In an alternative embodiment, the energy storage module 210 may be a lithium battery module or a capacitor.
In the case where the medical vehicle-mounted device 1 is in a different state, power is supplied through the first power supply path 100 and/or the second power supply path 200. The state of the medical vehicle-mounted device 1 includes various kinds, for example: the medical vehicle-mounted equipment 1 is in a power-off state, and the power supply device 10 is not required to supply power in the power-off state; the medical vehicle-mounted device 1 is in a standby state or in a scanning (operating) state, both of which require power supply by the power supply means 10. When the medical vehicle-mounted device 1 is in different states, power supply through different power supply paths may be selected, power supply may be performed only through the first power supply path 100, power supply may be performed only through the second power supply path 200, or power supply may be performed through both the first power supply path 100 and the second power supply path 200.
The power supply device 10 provided by the embodiment of the application is applied to the medical vehicle-mounted equipment 1, and the power supply device 10 comprises a first power supply path 100 and a second power supply path 200; the first power supply path 100 comprises a rectification module 110 and an inversion module 120 which are connected in sequence, and the alternating current power grid 11 supplies power to the medical vehicle-mounted equipment 1 through the rectification module 110 and the inversion module 120; the second power supply path 200 includes an energy storage module 210 and an inverter module 120 that are connected in sequence, and the energy storage module 210 and the inverter module 120 supply power to the medical vehicle-mounted device 1. In the case where the medical vehicle-mounted device 1 is in a different state, power is supplied through the first power supply path 100 and/or the second power supply path 200. The power supply device 10 provided in this embodiment provides two power supply paths, and a user can flexibly select different power supply paths to supply power according to an actual application scenario and different states of the medical vehicle-mounted device 1. That is, the power supply device 10 provided in the present embodiment is suitable for different application scenarios and different states of the medical vehicle-mounted device 1, and has high applicability and flexibility.
In one embodiment, as shown in fig. 2, the power supply apparatus 10 further includes a control module 300, and the control module 300 is configured to supply power to the medical vehicle-mounted device 1 through the first power supply path 100 based on the ac power grid 11 when the medical vehicle-mounted device 1 is in a standby state.
When the state of the medical vehicle-mounted device 1 is the standby state, the first power feeding path 100 in the power feeding device 10 is used to feed power to the medical vehicle-mounted device 1. When the control module 300 determines that the state of the medical vehicle-mounted device 1 is the standby state, the first power supply path 100 in the power supply device 10 is controlled to be conducted, that is, the ac power grid 11 is connected, and the electric energy provided by the ac power grid 11 can be transmitted to the medical vehicle-mounted device 1 through the rectifier module 110 and the inverter module 120 in the first power supply path 100, so as to supply power to the medical vehicle-mounted device 1.
In one embodiment, the control module 300 determines the state of the medical onboard apparatus 1 by determining the operating power of the medical onboard apparatus 1. Different states of the medical vehicle-mounted device 1 correspond to different power thresholds. The power supply device 10 includes a current sensor and a voltage sensor, both of which are disposed on the medical vehicle-mounted device, and both of which are connected to the control module 300. The control module 300 may include a Micro Controller Unit (MCU). The current sensor is used for detecting a current value of the medical vehicle-mounted apparatus 1 during operation and transmitting the current value to the control module 300, and the voltage sensor is used for detecting a voltage value of the medical vehicle-mounted apparatus 1 during operation and transmitting the voltage value to the control module 300. After receiving the current detected by the current sensor and the voltage detected by the voltage sensor, the control module 300 calculates the power of the medical vehicle-mounted device 1 during operation according to the current value and the voltage value, and determines the state of the medical vehicle-mounted device 1 according to the power. Specifically, the control module 300 compares the power with power thresholds corresponding to different states of the medical vehicle-mounted apparatus 1 to determine the state of the medical vehicle-mounted apparatus 1. For example, the power threshold value when the medical vehicle-mounted device 1 is in the standby state is a first power threshold value; the power threshold value of the medical vehicle-mounted device 1 in the working state is a second power threshold value, and the second power threshold value is larger than the first power threshold value. The MCU compares the calculated power with a first power threshold and a second power threshold, and if the power reaches the first power threshold, the medical vehicle-mounted equipment 1 is in a standby state; if the power reaches the second power threshold, the medical vehicle-mounted device 1 is in the working state. Wherein the first power threshold and the second power threshold may be a power range.
