[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0028] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Figure 1 The present invention is a flowchart of a method for protecting and controlling a high-power shortwave therapeutic apparatus according to an embodiment of the present invention.

[0030] like Figure 1 As shown, a protection control method for a high-power shortwave therapeutic device includes steps S1 to S7.

[0031] Step S1: respectively collecting a first forward voltage value and a first reverse voltage value through a redundant acquisition circuit, and obtaining a second forward voltage value and a second reverse voltage value according to a feedback signal of a solid-state power source.

[0032] The feedback signal is the output signal of the solid-state power source, so the value of the power input (including the positive power input and the negative power input) of the solid-state power source can be calculated based on the output of the solid-state power source.

[0033] In one embodiment, the output signal of the solid-state power source is filtered; the filtered output signal is rectified to obtain a DC signal; the DC signal is filtered to obtain a positive voltage signal and a negative voltage signal; the second forward voltage value is obtained based on the positive voltage signal, and the second reverse voltage value is obtained based on the negative voltage signal.

[0034] Step S2: obtaining a first power of the shortwave therapeutic apparatus according to the first forward voltage value and the first reverse voltage value, and obtaining a second power of the shortwave therapeutic apparatus according to the second forward voltage value and the second reverse voltage value.

[0035] The shortwave therapy device's historical output power and the corresponding forward and reverse voltage values ​​are obtained, and a mathematical formula is used to establish a relationship between the shortwave therapy device's output power, the forward and reverse voltage values. A power is obtained from the first forward and reverse voltage values, and this power is referred to as the first power. Similarly, a power is obtained from the second forward and reverse voltage values, and this power is referred to as the second power.

[0036] Step S3: Obtain display power through the display.

[0037] Among them, the display frequency P The value of 0 is passed through the first power P 1 and 2nd power P 2 updates and display frequency P The initial value of 0 is the power that the medical staff expects the shortwave therapy device to output. The output power of the shortwave therapy device is the output power of the solid-state power source in the shortwave therapy device.

[0038] In particular, when the actual output power of the shortwave therapy device changes slightly, the display frequency P The value of 0 changes due to the actual power. P0 can be regarded as the "display value" of the actual power. In the case that the actual output power of the shortwave therapy device changes greatly, that is, when a large difference is detected between the actual power and the displayed power at a certain moment, it is necessary to adjust the actual output power of the shortwave therapy device to match the displayed frequency. P 0 is closer, which can be regarded as the "standard value" of actual power. Based on this, the actual output power of the shortwave therapy device fluctuates within a certain range, and can be displayed by P 0 is more accurately shown on the display.

[0039] Furthermore, the actual output power of the shortwave therapy device is different from the displayed power P The greater the difference between 0, the faster the frequency of detecting the actual output power of the shortwave therapy device. P When there is a certain difference between 0 and the actual output power, increase the displayed power P 0 as the "display value" shows the accuracy of the actual output power; P 0 and the actual output power, shorten the time this situation exists, and avoid the patient from being harmed by the excessive power output of the shortwave therapy device for a long time; P When there is basically no difference between 0 and the actual output power, the frequency of collecting the actual output power is reduced, thereby reducing the burden on the controller (MCU).

[0040] Step S4: calculating a first relative value according to the first power and the display power.

[0041] Wherein, the first relative value n 1Satisfy:

[0042] ,

[0043] When the first power P 1 and display power P 0 is small, that is, the absolute value of the difference between the two is equal to the displayed power P 0 is less than or equal to 0.05, the second relative value n 2 is 1; when the first power P 1 and display power P There is a certain difference between the values ​​​​between 0 and 1, that is, the absolute value of the difference between the two is different from the displayed power. P 0 is less than or equal to 0.15 and greater than 0.05, the second relative value n The value of 2 is 2; when the first power P 1 and display power P 0, that is, the absolute value of the difference between the two is greater than the displayed power. P0 is greater than 0.15, the second relative value n The value of 2 is 3.

[0044] Step S5: Calculating a second relative value according to the second power and the display power.

[0045] Wherein, the second relative value n 2 Satisfaction:

[0046] ,

[0047] When the second power P 2 and display power P 0, the difference between the two values ​​is small, that is, the absolute value of the difference between the two is equal to the displayed power P 0 is less than or equal to 0.05, the second relative value n 2 is 1; when the second power P 2 and display power P There is a certain difference between the values ​​​​between 0 and 1, that is, the absolute value of the difference between the two is different from the displayed power. P 0 is less than or equal to 0.15 and greater than 0.05, the second relative value n The value of 2 is 2; when the second power P 2 and display power P 0, that is, the absolute value of the difference between the two is greater than the displayed power. P 0 is greater than 0.15, the second relative value n The value of 2 is 3.

