[0002] In modern laboratories and industrial environments, sample analyzers are important testing equipment and are widely used in medical, environmental monitoring, food safety and other fields. As a key component, the power management system plays a vital role. Existing power management systems are usually designed to be relatively simple. For example, a power switch (such as a rocker switch, etc.) is set for the sample analyzer. If the power switch is turned on, the entire sample analyzer is powered on. If the power switch is turned off, the entire sample analyzer is powered off.

[0003] However, the above method requires the user to operate the power switch on the body, which is inconvenient to operate and the user experience is poor. In addition, the above power-off method is likely to cause damage to the components of the sample analyzer, reducing the service life of the sample analyzer. Summary of the invention

[0025] In one embodiment of the present invention, if the main power switch is in the off state, the sample analyzer is in a fully shut down state;

[0026] In the case where there are multiple target switches and the sample analyzer is in a fully powered-off state, if the switching circuit detects a turn-on signal from the main power switch and receives a control signal for instructing a power-on operation, the multiple target switches are opened or turned on in sequence according to a preset power-on sequence to power on the multiple loads to be powered in sequence.

[0046] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0048] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0049] In order to facilitate understanding of the sample analyzer, the power on / off control method, and the sample analyzer assembly line provided by the present invention, several states of the sample analyzer involved in the present invention are explained below.

[0050] Power on: The entire sample analyzer is powered on.

[0051] Soft shutdown: By turning off the virtual switch, all or part of the loads to be powered of the sample analyzer are powered off.

[0052] Full shutdown: The entire sample analyzer is powered off. As you can understand, when the main power switch is turned off, the entire sample analyzer is powered off.

[0053] Ready state: All functional modules of the sample analyzer are powered on, in idle state and without faults, and the sample analyzer is in non-sleep state.

[0054] Combine the following Figures 1 to 10 , the sample analyzer, power on / off control method and sample analyzer assembly line provided by the present invention are explained.

[0055] See also Figure 1 , Figure 1 A schematic diagram of the structure of a sample analyzer provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the sample analyzer includes:

[0056] A power module 20, a power management module 40, and a signal transceiver 30, wherein the power module 20 comprises: an auxiliary power submodule 201 and a controlled power submodule 202;

[0057] The power module 20 is connected to the external AC power 10, and the external AC power 10 is used to power the signal transceiver 30 through the auxiliary power submodule 201; the signal transceiver 30 receives an external input control signal, and outputs the control signal to the controlled power submodule 202;

[0058] The controlled power submodule 202 includes a switching circuit 2021 and at least one AC / DC converter (such as Figure 1The AC / DC converter 1, AC / DC converter 2...AC / DC converter n) 2022 in the switching circuit 2021 includes at least one target switch, and the target switch corresponds to the AC / DC converter 2022 one by one. One end of the target switch is used to access the external alternating current 10, and the other end of the target switch is connected to the corresponding AC / DC converter 2022; the power management module 40 includes at least one DC / DC converter (direct current / direct current converter) 401, each of the AC / DC converter 2022 is connected to one of the DC / DC converters 401 (in some other optional embodiments, each of the AC / DC converter 2022 can be connected to two or three of the DC / DC converters 401, without limitation), the input end of the DC / DC converter 401 is connected to the corresponding AC / DC converter 2022, and the output end of the DC / DC converter 401 is connected to at least one load 50 to be powered of the sample analyzer.

[0059] The switching circuit 2021 is used to control the target switch based on the control signal to complete power-on or power-off control of the load 50 to be powered.

[0060] It should be noted that the sample analyzer can realize automatic power on or off control of each load 50 to be powered, that is, based on the control signal, it can realize automatic power on or off control of each load 50 to be powered, with low cost and strong feasibility.

[0061] The control signal may be a software signal, ie, a virtual signal triggered by software, or a physical signal, ie, a signal triggered by a hardware switch.

[0062] It can be understood that the DC / DC converter 401 is used to output the direct current output by the power module 20 into multiple direct currents, so as to supply power to multiple loads 50 to be powered.

[0063] The target switch may be a relay, an IGBT (Insulated Gate Bipolar Transistor), a BJT (Bipolar Junction Transistor), a MOS tube (Metal-Oxide-Semiconductor Field-Effect Transistor), a triode, and the like.

[0064] The load 50 to be powered includes a sensor module (such as a temperature sensor, a humidity sensor, etc.) of a sample analyzer, a signal processing module (such as a signal amplifier, a filter, etc.), a data analysis module (such as a microprocessor (MCU), etc.), and a communication module (such as Bluetooth, USB (Universal Serial Bus), etc.).

