luận án tốt nghiệp Thiết Kế Tuyến Viba Số

KẾT LUẬN

 Qua 9 tuần làm luận án, đây là thời gia tương đối ngắn nhưng nhóm thực hiện đã
hết sức cố gắng để có thể thu thập những thông tin và các vấn đề liên quan đến
luận án và cuối cùng đã hoàn thành đúng thời gian quy đònh.

 Cũng qua luận án nhóm thực hiện đã học hỏi được nhiều kiến thức và kinh nghiệm
quý báu về ngề nghiệp của mình trong tương lai. Hiểu rõ những khó khăn cần phải
giải quyết khi bắt tay vào nghiên cứu một lónh vực khoa học mới, cần phải bố trí
thời gian một cách hợp lý khoa học thì mới có thể hoàn thành.

 Nội dung đề tài chia làm 3 phần chính:

Phần I: Lý thuyết thiết kế tuyến.
Gồm 9 bước cơ bản. Đây là phần lý thuyết nền tảng khi thiết kế một tuyến
Viba số. Nó là một trong những cơ sở để xây dựng một hệ thống theo yêu cầu. Trên cơ
sở đó ta có thể thấy được phẩm chất và độ tin cậy của hệ thống thiết kế có đạt yêu
cầu đặt ra hay không.
Phần II: Thiết kế và tính toán t uyến truyền dẫn Viba số thực tế.
Áp dụng các bước ở phần II,thiết kế vả tính toán cho một tuyến cụ thể.
Trong quá trình tính toán các thông số của đường truyền, em còn gặp một số khó
khăn đó là việc nghiên cứu về đòa hình cũng như tính chất của đất tại các trạm … (do
đó không tìm được các thông số một cách chính xác mà chỉ có tính tương đốùi).
 Qua nghiên cứu em nhận thấy rằng công việc tính toán các thông số của đường
truyền khá phức tạp với những công thức khá dài có liên quan với nhau nên dễ bò
sai sót nếu người thực hiện không quen và cẩn thận. Chính vì lí do trên nên em
sử dụng ngôn ngữ C đễ hỗ trợ cho việc tính toán, giúp ngưới thiết kế có thể an
tâm nhập các thông số cần thiết làm giảm đi rất nhiều các công việc tính toán
phức tạp và ít sai số.
 Đây là đề tài khá mới mẻ đối với em. Do thời gian và điều kiện còn hạn chế với
một khối lượng công việc khá lớn. Vì thế những sai sót là điều không thể tránh
khỏi.
 Trong đề tài này tuyếu thiết kế chỉ là một dạng cơ bản của hệ thống Viba
chuyển tiếp mà thôi. Hệ thống không sử dụng trạm lập chưa mang tính chất quốc
tế. Chính vì vậy đề tài này còn có thể được phát triển thêm nếu có điều kiện.
 Rất mong được tiếp tục nghiên cứu áp dụng thiết kế cho những hệ thống có qui
mô lớn.
 Một lần nữa em chân thành cảm ơn Q Thầy, Cô và sự hướng dẫn nhiệt tình
của Thầy NGUYỄN HUY HÙNG, cùng tất cả các bạn đã giúp em hoàn thành
luận án này.
