Embodiment Construction
[0045] When detecting gas pressure, the prior art mainly uses mechanical equipment for detection. In one of the solutions, a mechanical chamber is used to detect the gas pressure. The principle is to use the movement of the scale on the mechanical device to reflect the current pressure intensity of the gas being detected. Specifically, the mechanical equipment is provided with a movable scale and a corresponding scale scale, and the scale scale corresponds to a certain gas pressure intensity. When the mechanical equipment detects the gas pressure intensity, the scale moves to the corresponding position and reads The scale scale at this position can obtain the current pressure intensity value of the gas being detected.
[0046] In another solution, a mechanical film is used to detect the gas pressure. The principle is to use the change of capacitance or resistance caused by the movement of the moving contact piece on the mechanical device to reflect the current pressure intensi...

The embodiment of the invention discloses a gas pressure detection method and device. The method includes the following steps that an electric signal generated by a capacitive gas pressure sensing device can be obtained, and the electric signal characterizes the gas pressure intensity of a detected gas, then a first voltage value can be determined according to the electric signal, and the first voltage value is a peak value of the electric signal; and then according to the correspondence relationship between a pre-established voltage value and the gas pressure intensity, and a gas pressure intensity value corresponding to the first voltage value, namely, the gas pressure intensity value of the detected gas, can be determined. Therefore, the capacitive gas pressure sensing device is usuallysmall in size, and the capacitive gas pressure sensing device can be integrated into terminal equipment which users often use and can be carried conveniently by the users, so that the use experienceof the users can be improved.
Description
technical field [0001] The present application relates to the field of gas pressure detection, in particular to a method and device for gas pressure detection. Background technique [0002] In real life, there may be a need to detect the strength of the gas pressure in a certain environment. For example, in some scenarios, it may be necessary to detect whether the natural gas pressure exceeds the standard, so as to prevent the natural gas pressure from exceeding the standard and cause safety hazards. [0003] In the existing solutions for detecting gas pressure, in order to ensure the accuracy of gas pressure detection as much as possible, most of them use mechanical equipment to detect gas pressure, but usually, the volume of mechanical equipment is large, and it is not easy for users to carry it. Contents of the invention [0004] In view of this, the embodiments of the present application provide a gas pressure detection method and device to solve the technical problem ...
