The technical solution of the utility model is: a kind of combination instrument of the diesel fork lift truck based on CAN bus, comprise meter hand and telltale, the input end of described telltale is connected with controller, described controller interactive mode is connected with CAN bus transceiver, and described CAN bus transceiver is connected with Engine ECU by CAN bus; The mouth of described controller is connected with respectively warning device and driving circuit, and described driving circuit drives described meter hand to rotate by stepping motor.
Further, described controller interactive mode is connected with random access memory.
Further, the input end of described controller is connected with fuel level sensor for detection of diesel fork lift truck fuel oil, the mouth that detects the temperature sensor of water temperature respectively.
Further, the input end of described controller is connected with switch circuit, described switch circuit comprises fault alarm switch, neutral switch, pole changer, seat switch, air filter switch, the charging indicator cock of diesel fork lift truck, and the signal of above-mentioned each switch exports controller to through switch circuit and carries out Treatment Analysis.
Further, the working power of described controller, telltale, CAN bus transceiver, warning device, driving circuit is to be all to be provided by power module of voltage regulation.
Further, described warning device refers to LED Warning light and buzzer phone.
The utility model middle controller is selected existing product, and its model is NUC130RD2CN.Controller receives the relevant information from Engine ECU by CAN bus transceiver, also gathers the various on-off signals on fork truck simultaneously, and the work of driving LED Warning light, to show the running state of current fork truck.When breaking down, controller not only driving LED Warning light and buzzer phone is reported to the police, and failure code is shown in real time on LCD display simultaneously.So can read clearly the failure message of car load and watch LED Warning light to carry out the classification of failure judgement information intuitively, fast by telltale, thereby it be timely with maintenance, comprehensive to reach fault discovery.And when fault is serious, controller drives engine stop to work by CAN bus transceiver, CAN bus, Engine ECU.
In addition, by fuel level sensor and temperature sensor, gather and be sent to controller after the oil level of diesel fork lift truck fuel oil and water temperature signal and process, and driving the pointer of instrument to carry out rotation work by driving circuit Driving Stepping Motor, the angle that its pointer rotates shows oil level and temperature accurately.When temperature higher than or oil level during lower than setting value, LED Warning light carries out display alarm; Temperature is during higher than maxim, buzzer warning.
CAN bus transceiver is selected TJA1050, and CAN bus transceiver receives the work state information of driving engine by CANL and CANH twisted-pair feeder, and is sent to controller by CANTX and ACNRX.
Random access memory is selected FM25040, for subcontrol, stores data, has ensured the storage space of failure code, and has realized power-off protection function.
Telltale is LCD12864C telltale, is mainly used in the engine behavior information that real-time display control switch receives.
So the combination instrument of the utility model based on CAN bus, utilize SAEJ1939 communication protocol, the combination instrument of realizing in Engine ECU and the utility model communicates, by driving circuit Driving Stepping Motor, drive meter hand to rotate, from the telltale of instrument face plate, read clearly the failure message of car load, and can be undertaken intuitively by LED Warning light, the classification of failure judgement information rapidly, realize timely discovery and the quick solution of fault, and stop where necessary the operation of driving engine, make driving engine can access on-call maintenance, avoid damaging, increasing service life of engine.Also can be by parameters such as the water temperature in CAN bus collection forklift engine system, fuel levels, and without separately connecing sensor, car load also can be realized the plug and play of other control units in CAN bus, for expanding from now on fork truck function and technology upgrading, provides convenience.
