[0079] See figure 1 This figure shows a block diagram of a block monitoring device provided in this embodiment.
[0080] In this embodiment, the bed monitoring apparatus, including: transmit antenna 110, the receiving antenna 120, the controller 130, the radio frequency transmit circuit 140, the signal processing circuit 150, and the same polarized reflected radio wave intensity detecting circuit 160.
[0081] It should be noted that in order to avoid the only one thin sheet sheet between the monitoring device and the human body, there is a significant foreign matter in the bed, and to avoid the occurrence of positional part between the body and the mattress in the bed movement in bed. Move, resulting in a low monitoring sensitivity. In the present embodiment, the transmitting antenna 110 and the receiving antenna 120 are placed on the bed and under the mattress. For example, see figure 2 , figure 2 A schematic diagram showing the launching position of the transmitting antenna 110...

[0108] The first embodiment describes a block monitoring device, and the second embodiment will specifically describe how the signal processing circuit extracts the human body reflection signal from the mixing circuit, and how the controller is determined.
[0109] See Figure 6 This figure is a schematic diagram of the signal processing circuit 150 provided in this embodiment.
[0110] In the present embodiment, the mixer 160a is detected in the same polarization reflected radio wave intensity circuit, in the present embodiment, the signal output by the mixer 160a is referred to as a mixed signal. The signal processing circuit 150 provided in this embodiment includes: a first low gain DC amplifier 151 and a first analog to digital converter 152.
[0111] The first low gain DC amplifier 151 is configured to enlarge the DC analog components in the DC signal or low frequency signal; the DC simulation component is a reflected signal as the body.
[0112] Specifically, when the same po...

[0144] The first embodiment describes a bed monitoring apparatus, and the third embodiment will specifically describe how the signal processing circuit extracts a vital sign signal from the mixing circuit, and how the controller judges the bed. vital signs. See Figure 10 This figure is a schematic diagram of the signal processing circuit provided in this embodiment.
[0145] The signal processing circuit 150 provided in this embodiment includes: the discharge circuit 156, the band pass filter 157, and the second analog-to-digital converter 158.
[0146] Wherein, the partial circuit 156 is configured to perform the DC signal or the low frequency signal to the band pass filter 157. It should be noted that the same polarization reflected radio wave intensity circuit in this embodiment is a mixer 160a. Then, the scriptage circuit 156 is specifically used to perform the mixing signals and output to the band pass filter 157.
[0147] It should be noted that in the study, in the study, t...