[0065] In some embodiments, the auxiliary power submodule 201 supplies power to the signal transceiver 30 via a preset AC / DC converter.

[0066] In some embodiments, the external AC power 10 can be commercial power or a generator, etc.

[0067] In some embodiments, the sample analyzer further comprises:

[0068] A power connector, used to connect to the external AC power 10 and transmit the external AC power 10 to the power module 20;

[0069] A main power switch, located between the power connector and the power module 20, for opening or closing the connection channel between the power connector and the power module 20;

[0070] The auxiliary power submodule 201 does not include a switch. When the main power switch is turned on, the auxiliary power submodule 201 is always in a powered state.

[0071] It should be noted that, since the auxiliary power submodule 201 is always in a powered state when the main power switch is turned on, the auxiliary power submodule 201 can continuously supply power to the signal transceiver 30, so that the signal transceiver 30 can receive and forward control signals in real time to control the switching circuit 2021 in the power module 20. By controlling the switching circuit 2021, the power on or off control of each load 50 to be powered can be achieved.

[0072] It should also be noted that the main power switch can be a mechanical switch such as a rocker switch, so as to facilitate power control of the entire sample analyzer. It can be understood that when the power connector is connected to the external AC power 10, if the main power switch is turned off, the entire sample analyzer is powered off, and if the main power switch is turned on, the power module 20 of the sample analyzer has the power supply capability.

[0073] In some embodiments, when the power connector is connected to the external AC power 10 and the main power switch is turned on, the sample analyzer is turned on, that is, the entire sample analyzer is powered on. On this basis, by controlling the switching circuit 2021, the sample analyzer can be softly turned off and on.

[0074] In some embodiments, the control signal includes a software feedback signal, a time trigger signal, a voice signal, and a physical switch signal. The software feedback signal refers to an on signal or off signal of a preset virtual switch. The time trigger signal refers to a signal triggered when a preset timed on / off time is reached. The voice signal refers to a signal triggered based on a voice-controlled on / off command. The physical switch signal refers to a signal triggered when a preset physical switch is turned on or off.

[0075] The software feedback signal, the time trigger signal, the voice signal, and the physical switch signal are all used to instruct the switching circuit 2021 to perform a power-on operation or a power-off operation, wherein the power-on operation includes: when the external AC power 10 is connected, powering on the entire sample analyzer, and sending a power-on instruction to the controller of the sample analyzer to instruct the controller to perform a power-on self-check maintenance operation;

[0076] The shutdown operation includes: sending a shutdown maintenance instruction to the controller to instruct the controller to perform a shutdown maintenance operation; if it is determined that the shutdown maintenance operation is completed, then powering off all or part of the loads 50 to be powered of the sample analyzer.

[0077] It should be noted that by setting the above-mentioned software feedback signal, time trigger signal, voice signal, and physical switch signal, the sample analyzer can be turned on and off by software (turning it on and off through software), timed on and off, voice-controlled on and off, and physical on and off.

[0078] It should also be noted that the precondition for executing the power-on operation is that the sample analyzer is in a soft-off state, that is, all or part of the loads 50 to be powered are powered off. When the sample analyzer is in a soft-off state, the main power switch is in an on state, that is, the power module 20 has been connected to the external AC power 10. Then, in the case of detecting or receiving the above control signal, the power module 20 powers on the entire sample analyzer and sends a power-on instruction to the controller to instruct the controller to perform a power-on self-test maintenance operation, thereby realizing the power-on control of the sample analyzer.

[0079] Furthermore, by sending a power-on command to the controller to instruct the controller to perform a power-on self-test maintenance operation, the sample analyzer can automatically perform a power-on self-test maintenance operation after being powered on, which is convenient for the user to use directly afterwards. Among them, the power-on self-test maintenance operation includes structural initialization, cleaning of pipelines and detection components, and preheating of components such as the reaction unit.

[0080] It should also be noted that by instructing the controller to perform shutdown maintenance operations before shutting down and cutting off the power, the adverse effects of direct power outage on the various loads 50 to be powered in the sample analyzer can be avoided, thereby ensuring the service life of the sample analyzer. In addition, the sample analyzer supports two shutdown modes: powering off all loads 50 to be powered and powering off some loads 50 to be powered, so that it can better adapt to different application scenarios. For example: for a sample analyzer with a reagent compartment, since the reagent compartment needs to be kept cold continuously, the remaining loads 50 to be powered except the reagent compartment can be powered off to ensure continuous power supply to the reagent compartment, etc.

