FIG. 1 shows an application example of a first embodiment of an environment monitoring system 1 to which the present invention is applied. The environment monitoring system 1 includes a vehicle transmitting / receiving device 11 and a monitoring device 12. The vehicle transmission / reception device 11 is a small device attached to a target vehicle.
Truck A, which is a diesel car as the target vehicle,
The vehicle transmitting / receiving device 11 is mounted on a DPF filter B near the muffler C (the mounting position of the vehicle transmitting / receiving device 11 will be described later in detail). The monitoring device 12 is installed on a predetermined road in an area where exhaust gas of a diesel vehicle is desired to be measured.

The vehicle transmission / reception device 11 transmits information (hereinafter referred to as a traffic condition) relating to a target vehicle (for example, truck A) to which it is attached and a harmful substance removal filter (for example, DPF filter B of truck A). Information)
I remember.

As shown in FIG. 2, the vehicle transmitting / receiving device 11 receives a signal from the monitoring device 12 (antenna 21) and transmits the stored traffic condition information to the monitoring device 12 as shown in FIG.
(Antenna 21).

In the case of this example, the monitoring device 12 (the antenna 2
From 1), as shown in FIG.
Then, control data (for example, a command for requesting provision of traffic condition information (hereinafter, referred to as a traffic condition information request command)) and a signal wave of an unmodulated frequency f are transmitted. Therefore, the vehicle transmitting / receiving device 1
When the traffic condition information request command is transmitted, 1 changes the impedance of its own antenna unit 31 (FIG. 4) based on the stored traffic condition information,
As shown in FIG. 3B, the received signal wave of frequency f is reflected or absorbed. As a result, a signal corresponding to the traffic condition information (hereinafter, referred to as a traffic condition information signal) is output from the vehicle transmitting / receiving device 11 (antenna unit 31).

When the monitoring device 12 (antenna 21) is located behind, the vehicle transmitting / receiving device 11 transmits / receives signals to / from the monitoring device 12 (antenna 21). For example, in the case of a truck A that is not obstructed, as shown in FIGS. 1 and 2, an upper surface portion of the DPF filter B installed behind the vehicle body protruding from the vehicle body (the upper part thereof is not blocked by the vehicle body). Surface part).

Note that some vehicles exhaust exhaust gas from the side of the vehicle body depending on the type of the vehicle. In this case, since the DPF filter B is mounted on the side surface of the vehicle body, the vehicle transmitting / receiving device 11 is mounted on a portion of the DPF filter B that is exposed to the outside.

The vehicle transmitting / receiving device 11 and the monitoring device 1
The transmission and reception of signals in 2 are performed, for example, in a 5.8 GHz radio frequency band used in an automatic toll collection system for toll roads.

Returning to FIG. 1, the monitoring device 12 includes a plurality of antennas provided above each of a plurality of lanes (in this example, three lanes capable of traveling from left to right in FIG. 1). (In the case of this example, three antennas 21-1 to 21-3 (hereinafter, simply referred to as antenna 21 when there is no need to individually distinguish them. The same applies to other cases), a plurality of video cameras ( In the case of this example, the three video cameras 22-1 to 22-3) and the processing unit 23
It is composed of

The antenna 21 outputs control data frequency-modulated at a predetermined frequency f supplied from the processing unit 23 and a signal wave of the subsequent frequency f (FIG. 3 (A)) (in FIG. 2, an oblique direction is shown). Output downward).

The frequency f of this signal wave is determined for each antenna 21 (for each lane where the antenna 21 is installed) in order to correspond to a plurality of channels. The frequencies f corresponding to the antenna 21-3 are the frequencies f1, f2, and f3, respectively.

The antenna 21 also transmits a signal (for example, a traffic condition information signal) transmitted from a vehicle traveling in the lane where the antenna 21 is installed (more precisely, from the vehicle transmitting / receiving device 11 attached thereto) ( 3 (B) is received and supplied to the processing unit 23. In the example of FIG.
1-2 receives the traffic condition information signal transmitted from the vehicle transmitting / receiving device 11 of the truck A and supplies the signal to the processing unit 23.

