Current known water quality on-line monitoring device, weak point is:
1, without antifreeze heating arrangement, generally can only the outdoor use in southern area.Be applied to cold northern area, can only in indoor use.For the small towns water factory that northern part is remote, even indoor temperature is also lower than zero degree, causes water route part to freeze, sensor cisco unity malfunction;
2, device is without water intaking valve and outlet valve, causes in storage and transportation, and the electrode of water quality transmitter exposes in atmosphere, is easily oxidized, and reduces serviceable life; And when monitoring, water flows into from water inlet, flows out waste water resource from water delivering orifice always;
3, monitor the principle that turbidity generally adopts Photoelectric Detection, the water capacity of flowing easily causes light path unstable, measured turbidity less stable.
Utility model content
The utility model proposes a kind of anti-freeze type water quality on-line monitoring device that can be used for cold district all-weather outdoor and use, and water can be kept static when test, stably obtain each Monitoring Data.
For achieving the above object, this real utility model is achieved through the following technical solutions:
A kind of anti-freeze type water monitoring device, comprise single-chip microcomputer, the synthermal sensor of described single-chip microcomputer, wireless data sending DTU, water quality transmitter connect simultaneously, it is characterized in that: also comprise power resistor, and be arranged at water intaking valve and the outlet valve of water inlet pipe and water outlet pipe part respectively, described power resistor is connected with single-chip microcomputer by the first relay, and described water intaking valve is connected with single-chip microcomputer respectively by the second relay and the 3rd relay with outlet valve.
Preferably, described power resistor adopts AC220V to power, and maximum temperature can reach 65 DEG C, power 300W.
Preferably, described first relay, the second relay and the 3rd relay are technical grade closed type relay.
Preferably, described water intaking valve, outlet valve are solenoid valve.
Preferably, described temperature sensor adopts digital temperature sensor DS18B20.
By technique scheme, the beneficial effects of the utility model are:
1, compared to existing technology, the utility model is provided with water intaking valve and outlet valve respectively at water inlet pipe and water outlet pipe part.The beneficial effect done like this is, part water quality transmitter adopts optical detection principle, and when other like product detects, water is constantly flowing, and the water of flowing can affect light path, and data fluctuations is larger, and then affects acquisition precision.The technical program is when image data, single-chip microcomputer opens water intaking valve and outlet valve by relay, water is made to enter each water quality monitoring transmitter from water inlet pipe, then close water intaking valve and outlet valve, transmitter under the static state of water, by water quality condition (pH value, conductivity, turbidity, chlorine residue etc.) convert current signal to, send single-chip microcomputer to; In observation process, water is stablized static, and compared to the water of flow state, the data collected are more stable.
2, when system cut-off, water intaking valve and outlet valve automatic closing water road, can saving water resource, and when transporting or store, due to water inlet and water outlet closed electromagnetic valve, be filled with water in each water quality transmitter can not flow out, the electrode of each transmitter is all immersed in water, can not be oxidized the life-span affecting electrode.
3, by the setting of power resistor, realize single-chip microcomputer through temperature sensor harvester internal temperature, when temperature is less than setting value, Single-chip Controlling relay closes, power resistor starts heating power, make the water route parts such as the transmitter of device inside, water pipe can not cause water freezing because of low temperature, cisco unity malfunction.