[0081] It is worth mentioning that shutdown maintenance operations include probe maintenance, full pipeline cleaning, detection pool cleaning, etc. By shutting down the sample analyzer for maintenance before power failure, it is possible to avoid component damage caused by sudden power failure, effectively ensuring the service life of the sample analyzer.

[0082] It is also worth mentioning that by powering off all or part of the loads 50 to be powered of the sample analyzer, different application scenarios can be better adapted. For example, for a sample analyzer with a load 50 to be powered that requires continuous power supply, the remaining functional modules except the load 50 to be powered can be powered off. For a sample analyzer without a load 50 to be powered that requires continuous power supply, all the loads 50 to be powered of the sample analyzer can be powered off.

[0083] In addition, the sample analyzer provided by the present invention supports two shutdown modes: powering off all loads 50 to be powered and powering off some loads 50 to be powered. The user can set the corresponding shutdown mode according to actual needs. Moreover, assuming that some loads 50 to be powered need to be powered off, the loads 50 to be powered that need to be powered off and the loads 50 to be powered that do not need to be powered off can be set according to actual needs.

[0084] It can be understood that, through the above-mentioned power-off operation, the service life of each load 50 to be powered of the sample analyzer can be effectively guaranteed, and the aging problem of components caused by long-term power supply can be avoided.

[0085] In some embodiments, the switching circuit 2021 is used to perform the power-on operation when the on signal of the virtual switch is detected, wherein the power-on of the sample analyzer is completed by controlling all the target switches to be turned on;

[0086] Furthermore, when a closing signal of the virtual switch is detected, the shutdown operation is performed, wherein the power-off operation of all or part of the loads 50 to be powered is completed by controlling the on / off state of the target switch.

[0087] It should be noted that the virtual switch is more flexible and easier for users to operate. The virtual switch can be set on the user's terminal device or on the display interface of the sample analyzer. The user can power on / off all or part of the loads 50 to be powered by turning on or off the virtual switch.

[0088] In some embodiments, the time trigger signal includes a timed power-on signal and a timed power-off signal, the timed power-on signal is used to instruct the switching circuit 2021 to perform the power-on operation, and the timed power-off signal is used to instruct the switching circuit 2021 to perform the power-off operation.

[0089] In some embodiments, before sending the shutdown maintenance instruction to the controller, it also includes: popping up a first target pop-up window on a preset terminal device to prompt the user to confirm whether to perform a shutdown operation; if a confirmation shutdown instruction is received, sending the shutdown maintenance instruction to the controller.

[0090] It should be noted that, through the operation of popping up the first target pop-up window, it is possible to avoid the shutdown being triggered by mistake, such as the user accidentally turning off the virtual switch. In addition, if the user sets a scheduled shutdown time, and the sample analyzer is not completed when the scheduled shutdown time is reached, the shutdown operation can be canceled by clicking or touching the cancel button in the first target pop-up window, which is suitable for different usage scenarios of users and fully meets user needs. The terminal device can be the user's mobile terminal, computer terminal, or the display of the sample analyzer.

[0091] In some embodiments, the triggering condition for the confirmation shutdown instruction is detecting a user's confirmation shutdown operation or not detecting a user operation within a first preset time period.

[0092] It should be noted that by setting the above trigger conditions, it is possible to effectively avoid situations such as false shutdown triggering, and it is convenient for users to change the preset shutdown plan.

[0093] In some embodiments, the shutdown maintenance operation includes at least one shutdown maintenance item, and the shutdown maintenance item in the shutdown maintenance operation is determined based on the time of the last maintenance of the sample analyzer.

[0094] It should be noted that the complexity of the shutdown maintenance operation depends on the time of the last maintenance of the sample analyzer. If the time of the last maintenance of the sample analyzer is closer to the current time, the complexity of the shutdown maintenance operation is lower, and if the time of the last maintenance of the sample analyzer is farther from the current time, the complexity of the shutdown maintenance operation is higher. It can be understood that the lower the complexity of the shutdown maintenance operation, the fewer and simpler the shutdown maintenance items are, and the higher the complexity of the shutdown maintenance operation, the more and more complicated the shutdown maintenance items are.

[0095] In some embodiments, the complexity of the shutdown maintenance operation can be divided into N levels according to the difference between the time of the last maintenance of the sample analyzer and the current time, and different differences correspond to different levels, and each level corresponds to a corresponding shutdown maintenance item. For example: if the sample analyzer has just completed cleaning and maintenance, the shutdown maintenance operation can be simplified; if the sample analyzer has not been maintained for a long time, a complete maintenance sequence such as probe maintenance, full pipeline cleaning, and detection pool cleaning needs to be performed.

