Referring first to fig. 1, fig. 1 is a schematic diagram of an implementation environment provided in this embodiment, where the implementation environment is only one possible environment of the technical solution of this embodiment, and is not limited to specific hardware structures and numbers.
In this embodiment, the medical telemetry system includes a telemetry terminal 100, a plurality of available repeaters, a receiver 300, and a central monitoring station 400.
The number of available repeaters may be plural, as shown in fig. 1, and the medical telemetry system uses 3 available repeaters as an example, including the first repeater 210, the second repeater 220 and the third repeater 230, and the number of available repeaters may be increased or decreased according to actual requirements.
It should be noted that, the plurality of available repeaters may be respectively connected to the receiver 300 in a communication manner, or may perform signal transfer in a cascade manner, for example, as shown in fig. 1, the first repeater 210 is connected to the second repeater 220, the second repeater 220 is connected to the third repeater 230, the third repeater 230 is connected to the receiver 300, the data of the first repeater 210 is sequentially sent to the receiver 300 through the second repeater 220 and the third repeater 230, and so on, the receiver 300 may distinguish the repeaters for sending the data according to the device identifier carried in the data.
Wherein, the telemetry terminal 100 may communicate with available repeaters through a wireless network, for example, as shown in fig. 1, the telemetry terminal 100 transmits a broadcast signal to a target channel through the wireless network, and when the first repeater 210, the second repeater 220 and the third repeater 230 are both within a signal receiving range, the broadcast signal may be received at the same time; when the first repeater 210 and the second repeater 220 are within the reception range and the third repeater 230 is not within the reception range, the first repeater 210 and the second repeater 220 acquire the broadcast signal and the third repeater 230 does not acquire the broadcast signal.
The receiver 300 may be communicatively connected to the central monitoring station 400 via a wireless network or may be communicatively connected via a wired network, which is not limited herein.
The communication method according to the embodiment of the present invention will be further described based on the implementation environment shown in fig. 1.
Referring to fig. 2, fig. 2 is a flowchart of a communication method of a medical telemetry system according to an embodiment of the present invention, where the communication method of the medical telemetry system includes, but is not limited to, steps S10 to S60.
S10, a telemetry terminal determines a binding relay from available relays through signal search, and after the telemetry terminal establishes communication connection with the binding relay, the binding relay generates binding information and reports the binding information to a receiver;
S20, broadcasting a broadcast signal carrying physiological data when the telemetry terminal collects the physiological data;
s30, when the binding relay and the unbinding relay acquire broadcast signals, the binding relay sends a first data packet to the receiver based on the detected binding information, the unbinding relay sends a second data packet to the receiver based on the unbinding information, wherein the first data packet carries physiological data and a first quality parameter value, the first quality parameter value is used for indicating the signal quality of the broadcast signals received by the binding relay, the unbinding relay is an available relay without binding information, the second data packet carries a second quality parameter value, the second quality parameter value is used for indicating the signal quality of the broadcast signals received by the unbinding relay, and the number of the unbinding relays is at least one;
s40, the receiver sends physiological data carried by the first data packet to the central monitoring station based on the binding information;
s50, when the receiver detects that the first quality parameter value is inferior to a preset first threshold value, determining a target relay from unbound relays, wherein a second quality parameter value of the target relay is superior to the first threshold value;
S60, the receiver determines new binding information based on the target relay, deletes the binding information in the binding relay, and issues the new binding information to the target relay so that the target relay responds to the new broadcast signal based on the new binding information.
In step S10, the telemetry terminal determines the binding relay by means of signal search during initial use, so that initial access of the telemetry terminal can be achieved, after the binding relay is determined, the telemetry terminal only needs to perform connection establishment with the binding relay, after connection establishment is completed, the binding relay determines a binding relationship and generates binding information, and the binding information is reported to the receiver for maintenance. The binding information in this embodiment is used to indicate the available repeater with the best communication quality between the telemetry terminal and the current available repeater, but the repeater that is in communication with the telemetry terminal only is not bound, the connection between the telemetry terminal and the binding repeater is established to determine that the telemetry terminal is connected to the medical telemetry system, and the switching of the repeater is completed by updating the binding information between the receiver and the available repeater, and does not involve disconnection of the telemetry terminal from the binding repeater and establishment of a connection with another available repeater.
