Description

  The present invention relates to an environmental information monitoring management system that acquires environmental information of an area to be monitored, and monitors or presents the acquired environmental information.

  Conventionally, as disclosed in Patent Document 1, for example, it is installed at a construction site, and automatically measures noise level and vibration level at the same time, displays the result in a graph or the like, or emits a warning lamp in real time. A noise and vibration measurement and monitoring device that can inform neighbors has been proposed.

  Further, in Patent Document 2, a noise level meter and / or a vibration meter are arranged at least at three or more points within a construction site or a range including the vicinity thereof, and these noise level meter and / or vibration level meter are installed in a computer. The noise and / or vibration data measured by each sound level meter and / or vibration meter is acquired, and compared with the noise and / or vibration management value, the measurement noise and / or vibration level is a management value. If the warning level exceeds the required level, the noise and / or vibration generation position is identified based on each measured noise and / or measured vibration data, and the noise is detected within the construction site or a specific worker (for example, heavy machinery). A noise / vibration monitoring and reduction method is described in which a warning that noise and / or vibration is above a predetermined level is issued to an operator or the like.

  In Patent Document 3, a plurality of sound level meters are arranged in a construction site, and measurement data of the sound level meters are transmitted to a base station (central computer) via a mobile phone network. Based on the transmitted noise data, the noise on the boundary line at the construction site is calculated, and when the noise exceeds a predetermined threshold, an instruction is transmitted to a predetermined construction machine via the mobile phone network. A noise reduction system that performs processing such as switching the mode to a low noise mode is described. In addition, there is a description of a dialogue board for the base station (central computer) to publish the noise level at the construction site to the surrounding residents along with the schedule through the Internet.

  In Patent Document 4, various environmental data such as noise, vibration and other environmental data including noise at various civil engineering construction sites and building construction sites, and raw images of the site are comprehensively collected and monitored accurately. It describes a sound and image measurement and monitoring system for environmental data. Further, Patent Document 4 shows, as environmental data to be measured, vibration, dust, water level, turbidity, temperature, humidity, light quantity, wind direction, wind speed, sunshine, ultraviolet light, rainfall, odor, etc. of the place to be measured. Yes.

  However, the thing of patent document 1 measures noise and vibration in the temporary enclosure position near the site boundary of a construction site, for example, and notifies the result to the neighborhood person. There is a fact that it is difficult to grasp.

In addition, since it is difficult for managers and heavy equipment operators who are away from the installation location to know the measurement results in real time, if the noise or vibration exceeds the allowable value, There is a time lag before we know that. For this reason, it is impossible to know in real time how much noise or vibration is occurring during work, and it can only be dealt with after the noise and vibration exceed the allowable value. There is a situation that it is difficult to take some measures before exceeding the limit to prevent noise and vibration from exceeding allowable values.
In addition, what is described in Patent Document 1 is only displayed as a numerical value, and how much noise and vibration are generated with respect to an allowable value while an administrator or a heavy equipment operator is working. There is a situation that it is difficult to grasp about instantly.

  The device described in Patent Document 2 can issue warnings to managers and heavy equipment operators when noise or vibration exceeds the level during work, but sound level meters, vibration meters, warning lights, etc. are wired. Since it is connected to a computer via a network, it is not easy to use because there are restrictions on the installation location, and a monitoring computer in the construction site office is connected to the computer via a wired or wireless LAN (Local Area Network). For example, there is a situation that noise data and vibration data cannot be seen in a place away from the construction site. In addition, it is difficult for managers and heavy equipment operators to adjust the work content as appropriate within a range where noise and vibration do not increase because the noise and vibration level generated during work cannot be known in real time. There is a real situation.

The one described in Patent Document 3 transmits the measurement data of the sound level meter to the base station (central computer) via the mobile phone network, while the base station (central computer) processes the transmitted noise data, When the noise exceeds a predetermined threshold, an instruction can be transmitted to a predetermined construction machine via the mobile phone network, and the base station (central computer) is connected to the internet via the interactive board Therefore, the noise level at the construction site can be announced to the residents along with the schedule, but the only environmental information handled is noise.
Moreover, in the thing of patent document 3, the measured noise data is once sent to a base station (central computer) via the Internet, and after performing various processes there, it is predetermined | prescribed via a mobile telephone network. Since the instruction is transmitted to the construction machine, there is a time lag from when the noise is generated and measured until the construction machine actually receives the instruction. Furthermore, there is room for improvement regarding the method and system configuration for presenting noise data, and it is required that the user be more user-friendly.

