade information is transmitted to the warning module, and the warning unit warns or controls the warning unit to warn or control the whole vehicle to stop working according to the operable grade information.
In the method, the environment parameter information acquired by the external detection unit comprises, but is not limited to, an external environment temperature, an external environment humidity, an external environment wind power, an operation gradient of the telescopic boom forklift, a single operation duration and a total operation duration of the telescopic boom forklift. The vehicle data acquired by the internal detection unit include, but are not limited to, the luffing angle of the boom, the rotation angle of the turntable, the elongation of the boom, the tire pressure, the load weight, the working current, the working voltage, the component working data, the hydraulic oil quantity, the hydraulic working pressure, the fuel oil quantity, the engine working temperature, the antifreeze capacity, the tail gas concentration and the engine oil quantity.
When the fault data are obtained by the data storage and processing module, for example, the tire pressure parameter value obtained by the internal detection unit is far higher than the preset air pressure parameter value pre-stored by the data storage and processing module, the measured tire pressure parameter value is transmitted to the fault pre-processing module, the fault pre-processing module receives the tire pressure parameter value and displays the corresponding processing mode for reducing the tire pressure in a display screen of a cab of the forklift truck, a control personnel can process the tire pressure according to the processing mode displayed by the display screen, when the fault pre-processing module does not give the processing mode for reducing the tire pressure or the control personnel can not solve the fault according to the given processing mode by the existing conditions, the emergency communication module can be used for establishing communication connection between the cab and an after-sales maintenance system, and transmitting all parameter information detected by the detection module to the after-sales maintenance system, and the after-sales personnel can display all parameter information detected by the detection module aiming at all the parameter information displayed by the after-sales maintenance system and combined with the designated fault position analysis and remote control personnel for processing by the control personnel.
When the data storage and processing module does not obtain fault data, the operable grade is divided according to the ratio of the parameter value of the obtained operable data to the prestored preset parameter value, for example, when the actual fuel quantity detected by the internal detection unit is 98L and the preset standard quantity of the fuel quantity prestored by the data storage and processing module is 100L, the operable grade corresponding to the fuel quantity data is rated as ten grades, and the operable grade is displayed in real time through a display screen in a cab, and the operable grade represents that the fuel quantity meets the operation requirement. When all the operable data meet the operation requirement, the prompting unit provides an operable warning on the display screen; for another example, when the actual fuel quantity detected by the internal detection unit is 5L, the operation level corresponding to the fuel quantity data is rated as one level, the prompting unit controls the alarm unit to warn, operators can timely add fuel according to the warning, and when the actual fuel quantity detected by the internal detection unit is 0 due to the fact that the operators do not timely process the fuel quantity, the prompting unit controls the whole vehicle to stop operating so as to avoid faults caused by continuous operation.
