Abstract

The invention, which relates to the technical field of the automotive measurement apparatus, provides an automotive electronic module measurement device. An industrial control computer is connected with an analog quantity input-output card; the analog quantity input-output card, a high-side output terminal, a low-side output terminal, a programmable resistance board, an automotive electronic universal communication interface module, and a programmable power supply are connected with a to-be-measured sample piece; the to-be-measured sample piece is connected with a programmable load box that is connected with a large-scale switch matrix; the large-scale switch matrix; is connected with a high-precision multimeter; and the high-precision multimeter is connected with the programmable power supply. With the apparatus, measurement of multiple kinds of automotive electronic modules including BCM and SJB can be realized; and the measurement data can be uploaded to a factory information management system. And the management worker or technicist can check production situations of all testing stations in real time; and a history searching function can be provided.

Description

Technical field: [0001] The invention relates to the technical field of automobile measuring devices, in particular to an automobile electronic module (BCM, SJB) measuring device. Background technique: [0002] With the development of the economy, people have higher and higher requirements on the comfort, reliability, energy saving and other aspects of the car, and a large number of electronic control units are used in the car. BCM and SJB, as body control and power distribution control units, are complex electronic devices with multifunctional inputs and outputs. The use environment is very harsh and complex, the product circuit and software are very complex, the peripheral interface is extremely rich, and the manufacturing process is complicated. Strict testing must be carried out before the product goes offline to ensure that the product is free from defects. Test engineers face many challenges when designing and developing suitable test systems. [0003] At present, th...
