WSN (Wireless Sensor Network)-based piggery environment perception electronic nose and working method

Abstract

The invention discloses a WSN (Wireless Sensor Network)-based piggery environment perception electronic nose and a working method; an air chamber is arranged at the upper part; a device protective cover is arranged at the lower part; a sensor device is arranged in the cavity of the air chamber; an air filtering device, a micro air pump, a cleaning air pipeline and a control module are installed in the cavity of the device protective cover; the lower end of the air filtering device is connected to the left end of a horizontally placed cleaning air channel; a horizontally placed hook type spring is arranged in the cavity of the cleaning air channel; the hook at the left end of the hook type spring is fixedly connected to the inner wall of the cleaning air channel; the right end of the hook type spring is connected to an iron sliding block; the right end of the cleaning air channel is respectively connected to the inlet of the micro air pump and the left end of a horizontally placed tested air channel; and an electromagnet wound by a coil is arranged at the left end of the inner cavity of the tested air channel. According to the invention, clear air can be provided for a sensor array; the measurement precision is increased; and real-time monitoring and quality and grade evaluating for the environment condition in a piggery are realized by comprehensively evaluating using multi-parameter through a grade evaluation algorithm.

Description

technical field [0001] The invention relates to a technology for monitoring the environment of pigs, in particular to a device and method for monitoring the air quality in a pig house by using an electronic nose system and a wireless sensor network (WSN). Background technique [0002] The gases in the pig house that have adverse effects on the health and production performance of pigs are collectively referred to as harmful gases. "Environmental Requirements for the Safety, Quality and Pollution-free Livestock and Poultry Meat of Agricultural Products" (GB / T 18407.3-2001) clearly states that ammonia (NH 3 ), hydrogen sulfide (H 2 S), carbon dioxide (CO 2 ) are the three main harmful gases in pig houses. These harmful gases are mainly produced by pigs’ breathing and the decomposition of excrement, feed, bedding, etc., and the content is high in closed pig houses with poor ventilation, humidity, and unreasonable treatment of feces and urine, which will endanger the health o...
