[0126] Technical concept

[0127] Physical devices such as electronic devices, electronic components, and electronic systems include power supply modules and capacitors. These power supply modules and capacitors provide power to other modules within the physical device besides the power supply module itself.

[0128] The inventors of this disclosure have discovered that configuring a power supply module and capacitors in a physical device to supply power to other modules ensures that the other modules have sufficient power to operate normally, thereby ensuring the stable operation of the physical device. However, configuring a power supply module and capacitors in a physical device increases the cost of the device, meaning that the cost of stable operation of the physical device is higher.

[0129] The power supply module connects to an external power source to supply power to the modules within the physical device, making it an essential component. To reduce the cost of the physical device, the inventors considered removing the capacitors. However, removing the capacitors leaves the other modules powered solely by the power supply module, causing a voltage drop in the power supply module. When the voltage drops to a certain value, the electronic components within the physical device may be damaged due to the low voltage. To prevent this damage, the physical device restarts when the power supply module voltage drops to a certain level.

[0130] Based on this, the inventors of this disclosure conceived of detecting the voltage of the power supply module. If the voltage of the power supply module drops, the operating mode of the target module powered by the power supply module is adjusted so that the voltage of the power supply module is greater than the restart voltage, thereby preventing the physical device where the power supply module is located from restarting. This achieves stable operation of the physical device while reducing the stable operating cost of the physical device, and ensures that users can use the functions of the physical device normally, thus improving the user experience.

[0131] Schematic diagram of the data transmission system

[0132] Reference Figure 1-1 The data transmission system 100 includes a power supply module 110, which connects to multiple other modules 120. These other modules 120 include, but are not limited to, communication modules, display modules, indicator light modules, button modules, HBS (Home Bus System) modules, and alarm modules. Communication modules may be, for example, Wi-Fi modules (mobile hotspot modules), 4G communication modules, or 5G communication modules, and alarm modules may be, for example, buzzers.

[0133] The power supply module 110 includes connecting wires (not shown) and a power converter (not shown). The connecting wires connect to an external power source. When the power supply module 110 supplies power to other modules 120, the power converter converts the current supplied by the external power source into the current required by the other modules 120. For example, if the voltage of the DC power supplied by the external power source is 16V, the 16V DC power is converted by the power converter to obtain the 3V DC power required by the other modules 120.

[0134] Furthermore, refer to Figure 1-2The data transmission system 100' may be equipped with an energy storage module 130. The energy storage module 130 may be a low-capacity energy storage module. A low-capacity energy storage module refers to an energy storage module whose maximum energy storage capacity is lower than the preset storage capacity. For example, a low-capacity energy storage module may be a low-capacity capacitor. Low-capacity capacitors have lower costs. The capacity values ​​of low-capacity capacitors include, but are not limited to, 0.22pF, 0.33pF, 0.47pF, 0.68pF, 2.2pF, 3.3pF, 4.7pF, 6.8pF, 10pF, 15pF, 20pF, 22pF, 33pF, 47pF, 68pF, 85pF, and 100pF. The preset storage capacity can be selected from 0.22pF, 0.33pF, 0.47pF, 0.68pF, 2.2pF, 3.3pF, 4.7pF, 6.8pF, 10pF, 15pF, 20pF, 22pF, 33pF, 47pF, 68pF, 85pF, and 100pF. For example, 22pF can be selected as the preset storage capacity. The power supply module 110' is connected to the energy storage module 130, and the power supply module 110' supplies power to the energy storage module 130, enabling the energy storage module 130 to store electrical energy. The energy storage module 130 is connected to other modules 120', so that both the energy storage module 130 and the power supply module 110' can supply power to the other modules 120'.

[0135] Furthermore, the power supply module includes one or more power converters. If the other modules connected to the power supply module require the same current and voltage, then the power supply module only needs one power converter. If the other modules connected to the power supply module require different current and voltage, then the power supply module needs to have multiple power converters to meet the different current and voltage requirements of the other modules. For details, refer to... Figure 1-3 The communication module 121 requires 3V, the alarm module 122 requires 6V, and the display module 123 requires 12V. The power converter 111 in the power supply module 110 first converts the 16V current provided by the external power supply to 12V, and then transmits the 12V current to the display module 123 and the power converter 112 respectively. The power converter 112 converts the 12V current to 6V, and transmits the 6V current to the alarm module 122 and the power converter 113 respectively. The power converter 113 converts the 6V current to 3V, and then transmits the 3V current to the communication module 121.

