FIG. 4 is a schematic diagram of an electrocardiographic suit 140 of a family ward unit managed by the family ward unit management system according to the present disclosure. As shown in Figure 4, the electrocardiographic suit 140 includes an electrocardiographic collection box that is wirelessly connected to the signal collection assembly arranged on it, which is buckled on the electrocardiographic signal collection seat 147 and arranged inside the electrocardiographic suit. A pair of differential signal electrodes corresponding to the upper and lower positions of the human heart and a reference electrode arranged on the inside of the electrocardiographic suit below the differential signal electrodes. The differential signal electrode and the reference electrode are connected so as to obtain the user's electrocardiogram signals obtained by the first, second and third electrocardiogram collection electrodes and wirelessly transmit them to the signal collection component. Specifically, the ECG clothing 140 is a thin clothing material whose main material is non-conductive. The ECG clothing includes a first ECG collecting electrode (on the back shoulder), a second ECG collecting electrode 148 and a third ECG collecting electrode 149 . The first ECG collection electrode, the second ECG collection electrode 148 and the third ECG collection electrode 149 are the first, second and third ECG collection electrode strips respectively, that is, the ECG collection electrode is a strip shaped electrodes. The first electrocardiogram collecting electrode and the second electrocardiogram collecting electrode 148, as a pair of differential signal electrodes, are respectively arranged at the upper and lower ends corresponding to the position of the human heart on the inner side of the electrocardiogram clothing, so as to obtain the differential heart rate of the upper and lower ends of the human heart position. electric signal. Specifically, the first electrocardiographic collection electrode is arranged as a differential signal electrode on the inner side of the electrocardiographic suit 140 above the position corresponding to the heart of the human body. The second electrocardiogram collecting electrode 148, as another differential signal electrode, is arranged on the inner side of the electrocardiogram suit below the position corresponding to the heart of the human body. The third electrocardiogram collecting electrode 149 is used as a reference electrode, and is arranged on the inner side of the electrocardiogram suit below the second electrocardiogram collecting electrode 148 . On the electrocardiographic suit 140, there is also an electrocardiographic signal collecting seat 147, which is located on the outside of the electrocardiographic suit at a position different from that of the first, second and third electrocardiographic collecting electrodes. The ECG signal collection base 147 includes three electrode buttons, such as a first electrode button 141 , a second electrode button 142 and a third electrode button 143 as shown in FIG. 4 . The first electrode buckle 141 faces the inner side of the electrocardiographic suit by insulating the first lead 144 embedded in the electrocardiographic suit and the first electrocardiographic collection electrode, and the second electrode buckle 142 is embedded in the heart by insulating the side facing the inner side of the electrocardiographic suit.

Like this, the first electrocardiogram collecting electrode, the second electrocardiogram collecting electrode 148 and the 3rd electrocardiogram collecting electrode 149 transmit the electrocardiogram signal collected from the human body surface to buckle-mounted electrocardiogram signal collecting seat respectively through the lead connected respectively. Corresponding first electrode button 141 , second electrode button 142 and third electrode button 143 on the top. A pair of corresponding electrocardiographic signal acquisition boxes (not shown) are buckled on the electrocardiographic signal collection seat 147, and the first electrocardiographic signal acquisition box is provided with the first electrode button 141 and the second electrode button 142. And the electrode button corresponding to the third electrode button 143 . When the first electrode button 141, the second electrode button 142 and the third electrode button 143 are male buttons, the electrode buttons in the ECG signal collection box are female buttons; otherwise, when the first electrode button 141, the second electrode button 142 And when the third electrode button 143 is a female button, the electrode button in the first ECG signal collection box is a male button. Although it is shown here that the electrocardiographic signal collecting seat 147 includes three electrode buttons, three electrical contacts can also be used. In this way, the corresponding electrocardiographic signal collection box also adopts three point contacts. After the ECG signal acquisition box receives the ECG signals transmitted by the three ECG acquisition electrodes through the ECG signal collecting seat, the ECG signal acquisition box collects the signals, and after filtering, amplifying, and denoising, real-time or centralized Wirelessly transmit to the back-end platform (mobile APP, supporting host, etc.) for analysis and storage, and can also store backups in the local memory. The back of the inner side of the ECG suit also includes a body temperature sensing unit, which senses the surface temperature of the human body through the thermistor and collects it into the signal collection component, so that the signal collection component amplifies the change of the collected thermistor resistance through the built-in operational amplifier The amount, from which the user's body temperature is calculated.

