Monitoring and control system for mobile rescue cabin or fixed refuge chamber

Abstract

The invention relates to a downhole safety monitoring system for mines and in particular relates to a monitoring control system for a mobile rescue capsule or a fixed refuge chamber. The monitoring control system comprises a host sub-system, as well as a monitoring sub-system, a control sub-system and a communication sub-system which are connected with the host sub-system, wherein a host device of the host sub-system is connected with various detection sensors through intelligent interfaces to form the monitoring sub-system; the host device is connected with various environmental control devices through intelligent interfaces to form the control sub-system; and the host device is connected with a video device, a voice communication device and a networking system through intelligent interfaces to form the communication sub-system. According to the monitoring control system, various parameter sensor data and personnel number information can be collected in real time, the survival environment parameters are monitored and automatically regulated, and the monitoring data and the voice and video information are transmitted to a ground monitoring center and a control command is received by virtue of a downhole transmission network, so that the downhole safety monitoring system for mines is an essential core system of guaranteeing downhole safe production and emergency rescue of coal mines and non-coal mines.

Description

technical field [0001] The invention relates to an underground safety monitoring system for coal mines and non-coal mines, in particular to a monitoring and control system for a mobile rescue cabin or a fixed refuge chamber. Background technique [0002] Mobile rescue capsules or fixed refuge chambers originated in the United States and are widely used in coal and non-coal mines to prolong the life of underground disaster survivors and improve the success rate of external rescue. It has also been vigorously promoted in Canada, Australia and Europe. my country's Coal Mine Safety Supervision Bureau requires all coal mines to build underground "six safety systems", among which the emergency escape system is the key point, and mobile rescue cabins and fixed refuge chambers are emergency escape systems. The basic composition of the mobile rescue chamber and the monitoring and control system based on the fixed refuge chamber is the key to ensuring safety. At present, the mobile re...

Problems solved by technology

At present, the mobile rescue cabin imported from abroad has only a few sensors, which cannot meet the requirements of real-time transmission of underground monitoring data and control of living environment parameters; while the existing domestic underground safety monitoring and monitoring system is mainly used for coal mine mining face. Safety monitoring, such as a coal mine safety monitoring system disclosed in Patent No. 200910087321.9, has three functions of safety data collection and transmission, satellite telephone command and dispatch, and video on-site viewing, providing effective supervision means and solutions for coal production management departments , does not have the function of monitoring and controlling the living environment parameters of the mobile rescue cabin or the fixed refuge chamber; the mobile emergency rescue cabin monitoring device developed in China at present, such as the living environment control in the movable rescue cabin under the coal mine disclosed in CN 101825000A The system is limited to the control of the living environment in the mobile rescue cabin, and cannot communicate with the uphole. The rescue personnel on the well cannot keep abreast of the environment in the underground cabin and the situation of the people to be rescued, and the control of the living environment in the mobile rescue cabin needs to be done manually by the rescuers. control

Patent No. 200820090571.9 discloses an embedded mine chamber multifunctional refuge rescue cabin, which is an embedded inflatable refuge rescue cabin set in the mine chamber, and the rescue cabin body is provided with a rescue cabin bracket and a double-layer airtight door. A sealed zipper and an observation window are arranged on the outside of the airtight door, and a pressurized air line interface passing through the rescue cabin, a communication data line interface, an air hole in the rescue cabin and an exhaust valve of the rescue cabin are arranged on the rescue cabin. The cabin is equipped with dual-channel oxygen supply and CO2 purification gas system, power carrier communication machine, UPS power supply, RFID personnel identification system, video security monitoring system, toxic and harmful gas automatic detector, sealed physiological excretion device and survival food storage cabinet, The two-way oxygen supply system is equipped with air and oxygen centralized oxygen supply masks. This patent uses power carrier communication to communicate with rescuers on the well. However, once a mine accident occurs, the underground power system is usually destroyed and the communication will be cut off.

[0003] It can be seen that the above-mentioned existing monitoring and control system for underground mobile rescue cabins or fixed refuge chambers in coal mines and non-coal mines obviously still has inconvenience and defects in structure and use, and cannot meet the needs of domestic coal mines and non-coal mines. For the safety requirements of underground mobile rescue cabins or fixed refuge chambers, the relevant units have tried their best to find a solution, but no suitable design has been developed for a long time. This is obviously a problem that the relevant industry is eager to solve
