Please refer to Fig. 1, Fig. 1 is the structural representation of the online ozone concentration detection apparatus being applicable to air purifier in a kind of embodiment of the utility model.
Change faint for ozone in environment is changed into electrochemical signals by sensor 1; Transition components 2 can adopt conversion element or the change-over circuit that current signal can be converted into voltage signal in prior art, electrochemical signals is changed into voltage signal by transition components 2, voltage signal is sampled through ADC sampling component 3, signal after sampling amplifies through two close cycles amplifier circuit device 7, two close cycles amplifier circuit device 7 effectively inhibits the shake of sensor 1, increase the stability that sensor 1 is measured, adopt two-stage amplifier, when not losing precision, signal can be amplified to enough multiples and change into voltage signal.Voltage signal carries out analog to digital conversion through A/D analog to digital converter 4.Software processing part adopts Kalman filtering algorithm, further increase the precision and stability that sensor 1 is measured, voltage signal is converted to digital signal with the signal frequency conversion of 4-20mA signal isolating converter and A/D analog to digital converter 4, digital signal input MCU processing components 5 stores, by digital signal filter process.Then, adopt RS485 communication protocol, by digital data transmission on the display 6 of air purifier, ensure the accuracy of data transmission.
The beneficial effects of the utility model are:
Online ozone concentration detection apparatus, can be loaded on optional position required in air purifier body, the levels of ozone in on-line real-time measuremen air purifier process pure air, accuracy of detection is high, stability is strong, and the data detected are transferred to display device show in real time.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