Return to Figure 2. As shown in Figure 2, the family ward unit managed by the family ward unit management system may also include an ECG mattress 130, which is used to detect the ECG signal of the user lying on the mattress, and the signal collection component is used for the ECG The interface of the electrical signal detection circuit is connected to three strip-shaped flexible electrodes so as to detect the user's electrocardiographic signal. When the user lies on the mattress 130 , the ECG detection circuit in the signal collection component 110 obtains ECG signals from the electrode contacts. The control component 120 forms an ECG electrocardiogram based on the electrocardiographic signal transmitted from the electrocardiographic signal detection circuit in the signal collection component. According to needs, the ECG signal detection circuit can also be directly arranged in the mattress and send the collected signal to the signal collection component 110 . The mattress shown in Figure 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, with conductive buttons on its side edges, used as ECG collection sensors respectively, these electrodes can be silver fiber electrodes. The second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth can be used as upper limb ECG electrodes, and the electrical signals collected from the human body by the electrode part of the fiber conductive cloth can be transmitted to the instrument amplifier through the lead detection circuit. In order to adapt to the collection of human chest ECG signals and leg signals, the width of the second part and the fourth part is 7 cm to 15 cm. 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 respectively located at both ends of the user's heart during use, and the distance between the upper end of the heart and the shoulder is limited. Therefore, the width of the electrodes is limited by this distance. On the other hand, within a certain range, the wider the electrode width, the larger the contact area between the electrode and the human body, and the clearer the waveform without clutter. For example, if the width of the electrode is less than 7 centimeters, the peak value collected by the mattress may be less than 1.0 volts, which will cause trouble to the validity of the measurement of the ECG signal parameters. On the other hand, the wider the width of the electrodes, the more material is required to manufacture the electrodes, which increases the manufacturing cost of the collection pad. Weighing the measurement result and cost, the width of the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth can be selected from 7 cm to 15 cm. Optionally, the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth have the same width. The inventor found through actual measurement that when the width of the second part and the fourth part are 9 cm, the peak value of the collected signal is about 1.7 volts after amplification processing, and this value is sufficient for the measurement of cardiac physiological parameters of. In addition, if the width of the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth continue to increase from 12 cm, the peak value does not increase significantly accordingly. Based on this, preferably, the width of the ECG collecting sensor A and the ECG collecting sensor B are preferably 9 cm to 12 cm. Therefore, the width of the electrocardiographic acquisition sensor A and the electrocardiographic acquisition sensor B is preferably 12 centimeters. As shown in Figure 2, the distance between 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 (that is, the third part and the fifth part) is 15 cm to 20 cm, the spacer part is made of cotton fabric. Theoretical and experimental data show that the distance between the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth has a significant impact on the measurement of the collected ECG signal. The second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth for collecting ECG signals are respectively located at the upper and lower ends of the heart to obtain the best signal quality. Spacing that is too wide or too narrow will result in too much clutter or too little amplitude in the signal. The distance between the electrodes of the ECG collection pad is preferably 15 cm, which is more suitable for the heart size of most people. At this distance, the peak of the waveform of the collected ECG signal is obvious, and the signal-to-noise ratio is large.

In addition, the length 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 is 70 cm to 100 cm, preferably 90 cm. As mentioned above, the human ECG signal is a weak electrical signal. ECG signals are usually interfered by various noises, such as interference from human motion. In this embodiment, the second part of the silver fiber conductive fabric, the fourth part of the silver fiber conductive fabric, and the sixth part of the silver fiber conductor are rectangular and integral. This allows the human body to turn over on the collection pad while keeping the human body in contact with the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth. The second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth are parallel to each other, and the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth are parallel to the head of the mattress. This makes the interval between the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth remain unchanged. In this way, the collection of ECG signals will not be affected by turning over when ordinary users sleep on this collection pad. Effectively guarantee the accuracy of the measurement results.

The sixth part silver fiber conductive cloth can be used as leg drive electrodes. The silver fiber conductive cloth in the second part, the silver fiber conductive cloth in the fourth part, and the silver fiber conductive cloth in the sixth part as the ECG acquisition circuit have larger areas, so the collected signal strength will be greater and the signal will be more stable.

In addition, the second part of the silver fiber conductive cloth and the fourth part of the silver fiber conductive cloth may include silver fiber conductive fabric, or copper-nickel alloy fiber conductive fabric. Conductive fabric is a conductor and can play the role of potential difference signal measurement. The conductive fabric can not only capacitively couple with the human body, but also because the conductive fabric is relatively thin and tough, it can also physically fit well with the body of the collection pad, which can make the collection pad more comfortable. In order to make the user lie on the collection pad more comfortably, the thickness 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 is 0.5 mm to 1.2 mm, preferably 1 mm, both It can maintain the conductivity of the electrode and the softness of the bed sheet.

Optionally, in order to improve the detection effect of the electrocardiographic signal, the user may be required to wear the electrocardiographic suit 140 during the detection, and the electrocardiographic suit 140 has a plurality of electrodes extending along the lateral direction of the garment. There are two or three horizontal strip electrodes shown in FIG. 4 (not shown). When the user wears the electrocardiographic suit 140, the electrodes are in direct contact with the user's skin. The part between the electrodes of the ECG suit is a non-conductive area, so that two adjacent electrodes are insulated from each other. When the user wears the electrocardiographic suit 140, the non-conductive area corresponds to the position of the user's heart. Thus, when the user is lying on the bed wearing the electrocardiographic suit 140, the strip electrodes communicate with the electrode contacts of the mattress, so that more effective ECG signals can be obtained because the strip electrodes have a larger contact area with the human body. When using three electrodes, the bottom third electrode is in contact with the user's lower extremity and is connected to the right leg drive circuit in order to reduce the common mode signal of the detection system.

