The technical scheme adopted by this utility model is which passes through to change the frequency regulation motor rotating speed of power supply, can be in work
When at any time according to elevator ruuning situation, make elevator be in optimum Working, using programmable controller to whole fortune
Row system be controlled can real-time monitoring, behave elevator more reliable.Wherein converter uses vector controlled
Technology, realizes accurate speed governing by changing frequency, completes the control relatively reliable to elevator.The system is using PLC high speeds
Counting module and high-speed counting port combine, and are acquired to being installed on motor shaft spindle encoder data, while monitoring side
To, speed, depth and prevent pulleying or car slipping, control the S-shaped rate curve of elevator operation by by PLC institutes coding
It is given, change through A/D, exported by analog output mouth, to drive converter to work.Rotary encoder can detect main electricity
The rotating speed of motivation, and send this signal to Programmable Logic Controller, PC application can be calculated by the signal and be carried
The speed of the machine of liter and travel distance, monitor can constantly show Hoist Speed and position.
Further, the Programmable Logic Controller signal is the Programmable Logic Controller of Siemens Company S7-300 series, as
Mine hoist frequency-converting speed-governing control system master controller.
Further, the MM440 type converters of converter model Siemens Company.
The beneficial effects of the utility model are that hoist control system is simple to operate, and stable and reliable operation improves speed governing
Effect, improves production efficiency.