In step S20, the telemetry terminal performs transmission of physiological data in a broadcast manner, instead of performing point-to-point data interaction with the binding relay, based on the characteristics of broadcast communication, all binding relays and unbound relays within the receiving range of the broadcast signal can acquire the broadcast signal, so that update interaction of the binding information does not affect the receiving of the broadcast signal, but the relay determines the content of the data packet reported to the receiver based on whether the binding information is provided or not, and therefore, by adopting the technical scheme of the embodiment, continuity and integrity of uploading of the physiological data can be effectively ensured, data loss caused by switching of the relay is effectively avoided, and reliability of the medical telemetry system is improved.
In step S30, since the telemetry terminal is used as the transmitting end of the broadcast signal and cannot adjust the received content of the receiving end, in this embodiment, the binding information is used as the information base of each repeater for determining the response broadcast signal, and the binding repeater generates the binding information and reports the binding information to the receiver for maintenance when the binding repeater establishes a connection in step S10, so that the binding repeater has the binding information in the initial stage, and after the binding repeater acquires the broadcast signal, because the binding information is detected, after the physiological data is acquired from the broadcast signal, a first data packet is generated according to the physiological data and the first quality parameter value, and the first data packet is transmitted to the receiver, so that the receiver can acquire the physiological data.
It should be noted that, since the medical telemetry system is applied to a scene with a wide range of environments such as a hospital, even if the telemetry terminal transmits data in a broadcast manner, not all available repeaters are within the signal receiving range, and therefore, the unbound repeater in this embodiment is an available repeater capable of receiving broadcast signals in addition to the bound repeater. Based on the above description, the unbound repeater does not have binding information, and can obtain physiological data after acquiring the broadcast signal, but the physiological data is reported to the receiver by the bound repeater, so that the unbound repeater does not need to repeatedly send the physiological data, but generates a second data packet according to the second quality parameter value and sends the second data packet to the receiver, thereby effectively saving network bandwidth and reducing unnecessary data transmission.
It should be noted that, in this embodiment, the first quality parameter value and the second quality parameter value may be the same parameter type, and the difference is only that the transmitted object is a bound relay or an unbound relay, and the receiver can monitor the signal quality received by each relay in real time through reporting the first quality parameter value and the second quality parameter value, so as to provide a signal basis for switching the relay. The first quality parameter value and the second quality parameter value may be parameters capable of representing the quality of the received broadcast signal, such as signal strength, signal-to-noise ratio, packet loss rate, and the like, and are not limited to specific parameter types. Since the parameter types of the first quality parameter value and the second quality parameter value are the same, the first threshold value can be set to determine the advantages and disadvantages of the present embodiment are not simply equal to being greater than or less than, and are determined according to the parameter type, for example, the signal strength is adopted by the parameter type, the greater the quality parameter value represents the better, and the smaller the quality parameter value represents the better if the packet loss rate is adopted, and the detailed description is omitted.
It should be noted that, in step S40, the receiver may simultaneously receive the first data packet of the binding relay and the second data packet of the unbinding relay, so that, in order to determine the type of the data packet, the first data packet may be determined from the received data packets based on the binding information, for example, the binding information is used to know that the relay 1 is the binding relay, and after the data packet sent by the relay 1 is acquired, the first data packet is determined, and the processing data is parsed therefrom and sent to the central monitoring station.
