Having occurred a kind of free-changing water self-cleaning fish bowl now on the market, is 02251707.3 free-changing water fish jar water treatment facilities as the patent No., though changed the inferior position of traditional fish jar in the past, exists simultaneously to cost an arm and a leg, and animals and plants are difficult for shortcomings such as adjustment in the fish jar.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of intelligent fish tank capable of changing water is provided, this intelligence fish tank capable of changing water adopts intelligence control system to finish from moving water, have the water level of maintenance, control switching, clock adjustment, warning function, not only object can arbitrarily exchange in simple installation but also the fish jar.

The utility model implementation is as follows:

This intelligent fish tank capable of changing water, comprise fish jar body, be located at switch electromagnetic valve, intelligent control module, keyboard, LCD display, dc source on water inlet and the delivery port with water inlet and delivery port, it is characterized in that described intelligent control module is the control core with the single-chip microcomputer, described single-chip microcomputer is electrically connected with the pressure sensor of being located at the fish jar bottom by A/D change-over circuit and amplifying circuit, described single-chip microcomputer is connected with PC through serial communication circuit, described single-chip microcomputer is connected with buzzer through warning circuit, and described single-chip microcomputer is connected with indicator lamp through indicator light circuit.

The model of above-mentioned single-chip microcomputer is the P89C58X2 of PHLIPS.

Above-mentioned A/D change-over circuit is the ADC0809 successive approximation converter.

Above-mentioned amplifying circuit is an AD620 high accuracy instrumentation amplifier.

Above-mentioned pressure sensor is for adopting the piezoresistive transducer of SY11 pressure core body.

IC in the above-mentioned serial communication circuit is MAX232.

Above-mentioned indicator lamp is a light emitting diode.

The utility model is the control core with the single-chip microcomputer, adopts highly sensitive piezoresistive transducer that the fish jar water level is monitored, and changes water level by the control magnetic valve.The utility model has been realized functions such as the moving water certainly, keep water level of fish jar, control switching, clock adjustment, alarm clock adjustment and warnings, not only have perfect in shape and function, advantage that control accuracy is high, and simple installation, cheap, object can arbitrarily exchange in the fish jar.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As depicted in figs. 1 and 2, the intelligent fish tank capable of changing water of this kind, comprise have water inlet (6) and delivery port (7) fish jar body (4), be located at switch electromagnetic valve (5), intelligent control module, keyboard, LCD display, the dc source of water inlet (6) and delivery port (7).

Above-mentioned intelligent control module serves as a control core (as Fig. 3) with single-chip microcomputer (1), described single-chip microcomputer (1) is electrically connected with the pressure sensor (8) of being located at the fish jar bottom by A/D change-over circuit (as Fig. 4) and amplifying circuit (as Fig. 5), described single-chip microcomputer (1) is connected with PC through serial communication circuit (as Fig. 6), described single-chip microcomputer (1) is connected with buzzer through warning circuit, and described single-chip microcomputer (1) is connected with indicator lamp through indicator light circuit (as Fig. 7).
