Referring to fig. 2, the infrared emission module 5 may include a fixing ring 52 of an integrated structure and a case 51 disposed on the fixing ring 52; a nameplate 53 may be further provided on the housing 51, and the nameplate 53 may be fixed to the housing 51 by caulking, bonding, or the like.

Referring to fig. 3, the housing 51 has a cavity structure therein, and the cavity structure includes a first chamber 61 disposed at a front end and a second chamber 62 disposed at a rear end of the first chamber 61. Specifically, the housing cavity may be divided into a first chamber 61 at the front end and a second chamber 62 at the rear end by an infrared communication board 515 disposed in the housing cavity. Referring to fig. 3, the cross-section of the housing is in an "L" shape, and the second chamber 62 may be present protruding from the first chamber 61. In the second chamber 62, a mounting hole may be started, in which a waterproof connector 511 is mounted. A step may be formed on the inner wall of the housing 51 in the first chamber 61, and an infrared communication board 515 may be mounted on the step, the infrared communication board 515 being electrically connected to the connector 511. A lens 518 is arranged on the infrared communication board 515; an infrared transmitting tube 516 is arranged in the lens 518, and the infrared transmitting tube 516 is fixed on the infrared communication board 515 and is electrically connected with the infrared communication board 515; the lens 518 serves as a mask for the infrared emission tube 516, and is disposed over the infrared emission tube 516.

In a general state, when the hydrogenation port cover 4 is closed, the hydrogenation proximity switch 7 outputs a low level signal, and the infrared sending module 5 enters a standby low power consumption mode. When the hydrogen energy is needed to be added to the vehicle, the hydrogenation port cover 4 on the filling port 3 is opened, the hydrogenation proximity switch 7 is triggered to be opened, a high-level signal is output, and the infrared emission component 5 is activated to enter a working mode. The infrared transmitting module 5 analyzes vehicle information on the CAN bus through an OBD interface of the whole vehicle, acquires information such as real-time hydrogen pressure, hydrogen temperature, hydrogen concentration value in the vehicle, rated hydrogen pressure and the like, and transmits the information to the infrared receiving component 1. The infrared receiving assembly 1 receives real-time information and transmits the current real-time information of the automobile to a server side of a background of the hydrogen station, and a worker can control the hydrogen gun system at the server side to realize automatic hydrogen addition or finish hydrogen addition and present the information to the worker or a user of the hydrogen station.

In the filling process, the server side can perform real-time fault judgment according to the vehicle information received in real time. If the phenomena of temperature abnormality, pressure abnormality or hydrogen concentration abnormality and the like of the vehicle are judged, the server side can control the hydrogenation gun to stop filling hydrogen in an emergency. And the hydrogen adding station worker also judges whether the hydrogen adding of the vehicle is finished or not and whether the hydrogen concentration is too high or not and the hydrogen leakage condition exists or not according to the current vehicle information, and manually finishes the hydrogen adding state. In the normal filling process, when the hydrogen pressure of the vehicle received by the hydrogenation station server end is close to the rated pressure, the background of the hydrogenation station judges that the hydrogenation is finished, and the hydrogenation gun is controlled to be closed. After the hydrogenation port cover 4 of the filling port is closed, the hydrogenation proximity switch outputs a low level, and the infrared sending module enters a standby low-power-consumption mode.

If the vehicle-mounted main control cannot work, the infrared transmitting module cannot work, and the infrared transmitting module cannot analyze the state information of the vehicle hydrogen system, and after the hydrogenation gun is connected with the vehicle hydrogenation port for 5 seconds, no effective information is received, and the infrared receiving module is judged to be overtime. At the moment, the hydrogenation process is converted into a traditional hydrogenation mode, and the hydrogenation station worker manually hydrogenates and judges whether hydrogenation is finished or not.

According to the hydrogen energy filling device provided by the disclosure, the infrared transmitting component is connected to the OBD interface only through the CAN, and the existing vehicle electrical device is not required to be changed; the infrared transmitting component only receives and analyzes data of the CAN bus, and does not influence the vehicle bus communication. And the working state of the infrared transmitting assembly can be switched by adding a proximity switch at the position of the car hydrogenation port cover. The infrared receiving module transmits the received vehicle real-time information to the background server of the hydrogenation station, so that the hydrogenation gun can be controlled to be switched on and off at the background server, automatic hydrogenation is realized according to the state of a vehicle hydrogen system, and the hydrogenation is automatically turned off.
