Described power supply unit is battery, and display unit is liquid crystal display, and control module is MSP430 chip.
The utility model can be completely real-time the situation of continual monitoring water quality, reflect the truth of water-quality guideline, ensure the safety of water quality that convenient test and simple and practical is beneficial to maintenance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1 is functional block diagram of the present utility model;
Fig. 2 is the structural drawing that the utility model is not installed to pipeline;
Fig. 3 is the cut-open view that the utility model is installed to pipeline.
Embodiment
Embodiment: as shown in Figure 1, the utility model provides a kind of embodiment of water quality on-line testing instrument, and its hardware circuit comprises control module 10, exports the display unit 20 be connected, the multiple sensors providing the power supply unit 30 of electric power support to control module 10, provide the sampling unit 40 of sampled signal, provide the signal processing unit 50 of signal and be connected with signal processing unit 50 to sampling unit 10 to control module 10 with control module 10.Sensor comprises pH value sensor 61, conductivity sensor 62, residual chlorine sensor 63, TDS (Total dissolved solids) sensor 64, temperature sensor 65.Wherein be provided with buffer circuit 66 between conductivity sensor 62 and residual chlorine sensor 63 and between residual chlorine sensor 63 and TDS sensor 64.PH value sensor 61, conductivity sensor 62, residual chlorine sensor 63, TDS sensor 64 are electrochemical sensor.Power supply unit 30 is preferably battery.In water quality, the accuracy of the test result of pH value, conductivity, TDS, chlorine residue all follows temperature relevant in addition, that is, needs to do temperature compensation and just can obtain result more accurately.Conventional temperature compensation algorithm has been done in control module 10 inside, and according to the Current Temperatures of the water obtained from temperature sensor, other parameters can be shown on display unit 20 according to the exact value after compensation.Because electrochemical sensor can realize the output of voltage to the variable concentrations of fluid to be measured or electric current by chemical reaction, so different interference can be produced between sensor from sensor, test result can be affected, therefore do corresponding quarantine measures by buffer circuit 66, solve because interfere with each other the problem affecting test result.
During work, be responsible for the test to water quality by sensor, produce different voltage or current signal, enter sampling unit 40 after signal processing unit 50, sampling unit 40 carries out analog to digital conversion to sensor one by one.The data-signal obtained carries out calculating by control module 10 and resolves, and is finally shown on display unit 20.Because system adopts powered battery, power consumption is the emphasis needing to consider, the MSP430 that the utility model adopts TI company to provide is as Master control chip, low in energy consumption, integrated level is high, there is the unit storing separately data inside, can store parameters measure required for curvilinear equation, make system simple and convenient, stability is improved, the mode that software section uses sleep and interruption to wake up reduce further the power consumption of system, and integrated multi-parameter sensor, when avoiding that on market, various isolated sensor is integrated, volume is large and fall apart, the shortcoming that line is many and assorted, ensure that stability and the reliability of Meter Test.
As Figure 2-3, be physical construction of the present utility model, it is the table header 21 be arranged on pipeline 1, and pipeline 1 is provided with patchhole 12 and is positioned at the external thread 14 of patchhole 12 periphery.Table header 21 comprises support bar 22, be positioned at support bar 22 one end and can extend into patchhole 12 electrode 23, be positioned at support bar 22 other end display unit 20, be set in the O-ring seal 24 on support bar 22 and to be positioned at above O-ring seal 24 and with the nut 25 of external thread lock fit.Wherein electrode 23 and sensor are electrical connected.The utility model can detect the conventional index of pH value in water, conductivity, TDS, chlorine residue, temperature 5 water quality detections.The utility model adopts integrated sensor, and due to the sensor used be electrochemical sensor (except temperature), there is serviceable life, conveniently user changes, the utility model have employed the sensor connected mode of changeable type, as long as old sensor is screwed down from support bar 22, then it is just passable to screw on a new sensor, convenient practical again.
The utility model solves common test instrument can not the problem of real-time testing multiple-quality water parameter continuously; Solve original those in order to test the many kinds of parameters of water quality, can make large and assorted equipment, this instrument volume urine is in installation, and be convenient to safeguard, Measurement sensibility is accurate; And solve more current online instrument, and once after sensor runs out of, the problem need changed together with instrument.
Certain above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
