[0024] This invention provides a pipeline valve chamber monitoring, alarm, and shut-off system, which has the following advantages compared with the prior art:

[0025] This invention comprises a pressure acquisition module, a human-machine interface module, several calculation modules, and several output modules. The pressure acquisition module first acquires the pressure in the valve chamber of the pipeline. Then, the user can select a target alarm condition through the human-machine interface module. Next, the calculation modules calculate the pressure drop rate of the valve chamber based on the pressure, and determine whether the pressure drop rate meets the target alarm condition. Finally, when the pressure drop rate meets the target alarm condition, the output modules output a valve-closing command. In this way, on the one hand, the user can select a target alarm condition, meeting user needs and improving the user experience; on the other hand, the selected target alarm condition can reduce false alarms and accidental shutdowns, improving pipeline safety and production continuity. Simultaneously, the system incorporates redundant configurations, improving system reliability.

[0026] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description, claims and drawings. Attached Figure Description

[0027] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with the embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0028] Figure 1 shows a schematic diagram of a pipeline valve chamber monitoring alarm and shutdown system according to an embodiment of the present invention.

[0029] In the accompanying drawings, the same parts use the same reference numerals. Also, the drawings are not drawn to scale.

[0030] The meanings of the reference numerals in the attached figures are as follows:

[0031] 10 – Pressure Acquisition Module; 20 – Human-Machine Interface Module; 30 – Several Calculation Modules

[0032] 40 – Several output modules; 50 – Pipeline; 60 – Valve chamber

[0033] 70 – Shut-off valve; 80 – Pressure testing instrument Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] The existing system does not employ redundant configurations, resulting in poor reliability. On one hand, module failures in the system can lead to system malfunctions, causing the system to issue incorrect commands and resulting in accidental shutdowns and economic losses. On the other hand, if a pipeline ruptures and a module in the system fails to output valve-closing commands, it can cause pipeline leaks, resulting in economic losses or even serious consequences such as fires and explosions.

[0036] The prior art (CN114607945B) mentions a pipe rupture detection system and method, including: a pressure detection module, a data validity judgment module, a pressure drop rate determination module, a decision module, and an execution module; effectively avoiding system erroneous startup, thereby improving the accuracy of pipe rupture detection, improving the reliability of the pipe rupture detection system, and ensuring pipeline safety. However, this prior art does not disclose a human-machine interface module, and neither the calculation module nor the output module uses redundant settings.

[0037] To address the aforementioned deficiencies in the prior art, the present invention provides a pipeline valve chamber monitoring, alarm, and shutdown system. Figure 1 shows a schematic diagram of a pipeline valve chamber monitoring, alarm, and shutdown system according to an embodiment of the present invention. The system includes: a pressure acquisition module 10, a human-machine interface module 20, several calculation modules 30, and several output modules 40.

[0038] The pressure acquisition module 10 is connected to the valve chamber 60 in the pipeline 50 and is used to acquire the pressure of the valve chamber 60;

[0039] Human-machine interface module 20 is used to select target alarm conditions based on the number of pressure acquisition modules 10;

[0040] Several calculation modules 30 are connected to the pressure acquisition module 10 and the human-machine interface module 20, and are used to calculate the pressure drop rate of the valve chamber 60 based on the pressure; and determine whether the pressure drop rate meets the target alarm conditions.

[0041] Several output modules 40 are connected to several calculation modules 30 to output valve closing commands when the pressure drop rate meets the target alarm conditions.

[0042] For example, there may be one valve chamber 60 in pipeline 50; or there may be multiple valve chambers 60. As shown in Figure 1, the number of pressure acquisition modules 10 may include multiple modules; the pressure acquisition module 10 may be connected to the pressure detection instrument 80 inside the valve chamber 60 to upload the pressure of the valve chamber 60 detected by the pressure detection instrument 80 to the pressure acquisition module 10. Pipeline 50 may be a long-distance pipeline or a collection and transportation pipeline.

[0043] This invention comprises a pressure acquisition module, a human-machine interface module, several calculation modules, and several output modules. The pressure acquisition module first acquires the pressure in the valve chamber of the pipeline. Then, the user can select a target alarm condition through the human-machine interface module. Next, the calculation modules calculate the pressure drop rate of the valve chamber based on the pressure, and determine whether the pressure drop rate meets the target alarm condition. Finally, when the pressure drop rate meets the target alarm condition, the output modules output a valve-closing command. In this way, on the one hand, the user can select a target alarm condition, meeting user needs and improving the user experience; on the other hand, the selected target alarm condition can reduce false alarms and accidental shutdowns, improving pipeline safety and production continuity. Simultaneously, the system incorporates redundant configurations, improving system reliability.

[0044] In one possible embodiment, the pressure acquisition module 10 includes a first pressure acquisition module and a second pressure acquisition module that are redundantly connected to each other.

[0045] For example, one of the pressure acquisition modules 10 can be a first pressure acquisition module, and the other of the pressure acquisition modules 10 can be a second pressure acquisition module. As shown in Figure 1, the plurality of pressure modules may also include a third pressure acquisition module, which is redundantly connected to the first pressure acquisition module and the second pressure acquisition module.