It should be noted that, although the communication quality of the binding repeater may be optimal at the time of initial connection, the communication quality between the telemetry device and each repeater is dynamically changed when the patient moves or is affected by other external factors (other persons, medical devices, walls, etc.). In step S30, the binding repeater transmits a first quality parameter value via the first data packet, the unbinding repeater transmits a second quality parameter value via the second data packet, and both the first quality parameter value and the second quality parameter value are determined based on the same broadcast signal, so that the receiver can determine the quality of communication between the telemetry device and each repeater based on the quality parameter values. If the available repeater with the optimal communication quality is used as the binding repeater, the repeater switching frequently occurs, the network resource is wasted, and the stability of the medical telemetry system is also affected, so in the embodiment, after the binding repeater is determined, in step S50, the first threshold is set as the basis for whether the binding can be maintained, that is, when the first quality parameter value is better than or equal to the first threshold, the communication quality between the binding repeater and the telemetry device can be considered to be capable of normally performing communication of physiological data, at this time, even if the second quality parameter value of another unbound repeater is better than the first quality parameter value, the repeater switching is not performed, and when the first quality parameter value of the binding repeater is worse than the first threshold, the communication quality between the telemetry terminal and the binding repeater is harder to maintain transmission of physiological data, and the switching of the repeater is required, and when the seat target repeater with the second quality parameter value determined from the unbound repeaters is better than the first threshold is switched, the communication capable of continuously maintaining physiological data after the switching is ensured. The specific value of the first threshold may be adjusted according to actual requirements, which is not limited herein. When the second quality parameter value of each unbound repeater is better than the first threshold value, the value can be selected as the target repeater with the optimal value, or the nearest target repeater can be selected, and the method is not limited in this way.
It should be noted that, in step S60, based on the description of the above embodiment, the present embodiment decouples the switching of the repeater from the broadcasting of the telemetry device, that is, the switching of the repeater is achieved by the replacement of the binding information, the switching process and the broadcasting of the telemetry device are independent processes, after determining the target repeater, the receiver sends the binding information to the target repeater, and deletes the binding information in the previous binding, as shown in fig. 4, the repeater 2 is the initial binding repeater, after determining the target repeater is the repeater 3, the binding information is added to the repeater 3, and the binding information is deleted from the repeater 2. After the updating, when the telemetry device broadcasts the broadcast signal again, the repeater 2 does not detect the binding information any more, and sends out the second data packet according to the processing mode of the unbound repeater, and the repeater 3 sends out the first data packet according to the processing mode of the bound repeater due to the detection of the binding information, thereby realizing the noninductive switching of the repeater.
According to the technical scheme of the embodiment, after the telemetry terminal is connected with the binding repeater, the binding repeater reports the binding information to the receiver for maintenance, so that the initial binding of the repeater and the network access of the telemetry terminal are realized; the remote measuring terminal sends collected physiological data through broadcast signals in the operation process, each repeater determines the content of a data packet based on whether the data packet has binding information, a first data packet sent by the binding repeater with the binding information comprises the physiological data and a first quality parameter value, a second data packet sent by the unbound repeater comprises a second quality parameter value, and a receiver acquires the physiological parameter from the first data packet and then forwards the physiological parameter to a central monitoring station, so that the reporting of the physiological data is realized; meanwhile, the receiver monitors the signal quality of broadcast signals received by all the repeaters in real time based on the quality parameter values, when the receiver determines that the first quality parameter value of the binding repeater is inferior to a first threshold value, the switching process of the repeater is triggered, a target repeater is determined from unbound repeaters based on the second quality parameter value, binding information is updated in the receiver and then sent to the target repeater, binding information of the previous binding repeater is removed, connection disconnection and establishment of telemetry equipment are not involved in the switching process, non-inductive switching of the repeaters is achieved, a telemetry terminal can maintain data broadcasting, continuity and integrity of physiological data are effectively ensured, and reliability of a medical telemetry system is improved.
In addition, in an embodiment, referring to fig. 3, step S10 further includes, but is not limited to, the following steps:
s11, after the telemetry terminal is started, determining the running state of the equipment through equipment self-checking;
s12, when the equipment running state represents that the telemetry terminal runs normally, determining the signal strength between the telemetry terminal and each available repeater through signal searching;
and S13, the telemetry terminal determines the available repeater with the strongest signal strength as the binding repeater.
After the telemetry terminal is started, the running state of the device can be determined through device self-checking, for example, whether the device is correctly worn, whether the sensor can acquire physiological data, whether the battery state is normal, and the like.
It should be noted that, when the telemetry terminal operates normally, the signal strength between the telemetry terminal and each repeater can be determined through signal searching, and a specific method of signal searching is a technology well known to those skilled in the art, and will not be described herein.
It should be noted that, since the telemetry device is worn on the patient, and the patient moves at a slower rate, the signal quality between the telemetry device and each available repeater is changed slowly, and after the signal strength of each available repeater is determined by signal search, the signal strength can be used as a binding repeater in the forefront, so that switching of the repeater can be reduced, the stability of the system can be improved, and the risk of losing physiological data can be reduced by using a higher signal strength, and the stability of the data can be improved.
