[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] It should be noted that, although the functional modules are divided in the system schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] refer to Figure 1 , Figure 1 This is a flow chart of the steps of the tunnel ventilation equipment monitoring method. The tunnel ventilation equipment monitoring method is mainly operated by an intelligent device. When the intelligent device is operated, the steps that can be performed include:

[0028] Step 1: Obtain an average speed of traffic in a target tunnel in a target direction, and record the average speed as a target average speed.

[0029] For the target tunnel, it generally has one direction or two directions depending on the design of the road. That is, the traffic generally flows from one end of the target tunnel to the other end; or, the traffic flows from the other end of the target tunnel to one end. For the ventilation design of the target tunnel, the ventilation design in one direction is generally considered. Moreover, the ventilation design in this direction is consistent with the direction of the current traffic. Therefore, in this specific embodiment, a single direction is considered. For the convenience of description, the direction to be studied in this specific embodiment is recorded as the target direction.

[0030] Since the traffic management system monitors the average speed of the traffic in the target direction of the target tunnel in real time, the smart device only needs to obtain the average speed of the traffic in the target direction of the target tunnel from the traffic management system through the Internet. For the convenience of description, the obtained average speed of the traffic is recorded as the target average speed.

[0031] Step 2: determining the wind pressure compensation amount according to the target average speed.

[0032] As the traffic moves in the target tunnel, its average speed will affect the wind pressure in the target tunnel. Through research, it is found that in the target direction, the traffic will have a positive impact on the wind pressure in the target tunnel. When the average speed of the traffic is greater, the wind speed in the target tunnel in the target direction is greater. Therefore, when considering the wind pressure of the target tunnel in the target direction, it is necessary to consider the impact of the target average speed. This impact is reflected by the wind pressure compensation amount.

[0033] The wind pressure compensation amount can be obtained by pre-testing the relationship between the average speed and the wind pressure compensation amount, and the corresponding wind pressure compensation amount can be obtained according to the target average speed through this relationship. In some further specific embodiments, the smart device obtains the wind pressure compensation amount by requesting feedback from a remote server. Specifically: the smart device enters the Internet where the control server is located, and sends the target average speed to the control server through the Internet. After the control server receives the target average speed sent by the smart device, since the control server has stored a speed-wind pressure comparison table in its storage unit in advance. The control server can query the speed-wind pressure comparison table according to the target average speed by looking up the table to obtain the corresponding wind pressure compensation amount. Since the control server is already connected to the smart device through the Internet, the control server can feed back the obtained wind pressure compensation amount to the smart device through the Internet.

[0034] Step 3: Obtain the weather conditions at the current location of the target tunnel, and record the weather conditions as the target weather conditions.

[0035] The wind pressure of the target tunnel in the target direction is determined by the local climate conditions. Therefore, it is necessary to understand the current weather conditions of the target tunnel. The smart device can access the weather forecast server to determine the weather conditions at the current location of the target tunnel. For the convenience of description, the weather conditions are recorded as target weather conditions.

[0036] Step 4: Obtain a recommended wind pressure value according to the target weather condition.

[0037] After obtaining the target weather conditions, the smart device can obtain the recommended wind pressure value according to the target weather conditions. The recommended wind pressure value is pre-tested, and is the wind pressure value of each observation point of the corresponding target tunnel under the corresponding weather conditions when the target tunnel meets the specified ventilation requirements. Among them, a wind pressure recommendation comparison table is formed by combining different weather conditions with corresponding wind pressures, and the wind pressure recommendation comparison table is stored in advance. In some further specific embodiments, the wind pressure recommendation comparison table is stored in the local device of the smart device. The smart device can obtain the recommended wind pressure value corresponding to the target weather condition by using a table lookup method in the local device.

[0038] Of course, in some further specific embodiments, the recommended wind pressure comparison table is stored in the control server. The smart device can obtain the recommended wind pressure value by requesting feedback from the control server. Specifically, the smart device enters the Internet where the control server is located, and sends the target weather condition to the control server through the Internet. After the control server receives the target weather condition sent by the smart device, since the control server has stored the recommended wind pressure comparison table in its storage unit in advance. The control server can query the corresponding recommended wind pressure value from the recommended wind pressure comparison table according to the target weather condition by looking up the table. Since the control server is already connected to the smart device through the Internet, the control server can feed back the obtained recommended wind pressure value to the smart device through the Internet.

[0039] Step 5: Subtract the wind pressure recommended value from the wind pressure compensation amount to obtain a target wind pressure value.

