Title:
SENSING SIGNAL RECEIVING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/007446
Kind Code:
A1
Abstract:
Disclosed in the present application are a sensing signal receiving system and method, the system comprising: an interface module, a narrowband frequency selection module, a high-gain amplification module and an in-phase comparison module, wherein the interface module is used for receiving a sensing signal; the narrowband frequency selection module is used for determining, according to a preset receiving frequency, a frequency selection signal in the sensing signal, the frequency of the frequency selection signal being the preset receiving frequency or a narrowband interval comprising the preset receiving frequency; the narrowband frequency selection module is further used for outputting the frequency selection signal to the high-gain amplification module; the high-gain amplification module is used for amplifying the received frequency selection signal, so as to obtain an amplified signal; and the in-phase comparison module is used for converting the amplified signal into a TTL standard signal. The technical solution of the present application can effectively avoid a situation of missed alarm or false alarm of available signals, thus ensuring reliable transmission of sensing signals.
