Abstract
At present, the guidance mode of college students’ career planning guidance system is imperfect, resulting in too long submission time. A college students’ career planning guidance system based on B/S three-tier architecture is designed. Hardware part: on the basis of obtaining the sensor dynamic compensation filter, expand 6 static memory; Software part: obtain the influencing factors of College Students’ career planning, combined with the external environment, use the B/S three-tier architecture to set the guidance mode, formulate the links of career planning, adopt the hierarchical management mode, and design the role authority management function of the system. Experimental results: the average submission time of the college students’ career planning guidance system designed this time and the other two systems is 11.277s, 16.253s and 15.554s, which proves that the college students’ career planning guidance system integrating the B/S three-tier architecture has a better effect.
Highlights
At present, the career mentioned by people can be divided into broad sense and narrow sense
Career refers to the complete career process of obtaining professional ability, cultivating professional interest, choosing a career, taking office, and completely withdrawing from professional labor
The narrow sense of career refers to the beginning of professional study or vocational training before working until the end of professional labor and leaving the job
Summary
The career mentioned by people can be divided into broad sense and narrow sense. The front-end conditioning circuit filters the sensor output signal and adjusts it to the acceptable range of ADC, and the digital signal is processed by dynamic compensation algorithm, The processing results are saved to the external expansion memory, and the data is transmitted back to the computer through the USB interface for display and analysisTMS320F2812 chip of the system mainly needs two voltages to supply power for it, one is the chip peripheral interface voltage of 3.3V, and the other is the chip core power supply of 1.8V. Texas Instruments provides users with a very representative function library, which collects highly optimized and accurate mathematical function library for developers, and accurately converts floating-point algorithm into operation code of fixed-point algorithm on TMS320F2812 chip These functions are often used in programs with intensive real-time calculation, and the running speed and accuracy are very important. The hardware design steps of the system are completed
