In the related art, the water hammer lead protection function is generally implemented by a programmable logic controller pre-configured in a pipeline. However, under the condition that a programmable logic controller is not configured in advance in the pipeline construction process, the water hammer advanced protection function of the pipeline cannot be realized, so that the deployment of the industrial control system of the long oil and gas pipeline of the newly-transferred pipeline is difficult.