The shape of the antenna 21 is a flat shape, so that the antenna 21 can be made small and thin.

The video camera 22 captures an image of, for example, the front of a vehicle running in the lane where the video camera 22 is installed, and supplies the image data obtained as a result to the processing unit 23. In the example of FIG. 1, the video camera 22-2 captures an image of the front part of the track A, and processes the obtained image data into the processing unit 2.
Supply 3 In addition, in FIG. 1, although the track A is shown on the right side of the video camera 22-2, that is, a state after passing the position where the video camera 22-2 is installed is shown, When the video camera 22-2 captures an image of the track A (the front portion thereof), when the track A is located on the left side of the same in FIG.
That is, an image is taken before passing. Thereby, the front surface of the track A is imaged.

The processing section 23 supplies the antenna 21 with control data modulated at the corresponding frequency f and a signal wave at the frequency f. That is, the control data modulated at the frequency f1 and the subsequent frequency f1
The control data modulated at the frequency f2 and the subsequent signal wave at the frequency f2 are transmitted to the antenna 21-2.
The control data modulated at the frequency f3 and the subsequent signal wave at the frequency f3 are supplied to the antenna 21-3.

The processing unit 23 also demodulates the traffic condition information signal supplied from the antenna 21 and transmitted from the vehicle transmitting / receiving device 11 and reads the content of the traffic condition information, so that the traveling vehicle satisfies the traffic condition. Is determined, and processing is performed based on the determination result.

The processing section 23 further performs predetermined image processing on the image data supplied from the video camera 22, and determines whether or not the captured traveling vehicle is the target vehicle. In this case, the target vehicle (for example, truck A) is larger than the non-target vehicle (for example, gasoline engine vehicle), so the processing unit 23 detects the imaged traveling vehicle ( Based on the size of the front of the traveling vehicle, it is determined whether or not it is the target vehicle.

Instead of the size of the traveling vehicle, the vehicle number can be recognized from the captured image of the license plate of the vehicle, and whether or not the vehicle is the target vehicle can be determined from the recognized vehicle number.

That is, the monitoring device 12 monitors vehicles traveling within a monitoring range (in this example, a plurality of lanes) that can be transmitted and received via the antenna 21 and can be imaged by the video camera 22. Is a target vehicle or not, and if it is a target vehicle, it is determined whether or not a traffic condition is satisfied (whether or not a harmful substance removal filter is appropriately attached), and based on these determination results, Execute a predetermined process.

FIG. 4 shows an example of the configuration of the transmitting / receiving device 11 for a vehicle. The transmitting / receiving device 11 for a vehicle includes the antenna unit 3
1, a transmission / reception unit 32, and a storage unit 33.

The antenna section 31 outputs a signal output from the antenna 21 of the monitoring device 12 (control data modulated at the frequency f, followed by a signal wave at the frequency f) (FIG. 3A).
Is received and supplied to the transmission / reception unit 32. Antenna unit 31
Further, the impedance is adjusted by the transmission / reception unit 32, and the signal wave of the frequency f to be received is absorbed or reflected according to the change in the impedance (FIG. 3B).

The transmission / reception unit 32 demodulates the frequency-modulated control data supplied from the antenna unit 31 and reads the contents. If the transmission / reception unit 32 reads that the control data is a traffic condition information request command, the transmission / reception unit 32 reads the traffic condition information stored therein from the storage unit 33, and changes the impedance of the antenna unit 31 accordingly.

FIG. 5 shows an example of the configuration of the transmission / reception section 32.

The detector 41 receives frequency-modulated control data received by the antenna unit 31 and demodulates the control data. The signal demodulated by the detector 41 is supplied to an amplifier 42 and a band-pass filter (BP).
F) At 43, and at the amplifier 44, it is amplified, filtered, and further amplified so that the binarization unit 45 can process it.

