Detailed Description
The invention provides a current regulating device, a current regulating method, a current regulating system, a controller and a therapeutic apparatus, so that the current of an electrode plate reaches the target current.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic structural diagram of a current regulator according to the present invention, where the current regulator includes: the device comprises a controller 1, a control switch 2, a current control module 3, an electrode plate 4 and a current acquisition module 5;
The control switch 2 is connected with the controller 1 and is used for outputting a signal representing the current regulation quantity;
the current acquisition module 5 is connected with the controller 1 and is used for acquiring the current value of the electrode plate 4;
The controller 1 is connected with the electrode slice 4 and is used for acquiring current adjustment quantity, sending a first current output signal to the current control module 3 according to the current adjustment quantity, acquiring a current value of the electrode slice 4 acquired by the current acquisition module 5, and outputting a second current output signal to the current control module 3 according to the current represented by the first current output signal and the current value of the electrode slice 4;

When the multi-channel electrode is applied to a human body, the multi-channel output current is different due to different surface impedance of the human body, so that a user generates uncomfortable feeling, and the current balance of the multi-channel output electrode is needed. Specifically, the current output to the electrode plate 4 is the same, and the current of the electrode plate 4 is different due to the different impedances, so it is necessary to collect the current of the electrode plate 4 and adjust the current output to the electrode plate 4 so that the current values of the electrode plates 4 are equal.
The control switch 2 can adjust the current adjustment amount output to the controller 1 according to the control of a user, and the controller 1 controls the current control module 3 after determining the current adjustment amount, and sends a first current output signal according to the current adjustment amount, wherein the voltage value represented by the first current output signal is the voltage value to be achieved by the electrode slice 4. When the current control module 3 outputs a current value to the electrode pad 4 according to the first current output signal, the current reflected to the electrode pad 4 exhibits a different current value due to a difference in human body impedance even though the same current is output. Therefore, the current of the electrode plate 4 is acquired through the current acquisition module 5, the acquired current is compared with the current value corresponding to the first current output signal, and if a difference exists, the output current value needs to be readjusted until the difference approaches zero. The current corresponding to the second current output signal is output to the electrode plates 4, so that the current value of the electrode plates 4 is equal to the current corresponding to the first current output signal, and the current equality between the electrode plates 4 is realized.
Specifically, the current control module 3 is an FPGA (Field-Programmable gate array).
The invention discloses a current regulating device, which relates to the field of current control and comprises a controller 1, a control switch 2, a current control module 3, an electrode plate 4 and a current acquisition module 5; the controller 1 sends a first current output signal to the current control module 3 according to the current adjustment quantity, and outputs a second current output signal to the current control module 3 according to the current represented by the first current output signal and the current value of the electrode plate 4; the current control module 3 outputs a current corresponding to the first current output signal or the second current output signal to the electrode pad 4. The current adjustment quantity is determined by controlling the switch 2, the current value of the electrode plate 4 is determined by the current acquisition module 5, the controller 1 controls the current output module to output corresponding current to the electrode plate 4 according to the current adjustment quantity, the current of the electrode plate 4 is different due to different impedance, and then the current of the electrode plate 4 is adjusted by generating a second current output signal according to the current of the electrode plate 4 and the target current, so that the current of the electrode plate 4 reaches the target current.
Based on the above embodiments:
In some embodiments, a digital-to-analog converter and an operational amplifier are also included;
the input end of the digital-to-analog converter is connected with the output end of the current conversion module and is used for converting the digital signal output by the current conversion module into an analog signal;
the input end of the operational amplifier is connected with the output end of the digital-to-analog converter, and the output end of the operational amplifier is connected with the electrode plate 4 and is used for amplifying the voltage corresponding to the analog signal and then outputting the amplified voltage to the electrode plate 4.
Considering that the current conversion module is an FPGA, the signals output by the FPGA are digital signals, so a digital-to-analog converter needs to be set to convert the digital signals output by the FPGA into analog signals and then supply power to the electrode plate 4. Considering that the voltage output by the FPGA is generally small, an operational amplifier needs to be set to amplify the voltage so as to meet the power supply requirement of the electrode slice 4.