  Although the thing of patent document 4 monitors various environmental data, it is not realistic to measure and monitor all these environmental information, and it is realistic in the civil engineering construction site, the building construction site, etc. It is considered desirable for users to measure and monitor the required environmental data from the viewpoint of cost, installation space, and the like.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments described below.

  In the environmental information monitoring and management system according to an embodiment of the present invention, as shown in FIGS. 1 to 3, a measuring instrument (vibration meter, noise meter) is provided at a predetermined measurement point in a civil engineering work site or a construction site. Measuring units (sub-measuring devices) 1A to 1C containing dust meters, anemometers, anemometers, thermometers, hygrometers, etc.) are disposed, and environmental information at each measurement point via the measuring units 1A to 1C. (Vibration, noise, dust, wind direction, wind speed, temperature, humidity, etc.) are automatically acquired at predetermined time intervals (for example, every 1 second).

  As a sound level meter, for example, “NL-21” manufactured by Lion Co., Ltd., for example, “VM-53A” manufactured by Lion Co., Ltd., as a dust meter, for example, “LD-3K2” manufactured by Shibata Kagaku Co., Ltd., as a temperature / hygrometer For example, “HD 9809T” manufactured by Delta Ohm Co., “PGWS-100” manufactured by PREDE Co., for example, as a wind direction / anemometer, “WBGT display” manufactured by Tsuruga Electric Co., Ltd. as a WBGT meter Can be used.

  The environmental information acquired by the measurement units 1A to 1C is a recording arithmetic processing device (PLC: Programmable Logic Controller, hereinafter referred to as PLC) via wireless (wireless LAN, mobile phone network, etc.) or PLC (Power Line Communication, etc.). Is transmitted to a master measurement unit (main measurement device) 2 provided with the recording calculation processing device), and the master measurement unit 2 sends the received environmental information to the PLC in correspondence with the measurement point and the measurement time. Record.

By the way, the master measuring unit (main measuring device) 2 is also provided with measuring instruments (vibration meter, noise meter, dust meter, anemometer, anemometer, thermometer, hygrometer, etc.), and the master measuring unit (main measuring device). ) Environmental information (vibration, noise, dust, wind direction, wind speed, temperature, humidity, etc.) at the point where 2 is arranged can be automatically acquired at predetermined time intervals and recorded on the PLC. ing.
Here, the accommodated measurement units (sub-measurement devices) 1A to 1C and the master measurement unit (main measurement device) 2 correspond to the environment information acquisition device according to the present invention. The master measurement unit (main measurement device) 2 functions as an environmental information management device according to the present invention.

  The master measuring unit 2 includes a monitor (heavy equipment monitor) 3A for an operator seat of a heavy machine (work machine) 3 in a construction site, a display monitor (information monitor) 4 provided in a temporary enclosure that defines the construction site and the neighborhood. The environment information is transferred in real time via a wireless (wireless LAN, mobile phone network, etc.), and the heavy equipment monitor 3A and the display monitor 4 are configured to display the received environment information on the browsing screen. The monitor (heavy equipment monitor) 3A and the display monitor (information monitor) 4 correspond to the information browsing apparatus according to the present invention. By the way, as heavy machinery, mobile power machines such as power shovels, bulldozers, cranes, etc. used in civil engineering and construction work are equivalent.Work machines include these, as well as smaller machinery and This includes civil engineering and construction machinery with noise and vibration, such as stationary boring machines.

  Further, as shown in FIG. 3, the master measuring unit 2 is configured to be capable of bidirectional communication with, for example, a PC (personal computer) in the management office 10 at the construction site via the Internet. In the PC in the office 10, the measurement units (sub-measurement devices) 1 </ b> A to 1 </ b> C and the master measurement unit (main measurement) arranged at each measurement point in the construction site transmitted from the master measurement unit (main measurement device) 2. The measurement data of the environmental information of the apparatus 2 is unified, and a list can be displayed on the management monitor screen using, for example, a graph, a table or the like as shown in FIG. The PC in the management office 10 corresponds to an information browsing apparatus to which information is transmitted via the Internet according to the present invention.

