Description

Household ward unit management system

Technical Field

The present disclosure relates to a home ward unit management system, and more particularly, to a home ward unit management system capable of simultaneously monitoring a plurality of physiological parameters.

Background

Along with the increasingly rapid rhythmization of social life, health problems of people are increasingly prominent, chronic diseases such as cardiovascular and cerebrovascular diseases, hypertension and the like become human health killers, and even diseases caused by abnormal blood pressure are increasingly plagued young people. Therefore, convenient and easy-to-use health monitoring devices are becoming an urgent need for society. Especially, under the condition that medical resources are increasingly tense, the bed of the hospital is also tense, if a simple ward can be built at home, a plurality of preoperative or postoperative patients can be enabled to realize preoperative monitoring or postoperative rehabilitation and monitoring processes at home, and the pressure of the medical resources and the postoperative care cost of the patients can be reduced. However, when the patient is at home, the patient lacks supervision of nurses, and the patient is more free, so that the patient can obtain the same monitoring effect as a hospital ward by providing remote monitoring for the postoperative or users needing long-time monitoring, which is an urgent need.

Currently, most of the devices for physical examination in the market are single-function devices, such as mercury or electronic thermometer for measuring body temperature, stethoscope for measuring heart beat, upper arm or wrist type blood pressure meter for measuring blood pressure, finger oximeter for measuring blood oxygen, electrocardiograph for measuring ECG, HOLTER 24-hour dynamic electrocardiograph or 24-hour dynamic blood pressure meter. These single physiological parameter detection processes are complex and very time and effort consuming for the user. For various parameter results, the user is very inconvenient to understand and read, and no expert knowledge is needed to relate various parameters. And the single function device can not provide abundant information for remote monitoring, which is far from the ward monitoring effect of the actual hospital.

Therefore, in conventional physiological parameter detection, there is a need for a detection result that can acquire various physiological parameters of a human body at the same time and can integrate various parameters so as to realize monitoring of a patient or a ward of a user before or after an operation, so as to provide monitoring assistance and advice or warning to the user in time.

Fig. 3 is a schematic view showing a state of the blood oxygen monitor managed by the home ward unit management system according to the present disclosure. As shown in fig. 3, the blood oxygen monitor 150 includes: blood oxygen collection control (WPO) 152 and finger clip type blood oxygen probe 151, blood oxygen detector 150 and blood oxygen probe 120 are connected to each other by communication wire 155. The blood oxygen monitor 150 is formed in an arc shape matching the wrist at a lower portion thereof in contact with the wrist, and is mounted with a display screen 153 at an upper portion thereof for presenting the detection result to the user. Wrist straps 157 are mounted on both sides of the oximeter 150 so as to be wearable and fastened to the wrist of the user. The blood oxygen monitor 150 is provided with a fixing device 180 at a portion between the upper edge of the side where the wrist strap is attached and the display screen 157, and the blood oxygen probe 120 is provided with a fixing device 154 at a side surface thereof. The fixing device 154 and the fixing device 156 are detachably assembled with each other so that the blood oxygen collection control 151 and the blood oxygen probe 151 are fixed to each other.

As shown in fig. 3, the fixing device 154 of the blood oxygen monitor 150 is a sliding groove structure, and the fixing device 156 on the side of the blood oxygen probe 151 is a corresponding sliding rail structure matched with the sliding groove. The blood oxygen detector 152 and the blood oxygen probe 151 are fixed to each other in a state of not being used by the slide rail structure fixing device 156 being slid fitted into the slide rail structure fixing device 154. Alternatively, the securing means 154 and the securing means 156 may be a pair of snap structures.

Alternatively, the fixture 154 and the fixture 156 may be magnets that are coupled to each other. For example, the oximeter fixture is an N-type magnet and the fixture on the side of the oximeter probe is an S-type magnet. Through this flexible fixation, the blood oxygen detector 150 can ensure that the blood oxygen probe 151 is in a safe fixed state when not in use, so that the blood oxygen probe 151 is not damaged or the activity of the user is not affected.

Although the blood oxygen detector 150 is described herein as being split into two components, in practice the blood oxygen collection control 152 may also be integrated into the finger-clip-on blood oxygen probe 151. The blood oxygen detector 150 may be, for example, a blood oxygen collection control ring or a blood oxygen collection Wristwatch (WPO). The blood oxygen detector 150 may be connected to one of the interfaces of the signal collection assembly 110 via a signal line or may communicate with the signal collection assembly 110 via a communication means such as 2.4GHz bluetooth. When wearing the blood oxygen detector 150 on the hand (arm, wrist, etc.) of a user wearing an electrocardiograph garment or lying on a mattress, fingers extend into the finger-clip type blood oxygen probe 151, then the user controls a light emitting tube and a photoelectric receiving tube of the blood oxygen probe in the finger-clip type blood oxygen probe 151 through a blood oxygen acquisition control 152, blood oxygen signals of the user are detected, information such as blood oxygen values, pulse waves, pulse rates and the like of the user are obtained after calculation, and the information is sent to the signal collecting assembly 110 through a wired mode, 2.4GHz Bluetooth or a wireless signal, and then the information is sent to the control assembly 120 from the signal collecting assembly 110 for data processing, display and storage.

