Description

Technical Field

[0001] This application relates to the field of gas extraction technology, and in particular to a gas pumping station monitoring system. Background Technology

[0002] Coal mine gas drainage pumping stations (referred to as gas pumping stations) are the core equipment for coal mine gas control. Used on the surface or underground, they effectively reduce local gas emissions and weaken the energy and impact of gas in outburst accidents. For low-concentration or unusable gas, underground gas pumping stations transport it through pipelines to the gas emission system for dilution and safe discharge. High-concentration gas is also pumped through the station to the next stage for power generation or fuel.

[0003] Because of the long pipelines involved in gas drainage, most current monitoring systems primarily monitor and measure pipeline parameters, environmental parameters, power supply parameters, and water supply parameters in real time. However, the gas pumping station, as the most critical link in the entire process, lacks monitoring and early warning systems for its operation. This could lead to sudden shutdowns or major malfunctions, compromising the reliable and stable operation of the gas drainage pumping station. Summary of the Invention

[0004] The purpose of this application is to provide a gas pumping station monitoring system that can comprehensively monitor the operating status of the gas pumping station and issue timely warnings to ensure the reliable and stable operation of the gas drainage pumping station.

When a risk of failure is determined, the control unit controls the alarm module to issue a warning. When a failure is determined, the control unit controls the gas pump station to stop and simultaneously controls the alarm module to issue an alarm.

[0006] According to the specific embodiments provided in this application, this application has the following technical effects: This application provides a gas pumping station monitoring system. The signal acquisition module monitors the status signals of different parts of the gas pumping station in real time, comprehensively monitoring the operating status of the gas pumping station.

Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0011] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] To address the current lack of comprehensive monitoring in gas drainage pumping stations, which leads to unreliable operation and potential for sudden or major shutdowns, an exemplary embodiment is proposed, such as... Figure 1 As shown, a gas pumping station monitoring system is provided, including: a signal acquisition module, a control unit 15, and an alarm module 17; the signal acquisition module is used to monitor the status signals of different parts in the gas pumping station in real time; the control unit 15 is used to determine whether there is a fault risk or a fault has occurred in the part based on the status signals, and when a fault risk is determined, it controls the alarm module 17 to issue an early warning, and when a fault is determined, it controls the gas pumping station to stop and simultaneously controls the alarm module 17 to issue an alarm.

[0013] The monitoring system described in this application can comprehensively monitor the operating status of gas pumping stations and issue early warnings based on logical operations and monitoring results, thereby preventing major malfunctions and ensuring stable operation of the gas pumping stations.

[0014] As an optional implementation, the signal acquisition module can monitor various components of the pumping station in real time. The signal acquisition module includes: a first temperature sensor 1, a second temperature sensor 2, a third temperature sensor 3, a fourth temperature sensor 4, a fifth temperature sensor 5, a sixth temperature sensor 9, a seventh temperature sensor 10, a first vibration sensor, a second vibration sensor 6, a third vibration sensor 7, a fourth vibration sensor 8, a first pressure sensor 11, a second pressure sensor 12, and a water flow meter 13.

[0015] The first temperature sensor 1 is used to monitor the temperature of the front bearing of the motor in real time; the second temperature sensor 2 is used to monitor the temperature of the three-phase windings of the motor in real time; and the third temperature sensor 3 is used to monitor the temperature of the rear bearing of the motor in real time. Since the higher the output power of the motor during operation, the greater the current and losses, and the higher the temperature, the temperature feedback is used to determine whether the motor is operating under overload conditions. When the temperature exceeds or approaches a warning value, an early warning will be issued, along with a suggested solution. Therefore, the judgment logic in the control unit 15 is as follows: if any one of the front bearing temperature, the three-phase winding temperature, or the rear bearing temperature exceeds a first preset temperature threshold, then the motor is deemed to have a fault risk.

[0016] The fourth temperature sensor 4 is used to monitor the temperature of the front bearing of the vacuum pump in real time; the fifth temperature sensor 5 is used to monitor the surface temperature of the vacuum pump in real time; and the sixth temperature sensor 9 is used to monitor the temperature of the rear bearing of the vacuum pump in real time. The vacuum pump is a direct device for gas extraction. When the lubricating oil is insufficient or deteriorated, or when the cooling system malfunctions, the temperature of the vacuum pump will rise. If this is not detected in time, it may cause the rotor to seize. The monitoring system of this application uses temperature signals to provide feedback on whether the vacuum pump is operating normally. The judgment logic in the control unit 15 is as follows: if any one of the front bearing temperature, the surface temperature of the vacuum pump, or the rear bearing temperature of the vacuum pump is greater than the second preset temperature threshold, then the vacuum pump is determined to have a risk of failure.

