[0021] The main control module is electrically connected to each voltage conversion module and sampling module. The main control module detects whether each output sampling voltage is abnormal. When any output sampling voltage is abnormal, the main control module controls the voltage conversion module corresponding to the abnormal output sampling voltage to stop outputting the drive voltage, while maintaining the voltage conversion module corresponding to the normal output sampling voltage to continuously output the drive voltage.

[0034] Please see Figure 1 This is a schematic diagram of the power management system 100 according to a preferred embodiment of this application. The power management system 100 includes a power supply device 10, a power management device 20, and multiple loads 30_1 to 30_n.

[0035] The power supply device 10 is used to convert alternating current (AC) into a working voltage and supply it to the power management device 20. The power supply device 10 includes at least one switching power supply module 11_1 to 11_m, where m is a positive integer greater than or equal to 1. In at least one embodiment of this application, the switching power supply modules 11_1 to 11_m are alternating current (AC)-to-direct current (DC) power supply modules used to convert AC voltage to DC voltage. In at least one embodiment of this application, when multiple switching power supply modules 11_1 to 11_m of the same specifications are connected in parallel, current sharing is required before input to the power management device 20. In other embodiments, the power supply device 10 also includes only one switching power supply module 11_1 to 11_m.

[0036] The power management device 20 receives the output voltage provided by the power supply device 10 and generates a drive voltage for the loads 30_1 to 30_n based on the output voltage. In at least one embodiment of this application, n is a positive integer greater than or equal to 1. The power management device 20 includes a main control module 21, multiple voltage conversion modules 22_1 to 22_n, and a sampling module 23.

[0037] The main control module 21 is electrically connected to the power supply unit 10. The main control module 21 is used to power on and operate according to the operating voltage provided by the power supply unit 10. In at least one embodiment of this application, the main control module 21 can be a main controller unit (MCU). The main control module 21 is further electrically connected to a plurality of voltage conversion modules 22_1 to 22_n. The main control module 21 is also used to generate output control signals to the voltage conversion modules 22_1 to 22_n to control the voltage conversion modules 22_1 to 22_n to switch between an operating mode and a shutdown mode. The output control signals can switch between a first level and a second level. In at least one embodiment of this application, the first level is a low level (e.g., ground voltage), and the second level is a high level (e.g., operating voltage).

[0038] Each voltage conversion module 22_1~22_n corresponds to a load 30_1~30_n and is electrically connected between the main control module 21 and the corresponding load 30_1~30_n. Each voltage conversion module 22_1~22_n switches between an operating mode and a shutdown mode according to an output control signal. When the output control signal is at the second level, the voltage conversion module 22_1~22_n switches to the operating mode and outputs a drive voltage to the corresponding load 30_1~30_n to drive it to work. When the output control signal is at the first level, the corresponding voltage conversion module 22_1~22_n switches to the shutdown mode and stops outputting a drive voltage to the corresponding load 30_1~30_n, thereby stopping the corresponding load 30_1~30_n from working. In at least one embodiment of this application, the voltage conversion modules 22_1~22_n are DC-DC conversion modules, and the drive voltage can be adjusted according to the needs of the load 30_1~30_n.

[0039] The sampling module 23 is electrically connected to both the main control module 21 and multiple voltage conversion modules 22_1 to 22_n. The sampling module 23 is used to sample the drive voltage output by each voltage conversion module 22_1 to 22_n to obtain the output sampling voltage, and then send the output sampling voltage to the main control module 21.

[0040] The main control module 21 further generates an output control signal for the voltage conversion modules 22_1 to 22_n based on the output sampling voltage. Specifically, when the output sampling voltage is greater than or equal to the output threshold voltage, the main control module 21 identifies an abnormal output sampling voltage. When the output sampling voltage is abnormal, it identifies an abnormality in the loads 30_1 to 30_n connected to the voltage conversion modules 22_1 to 22_n corresponding to the abnormal output sampling voltage. The main control module 21 generates an output control signal at a first level for the corresponding voltage conversion modules 22_1 to 22_n. The corresponding voltage conversion modules 22_1 to 22_n switch to a shutdown mode based on the first-level output control signal and stop outputting the driving voltage to the corresponding loads 30_1 to 30_n, thus stopping the corresponding loads 30_1 to 30_n from operating. When the output sampling voltage is less than the output threshold voltage, the main control module 21 identifies a normal output sampling voltage. When the output sampling voltage is normal, it identifies a normal load 30_1 to 30_n connected to the voltage conversion modules 22_1 to 22_n corresponding to the normal output sampling voltage. The main control module 21 generates an output control signal at the second level to the corresponding voltage conversion modules 22_1~22_n. The corresponding voltage conversion modules 22_1~22_n switch to the working mode according to the output control signal at the second level and output the driving voltage to the corresponding loads 30_1~30_n so that the corresponding loads 30_1~30_n can work normally.

