[0002] Compressed air is widely used in various industrial equipment, but currently, workshop management of compressed air mainly relies on manual inspections, lacking real-time and effective monitoring and management methods. Due to the lack of precise flow monitoring methods, it is difficult to grasp the flow changes in each compressed air pipeline in real time, which may lead to missed equipment malfunctions or flow anomalies. Furthermore, manual inspections are inefficient: for the current workshop situation, manual inspections are not only time-consuming but also lack real-time response capabilities, easily overlooking equipment malfunctions.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products or devices.

[0020] Figure 1 A schematic diagram of a compressed air pipeline fault monitoring system provided in this embodiment of the present invention is shown below. Figure 1 As shown, the compressed air pipeline fault monitoring system includes: a flow detection sensor 10, a controller 20, a control valve 30, and a remote terminal device 40; the flow detection sensor 10 is installed in the compressed air pipeline; the flow detection sensor 10 is electrically connected to the controller 20 to detect the current compressed air flow rate in the compressed air pipeline and send the current compressed air flow rate to the controller 20; the control valve 30 is installed in the compressed air pipeline; the controller 20 is electrically connected to the control valve 30 to control the control valve 30 to open or close; the remote terminal device 40 is communicatively connected to the controller 20 to determine whether the compressed air pipeline and the control valve 30 are faulty based on the output information of the controller 20.

[0021] Specifically, when the gas in the cylinder flows to the equipment through the compressed air pipeline, under normal circumstances, the real-time flow rate of compressed air in the pipeline always meets the preset compressed air flow rate range. Furthermore, when the equipment is operating normally, the control valve 30 is appropriately open to ensure the normal flow of compressed air within the pipeline. When the equipment stops working, the control valve 30 can be closed to stop the flow of compressed air in the pipeline, thereby reducing energy consumption. If the real-time flow rate of compressed air in the pipeline exceeds the preset range during normal operation, it may indicate a fault in the compressed air pipeline or the control valve. Operators need to promptly inspect and repair the compressed air pipeline and control valve to ensure the normal operation of the equipment.

[0022] Specifically, the flow detection sensor 10 is installed in the compressed air pipeline. When gas flows through the flow detection sensor 10, the change in flow rate affects the thermal balance of the flow detection sensor 10, thereby changing the temperature difference, which is then converted into an electrical signal output. That is, the flow detection sensor 10 can detect the compressed air flow rate in the compressed air pipeline in real time. The flow detection sensor 10 is electrically connected to the controller 20, so the flow detection sensor 10 can send the detected current compressed air flow rate to the controller 20.

[0023] Specifically, the control valve 30 is installed in the compressed air pipeline, and the controller 20 is electrically connected to the control valve 30 to control the opening or closing of the control valve 30. Thus, when the control valve is in the open state, compressed air in the cylinder can pass through the compressed air pipeline to meet the equipment's application requirements; when the control valve is in the closed state, compressed air in the cylinder cannot pass through the compressed air pipeline.

[0024] Specifically, the remote terminal device 40 is communicatively connected to the controller 20 and is used to determine whether the compressed air pipeline and control valve 30 are faulty based on the output information of the controller 20. The controller 20 can determine whether the compressed air pipeline and control valve 30 are faulty based on the current compressed air flow rate and the preset compressed air flow rate range, and send the output information to the remote terminal device 40 so that the operator can check it on the remote terminal device. When the current compressed air flow rate does not meet the preset compressed air flow rate range, it indicates that there is an abnormality in the compressed air pipeline or control valve, and the operator can promptly inspect and repair the compressed air pipeline and control valve 30. Alternatively, the controller 20 can send the current compressed air flow rate to the remote terminal device 40, and the remote terminal device 40 can then determine whether the compressed air pipeline and control valve are faulty based on the current compressed air flow rate and the preset compressed air flow rate range, thereby improving the reliability of equipment operation.

[0025] For example, the controller 20 and the remote terminal device 40 can communicate via Ethernet, so that the remote terminal device 40 can monitor the current compressed air flow in the compressed air pipeline and the working status of the control valve in real time, thereby realizing remote real-time monitoring.

[0026] For example, the wireless terminal device can be an electronic device with display and communication functions, such as a mobile phone or a computer, or a wireless gateway device. This utility model embodiment does not specifically limit the type of wireless terminal device.

