[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] In the related art, in order to save the data information in the system when the system loses power, the power supply is mainly provided in the following two ways: one is to add an electrolytic capacitor to the MCU, and the other is to use an external rechargeable battery or UPS. However, these two methods also have certain defects. The external electrolytic capacitor method can only provide a power-free time of ms. For systems with a large amount of information, the power-off retention time is not enough and cannot provide sufficient time for data preservation. The external rechargeable battery or UPS is expensive and large in size, and is not suitable for systems with cost or space constraints.

[0026] In order to solve the problems existing in the related art, an embodiment of the present application provides a power supply circuit system, which has low cost and can be integrated on a board, occupying a small space. The power supply circuit system is described below.

[0027] Figure 1 is a structural diagram of a power supply circuit system according to an embodiment of the present application, such as Figure 1As shown, the power supply circuit system 100 includes: a power module 10, a charging module 20, a first power supply module 30, a second power supply module 40 and a controller module 50, wherein the input end of the power module is used to connect to the gene sequencer, the output end of the power module is connected to the first input end of the charging module and the input end of the first power supply module, and the power module is used to supply power to the charging module and the first power supply module; the second input end of the charging module is connected to the output end of the first power supply module, and the output end of the charging module is connected to the controller module, which is used to charge the first power supply module when the gene sequencer is in a normal power supply state, and to supply power to the controller module, wherein the first power supply module is used to supply power to the controller module when the gene sequencer is in a power-off state; the output end of the second power supply module is connected to the controller module, which is used to supply power to the controller module when the power of the first power supply module is exhausted; the controller module is used to connect to the gene sequencer, monitor the power supply state of the gene sequencer, and save data information in the gene sequencer when the gene sequencer is in a power-off state.

[0028] It should be noted that the power on state means that the electronic device or system is connected to the power supply and the power supply is providing the required power to the device. In this state, the device can work and operate normally. For example, when a computer is connected to the power supply and turned on, it is in the power on state. At this time, the computer's CPU, memory, hard disk and other components will be supplied with power and can perform various computing and data processing tasks. In the power on state, users can edit files, run software, connect to the network and other operations. For servers or network devices, the power on state also means that they can provide services and respond to external requests.

[0029] It should be noted that the power off state refers to the state where an electronic device or system is disconnected from the power source and has no power supply. In this state, the device cannot perform any work that requires electricity. For example, when a computer is turned off and the power plug is disconnected, it is in a power off state. At this time, all parts of the computer will not work, all ongoing tasks will stop, the screen will turn black, and the hard disk will stop rotating. The power off state is usually used to save energy, reduce equipment loss, or protect the device when it is not in use. In addition, when performing certain hardware maintenance or replacing parts, it is also necessary to put the device in a power off state first to ensure safety.

The power supply +3.3V is filtered by capacitors C17, C18, C19, and C20 and then connected to the MCU chip U3.

[0054] The power supply circuit system provided in the embodiment of the present application monitors the input voltage in real time through the MCU to determine whether the external system is powered off. When the external system is not powered off, due to the unidirectional conductivity of the diode, the system MCU is powered only through the charging module, and the energy of the supercapacitor module and the button battery is not consumed. After the external system is powered off, the supercapacitor module supplies power to the MCU chip, and the supercapacitor power supply can be maintained for 1 minute. During this period, the supercapacitor is used to supply power without reducing the energy of the button battery. For systems with large amounts of data, a power-off maintenance time of 1 minute can already meet the storage time requirement. Similarly, with the help of the unidirectional conductivity of the diode, when the supercapacitor energy is exhausted, the battery power supply can be switched, and the button battery module is used as a necessary supplement to the power supply. When the system repeatedly loses power, that is, when the supercapacitor energy is exhausted and is not fully charged in time, and the power is lost again, the button battery module acts as a power-off backup power supply.

[0055] Therefore, the power supply circuit system provided in the embodiment of the present application can provide a min-level power-off time, which meets the time required to save when a system with a large amount of information loses power. It has low cost, occupies very little space, can be integrated into boards, and is very friendly to the entire system. In the case of abnormal power failure of the system during the sequencing process of the gene sequencer, key information of the sequencing process can be saved, which provides an effective means for troubleshooting, tracking, and analyzing instrument problems, and facilitates the location of instrument failure problems, thereby improving the speed and efficiency of quickly handling problems and helping to improve the quality of service to customers.

[0056] It should be noted that the above-mentioned power supply circuit system can not only be used in the medical field, such as gene sequencers, but also in industrial control and power management fields. It can monitor the power supply status of the external system in real time and provide additional power when the external system loses power to ensure timely storage of important data information.
