Furthermore, the MCU unit adopts a singlechip as a processing chip. Without loss of generality, the utility model discloses a processing chip of ESP32 singlechip as the MCU unit.
Further, as shown in fig. 4, the electrical stimulation circuit specifically includes a voltage conversion circuit, a switch control circuit, a transformer circuit, a current regulation and filtering circuit, and an output electrode; the voltage conversion circuit is connected with a power circuit of the nursing terminal, amplifies the voltage of the power circuit and provides the amplified voltage to a primary coil of the transformer circuit; the transformer circuit is connected to the MCU unit and acquires a control signal to control the on-off of the electrical stimulation output of the electrical stimulation circuit; the transformer circuit amplifies the input voltage and outputs the amplified voltage to the current regulation and filtering circuit; the current adjusting and filtering circuit adjusts the output current to a human body safe current value and outputs the output current to the output electrode; the output electrode is contacted with the human body to perform electric stimulation alarm reminding.
Specifically, the operation principle of the electrical stimulation circuit is as follows: when a help seeking event push sent by a server through a wireless communication technology is received, the MCU outputs a pulse waveform with a certain frequency to the switch control circuit to control the on and off of the transformer; the voltage and current output by the secondary coil of the transformer are applied to the human body through the electrodes after passing through the current adjusting and filtering circuit. After confirming the receipt of the help message, the circuit will stop the electrical stimulation if a designated key is pressed.
The electrical stimulation circuit may be set to output electrical stimulation at a fixed frequency, or may output pulse waveforms of different frequencies depending on the duration. To realize this change, it is only necessary to set a program to make the MCU output different pulse waveforms according to the change of time, as shown in fig. 5, the waveform (i) is a pulse waveform output at a certain frequency, and the waveform (ii) changes the output pulse frequency. The two waveforms have stronger stimulation than the first one. Therefore, only under the condition of changing the pulse frequency, the time-division setting can be carried out, such as the output at the frequency of 0.5Hz in the former 20s, the output at the frequency of 1Hz in the 20-60 s, and the output at the frequency of 2Hz in the 60s or more.
As shown in fig. 6, which is a schematic diagram of an example of an electrical stimulation circuit of a nursing terminal, an ESP32 single-chip microcomputer or other chips with similar functions may be used as an MCU of the nursing terminal; the communication with the server can be realized by a wireless communication unit (if any) integrated in the singlechip, and a wireless communication unit can also be added outside the singlechip; the positioning chip in the circuit is realized by a Bluetooth circuit integrated in an ESP32 singlechip, and the positioning chip can be added outside the singlechip to realize the same effect. The system can be powered by a lithium battery or other batteries, the voltage required by other circuits such as a singlechip and the like is generated by a Low Dropout Regulator (LDO), the TLV70233 of TI company is adopted here, and other similar chips can be adopted to realize the same function. The voltage required by the primary coil of the transformer before conversion is generated by a Boost chopper circuit (Boost Converter, Boost for short), where AP3015 is selected, and other similar chips may also be used. The BOOST default state can be set to be working, and can also be controlled through a General-purpose input/output (GPIO) port of a single chip microcomputer, and the output voltage can be changed by adjusting R1 and R2, and the calculation formula is V _ I = FB (1 + R1/R2). Two triodes Q1 and Q2 are adopted to form a two-stage switch control circuit, and the two-stage switch control circuit has the function of driving amplification. When the pulse wave level output by the GPIO port of the singlechip is low, Q1 is cut off, Q2 is conducted, and the voltage output by the BOOST is output to a current adjusting and filtering circuit at the rear end through a transformer; when the pulse wave output by the GPIO port of the singlechip is high, Q1 is switched on, Q2 is switched off, the primary coil of the transformer has no voltage change, and the secondary coil does not generate output voltage. The transformer adopts ATB3225, and other transformers with similar functions can be selected. Assuming a transformer primary to secondary winding ratio of 1: X, the voltage V _ O = X × V _ I generated across the transformer. The value of X should be greater than 1 to achieve the boosting effect. D2 prevents the transformer primary winding from breaking down transistor Q2, and since the winding is an inductive device, the transformer current will flow through R8 and D2 when transistor Q2 is turned off. R9 is an adjustable resistor that can be used to adjust the magnitude of the output current. When the pulse wave frequencies output by the GPIO are different, different stimulation effects can be generated. When the keys S1 and S2 are pressed, the level recognized by the GPIO port of the singlechip is low, and the rest are high, so that the level is used as the basis for judging whether the keys are pressed or not.
Besides the alarm function, the nursing terminal has the function of electric physiotherapy. When in use, the electric stimulation output position of the nursing terminal can be aligned to human body acupuncture points, such as Hegu acupuncture point, Laogong acupuncture point and the like. Meanwhile, the MCU is set to have a proper frequency to output pulse waveforms so as to drive the transformer to output proper voltage and current to acupuncture points of a human body, thereby realizing the function of the electric physiotherapy. The frequency of the pulse waveform can be predefined, and the pulse waveform is called through a related key on the terminal equipment when in use; the pulse frequency can be set to be adjustable based on the original frequency according to different senses of each person, such as slightly increasing the pulse frequency or slightly decreasing the pulse frequency to enhance the universality. In addition, because the current adjusting and filtering circuit is reserved at the front end of the electrode, the resistance value of the potentiometer can be properly adjusted according to the self requirement during use so as to change the output current and better realize the effect of the electric physiotherapy.
Furthermore, the wireless communication technology of the present invention, including but not limited to wifi, 5G, bluetooth, etc., is within the protection range; the positioning chip adopts a GPS positioning chip or a Beidou satellite positioning chip or a Bluetooth Beacon or other existing feasible positioning chips or circuits.