In addition, in an embodiment, referring to fig. 3, step S50 further includes, but is not limited to, the following steps:
s51, the receiver determines unbound repeaters with the second quality parameter values being better than the first threshold as candidate repeaters;
s52, the receiver determines the candidate relay with the second quality parameter value being superior to the second threshold as the switchable relay, wherein the signal quality indicated by the second threshold is superior to the first threshold;
and S53, the receiver determines a target relay from the switchable relays based on the principle that the second quality parameter value is optimal.
It should be noted that, according to the description of the embodiment shown in fig. 2, the first threshold is used as a trigger condition for switching a relay, when the first quality parameter value of the bound relay is inferior to the first threshold, the switching is triggered, and the number of unbound relays may be plural, because the switching of the relay is aimed at switching to the relay with better communication quality, the receiver determines the unbound relay with the second quality parameter value superior to the first threshold as a candidate relay based on the first threshold, so as to avoid switching to another relay with poorer communication quality. When the second quality parameter value is not better than the first threshold value, the communication quality between all the available repeaters and the telemetry terminal is poor, and it is likely that the telemetry terminal leaves the coverage area of all the available repeaters, and no good communication effect can be achieved in any case of handover, so that the communication effect is not in the range of the discussion of the embodiment, and the subsequent description is not repeated.
It should be noted that, after determining the candidate repeater, although the second quality parameter value of the candidate repeater is better than the first threshold, the comparison of the values is simply a magnitude relation, and it is likely that the first quality parameter value is slightly worse than the first threshold, the second quality parameter value is slightly better than the first threshold, and the difference between the first quality parameter value and the second quality parameter value is small, so that even if the repeater is switched, the communication effect is not significantly improved. Based on this, the receiver further screens the candidate relay by the second threshold, and the embodiment determines the candidate relay with the second quality parameter value being better than the second threshold as the switchable relay, and when the value difference between the second threshold and the first threshold is satisfied and the second quality parameter value is better than the second threshold, it can be considered that there is a more obvious difference between the quality of the broadcast signal received by the switchable relay and the binding relay, and the transceiving effect of the physiological data can be improved after switching. The signal quality indicated by the second threshold is better than the first threshold, e.g. the signal quality employs signal strength, the second threshold is greater than the first threshold, and e.g. the signal quality employs packet loss rate, the second threshold is less than the first threshold.
Illustratively, referring to fig. 4, in this example, the types of quality parameters are exemplified by signal strength, and the available repeaters include repeater 1, repeater 2, and repeater 3, with repeater 2 as the initial binding repeater, the first threshold being TH1, the second threshold being TH2, the signal strength of repeater 1 being a, the signal strength of repeater 2 being B, and the signal strength of repeater 3 being C, where a < C is exemplified.
When the receiver determines that the binding relay is the relay 2 according to the binding information, the data packet sent by the relay 2 is determined to be a first data packet, the signal intensity B is obtained from the first data packet, and when the detection that B < TH1 triggers the relay switching flow, the signal intensity A and the signal intensity C are obtained from a second data packet sent by the relay 1 and the relay 3.
For example, when a > TH1, C > TH1, repeater 1 and repeater 3 are determined as candidate repeaters, if a < TH2, C > TH2, repeater 3 is determined as a switchable repeater, and since there is only one switchable repeater, repeater 3 is determined as a target repeater; if A < TH2 and C < TH2, the repeater switching is not performed; if a > TH2, C > TH2, repeater 1 and repeater 3 are determined to be switchable repeaters, and repeater 3 is determined to be a target repeater due to a < C. After the target relay is determined, deleting the binding information in the relay 2, and deploying the binding information in the relay 3 to complete relay switching.
For another example, when a < TH1, C > TH1, the relay 3 is determined as a candidate relay, and if C < TH2, no handover is performed, and the current binding relationship is maintained. If C > TH2, determining the repeater 3 as a switchable repeater, determining the repeater 3 as a target repeater because there is only one switchable repeater, deleting the binding information in the repeater 2, and disposing the binding information in the repeater 3 to complete the repeater switching.