Fig. 4 is a schematic diagram of an electrocardiographic garment 140 of a home ward unit managed by the home ward unit management system according to the present disclosure. As shown in fig. 4, the electrocardiograph garment 140 includes an electrocardiograph collection box which is fastened to the electrocardiograph collection seat 147 by being arranged thereon and connected to the signal collection assembly in a wireless manner, a pair of differential signal electrodes arranged above and below the heart position of the human body inside the electrocardiograph garment, and a reference electrode arranged below the differential signal electrodes inside the electrocardiograph garment, and the electrocardiograph collection box is connected to the differential signal electrodes and the reference electrode by signal wires embedded in the electrocardiograph garment so as to acquire the user electrocardiograph signals obtained by the first, second and third electrocardiograph acquisition electrodes and is not wirelessly transferred to the signal collection assembly. Specifically, the electrocardiograph garment 140 is a thin garment made of a main body material that is non-conductive. The electrocardiograph garment includes a first electrocardiograph acquisition electrode (on the back shoulder), a second electrocardiograph acquisition electrode 148, and a third electrocardiograph acquisition electrode 149. The first, second and third electrocardiograph collecting electrodes 148 and 149 are first, second and third electrocardiograph collecting electrode strips, respectively, that is, the electrocardiograph collecting electrodes are strip-shaped electrodes. The first and second electrocardiograph collecting electrodes 148 are arranged as a pair of differential signal electrodes at the upper and lower ends of the inside of the electrocardiograph garment corresponding to the heart position of the human body, respectively, so that differential electrocardiograph signals at the upper and lower ends of the heart position of the human body can be obtained. Specifically, the first electrocardiograph acquisition electrode is arranged as one differential signal electrode above the position corresponding to the heart of the human body inside the electrocardiograph garment 140. The second electrocardiograph acquisition electrode 148 is arranged as another differential signal electrode below the position corresponding to the heart of the human body inside the electrocardiograph garment. The third electrocardiographic acquisition electrode 149 is arranged as a reference electrode at a position below the second electrocardiographic acquisition electrode 148 inside the electrocardiograph garment. An electrocardiograph signal collecting seat 147 is also arranged on the electrocardiograph garment 140 and is positioned at a position outside the electrocardiograph garment, which is different from the first, second and third electrocardiograph collecting electrodes. The electrocardiograph signal collection seat 147 includes three electrode buttons, such as a first electrode button 141, a second electrode button 142, and a third electrode button 143 shown in fig. 4. One side of the first electrode buckle 141 facing the inner side of the electrocardiograph garment is embedded with the first electrocardiograph acquisition electrode through insulation, one side of the second electrode buckle 142 facing the inner side of the electrocardiograph garment is embedded with the second electrocardiograph acquisition electrode 148 through insulation, and one side of the third electrode buckle 143 facing the inner side of the electrocardiograph garment is embedded with the third conductive wire 146 and the third electrocardiograph acquisition electrode 149 through insulation. Thus, the first, second and third electrocardiograph collecting electrodes 148, 149 respectively transmit electrocardiograph signals collected from the body surface of the human body to the corresponding first, second and third electrode buttons 141, 142, 143 fastened on the electrocardiograph signal collecting seat through the respective connected wires. Corresponding electrocardiograph signal collection boxes (not shown) are buckled on the electrocardiograph signal collection seat 147, and electrode buckles corresponding to the first electrode buckle 141, the second electrode buckle 142 and the third electrode buckle 143 are arranged in the first electrocardiograph signal collection box. When the first electrode buckle 141, the second electrode buckle 142 and the third electrode buckle 143 are male buckles, the electrode buckle in the electrocardiograph signal collection box is female buckles, whereas when the first electrode buckle 141, the second electrode buckle 142 and the third electrode buckle 143 are female buckles, the electrode buckle in the first electrocardiograph signal collection box is male buckles. Although the electrocardiograph signal collection seat 147 is shown here as comprising three electrode buttons, it is also possible to use three electrical contacts, and thus, three point contacts are also used in the corresponding electrocardiograph signal collection box. The electrocardiosignal acquisition box acquires signals after receiving electrocardiosignals transmitted by the three electrocardiosignal acquisition electrodes through the electrocardiosignal collection seat, and the signals are transmitted to a back-end platform (mobile phone APP, a matched host computer and the like) for analysis and storage in real time or in a centralized wireless way after being filtered, amplified and denoised, and can also store backup in a local memory. The back of the inner side of the electrocardiograph garment further comprises a body temperature sensing unit, the thermistor senses the surface temperature of a human body and gathers the surface temperature to the signal gathering assembly, so that the signal gathering assembly amplifies the variation of the acquired thermistor resistance through the built-in operational amplifier, and the body temperature of a user is calculated.

Returning to fig. 2. As shown in fig. 2, the home ward unit managed by the home ward unit management system may further include an electrocardiographic mattress 130 for detecting electrocardiographic signals of the user lying on the mattress, and an interface for an electrocardiographic signal detection circuit of the signal collection assembly is connected to three strip-shaped flexible electrodes for detecting electrocardiographic signals of the user. When the user is lying on the mattress 130, the electrocardiographic detection circuitry within the signal collection assembly 110 acquires electrocardiographic signals from the electrode contacts. The control component 120 forms an ECG electrocardiogram based on the electrocardiographic signals transmitted from the electrocardiographic signal detection circuitry within the signal aggregation component. If desired, the electrocardiograph signal detection circuitry may also be disposed directly within the mattress and send the acquired signals to the signal collection assembly 110. The mattress shown in fig. 2 is divided into six parts from left to right, the first part, the third part and the fifth part are made of conventional pure cotton cloth, the second part, the fourth part and the sixth part are made of silver fiber conductive cloth, conductive buttons are attached to the side edges of the silver fiber conductive cloth, the silver fiber conductive cloth is used as an electrocardio acquisition sensor, and the electrodes can be silver fiber electrodes. The second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth can be used as upper limb electrocardio electrodes, and electric signals collected from human bodies by electrode parts of the fiber conductive cloth can be transmitted to an instrument amplifier through a lead detection circuit. The width of the second part and the fourth part is 7 cm to 15 cm in order to adapt to the acquisition of the chest electrocardiosignals and the leg signals of the human body. This is because, on the one hand, the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth need to be located at both ends of the heart of the user respectively when in use, and the distance between the upper end of the heart and the shoulder is limited. Therefore, the width of the electrode is limited by this distance. On the other hand, in a certain range, the wider the width of the electrode, the larger the contact area between the electrode and the human body, the clearer the waveform, and no clutter. For example, if the width of the electrodes is less than 7 cm, the peak value collected by the mattress may be less than 1.0 volt, which can be detrimental to the effectiveness of the measurement of the electrocardiographic signal parameters. On the other hand, the wider the electrode width, the more material is required to make the electrode, which increases the manufacturing cost of the acquisition pad. The measurement result is weighed against the cost, and the widths of the second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth can be selected to be 7 cm to 15 cm. Optionally, the widths of the second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth are the same. The inventors found from practical measurements that the peak value of the signal acquired when the width of the second and fourth portions was 9 cm was about 1.7 volts after amplification, which is sufficient for the measurement of the physiological parameters of the heart. In addition, if the widths of the second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth are increased from 12 cm, the peak value is not increased significantly correspondingly. Based on this, it is preferable that the width of the electrocardiographic acquisition sensor a and the width of the electrocardiographic acquisition sensor B be 9 cm to 12 cm. Therefore, the width of the electrocardiographic acquisition sensor a and the electrocardiographic acquisition sensor B is preferably 12 cm. As shown in fig. 2, the interval between adjacent two of the second part of the silver fiber conductive cloth, the fourth part of the silver fiber conductive cloth and the sixth part of the silver fiber conductive cloth (i.e., the third part and the fifth part) is 15 cm to 20 cm, and the interval part is composed of cotton fabric. Theoretical and experimental data indicate that the distance of the separation between the second portion of silver fiber conductive cloth and the fourth portion of silver fiber conductive cloth has a significant effect on the measurement of the acquired electrocardiographic signals. The second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth for collecting electrocardiosignals are respectively positioned at the upper end and the lower end of the heart, so that the signal quality is the best. Too wide or too narrow a spacing may result in too much signal clutter or too small an amplitude. The preferable distance between the electrodes of the electrocardio-acquisition pad is 15 cm, which is relatively suitable for the heart size of most people, and the wave crest of the waveform of the acquired electrocardio-signal is obvious and the signal-to-noise ratio is large.

