Description of drawings
The circuit block diagram of a kind of carbon monoxide transducer that Fig. 1 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; A kind of carbon monoxide transducer that provides for the utility model; Comprise the electric chemical formula Carbon Monoxide Detection element as sensitive element, electric chemical formula Carbon Monoxide Detection element connects signal processing circuit, and signal processing circuit connects the A/D change-over circuit; The A/D change-over circuit links to each other with microprocessor (English abbreviates MCU as); Microprocessor also connects power circuit, storage unit, signal output apparatus, outage output circuit, sound light alarming circuit, display unit and operating unit, and wherein, signal output apparatus and outage output circuit connect external unit through aviation plug.Operating unit is an infrared remote controller.
During work, the voltage transformation of the DC12～18V that power supply box, substation or other power-supply units is provided through power circuit for the voltage of+5VDC and-other unit of the voltage supply circuit of 5VDC.By electric chemical formula Carbon Monoxide Detection element.Absorb airborne carbon monoxide and the positive and negative electrode in inside carries out chemical reaction, output becomes the current signal of certain funtcional relationship with carbonomonoxide concentration.Through signal processing circuit, the current signal that sensitive element is exported converts voltage signal to again, through amplification, filtering, is input to the A/D change-over circuit then again, after the A/D conversion, obtains digital signal and is input to MCU again.MCU calculates and handles the digital signal of A/D change-over circuit input, and the data that obtain after calculating and handling are concentration value data of carbon monoxide.According to the concentration value data, the control signal output circuit makes its output frequency signal corresponding with extraneous carbon monoxide gas concentration again.Again its concentration value is presented at above the display unit intuitively.If gas concentration value is greater than or equal to the alarm set point setting value, the MCU guide sound optical alarm circuit of then giving an order sends the sound and light alarm signal; If gas concentration value is then controlled power-down circuit output power-off signal greater than outage point setting value.Operating unit in the circuit is an infrared remote controller, and this circuit receives and orders from control of remote controller.Infrared remote control can be controlled adjustment of MCU execution parameter and reset operation.Storage unit then is mainly used in the systematic parameters such as zero-error, linear coefficient of record sensor.
