[0022] 24VDC: Indicates that the voltage level of direct current is 24 volts.

[0023] Secondly, the application scenario of the embodiment of the present application is explained. The present application can be applied to the ventilation system of underground projects such as tunnels and mines, especially the scenario where the air quality needs to be quickly adjusted after blasting. In other words, the target environment includes the ventilation environment of the ventilation system in underground engineering scenarios such as tunnels and mines. The present application can ensure that the air quality in the tunnel after blasting meets the standard and achieve energy saving by automatically adjusting the opening of the air valve; it can not only ensure the work safety of workers after tunnel blasting, but also improve energy utilization efficiency and adapt to ventilation needs under different construction conditions.

[0024] The following will be combined Figure 1 , Figure 2 and Figure 3 , the architecture of the air valve control device of the embodiment of the present application is introduced.

[0025] In one embodiment of the present application, the air valve control device includes an air valve and a controller (ie, a PLC controller), the air valve is communicatively connected to the controller, and the air valve is installed in an air duct of a ventilation system.

[0026] In one embodiment of the present application, the air valve control device also includes a transmission component and a sensor, the air valve is connected to the transmission component, the sensor is connected to the transmission component, and the controller is communicatively connected to a monitoring instrument located in the target environment.

[0027] In the air valve control device of the present application, the PLC controller is responsible for calculating the opening of the air valve and issuing control instructions, the push rod motor (transmission component) executes the opening and closing action of the air valve, and the displacement sensor monitors the actual opening of the air valve in real time and feeds back to the PLC, thereby realizing closed-loop control of the air valve opening. The Lora module is responsible for the communication between the device and the external main control cabinet (terminal device), ensuring the stable and reliable transmission of instructions and feedback signals.

[0028] In one embodiment of the present application, the transmission assembly includes a drive motor, a moving structure and a contactor, the drive motor is connected to the moving structure, the drive motor controls the opening and closing of the air valve through the moving structure, the drive motor is connected to the contactor, and the contactor controls the power on and off of the drive motor; the sensor is a displacement sensor, and the displacement sensor is arranged on the moving structure.

[0029] In one embodiment of the present application, the air valve control device further includes a communication unit, and the communication unit is remotely connected to the terminal device for communication.

[0030] Specifically, the air valve is used to control the gas flow in the ventilation system; the push rod motor (drive motor and mobile structure) is mechanically connected to the air valve to drive the opening and closing of the air valve; the PLC (programmable logic controller) controller is used to control the forward and reverse rotation of the push rod motor to adjust the opening of the air valve; the displacement sensor is used to monitor the actual opening of the air valve and feed back the monitored opening to the PLC controller; the Lora module (communication unit) is used to wirelessly communicate the control instructions and monitoring data with the main control cabinet (terminal device) outside the tunnel; the contactor is used to control the power on and off of the push rod motor. The PLC controller receives instructions from the main control cabinet outside the tunnel, communicates with the main control cabinet through the Lora module, and controls the push rod motor to adjust the opening of the air valve according to the deviation between the actual opening feedback from the displacement sensor and the set target opening.

[0031] Furthermore, the Lora module is connected to the PLC controller through the RS485 interface, and communicates data with the main control cabinet outside the tunnel through multiple signal relay boxes. The push rod motor is controlled by a contactor to realize the forward or reverse drive of the push rod to adjust the opening and closing of the air valve. The PLC controller receives the actual opening feedback information of the air valve through the displacement sensor, and adjusts the action of the push rod motor based on the feedback information so that the opening of the air valve is consistent with the target opening. The set value of the air valve opening is remotely input by the main control cabinet, and the PLC controller dynamically adjusts the air valve opening according to the comparison between the set value and the actual value. The air valve control device is powered by a 380VAC power supply, and the power is converted into a 24V DC voltage through an adapter to power the electronic equipment. When the air valve control device detects a fault in the push rod motor or PLC controller, the air valve will automatically close to prevent poor ventilation or leakage of harmful gases in the tunnel.

[0032] It can be understood that the automatic control principle of the air valve of the present application is as follows: the preset ventilation demand inputs the target opening value of the air valve, and the current actual opening is monitored by the displacement sensor. The PLC controller receives the feedback information of the displacement sensor, calculates the deviation between the target opening and the actual opening, and then issues instructions to control the push rod motor to adjust the opening and closing of the air valve by forward and reverse rotation. The stroke of the push rod motor is controlled by the contactor. When the air valve reaches the target opening, the system stops the action of the push rod motor to ensure that the air valve remains stable at the predetermined opening position.

