PH value and liquid level, and the signal detected sends the control chip 1 to, carries out relevant treatment by the control chip 1.
It should be noted that the temperature sensor 3, the pH sensor 4 in the utility model are in the prior art existing
Sensors, structure and testing principle are known to persons skilled in the art, therefore details are not described herein.
The input terminal of the temperature alarm circuit 6, the input terminal of the PH warning circuit 7, the LCD display 9 it is defeated
Enter end to connect with an output pin of the control chip 1 respectively.
In the present embodiment, the control chip 1 is judged based on the temperature signal that the temperature sensor 3 received transmits
Whether the temperature value of water is more than predetermined value in fish tank body.When temperature value is more than predetermined value, the control chip 1 sends first
Signal is controlled to the temperature alarm circuit 6, the temperature alarm circuit 6 issues the first alarm signal.Specifically, such as Fig. 2 institute
Show, the temperature alarm circuit 6 in the present embodiment includes triode Q1, Light-emitting diode LED 1 and relay S1, in which: institute
The base stage for stating triode Q1 is the input terminal of the temperature alarm circuit, connects an output pin of the control chip 1,
The emitter of the triode Q1 is grounded.The cathode of the Light-emitting diode LED 1 connects the collector of the triode Q1, institute
State the anode connection power end of Light-emitting diode LED 1.A coil pin of the relay S1 connects the triode Q1's
Another coil pin of collector, the relay S1 connects power end.In the present embodiment, the relay S1 uses model
For the relay of SRD-05VDC-SL-C, which includes 5 pins, wherein 2 be coil pin, 1 be common end,
1 be normally open end, 1 be normal-closed end.It is specific:
When temperature value is no more than predetermined value, the control chip 1 issues a high level to the temperature alarm circuit 6
(base stage of the i.e. described triode Q1), the triode Q1 is in off state at this time, and the Light-emitting diode LED 1 is extinguished, institute
State relay S1 disconnection.
When temperature value is more than predetermined value, the control chip 1 issues a low level (first control signal) to described
Temperature alarm circuit 6 (base stage of the i.e. described triode Q1), the triode Q1 conducting, the Light-emitting diode LED 1 connect at this time
Energization source is lit (the first alarm signal) to remind user to handle the water in fish jar, while the line of the relay S1
Enclose electric so that relay S1 is closed.
Further, since the coil of relay S1 can generate very strong reversed electricity when triode Q1 sports cut-off by being connected
Kinetic potential, it is easy to puncture triode Q1.Therefore, as shown in Fig. 2, as a preferred embodiment, the temperature alarm circuit 6 is also
Including sustained diode 1, the anode of the sustained diode 1 connects the collector of the triode Q1, two pole of afterflow
The cathode of pipe D1 connects power end.In the present embodiment, the 1 model 1N4148 of sustained diode.
Further, when the water temperature in tank body of fish tank is more than predetermined value, in order to realize automatic cooling.It is some more preferably
In embodiment, frigistor can also be set in fish tank body.Particularly, the relay S1 accesses to frigistor
Start-up circuit (such as relay S1 is connected between power end and the power access end of frigistor), the relay at this time
S1 is equivalent to starting switch for the frigistor.It is described small when relay S1 closure (temperature is more than predetermined value)
The starting of type refrigerator, the frigistor can be realized the cooling to water in fish tank body at this time.
As is well known by persons skilled in the art, water temperature and the molten amount of water oxygen are in inverse ratio, when water temperature over-high, in water
The molten amount of oxygen is too low.Therefore, in other more preferably embodiment, it can also be arranged outside fish tank body and be connected to fish tank body
Oxygenating pump.Particularly, the relay S1 accesses to the start-up circuit of oxygenating pump, and the relay S1 is equivalent to described at this time
Oxygenating pump starts switch.When relay S1 closure (temperature is more than predetermined value), the oxygenating pump startup is described at this time
Oxygenating pump can be realized the oxygenating to water in fish tank body.
The control chip 1 judges water in fish tank body based on the pH value signal of the pH sensor 4 transmission received
PH value it is whether abnormal, exception described herein can be high lower than predetermined lowest value (acidity of water is excessively high) or pH value for pH value
In predetermined peak (alkalinity of water is excessively high).When pH value exception, the control chip 1 sends second control signal to the PH
Warning circuit 7, the PH warning circuit 7 issue the second alarm signal to remind the pH value in fish tank body abnormal.
In the present embodiment, the circuit composed structure of the circuit structure of the PH warning circuit 7 and the temperature alarm circuit 6
Essentially identical, existing unique difference is that the PH warning circuit 7 uses buzzer as alarm element.Due to above
The structure and working principle of temperature alarm circuit 6 is described in detail, therefore no longer to the structure and work of PH warning circuit 7
It is repeated as principle, those skilled in the art are when implementing the utility model, it is only necessary to will be in the temperature alarm circuit 6
Light-emitting diode LED 1, which replaces with buzzer, can obtain the PH warning circuit 7.
When pH value exception, the control chip 1 issues a high level to 7 (i.e. described three pole of PH warning circuit
The base stage of pipe Q1), the triode Q1 is in off state at this time, and the buzzer does not work, and the relay S1 is disconnected.When
When pH value exception, the control chip 1 issues a low level (the i.e. described second control signal) to the PH warning circuit 7
(base stage of the i.e. described triode Q1), the triode Q1 conducting, the buzzer power on and issue buzzing (second at this time
Alarm signal) to remind user to handle the water in fish jar, while the coil of the relay S1 obtain it is electric so that relay
S1 closure.
Likewise, when the pH value exception in tank body of fish tank, in order to realize the adjusting to pH value.More preferably implement some
In example, water circulating pump can also be set outside fish tank body, the water circulating pump is connected to fish tank body and outside by whose water pipe
Water source.Particularly, the relay S1 accesses to the start-up circuit of water circulating pump (such as relay S1 is connected on power end and circulation
Between the power access end of water pump), the relay S1 is equivalent to starting switch for the water circulating pump at this time.When the relay
When device S1 is closed (pH value is abnormal), the water circulating pump starting, to realize the water in the water and external water source in fish tank body
Displacement.
The LCD display 9 is then for showing the temperature and pH value of the water in fish tank body, to realize to fish tank body
The intuitive display of interior water quality.
Please continue to refer to shown in Fig. 1, in certain embodiments, the Intelligent fish tank of the utility model further includes that liquid level passes
Sensor 5 and pump 8 of surging, the output end of the liquid level sensor 5 is connect with an input pin of the control chip 1, described
Pump 8 of surging is connect with an output pin of the control chip 1.The pump 8 of surging is connected to fish tank body and outside through water pipe
Water source.
Liquid level of the liquid level sensor 5 for the water in fish tank body, and the signal detected send to it is described
Chip 1 is controlled, relevant treatment is carried out by the control chip 1.Similarly, the liquid level sensor 5 in the utility model is existing
There are an existing sensors in technology, structure and testing principle be known to persons skilled in the art, therefore
This is also repeated no more.
The control chip 1 judges water in fish tank body based on the liquid level signal of the liquid level sensor 5 received
Whether liquid level is lower than predetermined value.When the liquid level of water in fish tank body is lower than predetermined value, the control chip 1 sends third control
Signal (such as a low level) is to the start-up circuit of the pump 8 of surging, and 8 starting of pump of surging is thus by the water pump of external water source
Enter to moisturizing of the realization to fish tank body in fish tank body.
