机器进入工作状态后,冷源电路和通道电路工作正常,而改在热源电路工作时,PC机报警放射源到位失灵故障,所选通道治疗导管插上和拔掉,现象不变。通常是检测热源钢丝到位的光电耦合器V_0错位或耦合孔堵塞,控制电路得不到光电指令信号所致。我们改变常用的拆钢丝套管,拉出钢丝,同时谨防拉出热源,调校等繁琐步骤,采用使
After the machine enters the working state, the cold source circuit and the channel circuit work normally, but when the heat source circuit works, the PC alarm radiation source fails in place, the selected channel treatment catheter is plugged in and unplugged, and the phenomenon remains unchanged. It is usually detected that the optocoupler V_0 of the heat source wire is in position or the coupling hole is blocked, and the control circuit cannot obtain the photoelectric command signal. We changed the commonly used wire-removing wire bushings, pulled out the wire, and at the same time guarded against pulling out the heat source, adjusting and other cumbersome steps, using
