A Study in Monitoring and Management System for Mine Power Supply Network
Cui La
1999, 25(2): 11-12.
<Abstract>(44)
Abstract:
Microcomputerbased monitoring and management system for power supply system and power supply facilities in coal mine is introduced here. It can monitor operating mode of power supply system, related electric parameters and operating status of electric equipment, as well as conduct dynamic management for all power supply facilities and materials, which will greatly improve the management of coal mine network and use efficiency of the facilities and will benefit both safety and production in coal mines.
Selfadaptive Smith Preestimation Control Scheme for Timedelay System
Han Ru-cheng, Li Xiao-feng
1999, 25(2): 13-16.
<Abstract>(18)
Abstract:
The paper presents a selfadaptive smith preestimation control scheme for timedelay system. Smith predictor makes up of identificable parameter using RVFF(Recursive Variable Forgetting Factor Method) on line. FNNC (Fuzzy Neural Network Controller) is used as system controller. The simulation results show that the method is effective when parameter is changed.
Study on Common Channel Transmission with Speech and Signals for Inclined Shaft Man Vehicles
QI Ben-sheng, LIU Yu
1999, 25(2): 16-18.
<Abstract>(25)
Abstract:
This paper introduces a method of extracting the useful speech onoff signal based on the features of conversation speech, and the frame structures of implement voice/data integration in a single channel employing the speech interpolation technique.
Simulation Debugging of Main Control Software in KJ3Z Rail Haulage Monitoring System
ZHU Guo-yuan, PIAO Xi
1999, 25(2): 19-21.
<Abstract>(37)
Abstract:
Each basic channel in channel interlock table must be tested one by one to ensure the correct dispatchment of locomotive operation. If it is tested improperly, it will take a lot of labor and leave accident possibility which is more serious. The author puts forward an efficient method offline simulation debugging to debug the interlock table in system main control software.
