Electrical control signal output device

Abstract

The invention provides an electrical control signal output device. The electrical control signal output device provided by the embodiment of the invention comprises a cabinet body, a main control board, a power conversion module and a signal generation module are arranged in the cabinet body, an interaction panel is arranged on the cabinet body, and a control system is respectively connected with the power conversion module, the signal generation module and the interaction panel; the power interface of the main control board is used for being connected with an external driving power supply, and the power conversion module and the signal generation module are each provided with at least one output end; the interaction panel is used for acquiring setting parameters input by a user, so that the main control board configures the power conversion module and / or the signal generation module according to the setting parameters, and signals matched with parameter configuration are output at the corresponding output ends. According to the electrical control signal output device provided by the invention, a working power supply signal, a switching value signal, an analog quantity signal and input signals of various measurement and control sensor signals required by a given locomotive control system can be realized.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an electrical control signal output device. Background technique [0002] With the continuous maturity of power electronic technology and microcomputer control technology, technologies such as SCR motor speed regulation and closed-loop measurement and control based on a large number of sensors have been widely used in the railway locomotive industry. [0003] At present, the off-board performance testing tests for the locomotive microcomputer control system, driving safety control system, locomotive on-board safety protection system (6A system), and retrofitting system need to be tested based on the actual operating environment of the locomotive, and only part of the functions can be completed. test. For example, the realization of the measurement and control sensor signal during the test usually uses the pressure sensor transmission signal created by the actual air syst...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the method of testing based on the actual operating environment of the locomotive cannot meet the requirements of a comprehensive test, and because of the instability of the actual operating environment of the locomotive, it is difficult to meet the requirements of the actual test.
