為解決易燃易爆場合靜電的測試報警問題, 設計了此靜電多路巡檢報警系統. 其硬件部件由傳感器、主控器、顯示器、打印機、報警器5 部分組成. 傳感器采取調制感應式, 并采用鍍膜屏蔽技術, 消除了零漂, 提高了抗干擾能力, 實現了系統的高可靠性、高穩定性和高性價比.
關鍵詞: 調制感應式; 多路巡檢; 實時打印
Abstract: In o rder to so lve the p roblem about test ing and alarm ing of stat ic elect ric in the site w here exp lo re and fire take p lace easily, a mult i2channel stat ic elect ric test ing and alarm ing system has been developed. It’s hardw are consists of five parts, namely, a senso r master tester, disp lay, p rint and an alarm unit, because the senso r w h ich is masked by metal film usesmodulat ing and inducing techno logy, it’s zero offset is re2 duced, its ability of an interference is raised, the design realized the h igh reliability, stability and h igh co st perfo rmance of the system.
