[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the flow gas pressure control device of the present invention comprises: a flow gas pressure control system 1 and a flow guide device 2, wherein the flow gas pressure control system 1 comprises a pressure sensing unit, an operation unit, and a control unit; the operation unit comprises a digital signal conversion unit, an instruction unit, and an information storage unit; the pressure sensing unit is connected to the operation unit, and the operation unit is connected to the control unit;

[0024] The pressure sensing unit is used to monitor and calculate the gas pressure value in the space. If the gas pressure value reaches the set index coefficient, the gas pressure value is sent to the calculation unit;

[0025] The computing unit is used to receive the gas pressure value, the digital signal conversion unit is used to convert the gas pressure value into a digital signal and send it to the instruction unit, the instruction unit is used to convert the digital signal into a control instruction and send it to the control unit; the information storage unit is used to store real-time or historical data;

[0026] The control unit is used to execute a control function after receiving a control instruction.

[0027] The control functions include on / off switches, intelligent management, human-computer interaction, etc.

[0028] The index coefficient is set according to the use environment.

[0029] The flowing gas pressure control device further comprises a battery for supplying power to the flowing gas pressure control system.

[0030] The flow gas pressure control device can be combined with a vehicle air conditioner, a household air conditioner, a fan or a ventilation duct.

[0031] like Figure 2 As shown, the pressure control device can be placed at the air outlet 3 of any device or at a place where gas flow occurs in the space. Through the change of gas flow, the pressure control device can sense the pressure difference, wherein the operation unit is composed of an integrated circuit. When the change meets the specific application requirements, the operation unit will issue relevant instructions to the control unit through environmental operating parameters or manual operation, and the control unit will perform corresponding control functions on the device that generates flowing gas according to the relevant instructions.

[0032] like Figure 3 As shown, Figure 3 The middle dotted line is the pressure curve after data conversion and pressure control. Through data conversion processing, the information can be better fitted and preliminary data analysis can be performed. Figure 3 The solid line in the middle is the change curve of the pressure direct value. The curve has offset or nonlinear values, so the error is large.

[0033] like Figure 4 As shown, the pressure control system is combined with a flow guide device to deliver the gas flowing in the space to the pressure sensing unit more stably. The flow guide device can be arbitrarily adapted and deformed to meet the needs of various environments.

[0034] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the essence and scope of the present invention. Therefore, all equivalent technical solutions also belong to the protection scope of the present invention.
