Description

Technical Field

[0001] This invention relates to the field of communication control, and in particular to a blood pressure monitor communication method, device, and blood pressure monitor. Background Technology

[0002] Most blood pressure monitors on the market are currently powered by dry cell batteries for ease of use by the elderly. However, dry cell batteries have a relatively low energy density. The conventional method is to increase the voltage to solve the problem of product malfunction caused by voltage drops. Therefore, when the battery is not properly distributed, the blood pressure monitor's power will be depleted quickly.

[0003] Currently, conventional blood pressure monitors often require cellular communication. However, existing cellular communication modules often use a always-on method to maintain communication, which consumes a lot of power and is not an efficient way to allocate battery power. Moreover, in areas with poor signal, data is often not transmitted successfully, requiring multiple transmissions, which also increases the power consumption of the blood pressure monitor. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a blood pressure monitor communication method, device and blood pressure monitor to optimize the distribution of communication energy according to the actual use scenario of the blood pressure monitor and improve the battery life of the blood pressure monitor.

[0006] Furthermore, prior to the steps of activating the radio frequency unit of the communication module and monitoring the current signal strength if blood pressure measurement is detected to be completed, the method further includes: activating the communication module when the blood pressure monitor is detected to be powered on for blood pressure measurement.

[0007] Furthermore, the step of searching for the corresponding estimated transmission time from the pre-stored historical transmission records based on the current signal strength includes: searching for the historical signal strength that is closest to the current signal strength from the pre-stored historical transmission records; and determining the historical transmission time corresponding to the closest historical signal strength as the estimated transmission time.

[0008] Furthermore, it also includes acquiring the level change of the status pin of the cellular communication module; if a level change of the status pin of the communication module is detected, then searching for the historical signal strength that is closest to the current signal strength from the pre-stored historical transmission records.

[0009] Furthermore, the step of pre-storing historical transmission records includes: pre-acquiring standard communication times for different signal strengths and storing the signal strengths in association with the standard communication times; generating historical transmission records.

[0010] Furthermore, the method also includes: determining whether the current signal strength is greater than a preset signal strength threshold; if not, shutting down the radio frequency unit of the communication module.

[0011] Furthermore, the step of determining the signal strength threshold includes: obtaining all historical signal strengths and corresponding failure counts of measurement data upload failures in historical transmission records; finding the historical signal record with the largest failure count exceeding a preset threshold, and determining the largest historical signal record as the signal strength threshold.

[0012] Furthermore, the historical transmission records also include historical location information, and the method further includes: obtaining the current location information of the blood pressure monitor, determining whether the current location information is consistent with the historical location information; if not, updating the signal strength threshold corresponding to the current location information.

[0013] Secondly, embodiments of the present invention provide a blood pressure monitor communication device, comprising: a monitoring module, configured to activate the radio frequency unit of the communication module and monitor the current signal strength if blood pressure measurement is detected as complete; a lookup module, configured to look up the corresponding estimated transmission time from pre-stored historical transmission records based on the current signal strength; the historical transmission records include historical signal strength and historical transmission time corresponding to multiple data transmissions; an upload module, configured to upload the measurement data to the background if the estimated transmission time corresponding to the current signal strength is less than a preset time threshold; and a switch module, configured to deactivate the radio frequency unit if the estimated transmission time corresponding to the current signal strength is greater than the preset time threshold, until the estimated transmission time corresponding to the current signal strength is less than the preset time threshold, and then activate the radio frequency unit to upload the measurement data to the background.

[0014] Thirdly, embodiments of the present invention provide a blood pressure monitor, which includes a blood pressure monitor body and the blood pressure monitor communication device described above, wherein the blood pressure monitor communication device can execute instructions to implement any of the above methods.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Currently, most blood pressure monitors on the market are powered by dry cell batteries for ease of use by the elderly. However, dry cell batteries have a relatively low energy density (voltage drops by 0.8V when operating in cellular mode). The conventional method is to increase the voltage to address product malfunctions caused by voltage drops. Therefore, when battery usage is not properly managed, the blood pressure monitor's power will be depleted quickly. How to reduce the power consumption of blood pressure monitors and enhance their battery life is a key technical challenge when using dry cell batteries.