[0040] Through research, it is found that in the target direction, the traffic will have a positive impact on the wind pressure in the target tunnel. When the average speed of the traffic is higher, the wind speed in the target tunnel in the target direction is higher. Therefore, in order to truly reflect the wind pressure value required by the target tunnel in the target direction. The smart device will subtract the wind pressure recommended value from the wind pressure compensation amount to obtain the target wind pressure value. The target wind pressure value can be considered as the value that needs to be additionally increased in the target direction of the target tunnel.

[0041] Step 6: Control the power of ventilation equipment at each observation point sequentially arranged along the target direction of the target tunnel so that the wind pressure value at each observation point is the target wind pressure value.

[0042] After determining that the target wind pressure value has been calculated, the intelligent device will establish a communication link with the ventilation equipment at each observation point in the target direction of the target tunnel. The ventilation equipment is controlled through the communication link. By controlling the power of the ventilation equipment, the wind pressure value at each observation point reaches the target wind pressure value. In this way, intelligent control of the ventilation equipment on the target tunnel is realized.

[0043] The present invention pays attention to the average speed of the traffic in the target direction on the target tunnel, and considers the influence of the average speed on the wind pressure in the target tunnel, thereby determining the wind pressure compensation amount according to the influence. The wind pressure on the target tunnel is calculated using the wind pressure compensation amount to obtain the optimal target wind pressure value. Finally, the power of the ventilation equipment of the target tunnel is controlled according to the target wind pressure value. Intelligent control of the ventilation equipment of the target tunnel is achieved, saving resources.

[0044] In some further specific embodiments, the tunnel ventilation equipment monitoring method further includes: obtaining the traffic density of the target tunnel in the target direction, the traffic density being recorded as the target density; obtaining a correction coefficient of the recommended wind pressure value according to the target density, and correcting the recommended wind pressure value by the correction coefficient. When the traffic density in the target tunnel is high, it is considered that the density of people in the target tunnel is high. In order to ensure the breathing of people, a higher wind pressure is required to ensure good ventilation. However, when the traffic density in the target tunnel is low, it is considered that the density of people in the target tunnel is not high. In order to save resources and ensure the effective breathing of people, a higher wind pressure may not be required. Therefore, when considering the recommended wind pressure value, in addition to considering weather conditions, the traffic density also needs to be considered. Therefore, the traffic density can be used as a correction amount to correct the obtained recommended wind pressure value.

[0045] Second, refer to Figure 2 , Figure 2 It is a schematic diagram of the device structure of the tunnel ventilation equipment monitoring device.

[0046] A tunnel ventilation equipment monitoring device is provided, comprising: a processor and a memory, wherein the memory is used to store a computer-readable program. When the computer-readable program is executed by the processor, the processor implements the tunnel ventilation equipment monitoring method as described in any one of the above technical solutions.

[0047] It will be appreciated by those skilled in the art that all or some of the steps and systems in the methods disclosed above may be implemented as software, firmware, hardware, and appropriate combinations thereof. Some or all physical components may be implemented as software executed by a processor, such as a central processing unit, a digital signal processor, or a microprocessor, or as hardware, or as an integrated circuit, such as an application-specific integrated circuit. Such software may be distributed on a computer-readable medium, which may include a computer storage medium (or non-transitory medium) and a communication medium (or transient medium). As known to those skilled in the art, the term computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information (such as computer-readable instructions, data structures, program modules, or other data). Computer storage media include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tapes, disk storage or other magnetic storage devices, or any other medium that can be used to store desired information and can be accessed by a computer. As is well known to those skilled in the art, communication media typically embodies computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism, and may include any information delivery media.

[0048] Thirdly, reference Figure 3 , Figure 3 It is a schematic diagram of the system connection structure of the tunnel ventilation equipment monitoring system.

[0049] A tunnel ventilation equipment monitoring system is provided, comprising: a first acquisition module, a determination module, a second acquisition module, a third acquisition module, a calculation module and a control module.

[0050] The first acquisition module is used to acquire an average speed of the vehicle flow in the target tunnel in the target direction, and record the average speed as the target average speed.

[0051] For the target tunnel, it generally has one direction or two directions depending on the design of the road. That is, the traffic generally flows from one end of the target tunnel to the other end; or, the traffic flows from the other end of the target tunnel to one end. For the ventilation design of the target tunnel, the ventilation design in one direction is generally considered. Moreover, the ventilation design in this direction is consistent with the direction of the current traffic. Therefore, in this specific embodiment, a single direction is considered. For the convenience of description, the direction to be studied in this specific embodiment is recorded as the target direction.

