Abstract

The invention discloses a signal generating platform for automobile instrument detection and a signal generating method of the signal generating platform and belongs to the field of electrics. The invention aims to solve the problems that several generating devices need to be used simultaneously, and are complicated in wiring and not portable when all signals are checked simultaneously by a traditional signal generating device. A power module of the signal generating platform disclosed by the invention is used for supplying electricity for a core controller, a displayer and a keyboard; the keyboard is used for inputting a command signal to the core controller; the core controller is used for controlling the display of the displayer; the oil mass resistance signal output end of the core controller is connected with a fuel gauge signal input end; a gas quantity resistance signal output end is connected with a gas meter signal input end; a switching value signal output end is connected with a switching value signal input end; a gas pressure analog voltage signal output end is connected with a gas-pressure meter signal input end; a storage battery analog voltage output end is connected with a storage battery voltage signal input end; a revolution speed pulse signal output end is connected with a revolution meter signal input end; a vehicle speed pulse signal output end is connected with a speedometer signal input end. The signal generating platform and the signal generating method of the signal generating platform are used for the detection of automobile instrument information.

Description

technical field [0001] The invention relates to a signal generation platform of an automobile electronic control unit and a method for generating signals thereof, belonging to the field of electricity. Background technique [0002] For the finished automotive instrument, the signals processed on it include gas gauge, fuel gauge, speedometer, tachometer, barometer, etc. And these signals can be divided into resistance signal, analog voltage signal, switch signal and pulse signal according to the type. Before the meter leaves the factory, it is necessary to verify all the signals, that is, to input the corresponding resistance signal or other signals to check whether the meter has the correct indication reading. Some existing signal generators can only output some of the signals. Simultaneous inspection of all signals requires several generators to be used at the same time. The connection is cumbersome and inconvenient to use; and the application of these inspection devices i...
