Embodiment
A kind of long-range water quality detection mechanism, it is characterized in that: at least comprise housing 1, housing 1 one sides have the water inlet 6 of detection, opposite side has the water out 4 of detection, detect water inlet 6 and detect water out 4 that this has detected liquid cell 5, mercurous chloride electrode 3 and calcium electrode 2 respectively one end stretch in detected liquid cell 5, and the other end is electrically connected to treatment circuit 7, and treatment circuit 7 is connected with gsm module 9 and GPS module 10 by interface.
As shown in Figure 1, at least comprise housing 1, housing 1 one sides have the water inlet 6 of detection, opposite side has the water out 4 of detection, detect water inlet 6 and detect water out 4 that this has detected liquid cell 5, mercurous chloride electrode 3 and calcium electrode 2 respectively one end stretch in detected liquid cell 5, the other end is electrically connected to treatment circuit 7, treatment circuit 7 is connected with gsm module 9 and GPS module 10 by interface, GPS module 10 is for locating the position of long-range water quality detecting device, and gsm module is for sending to pulpit by positioning signal and detection data.
On the body that detects water inlet 6 extensions, there is flowmeter, to obtain the relation that dynamically obtains water hardness and flow.
As shown in Figure 2, treatment circuit 7 comprises two-way emitter follower IC1 and IC2, two-way emitter follower consists of two amplifiers, two-way measuring amplifier IC3 and IC4, two-way measuring amplifier is comprised of three amplifiers, mercurous chloride electrode 3 and calcium electrode 2 are electrically connected to respectively the input end of two-way emitter follower IC1 and IC2, and the output terminal of two-way emitter follower IC1 and IC2 is electrically connected to the single-chip microcomputer input port with A/D conversion, and single-chip microcomputer one I/O is electrically connected to gsm module 9.Treatment circuit 7 is electrically connected with LCD display 11 and keyboard circuit 12, by LCD display and keyboard circuit input water hardness warning upper lower limit value, by LCD display, shows flow, temperature, water hardness value.
Single-chip microcomputer with A/D conversion is mas430.
Principle of the present invention is: the ability of water hardness refer initially to calcium, magnesium ion precipitation soap.The total hardness of water refers to the total concentration of calcium in water, magnesium ion, comprising carbonate hardness (calcium precipitating with carbonate form by heating energy, magnesium ion, therefore be again temporary hardness) and non-carbonate hardness (part calcium, the magnesium ion that can not precipitate after heating, claim again Permanent hardness).Generally calcium ion is maximum to the contribution of total hardness, and for relatively-stationary a certain area, the shared ratio of calcium ions and magnesium ions is again relatively stable, so, detect calcium ion concentration, just indirectly shown the total hardness of local water quality.
Calcium electrode is as detecting electrode, and mercurous chloride electrode is as contrast electrode, and calcium electrode, mercurous chloride electrode form primary element with detected boiler feed water.
The electromotive force of primary element is relevant to the calcium ion concentration in tested water, the small electric kinetic potential of primary element is amplified, then compare with inner reference voltage Ef, if illustrating into water hardness, the small electric kinetic potential Ex> reference voltage Ef of primary element exceeds standard, instrument is reported to the police, otherwise does not report to the police.Before the use first of calcium electrode, according to the request for utilization of electrode, need to add in 0.1 mole of lime chloride and fill solution (instrument is with), then invade bubble and in water to be detected, activate 24 hours.Calcium electrode belongs to exact instrument, and the PVC film of electrode front end has ion and selects permeation, can not use hard object contact, in order to avoid damage.The high impedance plug of calcium electrode lead-in wire, answers the socket bottom at the inserting instrument back side, and then tightening fixed screw can use.
Mercurous chloride electrode needs to add saturated Klorvess Liquid in mercurous chloride electrode after using continuously a period of time, and need to maintain the potassium chloride of separating out on a small quantity, and calcium electrode is used the time about 2 months continuously, also will add 0.1 mole of calcium chloride solution.Note, in mercurous chloride electrode, can not have bubble, in order to avoid " salt bridge " opens circuit.