[0136] exist Figure 1-1In the data transmission system 100 shown, only the power supply module 110 supplies power to the other modules 120. When the power consumption of the other modules 120 is high, the voltage of the power supply module 110 will drop. When the voltage of the power supply module 110 reaches the restart voltage, the power supply module 110 will restart. The restart of the power supply module 110 will cause the data transmission system 100 to restart along with the restart of the power supply module 110.

[0137] exist Figure 1-2 In the data transmission system 100', since the energy storage module 130 is a low-capacity energy storage module, even when the power supply module 110 and the energy storage module 130 supply power to the other modules 120' while they are running, if the power consumption of the other modules 120' is high, the voltage of the power supply module 110' will be reduced, causing the voltage of the power supply module 110' to reach the restart voltage and restart, resulting in the data transmission system 100' restarting along with the restart of the power supply module 110'.

[0138] To prevent the data transmission system from restarting, the data transmission system obtains the voltage of the power supply module. If the voltage of the power supply module drops, the operating mode of other modules is adjusted so that the voltage of the power supply module is greater than the restart voltage.

[0139] Example

[0140] The following is combined Figure 1-1 , Figure 1-2 as well as Figure 1-3 The control methods disclosed herein are described in detail.

[0141] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the control method disclosed herein. The control method includes the following steps:

[0142] Step S201: Obtain the voltage of the power supply module.

[0143] In this embodiment, the executing entity is a data transmission system. The data transmission system can be any component, device, or apparatus with data transmission functionality. Furthermore, the data transmission system can be a system composed of one or more components, one or more devices, or one or more apparatuses. For ease of description, the term "system" will be used to refer to the data transmission system below.

[0144] The system includes a power supply module that powers other modules. Because the system lacks an energy storage module or uses a low-capacity one, the high power consumption of other modules during operation causes a voltage drop in the power supply module. If the power supply module's voltage drops to the restart voltage, it will restart, causing the entire system to restart. The restart voltage refers to the voltage at which the power supply module transitions from the running state to the restart state. For example, if the power supply module restarts when its voltage drops to 2.5V, the restart voltage is 2.5V.

[0145] It should be noted that when no energy storage module is set in the system, "other modules" refers to any module in the system other than the power supply module; when a low-capacity energy storage module is set in the system, "other modules" refers to any module in the system other than the power supply module and the energy storage module.

[0146] To avoid system restarts, the system acquires the voltage of the power supply module in real time or periodically. In one example, the voltage of the power supply module is detected by the power converter, and the system acquires the voltage of the power supply module transmitted by the power converter. In another example, the system includes a component for current detection of the power supply module. Since the power supply module's power is its rated power, its voltage can be calculated from the current and rated power. For example, given the rated power P = UI, where U is voltage and I is current, after acquiring the current and rated power of the power supply module, the system calculates the voltage U of the power supply module based on P = UI, the rated power P, and the current I.

[0147] In step S202, in response to the voltage drop of the power supply module, the operating mode of the target module supplied by the power supply module is adjusted so that the voltage of the power supply module is greater than the restart voltage.

[0148] The system acquires the voltage of the power supply module in real time or at regular intervals. It can determine whether the voltage of the power supply module has decreased by acquiring multiple voltage readings. Specifically, if the voltage of the power supply module currently acquired by the system is lower than the voltage acquired in the last instance, it can be determined that the voltage of the power supply module has decreased.

[0149] When the system detects a voltage drop in the power supply module, it will adjust the operating mode of the target module supplied by the power supply module to ensure that the voltage of the power supply module is greater than the restart voltage.

[0150] Furthermore, the voltage drop in the power supply module may be small, which will not cause the system to restart, and the system does not need to adjust the operating mode of the target module. Based on this, the operating mode of the target module can be adjusted through the following example.

[0151] In one example, when the voltage of the power supply module drops, the system determines whether the voltage has dropped to the protection voltage. If the voltage drops to the protection voltage, there is a risk of system restart, so the system adjusts the operating mode of the target module. The protection voltage can be set based on the restart voltage; for example, the protection voltage can be obtained by adding a fixed value to the restart voltage, meaning the protection voltage is greater than the restart voltage. For instance, if the restart voltage is 2.5V, the protection voltage can be set to 3V.

[0152] In another example, when the voltage of the power supply module drops, the system obtains the voltage difference between the currently obtained voltage and the previously obtained voltage. If the voltage difference is greater than a preset voltage difference, the voltage drop of the power supply module is significant, and the system is at risk of restarting. Therefore, the operating mode of the target module is adjusted. For example, if the maximum voltage drop of the power supply module per unit time is 0.3V, a preset voltage difference can be set based on 0.3V, for example, setting 0.25V as the preset voltage difference, meaning the preset voltage difference is less than the maximum voltage drop. If the voltage difference calculated by the system for the power supply module is greater than 0.25V, the power supply module is at risk of restarting, and the system is also at risk of restarting. The aforementioned unit time can be any suitable value, such as 2 milliseconds.

