Description

Technical Field

[0001] The utility model belongs to the field of coal mine safety monitoring, and in particular relates to a coal mine hydrological monitoring system based on Beidou short messages. Background Art

[0002] Hydrological monitoring and early warning are crucial for coal mine safety. Changes in groundwater conditions can trigger a series of serious disasters, such as water seepage, which not only pose a significant threat to the safety of underground workers but also severely disrupt the normal and orderly operation of coal mines.

[0003] In the prior art, a Chinese patent with publication number CN203669926U discloses a coal mine hydrological monitoring system, comprising a central monitoring station, a ground substation, and an underground substation. The ground substation includes a first hydrological monitor, the input of which is connected to a liquid level sensor, and the output of which communicates wirelessly with the central monitoring station via a wireless transmission module. The underground substation includes a second hydrological monitor, the input of which is connected to the monitoring equipment via a cable, and the second hydrological monitor is interactively connected to the central monitoring station via a cable. By utilizing a GSM wireless network and combining it with an industrial control network, real-time monitoring of hydrological parameters and over-limit early warning management are achieved during coal mining. By analyzing hydrological data trends based on hydrological parameter curves, mine water level, water temperature, and flow data can be obtained immediately, which is of great significance for guiding coal mine safety production and preventing and controlling water disasters. It also provides early prevention of possible water inrush incidents in mines, providing strong protection for people's lives.

[0004] In coal mining operations, mines are often located in remote, suburban areas. These areas often have unique geographical environments and infrastructure, and one of the most prominent issues is poor network coverage. Due to the relatively low population density and complex geographical environment in suburban areas, including natural terrain such as mountains, hills, and forests, the construction of conventional communication network base stations is difficult and costly. Consequently, existing network communication operators struggle to achieve comprehensive and stable network coverage in these areas, resulting in weak or even no network signal in suburban areas where coal mines are located.

[0005] Although the traditional coal mine hydrological monitoring system can monitor the hydrological conditions in the mine to a certain extent, it has obvious limitations in data transmission. Specifically, in the future, in the case of less or no people in coal mining, when the hydrological monitoring equipment in the mine obtains key hydrological parameters such as water level, water temperature, and water flow rate, due to the lack of effective network transmission channels, these data may be interrupted, delayed, or lost during transmission. This makes it difficult for remote monitoring personnel to accurately grasp real-time hydrological information in the mine, and thus unable to make effective early warning and prevention decisions in the first time.

[0006] Therefore, in the process of hydrological monitoring in the coal mine area, there is currently a lack of a stable and effective remote monitoring system. Practical new type content

[0020] Figure 1 This is a schematic diagram of a coal mine hydrological monitoring system based on Beidou short messages provided by an embodiment of the present utility model;

[0021] Figure 2 It is a schematic diagram of a hydrological monitoring module provided by an embodiment of the present utility model. DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The coal mine hydrological monitoring system based on Beidou short message in this embodiment is as follows: Figure 1 Shown, including:

[0024] Monitoring devices, ground monitoring equipment and remote monitoring centers;

[0025] The monitoring device is arranged in a coal mine observation well and comprises: a hydrological monitoring module and a transmission line;

[0026] The ground monitoring equipment is set on the ground in the coal mine area and includes: a data acquisition module, a Beidou communication module, a GPS antenna and a controller, wherein the data acquisition module, the Beidou communication module and the GPS antenna are respectively connected to the controller; the hydrological monitoring system is connected to the data acquisition module through a transmission line;

[0027] The remote monitoring center is connected to the Beidou short message communication module and receives the hydrological monitoring data transmitted from the ground monitoring equipment.

[0028] The monitoring device is installed in the coal mine observation well. It is a front-end device for obtaining underground hydrological data and is mainly composed of a hydrological monitoring module and a transmission line. The monitoring device includes any one or more of a water flow monitoring module, a water level monitoring module, and a water temperature monitoring module. Through these different types of monitoring modules, key hydrological parameters such as water flow velocity, water level height, and water temperature in the coal mine observation well can be fully and accurately monitored. For example, the water level monitoring module can sense the changes in the water level in real time. When the water level rises to the preset warning water level, it can trigger the corresponding early warning action in time; the water temperature monitoring module helps to understand the changes in groundwater temperature, which is also of great significance for analyzing the groundwater conditions and possible abnormal conditions.

[0029] In a preferred embodiment, the hydrological monitoring module further includes a first sound and light alarm. When the monitored hydrological parameters exceed the normal range, indicating a possible hydrological disaster risk, the first sound and light alarm immediately emits an audible and visual alarm signal to alert nearby underground workers to the danger and to take timely risk avoidance measures.

[0030] Furthermore, the hydrological monitoring module is also equipped with a camera that can capture real-time image information inside the observation well. These image data can help staff more intuitively understand the actual situation of the underground hydrological environment, such as whether there are water gushing points, water turbidity, etc., and further provide a strong basis for hydrological monitoring and disaster judgment.

[0031] The transmission line utilizes a shielded twisted-pair cable, coated with a waterproof, fireproof, and anti-static layer. This design ensures stable and reliable transmission of data collected by the hydrological monitoring module in the complex and harsh environment of underground coal mines. The shielded twisted-pair cable effectively reduces the impact of external electromagnetic interference on data transmission, while the protective layer protects the transmission line from potential underground hazards such as water, fire, and static electricity, ensuring continuous and accurate data transmission.