Optionally, when using the system, the user can operate the control component 120 to select which one of the electrocardiographic clothing 140 and the electrocardiographic mattress 130 is used to transmit the electrocardiographic signal. Optionally, the ECG mattress 130 has a plurality of ECG detection electrodes and pressure sensors (not shown), which are wired to the signal collection assembly through wires embedded in the mattress, and the pressure sensors detect When the pressure changes, transmit signals to the signal collection assembly so that the signal collection assembly cuts off the wireless connection with the ECG collection box of the ECG clothing and establishes a wired ECG detection electrical connection with the ECG mattress for signal collection The component receives multiple ECG detection electrodes to obtain the user's ECG signal.

As shown in FIG. 2 , the family ward unit managed by the family 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 a built-in air pump (not shown), and when the blood pressure detection unit 160 is connected to one of the multi-signal collection interfaces and is activated, the air pump passes through the air duct on the side of the signal collection assembly 110 Inflate and pressurize the external blood pressure cuff in the blood pressure detection unit, and discharge the gas, so that the pressure sensor built in the signal collection component 110 can obtain the pressure change of the blood pressure cuff through the airway tube to perform blood pressure detection and blood pressure calibration for the user. Thus, the signal collection 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, and storage. Although the blood pressure cuff shown in FIG. 2 is a blood pressure cuff connected to the BSB 110, it could be a stand-alone Bluetooth cuff blood pressure monitor that is controlled by the BSB 110 via Bluetooth.

As shown in FIG. 2 , since the components of the home ward unit managed by the home ward unit management system 100 do not exist in the same circuit system, the system clocks of each independent circuit system are not uniform, so the collected When multiple parameters need to be integrated, there are situations where the time axes of multiple parameters cannot be aligned. For the units connected with the signal pooling block (BSB) 110 by wire, the same clock oscillator can be used, or the synchronization information can be obtained by means of frequency division and multiplication of the same clock oscillator. For wireless devices such as WPO, due to the use of independent oscillators and inconsistent start-up timing, independent 2.4GHz or other frequencies can be used to obtain synchronization signals wirelessly. For example, a synchronization signal generator may be provided in any one of the units or a separate synchronization signal generator may be provided to send synchronization time stamps for each unit. After receiving the synchronization frame, each unit clears the frame count in its own circuit, and splices the synchronization time stamp into the data packet it collects. After the signal collection component 110 collects all the collected physiological signal parameters within a fixed time period, the physiological signal parameters within the period are time-axis aligned according to the time stamp, and the aligned parameters are sent to the control component for processing.

Although the synchronizing signal generating unit (not shown) can be arranged on any constituent unit, it is most convenient to integrate the synchronizing signal generating unit on the WPO.

Although it is mentioned here that time stamps are used to perform timing alignment of each unit, time alignment can also be performed by calculating the delay of each signal. This alignment method belongs to the prior art, so it will not be described in detail again.

FIG. 5 is a schematic block diagram of an embodiment of multi-source signal synchronization performed by the control component 120 in the family ward unit management system according to the present disclosure. As shown in Figure 5, a plurality of signal acquisition devices constitute the multi-signal sources of the control component 120, such as the electrocardiograph 140, the blood oxygen detector 150, etc., which are identified as the master signal source A, the slave signal source B, and the slave signal source respectively. Source C. Although Figure 5 only shows two slave signal sources B and C, in practical applications, there may be more signal sources for collecting various signals that need to be processed synchronously. The host signal source A includes the Bluetooth BLE communication function, communicates with the slave signal source, receives the signal data collected by the slave signal source, and 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 can also perform parameter configuration and signal reception and transmission with the slave signal sources B and C through wired methods. The slave signal source also includes the Bluetooth BLE communication function, communicates with the host signal source, transmits the collected signal data to the host signal source, and at the same time receives the wireless synchronization configuration parameters transmitted by the host signal source. The slave signal source also includes a 2.4GHz wireless receiver (or transceiver) independent of Bluetooth BLE to receive wireless synchronization signals. Both Bluetooth BLE and 2.4GHz wireless can be implemented using existing technologies, so details will not be described here. As mentioned above, the present disclosure uses Bluetooth BLE to transmit data, and other wireless communication methods or wired communication can also be used to transmit collected signals. The transmission of the synchronization mark can use the public frequency band 2.4GHz, and can also use other frequency bands such as 433MHz or wired direct connection according to the situation. The transmission time (delay) of the synchronization source needs to be much lower than the data synchronization error requirement (at least one or two orders of magnitude difference to ensure accuracy). The slight delay of the synchronization source relative to the data synchronization error can be directly ignored. A certain degree of constant delay error can be deducted when the host data is processed. Consider the power consumption problem and use the intermittent working method to synchronize.

