[0039] The following describes the embodiments of the present application in conjunction with the drawings in the specification. It should be understood that the embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0040] The embodiments of the present application provide a wireless signal transmission method and system capable of dual signal transmission. Two independent signal transmission modules work together. When the signal quality is good, only a single module is used to transmit data. When the signal is poor, dual modules are used for collaborative transmission, signal strength is enhanced, and different frequency bands are used to reduce packet loss rate, improve transmission reliability, and achieve energy efficiency optimization at the same time. The wireless signal transmission method and system provided in the embodiments of the present application are used in long-distance wireless sensing in energy storage battery management to effectively solve the problems of data packet loss and excessive energy consumption.

[0041] like Figure 1 As shown in FIG. 1 , it is a schematic diagram of an application scenario of a wireless signal transmission system proposed in the present application, which is specifically applied to a scenario in which a battery module sends cell data to a battery management system (BMS) through a wireless sensor node so that the BMS can upload the cell data to a monitoring system / cloud. Figure 1 As shown, the wireless signal transmission system proposed in this application is set between the wireless sensor node and the BMS, and a wireless sensor node is installed on each battery module to collect battery cell data, such as key parameters such as battery cell temperature, voltage, and discharge status, and encapsulate the collected data into a data packet, and transmit the data packet to the BMS and the monitoring platform through a wireless signal. It can be understood that in practical applications, the wireless signal transmission system proposed in this application can also be set between the battery module, that is, the battery cell and the sensor node, or between the BMS and the monitoring system / cloud. If it is set between the battery cell and the wireless sensor node: In this case, dual signal transmission can be used to transmit battery data (such as voltage, current, temperature, etc.) from the sensor node to the centralized processor or monitoring device, in order to improve the stability of data transmission, reduce signal interference and packet loss, and is particularly suitable for situations where the battery pack sensor is far away and the environment is complex and easy to interfere. If it is set between the wireless sensor node and the BMS: In this configuration, the wireless sensor node can transmit the collected battery status data (such as temperature, status information, etc.) to the BMS for real-time monitoring, which can improve the data transmission quality from the wireless sensor node to the BMS and ensure that key data can be accurately transmitted under adverse conditions. It is especially suitable for multi-node management applications to improve the accuracy of data collection and management. If it is set between BMS and monitoring system / cloud: In this type of solution, BMS will transmit data to the monitoring system in the cloud for remote monitoring and management. If there is packet loss or signal instability during data upload, the dual signal transmission method can enhance the reliability of data upload through the backup channel, ensure the real-time and accuracy of remote monitoring, and is especially suitable for scenarios that require long-distance wireless transmission.

[0042] See attached Figure 2 , Figure 2This is a schematic diagram of the main steps of a wireless signal transmission method provided by an embodiment of the present application. The method is applicable to a wireless signal transmission system, which includes at least a main signal transmission module and a backup signal transmission module. After the wireless signal transmission system is started, the main signal transmission module is enabled by default for signal transmission. Figure 2 As shown, the wireless signal transmission method in the embodiment of the present application mainly includes the following steps S11 to S14.

[0043] Step S11: the main signal transmission module starts to transmit signals;

[0044] In this embodiment, taking the wireless signal sender and receiver as the wireless sensor node and BMS connected to the battery cell respectively, the main signal transmission module starting the signal transmission can be understood as the main signal transmission module transmitting the signal from the wireless sensor node to the BMS.

[0045] Step S12: When it is detected that the current signal quality does not meet the preset condition, the backup signal transmission module is started;

[0046] Step S13: The backup signal transmission module and the main signal transmission module cooperate to perform signal transmission according to a preset task allocation strategy;

[0047] Step S14: When it is monitored that the current signal quality meets the preset condition, the standby signal transmission module enters a low power consumption standby mode.

