<First embodiment>
Hereinafter, embodiments will be described in detail with reference to the drawings.
A toll collection system according to a first embodiment of the present disclosure will be described.
(Configuration of toll collection system)
FIG. 1 is a diagram showing the configuration of a toll collection system 1 according to a first embodiment of the present disclosure. The toll collection system 1 includes a photographing device 10, a monitoring device 20, and a toll collection device 30, as shown in FIG. The toll collection system 1 is a system in which an on signal is simultaneously transmitted from the monitoring device 20 to each of the toll collection device 30 and the photographing device 10, each of which has a defroster that becomes operational in response to the received on signal. Note that FIG. 1 shows a vehicle 40, an office 50, and a running path 60.

The photographing device 10 is a device for monitoring the driving route 60. The photographing device 10 includes a photographing section 101 and a defroster 102, as shown in FIG.

The photographing unit 101 is, for example, a camera. The photographing unit 101 photographs, for example, a traveling path 60 on which a vehicle 40 travels near where the toll collection device 30 is installed.

The defroster 102 becomes operational in response to the received ON signal. That is, the defroster 102 generates heat when receiving the on signal. Due to this heat generation, the dew condensation generated on the surface of the photographing device 10 is eliminated (disappeared).

In the photographing device 10, there is a possibility that dew condensation may occur. Condensation occurs when air at temperature It is generated when water vapor that can no longer be held in water changes to water. Therefore, for example, as shown in FIG. 3, the surface temperature (for example, the temperature of the lens surface) of the photographing device 10 placed in an environment where the temperature decreases from evening to night decreases, and the surface temperature of the photographing device 10 decreases. When wind blows that is warmer than the surface temperature, the wind hits the surface and the temperature decreases, potentially causing dew condensation on the surface of the photographing device 10. That is, by determining whether the image photographed by the photographing device 10 is an image when the lens is clouded, it is possible to determine whether or not condensation has occurred in the photographing device 10.

In addition, when the toll collection device 30 included in the toll collection system 1 is, for example, a toll collection device installed on the roadside of a toll road such as an expressway, the toll collection system 1 takes an image in the vicinity of the toll collection device 30. A device 10 is provided. That is, there is a high possibility that the photographing device 10 is already provided in the toll collection system 1, and it is unlikely that the photographing device 10 will be newly added. The photographing unit 101 in this case is, for example, an ITV (Industrial TeleVision) camera (surveillance camera). Note that in the embodiment of the present disclosure, the toll road includes a toll parking lot.

As shown in FIG. 4, the monitoring device 20 includes a display device 201, a remote control section 202 (an example of an operation control section, an example of a stop control section), a determination section 203, a button 204, and a button 205. The monitoring device 20 is installed in an office 50 shown in FIG. 1, for example. The monitoring device 20 is, for example, a monitoring board. The monitoring board displays the status of the tollgate to the watchman, and is operated by the watchman depending on the situation to accept and execute operations on the equipment at the tollgate.

The display device 201 can display images captured by the imaging device 10. At the office 50, a collection employee monitors whether the fee is being paid appropriately while checking the image taken by the photographing device 10 via the display device 201. Additionally, the collector monitors whether the image taken by the photographing device 10 is an image showing dew condensation. For example, if the image shows water droplets or cloudy weather, the collection worker determines that the image is indicative of dew condensation.

The remote control unit 202 can remotely control the toll collection device 30 and the photographing device 10. For example, when dew condensation occurs in the photographing device 10, the remote control unit 202 simultaneously transmits an on signal to the toll collection device 30 and the photographing device 10. Further, for example, the remote control unit 202 may be configured to provide the toll collection device 30 with an off signal that causes the toll collection device 30 to stop operating when the success rate of reading the object to be read by the toll collection device 30 exceeds a predetermined threshold. The signal is sent to the defroster 303. The reading success rate (percent) is expressed as (1-(number of reading failures/(number of reading successes+number of reading failures)))×100. Further, for example, when the condensation on the photographing device 10 is eliminated, the remote control unit 202 transmits an off signal to the defroster 102 included in the photographing device 10 .

