Among them, the mobile electrolytic hydrogen production mode can be dynamically placed in various places according to the seasonal changes of wind power or photovoltaic power abandonment, improve the efficiency of equipment use, and have higher flexibility and convenience. However, compared with traditional fixed electrolytic hydrogen production equipment, mobile electrolytic hydrogen production equipment also needs a series of adjustments and faces corresponding technical challenges.

When the equipment arrives at the site, it is necessary to achieve quick connection, installation and debugging. In terms of space utilization, mobile equipment usually has limited space. In terms of environmental adaptability, considering that the equipment may work under different environmental conditions, it is necessary to ensure that the signal is not affected by possible electromagnetic interference and retain the stability and continuity of the transmission signal.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with specific embodiments.

[0020] See also Figure 1 As shown, the 300Nm provided in this embodiment 3 / h mobile electrolysis hydrogen production control system structure, including hydrogen production container A, purification container B, power supply container C, cooling and heat exchange equipment D and EDI ultrapure water equipment E;

[0021] The hydrogen production container A is provided with a main CPU controller 1, a first IO device 3, a manageable layer switch 4 and a first conversion gateway 5, and the main CPU controller 1, the first IO device 3, the manageable layer switch 4 and the first conversion gateway 5 are communicatively connected in sequence; the purification container B is provided with a backup CPU controller 2, a second IO device 7 and a second conversion gateway 6, and the backup CPU controller 2, the second IO device 7 and the second conversion gateway 6 are communicatively connected in sequence; the main CPU controller 1 is communicatively connected to the backup CPU controller 2, and the first conversion gateway 5 is communicatively connected to the second conversion gateway 6, so that the devices in the hydrogen production container A and the purification container B are combined to form a ring network redundancy system supporting the S2 mode.

[0022] Among them, the main CPU controller 1 is located in the hydrogen production container A, and the backup CPU controller 2 is located in the purification container B. When the main CPU controller 1 fails, the backup CPU controller 2 will take over the system control. The first IO device 3 of the hydrogen production container and the second IO device 7 of the purification container are respectively the data input and output modules inside their respective containers, which are used to complete signal acquisition and output execution actions. The manageable layer switch 4, the first conversion gateway 5 of the hydrogen production container, and the second conversion gateway 6 of the purification container are combined with the main CPU controller 1, the backup CPU controller 2, the first IO device 3 and the second IO device 7 through the redundant media protocol to form a redundant ring network; all devices in the ring network must support the S2 mode, that is, each device can establish a communication relationship with two devices, and during normal operation, it is only in the main connection state of data exchange with one device, and in the backup connection state with another device; when the main connection fails, the control system switches to the backup state, and data exchange is carried out through the backup connection. For example, the main CPU controller 1 establishes a communication relationship with the IO device 3 and the backup CPU controller 2 in the hydrogen production container. During normal operation, the main CPU controller is in a connected state with the first IO device 3 of the hydrogen production container. When the connection fails, the system switches to the backup state, and the main CPU controller 1 establishes a backup connection with the backup CPU controller 2. This mode can ensure that when a connection in the ring network fails, other devices in the ring network can communicate normally and keep the system stable.

[0023] Normally, the electrolysis hydrogen production control system needs to be equipped with a display operation panel 9 and a wireless communication device 8 for monitoring and controlling the internal operating status of the equipment and remote data transmission. The two devices need to be interconnected with the controller in real time through the system IP. Therefore, the display operation panel 9 and the wireless communication device 8 are connected to the manageable level switch 4 through industrial Ethernet to achieve control communication with other devices in the ring network.

[0024] The hydrogen production container is also provided with a single communication interface device 11 that does not support the S2 mode, which is generally a frequency converter. This type of device has only one communication interface and cannot be connected to the ring network. The single communication interface device 11 is connected to the first switch 10 through the industrial Ethernet, and the data conversion is completed through the conversion gateway 5 in the hydrogen production container, and the signal is connected to the ring network system; in addition, there is no limit on the number of single communication interface devices 11.

[0025] The power container C is provided with a first inverter 13 and a rectifier power controller 14, which are connected to the second switch 12 through industrial Ethernet, and then connected to the second conversion gateway 6 located in the purification container B, and the signal is connected to the ring network system. This connection method enables the purification container B and the power container C to complete the monitoring and control of each device and subsystem in the power container C through only one network cable, effectively reducing the number of hard wiring and reducing the occurrence of data misaccess. In addition, there is no limit on the number of devices and subsystems in the power container C.

[0026] In addition, the mobile hydrogen production system also includes a cooling and heat exchange device D and an EDI ultrapure water device E, wherein the cooling and heat exchange device has a water pump inverter 16 and a heat exchanger controller 15, and the EDI ultrapure water device E has a device controller 17, which are respectively connected to the first switch 10 in the hydrogen production container A, and the data conversion is completed through the first conversion gateway 5 of the hydrogen production container, and the signal is connected to the ring network system. In addition, the number of devices and subsystems in the cooling and heat exchange device D and the EDI ultrapure water device E is not limited.

[0027] The mobile hydrogen production control system structure proposed by the utility model can complete the operation of all equipment and subsystems including hydrogen production containers, purification containers, power supply containers, cooling and heat exchange equipment, and EDI ultrapure water equipment. The established ring network redundant system enables two processors CPU to process the same project data and the same user program in parallel, and synchronize through two redundant connections. If one CPU fails, the other CPU will take over its control, which can effectively prevent data loss and avoid downtime. Through the cooperation of the conversion gateway and switches of different models, the communication and control of various devices that do not have S2 mode subsystems can be completed.

[0028] The embodiments described above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made based on the shape and principle of the present invention should be included in the protection scope of the present invention.
