[0015] Preferably, the processing center is further provided with an external communication unit, which synchronizes the analysis results, detection data and visual display information to an external management platform.

[0016] Preferably, the external communication unit is connected to an alarm terminal.

[0017] On the other hand, the present invention discloses a pressure testing method for fire protection pipeline water testing, comprising the following steps: S1: establishing a pressure reference and initializing a pressure detection module and a water flow detection module; S2: after opening the water test valve, collecting pressure data and pipeline vibration frequency in real time; S3: determining the water status based on the monitoring data in S2; S4: outputting the test results; S5: regularly and automatically calibrating the pressure detection module and the water flow detection module.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] Combined with attachment Figure 1-2As shown, a pressure testing system for water testing of fire protection pipelines includes a pressure detection module, a water flow detection module, a nozzle positioning module, a data acquisition module and a processing center; the pressure detection module is used to collect pipeline pressure data in real time, the water flow detection module obtains the fluctuation frequency of the space in the fire protection pipeline, and the nozzle positioning module is used to locate the nozzle position of the collection pipeline; the data acquisition module collects the detection data of the pressure detection module and the water flow detection module, and outputs the analysis results through the processing center. The processing center associates the analysis results with the positioning information of the nozzle positioning module to visualize the data of different fire protection pipelines.

[0024] The present invention, when implemented, includes the following steps: S1: establishing a pressure reference and initializing a pressure detection module and a water flow detection module; S2: after opening a water test valve, collecting pressure data and pipeline vibration frequency in real time; S3: determining the water status based on the monitoring data in S2; S4: outputting the test results; and S5: regularly and automatically calibrating the pressure detection module and the water flow detection module.

[0025] The pressure detection module includes multiple high-precision pressure sensors, which are arranged at key nodes of the fire protection pipeline. The water flow detection module includes one or a combination of acoustic sensors and vibration sensors, and is installed before the water outlet valve of the indoor fire hydrant.

[0026] The water flow detection module captures the frequency signal generated by the water flow fluctuation in the pipeline, and converts the frequency signal into an electrical signal and transmits it to the data acquisition module.

[0027] The sprinkler positioning module includes pipeline positioning units arranged in each branch of the fire protection pipeline. The pipeline positioning units located in the same branch are associated with the water flow detection module information, and the data acquisition module includes a data preprocessing unit and a calibration unit. The data preprocessing unit filters and amplifies the collected signal; the calibration unit regularly performs zero point calibration and range calibration on the pressure detection module and the water flow detection module.

[0029] In one embodiment:

[0030] Initialize the pressure detection module and water flow detection module, set initial parameters, and establish a pressure baseline to provide a reference for subsequent testing and analysis. After opening the water test valve, the pressure detection module collects pipeline pressure data in real time, and the water flow detection module collects pipeline vibration frequency (i.e., water flow fluctuation frequency). The collected data is transmitted to the data acquisition module, and a pipeline network pressure distribution benchmark model is constructed. Based on the pressure detection data and pipeline vibration frequency, judgments are made. By analyzing the changing trends of pressure data and the characteristics of pipeline vibration frequency, it is determined whether there are abnormal conditions such as leaks and blockages in the pipeline, as well as whether the water flow state is stable. The results of the water state judgment, including information such as pipeline pressure distribution and water flow state, are visualized through the processing center and a test report is output.