Master signal source A sends to slave signal sources B and C through Bluetooth BLE: RTC (Rea Time Clock) timing beacon (accurate to seconds) or synchronization mark, parameter configuration through 2.4GHz wireless and 2.4GHz wireless synchronization logic configuration parameter. The 2.4GHz wireless configuration parameters include the 2.4GHz frequency band and channel address, which are used to specify the master-slave 2.4GHz in the wireless channel, and switch the wireless channel when the signal is interfered. The 2.4GHz synchronization logic configuration parameters include the 2.4GHz intermittent synchronization period (T), the time to turn on the 2.4GHz timing information receiving unit 20 in advance before the 2.4GHz synchronization is triggered (t1), and the time for the 2.4GHz timing information receiving unit 20 to receive synchronous timeout (t2 ). In this way, the RTC information is sent out through Bluetooth BLE for the first-level timing, so that the clock difference between the master and the slave will not be too large due to long-term accumulation, resulting in the timing of the slave turning on the transceiver and the timing of the master completely staggering each other. It will never be synchronized. After the primary timing, during the period when the transceiver of the slave is turned on, the master sends a synchronization mark through the 2.4GHz module to make a mark with higher precision. When the receiving module receives the information, the software implementation is to mark the data packet directly through the interrupt. Accuracy is in milliseconds or even smaller. Due to the general processor chip, the reading accuracy of the RTC module is 1 second, which cannot be obtained in smaller units such as milliseconds. Therefore, after the RTC is sent out by Bluetooth BLE, a higher-precision mark is used to make the synchronization between multiple signals more accurate. Considering the real-time nature of information processing, the current 2.4GHz module sends out a synchronization mark is only a mark. Optionally, of course, the synchronization mark sent by the 2.4GHz module may also contain RTC time information and higher-precision time information.

The timing information sending unit 10 of the master signal source A performs RTC timing to the slave signal sources B and C first. Considering transmission time, etc., the accuracy is within 1s. Master signal source A, 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 unit 20 of the slave signal source B and C turns on the waiting signal t1 in advance, and the timing information receiving unit 20 is turned on in advance to prevent the master signal source A, When the respective clocks of signal sources B and C of the slave machine differ greatly, the synchronization mark signal is not received in time. The master signal source A reaches the agreed time (T) and turns on the 2.4GHz transmitter to transmit the synchronization mark signal, and the slave signal sources B and C mark the corresponding positions of the collected data after the timing information receiving unit 20 receives the synchronization signal. If the 2.4GHz timing information receiving unit 20 of the slave signal source B and C does not receive the synchronization mark signal, after the timeout time t2, the 2.4GHz timing information receiving unit 20 is automatically turned off.

The master side sends communication configuration parameters and synchronization logic configuration parameters to itself and the signal acquisition unit (not shown) on the slave side through wireless communication (for example, a 2.4GHz wireless channel) or a wired channel, such as frequency band and channel address and synchronization period T et al. The MAC address and frequency band are usually the MAC address and frequency band of 2.4G synchronous equipment. The communication units at the master end and the slave end can be wireless communication units or wired communication units, which can be selected according to actual needs. Specifically, they can be the timing information receiving unit 20 and the timing information sending unit 10 . Although the timing information receiving unit 20 is named as a receiving unit, it can also transmit information, and the timing information transmitting unit 10 is named as a transmitting unit, and it can also receive information.

After verifying or unifying the communication MAC addresses and frequency bands among all system constituent units, the timing information sending unit 10 simultaneously sends the synchronization frame (synchronization signal) to multiple slave signal sources at intervals of T seconds. Specifically, both the host and the slave will perform timing based on their own independent constant pulses, and determine whether to send timing information or whether to turn on to receive timing information based on certain rules. The host side will judge once per second whether a timing beacon sending period T has passed. Specifically, a timer (not shown) calculates the remainder y once per second, y=(tN-t0)%T, where tN is the current timestamp of the host signal source, and is the unique current timestamp of the host signal source, t0 is the zero time stamp after the host signal source is turned on. Thus (tN-t0) is the total time elapsed after the host is turned on. Calculated every second. When the remainder y is zero, it means that the time has passed an integer multiple of the timing sending period T, so an instruction is sent to the timing information sending unit 10 so that the timing information sending unit 10 sends timing information, ie synchronization information, in time. At the same time, the timer (not shown) at the slave side calculates the remainder y once per second, y=(tN-t0+t1)%T, where tN is the current timestamp of the slave signal source, which is unique to the slave signal source t0 is the zero time stamp after the slave signal source is turned on. In this way (tN-t0) is the total time elapsed after the slave is turned on, and (tN-t0+t1) is the time t1 ahead of the actual elapsed time of the slave, which is calculated every second. When the remainder y is zero, it means that the time has passed an integer multiple of the timing receiving period T, so the timing information receiving unit 20 is sent to open, so that the timing information receiving unit 20 is turned on in time, waiting to receive timing information, that is, synchronization information. And the timing information receiving unit 20 is turned off immediately after receiving the timing information, and waits for the start signal sent by the timer again. Moreover, the timer monitors the opening time at the same time, and if the timing information is still not received after the predetermined time t2 is turned on, it will directly instruct the timing information receiving unit 20 to turn off. Specifically, the timer calculates the remainder y2 once per second when the communication unit is turned on, that is, y2=(tN-t0-t2+T)%T, if the remainder is zero, it means that the timing information receiving unit 20 is turned on and The duration of not receiving timing information has reached t2. Although it is mentioned above that the calculation is performed once per second in the timing process, the calculation interval can also be adjusted according to actual needs, such as 0.5 seconds, 1.5 seconds or 2 seconds, mainly based on the synchronization mark sending interval period T.

