The active and standby detectable signal processing unit of embodiment is detected to nuclear power station main pump rotating speed and to detecting the detectable signal obtained
Carry out independent process and transmission, i.e. main probe and standby probe for being detected to nuclear power station main pump rotating speed are detected and obtained
Detectable signal enter before the processor of nuclear power station main pump rotating speed frame, main detectable signal and the standby probe of main probe output
The standby detectable signal of output is separate, and is independent of each other, and any interference is not present in each comfortable transmitting procedure, tradition is solved
The main probe of frame and the standby interference problem popped one's head in and existed when altogether.As shown in figure 1, the active and standby detectable signal processing dress of the present invention
The main probe putting including collection nuclear power station main pump rotating speed to export main detectable signal and gather the nuclear power station main pump rotating speed with
The standby probe of the standby detectable signal of output, in addition to input module 10, transport module 20, control module 30, signal processing module
40th, main control module (not shown).Control module 30 is controlled by main control module output control signal, made at transport module 20 and signal
Manage the correspondence of module 40 to connect, main detectable signal and/or standby detectable signal are transmitted to signal processing module 40, by signal transacting
40 pairs of main detectable signals of module and/or standby detectable signal are individually handled.
Specifically,