Further, the second portion of the silver fiber conductive cloth, the fourth portion of the silver fiber conductive cloth, and the sixth portion of the silver fiber conductive cloth have lengths of 70 cm to 100 cm, preferably 90 cm. As described above, the human body electrocardiosignal is a weak electric signal. Electrocardiographic signals are often subject to various noise disturbances, such as human motion. In this embodiment, the second portion of the silver fiber conductive cloth, the fourth portion of the silver fiber conductive cloth, and the sixth portion of the silver fiber conductive cloth are rectangular and are each integral. This allows the person to turn over on the acquisition pad while maintaining the person in contact with the second portion of the silver fiber conductive cloth and the fourth portion of the silver fiber conductive cloth over a larger area. The second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth are parallel to each other, and the second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth are parallel to the head of the mattress. This keeps the spacing between the second and fourth portions of silver fiber conductive cloth unchanged. Therefore, the collection of electrocardiosignals can not be influenced by turning over the common user when the common user sleeps on the collection pad. The accuracy of the measurement result is effectively ensured.

The sixth portion of silver fiber conductive cloth may be used as the leg driving electrode. The second part of the silver fiber conductive cloth, the fourth part of the silver fiber conductive cloth and the sixth part of the silver fiber conductive cloth which are used as the electrocardio acquisition circuit have larger areas, so that the acquired signal strength is larger and the signal is more stable.

In addition, the second part of silver fiber conductive cloth and the fourth part of silver fiber conductive cloth can comprise silver fiber conductive fabrics and copper-nickel alloy fiber conductive fabrics. The conductive fabric is a conductor and can play a role in potential difference signal measurement. The conductive fabric can be capacitively coupled to the human body, and because the conductive fabric is relatively thin and flexible, it can also physically conform well to the acquisition pad body, which can make the acquisition pad more comfortable. In order to make the user lie on the collecting pad more comfortable, the thickness of the second part of silver fiber conductive cloth, the fourth part of silver fiber conductive cloth and the sixth part of silver fiber conductive cloth is 0.5 mm to 1.2 mm, preferably 1 mm, and the conductivity of the electrode and the softness of the bed sheet can be maintained.

Alternatively, in order to enhance the detection effect of the electrocardiographic signal, the user may be required to wear the electrocardiograph garment 140 at the time of detection, the electrocardiograph garment 140 having a plurality of electrodes extending in the lateral direction of the garment. The rail electrodes shown in fig. 4 are two or three (not shown). The electrodes are in direct contact with the skin of the user when the user wears the electrocardiograph garment 140. The electrodes of the electrocardiograph garment are partially separated into non-conductive regions, so that two adjacent electrodes are insulated from each other. The non-conductive region corresponds to the position of the user's heart when the user wears the electrocardiograph garment 140. Therefore, when a user wears the electrocardiograph garment 140 and lies on the bed, the strip-shaped electrodes are communicated with the electrode contacts of the mattress, so that more effective electrocardiograph signals can be obtained due to the fact that the strip-shaped electrodes have a larger human body contact area. When three electrodes are used, the third electrode at the bottom is in contact with the lower limb of the user and is connected to the right leg drive circuit in order to reduce the common mode signal of the detection system.

Alternatively, the user may operate the control assembly 120 to select which of the electrocardiograph garment 140 and the electrocardiograph mattress 130 to use for delivering the electrocardiographic signals while the system is in use. Optionally, the electrocardiographic mattress 130 has a plurality of electrocardiographic detection electrodes and a pressure sensor (not shown) wired to the signal collection assembly by wires embedded in the mattress, and the pressure sensor transmits a signal to the signal collection assembly upon detection of a pressure change so that the signal collection assembly breaks wireless connection with the electrocardiographic collection box of the electrocardiograph garment and establishes a wired electrocardiographic detection electrical connection with the electrocardiographic mattress so that the signal collection assembly receives the plurality of electrocardiographic detection electrodes to acquire the user electrocardiographic signal.

As shown in fig. 2, the home ward unit managed by the home ward unit management system 100 according to the present disclosure further includes a blood pressure detection unit 160, which is a non-invasive blood pressure calibration component. The signal collection assembly 110 has an internal air pump (not shown) that inflates and pressurizes an external blood pressure cuff in the blood pressure detection unit via an air duct on the side of the signal collection assembly 110 and discharges air when the blood pressure detection unit 160 is activated by being connected to one of the multiple signal collection interfaces, so that a pressure sensor built in the signal collection assembly 110 obtains a blood pressure cuff pressure change through the air duct to perform blood pressure detection and blood pressure calibration for a user. Thus, the signal aggregation component 110 collects blood pressure parameters of the user via the interface and sends the detected blood pressure parameters to the control component 120 for data processing, display, storage. Although the blood pressure cuff shown in fig. 2 is a blood pressure cuff that is connected to the BSB 110, it may be a separate bluetooth cuff sphygmomanometer, with which the BSB 110 controls the bluetooth cuff sphygmomanometer via bluetooth.

