Abstract
The invention belongs to the technical field of water detection and particularly relates to a material water detection device. The invention provides the water detection device which has the advantages of low cost, high measuring precision and small volume. The material water detection device comprises six parts including a digital temperature sensor, a water senor, a C/V (Current/Voltage) converter, a single chip microcomputer, a keyboard input and an LCD (Liquid Crystal Display). The digital temperature sensor is connected with an input end of the single chip microcomputer; and an output end of the water sensor is connected with an input end of the C/V converter. An output of the C/V converter is accessed into an A/D (Analogue/Digital) input end of the single chip microcomputer; and an output end of the single chip microcomputer is connected with an input end of the LCD. The keyboard input is accessed into the input end of the single chip microcomputer to control the detection of water in materials.
Description
Technical field
The invention belongs to the water content detection technical field, particularly a kind of material moisture pick-up unit.
Background technology
The water cut of material has very large impact to the quality of material, for the detection of water cut great meaning is arranged.In recent decades, the development of material moisture detection technique is rapid, and traditional detection is by drying means and chemical method, and direct-detection goes out the absolute water content in the material, and accuracy of detection is high, but time-consuming, is unsuitable for online and Site Detection.For the shortcoming of existing conventional art water content detection, invent the moisture content detection device that a kind of cost is low, volume is little, measuring accuracy is high and have great superiority and market potential.
Summary of the invention
For the deficiency that prior art exists, it is low to the invention provides a kind of cost, and measuring accuracy is high, the moisture content detection device that volume is little.
Technical scheme of the present invention is achieved in that this material moisture pick-up unit comprises digital temperature sensor, moisture transducer, and the C/V converter, single-chip microcomputer, keyboard input and LCD show that six parts form.The input end of digital temperature sensor access single-chip microcomputer, the input end of the output terminal access C/V converter of moisture transducer.The A/D input end of C/V converter output access single-chip microcomputer, the input end of single-chip microcomputer output termination LCD display.The input end of keyboard input access single-chip microcomputer, the detection of control material moisture.
This material moisture pick-up unit is that moisture transducer is detected the gained capacitance signal changes A/D voltage input signal in the monolithic Bigpian into by the C/V converter scope, single-chip microcomputer is processed and computing afterwards, in processing procedure, by the real-time measurement to environment temperature, add temperature compensation, to improve measuring accuracy.Afterwards measured material moisture numerical value is shown by LCD display.Can select various water content detection patterns by Keyboard Control, realize the measurement of material moisture.
Advantage of the present invention: this installation cost is low, measuring accuracy is high, volume is little.
Description of drawings
Fig. 1 is structured flowchart of the present invention.
Embodiment
Detailed construction of the present invention is illustrated in conjunction with the embodiments.
This material moisture pick-up unit as shown in Figure 1, moisture transducer adopts capacitance type sensor, digital temperature sensor is selected DS18B20, it is C8051F005 that single-chip microcomputer is chosen model.
This material moisture pick-up unit comprises digital temperature sensor, moisture transducer, and the C/V converter, single-chip microcomputer, keyboard input and LCD show that six parts form.The input end of digital temperature sensor access single-chip microcomputer, the input end of the output terminal access C/V converter of moisture transducer.The A/D input end of C/V converter output access single-chip microcomputer, the input end of single-chip microcomputer output termination LCD display.The input end of keyboard input access single-chip microcomputer, the detection of control material moisture.
This material moisture pick-up unit is that moisture transducer is detected the gained capacitance signal changes A/D voltage input signal in the monolithic Bigpian into by the C/V converter scope, single-chip microcomputer is processed and computing afterwards, in processing procedure, by the real-time measurement to environment temperature, add temperature compensation, to improve measuring accuracy.Afterwards measured material moisture numerical value is shown by LCD display.Can select various water content detection patterns by Keyboard Control, realize the measurement of material moisture.
