Problems solved by technology

[0002] For many years, the general conditioning of I / O signals has troubled the designers of simulation test systems. In terms of implementation methods, the current domestic and foreign platforms provide more complex and bulky
[0003] In addition, these methods are difficult to achieve the purpose of general conditioning, and the signal drive of multi-voltage, multi-flow, and multi-form loads and the reception of multi-voltage, multi-flow, and multi-form source signals cannot be completed simultaneously in a set of designs.
Instead, it is realized by re-soldering the connection and temporarily designing a new circuit board, which is time-consuming, laborious and uneconomical.

Description

technical field [0001] The invention belongs to the technical field of computer application, and in particular relates to a method for realizing general digital I / O signal conditioning. Background technique [0002] For many years, the general conditioning of I / O signals has been perplexing the designers of simulation test systems. In terms of implementation methods, the current domestic and foreign platforms provide more complex and bulky. [0003] In addition, these methods are difficult to achieve the purpose of general conditioning, and the signal driving of multi-voltage, multi-flow, and multi-form loads and the reception of multi-voltage, multi-flow, and multi-form source signals cannot be completed simultaneously in one set of designs. Instead, it is realized by re-soldering the connection and temporarily designing a new circuit board, which is time-consuming, laborious and uneconomical. Contents of the invention [0004] The object of the present invention is to p...