The PC in the management office 10 stores the measurement data in association with the time, and summarizes the wind direction, wind speed, temperature, humidity, etc. along with the noise, vibration, and dust data for each day or time. A report (see, for example, FIG. 5) or the like can be created and output.
Further, since the master measuring unit 2 is connected to the Internet, environmental information and the like can be obtained from a plurality of locations (for example, the head office, design offices, neighboring houses, etc.) apart from the construction site other than the management office 10. Can be monitored.

  By the way, in the present embodiment, measurement data of environmental information such as noise, vibration, and dust is directly transmitted to the monitor 3A of the operator seat of the heavy machinery 3 by the master measurement unit 2 without using an administrator or the like. For example, as shown in FIG. 6, the monitor 3A in the operator seat of the heavy equipment 3 transfers such measurement data to the drawing browsing software executed by the processing unit provided in the monitor 3A. It is designed to display in real time in the display format. For this reason, the heavy equipment operator can know environmental information in real time, and can recognize environmental information such as noise generated in response to work without time lag.

  Further, as shown in FIG. 6, the monitor 3A for the operator seat of the heavy equipment 3 provides measurement data related to the environmental information as shown in FIG. 6 so that the heavy equipment operator who is concentrated in the work can quickly and accurately grasp the environmental information. It can be displayed in a bar level display. That is, on the screen of the monitor 3A, the real-time noise level, vibration level, and dust level measured at each measurement point (shown as A, B, C, and D in FIG. 6) are displayed by the level bar. At the same time, allowable values (allowable levels) of noise, vibration, and dust level are displayed on the same screen corresponding to each.

  Therefore, even heavy equipment operators who are working can easily and accurately grasp how much tolerance is available in real time, so that heavy equipment can be used so that noise, vibration, and dust levels do not exceed the tolerance values. Therefore, it is possible to effectively suppress the possibility that the operation of the heavy machinery operator is delayed and the noise, vibration, dust level and the like exceed the allowable values.

  In the present embodiment, the permissible values of noise, vibration, and dust level are displayed at substantially the same level (see FIG. 6) so that the margin of the measured value with respect to the permissible value can be grasped at a glance. The display has been adjusted.

  In addition, for example, by displaying the allowable values of noise, vibration, and dust level with red lines, etc., and displaying the level bar of the measured values with green etc., the current noise, vibration, The dust level can be recognized more quickly and accurately.

  Furthermore, when the measured value approaches the allowable value, the level bar color is changed from green to yellow, for example, and the display blinks to alert the heavy equipment operator, and the measured value exceeds the allowable value. In such a case, for example, if the configuration is made so that the heavy equipment operator can be surely recognized that the warning has occurred by changing the color from yellow to red and blinking the display, the heavy equipment operator will further increase the current The noise, vibration and dust level can be recognized quickly and accurately.

  The display form of the display screen of these monitors 3A may be configured in a drawing browsing software setting screen (for example, in a touch panel format) executed by the arithmetic processing unit provided in the heavy equipment monitor 3A as shown in FIG. Can be changed as appropriate.

  Here, in the present embodiment, just by displaying on the browsing screen of the heavy equipment monitor 3A, the recognition of the heavy equipment operator who concentrates on the work is delayed, or the heavy equipment monitor 3A is distracted and adversely affects the operation of the heavy equipment 3. In order to suppress such fears, considering at least one of boom 3B, arm 3C, and various attachments (buckets, etc.) 3D of heavy equipment 3 shown in FIG. For example, a caution warning lamp that lights or flashes in two stages of caution / warning is attached, and when a caution or warning is required, the caution warning lamp is lit or flashes to improve visibility and cognition, and heavy equipment operators It is possible to reliably recognize the occurrence of attention or warning.

In addition, the heavy equipment operator masters a signal and / or a comment, a message, etc. indicating that a warning warning has been recognized by pressing an appropriate area on the browsing screen of the touch panel type monitor 3A or an individual operation button. It can be configured to be able to transmit to the measurement unit 2 or a PC in the management office 10.
As a result, not only the warning information can be notified to the heavy equipment operator in one direction, but also the administrator can receive a response from the heavy equipment operator. For example, even if the warning warning lamp is lit or blinking It is possible to immediately recognize a situation where the heavy machinery operator is not aware of it, and to take a quick response accordingly.

