Abstract
The invention provides an automatic constant-temperature monitoring method for a fish tank thermostat which keeps water temperature constant by using characteristics of a peltier component. By the method, the change of water temperature can be automatically monitored; the monitored water temperature is compared with a preset water temperature range to determine whether the thermostat needs to automatically run; when the thermostat needs to run, power properties output to the two poles of the peltier component are determined by determining whether the water temperature is higher than the preset water temperature upper limit or lower than the preset water temperature lower limit to make the peltier component cool or heat water on an external surface of the shell, so that the water temperature is kept constant in the preset range.

Embodiment
Existing according to description of drawings operation principle of the present invention:
As depicted in figs. 1 and 2; A kind of automatic constant-temperature monitoring method of fish tank thermostat; Fish tank thermostat is placed on the filtering trough of fish jar; Mainly form by shell 1, the casing cover 2 that is mounted with control panel 3, temp probe 4, water level switch 5, first radiator 6, blower fan 7, second radiator 8, control circuit board 9, peltier-element 10, alarm 11 and power panel 12; Peltier-element 10 is placed in the perforate of shell 1 bottom, and the one side outside shell 1 is connected with second radiator 8, and the one side in shell 1 is connected with first radiator 6; Control panel 3 is provided with that temperature display, on & off switch, the water temperature upper limit are provided with key, the water temperature lower limit is provided with key; Described control circuit board 9 is made up of control system and circuit board, and the input of described control circuit board 9 connects with control panel 3, temp probe 4, water level switch 5, power panel 12, and output connects with the two poles of the earth, the alarm 11 of control panel 2, blower fan 7, peltier-element 10.
Fish tank thermostat is placed in the filtering trough, earlier according to the requirement of the fish of being supported in the fish jar to water temperature, sets the temperature range of water, i.e. the water temperature lower limit and the water temperature upper limit through control panel 3 before using.Water in the fish jar is under the effect of the water pump that filtering trough is equipped with; When flowing into filtering trough; The temp probe 4 of fish tank thermostat, water level switch 5 and second radiator 8 just all can be soaked in water, because water is constantly to flow, the water temperature that temp probe returns is close with the water temperature in the fish jar.
Described control system monitors the variation of water temperature, the instruction that on & off switch is sent automatically; Water temperature that monitors and predefined water temperature range value are compared, thereby need to determine whether Auto Power On work, when needs start work; Be to be higher than the predefined water temperature upper limit further according to water temperature; Still be lower than predefined water temperature lower limit, confirm to output to the power attributes at peltier-element 10 the two poles of the earth, make the one side refrigeration or the heating of peltier-element 10 outside shell 1.
When the control system detected initial power-up or receives the start-up command that on & off switch transmits, the control system judged whether water level switch 5 is in on-state earlier, if do not have connection; There is not water to flow through in the expression filtering trough; Then report to the police,, read the value that temp probe 4 returns if connect; The value of returning when temp probe 4 is lower than predefined water temperature lower limit, operation water heating schedule; The value of returning when temp probe 4 is higher than the predefined water temperature upper limit; Operation water refrigeration program; After the program running of water heating schedule or water refrigeration finished, the control system continued the instruction and the variation of water temperature that the monitoring on & off switch is sent, and the temperature value that returns when water level switch 5 connections and temp probe 4 is not in predefined scope; The control system starts water heating schedule or water refrigeration program once more, so moves in circles.