[0033] This application aims to solve the problems of inaccurate air volume control and energy waste in the prior art. By controlling the push rod motor through PLC and combining the feedback information of the displacement sensor, the opening of the air valve is adjusted in real time to achieve precise control of the air volume. The Lora module is also used to communicate data with the main control cabinet outside the tunnel, making the ventilation control more intelligent and automated, ensuring the safety of the working environment in the tunnel while achieving energy-saving effects.

[0034] The following describes the air valve control method, system, equipment and medium for blasting ventilation in the embodiments of the present application with reference to the accompanying drawings. In view of the problem that the fixed air volume control method is used for ventilation after tunnel blasting in the above-mentioned related art, and it cannot be adjusted according to the actual situation in the tunnel, resulting in poor ventilation effect and high energy consumption in the tunnel, the present application provides a method for controlling air valves for blasting ventilation, in which the opening of the air valve can be adjusted in real time according to the actual situation of the target environment (such as the environment in the tunnel), to ensure that the air quality in the tunnel after blasting meets the standard, and effectively reduce energy consumption, achieve energy-saving effects, and improve energy efficiency while ensuring safety. As a result, the technical problem that the fixed air volume control method is used for ventilation after tunnel blasting in the related art, and it cannot be adjusted according to the actual situation in the tunnel, resulting in poor ventilation effect and high energy consumption in the tunnel is solved.

[0035] The present application automatically adjusts and discharges the generated toxic gases and dust (target gases and dust), accurately controls the opening and closing of air valves during tunnel ventilation, realizes dynamic adjustment of air volume, and ensures the air quality in the tunnel after blasting. At the same time, it can also achieve energy-saving effects and optimize the use efficiency of ventilation energy through intelligent adjustment of the air valve opening.

[0036] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0037] The air valve control method for blasting ventilation described in the preferred embodiment of the present application is as follows: Figure 4 As shown, the air valve control method for blasting ventilation includes the following steps: In step S101, the controller obtains air quality data in a target environment and a current opening of the air valve.

[0038] In a possible implementation, the controller obtains air quality data collected by a monitoring instrument on a target environment; and the controller obtains a current opening degree of the air valve collected by the sensor.

[0039] Specifically, for equipment installation, first install the air valve at the air duct of the tunnel ventilation system, and ensure that the mechanical structure of the air valve is correctly connected to the push rod motor. The push rod motor controls the forward and reverse rotation through the contactor to drive the opening and closing of the air valve. The opening of the air valve is monitored in real time by the displacement sensor installed on the push rod. Install the PLC controller in the control cabinet in the tunnel, and connect the PLC to the Lora module through the RS485 interface. The Lora module transmits the control signals and data in the tunnel to the main control cabinet outside the tunnel through multiple signal relay boxes for remote control and monitoring of the system status. The power part uses a 380VAC power supply, and the voltage is converted into a 24V DC voltage through an adapter to power the PLC controller and other electronic equipment. The power line should ensure a stable and reliable connection with the push rod motor and related sensors.

[0040] Then start and debug the equipment: After the installation is completed, start the air valve control equipment, and first initialize the PLC controller, including inputting the target opening range of the air valve (such as fully open, half open or closed state), and setting the communication parameters with the main control cabinet. After the air valve control equipment is started, the PLC controller automatically adjusts the opening of the air valve according to the preset ventilation requirements (such as the data provided by the air quality monitoring instrument in the tunnel). The PLC drives the push rod motor by controlling the contactor, and the push rod motor drives the air valve to open and close. When the air valve reaches the target opening, the PLC stops the operation of the push rod motor.

[0041] In step S102, the controller determines a target opening of the air valve according to the air quality data and the current opening.

[0042] In a possible implementation, the target opening includes a fully open state, a half-open state, and a closed state. The controller obtains the current concentration of the target gas and dust according to the air quality data and the current opening; when the current concentration exceeds a preset threshold range, the adjustment opening of the air valve is determined to be a fully open state; when the current concentration is within the preset threshold range, the adjustment opening of the air valve is determined to be a half-open state; when the current concentration does not reach the preset threshold range, the adjustment opening of the air valve is determined to be a closed state.

[0043] It is understandable that the present application can flexibly adjust the air volume according to the actual ventilation needs in the tunnel by automatically adjusting the air valve opening, thus avoiding energy waste caused by fixed air volume in traditional ventilation systems. When the concentration of toxic gas and dust is high after tunnel blasting, the air valve is adjusted to a larger opening to increase ventilation and exhaust; when the gas emission reaches the safety standard, the air valve is gradually closed to the energy-saving mode to reduce the fan operation time and energy consumption.

