Description

Technical Field

[0001] The present application relates to the technical field of tunnel ventilation, and in particular to a tunnel ventilation method, system, intelligent terminal and storage medium. Background Art

[0002] Tunnel ventilation refers to a ventilation measure carried out inside the tunnel. Its main purpose is to regulate the airflow in the tunnel, discharge harmful gases and smoke, and ensure the freshness and quality of the air in the tunnel.

[0003] In the related technology, during the vertical pipe jacking construction, it is necessary to utilize the static pressure difference or negative pressure effect to generate a flowing wind field with the help of a ventilator, so that air circulation is formed inside the tunnel, thereby achieving the effect of ventilation.

[0004] Regarding the above-mentioned related technologies, when using a ventilator to form an air circulation inside the tunnel, because the power of the ventilator is fixed, while the air quality in the tunnel is constantly changing, using a ventilator to ventilate the tunnel may result in failure to timely update the air in the tunnel or excessively update the air in the tunnel, resulting in poor ventilation effect in the tunnel. There is still room for improvement. Summary of the invention

[0005] In order to improve the ventilation effect of a tunnel, the present application provides a tunnel ventilation method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a tunnel ventilation method, which adopts the following technical solution: A tunnel ventilation method comprising: Obtaining the impurity detection concentration of the tunnel; Determine whether the impurity detection concentration meets the preset reference ventilation concentration requirements; If it does not meet the requirements, the preset ventilation device is controlled to standby, and the preset converging device is controlled to keep converging the ventilation hose in the ventilation device, and the impurity detection concentration of the tunnel is continuously obtained for cyclic judgment; If it meets the requirements, the preset ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, and the impurity detection concentration of the tunnel is continuously obtained for cyclic judgment.

[0007] By adopting the above technical scheme, when it is determined that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, it indicates that the impurity concentration in the air in the tunnel is low. Therefore, the ventilation device is controlled to standby, and the converging device is controlled to converge the ventilation hose, so as to prevent the ventilation hose from sagging and causing construction inconvenience; when it meets the requirements of the benchmark ventilation concentration, it indicates that there are more impurities in the tunnel. Therefore, the ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, so as to timely update the air in the tunnel, thereby improving the ventilation effect of the tunnel.

[0008] Optionally, the ventilation device includes an air inlet component and an air outlet component, and the step of controlling the preset ventilation device to ventilate the tunnel according to the impurity detection concentration includes: Determine the tunnel ventilation volume based on the impurity detection concentration and the preset concentration-ventilation relationship; Obtaining the ventilation volume of the ventilation device before adjustment; Determine whether the ventilation volume before adjustment meets the tunnel ventilation volume requirements; If it meets the requirements, the air inlet and outlet components are controlled to ventilate the tunnel; If not, obtain the device diameter value of the ventilation device; Analyze the tunnel ventilation volume and device diameter to control the adjustment of air inlet and outlet components; Control the air inlet and outlet components to ventilate the tunnel.

[0009] By adopting the above technical scheme, the tunnel ventilation volume is determined according to the impurity detection concentration and the concentration-ventilation relationship. When it is determined that the ventilation volume before adjustment meets the requirements of the tunnel ventilation volume, it indicates that the ventilation device can directly meet the ventilation needs of the tunnel. Therefore, the air inlet component and the air outlet component are controlled to ventilate the tunnel; when it does not meet the requirements of the tunnel ventilation volume, the air inlet component and the air outlet component are adjusted to ventilate the tunnel, thereby preventing insufficient or excessive ventilation of the tunnel, thereby improving the ventilation effect of the tunnel.

[0010] Optionally, the step of analyzing the tunnel ventilation volume and the device diameter value to control the adjustment of the air inlet component and the air outlet component includes: Analyze the tunnel ventilation volume and preset air velocity values ​​to determine the actual ventilation diameter values ​​of the air inlet and outlet components; Analyze the device diameter value and the actual ventilation diameter value to determine the component adjustment diameter values ​​of the air inlet component and the air outlet component; According to the diameter value of the component adjustment, the valves in the air inlet component and the air outlet component are controlled for adjustment; According to the diameter adjustment value of the component, the preset mechanical arm is controlled to adjust the diameter of the ventilation hose in the air inlet component and the air outlet component.

[0011] By adopting the above technical scheme, the actual ventilation diameter values ​​of the air inlet and air outlet components are determined after analyzing the tunnel ventilation volume and air flow rate values, and then the component adjustment diameter value is calculated based on the device diameter value and the actual ventilation diameter value. The valves and ventilation hoses in the air inlet and air outlet components are adjusted according to the component adjustment diameter value to ensure that the ventilation volume of the air inlet and air outlet components is consistent with the tunnel ventilation volume, thereby improving the ventilation effect of the tunnel.

