DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the specific embodiments, see Figure 1, is a structural diagram of a power supply system in the first embodiment of the present application, the power supply system includes: a capacitor energy storage module 102, a relay module 103 and a main control module 104; the input end of the capacitor energy storage module 102 is connected to the power supply 105 of the external device, the input end of the relay module 103 is connected to the output end of the capacitor energy storage module 102, the output end of the main control module 104 and the power supply 105, and the output end of the relay module 103 is connected to the input end of the main control module 104; the main control module 104 is used to send a first conduction signal to the relay module 103; the first conduction signal is used to instruct the relay module 103 to conduct the power supply 105 and the main control module 104; the relay module 103 is used to receive the first conduction signal and generate a first high level; The first high level is used to connect the power supply 105, the relay module 103 and the main control module 104 to generate a first path; the power supply 105 is used to supply power to the capacitor energy storage module 102, and to supply power to the main control module 104 through the first path; the main control module 104 is used to send a second conduction signal to the relay module 103; the second conduction signal is used to instruct the relay module 103 to conduct the capacitor energy storage module 102 and the main control module 104; the relay module 103 is also used to receive the second conduction signal and generate a second high level; the second high level is used to connect the capacitor energy storage module 102, the relay module 103 and the main control module 104 to generate a second path; the capacitor energy storage module 102 is used to supply power to the main control module 104 through the second path.

[0029] Specifically, when the power supply 105 can provide enough voltage, the power supply 105 supplies power to the capacitor energy storage module 102, so that the capacitor energy storage module 102 stores energy; the main control module 104 sends a first conduction signal to the relay module 103, and the relay module 103 receives the first conduction signal to generate a first high level, so that the power supply 105 is connected to the main control module 104, and a first path connecting the power supply 105, the relay module 103 and the main control module 104 is generated, and the power supply 105 supplies power to the main control module 104 through the first path. When the power supply 105 cannot provide enough voltage, the main control module 104 sends a second conduction signal to the relay module 103, and the relay module 103 receives the second conduction signal to generate a second high level, so that the capacitor energy storage module 102, the relay module 103 and the main control module 104 are connected to generate a second path, and the capacitor energy storage module 102 supplies power to the main control module 104 through the second path, so as to ensure that the main control module 104 can work normally when the voltage of the power supply 105 is insufficient, such as saving the data in the main control module. Specifically, the capacitor energy storage module 102 may be a capacitor capable of storing energy, such as a farad capacitor. The farad capacitor is small in size and large in capacity, and is convenient for supplying power to the medical device when the power is off, so as to facilitate the use of the medical device.

[0030] In the specific embodiments, see Figure 2The system further comprises a switch module 101, the input end of the switch module 101 is connected to the output end of the relay module 103 and the power supply 105 of the peripheral device, the output end of the switch module 101 is connected to the input end of the main control module 104, and the switch module 101 is used to receive the second high level to make the power supply 105 of the peripheral device conduct with the main control module 104. Specifically, when the power is cut off unexpectedly, the power disappears, and the farad capacitor supplies power to the main control module at this time. The main control module detects the unexpected power off and immediately saves the data configuration. In this process, the power of the farad capacitor is consumed. After saving, the second path is disconnected, thereby avoiding excessive consumption of the power in the farad capacitor; when the key of the switch module is manually pressed, the signal is fed back to the D trigger through the key circuit, and the CLK of the D trigger generates a rising edge at this time, and the power enable pin of the main control module outputs a high level, thereby opening the power path, and the power supply is connected. In response to the manual operation, the relevant instrument will be directly turned on and restored to the state before the power off.

[0031] In the specific embodiments, see Figure 3 , the first pin of the relay module 103 is respectively connected to the power supply 105, the fifth pin of the relay module 103 and grounded; the eighth pin and the seventh pin of the relay module 103 are connected to the main control module 104; the third pin of the relay module 103 is connected to the capacitor energy storage module 102; the second pin of the relay module 103 is connected to the power enable pin of the main control module 104; the tenth pin of the relay module 103 is respectively connected to the capacitor energy storage module 102, the sixth pin of the relay module 103 and the control pin of the main control module 104. Specifically, a diode D1 is provided between the fifth pin of the relay module 103 and the first pin of the relay module 103, which is connected from the fifth pin to the first pin; a diode D2 is provided between the sixth pin of the relay module 103 and the tenth pin of the relay module 103, which is connected from the sixth pin to the tenth pin; and a diode D4 is provided between the second pin of the relay module 103 and the main control module 104, which is connected from the second pin to the main control module 104.

[0032] Specifically, VF_+5V5 is the capacitor energy storage module 102, 5V_C is the power supply 105, PWR_EN is the power enable pin of the main control module 104, MCU_CLOSE is the control pin of the main control module 104, and MCU_CLOSE is at a low level by default. The relay module 103 can control the closing direction of COM1 and COM2 by controlling the two coils NO and NC. When NO is closed, COM1 is closed with NO1, COM2 is closed with NO2, and NO and NC are mutually exclusive and cannot be closed at the same time. When the power supply 105 is powered normally, 5V_C exists, MCU_CLOSE is pulled low by default, and NO is closed at this time, and the power supply 105 supplies power to the main control module 104 normally. When the power supply 105 cannot supply power normally, COM1 is closed with NC1, COM2 is closed with NC2, and the capacitor energy storage module supplies power to the main control module, thereby ensuring the normal operation of the main control module, such as saving data in the main control module.

