Description

Nuisance measurement device.

The present invention relates to the field of devices for measuring nuisances, such as a noise level in a given place.

BACKGROUND OF THE INVENTION

It is known to measure nuisances, such as noise pollution using specialized measuring devices.

Each nuisance is characterized using a device specifically adapted to the type of nuisance to be measured.

Generally, the measurement of a given nuisance involves the intervention of a specialist in this nuisance and the use of specialized measuring equipment.

These interventions are expensive and make it possible to obtain measurement results that are more or less reliable and difficult to compare with each other due to the variability of the measurement protocols and the variety of equipment used for the measurements.

It would be useful to simplify the measurement of nuisances of various kinds.

OBJECT OF THE INVENTION

An object of the present invention is to provide a device for measuring nuisances making it possible to resolve at least some of the defects of the aforementioned prior art.

To this end, the invention relates to a nuisance measurement device comprising:

- a box ;

- A data centralization unit arranged in the cabinet.

This nuisance measuring device according to the invention is essentially characterized in that it comprises:

- at least one noise detector adapted to generate a first signal representative of ambient noise;

- at least one dust detector adapted to generate a second signal representative of a quantity of dust in the environment of the dust detector;

- at least one vibration detector adapted to generate a third signal representative of vibrations in the environment of this at least one vibration detector;

- said data centralization unit being functionally connected to each of said noise, dust and vibration detectors to receive each of said first, second and third signals;

- at least one data recording medium communicating with said data centralization unit to store data representative of the first, second and third signals received by the data centralization unit.

Thanks to the invention, a single device makes it possible to collect signals originating from different types of detectors, each type of detector being specialized in the measurement of a given type of nuisance among noise, dust in the ambient air where find the device and vibration.

As these nuisances are detected at the same time by the same device, they can be recorded on the same data recording medium communicating with the data centralization unit which collects the signals generated by the detectors. This facilitates the establishment of correlation links between these nuisances as well as the analysis of these nuisances.

The device according to the invention is an easy-to-use tool.

The operator of the device according to the invention is not necessarily a specialist in each of the nuisances measured/studied.

The recording of data representative of the various nuisances is carried out automatically, even in the absence of an operator.

Preferably, the data representative of the first, second and third signals are combined in the same file arranged to show the evolution of each of the nuisances detected on a common time base.

The recorded data can be studied a posteriori by specialists in each of these nuisances and these data can be correlated with each other because they are obtained by the same device installed in a given place.

Another advantage of the device according to the invention is that it is easy to transport and not very fragile (the data centralization unit and sensitive detection elements are advantageously integrated into the cabinet).

The detectors of the different types of nuisances belong to the same mobile device, which facilitates the measurement of these nuisances.

The device box is preferentially dustproof and preferentially resistant to water splashes, preferentially IP64, which allows it to be used on a construction / demolition site.

The constituent material of the cabinet is for example a polymer material having an impact resistance of at least 6 joules.

Thus, the device according to the invention is particularly suitable for being installed on a building or public works construction or demolition site.

The device according to the invention is particularly useful for monitoring site nuisances by an engineering office or a project management office.

As the data centralization unit is placed in the box, it is protected against the risk of damage and can remain on site for the duration of the work.

We can thus characterize in real time the nuisances generated by the construction site and keep a recorded trace.

It sometimes happens that some local residents/customers complain of nuisance related to noise, vibrations or even dust from the crushing of concrete, in particular.

The measurement of the nuisances by the device according to the invention makes it possible to anticipate and control the inconvenience caused during the work.

Thus, in a particular embodiment, the device according to the invention may comprise alert equipment arranged to, as a function of the first, second and third signals, detect the reaching of a predetermined nuisance threshold, this equipment the alert also being arranged to generate an alert signal in the event of reaching said predetermined nuisance threshold.

This warning signal can be:

- an electronic signal transmitted by a network card belonging to the device according to the invention to a telecommunications network; and or

- a sound signal generated by a loudspeaker belonging to the device according to the invention; and or

- a visual alert generated by a light source belonging to the device according to the invention.

