Abstract

The utility model relates to an intelligent controller of a fish tank, wherein the intelligent controller is composed of an environmental parameter sensing module, a main control module, a user interaction module, and an external equipment driving module. The intelligent controller is characterized in that the main control module is respectively connected with the environmental parameter sensing module, the user interaction module, and the external equipment driving module. The environmental parameter sensing module senses the changes of environmental parameters like the water temperature, the water level and the oxygen-containing concentration and the like inside the fish tank; the non-electrical quantity change is converted into an electrical signal; and after the analog-to-digital conversion, the processed signal is sent to the main control module. The main control module carries out logical processing according to a related parameter threshold value set by the user interaction module in advance; when the related environmental parameter is lower or higher than the related threshold value, the external equipment driving module opens or closes related external equipment, thereby changing the environmental parameter of the fish tank.

Description

The fish jar intelligent controller

Technical field

The utility model relates to a kind of fish bowl controller, especially the fish jar intelligent controller.

Background technology

Tropical fish price in the market is also very high, feels more enervated, so people are often very careful in the process of raising, and particularly the living environment of fish is the part that people merit attention most, thereby the selection of fish jar is most important.Along with the development of modern science and technology development with rapid changepl. never-ending changes and improvements, particularly automatic control system, brought a lot of new ideas to people, the Intelligent fish tank of automatically controlling has just arisen at the historic moment, and the unusual desirable of market outlook.Fish jar is the necessary tool of breeding fish, and scientific and technological development has been arranged, and the novel fish tank with various additional functions also emerges in an endless stream on market.Some fish jars can be regulated the water temperature in cylinder, some fish jars can improve water quality by spray oxygen, equip in addition the fish jar of timed feeding device etc., and marched toward gradually intelligent, robotization, make these fish jars all there is certain scientific and technological content, for feeding tropical fish, provide convenience.

Summary of the invention

In view of above these situations, the utility model provides a kind of fish jar intelligent controller, and the employing single-chip microcomputer is core, then, at peripheral circuits such as expansion environmental parameter sensing module, external unit driver modules, has realized the control to electrical equipment in fish jar.

The utility model provides a kind of fish jar intelligent controller, comprise environment parameter sensing module, main control module, user interactive module, external unit driver module, it is characterized in that: main control module is connected with environment parameter sensing module, user interactive module, external unit driver module respectively.The variation of the environmental parameters such as water temperature, water level, oxygen concentration in environment parameter sensing module induction fish jar, and the variation of non electrical quantity is converted into to electric signal, be sent to main control module after analog to digital conversion, the threshold values of the correlation parameter that main control module arranges in advance by user interactive module carries out logical process, when the relevant environment parameter during below or above related threshold, by the external unit driver module, open or close corresponding external unit, thereby change the environmental parameter of fish jar.

The beneficial effects of the utility model are, 4 grades of display brightness are adjustable, have good man-machine interface, have the data power down and preserve, and a plurality of mode of operations can be selected for the user.This controller is stable, safe and reliable, has higher practicality.

Embodiment

In Fig. 1, the utility model provides a kind of fish jar intelligent controller, comprise environment parameter sensing module 1, main control module 2, user interactive module 3, external unit driver module 4, it is characterized in that: main control module 2 is connected with environment parameter sensing module 1, user interactive module 3, external unit driver module 4 respectively.The variation of the environmental parameters such as water temperature, water level, oxygen concentration in environment parameter sensing module 1 induction fish jar, and the variation of non electrical quantity is converted into to electric signal, be sent to main control module 2 after analog to digital conversion, the threshold values of the correlation parameter that main control module 2 arranges in advance by user interactive module 3 carries out logical process, when the relevant environment parameter during below or above related threshold, by external unit driver module 4, open or close corresponding external unit, thereby change the environmental parameter of fish jar.

Environment parameter sensing module 1 is mainly by being completed by ADS1110 and sensor.ADS1110 be a kind of precision, can continuous self-alignment serial a/d converter, with difference input and the resolution up to 16, the voltage error of measurement is 0.001 V, precision is high, its serial line interface is the I2C bus.Main control module 2 can be realized and being connected of ADS1110 by software simulation I2C bus.Concrete grammar is the I/O interface of single-chip microcomputer to be connected to data line SDA and the clock line SCL of I2C.Transmission by software control clock and data.It is controller that main control module 2 adopts STCl2C5A60S2 series enhancement mode 5l single-chip microcomputer.There are EEPROM, high-speed ADC in sheet inside, and temperature survey gets final product by the ADC measurement voltage signal after dividing potential drop with thermistor.EEPROM can be used to, to the data storage, realize data power down hold function.User interactive module 3 comprises and showing partly and key part, shows 8 sections 11 LED for part, carries out position by the mode of dynamic scan with S8550 and drives, and display brightness is high, and can carry out adjusting display brightness by the duty cycle adjustment to dynamic scan.Can the working condition of time, temperature and system be shown additional water pump and oxygen pump work indication animation effect.Key part has designed 11 buttons and 1 reset key altogether for completing the operation of various functions.What external unit driver module 4 adopted is that switching value is controlled, and has mainly adopted the MOC3021 photo-coupler.When 2 pin of MOC3021 set low level, in photoelectrical coupler MOC3021, luminotron is luminous, the photosensitive thyristor conducting, and triggering bidirectional triode thyristor TLC336A conducting, this gauge tap is in running order, controls by this way the external units such as outside heat pump, oxygen supply pump, bactericidal lamp, illuminating lamp.
