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.

Embodiment Construction

[0015] 1. The method for realizing general conditioning of digital output signals comprises the following steps:

[0016] 1. Circuit structure

[0017] Its circuit diagram is shown in Fig. 1. According to the analysis of various types of digital output signals, combined with the development of device technology, the digital output signal conditioning circuit of the present invention consists of the following parts:

[0018] A bidirectional optical control isolation MOS relay is set on the conditioning board, and the output signal from the control system is isolated from the output signal of the conditioning circuit through the bidirectional optical control isolation MOS relay. The positive input terminal (+) of the bidirectional optical control isolation MOS relay There is a resistor R1 connected to the 5V power supply of the input signal, and the negative input terminal (-) of the bidirectional optical control isolation MOS relay is connected to the TTL signal output from th...

Abstract

This invention discloses a conditioning method for digital signals (DS).It includes the following aspects: adopt isolation MOS relay to condition export signal; adopt jumper clot to condition multi-voltage signal; adopt large current channel to condition single spot signal; adopt two-point difference export to condition difference signal; adopt serial light coupling and fabric method to condition export signal; adopt diode, light coupling and fabric method to condition two spot input signal. The advantages are low cost, small volume, easy to operate.

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...
