Before the technical solutions of the present application are introduced, it is necessary to explain the background of the invention of the present application.

It is common in the related art that various electrical switches of an automobile need to detect the energization performance of each switch in the production process of automobile accessories, and the switches can be used by loading on a car if qualified.

Based on the above-mentioned difficulties, the inventor proposes a detection apparatus for electrical performance detection, when detecting the electrical performance of an electrical component of an automobile, the inventor only needs to access the component to be detected to the I/O interface 60, and simultaneously edits a computer detection flow through a visual interface according to a required detection item, selects more than one of an access detection channel, a voltage detection channel 54, a resistance detection channel 51 and an on-off detection channel 52, the data acquisition card 40 acquires electrical performance data of the component to be detected, analyzes the qualified condition of the electrical performance of the component to be detected through a preset tool carried on the computer 30, and avoids unqualified components flowing out due to detection standard difference, personnel judgment and the like. The manufacturing of special detection equipment is reduced, and the equipment purchasing cost is greatly reduced. Therefore, the invention is created.

Referring to fig. 1, the present application provides a detection apparatus for electrical property detection, which includes a display screen 20, a computer 30 and a data acquisition card 40 electrically connected in sequence, where the data acquisition card 40 is electrically connected to an I/O interface 60, a current detection channel 53, a voltage detection channel 54, a resistance detection channel 51 and an on-off detection channel 52.

It should be understood that, when the electrical performance of the device under test is detected, one end of the device under test is connected to the I/O interface 60, and the other end of the device under test is connected to any one of the current detection channel 53, the voltage detection channel 54, the resistance detection channel 51 and the on-off detection channel 52, according to the required detection items.

Specifically, when the current needs to be detected, one end of the device to be detected is connected to the I/O interface 60, and the other ends are included in the current detection channel 53; when voltage detection is required, one end of the DUT is connected to the I/O interface 60, and the other end is included in the voltage detection channel 54, and so on.

Due to the arrangement of the current detection channel 53, the voltage detection channel 54, the resistance detection channel 51 and the on-off detection channel 52, different numbers of modules with different detection ranges and detection precision can be selected to adapt to different requirements.

It should be noted that the current detection channel 53, the voltage detection channel 54, the resistance detection channel 51 and the on-off detection channel 52 are purely physical hardware, such as a circuit or a chip, and can be obtained in a known manner.

The I/O interface 60, described above, may be configured to adapt access such as, but not limited to, special circuit signals, LIN signals, CAN signals, and the like.

Relevant software tools can be loaded on the computer 30, threshold value judgment according to detection data can be automatically realized, the detection process is edited and stored for starting at any time, the detection process detects according to the editing process, and the equipment automatically judges whether the data is in the threshold value, so that high universality and convenience of the equipment are realized.

In an exemplary embodiment, a scan channel 55 electrically connected to the data acquisition card 40 may also be provided.

Here, the design considerations for scan channel 55 are: because the number of electrical property combinations of any two terminals is very large, the allowed range of normal electrical property data is manually set, the workload is large, and the error and the leakage are easy to occur, so that the scanning channel 55 is adopted, the comparison workpiece can be detected and stored as a judgment standard value), and the standard for judging whether the comparison workpiece is qualified is the comparison workpiece needing to be qualified. Firstly, terminal scanning detection is carried out to determine that the threshold state is 0 or 1, and the threshold state is stored in a detection program to be used for automatically comparing the detection value of the workpiece to be detected and judging whether the detection value is qualified or not.

In particular, it should be stated that the detecting device according to the present application covers the switches of the electrical equipments of the automobile, such as the switches of the entire system in the cockpit of the automobile, for example, a key start switch, a driving mode switch, a video entertainment switch, a headlight adjusting switch, a light wiper combination switch, a LIN signal switch, a CAN signal switch, etc.

Moreover, other electrical components are contemplated. Although these types of devices under test are addressed, it is only necessary to adaptively adjust relevant parameters of the current detection channel 53, the voltage detection channel 54, the resistance detection channel 51 and the on-off detection channel 52 based on general design capability, that is, the overall configuration and the like thereof are within the scope of the present principles.