The binarization unit 45 performs a binarization process on the signal supplied from the amplifier 44 and supplies data consisting of, for example, “0” or “1” to the control unit 46.

The control unit 46 reads the contents of the data (control data) supplied from the binarization unit 45, and if it reads that it is a traffic condition information request command, it stores it in the storage unit 33 and stores it there. The traffic condition information is read, and the reflecting unit 47 is controlled to change the impedance of the antenna unit 31 accordingly. As a result, the signal wave of the frequency f received by the antenna unit 31 is absorbed or reflected in accordance with the change in the impedance, and as a result, a traffic condition information signal is output from the antenna unit 31.

Referring back to FIG. 4, the storage unit 33 stores the traffic condition information as described above. Here, the traffic condition information is, for example, identification information of a harmful substance removal filter (for example, vehicle number, ID number, etc.), expiration date of the harmful substance removal filter (for example, expiration date of replacement of consumable parts), vehicle registration year of the target vehicle, and information indicating the toxic substance removal ability of the harmful substance removal filter. As shown in FIG. 6, it is stored in the storage unit 33 as traffic condition information.

FIG. 7 shows an example of the configuration of the processing unit 23 of the monitoring device 12.

It is determined whether the vehicle is a target vehicle.

When the image processing unit 51 determines that the captured traveling vehicle is the target vehicle, it notifies the radio signal processing unit 52 of the determination.

When the image processing unit 51 notifies the image processing unit 51 that the traveling vehicle is determined to be the target vehicle, the radio signal processing unit 52 corresponds to the antenna 21 installed in the lane in which the target vehicle travels. The traffic condition information request command is modulated at the frequency f and supplied to the antenna 21 together with the signal wave at the frequency f.

In the example of FIG. 1, the image processing section 51 performs image processing on the image data from the video camera 22-2, and based on the size of the track A detected as a result, the track A It is determined that the vehicle is a vehicle, and the wireless signal processing unit 52 is notified of the determination. Upon receiving the notification, the wireless signal processing unit 52 modulates the traffic condition information request command at the frequency f2 corresponding to the antenna 21-2 and supplies the modulated command to the antenna 21-2 together with the signal wave of the frequency f2.

Further, the radio signal processor 52 is supplied with the received signal from the vehicle transmitting / receiving device 11 from the antenna 21.

When receiving the control data (passage condition information request command) via the antenna 21 before receiving the signal from the antenna 21, the radio signal processing unit 52 An AC component having the same frequency as the frequency f obtained by modulating the transmitted control data (passage condition information request command) is extracted. Thereby, for example, corresponding to the transmitted traffic condition information request command,
A traffic condition information signal from the vehicle transmitting / receiving device 11 is extracted.

The radio signal processor 52 demodulates the extracted signal (passage condition information signal) and reads the contents. When the extracted signal is a traffic condition information signal, the wireless signal processing unit 52 determines whether the traveling vehicle (target vehicle) satisfies the traffic condition based on the read content of the traffic condition information, If it is determined that the condition is not satisfied, for example, the identification information (vehicle number etc.) included in the traffic condition information

The traffic condition information request command is modulated at a frequency f corresponding to the frequency f and supplied to the antenna 21 together with a signal wave of the frequency f.

The transmission / reception unit 61 is supplied with a signal received by the antenna 21. The transmission / reception unit 61 extracts, from the signal, an AC component having the same frequency as the frequency f obtained by modulating the previously transmitted traffic condition information request command, and demodulates the traffic condition information signal obtained as a result.
To supply.

The determination section 62 reads the content of the traffic condition information, determines whether or not the traveling vehicle as the target vehicle satisfies the traffic condition based on the content, and determines that the traffic condition is not satisfied. Then, a process of outputting the information to an external management device (not shown) in association with the identification information or the captured image of the vehicle is performed.

FIG. 9 shows a configuration example of the transmission / reception unit 61.

