Description
Technical field
The utility model relates to a kind of network monitoring system for things, refers more particularly to a kind of mine pressure monitoring system based on Internet of Things.
Background technology
Strata behavior analysis of roadway monitoring comprises the contents such as Observation of rock displacement of roadway, roadway roof absciss layer monitoring, anchor pole (rope) load-bearing monitor, coal and rock stress monitoring.Roadway displacement is basic strata behavior analysis of roadway Contents for Monitoring, and Observation of rock displacement of roadway content comprises that the amount of shifting near, the amount of crushing, pucking amount, two help relatively to shift near Liang He lane side displacement to roof and floor relatively.It is the problem that people pay close attention to always in recent years that Study on Monitoring Technology is pressed in ore deposit.Domestic, in the middle and later periods in 20th century, there have been various mechanical top board observation instruments, but most of top plate drilling mode that adopts is installed and manual observation record, measurement data is few, more discrete, be difficult to continuity and real-time that reaction top board state parameter strictly according to the facts changes, can not predict rapidly the generation sign of top board disaster, and on purpose implement the measure of preventing and reducing natural disasters initiatively.1990 Shandong Mineral College independent developments successes the forecast of DKJ-1 coal mine roof plate and computer supervisory control system, this system can arrive ground-based computer by cable transmission by the pressure information collecting, and system is mainly used in monitoring and forecast first weight and periodic weighting.1993, Shandong Province dragon Rocca instrument and meter for automation company and University Of Science and Technology Of Shandong jointly develop and have released ZYDC-1 type fully-mechanized mining working calculation of pressure crane monitoring system, this supervisory system can connect at most 196 monitoring points of 64 extension sets, at tens workplaces such as Yanzhou mineral group, Huainan coal electricity company, Datun Coal and Power Co., apply, obtained good result of use.At present, that in succession develops both at home and abroad presses all kinds displacement, the strain gauge of monitoring for ore deposit, its precision, the linearity etc. all improve a lot, yet application in down-hole is not very desirable, mainly concentrates on installation of sensors difficulty, sensitivity, impact resistance etc. not high.In mine pressure monitoring system, after obtaining the data of sensor, the data obtained need to be sent on main frame, the mode that transmits data is all wired data transmission, such as adopting I2C bus, RS485 bus etc.In sum, no matter be domestic or external at present, mine pressure monitoring system mainly be take wired monitoring as main, data transmission is all the wire transmission mode adopting, though wire transmission mode data rate is fast, reliability is high, there is difficult wiring, environmental suitability shortcoming poor, that be easily difficult to overcome by plant equipment damage, cost is high, maintenance workload is large etc.The monitoring of roadway displacement mainly utilizes mechanical type or electronic instrument manually regularly to detect, this detection mode measurement efficiency and precision are low, artifical influence factor is large, the more important thing is and is difficult to realize automatic transmission, the processing of measurement result and comprehensively analyzes.Technology of Internet of things is as a kind of emerging technology, and its develop rapidly is pressed monitoring for ore deposit new means are provided.