[0017] The seventh temperature sensor 10 is used to monitor the lubricating oil temperature in real time. For example, the seventh temperature sensor 10 is magnetically attached and installed on the upper part of the lubricating oil chamber of the vacuum pump to monitor the lubricating oil temperature in real time. Excessively high lubricating oil temperature will lead to a decrease in lubrication effect, ultimately resulting in a decrease in the vacuum level of the vacuum pump. Temperature monitoring can promptly remind users to replace the lubricating oil. The judgment logic in the control unit 15 is as follows: if the lubricating oil temperature is greater than a third preset temperature threshold, it is determined that there is a risk of lubricating oil failure. For example, the third preset temperature threshold is 95℃. When the lubricating oil temperature exceeds the set value of 95℃, the monitoring system will issue an alarm.

[0018] The first vibration sensor, the second vibration sensor 6, the third vibration sensor 7, and the fourth vibration sensor 8 are used to monitor the vibration values ​​of different parts of the vacuum pump in real time. For example, the fourth temperature sensor 4, the fifth temperature sensor 5, the sixth temperature sensor 9, the first vibration sensor, the second vibration sensor 6, the third vibration sensor 7, and the fourth vibration sensor 8 are installed on the vacuum pump to measure the surface temperature and vibration velocity of the vacuum pump, expressing the magnitude of vibration energy through vibration. When the vacuum pump has been used for a long time, or when parts are worn or loosened, the vibration amplitude will increase. If not addressed promptly, this will affect the performance and lifespan of the vacuum pump. The monitoring system of this application uses vibration signals to report the vibration status of the vacuum pump, and will promptly issue an alarm when the vibration exceeds a threshold. The judgment logic in the control unit 15 is as follows: if the vibration value of any part of the vacuum pump exceeds a preset vibration threshold, it is determined that the vacuum pump has a risk of failure. For example, the preset vibration threshold is 8 mm / s. When the vibration velocity exceeds 8 mm / s, the monitoring system will issue a warning. The first vibration sensor and the fifth temperature sensor 5 can be integrated into a single vibration-temperature sensor, installed at the location of the fifth temperature sensor 5.

[0019] There are two pressure sensors (also known as negative pressure sensors), one installed before and one after the orifice plate. The first pressure sensor 11 is used to monitor the pressure value after the orifice plate in real time; the second pressure sensor 12 is used to monitor the pressure value before the orifice plate in real time. The real-time pumping flow rate can be calculated from the pressure difference before and after the orifice plate and the orifice plate coefficient. The formula is: ; in, Indicates the extraction flow rate. Indicates the orifice coefficient. This indicates the cross-sectional area of ​​the perforated plate. This represents the pressure difference between the front and rear sides. This represents the density of the flow rate. The above formula is derived based on the principle of orifice plate flow meters. The extraction flow rate of the gas pumping station can be displayed in real time on the human-machine interface.

[0020] The extraction flow rate can be calculated using the orifice plate and the pressure difference before and after it, which greatly saves the installation space and cost of the flow meter.

[0021] The pressure value after the orifice plate can be used as feedback for the PID control of the controller to achieve constant negative pressure control of the gas pump station.

[0022] The vacuum pump uses a water seal and water cooling, and a water flow sensor (water flow meter 13) is installed at the water inlet. The water flow meter 13 is used to monitor the flow rate of the cooling water at the water inlet in real time. When the water flow rate is too low (indicating that the set value requirement is not met), the control unit 15 will issue a power-off shutdown command.

[0023] As another optional implementation, the signal acquisition module further includes: a methane sensor 14; the methane sensor 14 is used to monitor the methane concentration in the environment where the gas pump station is located in real time; the control unit 15 is used to control the alarm module 17 to issue an early warning when the methane concentration is greater than the alarm concentration threshold; and to control the gas pump station to shut down when the methane concentration is greater than the fault concentration threshold, while controlling the alarm module 17 to issue an alarm; wherein the alarm concentration threshold is less than the fault concentration threshold.