The control unit 71 receives a notification from the image processing unit 51. When the notification is input, the control unit 71 supplies a traffic condition information request command to the modulator 72, and 72 is controlled by a signal wave of a frequency f corresponding to the antenna 21 of the lane in which the target vehicle travels,

The traffic condition information request command frequency-modulated by the frequency f in the modulator 72 and the signal wave of the unmodulated frequency f generated by the modulator 72 are amplified by the amplifier 73.
The signal is supplied to the antenna 21.

[0102] The signal received by the antenna 21 is supplied to the frequency discriminator 74. The frequency discriminator 74 is
From these signals, an AC component having the same frequency as the frequency f obtained by modulating the traffic condition information request command is extracted,
5 That is, a traffic condition information signal corresponding to the transmitted traffic condition information request command is extracted and supplied to the detector 75. The frequency discriminator 74 is a BPF
Alternatively, a superheterodyne method or the like can be used.

The detector 75 demodulates the traffic condition information signal supplied from the frequency discriminator 74. The signal demodulated by the detector 75 is amplified, filtered, and further amplified in the amplifier 76, the BPF 77, and the amplifier 78 so that the binarization unit 79 can process the signal.

The binarizing section 79 performs a binarizing process on the signal supplied from the amplifier 78, and supplies data consisting of, for example, "0" or "1" to the control section 71.

The control unit 71 reads the contents of the traffic condition information based on the data supplied from the binarization unit 79,
The reading result is supplied to the determination unit 62.

Next, the operation of the monitoring device 12 in the first embodiment of the environment monitoring system 1 will be described with reference to the flowchart of FIG. In this case, FIG.
As an example, a case where the truck A runs in the monitoring range of the monitoring device 12 will be described.

In step S 1, the video camera 22-2 of the monitoring device 12 captures an image of the front part of the truck A running on the lane where the monitoring device 12 is installed, and sends the resulting image data to the processing unit 23. Supply.

In step S2, the image processing section 51 (FIG. 7) of the processing section 23 performs predetermined image processing on the image data supplied from the video camera 22-2, and detects the size of the track A. I do.

In step S3, the image processing unit 51 of the processing unit 23 determines whether or not the truck A is the target vehicle based on the detected size of the truck A, and determines that the truck A is the target vehicle. Is notified to the wireless signal processing unit 52, and then the process proceeds to step S4. In this example, since truck A is the target vehicle, step S
Proceed to 4.

In step S4, the radio signal processing unit 52 of the processing unit 23 modulates the traffic condition information request command at the frequency f2 corresponding to the antenna 21-2 installed on the lane on which the truck A runs, and Is supplied to the antenna 21-2 together with the signal wave. As a result, a traffic condition information request command modulated at the frequency f2 and a subsequent signal wave at the frequency f2 are output from the antenna 21-2 (FIG. 3A). Note that the process of the wireless signal processing unit 52 has already been described above with reference to FIGS. 8 and 9, and the outline thereof will be described below.

The transmitting / receiving section 61 (FIG. 8) of the radio signal processing section 52 responds to the notification from the image processing section 51 that the truck A is determined to be the target vehicle (the control section 7).
1 (FIG. 9)), the traffic condition information request command is
And a signal wave of frequency f2, unmodulated, is generated (modulator 72) and after they are amplified (amplifier 7).
3), is supplied to the antenna 21.

Next, in step S5, the processing unit 23
The wireless signal processing unit 52 (FIG. 7) determines whether or not the passage condition information signal has been received by the antenna 21-2 (the antenna 2).
From 1-2, it is determined whether or not a traffic condition information signal has been supplied within a predetermined time. If it is determined that the traffic condition information signal has been received, the process proceeds to step S6. For example, if the vehicle transmitting / receiving device 11 is not attached to the target vehicle, no traffic condition information signal is transmitted from the target vehicle.
The passage condition information signal is not received by the antenna 21, and the radio signal processing unit 52 determines that the signal is not received. Since the vehicle transmitting / receiving device 11 is attached to the truck A, the process proceeds to step S6.

