Signal detection and control method based on serial communication

Abstract

The invention discloses a signal detection and control method based on serial communication. The signal detection and control method comprises an upper computer, a sensor, a sensor interface and a control module; the sensor is connected with the control module through the sensor interface to form a sampling circuit, and the sampling circuit receives data measured and collected by the sensor and sends the data to the control module for processing; the control module classifies and filters the received sensor data and then sends the sensor data to the upper computer; when the upper computer serves as an output end, the upper computer receives the digital quantity data, carries out calibration calculation, and displays an actual numerical value and an image curve in real time; when the upper computer serves as an input end, after an instruction of an operator is received, the instruction is sent to the control module through the RS232, and after the control module receives the instruction, control over specific external equipment is completed through the output port. According to the invention, numerical value reading and calibration of sensor information can be realized, intercommunication of various kinds of sensor information is realized, the cost is low, the expansibility is strong, and the method is suitable for various occasions.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a signal detection and control method based on serial communication. Background technique [0002] In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process, so that the equipment can work in a normal or optimal state, and the product can achieve the best quality. Sensors have already penetrated into a wide range of fields such as industrial production, space development, ocean exploration, environmental protection, resource investigation, medical diagnosis, bioengineering, and even cultural relic protection. It is no exaggeration to say that from the vast space, to the vast ocean, to various complex engineering systems, almost every modern project is inseparable from various sensors. [0003] However, due to the wide variety of sensors, the internal integrated num...

Problems solved by technology

[0003] However, due to the wide variety of sensors, the internal integrated numerical display function responds slowly, which is not suitable for occasions that require high real-time numerical values. At the same time, each sensor is independent of each other, so it is difficult to realize the intercommunication of sensor information.
