<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, a toll collection device 30, and a dew condensation generating device 70, as shown in FIG. The toll collection system 1 is a system in which a monitoring device 20 transmits an on signal to a toll collection device 30 having a defroster that is activated in response to a 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 traveling route 60 and photographing the dew condensation generating device 70 provided around the toll collection device 30. 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. Further, the photographing unit 101 photographs the dew condensation generating device 70 provided around the toll collection device 30. Note that the photographing unit 101 may photograph the condensation generating device 70 at the same time as the driving path 60. Further, for example, the photographing unit 101 may have a mechanism for changing the photographable range, or may be attached to an arm having such a mechanism to change the photographing range.

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). Note that switching the defroster 102 between the on state and the off state, that is, sending an on signal and an off signal to the defroster, may be manually performed by the collection staff.

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 is an image in which water droplets or cloudiness can be confirmed on the first member 70a, which will be described later, or a change in the color of the second member 70b, which will be described later, the collector can identify the image as indicating dew condensation. It is determined that

The remote control unit 202 can remotely control the toll collection device 30 and the photographing device 10. For example, the remote control unit 202 transmits an on signal to the toll collection device 30 when dew condensation occurs on the first member photographed by 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. The off signal is sent when the reading success rate exceeds a predetermined threshold, and may also be activated by a collection worker or a timer and then stopped after a predetermined period of time. The predetermined time may be set as different lengths for the monitoring device and the toll collection device.

The determining unit 203 determines whether or not dew condensation has occurred on the first member 70a photographed by the photographing device 10. For example, a collector determines via the display device 201 at least one of whether there are water droplets or cloudiness on the first member 70a photographed by the photographing device 10, and whether the color of the second member 70b has changed. do. If the collector determines that dew condensation has occurred on the first member photographed by the photographing device 10, 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 no condensation has occurred on the first member 70a photographed by the photographing device 10, 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.

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 housing 30a. Further, as shown in FIG. 5, the toll collection device 30 includes a reception section 301 (an example of a portion where condensation is detected), an accounting processing section 302, and a defroster 303.

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. Condensation may occur in the toll collection device 30. For example, in the reception section 301, 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 toll collection device 30 When wind blows on the surface of the toll collection 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).

The dew condensation generating device 70 includes a first member 70a and a second member 70b. The condensation generating device 70 is installed in a position that can be considered to be in the same environment as the reception section 301 of the toll collection device 30. For example, the dew condensation generator 70 is installed at the top of the casing 30a of the toll collection device 30.

The first member 70a is a member that generates dew condensation when it comes into contact with air whose temperature is higher than that of the first member 70a. The first member 70a is a member with high thermal conductivity, such as copper. Note that the first member 70a is preferably a member having a thermal conductivity higher than that of the receiving section 301 of the toll collection device 30. This means that when the first member 70a has a thermal conductivity higher than that of the receiving section 301 and the first member 70a and the receiving section 301 exist under the same environment, the first member 70a has a higher thermal conductivity than the receiving section 301. This is based on the idea that the member 70a is under conditions where dew condensation occurs earlier. In other words, by making the first member 70a a member having a thermal conductivity higher than that of the receiving section 301, there is a possibility that condensation will occur on the receiving section 301 at the latest by the timing when condensation occurs on the receiving section 301. It can be detected that there is.

The first member 70a is installed in such a direction that the portion where dew condensation occurs (that is, the portion that comes into contact with warmer air than the first member 70a) can be photographed by the photographing device 10. Note that when the first member 70a is fixed, the photographing device 10 can photograph the position where dew condensation occurs in warm air in the opposite direction to the direction in which the photographing device 10 photographs the first member 70a. I can't. For example, if the first member 70a is a flat copper plate and warm air touches the copper plate in a direction opposite to the direction in which the imaging device 10 photographs the first member 70a, dew condensation will occur in the opposite direction to the direction in which the imaging device 10 photographs the first member 70a. Occurs on the surface. Therefore, the photographing device 10 cannot photograph the dew condensation. In this way, in order to prevent the photographing device 10 from being unable to photograph the dew condensation on the first member 70a, the first member 70a may be rotated by 180 degrees at certain time intervals, for example. In addition, in order to prevent the photographing device 10 from being unable to photograph the dew condensation on the first member 70a, for example, a mirror that can reflect the back surface and check it from the photographing device 10 side is provided. Good too.

Note that when the photographing device 10 and the toll collection device 30 are in the positional relationship as shown in FIG. 1, for example, and the first member 70a is a flat copper plate, the first member 70a is , is installed in the toll collection device 30 so that one side of the copper plate faces the photographing device 10 side and is diagonal to the direction of the travel path 60.

The second member 70b is a material that changes color in response to water droplets or cloudiness when condensation occurs. This second member 70b makes it easier to recognize the occurrence of dew condensation. For example, the second member 70b is a member containing cobalt chloride. The second member 70b is installed, for example, on the side of the first member 70a on which gravity acts. For example, when gravity is acting from above to below the toll collection device 30, the second member 70b is provided below the first member 70a, as shown in FIG. Note that the second member 70b may be a sheet-like member that is attached to the first member 70a. Further, the second member 70b may be configured by being applied to the first member 70a, for example.

(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 303 by the monitoring device 20 will be described with reference to FIG. It is assumed that the photographing device 10 is located within a distance that allows photographing the toll collection device 30 and the dew condensation generating device 70.

For example, when air that is warmer than the surface of the first member 70a hits the surface of the first member 70a and is cooled, dew condensation occurs on the surface of the first member 70a. Further, in this case, the generated dew drops due to gravity and wets the second member 70b, thereby changing the color of the second member 70b. The display device 201 displays at least one image of dew condensation on the first member 70a and a change in color of the second member 70b photographed by the photographing device 10. The collection worker looks at the image displayed on the display device 201 and determines that condensation has occurred if water droplets or cloudiness are seen on the first member 70a or if the color of the second member 70b has changed. 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 transmits an on signal to the toll collection device 30 (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.

