Description

The present invention relates to a construction site monitoring system that measures and records environmental conditions such as vibration and noise generated at a construction site or the like.

At construction sites such as densely populated residential areas due to urban redevelopment, complaints sometimes forced the plan to be changed or suspended.

The complaint information can include the specific content of the complaint in addition to the time and place of occurrence of the complaint.

Here, the "complaint information" can be stored in the complaint information storage unit 50c, for example, by assuming various contents of complaints in advance, classifying them into complaint types, and selecting them so that they can be input.
Specifically, the "complaint information" can be classified into, for example, (1) "vibrating", (2) "noise", and (3) "other" complaint types.
Then, when complaint information is transmitted to the site supervisor of the construction site or other managers by oral, message board, telephone, mail, SNS, FAX, memo, or other direct means switch, etc., from the complaint information input screen (not shown).

The complaint level storage unit 50b divides a plurality of sensor information into a matrix and stores the complaint occurrence management level for each division (hereinafter, appropriately referred to as a complaint level matrix).
That is, the complaint level matrix defines a threshold value (management threshold value, judgment standard) for specifying a complaint occurrence management level corresponding to a plurality of sensor information.
As the plurality of sensor information, the frequency (Hz) and magnitude (dB) of vibration can be used.
For example, in the example shown in FIG. 7, the frequency of vibration is divided into 10 stages and the magnitude of vibration is divided into 11 stages, and the complaint generation management level for each division is stored in the complaint level storage unit 50b.

Specifically, the complaint occurrence management level can be set to, for example, four levels.
In the complaint level matrix in the initial state shown in the upper left of FIG. 7, level 1 of "no response required" is set in the section from the bottom of the vibration magnitude to the 7th stage (55 dB), and the 8th stage of the vibration magnitude. Level 2 of "alert" is set in the (60 dB) and 9th stage (65 dB) sections, and level 3 of "need attention" is set in the 10th stage (70 dB) section of the magnitude of vibration, and the vibration Level 4 of "correspondence required" is set in the eleventh stage (75 dB) of the size.

It is also possible to have a configuration in which the complaint generation management level for each section is stored in the complaint level storage unit 50b.

Further, at this time, in addition to using the complaint level matrix alone, the vibration frequency (Hz), vibration magnitude (dB), sound frequency (Hz), and sound can be used in combination with the vibration level matrix. It is also possible to set the management threshold of the complaint occurrence management level based on the four sensor information of the magnitude (dB).

On the management threshold setting screen, for example, in the complaint level matrix shown in the upper center of FIG. 7, when it is determined that a complaint has occurred due to the vibration of the section indicated by the star, it looks like the complaint level matrix shown in the upper right of FIG. In addition, the complaint generation management level of the complaint generation section has been raised from level 3 to level 4, the complaint generation management level of the lower section has been raised to level 3, and the complaint generation management level of the lower two sections has been raised to level 2. change.

This alert unit can send the above information to the administrator by e-mail or the like.

In this way, by updating the complaint occurrence management level for each section of the complaint level matrix according to the occurrence of complaints, the threshold value for dividing the complaint occurrence management level can be reset according to the passive person such as vibration. Thresholds can be managed in detail, useful information can be obtained to identify the points and causes that need to be dealt with so as not to generate complaints, and complaints can be made by taking measures to eliminate those causes in advance. It is possible to prevent it.
