The problem that prior art exists is: the GPS positioning precision of civilian level is >10m all generally, if improve its precision to m level, 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 high pedestal jib crane, rotating mechanism and luffing mechanism carry out position monitoring, the spatial position data of many high pedestal jib cranes of needs collection transmission.
Summary of the invention
The object of the invention is to design for the deficiencies in the prior art a kind of many crane collision resistant monitored control systems based on light volume and wireless network, adopt radio network data communication technology that the main frame PLC being arranged on each hoisting crane is connected by WLAN, form the control system of many crane arm supports of Real-Time Monitoring and walking, for providing actv., the monitoring of many hoisting crane positions quantizes reference system, effectively monitor the spatiality of jib, realize the Anti-bumping protection of many hoisting crane cross-operation, having avoided greatly jib to occur to wipe with periphery object in the course of the work touches, guarantee the lifting safe in operation of hoisting crane when cross-operation, simple in structure, 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 of many crane collision resistant monitored control systems based on light volume and wireless network, comprise the PLC main frame being arranged on each hoisting crane, industrial computer, photoelectric encoder and frequency converter, photoelectric encoder is arranged on the jib rotation/luffing mechanism and crane travelling gear of hoisting crane, 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 frames adopt WLAN to connect and compose the anticollision protection system of many 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 collision risk region and warning or the stoppage protection program of crane arm support, when crane arm support enters hazardous location, by PLC main frame, send and report to the police or send stoppage protection signal to frequency converter, realize the real-time monitoring of many hoisting cranes and the dynamic demonstration of industrial computer.
Described PLC main frame is provided with wireless network card and Ethernet interface to obtain the spatial positional information of adjacent hoisting crane.
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 many hoisting crane cross-operation; precision is high; cost is low; for providing actv., the monitoring of many hoisting crane positions quantizes reference system; effectively monitor the spatiality of jib; having avoided greatly jib to occur to wipe with periphery object in the course of the work touches; guarantee the lifting safe in operation of hoisting crane when cross-operation; optimized the operational method that in the past only depends on personal monitoring; can improve production security; increase production efficiency, reduce driver's operation intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Consult accompanying drawing 1, the present invention is comprised of the PLC main frame 1, industrial computer 2, photoelectric encoder 3 and the frequency converter 5 that are arranged on each hoisting crane 4, and PLC main frame 1 is connected with industrial computer 2, photoelectric encoder 3 and frequency converter 5; Described photoelectric encoder 3 is arranged on the jib rotation/luffing mechanism 41 and crane travelling gear 42 of hoisting crane 4; Described jib rotation/luffing mechanism 41 and crane travelling gear 42 are driven by frequency converter 5, and described several PLC main frames 1 adopt WLAN to connect and compose the anticollision protection system of many hoisting cranes 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 collision risk region and warning or the stoppage protection program of hoisting crane 4 jibs; when hoisting crane 4 jibs enter hazardous location, by PLC main frame 1, send and report to the police or send stoppage protection signal to frequency converter 5, realize the real-time monitoring of many hoisting cranes 4 and the dynamic demonstration of industrial computer 2.Photoelectric encoder 3 access PLC main frames 1 on described every hoisting crane 4, by PLC main frame 1, control frequency converter 5 and drive jib rotation/luffing mechanism 41 and crane travelling gear 42 operations, the Control loop that forms hoisting crane 4, the spatial positional information of its adjacent hoisting crane 4 is by AP network equipment 6 this PLC of input main frames 1; Described PLC main frame 1 is provided with wireless network card and Ethernet interface to obtain the spatial positional information of adjacent hoisting crane 4.Described photoelectric encoder 3 is connected with PLC main frame 1 by field bus communication interface.
