Embodiment Construction
[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0041] In one embodiment, such as figure 1 As shown, a flow control method is provided, including steps:
[0042] S110, acquire the first flow data output by the flow sensor, and obtain the error of the first average flow according to the first flow data; wherein, the flow sensor is used to detect the medium flow of the pipe section to be measured;
[0043] Wherein, the flow sensor can be any sensor used to detect liquid flow and flow velocity in the art. The first flow data may be data collected during a certain preset time period. The error can be an error ratio or an...

The invention relates to a flow control method, device and equipment and a storage medium. The flow control method comprises the following steps: acquiring first flow data output by a flow sensor, and obtaining an error of first average flow according to the first flow data, wherein the flow sensor is used for detecting the medium flow of a to-be-detected pipe section; under the condition that the error of the first average flow does not fall into the first preset range, controlling a valve in the to-be-detected pipe section to act according to the first average flow; under the condition that the valve starts to act, obtaining second flow data output by the flow sensor, and obtaining the current instantaneous flow according to the second flow data; and if the current instantaneous flow is smaller than the threshold value, controlling the valve to stop acting till the current instantaneous flow is larger than the threshold value. According to the flow control method, the situation that the valve needs to act quickly when the flow of the to-be-measured pipeline changes quickly or in a short time is avoided, and meanwhile, the valve is controlled to stop acting according to the current instantaneous flow so as to avoid useless valve action.
Description
technical field [0001] The present application relates to the technical field of pipeline flow control, in particular to a flow control method, device, equipment and storage medium. Background technique [0002] A flow sensor is a detection instrument used to detect the flow parameters of liquids, gases and other media and convert them into other forms of signals for output. It is widely used in the field of automatic control. In the process of pipeline flow control, the opening and closing angle of the valve is often controlled according to the data transmitted by the flow sensor. [0003] During the implementation process, the inventor found at least the following problems in the traditional technology: the problem of low service life of the valve in the traditional flow control technology. Contents of the invention [0004] Based on this, it is necessary to address the above technical problems and provide a flow control method, device, equipment and storage medium that...