In addition, in an embodiment, referring to fig. 3, step S20 further includes, but is not limited to, the following steps:
s21, the telemetry terminal generates a broadcast signal based on physiological data;
and S22, broadcasting the broadcast signal to a target channel, wherein the target channel is a pre-configured broadcast channel between the telemetry terminal and the available repeater.
It should be noted that, after the telemetry terminal establishes a connection with the binding repeater, it is determined that the telemetry terminal may access the medical telemetry system, and based on the description of the above embodiment, the telemetry terminal in this embodiment does not send physiological data to the binding repeater point-to-point, but sends a broadcast signal to the target channel, so that the binding repeater and a plurality of unbound repeaters can obtain the broadcast signal, thereby implementing operations such as repeater communication quality monitoring, repeater switching, and the like in the above embodiment.
It should be noted that, in this embodiment, the telemetry terminals may collect physiological data through a preset period, and configure a broadcast channel as a target channel before use, and the target channel of each telemetry terminal may be occupied only.
In addition, in an embodiment, referring to fig. 3, step S30 further includes, but is not limited to, the following steps:
s31, when the binding repeater acquires a broadcast signal from a target channel and successfully detects binding information, determining a first quality parameter value and a target sequence number, wherein the target sequence number is the data sequence number of the current physiological data, and the data sequence number is used for indicating the accumulated acquisition sequence of the physiological data and is carried in the physiological data, and the data sequence numbers of adjacent acquisition periods are mutually continuous;
s32, the binding repeater generates a first data packet based on the target sequence number, the physiological data, the first quality parameter value and the first relay identifier, wherein the first relay identifier is the equipment identifier of the binding repeater;
S33, when the unbound repeater acquires a broadcast signal from a target channel and fails to detect binding information, determining a second quality parameter value and a target sequence number based on the broadcast signal, and generating a second data packet based on the second quality parameter value and a second relay identifier, wherein the second relay identifier is a device identifier of the unbound repeater;
s34, the unbound relay and the bound relay both buffer the target sequence number and the corresponding physiological data, and release the buffer after a preset buffer time.
The method for determining the reception quality based on the broadcast signal is well known to those skilled in the art, and the specific determination method of the first quality parameter value and the second quality parameter value is not limited herein, and the parameter types of the first quality parameter value and the second quality parameter value may be the same.
It should be noted that, when broadcasting physiological data, the telemetry terminal can determine a data sequence number according to the acquisition sequence of the physiological data, and carry the data sequence number in the physiological data transmitted each time, so as to provide a basis for verifying the continuity and the integrity of the data.
It is noted that the data sequence number of the physiological data broadcasted each time is continuous, and the broadcast signal can be acquired by the binding relay and the unbinding relay, so that the relay can buffer the target sequence number and the physiological data acquired each time, and the data buffer provides a basis for the supplementary data when the verification of the data continuity and the integrity is not passed. Meanwhile, in order to avoid excessive memory occupation, a certain buffer duration can be set, and the buffer duration is released after each group of target serial numbers and physiological data buffer reach the buffer duration, for example, the buffer duration can be an integer multiple of an acquisition period, after the receiver acquires physiological data of a plurality of acquisition periods, the probability that physiological data before the acquisition periods is used for data complement is smaller, and memory saving space can be released.
It should be noted that, in this embodiment, the buffering of the physiological data and the target sequence number is performed by the binding relay and the unbinding relay at the same time, and according to the description of the above embodiment, the receiver acquires the physiological data from the first data packet sent by the binding relay, and in the actual use process, the data sent by the binding relay may be wrong, if the signal quality of the binding relay is poor, the data is acquired from the binding relay for the second time, and the error is likely to be continued, so the complement data can be acquired from the buffer of the unbinding relay when the data integrity verification is performed, and the miss data can be acquired from any relay when the data continuity verification is performed, so as to ensure the efficiency and reliability of the data complement.
It should be noted that, referring to fig. 5, each relay may be cascaded, and the data packets received by the receiver may be reported by the last relay, so that in order to distinguish the first data packet or the second data packet sent by different relays, in this embodiment, the relay identifier of the corresponding relay is carried in the first data packet and the second data packet, after the receiver parses the first data packet, the receiver may obtain the first relay identifier, and compare with the binding information maintained by the receiver, and determine that the first data packet is from the binding relay, so as to obtain physiological data of the first data packet and compare with the first quality parameter value. And the receiver determines that the data packet is from an unbound repeater based on the second relay identifier and binding information, and obtains a second quality parameter value therefrom for comparison during repeater switching.
