Detailed Description
Fig. 1 and 2 schematically illustrate a signal transfer device 100 provided according to an embodiment of the present invention from different viewing angles, respectively. As shown in fig. 1, the signal adapter 100 includes an adapter housing 110 and an adapter 120, and the input signal and the output signal are simultaneously transmitted to different components through the adapter 120, so as to improve the versatility and the convenience of the signal adapter.
Specifically, a plurality of pairs of test ports 111a and 111b and relay device interfaces 112 corresponding to the test ports 111a and 111b are arranged on the surface of the relay box body 110. For ease of docking use, the interface of the transition device 112 may be disposed on a surface adjacent to the test ports 111a, 111 b. More specifically, the translator interface 112 includes both an input and an output of the signal translator 100, and has a plurality of pins disposed thereon. Each pin corresponds to a respective test port 111a, 111 b.
The signal adapter further includes an adapter 120 interconnected to the adapter interface 112, one end of which is connected to the input and output of the signal adapter 100 via the adapter interface 112. Here, it can be seen that the adaptor connector 120 further includes two sets of adaptor harnesses 121a, 121b at the other end, and the part to be tested 200 and the control part 300 are respectively connected to the input end and the output end of the signal adaptor device 100 through the two sets of adaptor harnesses 121a, 121b, so as to respectively transmit the input signal and the output signal between the part to be tested 200, the control part 300 and the adaptor box 110.
Fig. 1 and 2 show further detail variants of an embodiment of the invention.
For example, multiple sets of test ports 111a, 111b are provided at the surface of the pod 110, each set of test ports 111a, 111b in turn comprising multiple pairs of test ports. Accordingly, a plurality of adaptor interfaces 112 are provided at the other surface of the adaptor box body 110, wherein each adaptor interface 112 corresponds to one set of test ports 111a, 111 b. Here, 4 sets of test ports 111a, 111b and 4 translator interfaces 112 are exemplarily shown, and each set of test ports 111a, 111b in turn comprises 40 pairs of test ports. This number of test ports 111a, 111b and translator interface 112 is already able to meet the signal input output requirements of most external devices.
In this case, the signal transfer device 100 may include 4 transfer plugs 120 at the maximum. Correspondingly, the number of signal paths of each adapting connector 120 is less than or equal to 40. Alternatively, the adaptor connector 120 and the adaptor interface 112 may be connected by a pin connection.
Meanwhile, the two sets of adaptor harnesses 121a and 121b of the adaptor connector 120 are respectively connected to the vehicle electrical components and the control module. The lengths of the relay harnesses 121a and 121b can be arbitrarily selected depending on the use. This enables more convenient signal transmission between the vehicle electrical components and the control module.
Additionally, the signal relay device may also include a switch 113. As can be seen in fig. 1 and 2, each switch 113 is arranged between a respective pair of test ports 111a, 111b and corresponds one-to-one to each pair of test ports 111a, 111 b. By toggling the switch 113, the switch is brought into contact with different switch contacts in the transfer cabinet, so that each pair of test ports 111a, 111b is switched into different test loops accordingly. In an exemplary embodiment, the switch 113 is operable to switch in two different test loops, open and closed.
In addition, a fault diagnosis system applying the signal switching device in the previous embodiment is also provided. Fig. 3 schematically illustrates the role of the signal relay device 100 in the fault diagnosis of electrical components of a vehicle. The signal switching device 100 is used for providing a switching interface between the to-be-tested part 200 and the control part 300, and realizing connection matching between different electrical components. Compared with the mode that the part to be tested 200 and the control part 300 are directly connected with each other, the signal transfer box can provide matching universality, so that signal transmission and signal output between the part to be tested 200 and the control part 300 are more conveniently and efficiently realized.
The application of signal relay device 100 in different test loops is outlined below by several examples.
As shown in fig. 4, when a signal extraction is required, multimeter 600 is interposed between test ports 111a, 111b of signal relay apparatus 100 corresponding to the signal to be extracted and the negative electrode of battery 400, so that the loop voltage and the loop resistance are directly measured. And when an open circuit fault is simulated, switch 113 is toggled directly into the open switch contact inside pod 110.
As shown in fig. 5, when the analog-to-voltage short circuit occurs, the test lamp 700 is connected between the test ports 111a and 111b of the signal relay device 100 corresponding to the signal to be analog and the positive electrode of the secondary battery 400.
As shown in fig. 6, when a short circuit to ground is simulated, a jumper wire 800 having a fuse of a certain capacity is connected between the test ports 111a, 111b of the signal relay device 100 corresponding to the signal to be simulated and the negative electrode of the battery 400. The electrical components of the vehicle may show corresponding fault symptoms according to the types of the faults, and detailed fault information of the test circuit, such as fault diagnosis codes, fault diagnosis information parameters and the like, may be read by fault diagnosis software connected to the DLC port 500 of the vehicle. In conclusion, the signal switching device greatly reduces the difficulty of fault diagnosis and test of the vehicle electrical components, and meanwhile, the diagnosis efficiency and accuracy are improved.
Fig. 4, 5 and 6 illustrate only by way of example how a fault simulation of an electrical component of a vehicle is carried out using a signal transfer device according to the invention, but this should not be understood in a limiting manner. It is fully feasible for a person skilled in the art to use the signal transfer device according to the invention for other fault simulation and diagnosis of electrical components.
Thus, a fault diagnosis system for vehicle electrical components can implement many other types of fault simulation and diagnosis using a signal switching device according to the present invention. Compared with the fault diagnosis system known in the prior art, the fault diagnosis system for the vehicle electrical component and provided with the signal switching device considers the particularity and complexity of the wiring harness connection of the vehicle electrical component, so that the fault simulation and diagnosis of the vehicle electrical component can be realized more accurately, conveniently and efficiently.