[0046] In this way, the pressure acquisition module 10 is composed of a first pressure acquisition module and a second pressure acquisition module that are redundantly connected to each other, which avoids the situation where the system fails when any pressure acquisition module fails, reduces the occurrence of accidental shutdown, and improves the reliability of the system.

[0047] In one possible embodiment, the number of pressure acquisition modules 10 includes two;

[0048] The target alarm conditions include: one of the voltage drop rates is greater than the preset alarm value;

[0049] The target alarm conditions also include: the voltage drop rate is greater than the preset alarm value.

[0050] When there are two valve chambers 60, the user can select the target alarm condition as: the pressure drop rate of one of the two valve chambers 60 is greater than the preset alarm value, thus improving the safety of the system.

[0051] Users can also select the target alarm condition as: the pressure drop rate of both valve chambers 60 is greater than the preset alarm value, thus improving the production continuity of the system.

[0052] In this way, users can select alarm conditions, which meets their needs and improves their user experience.

[0053] In one possible embodiment, the number of pressure acquisition modules 10 includes three;

[0054] The target alarm conditions include: one of the voltage drop rates is greater than the preset alarm value;

[0055] The target alarm conditions also include: both of the voltage drop rates are greater than the preset alarm value;

[0056] The target alarm conditions also include: the voltage drop rate is greater than the preset alarm value.

[0057] When there are three valve chambers 60, the user can select the target alarm condition as follows: the pressure drop rate of one of the three valve chambers 60 is greater than the preset alarm value, thus improving the safety of the system.

[0058] Users can also select the target alarm condition as follows: the pressure drop rate of two of the three valve chambers 60 is greater than the preset alarm value, thus balancing safety and production continuity.

[0059] Users can also select the target alarm condition as: the pressure drop rate of all three valve chambers 60 is greater than the preset alarm value, thus improving the production continuity of the system.

[0060] In this way, users can select alarm conditions, which meets their needs and improves their user experience.

[0061] For example, the number of pressure acquisition modules 10 can be other numbers, and the corresponding target alarm conditions can also be multiple, which will not be elaborated here.

[0062] In one possible embodiment, the plurality of computing modules 30 includes: a first computing module and a second computing module that are redundantly connected to each other.

[0063] As shown in Figure 1, one of the several calculation modules 30 can be a first calculation module, and the other of the several calculation modules 30 can be a second calculation module.

[0064] In this way, the computing modules 30 are composed of a first computing module and a second computing module that are redundantly connected to each other, which reduces the occurrence of system failure when any computing module fails, reduces the occurrence of accidental shutdown, and improves the reliability of the system.

[0065] In one possible embodiment, the plurality of output modules 40 includes: a first output module and a second output module that are redundantly connected to each other.

[0066] As shown in Figure 1, one of the several output modules 40 can be the first output module, and the other of the several output modules 40 can be the second output module.

[0067] In this way, the output modules 40 are composed of the first output module and the second output module, which avoids the situation where the valve closing command cannot be accurately output when any output module fails, reduces the leakage of the pipeline 50, improves the safety of the pipeline 50, and reduces economic losses, personal injury and environmental pollution.

[0068] In one possible embodiment, the system further includes a shut-off valve 70 disposed within a valve chamber 60 and connected to a plurality of output modules 40 for closing the pipeline 50 in response to receiving a valve closing command.

[0069] Each valve chamber 60 may contain a shut-off valve 70.

[0070] In one possible embodiment, the system further includes a solenoid valve connected to the shut-off valve 70 for controlling the opening and closing of the shut-off valve 70.

[0071] The gas or liquid path of the shut-off valve 70 is usually controlled by a solenoid valve.

[0072] Considering that a failure of the solenoid valve may cause the shut-off valve 70 to fail to open or close, in order to improve the reliability of the pipeline 50, redundant solenoid valves can be configured, that is, multiple solenoid valves may be included.

[0073] Thus, the system also includes a solenoid valve, which controls the opening and closing of the shut-off valve 70, thereby improving the reliability of the system.

[0074] In summary, this invention provides a pipeline valve chamber monitoring, alarm, and shut-off system, which has the following advantages compared with the prior art:

[0075] This invention comprises a pressure acquisition module, a human-machine interface module, several calculation modules, and several output modules. The pressure acquisition module first acquires the pressure in the valve chamber of the pipeline. Then, the user can select a target alarm condition through the human-machine interface module. Next, the calculation modules calculate the pressure drop rate of the valve chamber based on the pressure, and determine whether the pressure drop rate meets the target alarm condition. Finally, when the pressure drop rate meets the target alarm condition, the output modules output a valve-closing command. In this way, on the one hand, the user can select a target alarm condition, meeting user needs and improving the user experience; on the other hand, the selected target alarm condition can reduce false alarms and accidental shutdowns, improving pipeline safety and production continuity. Simultaneously, the system incorporates redundant configurations, improving system reliability.