[0032] The ground monitoring equipment is a key part for receiving, processing and further transmitting the hydrological monitoring data transmitted from the underground. It mainly includes a data acquisition module, Beidou communication module, GPS antenna and controller. It is also equipped with a second sound and light alarm, a power management module and a backup power module.

[0033] The data acquisition module is connected to the hydrological monitoring module via a transmission line and is responsible for receiving various hydrological monitoring data transmitted by the hydrological monitoring module, such as water flow velocity, water level, and water temperature. It includes components such as a multiplexer and an analog-to-digital converter. The multiplexer can collect different types of data in a time-sharing manner, while the analog-to-digital converter converts the collected analog signals into digital signals for subsequent processing and analysis.

[0034] The Beidou communication module, connected to the controller, plays a crucial role in this system. It transmits processed hydrological monitoring data in the form of Beidou short messages, ensuring timely and stable data transmission to the remote monitoring center and related ground monitoring centers, even in situations where underground coal mine network coverage is poor or even nonexistent. The Beidou communication module also receives control commands from the remote monitoring center, enabling two-way communication, such as remote adjustment of monitoring parameters.

[0035] The GPS antenna is connected to the controller and is primarily used to obtain the geographic location of ground monitoring equipment. Accurate geographic location information not only allows for better positioning and management of ground monitoring equipment, but also helps accurately map the locations of coal mine observation wells and the source of relevant hydrological monitoring data, providing more comprehensive geographic information support for subsequent data analysis and disaster warnings.

[0036] The controller is the core control component of the ground monitoring equipment. It connects to the data acquisition module, Beidou communication module, and GPS antenna, coordinating the operation of the entire ground monitoring system. The controller performs preliminary processing and analysis of the collected data, determining whether hydrological conditions are abnormal. Based on this determination, it controls the Beidou communication module to transmit data and the second audible and visual alarm to issue an alarm signal.

[0037] When the controller determines that the hydrological conditions are abnormal, the second sound and light alarm will immediately send out an sound and light alarm signal to remind ground staff to pay attention to the hydrological conditions of the coal mine and take corresponding response measures in time, such as notifying underground staff to evacuate.

[0038] The power management module provides a stable power supply for the data acquisition module, Beidou communication module, GPS antenna, and controller. It features a power monitoring function that monitors power levels in real time. When power levels are low, the low-battery warning module issues a warning signal, alerting personnel to address the issue promptly and ensuring the normal operation of ground monitoring equipment.

[0039] To address potential power outages and other emergencies in coal mines, the ground-based monitoring equipment is equipped with a backup power module. If the main power source fails, the backup module can promptly take over, ensuring that the critical functions of the ground-based monitoring equipment are not affected and that hydrological conditions in the coal mine can be continuously monitored and warned.

[0040] The remote monitoring center is connected to the Beidou short message communication module to receive hydrological monitoring data transmitted from ground monitoring equipment. The remote monitoring center can be a mobile smart terminal (such as a mobile phone, tablet computer, etc.) or a computer terminal. Through the remote monitoring center, staff can intuitively view various hydrological monitoring data from coal mine observation wells, including real-time and historical values ​​of parameters such as water level, water temperature, and water flow rate. They can also receive early warning information from the system, enabling timely decision-making and the implementation of appropriate measures to ensure safe coal mine production.

[0041] In a preferred embodiment, the system of the present invention further includes a database module, which is respectively connected to the Beidou communication module and the remote monitoring center for receiving and storing hydrological monitoring data. The database module is located in a cloud server. By storing the hydrological monitoring data in the cloud, on the one hand, centralized data management and backup are achieved, preventing data loss; on the other hand, it facilitates staff in different locations to access and query the hydrological monitoring data at any time through the remote monitoring center, conduct data analysis and comparison, and thus better understand the changing trends of the coal mine hydrological conditions, providing a more favorable decision-making basis for coal mine safety production.

[0042] In one specific embodiment, a hydrological monitoring module continuously collects hydrological parameters in a coal mine observation well. For example, the water level monitoring module measures the water level in real time, the water flow monitoring module measures the water flow velocity, and the water temperature monitoring module measures the water temperature. Simultaneously, a camera continuously captures images of the observation well. The collected hydrological parameters are transmitted via a transmission line to the data acquisition module of the ground monitoring equipment. A multiplexer in the data acquisition module collects different types of data in a time-sharing manner. An analog-to-digital converter converts the analog signals into digital signals, and then transmits the processed digital data to a controller. The controller analyzes and processes the received data to determine whether the hydrological conditions are abnormal. For example, if the water level exceeds a preset warning level, the water flow velocity exceeds the normal range, or the water temperature changes abnormally, the controller determines that the hydrological conditions are abnormal. If the controller determines that the hydrological conditions are abnormal, it controls the Beidou communication module to transmit the hydrological monitoring data in the form of Beidou short messages to the remote monitoring center and relevant ground monitoring centers. It also controls the second audible and visual alarm to emit an audible and visual alarm signal to alert ground personnel to the coal mine's hydrological conditions.

[0043] The database module receives and stores the hydrological monitoring data transmitted by the Beidou communication module in the cloud server, making it convenient for staff to access and query the data at any time through the remote monitoring center.

[0044] The utility model utilizes satellites for remote communication, and can transmit effective and stable monitoring data even in remote coal mining areas, thus ensuring remote hydrological monitoring in coal mining areas with few or no people.

[0045] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
