[0046] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a control system for a chemiluminescence imaging instrument, including a control module 10 and a voltage monitoring module 20; the voltage monitoring module 20 includes an analog switch 21, a first filter circuit 22 and a follower circuit 23, the input terminal of the analog switch 21 is used to connect to a power supply, the input terminal of the first filter circuit 22 is electrically connected to the output terminal of the analog switch 21, the input terminal of the follower circuit 23 is electrically connected to the output terminal of the first filter circuit 22, and the output terminal of the follower circuit 23 is electrically connected to the first input terminal of the control module 10.

[0047] For example, the control module 10 can be a microcontroller, etc.; the microcontroller model can be STM32F103VET6, etc.

[0048] In this embodiment, after the analog switch 21 is turned on, the power supply voltage is filtered by the first filter circuit 22 to remove power supply noise, and the voltage signal is impedance matched and buffered by the follower circuit 23. Finally, a stable signal is input to the control module 10, which calculates the voltage value of the power supply to determine whether the power supply voltage is stable.

[0056] In this embodiment, the voltage switching circuit 41 controls the power supply switching, providing power supply voltage to the light source driving circuit 43. The buffer circuit 42 isolates signal interference. The control module 10 sends a control signal to the light source driving circuit 43 through the buffer circuit 42. After receiving the control signal, the light source driving circuit 43 converts the control signal into a driving signal to control the brightness or on / off state of the light source. Thus, the voltage switching circuit 41 achieves rapid power switching, avoiding flickering during the initial stage of light source activation; the buffer circuit 42 prevents signal distortion; and the light source driving circuit 43 ensures stable operation of the light source, comprehensively improving the response speed and stability of light source control.

The fourth pin of the relay 414 is electrically connected between the collector of the transistor 412 and the anode of the Zener diode 413. The fifth pin of the relay 414 serves as the output terminal of the voltage switching circuit 41.

[0058] In this embodiment, the resistor divider circuit 411 divides the input voltage and outputs it to the base of the transistor 412. The transistor 412 turns on or off according to the base voltage, thereby driving the coil of the relay 414 to engage or disengage. Simultaneously, the fourth pin of the relay 414 is electrically connected between the collector of the transistor 412 and the anode of the Zener diode 413, suppressing voltage spikes through reverse breakdown characteristics and protecting circuit components.

[0060] In this embodiment, the fan drive module 50 receives the fan drive command signal from the control module 10 and drives the fan to run. The active heat dissipation design effectively reduces the internal temperature of the chemiluminescence imaging instrument, avoiding performance degradation or failure of electronic components caused by high temperatures.