The determining unit 203 determines whether or not dew condensation has occurred in the photographing device 10. For example, a collector determines whether the image taken by the photographing device 10 is cloudy or not via the display device 201. If the collector determines that the image taken by the photographing device 10 is cloudy, the collector presses the button 204 on the monitoring device 20, for example. In this case, a dew condensation occurrence signal indicating that dew condensation has occurred is transmitted to determination section 203. Furthermore, if the collector determines that the image taken by the photographing device 10 is not cloudy, the collector does not press the button 204 on the monitoring device 20, for example. In this case, the dew condensation occurrence signal is not transmitted to the determination section 203. That is, when the determination unit 203 receives the dew condensation occurrence signal, it determines that dew condensation has occurred. Furthermore, when the determination unit 203 does not receive a dew condensation occurrence signal, it determines that dew condensation is not occurring. When pressed, the button 204 transmits a dew condensation occurrence signal to the determination unit 203.

Further, the determining unit 203 determines whether or not dew condensation has been eliminated in the photographing device 10. For example, if the collection worker determines via the display device 201 that the image taken by the photographing device 10 has changed from a cloudy state to a cloudy state, the collection worker may, for example, press the button 205 on the monitoring device 20. Press down. In this case, a stop signal is sent to determination section 203. In addition to being operated by the collector, the stop signal may be operated by a timer and then stopped after a predetermined period of time, and the predetermined time may be set to a different length for the monitoring device and the toll collection device. You can. Further, if the collector determines through the display device 201 that the image captured by the photographing device 10 does not change from the cloudy state, the collector does not press the button 205. In this case, the stop signal is not sent to determination section 203. That is, when the determination unit 203 receives the stop signal, it determines that the condensation has been eliminated. Furthermore, when the determination unit 203 does not receive a stop signal, it determines that the condensation has not been eliminated. The button 205 transmits a stop signal to the determination unit 203 when pressed.

The toll collection device 30 collects tolls for vehicles 40 using toll roads. The toll collection device 30 is installed on the roadside of the road on which the vehicle 40 travels. The toll collection device 30 includes a reception section 301, an accounting processing section 302, and a defroster 303, as shown in FIG.

The reception unit 301 receives at least one of a toll for the vehicle 40 using the toll road and a ticket for the vehicle 40 using the toll road. In the toll collection device 30, similarly to the photographing device 10, there is a possibility that dew condensation may occur. Therefore, for example, the surface temperature of the toll collection device 30 placed in an environment where the temperature decreases from evening to night (for example, the temperature of the reading section on the surface of the reception section 301) decreases, and the reception section 301 stops toll collection. When wind blows on the surface of the device 30 that is warmer than the surface temperature, the wind hits the surface and the temperature decreases, potentially causing dew condensation on the surface of the toll collection device 30. In addition, when the reception part 301 accepts both a charge and a usage ticket, the reception part 301 may consist of two reception parts, one for a charge and one for a usage ticket.

The accounting processing unit 302 processes the toll for the vehicle 40 using the toll road based on at least one of the toll and the ticket received by the reception unit 301. For example, the accounting processing unit 302 issues a receipt indicating the fee.

The defroster 303 becomes operational in response to the received ON signal. That is, the defroster 102 generates heat when receiving the on signal. Due to this heat generation, the condensation generated on the surface of the toll collection device 30 is eliminated (disappeared).

(Processing performed by toll collection system 1)
Next, control of the toll collection device 30 and the photographing device 10 by the monitoring device 20 in the toll collection system 1 will be explained. Here, the operation of the defroster 102 and the defroster 303 by the monitoring device 20 will be described with reference to FIG. Note that, as described above, since the photographing device 10 exists within a distance that allows photographing the toll collection device 30, in the embodiment of the present disclosure, the conditions under which the photographing device 10 condenses are set to the toll collection device 30. is considered a condition that causes condensation. That is, in the embodiment of the present disclosure, when it is determined that dew condensation has occurred in the photographing device 10, it is assumed that dew condensation has occurred in the toll collection device 30 as well.