[0027] The compressed air pipeline fault monitoring system provided in this embodiment of the invention uses a flow detection sensor installed in the compressed air pipeline. This sensor can detect the current compressed air flow rate in the pipeline in real time and send the data to the controller. In other words, it uses a digital flow detection sensor to monitor the flow rate in the compressed air pipeline in real time, enabling refined management. A control valve is installed in the compressed air pipeline; the controller is electrically connected to the control valve, allowing the controller to control the valve's operating status. A remote terminal device is communicatively connected to the controller and uses the controller's output information to determine whether the compressed air pipeline and control valve are faulty. This allows operators to promptly inspect the compressed air pipeline and control valve when the current compressed air flow rate does not meet the preset range, improving equipment operational reliability.

[0028] Optional, continue to refer to Figure 1 The controller 20 is used to determine whether the compressed air pipeline and control valve 30 are faulty based on the current compressed air flow rate, and sends the fault result information to the remote terminal device 40; the output information includes the fault result information; or, the controller 20 is used to transmit the current compressed air flow rate to the remote terminal device 40, and the remote terminal device 40 is used to determine whether the compressed air pipeline and control valve 30 are faulty based on the current compressed air flow rate; the output information includes the current compressed air flow rate.

[0029] As a feasible implementation method, the flow detection sensor 10 sends the detected current compressed air flow rate to the controller 20. The controller 20 determines whether the compressed air pipeline and control valve are faulty based on the current compressed air flow rate and the preset compressed air flow rate range, and sends the fault result information to the remote terminal device 40 for display. In this way, the operator can promptly understand whether the compressed air pipeline and control valve 30 are faulty by viewing the fault result information, and promptly repair the compressed air pipeline and control valve 30 when a fault occurs, so as to ensure the normal operation of the equipment.

[0030] As another feasible implementation, the flow detection sensor 10 sends the detected current compressed air flow rate to the controller 20, and the controller 20 sends the current compressed air flow rate to the remote terminal device 40. The remote terminal device 40 then determines whether the compressed air pipeline and control valve are faulty based on the current compressed air flow rate and the preset compressed air flow rate range, so that the remote terminal device 40 can display the result. In this way, the operator can promptly understand whether the compressed air pipeline and control valve are faulty by viewing the fault result information, and promptly repair the compressed air pipeline and control valve when a fault occurs, so as to ensure the normal operation of the equipment.

[0031] Optional, continue to refer to Figure 1 The compressed air pipeline fault monitoring system also includes: an alarm 50; the alarm 50 is electrically connected to the controller 20.

[0032] Specifically, the alarm 50 can issue an alarm signal when the controller 20 determines that the current compressed air flow does not meet the preset compressed air flow range, so as to warn the operator to inspect the compressed air pipeline and control valve in time.

[0033] Optional, continue to refer to Figure 1 Alarm 50 includes an audible alarm and / or alarm 50 includes a light alarm.

[0034] As one possible implementation, the alarm 50 includes an audible alarm, which will sound an alarm to alert the operator when the current compressed air flow does not meet the preset compressed air flow range.

[0035] As another feasible implementation, the alarm 50 includes a light alarm, which emits a light warning when the current compressed air flow does not meet the preset compressed air flow range, to alert the operator.

[0036] As another feasible implementation, the alarm 50 includes a light alarm and a light alarm, so that when the current compressed air flow does not meet the preset compressed air flow range, the alarm will issue an audible and visual warning to further alert the operator.

[0037] Optional, continue to refer to Figure 1 The flow detection sensor 10 includes a heating unit 101 and a temperature sensing unit 102; the heating unit 101 and the temperature sensing unit 102 are arranged sequentially along the flow direction of compressed air in the compressed air pipeline.

[0038] Specifically, the flow detection sensor 10 detects flow based on the principle of thermal sensing, that is, it uses the difference between the heating unit 101 and the temperature sensing unit 102 to measure the flow rate. When gas flows through the flow detection sensor 10, the change in flow rate will affect the thermal balance of the flow detection sensor 10, thereby changing the temperature difference, and then the thermal signal will be converted into an electrical signal output to realize flow detection.

[0039] Specifically, the heating unit 101 and the temperature sensing unit 102 are arranged sequentially along the flow direction of compressed air in the compressed air pipeline. That is, the compressed air flowing into the compressed air pipeline is first heated by the heating unit 101, and then the temperature is detected by the temperature sensing unit 102. The temperature sensing unit 102 is used to detect the temperature change after the compressed air carries away the heat, and forms a temperature difference signal with the heating temperature of the heating unit 101 to output the current compressed air flow rate.