[0153] In another example, when the voltage of the power supply module drops, the system obtains the duration of the voltage drop. If the duration of the voltage drop exceeds a preset duration, the system risks restarting, and the system adjusts the operating mode of the target module. The preset duration can be any suitable value; for example, the preset duration is 1 second, meaning that if the voltage drop of the power supply module lasts longer than 1 second, the operating mode of the target module will be adjusted.

[0154] In another example, if the voltage of the power supply module drops, the voltage difference between the currently acquired voltage and the previously acquired voltage is greater than a preset voltage difference, and the duration of the voltage drop is longer than a preset duration, and it is determined that the system is at risk of restarting, then the operating mode of the target module is adjusted.

[0155] The target module mentioned above refers to other modules that are powered by the power supply module. There are several ways to determine the target module; please refer to the following example for details.

[0156] In one example, the target module is any other module that is powered by the power supply module.

[0157] In another example, the system determines the power consumption of each other running module. Modules with higher power consumption cause a significant drop in the power supply module's voltage, thus these modules are identified as target modules. "Modules with higher power consumption" refers to those whose power consumption exceeds a preset power consumption. The power consumption of other modules can be determined through their operating parameters. For example, if the target module is a display module, the display brightness is obtained, and the power consumption of the display module is determined based on the brightness; the higher the brightness, the higher the power consumption of the display module.

[0158] In another example, the system determines other modules that can be stopped from running. These other modules can be those that do not hinder the stable operation of the system. For example, if the indicator light module and the alarm module do not affect the stable operation of the system, then the indicator light module and the alarm module can be used as target modules.

[0159] The system can also adjust the operating mode of the target module by reducing its power consumption. For example, if the target module is a display module and its current operating mode is daytime display, the system can switch the display module from daytime display to nighttime display. In other words, by using nighttime display, the display brightness of the display module is reduced, thereby reducing the power consumption of the display module.

[0160] It should be noted that after the target module's operating mode is adjusted, the voltage changes in the power supply module include several variations, as detailed below:

[0161] The first scenario: After the target module's operating mode is adjusted, the voltage of the power supply module increases;

[0162] The second method: After the target module's operating mode is adjusted, the voltage of the power supply module remains unchanged;

[0163] The third scenario: After the target module's operating mode is adjusted, the power supply module's voltage first drops and then rises, and the minimum value after the voltage drop is greater than the restart voltage.

[0164] The fourth type: After the target module's operating mode is adjusted, the voltage of the power supply module alternately decreases and increases, and the minimum value after each voltage decrease is greater than the restart voltage.

[0165] The control method provided in this embodiment can improve the user experience for the following reasons:

[0166] When the voltage of the power supply module in the system drops, it will cause the power supply module to restart. If the power supply module restarts, the system will also restart. When the system is configured to display the module, a system restart will cause the display module to flicker, degrading the user experience. The method provided in this embodiment ensures that the voltage of the power supply module is greater than the restart voltage, preventing the power supply module from restarting, thereby preventing the system from restarting, and ultimately preventing the display module from flickering, thus improving the user experience.

[0167] In this embodiment, the voltage of the power supply module of the data transmission system is obtained. When the voltage of the power supply module drops, the operating mode of the target module supplied by the power supply module is adjusted so that the voltage of the power supply module is greater than the restart voltage, thus preventing the power supply module from restarting. This prevents the data transmission system from restarting along with the power supply module. In other words, while reducing the operating cost of the system by supplying power to each module in the data transmission system through the power supply module, the stable operation of the data transmission system is ensured. This ensures that all functions of the data transmission system can be used normally, improving the user experience. In other words, the data transmission system has the advantages of low-cost operation, high operational stability, and improved user experience.

[0168] Reference Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the control method disclosed herein, based on Figure 2 In the embodiment shown, step S202 includes:

[0169] In step S301, in response to the voltage drop of the power supply module, the communication module powered by the power supply module is controlled to send data at a target interval to ensure that the voltage of the power supply module is greater than the restart voltage.

[0170] During system operation, data is transmitted to external devices via the communication module. Data transmission consumes electrical energy, causing a voltage drop in the power supply module. Therefore, it is necessary to adjust the operating mode of the communication module. In this embodiment, the target module refers to the communication module in operation.

[0171] When the target module is a communication module, the system controls the communication module to send data at target intervals. The target interval can be any suitable value, for example, 100 milliseconds.