For example, when air that is warmer than the surface of the photographing device 10 hits the surface of the photographing device 10 and is cooled, dew condensation occurs on the surface of the photographing device 10. In this case, the image photographed by the photographing device 10 becomes cloudy. The display device 201 displays a cloudy image taken by the photographing device 10. The collector looks at the cloudy image displayed on the display device 201 and determines that condensation has occurred. If the collector determines that condensation has occurred, he or she presses the button 204. When pressed, the button 204 transmits a dew condensation occurrence signal to the determination unit 203. The determining unit 203 determines whether or not dew condensation has occurred in the photographing device 10 (step S1). When the determination unit 203 receives the dew condensation occurrence signal, it determines that dew condensation has occurred. Furthermore, when the determination unit 203 does not receive a dew condensation occurrence signal, it determines that dew condensation is not occurring.

If the determining unit 203 determines that no condensation has occurred (NO in step S1), the process returns to step S1. Further, when the determination unit 203 determines that dew condensation has occurred (YES in step S1), the remote control unit 202 simultaneously transmits an on signal to the toll collection device 30 and the photographing device 10 (step S2).

The defroster 303 of the toll collection device 30 operates in response to the ON signal from the remote control unit 202 (step S3). Specifically, the defroster 303 warms the toll collection device 30 including the reception section 301. This improves dew condensation in the reception section 301.

Further, the defroster 102 of the photographing device 10 operates in response to an on signal from the remote control section 202 (step S4). Specifically, the defroster 102 warms the photographing device 10 including the photographing section 101. This improves dew condensation in the imaging unit 101.

When the dew condensation in the photographing unit 101 is eliminated, the display device 201 displays a non-cloudy image photographed by the photographing device 10. The determination unit 203 determines whether or not dew condensation has been eliminated in the photographing device 10 (step S5). When the determination unit 203 receives the stop signal, it determines that the dew condensation has been eliminated. Furthermore, when the determination unit 203 does not receive a stop signal, it determines that the condensation has not been eliminated. When the cloudy image displayed on the display device 201 changes to a non-cloudy image, the collector determines that the condensation has been eliminated. When the collector determines that the condensation has been eliminated, the collector presses the button 205. The button 205 transmits a stop signal to the determination unit 203 when pressed.

If the determination unit 203 determines that the condensation has not been eliminated (NO in step S5), the process returns to step S5. Further, when the determination unit 203 determines that the dew condensation has been eliminated (YES in step S5), the remote control unit 202 transmits an off signal to the photographing device 10 (step S6). The defroster 102 stops operating in response to the off signal (step S7).

Further, the remote control unit 202 determines whether the reading success rate of the object to be read by the toll collection device 30 has exceeded a predetermined threshold (step S8). If the remote control unit 202 determines that the reading success rate of the object to be read by the toll collection device 30 is not equal to or higher than the predetermined threshold (NO in step S8), the process returns to step S8. Further, when it is determined that the reading success rate of the object to be read by the toll collection device 30 has become equal to or higher than a predetermined threshold (YES in step S8), the remote control unit 202 transmits an off signal to the defroster provided in the toll collection device 30. 303 (step S9). The defroster 303 stops operating in response to the off signal (step S10).

(effect)
The toll collection system 1 according to the first embodiment of the present disclosure has been described above. The toll collection system 1 includes a toll collection device 30 installed on the roadside of a traveling path 60 on which a vehicle 40 travels, a photographing device 10 for monitoring the traveling path 60, and an image taken by the photographing device 10 that can display images. , and a monitoring device 20 that can remotely control the toll collection device 30 and the photographing device 10. Each of the toll collection device 30 and the photographing device 10 has a defroster that becomes operational in response to the received ON signal. The monitoring device 20 has an operation control section that simultaneously transmits an on signal to the toll collection device 30 and the photographing device 10.

Thereby, the toll collection system 1 according to the first embodiment of the present disclosure can determine the occurrence of dew condensation in the toll collection device 30 with a simple configuration. That is, in many cases, the toll collection system 1 determines whether there is condensation on the toll collection device 30 by regarding the occurrence of condensation on the photographing device 10 included in the toll collection system 1 as the occurrence of condensation on the toll collection device 30. be able to.

