Development Of Distributed Bird Drive System For Railway Contact Line Based On Wireless Communication

Contact line system is the main transmission equipment for railway traffic.In recent years,more and more transmission line accidents were caused by bird activities,which seriously affect the normal operation of the railway.Most work of driving bird are destroy the nest by artificial,this method has low efficiency,and consume a lot of manpower and material resources,the ordinary bird driving device position is dispersion,it is not easy to manage and collect the alarm data,therefore,Therefore,commissioned by the power supply section of a railway bureau,develop a set of contact net automatic bird system,to achieve the record of the activities of birds,communication management,commissioned by the enterprise,develop automatic driving bird system,which can record the activities of birds,and realize communication management,it is of great significance to promote the safe operation of the railway system.Through situation of field,analysis of the birds characteristics and position distribution,make the overall scheme of the bird driving system.Which including a control master station and several distributed bird driving substations,the bird driving sub stations installed on the contact line equipment,the master control station get the bird driving substations work situation through the Modbus wireless communication module,monitor and record the alarm information through the PC software,and establish database management,display through the man-machine interface.Carried out detailed design of bird driving substation,including power supply device,wireless module slave machine,infrared detection device,bird driving unit,equipment protection device and mechanical structure,the master control station includes industrial control computer and wireless communication module host,then,complete the design of the electrical diagram,design and manufacture of the electric control cabinet and mechanical installation structure,complete the circuit layout and assembly work.As to the software of the bird driving system,studied the Modbus wireless communication technology,realize the instruction and data interaction between the host and slave in the range of communication distance.designed the host computer monitoring software system by C# programming language,designed the serial communication,the man-machine interface,the automatic operation mode,the manual operation mode and the database management,which to realize the display,processingand recording of the communication data,realize driving birds automatically.At present,the development and installation of the bird driving system has been completed,based on the analysis of the bird driving system operation data,the system realizes the automatic driving of birds,achieved the requirements of development.
