Abstract
The utility model relates to an automatic water-replenishing control system special for a cell incubator. The automatic water-replenishing control system comprises a water pan which is arranged in the cell incubator, a gravity sensor, an electromagnetic valve, a water inlet tube and a central processing unit which consists of a central processor, an analog/digital (A/D) converter and a digital/analog (D/A) converter, wherein the gravity sensor is arranged under the water pan and is connected with the input end of the A/D converter; the output end of the A/D converter is connected with the central processor; the central processor is connected with the electromagnetic valve through the D/A converter; the electromagnetic valve is arranged on the water inlet tube; and one end of the water inlet tube is arranged on the water pan, and the other end of the water inlet tube is communicated with a water source. As the automatic water-replenishing control system is arranged on the cell incubator, a proper amount of water is replenished into the water pan in the cell incubator timely and automatically, and the problems that the water is difficult to replenish in time and the amount of the water to be replenished is difficult to control accurately when the water is replenished manually are solved.
Description
Technical field
The utility model relates to the utility appliance of cell culture apparatus, what be specifically related to is the Special Automatic make-up water supply control system of a kind of cell culture incubator.
Background technology
Cell culture incubator is one of conventional instrument of generally using of biology laboratory, and cultured cells is grown better in order to make, and incubator inside must maintain the environment of a specified temp, humidity.But most middle-size and small-size incubator mainly still is employed in box house configuration water pond at present, and the inner high humidity environment of incubator is kept in manual work moisturizing in water pond.This method exists deficiency to be: the one, and artificial recharge does not accomplish all to be in time especially on time the water pond moisturizing at every turn, if operator add water in case carelessness has been forgotten, can cause the culture experiment failure because of the water pond lack of water; The 2nd, the water yield of supply can't accomplish that precisely water storage is very few, causes the frequent water that adds, and will certainly cause the fluctuation of temperature and humidity in the cell culture incubator, and water storage is too much, and breed bacteria is polluted environment in the case easily.Therefore, timely and appropriate discovery moisturizing in cell culture incubator is a precondition of improving the cell growing environment, and this also is the problem that those skilled in the art are badly in need of solving.
Summary of the invention
The goal of the invention of the utility model is to the problems referred to above kind of the Special Automatic make-up water supply control system of a kind of cell culture incubator to be provided, and in cell culture incubator, replenishes the water source timely and appropriately, solves the problem of the untimely and uncontrollable water yield of artificial recharge existence.
The utility model is realized through following technical scheme: the Special Automatic make-up water supply control system of cell culture incubator comprises the water pond that places cell culture incubator inner; This system also comprises gravity sensor, SV, water inlet pipe and the central processing unit of being made up of cpu, A/D converter, D/A converter; Gravity sensor is installed under the water pond; And be connected with the input terminus of A/D converter, the output terminal of A/D converter connects cpu; Cpu is connected with SV through D/A converter, and SV is installed on the water inlet pipe, and water inlet pipe one end places the top of water pond, the other end to be communicated with the water source.
Adopt the positively effect of technique scheme: the utility model is introduced automatic water supplementation control system on the cell culture incubator; Moisturizing in the automatic water pond in cell culture incubator timely and appropriately; Solved the artificial problem that is difficult to timely moisturizing and is difficult to accurately control rate of water make-up that moisturizing exists of carrying out, the guarantee of water is provided for the normal growth of cell; The liquid-crystal display that adds in the utility model makes operation more directly perceived.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is system's control chart of the utility model.
Among the figure: 1 cell culture incubator, 2 water ponds, 3 gravity sensors, 4 SVs, 5 cpus, 6 A/D converters, 7 D/A converters, 8 water inlet pipes, 9 water sources, 10 liquid-crystal displays.
Embodiment
Fig. 1 is the structural representation of the utility model; Fig. 2 is system's control chart of the utility model, in conjunction with Fig. 1, Fig. 2 the utility model is described further: the Special Automatic make-up water supply control system of cell culture incubator comprises water pond 2, gravity sensor 3, SV 4, water inlet pipe 8 that places cell culture incubator 1 inside and the central processing unit of being made up of cpu 5, A/D converter 6, D/A converter 7.Gravity sensor 3 is installed under the water pond 2, and is connected with the input terminus of A/D converter 6, and the output terminal of A/D converter 6 connects cpu 5.Like this, after changing into numerary signal through A/D converter 6, the gravitational cue of being experienced by gravity sensor 3 gets into cpu 5.Cpu 5 is connected with SV 4 through D/A converter 7.SV 4 is installed on the water inlet pipe 8 of water pond 2.Top, the other end that one end of water inlet pipe 8 is positioned at water pond 2 are communicated with water source 9.Like this, send after cpu 5 computings and export to SV 4 after instruction changes into simulating signal through D/A converter 7, if gravity value is during less than gravity preset in the cpu; Cpu 5 can start SV 4; In water pond 2, replenish the water source, otherwise, then close SV 4.
For ease of parameter and change parameter are set intuitively, can add liquid-crystal display 10, liquid-crystal display 10 is connected with cpu 5.
During use; The parameter of gravity is set; When the signal of gravity sensor impression during less than normal gravity, lack of water in the water pond be described, cpu can be controlled the SV startup then; When the signal of moisturizing to gravity sensor impression is more than or equal to preset gravity in water pond, stop moisturizing in water pond.Whole process realizes robotization fully, has reduced staff's labor capacity, has also solved artificial carry out moisturizing and have problem untimely and that can't accurately control rate of water make-up.
