Abstract
The utility model discloses automobile automatic gearbox electric control system fault teaching equipment, which comprises a signal switching device, a fault setting device and a display device, wherein the fault setting device is connected with an OBD port of an automobile through the signal switching device; and the display device is connected with the fault setting device. The teaching equipment disclosed by the utility model can set faults in a centralized manner, ensures the accuracy and the concealment of fault setting, improves the efficiency of teaching and the assessment process greatly, and ensures the preciseness of the assessment process.
Description
Technical field
The utility model relates to a kind of teaching equipment, is specifically related to a kind of teaching equipment that detects and get rid of at the automatic gearbox electric-controlled system fault.
Background technology
The automatic speed-variator electric control system fault is that automobile is the most common, one of most important fault, and its failure cause is various, and the exclusion process complexity.In order to improve teaching efficiency, a large amount of automatic speed-variator electric control system teaching equipments that use in teaching process.But because automatic speed-variator electric control system fault components and parts are numerous, have a very wide distribution, the subelement position is hidden.The real training class hour of present School of High Profession Technology is limited, and it is low that traditional teaching equipment fault arranges efficient, limited the expansion of the content of courses.
The equipment of conventional teaching simultaneously directly arranges fault at element, and the disguise that fault arranges is not high.The student can adopt informal approach to find failure cause, examination process preciseness deficiency.
Summary of the invention
The purpose of this utility model is the defective that exists in the prior art in order to solve, and a kind of efficient height, rigorous the detecting and the teaching equipment of getting rid of at the automatic gearbox electric-controlled system fault of examination are provided.
In order to achieve the above object, the utility model provides a kind of automatic gearbox electric-controlled system fault teaching equipment, comprises signal adapting device, fault setting device and display device; The fault setting device links to each other with the OBD port of automobile by signal adapting device; Display device links to each other with the fault setting device.
Further improvement of the utility model is: this teaching equipment also comprises demoder, and this demoder links to each other with the OBD port of automobile.
Wherein, the fault element signal of fault setting device setting comprises idle signal, tach signal, air throttle control signal, neutral starting switch signal, overspeed switch signal, 2 vehicle speed sensor signals and 4 solenoid valve signals.
The utility model has following advantage compared to existing technology: the utility model utilizes the fault setting device, simulate the various true fault signals of the automatic gearbox electric-control system of summarizing by virtual instrument technique, concentrate fault is set, accuracy and disguise that fault arranges have been guaranteed, improve the efficient of teaching and examination process greatly, guaranteed the preciseness of examination process.Can show various troubleshooting of faults processes by display device simultaneously, as teaching reference, improve teaching efficiency.And the student can carry out real training by instrumentation instrument such as demoders, reaches the consistent of operating process and practical work process.
Description of drawings
Fig. 1 is the structural representation of the utility model automatic gearbox electric-controlled system fault teaching equipment;
Fig. 2 is for utilizing teaching process process flow diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model automatic gearbox electric-controlled system fault teaching equipment is elaborated; all changes of doing according to technical solutions of the utility model; when the function that produces does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model automatic gearbox electric-controlled system fault teaching equipment comprises signal adapting device, fault setting device and display device, being used for the fault element signal of fault setting device setting of simulated automotive automatic speed-variator electric control system fault is transferred to automobile OBD port by signal adapting device, do not destroy component body, conversion is from the relevant element signal of the automatic speed-variator electric control system fault of automobile.
According to the analysis to the content of courses of automatic speed-variator electric control system fault, summarizing goes out the idling device, engine speed sensor, air throttle control device, neutral starting switch, overspeed switch, 2 vehicle speed sensor, 4 fault elements such as solenoid valve.The working signal of these elements is transferred to automobile OBD port by signal adapting device, and the student can connect the OBD port by instrumentation instrument such as demoders and carry out real training, guarantees that operating process is consistent with practical work process.
Phenomenon of the failure, fault detection method and troubleshooting methodology etc. with these elements are organized into data simultaneously, make video, when the fault setting device arranges corresponding failure, demonstrate fault in display device and get rid of video, reference as the student learns and examines has improved teaching efficiency.
In conjunction with the utility model fault of utilizing shown in Figure 2 the process flow diagram flow chart that teaching equipment is imparted knowledge to students is set.Wherein, the fault design system of fault setting device is based on Virtual Instrument Development.Be example with a certain fault teaching cases now, explain that fault arranges principle.When I gearshift solenoid valve open circuit fault, phenomenon of the failure is: when automobile travelled with forward gear, unexpected downshift phenomenon appearred in automatic transmission under the situation that throttle remains unchanged, and downshift rear engine rotating speed raises unusually, produced gearshift and impacted.Use demoder Read fault sign indicating number, the diagnostic trouble code content is that I gearshift solenoid valve opens circuit or short circuit.The I gearshift solenoid valve signal that transfers out by fault setting device signal adapting device is set to open circuit or short circuit, just can set out this fault quickly and accurately and imparts knowledge to students.With this principle, set out the fault of other element.
The utility model summarizing the various faults of automatic gearbox electric-control system, and utilize virtual instrument technique to simulate true fault-signal, make the fault setting device, concentrate fault is set, accuracy and disguise that fault arranges have been guaranteed, improve the efficient of teaching and examination process greatly, guaranteed the preciseness of examination process.By making screen, display device can show various troubleshooting of faults processes, as teaching reference, has improved teaching efficiency.The student can carry out real training by instrumentation instrument such as demoders, has guaranteed the consistance of operating process and practical work process.