In some embodiments, the control switch 2 is a rotary encoder;
the controller 1 is further used for dividing the range of the output current into preset gears and determining the corresponding relation between the rotation direction of the rotary encoder and the increase and decrease of the gears;
obtaining a current adjustment amount, comprising: the rotational direction of the rotary encoder is determined and the current is increased or decreased depending on the rotational direction.
Since the control switch 2 is a rotary encoder, it is possible to characterize the control of the current that the user wants during the rotation of the rotary encoder. The range of the output current is divided into preset gears in advance, the gears are adjusted once every time the rotary encoder rotates, and the preset corresponding relation between the rotation direction and the increase and decrease of the gears is achieved, for example, one gear is reduced by left rotation, and one gear is increased by right rotation.
Specifically, if the output current is in the range of 0-60mA, the output current is divided into 100 gears, the current of each gear is 0.6mA, if the preset mode is a left-handed reduction gear and a right-handed increase gear, the current is reduced by 0.6mA when the left-handed rotation of the rotary encoder is detected, and the current is increased by 0.6mA when the right-handed rotation of the rotary encoder is detected.
In some embodiments, outputting the second current output signal to the current control module 3 according to the current characterized by the first current output signal and the current value of the electrode pad 4 comprises:
determining a difference between the current value of the electrode pad 4 and the current characterized by the first current output signal;
if the difference is greater than 0, the current corresponding to the second current output signal is smaller than the current corresponding to the first current output signal;
If the difference is smaller than 0, the current corresponding to the second current output signal is larger than the current corresponding to the first current output signal;
If the difference is 0, the second current output signal is not output to the current control module 3.
It will be appreciated that the current corresponding to the first current output signal is the current to be achieved by the electrode pads 4, and the controller 1 controls the current output by each electrode pad 4 to be equal, but because the impedances of the respective positions are different, it is necessary to send a second output current signal to adjust the current of the electrode pad 4, and send the second current output signal so that the current of the final electrode pad 4 is equal to the current corresponding to the first current output signal.
Specifically, if the difference between the current value of the electrode slice 4 and the current represented by the first current output signal is greater than 0, it is proved that the current value of the current electrode slice 4 is greater than the expected value, and the current value needs to be adjusted to be smaller, so that the current corresponding to the second current output signal is smaller than the current corresponding to the first current output signal. On the contrary, if the difference between the current value of the electrode plate 4 and the current represented by the first current output signal is smaller than 0, it is proved that the current value of the current electrode plate 4 is smaller than the expected value, and the current value needs to be adjusted to be larger, so that the current corresponding to the second current output signal is larger than the current corresponding to the first current output signal. If the difference is zero, it is proved that the current of the present electrode pad 4 is in line with the expectations, without readjustment.

The working frequency range of the three-dimensional dynamic interference electric therapeutic instrument is 2 kHz-6 kHz, and the working frequency is non-fixed; the principle of current measurement by the current transformer is that the current is calculated by measuring the induced voltage and is irrelevant to the current of the primary end, so that the strong current is measured by the current transformer, because the voltage is far higher than the measuring range of the measuring system, the voltage can be reduced according to the proportion by the current transformer, so as to meet the requirement of the measuring system.

When the current control module 3 outputs a current value to the electrode pad 4 according to the first current output signal, the current reflected to the electrode pad 4 exhibits a different current value due to a difference in human body impedance even though the same current is output. Therefore, the current of the electrode plate 4 is acquired through the current acquisition module 5, the acquired current is compared with the current value corresponding to the first current output signal, and if a difference exists, the output current value needs to be readjusted until the difference approaches zero. The current corresponding to the second current output signal is output to the electrode plates 4, so that the current value of the electrode plates 4 is equal to the current corresponding to the first current output signal, and the current equality between the electrode plates 4 is realized.
Specifically, the current control module 3 is an FPGA (Field-Programmable gate array).
