Description

Technical Field

[0001] This utility model relates to the field of rescue and safety device technology, specifically a smart mine emergency management device. Background Technology

[0002] Mining accidents trigger a series of severe consequences. The power supply system is instantly disrupted, ventilation systems are damaged, and underground communication lines and facilities suffer partial or even catastrophic damage, leading to communication disruptions. As a result, surface rescue personnel are completely unaware of the situation inside the mine. In such circumstances, rescue teams must enter the disaster area to conduct reconnaissance and promptly report back on the mine's disaster situation. Only then can the rescue command center accurately grasp the nature and scope of the accident, understand the number and location of those in danger and those who have perished, and know the environmental conditions inside the mine, such as ventilation, toxic gases, and temperature. Based on the reconnaissance results, the rescue command center can fully understand the disaster situation and make correct decisions.

[0003] Because the mine's existing communication equipment was damaged, information transmission within the mine was interrupted after the accident. Relying on the mine's existing communication equipment was impossible, and immediately laying rescue fiber optic cables would be too time-consuming. For rescue operations where time is of the essence, fiber optics could only serve as a supplementary communication method, operating concurrently with the rescue efforts. However, relying on human relay was too outdated. Therefore, rescue personnel entering the mine mostly relied on temporary wireless communication equipment to transmit information about the situation inside. However, emergency rescue sites require a large number of communication frequency resources; furthermore, the metal supports, rock strata, and water within the mine reflect or absorb electromagnetic waves, resulting in severe signal transmission loss. Therefore, signal transmission for rescue personnel underground was extremely difficult.

[0004] To enhance communication during rescue operations, most existing technologies employ methods such as frequency enhancement and switching to improve wireless transmission. For example, patent document CN209083336U discloses a mine rescue wireless communication system. This system utilizes a switching module to switch the operating frequency range to an underground operating frequency range. The system then converts user input information into a wireless signal within the underground operating frequency range and transmits it. This allows for wireless communication in underground tunnels, caves, and other underground engineering sites.

[0005] While the above-mentioned technical solutions can enhance wireless signal transmission and solve the problem of wireless transmission difficulties in mines to some extent, they are still essentially wireless signals and will still be reflected or absorbed by metal supports, rock strata and water in the mine. When faced with complex mine environments, their effect is not ideal. When the signal is interrupted, the ground cannot obtain information about the rescue situation in the mine, cannot carry out management and dispatch, and does not know where the signal is interrupted, so it cannot be maintained and communication restored in time. Utility Model Content

[0006] The purpose of this utility model is to provide a smart mine emergency management device to solve the technical problems mentioned above in the prior art, such as short communication distance of wireless network node devices, weak anti-interference ability, and susceptibility to reflection or absorption by metal supports, rock strata and water in the mine, resulting in unsatisfactory performance in complex mine environments.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: a smart mine emergency management equipment, characterized in that: it includes a dispatch system vehicle, a portable signal transmission base station and several mobile communication devices;

[0008] The dispatching system vehicle includes a programmable dispatch console module, which includes multiple programmable dispatch consoles, all of which are connected to the same programmable switch.

[0009] The mobile communication device includes an explosion-proof walkie-talkie, a positioning wristband, and a smart safety helmet;

[0010] The signal transmission base station includes acoustic repeaters and microwave repeaters;

[0011] The mobile communication device is connected to the vehicle-mounted electrical system of the dispatch system via a portable signal transmission base station, and is used to construct a wireless communication rescue ring network.

[0012] The beneficial effects of this implementation plan are as follows:

[0013] 1. In existing technologies, rescue personnel entering mines mostly rely on temporary wireless communication equipment to transmit information about the situation inside the mine. However, emergency rescue sites require a large number of communication frequency resources; and the metal supports, rock strata, and water in the mine reflect or absorb electromagnetic waves, resulting in severe signal transmission loss. Therefore, signal transmission is difficult for underground rescue personnel. When the signal is interrupted, the ground cannot obtain information about the rescue situation inside the mine, cannot carry out management and dispatch, and does not know where the signal interruption occurred, making it impossible to maintain and restore communication in a timely manner. This application sets up a multi-level wireless ring network architecture that connects mobile communication equipment and dispatch system vehicles through signal transmission base stations (including acoustic repeaters and microwave repeaters), forming a three-level link of "mobile terminal → base station → command center"; the microwave repeater uses 5G backhaul as the main means of communication, and the acoustic repeater uses low-frequency sound waves to penetrate rock strata obstacles to solve the problem of radio shielding underground as an auxiliary measure, ensuring uninterrupted communication in extreme environments such as collapses or gas leaks (improving the communication success rate by ≥80% in scenarios where traditional radio frequency signals fail).

[0014] 2. This application incorporates anti-interference and redundancy design, sharing the same program-controlled exchange with all program-controlled dispatch consoles, supporting multi-channel parallel calls and automatic routing switching, and ensuring that a single node failure does not affect the operation of the entire network; mobile base stations can form their own networks, and when the main dispatch vehicle is damaged, any base station can be upgraded to a temporary command node to avoid system crash.

[0015] 3. This application overcomes the three major challenges of "invisibility, inability to connect, and inability to control" in mine emergency response by integrating a mobile command vehicle with an acoustic relay communication ring network.

[0016] Furthermore, the acoustic repeater is selected as the ZY-SB-01 type downhole acoustic data transmission repeater.

[0017] Furthermore, the microwave repeater is selected as the SG-B20 type microwave repeater.

[0018] Furthermore, the acoustic repeater and microwave repeater employ gateway layer protocol conversion.

[0019] Furthermore, the dispatching system vehicle includes an on-board dispatching platform, which is the KJZ-200 type mining intelligent command platform.

[0020] Furthermore, the explosion-proof walkie-talkie is Hytera PD-790Ex, the positioning wristband is KJ139-F mining positioning terminal, and the smart safety helmet is KJZ-100A. Attached Figure Description

The acoustic repeater is model ZY-SB-01 downhole acoustic data transmission repeater, operating in the 100-500Hz frequency band, with a rock penetration distance of 1.5km. The microwave repeater is model SG-B20. The acoustic and microwave repeaters use gateway layer protocol conversion (e.g., unified scheduling by an SDN controller).

[0028] The portable signal transmission base station also includes a signal isolation and conversion module and a multi-protocol intelligent gateway module.

[0029] The signal isolation and conversion module enables bidirectional conversion and electrical isolation between acoustic (low-frequency) and microwave (high-frequency) signals, avoiding mutual interference.

[0030] DC / DC power supply isolation module: Built-in isolation power supply provides independent regulated power for acoustic wave sensors (such as piezoelectric chips) and microwave transceivers, ensuring signal stability.