As shown in fig. 2, since the components constituting the home ward unit managed by the home ward unit management system 100 are not present in the same circuit system, the system clock of each independent circuit system is not uniform, and thus, when a plurality of parameters are collected and need to be integrated, there are cases where the time axes of the plurality of parameters cannot be aligned. For the units wired to the signal collection block (BSB) 110, the same clock oscillator may be used, or the same clock oscillator may be used to obtain synchronization information by frequency division, frequency multiplication, or the like. For wireless devices such as WPO, due to the use of independent oscillators and inconsistent turn-on occasions, the synchronization signals can be acquired wirelessly using independent 2.4GHz or other frequencies. For example, a synchronization signal generator may be provided in any one of the units or a separate synchronization signal generator may be provided, with a synchronization time stamp being sent for each unit. After receiving the synchronous frame, each unit clears the frame count in the own circuit, and splices the synchronous time stamp into the data packet acquired by the unit. After the signal collection component 110 collects all the collected physiological signal parameters over a fixed time period, the physiological signal parameters over the period are time-axis aligned according to the time stamps and the aligned various parameters are sent to the control component for processing.

Although the synchronization signal generation unit (not shown) may be disposed on any constituent unit, it is most convenient to integrate the synchronization signal generation unit on WPO.

Although time alignment of the individual units using time stamps is mentioned here, time alignment may also be performed by calculating the delays of the individual signals. This alignment is known in the art and will not be described in detail again.

Fig. 5 is a block diagram illustrating an embodiment of multi-source signal synchronization by the control component 120 in the home ward unit management system according to the present disclosure. As shown in fig. 5, the plurality of signal acquisition devices constitute multiple signal sources of the control assembly 120, such as an electrocardiograph 140, an oximetry sensor 150, etc., identified as a master signal source a, a slave signal source B, a slave signal source C, respectively. Although fig. 5 shows only two slave signal sources B and C, in practical applications, there may be more signal sources for collecting various signals that need to be synchronized. The host signal source A comprises a Bluetooth BLE communication function, is communicated with the slave signal source, receives signal data collected by the slave signal source, and simultaneously transmits wireless synchronization configuration parameters to the slave signal source. Host signal source a also includes a 2.4GHz wireless transmitter (or transceiver) independent of bluetooth BLE as a wireless synchronization source. The master signal source a may also perform parameter configuration and signal reception and transmission with the slave signal sources B and C in a wired manner. The slave signal source also comprises a Bluetooth BLE communication function, communicates with the host signal source, transmits the acquired signal data to the host signal source, and simultaneously receives the wireless synchronous configuration parameters transmitted by the host signal source. The slave signal source also comprises a 2.4GHz wireless receiver (or transceiver) independent of bluetooth BLE, which receives the wireless synchronization signal. Both bluetooth BLE and 2.4GHz wireless may be implemented using prior art techniques, and thus are not described in detail herein. As described above, the present disclosure uses bluetooth BLE to transmit data, and other wireless communication methods or wired communication may be used to transmit the acquired signals. The synchronous mark can be sent by adopting a public frequency band of 2.4GHz, other frequency bands such as 433MHz and the like or wired direct connection according to the situation. The synchronization source transfer time (delay) needs to be well below the data synchronization error requirement (at least by an order of magnitude to ensure accuracy). The synchronization source minor delay relative to the data synchronization error can be directly ignored. The delay error which is unchanged to a certain extent can be deducted when the host data is processed. In view of power consumption, intermittent operation mode synchronization is used.

The master signal source a sends to the slaves signal sources B and C via bluetooth BLE: RTC (Rea Time Clock) timing beacons (accurate to seconds) or sync marks, parameter configuration by 2.4GHz wireless and logical configuration parameters by 2.4GHz wireless synchronization. The 2.4GHz wireless configuration parameters include a 2.4GHz frequency band and a channel address, and are used for designating a master-slave 2.4GHz wireless channel and switching the wireless channel when signals are interfered. The 2.4GHz synchronous logic configuration parameter comprises a 2.4GHz intermittent synchronous period (T), a time (T1) for opening the 2.4GHz time service information receiving unit 20 in advance before 2.4GHz synchronous triggering, and a time (T2) for overtime synchronous receiving of the 2.4GHz time service information receiving unit 20. In this way, the RTC information is sent out through the Bluetooth BLE to perform first-stage time service, so that clock difference of the master and slave machines cannot be excessively large due to long-time accumulation, the time when the slave machines open the transceiver and the time service of the master machines are completely staggered, and the master machines are never synchronized. After primary time service, in the time period that the transceiver of the slave is opened, the master sends out a synchronous mark through the 2.4GHz module to make a mark with higher precision, and the software implementation is to make a mark in a data packet directly through interruption when the receiving module receives information, wherein the precision is in milliseconds or less. Because of the general processor chip, the reading accuracy of the RTC module is not obtained in smaller units such as 1 second, milliseconds, etc. Therefore, the Bluetooth BLE is adopted to send out the RTC, and then the marking with higher precision is carried out, so that the synchronization among multiple signals is more accurate. Considering information processing instantaneity, the current 2.4GHz module only needs to send out a synchronous mark. Alternatively, the 2.4GHz module may of course issue a synchronization mark that also contains RTC time information and higher accuracy time information.

The time service information transmitting unit 10 of the master signal source a first performs RTC time service to the slave signal sources B and C. The accuracy is within 1s considering the transmission time and the like. The master signal source A and the slave signal sources B and C start timing according to the received RTC. Before reaching the configured intermittent synchronization time (T), the 2.4GHz timing information receiving units 20 of the slave signal sources B and C start waiting signals in advance by T1 time, so that the timing information receiving units 20 are started in advance to prevent the master signal source a and the slave signal sources B and C from not receiving the synchronization mark signals in time when the respective clocks of the master signal source a and the slave signal sources B and C have large differences. The master signal source A starts the 2.4GHz transmitter to transmit the synchronous marking signal when reaching the appointed time (T), and the slave signal sources B and C mark the corresponding positions of the acquired data after receiving the synchronous signal by the time service information receiving unit 20. If the 2.4GHz time service information receiving unit 20 of the slave signal sources B and C does not receive the synchronous mark signal, the 2.4GHz time service information receiving unit 20 is automatically closed after the timeout time t 2.

