[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application 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 application and are not used to limit the present application.

[0027] The cable tunnel control method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the acquisition terminal 102 is in communication connection with the control device 104 .

[0028] The control device 104 can obtain the ambient light intensity at the tunnel entrance of the cable tunnel and the respective device installation positions of multiple tunnel lighting devices set in the cable tunnel from the acquisition terminal 102. The control device 104 can determine the expected lighting intensity of the tunnel lighting device for each tunnel lighting device based on the device installation position of the tunnel lighting device and the ambient light intensity, wherein the distance between the device installation position and the tunnel entrance position is positively correlated with the difference between the ambient light intensity and the expected lighting intensity; the ambient light intensity is greater than the expected lighting intensity. The control device 104 can control the tunnel lighting device to illuminate according to the expected lighting intensity corresponding to the tunnel lighting device.

[0029] The acquisition terminal 102 may be, but is not limited to, a terminal with information acquisition capability, such as a gas sensor, a temperature sensor, a humidity sensor, a light sensor, etc. The control device 104 may be a device with data processing capability, such as a single chip microcomputer.

[0030] In one embodiment, Figure 2 As shown, a cable tunnel control method is provided, which is applied to Figure 1 The control device 104 in FIG. 1 is used as an example to illustrate, including:

[0031] S202, obtaining the ambient light intensity at the tunnel entrance of the cable tunnel and the respective device installation positions of a plurality of tunnel lighting devices arranged in the cable tunnel.

[0032] Among them, a cable tunnel is a narrow corridor or tunnel-like structure used to accommodate a large number of cables. The main function is to protect the cables from the influence of the external environment. Specifically, in order to facilitate the maintenance personnel to install, inspect and repair the cables in the cable tunnel, in addition to the cables that need to be laid, the cable tunnel also has installation, inspection and maintenance channels, such as inspection and patrol trails. Maintenance personnel can perform corresponding installation, inspection and maintenance work on the inspection and patrol trails according to task requirements.

[0033] The tunnel entrance location can represent the location of the entrance and exit of the cable tunnel. For example, the tunnel entrance location can be represented by geographic coordinates. The tunnel entrance location can also be the location of the connecting hole in the cable tunnel that is connected to the outside world.

[0034] The ambient light intensity may represent the light intensity corresponding to the tunnel entrance position, for example, the light intensity at the tunnel entrance position, the light intensity at the tunnel exit position, and the light intensity at the tunnel connecting hole position.

[0035] Tunnel lighting equipment can be equipment that plays a lighting role in cable tunnels. Tunnel lighting equipment can include entrance lights, internal lights and exit lights. The entrance light is located at the entrance of the tunnel, providing soft yellow or white light to help maintenance personnel adapt to the light environment in the tunnel; the internal light is installed inside the tunnel to provide evenly distributed lighting; the exit light is located at the exit of the tunnel, using red or red and green combination lights to guide maintenance personnel to exit the tunnel safely.

[0036] The device installation location may indicate the installation location of the tunnel lighting device in the cable tunnel. For example, the installation location of the entrance light may be the top of the inner wall of the tunnel entrance. For another example, the installation location of the interior light may be the side wall or the ground in the middle of the control tunnel.

[0037] It should be noted that the installation position of lighting equipment should take into account the uniformity of light and avoidance of sight obstruction. Generally, lighting equipment should be installed on the top of the tunnel to provide the best lighting effect. In addition, the layout of lamps can be in the form of center line, center line side deviation, staggered on both sides, and symmetrical on both sides. When making specific arrangements, it is also necessary to consider the geometry of the tunnel, maintenance requirements, and potential collisions with other equipment (such as tunnel fans).

[0038] Specifically, the control device may obtain the ambient light intensity at the tunnel entrance of the cable tunnel and the respective device installation positions of a plurality of tunnel lighting devices arranged in the cable tunnel from the acquisition terminal.

[0039] In one embodiment, the control device may directly acquire the device installation positions of each of the plurality of tunnel lighting devices arranged in the cable tunnel.

[0040] S204: for each tunnel lighting device, based on the device installation position of the tunnel lighting device and the ambient light intensity, determine the expected lighting intensity of the tunnel lighting device.

[0041] The expected lighting intensity may represent the light intensity output by the tunnel lighting device. The expected lighting intensity may be positively correlated with the expected output power of the tunnel lighting device. The greater the expected lighting intensity, the greater the expected output power.

[0042] The expected lighting intensity may be an expected value of light intensity for people or equipment. The expected lighting intensity may be different according to different application scenarios and requirements. For example, the difference between the expected lighting intensity and the ambient light intensity at the entrance of a tunnel is small, and the difference between the expected lighting intensity and the ambient light intensity at the exit of a tunnel is small.

