In　the　current　mine　ventilators　monitoring　system,　there　are　some　difficulties　in　the　installation　and　maintenance　because　of　the　wired　connection.　To　solve　the　problem,　this　paper　introduces　a　new　ventilators　monitoring　system　based　on　ZigBee　in　which　the　monitoring　parameters　are　transmitted　wirelessly.　The　collecting　devices　are　designed　to　form　a　cluster　network　to　collect　temperature,　vibration,　air　pressure　and　other　parameters　of　the　mine　ventilator.　All　these　devices　are　battery-powered.　Besides,　the　monitoring　software　in　PC　is　developed　using　MFC.　Experiments　show　that　the　designed　wireless　sensor　network　works　well　in　the　site　environmental　condition　and　the　system　is　very　convenient　to　install　since　the　wireless　connection.　This　monitoring　system　will　have　a　wide　application　prospect　in　the　upgrade　of　the　old　monitoring　system　of　the　ventilators.　©　(2013)　Trans　Tech　Publications,　Switzerland.
