Description
Technical field
The present invention relates to mine engineering monitoring field, a kind of underground mine remote online telemetry system tree-shaped is more particularly to
Topologic network method, it is adaptable to the mine engineering remote online remote measurement networking such as underground mine.
Background technology
With continuing to increase for China's energy, the increase of resource and traffic rigid demand and mining rate, superficial part resource is
Increasingly depleted.But compared to superficial part engineering, deep engineering rock mass is due to the Special complex power in typical " three disturbances high "
Learn under environment, great changes will take place for its mechanical characteristics, the effect of tectonic geology factor and environmental effect, knot while rock mass is originally experienced
Structure patterns affect, is a kind of discontinuous, heterogeneous, anisotropic body and viscoelastic media on mechanical characteristic, therefore, its power
Learn form or constitutive relation shows extremely complex nonlinear characteristic, so that the current or even following quite a long time,
All it is difficult to by the numerical simulation computational methods based on traditional theory, obtains the stability being actually consistent completely with engineering and quantitatively tie
Really.Thus, by monitoring means, Test in Situ deformation, STRESS VARIATION information are obtained, and on this basis, further deeply divide
Analysis, discloses the mechanism rule of rock mass deformation and destruction, final to realize so as to take scientific and rational rock mass structure control device
Mine safety is exploited, as one of most important technological means necessary to current mining production.
Currently, show that in Coal Mine Disasters, roof accident occurrence frequency is higher according to national security supervision general bureau statistical report,
More heavy casualties and huge economic losses is caused, while bad social influence is also brought, therefore, emphasis is opened
Exhibition Roof Monitor turns into the center of gravity of Mine Monitoring work.It is summed up, existing Roof Monitor is main with deformation monitoring, stress monitoring
Based on, while with the fast development of optics, electricity, sensor technology, distributed information processing and radio network technique,
The New Mine remote online telemetry system of the generation bus control system of one class combining global the 5th and GPRS technologies, due to height
Frequency acquisition, automatically analyze, remote collection the advantages of, routine monitoring is successfully replaced, be progressively applied to underground mine engineering.
(《Safety of coal mines》, the 37th phase in 2009, inscribe one's name " application of deep tunnel real-time displacement monitoring system ", author Liu Xunchen etc.,《Gold

In order to achieve the above object, the present invention is achieved by the following technical solutions：A kind of underground mine remote online
Telemetry system tree topology network-building method, on the top board in the more than two goafs of underground mine, by design spacing difference cloth
If displacement meter, bolt stress meters, displacement meter, bolt stress meters are connected by holding wire with channel processor respectively, two or more
Channel processor be connected on root bus cable one end by branch cable bus respectively, the connection of the other end of root bus cable
Ground monitoring center.
By adopting the above-described technical solution, a kind of underground mine remote online telemetry system tree topology group of the invention
Network method, mainly with advantages below：
(1) branch node bus is substituted with root bus, gathered data is collected and is transmitted to Surveillance center, reduce order wire
Road total length, compared to existing other network topology networking structures, tree-like networking is easier to expand in structure, so that can spirit
Reply mining Plan rescheduling living, it is secondly, separate between each tree-like branch system under tree topology, when a certain branch line
Road instrument breaks down, and manually can rapidly realize isolation, the stability of safeguards system collection.
(2) realize that instrument circuit is concentrated in tunnel using channel processor, be easy to protection, and then reduce production and transport work
Industry, construction blasting excavate the destruction probability to circuit, while channel processor can also increase communication strength, and to abnormal sensing
Device realizes isolation, so that the normal instrument of effective guarantee is interference-free, complete independently data transfer.
(3) networking mode of the present invention can completely compatible different types of sensor, and to access sensor quantity and
Position does not limit.Tree topology network-building method is used simultaneously, mine spatial structure characteristic is effectively combined, and can evade well work
Limitation of the unfavorable factors such as coal mine working environment complexity to monitoring, simultaneity factor is simple to operate, is easy to safeguard, can fully protect
The continuity that barrier underground mine goaf monitoring system is accessed, with stronger application value.
