  According to the environmental impact monitoring system of the present invention, a base station capable of wirelessly communicating information between an information collection unit mounted on construction equipment located in or near the construction area and the information collection unit Including a unit and a base system connected to the base station unit via a communication line, the information collecting unit identifies the current position by the position identifying means, and the measurement means measures the environmental impact, and the position identifying means The wireless communication means wirelessly transmits the position information indicating the position specified by the measurement means and the measurement result to the base station unit, and the base station unit receives the position information and the measurement result wirelessly transmitted from the information collection unit. And the received location information and measurement results are transmitted to the base system by a transmission means. The position information and measurement results transmitted from the base station unit are received by the base receiving means, and the calculation means performs calculation processing for predicting environmental influence based on the received position information and measurement results, Since the result is output by the output means, by measuring the environmental impact at the source and identifying the location of the source by the information collection unit mounted on the construction equipment that is the source of the environmental impact such as noise and vibration, The environmental impact can be predicted based on the measurement result and the position of the source, and the environmental impact can be predicted with extremely high accuracy. In addition, since the information collection unit and the base station unit are capable of wireless communication, and the base station unit and the base system are connected via a communication line, in the base system, position information and measurement results in the information collection unit It is possible to get quickly. Therefore, it is possible to perform prediction in almost real time based on the measurement result in the information collection unit. Furthermore, it is sufficient for the information collecting unit to prepare, for example, the number of construction equipment, and it is not necessary to use the number corresponding to the area of the construction area. For this reason, even if the construction area has a vast area, it can be realized at low cost.

Therefore, even if the information collection unit is installed, the mobility of the construction equipment is high. It will not be damaged and will not hinder the progress of construction.
Further, since the base station unit and the base system need only be connected via a communication line, the base system can be installed at a location separated from the construction area. For this reason, the environmental influence by the construction in the construction area can be monitored at a position away from the construction area.

  In addition, the measurement means of the information collection unit includes either or both of noise measurement means for measuring noise and vibration measurement means for measuring vibration, and measures either or both of noise measurement values and vibration measurement values.

The fixed point observation unit measures the environmental impact, transmits the measurement result to the base station unit, and the base station unit transmits the fixed point observation unit. When the measurement result transmitted from the is received and transmitted to the base system, and the base system corrects the result of the calculation processing by the calculation means based on the measurement result from the fixed point observation unit, the calculation is output. It is possible to perform prediction with higher accuracy by correcting the prediction result of the environmental influence obtained by the means based on the actual measurement value in another place.

  Further, if the base system is configured to perform warning notification by the notification means when the result of the calculation processing by the calculation means indicates a predicted value of the environmental influence exceeding a predetermined level, the level at which the environmental influence is allowed is set. When it exceeds, it can respond quickly and can monitor construction efficiently and accurately.

  In addition, when the photographing means is used to photograph the inside or the vicinity of the construction area and output a photographed image, and the base system includes an object moving at a speed exceeding a predetermined speed in the photographed image output from the photographing means. If it is configured to provide warning notification by means of notification, for example, environmental impacts caused by construction equipment that does not have an information collection unit, such as environmental impacts caused by construction vehicles traveling beyond the speed limit, can be accurately monitored. It becomes possible to do.

In particular, the vibration measuring device 113 in the information collecting unit 11 is mounted on a construction machine such as a moving construction machine (not shown). It is preferable to attach it at an optimal place for measuring

Here, a specific configuration of the vibration measuring apparatus 113 will be described with reference to FIG.
FIG. 5 is a cross-sectional view showing the configuration and operation of the housed vibration measurement device 3 as an example of the vibration measurement device 113. FIG. 5 (a) shows an initial state, and FIG. The state (c) of FIG. 4 shows the state at the time of vibration measurement. Moreover, the code | symbol 1b in a figure shows the ground surface.
As shown in FIG. 5A, the housed vibration measurement device 3 houses the vibration meter 32, the battery 33, the telescopic operation unit 34, the box 35, and the pickup 36 in a box-shaped housing 31.

  Among these, the vibrometer 32 operates by receiving power from the battery 33 and measures vibration based on a signal input from the pickup 36. Each time the pickup 36 detects vibration, the pickup 36 outputs a signal indicating the magnitude of the detected vibration to the vibrometer 32 via the signal cable 361. The expansion / contraction operation unit 34 expands and contracts by power such as air pressure or hydraulic pressure.

