Description

The present invention relates to hydrogen filling systems.

In recent years, attention has been focused on fuel cells, which are clean and have high energy efficiency, as a drive source for vehicles. A fuel cell vehicle using a fuel cell as a drive source runs by driving a motor using electric power generated by the fuel cell. At this time, the fuel cell generates electricity through a chemical reaction between hydrogen, which is a fuel gas, and oxygen in the air, which is an oxidant gas, and thus consumes hydrogen in accordance with the amount of electricity generated. Therefore, a fuel cell vehicle equipped with a fuel cell is equipped with a hydrogen tank capable of being filled with a predetermined amount of hydrogen.

In order to utilize fuel cell vehicles, a hydrogen filling facility is required to fill the hydrogen tank of the fuel cell vehicle with hydrogen. The hydrogen filling equipment is provided with a hydrogen filling nozzle, and the fuel cell vehicle is provided with a hydrogen filling port to which the hydrogen filling nozzle can be connected. When actually filling the hydrogen tank of the fuel cell vehicle with hydrogen, the hydrogen filling nozzle is inserted into the hydrogen filling port of the fuel cell vehicle and connected, and the hydrogen tank is filled with hydrogen through this connecting portion.

When filling the hydrogen tank of a fuel cell vehicle with hydrogen using a hydrogen filling facility, predetermined information is exchanged via wireless communication between the facility side control unit that controls the hydrogen filling facility and the vehicle side control unit that controls the fuel cell vehicle. A filling control method called communication filling is known, in which hydrogen filling is controlled by using a fuel cell (see, for example, Patent Literature 1).

By the way, a fuel cell vehicle needs to be filled with hydrogen as a fuel, and there are at least two types (plurality) of hydrogen filling pressures to be applied when hydrogen is filled depending on the type of vehicle to be filled. At present, fuel cell vehicles with different hydrogen filling pressures are roughly classified into fuel cell vehicles in which the hydrogen tank is filled with hydrogen at high pressure and fuel cell industrial vehicles in which hydrogen is filled at a lower pressure than the fuel cell vehicles. Fuel cell vehicles are vehicles such as ordinary vehicles, buses, trucks, etc. that are equipped with fuel cells. Fuel cell industrial vehicles are industrial vehicles such as forklifts and towing vehicles (tractors) equipped with fuel cells. Generally, the hydrogen filling pressure applied to fuel cell vehicles is 70 MPa, and the hydrogen filling pressure applied to fuel cell industrial vehicles is 35 MPa.

The difference in hydrogen filling pressure affects the temperature rise of the hydrogen tank due to adiabatic compression during hydrogen filling. That is, if the hydrogen filling pressure is high, the temperature of the hydrogen tank tends to rise during hydrogen filling. Therefore, in a hydrogen filling facility for a fuel cell vehicle with a high hydrogen filling pressure, hydrogen filling is controlled while controlling the temperature of the hydrogen tank during hydrogen filling. Specifically, the hydrogen tank temperature is detected on the fuel cell vehicle side, and the detection result is sent from the fuel cell vehicle side to the hydrogen filling equipment side by means of a communication function, thereby controlling the hydrogen filling speed, etc. are doing. In such a hydrogen filling facility for a fuel cell vehicle with a high hydrogen filling pressure, a communication function is used between the fuel cell vehicle and the hydrogen filling facility to transmit and receive information to control hydrogen filling. Therefore, in a hydrogen filling facility for a fuel cell vehicle with a high hydrogen filling pressure, a fuel cell vehicle that does not have a communication function is not filled with hydrogen.

On the other hand, in hydrogen filling facilities for fuel cell industrial vehicles with low hydrogen filling pressure, if the temperature of the hydrogen tank does not need to be strictly controlled during hydrogen filling, the temperature of the hydrogen tank of the fuel cell industrial vehicle is predetermined. hydrogen is filled at the same filling speed. Therefore, the hydrogen filling equipment for fuel cell industrial vehicles does not need to exchange information for hydrogen filling control between the vehicle and the hydrogen filling equipment during hydrogen filling, and is not provided with such a communication function. There is

In this way, the hydrogen filling equipment for fuel cell vehicles with a communication function has a communication function to communicate with the vehicle side, so it is possible to prevent erroneous filling depending on the presence or absence of the communication function in the hydrogen filling target vehicle. . However, in hydrogen filling facilities for fuel cell industrial vehicles that do not have a communication function, it is necessary to prohibit hydrogen filling when the hydrogen filling nozzle is connected to the hydrogen filling port of the fuel cell vehicle.

