Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Just as described in the background section, at present, smoking car has been applied in a lot of technical field, but due to the singularity of its applied environment, its in use, aging due to electric component in car, or other reason, cause it to be easy to break down.And at present because smoking car equipment is accurate complicated, strongly professional, also lack relevant professional Measuring error equipment at present, as passed through manually to go to detect one by one, this detection mode not only inefficiency, and higher requirement be it is also proposed to the technical merit of maintenance personal.
On basis based on above-mentioned research, the utility model embodiment provides a kind of smoking car fault test set, comprise the pressure transducer being arranged on smoking car fuel pump entrance, the pressure transducer of outlet, be arranged on the pressure transducer of smoking car mist oil pump import, for the pressure switch of the speed probe and engine interior lubricating oil pressure that detect engine speed, for mutual inductance transducer and a detecting box of the voltage sensor and starting current that detect starter motor trigger voltage, the signal gathered is sent to detecting box by each described sensor, the signal of described detecting box to each sensor processs and displays after changing.
The fault that the utility model achieves smoking car detects automatically, when not removing equipment, can detect smoking car, and this pick-up unit is high relative to current manual detection efficiency.
In order to enable above-mentioned purpose of the present utility model, feature and advantage more become apparent, and are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here to implement with multiple, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension.Therefore the utility model is not by the restriction of following public embodiment.
As shown in Figure 1, smoking car fault test set, comprise the pressure transducer 1 being arranged on smoking car fuel pump entrance, the pressure transducer 2 of outlet, be arranged on the pressure transducer 3 of smoking car mist oil pump import, for the pressure switch 5 of the speed probe 4 and engine interior lubricating oil pressure that detect engine speed, for mutual inductance transducer 7 and a detecting box 8 of the voltage sensor 6 and starting current that detect starter motor trigger voltage, the signal gathered is sent to detecting box 8 by each sensor, the described signal of detecting box 8 to each sensor processs and displays after changing.
Detect the pressure transducer 1 of fuel pump entrance and the pressure transducer 2 of fuel pump outlet, be respectively used to the inlet pressure and the top hole pressure that detect fuel pump;
The pressure transducer 3 of mist oil pump import is for detecting the pressure of mist oil pump import.
For detecting the pressure switch 5 of engine interior lubricating oil pressure, its working method is: when engine interior lubricating oil pressure reaches certain setting value, it sends a pulse signal to detecting box 8, detecting box 8 shows this signal, when engine interior lubricating oil pressure does not reach certain setting value, it does not send signal.
Engine speed sensor adopts turbo blade cutting passive type speed probe 4, it comprises one group of electromagnet through coil, the two ends of described coil are connected with signal processing circuit, and described signal processing circuit is connected with detecting box, and concrete principle of work is as follows:
Passive type turbo blade cutting speed probe is commonly used to measure turbo blade rotational speed, it is made up of the electromagnet that a group is passed coil, and when the projection proximity transducer magnetic conductor of the turbine gear teeth, magnetic flux increases, when the projection of the turbine gear teeth leaves magnetic conductor, magnetic flux reduces.The motion result of the turbine gear teeth causes magnetic flux to change in time, proportional alternating voltage is induced in coil, this voltage flows to speed probe internal signal treatment circuit and input signal is become digital pulse signal, and detecting box measures the rotary speed of turbo blade according to the frequency change of pulse signal.
The method of detecting box 8 to each sensor signal process is as follows:
The measured value that the utility model is got by each sensor and standard value compare, it is qualified which parameter testing system automatic decision goes out, which is defective, for which underproof parameter, system is from the fault experts database system of data storage center, retrieve corresponding failure cause out, be shown to maintainer one by one, get rid of concrete failure cause by maintainer.
Detecting box 8 can also be used for the control circuit board detecting smoking car; Concrete detection method is as follows:
Each sensor be connected in detecting box is all connected to the corresponding position of smoking car by step 1. respectively, opens the detection system on detecting box, in detection system, open function of being fuming;
Step 2 is after function is fuming in unlatching, detection system is according to the flow process of being normally fuming, simulate such flow process, each working node in systems in which send corresponding simulating signal to the control panel on smoking car, detection control plate is when there being working signal of being normally fuming to input, perform the working condition on each Controlling vertex, can inspection control panel carry out work according to standard, and show on detecting box;
If step 3 has certain Controlling vertex of control panel to break down, then shift to an earlier date comparison in the good failure message storehouse of typing in detection system and find out corresponding failure cause, and be shown to repairman, carried out next step concrete diagnosis by repairman.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
