Example Embodiment

[0028] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0029] figure 1 Shows a schematic structural diagram of an automotive electronic control unit radiation anti-interference test monitoring system provided by an embodiment of the present invention. The test electromagnetic signal is transmitted through the transmitting antenna 110 in the EMC darkroom 105, and the electronic control unit 108 under test is radiated through space radiation , In order to complete the radiation anti-interference test of the electronic control unit 108 to be tested.

[0030] The control host 101 located outside the EMC darkroom 105 serves as a host computer so that the user can perform overall control of the system, while receiving and recording the output signal of the electronic control unit 108 to be tested and displaying it to the user. The control host 101 respectively sends a first control signal and a second control signal to th...

Abstract

The invention discloses a radiation anti-interference test monitor system for an automotive electronic control unit. The system comprises a transmitting antenna and an electronic control unit to be detected, which are arranged within an EMC (electro magnetic compatibility) darkroom, and signal imitation equipment, a protocol signal receiving and dispatching module and a control master machine, which are arranged outside the EMC darkroom,. The control master machine controls the protocol signal receiving and dispatching module and the signal imitation equipment to generate protocol input signals and non-protocol input signals required for imitating the working condition of a whole automobile, the protocol input signals and the non-protocol input signals are transmitted to the electronic control unit to be detected through an optical fiber, and an output signal generated by the electronic control unit to be detected is timely monitored, so that the aim of test can be achieved. The signal transmission among the signal imitation equipment, the protocol signal receiving and dispatching module and the electronic control unit to be detected is realized by the optical fiber, so that the influence of the veracity of a test result caused by electromagnetic interference when the signal is transmitted can be avoided; and therefore, a real test result can be obtained.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a radiation anti-interference testing and monitoring system for electronic control units of automobiles. Background technique [0002] With the increasing number of electronic control units on the vehicle, the electromagnetic environment in which the vehicle is located is becoming increasingly complex. On the one hand, the electronic control unit needs to coexist with the radio frequency transmitter. On the other hand, the vehicle may also enter the strong electromagnetic field area generated by some external transmitters, such as the electromagnetic field area with an intensity of tens or even hundreds of volts per meter. Electromagnetic interference from electronic control units including semiconductor logic devices. Therefore, before the vehicle leaves the factory, it needs to do a specific Electro Magnetic Compatibility (EMC) test to ensure that the electronic control un...