The device according to the invention can be used to act preventively and in real time in order to minimize the nuisance caused by the construction site and thus remain below a maximum tolerated/authorized nuisance threshold.

Site activities likely to cause nuisance can be adapted in real time based on the nuisance detected to minimize the level of nuisance detected.

According to another aspect, the invention relates to a method for monitoring nuisances on a demolition (or possibly construction) site, this method comprising:

- the installation on the construction site of a device according to any one of the embodiments of the device according to the invention;

- the detection of nuisances using said detectors;

- the generation and recording of a time-stamped computer file containing said data representative of the first, second and third signals received by the data centralization unit.

This time-stamped file which is recorded on said recording medium of the device forms a summary of the nuisances measured over a given period of time.

The timestamping of the file can be carried out using time information delivered by a clock belonging to the device according to the invention.

Preferably, this file also includes geolocation information representative at least of the geolocated position of the box during a nuisance detection range by the detectors.

Preferably, the geolocation information comprises firstly geolocation data assigned to the box and geolocation data assigned to at least one of the detectors, these geolocation data being different from each other.

Thus, the device according to the invention can carry out measurements with detectors implanted in different geolocated locations around the cabinet.

Preferably, the geolocated position of the cabinet is given by said device for geolocating the device which is preferentially attached to the cabinet.

Other characteristics and advantages of the invention will emerge clearly from the description given of it below, by way of indication and in no way limiting, with reference to the appended drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION

Different embodiments of the nuisance measuring device 1 are presented in FIGS. 1a to 3, this device is particularly suitable for measuring nuisances on a demolition or construction site.

This device 1 comprises:

- a box 2;

- A data centralization unit 3 arranged in the cabinet 2;

- at least one noise detector Db1 adapted to generate a first signal representative of ambient noises measured around said at least one noise detector;

- at least one dust detector Dp1 adapted to generate a second signal representative of a quantity of dust in the environment of the dust detector, outside the box 2;

- at least one vibration detector Dv1, Dv2, Dvn adapted to generate a third signal representative of vibrations in the environment of this at least one vibration detector Dv1, Dv2, Dvn;

- Said data centralization unit 3 is functionally connected to each of the noise, dust and vibration detectors Db1, Dp1, Dv1, Dv2, Dvn to receive each of said first, second and third signals; And

- at least one data recording medium 4 communicates with said data centralization unit 3 to store data representative of the first, second and third signals received by the data centralization unit 3.

The number of different detectors and the locations of the different detectors may vary depending on the nature of the nuisances to be measured.

Thus, although the device illustrated comprises only one dust detector Dp1 carried by the cabinet 2, this device 1 could also comprise other dust detectors arranged at a distance from the cabinet to measure concentrations/natures of ambient dust in different places distant from the cabinet 2.

The Dp1 dust detector may include an open duct (at the level of the Dp1x dust suction zone of the Dp1 detector) outside the box 2 to allow the surrounding air to pass through the duct.

This dust detector also includes an optical dust detection apparatus passing through this duct.

This optical detection apparatus may comprise at least one infrared light-emitting diode to generate light in the duct and at least one light sensor to receive light emitted into the duct by the light-emitting diode (this light sensor comprises for example a phototransistor).

This light sensor can be arranged to generate an optical measurement signal, said second signal being a function of this optical measurement signal.

Depending on the case, this optical measurement signal may be said second signal or the second signal may be generated as a function of this optical measurement signal by an optical measurement signal processing unit.

The light sensor is for example arranged so that the characteristics of the light received from the light-emitting diode and picked up by the light sensor vary according to the particles and/or smoke present in the duct.

The second signal generated by the dust detector may be representative of a light reflected by dust passing through the duct and/or of a light passing through this dust.

Such a detector is effective for detecting very fine particles. In addition, it can be used to distinguish smoke and dust, this information being encoded in the second signal.

