Description

Technical Field

[0001] The present application relates to the technical field of pulse light therapy instruments, and in particular to a capacitor bank discharge method and system. Background Art

[0002] Intense Pulsed Light (IPL) consists of incoherent, non-parallel broad-spectrum light with a wavelength of usually 400nm-1200nm. It is generally released under high pressure from a high-energy flash lamp and can release high energy in a very short time (tens to hundreds of microseconds) in the form of light radiation. Based on the fact that intense pulsed light covers the main absorption peaks of multiple target chromophores in the skin (such as melanin, hemoglobin, and water, etc.), and that it has photothermal effects through high-intensity pulsed light, it is widely used in the medical field to treat skin diseases or dry eye syndrome.

[0003] In the process of using an intense pulsed light instrument for treatment, multiple beams of energy are generally output continuously. When the intense pulsed light instrument performs an energy output, the power supply charges the capacitor group, and the capacitor group discharges the pulse light source after storing energy, stimulating the pulse light source to output intense pulsed light. The capacitor group of the intense pulsed light instrument needs to store energy each time it performs energy output. Then the remaining power after the capacitor group discharges the pulse light source will definitely affect the next discharge effect.

[0046] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0047] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0048] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0049] In the prior art, during the process of an intense pulsed light instrument executing a pulsed light source to output a pulsed laser, the pulsed light source output energy is determined according to the user input requirements, and the charging power of the power supply to the capacitor group is calculated only based on the pulsed light source output energy. After the capacitor group stores energy, it discharges the pulsed light source to stimulate the pulsed light source to output laser. However, after the capacitor group discharges the pulsed light source last time, the state of the capacitor group is unknown, and the unknown state of the capacitor group will affect the next pulsed light source discharge effect. For example, if there is still residual power left in the capacitor group, but the next time the pulsed light source discharge process is executed, the power supply still charges the capacitor group according to the power required for treatment, causing the actual power of the capacitor group to not meet the next treatment requirement. On the other hand, if the power is turned off after the pulsed light source is discharged, the residual power of the capacitor group will also affect the safety of subsequent maintenance operations.

[0050] In view of the above problems, an embodiment of the present application proposes a capacitor group discharge method, which is applied to a capacitor group discharge system, and obtains the operation content to be performed next after the intense pulsed light instrument completes the current pulse light source output, determines the rated remaining power that should be stored in the capacitor group according to the operation content, discharges the capacitor group with the rated remaining power, and uses a voltage feedback module to monitor the voltage across the capacitor group during the discharge process, so as to determine whether the remaining power in the capacitor group meets the requirements of the next operation, thereby solving the problem of the next operation being affected by the unknown residual power in the capacitor group.

[0051] Figure 1 is a schematic diagram of the structure of a capacitor bank discharge system in an example of the present application, such as Figure 1 As shown, the capacitor group discharge system includes a calculation module, a voltage feedback module and a discharge resistance module; the voltage feedback module is connected to the capacitor group to monitor the voltage of the capacitor group; a second connection line is formed between the voltage feedback module and the calculation module, and the voltage feedback module sends the monitored voltage signal to the calculation module through the second connection line, so that the calculation module can adjust the control strategy according to the real-time power of the capacitor group and the power that the capacitor group should store, and the discharge resistance consumes the power of the capacitor group under a reasonable control strategy. Through the cooperation of the calculation module, the voltage feedback module and the discharge resistance module, the power change process of the capacitor group is obtained. If a display device is added, the power change process of the capacitor group can also be visualized, so that there is no need to rely on experience, and the power consumption value of the capacitor group can be completed. Reasonable values ​​and safe discharge of the capacitor group can be achieved.

[0052] Figure 2 FIG. 1 is a flowchart of the steps of executing a capacitor bank discharge method by a capacitor bank discharge system according to an embodiment of the present application. Figure 2 As shown, the steps include:

[0053] S210: After the current pulse light output program is executed, the calculation module obtains parameter information of the next operation input by the user.

[0054] The parameter information includes a signal for stopping the discharge of the pulse light source or a preset power corresponding to the next execution of the pulse light output program.

[0055] The signal for stopping the pulse light source discharge means: after outputting pulse laser N times, one stage of treatment is completed, and after the Nth execution of the current pulse light output program is completed, a signal for ending the pulse laser output program sent by the user is detected.