[0043] Among them, the distance between the equipment installation location and the tunnel entrance is positively correlated with the difference between the ambient light intensity and the expected lighting intensity, and the ambient light intensity is greater than the expected lighting intensity.

[0044] The distance between the equipment installation position and the tunnel entrance position can represent the distance between the tunnel lighting equipment and the tunnel entrance, tunnel exit or tunnel connecting opening. It can be understood that the distance between the tunnel lighting equipment and the nearest tunnel entrance can be determined as the distance between the equipment installation position and the tunnel entrance position.

[0045] The difference between the ambient light intensity and the desired lighting intensity, and the ambient light intensity is greater than the desired lighting intensity. It can be understood that the closer the tunnel lighting equipment is to the tunnel entrance, the closer the corresponding desired lighting intensity is to the ambient light intensity. The farther the tunnel lighting equipment is from the tunnel entrance, the farther the corresponding desired lighting intensity is from the ambient light intensity.

[0046] Specifically, for each tunnel lighting device, the control device may determine the expected lighting intensity of the tunnel lighting device based on the device installation position of the tunnel lighting device and the ambient light intensity.

[0047] In one embodiment, the control device can also obtain the real-time light intensity of each position in the control tunnel through the acquisition terminal. The control device adjusts each expected light intensity according to each real-time light intensity to obtain the adjusted light intensity corresponding to each expected light intensity.

[0048] In one of the embodiments, the control device may control the tunnel lighting device to perform lighting according to the light intensity adjusted accordingly by the tunnel lighting device.

[0049] S206: Control the tunnel lighting device to perform lighting according to the expected lighting intensity corresponding to the tunnel lighting device.

[0050] When maintenance personnel enter or exit a cable tunnel or enter a cable tunnel with a transport device, they will suddenly enter a darker environment from a bright environment due to the brightness difference between the inside and outside of the cable tunnel. At this time, the human eye needs time to adapt to this brightness change, which usually takes a few seconds to more than ten seconds. During this process, maintenance personnel may experience blurred vision or even temporary loss of vision, a phenomenon known as the "black hole effect." The black hole effect can make it difficult for maintenance personnel to identify the situation near the tunnel entrance, thereby increasing the risk of traffic accidents.

[0051] On the contrary, when the maintenance personnel leave the cable tunnel, they will feel strong glare and their pupils will shrink rapidly due to the sudden entry from the dark into the bright environment, which makes it impossible to see the situation outside the tunnel immediately. This phenomenon is called the "white hole effect". The white hole effect will also reduce the visual function of the maintenance personnel and easily increase the risk of collision. It is understandable that maintenance personnel can take a transport device to perform maintenance tasks (cable installation, cable inspection, cable repair, etc.). The transport device can be a device equipped with a visual recognition camera. Similarly, the transport device can also perform maintenance tasks alone. The recognition accuracy of the visual recognition device of the transport device affects the accuracy and efficiency of the task execution. The transport device will also experience the "white hole effect" and "black hole effect" when entering and exiting the cable tunnel. The strong change of light intensity in a short time will affect the accuracy and efficiency of the visual recognition device.

[0052] Specifically, the control device can control the tunnel lighting device to illuminate according to the desired lighting intensity corresponding to the tunnel lighting device. On the one hand, the closer the tunnel lighting device is to the tunnel entrance, the closer the corresponding desired lighting intensity is to the ambient light intensity. The farther the tunnel lighting device is from the tunnel entrance, the farther the corresponding desired lighting intensity is from the ambient light intensity. This avoids the "black hole effect" and "white hole effect" and improves safety. On the other hand, there is no need to control the lighting intensity of all lighting devices to be consistent with the ambient light intensity, saving electricity costs and lighting costs.

[0053] In the above-mentioned cable tunnel control method, the ambient light intensity at the tunnel entrance of the cable tunnel and the respective equipment installation positions of multiple tunnel lighting devices arranged in the cable tunnel are obtained. For each tunnel lighting device, the expected lighting intensity of the tunnel lighting device is determined based on the equipment installation position of the tunnel lighting device and the ambient light intensity, wherein the distance between the equipment installation position and the tunnel entrance is positively correlated with the difference between the ambient light intensity and the expected lighting intensity, and the ambient light intensity is greater than the expected lighting intensity. By using the above-mentioned method, the closer the expected lighting intensity is to the tunnel entrance, the closer it is to the ambient light intensity. According to the expected lighting intensity corresponding to the tunnel lighting device, the tunnel lighting device is controlled to perform lighting, so that each tunnel lighting device in the tunnel does not need to output at full power, thus saving output power and thereby reducing lighting costs.

[0054] In one embodiment, the cable tunnel control method further includes: obtaining gas concentrations corresponding to multiple target gases at different tunnel positions in the cable tunnel, and for each target gas, when any gas concentration corresponding to the target gas is greater than a gas concentration threshold of the target gas, controlling the tunnel ventilation equipment in the cable tunnel to start.

