Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] The invention introduces the LonWorks technology into the downhole monitoring system. The LonWorks technology is a field bus technology released by Echelon Corporation of the United States in December, 1990. The communication speed of the LonWorks field bus is 2 to 5 times that of the traditional bus, and the communication protocol of the LonWorks field bus conforms to the Open Interconnection (OSI) model defined by the International Organization for Standardization (ISO), and any manufacturer's products are connected to the LonWorks field bus It can realize interoperability after all, and it can communicate with any medium, including twisted pair, power line, optical fiber, coaxial cable, radio wave, infrared ray, etc. Therefore, LonWorks technology has been more and more widely used at home and abroad.

[0032] Please refer to FIG. 2 , which is a structural ...

Abstract

The invention provides a downhole monitoring system which comprises a ground control center, a plurality of lightningproof bars, a plurality of base stations, a plurality of power boxes with explosion-protection and intrinsic safety, a plurality of sensors, communication cables and a plurality of transceivers. The plurality of base stations are arranged in each important detecting point of an downhole; a ground center control system is connected with the base stations through the communication cables; a LonWorks field bus mode is adopted for transmission, wherein, each base station comprises a wireless communication module, a singlechip and a nerve cell chip. The wireless communication module is used for radio-frequency wireless bidirectional communication with the transceivers and receiving the position and state information of a mobile target of the downhole. The singlechip is used for processing various monitored environmental parameters. The nerve cell chip is used for data transmission with the ground control center through the LonWorks field bus. The plurality of transceivers are arranged on the mobile target of the downhole and has wireless bidirectional communication with the base stations. The invention can make downhole operation safer and more reliable.

Description

technical field [0001] The invention relates to a communication technology, in particular to an underground monitoring system and monitoring method. Background technique [0002] Safety is the top priority for personnel working underground (the "well" mentioned later is "mine"). Safety not only guarantees, supports and promotes underground production, but also improves the ability to deal with emergencies. Therefore, Underground safety production is also an important part of national safety production. With the country's increasing emphasis on underground safety operations and the continuous strengthening of supervision, large and medium-sized mines and small mines in large towns and villages in my country have been equipped with a large number of underground safety production monitoring systems. The popularization and application of these safety equipment has greatly improved my country's mine safety production status . From the perspective of the development of undergroun...