[0056] A signal for stopping the discharge of the pulse light source is detected, and the calculation module determines that there should be no residual electricity in the capacitor group after the capacitor group is discharged through the discharge resistor, so as to determine the discharge strategy of the discharge resistor module with the goal of ensuring that the capacitor group has no residual electricity.

[0057] The preset power corresponding to the next execution of the pulse light output program means that if one treatment requires N pulse laser outputs, after the execution of Ni pulse light output programs is completed, the pulse light output program needs to be continued to receive the preset power of the pulse light that needs to be output for the N-i+1th time input by the user, and the discharge strategy of the discharge resistance module is formulated based on the standard of reaching the preset power as quickly as possible.

[0058] S211: Determine, by the calculation module, the rated remaining power required by the capacitor bank for executing the next operation according to the parameter information.

[0059] S212: monitoring the real-time voltage of the capacitor group during the discharge process of the capacitor group through the voltage feedback module.

[0060] By monitoring the real-time voltage of the capacitor group, the discharge progress of the capacitor group can be detected and the discharge strategy can be adjusted in time.

[0061] S213: Calculate the real-time remaining power corresponding to the real-time voltage through the calculation module, calculate the difference between the real-time remaining power and the rated remaining power, and before the difference reaches the minimum, control the discharge resistance module to consume the power of the capacitor group.

[0062] In one example, the real-time voltage of the capacitor group can be collected every unit time through the voltage feedback module, and the calculation module calculates the real-time remaining power of the capacitor group. Before the real-time remaining power reaches the standard, the discharge resistor is controlled to operate. When the real-time remaining power does not reach the standard, the discharge is stopped in time to prevent the loss of the capacitor group caused by excessive discharge and save energy.

[0063] An embodiment of the present application provides an implementation method for determining the rated remaining power:

[0064] S2111: When the parameter information is a signal to stop the discharge of the pulse light source, it is determined that the rated remaining power is zero.

[0065] S2112: When the parameter information is a preset power corresponding to the next execution of the pulse light output program, the power corresponding to the preset power is calculated as the rated remaining power.

[0066] For example, assuming that the preset power is P, electric energy J is required to achieve the goal of exciting the pulse light source to output pulse light with a power of P, then the rated remaining power is J.

[0067] When the current pulse light output program is completed, the voltage of the capacitor group is detected through the voltage feedback module, and the calculation module detects the initial remaining power of the capacitor group at this time. If the initial remaining power is less than the rated remaining power, there is no need to discharge the capacitor group through the discharge resistor; further, the difference between the initial remaining power and the rated remaining power can be calculated. When the pulse light output program is executed next time, it is only necessary to supplement the difference power to the capacitor group through the power supply, so as to complete the charging of the capacitor group and reduce the consumption of electric energy.

[0068] For example, if the initial remaining power is Y and the rated remaining power is X+Y, then there is no need to discharge the capacitor bank using a discharge resistor. When the pulse light output program is executed next time, a charge X instruction is sent to the power module to control the power supply to charge X to the capacitor bank.

[0069] Based on the execution result of the above step S211, the sub-steps adopted in executing step S213 may be selected:

[0070] If the execution result of step S211 is that the rated remaining power is determined to be zero, or the power corresponding to the preset power is calculated as the rated remaining power, and the rated remaining power is less than the initial remaining power of the capacitor group, execute step S2131: calculate the difference between the real-time remaining power and the rated remaining power through the calculation module, and before the difference reaches the minimum, control the discharge resistance module to operate to consume the power of the capacitor group.

[0071] Figure 3 This is a structural diagram of another capacitor bank discharge system in an example of the present application. An embodiment of the present application proposes that the capacitor bank discharge system also includes an IGBT module. The IGBT module switches the connection state of the circuit through an insulated gate bipolar transistor (IGBT) and is controlled by a voltage signal. A first connection circuit is formed between the capacitor bank and the discharge resistor module, and the IGBT module is arranged in the first connection circuit.

[0072] based on Figure 3 In the capacitor bank discharge system shown, the specific method of executing step S213 or implementing step S213 by executing S2131 may be:

[0073] S213-1: before the difference in power reaches a minimum, generating a first control signal;

[0074] S213-2: Sending the control signal to the IGBT module;

[0075] S213 - 3 : The IGBT module responds to the first control signal to connect the first connection line between the discharge resistor module and the capacitor group, and the discharge resistor module obtains the output power of the capacitor group through the first connection line when in operation.

