An embodiment of the present invention provides a gas flow control cabinet, as shown in fig. 1, the gas flow control cabinet includes: the main controller (located inside the cabinet body and not marked in the figure), the gas channels (such as 1 and 2 in the figure), and the gas flow collecting devices (such as 3 and 4 in the figure) located on the gas channels, wherein the gas channels are used for transporting gas to the external equipment;
and the main controller is connected with the gas flow acquisition device and is used for carrying out closed-loop control on the gas flow in the gas channel according to the given gas flow and the actual gas flow acquired by the gas flow acquisition device.
For example, the gas channels 1 and 2 in the figure can be, but are not limited to, flowing through natural gas and oxygen, and the gas flow control cabinet can simultaneously have a plurality of gas channels for transmitting different gases according to actual operation requirements. Correspondingly, the gas flow collecting device 3 and the gas flow collecting device 4 on the gas channel are not limited to gas flow collecting equipment adopting any working principle, and can collect gas flow parameters of the internal gas of the gas channel where the gas flow collecting equipment is located. The main controller can be built by adopting a Programmable Logic Controller (PLC).
In a specific embodiment, the gas flow collecting device may be a proportional flow valve, and is configured to transmit the collected analog electrical signal to the main controller;
correspondingly, a pre-trained flow conversion model is arranged in the main controller, and can be used for converting the analog electric signal into actual gas flow flowing through the gas channel and feeding back a gas flow control signal to the proportional flow valve so as to adjust the gas flow in the gas channel through the proportional flow valve and realize closed-loop control.
Specifically, the proportional flow valve may be configured to detect an analog electrical signal in the gas channel (the magnitude of the analog electrical signal is related to the magnitude of the gas flow in the gas channel), and the analog electrical signal is converted by the flow conversion model to obtain the actual gas flow in the gas channel. The flow conversion model in the scheme is obtained by training and learning the relationship between the analog electric signal generated by the proportional flow valve and the actual gas flow in the gas channel in the early stage.
The main controller generates a gas flow control signal according to the difference value between the given gas flow and the actual gas flow collected by the gas flow collecting device, feeds the control signal back to the proportional flow valve, adjusts the valve opening of the proportional flow valve, and further adjusts the gas flow in the gas channel, so that the actual gas flow follows the given gas flow, and closed-loop control is realized.
In an embodiment, the gas flow control cabinet further includes: and the HIMI (high definition multimedia interface) man-machine interaction screen 5 is used for receiving the given gas flow input by an operator and displaying the actual gas flow acquired by the gas flow acquisition device.