The present invention has been made in order to solve the above problems, and its object is to provide a hydrogen filling facility for fuel cell industrial vehicles, in which hydrogen is supplied incorrectly to fuel cell vehicles having a hydrogen filling pressure different from that of fuel cell industrial vehicles. To provide a hydrogen filling system capable of preventing filling.

The present invention provides a hydrogen filling facility capable of filling a hydrogen tank mounted on a fuel cell vehicle with hydrogen, a camera for photographing the fuel cell vehicle located near the hydrogen filling facility, and the image of the fuel cell vehicle photographed by the camera. and a control device that uses an image to instruct the hydrogen filling facility to permit or disallow hydrogen filling, the hydrogen filling facility is a hydrogen filling facility for fuel cell industrial vehicles, and the control device uses a camera. a determination unit that determines whether the fuel cell vehicle corresponds to a fuel cell industrial vehicle or a non-fuel cell industrial vehicle by image recognition processing using a photographed image of the fuel cell vehicle; , a mast, a fork, a counterweight, and a tractor installed in a fuel cell industrial vehicle are extracted as characteristics of the fuel cell industrial vehicle, and if an element matching the characteristics is included in the image of the fuel cell industrial vehicle, the fuel cell If the vehicle corresponds to a fuel cell industrial vehicle and the image does not contain an element that matches the characteristics, it is determined that the fuel cell vehicle corresponds to a non-fuel cell industrial vehicle. Only when is applicable to a fuel cell industrial vehicle, an instruction to permit hydrogen filling is given to the hydrogen filling facility.

The nozzle attachment/detachment sensor 41 is a sensor that detects the attachment/detachment state of the hydrogen filling nozzle 36 . The nozzle attachment/detachment sensor 41 is turned off when the hydrogen filling nozzle 36 is attached to the predetermined position of the hydrogen filling equipment 11, and turned on when the hydrogen filling nozzle 36 is removed from the predetermined position of the hydrogen filling equipment 11. . The on-off valve drive unit 42 opens and closes the on-off valve provided in the hydrogen supply path from the hydrogen storage tank to the hydrogen filling hose 34 . When the on-off valve drive unit 42 opens the on-off valve, hydrogen is supplied from the hydrogen storage tank to the hydrogen filling hose 34. When the on-off valve drive unit 42 closes the on-off valve, hydrogen is supplied from the hydrogen storage tank. No hydrogen is supplied to the hydrogen filling hose 34 .

The control device 52 includes a sensing portion 55 that senses stoppage of the vehicle, a determination portion 56 that determines the type of vehicle, and a control signal output portion 57 that outputs the control signal based on the determination result of the determination portion 56. ing. The sensing unit 55 senses that the fuel cell vehicle 12 has stopped in the predetermined area 33 based on the image captured by the camera 51 . Camera 51 captures a wide field of view including predetermined area 33 . When the fuel cell vehicle 12 moves within the field of view of the camera 51, the sensing unit 55 monitors the movement (running state) of the fuel cell vehicle 12 using the image data transmitted from the camera 51. When the movement of the fuel cell vehicle 12 stops in the predetermined area 33 at this time, it is recognized that the fuel cell vehicle 12 has stopped in the predetermined area 33 .

The determining unit 56 performs image recognition processing using the image of the fuel cell vehicle captured by the camera 51 to determine whether or not the fuel cell vehicle located in the predetermined area 33 corresponds to the fuel cell industrial vehicle ( hereinafter, also referred to as “discrimination processing”). The types of vehicles discriminated by the discrimination unit 56 include fuel cell industrial vehicles and non-fuel cell industrial vehicles. The determination unit 56 determines the type of vehicle by image recognition using artificial intelligence. In image recognition using artificial intelligence, a predetermined number of image data of fuel cell industrial vehicles are input, and the features of fuel cell industrial vehicles are extracted from the image data using machine learning or deep learning. Then, when image data including an image of the fuel cell vehicle to be determined is transmitted from the camera 51 to the control device 52, the determination unit 56 determines whether the image of the fuel cell vehicle included in the image data contains fuel. If the fuel cell vehicle includes an element that matches the characteristics of the battery industrial vehicle, it is determined that the fuel cell vehicle corresponds to the fuel cell industrial vehicle.