When the slave signal source receives the synchronization mark, on the waveform collected by the slave, mark the position of the point collected at the moment of the received synchronization mark, become the synchronization point, and send it along with the data packet where the point is located To the signal collection component 110. Since the sampling accuracy of each signal source is independent of each other, the number of signals collected in the same objective time interval is not equal. For example, master A, slave B, and slave C, the clock precision of master A and slave B is consistent. The sampling rate of slave A is 250Hz, and 250 data points are collected in 1 second. Compared with the master A, the clock accuracy of slave B is -0.4%, that is, 249 data points are collected in 1 second. If the clock marks of the master and the slave are not synchronized, the problems of the data received by the master are as follows: 1. Because of the accumulated error, the starting point of each data packet of the slaves B and C is actually inconsistent, and the longer the running time, the difference 2. The length of slave data received by the master per unit time is inconsistent. Regarding the above situation, returning to FIG. 2 , the signal synchronization processing unit 40 performs synchronization processing on the received signals from multiple signal sources.

First, the synchronization processing unit 40 extracts a synchronization mark from the data sent back from the slaves B and C collected by the signal collection component 110, and aligns the data headers of B and C with the synchronization mark as a starting point. Specifically, the received waveforms are aligned according to the corresponding synchronization marks, so as to achieve the purpose of waveform synchronization.

Subsequently, the synchronization processing unit 40 performs stretching or squeezing processing on the signals with different sample data quantities. Specifically, if there are still multiple points in the difference between the synchronized waveforms (caused by small errors in the time pulses of different devices), the stretching or squeezing algorithm is used to process the waveforms so that the processed waveforms can be aligned. For example, a linear interpolation process is performed on the signal of slave C which should collect 250 data points but only collects 249 data points, so that it is stretched to 250 data points.

Likewise, if the sampling rate of slave C has many data points, for example, 251, squeeze processing is required. The synchronous processing unit 40 obtains the data C' with the same length as the slave B through squeeze calculation, and sends B[250] and C'[250] into subsequent calculation for required processing. It should be pointed out that interpolation can use various mathematical interpolation methods according to the actual signal characteristics, and here only the simplest linear interpolation is used as an example to illustrate. The same extrusion can adopt other extrusion methods. The disclosure can not only correct the influence caused by the clock error of each component of the system, but also solve the problem of inconsistent sampling rates used by different slave machines.

It should be pointed out that the chip 24L01 is used in all units involved in signal acquisition and transmission. nRF24L01 is a single-chip wireless transceiver chip produced by NORDIC that works in the ISM frequency band of 2.4GHz to 2.5GHz. The wireless transceiver includes: a frequency generator, an enhanced "ShockBurst" mode controller, a power amplifier, a crystal oscillator, a modulator and a demodulator, and its output power channel selection and protocol settings can be set through the SPI interface. It can be connected to almost all kinds of single-chip microcomputer chips and complete wireless data transmission. Although the 24L01 chip is used as an example for illustration here, other chips with the same function may also be used, and no examples are given here.

The synchronization mark generated and sent by the timing information sending unit 10 is sometimes called a beat signal, a time stamp, a time header, a second synchronization header or a synchronization mark. A signal transmitted by the timing information sending unit 10 through a radio frequency of 2.4 GHz may also be used to send the synchronization signal through other wireless channels, as long as the purpose of the present disclosure can be met. The synchronization mark is sent once every T cycle for one second, and the data is only one byte. Synchronization mark can be the synchronous frame of a fixed data, also can be the synchronous frame that contains number, also can be the absolute time that the timing information transmission unit 10 itself runs, and it comprises the current time of year, month, day, hour, minute, second and microsecond, such as December 2016 March 26 at 22:35:10:50 ms. Optionally, the synchronization frame may also include the frame number and the current absolute time at the same time. When the synchronization frame is sent and received in the system, there is usually a small transmission delay, which is negligible for the technical solution of the present disclosure. However, it should be pointed out that when the synchronization frame is loaded, the delay can be calculated so as to accurately load the synchronization frame, that is, the transmission delay is deducted from the slave signal source. Since the calculation of the data transmission delay belongs to the prior art, it will not be described here.