[0024] For example, the alarm concentration threshold is set to 1.0% of the set value, and the fault concentration threshold is set to 1.5% of the set value. When the ambient methane exceeds 1.5% of the set value, the entire gas pumping station will issue a power-off command through the control unit 15. When it exceeds 1.0% of the set value, an early warning will be issued.

[0025] As an optional implementation, the gas pump station monitoring system also includes: a speed control module 16; the speed control module 16 is connected to the control unit 15 and the motor in the gas pump station respectively; the execution module in the gas pump station includes a motor and a vacuum pump, and the motor drives the vacuum pump through the speed control module 16 to realize gas extraction.

[0026] The control unit 15 has two control modes: manual and automatic, to control the operation of the pump station. In manual mode, the control unit 15 outputs a manually set frequency to the speed control module 16, which adjusts the motor speed according to the manually set frequency. In automatic mode, the control unit 15 performs PID calculations based on the pressure value after the orifice plate to obtain the operating frequency, and outputs the operating frequency to the speed control module 16. The speed control module 16 adjusts the motor speed according to the operating frequency to achieve constant negative pressure extraction. The control unit 15 also stops the gas pump station by controlling the speed control module 16 to shut down when a fault is detected.

[0027] The speed control module 16 has multiple protection functions. It can collect the motor's operating current, operating voltage and speed in real time, and can provide protection measures such as undervoltage protection, overvoltage protection, instantaneous overcurrent protection, overload protection, phase loss protection, overfrequency protection and power device overheat protection. Furthermore, it can adjust the speed by performing PID calculations through the controller and outputting the operating frequency to the frequency converter to achieve constant negative voltage sampling by adjusting the speed.

[0028] The speed control module 16 can be controlled by a frequency converter to monitor whether any abnormalities occur in the main power supply circuit. When an abnormality is detected in the main power supply circuit, the control unit 15 triggers the alarm module 17 to provide an audible and visual alarm. The main power supply circuit specifically refers to the circuit from the power supply to the frequency converter to the main motor. The frequency converter circuit consists of multiple circuits, including an AC / DC module, an IGBT module, a main control board, a voltage detection module, and a current detection module. This combination of hardware and software allows the frequency converter to detect faults such as overvoltage, undervoltage, and overcurrent in the main circuit in real time.

[0029] As an optional implementation, the alarm module 17 provides warning and alarm in the form of audible and visual alarms. The alarm module 17 can emit different types of buzzing sounds when a warning or fault occurs.

[0030] As an optional implementation, the control unit 15 is equipped with a reset button, an emergency stop button, a start button, and a stop button; when the fault is cleared, the fault information is cleared and the fault signal is canceled by using the reset button.

[0031] The control unit 15 mainly consists of two parts: a programmable controller and an interactive human-machine interface (HMI). The programmable controller uses the Siemens S7-1200 series, which acquires data, performs fault warnings and judgments, and implements logic control through programmed programming. The interactive HMI uses a Kunlun Tongtai touchscreen, which displays the status data of various parts of the pump station through a configuration screen.

[0032] The human-machine interface (HMI) is used to display the specific cause and location of warnings or faults. The HMI can display alarm and fault information as well as real-time signal data collected from various parts of the pump station. Preferably, the HMI also allows selection of control modes. In manual mode, the main motor is driven by manually setting the frequency; in automatic mode, the programmable controller uses the pressure value after the orifice plate as feedback, and automatically adjusts the inverter's output frequency through PID control based on the pressure setpoint.

[0033] The control unit 15 can perform system self-tests, monitor whether there are open circuit faults in each sensor, and whether there are communication faults with the frequency converter and the audible and visual alarm, and provide relevant prompts, reducing troubleshooting time and system maintenance difficulty.

[0034] As an optional implementation, the gas pump station monitoring system also includes a skid with an emergency stop button. In case of an emergency, the system can be shut down immediately to ensure personal safety.

[0035] As an optional implementation, the control unit 15 can be executed by a KXJ127(B) control box, which is equipped with a programmable logic controller (PLC) and an interactive human-machine interface. The speed control module 16 is executed by a BPJ3 mine-use explosion-proof and intrinsically safe frequency converter, enabling circuit protection and adjustment of the execution module's operation. The alarm module 17 can be executed by a KXB24 mine-use intrinsically safe audible and visual alarm to indicate system faults or abnormal conditions. The connection relationships of the above-mentioned execution hardware and other hardware in the monitoring system of this application are as follows: The first temperature sensor 1 in the signal acquisition module is connected to the first analog input terminal of the controller 15-KXJ127(B), the second temperature sensor 2 is connected to the second analog input terminal of the controller 15-KXJ127(B), and the third temperature sensor 3 is connected to the third analog input terminal of the controller 15-KXJ127(B). These sensors are used to detect the temperature of the motor.

