Technical field
The utility model relates to a kind of control systems, and in particular to a kind of Mine-used Belt Conveyor classification redundancy control system.
Background technique
Main shaft belt feeder is extremely important to coal production, can not normally produce coal once being unable to operate normally, and guarantees main shaft
The reliable and stable operation of belt feeder is most important.In view of this consideration, Ma Jiliangkuang increases a standby variable frequency device, Ke Yishi
It now when a wherein frequency converter failure, can not be repaired in the short time, so that it may which cracking investment standby variable frequency device is realized
Main shaft belt feeder uninterruptedly produces coal.Present main shaft belt feeder centralized control system uses S7-300 series of PLC, once there is CPU damage
It is bad, also main shaft belt feeder can be caused to be unable to operate normally.
In view of this consideration, using S7-400H redundancy scheme.When this system operates normally, the work of host CPU is
Execute corresponding control command, and spare CPU, then it is the operating status for detecting host CPU by link, it is run and makes guarantor
Card.When host CPU breaks down, spare CPU then can timely be put into use rapidly.It is carried out when with host CPU
When the module of communication is in corresponding state of activation, and host CPU is able to access that its input/output module, carries out data
Acquisition and the control of information complete its main task then can control whole system.
Since one, two belt conveyor frequency converters of horse spine mine main entry are placed on ground, underground is guided to by long cable
Fire-proof motor causes underground control equipment and ground frequency converter apart from far, the operating condition of this particularity to control system can
It is required by property very high.Be related to whole system reliability key point have the redundancy of control system CPU, underground control equipment with
The remote diagnosis that the control and later maintenance of the communication network, ground frequency converter of ground installation need.

Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1, Mine-used Belt Conveyor provided by the utility model is classified redundancy control system comprising interchanger 100 becomes
Frequency device 200, controller 300, spare controller 400 and security control case 500.
Interchanger 100 is communicated to connect by each control equipment of Ethernet and underground, in this way by each control of underground
Control equipment is all hung on looped network, even if some point on looped network disconnects, normal communication is can still be maintained in whole network, from
And improve the reliability of system.
Frequency converter 200 is connect with interchanger 100, can control each control equipment to work by interchanger 100.
Controller 300 controls equipment for ontology, and model is specially S7-300, is connect with interchanger 100, is to use
Signal is controlled to each control equipment of frequency converter 200 and underground in sending.
Spare controller 400, model are specially S7-400H, are also connect with interchanger 100, be for spare, when
When controller 300 damages, sealing-tape machine work can also be controlled by spare controller 400.
In addition, it is superfluous to be respectively equipped with two four-way fiber optical transceiver compositions on controller 300 and spare controller 400
Co-net network, redundant network connect frequency converter 200, are respectively equipped with emergency stop switch on security control case and controller 300, emergency stop is opened
Pass is connect with dry contact fiber optical transceiver, accordingly even when controller 300 and spare controller 400 are all damaged encountering emergency situations
Afterwards, staff can also be latched frequency converter 200 by emergency stop switch, it is ensured that in emergency circumstances can emergency stop frequency converter 200, from