[0012] Optionally, the step of controlling the air inlet assembly and the air outlet assembly to ventilate the tunnel includes: Get the ventilation properties of the air inlet component and the air outlet component; Determine whether the ventilation properties meet the requirements of the preset initial ventilation properties; If it meets the requirements, the constriction device is controlled to loosen the ventilation hoses in the air inlet assembly and the air outlet assembly, and output a ventilation start trigger signal; If it does not meet the requirements, the ventilation trigger signal will be directly output; The air inlet and outlet components are controlled according to the ventilation start trigger signal to ventilate the tunnel.

[0013] By adopting the above technical scheme, when the ventilation properties meet the requirements of the initial ventilation properties, it indicates that the air inlet assembly and the air outlet assembly have just been started, so the convergence device is controlled to relax the ventilation hose, thereby ensuring the ventilation of the ventilation hose, and then the air inlet assembly and the air outlet assembly are controlled to ventilate the tunnel; when the requirements of the initial ventilation properties are not met, the air inlet assembly and the air outlet assembly are directly controlled to ventilate the tunnel, thereby improving the ventilation effect of the tunnel.

[0014] Optionally, the step of controlling the air inlet assembly and the air outlet assembly to ventilate the tunnel according to the ventilation start trigger signal includes: According to the ventilation start trigger signal and the preset heating static trigger signal, the air outlet component is controlled to discharge the air in the tunnel out of the tunnel; Acquiring air parameters outside the tunnel based on a ventilation start trigger signal; The air inlet assembly is controlled according to the air parameters outside the tunnel to deliver the air outside the tunnel into the tunnel.

[0015] By adopting the above technical solution, the air outlet component is controlled to discharge the air in the tunnel out of the tunnel, and the air inlet component is controlled to send the air outside the tunnel into the tunnel, so that the air in the tunnel forms a circulating airflow, thereby constantly refreshing the air in the tunnel, thereby improving the ventilation effect of the tunnel.

[0016] Optionally, the step of controlling the air inlet assembly to deliver the air outside the tunnel into the tunnel according to the air parameters outside the tunnel includes: Determine whether the air parameters outside the tunnel meet the requirements of the preset required air temperature value; If yes, then determine whether the air parameters outside the tunnel meet the preset requirements of the required air impurity concentration; If the required air impurity concentration is met, the air inlet assembly is directly controlled to send the air outside the tunnel into the tunnel; If the required air impurity concentration does not meet the requirements, the preset filter device is controlled to start, and the air intake component is controlled to draw air outside the tunnel into the filter device for filtration and then send it into the tunnel; If not, the preset heating device is controlled to start according to the air parameters outside the tunnel and the required air temperature value, and it is judged whether the air parameters outside the tunnel meet the preset required air impurity concentration requirements; If the required air impurity concentration is met, the air inlet assembly is controlled to draw air outside the tunnel into the heating device for heating and then send it into the tunnel; If the required air impurity concentration does not meet the requirements, the preset filtering device is controlled to start, and the air inlet component is controlled to draw the air outside the tunnel into the filtering device and the heating device in turn for filtration and heating, and then send it into the tunnel.

[0017] By adopting the above technical scheme, when the air parameters outside the tunnel meet the requirements of the required air temperature value, but do not meet the requirements of the required air impurity concentration, the air intake component is controlled to draw the air outside the tunnel into the filter device for filtration and then send it into the tunnel, thereby ensuring that the air entering the tunnel is fresh and qualified; and when the air parameters outside the tunnel do not meet the requirements of the required air temperature value, and do not meet the requirements of the required air impurity concentration, the air intake component is controlled to draw the air outside the tunnel into the filter device and the heating device in turn for filtration and heating and then send it into the tunnel, thereby ensuring that the temperature of the air entering the tunnel is comfortable, thereby improving the ventilation effect of the tunnel.

[0018] Optionally, the step of controlling the start of a preset heating device according to the air parameters outside the tunnel and the required air temperature value includes: Analyze the air parameters outside the tunnel and the required air temperature values ​​to determine the temperature value that needs to be increased; Determine the heating power value according to the temperature value to be increased and the preset temperature-power relationship; The heating device is controlled to start according to the heating power value.

[0019] By adopting the above technical scheme, the heating power value is determined according to the relationship between the temperature value to be increased and the temperature power, so that the start-up of the heating device is controlled according to the heating power value, ensuring that the heating temperature of the air by the heating device is equal to the required air temperature value without causing the temperature to be too high or too low, thereby improving the convenience of controlling the heating device.