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 S4). 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 S4), the process returns to step S4. Further, 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 equal to or higher than a predetermined threshold (YES in step S4), the remote control unit 202 transmits an off signal to the defroster provided in the toll collection device 30. 303 (step S5). The defroster 303 stops operating in response to the off signal (step S6).

(effect)
The toll collection system 1 according to the first embodiment of the present disclosure has been described above. The toll collection system 1 is a toll collection device 30 installed on the roadside of a travel path 60 on which a vehicle 40 travels, and includes a defroster 303 that is activated in response to a received ON signal; It has an operation control unit 202 that transmits the on signal to the toll collection device 30 when dew condensation occurs in the first member 70a.

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, by regarding the occurrence of dew condensation on the first member 70a as the occurrence of dew condensation on the toll collection device 30, the toll collection system 1 can determine the occurrence of dew condensation on the toll collection device 30.

<Second embodiment>
In the first embodiment of the present disclosure, the collector determines whether or not dew condensation has occurred on the first member 70a, and the determination unit 203 determines whether or not condensation has occurred on the first member 70a based on the determination result determined by the collector. The explanation has been given as determining whether or not an event has occurred. However, in the second embodiment of the present disclosure, the determination unit 203 determines whether or not condensation has occurred in the first member 70a using a learned model whose parameters have been determined by supervised learning using teacher data. It may be something to judge.
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 was used when the collector determined whether or not dew condensation had occurred on the first member 70a. 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 on the first member 70a 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 the image data photographed by the photographing device 10 (that is, data indicating whether or not dew condensation has occurred on the first member 70a) constitutes one set of data. In the example shown in FIG. 8, 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. 8, then 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 8, 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 8 for even one of the test data, new training data is 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.

Each of the storage units and storage devices (including registers and latches) in the embodiments of the present disclosure may be provided anywhere as long as appropriate information is transmitted and received. Further, each of the storage units and storage devices may exist in plurality and store data in a distributed manner within a range where appropriate information is transmitted and received.

In the first embodiment of the present disclosure, the toll collection system 1 has been described on the assumption that the collection staff determines dew condensation by viewing an image taken by the photographing device 10 of the dew condensation generating device 70. However, in another embodiment of the present disclosure, a collector may directly view at least one of the first member 70a and the second member 70b to determine dew condensation. In this case, the dew condensation generating device 70 does not necessarily need to be installed at a position where it can be photographed by the photographing device 10, but may be installed at a position where the collection staff can check it.

In addition, in 1st Embodiment of this indication, the upper part of the toll collection apparatus 30 was mentioned and demonstrated as a specific example where the dew condensation generating apparatus 70 is installed. However, in another embodiment of the present disclosure, the location where the condensation generating device 70 is installed is, for example, a location where a roof is provided, such as a section where a vehicle detector is provided when the toll road is an expressway. It may be. This can prevent the dew condensation generating device 70 from getting wet due to rain or the like and becoming unable to detect the occurrence of dew condensation.

Note that in the first embodiment of the present disclosure, the first member 70a has been described using a planar shape as an example. However, the shape of the first member 70a may be such that dew condensation occurs in a location that is easily recognized not only from one direction but also from other directions, such as a sphere or a cylinder, for example.

In the second embodiment of the present disclosure, a method has been described in which the occurrence of dew condensation is determined using a trained model whose parameters are determined by supervised learning using an image of the first member 70a. However, in another embodiment of the present disclosure, the parameters are determined by supervised learning using an image of the second member 70b instead of or in addition to the image of the first member 70a. The occurrence of dew condensation may be determined based on a completed model.

Although the embodiment of the present disclosure has been described, the above-described toll collection system 1, photographing device 10, monitoring device 20, toll collection device 30, and other control devices may have a computer system inside. The above-described processing steps are stored in a computer-readable recording medium in the form of a program, and the above-mentioned processing is performed by reading and executing this program by the computer.

The computer 5 includes a CPU 6, a main memory 7, a storage 8, and an interface 9, as shown in FIG.
For example, each of the above-described toll collection system 1, photographing device 10, monitoring device 20, toll collection device 30, and other control devices is implemented in the computer 5. The operations of each processing section described above are stored in the storage 8 in the form of a program. The CPU 6 reads the program from the storage 8, expands it to the main memory 7, and executes the above processing according to the program. Further, the CPU 6 reserves storage areas corresponding to each of the above-mentioned storage units in the main memory 7 according to the program.

Examples of the storage 8 include HDD (Hard Disk Drive), SSD (Solid State Drive), magnetic disk, magneto-optical disk, CD-ROM (Compact Disc Read Only Memory), and DVD-ROM (Digital Versatile D). isc Read Only Memory) , semiconductor memory, etc. Storage 8 may be an internal medium directly connected to the bus of computer 5, or may be an external medium connected to computer 5 via interface 9 or a communication line. Further, when this program is distributed to the computer 5 via a communication line, the computer 5 that receives the distribution may develop the program in the main memory 7 and execute the above processing. In at least one embodiment, storage 8 is a non-transitory tangible storage medium.

Further, the program may realize some of the functions described above. Furthermore, the program may be a file that can realize the above-described functions in combination with a program already recorded in the computer system, a so-called difference file (difference program).

Although several embodiments of the disclosure have been described, these embodiments are examples and do not limit the scope of the disclosure. Various additions, various omissions, various substitutions, and various changes may be made to these embodiments without departing from the gist of the disclosure.
