Scan controller basd on GPRS with internet and control center controls automatic scan on the cartoon neon ad board and establishes TCP/IP link with control center through GPRS Modem and corrects cartoon data of scan controllers by using the link so as to realize automatic remote renew.
By applying the AT40K FPGA which is based on Dual-SRAM and integrated in FPSLIC and the high performance embedded RISC AVR core,the high resolution of the sending and receiving PWM signals was achieved and then the convert between automatic and manual operation was made easier.
The method can be used not only to calculate FSIQ in the complex power systems with simple or multiple faults, but also to analyze and evaluate the performance of the protective relays and automatic devices based on FSIQ.
A new feature extraction method using the amplitude fluctuation property of target HRRP for radar automatic target recognition
The research and realization about automatic abstracting based on text clustering and natural language understanding
A method of realization of automatic abstracting based on text clustering and natural language understanding is explored, aimed at overcoming shortages of some current methods.
The method makes use of text clustering and can realize automatic abstracting of multi-documents.