[0076] If the rated remaining power is zero and the initial remaining power is J, then the difference power is J; in one example, the calculation module determines that the rated remaining power is zero and the initial remaining power is J, and starts to send the first control signal to control the operation of the discharge resistor module. The first control signal and the second control signal are both electrical signals. The IGBT module responds to the first control signal and connects the first connection line between the discharge resistor module and the capacitor group. The discharge resistor detects that the first connection line is connected and obtains power from the capacitor group through the first connection line to operate the discharge resistor. The above process sets the IGBT module, sends an electrical signal to the IGBT module, controls the connection direction of the IGBT module, and thus controls the connection and disconnection of the first connection line. Based on the objective law that the connection of the first connection line provides the discharge resistor with electrical energy to support the discharge operation, the purpose of controlling the operation or stopping of the discharge resistor module is achieved simply and quickly.

[0077] An embodiment of the present application proposes that during the execution of S2131, the voltage feedback module still periodically collects the real-time voltage of the capacitor group, the calculation module calculates the real-time remaining power of the capacitor group based on the real-time voltage, and adjusts the process of generating the control signal based on the real-time remaining power.

[0078] If it is detected during the execution of S2131 that the difference in power reaches the minimum value, sub-steps S2132 to S2133 are executed.

[0079] S2132: Generate a second control signal, and send the second control signal to the IGBT module.

[0080] S2133: disconnecting the first connection line between the discharge resistor module and the capacitor group in response to the second control signal through the IGBT module.

[0081] The IGBT module disconnects the first connection line, and the discharge resistor module cannot obtain the electric energy to support the operation of the discharge resistor, thereby achieving the purpose of stopping the discharge resistor from working.

[0082] Continuing with the above example, when the discharge resistance module is operating the discharge resistance, the calculation module still receives the real-time voltage collected by the voltage feedback module and calculates the real-time remaining power of the capacitor group; if the real-time remaining power is JY (Y<J) after a period of time, the first control signal is still generated and sent to the IGBT module. If the real-time remaining power is zero after a period of time, the calculation module determines that the discharge resistance module has consumed power J, and sends a second control signal to control the discharge resistance module to stop operating.

[0083] If the result of executing step S211 is that when the power corresponding to the preset power is calculated as the rated remaining power, the rated remaining power is greater than the initial remaining power of the capacitor group, sub-steps S2132 to S2133 are executed.

[0084] The embodiment of the present application also proposes a method for implementing step S213. In addition to periodically detecting the real-time voltage across the capacitor group and adjusting the discharge strategy of the discharge resistor module according to the real-time voltage, for example, judging whether to control the discharge resistor module to stop running the discharge resistor according to the real-time voltage, the running time of the discharge resistor module can also be calculated in advance to measure whether the discharge resistor module should stop running based on the time.

[0085] S213 includes sub-steps: M2131 to M2132;

[0086] M2131: Calculate, by the calculation module, the target time required for the discharge resistance module to consume the difference between the initial remaining power and the rated remaining power.

[0087] For example, assuming that the rated remaining power is zero, the initial remaining power is J, and the power consumed per unit time by the discharge resistor module is J / T, then the target time required for the discharge resistor module to operate the discharge resistor to consume the difference power J is T. A timer can be set, and the calculation module starts timing when it detects that the discharge resistor module starts to operate, or the calculation module starts timing when the first control signal is sent to the IGBT module, and when the calculation module detects that the timer time reaches T, the discharge resistor module is controlled to stop operating.

[0088] M2132: When the discharge duration does not reach the target time, control the discharge resistance module to consume the power of the capacitor group.

[0089] In order to more flexibly adjust the discharge efficiency of the capacitor group, the embodiment of the present application also proposes another method of implementing step S213, setting the discharge resistance module to include discharge resistors of various resistance values, calculating the amount of electricity that the discharge resistance control module needs to consume per unit time according to the time interval required for the intense pulsed light instrument to perform different treatment operations, and the amount of electricity remaining in the capacitor group after a pulse light output ends, and selecting a discharge resistor of corresponding resistance value according to the amount of electricity that the discharge resistance control module needs to consume per unit time to meet the discharge requirements in different treatment scenarios; the time interval refers to the interval between two pulse light outputs.

[0090] The discharge resistance module is provided with a resistance switch; the resistance switch includes a relay or a contactor.

[0091] The discharge resistor module is provided with discharge resistors of different resistance values, and the resistor switcher switches the connection paths of different discharge resistors in response to the electrical signal.

[0092] S213 includes sub-steps M213-1 to M213-5;

[0093] M213-1: Get the time interval between the current time and the time when the next operation is executed.

