Prior art Problems existing is: the general all >10m of GPS positioning precision of civil, to improve its precision to m level, then need to set up ground base station, the construction cost of ground base station is obviously higher than the cost of high pedestal jib crane control system, the signal of satellite radiocommunication is subject to weather effect, satellite-signal is easily disturbed, and the operating unit of every platform high pedestal jib crane, rotating mechanism and luffing mechanism carry out position monitoring, need the spatial position data of collect and transmit multiple stage high pedestal jib crane.
Summary of the invention
The object of the invention is to design for the deficiencies in the prior art a kind of volume based on light and the multiple stage crane collision resistant monitored control system of wireless network, radio network data communication technology is adopted to be connected by WLAN by the main frame PLC be arranged on each hoisting crane, form the control system of Real-Time Monitoring multiple stage crane arm support and walking, monitoring for multiple stage crane location provides actv. and quantizes reference system, the spatiality of effective monitoring jib, realize the Anti-bumping protection of multiple stage hoisting crane cross-operation, avoid jib greatly to touch with periphery object generation wiping in the course of the work, guarantee the lifting safe in operation of hoisting crane when cross-operation, structure is simple, easy to operate, reduce driver's operation intensity, production safety and efficiency improve greatly.
The object of the present invention is achieved like this: a kind ofly compile and the multiple stage crane collision resistant monitored control system of wireless network based on light, comprise the PLC main frame be arranged on each hoisting crane, industrial computer, photoelectric encoder and frequency converter, on the jib rotation/luffing mechanism that photoelectric encoder is arranged on hoisting crane and crane travelling gear, PLC main frame and industrial computer, photoelectric encoder is connected with frequency converter, jib rotation/luffing mechanism and crane travelling gear are by transducer drive, be characterized in that several PLC main frame adopts WLAN to connect and compose the anticollision protection system of multiple stage hoisting crane cross-operation by AP network equipment, described AP network equipment is arranged on the hoisting crane of center, operating area, described PLC main frame is provided with the collision risk region of crane arm support and warning or stoppage protection program, sent by PLC main frame when crane arm support enters hazardous location and report to the police or send stoppage protection signal to frequency converter, realize the real-time monitoring of multiple stage hoisting crane and the Dynamic Announce of industrial computer.
Described PLC main frame is provided with wireless network card and Ethernet interface to obtain the spatial positional information of adjacent cranes.
Described photoelectric encoder is connected with PLC main frame by field bus communication interface.
The present invention compared with prior art has the Anti-bumping protection of multiple stage hoisting crane cross-operation; precision is high; cost is low; monitoring for multiple stage crane location provides actv. and quantizes reference system; the spatiality of effective monitoring jib; avoid jib greatly to touch with periphery object generation wiping in the course of the work; guarantee the lifting safe in operation of hoisting crane when cross-operation; optimize in the past only by the operational method of personal monitoring; production security can be improved; increase production efficiency, reduce driver's operation intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Accompanying drawings 1, the present invention is made up of the PLC main frame 1 be arranged on each hoisting crane 4, industrial computer 2, photoelectric encoder 3 and frequency converter 5, and PLC main frame 1 is connected with industrial computer 2, photoelectric encoder 3 and frequency converter 5; On the jib rotation/luffing mechanism 41 that described photoelectric encoder 3 is arranged on hoisting crane 4 and crane travelling gear 42; Described jib rotation/luffing mechanism 41 and crane travelling gear 42 are driven by frequency converter 5, and described several PLC main frame 1 adopts WLAN to connect and compose the anticollision protection system of multiple stage hoisting crane 4 cross-operation by AP network equipment 6; Described AP network equipment 6 is arranged on the hoisting crane 4 of center, operating area; Described PLC main frame 1 is provided with the collision risk region of hoisting crane 4 jib and warning or stoppage protection program; sent by PLC main frame 1 when hoisting crane 4 jib enters hazardous location and report to the police or send stoppage protection signal to frequency converter 5, realize the real-time monitoring of multiple stage hoisting crane 4 and the Dynamic Announce of industrial computer 2.Photoelectric encoder 3 on described every platform hoisting crane 4 accesses PLC main frame 1, controlling frequency converter 5 by PLC main frame 1 drives jib rotation/luffing mechanism 41 and crane travelling gear 42 to run, the Control loop of composition hoisting crane 4, the spatial positional information of its adjacent cranes 4 then inputs this PLC main frame 1 by AP network equipment 6; Described PLC main frame 1 is provided with wireless network card and Ethernet interface to obtain the spatial positional information of adjacent cranes 4.Described photoelectric encoder 3 is connected with PLC main frame 1 by field bus communication interface.
The present invention installs and work like this: driver's cab PLC main frame 1 and industrial computer 2 being arranged on hoisting crane 4, AP network equipment 6 is arranged on a certain hoisting crane 4 of center, operating area, be arranged on each jib rotation/luffing mechanism 41 to be connected with PLC main frame 1 by field bus communication interface with the photoelectric encoder 3 on crane travelling gear 42, the PLC main frame 1 accessing WLAN network of multiple stage hoisting crane 4 is formed complete Control loop by AP network equipment 6, operating personal can on the industrial computer 2 of driver's cab or touch-screen this hoisting crane of Real time dynamic display 4 and adjacent hoisting crane 4 position.The locus coordinates transmission of hoisting crane 4 position coordinate data and jib compares and Logic judgment to the position data of PLC main frame 1, PLC main frame 1 by ownship position data and adjacent hoisting crane 4 by photoelectric encoder 3.When Operation system setting is monitoring pattern: when the jib of high pedestal jib crane 4 enters hazardous location, the buzzerphone alarm apparatus in driver's cab and industrial computer 2 Dynamic Announce, remind driver to carry out operation adjustment in time.When Operation system setting is automatic protected mode: PLC main frame 1 sends the guard signal of auto-stop to frequency converter 5, realize the real-time monitoring of multiple stage hoisting crane 4, effective monitoring multiple stage high pedestal jib crane 4 position.Quantize reference system for operating personal provides actv., the jib that largely avoid maloperation and high pedestal jib crane 4 enters hazardous location, guarantees to lift by crane safe in operation, greatly reduces driver's operation intensity.
More than just the present invention is further illustrated, and be not used to limit this patent, allly implements for the present invention's equivalence, within the right that all should be contained in this patent.