The host side transmits communication configuration parameters and synchronization logic configuration parameters, such as frequency band and channel addresses and synchronization period T, to itself and a signal acquisition unit (not shown) of the slave side through wireless communication (e.g., a wireless channel of 2.4 GHz) or a wired channel. The MAC address and frequency band is typically that of a 2.4G synchronization device. The communication units of the master machine side and the slave machine side can be wireless communication units or wired communication units, and can be selected according to actual needs, specifically, a time service information receiving unit 20 and a time service information transmitting unit 10. Although the time service information receiving unit 20 is named as a receiving unit, it may also transmit information, and the time service information transmitting unit 10 is named as a transmitting unit, it may also receive information.

After verifying or unifying the MAC address and the frequency band of communication among all the system constituent units, the time service information transmitting unit 10 simultaneously transmits a synchronization frame (synchronization signal) to a plurality of slave signal sources at time intervals of T seconds. Specifically, the master side and the slave side can count time based on independent constant pulses of the master side and the slave side, and determine whether to send time service information or whether to start to receive the time service information based on a certain rule. The host determines once per second whether a time service beacon transmission period T has elapsed. Specifically, a timer (not shown) calculates the remainder y, y= (tN-T0)% T once per second, where tN is the current timestamp of the host signal source, is the current timestamp of the host signal source alone, and T0 is the zero point timestamp after the host signal source is turned on. This is the total time elapsed after the host was turned on (tN-t 0). Calculated every second. When the remainder y is zero, it indicates that the time passes by an integer multiple of the time service transmission period T, and therefore, an instruction is issued to the time service information transmission unit 10 so that the time service information transmission unit 10 timely transmits time service information, that is, synchronization information. Meanwhile, a timer (not shown) at the slave end calculates a remainder y, y= (tN-t0+t1)% T once every second, where tN is a current timestamp of the slave signal source, is a current timestamp of the slave signal source alone, and T0 is a zero point timestamp after the slave signal source is turned on. Thus, (tN-t 0) is the total time elapsed after the slave was turned on, and (tN-t0+t1) is the time the slave is advanced by t1 compared to the actual time elapsed, calculated every second. When the remainder y is zero, it indicates that the time passes by an integer multiple of the time service receiving period T, and thus, the time service information receiving unit 20 is turned on, so that the time service information receiving unit 20 is turned on in time, and waits for receiving the time service information, that is, the synchronization information. And the time service information receiving unit 20 is turned off immediately after receiving the time service information and waits for an on signal transmitted again from the timer. And, the timer monitors the on time at the same time, and if the time service information is still not received after the predetermined time t2 is started, the time service information receiving unit 20 is directly instructed to be turned off. Specifically, the timer calculates the remainder y2, that is, y2= (tN-T0-t2+t)% T once per second in the communication unit on state, and if the remainder is zero, it means that the time service information receiving unit 20 is on and the duration of not receiving the time service information has reached T2. Although the calculation is mentioned once per second in the timing process, the calculation interval may be adjusted according to actual needs, for example, 0.5 seconds, 1.5 seconds, or 2 seconds, mainly according to the synchronization mark transmission interval period T.

When the slave signal source receives the synchronous mark, the position of the point which is instantly acquired by the received synchronous mark is marked on the waveform acquired by the slave to become a synchronous point, and the synchronous point is transmitted to the signal collecting component 110 along with the data packet where the synchronous point is located. Because the sampling precision of each signal source is independent of each other, the number of signals acquired in the same objective time interval is unequal. For example, the clock precision of the host a, the slave B, and the slave C is consistent with that of the host a and the slave B. Slave a samples 250hz for 1 second with 250 data points. The slave B clock precision is-0.4% relative to the master A, i.e. 249 data points are acquired in 1 second. If the clock marks of the master and the slave are not processed synchronously, the host receives the data problem point: 1. because of the accumulated error, the slave B, C is in fact inconsistent with each packet start, the longer the run time the greater the variance; 2. the slave data length received by the master unit time is inconsistent. For the above case, returning to fig. 2, the signal synchronization processing unit 40 performs synchronization processing on the received signals of the plurality of signal sources.

First, the synchronization processing unit 40 extracts a synchronization mark from the data collected by the signal aggregation component 110 and sent back from the slave B, C, and aligns B, C the data header with the synchronization mark as a starting point. Specifically, each received waveform is aligned according to the corresponding synchronous mark, so that the purpose of waveform synchronization is achieved.

Subsequently, the synchronization processing unit 40 performs a stretching or pressing process on the signals of which the number of sampled data is not equal. Specifically, for the case where there are still multiple points of waveform differences after synchronization (due to minor errors in time pulses of different devices), the waveforms are processed using a stretching or squeezing algorithm so that the processed waveforms can be aligned. For example, the signal of the slave C, which is to acquire 250 data points and only 249 data points, is subjected to linear interpolation processing to be stretched into 250 data points.

Likewise, if there are many data points, for example 251, at the sampling rate of the slave C, the squeezing process is required. The synchronous processing unit 40 obtains data C 'with the same length as the slave B through extrusion calculation, and sends B [250] and C' [250] to subsequent calculation for required processing. It should be noted that the interpolation may use various mathematical interpolation methods depending on the actual signal characteristics, and is illustrated here only by the simplest linear interpolation. Other extrusion methods can be adopted in the same way. The method and the device not only can correct the influence caused by clock errors of all components of the system, but also can solve the problem that sampling rates used by different slaves are inconsistent.

It should be noted that the chip 24L01 is used in all units involved in signal acquisition and transmission. nRF24L01 is a monolithic wireless transceiver chip manufactured by NORDIC operating in the ISM band of 2.4 GHz-2.5 GHz. The wireless transceiver includes: the setting of the frequency generator, the enhanced 'Shkburst' mode controller, the power amplifier, the crystal oscillator, the modulator and the demodulator, and the output power channel selection and the protocol can be set through the SPI interface. Almost can be connected to various singlechip chips and complete wireless data transmission work. Although a 24L01 chip is described as an example, other chips having the same function may be used, which is not illustrated herein.