[0020] In a second aspect, the present application provides a tunnel ventilation system, which adopts the following technical solution: A tunnel ventilation system, comprising: An acquisition module, used to obtain the impurity detection concentration; A memory for storing a program of a tunnel ventilation method as described in any one of the above items; The program in the memory can be loaded and executed by the processor to implement a tunnel ventilation method as described in any one of the above items.

[0021] By adopting the above technical solution, the processor loads and executes a program of a tunnel ventilation method stored in the memory, so that the acquisition module obtains a series of data related to tunnel ventilation. When it is determined that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, it indicates that the impurity concentration in the air in the tunnel is low. Therefore, the ventilation device is controlled to standby, and the convergence device is controlled to converge the ventilation hose, so as to prevent the ventilation hose from sagging and causing construction inconvenience; when it meets the requirements of the benchmark ventilation concentration, it indicates that there are more impurities in the tunnel. Therefore, the ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, so as to timely update the air in the tunnel, thereby improving the ventilation effect of the tunnel.

[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a tunnel ventilation method as described in any one of the above items.

[0023] By adopting the above technical solution, by operating the intelligent terminal, the processor loads and executes a computer program of a tunnel ventilation method stored in the memory, so that when it is determined that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, it indicates that the impurity concentration in the air in the tunnel is low, so the ventilation device is controlled to standby, and the convergence device is controlled to converge the ventilation hose, so as to prevent the ventilation hose from sagging and causing construction inconvenience; when it meets the requirements of the benchmark ventilation concentration, it indicates that there are more impurities in the tunnel, so the ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, so as to timely update the air in the tunnel, thereby improving the ventilation effect of the tunnel.

[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which is convenient for improving the ventilation effect of a tunnel, and adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned tunnel ventilation methods.

[0025] By adopting the above technical scheme, a computer program of a tunnel ventilation method is stored in a computer-readable storage medium, so that the processor loads and executes the computer program in the storage medium. When it is determined that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, it indicates that the impurity concentration in the air in the tunnel is low. Therefore, the ventilation device is controlled to standby, and the converging device is controlled to converge the ventilation hose, so as to prevent the ventilation hose from sagging and causing construction inconvenience. When it meets the requirements of the benchmark ventilation concentration, it indicates that there are more impurities in the tunnel. Therefore, the ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, so as to timely update the air in the tunnel, thereby improving the ventilation effect of the tunnel.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When it is determined that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, it indicates that the impurity concentration in the air in the tunnel is low, so the ventilation device is controlled to standby, and the converging device is controlled to converging the ventilation hose, so as to prevent the ventilation hose from sagging and causing construction inconvenience; when it meets the requirements of the benchmark ventilation concentration, it indicates that there are more impurities in the tunnel, so the ventilation device is controlled to ventilate the tunnel according to the impurity detection concentration, so as to timely update the air in the tunnel, thereby improving the ventilation effect of the tunnel; The actual ventilation diameter values ​​of the air inlet and air outlet components are determined by analyzing the tunnel ventilation volume and air flow rate values, and then the component adjustment diameter values ​​are calculated based on the device diameter value and the actual ventilation diameter value, so as to adjust the valves and ventilation hoses in the air inlet and air outlet components according to the component adjustment diameter values, so as to ensure that the ventilation volume of the air inlet and air outlet components is consistent with the tunnel ventilation volume, thereby improving the ventilation effect of the tunnel; By controlling the air outlet component to discharge the air in the tunnel out of the tunnel, and controlling the air inlet component to send the air outside the tunnel into the tunnel, the air in the tunnel forms a circulating airflow, thereby constantly refreshing the air in the tunnel and further improving the ventilation effect of the tunnel.

[0037] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] A tunnel ventilation method is disclosed in an embodiment of the present application, specifically disclosing a monitoring and control system 5, a convergence device 13, a ventilation device 3 and a concentration monitor 6. The monitoring and control system 5 is respectively connected to the convergence device 13, the ventilation device 3 and the concentration monitor 6 through data wires to realize data interaction and control. The concentration monitor 6 detects the impurity detection concentration in the tunnel 1 and sends it to the monitoring and control system 5. When the monitoring and control system 5 determines that the impurity detection concentration does not meet the requirements of the benchmark ventilation concentration, the ventilation device 3 is controlled to standby, and the convergence device 13 is maintained to converge the ventilation hose 7 in the ventilation device 3; when it meets the requirements of the benchmark ventilation concentration, the ventilation device 3 is controlled to ventilate the tunnel 1 according to the impurity detection concentration, thereby ensuring that the air in the tunnel 1 is fresh and qualified, thereby improving the ventilation effect of the tunnel 1.