Although the device 1 illustrated in FIGS. 1a to 3 comprises only one noise detector Db1 carried by the cabinet 2, this device 1 could also comprise other noise detectors arranged at a distance from the cabinet 2 so as to measure intensities and/or natures of ambient noise in different places distant from the cabinet 2.

The Db1 noise detector is also known as a sound level meter.

In the embodiment illustrated by FIGS. 1a and 1b, device 1 comprises only one vibration detector Dv1 located at a distance from box 2.

This device 1 could also include other vibration detectors which could be, depending on the number of vibration measurement points to be made and according to the arrangement of these points vis-à-vis the cabinet:

- carried by box 2, like the Dv2 detector illustrated in ;

- remote / remote from the cabinet like the plurality of Dv1 and Dvn vibration detectors illustrated on this same .

Each of these vibration detectors is preferably at least arranged to detect vibrational frequencies and vibration intensities at each of these frequencies.

Whatever the number and the nature of the detectors, these generate signals which are transmitted to the centralization unit 3 which centralizes the data of these signals (in the cabinet 2, away from the nuisance) and manages the storage of these data by a data recording medium 4 which belongs to the device.

Preferably, said at least one vibration detector Dv1, Dv2 comprises fixing elements for fixing it to the ground.

For example, a Dvx fastener may include at least one screw anchor and/or glue.

Preferably, this fixing element is in mechanical engagement with a housing of the vibration detector Dv1, Dv2 which it fixes to the ground.

Preferably, this Dvx fixing element forms a breakable seal in the event of displacement of the vibration detector relative to the ground against which this detector is fixed.

Fixing the vibration detector to the ground improves the quality of ground vibration measurement and avoids untimely movement of this detector, which would falsify the relevance of the measurements.

Here each detector Dv1, Dp1, Db1 communicates with the data centralization unit 3 via a wired link.

To this end, several communication cables Cb allow the transmission/communication of signals generated by the detectors Dv1, Dp1, Db1 to the data centralization unit 3.

However, the transmission/communication of the signals generated by at least some of the detectors could take place via wireless communication links.

A wireless communication link has the advantage of deporting the detectors vis-à-vis box 2 while avoiding the inconvenience caused by communication cables running on the site.

Data centralization unit 3 is located in the lower part of cabinet 2, under the particle detector.

The data centralization unit 3 comprises a calculation unit 31 for carrying out operations for managing the detectors and communication ports for communicating with these detectors and other components of the device as well as for managing communications with components external to the device 1 according to the invention.

The centralization unit 3 also includes memories 4 (also called data recording medium) for storing calculation operators and the results of these calculations.

The device according to the invention can also comprise an apparatus for supplying electrical energy Alim equipped with a battery Bt.

This Alim supply device is functionally connected to the data centralization unit 3 and to the detectors in order to supply them with energy.

This Alim supply device can also include:

a power cable, one end Pr of which is located outside the box 2 to be connected to a power supply network external to the device 1;

an electric transformer connected to a second end of the power supply cable and arranged to supply a power supply to the data centralization unit 3 and to the detectors Dp1, Db1, Dv1 from an electric power coming from said network of power supply external to the device; And

a charging circuit for said battery Bt, the transformer and the battery charging circuit located in box 2.

Preferably, the battery is adapted to guarantee operating autonomy of the device 1 for at least 24 hours.

The device 1 according to the invention can also include a timestamping device 5.

In this embodiment, the centralization unit 3 is arranged so that at least some of the data stored on said at least one recording medium 4 are timestamped using time data supplied by said timestamping device 5.

This time-stamping device 5 can be arranged to communicate with a clock remote from the device in order to synchronize the time-stamping device with a time reference given by the remote clock.

The device according to the invention can also comprise one or more geolocation devices 6, 61, 6n.

In this case, the centralization unit 3 is arranged so that at least some of the data stored on said at least one recording medium 4 are geolocated using geolocation data provided by said geolocation device 6, 61 , 6n.