  The casing 31 is fixed, for example, such that the upper end is in contact with the bottom of the chassis of the construction equipment (not shown) and the lower surface faces the ground surface 1b. The lower surface of the housing 31 is open, and the box 35 is accommodated in the opening. The box 35 is fixed to the housing 31 via the expansion / contraction operation unit 34 and moves up and down by the expansion / contraction operation of the expansion / contraction operation unit 34.

As a result, as shown in FIG. 5C, only the box upper part 351 is pulled upward, and the box lower part 352 is placed on the ground surface 1b.

The box upper part 351 and the box lower part 352 are connected by a wire 353. In the state shown in FIG. 5C, the wire 353 is in a state where no tension is generated, that is, in a slack state, and the box lower part 352 is supported only by the ground surface 1b.

By winding up the wire 353, the box lower part 352 and the box upper part 351 can be coupled again and the box lower part 352 can be pulled up. Further, the box upper part 351 is lowered with respect to the box lower part 352 of the ground surface 1b, and the box upper part 351 and the box lower part 352 are fitted again, whereby the box lower part 352 is pulled up to the housing 31. It is good also as a structure to accommodate.
Moreover, the shape of the housing | casing 31 is not limited to a box shape, It can be set as the shape suitable for attachment to a construction machine etc., The shape of the box 35, etc. are also arbitrary. The vibrometer 32 is supplied with power from the battery 33, and is powered by a cigarette lighter socket of a construction machine or the like to which the housed vibration measuring device 3 is attached, or another power source such as a fuel cell (not shown). You may make it receive supply.

  In the state shown in FIG. 5C, since the box lower part 352 is supported only by the ground surface 1b, vibration on the ground surface 1b can be accurately detected by the pickup 36. In addition, after the measurement of vibration is completed, if the box lower part 352 is raised and accommodated in the housing 31, the construction equipment (not shown) can be moved.

  In this way, by using the housed vibration measurement device 3 that grounds the pickup 36 only during vibration measurement, the work equipment (not shown) is directly under or near the work equipment (not shown) without impairing the mobility of the work equipment (not shown). The vibration at can be measured. In addition, since the rolling is performed by the pressing force by the expansion / contraction operation unit 34 before the vibration measurement, the vibration can be measured with high accuracy by leveling the surface on which the pickup 36 is placed.

It outputs to the control part 141 and the output part 145. In addition, the calculation unit 144 executes calculation processing for obtaining predicted values of noise and vibration at a plurality of prediction points based on the information acquired by the information acquisition unit 143 according to control by the control unit 141, and the obtained prediction The values are combined to create a contour diagram and output to the control unit 141 and the output unit 145.

  Here, as an example of the calculation process by the calculation unit 144, a process for obtaining a noise prediction value at a specific prediction point using a prediction formula based on a sound propagation theory, and a combination of noise prediction values at a plurality of prediction points Processing to be performed will be described.

The following expression (1) is an arithmetic expression for synthesizing prediction values at a plurality of prediction points. The following equation (2) is an arithmetic expression for predicting noise at a specific prediction point based on the measured noise level and the position information of the measurement point.
The measured noise level is set as the parameter “L _Awi ”, the distance from the measurement point to the predicted point is obtained based on the position information of the measurement point, and this distance is set as the parameter “r _i ” and assigned to the following equation (2). By doing so, the noise level at the predicted point can be obtained.
A plurality of noise levels obtained by the following equation (1) can be synthesized by the following equation (2). The synthesis by the following formula (2) is to synthesize the influence of noise sources such as a plurality of construction machines with respect to one predicted point. As a result, it is possible to predict a noise level reflecting the influence of a plurality of noise sources.
Furthermore, when creating a contour map in a predetermined range, the predetermined range is divided into meshes, and a process for obtaining a noise level in each mesh by calculation based on the following equations (1) and (2) is performed.

  Note that the method of predicting noise by the calculation unit 144 is not limited to the method using the above-described prediction formula based on the sound propagation theory, and other methods can be used. The same applies to the method of predicting vibration by the calculation unit 144.

  Furthermore, the calculation unit 144 not only performs calculation based on the above-described prediction formula, but also, for example, the predicted value obtained from the noise level, vibration level, and position information transmitted from the information collection unit 11 is fixed-point observation. It is possible to perform a correction process based on the noise level and the vibration level transmitted from the unit 12. In this case, noise and vibration can be predicted with higher accuracy.

