Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a schematic structural diagram of a power management system according to an embodiment of the present invention, which is applicable to a case of managing power.
Referring to fig. 1, the specific structure of the power management apparatus includes: a power supply module 10, a load 20, a switch control module 40, a discharge module 30, and a switch detection module 50; wherein, the liquid crystal display device comprises a liquid crystal display device,
a power module 10 including a first end and a second end; a load 20 comprising a first end and a second end; a first end of the load 20 is electrically connected to a first end of the power module 10, and a second end of the load 20 is electrically connected to a second end of the power module 10; a discharge module 30 including a control end, a first end, and a second end; a first end of the discharging module 30 is electrically connected with a first end of the load 20, and a second end of the discharging module 30 is electrically connected with a second end of the power module 10; the discharging module 30 is used for responding to the switch control signal received by the control end thereof to turn on or off; a switch control module 40 comprising an input and a first output; an input end of the switch control module 40 is electrically connected with the first end of the load 20, and a first output end of the switch control module 40 is electrically connected with a control end of the discharge module 30; the switch control module 40 is configured to obtain a load voltage across the load 20, and generate a first switch control signal of the discharge module 30 based on the load voltage; the switch detection module 50 comprises an output end; the output end of the switch detection module 50 is electrically connected with the switch control module 40; the switch detection module 50 is configured to detect a switch state of the power module 10, and output the switch state to the switch control module 40, so that the first output terminal of the switch control module 40 outputs the second switch control signal of the discharge module 30 based on the switch state.
Specifically, the technical scheme in the embodiment of the invention can be that the power supply for supplying power to the surgical robot is managed. Accordingly, the load 20 in this embodiment can be understood as a surgical robot. In the prior art, when the load 20 is changed, that is, the state of the power supply is changed, during the process of supplying power to the load 20 or charging the power supply, a voltage fluctuation problem in the power supply circuit occurs; for example, the motor of the power supply is in a power generation state, which causes a problem of a rise in system voltage, and the power supply device in the prior art cannot solve the problem, thereby bringing about a safety hazard of damaging equipment.
Therefore, in order to solve the above-mentioned problems, the technical solution of the present embodiment is to detect the switching state of the power module 10 based on the switching detection module 50. If the switch detection module 50 detects that the switch of the power module 10 is in the on state, the load voltage across the load 20 is further obtained based on the switch control module 40. Further, the switch control monitors the obtained load voltage in terms of voltage data. If the obtained load voltage is detected to exceed the first voltage threshold, a corresponding first switch control signal is output to the discharging module 30. At this time, the first switch control signal is used to control the switch of the discharging module 30 to conduct. When receiving the first switch control signal, the control end of the discharging module 30 responds to the first switch control signal to keep the switch in the discharging module 30 on, so that energy exceeding the threshold voltage is consumed, and the rising voltage is reduced to a normal value range.
The first voltage threshold in this embodiment may include a voltage value greater than the rated voltage of the load 20, or may be another voltage value, which is not limited in this embodiment.
Conversely, if the obtained load voltage is detected not to exceed the first voltage threshold, a corresponding first switch control signal is output to the discharging module 30. At this time, the first switch control signal is used to control the switch of the discharging module 30 to be turned off. The control terminal of the discharging module 30 responds to the first switch control signal when receiving the first switch control signal, and keeps the switch in the discharging module 30 open so that the energy provided by the power supply supports the load 20 to operate. Based on the technical scheme, the problem that when the state of a power supply changes, particularly when motor equipment is in a power generation state, equipment can be damaged due to the fact that the voltage of the system is increased is solved.
Optionally, if the switch detection module 50 detects that the switch of the power module 10 is in the off state, a state signal of the switch in the off state is sent to the switch control module 40, and the switch control module 40 generates a corresponding second switch control signal to the discharge module 30 based on the signal state. At this time, the second switch control signal is used to control the switch of the discharging module 30 to conduct. When the control end of the discharging module 30 receives the second switch control signal, the switch in the discharging module 30 is kept on in response to the second switch control signal, so that the residual charge of the load 20 is rapidly consumed by the discharging module 30, that is, the load voltage is rapidly reduced to zero after the power supply is powered off. Thus solving the problem of slower voltage drop of the load 20 after the power supply is powered down.
The power management system provided by the embodiment of the invention comprises a power module 10, a load 20, a switch control module 40, a discharging module 30 and a switch detection module 50; the following procedure may be implemented: if the obtained load voltage is detected to exceed the first voltage threshold, a corresponding first switch control signal is output to the discharging module 30. When receiving the first switch control signal, the control end of the discharging module 30 responds to the first switch control signal to keep the switch in the discharging module 30 on, so that energy exceeding the threshold voltage is consumed, and the rising voltage is reduced to a normal value range. And, if the switch detection module 50 detects that the switch of the power module 10 is in the off state, a state signal of the switch in the off state is sent to the switch control module 40, and the switch control module 40 may generate a corresponding second switch control signal to the discharge module 30 based on the signal state. When the control end of the discharging module 30 receives the second switch control signal, the switch in the discharging module 30 is kept on in response to the second switch control signal, so that the residual charge of the load 20 is rapidly consumed by the discharging module 30, that is, the load voltage is rapidly reduced to zero after the power supply is powered off. Based on the technical scheme, the problem that the load voltage drops slowly after the instantaneous current of the system is overlarge and the power supply is powered off is solved, and the damage degree of equipment is reduced.
In the embodiment of the present invention, in the implementation process of the technical solution of fig. 1, in the process that the switch detection module 50 detects that the switch state of the power module 10 is changed from the off state to the on state, that is, in the process that the power is powered on, the power directly supplies power to the load 20, which can cause the excessive instantaneous current of the power system and damage the power. Based on the above technical problems, the power management system of the present embodiment is further provided with a switch module 60 and a current limiting module 70.

Specifically, the switch detection module 50 detects the load voltage across the load 20 during the process of detecting that the switching state of the power module 10 is changed from the off state to the on state. If the switch detection module 50 detects that the voltage value of the load voltage is greater than the second voltage threshold, a corresponding third switch control signal is output to the switch module 60. When the control end of the switch module 60 receives the third switch control signal, the switch in the switch module 60 is kept off in response to the third switch control signal, so that the power module 10 can only charge and supply power to the load 20 through the current limiting module 70, and the problem of overlarge current at the moment of conducting the power switch 120 is avoided.
The second voltage threshold in this embodiment may be two-thirds of the rated voltage of the load 20, or may be another voltage value, which is not limited in this embodiment. The current of the current limiting module 70 may be controlled according to historical experience, for example, a power resistor with preset ohms is used as the current limiting module 70 to implement the above technical solution, the current limiting module 70 may also be formed by a transistor, and the current limiting module 70 may also be formed based on other manners, which is not limited in this embodiment.
