Hog house gas detection alarm system and method

Abstract

The invention relates to a hog house gas detection alarm system and a method thereof. The system comprises a wall body, a top cover, lighting and ventilating windows, a colony house and supporting beams. Monitors are fixed at four corners of the wall body; the monitors are connected with a master control system module; the master control system module comprises a monitoring module used for monitoring behaviors and sounds of pigs, a behavior analysis module and a sound processing module which acquire the pig cough condition in the pig house, an image processing module which analyzes abnormal behaviors of the pigs, a gas detection module which detects the gas concentration of the colony house, an alarm module which controls a NH3 alarm lamp and a CO2 alarm lamp, an atomization module which sprays atomized water vapor to absorb toxic gas and cool the pig house at the same time, a telescopic module which controls a first electric telescopic rod to ascend and descend the pig house for ventilation and controls a second electric telescopic rod to ascend and descend the gas monitor so that the gas generation position can be accurately determined, and a fan module which controls an exhaustfan to be turned on and the power of the exhaust fan to realize effective ventilation and energy conservation.

Description

technical field [0001] The invention relates to a pig house gas detection and alarm system and a method thereof, belonging to the technical field of gas alarm. Background technique [0002] With the improvement of people's living standards, the demand for the quality of livestock and poultry meat is also increasing. At present, the output value of pig breeding accounts for 64.1% of the total output value of livestock and poultry, and pig breeding has become a pillar industry of my country's breeding industry. The domestic pig breeding industry is different from foreign countries. According to China's national conditions, the breeding land is becoming increasingly tight, but the environment distribution of pig houses in different regions, different seasons, and different growth stages is quite different. Especially in the northern region, ventilation is reduced for internal heat preservation in winter. It is easy to cause harmful gases in the house to exceed the standard, wh...

The domestic pig breeding industry is different from foreign countries. According to China's national conditions, the breeding land is becoming increasingly tight, but the environment distribution of pig houses in different regions, different seasons, and different growth stages is quite different. Especially in the northern region, ventilation is reduced for internal heat preservation in winter. It is easy to cause harmful gases in the house to exceed the standard, which seriously affects the growth and development of pigs, average daily weight gain and reproductive performance. In summer, pig houses are caused by high stocking density and poor ventilation. The temperature continues to increase, the humidity drops, and the pigs have obvious heat stress Stress reaction, etc.; the quality of the internal environment of the pig house directly affects the production efficiency of the breeding industry

When NH in the pig house 3 When the concentration is high, pigs will have symptoms such as coughing, ear biting and tail biting. CO 2 Pigs will appear restless, fight and other phenomena at a higher time, seriously affecting the quality of pigs

[0003] The traditional manual on-site measurement of the environment in the pig house is difficult to measure at multiple points at the same time, because the movement of people will cause the pigs to move around and the detection is inaccurate; another kind of people will install gas detection alarms in the pig house, but the gas Due to the difference in density and the uneven distribution of gas concentration, the installation position of the detector is very important, which is related to the accuracy of the detection data; the higher installation position is inaccurate for carbon dioxide detection, and the lower is because there are many pens in the pig house, it is installed in a small Outside the pen, the space is narrow and the detection data is inaccurate. If it is installed near the pen, it is easy to be eaten by pigs and cause damage to the detection equipment. At the same time, a larger pen needs to install more gas detectors to effectively detect the pig pen. Accurate monitoring of internal gas, waste of resources and inaccurate data due to environmental instability