[0055] The target gas may be a gas that is harmful to people or equipment, such as carbon monoxide, carbon dioxide, etc.

[0056] Gas concentration can indicate the content of target gas in the air.

[0057] The gas concentration threshold may be a concentration threshold set for the target gas, for example, a carbon monoxide concentration threshold is set for carbon monoxide, and a carbon dioxide concentration threshold is set for carbon dioxide.

[0058] The tunnel ventilation equipment may be equipment with ventilation function. Specifically, the tunnel ventilation equipment may be equipment with the ability to exchange air inside and outside the tunnel. For example, TVF (Tunnel Ventilation Fan) fans and jet fans.

[0059] TVF fans have the characteristics of large air volume and high pressure, which can effectively discharge the hot air and polluted gas inside the tunnel and ensure the air quality of the tunnel. Jet fans can generate thrust by ejecting high-speed airflow, thereby enhancing the air flow in the tunnel and improving ventilation efficiency. This fan has many advantages. Jet fans can generate large thrust when working, which is suitable for occasions that require strong wind and long-distance transmission.

[0060] There are many ways to obtain gas concentration. For example, the control device can use a carbon monoxide analyzer to utilize the selective absorption characteristics of carbon monoxide to infrared light of a specific wavelength to determine the concentration of carbon monoxide by measuring the absorption value. The control device can also measure the concentration of carbon monoxide by detecting changes in semiconductor resistance. For example, the control device can separate carbon monoxide and carbon dioxide through a chromatographic column, enter a converter for reaction, and then measure it with a hydrogen flame ionization detector. The control device can also use the absorption characteristics of carbon dioxide to light of a specific wavelength to determine the concentration of carbon dioxide by measuring the absorption value.

[0061] For example, the control device may directly measure the gas concentration via a carbon monoxide sensor and a carbon dioxide sensor.

[0062] In this embodiment, the gas concentrations corresponding to multiple target gases at different tunnel positions in the cable tunnel are obtained. For each target gas, when any gas concentration corresponding to the target gas is greater than the gas concentration threshold of the target gas, the tunnel ventilation equipment in the cable tunnel is controlled to start, thereby reducing the target gas concentration in the cable tunnel and improving the environmental safety of the cable tunnel.

[0063] In one embodiment, the cable tunnel control method further includes: acquiring tunnel temperatures collected in different tunnel areas of the cable tunnel, and controlling the tunnel ventilation equipment to start when any tunnel temperature is greater than a temperature threshold.

[0064] The tunnel temperature may represent the average temperature of the tunnel area.

[0065] The temperature threshold may be a threshold configured for each tunnel temperature.

[0066] There are many ways to measure tunnel temperature. Specifically, the control equipment uses optical fiber sensors to achieve real-time monitoring of the temperature inside the tunnel through Raman scattering and optical time domain reflectometry (OTDR) technology, and obtains the tunnel temperature collected in different tunnel areas of the tunnel.

[0067] The control equipment can also integrate functions such as cable temperature monitoring and environmental monitoring. By laying an optical fiber temperature measurement subsystem in the tunnel, the temperature of different tunnel areas of the cable tunnel can be obtained.

[0068] For example, for each tunnel area of ​​the cable tunnel, multiple temperature sensors are pre-arranged in the tunnel area. The control device can obtain the measured temperatures of each of the multiple temperature sensors. The control device can average the multiple measured temperatures to obtain the tunnel temperature of the tunnel area.

[0069] In one embodiment, the control device performs abnormal value screening on each measured temperature, screens out abnormal temperature values ​​and outliers, and obtains screened measured temperatures. The control device averages multiple screened measured temperatures to obtain the tunnel temperature of the tunnel area.

[0070] In this embodiment, the tunnel temperatures collected in different tunnel areas of the cable tunnel are obtained. When the temperature of any tunnel is greater than the temperature threshold, the tunnel ventilation equipment is controlled to start, so as to avoid excessive temperature in the cable tunnel, which may cause adverse effects on people and equipment, and improve the safety of the tunnel environment.

[0071] In one embodiment, the cable tunnel control method also includes: obtaining multiple preset alarm modes of the sound and light alarm, each preset alarm mode corresponds to a different preset score; for each target gas, among the gas concentrations corresponding to the target gas, screening a target concentration greater than a gas concentration threshold of the target gas; among the tunnel temperatures, screening a target temperature greater than a temperature threshold; determining an environmental score based on the number corresponding to the target concentration and the number corresponding to the target temperature; among each preset alarm mode, determining a target alarm mode corresponding to a preset score closest to the environmental score; and controlling the sound and light alarm to perform sound and light alarms in the target alarm mode.

