Description
Technical field
The utility model proposes a kind of checkout equipment, especially relate to the water quality test pencil that a kind of precision is high.
Background technology
Along with growth in the living standard, the concern of people to self health status is more and more higher, but taking place frequently of food in recent years and drinking water safety problem, make people greatly alarmed, especially every day potable water directly drink, be directly connected to the health status of people, therefore need the whether potable device of a kind of test water quality, and the TDS value of water weighs the important indicator of water quality.TDS is the abbreviation of English Total Dissolved Solids, refers to the total content of the solid matter be dissolved in the water, comprises salt, metallic ion, mineral matter etc.Unit is ppm or mg/L.It shows to be dissolved with how many milligrams of total dissolved solids in 1 premium on currency, the total ion concentration in other words in 1 premium on currency.TDS value represents dissolved matter impurity content in water, and TDS value is larger, illustrate that the impurity content in water is large, otherwise impurity content is little.
Water quality tester in the market, general structure is complicated, volume more greatly, not portable, and accuracy of detection is low, and power consumption is high, often need change battery.
Utility model content
In order to solve the problem, the utility model provides the water quality test pencil that a kind of accuracy of detection is high, volume is little, power consumption is low.A kind of water quality test pencil that the utility model provides, the technical scheme of employing is as follows:
A kind of water quality test pencil, comprise: processing module, supply module, temperature and TDS data acquisition module, key-press module, download program module, reseting module, division module, display interface device module, supply module, temperature are connected with processing module respectively with TDS data acquisition module, key-press module, download program module, reseting module, division module, display interface device module.
Being characterized as processing module is further single-chip microcomputer.
The model being characterized as single-chip microcomputer is further RENESAS R5F10RBCAF.
Be characterized as further and also comprise: alarm module, alarm module is connected with processing module.
The utility model compared with the existing technology, has the following advantages and beneficial effect:
1, the utility model is compared with prior art, has the advantage that testing precision is high, and error range is only ± and 1%.
2, the utility model in use, and when detecting that cell voltage runs lower than automatically switching to low-power consumption mode during 2.09V, the service time of the battery greatly extended, more than 2 years normal service time, without the need to frequently changing battery.
3, the utility model is while measurement water quality, directly can test water outlet temperature at that time, be shown to user by display, and according to the temperature of current water automatically provide penalty coefficient carry out TDS value conversion, thus the impact of water temperature on TDS value drops to minimum, substantially increases measuring accuracy.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structured flowchart of a kind of water quality test pencil of the utility model;
Fig. 2 is the circuit connecting relation figure of a kind of water quality test pencil of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment
As depicted in figs. 1 and 2, a kind of water quality test pencil, comprise: processing module 1, supply module 2, temperature and TDS data acquisition module 3, key-press module 4, download program module 5, reseting module 6, division module 7, display interface device module 8, supply module 2, temperature are connected with processing module 1 respectively with TDS data acquisition module 3, key-press module 4, download program module 5, reseting module 6, division module 7, display interface device module 8.
Optimal way of the present utility model is: processing module 1 is single-chip microcomputer.
The model of single-chip microcomputer is RENESAS R5F10RBCAF.
Also comprise: alarm module 9, alarm module 9 is connected with processing module 1.
The utility model in use, water quality test pencil is put into water source to be measured by user, press test button, temperature and TDS data acquisition module 3 gather water temperature and the TDS data at water source to be measured, water temperature data demonstrates the temperature value of current water temperature after AD conversion by the display be connected with display interface device module 8, processing module 1 provides after penalty coefficient carries out the conversion of TDS data according to current water temperature automatically, and TDS data demonstrate the TDS numerical value at current water source after AD conversion by the display be connected with display interface device module 8; When water quality test pencil operation irregularity, alarm module 9 is sounded a buzzer prompting user, and user is by after pressing the reset key in reseting module 6, and water quality test pencil recovers normal operating conditions; When the voltage of supply module 2 is lower than 2.09V, processing module 1 automatically switches to low power mode of operation, and carries out low electricity prompting by display.
The utility model compared with prior art, has the advantage that testing precision is high, and error range is only ± and 1%.
In use, when detecting that cell voltage runs lower than automatically switching to low-power consumption mode during 2.09V, the service time of the battery greatly extended, more than 2 years normal service time, without the need to frequently changing battery for the utility model.
The utility model is while measurement water quality, directly can test water outlet temperature at that time, be shown to user by display, and according to the temperature of current water automatically provide penalty coefficient carry out TDS value conversion, thus the impact of water temperature on TDS value drops to minimum, substantially increases measuring accuracy.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