In step S6, the radio signal processing unit 52 of the processing unit 23 reads the content of the traffic condition information from the traffic condition information signal of the track A supplied from the antenna 21-2. Since the processing of the wireless signal processing unit 52 has already been described above, an outline thereof will be described below.

In the transmission / reception unit 61 (FIG. 8) of the radio signal processing unit 52, the frequency f used in modulating the traffic condition information request command in step S4 is obtained from the supplied signal from the antenna 21 in step S4. The AC component of the frequency is extracted (frequency discriminator 74 (FIG. 9)). The traffic condition information signal obtained as a result is demodulated (detector 75), amplified (amplifier 76), filtered (BPF 77), and further amplified (amplifier 78), and subjected to a binarization process. (A binarization unit 79). 2
The content of the traffic condition information is read from the data generated as a result of the value processing (control section 71). The read traffic condition information is supplied to the determination unit 62.

Next, in step S7, the processing unit 23
The wireless signal processing unit 52 (determination unit 62 (FIG. 8)) attaches the harmful substance removal filter to the track A with reference to the identification information of the harmful substance removal filter in the traffic condition information read in step S6. Is determined whether or not
If it is determined that it is attached, the process proceeds to step S8.

In the case of this example, the identification information stored in the storage unit 33 of the vehicular transmission / reception device 11 includes information indicating the ID number of the harmful substance removing filter when the harmful substance removing filter is attached to the target vehicle. If the substance removal filter is not attached, information indicating that fact is included. That is, when the identification information includes information corresponding to the ID number or the like of the harmful substance removal filter, it is determined that the harmful substance removal filter is attached. Since the identification information of the traffic condition information from the track A includes information indicating the ID number of the DPF filter B, the process proceeds to step S8.

Next, in step S8, the processing unit 23
The wireless signal processing unit 52 (determination unit 62) refers to the expiration date of the read traffic condition information, determines whether the DPF filter B attached to the truck A has expired, and If it is determined that there is not, the process proceeds to step S9.

In step S9, the radio signal processing unit 52 (judgment unit 62) of the processing unit 23 determines that the harmful substance removal capability (the harmful substance removal capability of the DPF filter B) of the read traffic condition information is the current reference value. (Value relating to harmful substances contained in exhaust gas) is determined as to whether it is sufficient.

In the case of this example, it is assumed that the reference value for the harmful substances contained in the exhaust gas gradually becomes strict (every several years), and accordingly, the harmful substance removal filter has a higher value. The ability to remove harmful substances is required. That is, when the harmful substance removing filter is attached, even if its ability is sufficient, it may not be sufficient due to the update of the reference value.

When it is determined in step S7 that the harmful substance removing filter is not attached, the process proceeds to step S10.

In step S10, the vehicle registration year of the traffic condition information read in step S6 is referred to.
At this time, it is determined whether the installation of the harmful substance removal filter is required for the target vehicle.

In the case of this example, it is assumed that the performance of the diesel engine is good for a relatively newly manufactured target vehicle, and the duty of attaching a harmful substance removal filter is required for a predetermined period (for example, several years after vehicle registration). Shall be deferred. That is, a target vehicle for which the obligation to attach a harmful substance removal filter is deferred may not be properly attached with a harmful substance removal filter during that period. That is, when the obligation to attach the harmful substance removal filter is deferred and the grace period has not elapsed, it is determined in step S10 that the attachment of the harmful substance removal filter is not obligatory. on the other hand,
If the installation obligation has not been deferred or the grace period has expired, it is determined that the installation of the harmful substance removal filter is required.

In step S5, when it is determined that the traffic condition information signal has not been received (the vehicle transmitting / receiving device 11
Is not attached), if it is determined in step S8 that the expiration date of the harmful substance removal filter has expired, it is determined in step S9 that the harmful substance removal filter does not have an appropriate harmful substance removal ability. When it is determined, or when it is determined in step S10 that the installation of the harmful substance removal filter is required (when the harmful substance removal filter is not mounted in spite of the requirement), step S11 is performed. Proceed to. That is, when the passage condition is not satisfied with respect to the attachment of the harmful substance removing filter, the process proceeds to step S11.

