Accompanying drawing explanation
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
Embodiment
Embodiment of the present utility model: as shown in Figure 1, microprocessor 1 adopts existing uPSD3234A-40U6 chip, and the function of a CPU is not only by microprocessor 1, and it also has the space storing data and program.UPSD3234A has two panels flash storage, and wherein the main Flsah storer of 128K is for filling program; Secondly the secondary Flash of 32K is for storing data.Microprocessor 1 connecting fluid crystal display screen 2, touch screen LCDs 2 adopts MGLS-19264, major function be to ion concentration value and Temperature displaying out, and provide the operation interface of full Chinese, person's operation easy to use.The MGLS-19264 selected can provide the display of figure, letter and Chinese character.Microprocessor 1 connects the AD1112IDGST that AD sampling module 3, the AD sampling module 3 being used for image data selects binary channels 16, and a passage adopts temperature, and a passage adopts ion concentration value.AD sampling module 3 connects processes temperature signal module 4 and ion concentration signal processing module 5 respectively; Processes temperature signal module 4 adopts the MC1403 of a SOP8 paster encapsulation to provide constant 2.5V voltage, adopts the principle of electric resistance partial pressure, draws temperature value for the sampling of AD sampling module 3 chip.Ion concentration signal processing module 5 adopts AD620AR, 272C chip to gather ion concentration value signal, and for ADS1112IDGST sampling, volume is 1/5 of the signal processing part partial volume of conventional ion densimeter.Microprocessor 1 also connects the photoelectric isolation module 6 for exporting, and photoelectric isolation module 6 connects DAC output module 7 and height alarm module 8, DAC output module 7 connects voltage transitions current module 9.Photoelectric isolation module 6 effect is output common ion concentration value part not common-battery source, does not disturb each other.DAC output module 7 adopts DAC7512 chip, and volume only has 1/20 of common DAC chip, and height alarm module 8 mainly provides on-off model.Voltage transitions current module 9 adopts LM324 chip.DAC output module 7 is that the number of 12 touches conversion chip, digital signal is converted to the voltage of 1 ~ 5V, then converts the electric current of 4 ~ 20mA to by voltage transitions current module 9.
Microprocessor 1 is connected with the clock module 10 of displaying time, and clock module 10 adopts DS12C887, and major function is for the ion concentration value of instrumentation function and autostore provides time reference.
Processes temperature signal module 4 connects temperature sensor 11, and ion concentration signal processing module 5 connects ion concentration electrode 12.
The power module 13 that wiring board is arranged adopts HAT10-0512-NF and HDN3-5S24, alternating current 220V Power convert is become direct current 5V and ± 12V, then the 5V of direct current is converted to 24V.
Microprocessor 1, touch screen connect LCDs 2, AD sampling module 3, processes temperature signal module 4, ion concentration signal processing module 5, photoelectric isolation module 6, DAC output module 7, height alarm module 8 and voltage transitions current module 9 and are all integrated on surface-mounted integrated circuit.
