SMART LIGHT SOURCE REPLACEMENT APPARATUS AND FAULT JUDGEMENT REPLACEMENT METHOD FOR BIOCHEMICAL ANALYSER

摘要

A smart light source replacement apparatus and a fault judgement replacement method for a biochemical analyser. The smart light source replacement apparatus comprises a controller (14), a light source replacement device, a light-focusing convex lens (3), a testing cup (2), and a photodetector (1) and a power supply switching controller (15) which are connected to the controller (14). The light source replacement device comprises a support frame (18), a light source seat (9), a driving electric motor (10) and a driving rod (11). The light source seat (9) is located in the support frame (18). A working light source (4a) and a standby light source (4b) are provided on the light source seat (9). The light source seat (9) is provided on the driving rod (11) and the movement thereof is driven by the driving rod (11). The light-focusing convex lens (3), the testing cup (2) and the photodetector (1) are successively located at a front side of the working light source (4a). The working light source (4a) and the standby light source (4b) are respectively connected to the power supply switching controller (15). The light source replacement device can also be composed of a movable optical fibre (6) and the fixedly mounted light source seat (9).