<Second embodiment>
In the first embodiment of the present disclosure, the collector determines whether or not dew condensation has occurred in the photographing device 10, and the determination unit 203 determines whether or not condensation has occurred in the photographing device 10 based on the determination result determined by the collector. The explanation was given as determining whether or not the However, in the second embodiment of the present disclosure, the determination unit 203 determines whether or not condensation has occurred in the photographing device 10 using a trained model whose parameters have been determined by supervised learning using teacher data. It may be something that does.
The determination unit 203 determines whether or not condensation has occurred in the photographing device 10, for example, by using a learned model (for example, a convolutional neural network) whose parameters are determined by supervised learning, which is a type of machine learning. do. Here, the trained model used by the determination unit 203 for determination will be described.

(trained model)
Explain the trained model. In this case, one of the input data is, for example, past image data taken by the photographing device 10, which is used when the collector determines whether or not dew condensation has occurred in the photographing device 10. The past image data is an image whose result is known, whether it is an image when dew condensation occurs or an image when dew condensation does not occur. In addition, the output data is a past determination result by the collector indicating whether or not dew condensation has occurred in the photographing device 10 for each input data. In this way, based on past performance, it is possible to prepare teacher data consisting of a plurality of pieces of data that are combinations of input data and output data corresponding to each input data. Note that the teaching data is data used to determine parameter values in a learning model for which parameter values have not yet been determined.

FIG. 7 is a diagram showing an example of teacher data. Output data for image data photographed by the photographing device 10 (that is, data indicating whether or not dew condensation has occurred in the photographing device 10) constitutes one set of data. In the example shown in FIG. 7, the teacher data includes 10,000 sets of data.

For example, consider a case where parameters in a learning model are determined using teacher data consisting of 10,000 sets of data shown in FIG. In this case, the teacher data is divided into, for example, training data, evaluation data, and test data. Examples of the ratio of training data, evaluation data, and test data include 70%, 15%, 15%, 95%, 2.5%, and 2.5%. For example, assume that the teacher data of data #1 to #10000 is divided into data #1 to #7000 as training data, data #7001 to #8500 as evaluation data, and data #8501 to #10000 as 15% test data. In this case, data #1, which is training data, is input to a convolutional neural network, which is a learning model. The convolutional neural network outputs either the absence of condensation or the presence of condensation. Each time the input data of training data is input to the convolutional neural network, and the convolutional neural network outputs that no condensation has occurred or that condensation has occurred (in this case, each of data #1 to #7000 Each time data is input to a convolutional neural network), depending on its output, for example by backpropagating, the parameters that indicate the weighting of the data connections between nodes are changed (i.e., the model of the convolutional neural network change). In this way, training data is input into the neural network and parameters are adjusted.

Next, input data of evaluation data (data #7001 to #8500) is sequentially input to the convolutional neural network whose parameters have been changed according to the training data. The convolutional neural network outputs either no condensation or condensation, depending on the input evaluation data. Here, if the data output by the convolutional neural network is different from the output data associated with the input data in FIG. 7, the output of the convolutional neural network will be the output data associated with the input data in FIG. Change parameters. The convolutional neural network (ie, learning model) whose parameters have been determined in this manner is a trained model.

Next, as a final check, input data of test data (data #8501 to #10000) is input in order to the convolutional neural network of the trained model. The convolutional neural network of the trained model outputs either no condensation or condensation, depending on the input test data. For all test data, if the output data output by the convolutional neural network of the trained model matches the output data associated with the input data in Figure 7, then the convolutional neural network of the trained model is the desired model. It is. In addition, if the output data output by the convolutional neural network of the trained model does not match the output data associated with the input data in Figure 7 for even one of the test data, new training data will be used for learning. Determine model parameters. The above-described determination of the learning model parameters is repeated until a trained model with desired parameters is obtained. When a trained model having desired parameters is obtained, the trained model is recorded in a storage unit (not shown).

(effect)
By doing so, in the toll collection system 1 according to the second embodiment, the determination by the collector can be removed. As a result, the toll collection system 1 can reduce the labor of the collector and quickly perform the determination process.

Note that the order of the processing in the embodiment of the present disclosure may be changed as long as appropriate processing is performed.
