The invention provides a mine flame-proof and intrinsic safety type signal converter and a system. The system comprises a signal converter, a relay and a corresponding explosion prevention box, wherein the signal converter is arranged beside an underground telephone near a coal mining machine under the ground and is respectively connected with the coal mining machine, the underground telephone and an underground telephone wire, and the relay is arranged in the middle of an underground telephone line. After the electrification, the real-time data of the hanged and connected coal mining machine is collected through matched software program, and the protocol conversion and the transmission are automatically carried out. The invention does not need single pavement of optical cables or electric cable lines, the telephone network universally existing in the coal mine is used for the signal transmission of the coal mining machine, in addition, the use of the underground telephone is not influenced, the implementation cost of the coal mine is reduced, and the effects of safety and reliability are realized. The invention conforms to the national coal safety requirements, has the advantages of high safety factor, stability, reliability, no manual operation and the like, and is suitable for various kinds of coal mining machine equipment such as digging equipment, extraction equipment, protection equipment and the like.
Description
technical field [0001] The invention relates to the technical field of communication in the coal mine environment, in particular to a mine flameproof and intrinsically safe signal converter and system. Background technique [0002] At present, in coal mine production, it is usually necessary to transmit the data information collected by the underground coal machine to the control equipment on the well, and transmit the commands and other information sent by the control equipment to the underground. Uphole and downhole communication generally adopt wired communication, and the media for wired communication are mostly optical cables, cables and other materials. Among them, twisted pair cables are more popular, and the communication network is usually deployed by directly laying communication media underground. In the communication process, depending on the technology and environment, the media required are also different. For example, optical fiber Ethernet technology requires...
