Description
Technical field
The utility model belongs to the Diesel Engine Control technical field, relates to a kind of mechanical governor Ji Xietiaoxie auxiliary device of monoblock pump diesel engine.
Background technique
The mechanical governor Ji Xietiaoxie of monoblock pump diesel engine does not possess long-range analog amount and digital quantity speed-regulating function at present.For those, to the speed governing performance requirement, not very high as a rule, but need to be concerning diesel engine carries out the user of long-range analog amount and the speed governing of number switch signal, mechanical governor Ji Xietiaoxie can't complete at present.
Although current digital governor can meet above-mentioned functions, realize long-range analog amount and digital speed-control, it is expensive a lot of that its price is wanted with respect to mechanical governor Ji Xietiaoxie.
Therefore, be badly in need of at present a kind of simple its mechanical governor Ji Xietiaoxie auxiliary device with low cost.
The model utility content
In view of this, the purpose of this utility model is to provide a kind of mechanical governor Ji Xietiaoxie auxiliary device of monoblock pump diesel engine, by this device, can allow the mechanical governor Ji Xietiaoxie of monoblock pump diesel engine realize the speed-regulating function of long-range analog signals and remote digital switch signal.
For achieving the above object, the utility model provides following technological scheme:
A kind of mechanical governor Ji Xietiaoxie auxiliary device of monoblock pump diesel engine, comprise microcontroller, long-range raising speed signal controller, long-range signal to reduce the speed controller, long-range analog input signal controller, servo-system drive circuit, servo-system and speed feedback device; Microcontroller is connected with long-range raising speed signal controller, long-range signal to reduce the speed controller, long-range analog input signal controller respectively; Microcontroller is connected with the servo-system drive circuit, and the servo-system drive circuit is connected with servo-system again; Microcontroller also is connected with the speed feedback device.
Further, described microcontroller adopts electronic control unit ECU.
Further, described long-range raising speed signal controller and long-range signal to reduce the speed controller are number switch.
The beneficial effects of the utility model are: the mechanical governor Ji Xietiaoxie that the mechanical governor Ji Xietiaoxie auxiliary device of monoblock pump diesel engine described in the utility model not only can auxiliary monomer pump diesel engine is realized the speed-regulating function of long-range analog signals and remote digital switch signal, and this apparatus structure is simple, cheap, can be advantageously applied in industrial production.
The accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is structural representation of the present utility model, as shown in the figure, this device comprises microcontroller 1, long-range raising speed signal controller 2, long-range signal to reduce the speed controller 3, long-range analog input signal controller 4, servo-system drive circuit 5, servo-system 6 and speed feedback device 7; Microcontroller 1 is connected with long-range raising speed signal controller 2, long-range signal to reduce the speed controller 3, long-range analog input signal controller 4 respectively; Microcontroller 1 is connected with servo-system drive circuit 5, and servo-system drive circuit 5 is connected with servo-system 6 again; Microcontroller 1 also is connected with speed feedback device 7.
In the present embodiment, microcontroller 1 adopts electronic control unit ECU, and long-range raising speed signal controller 2 and long-range signal to reduce the speed controller 3 are number switch.The specific works process of this device is as follows: raising speed control signal or reduction of speed control signal that ECU receiving remote raising speed signal controller 2 or long-range signal to reduce the speed controller 3 send over, ECU controls servo-system drive circuit 5 according to this signal, servo-system drive circuit 5 is controlled servo-system 6 and is carried out positive movement or reversing motion, and servo-system 6 is to be connected with the Speed Setting mechanism of the mechanical governor Ji Xietiaoxie of diesel engine, thereby can change the speed set point of mechanical governor Ji Xietiaoxie, reach the purpose of remote.On the other hand, when ECU receives the input signal (can decide by the setting to ECU current signal or voltage signal) of long-range analog input signal controller 4, according to the size of its numerical value determine speed set point the number, simultaneously, the actual speed of the diesel engine fed back in conjunction with speed feedback device 7, ECU judges whether the rotating speed of diesel engine reaches speed set point, and control servo-system drive circuit 5 according to judged result, and then control servo-system 6 and carry out positive movement or reversing motion.
Finally explanation is, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from the utility model claims limited range.
