The positioning module can select a common GPS positioning chip or a Beidou satellite positioning chip or other commercially mature positioning chips, the crystal oscillator module adopts a commercially mature crystal oscillator, and the audio module adopts a commercially mature buzzer, a loudspeaker or a music player.
Furthermore, the MCU module adopts a singlechip as a processing chip. Without loss of generality, the invention adopts an ESP32 singlechip as a processing chip of the MCU module.
Further, as shown in fig. 4, the electrical stimulation module specifically includes a voltage conversion module, a switch control module, a transformer module, a current adjustment and filtering module, and an output electrode; the voltage conversion module is connected with a power supply module of the nursing terminal, amplifies the voltage of the power supply module and provides the amplified voltage to a primary coil of the transformer module; the transformer module is connected with the MCU module and acquires a control signal to control the on-off of the electrical stimulation output of the electrical stimulation module; the transformer module amplifies the input voltage and outputs the amplified input voltage to the current adjusting and filtering module; the current adjusting and filtering module 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 working principle of the electrical stimulation module 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 module to control the on and off of the transformer; the voltage and current output by the secondary coil of the transformer are applied to a human body through the electrodes after passing through the current adjusting and filtering module. After confirming the receipt of the help message, the circuit will stop the electrical stimulation if a designated key is pressed.
To achieve this, it is only necessary to set a program to cause the MCU module to output different pulse waveforms according to the change in time, as shown in fig. 5, waveform ① is a pulse waveform output at a certain frequency, and waveform ② changes the pulse frequency of the output, both of which result in a stronger stimulation of waveform ② than ①.
As shown in fig. 6, which is a schematic diagram of an example of an electrical stimulation module 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 through a wireless communication module (if any) integrated in the singlechip, and a wireless communication module can also be added outside the singlechip; the positioning module in the circuit is realized by a Bluetooth module integrated in an ESP32 singlechip, and the positioning module 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 modules such as a single chip microcomputer 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 the current adjusting and filtering module 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 module 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.
Further, as shown in fig. 3, the invention also discloses an electrical stimulation comprehensive alarm method based on the wireless communication technology, which comprises the following steps:
step 1, a user sends help seeking information through a terminal to be watched;
step 3, the server pushes the help seeking information and the positioning information to the nursing terminal together;
further, in step 3, the server acquires the current user basic information and the current on-duty nursing terminal based on the watched terminal corresponding to the help seeking information, and then pushes the help seeking information, the user basic information and the positioning information to be sent to the nursing terminal.
Step 4, the nursing terminal receives and displays the information sent by the server, inquires the current alarm reminding mode of the nursing terminal and alarms according to the alarm reminding mode;
specifically, the nursing terminal provides the setting function of the day time period and the night time period, for example, as a possible implementation, the nursing terminal adopts vibration and audio alarm in the day time period from 8 to 18 o 'clock, and adopts electrical stimulation alarm in the night time period from 18 to 8 o' clock of the next day.
And 4, the watching and protecting terminal acquires the system time of the current equipment, and then alarms according to the preset alarm reminding mode of the current time period. Or the nursing terminal acquires the site scene set by the current equipment and then gives an alarm according to a preset alarm reminding mode of the current site scene; the nursing terminal is set to be electrically stimulated to alarm in the occasions with large background noise, the occasions influencing other people and the occasions easy to fatigue; otherwise, the nursing terminal in other occasions is set to alarm the mixture of audio frequency and vibration.
The nursing terminal adopts the specific steps of electrical stimulation:
step 4.1, the MCU module outputs a pulse waveform with set frequency to the switch control module to control the conduction and the disconnection of the transformer; as a preferred embodiment, the MCU module outputs pulse waveforms with different frequencies according to different durations.
Step 4.2, generating current by the electrical stimulation module and applying the current to a human body through the electrode;
and 4.3, stopping electrical stimulation by the electrical stimulation module after the caregiver confirms that the alarm information is received.
Further, in step 4.1, the MCU module outputs pulse waveforms of different frequencies according to different durations, and then the MCU module performs a progressive electrical stimulation alarm by using a progressive enhanced pulse output frequency or the MCU unit performs an electrical therapy to the human body through an electrical stimulation circuit by using a frequency satisfying the electrical therapy.
Specifically, when the electrical stimulation alarm is performed, the electrical stimulation frequency is gradually changed. The frequency of 0.5Hz is adopted for the first 20s, namely, the electric stimulation is carried out once every two seconds, the frequency of 1Hz is adopted for 20-60 s, and the frequency of 2Hz is adopted for the electric stimulation alarm for more than 60 s. Therefore, the nursing staff can be reminded in time without causing too much stimulation to the body. It should be noted that electrical stimulation should be performed while ensuring that it is not harmful to the human body.
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.