[0027] Based on this, the blood pressure monitor communication method, device, and electronic device provided in this embodiment of the invention can simultaneously start the cellular module when powering on for measurement, and disable the radio frequency (RF) by default when the cellular module is turned on. The RF is only turned on after a request to turn on the RF is received after the measurement is completed. Furthermore, the signal strength and data transmission completion time in the current environment can be recorded multiple times in advance. A lookup table is performed based on the signal strength and data transmission time. If the time exceeds a preset limit, the network search stage is skipped, and the detection is performed again in the next test. When the signal strength meets the corresponding signal strength in the preset signal strength table, the network search operation is performed. This method can detect the signal strength received by the cellular module multiple times and determine whether data needs to be transmitted based on different signal strength environments. Therefore, it can avoid long-term cellular communication and reduce energy consumption.

[0028] To facilitate understanding of this embodiment, a blood pressure monitor communication method disclosed in this embodiment of the invention will first be described in detail.

[0029] This invention provides a blood pressure monitor communication method. Figure 1 A flowchart of a blood pressure monitor communication method provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method specifically includes the following steps:

[0030] Step S101: If the blood pressure measurement is detected as complete, the radio frequency unit of the communication module is turned on and the current signal strength is monitored.

[0031] In practical applications, because the 4G communication signal of the blood pressure monitor may affect the accuracy of the measurement results, conventional blood pressure monitor control methods typically place 4G operation after the measurement is completed, which is a relatively time-consuming process. Therefore, optimizing cellular communication can reduce power consumption.

[0032] Therefore, the communication module can be started simultaneously during power-on measurement, but the RF unit can be set to be disabled by default, and only turned on upon receiving a request after the measurement is completed; this can effectively save 8 seconds of communication module power-on time. This speeds up module initialization waiting and avoids the inaccuracy of measurement results due to 4G RF interference.

[0033] Therefore, in specific applications, before the step of monitoring the current signal strength, the method may further include: activating the communication module when the blood pressure monitor is detected to be powered on for blood pressure measurement.

[0034] Step S103: If the current signal strength is greater than the signal strength threshold, find the corresponding estimated transmission time from the pre-stored historical transmission records; the historical transmission records include the historical signal strength and historical transmission time corresponding to multiple data transmissions.

[0035] In practical applications, the step of pre-storing historical transmission records can be achieved by the following steps A1-A2:

[0036] Step A1: Pre-obtain the standard communication time for different signal strengths, and associate and store the signal strength with the standard communication time;

[0037] Step A2: Generate historical transmission records.

[0038] In practical applications, the step of finding the corresponding estimated transmission time from pre-stored historical transmission records based on the current signal strength can be achieved by the following steps B1-B2:

[0039] Step B1: Find the historical signal strength that is closest to the current signal strength from the pre-stored historical transmission records;

[0040] Step B2: Determine the historical transmission time corresponding to the closest historical signal strength as the expected transmission time.

[0041] At the same time, it can also determine whether the current signal strength is greater than the preset signal strength threshold;

[0042] If not, then shut down the radio frequency unit of the communication module.

[0043] Specifically, if no corresponding historical data is found in the historical transmission records, the blood pressure monitor's startup data is sent, and the current signal strength and corresponding transmission time are recorded. If data transmission fails, the device is turned off, and data transmission is restarted after a half-day interval. If data transmission fails after a preset number of attempts, the signal strength is set to a signal strength threshold, and the required time is recorded.

[0044] In practical applications, the above-mentioned judgment of the communication module start command can be used to execute the process of finding the historical signal strength that is closest to the current signal strength from the pre-stored historical transmission records.

[0045] Specifically, if a change in the level of the status pin of the communication module is detected, the system searches for the historical signal strength that is closest to the current signal strength from the pre-stored historical transmission records.

[0046] Step S105: If the estimated transmission time corresponding to the current signal strength is less than the preset time threshold, upload the measurement data to the background.

[0047] If the current signal strength meets the signal strength threshold, it proves that the blood pressure monitor is in a good communication environment, and the measurement data can be directly uploaded to the backend.

[0048] Step S107: If the estimated transmission time corresponding to the current signal strength is greater than a preset time threshold, shut down the communication module until the estimated transmission time corresponding to the current signal strength is less than the preset time threshold, then turn on the radio frequency unit to upload the measurement data to the background.

[0049] Specifically, a lookup table comparison can be performed based on the current signal strength and the data transmission time. Different transmission strategies can be adopted according to the preset transmission time. For longer transmission times, when the signal strength is detected again to be close to the signal strength threshold corresponding to the longer transmission time, the communication function of the blood pressure monitor is stopped, and multiple time periods are used to detect and determine whether data needs to be transmitted again.