After each time the first data packet or the second data packet is acquired, the receiver performs a comparison between the first quality parameter value and the first threshold value, so as to ensure that the relay switch can be performed in time.
Illustratively, as shown in fig. 5, for example, the telemetry terminal performs 3 times of acquisition of physiological data, namely physiological data 1, physiological data 2 and physiological data 3, respectively, with sequence number 1 being carried when physiological data 1 is broadcast, sequence number 2 being carried when physiological data 2 is broadcast, and sequence number 3 being carried when physiological data 3 is broadcast. The telemetering terminal generates a broadcast signal 1 according to the physiological data 1 and the sequence number 1, each repeater stores the physiological data 1 and the sequence number 1 in a buffer memory after acquiring the broadcast signal 1, and the subsequent physiological data 2 and the sequence number 2, and the physiological data 3 and the sequence number 3 are the same, and the repeated description is omitted.
In addition, in an embodiment, referring to fig. 3, step S40 further includes, but is not limited to, the following steps:
s41, the receiver analyzes the first data packet;
s42, when the analyzed first relay identification is recorded in the binding information, the receiver acquires a comparison serial number, wherein the comparison serial number is the data serial number of the physiological data which is reported to the central monitoring station last time;
s43, when the target serial number is continuous with the comparison serial number, physiological data are sent to the central monitoring station;
S44, when the target sequence number is discontinuous with the comparison sequence number, the receiver determines a missing sequence number between the comparison sequence number and the target sequence number, acquires missing data from the physiological data cached by the binding relay or the unbinding relay based on the missing sequence number, integrates the missing data and the physiological data, and then sends the integrated missing data and the physiological data to the central monitoring station.
It should be noted that, after the receiver acquires the first data packet, specific data in the first data packet may be obtained by a data parsing manner, where the data parsing may be conversion of a data format, or compression and decompression of data, which is not limited herein.
It should be noted that, although the technical solution of this embodiment can realize the noninductive switching of the repeater, the physiological data can be sent to a plurality of available repeaters through the broadcast signal, temporary interference may still occur to cause missed transmission of the physiological data, for example, the patient enters a tunnel or a space with poor signal coverage such as an elevator, if the physiological data is received discontinuously, the central monitoring station may possibly cause an error alarm. Based on this, in this embodiment, after the first data packet is acquired each time, the continuity of the physiological data is determined based on the data sequence number, so as to ensure that the central monitoring station acquires the continuous data.
Specifically, when the first relay identifier analyzed by the receiver is recorded in the binding information, it is determined that the first data packet is sent by the binding repeater, according to the description of the embodiment, the telemetry terminal may carry the target sequence number when broadcasting the physiological data, and each time the target sequence number may be cached in the repeater, or may be cached in the receiver at the same time, based on this, the receiver in this embodiment obtains the comparison sequence number when reporting the physiological data last time from the history record, if the comparison sequence number is continuous with the target sequence number, it is determined that the physiological data reported continuously twice is continuous, no data is lost, and normal physiological data reporting may be performed; if the comparison sequence number is discontinuous with the target sequence number, the missing data needs to be complemented, namely, the missing physiological data and the current physiological data are reported at the same time, and the central monitoring station receives a plurality of continuous physiological data and forms a continuous data sequence with the physiological data acquired last time. The last reported data is the physiological data acquired this time when the data is completed, so that the target sequence number of the physiological data acquired next time can be continuous, and the continuous reliability of the data is ensured.
It should be noted that the number of missing sequence numbers may be arbitrary, and according to the above-mentioned scenes such as entering a tunnel or an elevator, the signal quality of each repeater is poor, so that the switching of the repeater cannot be performed, in this process, physiological data may be acquired for 1 time or multiple times, for example, as shown in fig. 5, the physiological data reported to the receiver last time is sequence number 1, after physiological data with sequence number 2 is acquired in a specific scene, the signal is returned to a scene with better signal coverage to acquire physiological data with sequence number 3 again, and the missing sequence number is sequence number 2; as another example, n times physiological data (n is a natural number greater than 1) are acquired in a particular scene, returning to the scene with better signal coverage, collecting the physiological data with the sequence number of n+1 again, the missing sequence numbers are the sequence numbers 2,3, and. N.
