Interface 112 exports the pulse signal of negative direction.When 112 current potential of second interface is height, and 111 current potential of first interface is low, electric current
Flow to first interface 111 from second interface 112, at this time by sampling resistor 130 by second electrode 122 relative to first electrode
In 121 voltage sample to AD (Analog to Digital, analog-converted number) Sampling Interface 113 of MCU controllers 110,
The voltage data of acquisition is converted to digital quantity, and the pass corresponding with TDS values of the voltage data by prestoring by MCU controllers 110
The digital quantity is converted into the output of TDS values by system；When 112 current potential of second interface be it is low, 111 current potential of first interface be it is high when, the dress
It sets and is detected without TDS, and eliminate the polarization phenomena work of water quality probe 120.Wherein, when electric current is from second interface 112
When flowing to first interface 111, for electric current by tested water body, which can be equivalent to certain resistance value, the voltage of acquisition
Data and the resistance value at certain proportionate relationship, the resistance value again with the conductivity of tested water body at certain proportionate relationship,
The conductivity of tested water body is again proportional with TDS values, therefore, can be converted to obtain tested water according to the voltage data of acquisition
The TDS values of body, and the correspondence of the voltage data and TDS values stored in difference TDS detection devices is by calculating in advance
It is obtained after correction.Since first interface 111 and second interface 112 are with the pattern output voltage of height pulse,
Be not in polarization phenomena between one electrode 121 and second electrode 122, substantially increase the service life of water quality probe 120
And reduce influence to measurement accuracy and tested water body water quality after water quality probe 120 polarizes.
To sum up, in the utility model embodiment, start detection pattern automatically after water quality probe meets water, mould is detected starting
Self-timing closes the detection pattern of high power consumption after formula, starts the standby mode of low-power consumption, can be to avoid TDS detection devices always