[0072] Among them, the sound and light alarm can be a device that combines sound and light warning functions. The device is mainly composed of a sound generator and a light signal lamp. When the system detects an abnormal state (such as smoke, fire, gas leakage or equipment failure), the sound and light alarm will issue a harsh alarm sound and flashing lights to remind personnel to take timely measures.

[0073] The preset alarm mode can indicate the severity of the alarm of the sound and light alarm. For example, the preset alarm mode can be a sound alarm mode only, a light source alarm mode only, or a sound and light combined alarm mode. Furthermore, the sound alarm mode includes a low decibel alarm sub-mode and a high decibel alarm sub-mode. The light source alarm mode includes a light source flashing frequency, a light source illumination intensity, a light source color, etc.

[0074] The preset score corresponding to the preset alarm mode can indicate the severity of the alarm mode. For example, the preset score of the sound alarm mode is less than the preset score of the light alarm mode, and the preset score of the light alarm mode is less than the preset score of the sound and light combined alarm mode. Specifically, the preset score of the low decibel alarm sub-mode is less than the preset score of the high decibel alarm sub-mode.

[0075] The target temperature may represent a tunnel temperature greater than a temperature threshold. The target concentration may represent a gas concentration greater than a gas concentration threshold of the target gas. Both the target concentration and the gas concentration are concentrations corresponding to the target gas.

[0076] The environmental score may be a score that characterizes the expected severity of the alarm. A higher environmental score may indicate a greater number of target concentrations and / or a greater number of target temperatures.

[0077] The target alarm mode may be a preset alarm mode corresponding to a preset score closest to the environment score.

[0078] Specifically, the control device can control the sound and light alarm to perform sound and light alarm in a target alarm mode. Since the target alarm mode reflects the score of the expected alarm severity, it takes into account both improving the accuracy of the sound and light alarm and reducing the cost of the sound and light alarm.

[0079] In the present embodiment, a plurality of preset alarm modes of the sound and light alarm are obtained, each preset alarm mode corresponds to a different preset score, for each target gas, among the gas concentrations corresponding to the target gas, a target concentration greater than the gas concentration threshold of the target gas is screened, and among the tunnel temperatures, a target temperature greater than the temperature threshold is screened, and the environmental score is determined based on the number corresponding to the target concentration and the number corresponding to the target temperature, and in each preset alarm mode, a target alarm mode corresponding to the preset score closest to the environmental score is determined, and the sound and light alarm is controlled to perform sound and light alarm in the target alarm mode. Since the target alarm mode reflects the score of the expected alarm severity, both improving the accuracy of the sound and light alarm and reducing the cost of the sound and light alarm are taken into account.

[0080] In one embodiment, the cable tunnel control method further includes: determining a tunnel position corresponding to a target concentration and a tunnel area corresponding to a target temperature, and sending the tunnel position and the tunnel area to a terminal held by a tunnel maintenance personnel.

[0081] The tunnel position may include the installation position of the gas sensor for collecting the target concentration. The tunnel position may also include the projection position of the gas detection range represented by the target concentration on the tunnel ground.

[0082] Likewise, the tunnel area may include the installation location of the temperature sensor for collecting the target temperature. The tunnel area may also include the projection location of the temperature monitoring range represented by the target temperature on the tunnel floor.

[0083] Specifically, the control device can send the tunnel location and tunnel area to the terminal held by the tunnel maintenance personnel, which helps the tunnel maintenance personnel to quickly and accurately reach the on-site location and start maintenance.

[0084] In one embodiment, the control device can send the installation position and projection position corresponding to the target concentration, and the installation position and projection position corresponding to the target temperature to the terminal held by the tunnel maintenance personnel. The tunnel maintenance personnel can obtain more comprehensive information, which improves maintenance efficiency and safety.

[0085] In one embodiment, the control device can plan a maintenance route for the tunnel maintenance personnel based on the installation location and projection location corresponding to the target concentration, and the installation location and projection location corresponding to the target temperature. The control device can send the installation location and projection location corresponding to the target concentration, the installation location and projection location corresponding to the target temperature, and the maintenance route to a terminal held by the tunnel maintenance personnel.

[0086] In this embodiment, the tunnel position corresponding to the target concentration and the tunnel area corresponding to the target temperature are determined, and the tunnel position and the tunnel area are sent to a terminal held by the tunnel maintenance personnel, which helps to improve maintenance efficiency and safety.

[0087] In one embodiment, the cable tunnel control method also includes: obtaining a traffic score characterizing the real-time traffic of the cable tunnel, the real-time traffic being positively correlated with the traffic score; determining an expected operating frequency of the tunnel ventilation equipment based on the traffic score and the environmental score; and controlling the tunnel ventilation equipment to operate at the expected operating frequency.