The sync mark generated and issued by the time service information transmitting unit 10 is sometimes also referred to as a beat signal, a time stamp, a time header, a second sync header, or a sync mark. The timing information transmitting unit 10 transmits a signal through a radio frequency of 2.4GHz, and may transmit the synchronization signal through other wireless channels as long as the object of the present disclosure can be satisfied. The sync mark is sent once for one second in a period T, with only one byte of data. The synchronization mark may be a fixed data synchronization frame, or may be a synchronization frame containing a number, or may be an absolute time of the self-operation of the time service information transmitting unit 10, which contains a current time of microseconds of year, month, day, and time, and second, for example, 50 milliseconds of 35 minutes, 10 seconds, and 50 milliseconds of year, month, 12, month, 26, day, 22, and point 2016. Alternatively, the synchronization frame may also contain both the frame number and the current absolute time. When a synchronization frame is transmitted and received in the system, there is typically a small transmission delay, which is negligible for the technical solution of the present disclosure. However, it should be noted that the delay may be calculated when loading the synchronization frame in order to accurately load the synchronization frame, i.e. to subtract the transmission delay from the slave signal source. Since the calculation of the data transmission delay belongs to the prior art, it is not described here.

After the master signal source or the slave signal source obtains the synchronous mark, the collected signal marks the position of the point instantly collected by the received synchronous mark to become a synchronous point, and the synchronous signal is encoded or loaded into the collected signal or data packet. Due to the different clock accuracy of the devices, there may be a case where the number of sampling points is insufficient or excessive within one synchronizing mark range. The number of the synchronizing mark can be cyclically reused with a certain cyclic period. As described above, after receiving the sync mark from the source, the sync mark is loaded into the acquired signal or data packet during the same sync period T. Because the slave data packets are mixed with the synchronizing marks, the slave signal sources can send signals to the signal aggregation component 110 out of order, and the signal synchronization process can also order and align the data packets of different signal sources based on the synchronizing marks.

Optionally, returning to fig. 5, as shown in fig. 5, the host signal source a further includes a period updating unit 50. After the data of the slave machine is received in a complete period, the master machine signal source A performs data stretching or extrusion processing, the system response is long (at least one complete period is required to acquire two values of 250 and 249 of the B, C slave machine in the above example), and meanwhile, a large amount of storage space is occupied because the data of the slave machine in the complete period is received for reprocessing. Therefore, how to perform data processing in small batches continuously helps to eliminate the need for large storage space and can shorten the system response time. To this end, the system of the present disclosure also provides a period updating unit 50. After the system has been operated for a period of time based on the initial synchronization period T1, errors are obtained for different slave signal sources based on the acquired data acquired by the respective slave signal source B or C, e.g. the slave signal source C has acquired only 249 data points due to the acquisition of 250 data points. Thus, the error is determined to be constant for a predetermined time. For this purpose, the period updating unit 50 may shorten the synchronization period T1 to the synchronization period T2, but the signal synchronization processing unit 40 still uses the previously known sampling error result of the slave signal source C to stretch and squeeze the signal data of the sampling data received in the synchronization period T2. Typically T2 is half of T1. Alternatively, T1 is an integer multiple of 2 of T2. Thus, the data from the source C is processed queue first to queue first using the previously measured error values. Specifically, if t1=2t2, the same sync mark may be repeatedly transmitted twice in the entire period of T1, so that it is not necessary to wait for all data of one complete period T1. Since in a typical system the error of the system clock under fixed ambient conditions is substantially constant (unless temperature changes sharply lead to clock drift; there is no drift problem at all if a high stability clock such as a temperature compensated crystal oscillator is used). By obtaining partial data within one complete T1 period in this way, the space in which the signal aggregation component 110 or the signal synchronization processing unit 40 performs data storage can be reduced by T2/T1, and the time required for calculation can be reduced to T2/T1, and the buffer occupancy can be reduced by T2/T1. In addition, when the environment changes, the system discovers that the slave clock drifts, and the master can configure the intermittent synchronization period T at any time or at regular time to correct errors.

Fig. 6 is a block diagram illustrating a home ward unit managed by the home ward unit management system according to the present disclosure. The control component 120 uses STM32F407 as a core control unit, adopts a 16-bit CPU bus to be connected with a liquid crystal display unit 105 (for example, a 2.4-inch liquid crystal screen is connected, the liquid crystal display unit 105 can display an electrocardio waveform, a blood oxygen pulse wave waveform, a heart rate, blood oxygen saturation, a blood pressure measured value, a body temperature, a battery level of a family ward unit, a disconnection and connection state of a WIFI and Bluetooth of the family ward unit and the like, the blood pressure detection unit 160 (FPGA) adopts an 8-bit I/O bus to be connected with the CPU of the control component 120, and calculates continuous blood pressure by using the electrocardio waveform input by the electrocardio garment 140 and blood oxygen waveform data input by the blood oxygen detector 150.

When the key is pressed, the key control unit 110 of the control assembly 120 scans the low level state of the I/O port by the CPU, and determines that the key is pressed. Bluetooth unit 515 interacts with the CPU of control component 120 via a serial port using a bluetooth communication protocol of 4.0. The WIFI unit 510 uses a 2.4ghz, ieee802.11 wireless lan communication protocol, and interacts with the control component 120CPU through a serial port. The blood oxygen detector 150 receives the measured signals from the blood oxygen probe 151 to measure pulse wave and blood oxygen saturation, and interacts with the CPU of the control assembly 120 through a serial port. The electrocardiograph garment 140 acquires electrocardiographic signals of the user. The amplified analog electrocardiographic signal is fed to an analog-to-digital sampling port of the CPU of the control component 120, whereby electrocardiographic waveforms are acquired, and the acquired electrocardiographic waveforms are displayed on the display unit 105.

The home ward unit management system of the present disclosure may further include a body fat unit 525. The body fat unit 525 injects an ac constant current through the external electrode, the CPU of the control unit 120 collects an ac root mean square voltage of the human body, calculates an ac impedance Rac, and calculates a fat content of the human body.

