Abstract

The utility model discloses an intelligent fault setting machine, which comprises a touch screen, a programmable controller and at least two relays. The touch screen is electrically connected with the programmable controller, and the programmable controller is electrically connected with each relay; and a control signal output end is arranged on each relay. The intelligent fault setting machine is high in safety, strong in commonality, and extremely convenient in both setting and checking.

Description

Intellectual fault is provided with device

Technical field

The utility model relates to a kind of intellectual fault device is set.

Background technology

For strengthening the intuitive of teaching, adopted various teaching systems (as Automobile teaching board) in part school now, in teaching system, often need the artificial fault that is provided with, and the solution situation of fault is judged student's the degree of understanding according to the student.For now, the fault setting adopts mechanical mode to realize that there is following deficiency in this mode:

1, the traditional type switch is provided with, and switch contact is ablated, and security performance is low;

2, when fault is provided with, because the equipment working state difference, so the impulse magnitude of power supply is just different, therefore will influence the mechanical type fault is provided with lifetime of system;

3, the setting of mechanical type fault does not have intelligent functions, and inconvenience when fault is set is also inconvenient during examination;

4, for the teaching system of different model, its fault is provided with may be different, do not have versatility and cause existing fault that device is set, and can't apply to various different models widely.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides a kind of intellectual fault that device is set, and the utility model is safe, highly versatile, and setting and examination are all very convenient.

Its technical scheme is as follows:

A kind of intellectual fault is provided with device, comprises touch-screen, Programmable Logic Controller, at least two relays, and touch-screen and Programmable Logic Controller are electrically connected, and Programmable Logic Controller and each relay are electrically connected, and are equipped with control signal output ends on each relay.

In the utility model, can intuitively instruction be imported by touch-screen, and can the result be exported to the user, use more directly perceived by touch-screen; In Programmable Logic Controller, can intelligence various faults are set in advance, receive the instruction of touch-screen when Programmable Logic Controller after, control the break-make of corresponding relay, thereby produce corresponding fault, the utility model can avoid the traditional type switch that the potential safety hazard of being brought is set, and fault setting and examination are all very convenient; Also in the teaching system applicable to different size and model, versatility is stronger for the utility model.

The technical scheme of the further refinement of aforementioned techniques scheme can be:

This is provided with device and includes mains electricity input end and light current input end, and mains electricity input end and described touch-screen are electrically connected, and light current input end and described Programmable Logic Controller are electrically connected.

On described Programmable Logic Controller, also be provided with data communication interface.As adopt the USB interface, can realize the data transmission between itself and computing machine or other parts.

In sum, the utility model has the advantages that: fault setting and examination are convenient, and be more directly perceived during use, highly versatile.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:

As shown in Figure 1, a kind of intellectual fault is provided with device, comprises touch-screen 1, Programmable Logic Controller 2, at least two relays 3, and touch-screen 1 is electrically connected with Programmable Logic Controller 2, Programmable Logic Controller 2 is electrically connected with each relay 3, is equipped with control signal output ends 6 on each relay 3.This is provided with device and includes mains electricity input end 4 and light current input end 5, mains electricity input end 4 is electrically connected with described touch-screen 1, light current input end 5 is electrically connected with described Programmable Logic Controller 2, can be by mains electricity input end 4 to the civil power of fault input end input 220V, the light current of device input 12V or 24V can be set to fault by light current input end 5, on Programmable Logic Controller, also be provided with data communication interface 7 (in the present embodiment, adopting the usb data interface).

In the present embodiment, by touch-screen 1 can be intuitively will the instruction input, and can the result be exported to the user by touch-screen 1, use more directly perceived; In Programmable Logic Controller 2, can intelligence various faults are set in advance, receive the instruction of touch-screen 1 when Programmable Logic Controller 2 after, control the break-make of corresponding relay 3, thereby produce corresponding fault and by control signal output ends 6 output; Present embodiment can avoid the traditional type switch that the potential safety hazard of being brought is set, and fault setting and examination are all very convenient, has functions such as fault simulation setting, fault eliminating examination, principle of work simulation teching; By Programmable Logic Controller, can require to set 1-48 trouble spot according to reality, the fault simulation degree is intelligent high, practicality, top grade; Can realize and the docking of computer by the usb data communication interface; Also in the teaching system applicable to different size and model, versatility is stronger for present embodiment.

Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