After the master signal source or the slave signal source obtains the synchronization mark, the acquisition signal is to mark the position of the point collected at the moment of the received synchronization mark and become the synchronization point, thereby encoding or loading the synchronization signal into the collected signal or in a packet. Since the clock precision of each device is different, it may result in the situation that the number of sampling points is insufficient or excessive within a range of a synchronization mark. The number of the synchronization mark can be used repeatedly in a certain cycle. As mentioned above, after receiving the synchronization mark, the slave signal source loads the synchronization mark into the collected signal or data packet within the same synchronization cycle T. Since the slave data packets are mixed with synchronization marks, when the slave signal sources send signals to the signal collection component 110, they may be sent out of sequence, and the signal synchronization processing can also sort and align data packets of different signal sources based on the synchronization 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 host signal source A finishes receiving the data from the slave machine in a complete cycle, it then performs data stretching or squeezing processing, and the system responds longer (it takes at least one full cycle to obtain the 250 and 249 values of the slave machines B and C in the above example. value), and at the same time, due to the reprocessing of the slave data received for a complete cycle, a large amount of storage space is taken up. Therefore, how to continuously process data in small batches can help eliminate the need for large storage space and shorten system response time. For this reason, the system of the present disclosure also provides a cycle updating unit 50 . After the system works for a period of time based on the initial synchronization period T1, based on the data collected by each slave signal source B or C, the error of different slave signal sources is obtained. For example, the slave signal source C should collect 250 data points and only 249 data points were collected. Therefore, its error is determined and unchanged within a predetermined time. For this reason, the period update unit 50 can 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 process the sampling data received in the synchronization period T2. Stretching and squashing of signal data. Usually T2 is half of T1. Optionally, T1 is an integer power multiple of 2 of T2. Thus, using the previously measured error value, the data of the slave signal source C is processed on a first-come-first-served basis. Specifically, if T1=2T2, within the entire period of T1, the same synchronization mark can be repeatedly sent twice, so that there is no need to wait for all the data of a complete period T1. Because in a general system, the error of the system clock under fixed environmental conditions is basically constant (unless the drastic temperature change will cause the clock to drift; if a high-stability clock is used, such as a temperature-compensated crystal oscillator, there will be no drift problem at all). Obtaining part of the data in a complete T1 cycle in this way can reduce the data storage space of the signal collection component 110 or the signal synchronization processing unit 40 by T2/T1, and reduce the time required for calculation to T2/T1, Cache occupancy is reduced by T2/T1. In addition, when the environment changes and the system finds that the clock of the slave is drifting, the master can configure the intermittent synchronization period T at any time or at regular intervals to correct the error.

FIG. 6 is a block diagram of family ward units managed by the family ward unit management system according to the present disclosure. The control assembly 120 takes STM32F407 as the core control unit, and uses a 16-bit CPU bus to connect with the liquid crystal display unit 105 (for example, a 2.4-inch LCD screen. The liquid crystal display unit 105 can display ECG waveform, blood oxygen pulse wave waveform, heart rate, blood oxygen Saturation, blood pressure measurement value, body temperature, home ward unit battery power, family ward unit WIFI and Bluetooth disconnection and connection status, etc. The blood pressure detection unit 160 (FPGA) is connected to the CPU of the control component 120 using an 8-bit I/O bus The continuous blood pressure is calculated by using the ECG waveform input by the electrocardiographic clothing 140 and the blood oxygen waveform data input by the blood oxygen detector 150 .

When the key control unit 110 of the control component 120 is pressed, the CPU scans the low level state of the I/O port to determine that the key is pressed. The Bluetooth unit 515 adopts the Bluetooth 4.0 communication protocol, and interacts with the CPU of the control component 120 through the serial port. The WIFI unit 510 adopts 2.4GHz, IEEE802.11 wireless LAN communication protocol, and interacts with the control component 120CPU through the serial port. The blood oxygen detector 150 receives the signal measured by the blood oxygen probe 151 to measure the pulse wave and blood oxygen saturation, and interacts with the CPU of the control component 120 through the serial port. The ECG suit 140 acquires the ECG signal of the user. The amplified analog ECG signal is sent to the analog-digital sampling port of the CPU of the control unit 120 , thereby collecting ECG waveforms and displaying the collected ECG waveforms on the display unit 105 .

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

The electrocardiographic suit 140 of the present disclosure also includes a body temperature unit. The body temperature unit can be an electronic thermometer, which uses a thermistor to sense the surface temperature of the human body, amplifies and collects the variation of the resistance of the thermistor through an operational amplifier, and calculates the body temperature. The body temperature unit sends the detected body temperature to the CPU of the control component 120 through the bluetooth chip and the bluetooth unit in the signal collection box of the electrocardiograph 14 through the bluetooth 4.0 protocol, and displays it to the user on the display unit 105 . The family ward unit of the present disclosure also includes a temperature and humidity module, which 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 family ward unit managed by the family ward unit management system of the present disclosure uses the Korotkoff sound principle to measure human blood pressure, and interacts with the CPU through a serial port. In addition, the family ward unit of the present disclosure also includes a temperature and humidity unit (not shown), which can measure the temperature and humidity of the environment, and interact with the CPU through the HDQ protocol. It should be noted that, when performing blood pressure detection, the blood pressure detection unit 160 usually performs blood pressure calibration. When the family ward unit management system is used for the first time, the mobile client will prompt the user to perform cuff blood pressure calibration. For blood pressure calibration, a blood pressure calibration command is first issued through the mobile phone client, and the family ward unit management system performs the approval operation after receiving the calibration command. If the current time is more than 7 days from the last blood pressure calibration (can also be set to 3 days, 5 days or 14 days), the family ward unit management system will prompt "Blood pressure needs to be calibrated" after starting. It is usually used for continuous blood pressure calibration by collecting the blood pressure parameters of the human arm cuff. After the calibration is successful, the family ward unit sends a success status to the mobile client. The mobile client and the family ward unit record the calibration time and results at the same time, and remind the user to perform calibration again after 7 days. Calibrating blood pressure is to calibrate continuous blood pressure. Optionally, the client can be integrated into the control component 120 and displayed on the display unit. Therefore, in the absence of a mobile phone client, blood pressure calibration can also be performed automatically, prompting the user to perform calibration and automatically completing the calibration operation.

