Description

Technical Field

[0001] The invention belongs to the technical field of danger detection mining lamps, and in particular relates to an energy-saving mining lamp with a mine danger detection function. Background Art

[0002] Miner's lamps are used as lighting fixtures in mines to provide visual lighting environment for workers in mines. There are two types of miner's lamps: one is a fixed miner's lamp fixed on the wall of the mine tunnel to illuminate the entire mine tunnel, and the other is a portable miner's lamp carried by miners. Fixed miner's lamps are large in size and large in number. A fixed miner's lamp is installed at a certain distance in the mine tunnel, and the power supply is unified through the mine system. As long as there is no accident, the mine system can always provide lighting power for the fixed miner's lamp. The portable miner's lamp is worn on the waist or head of the miner, and has a separate mobile power supply. The advantage is that it can be portable, but the disadvantage is that it needs to be replenished regularly. Whether it is a traditional fixed miner's lamp or a portable miner's lamp, it can no longer meet the needs of mine production. In order to improve the safety of mine workers, the danger detection function of dangerous gases such as gas should be added to the miner's lamp facilities to achieve the purpose of protecting the lives of coal miners.

[0003] The current mining lamps, whether fixed on the walls of mine tunnels or portable carried by workers, do not have the function of monitoring hazardous gases. It is necessary to add a gas detection system in the mine to detect the gas concentration at various locations inside the mine. After a sudden danger occurs, the fixed mining lamps and portable mining lamps inside the mine cannot indicate the sudden situation and cannot assist the workers in effective evacuation.

[0004] The existing mining lamps cannot be combined with the gas detection system. At the same time, fixed mining lamps and portable mining lamps cannot provide evacuation instructions to mine workers in dangerous situations. For this reason, we propose an energy-saving mining lamp with mine danger detection function. Summary of the invention

[0005] The purpose of the present invention is to provide an energy-saving mining lamp with a mine hazard detection function to solve the problem that existing mining lamps cannot be combined with gas detection systems, and that fixed mining lamps and portable mining lamps cannot provide evacuation instructions to mine workers in response to dangerous situations.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is an energy-saving mining lamp with a mine danger detection function, comprising a fixed lighting assembly and a portable lighting assembly, wherein several of the fixed lighting assemblies comprise a transparent lamp stand fixedly mounted on the surface of a mine tunnel wall, and a fixed lamp arranged inside the transparent lamp stand, and an infrared gas concentration sensor is fixedly arranged at the bottom of the transparent lamp stand, all the fixed lighting assemblies are connected in parallel circuits, and each of the fixed lighting assemblies is provided with an independent backup power supply; the portable lighting assembly comprises a head-mounted lamp stand, and a mobile lamp and a mobile power supply are fixedly mounted on the surface of the head-mounted lamp stand, and the mobile lamp is electrically connected to the mobile power supply; the fixed lighting assembly and the portable lighting assembly both establish a communication control connection with a detection system;

[0008] The detection system includes a real-time monitoring module, and a lighting module, a detection module, an early warning module and a guidance module that establish communication connections with the real-time monitoring module.

[0009] Real-time monitoring module: used to display the mine data provided by all fixed lighting components and portable lighting components in the mine in the form of a map, including the lighting conditions of each fixed lamp and mobile lamp and the gas detection data of each infrared gas concentration sensor; the mine data is displayed in a central interface;

[0010] Lighting module: used to control the lighting conditions of all fixed lighting components and portable lighting components inside the mine, including the independent backup power supply of each fixed lighting component, whether the fixed lamps are in normal use, the repair and replacement records of fixed lamps, the location data of the portable lighting components, and the information of the user wearing the portable lighting components; each of the fixed lighting components and each portable lighting component is set with an independent number and entered into the digital map of the mine to display its location;

[0011] Detection module: used to detect the gas concentration at the location through the infrared gas concentration sensor set in each fixed lighting component, and send the gas concentration detection data to the real-time monitoring module in real time. The monitoring module displays the gas concentration detection data of the gas sensors at various locations in the mine on the central interface;

[0012] Early warning module: used to warn the system administrator when abnormal gas concentration detection data appears, and formulate an early warning plan, which includes: immediately notifying the mine workers at the location of abnormal gas concentration in the mine to evacuate the dangerous area in the form of broadcast, and monitoring the location of abnormal gas concentration to determine whether there is a portable lighting component wearer at the location of abnormal gas concentration. If there is, keep the early warning until the gas concentration data at the location of abnormal gas concentration is normal or there is no portable lighting component wearer in the area;

