Abstract
Provided is a device for reminding replacement of engine oil, belonging to the automotive electric appliance field. The device is characterized by comprising a power module, a control ECU, a single-chip microcomputer, a capillary viscometer, an analog quantity input channel, a digital quantity input channel, a pH measurement transmission module, an air core inductor, a bridge and a display, wherein the pH measurement transmission module is connected with the single-chip microcomputer, the air core inductor is connected with the single-chip microcomputer via lead wires, the capillary viscometer is connected with the display via lead wires, and the display is connected with the single-chip microcomputer which is in connection with a warning lamp via the control ECU. By automatically analyzing whether ingredients of engine oil exceed the prescribed engine oil indexes, the device can remind drivers of timely replacing engine oil.
Description
Technical field
The utility model relates to a kind of engine motor oil and changes alarm set, belongs to the automobile electrical appliances field.
Background technique
Science is confirmed the automobile engine lubricating oil phase, runs well for motor car engine, increase the service life, and energy saving, reducing cost has important practical significance.Yet according to investigations, the Consumer is for differentiating the machine oil oil degree that degenerates, and oil changing interval is only made judgement with the machine oil outward appearance at interval by rule of thumb, though this is convenient and simple, and also science not comprehensively not.
At present, domesticly remind the Consumer in time to change oil by regulation vehicle driving mileage number basically.Yet in actual the driving, road conditions, vehicle condition, machine oil quality etc. all can influence the oil exchange cycle, especially at urban drive; Frequent starting, parking all can aggravate engine scuffing; Accelerate oil pollution, in therefore actual the use, the drain period must require to shorten than regulation.The method of the quality of checking up Engine oil mainly contains the filter paper spot test, with oil droplets in the fuel tank on oil filter paper, the diffusion of observing the machine oil diffusion ring after in the time of a section.Therefore this operation length consuming time, and testing precision and efficient are all low.
Summary of the invention
The purpose of the utility model is to address the above problem, provide a kind of simple in structure, cost is low, in time reminds more change engine oil of driver, in case influence the device of the normal operation of automobile, and through showing that corresponding index driver assistance person analyzes the operating conditions of motor.Specifically realize through following technological scheme:
A kind of engine motor oil is changed alarm set; Comprise that power module, control ECU, single-chip microcomputer, capillary viscosimeter, analog input channel, digital quantity output channel, pH measure transmitting module, air core inductor, electric bridge, display device; Said pH measures transmitting module and is connected with A/D converter through the analog input channel, and output terminal is connected with single-chip microcomputer through the digital quantity output channel, and said air core inductor is connected with single-chip microcomputer through lead; Said capillary viscosimeter is connected with display device through lead; Said display device is connected with single-chip microcomputer, and said single-chip microcomputer is connected with beacon through control ECU, and this device is installed in the sump interior location.
The utility model is the advantage of existing technology relatively:
1, whether surpasses the machine oil index of regulation through automatic analytical engine oil component, remind the driver in time to change oil, saved the trouble of sample detecting, improved testing precision and efficient.Avoided the driver only to judge by rule of thumb simultaneously, and too damaged engine components or cause the more waste of change engine oil too early.
2, testing result has contained main three criteria for changing oils, and the driver can pass through data display, judges the operation conditions of motor miscellaneous part.
Description of drawings
Fig. 1 is that the said a kind of engine motor oil of the utility model is changed alarm set layout schematic representation.
Embodiment
The 1-power module; 2-pH measures transmitting module; The 3-single-chip microcomputer; The 4-air core inductor; The 5-display device; The 6-capillary viscosimeter; 7-controls ECU; The 8-beacon.
Below in conjunction with embodiment's accompanying drawing the utility model is further specified.
As shown in Figure 1, the described engine motor oil of the utility model is changed alarm set, comprises that power module 1, pH measure transmitting module 2, single-chip microcomputer 3, air core inductor 4, display device 5, capillary viscosimeter 6, control ECU 7, beacon 8.Described pH measurement transmitting module 2 passes to single-chip microcomputer 3 with the pH value of machine oil through the analog input channel, and single-chip microcomputer 3 converts the pH value signal to digital signal through A/D, utilizes display device 5 to demonstrate pH value; Said air core inductor 4 passes to single-chip microcomputer 3 with iron content with voltage signal, and single-chip microcomputer 3 is handled this signal, utilizes display device 5 to show iron content; Said capillary viscosimeter directly passes to the kinematical viscosity that display device 5 shows machine oil with measured value through lead.When having one to surpass limit value in these three indexs, open beacon automatically through control ECU and remind the occupant.
