Brief description
Fig. 1 is overall structure figure, and Fig. 2 is signal processing circuit(4)Schematic diagram, Fig. 3 is Single Chip Microcomputer (SCM) system schematic diagram;Fig. 1- In Fig. 3,1 is infrared transmitting tube, 2 is medicine bottle, 3 is photoelectric sensor, 4 is Signal sampling and processing circuit, 5 is single-chip microcomputer system Unite, 6 is power supply circuits.
Specific embodiment
This utility model is used for detecting the vacuum of vacuum medicine bottle, this device is by infrared transmitting tube (1), medicine bottle(2), photoelectricity Sensor (3), signal processing circuit(4), Single Chip Microcomputer (SCM) system(5), electric supply installation(6)Composition.Photoelectric sensor(3)Connect letter Number process circuit(4), Signal sampling and processing circuit connect Single Chip Microcomputer (SCM) system(5).When infrared light passes through from medicine bottle, if Then infrared light intensity then can receive air impact to have air in bottle.Once light intensity has difference with standard, according to the standard measuring The data of vacuum, then can be converted the vacuum thus in display bottle using Single Chip Microcomputer (SCM) system.
In the present embodiment, infrared transmitting tube(1)And photoelectric sensor(3)Spectrum be near infrared range, infrared emission Pipe adopts A3L3 (950nm), and photoelectric sensor adopts OPT101, because the suction to infrared tube of Carbon Dioxide in Air and vapor Receipts degree is larger.Shared by air, volume ratio is bigger, and light intensity is less.
Signal processing circuit in the present embodiment(4)Employed in chip be respectively LM324AD and AD790SQ, AD790SQ accurate voltage comparator, has rich and varied functional characteristic, and four computings that LM324AD carries very differential input are put Big device, has real Differential Input.
In the present embodiment, signal processing circuit(4)It is connected to LM324 backward end through two electric capacity of a resistance, for avoiding being tired of Disturb the input that signal passes to LM324, isolated with the bipolarity coupled capacitor of two electric capacity compositions.
In the present embodiment, Single Chip Microcomputer (SCM) system(5)It is made up of single-chip microcomputer, liquid crystal display and button etc., single-chip microcomputer adopts Chip STC12C2052AD, has 10 AD conversion inside this single-chip microcomputer, liquid crystal display adopts LCD1602.
In the present embodiment, 3 stand-alone keypad in Single Chip Microcomputer (SCM) system are respectively connected to 7,9,11 pins.
In the present embodiment, LCD1602 liquid crystal display 2-6 pin is respectively connected to 20,19 in STC12C2052AD chip, 18,17,16;Input signal Voltage accesses No. 12 pins of STC12C2050 chip.
Electric supply installation in the present embodiment(6)It is provided that two groups of DC voltages of 12V and 5V, LM324 12V direct current supply, AD790 is powered with 5V.
In the present embodiment, the infrared light medicine bottle that infrared transmitting tube (1) sends(2), received by photoelectric sensor (3) After be converted into the signal of telecommunication, then send signal processing circuit(4)Zoom into DC voltage, this DC voltage is by Single Chip Microcomputer (SCM) system(5)Enter Row AD collection and digital processing, send display.Work as medicine bottle(2)Vacuum different when, signal processing circuit(4)The unidirectional current of output Pressure is different, Single Chip Microcomputer (SCM) system(5)The result of display is different.The level of vacuum of medicine bottle thus can be detected with this device.