[0048] Step S6: controlling the output power of the solid-state power source according to the first relative value and the second relative value.

[0049] Among them, the first relative value n 1 represents the first power P 1 and display power P The difference between 0 and the second relative value n 2 represents the second power P 2 and display power P 0, and display the frequency P The initial value of 0 is the power that the medical staff expects the shortwave therapy device to output, so the power is displayed P 0 cannot fluctuate too much. n 1 or the second relative value n 2 is 3, and the first relative value n 1 and the second relative value n When 2 is not 1, it means that the output power of the shortwave therapy device is too large or too small. P 1 and display powerP 0 and the second power P 2 and display power P 0, you can judge whether you need to increase or decrease the output power of the shortwave therapy device.

[0050] In one embodiment, a protection and control method for a high-power shortwave therapeutic device further includes: obtaining the temperature of a patient's treated area using an infrared temperature sensor, and determining the magnitude of the temperature change within a predetermined time period. The infrared temperature sensor obtains the temperature of the patient's treated area at a 1 second interval, and calculates in real time the absolute value of the difference between two sets of temperature values ​​separated by one period, where the absolute value represents the magnitude of the temperature change. When the magnitude of the temperature change exceeds a threshold, output of the solid-state power source is stopped.

[0051] Among them, when the patient is being treated by the shortwave therapy device, the temperature of the treatment area will usually rise slowly. The temperature detected by the infrared temperature sensor when the patient leaves the shortwave therapy device will be different from the temperature detected by the infrared temperature sensor during normal treatment. Therefore, the temperature change within a certain period of time can be used to determine whether the patient has left. When the temperature change within a certain period of time is greater than the threshold, it is considered that the patient has left the shortwave therapy device. At this time, in order to protect the solid-state power source in the shortwave therapy device, the output power of the solid-state power source needs to be changed. When the first relative value n When 1 is 1 or 2, the output power of the solid-state power source is not changed; when the first relative value n 1 is 3, and the first power P 1 is less than the displayed power P 0, increase the output power of the solid-state power source by a predetermined power amplitude; when the first relative value n 1 is 3, and the first power P 1 is less than the displayed power P When the power level is 0, the output power of the solid-state power source is reduced by a predetermined power amplitude, which is 10 watts.

[0052] Figure 2 is a flowchart of step S2 according to an embodiment of the present invention.

[0053] like Figure 2 As shown, step S2 includes steps S201 to S204.

[0054] Step S201: Obtain historical data, where the historical data includes historical forward voltage values, historical reverse voltage values, and historical power.

[0055] In one embodiment, the shortwave therapy device is obtained during past use. piThe positive and negative voltage values ​​output by the power supply under output power. pi = i × 5 watts, and i is a positive integer greater than 0 and less than 15. The shortwave therapeutic apparatus has multiple sets of corresponding positive voltage values ​​and negative voltage values ​​at any output power.

[0056] Step S202: obtaining a mapping function between historical voltage values ​​including historical forward voltage values ​​and historical reverse voltage values ​​and power.

[0057] In one embodiment, an initial mapping function is first constructed, where the power p satisfy: p = α 0 u 1+ β 0 |u 2|. Among them α 0 is the initial positive voltage parameter, β 0 is the initial negative voltage parameter, u 1 is the forward voltage value, u 2 Reverse voltage value. Update the positive voltage parameter and negative voltage parameter in the mapping function through historical data to obtain the updated mapping function: p = αu 1+ β|u 2|, where α is the updated positive voltage parameter, β is the updated negative voltage parameter.

[0058] Step S203: Obtaining a first power of the shortwave therapy device according to the mapping function, the first forward voltage value, and the first reverse voltage value. P 1.

[0059] The first forward voltage value is used as the forward voltage value u 1 is input to the mapping function, and the first reverse voltage value is used as the reverse voltage value u 1 is input to the mapping function and the power is calculated p The first power P 1.

[0060] Step S204: Obtain the second power of the shortwave therapy device according to the mapping function, the second forward voltage value and the second reverse voltage value. P 2.

[0061] The second forward voltage value is used as the forward voltage value u 1 is input to the mapping function, and the second reverse voltage value is used as the reverse voltage value u 1 is input to the mapping function and the power is calculated pThe second power P 2.

[0062] Figure 3 is a flowchart of step S6 according to an embodiment of the present invention.

[0063] like Figure 3 As shown, step S6 includes steps S601 to S603.

[0064] Step S601: In response to the first relative value n 1 is 1, and the second relative value n 2 is 1, and the voltage data acquisition frequency is adjusted to f 1.