[0044] Specifically, the air valve control device adjusts the air valve opening in real time according to the environment in the tunnel. For example, after the tunnel blasting operation, the concentration of toxic gases and dust generated by the blasting is high, and the air valve is adjusted to the maximum opening to ensure that the harmful gas is discharged as soon as possible. When the gas concentration drops to a safe range, the PLC controller receives the signal from the gas sensor, calculates and instructs the push rod motor to gradually close the air valve to reduce energy consumption. During the adjustment process, the displacement sensor monitors the displacement of the push rod in real time and feeds back the actual opening of the air valve to the PLC controller. The PLC adjusts the operation of the push rod motor by comparing the difference (deviation value) between the actual opening and the set value until the air valve reaches the target opening, forming a closed-loop control system to ensure that the air valve is always in a state of precise control.

[0045] In the automatic energy-saving adjustment, in the initial stage after the tunnel blasting, the air valve control device opens the air valve to the maximum opening to quickly discharge toxic gases and dust. When the air quality in the tunnel reaches the set safety standard, the PLC controller gradually adjusts the air valve to a small opening or closed state based on the information fed back by the sensor, thereby reducing the working time of the fan and achieving the purpose of energy saving. Energy-saving effect monitoring: The air valve control device can also record the opening and closing status of the air valve and the changes in the air quality in the tunnel. By comparing with historical data, the main control cabinet can monitor the energy-saving effect of the system. If it is found that the ventilation system has excessive energy consumption, the main control personnel can adjust the opening and closing strategy of the air valve to achieve more optimized ventilation control.

[0046] In one possible implementation, the controller sends the air quality data and the current opening to a terminal device; the controller receives the target opening value of the air valve set by the terminal device based on the air quality data and the current opening; the controller adjusts the air valve to the target opening value to complete the control of the gas flow in the ventilation system.

[0047] Specifically, during the remote monitoring and management of the air valve control equipment, the air valve control equipment realizes remote communication with the main control cabinet outside the tunnel through the Lora module. The main control cabinet outside the tunnel can monitor the opening status of the air valve in real time and adjust the opening and closing of the air valve when necessary. In addition, the main control cabinet can remotely input a new air valve opening target value according to the changes in the air quality in the tunnel, and instruct the PLC to perform the corresponding adjustment operation. The Lora module ensures stable data transmission through the signal relay box, so that reliable data exchange and remote control can be achieved even in long-distance tunnels.

[0048] In step S103, the controller adjusts the air valve to the target opening to complete the control of the gas flow in the ventilation system.

[0049] In a possible implementation, the controller calculates an opening deviation of the air valve according to the current opening and the target opening; and the controller adjusts the air valve to the target opening according to the opening deviation.

[0050] In a possible implementation, if an abnormal signal of the controller or the transmission component is detected, the controller controls the opening state of the air valve to be adjusted to a closed state.

[0051] Specifically, data communication is carried out with the main control cabinet outside the tunnel through the Lora module. The main control cabinet outside the tunnel can receive the ventilation status data in the tunnel in real time, and can remotely control the air valve opening to ensure effective response to ventilation needs at different tunnel construction stages. In addition, the air valve control equipment supports command transmission through multiple signal relay boxes to ensure the stability and reliability of communication inside and outside the tunnel.

[0052] Furthermore, during the emergency response to faults, the emergency shutdown mechanism can automatically trigger the emergency shutdown mechanism if an abnormality is detected in the push rod motor or PLC controller during the operation of the air valve control device. The PLC controller issues a command to immediately close the air valve to prevent dangerous gas leakage or insufficient ventilation in the tunnel. When the air valve control device fails, the main control cabinet will receive the corresponding alarm signal. Maintenance personnel can remotely diagnose the cause of the fault through the Lora module and take corresponding treatment measures, such as restarting the system or replacing the faulty parts on site.

[0053] This application uses a PLC controller to adjust the action of the push rod motor to adjust the opening of the air valve in real time, and uses a displacement sensor to feedback the actual opening of the air valve to achieve closed-loop control. The Lora module is responsible for wirelessly communicating the control instructions and status data in the tunnel with the main control cabinet outside the tunnel, supporting remote monitoring and control. It can dynamically adjust the air valve opening according to changes in the air quality in the tunnel, quickly discharge toxic gases and dust after blasting, ensure the safety of workers in the tunnel, and automatically reduce the air valve opening after the gas emissions meet safety standards, reduce energy consumption, and achieve energy-saving effects. It is suitable for ventilation control of underground projects such as tunnels and mines, and has the advantages of high degree of automation, significant energy-saving effects, and stable and reliable operation.