[0013] Guidance module: used to safely guide the wearer of the portable lighting assembly through the wireless network communication connection established between the fixed lighting assembly and the portable lighting assembly. The guidance method includes the following:

[0014] Among them, when the infrared gas concentration sensor at the fixed lighting component position detects an abnormal gas concentration, the wireless communication network set up inside the fixed lighting component at the abnormal gas concentration position starts to connect all portable lighting components within the radiation range of its wireless network and the fixed lighting components at the normal gas concentration position to the network, and all mobile lamps in the portable lighting components wirelessly connected to the fixed lighting components at the abnormal gas concentration position start to flash, and the closer the mobile lamp is to the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position, the faster the flashing frequency is, until the mobile lamp leaves the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position, and the mobile lamp stops flashing; all fixed lighting components at the normal gas concentration position that are wirelessly connected to the fixed lighting components at the abnormal gas concentration position start independent backup power supplies to adjust the output power of the fixed lamps, and the closer the mobile lamp is to the fixed lighting components at the abnormal gas concentration position, the higher the output power is, that is, the brighter the fixed lamp is; the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position is the danger zone, and the wearers of the portable lighting components in the danger zone are guided to escape according to the flashing frequency of the mobile lamps in the portable lighting components they wear and the brightness of the fixed lamps in the fixed lighting components at the normal gas concentration position.

[0015] Preferably, the independent backup power supply in the fixed lighting component regularly provides lighting power to the fixed lamps until the independent backup power supply loses half of its power and then replenishes power; the fixed lighting component is directly allocated lighting power by the mine, and the fixed lamps and mobile lamps are all LED lamps, the higher the output power, the higher the brightness of the fixed lamps and mobile lamps.

[0016] Preferably, the real-time monitoring module also includes the following: supporting the initiation, classification and viewing of mine work tasks, and setting necessary attributes for the tasks, the attributes including task name, task description, execution time, task status and task executor;

[0017] Located in the center interface, global monitoring is performed based on the overall 3D view of the mine. The monitoring page includes: panoramic view, gas concentration data statistics and dynamic information prompt bar, providing real-time three-dimensional layout of the mine, key operating data and the latest safety notifications.

[0018] Preferably, the installation position of the fixed lighting assembly includes a mine gas inspection point, the fixed lighting assembly is installed on the top of the mine passage, and the infrared gas concentration sensor is 30 cm away from the top wall of the mine passage.

[0019] Preferably, the network node in the detection module uses an infrared gas concentration sensor to collect an analog signal of the incident light intensity of the gas gas, and after conversion by an A / D converter, a digital signal P0 of the incident light intensity of the gas gas is obtained. The detection module combines the digital signal of the incident light intensity of the gas gas to calculate and obtain the gas concentration of the mine:

[0020] P=P0exp(-α(ν)τQL) (1)

[0021] In the formula, α(ν) is the gas absorption coefficient; ν is the light source frequency; L is the optical path; τ is the adjustable factor; Q is the gas concentration;

[0022] From formula (1), we know that the underground gas concentration Q is calculated by P and P0. When the infrared gas concentration sensor collects the incident light intensity of the gas, the emitting light source will be adjusted by electrical modulation, resulting in changes in ν and P0. When the central wavelength is located on the gas absorption peak, the output light intensity is simplified to be calculated as follows:

[0023]

[0024] Where, β is the light intensity adjustment coefficient; ω is the modulation frequency; t is the time; α0 is the pure gas to be measured; λ is the frequency adjustment amplitude; δ V is the half line width;

[0025] Fourier technology is used to expand equation (2) to obtain the first harmonic and second harmonic components R1=P0β, From R1 and R2, we know that R1 has nothing to do with the gas concentration, while R2 does. Therefore, the gas concentration is calculated by the ratio of R2 to R1.

[0026] Preferably, the early warning module performs statistical analysis on the gas concentration data of each fixed lighting component position collected by the detection module. If the gas concentration exceeds a preset value, a danger warning is immediately issued and a danger report is generated.

