Use well.Water temperature is controlled using microcontroller, not only with it is easy to control, configuration is simple, flexibility is high, into
The advantages that this is cheap, can also increase substantially the technical indicator of controlled temperature.
At present, water temperature control is widely used in the fields such as food, medicine, chemical industry, household electrical appliances, water temperature control system performance
Quality directly affects the quality of product.Therefore, water temperature control technology tool is studied to be of great significance.But in existing intelligence
It is single adjusting hot water therein when actual water temperature and inconsistent desired water temperature, in some documents in water temperature control system
Or water temperature is raised and lowered in cold water pipe, make the time that water temperature reaches desired value longer, it is uneconomical；Also having in a small amount of document is
The adjusting of water temperature is realized by more complicated algorithm model, due to the influence of many uncertain factors, water temperature control system
Accurate model be difficult to set up, even if corresponding accurate model can be set up, also can greatly improve the complexity of programming.
Common earth leakage protective device is mainly passive type protection according to operation principle, i.e.,：Performed again after first producing electric leakage behavior
Protection act, passive type protection is different with consequence caused by individual differences according to different power utilization environments, in extreme conditions
Can there are security risk.
Such as Chinese invention patent (publication number：103794425A) disclose a kind of earth leakage protective device, it include housing and
Primary clustering in housing.Primary clustering includes wiring board and buckle releaser mechanical structure component.The circuit of wiring board is used
Occur and send signals to the component action of control electromagnetic trip with over-pressed signal in checking to leak electricity.Buckle releaser mechanical structure component master
Include a main basal base, two groups of movable contact springs and static contact, a dropout plate, a push-pull rod.Main basal base is fixed on circuit
Plate.The earth leakage protective device of the present invention is used for electic protection, and when detection is leaked electricity, buckle releaser disconnects, to ensure that user pacifies
Entirely.
For another example Chinese invention patent (publication number：A kind of leakage protection circuit 104377647A) is disclosed, it includes electric leakage
Detection unit, for whether occurring to leak electricity in detection circuit and exporting electric leakage signal when leaking electricity.First circuit, including control
System switch, divider and protector.Connect after controlling switch and divider parallel connection with protector, the first circuit is receiving Lou
Supply line is cut off by protector during electric signal.The electric current of ON-OFF control circuit in the first loop is greater than or equal to preset value
When disconnect controlling switch, make current flow through divider carry out partial pressure, turn on controlling switch when electric current is less than preset value.First
When loop current is excessive, divider is connected and carry out partial pressure into the first circuit, reduce the electric current for flowing through protector, avoid protection
The excessive greater impact caused by the executing agency that coordinates with it of device electric current, enhances the electrical endurance of earth leakage circuit breaker.
When the first loop current is smaller, and meeting short circuit divider, it is ensured that protector has enough electric currents to flow through to disconnect at failure
Power supply.