In image recognition using artificial intelligence, the following features can be cited as features extracted from image data of fuel cell industrial vehicles. That is, in the case of the fuel cell vehicle (forklift) 12 shown in FIG. are characteristic. In the case of a towing vehicle (traction vehicle), it is characterized by the presence of a traction machine at the rear of the vehicle.

The control signal output section 57 outputs a control signal for controlling hydrogen filling according to the determination result of the determination section 56 . Control signals for controlling hydrogen filling include a control signal for permitting hydrogen filling (hereinafter referred to as "hydrogen filling permission signal") and a control signal for disallowing (prohibiting) hydrogen filling ( hereinafter referred to as "hydrogen filling disapproval signal"). Which control signal the control signal output unit 57 outputs is determined by the determination result of the determination unit 56 . That is, when the determination unit 56 determines that the fuel cell vehicle located in the predetermined area 33 corresponds to the fuel cell industrial vehicle, the control signal output unit 57 instructs the hydrogen filling facility 11 to permit hydrogen filling. Therefore, a hydrogen filling permission signal is output to the hydrogen filling equipment 11 . Further, when the determination unit 56 determines that the fuel cell vehicle located in the predetermined area 33 does not correspond to the fuel cell industrial vehicle, the control signal output unit 57 instructs the hydrogen filling facility 11 not to allow hydrogen filling. is output to the hydrogen filling equipment 11.

Next, the processing and operations performed by the fuel cell system according to the embodiment of the present invention will be described with reference to FIG.
First, the control device 52 uses the image data transmitted from the camera 51 to determine whether or not the fuel cell vehicle has stopped in the predetermined area 33 near the hydrogen filling facility 11 (step S1). This determination is made by the sensing section 55 . When the sensing unit 55 determines that the fuel cell vehicle has stopped in the predetermined area 33, the hydrogen filling facility 11 determines whether the hydrogen filling nozzle 36 has been removed by the operator based on the ON/OFF state of the nozzle attachment/detachment sensor 41. (step S2). Specifically, if the nozzle attachment/detachment sensor 41 remains off, No is determined in step S2, and if the nozzle attachment/detachment sensor 41 is switched from off to on, it is determined Yes in step S2. After removing the hydrogen filling nozzle 36 from a predetermined position of the hydrogen filling facility 11 , the operator inserts the hydrogen filling nozzle 36 into the hydrogen filling port 22 of the fuel cell vehicle 12 for connection.

Next, in the hydrogen filling facility 11, it is determined whether or not the hydrogen filling start button 39 has been pressed by the operator (step S3). Then, when a notification signal indicating that the hydrogen filling start button 39 has been pressed is sent from the hydrogen filling facility 11 to the control device 52, the determining section 56 takes in the image data taken by the camera 51 (step S4). At this time, the image data captured by the camera 51 includes an image of the fuel cell vehicle stopped in the predetermined area 33 . FIG. 2 shows a state in which the fuel cell vehicle 12, which is a forklift, is stopped in a predetermined area 33. As shown in FIG.

Next, the determining unit 56 performs image recognition processing using the image data of the fuel cell vehicle photographed by the camera 51 in step S4 to determine that the fuel cell vehicle located in the predetermined area 33 corresponds to the fuel cell industrial vehicle. It is determined whether or not (step S5). If the determination result indicates that the fuel cell vehicle located in the predetermined region 33 corresponds to the fuel cell industrial vehicle, that is, if it is determined as Yes in step S5, the control signal output unit 57 outputs the hydrogen filling permission signal. Output to the facility 11 (step S6). As a result, in the hydrogen filling equipment 11, the on-off valve drive section 42 opens the on-off valve, so that the hydrogen tank 21 starts to be filled with hydrogen through the connecting portion between the hydrogen filling nozzle 36 and the hydrogen filling port 22 (step S7 ).