[0039] Reference Figure 1 , the embodiment of the present application discloses a tunnel ventilation method, comprising the following steps: Step S100: obtaining the impurity detection concentration of tunnel 1.

[0040] The impurity detection concentration refers to the concentration of smoke and harmful gases in tunnel 1. Figure 8 , which is detected by the concentration monitor 6 installed in the tunnel 1 and the vertical jacking pipe 2 and sent to the monitoring and control system 5.

[0041] Step S101: Determine whether the impurity detection concentration meets the requirements of the preset reference ventilation concentration.

[0042] The reference ventilation concentration refers to the minimum impurity concentration required for ventilation of the tunnel 1. The specific value is determined by the operator according to the actual situation. The reference ventilation concentration requirement refers to not being lower than the reference ventilation concentration.

[0043] The monitoring control system 5 determines whether the impurity detection concentration is not lower than the reference ventilation concentration, thereby determining whether there is too much smoke and harmful gases in the tunnel 1.

[0044] Step S1011: If not, the preset ventilation device 3 is controlled to standby, and the preset converging device 13 is controlled to keep converging the ventilation hose 7 in the ventilation device 3, and the impurity detection concentration of the tunnel 1 is continuously obtained for cyclic judgment.

[0045] Among them, if the monitoring and control system 5 determines that the impurity detection concentration is lower than the benchmark ventilation concentration, it indicates that there are too few smoke and harmful gases in the tunnel 1, and therefore there is no need to ventilate the tunnel 1, thereby controlling the ventilation device 3 to standby, and controlling the converging device 13 to maintain the ventilation hose 7 in the converging ventilation device 3, thereby preventing the ventilation hose 7 from sagging and causing construction inconvenience, and continuing to detect the impurity detection concentration of the tunnel 1, thereby continuously monitoring the air conditions of the tunnel 1.

[0046] Reference Figure 8 and Fig. 9 The ventilation device 3 refers to a device for realizing ventilation of the tunnel 1, including an air inlet assembly 32 and an air outlet assembly 31. The air inlet assembly 32 is actually the same as the air outlet assembly 31. The energy supply for air inlet and air supply is defined by the operator, including a fan 18, a ventilation hose 7, a valve 4, a support arm 10, a tunnel 1 side wall connector and a top pipe lateral connector 12. The fan 18 is used to suck the air in the tunnel 1 into the ventilation hose 7 or to suck the air in the ventilation hose 7 into the tunnel 1; the valve 4 is used to control the opening and closing of the ventilation hose 7 and the ventilation volume; the tunnel 1 side wall connector is fixed to the inner surface of the tunnel 1, and one end of the support arm 10 is connected to the valve 4, and the other end is connected to the tunnel 1 side wall connector, from The ventilation hose 7 is fixed on the inner surface of the tunnel 1; the lateral connector 12 of the top pipe is fixed on the inner surface of the vertical top pipe 2, and one end of the support arm 10 is connected to the valve 4, and the other end is connected to the lateral connector 12 of the top pipe, so that the ventilation hose 7 is fixed to the vertical top pipe 2; a filter device 16 and a heating device 17 are sequentially arranged on the ventilation hose 7, and the filter device 16 can adopt an air filter screen, one end of the filter device 16 is connected to the fan 18, and the other end of the filter device 16 is connected to the heating device 17 through the ventilation software, and the other end of the heating device 17 is connected to the valve 4 through the ventilation hose 7, and the heating device 17 can adopt a heating wire arranged in the heating box to heat the air.

[0047] Reference Figure 8 and Fig. 9The gathering device 13 refers to a device for gathering the ventilation hose 7, including a telescopic arm 14 and a hose locking ring 15. The telescopic arm 14 is respectively hinged with the valve 4 and the hose locking ring 15 to achieve relative rotation. The telescopic arm 14 can adopt a hydraulic rod, which is composed of a telescopic outer arm and a built-in hydraulic extension arm, and can be controlled to be telescopic. When the telescopic arm 14 is extended, the hose locking ring 15 reaches the middle of the ventilation hose 7 to prevent the ventilation of the ventilation hose 7 from being affected. When the telescopic arm 14 is retracted, the hose locking ring 15 tightens the ventilation hose 7 to prevent the ventilation hose 7 from sagging and affecting the construction.

[0048] Step S1012: If it meets the requirements, the preset ventilation device 3 is controlled to ventilate the tunnel 1 according to the impurity detection concentration, and the impurity detection concentration of the tunnel 1 is continuously obtained for cyclic judgment.

[0049] If the monitoring and control system 5 determines that the impurity detection concentration is not lower than the reference ventilation concentration, it indicates that there are too much smoke and harmful gases in the tunnel 1. Therefore, the ventilation device 3 is controlled to ventilate the tunnel 1 according to the impurity detection concentration. The specific method is as follows. Figure 2 The steps are performed, and the impurity detection concentration in the tunnel 1 is continued to be detected, so as to continuously pay attention to the changes in the air in the tunnel 1.

