TTE network transmission delay test system and method

The invention discloses a TTE network transmission delay test system. The system comprises a to-be-tested TTE network, test execution equipment and test management equipment; the test management equipment is used for responding to a user test operation and sending a time delay test instruction to the test execution equipment; and the test execution equipment is used for acquiring sending signal information and receiving signal information in the TTE network to be tested in response to the time delay test instruction, and determining the transmission time delay of the TTE network according to the sending signal information and the receiving signal information. Visibly, the transmission delay of the TTE network is analyzed in a mode of combining board card trigger acquisition and software data analysis in the test execution equipment, that is, time data acquisition and analysis are performed on the TTE network at a board card level, the risk of influencing the data in the TTE network at a protocol layer is reduced, and the use of third-party test equipment is avoided, therefore, the complexity of TTE network testing is reduced, and the risk that TTE network transmission information is tampered and the correctness of transmission data is affected is also reduced.

Deposited carbon regeneration and thermal fatigue simulation testing system of diesel fuel particulate trap

The invention provides a deposited carbon regeneration and thermal fatigue simulation testing system of a diesel fuel particulate trap. The deposited carbon regeneration and thermal fatigue simulation testing system comprises a diesel fuel particulate filter, a differential pressure transducer, a burner simulation device, and a controller. The gas inlet of the diesel fuel particulate filter is connected with the gas outlet of the burner simulation device, and the two probes of the differential pressure transducer are respectively connected with the gas inlet opening and the gas outlet opening of the diesel fuel particulate filter, and in addition, the differential pressure sensor and the burner simulation device are connected with the controller. The controller is used to control the flow and/or the temperature of the gas outlet of the burner simulation device according to preset configuration information or external input, and is used to acquire the deposited carbon regeneration characteristic parameter, and/or the thermal fatigue characteristic parameter, and/or the operation parameter of the diesel fuel particulate filter according to differential pressure signals received by the differential pressure transducer. A user testing technology is simplified, and by aiming at DPF of development of different engine models, testing curves and testing data packages matched with the different models are formed, and are used for development, researches, and subsequent tests.
