Description

Water quality monitor capable of automatically calibrating sensor Technical Field The invention relates to the technical field of water quality monitoring, in particular to a water quality monitor capable of automatically calibrating a sensor. Background The swimming pool is used as a public place for recreation, recreation and body-building exercises, the water quality safety is directly related to the health of users, namely, residual chlorine, pH value and turbidity are not up to standard, bacterial viruses are easy to breed, skin allergy and eye infection are caused, and if urea exceeds the standard, the pool water is not replaced timely. But unlike drinking water, industrial water, swimming pool water quality monitoring does not need absolute accurate detection data, and more central needs are long-term stable operation under relatively accurate conditions so as to reduce the cost of manual maintenance. The current general water quality monitor has obvious defects when being applied to swimming pools, namely (1) a sensor probe is easy to adsorb pollutants (such as hair and tiny particles) in a water sample, so that data is distorted, frequent manual disassembly and cleaning are needed, the maintenance cost is high, (2) fluctuation of the flow rate of the water sample (such as water supplement of the swimming pool and start and stop of a circulating pump) can interfere with a detection result to influence the stability of the data, and (3) the sensor performance is floated and then depends on manual calibration, so that the data is distorted if no worker is calibrating, the monitoring significance is lost, and the durability of the probe is further reduced by frequent disassembly. The above problems lead to the difficulty of adapting the conventional apparatus to the requirement of "low maintenance and stable operation" of the swimming pool, and therefore there is a need for a monitoring device that is optimized for the working condition of the swimming pool and that combines stability, durability and maintenance-free.