[0036] The fourth temperature sensor 4 in the signal acquisition module is connected to the fourth analog input terminal of the controller 15-KXJ127(B), the fifth temperature sensor 5 is connected to the fifth analog input terminal of the controller 15-KXJ127(B), and the sixth temperature sensor 9 is connected to the sixth analog input terminal of the controller 15-KXJ127(B). These sensors are used to monitor the surface temperature and bearing temperature of the vacuum pump.

[0037] The first vibration sensor in the signal acquisition module is connected to the seventh analog input terminal of the controller 15-KXJ127(B), the second vibration sensor 6 is connected to the eighth analog input terminal of the controller 15-KXJ127(B), the third vibration sensor 7 is connected to the ninth analog input terminal of the controller 15-KXJ127(B), and the fourth vibration sensor 8 is connected to the tenth analog input terminal of the controller 15-KXJ127(B). These sensors are used to acquire the vibration signal of the vacuum pump.

[0038] The seventh temperature sensor 10 in the signal acquisition module is connected to the eleventh analog input terminal of the controller 15-KXJ127(B) to monitor the temperature of the lubricating oil.

[0039] In the signal acquisition module, the first pressure sensor 11 is connected to the CM1241 module of the 15-KXJ127(B) controller via an RS485 cable, and the second pressure sensor 12 is also connected to the CM1241 module via an RS485 cable. These two sensors are used to monitor the pressure values ​​before and after the orifice plate. The two sensors should be installed as required: the pressure sensor before the orifice plate is installed at ½D before the orifice plate, and the pressure sensor after the orifice plate is installed at 1D after the orifice plate. D represents the pipe diameter. The pressure value after the orifice plate can also be used as the negative pressure feedback value for PID regulation in control mode.

[0040] The methane sensor 14 in the signal acquisition module is connected to the CM1241 module of the 15-KXJ127(B) controller via an RS485 cable to monitor the methane concentration in the external environment.

[0041] The frequency converter is connected to the CB1241 module of the 15-KXJ127(B) controller via an RS485 cable. The controller can collect various detection parameters of the motor from the frequency converter through communication, and can also control the start / stop and frequency or speed setting of the frequency converter through communication. The frequency converter not only achieves stable control of the pumping station, but also monitors the real-time status of the motor, effectively ensuring the safety of the pumping station during operation.

[0042] The motor in the execution module is directly connected to the frequency converter, which drives the motor to rotate, and then drives the vacuum pump through the bearings. The frequency converter can effectively reduce the motor's starting current and control the pumping vacuum level of the pumping station by adjusting the frequency or speed, thus providing better adaptive capability.

[0043] The audible and visual alarm is connected to the CM1241 module of the 15-KXJ127(B) controller via an RS485 cable. When a warning or major fault occurs, the controller can control the alarm to sound different types of beeps via communication, better reminding maintenance personnel to handle the situation as soon as possible. At the same time, the human-machine interface on the 15-KXJ127(B) controller can display the specific cause and location of the alarm or fault.

[0044] Therefore, as Figure 2As shown, the gas pumping station monitoring system of this application includes a monitoring mode and a control mode, mainly composed of a control unit 15, a signal acquisition module, a speed regulation module 16, an execution module, and an alarm module 17. The control unit 15 is used for acquiring and converting sensor signals from different parts of the pumping station (converting analog quantities to digital quantities, for example, converting 4mA-20mA to 0-27648 that can be recognized by a PLC), as well as for logic judgment and process control. It is also equipped with a touch screen for human-machine interaction. The signal acquisition module can monitor different parts of the pumping station in real time. The speed regulation module 16 mainly refers to a frequency converter, which can realize circuit protection and operation control of the execution module. The execution module mainly includes a main motor and a vacuum pump. The main motor is connected to the vacuum pump through bearings and is driven by the frequency converter to achieve gas extraction. The alarm module 17 mainly includes an audible and visual alarm, which can indicate system faults or abnormal states. The gas pumping station monitoring system of this application can comprehensively monitor the operating status of the pumping station and issue timely warnings, and also has built-in different modes to control the operation of the pumping station.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope.