  When a plurality of heavy equipments 3 are operating, each heavy equipment 3 is individually provided with a monitor 3A. Therefore, when displaying environmental information and other warning information sent in real time, the heavy equipment 3 The display form and the like can be appropriately changed every time through the settings of the drawing viewing software, which is convenient for the user.

  Thus, for example, when a heavy machine (or any one of a plurality of heavy machines) performs work near the site boundary, the tolerance value at the measurement point close to the work point by the heavy machine operator or manager. As a result, it is possible to effectively prevent the occurrence of complaints from residents in the vicinity by setting the display conditions for warnings and warnings of the heavy equipment monitor 3A. It becomes possible.

  Here, not only the heavy equipment monitor 3A and the caution warning lamp are to be notified by the master measurement unit 2 but also other monitors such as a PC monitor (viewing) in the management office 10 at the construction site. Screen) via a drawing browsing software.

  Specifically, the measured value related to the environmental information is indicated as “CAUTION” before the predetermined allowable value exceeding the predetermined allowable value set in advance, and “WARNING” when the measured value exceeds the predetermined allowable value. While the target part is turned on or blinked, for example, an alarm is sounded at the same time. The alarm is not limited to a warning sound such as a buzzer or a siren, but can be a voice or a vibrator. Such a display or warning can be continued for a predetermined time after being issued, or until it is instructed to be released by a heavy equipment operator or a manager.

  Here, the determination of “attention” and “warning” is, for example, when the measurement time interval is 1 second, the past 100 pieces of measurement data that exceeds an allowable value (for example, the noise level is 85 dB) is a predetermined threshold value. (For example, 3 (total time: 3 seconds)) is determined to be “Caution (yellow)”, and the past 100 pieces of measurement data that exceed the allowable value are set to a predetermined threshold (for example, 5 (5 seconds in total time)) is exceeded, “warning (red)” determination is made. Therefore, in the present embodiment, when the measurement time interval is 1 second, measurement data for the past 100 seconds is stored. The predetermined threshold value, display color, and the like can be set as desired according to demand.

  More specifically, the PLC included in the master measurement unit (main measurement device) 2 according to the present embodiment includes environmental data (noise, vibration, dust data, etc.) for the past 100 seconds as shown in FIG. Are stored in association with the time when the environmental data is acquired.

  In the master measurement unit (main measurement device) 2, as shown in FIG. 9, for example, in the case of noise data, a new noise is generated every second when the measurement time interval is 1 second with reference to the noise level. Each time data is input, the noise data is sorted according to the noise level, and the number of data exceeding the allowable value is counted. Further, in the master measurement unit (main measurement device) 2, when the measurement time interval is 1 second with reference to the time data, the time data of the oldest time is input every time new noise data is input every second. And the noise data corresponding to this are deleted.

  As a result, the master measurement unit (main measurement device) 2 monitors environmental data for the past 100 seconds from the present, and issues signals such as cautions and warnings to the heavy equipment monitor 3A, the PC in the management office 10, and the like. Will be able to.

Here, the noise level and the vibration level may be obtained by calculating the Lx value for 10 minutes every 10 seconds. Lx value is a method of measuring and evaluating continuously fluctuating data and is called a time rate level. Data is continuously acquired at a certain time interval, and as shown in FIG. If ordered to a small value from a large value, referred to the value of 5% th from the largest L ₅ value, the value of 10% th and L ₁₀ value. For example, in the Noise Regulation Law, L ₅ value, L ₁₀ value is employed in the vibration regulating method. Therefore, also in this embodiment, the L ₅ values, seeking L ₁₀ value, it is possible to evaluate the noise and vibration.

However, the empirically by the method described in FIG. 9, the L ₅ values, it is can be substituted in L ₁₀ value. That is, the L ₅ value corresponds to the case where that exceeds the allowable value of the past 100 measurement data becomes five, the L ₁₀ value, the allowable value of the past 100 measurement data It can be handled as equivalent to the case where the number of items exceeds ten.