The above-mentioned family ward unit is a device that comprehensively measures various vital sign parameters of the human body, such as blood oxygen measurement, heart rate monitoring, blood pressure trend monitoring, ECG monitoring, body temperature monitoring, health index BMI monitoring, and body fat monitoring. The user's vital sign data can be automatically uploaded to the cloud server through a dedicated mobile communication client through WiFi, and stored for a long time. For the data that has been uploaded, the user can pay to consult the doctor about the user's health status through the cloud service. According to the present disclosure, the household family ward unit can support the use of multiple persons in the family, can record abnormal sign data in time, and facilitates medical treatment. According to the client of the home family ward unit of the present disclosure, intelligent data analysis and data cloud storage can be performed.

The clients are usually various mobile phone client APPs or PC client APPs. In related technologies, the user remotely controls the smart terminal device through the client APP installed on the user unit, and can use Bluetooth, iBeacon, Near Field Communication (Near Field Communication, NFC), non-contact radio frequency identification (Radio Frequency Identification, RFID) and other radio frequency technology.

For this one-to-one situation of monitoring device and home ward unit, as mentioned earlier, when the smart monitoring device is shared by several people, it will cause all data of the monitoring device to be transmitted to the client of the admin user's home ward unit Therefore, all users who share the monitoring device will not know which data in the data obtained by the monitoring device belong to their own data, and cannot obtain their own accurate historical data. With the development of society, people pay more and more attention to their own health, so they pay more attention to their various physical indicators. Therefore, people will prepare one or more monitoring devices or monitoring equipment at home, so as to check or monitor their various physiological indicators frequently, so as to guide their daily life behavior based on the daily detection or monitoring results. For a family, it is obviously a waste to equip each member with the same monitoring device. Therefore, if an account is configured for each family member or each member of a certain group under the same monitoring device, This will bring great convenience to all members. For this reason, in order for multiple users to share the monitoring device in each family ward unit, the family ward unit management system according to the present disclosure can provide each family ward unit owner with a sub-user account for each monitoring device.

Returning to FIG. 1 , the family ward units 01 , 02 , 03 . . . N managed by the family ward unit management system according to the present disclosure can be connected to the cloud server of the supplier of the monitoring device through the Internet. The Internet can be replaced by a communication network, or it can be a mobile Internet. The provider cloud server can be any other web server. As mentioned above, the monitoring device can be any intelligent monitoring device, such as blood pressure monitor, blood glucose meter, fetal heart rate detector, body temperature detector, body weight and body fat detector, blood oxygen detector, ECG detector, urine detector, body index Detectors and other monitoring devices capable of detecting physiological parameters of the human body. The monitoring device can be provided with a built-in wireless communication unit, which can perform data transmission and information interaction with other equipment through Bluetooth, Wifi, GPRS and 3G/4G communication forms, and can also perform data transmission and information interaction with other equipment through wired communication. . The monitoring device may be an electrocardiogram instrument and a blood pressure monitor. Generally speaking, before or after purchasing the monitoring device, the user of the family ward unit registers an administrator user account by logging into the login registration application client provided by the monitoring device supplier. Then, by binding the unique serial number (SN) of the purchased monitoring device with the administrator user account, all kinds of data generated by the monitoring device are recorded under the account of the logged-in user. A user under an administrator user account may, upon logging into the client, register one or more sub-user accounts affiliated with the administrator user account based on the identification numbers (IDs) of other users' family ward units. The sub-user account can log in through the client, and when the monitoring device is connected to the family ward unit of the sub-user account, receive data from the monitoring device and record the data under the corresponding sub-user account. At the same time, the data of the sub-user account can also be transmitted to the cloud server through the Internet for storage.

A family unit can contain an administrator user account and multiple sub-user accounts. The users of the administrator user account and the sub-user account all log in and use the monitoring device through the family ward unit, and directly store the data locally in the monitoring device or transmit it to the cloud server.

Internet access is established by turning on the client side of the family ward unit. If the user does not have an account, he can enter the administrator user registration page and perform the administrator user registration process. If the user has an account, he can select the default login administrator user page to log in to the administrator user account, or he can select the sub-user account registration login status to register a sub-user account. The administrator user account can manage all the data of the administrator user's own account and the sub-user accounts to which it belongs. In addition, after the user logs into the sub-user account, he can also manage the data of the sub-user account.

The registration process of the administrator user account is carried out in a conventional registration method, and the above-mentioned user identity information includes but is not limited to one or more of mobile phone number, E-mail, and ID number. The registration is completed by the registration agency, such as the monitoring device management system, sending a verification code to the user's mobile phone to verify the uniqueness of the user ID. If the server registration agency determines that the user registration does not exist in the data table, after the user enters the user ID, password and verification code in the registration window, submit the above registration information to the server registration agency for processing until the registration is successful. After the registration is completed, enter the account management page of the administrator user, and in the management page, the administrator user can manage the sub-user account and the bound monitoring device under the account through the management page.