In the present embodiment, when the medical vehicle-mounted device 1 is in the standby state, the required power is small, and the electric power required in the standby state of the medical vehicle-mounted device 1 can be satisfied only by supplying power using the first power supply path 100. When the medical vehicle-mounted device 1 is in the standby state, the control module 300 only controls the first power supply path 100 to be conducted, so that the first power supply path 100 is only used for supplying power to the medical vehicle-mounted device 1, the second power supply path 200 is not needed for supplying power, the service life of the energy storage module 210 in the second power supply path 200 can be prolonged, and the practicability of the power supply device 10 is improved.
With continued reference to fig. 2, in an embodiment, the power supply apparatus 10 further includes a switch 310, and the switch 310 is connected between the energy storage module 210 and the inverter module 120. The on/off of the switch 310 can control the on/off of the energy storage module 210 and the inverter module 120. The switch 310 may be a push button switch, and may be a smart switch. The present embodiment does not limit the specific structure of the switch 310 as long as the function thereof can be achieved.
In one embodiment, the control module 300 is specifically configured to control the switch 310 to be opened to supply power to the medical vehicle-mounted device 1 through the first power supply path 100 based on the ac power grid 11 when the medical vehicle-mounted device 1 is in a standby state.
The first power supply path 100 and the second power supply path 200 share the inverter module 120, and when the medical vehicle-mounted device 1 is in a standby state, the control module 300 sends a control signal to the switch 310 to control the switch 310 to be disconnected, so that the connection between the energy storage module 210 and the inverter module 120 can be disconnected, that is, the second power supply path 200 is disconnected, and only the first power supply path 100 is used for supplying power to the medical vehicle-mounted device 1.
In this embodiment, the switch 310 is disposed between the energy storage module 210 and the inverter module 120 to select the first power supply path 100 and the second power supply path 200, and the power supply apparatus 10 has a simple structure and is easy to implement. Further, the control module 300 controls the method of supplying power to the medical vehicle-mounted device 1 by using only the first power supply path 100 by controlling the on/off of the switch 310, simply and quickly.
In one embodiment, the control module 300 is further configured to charge the energy storage module 210 through the rectification module 110 based on the ac power grid 11 when the medical vehicle-mounted device 1 is in the standby state.
The energy storage module 210 includes a first terminal and a second terminal, the first terminal of the energy storage module 210 is connected to the third terminal of the inverter module 120 through the switch 310, and the second terminal of the energy storage module 210 is connected to the second terminal of the rectifier module 110. Under the condition that the medical vehicle-mounted device 1 is in a standby state, the alternating current provided by the alternating current grid 11 is input to the rectifying module 110, the rectifying module 110 converts the received alternating current into direct current, one part of the direct current supplies power to the medical vehicle-mounted device 1 through the inverter module 120, and the other part of the direct current is input to the energy storage module 210 to charge the energy storage module 210. That is, when the medical vehicle-mounted device 1 is in the standby state, the energy storage module 210 does not discharge, a part of the electric energy provided by the ac power grid 11 is used for supporting the operation of the medical vehicle-mounted device 1, and another part of the electric energy is used for charging the energy storage module 210.
In the present embodiment, the ac power grid 11 is charged to the energy storage module 210 through the rectifier module 110 while the ac power grid 11 supplies power to the medical vehicle-mounted device 1 through the first power supply path 100, so that the ac power grid 11 can be sufficiently utilized, and the power is supplied to the medical vehicle-mounted device 1 while charging, so that the charging waiting time does not need to be set, and the practicability of the power supply module 10 can be improved. The charging time and the discharging time of the energy storage module 210 are limited differently in this embodiment, as long as the energy storage module 210 can be ensured not to feed power, and the power can be normally supplied to the medical vehicle-mounted device 1.
In an alternative embodiment, during one scanning cycle of the medical vehicle-mounted device, i.e. during the time when the medical vehicle-mounted device is in the standby state and the operating state, the charging amount and the discharging amount of the energy storage module 210 achieve dynamic balance, so that the energy storage module 210 does not feed power and can normally supply power to the medical vehicle-mounted device 1.