[0050] The ventilation device 3 in this step is consistent with the ventilation device 3 in step S1011, and will not be described in detail here.

[0051] Reference Figure 2 The ventilation device 3 includes an air inlet component 32 and an air outlet component 31. The steps of controlling the preset ventilation device 3 to ventilate the tunnel 1 according to the impurity detection concentration include: Step S200: Determine the tunnel ventilation volume according to the impurity detection concentration and a preset concentration-ventilation relationship.

[0052] Among them, the concentration-ventilation relationship refers to the coefficient of the corresponding relationship between impurity concentration and ventilation volume. The higher the impurity concentration, the greater the ventilation volume. The specific value of the coefficient is determined by the operator based on actual conditions.

[0053] The tunnel ventilation volume refers to the ventilation volume that effectively reduces the impurity concentration in the tunnel 1. The monitoring and control system 5 calculates the product of the impurity detection concentration and the corresponding coefficient of the concentration-ventilation relationship to obtain the tunnel ventilation volume.

[0054] Step S201: obtaining the ventilation volume of the ventilation device 3 before adjustment.

[0055] The ventilation volume before adjustment refers to the current ventilation volume of the ventilation device 3 , which is obtained by the monitoring and control system 5 calling the ventilation volume of the ventilation device 3 last time.

[0056] Step S202: Determine whether the ventilation volume before adjustment meets the tunnel ventilation volume requirement.

[0057] The requirement of tunnel ventilation volume refers to being equal to the tunnel ventilation volume. The monitoring control system 5 determines whether the ventilation volume before adjustment is equal to the tunnel ventilation volume, thereby determining whether the ventilation device 3 needs to adjust the ventilation volume before ventilating the tunnel 1.

[0058] Step S2021: If it is met, the air inlet assembly 32 and the air outlet assembly 31 are controlled to ventilate the tunnel 1 .

[0059] If the monitoring and control system 5 determines that the ventilation volume before adjustment is equal to the tunnel ventilation volume, it indicates that the ventilation device 3 does not need to adjust the ventilation volume before ventilating the tunnel 1, so the air inlet component 32 and the air outlet component 31 are controlled to ventilate the tunnel 1. For specific methods, refer to Figure 4 steps.

[0060] Step S2022: If not, obtain the device diameter value of the ventilation device 3.

[0061] Among them, if the monitoring and control system 5 determines that the ventilation volume before adjustment is not equal to the tunnel ventilation volume, it means that the current ventilation volume of the ventilation device 3 is too much or too little, so the device diameter value of the ventilation device 3 is detected to provide data support for subsequent adjustment of the ventilation device 3.

[0062] The device diameter value refers to the ventilation diameter of the ventilation hose 7 and the valve 4 in the ventilation device 3, and is obtained by the monitoring and control system 5 identifying and calling the diameter value of the ventilation device 3 that was adjusted last time.

[0063] Step S203: Analyze the tunnel ventilation volume and the device diameter value to control the air inlet component 32 and the air outlet component 31 to make adjustments.

[0064] After the monitoring and control system 5 obtains the device diameter value, the monitoring and control system 5 adjusts the air inlet component 32 and the air outlet component 31 according to the tunnel ventilation volume and the device diameter value. The specific method is as follows Figure 3 steps, so that the ventilation volume of the air inlet component 32 and the air outlet component 31 is consistent with the ventilation volume of the tunnel, thereby effectively reducing the impurity concentration in the tunnel 1.

[0065] Step S204: Control the air inlet assembly 32 and the air outlet assembly 31 to ventilate the tunnel 1 .

[0066] After adjusting the air inlet assembly 32 and the air outlet assembly 31, the air inlet assembly 32 and the air outlet assembly 31 are controlled to ventilate the tunnel 1. For specific methods, refer to Figure 4 steps, thereby effectively reducing the impurity concentration in the tunnel 1 and ensuring that the air in the tunnel 1 is fresh and qualified.

[0067] Reference Figure 3The steps of analyzing the tunnel ventilation volume and the device diameter value to control the air inlet component 32 and the air outlet component 31 to adjust include: Step S300: Analyze the tunnel ventilation volume and the preset air flow rate value to determine the actual ventilation diameter values ​​of the air inlet component 32 and the air outlet component 31.

[0068] Among them, the actual ventilation diameter value refers to the diameter of the device when the air inlet component 32 and the air outlet component 31 are ventilated. The monitoring and control system 5 calculates the quotient of the tunnel ventilation volume and the air flow rate value to obtain the cross-sectional area of ​​the device at this time, and then calculates the diameter value based on the area formula of the circle and the cross-sectional area.

