Notify by text message or alarm through a terminal such as a smartphone, and if you are being damaged by continuous external noise or inter-floor noise, you can receive quantitative data to prove the fact of noise damage, and have an integrity check value In the event that booting and normal operation of the device are impossible due to program damage due to a virus that infects the computer, or if the contents have been altered due to artificial manipulation due to external hackers, it is repaired quickly to overcome the failure and stored in the management server. It relates to a noise data management system using a ceiling-mounted sound level meter that maximizes the reliability of stable security operation and overall system operation.

In general, noise includes inter-floor noise generated inside the house, construction noise generated outside the house, and vehicle noise. In many cases, it is the cause that hinders the comfortable living in the house.

Also, residents living in houses spend most of their time indoors due to COVID-19, and as they spend a lot of time indoors, there is no choice but to generate a lot of noise between floors. Cases of disputes or legal disputes between them are increasing rapidly.

In other words, the noise between floors is a major cause of intergenerational disputes and civil complaints, coupled with the increase in residents' demands for a comfortable indoor environment, and furthermore, frequent casualties occur. Efforts are being made to solve the inter-floor noise problem by strengthening the standards for inter-floor noise blocking performance as well as strengthening the punishment rules for noise damage between floors.

However, as shown in the accompanying drawings, there is a problem in that expensive professional equipment must be used to measure the noise for inter-floor noise and to collect the measured data, and it can only be used for a short, specific time in daily life. There is a limit in that it is not possible to measure various noises appearing in the

In order to solve the above problem, in Korean Patent Registration No. 10-1268318, a noise measuring means and an alarm means are installed in the upper household, and a vibration measuring means is installed between the upper household and the lower household, and environmental data is recorded every selected period. It measures and receives data through wireless communication to sound an alarm when the inter-floor noise exceeds the set value to alert the upper household, but this is a discontinuous alarm system because it measures and gives an alarm at regular intervals. There is a problem in that the accuracy of vibration measurement is lowered as a vibration measurement means of

In addition, in Republic of Korea Patent No. 10-1305138, an alarm is installed in the upper household, and a microphone and a vibration accelerometer are installed between the upper and lower households. It is designed to give a warning and is configured to be able to adjust the number of people during the day and at night, but this has a problem in that there is no scientific and technical research on inter-floor noise and vibration measurement, and there is no limit on the number of alarms and lights. There is a problem in that it is impossible to accurately distinguish vibration and noise with one switch.

As such, the above prior art has a problem in that there is no storage component for storing the measured noise data, so there is no data to be used as reference data when a dispute occurs due to inter-floor noise. There is a problem that it is difficult to come up with a clear rationale.

Accordingly, in order to solve the above problem, Republic of Korea Patent Registration No. 10-1647704 discloses a noise/vibration detection means installed between floors of a two-story house or more to detect noise and vibration, and the noise/vibration detection means detected by the noise/vibration detection means. a data processing device that receives and stores data, and determines whether a detection value exceeds a reference value based on the stored data, and when the detection value exceeds a reference value based on a determination result of the data processing device Since it consists of an alarm means to alert, when the residents of the lower floors are constantly being damaged by inter-floor noise to some extent, quantitative data can be provided to prove the fact of the damage, but the data stored by external factors such as hackers Loss, etc. may occur, which may cause a security problem for the overall data management.

On the other hand, the conventionally implemented technologies consist of measuring only the noise between floors generated in a house, and the noise generated outside the house, that is, noise from a large construction site, noise from a road with a lot of vehicle movement, and external facilities such as a baseball field. There is a problem in that noise generated from noise cannot be measured properly, so it is difficult to prepare clear evidence data to prove the damage in case of an overall noise dispute.

As described above, the conventional monitoring system for noise between floors has a weak security problem. In particular, if booting and normal operation of the device are impossible due to damage to the program executing the data storage, determination and matching units, backup Since there is no function to recover the data, which is the content, or to overcome the failure, it is inevitably vulnerable to security, so there is a problem that the reliability of the overall system operation is lowered.
