4, scatol etc., mainly by raising subject breathed, fecaluria, feed is corrupt decomposes and produce.Harmful gas increased content in feed lot house, has bad impact to raising health and the yield-power of object, and harmful gas very Gao Shike causes that raising object is poisoning, even dead.
Document " nuclear electronics and Detection Techniques " the 26th volume the 6th phase < < nuclear radiation and monitoring harmful gases instrument design > > mono-literary composition disclose a kind of monitoring harmful gases instrument consisting of MCU and various harmful gas sensors etc., for each toxic gas, all be provided with the corresponding chemical sensor of a set of special use, and these special chemical sensors are expensive, serviceable life is short, thereby equipment investment cost is high, causes and fail large-scale promotion application always.
Hen house monitoring harmful gases system > > mono-literary composition of document " agricultural research " the 4th phase < < in 2011 based on AVR single-chip microcomputer discloses the monitoring harmful gases system of a kind of ammonia, sulfuretted hydrogen or carbon dioxide, for each toxic gas, equally the corresponding detecting sensor of a set of special use need to be set respectively, input cost is naturally also higher.
Chinese invention patent 201110136466.0 discloses a kind of chemical industrial park toxic and harmful detection system, it comprises sensor node, gathers base station and Surveillance center, detection module in sensor node comprises concentration of hydrogen sulfide transmitter, sulfur dioxide concentration transmitter, chlorine gas concentration sensor, for each toxic gas, it also needs to arrange respectively a set of specialized equipment, cost is still higher, promotes difficulty large.
Summary of the invention
The above-mentioned defect existing in order to overcome prior art, the invention provides a kind of low cost of manufacture, feed lot house monitoring harmful gases system and method applied widely.
According to Avogadro (Ameldeo Arogadro 1776～1856, Italian natural scientist) law: at identical temperature and pressure, any gas of same volume all contains the molecule of similar number.Inside and outside feed lot house, always there is window to communicate with atmosphere, that is to say, air pressure in feed lot house is also an atmospheric pressure, the temperature of feed lot house is also the scope of a relative narrower of 10～35 ℃ of requirements, therefore, and the applicable Avogadro law of feed lot house gas.Like this, we just can infer by the content of this gas of monitoring oxygen the total content of harmful gas in feed lot house.
Technical scheme of the present invention is:
The system of the present invention's feed lot house monitoring harmful gases comprises control center, control center is connected with communication module is two-way, communication module is connected with central processing unit is two-way, central processing unit is connected with storer is two-way, central processing unit is connected with front end circuit module is two-way, oxygen sensor or unidirectional be connected two-way with front end circuit module.
Further, described central processing unit is flush bonding processor.
Further, central processing unit is also connected with Temperature Humidity Sensor is two-way by another front end circuit module.
Further, described control center can be combined in central processing unit, directly by central processing unit, realizes the control of various functions.
Further, described control center can replace with intelligent scavenger fan, and intelligent scavenger fan is directly connected with flush bonding processor.
Two-way or unidirectional connection between described oxygen sensor and front end circuit module, depend on whether oxygen sensor itself has needs, whether likely from front end circuit module, obtains order, whenever necessary, oxygen sensor is connected with front end circuit module is two-way, not whenever necessary, oxygen sensor is connected with front end circuit module is unidirectional.
Further, described oxygen sensor can substitute with nitrogen sensor.Because of in air, surpass 70% be nitrogen, therefore also can infer the total content of harmful gas in feed lot house by the content of this gas of monitoring nitrogen, just nitrogen sensor is slightly higher than oxygen sensor cost.
The present invention's feed lot house monitoring harmful gases method, step is as follows: oxygen sensor detects the content of oxygen in feed lot house, by oxygen content, infer the content of harmful gas in feed lot house, and sending monitoring result to information control center, control center takes corresponding treatment measures according to default threshold value after analyzing monitoring result.
The present invention is by reaching the monitoring objective to feed lot house harmful gas to the monitoring of pure gas (as oxygen or nitrogen), in actual applications, (unit price of oxygen sensor is generally 1000 yuan of left and right not only to have reduced application cost, the sensor unit price of other harmful gases is general over 2000 yuan), (life-span of oxygen sensor is 5～10 years also to have extended the Acceptable life of monitoring system, the sensor life-time of other harmful gases was generally about 2 years), work efficiency is high, to increasing performance of enterprises successful.
The present invention is simple in structure, and functional reliability is high, and energy consumption is low.