[0088] Among them, installation, inspection and maintenance in a cable tunnel may correspond to multiple maintenance personnel and transport devices, that is, there may be multiple maintenance personnel and multiple transport devices in the cable tunnel at the same time, and in order to ensure the safety of maintenance personnel and the identification accuracy of transport devices, and reduce the heating phenomenon of transport devices. Therefore, when there are many maintenance personnel and transport devices, the operation frequency of ventilation equipment needs to be increased.

[0089] Real-time traffic can represent the number of transport devices entering the cable tunnel per unit time.

[0090] The flow score may represent a score set for the number of real-time transport devices. The flow score is positively correlated with the real-time flow.

[0091] The environmental score can be a score reflecting the quality of air in the cable tunnel. A higher environmental score can indicate worse air quality in the cable tunnel (higher PM2.5 concentration), more harmful gases (higher carbon monoxide and / or carbon dioxide concentration), and higher temperature. And vice versa.

[0092] The expected operating frequency may represent the expected start and stop frequency of the tunnel ventilation equipment.

[0093] Specifically, the control device may determine the expected operating frequency of the tunnel ventilation device based on the flow score and the environment score, and may control the tunnel ventilation device to operate at the expected operating frequency.

[0094] In one embodiment, the control device may obtain the score weights of the flow score and the environment score. The control device may obtain a total score based on the flow score, the environment score, and the score weights of the flow score and the environment score. The control device determines the expected operating frequency of the tunnel ventilation device based on the total score. The total score is positively correlated with the expected operating frequency.

[0095] In this embodiment, a traffic score characterizing the real-time traffic in the cable tunnel is obtained, and the real-time traffic is positively correlated with the traffic score. Based on the traffic score and the environmental score, the expected operating frequency of the tunnel ventilation equipment is determined, and the tunnel ventilation equipment is controlled to operate at the expected operating frequency, taking into account both ventilation efficiency and ventilation cost.

[0096] In one embodiment, Figure 3 As shown, a cable tunnel control system is provided, the system includes an ambient light intensity detection device 310, a control device 320, and a plurality of tunnel lighting devices 330;

[0097] The ambient light intensity detection device 310 is used to detect the ambient light intensity at the tunnel entrance of the cable tunnel.

[0098] Among them, the ambient light intensity monitoring device can be a light sensor.

[0099] The control device 320 is used to obtain the ambient light intensity and the device installation position of each tunnel lighting device 330. For each tunnel lighting device 330, based on the device installation position of the tunnel lighting device 330 and the ambient light intensity, the expected lighting intensity of the tunnel lighting device 330 is determined, and the tunnel lighting device 330 is controlled to perform lighting according to the expected lighting intensity corresponding to the tunnel lighting device 330.

[0100] Among them, the distance between the equipment installation location and the tunnel entrance is positively correlated with the difference between the ambient light intensity and the expected lighting intensity, and the ambient light intensity is greater than the expected lighting intensity.

[0101] The control device 320 may be a single chip microcomputer.

[0102] The tunnel lighting control device 330 may be an LED lamp, and appropriate lighting intensity is set in different sections of the cable tunnel to achieve the purpose of energy saving and environmental protection.

[0103] In this embodiment, the system includes an ambient light intensity detection device, a control device, and a plurality of tunnel lighting devices. The ambient light intensity detection device is used to detect the ambient light intensity at the tunnel entrance of the cable tunnel. The control device is used to obtain the ambient light intensity and the device installation position of each tunnel lighting device. For each tunnel lighting device, based on the device installation position of the tunnel lighting device and the ambient light intensity, the desired lighting intensity of the tunnel lighting device is determined. According to the desired lighting intensity corresponding to the tunnel lighting device, the tunnel lighting device is controlled to perform lighting. The distance between the device installation position and the tunnel entrance is positively correlated with the difference between the ambient light intensity and the desired lighting intensity, and the ambient light intensity is greater than the desired lighting intensity. The closer the desired lighting intensity is to the tunnel entrance, the closer it is to the ambient light intensity. According to the desired lighting intensity corresponding to the tunnel lighting device, the tunnel lighting device is controlled to perform lighting, so that each tunnel lighting device in the cable tunnel does not need to output at full power, which saves output power and reduces lighting costs.

[0110] S401, obtaining the ambient light intensity at the tunnel entrance of the cable tunnel and the respective device installation positions of a plurality of tunnel lighting devices arranged in the cable tunnel.

[0111] The control device may be an STM32 single-chip microcomputer. The STM32 single-chip microcomputer may be connected to a temperature and humidity sensor, a light intensity sensor, a carbon dioxide concentration sensor, a carbon monoxide concentration sensor, and a liquid crystal display module. Figure 5 The system flow chart shown in the figure realizes the function of using multiple sensors to collect and display real-time data of various environmental parameters in the control tunnel, and analyzes and processes the data through the control system, and compares it with the safety factor. If it is within the safety factor range, it continues to work normally. Otherwise, it performs pre-alarm processing and notifies the staff to troubleshoot the problem.