[0027] Preferably, the detection system also includes a storage module: the storage module is used to store the gas concentration detection data of each fixed lighting component position, and generate relevant position numbers to store the gas concentration detection data for system administrators to review, and at the same time store the wearer information of the portable lighting component. The system administrator verifies the identity information of the wearer of the portable lighting component and then stores it.

[0028] The present invention has the following beneficial effects:

[0029] 1. The present invention connects fixed lighting components with portable lighting components in a communication state, and each fixed lighting component is provided with a wireless network. When the gas concentration at the location of a fixed lighting component is abnormal and may cause danger, the wireless network on the fixed lighting component automatically matches and connects all portable lighting components and other fixed lighting components within its wireless radiation range, and controls the mobile lamps in the matched and connected portable lighting components to start flashing. The faster the flashing frequency, the closer it is to the fixed lighting component, that is, the closer it is to the danger center. The slower the flashing frequency, the farther it is from the fixed lighting component, that is, the farther it is from the danger center. After leaving the wireless network radiation range of the fixed lighting component, the connection with the portable lighting component is disconnected. At this time, the mobile lamps of the portable lighting component no longer flash, which means it is out of danger. At the same time, the output power of the remaining fixed lighting components connected to the fixed lighting component gradually increases according to the distance from them. The closer the distance to the fixed lighting component is, the greater the output power of the remaining lighting components is, and the higher the brightness of the fixed lamps is. Through these two identification methods, the staff in the danger area can be quickly evacuated to avoid the presence of staff in the danger area.

[0030] 2. The present invention arranges an infrared gas concentration sensor on a fixed lighting component, and combines the gas concentration sensor with the lighting fixture. When the infrared gas concentration sensor detects abnormal gas concentration data, it directly transmits the gas concentration data at that location to the detection system. The detection system issues an early warning to the mine through an early warning module, and sets the dangerous area range according to the wireless network radiation range inside the fixed lighting fixture. It monitors whether there is a portable lighting component connected to it within the dangerous area. If so, it maintains an early warning state until the gas concentration data at the abnormal gas concentration location becomes normal or there is no portable lighting component wearer in the area, and then stops the early warning. In this way, the safety dynamics of the staff inside the mine can be accurately displayed.

[0031] 3. The present invention changes the brightness of fixed lamps within the danger zone by setting the output power of fixed lamps. The greater the brightness, the higher the danger level. This intuitive danger alarm method is used to remind mine workers. At the same time, the portable lighting components worn by the workers begin to flash. The workers can respond to the danger quickly and judge the escape direction according to the brightness of the fixed lighting components to guide the workers to escape. This guidance method is simple and effective. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Among them, when the infrared gas concentration sensor at the fixed lighting component position detects an abnormal gas concentration, the wireless communication network set up inside the fixed lighting component at the abnormal gas concentration position starts to connect all portable lighting components within the radiation range of its wireless network and the fixed lighting components at the normal gas concentration position to the network, and all mobile lamps in the portable lighting components wirelessly connected to the fixed lighting components at the abnormal gas concentration position start to flash, and the closer the mobile lamp is to the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position, the faster the flashing frequency is, until the mobile lamp leaves the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position, and the mobile lamp stops flashing; all fixed lighting components at the normal gas concentration position that are wirelessly connected to the fixed lighting components at the abnormal gas concentration position start independent backup power supplies to adjust the output power of the fixed lamps, and the closer the mobile lamp is to the fixed lighting components at the abnormal gas concentration position, the higher the output power is, that is, the brighter the fixed lamp is; the wireless network radiation range of the fixed lighting components at the abnormal gas concentration position is the danger zone, and the wearers of the portable lighting components in the danger zone are guided to escape according to the flashing frequency of the mobile lamps in the portable lighting components they wear and the brightness of the fixed lamps in the fixed lighting components at the normal gas concentration position.

[0049] Among them, the independent backup power supply in the fixed lighting component regularly provides lighting power to the fixed lamps until the independent backup power supply loses half of its power and then replenishes power; the fixed lighting components are directly allocated lighting power by the mine, and both the fixed lamps and mobile lamps are LED lamps. The higher the output power, the higher the brightness of the fixed lamps and mobile lamps.

