Description

Be applied to multi-functional fault setting ware of whole car teaching examination

Technical Field

The utility model relates to a fault setting ware technical field is used in the teaching, concretely relates to be applied to multi-functional fault setting ware of whole car teaching examination.

Background

The conventional fault setting device for teaching has the defects of single fault setting type and complex structure, brings the defects of complex use flow, complex maintenance and the like to daily teaching while solving teaching examination, and is difficult to meet the examination requirements of multiple points, dispersion and concealment in the whole vehicle examination teaching due to the complex and huge system structure.

Traditional ship type switch formula trouble sets up switch, because of its fault type is single (open circuit), receive oxidation factors such as ambient humidity for a long time and influence and lead to switch contact failure etc. lead to no reason to increase unclear trouble and influence normal teaching in the use and use, so this type trouble sets up switch and is eliminated by the market gradually.

2. The wireless or touch screen single-chip microcomputer type fault assessment system has the phenomena of single fault type (open circuit), unstable system communication short boards, incapability of normally performing teaching or terminating assessment due to assessment system faults in the using process and the like. In daily teaching, teachers also need to spend a great deal of energy and time to study and operate the fault setting and checking system.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the utility model discloses during multi-functional trouble setting ware was applied to whole car and the real standard platform teaching examination of teaching, had stable performance, integrated degree height, it is easy and simple to handle, can realize a plurality of troubles simultaneously at same trouble node. By adopting the module design, the faults can be dispersedly, concealably and multipoint set according to the requirements of the whole vehicle system and the size of the vehicle space, and the fault types and fault points of the real vehicle can be more truly simulated. The problem of teaching effect and emulation are poor because the trouble setter operation is complicated, the trouble is single in the daily teaching examination is effectively solved.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model discloses after multi-functional trouble setting device implanted whole car and real standard equipment circuit, adopt mechanical switch formula structure to change the circuit trend through adjustment knob position change "change over switch" and realize fault simulation and trouble examination etc.. A plurality of modules can be flexibly combined into a module to be applied to the whole vehicle or practical training equipment to realize the classification and arrangement of subsystems, so that the daily teaching management is convenient.

Compared with the prior art, the utility model discloses the technological effect who possesses does:

the utility model discloses during multi-functional trouble setting ware was applied to whole car and the real standard platform teaching examination of teaching, had stable performance, integrated degree height, easy and simple to handle, can realize simultaneously that circuit break, short circuit (adjust well/to the burden) virtual connect, the 5 troubles of the 4 kinds of occasional accidents are sent out at same trouble node. The multifunctional fault setting device adopts a modular design, can independently arrange single-cell modules and can combine a plurality of modules into an integrated module according to actual needs, thereby reducing the defects of complicated wiring and the like. For example, 12 nodes of the 12-way module can be simultaneously failed, each failure does not interfere with each other, and at most, 48 failures in 4 classes can be set. A single fault point can bear the maximum current of 5A, and virtual connection can be set to have different virtual connection analog resistances of 5 omega, 10 omega, 50 omega, 100 omega, 500 omega and the like according to the actual fault condition so as to meet the current load requirements of most sensors, actuators, control power supplies and the like. The combination of the special connecting wire harness can realize the sharing of the fault setting plate, thereby avoiding the defects of complexity of a large number of leads and space limitation of the fault setting terminal.

The multifunctional fault setting device is used for arranging and hiding faults in different positions of a vehicle body in the distribution of all systems of the whole vehicle, and has the advantages of high integration degree, strong simulation, wide fault range, instant recovery of the faults, no influence of system instability and the like. The circuit fault detection device can be used for setting various circuit faults between circuit system intervals, and can also be used for combining simulation settings of components, fuses and the like with different difficulties and different types of faults, thereby meeting the requirements of daily teaching and various-grade assessment of a competition.

The utility model discloses a main defect lies in: although the multifunctional fault setter can be applied to teaching and examination of a whole vehicle and a teaching and training platform and has the advantages of stable performance, rich fault types, high module integration degree, simplicity and convenience in operation and the like, due to the fact that the current capacity and the load of the switch and the module are limited, a line section where a set fault point is located cannot be a large-current load (5A), and the fact that the multifunctional fault setter cannot set a line fault with the current larger than 5A is also limited.
