Problems solved by technology

The existing environmental control system for raising chickens cannot fully meet the needs of chickens. On the one hand, the existing chicken house control system only monitors conventional control quantities such as temperature and humidity, and general ventilation, and does not involve chicken house According to long-term practice, oxygen content has an important impact on the growth, egg production rate and disease resistance of chickens
On the other hand, the existing control controls the temperature and humidity with a single quantity control, causing the temperature to rise and the humidity to drop, or the temperature to drop too fast while strengthening the ventilation, and it is often difficult to balance the two
Furthermore, under normal circumstances, the oxygen content of the atmosphere is about 21%, and this oxygen content is not the best growth environment for chickens; the oxygen content settings of environmental controllers in other fields have problems such as wide ranges and large fluctuations. For those who lack breeding experience, it is easy to miss the best breeding temperature if you set it arbitrarily

Embodiment 1

[0052] To control the temperature in the chicken house at 30°C-31.5°C, start the fan at 33°C and stop at 32°C, control the oxygen content at 19.5%-20.5%, the minimum workload of the fan is 20%, and the temperature is lower than 10°C or higher Alarm at 38°C. Then the implementation steps are as follows:

[0053] The lower limit of oxygen content is 19.5%: code 00 is set to 19.5;

[0054] Oxygen content upper limit 20.5%: It has been cured by the program, no need to set, if necessary, the control program can be modified;

[0055] The minimum ventilation rate is 20%: Code 01 is set to 20;

[0056] The starting temperature of the heating auxiliary machine is 30°C: set the code 70 to 30;

[0057] Heating auxiliary shutdown temperature is 31.5°C: code 71 is set to 31.5;

[0058] The fan is required to start at 33°C and stop at 32°C: code 10 is 1.5, code 11 is 0.5;

[0059] Turn on the set temperature 33-31.5=1.5 ℃

[0060] Shutdown set temperature 32-31.5=0.5℃

[0061] Alarm ...

Embodiment 2

[0065] Oxygen sensor needs to increase the display value by 0.1 due to long-term use of accuracy decline.

[0066] The code 91 is composed of 4 digits. When the thousands digit is 1, that is, "1000" means that the system stops the oxygen content detection; volume compensation setting value.

[0067] The current oxygen content is displayed as 19.5%, and the display value of the oxygen content can be compensated by setting parameters. Generally, when the parameter increases by 1.0%, the displayed oxygen content increases by about 0.1% (non-linear increase). If the set parameter is 1.0 and the displayed oxygen content is 19.5%+0.1%=19.6%, the code 91 is set to 0001.

Abstract

The invention discloses an environment controller for raising chickens and an oxygen detection control method. The oxygen controller jointly controls two parameters, namely, a temperature and an oxygen content, so as to control the operation of an auxiliary heating machine and a fan according to numerical values returned by sensors, so that the temperature and the oxygen content in a closed space are ensured to stay in a set value range. The oxygen content is controlled at 19.5 to 20.5 percent, which is an oxygen content range most suitable for the growth of the chickens.

Description

technical field [0001] The invention is applied to the field of automation control, and relates to an environment controller applied to chicken farms, in particular to an environment controller applied to chicken farms and a detection and control method for air oxygen content. Background technique [0002] In chicken breeding, in order to make it grow rapidly, increase egg production rate, prevent and control diseases, etc., there are often strict requirements on the temperature and air of the breeding environment. In particular, a large amount of ammonia and other harmful gases will be produced in chicken manure, which not only affects the growth of chickens, but may even cause a large number of deaths of chickens, so it is particularly important to detect the air in chicken houses. Ventilation can meet the needs of chickens for oxygen and the elimination of harmful gases, but ventilation should be based on the premise of heat preservation, and at the same time, it is neces...