[0069] Step S301: Analyze the device diameter value and the actual ventilation diameter value to determine the component adjustment diameter values ​​of the air inlet component 32 and the air outlet component 31.

[0070] Among them, the component adjustment diameter value refers to the diameter value that needs to be adjusted for the air inlet component 32 and the air outlet component 31, which is obtained by calculating the difference between the actual ventilation diameter value and the device diameter value by the monitoring and control system 5. The difference can be positive or negative. If the difference is positive, it indicates that it needs to be increased. If the difference is negative, it indicates that it needs to be decreased.

[0071] Step S302: Control the valves 4 in the air inlet component 32 and the air outlet component 31 to adjust according to the component adjustment diameter value.

[0072] Among them, after determining the component adjustment diameter value, the monitoring and control system 5 controls the valves 4 in the air inlet component 32 and the air outlet component 31 to adjust the opening size according to the component adjustment diameter value, so as to meet the ventilation volume demand.

[0073] Step S303: controlling the preset mechanical arm 9 to adjust the diameter of the ventilation hose 7 in the air inlet component 32 and the air outlet component 31 according to the component adjustment diameter value.

[0074] Among them, after determining the component adjustment diameter value, the monitoring and control system 5 controls the robot arm 9 to pull the ventilation hose 7 outward or compress it inward according to the component adjustment diameter value, thereby adjusting the diameter of the ventilation hose 7 to adapt to the change in the opening degree of the valve 4 to meet the ventilation volume requirements.

[0075] Reference Figure 8 and Fig. 9 The mechanical arm 9 refers to the mechanical arm 9 used to adjust the ventilation hose 7. One end of the mechanical arm 9 is fixed to the valve 4 through the mechanical arm connecting piece 8, and the other end of the mechanical arm 9 is connected to the surface of the ventilation hose 7, so that the diameter of the ventilation hose 7 can be adjusted during the pulling and compression of the mechanical arm 9.

[0076] Reference Figure 4The steps of controlling the air inlet assembly 32 and the air outlet assembly 31 to ventilate the tunnel 1 include: Step S400: Acquire the ventilation properties of the air inlet component 32 and the air outlet component 31.

[0077] The ventilation attribute refers to the ventilation time of the air inlet component 32 and the air outlet component 31, which is obtained by timing by a timer.

[0078] Step S401: Determine whether the ventilation properties meet the requirements of the preset initial ventilation properties.

[0079] The initial ventilation attribute refers to the time when the air inlet component 32 and the air outlet component 31 start ventilation, that is, zero, and the requirement for the initial ventilation attribute refers to being consistent with the initial ventilation attribute.

[0080] By monitoring the control system 5, it is determined whether the ventilation properties are consistent with the initial ventilation properties, thereby determining whether the air inlet component 32 and the air outlet component 31 have just been started.

[0081] Step S4011: If it is met, the converging device 13 is controlled to loosen the ventilation hose 7 in the air inlet assembly 32 and the air outlet assembly 31, and output a ventilation start trigger signal.

[0082] Among them, if the monitoring and control system 5 determines that the ventilation properties are consistent with the initial ventilation properties, it indicates that the air inlet component 32 and the air outlet component 31 have just been started, so the telescopic arm 14 in the convergence device 13 is controlled to extend to the soft middle part of the ventilation pipe, so that the hose locking ring 15 loosens the ventilation hose 7 to prevent affecting the ventilation of the ventilation hose 7, and detects the ventilation start trigger signal to provide a specific time for subsequent ventilation.

[0083] The ventilation start trigger signal is a signal for starting ventilation of the tunnel 1 , and in this step, the signal is output to the monitoring and control system 5 when the telescopic arm 14 is extended to the middle part of the ventilation hose 7 .

[0084] Step S4012: If not met, directly output a ventilation start trigger signal.

[0085] Among them, if the monitoring and control system 5 determines that the ventilation properties are inconsistent with the initial ventilation properties, it means that the air inlet component 32 and the air outlet component 31 have been ventilated for a period of time. The change is caused by the change in impurity concentration. Therefore, the ventilation trigger signal is directly output to provide a specific time for subsequent ventilation.

[0086] The ventilation start trigger signal in this step is consistent with the ventilation start trigger signal in step S4011 and is directly activated by the monitoring and control system 5 .

[0087] Step S402: Control the air inlet assembly 32 and the air outlet assembly 31 to ventilate the tunnel 1 according to the ventilation start trigger signal.