  By the way, the master measurement unit (main measurement device) 2 transfers environment information in real time to a display monitor (information monitor) 4 provided in a temporary enclosure or the like that defines the construction site and the vicinity. The display monitor (information monitor) 4 is installed in a place that is easy to see for the surrounding residents, such as along the road, and is appropriately displayed according to the selection of the viewer as shown in Display Example 1 and Display Example 2 shown in FIG. Can be switched, and it is also possible to display a list of environmental information of the entire construction site.

  The display monitor (information monitor) 4 can be configured, for example, in a touch panel format, and the surrounding residents who operate can access and browse environmental information that they want to know in real time, for example, in a dialog format. Can be configured as follows. In addition, the display monitor (information monitor) 4 can display management information (for example, a construction schedule or a message) via a wireless LAN or the like from a PC or the like in the management office 10. Information displayed on the display monitor (information monitor) 4 can be rewritten from a PC or the like in the management office 10.

  Here, the outline of several processes performed in the environmental information monitoring management system according to the present embodiment is summarized in FIG.

As shown in FIG. 12, in the PLC of the master measurement unit (main measurement device) 2 (corresponding to point A in FIG. 12) according to the present embodiment, measurement units (sub-measurement devices) 1A to 1C (in FIG. 12) , Corresponding to the point B to the point D), data related to the environment information measured is received, and the following processing is performed.
(1) The current value (measurement data corresponding to the measurement time, in other words, “real time data”) at each point A to D is stored every second.
(2) For noise and vibration data, the Lx value for the past 10 minutes is calculated every 10 seconds based on the current value.
(3) For dust data, an average value for the past 10 minutes is calculated every 10 seconds based on the current value.

In the PC in the management office 10, for example, the following arithmetic processing, display, or processing for creating a report is performed.
(4) The Lx value of each measurement data when connected to the master measurement unit (main measurement device) 2 and the maximum value of the day are displayed.
(5) For the graph, the maximum value every 2 minutes up to 12 hours ago is displayed.
(6) About noise and vibration data, it divides for every 10 minutes (600 pieces) of measurement data, and calculates | requires Lx value for every area by calculation.
(7) For noise and vibration data, a graph is drawn with the above-mentioned Lx value as the vertical axis and time-dependent elements such as date and time as the horizontal axis.
(8) About dust data, it divides | segments every measurement data for 10 minutes (600 pieces), and calculates | requires an average value for every area by calculation.
(9) For the dust data, a graph is drawn with the above average value as the vertical axis and time-dependent elements such as date and time as the horizontal axis.

  Incidentally, the master measurement unit (main measurement device) 2 according to the present embodiment measures temperature (air temperature), humidity, wind direction, wind speed, and the like as environmental information. For example, WBGT measured by the WBGT meter. Using (Wet Bull Globe Temperature: wet bulb black bulb temperature) or as a configuration that can obtain wet and dry bulb temperature, black bulb temperature, determine the onset level of heat stroke around the current construction site, It can also be configured to notify that effect.

  That is, for prevention of heat stroke, WBGT measured by a WBGT meter or WBGT = “0.7 × wet bulb temperature + 0.2 × black bulb temperature + 0.1 × dry bulb temperature” (in the case of outdoor with sunlight) WBGT is calculated from the calculation formula of), and it is important to manage the work contents etc. by referring to the table as shown in FIG. 13 (example of acceptable standards at work sites, Japan Society for Occupational Health, 1982). In this embodiment, such processing management is executed by the master measuring unit (main measuring device) 2 or the PC in the management office 10 to give warnings / warning warnings regarding heat stroke to workers at construction sites, heavy equipment operators, etc. This can be notified via a mobile phone, heavy equipment monitor 3A, broadcast, etc., and can contribute to prevention of heat stroke.

  The master measuring unit (main measuring device) 2 or the PC in the management office 10 displays these information on a display monitor (information monitor) 4 so that the local residents can be alerted to heat stroke, warning alerts, etc. Information can also be provided.

  By the way, even when a WBGT meter is not provided, for example, the dry bulb temperature (or wet bulb temperature or wet bulb temperature) is used by using the comparison data of WBGT and dry bulb temperature (or wet bulb temperature) as shown in FIG. It is also possible to predict a heat stroke attention level based on the bulb temperature) and to issue a warning / warning warning for the heat stroke.