The electrocardiograph garment 140 of the present disclosure also includes a body temperature unit. The body temperature unit can be an electronic thermometer, which senses the surface temperature of a human body by using a thermistor, and amplifies and collects the variation of the resistance value of the thermistor by using an operational amplifier, thereby calculating the temperature of the human body. The body temperature unit sends the detected body temperature to the CPU of the control assembly 120 through the bluetooth chip in the signal acquisition box of the electrocardiograph garment 14 and the bluetooth unit through the bluetooth 4.0 protocol, and displays it to the user on the display unit 105. The home ward unit of the present disclosure also includes a temperature and humidity module that measures the temperature and humidity of the environment and interacts with the CPU through the HDQ protocol.

The blood pressure detection unit 160 of the home ward unit managed by the home ward unit management system of the present disclosure measures the blood pressure of the human body using the korotkoff sound principle, and interacts with the CPU through the serial port. In addition, the home ward unit of the present disclosure further includes a temperature and humidity unit (not shown) that can measure the temperature and humidity of the environment, interacting with the CPU through the HDQ protocol. It should be noted that, when blood pressure detection is performed, the blood pressure detection unit 160 generally performs blood pressure calibration. When the home ward unit management system is used for the first time, the mobile phone client prompts the user to calibrate the cuff blood pressure. The blood pressure calibration is to send out a blood pressure calibration command through the mobile phone client, and the home ward unit management system performs approval operation after receiving the calibration command. If the current time exceeds 7 days (which can be set to 3 days, 5 days or 14 days) from the last blood pressure calibration time, the home ward unit management system prompts 'blood pressure needs to be calibrated' after being started. The continuous blood pressure calibration is usually performed by collecting blood pressure parameters of arm cuffs of a human body. After the calibration is successful, the home ward unit sends a success state to the mobile phone client. The mobile phone client and the home ward unit record the calibration time and the result at the same time, and prompt the user to calibrate again after 7 days. The blood pressure is calibrated in order to calibrate the continuous blood pressure. Alternatively, the client may be integrated in the control component 120 and displayed in the display unit. Therefore, under the condition that a mobile phone client is not provided, the blood pressure calibration can be automatically performed, the user is prompted to perform the calibration, and the calibration operation is automatically completed.

The home ward unit as described above is a device for comprehensively measuring various vital sign parameters of a human body, such as blood oxygen measurement, heart rate monitoring, blood pressure trend monitoring, electrocardiographic monitoring, body temperature monitoring, health index BMI monitoring, body fat monitoring. The vital sign data of the user can be automatically uploaded to the cloud server through the special mobile communication client through WiFi and stored for a long time. For the data that has been uploaded, the user may pay for, consulting the doctor about the user's health through the cloud service. The household ward unit can support the use of multiple people in a household, can record abnormal sign data in time, and is convenient for treatment of a doctor. The client of the household ward unit can conduct intelligent data analysis and data cloud storage.

The clients are typically various mobile phone clients APP or PC clients APP. In the related art, a user remotely controls the intelligent terminal device through a client APP installed on a subscriber unit, and the remote control can be realized through wireless radio frequency technologies such as bluetooth, iBeacon, near field communication (Near Field Communication, NFC), non-contact radio frequency identification (Radio Frequency Identification, RFID) and the like.

In the case of such a one-to-one type of monitoring device and home ward unit, as mentioned above, when the intelligent monitoring device is shared by several persons, this results in all data of the monitoring device being transmitted to the client of the home ward unit of the administrator user, and therefore all users sharing the monitoring device will not be aware that those data in the data obtained by the monitoring device are data belonging to themselves, nor can they obtain accurate historical data of themselves. With the development of society, people pay more attention to their health, and therefore pay more attention to their physical indexes. One or more monitoring devices or monitoring apparatuses are thus prepared at home to facilitate frequent checking or monitoring of their physiological indexes, thereby guiding their daily life activities based on the daily detection or monitoring results. It is obvious that it is wasteful for a household to have an identical monitoring device for each member, and therefore it would be a great convenience for all members if an account could be configured for each household member or for each member of a collection under the same monitoring device. To this end, in order for a plurality of users to share the monitoring devices in each home ward unit, the home ward unit management system according to the present disclosure is capable of providing a sub-user account for each monitoring device to each home ward unit owner.

Returning to fig. 1, the home ward 01, 02, 03, … N managed by the home ward management system according to the present disclosure may be connected to a cloud server of a provider of the monitoring device through the internet. The internet may be replaced by a communication network or may be a mobile internet. The provider cloud server may be any other web server. The monitoring device as described above may be any intelligent monitoring device such as a blood pressure meter, blood glucose meter, fetal heart monitor, body temperature monitor, body weight and body fat monitor, blood oxygen monitor, ECG monitor, urine monitor, body index monitor, and other monitoring devices having the function of detecting physiological parameters of the human body. The monitoring device can be provided with a built-in wireless communication unit, and can perform data transmission and information interaction with other equipment in Bluetooth, wifi, GPRS and 3G/4G communication modes, and can also perform data transmission and information interaction with other equipment in a wired communication mode. The monitoring device may be an electrocardiograph or a sphygmomanometer. In general, a user of a home ward unit registers an administrator user account by logging into a login registration application client provided by a monitoring device vendor before or after purchasing the monitoring device. The various data generated by the monitoring device is then recorded under the account of the logged-in user by binding the unique Serial Number (SN) of the monitoring device that has been purchased with the administrator user account. In the event that a user of an administrator user account may log into a client, one or more child user accounts affiliated with the administrator user account may be registered based on identification numbers (IDs) of home ward units of other users. The sub-user account can be logged in through the client, and when the monitoring device is connected to the home ward unit of the sub-user account, data from the monitoring device is received, and the data is recorded under the corresponding sub-user account. Meanwhile, the data of the sub-user account can also be transmitted to a cloud server through the Internet for storage.

A home ward unit may contain an administrator user account and a plurality of sub-user accounts. The users of the administrator user account and the sub-user account log in through the family ward unit and use the monitoring device, and the data are directly stored in the monitoring device or transmitted to the cloud server.