In step S11, the radio signal processing unit 52 (judgment unit 62) of the processing unit 23 associates, for example, the detection of the vehicle that does not satisfy the traffic condition with the identification information of the traffic condition information and the captured image of the vehicle. Then, processing such as notifying an external management device is performed. Thereafter, the process ends.

On the other hand, if it is determined in step S3 that the vehicle is not a target vehicle, or if it is determined in step S9 that the harmful substance removal capability is sufficient (in step S7, a harmful substance removal filter is attached). And it is determined in step S8 that the expiration date of the harmful substance removal filter has not expired, and that it is determined in step S9 that the expiration date is sufficient), or step S10
When it is determined that the installation of the harmful substance removal filter is not obligatory, step S11 is skipped and the process ends. That is, when the traffic condition is satisfied with respect to the installation of the harmful substance removing filter, step S1 is performed.
1 is skipped and the process ends.

Next, the operation of the vehicle transmitting / receiving device 11 of the truck A in the case of this example will be described with reference to the flowchart of FIG.

In step S21, the vehicle transmitting / receiving device 11 receives the traffic condition information request command transmitted from the monitoring device 12 (antenna 21-2), and in step S22, responds to the traffic condition information request command. Then, a traffic condition information signal is transmitted. Thereafter, the process ends.

Since the processing of the vehicle transmitting / receiving device 11 in steps S21 and S22 has already been described above, an outline thereof will be described here.

The traffic condition information request command transmitted from the antenna 21 of the monitoring device 12 is received by the antenna unit 31 (FIG. 4) of the vehicle transmission / reception device 11 and supplied to the transmission / reception unit 32. After the received traffic condition information request command is demodulated in the transmitting / receiving section 32 (detector 4
1 (FIG. 5)), amplified (amplifier 42), filtered (BPF 43), and further amplified (amplifier 44) and subjected to binarization processing (binarization section 45). From the data generated as a result of the binarization processing, the control data is read as a traffic condition information request command (control unit 46).

When the control data is read as a traffic condition information request command, the storage unit 33
Then, the traffic condition information stored therein is read (control section 46), and the impedance of the antenna section 31 is changed correspondingly (reflection section 47). Thereby, the signal wave of the frequency f2 received from the antenna 21-2 of the monitoring device 12 received by the antenna unit 31 is absorbed or reflected in accordance with the change in the impedance of the antenna unit 31, and as a result, the traffic condition information The signal is output from the antenna unit 31 (FIG. 3B).

FIG. 12 shows an example of use of the environment monitoring system 1 according to the second embodiment. The monitoring device of the environmental monitoring system 1 includes an automatic vehicle identification (AVI) instead of the video camera 22 of the monitoring device 12 of FIG.
n) A camera 101 is provided, and a processing unit 102 is provided instead of the processing unit 23.

The AVI camera 101 captures an image of the license plate of the traveling vehicle, and supplies image data obtained as a result of the capture to the processing unit 102.

As shown in FIG. 13, the processing section 102 is provided with an image processing section 111 instead of the image processing section 51 of the processing section 23 in FIG. This image processing unit 111
Based on the image data supplied from the I camera 101,
The number (vehicle number) displayed on the license plate and its position are recognized, and based on the recognition result, it is determined whether or not the traveling vehicle is the target vehicle. This is notified to the wireless signal processing unit 52.

In this example, the number 4 is displayed at a predetermined position on the license plate of the target vehicle. That is, when it is recognized that the number 4 is displayed at a predetermined position on the license plate, it is determined that the vehicle is the target vehicle,
When it is recognized that the number 4 is not displayed at a predetermined position, it is determined that the vehicle is not the target vehicle.

Next, the operation of the monitoring device 12 in the second embodiment of the environment monitoring system 1 will be described with reference to the flowchart of FIG.

At step S31, the monitoring device 12
The AVI camera 101 captures an image of a license plate of a traveling vehicle traveling on the lane where the AVI camera is installed, and supplies the resulting image data to the processing unit 102.

