Sound inspection system and sound inspection method
A sound inspection system that can reduce power consumption is provided. A sound inspection system 1 that determines a state based on a sound of an inspection target object 2 includes a sound sensor device 10 that collects the sound of the inspection target object 2 , analyzes the collected sound, and transmits an analysis result, and a sound data determination device 30 that determines a state of the inspection target object based on the analysis result from the sound sensor device. The sound sensor device transmits, as the analysis result, intensities of the collected sound for each predetermined frequency set in advance.
1. A sound inspection system that determines a state based on a sound of an inspection target object, the sound inspection system comprising:
a sound sensor device that collects the sound of the inspection target object, analyzes the collected sound, and transmits an analysis result; and
a sound data determination device that determines a state of the inspection target object based on the analysis result from the sound sensor device,
wherein the sound sensor device transmits, as the analysis result, intensities of the collected sound for each predetermined frequency set in advance, and
wherein the sound sensor device further includes a power generation unit that converts the sound or a vibration of the inspection target object into power.
2. The sound inspection system according to claim 1 , wherein the sound sensor device determines whether or not the collected sound is classified into any onomatopoeia of predetermined onomatopoeias prepared in advance by analyzing the collected sound for the predetermined frequency, and transmits a classification result as the analysis result.
3. The sound inspection system according to claim 1 , wherein the sound sensor device further includes an alert unit that outputs an alert according to an instruction from the sound data determination device.
4. The sound inspection system according to claim 1 , wherein the sound sensor device is connected so as to be able to wirelessly communicate with the sound data determination device via a wireless master station.
5. The sound inspection system according to claim 1 , wherein the sound sensor device is powered by a built-in battery.
6. A sound inspection method for determining a state based on a sound of an inspection target object, the sound inspection method comprising:
transmitting, as an analysis result, intensities of collected sound for each predetermined frequency from a sound sensor device that collects the sound of the inspection target object to a sound data determination device; and
determining, by the sound data determination device, a state of the inspection target object based on the analysis result received from the sound sensor device,
wherein the sound sensor device transmits, as the analysis result, intensities of the collected sound for each predetermined frequency set in advance, and
wherein the sound sensor device converts the sound or a vibration of the inspection target object into power.