[0094] The calculation module may firstly obtain the time for executing the next operation after the pulse light output program is executed for the current time; the time for executing the next operation may be input by the user after the user completes the current operation.

[0095] Alternatively, a data set may be established to store the corresponding relationship between treatment items and time intervals. The calculation module queries the data set to directly obtain the time interval between two adjacent pulse light outputs.

[0096] M213-2: Calculate the unit power required to consume the difference between the real-time remaining power and the rated remaining power within the time interval; the unit power refers to the power consumed by the resistor running per unit time.

[0097] M213-3: searching for the target resistance corresponding to the unit power through the calculation module, generating a third control signal according to the unit power, and sending the third control signal to the discharge resistance module.

[0098] M213-4: Responding to the third control signal through the discharge resistance module to trigger the resistance switch to switch to the target resistance;

[0099] M213-5: Before the difference power value reaches the minimum, the discharge resistance module operates the target resistance to consume the power of the capacitor group.

[0100] The discharge resistor module can not only respond to the instructions issued by the calculation module in the manner proposed in the above example and switch the discharge resistors with different resistance values ​​to meet different discharge requirements, but also switch the discharge resistors with different resistance values ​​according to the user's instructions. In the event of special circumstances, the discharge of the capacitor bank can be completed according to the user's instructions to prevent more serious situations from occurring.

[0101] The discharge resistance module is provided with a resistance switch and a resistance switch button; before the difference electric quantity has not reached the minimum, the discharge resistance module is controlled to operate to consume the electric quantity of the capacitor group, including:

[0102] The discharge resistance module detects a trigger signal of the resistance switching button, and switches the relay to the target resistance corresponding to the unit power in response to the trigger signal;

[0103] Before the difference in power reaches a minimum, the discharge resistance module is controlled to operate the target resistance to consume power of the capacitor group.

[0104] Figure 4 is a schematic diagram of the structure of a capacitor bank discharge system in another example of the present application, such as Figure 4 As shown, a third connection line is set between the calculation module and the discharge resistance module, and the discharge resistance module is provided with a resistance switching button. The calculation module sends a third control signal to the discharge resistance module, and the discharge resistance module relay responds to the third control signal and connects the target discharge resistance and the capacitor group by switching the connection path. Alternatively, the discharge resistance module relay responds to the trigger signal of the resistance switching button to switch the connection path.

[0105] Figure 5 is a structural diagram of another capacitor bank discharge system in an example of the present application, such as Figure 5 As shown, the capacitor bank discharge system further includes an isolation module, which is arranged in the second connection line between the voltage feedback module and the calculation module; the isolation module can be a linear optocoupler.

[0106] The voltage feedback module collects the real-time voltage of the capacitor group. The real-time voltage is a high-voltage signal. The voltage feedback module divides the high voltage and converts it into a low-voltage signal for feedback, and then sends the low-voltage signal to the calculation module. In order to prevent the high-voltage signal from being transmitted to the calculation module through the second connection line during the process of the voltage feedback module sending the low-voltage signal through the second connection line, causing damage such as breakdown, the second connection line is provided with an isolation module. The isolation module blocks the high-voltage electrical signal of the voltage feedback module during the process of the voltage feedback module outputting the real-time voltage to the calculation module.

[0107] The embodiment of the present application further provides a capacitor bank discharge system, the capacitor bank discharge system comprising a calculation module, a voltage feedback module and a discharge resistance module, wherein;

[0108] The calculation module is used to obtain parameter information of the next operation input by the user after the current pulse light output program is completed; the parameter information includes a signal to stop the pulse light source discharge or a preset power corresponding to the next execution of the pulse light output program;

[0109] The calculation module is also used to determine the rated remaining power required by the capacitor bank for performing the next operation according to the parameter information;

[0110] The voltage feedback module is used to monitor the real-time voltage of the capacitor group during the discharge process of the capacitor group;

[0111] The calculation module is further used to calculate the real-time remaining power corresponding to the real-time voltage, calculate the difference between the real-time remaining power and the rated remaining power, and control the discharge resistance module to consume the power of the capacitor group before the difference reaches the minimum;

[0112] The discharge resistance module is used to consume the electricity of the capacitor group in response to the instruction of the calculation module.

[0113] The capacitor bank discharge system further includes an IGBT module and an isolation module; the discharge resistor module and the capacitor bank are connected via the IGBT module; and the isolation module is arranged in a connection line between the voltage feedback module and the calculation module.