In order to better illustrate the technical solution of continuity verification in this embodiment, a specific example is provided below in conjunction with fig. 5. In the present example, the repeater 1, the repeater 2, and the repeater 3 have acquired 2 times of physiological data (physiological data 1 and physiological data 2, respectively) and have been cached in the respective repeaters, taking the repeater 3 as a binding repeater as an example.
Firstly, the telemetry terminal broadcasts a broadcast signal to a target channel, the broadcast signal carries physiological data 3 and sequence number 3, the repeater 3 generates a first data packet carrying the physiological data 3 and the sequence number 3 and sends the first data packet to a receiver, and the receiver performs continuity verification based on the sequence number 3.
For example, when the acquired comparison serial number is serial number 2, since serial numbers 2 and 3 are continuous, two adjacent data reports are continuous, and physiological data 3 is reported to the central monitoring station.
For another example, when the acquired comparison sequence number is sequence number 1, and the sequence numbers 1 and 3 are discontinuous, the sequence number 2 is taken as a missing sequence number, the receiver requests the physiological data 2 to each repeater, the repeater 1, the repeater 2 and the repeater 3 can feed back the physiological data 2 respectively, and the receiver acquires the physiological data 2 as missing data and reports the missing data and the physiological data 3 to the central monitoring station together.
For another example, when the comparison sequence number cannot be obtained, it can be determined that the physiological data before the sequence number 3 are not uploaded normally, the sequence numbers 1 and 2 are used as missing sequence numbers, the receiver requests the physiological data 1 and the physiological data 2 to each repeater based on the sequence numbers 1 and 2, the repeater 1, the repeater 2 and the repeater 3 can feed back the physiological data 1 and the physiological data 2 respectively, and the receiver obtains the physiological data 1 and the physiological data 2 as missing data and reports the missing data and the missing data to the central monitoring station together with the physiological data 3.
In addition, in an embodiment, referring to fig. 3, before performing step S40, the following steps are further included, but not limited to:
S61, carrying out integrity verification on physiological data;
s62, when the integrity verification result represents that the data is complete, the receiver sends physiological data to the central monitoring station;
and S63, when the integrity verification result indicates that the data is incomplete, the receiver acquires the supplementary data from the physiological data cached by the unbound repeater based on the target sequence number, supplements the supplementary data to the physiological data, and sends the supplementary complete physiological data to the central monitoring station.
It should be noted that, before the data continuity verification is performed, the integrity verification may be performed on the acquired data, which is due to temporary interference when the telemetry terminal reports the data, or the telemetry terminal reaches the coverage edge of the binding repeater, where the signal quality is close to the first threshold, for example, through a medical apparatus with larger interference, which is likely to cause the incompleteness of the acquired data of the binding repeater, for example, a part of the numerical values in the physiological data are lost, and the data format of the physiological data is usually preset and known, so that the integrity verification may be performed on the physiological data, and when the continuity verification is performed according to the description of the above embodiment is continued after the verification is passed, and when the verification is different, the data supplementing operation is performed.
It should be noted that, because the incompleteness of the physiological data is caused by the unstable signal of the binding relay, and each relay caches the physiological data based on the broadcast signal, the supplementary data can be obtained from the unbound relay based on the target serial number as the data pairing basis, so as to ensure that the receiver obtains the complete physiological data.
Illustratively, continuing with the example shown in fig. 5 above, after the repeater 3 transmits the physiological data 3 with the sequence number 3 to the receiver, the receiver verifies the integrity of the physiological data 3, and the receiver transmits the physiological data 3 to the central monitoring station after performing the continuity verification; if the integrity verification of the physiological data 3 by the receiver is not passed, the receiver sends a serial number 3 to the relay 1 and the relay 2, the relay 1 and the relay 2 feed back the missing data of the physiological data 3 sent by the relay 3 to the receiver, and the receiver supplements the physiological data 3 to be complete after obtaining the supplementary data and then carries out subsequent continuity verification.
