In　the　process　of　tension　stringing　of　transmission　lines,　the　condition　of　the　plate　needs　manual　reporting,　so　its　safety　is　poor,　and　its　efficiency　is　low.　To　solve　this　problem,　this　study　constructs　a　plate　condition　monitoring　system　of　tension　stringing　based　on　the　LoRa　wireless　transmission.　This　system　consists　of　a　data　acquisition　system,　a　wireless　communication　transmission　system,　and　a　monitoring　and　warning　center.　The　STM32　is　used　to　process　the　data　collected　by　the　sensors,　and　the　LoRa　wireless　communication　system　is　designed　by　way　of　adaptive　dynamic　change　of　LoRa＇s　network　ID,　and　the　networking　mode　of　the　multi-node　relay,　and　the　data　is　sent　to　the　upper　computer　from　a　distance,　and　the　upper　computer　software　is　implemented　by　MFC,　which　can　monitor　the　condition　of　the　plate　in　real-time.　The　test　results　show　that　the　packet　loss　rate　of　LoRa　is　less　than　5%,　and　the　condition　data　of　the　plate　can　be　transmitted　to　the　monitoring　software　through　LoRa　and　displayed.　This　system　has　the　advantages　of　strong　confidentiality,　far　transmission,　and　high　safety,　which　can　be　used　for　real-time　monitoring　of　the　condition　of　the　plate　in　the　process　of　tension　stringing.　　©　Published　under　licence　by　IOP　Publishing　Ltd.
