Method for realizing general digital quantity regulation

Abstract

The invention relates to a realization method of general digital signal conditioning. For the output signal conditioning of general signals, a two-way optical control isolation MOS relay is used to form a two-way channel for the flow direction of external signals; for the access of multi-voltage signals, a multi-selection One jumper block realizes multi-voltage access conditioning; for multi-form loads, single-point bidirectional high-current channels are used to solve single-point signal conditioning; dual-point differential output is used to solve differential signal conditioning. For the input signal conditioning in the general signal, the two-way optocoupler is connected in series, and the configuration method of connecting different resistance resistors through an external multi-choice jumper block is used to realize the input signal conditioning of the single-point signal with different voltages and different current directions; The diode and the bidirectional optocoupler are connected in series and the conditioning of the dual-point input signal is realized through a configuration method in which two continuous channels are associated. The invention adopts simple components, low material cost, small volume, simple operation and wide adaptability.

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 designers of imitation test and measurement 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.