[0041] The sampling module 23 further samples the working voltage to obtain the input sampling voltage and transmits it to the main control module 21.

[0042] The main control module 21 is also used to detect whether there is an abnormality in the input sampling voltage. Specifically, when the input sampling voltage is greater than or equal to the input threshold voltage, the main control module 21 identifies that the input sampling voltage is abnormal and outputs a power-off signal to control the power supply device 10 to switch to the off mode. When the input sampling voltage is less than the input threshold voltage, the main control module 21 identifies that the input sampling voltage is normal and stops outputting the power-off signal.

[0043] The power management device 20 further includes a first communication module 24. The first communication module 24 is used to communicate with the power supply device 10. The first communication module 24 transmits a power-off signal to the power supply device 10. In at least one embodiment of this application, the first communication module 24 communicates with the power supply device 10 based on the Inter-Integrated Circuit (I2C) communication protocol.

[0044] The first communication module 24 is also used to acquire real-time power information of each switching power supply module 11_1~11_m and transmit it to the main control module 21. The real-time power information includes output voltage, output current, and internal temperature.

[0045] The main control module 21 is also used to detect whether there are any abnormalities in the real-time information of each power supply. When there is an abnormality in the real-time information of the power supply, the main control module 21 outputs a power-off signal to the switching power supply modules 11_1~11_m corresponding to the abnormal real-time information, and the switching power supply modules 11_1~11_m corresponding to the abnormal real-time information switch to the shutdown mode according to the power-off signal. When there is no abnormality in the real-time information of the power supply, the main control module 21 outputs a stop output power-off signal to the switching power supply modules 11_1~11_m corresponding to the normal real-time information, and the switching power supply modules 11_1~11_m corresponding to the normal real-time information maintain the output operating voltage.

[0046] In at least one embodiment of this application, when the output voltage, output current or internal temperature exceeds the corresponding upper limit threshold, the main control module 21 identifies that there is an abnormality in the real-time power supply information; when the output voltage, output current or internal temperature does not exceed the corresponding upper limit threshold, the main control module 21 identifies that there is no abnormality in the real-time power supply information.

[0047] After the first communication module 24 transmits a power-off signal to the power supply device 10, the main control module 21 further detects whether the power supply device 10 has switched to the off mode. If the first communication module 24 fails to work or the power supply device 10 fails to stop working according to the power-off signal, the main control module 21 further generates a forced shutdown signal and sends it to the power supply device 10 through the first communication module 24.

[0048] The power management device 20 also includes a remote control module 25. The remote control module 25 is used to provide a forced shutdown signal generated by the main control module 21 to the power supply device 10. In at least one embodiment of this application, infrared communication is used between the remote control module 25 and the power supply device 10.

[0049] Loads 30_1 to 30_n are powered on and operated according to the driving voltage output by the corresponding voltage conversion modules 22_1 to 22_n. In at least one embodiment of this application, loads 30_1 to 30_n can be multiple different power-consuming modules within the same gene sequencer. Loads 30_1 to 30_n can be power-consuming modules such as gene sequencing biochemical platforms, Ethernet switches, operation and control platforms, optical platforms, CANFD servers, industrial control computers, display platforms, and fluid components within the gene sequencer, or they can be the same power-consuming modules within different gene sequencers; no limitation is made here. In at least one embodiment of this application, the power management device 20 and the loads 30_1 to 30_n transmit output data based on the Controller Area Network with Flexible Data Rate (CANFD) protocol. The power management device 20 can send power management data to at least one load 30_1 to 30_n.

[0050] The power management system 100 further includes a server 40. Loads 30_1 to 30_n communicate with the server 40. Loads 30_1 to 30_n can provide biological detection data and received power management data to the server 40. The server 40 is used to analyze and monitor the biological detection data and power management data.

[0051] Based on the aforementioned gene detection system 1, each load 30_1~30_n corresponds to a voltage conversion module 22_1~22_n for independent power supply. The sampling module 23 individually detects the voltage of each voltage conversion module 22_1~22_n. If any of these modules experiences an abnormality, the main control module 21 controls the voltage conversion module 22_1~22_n corresponding to the abnormal output sampling voltage to stop outputting the drive voltage, while maintaining the continuous output drive voltage of the voltage conversion module 22_1~22_n corresponding to the normal output sampling voltage, thus improving the safety protection level of the loads 30_1~30_n. Simultaneously, the power management device 20 further monitors the power supply device 10 from multiple angles, further enhancing the safety protection level of the loads 30_1~30_n.

[0053] Furthermore, the functional modules in the various embodiments of this application can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one unit. The integrated unit can be implemented in hardware or in the form of hardware plus software functional modules.