By geolocated stored data, it is to be understood that these stored data are associated with at least one location corresponding to at least one place where an element of the device according to the invention is located, such as the place of installation of its box and/or the location of one of its detectors at the time of generation of the stored data.

For example, a geolocation device 6, 61, 6n can include a location receiver such as a GPS receiver.

The use of geolocated data improves confidence in the recorded data.

Such geolocated data can be useful for refining the study of nuisances and for developing actions aimed at minimizing these nuisances.

Indeed, by knowing precisely how to locate a nuisance, it is possible to act either on the localized source of the nuisance, or on the effects of this nuisance by setting up screens between this source of nuisance and the people / infrastructures subject to the nuisance.

Moreover, as these data are geolocated, the stored data can be used to establish a history of the nuisances measured in a given place, this history being able to serve as reliable legal proof.

Preferably, the centralization unit 3 is arranged so that at least some of the data stored on said at least one recording medium 4 are associated with geolocation data of the box 2.

This makes it possible to know the precise location of the installation of box 2 where the signals are centralized.

To this end, the centralization unit 3 can be arranged to receive geolocation information from the centralization unit, and possibly from at least some of the detectors, and to generate and record an alert signal in the event of detection of moving the centralization unit.

In particular, the centralization unit 3 can be arranged to generate this alert in the event of the box 2 moving while at least one of the first, second and third signals is being generated.

Such an alert can be recorded and/or transmitted to a data certification operator in charge of verifying the detection conditions.

The device 1 according to the invention can also comprise an apparatus 7 for transmitting data to a telecommunications network 8.

This transmission device 7 is preferably at least partially placed in the cabinet 2.

The telecommunications network 8 can be at least one of the networks chosen from a computer network, mobile telephone network/GSM network, an Internet network.

The device according to the invention may itself belong to a system S comprising a control unit UC remote from the device 1, this control unit UC being arranged to receive the data transmitted by the data centralization unit 3.

This control unit UC can be arranged to transmit instructions to the device 1 according to the invention, such as an instruction for transmitting data representative of the current state of the device.

In response to this instruction, device 1 can transmit a status signal of the various detectors and of the current position of the box and possibly of the current position of the various detectors.

It should be noted that the current position of a given detector of the device can be identical to that of box 2 (for example because this given detector is carried by the box, as is the case of the dust detector Dp1) or can be indicated by an electronic location card specific to the given detector which is integrated into this given detector (as is the case for the remote vibration detectors Dv1, Dvn).

The data transmission apparatus 7 is here functionally connected to the data centralization unit 3 to transmit, via a telecommunications network 8 (which is external to the device of the invention), at least some of the data representative of the first , second and third signals received by the data centralization unit 3.

As can be understood from the observation of FIGS. 1a, 2a, 2b and 3, the device is arranged to selectively adopt one configuration from among a transport configuration and a detection configuration.

In the transport configuration, each of said detectors Db1, Dp1, Dv1, Dv2, Dvn is placed inside said box 2 and in the detection configuration at least some of the detectors Db1, Dp1, Dv1, Dv2, Dvn are placed outside outside of said box 2 to carry out measurements in spaces external to box 2.

Thus, as illustrated in Figures 2a, 2b and 3, said at least one dust detector Dp1 can be connected to said box 2 via a guide mechanism 20 to move it between:

- a position of use in which at least one dust suction zone Dp1x of the dust detector Dp1 is located outside the box 2 to collect dust therefrom; And

- A storage position in which said at least one Dp1x suction zone is inside the box 2 to be preserved there.

The dust detector is placed in its position of use when the device is in its transport configuration, which protects the detector during transport.

The Dp1x suction zone is preferably one end of a dust suction cannula.

Preferably, the sensitive zone of the dust detector generating the second signal is arranged to be in the cabinet 2, including when said at least one dust detector Dp1 is in its use or storage positions.

The illustrated guide mechanism 20 comprises at least one guide rail 20a, 20b on which the dust detector Dp1 is slidably mounted between its use position and its storage position.