Step 5, judging whether the caretaker confirms to receive the help seeking information within the preset time; if yes, executing step 6; if not, then,
step 6, the caregiver obtains the position of the terminal to be cared and timely goes to the site to process help seeking information and confirms that the processing is finished through the nursing terminal after the completion,
step 7, the server receives the completion information of the caregiver, further requests to acquire the positioning information of the terminal to be cared and the caregiver,
step 8, the server compares whether the positioning information of the terminal to be watched is consistent with that of the watching terminal; if yes, the current help-seeking processing is completed; otherwise, step 3 is performed to ensure that the help event is truly and efficiently completed.
The working principle of the alarm method of the invention is as follows: the server sends a positioning request to the attended terminal when receiving the help seeking information sent by the attended terminal, and the server receives the positioning information, appropriately processes the positioning information and sends the positioning information to the appointed attended terminal through a wireless communication technology. The information is displayed on the nursing terminal and alarms according to a preset mode. And if the server receives the information which is sent by the nursing terminal and confirms the receiving, the alarm is stopped. The implementation mode can be that after the caregiver presses a 'confirm receive' button on the terminal device, the MCU sends a corresponding instruction to the server through the wireless communication technology after recognizing the action; the caregiver quickly determines the position of the terminal to be cared according to the position information pushed by the terminal to be cared, and timely processes the help-seeking information on site, and then the caregiver terminal sends a 'processed' instruction to the server. The realization mode can be that a 'processing completion' key on the terminal equipment is pressed, and the MCU sends a corresponding instruction to the server through the wireless communication technology after the action is identified; when the server receives the request of the nursing terminal to end the help seeking event, the server sends a positioning invitation to the nursing terminal and the help seeking event. After receiving the positioning information, comparing, and if the positions are consistent, ending the help seeking event; if the information is inconsistent with the help seeking information, the server pushes the help seeking information to the nursing terminal again.
In summary, the invention provides an electrical stimulation scheme, and a silent sensitive touch alarm can be realized in an electrical stimulation manner in meeting rooms, hospitals, nursing homes and the like, or in occasions where other people need to be muted, or occasions where audio or vibration reminding is difficult, or in occasions or time periods where caregivers are easy to fatigue, so as to effectively remind caregivers to deal with help seeking of a cared terminal. In addition, the conventional alarm system has difficulty in effectively confirming whether the caregiver has finished the help seeking event of the cared terminal on site, and thus cannot determine whether the caregiver has actually finished the help seeking of the cared terminal. The alarm system provided by the invention can compare the positions of the nursing terminal and the terminal to be nursed finally to confirm whether the nursing person has on-site operation or not and whether the help seeking event is really completed or not, which is not possessed by the traditional alarm system.
The invention provides a comprehensive alarm system scheme based on a wireless communication technology and aiming at the problem that a caregiver cannot timely notice help seeking information sent by a terminal to be cared. When the server receives the help seeking information of the terminal to be cared, the server sends a position information request to the terminal to be cared. After the relevant information is processed, the help seeking information and the position information are transmitted to the corresponding nursing terminal through the wireless communication technology, and the alarm is started. The alarm can be a mixed alarm of vibration and audio, and can also be an electric stimulation alarm. The alarm mode can be set by a caregiver, for example, in conference rooms, hospitals, nursing homes and the like or occasions which can affect other people, occasions with high background noise and difficult effective reminding in the mode of audio frequency and the like, and occasions which are easy to fatigue or time periods and the like are set as electric stimulation alarms, and the rest time periods are mixed alarms of audio frequency and vibration; the system can also be set according to the time period, such as starting vibration and audio alarm in the daytime and starting electrical stimulation alarm at night. When the server receives the 'processing completion' information transmitted by the nursing terminal, the server initiates positioning invitation to the nursing terminal and the server, and compares the positioning invitation with the positioning invitation after receiving the position information. If the position information is consistent, the event is ended, and if the position information is inconsistent, the pushing is carried out again, so that the help seeking event is really and effectively completed.
In addition, the invention provides an electric stimulation alarm mode, and the communication between the nursing terminal and the server is mainly carried out by a wireless communication module in the circuit. In particular, the stimulation intensity can be changed by changing the frequency of the output pulse waveform of a MicrocontrollerUnit (MCU) of the nursing terminal. Generally, the stimulation to the caregiver can be gradually increased by gradually increasing the output frequency of the enhanced pulses to achieve the purpose of waking up.
By adopting the technical scheme, on one hand, a caregiver can timely notice help seeking information of a terminal to be cared so as to timely process related matters. Moreover, because the alarm mode can be set, the alarm device is suitable for alarm under various occasions, such as meeting rooms, hospitals, nursing homes and the like or occasions which can affect other people, occasions which have high background noise and are difficult to effectively remind through audio and the like, and occasions or time periods which are easy to fatigue; on the other hand, the server compares the positions of the two at the last moment, so that the help seeking event can be really and effectively completed. Besides the silent sensitive touch alarm, the scheme provided by the invention has the function of electric physiotherapy, and is beneficial to relieving the pressure of a caregiver and improving the service efficiency.
