Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer to Figures 1-3 As shown, the present invention provides a hydrogen system pressure reducing valve controller, including an equipment box 1 with a box cover 9 hinged on one side of the top and a connecting wire 7 for connecting the equipment box 1 with the bottle mouth valve, electromagnetic pressure reducing valve and pressure sensor of a hydrogen cylinder. A partition 2 is arranged in the inner cavity of the equipment box 1. The partition 2 divides the inner cavity of the equipment box 1 into an operation cavity 11 and an equipment cavity 12 up and down. A wiring socket 31 is arranged on the side wall of the equipment cavity 12. A display component 41 is arranged on the partition 2. A main controller 5 for controlling the wiring socket 31 and the display component 41 and a power supply 6 for power supply are arranged in the equipment cavity 12. A first control switch 32 for controlling the wiring socket 31 and a second control switch 42 for controlling the display screen 51 are arranged on the partition 2;
[0029] Specifically, the wiring socket 31 includes a bottle mouth valve socket 311, an electromagnetic pressure reducing valve socket 312 and a pressure sensor socket 313. The first control switch 32 includes a bottle mouth valve switch 321 and an electromagnetic pressure reducing valve switch 322. The bottle mouth valve socket 311 is electrically connected to the main controller 5 through the bottle mouth valve switch 321. The electromagnetic pressure reducing valve socket 312 is electrically connected to the pressure regulating main controller 5 through the electromagnetic pressure reducing valve switch 322. The pressure sensor socket 313 is electrically connected to the main controller 5;
[0030] The display component 41 includes a power supply display screen 411 and a pressure gauge 412. The second control switch 42 includes a power supply display screen switch 421 and a pressure gauge switch 422. The power supply display screen switch 421 is electrically connected to the main controller 5 through the power supply display screen switch 421. The pressure gauge 412 is electrically connected to the main controller 5 through the pressure gauge switch 422.
[0031] A main switch 8 is provided on the partition plate 2, and the main switch 8 is electrically connected to the power supply 6 and the main controller 5 respectively.
[0032] When in use, turn on the main switch 8 to energize the main controller 5. If it is necessary to repair the bottle mouth valve, connect the two ends of the connection wire 7 to the bottle mouth valve socket 311 and the bottle mouth valve respectively, and then turn on the bottle mouth valve switch 321 to energize and open a single bottle mouth valve for repair; when repairing the electromagnetic pressure reducing valve, connect the two ends of the connection wire 7 to the electromagnetic pressure reducing valve socket 312 and the electromagnetic pressure reducing valve respectively, and then turn on the electromagnetic pressure reducing valve switch 322. Then connect the two ends of another connection wire 7 to the pressure sensor socket 313 and the low-pressure pressure sensor at the pressure reducing valve end respectively. After turning on the pressure gauge switch 422, its data parameters are displayed by the pressure gauge 412. Since generally buses adopt a design of 8 hydrogen cylinders in parallel in a group, when the vehicle is powered on and the bottle mouth valves are controlled, the 8 hydrogen cylinder bottle mouth valves will act simultaneously. The separate power-on control of the bottle mouth valve or the electromagnetic pressure reducing valve can reduce the interference to the vehicle hydrogen system, improve the repair efficiency, and at the same time, there is no need to power on the whole vehicle to reduce the repair risk;
