Study of bradykinin triggered signal in rat brain microvascular endothelial cell , astrocyte and c6 glioma cells 緩激肽對大鼠腦微血管內(nèi)皮細胞和星形膠質(zhì)細胞及膠質(zhì)瘤細胞影響的體外研究
According to the test conditions , the double polarity inputting mode is adopted in the circuit of voltage - frequency converting part ; storage batteries are used in the optical emission part of optical fibre isolating and transmitting device , that can guarantee isolation between the main circuit and the testing system ; the 89c51 singlechip is used in the singlechip testing - controlling unit , the peripheral circuits are extended , data are transmitted through the serial port in this part ; the p opular software delphi5 . 0 is used in the pc part , the communication between singlechip and pc by serial port , plotting of current wave , regulation of data ; the optical - electrical isolating and triggering are used in the controlling part , this can guarantee the veracity and reliability of breakers triggered , this triggering mode is also used in the triggering of the main closing breaker , the tested breaker and the assistant breaker , the triggering signals are sent out by a singlechip 壓頻轉換部分電路中根據(jù)實際情況采用了雙極性輸入方式;光纖隔離傳輸裝置的光發(fā)射部分電源采用了蓄電池供電,確保了主回路與測試回路的完全隔離;單片機測控部分采用了89c51單片機,擴充了外圍電路,通過串口向pc機傳送數(shù)據(jù); pc機與單片機之間的串口通訊、波形繪制、數(shù)據(jù)管理等都采用了軟件delphi5 . 0編寫。該測試系統(tǒng)中預留了輸出口,可以對合成回路中的主合閘開關、被試開關、輔助開關進行觸發(fā),信號由單片機發(fā)出,控制部分采用了光電耦合隔離觸發(fā)的方法。軟件設計主要集中在對電流信號的數(shù)據(jù)采集、數(shù)據(jù)處理、數(shù)據(jù)傳送、人機界面、波形繪制和數(shù)據(jù)管理,軟件部分又可分為單片機和pc機程序設計兩大部分。