[0112] Among them, STM32F103 has 64KB flash memory for storing program code and 20KB SRAM for runtime data storage. The chip has a main frequency of 72MHz and a fast execution speed. The chip also provides a variety of options in terms of communication interface, including USART interface, SPI and I2C interface. It supports multiple timers, which enhances the flexibility of system control. In terms of power management, the chip supports multiple energy-saving modes, allowing developers to adjust power consumption according to application requirements.

[0113] The DHT11 temperature and humidity sensor is used to collect temperature and humidity data in the control tunnel. The temperature and humidity data can be collected and directly output as digital signals through DHT11, and the DHT protocol is used for data transmission. The collected data is transmitted to the main control chip through 3 pins.

[0114] In the circuit design, the VCC, GND and DATA pins of the sensor are connected to the VCC, GND and PB13 pins of the main control chip respectively. The NC pin needs to be left floating so that the output temperature and humidity data can be stable.

[0115] The light sensor can collect analog values ​​of light intensity. The external pins of this module are mainly composed of VCC, GND, AO analog output pin, and DO digital output pin. In the circuit design, the channels of STM32F103 are used as acquisition channels, that is, the AO pin is connected to PA1 of the microcontroller, DO is set to be floating, and powered by 3.3V voltage.

[0117] The MQ-7 carbon monoxide concentration sensor is used to collect data on the carbon dioxide concentration in the control tunnel. Its working principle is based on the resistance change of the semiconductor gas sensor. When the combustible gas enters the sensor, it will react chemically with the sensitive material on the surface of the gas sensor, causing the resistance value to change. By measuring the change in resistance value, the size of the carbon monoxide concentration can be inferred.

[0118] The display screen can be a 0.96-inch OLED display screen to display key environmental data such as light intensity, temperature and humidity, and carbon dioxide concentration. This OLED screen adopts the I2C communication protocol and uses the standard I2C interface for communication. Its circuit connection includes the power supply terminal VCC, the ground terminal GND, the clock signal line SCL and the data line SDA. The clock synchronization mechanism is used to ensure accurate reception and instant display of instructions.

[0119] S402: For each tunnel lighting device, based on the device installation position of the tunnel lighting device and the ambient light intensity, determine the expected lighting intensity of the tunnel lighting device.

[0120] Among them, the distance between the equipment installation location and the tunnel entrance is positively correlated with the difference between the ambient light intensity and the expected lighting intensity. The ambient light intensity is greater than the expected lighting intensity.

[0121] Tunnel lighting equipment can improve the air quality in the tunnel, protect the health and safety of personnel, and improve operational efficiency. The driving module of the transport device in the tunnel consumes oxygen during operation, produces various harmful gases and increases the temperature. Excessive concentration of harmful gases will reduce visibility in the tunnel, so various sensors are used to monitor the air environment in the tunnel (such as temperature, humidity, concentration of harmful gases, etc.), and adjust the operating status of the ventilator according to the monitoring results to ensure ventilation effect.

[0122] S403: Control the tunnel lighting device to perform lighting according to the desired lighting intensity corresponding to the tunnel lighting device.

[0125] S406, obtaining tunnel temperatures collected respectively in different tunnel areas of the cable tunnel.

[0126] S407: When the temperature of any tunnel is greater than the temperature threshold, control the tunnel ventilation equipment to start.

[0127] Among them, for tunnel ventilation equipment, by optimizing the airflow design, a higher energy conversion efficiency can be achieved, thereby reducing energy consumption. Moreover, compared with traditional fans, jet fans produce less noise during operation and are suitable for use in semi-enclosed environments such as tunnels. In addition, jet fans are relatively easy to install and can usually be hung on the top or sides of the tunnel, without occupying building area or requiring the construction of additional air ducts.

[0128] The early warning and emergency response system uses an audio-visual alarm module that combines LED lights and buzzers to remind transportation equipment passing through the tunnel to pay attention to safety and notify staff to eliminate problems in a timely manner.

[0129] S408, obtaining multiple preset alarm modes of the sound and light alarm, each preset alarm mode corresponding to a different preset score.

[0130] S409, for each target gas, select a target concentration greater than a gas concentration threshold of the target gas from among various gas concentrations corresponding to the target gas.

[0131] S410, selecting a target temperature greater than a temperature threshold among the temperatures of each tunnel.

[0132] S411, determining an environmental score based on the number corresponding to the target concentration and the number corresponding to the target temperature.

[0133] S412: Determine, among the preset alarm modes, a target alarm mode corresponding to a preset score closest to the environment score.

