Description

The present invention relates to a gas filling system for filling a fuel tank or the like of a vehicle with a fuel gas such as hydrogen gas.

Fuel cell vehicles (FCVs) are being actively developed as vehicles that respond to recent environmental problems. For the further spread of fuel cell vehicles, regulations on hydrogen stations that supply fuel gas have been relaxed, the "self-service" that allows drivers who meet the conditions to fill hydrogen by themselves has been lifted, and the development of a safe and compact gas filling device. Was desired. Therefore, the applicant has proposed a gas filling device that is safe, compact, and has a high degree of design of the display unit (Patent Document 1).

Japanese Unexamined Patent Publication No. 2017-187057

Although the above invention is effective, the staff of the hydrogen station conducts the safety education necessary for the driver to fill the hydrogen by himself in a self-service manner. , There was a problem that other work could not be done. This could be a hindrance to the widespread use of "self-contained" hydrogen stations in the future.

In addition, even a driver who has received security education does not always remember how to operate it at the next filling, and if he is unfamiliar, he may perform the wrong operation, resulting in a serious accident. I couldn't deny it.

Therefore, the present invention has been made in view of the above-mentioned problems in the prior art, and the safety education can be carried out without the staff of the station, and the filling customer is unfamiliar with the filling work. However, it is an object of the present invention to provide a gas filling system capable of safely filling a fuel cell vehicle with fuel gas without making a mistake.

In order to achieve the above object, the present invention is a gas filling system, from an outdoor data input / output device that outputs a filling permission signal and displays safety education information regarding gas filling, and an outdoor data input / output device. It is characterized by being provided with a gas filling device that performs gas filling in response to a filling permission signal.

According to the present invention, since the security education information regarding gas filling is displayed on the outdoor data input / output device, the station staff can concentrate on the work other than the security education.

Further, the present invention is a gas filling system, in which an outdoor data input / output device that outputs a filling permission signal and displays safety education information regarding gas filling, and a filling permission signal are input from the outdoor data input / output device. It is characterized by comprising a POS and a plurality of gas filling devices that perform gas filling in response to a filling permission signal from the POS.

According to the present invention, the station staff can concentrate on work other than security education, and it becomes easy to manage slips at a station where a plurality of gas filling devices are installed.

In the gas filling system, the outdoor data input / output device reads from the input customer information whether or not the security education received by the customer is within the expiration date, and depending on the reading result, the security education information or the security education information or / And the operation guide can be displayed. If security education is not required, the filling time can be shortened by providing simple operation guidance.

By reading out the displayed security education information by voice, visual and auditory understanding is advanced, and security education can be efficiently implemented.

The display screen of the outdoor data input / output device is next until a certain time elapses after the displayed security education information is read out by voice, or until the last line of the displayed security education information is reached. By preventing the transition to the screen of, it is possible to surely inform the necessary information.

The expiration date of the security education can be determined from the security education expiration date information written in the slip issued when the security education received by the customer is completed.

Further, the expiration date of the security education is determined by the security education expiration date information written in the slip issued at the end of each filling of the customer, so that it is not necessary to carry the first issued slip forever. The risk of losing the slip is reduced. Further, when the security education expiration date information is printed on the thermal paper, it is possible to prevent the printing from becoming faint and undecidable due to long-term use.

As described above, according to the present invention, safety education can be carried out without the need for station staff, and even a customer who is unfamiliar with filling work can safely fill a fuel cell vehicle or the like with fuel gas without making a mistake. be able to.
