The specific embodiment
Introduce the utility model in detail below in conjunction with accompanying drawing:
As Fig. 1 to Fig. 8, electric controller of the present utility model comprises casing 1 and is installed in the interior circuit backboard 2 of this casing, be plugged with a CPU card 3 and at least one I/O card 4 on the described backboard, the quantity of I/O card is according to how many settings rationally of external world's order, and an I/O card can be accepted the inputs of a plurality of extraneous orders; Each described I/O card 4 comprises load module 41, output module 42, inferior CPU43 and first data transmission module 44; Described CPU card 3 comprises host CPU 31 and corresponding second data transmission module of 32, one I/O cards of at least one second data transmission module.In the utility model, described load module 41 comprises frequency conversion reduction voltage circuit 411 and photoelectric isolating circuit 412, two kinds of described first data transmission module, 44 employing 485 chips or CAN buses, and wherein a kind of work, another kind of standby; Described second data transmission module 32 adopts three kinds of 485 chips, 232 chips or CAN buses, wherein a kind of work, in addition two kinds standby; Described output module 42 comprises frequency conversion booster circuit 421.In implementation process, external world's order high-voltage signal step-down frequency conversion that the frequency conversion reduction voltage circuit will be imported, by photoelectric isolating circuit electric signal is converted into optical signal earlier again, then low-voltage signal is imported described CPU by interface circuit, inferior CPU carries out signal to be transferred to backboard by interface circuit by 485 chips behind the simple operation, when the damage of 485 chips or cisco unity malfunction, signal can be given backboard by the CAN bus transfer.485 chips or CAN bus play the translation coding encrypting and it can be transmitted signal.Subsequently, backboard transfers data to described host CPU by 485 other chips through interface circuit, and when the damage of 485 chips or cisco unity malfunction, signal can be given host CPU by 232 chips or CAN bus transfer.485 chips, CAN bus and 232 chips play the effect of translation coding to signal.Then, host CPU carries out computing and makes instruction data, simultaneously the result is existed in the storage chip of memory module 33, and when main CUP damage or cisco unity malfunction, standby host CPU 34 can be finished the work of host CPU.The former road of instruction that host CPU or standby host CPU send is back to time CPU, instruction is after the simple processing of CPU, be transferred to the frequency conversion booster circuit by interface circuit, this circuit carries out frequency conversion to command signal and boosts, and at last the high-voltage signal instruction is transferred to concrete performance element, as the unlatching of oil pump, regulate throttle gate, the unlatching of starter motor, behind a series of start-up operations of unlatching of storage battery etc., locomotive begins to start walking.
The utility model also can be used for for example OBD (On-Board Diagnostics) of fault.As establishing fault-indicating lamp at CPU card and I/O card, if opening, certain blocks when upward CPU goes wrong cisco unity malfunction, that corresponding lamp does not just work, if normally then can be bright; Also can further distinguish the problem that CPU occurs, some problems make indicator lamp show different flickers, and this can be according to the self-defined different problem of the corresponding component units of different flickers that decides; Also can distinguish the voltage of CPU card and I/O card by indicator lamp, correspond respectively to the 3.3V voltage of CPU card and 24V, 5V and the 3.3V voltage of I/O card as different indicator lamps, if corresponding magnitude of voltage then shows red light when not reaching, then show green light when reaching.Like this by the different demonstration situation of each card indicator lamp, just can judge very soon and where go wrong, where be normal, just need not very blindly comprehensively search, not only saved the time, and improved efficient, provide convenience for maintainer's maintenance greatly, the trouble diagnosing of realization locomotive intermediary electrical controller that can be preliminary, analyze and early warning, and instruct personnel to finish the investigation of fault by the display lamp demonstration, realize online investigation fault, having overcome prior art must those of skill in the art search according to figure, anatomize the shortcoming of ability trouble-shooting, make that maintenance is convenient, improved work efficiency.
