The invention provides a printed circuit board with an integrated alarm function. The printed circuit board comprises at least two PCBs which are in circuit connection; at least one solid-state relay group is arranged on each PCB and is used for carrying out logic processing on the alarm signal; the control signal receiving port and the control signal transmitting port are arranged on each PCB and are respectively connected with the receiving end and the output end of the solid-state relay group; each PCB is in communication connection with a fault signal lamp, a scintillation relay and a buzzer. After the solid-state relay group receives a first alarm signal through the control signal receiving port, the first alarm signal is logically processed by the solid-state relay group to generate a second alarm signal, and the second alarm signal is output through the control signal sending port; and the second alarm signal controls the fault signal lamp to light and triggers the scintillation relay and the buzzer to work. The device has the advantages of being simple and compact in structure, good in use stability, good in data transmission capability and capable of effectively improving the alarm efficiency.
本发明提供一种带有集成式报警功能的印制线路板,其包含:至少两个电路连接的PCB板;每个PCB板上设置有至少一组固态继电器组,用于对报警信号进行逻辑处理;设置在每个PCB板上的控制信号接收端口和控制信号发送端口,其分别与固态继电器组的接收端和输出端连接;每个PCB板分别与故障信号灯、闪烁继电器和蜂鸣器通信连接;当所述固态继电器组通过控制信号接收端口接收到第一报警信号后,第一报警信号经过固态继电器组的逻辑处理生成第二报警信号,通过控制信号发送端口输出第二报警信号,所述第二报警信号控制故障信号灯亮光、以及触发闪烁继电器和蜂鸣器工作。本发明具有结构简单紧凑,使用稳定性好,数据传输能力好,可有效提高报警效率的优点。