[0050] The above method allows the cellular module to be started simultaneously during power-on measurement. The cellular module is powered off by default when it is turned on, and only turns on the RF after receiving a request to turn it on upon completion of the measurement. Furthermore, it can pre-record signal strength and data transmission completion time under the current environment multiple times. A lookup table is performed based on the signal strength and data transmission time. If the time exceeds a preset limit, the network search phase is skipped, and the test is repeated on the next attempt. When the signal strength matches the preset signal strength table, a network search operation is performed. This method can repeatedly test the signal strength received by the cellular module and determine whether data transmission is necessary based on different signal strength environments. Therefore, it avoids forcibly searching and transmitting data even with poor network conditions, greatly reducing power consumption caused by poor network performance.

[0051] Based on the above embodiments, Figure 2 A flowchart of another blood pressure monitor communication method is shown, mainly describing the process of determining whether the current signal strength is greater than a preset signal strength threshold, such as... Figure 2 As shown, the method specifically includes the following steps:

[0052] Step S201: If the blood pressure measurement is detected to be complete, the radio frequency unit of the communication module is turned on and the current signal strength is monitored;

[0053] Step S202: Obtain all historical signal strengths and corresponding failure counts from the historical transmission records where measurement data upload failed.

[0054] Specifically, when no historical transmission record is found in the blood pressure monitor query, the system sends the blood pressure monitor's startup data, recording the current signal strength and corresponding transmission time. If data transmission fails, the device is shut down, and data transmission is restarted after a preset time interval. If transmission fails after a preset number of attempts, the system records the time required for each failed signal strength.

[0055] Step S203: Find the largest historical signal record among the number of failures that is greater than a preset threshold, and determine the largest historical signal record as the signal strength threshold;

[0056] Based on the above steps, the signal strength of each failed signal can be filtered, and the maximum value can be selected as the signal strength threshold. If the signal strength is less than this threshold, it is considered a poor communication environment.

[0057] Step S204: The historical transmission record also includes historical location information. Obtain the current location information of the blood pressure monitor and determine whether the current location information is consistent with the historical location information.

[0058] Meanwhile, since the location of the base station will not change, the signal strength at the same location may remain very weak, such as in remote areas or areas with poor infrastructure. Therefore, if the corresponding signal strength threshold is detected repeatedly, data will be sent once every half day. The specific time interval is not limited here. When multiple attempts fail, the blood pressure monitor's preset screen will display a message to remind the user to move the device to a place with a better signal.

[0059] Step S205: If not, update the signal strength threshold corresponding to the current location information;

[0060] In practical applications, the preset signal strength threshold is not always fixed. The blood pressure monitor can refresh the above-mentioned update time threshold condition every week or when the latitude and longitude of the device are detected to change, and record the corresponding new signal strength threshold.

[0061] If the blood pressure monitor is consistently located in an area with poor signal strength, it can update and record multiple preset signal strength thresholds. The device will perform data statistics, and if a preset signal strength threshold is frequently encountered a preset number of times, it will be marked as a priority and connection attempts will cease. The screen will display a reminder, or the server backend personnel will contact the user to guide them to use the device in a better environment.

[0062] Step S206: If the current signal strength is greater than the signal strength threshold, find the corresponding estimated transmission time from the pre-stored historical transmission records; the historical transmission records include the historical signal strength and historical transmission time corresponding to multiple data transmissions.

[0063] Step S207: If the estimated transmission time corresponding to the current signal strength is less than the preset time threshold, upload the measurement data to the background.

[0064] Corresponding to the above method embodiments, this invention provides a blood pressure monitor communication device. Figure 3 A schematic diagram of a blood pressure monitor communication device is shown, such as... Figure 3 As shown, the blood pressure monitor communication device includes:

[0065] The monitoring module 301 is used to activate the radio frequency unit of the communication module and monitor the current signal strength if the blood pressure measurement is detected to be completed.

[0066] The lookup module 302 is used to look up the corresponding estimated transmission time from the pre-stored historical transmission records based on the current signal strength; the historical transmission records include the historical signal strength and historical transmission time corresponding to multiple data transmissions;

[0067] The upload module 303 is used to upload the measurement data to the backend if the estimated transmission time corresponding to the current signal strength is less than a preset time threshold.

[0068] The switch module 304 is used to turn off the radio frequency unit if the expected transmission time corresponding to the current signal strength is greater than a preset time threshold, and turn on the radio frequency unit to upload the measurement data to the background when the expected transmission time corresponding to the current signal strength is less than the preset time threshold.
