Problems solved by technology

Existing method of switch value acquisition can only collect a single type of switch value. When there are multiple types of switch value signals in the industrial field, only by redesigning the system can multiple types of switch value signals be selected. Therefore, the existing switch value The collection method does not have the function of collecting multiple types of switch signal selection

Abstract

The embodiment of the invention discloses a method for collecting a switching value signal by a data acquisition transmitter. based on the data acquisition transmitter, a data acquisition transmitter comprises a switching value signal input interface, an optocoupler, a data buffer, a processor, a dialing code switch and multiple current limiting resistors, wherein the optocoupler comprises a light-emitting diode and a phototriode, and the multiple current limiting resistors are all connected with the light-emitting diode, and the phototriode is connected with the data buffer. The method comprises the following steps: switching the multiple current limiting resistors by utilizing the dialing code switch; collecting an input switching value signal by utilizing the switching value signal input interface; and converting the collected switching value signal to a logic high low level by utilizing the optocoupler. In the embodiment of the invention, the current limiting resistors corresponding to multi-class switching value signals are selected through the dialing code switch; therefore, a system is not needed to redesign, only the same optical coupler is needed to use so as to flexibly achieve acquisition of the multi-class switching value signals.

Description

technical field [0001] The present invention relates to the field of signal acquisition, and more specifically, relates to the acquisition of a switching value signal. Background technique [0002] With the continuous development of science and technology, the requirements for signal acquisition in electronic technology are getting higher and higher, especially for the acquisition of multi-channel signals. Existing method of switch value acquisition can only collect a single type of switch value. When there are multiple types of switch value signals in the industrial field, only by redesigning the system can multiple types of switch value signals be selected. Therefore, the existing switch value The collection method does not have the function of collecting multiple types of switch signal selection. [0003] To sum up, how to provide a switching signal acquisition system and method capable of collecting multiple types of switching signals is an urgent problem to be solved b...
