I. Giới thiệu
Đây là hệ thống kỹ thuật thay thế người thuyết minh trong trưng bày, toàn bộ đề cương cho thuyết minh hệ thống trưng bày được đọc và thu âm trong hệ thống lưu trữ tại hệ lưu trữ của máy chủ. Khách tham quan có thể cầm thiết bị nhận và phát tín hiệu lên các tầng trưng bày, qua hệ thống thiết bị, khách tham quan có thể hiểu và tiếp nhận toàn bộ nội dung trưng bày.
Sử dụng công nghệ thuyết minh không dây của Đức.
Quy trình lắp đặt thiết bị:
– Trung tâm lưu trữ dữ liệu và máy tính.
– Đầu nhận tín hiệu của máy cầm tay.
– Antaine (ăng –ten) phát tín hiệu theo tần số đã định.
– Dây truyền tín hiệu nhận và dây truyền tín hiệu phát được đi song song từ nơi đặt thiết bị đến nơi xử lý thông tin và tín hiệu
Ưu điểm: Khách tham quan tham quan độc lập, không có người thuyết minh. Thiết bị có 2 loại cho 2 thứ tiếng: tiếng Việt, tiếng Anh; Tương lai có thể lắp đặt nhiều thiết bị với nhiều thứ tiếng khác nhau, nhằm thuận lợi cho khách tham quan nước ngoài.Tuỳ thuộc vào số lượng khách tham quan đến thăm.