[0050] The real-time monitoring module also includes the following: support for initiating, classifying and viewing mine work tasks, and setting necessary attributes for tasks, including task name, task description, execution time, task status and task executor;

[0051] Located in the center interface, it performs global monitoring based on the overall 3D view of the mine. The monitoring page includes: panoramic view, gas concentration data statistics and dynamic information prompt bar, providing real-time 3D layout of the mine, key operating data and the latest safety notifications.

[0052] Among them, the installation position of the fixed lighting component includes the mine gas inspection point position. The fixed lighting component is installed on the top of the mine passage, and the infrared gas concentration sensor is 30 cm away from the top wall of the mine passage.

[0053] Among them, the network node in the detection module uses an infrared gas concentration sensor to collect the analog signal of the gas incident light intensity. After conversion by the A / D converter, the digital signal P0 of the gas incident light intensity is obtained. The detection module combines the digital signal of the gas incident light intensity to calculate and obtain the mine gas concentration:

[0054] P=P0exp(-α(ν)τQL) (1)

[0055] In the formula, α(ν) is the gas absorption coefficient; ν is the light source frequency; L is the optical path; τ is the adjustable factor; Q is the gas concentration;

[0056] From formula (1), we know that the underground gas concentration Q is calculated by P and P0. When the infrared gas concentration sensor collects the incident light intensity of the gas, the emitting light source will be adjusted by electrical modulation, resulting in changes in ν and P0. When the central wavelength is located on the gas absorption peak, the output light intensity is simplified to be calculated as follows:

[0057]

[0058] Where, β is the light intensity adjustment coefficient; ω is the modulation frequency; t is the time; α0 is the pure gas to be measured; λ is the frequency adjustment amplitude; δ V is the half line width;

[0059] Fourier technology is used to expand equation (2) to obtain the first harmonic and second harmonic components R1=P0β, From R1 and R2, we know that R1 has nothing to do with the gas concentration, while R2 does. Therefore, the gas concentration is calculated by the ratio of R2 to R1.

[0060] Among them, the early warning module performs statistical analysis on the gas concentration data of each fixed lighting component position collected by the detection module. If the gas concentration exceeds the preset value, a danger warning is immediately issued and a danger report is generated.

[0061] Among them, the detection system also includes a storage module: the storage module is used to store the gas concentration detection data of each fixed lighting component position, and generate relevant location numbers to store the gas concentration detection data for system administrators to review, and at the same time store the wearer information of the portable lighting component. The system administrator verifies the identity information of the wearer of the portable lighting component and then stores it.

[0062] In the present invention, a large amount of gas detection data approximately obeys the normal distribution through probability distribution fitting. Based on this, the calculation formula for constructing the gas concentration warning threshold range is as follows:

[0063]

[0064] Among them, x1,x2,...x n A set of historical detection data of n measuring points x is used as the analysis sample. Generally, the historical data within the most recent period is taken, which is 30 days by default, and the sample data is updated dynamically; is the average value of the sample data; k is the probability density. According to the 3σ rule, the default value is 3. Generally, is the standard deviation of the data sample, which mainly reflects the degree of dispersion of discrete data that conforms to the normal distribution;

[0065] According to formula (3), the gas concentration warning range of the measuring point is calculated in real time and updated to the system configuration as the basis for determining the gas warning state. When the measuring point value exceeds this limit range, a warning message is issued.

[0066] When personnel use it, by connecting the fixed lighting components with the portable lighting components in a communication state, a wireless network is set on each fixed lighting component. When the gas concentration at the location of a fixed lighting component is abnormal and may cause danger, the wireless network on the fixed lighting component automatically matches and connects all portable lighting components and other fixed lighting components within its wireless radiation range, and controls the mobile lamps in the matched portable lighting components to start flashing. The faster the flashing frequency, the closer it is to the fixed lighting component, that is, the closer it is to the danger center. The slower the flashing frequency, the farther it is from the fixed lighting component, that is, the farther it is from the danger center. When leaving the wireless network radiation range of the fixed lighting component, the connection with the portable lighting component is disconnected. At this time, the mobile lamps of the portable lighting component no longer flash, which means it is out of danger. At the same time, the output power of the remaining fixed lighting components connected to the fixed lighting component gradually increases according to the distance from them. The closer the distance to the fixed lighting component, the greater the output power of the remaining lighting components, and the higher the brightness of the fixed lamps. Through these two identification methods, the staff in the danger area can be quickly evacuated to avoid the presence of staff inside the danger area.