  In this embodiment, the wind direction and wind speed are acquired, and this information is used by managers and workers (including heavy machinery operators) for construction conditions of concrete placement work and crane lifting work at the construction site. Can be used for confirmation and management.

Further, in the present embodiment, wind direction / wind speed information can be used as follows.
That is, the dust measurement data can be determined in association with the wind direction wind speed measurement data.

(1) The wind direction in the site can be seen with the anemometer. This can be used to determine the accuracy of dust data.
a) In the case of “windward dust data”> “leeward dust data” Dust is not generated at the construction site.
b) In the case of “windward dust data” <“windward dust data” It can be determined that there is a high possibility that the difference between leeward and windward is dust generated in the construction site.

(2) When there is almost no wind speed (less than 0.2m / s) a) When the dust value of the whole construction site (multiple measurement points) is high, the measured dust data is not reliable (external It can be judged that there is an environmental impact.
b) When the dust value at a specific measurement point is high, it can be determined that there may be a disturbance or the like that affects the dust data near the measurement point.

(3) When the humidity is high and the overall dust value is high, water droplets such as mist may be affected, so that it can be determined that the measurement data of the dust lacks reliability.
However, an adverse effect on humidity can be avoided by using an SPM (floating particulate matter) meter as the dust meter.

Regarding the vibration, the operation status of the heavy machinery 3, that is, the relationship with the lever operation can be considered.
In particular, the occurrence of vibration occurs when the heavy machinery 3 travels, when performing an operation of stretching with the attachment 3C, when performing an operation of pushing away an object with the attachment 3C or the arm 3B while turning with a revolving structure, etc. When the work is performed with a mixture of heavy machines 3, the lever operation signal of each heavy machine 3 is sent to the master measurement unit 2, a PC in the management office 10, etc., and the master measurement unit 2 or the management office 10. In the PC, etc., the vibration measurement data and the lever operation signal are associated with each other, a heavy machine that is likely to generate vibration is identified, and a caution or warning alarm is notified. Is also possible.

  As described above, the environmental information monitoring and management system according to the present embodiment transmits environmental information (noise, vibration, dust, wind direction, wind speed, temperature, humidity, etc.) in a monitoring target area such as a construction site at predetermined time intervals ( For example, the master measurement unit 2 automatically acquires the acquired environment information at intervals of 1 second, and the master measurement unit 2 has a high degree of request for real-time information provision (for example, a heavy equipment operator, a monitor for neighboring residents, and further management) PCs in the office 10 can also be included upon request), while direct transmission via wireless etc., various processing operations are performed relatively slowly on the transmitted environmental information It is configured so that it can be used via the Internet for objects that require a high degree of demand (for example, management offices, head office departments, design offices, neighboring houses, etc.) In, it is possible to achieve provision of information according to user's demand of environmental information, it is possible to provide a more user friendly environment information monitoring management system as compared with the conventional I following.

  In addition, for example, for the display of measurement data such as the heavy equipment monitor 3A, the display monitor 4 for residents in the vicinity, and the PC in the management office 10, the display form can be changed as appropriate according to the purpose. A user-friendly environment information monitoring and management system can be provided, which can easily and quickly respond to various requests of users.

  Furthermore, in this embodiment, since it is configured to measure and monitor environmental data with a high degree of demand at civil engineering construction sites, building construction sites, etc., it is possible to reduce costs while maintaining a predetermined degree of installation flexibility such as installation space. You can also plan.

By the way, the environmental information according to the present embodiment can include video data, audio data, and the like, and can be used for verifying the work, operation, event, etc. that cause noise, vibration, and dust. You can also.
In addition, for example, based on the measurement data of the noise and vibration level at each measurement point, the power level of the noise source and vibration source is predicted, and the noise level and vibration level in an arbitrary place within the monitoring target area are predicted. Is also possible.
The environmental information monitoring and management system according to the present embodiment is not limited to the case where it is used at a construction site or the like. In addition to public facilities such as schools and parks, It can also be used for crime prevention purposes.
In the present embodiment, the heavy machinery is used as the work machine. However, the present invention is not limited to this, and the present invention is not limited to this. Applicable to all work machines regardless of the formula.

  The embodiment according to the present invention described above is merely an example for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
