多個(gè)信號位于不同廠(chǎng)區，有溫度傳感器的模擬量和氨濃度報警信號，要觀(guān)測運作是否正常，必須得工人時(shí)刻檢測，廠(chǎng)里想改無(wú)線(xiàn)，把信號統一傳到中控室直接檢測不同廠(chǎng)區的情況，問(wèn)一下是否可以實(shí)現

無(wú)線(xiàn)通訊不是很懂，不過(guò)有做過(guò)2種方案，一個(gè)是以太網(wǎng)的wifi無(wú)線(xiàn)，就是2.4G那種，一種是無(wú)線(xiàn)電臺，信號都很容易受環(huán)境干擾，如果只是偶爾數值監控就算斷斷線(xiàn)應該影響也不大，如果對在線(xiàn)監控甚至控制的話(huà)，還是用有線(xiàn)吧
