Description
Technical Field
The utility model relates to a signal transfer box, in particular to but signal transfer box of automatic/manual simulation trouble.
Background
In the development process of the electric control system, testing and verification are indispensable and extremely important links, and in order to realize effective testing, corresponding testing and diagnosis environments need to be established. Under the normal condition, a signal transfer box (Break-out box) is used for testing or experiments with an automobile controller, and is generally connected in series between the automobile controller and a wire harness for a tester to intercept signals or artificially simulate faults. The connection mode is that the tested controller is connected to the hardware in the ring test environment, the signal is led out from the corresponding channel of the front panel, the observation, the recording and the measurement are convenient, and the on-off test of the signal, the ground test, the short circuit test of the power supply and the like can be carried out manually.
The traditional signal transfer box (Break-out box) needs to carry out on-off test on signals in a manual mode, and needs to carry out manual operation on each path by field operation testers when the signals are short-circuited to the ground and the power supply, wherein part of signal test requirements require repeated test for dozens of times, and part of signal test requirements require fixed test sequences. The tedious manual operation often causes that the operation tester does not execute the test sequence according to the requirement or the test does not reach the test requirement times.
The traditional signal transfer box (Break-out box) is connected between the automobile controller and the wiring harness in series, so that the automobile wiring harness can be conveniently detected, but other measuring equipment is still required to be connected. In the process of testing the open circuit and the open circuit, and testing the short circuit of the ground and the power supply, because no real-time detection signal exists, if an abnormal signal occurs in the testing process, the on-site judgment cannot be carried out, and the on-site judgment can only be carried out by testing and recurring analysis again after the measurement equipment is accessed.
The single-path maximum bearing capacity of a traditional signal transfer box (Break-out box) is not more than 10A, along with the development of automobile controllers, more and more automobile controllers need controller motors, the instantaneous power of the motors is large, and the single-path maximum bearing capacity 10A cannot meet the requirement.
SUMMERY OF THE UTILITY MODEL
In view of the technical problem who exists among the background art, the utility model aims at providing a but signal transfer box of automatic/manual simulation trouble, can carry out automatic fault test and real time monitoring.
In order to solve the technical problem, the utility model discloses a following technical scheme: the signal transfer box capable of automatically/manually simulating the fault is characterized by comprising a signal transfer interface and a PXI platform, wherein an FIU board card and a signal acquisition card are arranged in the PXI platform, the FIU board card is used for carrying out fault injection automatic testing after the signal transfer interface is connected with a signal, and the signal acquisition card is used for carrying out real-time monitoring.
The FIU integrated circuit board is equipped with 8 ways FIU integrated circuit boards and 40 ways FIU integrated circuit boards, 8 ways FIU integrated circuit boards with be used for inserting 8 way signal switching interface connections of pencil, 40 ways FIU integrated circuit boards with be used for inserting 32 way signal switching interface connections of pencil.
The utility model has the advantages that: a PXI platform is arranged in a traditional signal junction box, fault injection automatic testing is carried out through an FIU board card, real-time monitoring is carried out through a signal acquisition card, and therefore automation of a signal transfer box is achieved.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to the drawings, a signal transfer box capable of simulating faults automatically/manually comprises a signal transfer interface 1 and a PXI platform 2, wherein one main advantage of the PXI platform is integrated timing and synchronization functions. An FIU (fault injection) board card and a signal acquisition card 4 are arranged in the PXI platform 2, the FIU is a common fault bus topology, and each channel can be opened and short-circuited for one or more faults. The signal switching interface 1 is connected with a signal, then the FIU board card is used for carrying out fault injection automatic testing, the signal acquisition card 4 is used for carrying out real-time monitoring, in the embodiment, 80 paths of voltage acquisition board cards are used for carrying out signal monitoring, the current sensor is used for acquiring the current of the wire harness, and the voltage of the wire harness is acquired in a voltage division mode.
The FIU integrated circuit board is equipped with 8 way FIU integrated circuit boards 31 and 40 way FIU integrated circuit boards 32, and the biggest support current of 8 way FIU integrated circuit boards is 200A, and the biggest support current of 40 way FIU integrated circuit boards is 5A, 8 way FIU integrated circuit boards with be used for inserting 8 way signal switching interface connection of pencil 41, 40 way FIU integrated circuit boards with be used for inserting 32 way signal switching interface connection of pencil 42. Considering the price problem of the FIU board card, the maximum load current supported by the 8-path bundle is 40A, so that the FIU board card is corresponding to the 8-path FIU board card; because the maximum load current supported by the 32-path bundle is 5A, 40 paths of FIU board cards correspond to the maximum load current, the design makes full use of the characteristic that the FIU can bear large load current, and the problem of single-path maximum bearing capacity of the traditional signal transfer box is solved.