In an alternative embodiment, a first switch is disposed between the rectifying module 110 and the energy storage module 210, that is, the first switch is connected to the second end of the rectifying module 110 and the second end of the energy storage module 210. The control module 300 can control the on/off between the rectifier module 110 and the energy storage module 210 by controlling the on/off of the first switch.
Specifically, when the medical vehicle-mounted device 1 is in the standby state, the control module 300 controls the switch 310 to be opened, the first switch to be closed, so that the ac power grid 11 supplies power to the medical vehicle-mounted device 1 through the first power supply path 100, and the ac power grid 11 charges the energy storage module 210 through the rectification module 110.
In one embodiment, the control module 300 is further configured to control the switch 310 to be closed to supply power to the medical vehicle-mounted device 1 through the first power supply path 100 and the second power supply path 200 when the medical vehicle-mounted device 1 is in the working state. The power is supplied to the medical vehicle-mounted device 1 simultaneously using the first power supply path 100 and the second power supply path 200 in the power supply apparatus 10.
When the state of the medical vehicle-mounted device 1 is an operating state (exposure or scanning state), the operating power required for the medical vehicle-mounted device 1 is large as shown in fig. 3. In fig. 3, the abscissa indicates the operating state of the medical vehicle-mounted device 1, the ordinate indicates the charge-discharge state of the energy storage module 210, the broken line indicates the power supplied from the ac power grid 11 to the medical vehicle-mounted device 1, and the solid line indicates the power consumed by the medical vehicle-mounted device 1. As can be seen from fig. 3, in the case where the medical vehicle-mounted device 1 is in the standby state, the power consumed by the medical vehicle-mounted device 1 is small, and the power supplied from the ac power grid 11 to the medical vehicle-mounted device 1 can ensure the normal operation of the medical vehicle-mounted device 1 and can also charge the energy storage module 210. When the medical vehicle-mounted device 1 is in the operating state, the power consumed by the medical vehicle-mounted device 1 is large, and at this time, the energy storage module 210 discharges and supplies power to the medical vehicle-mounted device 1 while the alternating-current grid 11 supplies power to the medical vehicle-mounted device 1.
In this embodiment, when the medical vehicle-mounted device 1 is in an operating state, the first power supply path 100 and the second power supply path 200 in the power supply device 10 are used to simultaneously supply power to the medical vehicle-mounted device 1, so that power which is required by the medical vehicle-mounted device 1 and cannot be supplied only through the first power supply path 100 can be avoided, the use of electric energy in the energy storage module 210 can be saved, and the service life of the energy storage module 210 is prolonged. In addition, the high-power medical vehicle-mounted equipment 1 can be driven to work by using the small power of the alternating current power grid 11, and the applicability and the practicability of the power supply device 10 can be improved. And, the smaller alternating current power grid 11 power can reduce the line specification of the alternating current power grid 11, and the operation is convenient.
Referring to fig. 4, in an embodiment, the power supply apparatus 10 further includes a detection module 400, and the detection module 400 is configured to detect whether the ac power grid 11 is powered off and transmit a detection result to the control module 300.
The detection module 400 is in communication connection with the control module 300, and the detection module 400 can transmit the detection result to the control module 300. The detection result of the detection module 400 includes a power failure of the ac power grid 11 and a power failure of the ac power grid 11. The present embodiment does not limit the specific structure and the detection manner of the detection module 400, as long as the function thereof can be realized.
In an alternative embodiment, the detection module 400 is a current sensor, and the current sensor is disposed at the output end of the ac power grid 11, and if the current detected by the current sensor is zero, it indicates that the ac power grid 11 is powered off; if the current detected by the current sensor is not zero, it indicates that the ac grid 11 is not powered off. The detection module 400 may also be a voltage sensor, which is disposed at the output end of the ac power grid 11, and if the voltage detected by the voltage sensor is zero, it indicates that the ac power grid 11 is powered off; if the voltage detected by the voltage sensor is not zero, it indicates that the ac grid 11 is not powered off.
The control module 300 is configured to supply power to the medical vehicle-mounted device 1 through the second power supply path 200 when the received detection result indicates that the ac power grid 11 is powered off.
If the detection module 400 detects that the ac power grid 11 is powered off and sends a power-off result of the ac power grid 11 to the control module 300, the control module 300 controls the second power supply path 200 to be conducted so as to supply power to the medical vehicle-mounted device 1.
