Description

Environmental baseline monitor between raising

Technical field

The utility model be a kind of with computer technology to the environmental aspect of pig farm or other raising farm such as temperature, humidity, CO2 concentration etc. detects automatically, the on-the-spot warning etc. that shows, exceeds standard, simultaneously, field data also can send host computer to and carry out data analysis processing, assessment, to reach the system that scientific management is a purpose, belong to the Automatic Measurement Technique field.

Background technology

Change the pig farm on a fairly large scale, all kinds of swinerys all are under the intensity production status, and environmental baseline is very big to its yield-power and health effect.The environmental influence yield-power also influences the height of economic benefit, environmental benefit that Here it is thus.Environmental baseline comprises the harmful gas of producing and storing in climatic environment, stable breeding density, air microbe, the house, dust and management condition etc.

Temperature: pig is a homeothermal animal, and in the ordinary course of things, if the temperature discomfort, the pig body can keep the substantially constant of body temperature by the adjusting of self, but at this moment needs to consume many muscle power and energy, thereby influences the speed of growth of pig.

Humidity: humidity is too high or too low all influential to growing-finishing pig.When hot and humid, pig body heat radiation difficulty, it is sultryyer that pig is felt; When low temperature and high relative humidity, pig body heat dissipation capacity significantly increases, and it is colder that pig is felt, and high humidity environment helps the breeding of pathogenic microorganism, makes pig easily suffer from skin diseases such as mange, eczema.Otherwise, air drying, humidity is low, brings out the breathing problem of pig easily.The suitable relative humidity of pig house is 60-70%.

Harmful gas: because the fermentation or the corruption of fecaluria, feed, pad grass often decompose with toxic gases such as ammonia and sulfuretted hydrogen, and the breathing of pig can be discharged a large amount of carbon dioxide again.If concentration of carbon dioxide is too high in the pig house, can make the anorexia of pig, physique descend, increase weight slowly.

Based on above-mentioned analysis, the real-time monitoring of environment is the urgent current demand of modern large-scale breeding enterprise between realize raising.

The utility model content

Along with science and technology development, especially the widespread usage of single-chip microcomputer and sensor give the pig house environment condition automatically monitoring convenience is provided, the computing machine and the communication technology and development make people implement automatically to the environmental baseline of pig house monitoring, scientific management become possibility.Use this technology, just can directly check each field data, and further analyze, handle, the animal health situation is done further assessment etc., can save manpower like this, reach the purpose of scientific management through system software in the pulpit.

Goal of the invention of the present utility model provides environmental baseline monitor between a kind of raising, and this controller can detect automatically to the temperature between pig house or other animal feeding, humidity and CO2 concentration, the on-the-spot demonstration, and warning etc. exceeds standard; Simultaneously institute is surveyed data and send PC, so that data are made a list, analyze, handled, storage is also made assessment to environmental baseline between raising, to reach the purpose of scientific management.

Environmental baseline monitor between the utility model is raised comprises computer chip (single-chip microcomputer), Temperature Humidity Sensor, CO2 sensor, keypad/display, storer and the parameter warning circuit that exceeds standard; The output of Temperature Humidity Sensor is digital quantity, directly sends into single-chip microcomputer as the input of computer chip, and CO2 data that sensor is surveyed are sent single-chip microcomputer by mould/number conversion circuit (A/D converter) after converting thereof into digital quantity; Single-chip microcomputer is surveyed parameter with institute and is sent display on-the-spot demonstration by the keypad/display interface circuit; Send host computer (10) to by host computer interface circuit (9) simultaneously; Computer chip is surveyed parameter with institute and is sent the memory chip storage respectively, send the parameter warning circuit monitoring alarm that exceeds standard.

The environmental baseline monitor was the cover real-time monitoring system for designing between pig house or other penkeeping between the utility model was raised.The utility model detects automatically to the temperature in the survey environment, humidity and CO2 concentration, the on-the-spot demonstration, and by PC data are made a list, analyze, handled, storage is further made assessment, to reach the purpose of scientific management.This system can augment the detection of some other parameters flexibly according to user's needs.