[0033] Specifically, when the power is cut off unexpectedly, the power disappears. At this time, the farad capacitor supplies power to the main control. The main control module detects the unexpected power off and immediately saves the data configuration. In this process, the power of the farad capacitor is consumed. After saving, let MCU_CLOSE output a high level. At this time, 5V_C disappears, MCU_CLOSE is high, then NC is closed, the first path is controlled to be disconnected, and the main control module is powered off. At this time, because the power supply circuit is disconnected, the power of the farad capacitor will no longer be consumed. The second path is controlled to be turned on, and the farad capacitor supplies power to PWR_EN. This design has an advantage. After the power is completely cut off, the remaining power of the farad capacitor will supply power to PWR_EN of the D flip-flop. At this time, PWR_EN is at a high level. When the power is reconnected, because PWR_EN is already at a high level, it does not need to pass through the key circuit. At this time, the switch module is already in the on state, and the relevant instruments will automatically start up directly and restore to the state before the power failure. This application utilizes the characteristics of the magnetic relay. After the main control module is completely powered off, neither NO nor NC has a high level, and ordinary relays should not be able to close. However, the characteristic of the magnetic relay is that even if the power is off, it will be attracted by the magnetic coil, thereby maintaining the previous state. Therefore, after the power is completely cut off, the first path is still disconnected and the second path is controlled to be turned on, so the farad capacitor can continue to supply power to PWR_EN and realize automatic power-on of related instruments.

[0034] In the specific embodiments, see Figure 4 The power supply system further includes a first conduction module 106; one end of the first conduction module 106 is connected to the main control module 104, and the other end of the first conduction module 106 is connected to the capacitor energy storage module 102; the first conduction module is used to conduct the main control module 104 with the capacitor energy storage module 102. By setting the first conduction module, the voltage in the capacitor energy storage module 102 is conducted to the main control module 104 in a single phase.

[0035] In the specific embodiments, see Figure 2 , the first conduction module 106 includes a first diode D3, a first resistor R1, a second resistor R2 and a MOS tube P1; the drain of the MOS tube P1 is connected to the sixth pin of the relay module 103 and the tenth pin of the relay module 103; the source of the MOS tube P1 is connected to the positive electrode of the first diode D3; the negative electrode of the first diode D3 is connected to the drain of the MOS tube P1, and the gate of the MOS tube P1 is connected to one end of the first resistor R1 and one end of the second resistor R2; the other end of the first resistor R1 is connected to the control pin of the main control module 104; the other end of the second resistor R2 is connected to the source of the MOS tube P1 and grounded. The first resistor R1 and the second resistor R2 are used for voltage stabilization, and the MOS tube P1 is used to control the conduction and closing of the main control module 104 and the relay module 103, so that the voltage in the capacitor energy storage module 102 is single-phase conducted to the main control module 104.

[0036] In the specific embodiments, see Figure 5 The power supply system further includes: an analog-to-digital conversion module 201; the input end of the analog-to-digital conversion module 201 is connected to the output end of the relay module 103, and the output end of the analog-to-digital conversion module 201 is connected to the input end of the main control module 104; the analog-to-digital conversion module 201 is used to receive the analog voltage sent by the relay module 103, convert the analog voltage into a digital voltage, and then send it to the main control module 104. By setting the analog-to-digital conversion module 201, the main control module 104 converts the analog voltage sent by the power supply 105 into a digital voltage that can be recognized by the main control module 104, so that when the voltage sent by the power supply 105 does not reach the working voltage of the main control module 104, the main control module 104 can send the second conduction signal in time to ensure that the capacitor energy storage module 102 supplies power to the main control module 104 in time.

[0037] In the specific embodiments, see Figure 6 , the power supply system also includes: a step-down module 301; the input end of the step-down module 301 is connected to the output end of the relay module 103, and the output end of the step-down module 301 is connected to the input end of the main control module 104; the step-down module 301 is used to receive the voltage sent by the power supply 105, and send the stepped-down voltage; the main control module 104 is used to receive the stepped-down voltage to realize power supply to the main control module 104. Specifically, the voltage sent by the power supply 105 is usually 220V, and the working voltage of the main control module 104 is 15V, so the step-down module 301 is set to step down the voltage sent by the power supply 105, so as to ensure the normal operation of the main control module 104.

[0038] In the specific embodiments, see Figure 7The power supply system further includes: a filter module 401; the input end of the filter module 401 is connected to the output end of the relay module 103, and the output end of the filter module 401 is connected to the input end of the main control module 104; the filter module 401 is used to receive the voltage sent by the power supply 105, and send the filtered voltage; the main control module 104 is used to receive the filtered voltage to realize power supply to the main control module 104. By setting the filter module 401 to filter the voltage sent by the power supply 105, the stability of the voltage received by the main control module 104 is guaranteed, and the stability of the operation of the main control module 104 is improved.

[0039] In the specific embodiments, see Figure 8 The power supply system further includes: a data storage module 501; the input end of the data storage module 501 is connected to the output end of the main control module 104; the main control module 104 is also used to send storage instructions and storage data in the main control module 104 to the data storage module 501; the data storage module 501 is used to receive storage instructions and storage data to complete the storage of the storage data in the main control module 104. Specifically, when the power supply 105 module fails to supply power to the main control module 104 normally, the storage data in the main control module 104 will be lost. By setting the data storage module 501, the data storage module 501 stores the storage data in the main control module 104 in real time, thereby ensuring that the storage data in the main control module 104 is completely saved.

[0040] In a specific embodiment, the relay module 103 includes a bidirectional magnetic relay. The bidirectional magnetic relay can more accurately control the conduction and disconnection of the first path and the second path, and provide stability for the operation of the main control module 104.
