Fig. 3 representes the non-master-slave mode networking of the utility model hydraulic support monitor control system data upload sketch map, from Fig. 3, can draw, and the utility model and the tunnel crossheading control centre computer interface that produces coal are realized the interlock of work plane coal excavation apparatus.For example when the face guard withdrawal is broken down; Bracket controller 13 is regained the feeler signal judgment according to face guard; Report crossheading control centre computer, crossheading control centre computer sends instruction through the coal-winning machine power station to coal-winning machine, makes it stop automatically advancing.Working surface hydraulic support controller 13 and produce coal between the tunnel crossheading control centre computer and to adopt CAN or RS485 bus to carry out data communication.Carry out data communication through optical cable between crossheading control centre computer and the aboveground ground monitoring central computer; Critical data, motion flow, equipment state and the failure condition real-time Transmission of working surface hydraulic support to the ground monitoring center, realized the networking monitoring of hydraulic support coal mining process.At the ground monitoring center, adopt advanced OPC technology, only need method through OPC interface accessing opc server; Do not need own stand-alone development driver; The hardware knowledge that need not understand bottom just can realize reading the data of hardware, has greatly simplified the complexity of ground monitoring software development, has shortened software development cycle greatly; Improve the reliability and stability of running software, also be convenient to the upgrading and the maintenance of system simultaneously.After adopting OPC technology independent development ground monitoring software, reduced demand, also reduced the integrated expense of ground monitoring system commercial configuration software.
Fig. 4 representes the automatic coal winning technology flow chart of the non-master-slave mode networking monitor control system of the utility model hydraulic support, and detailed process is following:
At first be installed in initial station to coal-winning machine, operating personnel's manual operation is all released all support push rods during original state, releases length and equals the coal cutting degree of depth, and put the coal seat in the plane and the face guard withdrawal of preceding number formulary platform support.Operating personnel can start the interlock function on any controller that satisfies condition; Consider the error of coal-winning machine position; When the coal machine advanced to the optional position after interlock started, many supports in coal-winning machine the place ahead were received wall supporting automatically in advance, several support auto spraying a period of times before and after the coal-winning machine; After the coal of the intact segment distance of coal mining machine cut left, wall supporting and pushing and sliding are tried to stop people from fighting each other, stretched to the support of back automatically.After coal-winning machine arrived the end, coal-winning machine rollback inverted running cut the triangle coal, and the support at coal-winning machine rear is tried to stop people from fighting each other automatically; After coal-winning machine leaves snake type curve regions, the automatic pushing and sliding of support in triangle coal district, this pushing and sliding process is until the end; The triangle coal is cut in the operation of coal-winning machine forward then; When coal-winning machine once more behind the end, the coal cutting process of this direction finishes, then by whether reverse coal cutting of operating personnel's decision.System has the function of automatic detection coal-winning machine direction, and inconsistent with actual coal machine direction like the coal machine testing direction that system shows, then system adjusts automatically.
For the professional and technical personnel, can draw a series of improvement by above description, these improvement should be included in all protection domains of dependent claims.