[0134] S413, controlling the sound and light alarm to make sound and light alarm in the target alarm mode.

[0135] S414, determining the tunnel position corresponding to the target concentration and the tunnel area corresponding to the target temperature.

[0136] S415, sending the tunnel location and tunnel area to a terminal held by a tunnel maintenance personnel.

[0137] S416, obtaining a traffic score representing the real-time traffic of the cable tunnel, where the real-time traffic is positively correlated with the traffic score.

[0138] S417, determining the expected operating frequency of the tunnel ventilation equipment based on the flow score and the environment score.

[0139] S418, controlling the tunnel ventilation equipment to operate at a desired operating frequency.

[0140] This method can be applied to the control system. The control system is part of the tunnel environment monitoring and safety assurance system. The detailed workflow of the tunnel environment monitoring and safety assurance system is as follows:

[0141] 1. Environmental parameter monitoring and collection

[0142] First, the environmental parameter monitoring system uses a variety of high-precision sensors to conduct comprehensive and real-time monitoring of the internal environment of the tunnel. The sensors used include but are not limited to: Temperature and humidity sensors: used to monitor the temperature and humidity changes in the tunnel in real time to ensure that the environment is in a suitable state. Light sensors: measure the light intensity inside and outside the tunnel, monitor the efficiency of the lighting system and the visibility in the tunnel. Gas sensors: monitor the air quality in the tunnel, especially the concentration of harmful gases such as carbon monoxide (CO) and carbon dioxide (CO2), to ensure that the air in the tunnel meets safety standards.

[0143] The data collected by these sensors are transmitted to the control system in real time through wireless transmission modules (such as LoRa or NB-IoT). In the control center, the system displays real-time data of various environmental parameters through the built-in OLED display, which makes it easy for operators to quickly understand the conditions inside the tunnel.

[0144] 2. Data Processing and Analysis

[0145] After the data is transmitted to the control system, the system core uses a high-performance STM32 microcontroller to process the collected data. The STM32 microcontroller judges the environmental parameters based on the preset safety thresholds, including: Safety range judgment: The system compares the real-time monitored temperature and humidity, light intensity, and carbon monoxide and carbon dioxide concentrations with safety standards. If all parameters are within the safety range, the system continues to operate normally. Abnormal situation handling: If any environmental parameter exceeds the safety threshold, the STM32 microcontroller will immediately trigger the alarm mechanism and start the early warning and emergency response system.

[0146] 3. Early warning and emergency response

[0147] After detecting abnormal environmental parameters, the system automatically enters the emergency state. The specific process is as follows: Sound and light alarm: The control system sends out warnings to the inside and outside of the tunnel through the integrated sound and light alarm device, reminding the transportation equipment in the tunnel to slow down and drive carefully. At the same time, the alarm system notifies the relevant staff to check and deal with the problem immediately to avoid accidents. Notification function: The system can transmit the alarm information to the tunnel management platform or the mobile phone APP of the relevant maintenance personnel in real time through the wireless communication module (such as 4G or Wi-Fi), realize remote alarm reminder, and ensure that the staff can take measures at the first time.

[0148] 4. Automatic control of tunnel ventilation system

[0149] When the control system detects that the concentration of carbon monoxide and carbon dioxide in the tunnel exceeds the standard, or the temperature is too high, the system will automatically start the tunnel ventilation system to quickly replace the air and cool down. The specific working principle of the ventilation system is as follows: Intelligent ventilation adjustment: The control system automatically adjusts the operation mode and wind speed of the fan based on the CO, CO2 concentration and temperature data fed back by the gas sensor to ensure that pollutants in the tunnel are quickly discharged and the temperature is reduced, ensuring that the environment in the tunnel meets safety standards and reducing the impact on the passage of transportation equipment. Energy-saving design: When the air quality in the tunnel returns to normal, the system will automatically adjust the ventilation equipment to energy-saving mode to reduce energy consumption and extend the service life of the equipment. At the same time, the start and stop frequency of the fan will be adjusted in real time according to the traffic flow and air quality in the tunnel to achieve high efficiency and energy saving.

[0150] 5. Dynamic adjustment of lighting system

[0151] In terms of the tunnel lighting system, the environmental monitoring system uses light sensors to detect the light intensity inside and outside the tunnel in real time, and dynamically adjusts the tunnel lighting brightness based on the collected data. The specific operations are as follows: Automatic dimming: When the external light is strong, the system automatically lowers the brightness of the tunnel lighting to save power consumption; when the external light is weak, the system will increase the brightness of the tunnel lighting to ensure a clear field of vision for maintenance personnel and enhance maintenance personnel. Night and bad weather adjustment: At night or in bad weather (such as haze, heavy rain), the light sensor will promptly feedback environmental changes, and the system will increase the lighting power according to the preset algorithm to ensure that the tunnel has sufficient brightness to ensure the safe passage of transportation equipment.

