Lamp bell alarm system state detection circuit for irradiation accelerator

The invention discloses a lamp bell alarm system state detection circuit for an irradiation accelerator, a lamp bell alarm system comprises a lamp bell, the detection circuit comprises an on-off signal detection conversion unit, and the on-off signal detection conversion unit is arranged in a power supply loop of the lamp bell. And the on-off signal detection conversion unit is used for sending the on-off state of the lamp bell power supply loop to a corresponding detection port of the main control system through the state output terminal after isolation conversion. The alarm lamp load detection circuit has the advantages that the voltage drop of the diode can be kept constant under the condition of different currents in a loop, the alarm lamp load detection circuit can adapt to detection of various alarm lamp loads and can output the working state of a lamp bell in cooperation with the optocoupler, and rapid and reliable detection of the working state is achieved. 本发明公开了一种辐照加速器用灯铃报警系统状态检测电路，所述灯铃报警系统包括灯铃，所述检测