During the above login and registration process, the family ward unit performs user identity authentication, user password and information modification, uses the user's unique ID as the user's unique identification standard and corresponds to the background server device. After the user logs into the client of the family ward unit, the family ward unit and the monitoring device through its communication unit will automatically identify and connect with the monitoring device according to the binding performed by the user before, and perform initialization settings and storage.

Usually, a one-to-one approach is adopted for the use of monitoring devices by users, and one monitoring device is intelligently used by one user. This is to prevent data ownership confusion. Therefore, in order to enable a monitoring device to be shared among multiple users within a small group (for example, within a family), a sharing mechanism may be provided. First, as described above, if the administrator user account exists, the login and registration operations of the sub-user account are performed on the registration and login page of the non-administrator user account. Enter the identity information of the sub-account (for example, user communication identification, such as SIM card number) and password, and then click the register button. The multi-user management component in the registration server (which may be the same server as the monitoring device provider server) obtains one or more user communication identifications input by the administrator user through the family ward unit, and sends the one or more user communication identifications to the one or more user through the communication network. The communication device to which the user communication ID belongs sends a verification code. Enter the verification code in the administrator user page and send it to the registration server. It should be pointed out here that the administrator user can directly obtain the verification code received from the family ward unit identified by the one or more user communications, or the registration server can simultaneously send the verification code of the sub-account that needs to be registered to the admin user's home ward unit. The multi-user management component verifies the obtained verification code, so as to generate one or more sub-user accounts belonging to the administrator user account, thereby establishing a sub-account under the administrator user account, and automatically binding the sub-accounts to the Under the administrator user account, at the same time, all information of the sub-user account is transmitted to the monitoring device provider server through the administrator user account. Alternatively, it is also possible to form multiple sub-user accounts under the administrator user account directly at the family ward unit without an authentication step. That is, the registration of the sub-user account takes place locally at the admin user's home ward unit. Especially when a monitoring device system is set up in a family ward unit, if the administrator user has logged in, the registration process of the sub-user account may not need to go through the verification process, and multiple sub-user account usernames are directly generated under the administrator user account and assigned password.

Subsequently, it is determined whether the administrator user needs to bind the monitoring device to the sub-user account. If it is necessary to bind the monitoring device for the sub-user account through the selection of the administrator user, the client will display the serial numbers (SN) of all the monitoring devices bound to the administrator user account. Afterwards, the administrator user selects the corresponding serial number from the serial numbers of all monitoring devices under the administrator user account, and the first binding component imports the serial number of the selected monitoring device into the sub-user account based on the selection of the administrator user In the parameter table, the terminal device with the selected serial number is bound to the sub-user account.

Admin users can add monitoring devices in the client of the family ward unit. The communication module in the family ward unit detects whether there is a new smart monitoring device in its detection range through Bluetooth, Wifi, GPRS and 3G/4G communication forms (smart monitoring devices with different serial numbers from the existing monitoring devices under the administrator user account) device). If there is a new smart monitoring device (ie a new serial number), the acquired 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. new serial number) (for example, the newly purchased smart monitoring device is not turned on), the client of the family ward unit will pop up the monitoring device serial number input field, so that the administrator user can The serial number of the newly purchased smart monitoring device is input into the input 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 the serial number of one or more monitoring devices from the family ward unit (ie, the identification of the monitoring device), and compares it with the serial number of the bound monitoring device to verify one or more Whether the identification of the monitoring device has been bound. Finally, the second binding component 16 binds the identification of the unbound monitoring device to the administrator user account. In this way, an admin user can bind multiple monitoring devices under his admin user account.

In some embodiments, after the monitoring device is bound to the administrator user account and several sub-accounts, when the account is in use, the specific login window and registration window can be set as the administrator user account login by default, or as sub-accounts. Account login is not limited in this embodiment of the present disclosure. However, when the user is a user of a sub-account, in addition to inputting the user name, password and verification code of the sub-account, the user also needs to input an administrator user account, so that the sub-account can log in successfully.

When the administrator user logs in, the administrator user can manage the sub-user accounts under his account, such as adding or deleting sub-user accounts and binding the sub-user accounts to a certain monitoring device. Check the status of sub-user accounts under the administrator user account. Sub-user accounts can be added when there are no sub-user accounts.

The above specifically describes a family ward unit management system according to the present disclosure. As mentioned above, when users configure parameters for the monitoring device, they can create different users for each bound device; each user has different parameters corresponding to different devices, so a user’s home ward unit stores a Configuration parameter table. The parameter table can also be stored in the cloud server. These parameters are, for example: device serial number, user account number, user profile (such as height, weight, gender, age) and the like. The administrator user sets a mobile phone number and password for each user through registration, so that users can log in and query their own data. Admin users can manage all devices and manage all user information, and each non-administrator user can query their own real-time data on the monitoring device (such as pulse rate, heart rate, blood oxygen saturation, systolic blood pressure, diastolic blood pressure, body movement range, pressure value) and historical data and configure its own parameters in the device.