[0088] After the monitoring and control system 5 receives the ventilation start trigger signal, the monitoring and control system 5 responds to the ventilation start trigger signal and controls the air inlet assembly 32 and the air outlet assembly 31 to ventilate the tunnel 1. For specific methods, refer to Figure 5 steps, thereby efficiently renewing the air in the tunnel 1.

[0089] Reference Figure 5 The steps of controlling the air inlet assembly 32 and the air outlet assembly 31 to ventilate the tunnel 1 according to the ventilation start trigger signal include: Step S500 : controlling the air outlet assembly 31 to discharge the air in the tunnel 1 out of the tunnel 1 according to the ventilation start trigger signal and the preset heating static trigger signal.

[0090] Among them, when the monitoring and control system 5 detects the ventilation start trigger signal, the fan 18 of the air outlet component 31 is controlled to start, and the air in the tunnel 1 is drawn into the filter device 16 for filtration according to the air flow rate value. At the same time, the heating device 17 is turned off according to the heating static trigger signal, and finally the air in the tunnel 1 is discharged from the tunnel 1.

[0091] The heating standstill trigger signal refers to a signal for controlling the heating device 17 to standby, and is stored in the monitoring and control system 5 by the operator.

[0092] Step S501: Acquire air parameters outside the tunnel based on a ventilation start trigger signal.

[0093] When the monitoring and control system 5 detects a ventilation trigger signal, the air parameters outside the tunnel are detected to provide data support for the subsequent control of the air intake component 32 to send air outside the tunnel 1 into the tunnel 1.

[0094] The air parameters outside the tunnel refer to the temperature and impurity concentration of the air outside the tunnel 1 , which are detected by a temperature sensor and a concentration monitor 6 installed outside the tunnel 1 and sent to the monitoring and control system 5 .

[0095] Step S502: Control the air inlet assembly 32 to deliver the air outside the tunnel 1 into the tunnel 1 according to the air parameters outside the tunnel.

[0096] After the monitoring and control system 5 receives the air parameters outside the tunnel, the monitoring and control system 5 controls the air inlet assembly 32 to send the air outside the tunnel 1 into the tunnel 1 according to the air parameters outside the tunnel. The specific method is as follows: Figure 6 steps, thereby completing the air circulation of tunnel 1.

[0097] Reference Figure 6The step of controlling the air inlet assembly 32 to deliver the air outside the tunnel 1 into the tunnel 1 according to the air parameters outside the tunnel includes: Step S600: Determine whether the air parameters outside the tunnel meet the requirements of the preset required air temperature value.

[0098] The required air temperature value refers to the air temperature value required during construction in the tunnel 1. The specific value is determined by the operator according to the actual situation. The requirement for the required air temperature value refers to not being lower than the required air temperature value.

[0099] By monitoring the control system 5, it is determined whether the air temperature corresponding to the air parameters outside the tunnel is not lower than the required air temperature value, thereby determining whether the air temperature outside the tunnel 1 is too low.

[0100] Step S601: If yes, determine whether the air parameters outside the tunnel meet the preset required air impurity concentration requirements.

[0101] The required air impurity concentration refers to the allowable concentration of smoke and harmful gases during construction in Tunnel 1. The specific value is determined by the operator based on actual conditions. The requirement for the required air impurity concentration refers to not exceeding the required air impurity concentration.

[0102] If the monitoring and control system 5 determines that the air temperature corresponding to the air parameters outside the tunnel is not lower than the required air temperature value, it means that the air temperature outside the tunnel 1 can be used directly. At this time, the heating device 17 is on standby, and the monitoring and control system 5 determines whether the impurity concentration corresponding to the air parameters outside the tunnel does not exceed the required air impurity concentration, thereby determining that the impurity concentration of the air outside the tunnel 1 meets the requirements for direct use, and further determining the control method for the filtering device 16.

[0103] Step S6011: If the required air impurity concentration is met, the air inlet assembly 32 is directly controlled to send the air outside the tunnel 1 into the tunnel 1 .

[0104] Among them, if the monitoring and control system 5 determines that the impurity concentration corresponding to the air parameters outside the tunnel does not exceed the required air impurity concentration, it means that the impurity concentration of the air outside the tunnel 1 meets the requirements for direct use. Therefore, the fan 18 in the air inlet component 32 is controlled to directly send the air outside the tunnel 1 into the tunnel 1 through the ventilation hose 7, and the filtering device 16 can be on standby.

[0105] Step S6012: If the required air impurity concentration does not meet the requirement, the preset filter device 16 is controlled to start, and the air intake assembly 32 is controlled to draw the air outside the tunnel 1 into the filter device 16 for filtration and then send it into the tunnel 1.

