Description

Technical Field

[0001] The present invention relates to the technical field of mine maintenance, in particular to a wireless inspection and video communication system based on mine shaft operation. Background Art

[0002] A vertical shaft, also known as a shaft, is a vertical tunnel directly connected to the ground. A main shaft is used exclusively or mainly for lifting coal; an auxiliary shaft is used mainly for lifting gangue, lowering equipment, lifting personnel and other auxiliary lifting work. During the long-term operation of the vertical shaft, due to the multiple strata, complex geological conditions, and harsh operating environment, the vertical shaft will experience longitudinal, circumferential and radial strains. These strains are extremely difficult to detect in a short period of time. If the evolution of the shaft and its key facilities is not understood in time, it is very likely that the shaft will be skewed, the lifting body will be stuck at high speed due to long-term accumulation, and there will even be major accidents such as shaft rupture and water inrush, and the lifting body will fall due to broken ropes when the gradual accumulation turns into a sudden change.

[0003] The existing maintenance method is to use the cage and the winch room to communicate through a wired telephone or intercom, and then the winch room will make the control action.

[0004] The disadvantage of the traditional approach is that there are major safety hazards. If the cage is in operation, once the wired telephone is disconnected, the winch room cannot know and take measures in the first time, and a major accident is likely to occur. When there is a control demand in the cage, it must first be transmitted to the winch room through a wired telephone or intercom, and then the winch room will take action. This will make maintenance inconvenience and timeliness very poor.

[0005] In order to make corresponding improvements to the above shortcomings and integrate functions such as video communication, image monitoring, status display prompts, status voice indications, and mobile phone intercom, a wireless inspection and video communication system based on mine shaft operations is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a wireless inspection and video communication system based on mine shaft operations, which changes the current situation where shaft maintenance mainly relies on wired telephone and walkie-talkie communications, thereby avoiding the safety hazards of traditional maintenance methods and improving the convenience and timeliness of maintenance.