On the other hand, when the fuel cell vehicle located in the predetermined area 33 does not correspond to the fuel cell industrial vehicle in the determination result by the determination unit 56, that is, when it is determined as No in step S5, the control signal output unit 57 A hydrogen filling disapproval signal is output to the hydrogen filling equipment 11 (step S8). As a result, in the hydrogen charging equipment 11, the on-off valve driving unit 42 keeps the on-off valve closed, so that hydrogen filling does not start and an error message is displayed on the screen of the touch panel 38 (step S9 ). On the screen of the touch panel 38, it is preferable to display an error message such as "This vehicle is not a vehicle for which hydrogen filling is permitted. Please return the hydrogen filling nozzle to its original position and move the vehicle immediately." . As a result, hydrogen filling can be permitted for fuel cell industrial vehicles, and hydrogen filling can be prohibited for non-fuel cell industrial vehicles.

As described above, in the embodiment of the present invention, the camera 51 is provided for capturing an image of the fuel cell vehicle 12 located near the hydrogen filling facility 11 (predetermined area 33). Using the image, the determining unit 56 determines whether the fuel cell vehicle 12 corresponds to the fuel cell industrial vehicle. Only when the fuel cell vehicle 12 located near the hydrogen filling facility 11 corresponds to the fuel cell industrial vehicle, the hydrogen filling facility 11 is instructed to permit hydrogen filling. As a result, in the hydrogen filling facility 11 for fuel cell industrial vehicles, the filling of hydrogen to fuel cell vehicles, which are non-fuel cell industrial vehicles, is prohibited. Therefore, in the hydrogen filling facility 11 for fuel cell industrial vehicles, erroneous filling of hydrogen into the hydrogen tank of the fuel cell vehicle can be prevented. In addition, in this embodiment, since there is no need to add any parts or functions to the fuel cell vehicle, the vehicle cost is not affected, and fuel cell vehicles that have already been sold or fuel cell vehicles made by different manufacturers can be used. A subject can be determined to be allowed or disallowed to fill with hydrogen.

Further, in the embodiment of the present invention, when the hydrogen filling start button 39 of the hydrogen filling facility 11 is pressed, the determination unit 56 captures the image of the fuel cell vehicle 12 photographed by the camera 51 and performs determination processing. configuration is adopted. As a result, the fuel cell vehicle 12 located in the predetermined region 33 can be photographed by the camera 51 immediately before hydrogen filling is started, and the image of the fuel cell vehicle 12 can be used for determination processing.

Moreover, in the embodiment of the present invention, a configuration is adopted in which a sensing unit 55 senses that the fuel cell vehicle 12 has stopped near the hydrogen filling facility 11 based on the image captured by the camera 51 . This eliminates the need to use a dedicated sensor (for example, proximity sensor, weight sensor, etc.) to sense that the fuel cell vehicle 12 has stopped near the hydrogen filling facility 11, thereby simplifying the system configuration. can be done.

It should be noted that the technical scope of the present invention is not limited to the above-described embodiments, and includes forms with various modifications and improvements within the range where specific effects obtained by the constituent elements of the invention and their combinations can be derived. .

For example, in the above embodiment, when the hydrogen filling start button 39 of the hydrogen filling facility 11 is pressed, the image of the fuel cell vehicle 12 photographed by the camera 51 is captured by the determination unit 56 and the determination process is performed. Although adopted, the present invention is not limited to this. That is, it is also possible to perform the photographing by the camera 51 and the discrimination processing by the discriminating section 56 in the period from the detection of the stopping of the vehicle in step S1 to the detection of removal of the hydrogen filling nozzle 36 in step S2. . However, in that case, after the control signal output unit 57 outputs the hydrogen filling permission signal or the hydrogen filling non-permission signal, the fuel cell vehicle moves from the predetermined area 33, and then another fuel cell vehicle moves to the predetermined area. 33, and in that case, it is necessary to redo the photographing by the camera 51 and the discrimination processing by the discriminating section 56 again. Therefore, when the hydrogen filling start button 39 of the hydrogen filling facility 11 is pressed, it is preferable to perform photographing by the camera 51 and determination processing by the determination unit 56 .

Further, in the above embodiment, image data of fuel cell industrial vehicles are input and characteristics are extracted in order to determine the type of vehicle by image recognition. Image data may be input and its features extracted. Further, both the image data of the fuel cell industrial vehicle and the image data of the non-fuel cell industrial vehicle may be input to extract respective features.