[0052] Since the traffic management system monitors the average speed of the traffic in the target direction of the target tunnel in real time, the first acquisition module only needs to obtain the average speed of the traffic in the target direction of the target tunnel from the traffic management system through the Internet. For ease of description, the obtained average speed of the traffic is recorded as the target average speed.

[0053] The determination module is used to determine the wind pressure compensation amount according to the target average speed.

[0054] As the traffic moves in the target tunnel, its average speed will affect the wind pressure in the target tunnel. Through research, it is found that in the target direction, the traffic will have a positive impact on the wind pressure in the target tunnel. When the average speed of the traffic is greater, the wind speed in the target tunnel in the target direction is greater. Therefore, when considering the wind pressure of the target tunnel in the target direction, it is necessary to consider the impact of the target average speed. This impact is reflected by the wind pressure compensation amount.

[0055] The wind pressure compensation amount can be obtained by preliminary testing to obtain the relationship between the average speed and the wind pressure compensation amount, and the corresponding wind pressure compensation amount can be obtained according to the target average speed through this relationship. In some further specific embodiments, the determination module obtains the wind pressure compensation amount by requesting feedback from a remote server. Specifically: the determination module enters the Internet where the control server is located, and sends the target average speed to the control server through the Internet. After the control server receives the target average speed sent by the smart device, since the control server has stored a speed-wind pressure comparison table in its storage unit in advance. The control server can query the speed-wind pressure comparison table according to the target average speed by looking up the table to obtain the corresponding wind pressure compensation amount. Since the control server is already connected to the smart device through the Internet, the control server can feed back the obtained wind pressure compensation amount to the determination module through the Internet.

[0056] The second acquisition module is used to acquire the weather condition at the current location of the target tunnel, and record the weather condition as the target weather condition.

[0057] The wind pressure of the target tunnel in the target direction is determined by the local climate conditions. Therefore, it is necessary to understand the current weather conditions of the target tunnel. The second acquisition module can access the weather forecast server to determine the weather conditions at the current location of the target tunnel through the weather forecast server. For the convenience of description, the weather conditions are recorded as target weather conditions.

[0058] The third acquisition module is used to acquire the recommended wind pressure value according to the target weather condition.

[0059] After obtaining the target weather conditions, the third acquisition module can obtain the recommended wind pressure value according to the target weather conditions. The recommended wind pressure value is pre-tested, and is the wind pressure value of each observation point of the corresponding target tunnel under the corresponding weather conditions when the target tunnel meets the specified ventilation requirements. Among them, a wind pressure recommendation comparison table is formed with different weather conditions and corresponding wind pressures, and the wind pressure recommendation comparison table is stored in advance. In some further specific embodiments, the wind pressure recommendation comparison table is stored in the local device of the third acquisition module. The third acquisition module can obtain the recommended wind pressure value corresponding to the target weather condition by using a table lookup method on the local device.

[0060] Of course, in some further specific embodiments, the recommended wind pressure comparison table is stored in the control server. The third acquisition module can obtain the recommended wind pressure value by requesting feedback from the control server. Specifically, the third acquisition module enters the Internet where the control server is located, and sends the target weather condition to the control server through the Internet. After the control server receives the target weather condition sent by the third acquisition module, since the control server has stored the recommended wind pressure comparison table in its storage unit in advance. The control server can query the corresponding recommended wind pressure value from the recommended wind pressure comparison table according to the target weather condition by looking up the table. Since the control server is already connected to the third acquisition module through the Internet, the control server can feed back the obtained recommended wind pressure value to the third acquisition module through the Internet.

[0061] The calculation module is used to subtract the wind pressure recommended value from the wind pressure compensation amount to obtain a target wind pressure value.

[0062] Through research, it is found that in the target direction, the traffic will have a positive impact on the wind pressure in the target tunnel. When the average speed of the traffic is higher, the wind speed of the target tunnel in the target direction is higher. Therefore, in order to truly reflect the wind pressure value required by the target tunnel in the target direction. The calculation module will subtract the wind pressure recommended value from the wind pressure compensation amount to obtain the target wind pressure value. The target wind pressure value can be considered as the value that needs to be additionally increased in the target direction of the target tunnel.

[0063] The control module is used to control the power of ventilation equipment at various observation points arranged in sequence along the target direction of the target tunnel, so that the wind pressure value at each observation point is the target wind pressure value.

[0064] After determining that the target wind pressure value has been calculated, the control module will establish a communication link with the ventilation equipment at each observation point in the target direction of the target tunnel. The ventilation equipment is controlled through the communication link. The wind pressure value at each observation point reaches the target wind pressure value by controlling the power of the ventilation equipment. Thus, intelligent control of the ventilation equipment on the target tunnel is realized.