[0048] It should be understood that the above steps S11 to S14 are not used to limit the execution order of the method of the present application, but are only exemplary illustrations of the main steps included in the wireless signal transmission method of the present application. In addition, in step S14, when it is monitored that the current signal quality meets the preset conditions, the backup signal transmission module can also be directly turned off, leaving only the main signal transmission module to continue transmitting the signal.

[0049] In a specific implementation of the above steps S11 to S14, the current signal quality can be measured based on signal strength and signal-to-noise ratio. Accordingly, the wireless signal transmission method of the embodiment of the present application also includes: the wireless signal transmission system acquires the signal strength and signal-to-noise ratio in real time, and determines the current signal quality based on the signal strength and the signal-to-noise ratio; when it is monitored that the signal strength is less than a first preset threshold or the signal-to-noise ratio is less than a second preset threshold, the current signal quality is determined to not meet the preset condition; correspondingly, when it is monitored that the signal strength is not less than the first preset threshold and the signal-to-noise ratio is not less than the second preset threshold, the current signal quality is determined to meet the preset condition.

[0050] Exemplarily, the wireless signal transmission system may also be configured with a signal quality monitoring module and a control module, wherein the signal quality monitoring module is used to monitor the signal quality in transmission in real time and feed back to the control module after the wireless signal system is started. For example, the signal quality monitoring module is used to monitor parameters such as signal strength (RSS I) and signal-to-noise ratio (SNR) in real time. When RSS I ≥ -85dBm, it indicates that the signal quality is good, and when RSS I < -85dBm, it indicates that the signal quality is poor; when SNR ≥ 25dB, it indicates that the signal quality is good, and when SNR < 25dB, it indicates that the signal quality is poor. When the signal quality is poor, the control module may control the backup signal transmission module to start, and cooperate with the main signal transmission module to transmit data packets.

[0051] In practical applications, the packet loss rate can also be used as an indicator to measure the signal quality. Accordingly, the wireless signal transmission method of the embodiment of the present application also includes: the wireless signal transmission system obtains the packet loss rate of the data packet transmitted by the main signal transmission module, and when it is detected that the packet loss rate is greater than the third preset threshold, the backup signal transmission module is triggered to start.

[0052] Based on the above steps S12 and S13, after the backup signal transmission module is started, the specific implementation method of the backup signal transmission module and the main signal transmission module jointly performing signal transmission according to a pre-set task allocation strategy can be: the backup signal transmission module is started and transmits the same data packet together with the main signal transmission module.

[0053] Or it can be: the backup signal transmission module is started, the main signal transmission module transmits a part of the data packet, and the backup signal transmission module transmits the remaining data of the data packet; wherein, the part of the data packet and the remaining data of the data packet are obtained by splitting all the data in the data packet according to a pre-set task allocation strategy.

[0054] Alternatively, it may be that: the backup signal transmission module is started, the main signal transmission module transmits a data packet, and the backup signal transmission module transmits verification data corresponding to the data packet.

[0055] In a specific implementation of steps S11 to S14, the main signal transmission module and the backup signal transmission module respectively use different frequency bands for data transmission. For example, the main signal transmission module uses a low-frequency and long-distance transmission protocol for signal transmission, and the backup signal transmission module uses a high-frequency and short-distance transmission protocol for signal transmission.

[0056] In the specific implementation of the above steps S11 to S14, the main signal transmission module and / or the backup signal transmission module can also dynamically adjust the signal transmission power according to the current signal quality. For example, a corresponding relationship mapping table between signal strength and signal transmission power is pre-stored in the wireless signal transmission system, and when the current signal quality is detected to be poor, the signal transmission power is adjusted based on the corresponding relationship mapping table.