This guide mechanism 20 is preferably equipped with a 20X lock located in said cabinet 2 to selectively lock said dust detector Dp1 when it is in at least one of its use and storage positions.

The cabinet 2 comprises a cover 22 movable between a closed position of the cabinet (to prevent access to the interior of this cabinet) and an open position to allow manual access to the interior of the cabinet.

Access to the box is useful for storing the various detectors or for extracting them in order to carry out measurements.

Access is also useful for carrying out manual parameterization of the device according to the invention.

A closing device 21 of the cabinet 2 is arranged to hold the cover 22 of the cabinet 2 in its position for closing the cabinet.

This closing device 21 of the box 2 is for example selected from the group of closing means comprising a lock, a padlock, a breakable seal in the event of opening of the box or a combination of these means.

Preferably, the box 2 is equipped with wheels 9 to support the box and move it by rolling on the ground.

When placed in its transport configuration, the device 1 has dimensions in length, width and thickness of less than 1 m and a weight of less than 50 kg.

Thus, the device according to the invention can be moved by an operator to install it on the site of interest.

To facilitate its movement, said box 2 is preferably equipped with a manual transport handle 10.

This manual transport handle 10 is preferably telescopic and movable between a storage position against the cabinet and a transport position away from the cabinet to which it is mechanically fixed via telescopic arms.

In the embodiment illustrated in Figures 1a, 1b, the handle is equipped with an attachment zone to support the noise detector Db1.

This makes it possible to position this detector Db1 at a predetermined fixed height relative to the ground on which the box 2 is located.

The noise measurement conditions are thus reproduced by limiting the disturbances caused by the box 2 which is under the noise detector.

In a particular embodiment, the box 2 may comprise fixing equipment arranged to fix this box to the ground (for example by screwing or sealing).

This fixing equipment may have a mobile actuation zone between a configuration for fixing the box with respect to the ground and a configuration for releasing the box with respect to the ground.

This actuation zone is preferably provided to be exclusively accessible from inside the box 2 when the latter is open.

In this particular embodiment, it is possible to decide to install the device 1 in a specific place, via the actuation of the equipment for fixing the box to the ground.

Once this fixing has been made, simply close and lock the box (using the lock 21) to prevent access to the activation zone of the fixing equipment and thus guarantee that the box cannot be moved.

The integrity of the conditions of the nuisance measurement can thus be preserved.

As the data recording medium 4 is preferably placed inside the box 2, this medium is preserved in the box and its access is reserved for the sole operator having the means to actuate the box closing device.

It should be noted that a second data recording medium can be placed outside the box 2 and at a distance from the latter to store therein at least some of the data generated from the signals of the detectors. The doubling of recordings in separate locations promotes data security.

The data centralization unit 3 is preferably positioned in a box 3a arranged inside the box 2.

This box 3a is closed using a device 3a1 for closing this box.

Preferably, this device 3a1 for closing the case 3a is selected from the group of means comprising a lock, a padlock, a breakable seal in the event of the case being opened, or a combination of these means.

Finally, it is also possible for the system S according to the invention to comprise a third-party data recording server 40, this server 40 being remote from the device 1 according to the invention.

According to a particular embodiment, this third-party server 40 can be secured to be exclusively controlled by a trusted third party (for example a bailiff).

In this embodiment, the system S according to the invention may comprise a secure communication channel between the device 1 and the third-party registration server 40 to transmit to this third-party server, at least some of the data representative of the first, second and third signals generated by the detectors and to generate, at the level of the third-party server 40, a time-stamped file containing this data.

This timestamped file is thus saved at the level of this third-party server 40.

This timestamped file is thus placed under the control of the trusted third party.

This file can also be signed by the third-party server 40 and in this case, it can be used as proof of a level of nuisance actually measured by the device according to the invention and observed by the trusted third party.

Preferably, the third-party server 40 is arranged to automatically transmit a copy of the time-stamped file to a client of the third-party server 40, this copy serving as certified proof of the nuisances measured.