[0152] 6. Data storage and system self-check

[0153] In order to ensure the long-term stable operation of the system, the control system also has data storage and system self-checking functions: Data recording and analysis: The system can store the historical data of environmental parameters in the tunnel, and use big data analysis to analyze the trend of these data, predict possible equipment failures or potential safety hazards, and facilitate managers to take advance countermeasures. System self-checking function: The system will regularly self-check all subsystems to confirm whether the status of sensors, control units and actuators is normal. Once the equipment is found to be abnormal or damaged, the system will actively issue a maintenance reminder to ensure the stable operation of the system.

[0154] In this embodiment,

[0155] The above method can also bring the following beneficial effects:

[0156] (1) The control system uses the STM32F103 microcontroller, which has high performance, low power consumption, and rich peripheral interfaces. The STM32F103 has an advanced processor architecture and supports different types of memory, which makes the STM32F103 capable of various complex control tasks. It is also equipped with a wealth of debugging and development tools to help developers debug and simulate, and improve program development efficiency. In daily life, it can be used in the field of smart homes. It can be used as a controller for smart home systems to control and manage various home appliances, lighting systems, security monitoring, and energy management.

[0157] (2) The internal clock circuit of the control system is connected to the PD0OSC-IN and PD1OSC-OUT pins of the microcontroller. A simple and stable oscillation signal is sent out through a crystal oscillator with a crystal frequency of 8MHz. At the same time, a parallel resonant circuit is formed with two 25pF capacitors to ensure the normal operation of the system and the synchronization between various components. In order to maintain the long-term stable operation of the system, a reset circuit is installed in the system. When the system fails and crashes, the system can be initialized through the reset circuit. The control system uses power-on reset and is connected to the NRST pin of the microcontroller.

[0158] (3) The hardware modules of the environmental parameter monitoring system include temperature and humidity sensors, light intensity sensors, carbon dioxide concentration sensors, carbon monoxide concentration sensors and liquid crystal display modules.

When the temperature rises in the tunnel due to a traffic accident or equipment failure, the system can detect and activate the early warning system in time. The sensor has the advantages of fast response and high stability.

[0160] (5) The system uses the GY-302 BH1750 light intensity sensor module, whose main function is to convert the received light signal into an electrical signal. Its advantages are: high accuracy, capable of providing high-precision light intensity measurement and control; strong adaptability, adapting to measurement and control requirements under different lighting conditions; fast response speed, capable of quickly responding to changes in light intensity.

[0161] (6) The system uses the SPG30 carbon dioxide sensor module, which has excellent accuracy, good stability and fast response speed. The module is based on the absorption effect of carbon dioxide molecules on specific infrared light wavelengths. By emitting and detecting specific wavelength infrared light that passes through the carbon dioxide gas layer, the module can accurately quantify the carbon dioxide content based on the change in light intensity.

[0162] (7) The system uses the MQ-7 model carbon monoxide sensor. This module has high sensitivity and can detect relatively low concentrations of carbon monoxide gas, ensuring timely warning when the carbon monoxide concentration in the tunnel is too high. It has a fast response speed and can capture changes in carbon monoxide concentration in a short period of time. It also has good operating stability and can maintain high stability and reliability during long-term use.

[0163] (8) The display module of the system displays temperature and humidity data, carbon dioxide concentration and other data in real time. An OLED liquid crystal display is selected as the display module of the system. Compared with traditional LCD screens, OLED displays have greatly improved energy consumption and response speed. The 0.96-inch OLED display usually has a higher resolution and can provide clear and delicate display effects, ensuring that users can accurately display various sensor data and other information. The OLED display consumes almost no power when displaying a black background, which gives it a significant advantage in low-power applications and meets the energy-saving requirements of the system. The response speed of the OLED display is very fast, and it can complete the update of the screen within milliseconds, ensuring that the latest status information can be obtained in a timely manner. The 0.96-inch OLED display usually adopts a standard interface design, which is convenient for connection and communication with control devices such as microcontrollers.

[0164] (9) The tunnel environment monitoring and safety assurance system realizes all-round monitoring and intelligent management of the tunnel's internal environment through the combination of multiple sensors and intelligent control technologies. The system can identify potential safety hazards in the tunnel in real time and quickly initiate emergency plans, effectively reducing the risk of accidents and improving the traffic efficiency of the cable tunnel. The system's automated operation and energy-saving design provide safety assurance for the daily operation of the cable tunnel and reduce the operating costs of tunnel management.

[0165] (10) The tunnel environment monitoring and safety assurance system has many advantages such as intelligence, high efficiency, energy saving and environmental protection.
