Acoustic sensor system
A sensor system can include a sensor module including a vibration sensor; a processor module including a power supply and a processor PCB, the processor module connected in electrical communication with the sensor module by a first cable; and an antenna module including an antenna, the antenna module connected in electrical communication with the processor module by a second cable.
1 . A sensor system comprising:
a sensor module comprising a vibration sensor;
a processor module comprising a power supply and a processor PCB, the processor module connected in electrical communication with the sensor module by a first cable; and
an antenna module comprising an antenna, the antenna module connected in electrical communication with the processor module by a second cable;
wherein:
the sensor module further comprises a sensor enclosure shell and a fastener;
the vibration sensor is positioned within a sensor cavity defined by the sensor enclosure shell;
the fastener extends through the sensor enclosure shell; and
the vibration sensor is mounted to the fastener.
2 . The sensor system of claim 1 , wherein:
the processor module further comprises a processor enclosure;
the processor enclosure comprises a container shell and an insert; and
the processor PCB is secured to the insert.
3 . The sensor system of claim 1 , wherein:
the sensor module further comprises a magnet.
4 . The sensor system of claim 3 , wherein the magnet is positioned within the sensor cavity.
5 . The sensor system of claim 4 , wherein:
the vibration sensor defines a threaded portion;
the threaded portion extends through the magnet and is coupled to the sensor enclosure shell; and
the vibration sensor secures the magnet to the sensor enclosure shell.
6 . The sensor system of claim 3 , wherein the magnet is secured to the fastener.
7 . The sensor system of claim 1 , wherein the sensor module, the antenna module, and the processor module are each hermetically sealed.
8 . The sensor system of claim 1 , further comprising a vault with a lid, the vault defining a vault cavity, the lid at least partially enclosing the vault cavity, the antenna module positioned within the vault cavity and secured to the lid by an antenna mount.
9 . The sensor system of claim 1 , further comprising a vault buried at least partially beneath a ground surface, the vault defining a vault cavity, the processing module positioned within the vault cavity, the antenna module positioned within a hole extending into the ground surface, at least one cable connecting the antenna module in electrical communication with the processing module.