In step S32, the image processing section 111 of the processing section 102 performs predetermined image processing on the image data supplied from the AVI camera 101, and recognizes the number displayed on the license plate and its position. .

In step S33, the image processing section 111 of the processing section 102 determines whether or not the number 4 is displayed at a predetermined position on the license plate based on the recognition result in step S32. Based on the result, it is determined whether or not the traveling vehicle is a target vehicle. When the image processing unit 111 determines that the traveling vehicle is the target vehicle, the image processing unit 111 notifies the wireless signal processing unit 52 of the determination, and then proceeds to step S34.

The processing in steps S34 to S40 is basically the same as the processing in steps S4 to S10 in FIG. 10, and a description thereof will be omitted.

In step S41, the radio signal processing section 52 of the processing section 102 performs processing such as notifying an external management device together with vehicle number information that a vehicle that does not satisfy the traffic conditions has been detected.

In this example, the vehicle transmitting / receiving device 1 is used.
The operation of 1 is the same as that described in the flowchart of FIG.

FIG. 15 shows a usage example of the third embodiment of the environment monitoring system 1. The monitoring device 12 in the environment monitoring system 1 monitors a vehicle traveling in one lane, and uses only one antenna 21-1 and one video camera 22-1. In this monitoring device, the monitoring device 12 of FIG. 1 is further provided with an exhaust gas sensor 201, and a processing unit 202 is provided instead of the processing unit 23.

The exhaust gas sensor 201 is installed on the side of the road so that the light beam output from the output section 211 is input to the input section 212 across the road, and after the traveling vehicle passes through it, The degree of light scattering (the degree of light scattering in exhaust gas) is detected, and the detection result is sent to the processing unit 202.

The sensor signal processing unit 221 is
When the notification is received from 1, the exhaust gas sensor 201 is controlled to start measuring the degree of light scattering in the exhaust gas of the traveling vehicle.

When it is determined that the traveling vehicle does not satisfy the traffic condition, the radio signal processing unit 52 notifies the sensor signal processing unit 221 of that.

Upon receiving the notification from the radio signal processing unit 52, the sensor signal processing unit 221 determines the degree of light scattering, which is started when it is determined that the traveling vehicle does not satisfy the traffic condition, based on the measurement result. It is determined whether or not the exhaust gas of the traveling vehicle contains a harmful substance exceeding a reference value, and a predetermined process is performed based on the determination result. For example, if it is determined that the vehicle contains a hazardous substance exceeding the reference value, the traveling vehicle is determined to be a vehicle that does not satisfy the traffic conditions, and the fact and the measured amount of the hazardous substance are notified to an external management device. Notified.

Next, the monitoring device 12 in the case of this example will be described.

The processing in steps S51 to S53 is the same as the processing in steps S1 to S3 in FIG. 10, so that the detailed description is omitted.
If the image processing unit 51 of the processing unit 202 determines that the traveling vehicle is the target vehicle (step S53),
The wireless signal processing unit 52 and the sensor signal processing unit 221 are notified.

Next, in step S54, the sensor signal processing unit 221 controls the exhaust gas sensor 201 to
The measurement of the degree of light scattering is started.

The processing in steps S55 to S61 is the same as the processing in steps S4 to S10 in FIG. 10, and therefore detailed description is omitted. When it is determined that the vehicle does not satisfy the traffic condition, the process proceeds to step S62, and based on the detection result of the light scattering degree started to be measured in step S54, the harmful substance contained in the exhaust gas of the traveling vehicle is set to the standard. It is determined whether or not the value is equal to or greater than the value. When it is determined that the value is greater than or equal to the value, the process proceeds to step S63, where it is determined that the traveling vehicle does not satisfy the traffic condition, and a predetermined process is executed.

If it is determined in step S62 that the value is equal to or less than the reference value, step S63 is skipped by the processing in steps S53, S60 and S61 as in the case where it is determined that the traveling vehicle satisfies the traffic condition. And the process ends.