[0057] In the specific implementation of the above steps S11 to S14, when the main signal transmission module starts to transmit signals and the standby signal transmission module is in a low-power standby mode, the wireless signal transmission system can also predict the signal quality of the signal transmission in the next time period based on the current signal quality. If the predicted signal quality does not meet the preset condition, the standby signal transmission module is triggered to start in advance. In practical applications, the specific implementation of the wireless signal transmission system predicting the signal quality of the signal transmission in the next time period based on the current signal quality can be predicted by a pre-configured algorithm model. For example, the algorithm model can be obtained by model training based on the random forest machine learning model and the data used to characterize the signal quality obtained by historical monitoring. Further, it can be set to start the algorithm model every fixed period (such as 100ms). The algorithm model predicts the signal fluctuation trend of the next time period based on the current signal quality to obtain the signal quality of the next time period. If the predicted signal quality of the next time period is close to the threshold, the standby signal transmission module can be started in advance to deal with the sudden interference signal or the sudden deterioration of the signal transmission quality in time.

[0058] exist Figure 2 Based on the wireless signal transmission method shown, Figure 3 As shown, the embodiment of the present application also provides a specific implementation method for starting dual signal transmission based on a wireless signal transmission system. As shown in the figure, it mainly shows the switching process of the wireless signal transmission system switching from signal transmission with a single main signal transmission module to dual signal transmission coordinated by the main signal transmission module and the backup signal transmission module. In this process, the execution subject can be understood as the wireless signal transmission system or a control module configured in the system. As shown in the figure, it mainly includes the following steps 101 to 107.

[0059] Step 101: The main signal transmission module transmits a data packet in a wireless signal manner;

[0060] Specifically in this embodiment, the data packets transmitted by the main signal transmission module come from the data packets sent by the wireless sensor node. During the data transmission process, each data packet can be pre-set to have the same size, such as setting the data packet size to 64 bytes. Each data packet is accompanied by a unique sequence number (for example, packet 1, packet 2, packet 3...) during transmission, thereby ensuring that the receiver can reorganize the data in the correct order.

[0061] Step 102: Determine whether the signal strength is less than a first preset threshold, if yes, execute step 107, otherwise execute step 103;

[0062] For example, the first preset threshold is -85dBm.

[0063] Step 103: Determine whether the signal-to-noise ratio is less than a second preset threshold, if yes, execute step 107, otherwise execute step 104;

[0064] For example, the second preset threshold is 25 dB.

[0065] Step 104: Check whether the numbers of the data packets are continuous, if yes, return to step 101, otherwise, go to step 105;

[0066] Step 105: determine whether the number of retransmissions of the data packet is greater than a preset number. If yes, it indicates that the data transmission has failed, and step 106 is executed. Otherwise, the data is retransmitted, and the process returns to step 101.

[0067] For example, the preset number of times is 3 times.

[0068] It is understandable that when it is determined that data retransmission is required, the wireless signal transmission system sends a signal indicating the need for data retransmission to the signal sender (such as a wireless sensor node) through the main signal transmission module, so that the sender can resend the last sent data packet.

[0069] Step 106: Determine whether the packet loss rate reaches a third preset threshold, if yes, execute step 107, otherwise return to execute step 101;

[0070] For example, the third preset threshold is 1%.

[0071] Step 107: The backup signal transmission module is started to cooperate with the main signal transmission module to transmit data packets.

[0072] In this embodiment, the coordination between the backup signal transmission module and the signal transmission module can be specifically as follows: the main signal transmission module continues to transmit the main data in a low-power manner, while the backup signal transmission module is responsible for transmitting redundant data or verification data, so that the receiving end (such as BMS) can ensure the integrity of the data by comparing and synchronizing the signals received from different frequency bands of the two signal transmission modules.

[0073] See attached Figure 4 , is a schematic diagram of the composition architecture of a wireless signal transmission system provided in an embodiment of the present application. As shown in the figure, the wireless signal transmission system includes a signal quality monitoring module 201, a control module 202, a main signal transmission module 203 and a backup signal transmission module 204, wherein the functions of each module are described as follows:

[0074] The signal quality monitoring module 201 is used to monitor the current signal quality in real time and send the monitoring result to the control module 202 .