[0040] Optional, continue to refer to Figure 1 The temperature sensing unit 102 includes a thermistor or a thermocouple.

[0041] As a feasible implementation, the temperature sensing unit 102 includes a thermistor, which can convert the temperature change of compressed air into a resistance signal, and then convert it into a temperature reading through a circuit. Because the thermistor responds quickly to temperature changes and has high accuracy, it is suitable for monitoring the real-time temperature at the outlet of the heating unit 101, providing feedback signals to the control system, and realizing closed-loop temperature regulation.

[0042] As another feasible implementation, the temperature sensing unit 102 includes a thermocouple. Since the thermocouple has strong high temperature resistance, it is beneficial to ensure the stability and reliability of the flow detection sensor 10.

[0043] Optional, continue to refer to Figure 1 The controller 20 includes a programmable logic controller.

[0044] Specifically, programmable logic controllers (PLCs) possess high reliability and strong anti-interference capabilities, ensuring the stability and reliability of compressed air pipeline fault monitoring systems. Furthermore, PLCs feature millisecond-level scan cycles and precise input and output port responses, enabling high-speed real-time control.

[0045] Specifically, Figure 2 This invention provides a schematic diagram illustrating the electrical connections between the controller, the flow detection sensor, and the control valve, as shown in the embodiment of the present invention. Figure 2As shown, the flow detection sensor 10 includes a first flow detection sensor 11 installed in the compressed air pipeline of the winding and sealing machine, a second flow detection sensor 12 installed in the compressed air pipeline of the packaging main machine, and a third flow detection sensor 13 installed in the compressed air pipeline of the packaging auxiliary machine. The control valve 30 includes a first control valve 31 installed in the compressed air pipeline of the winding and sealing machine, a second control valve 32 installed in the compressed air pipeline of the packaging main machine, and a third control valve 33 installed in the compressed air pipeline of the packaging auxiliary machine. The first flow detection sensor 11, the second flow detection sensor 12, and the third flow detection sensor 13 are electrically connected to different input ports of the same programmable logic controller (PLC), so that the controller 20 can receive the compressed air flow rate in the corresponding compressed air pipeline detected by each flow detection sensor. The first control valve 31, the second control valve 32, and the third control valve 33 are electrically connected to different output ports of the same PLC, so that the controller 20 can control the operating state of each control valve, thereby controlling the flow of compressed air in the corresponding compressed air pipeline.

[0046] It should be noted that, to prevent prolonged ineffective operation of the compressed air system, the system can be timed to shut down. For example, when the equipment is in a non-production state (such as during night shifts or holidays) or the programmable logic controller detects that the equipment downtime has reached a set time (such as during extended maintenance), the control valve of the corresponding pipeline will be automatically closed to avoid energy waste and equipment damage. In other words, the controller 20 can automatically determine and close the control valve based on time strategies and operating status, preventing compressed air loss during prolonged equipment downtime or unattended night shifts, thus improving the system's energy efficiency and safety reliability. Furthermore, it can reduce the frequency of manual inspections and interventions, improving workshop management efficiency and automation levels.

[0047] It should be noted that the relevant timing parameters and automatic shutdown logic can be configured and adjusted on remote terminal devices.

[0048] Optional, continue to refer to Figure 1 The alarm 50 and the controller 20 are electrically connected via a relay 60.

[0049] Specifically, by setting a relay 60 between the alarm 50 and the controller 20, electrical isolation between the alarm 50 and the controller 20 is achieved through the relay 60, that is, high and low pressure isolation is achieved, thereby improving the anti-interference capability of the compressed air pipeline fault monitoring system.

[0050] Optional, continue to refer to Figure 1 The control valve 30 includes a solenoid valve, in which electromagnetic force can be used to drive the valve core of the solenoid valve to control the flow of fluid, thereby achieving precise control of the fluid in the compressed air pipeline.

[0051] It should be noted that the model of the solenoid valve can be selected based on factors such as the working pressure and flow rate of the compressed air pipeline and the response time of the valve.

[0052] In summary, the compressed air pipeline fault monitoring system provided by this utility model embodiment, by installing flow detection sensors in the compressed air pipeline, enables real-time detection of the flow rate within the pipeline, achieving refined management. This allows operators to promptly monitor the compressed air flow rate and, in the event of a fault, promptly inspect the compressed air pipeline and control valves, improving equipment operational reliability. Multiple protection mechanisms, including fault alarms and automatic shutdown, ensure the safe operation of equipment and systems, enhancing the overall automation and intelligent management capabilities of the factory.