  In addition, the calculation unit 144 can output the information acquired by the information acquisition unit 143 to the control unit 141 as it is. For example, the noise level, vibration level, and information for identifying the fixed point observation unit 12 acquired by the information acquisition unit 143 can be associated with each other and output to the control unit 141. .

  The output unit 145 generates data for displaying the calculation result obtained by the calculation by the calculation unit 144 and outputs the data to the display unit 146.

  The display unit 146 includes a display screen (not shown) such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display). Based on data input from the output unit 145, the display unit 146 displays calculation results and the like on the display screen. indicate.

  The alarm output unit 147 outputs an alarm according to the control of the control unit 141. Here, examples of a method for outputting an alarm include warning display on a display screen (not shown), output of an alarm sound, output of a warning message, lighting of a warning lamp (not shown), and the like. Furthermore, as a configuration in which a communication function is implemented in the alarm output unit 147, an e-mail based on a predetermined fixed sentence may be created and transmitted to a pre-specified e-mail address.

  The input unit 148 is an input device for inputting instructions to the control unit 141, and may include a keyboard (not shown), a mouse (not shown), or a communication line (not shown). It may be a remote device connected via the network.

By configuring the information collection unit 11, the fixed point observation unit 12, the on-site base station 13 and the base system 14 as described above, the base system 14 grounded at a point separated from the construction area 1a has the inside of the construction area 1a and its Based on the measurement results of noise and vibration in the vicinity, it is possible to predict and calculate noise and vibration at a predetermined predicted point or range.
This calculation result is based on the measurement result by the information collection unit 11 attached to the construction equipment (not shown) as the noise source and the vibration source. Specifically, the level of noise measured in the information collection unit 11 and It is obtained by calculation based on the vibration level and the position information of the information collection unit 11, and it can be naturally expected that the accuracy will be very high. Moreover, if the information collection unit 11 is the same number as the construction equipment (not shown) in the construction area 1a, for example, the object can be sufficiently achieved. For this reason, even if the construction area 1a has a vast area, the number of the information collection units 11 is relatively small, and the cost for installing the information collection unit 11 can be suppressed to a low price. Furthermore, since the information collection unit 11 performs wireless communication with the on-site base station 13 installed in the construction area 1a, it is not necessary to connect a wired cable to the information collection unit 11. For this reason, the information collection unit 11 can be attached without impairing the mobility of construction equipment (not shown).

  Further, the base system 14 corrects the predicted values of noise and vibration based on the measurement results in one or a plurality of fixed point observation units 12 installed in or near the construction area 1a. Predictable. In particular, the fixed point observation unit 12 is located at a location different from the construction equipment on which the information collection unit 11 is mounted, and can be installed at a location far away. Therefore, the accuracy of the prediction result can be remarkably improved by correcting the prediction result based on the actually measured values at the distant positions.

  Furthermore, the information collection unit 11 and the fixed point observation unit 12 installed in the construction area 1a or in the vicinity thereof both transmit information such as measurement results to the site base station 13, and these information are stored in the site base station 13. To the base system 14 via the communication network 20. Accordingly, it is sufficient that only the on-site base station 13 is connected to the communication line network 20, and there is no need to directly transmit information from each information collection unit 11 and each fixed point observation unit 12 to the base system 14. For this reason, it becomes possible to keep the communication cost by installing the information collection unit 11 and the fixed point observation unit 12 extremely low.

  Moreover, the information collection unit 11 and the fixed point observation unit 12 can measure noise and vibration as needed, and can wirelessly transmit information including the measurement result to the site base station 13. Further, since the site base station 13 and the base system 14 are connected via the communication network 20, the base system 14 can acquire measurement results in almost real time and perform prediction based on the measurement results. It is. As a result, real-time noise and vibration prediction, which has been extremely difficult in the past, can be realized.

  In the base system 14, a warning is output by the warning output unit 147 when the calculation result by the calculation unit 144, that is, the prediction result exceeds a preset warning level. It becomes possible to respond quickly when the level exceeds the allowable level.

  Further, the base system 14 can generate and output data for displaying a contour diagram based on the predicted value of noise or vibration in a predetermined range (region) based on the calculation result by the calculation unit 144. Therefore, noise or vibration in a predetermined range can be visualized and the influence on the surrounding environment can be grasped in a plane.