[0075] In this embodiment, the signal quality monitoring module 201 can be configured to detect the signal strength (RSS I), signal-to-noise ratio (RNR) and packet loss rate (PER) of the wireless signal in real time, and judge the current signal quality based on some pre-set thresholds to determine the monitoring result, and send the monitoring result to the control module 202; or, the signal quality monitoring module 201 directly sends the detected RSS I, RNR and PER as the monitoring result to the control module 202, and the control module 202 judges the current signal quality based on some pre-set thresholds.

[0076] The main signal transmission module 203 and the backup signal transmission module 204 are used to perform signal transmission under the control of the control module 202 .

[0077] In this embodiment, in order to avoid co-frequency interference, the main signal transmission module 203 and the backup signal transmission module 204 can be configured to use different frequency bands to transmit signals. For example, the main signal transmission module 203 can use low-frequency long-distance transmission (such as LoRa or Sub-GHz), while the backup signal transmission module uses high-frequency short-distance transmission (such as Wi-Fi or 5GHz). This can avoid signal interference caused by the same frequency band and improve transmission efficiency. The working frequency bands of the two signal transmission modules are completely independent, and the signal sending and receiving time are regulated by software algorithms to ensure that there will be no signal conflict.

[0078] It can be understood that the main signal transmission module 203 and the backup signal transmission module 204 can be implemented based on existing wireless communication technologies (such as LoRa, Zigbee, NB-I oT, etc.), and when the signal quality is good, the main signal transmission module 203 can be configured to adopt a low power consumption mode for signal transmission and be responsible for the main data transmission task. When the signal quality is poor, the backup signal transmission module 204 is activated to transmit data in coordination with the main signal transmission module 203 to supplement possible packet loss data. At this time, the wireless signal transmission system can be understood as being in a dual signal transmission working mode.

[0079] The control module 202 is used to control the main signal transmission module 203 to start signal transmission when the system is turned on. When the monitoring result sent by the signal quality monitoring module 201 indicates that the current signal quality does not meet the preset conditions, the backup signal transmission module 204 is controlled to start and cooperate with the main signal transmission module 203 to perform signal transmission according to a preset task allocation strategy; when the monitoring result sent by the signal quality monitoring module 201 indicates that the current signal quality meets the preset conditions, the backup signal transmission module 204 is controlled to enter a low-power standby mode.

[0080] Furthermore, the control module 202 in this embodiment can also be used to dynamically adjust the signal transmission power of the main signal transmission module and / or the backup signal transmission module 204 according to the current signal quality. Accordingly, the main signal transmission module and / or the backup signal transmission module adjusts its own signal transmission power under the control of the control module.

[0081] Furthermore, the control module 202 in this embodiment can also be used to predict the signal quality of signal transmission in the next time period based on the current signal quality when the main signal transmission module starts to transmit signals and the backup signal transmission module is in a low-power standby mode, and if the predicted signal quality does not meet the preset conditions, the backup signal transmission module is triggered to start. For example, a random forest machine learning model is pre-configured in the control module 202, and the prediction function of the quality signal can be realized based on the model. The specific implementation method can refer to the description of the method embodiment.

[0082] After adopting the wireless signal transmission system provided by the embodiment of the present application, when the signal quality during transmission is poor, the backup signal transmission module in the system automatically starts and works in conjunction with the main signal transmission module to ensure data reliability through multiple frequency bands and enhanced transmission power. At the same time, the backup signal transmission module automatically enters the standby state when the signal quality is restored, which can effectively reduce system energy consumption.

[0083] It should be understood that since the setting of each module is only for illustrating the functional units of the device of the present invention, the physical devices corresponding to these modules may be the processor itself, or a part of the software in the processor, a part of the hardware, or a part of the combination of software and hardware. Therefore, the number of each module in the figure is only schematic.

For ease of explanation, only the parts related to the embodiment of the present invention are shown.