[0096] Through the above method, shutdown maintenance operations of different complexity can be performed according to different situations, with high flexibility and strong adaptability.

[0097] In some embodiments, the power-on self-test maintenance operation includes at least one power-on maintenance item, and the power-on maintenance item in the power-on self-test maintenance operation is determined based on the shutdown duration of the sample analyzer.

[0098] It should be noted that the complexity of the power-on self-test maintenance operation can be divided into M levels according to the shutdown time of the sample analyzer, and each level corresponds to a different complexity of the power-on self-test maintenance operation, thereby achieving a more flexible power-on self-test maintenance.

[0099] In some embodiments, before sending the shutdown maintenance instruction to the controller of the sample analyzer, it also includes: determining that the entire sample analyzer is in a ready state, where the ready state means that all loads 50 to be powered of the sample analyzer are powered on, in an idle state and have no faults.

[0100] It should be noted that the ready state means that all components of the sample analyzer are powered on, in an idle state and without faults, and the sample analyzer is not in a dormant state. By ensuring that the entire sample analyzer is in a ready state before sending a shutdown maintenance command to the controller of the sample analyzer, it is possible to avoid shutdown maintenance in the event of a functional module failure. It is understandable that under some hard faults, the instrument cannot perform the preset maintenance actions, and shutdown may cause contamination of the pipeline or damage to components.

[0101] In some embodiments, if the main power switch is in the off state, the sample analyzer is in a fully shut down state;

[0102] In the case where there are multiple target switches and the sample analyzer is in a fully powered-off state, if the switching circuit 2021 detects the turn-on signal of the main power switch and receives a control signal for instructing to perform a power-on operation, the multiple target switches are opened or turned on in sequence according to a preset power-on sequence to power on the multiple loads 50 to be powered in sequence.

[0103] The above embodiment can avoid power fluctuation and peripheral damage caused by power mutation by powering on each load 50 to be powered in sequence according to a preset power-on sequence, and facilitate power consumption control during power-on. After powering on each load 50 to be powered, the corresponding power-on self-test maintenance operation is performed to make the sample analyzer ready.

[0104] In some embodiments, if the switching circuit 2021 in the power module 20 is divided into different boards according to the different functions of the load 50, it can be divided into a digital power board, an analog power board, and a power supply board, etc. The digital power board is used to power the digital chip, MCU (Microcontroller Unit), core board, display screen, and optical coupler of the sample analyzer. The analog power board is used to power various signal detection circuits, sensors, etc. The power supply board is used to power various power devices and drivers such as motors, pumps, valves, fans, cooling sheets, heating films, etc. In the specific implementation process, the digital power board, the analog power board, and the power supply board can be powered on in sequence to avoid power mutations.

[0105] It should be mentioned that in the specific implementation process, corresponding startup, shutdown, and sleep control strategies can be set according to actual needs to adapt to different usage scenarios, such as adapting to users with different usage frequencies.

[0106] In some embodiments, the power management system can also be applied to multi-power systems and cascade systems, etc.

[0107] Please refer to Figure 2 In some embodiments, the power management module 40 further includes at least one control switch 402, the control switch 402 corresponds to the load 50 to be powered, and the control switch 402 is arranged between the DC / DC converter 401 and the corresponding load 50 to be powered;

[0108] When the control switch 402 is turned on, the connection channel between the DC / DC converter 401 and the corresponding load 50 to be powered is turned on; when the control switch 402 is turned off, the connection channel between the DC / DC converter 401 and the corresponding load 50 to be powered is turned off.

[0109] It should be noted that by setting a control switch 402 between the DC / DC converter 401 and the load 50 to be powered, it is possible to perform further and more precise on-off control of each load 50 to be powered. It can be understood that one or more loads 50 to be powered are connected to the DC / DC converter 401. The output of an AC / DC converter 2022 outputs multiple DC powers through multiple DC / DC converters 401 to power multiple loads 50 to be powered connected thereto; a DC / DC output can power multiple loads of the same power supply type (such as multiple valves and multiple pumps of the power type); multiple DC / DC outputs DC powers of different power supply types to power loads.

[0110] By providing a control switch 402 between the DC / DC converter 401 and each load 50 to be powered, the control switch 402 can be controlled to further control the on and off of each load 50 to be powered.

[0111] In the above embodiments, opening the switch means putting the switch in an on state, and closing the switch means putting the switch in an off state.