And establishing Internet access by starting a client of the home ward unit. If the user does not have an account, the user may enter an administrator user registration page and perform an administrator user registration process. If the user has an account, the default login administrator user page can be selected to login the administrator user account, and the sub-user account registration login state can be selected to register the sub-user account. The administrator user account can perform management operation on all data of the administrator user own account and the affiliated sub-user accounts. In addition, after the user logs in the sub-user account, the data of the sub-user account can be managed.

The registration process of the administrator user account is performed in a conventional registration manner, and the user identity information includes, but is not limited to, one or more of a mobile phone number, an E-mail, and an identity card number. Registration is accomplished by a registration authority, such as a monitoring device management system, sending a verification code to the user's handset to register and verify the uniqueness of the user ID. If the server registration mechanism judges that the user registration does not exist in the data table, the user submits the registration information to the server registration mechanism for processing after inputting the user ID, the password and the verification code in the registration window until the registration is successful. After registration is completed, an account management page of the administrator user is entered, and in the management page, the administrator user can manage the sub-user accounts under the account and the bound monitoring device through the management page.

In the login and registration process, the home ward unit performs user identity authentication, user password and information modification, and uses the unique ID of the user as the unique identification standard of the user and corresponds to the background server device. After a user logs in a client of the home ward unit, the home ward unit is automatically identified and connected with the monitoring device through the communication unit according to the binding of the user before, and is initialized, set and stored.

Typically, in the use of monitoring devices by users, one monitoring device is used intelligently by one user in a one-to-one manner, in order to prevent the occurrence of data ownership confusion. Thus, in order to enable a monitoring device to be shared among multiple users within a small group (e.g., within a home), a sharing mechanism may be provided. First, as described above, if an administrator user account exists, login and registration operations of sub-user accounts are performed in the login and registration page of non-administrator user accounts. Identity information (e.g., a user communication identification, such as a SIM card number) and a password for the sub-account number are entered, and then a registration button is clicked. The multi-user management component in the registration server (which may be the same server as the monitoring device vendor server) obtains one or more user communication identifications entered by an administrator user through the home ward unit and sends a verification code to a communication device to which the one or more user communication identifications belong through the communication network. And inputting the verification code in the administrator user page and sending the verification code to the registration server. It should be noted that, the administrator user may directly obtain the received verification code from the home ward unit of the one or more user communication identifiers, or the registration server may send the verification code of the sub-account to be registered to the home ward unit of the administrator user at the same time. The multi-user management component verifies the obtained verification code so as to generate one or more sub-user accounts affiliated to the administrator user account, thereby establishing a sub-account under the administrator user account, automatically binding the sub-account under the administrator user account, and simultaneously transmitting all information of the sub-user account to the monitoring device provider server through the administrator user account. Alternatively, multiple sub-user accounts under an administrator user account may also be formed directly at the home ward unit without the need for a verification step. That is, the registration of the sub-user account is performed locally at the home ward unit of the administrator user. Particularly, when the monitoring device system is built in the home ward unit, under the condition that the administrator user logs in, the registration process of the sub-user accounts can be used for directly generating a plurality of sub-user account user names and giving passwords under the administrator user accounts without performing a verification process.

Then, it is determined whether the administrator user needs to bind the monitoring device on the child user account. If the monitoring devices need to be bound for the child user account by the selection of the administrator user, the client displays the Serial Numbers (SNs) of all monitoring devices bound to the administrator user account. And then, the administrator user selects corresponding serial numbers from serial numbers of all monitoring devices under the administrator user account, and the first binding component imports the serial numbers of the selected monitoring devices into a parameter table of the sub-user account based on the selection of the administrator user, so that terminal equipment of the selected serial numbers is bound under the sub-user account.

An administrator user may add a monitoring device to the client of the home ward unit. The communication module in the home ward unit detects whether a new intelligent monitoring device (an intelligent monitoring device different from the serial number of the existing monitoring device under the account of the administrator user) exists in the detection range of the communication module through Bluetooth, wifi, GPRS and 3G/4G communication modes. If a new intelligent monitoring device exists (i.e., a new serial number), the obtained serial number of the new monitoring device is sent to the monitoring device verification component at the registration server. If there is no new smart monitoring device (i.e., a new serial number) (e.g., a newly purchased smart monitoring device is not on), the client of the home ward unit will pop up the monitoring device serial number entry field, whereby the administrator user can enter the serial number of the newly purchased smart monitoring device into the entry field, whereby the obtained serial number of the new monitoring device is sent to the monitoring device verification component at the registration server. The monitoring device verification component at the registration server obtains serial numbers (i.e., identification of the monitoring devices) from one or more monitoring devices of the home ward unit and compares the serial numbers of the bound monitoring devices to verify whether the identification of the one or more monitoring devices is bound. Finally, the second binding component 16 binds the identity of the unbound monitoring device to the administrator user account. In this way, an administrator user may bind multiple monitoring devices under their administrator user account.

In some embodiments, after the monitoring device completes binding with the administrator user account and the plurality of sub-accounts, when the account is used, the specific login window and the registration window may be set as the administrator user account login or the sub-account login by default, which is not limited by the embodiment of the present disclosure. However, when the user is a user of the sub-user account, the user needs to input an administrator user account in addition to the user name and password of the sub-account and the verification code, and the sub-account can be successfully logged in.

In the event that an administrator user logs in, the administrator user may manage sub-user accounts under his account, such as adding or deleting sub-user accounts and binding the sub-user accounts to some monitoring device. And checking the condition of the sub-user accounts under the manager user account. Without a child user account, a child user account may be added.

A home ward unit management system according to the present disclosure is described above in detail. As described above, a user may establish a different user for each bound device when configuring parameters for the monitoring device; each user has different parameters for different devices, and thus a table of configuration parameters is stored in each user's home ward unit. The parameter table may also be stored at the cloud server. These parameters are, for example: device serial number, user account number, user profile (such as height, weight, gender, age), etc. The administrator user sets the mobile phone number and the password for each user through registration, so that the user logs in and inquires own data. An administrator user may manage all devices and all user information, while each non-administrator user may query his own real-time data (such as pulse rate, heart rate, blood oxygen saturation, systolic pressure, diastolic pressure, body movement amplitude, pressure values) and historical data on the monitoring device and configure his own parameters in the device.