[0065] The voltage data includes: the first forward voltage value, the first reverse voltage value, the second forward voltage value, and the second reverse voltage value. f The value of 1 is a preset value. In one embodiment, f The value of 1 is one-third of Hertz, which means that voltage data is collected every 3 seconds.

[0066] Furthermore, when the first relative value n 1 is 1, and the second relative value n When 2 is 1, it means that the power obtained through the redundant acquisition circuit and the feedback signal of the solid-state power source is basically consistent with the power displayed on the display. At this time, it is determined that the power displayed on the display is consistent with the actual output power of the solid-state power source, and there is no need to adjust the displayed power or the output power of the solid-state power source.

[0067] Step S602: In response to the first relative value n 1 is 2, or the second relative value n 2 is 2, and the acquisition frequency of the voltage data is adjusted to f 2.

[0068] Among them, when the first relative value n 1 is 2, and the second relative value n When 2 is 2, it means that there is a certain difference between the power obtained through the redundant acquisition circuit and the feedback signal of the solid-state power source and the power displayed on the monitor. At this time, it is suspected that the power displayed on the monitor is different from the output power of the solid-state power source. However, the output power of the solid-state power source is not changed. Only the acquisition frequency of the voltage data is increased to speed up the update of the power displayed on the monitor.

[0069] Step S603: In response to the first relative value n 1 is 3, and the second relative value n 2 is 3, and the acquisition frequency of the voltage data is adjusted to f 3, and according to the first powerP 1. The second power P 2 and the display power P 0 controls the output power of the solid-state power source, wherein, f 1< f 2< f 3.

[0070] Among them, when the first relative value n 1 is 3, and the second relative value n When 2 is 3, it means that the power obtained through the redundant acquisition circuit and the feedback signal of the solid-state power source is significantly different from the power displayed on the display. At this time, it is determined that the power displayed on the display is different from the output power of the solid-state power source. While increasing the acquisition frequency of the voltage data and speeding up the update speed of the power displayed on the display, the actual output power of the solid-state power source is also controlled.

[0071] Furthermore, when the first power P 1 is less than the displayed power P 0 and the second power P 2 is less than the displayed power P 0, the output power of the solid-state power source is reduced by a predetermined power amplitude. P 1 is less than the displayed power P 0 and the second power P 2 is less than the displayed power P 0, the output power of the solid-state power source is increased by a predetermined power amplitude.

[0072] It should be noted that if the first relative value n 1 is 3 and the second relative value n 2 is 1, indicating the first power P 1. The second power P 2. If the difference between the values ​​is large, it is possible that the redundant acquisition circuit for detecting the positive and negative voltage input voltages has failed, or it may be that the solid-state power source itself has failed, causing its feedback signal to be affected. In this case, it is necessary to perform fault detection on the solid-state power source and the redundant acquisition circuit. Similarly, the first power will not appear under normal circumstances. P 1 is greater than the displayed power P 0 and the second power P 2 is less than the displayed power P 0, or when the first power P 1 is less than the displayed power P 0 and the second power P 2 is greater than the displayed power P0. When the above two situations occur, it is considered that the redundant acquisition circuit fails or the solid-state power source itself fails, and both are tested.

[0074] like Figure 4 As shown, a high-power shortwave therapeutic device protection control device includes: a redundant acquisition circuit, which is used to receive a first radio frequency signal to detect the positive voltage value of the input shortwave therapeutic device, and is also used to receive a second radio frequency signal to detect the reverse voltage value of the input shortwave therapeutic device; an infrared temperature sensor, which is used to detect the temperature of the patient's treatment area and transmit the temperature data to the MCU; a shortwave therapeutic device, which receives the control signal of the MCU and outputs high-frequency shortwave, thereby treating the area of ​​the patient that needs treatment, the shortwave therapeutic device includes a solid-state power source, and the solid-state power source is used to output high-frequency shortwave; a display, which is connected to the MCU, and is used to receive and display the real-time output power of the shortwave therapeutic device. P 0; MCU, which is used to implement a high-power short-wave therapeutic device protection control method described in a specific implementation manner.

[0075] In one embodiment, the display is a capacitive touch screen, used to input treatment data and transmit it to the MCU. The treatment data includes the output power of the solid-state power source and the start time of treatment. Capacitive touch screens operate by detecting touch location using the effect of the human body or other charged objects on the electric field. When a finger touches the screen, the electric field on the screen changes, and sensors detect this change and determine the touch location. Capacitive touch screens typically consist of a layer of conductive glass or film coated with a highly conductive material, such as indium tin oxide (ITO), to form a capacitive sensing area. When a finger touches the screen, the charge on the screen changes, enabling touch detection and location.