[0106] Among them, if the monitoring and control system 5 determines that the impurity concentration corresponding to the air parameters outside the tunnel exceeds the required air impurity concentration, it indicates that the impurity concentration of the air outside the tunnel 1 does not meet the requirements for direct use. Therefore, the filter device 16 is controlled to start, and the fan 18 in the air inlet component 32 is controlled to draw the air outside the tunnel 1 into the filter device 16 for filtration, and then send the clean air into the tunnel 1.

[0107] The filtering device 16 refers to a device for filtering the air outside or inside the tunnel 1 , and reference is made to the explanation of the filtering device 16 in step S1011 .

[0108] Step S602: If not, the preset heating device 17 is controlled to start according to the air parameters outside the tunnel and the required air temperature value, and it is determined whether the air parameters outside the tunnel meet the preset required air impurity concentration requirements.

[0109] If the monitoring and control system 5 determines that the air temperature corresponding to the air parameters outside the tunnel is lower than the required air temperature value, it indicates that the air temperature outside the tunnel 1 is low and needs to be heated before being sent into the tunnel 1. Therefore, the heating device 17 is controlled to start according to the air parameters outside the tunnel and the required air temperature value. For specific methods, refer to Figure 7 and determine whether the impurity concentration corresponding to the air parameters outside the tunnel does not exceed the required air impurity concentration, thereby determining that the impurity concentration of the air outside the tunnel 1 meets the requirements for direct use, and further determining the control method for the filter device 16.

[0110] The heating device 17 is a device for heating the air outside the tunnel 1. Refer to the explanation of the heating device 17 in step S1011. The required air impurity concentration and the required air impurity concentration requirements in this step are consistent with the required air impurity concentration and the required air impurity concentration requirements in step S601, and are not repeated here.

[0111] Step S6021: If the required air impurity concentration is met, the air inlet assembly 32 is controlled to draw air outside the tunnel 1 into the heating device 17 to heat the air and then send it into the tunnel 1.

[0112] Among them, if the monitoring and control system 5 determines that the impurity concentration corresponding to the air parameters outside the tunnel 1 does not exceed the required air impurity concentration, it means that the impurity concentration of the air outside the tunnel 1 meets the requirements for direct use. Therefore, the fan 18 in the air inlet component 32 is controlled to directly heat the air outside the tunnel 1 in the heating device 17 through the ventilation hose 7 and then send it into the tunnel 1, while the filtering device 16 can be on standby.

[0113] Step S6022: If the required air impurity concentration does not meet the requirement, the preset filter device 16 is controlled to start, and the air inlet assembly 32 is controlled to draw the air outside the tunnel 1 into the filter device 16 and the heating device 17 in turn for filtration and heating before being sent into the tunnel 1.

[0114] Among them, if the monitoring and control system 5 determines that the impurity concentration corresponding to the air parameters outside the tunnel 1 exceeds the required air impurity concentration, it means that the impurity concentration of the air outside the tunnel 1 does not meet the requirements for direct use. Therefore, the filter device 16 is controlled to start, and the fan 18 in the air intake assembly 32 is controlled to draw the air outside the tunnel 1 into the filter device 16 for filtration in turn, and then the filtered air is drawn into the heating device 17 for heating and then sent into the tunnel 1.

[0115] The filtering device 16 in this step is the same as the filtering device 16 in step S6012, and will not be described in detail here.

[0116] Reference Figure 7 The steps of controlling the start-up of the preset heating device 17 according to the air parameters outside the tunnel and the required air temperature value include: Step S700: Analyze the air parameters outside the tunnel and the required air temperature value to determine the temperature value that needs to be increased.

[0117] The temperature value to be increased refers to the temperature value of the air outside the tunnel 1 that needs to be increased, which is obtained by calculating the difference between the required air temperature value and the air temperature value corresponding to the air parameter outside the tunnel by the monitoring and control system 5 .

[0118] Step S701: determining a heating power value according to a temperature value to be increased and a preset temperature-power relationship.

[0119] The temperature-power relationship refers to the coefficient of the corresponding relationship between the temperature to be increased and the heating power. The greater the temperature to be increased, the greater the heating power. The specific coefficient is determined by the operator according to the actual situation. The heating power value refers to the power value of the heating device 17 heating the air outside the tunnel 1, which is calculated by the monitoring and control system 5 as the product of the temperature value to be increased and the corresponding coefficient of the temperature-power relationship.

[0120] Step S702: Control the heating device 17 to start according to the heating power value.

[0121] Among them, after determining the heating power value, the monitoring and control system 5 controls the heating device 17 to heat the air outside the tunnel 1 with the heating power value, so that the temperature of the air rises to the required temperature, ensuring the air temperature requirement in the tunnel 1.