[0172] In this embodiment, by controlling the communication module to send data at target intervals, the voltage of the power supply module will recover during the target interval when no data is sent, thereby ensuring that the voltage of the power supply module is greater than the restart voltage, thus ensuring that the system will not restart and improving the user experience.

[0173] In one embodiment, the reason why the communication module consumes a lot of power when sending data is that the current communication protocol of the communication module has a slow data transmission rate. To address this, the system switches the current communication protocol of the communication module to the target communication protocol. For example, the system can eliminate communication protocols with slow transmission rates from multiple communication protocols, and use the remaining communication protocols as the target communication protocol. Communication protocols with transmission rates lower than a preset rate are considered slow-transmission protocols.

[0174] Furthermore, the network environment in which the system operates may experience network fluctuations. If the network signal is currently weak, the communication module may take too long to transmit data, increasing the communication time and causing the communication module to operate at high power consumption for an extended period, leading to a drop in the power supply module's voltage. Additionally, a weak network signal may prevent the communication module from receiving response messages from the network. The communication module will then retransmit data to the network to obtain a response, resulting in prolonged high power consumption and further reducing the power supply module's voltage. To address this, the system controls the communication module to stop transmitting data to reduce its power consumption and thus increase the power supply module's voltage.

[0175] In addition, after the system switches the current communication protocol of the communication module to the target communication protocol, it controls the communication module to send data at target intervals under the target communication protocol, so that the voltage of the power supply module is greater than the restart voltage.

[0176] In addition, the system includes a viewing function with a corresponding activation password. When an external device connects to the system, it enters an initial password. The external device then generates a usage request for the viewing function based on this initial password and sends the request to the system. The system parses the usage request to obtain the initial password. If the initial password matches the activation password, the system executes the viewing function. The viewing function involves plotting the voltage of the power supply module as a curve and sending the curve to the external device for display, allowing users to observe voltage changes in the power supply module. The curve can also include multiple specific time points, such as the time when the communication module starts and stops sending data. This viewing function allows users to easily monitor voltage changes in the power supply module and the data transmission status of the communication module. By observing these voltage changes and data transmission status, users can perform self-testing for faults in both the power supply and communication modules, improving the user experience.

[0177] In this embodiment, the system ensures that the voltage of the power supply module is greater than the restart voltage by switching the communication protocol of the communication module or controlling the communication module to stop sending data.

[0178] Reference Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the control method disclosed herein, based on Figure 3 In the embodiment shown, step S301 includes:

[0179] Step S401: Obtain the operating mode of the communication module.

[0180] Step S402: According to the operating mode, control the communication module to send data at target intervals.

[0181] In this embodiment, the communication module is equipped with multiple operating modes, including at least a network mode and a data transmission mode.

[0182] Networked mode refers to the connection between the communication module and the network. In networked mode, the system first scans the network channels to attempt to connect to the network access point; once the access point connection is successful, an authentication request is sent to authenticate the system's identity; once authentication is successful, the system then associates with the network gateway device through the communication module. During the association process, the system sends network data packets to the gateway device for a handshake.

[0183] Data transmission mode refers to the system interacting with external devices through the communication module.

[0184] In both network mode and data transmission mode, the communication module needs to send data, which causes a voltage drop in the power supply module. However, the adjustment strategy for the communication module's operation differs depending on the operating mode. Therefore, the system needs to control the communication module to send data at target intervals based on its operating mode. An example of controlling the communication module to send data at target intervals based on its operating mode is as follows:

[0185] In one example, when the communication module operates in networking mode, the system repeatedly sends network data packets to ensure a successful network connection, resulting in high power consumption and a drop in the power supply module's voltage. Therefore, the system controls the communication module to send network data packets at target intervals. Sending network data packets at target intervals interrupts the continuous retransmission of network data packets, reducing power consumption. Sending network data packets at target intervals allows the communication module to attempt multiple network connection attempts, ensuring a successful network connection for the system.

[0186] In another example, when the communication module operates in data transmission mode, the system determines the capacity of the data packet to be sent. If the capacity is greater than the preset capacity, it can be determined that the data packet sent by the communication module is a large-capacity data packet. Sending large-capacity data packets takes a long time, resulting in higher power consumption and a voltage drop in the power supply module. Therefore, the system divides the large-capacity data packet into multiple sub-data packets. The system controls the communication module to send one or more sub-data packets at target intervals, and the total capacity of each sub-data packet sent is less than the capacity of the large-capacity data packet. It can be understood that by dividing the large-capacity data packet into multiple sub-data packets and sending one or more sub-data packets at target intervals, the system ensures that the communication module's data transmission time is not too long in a single session, thus preventing excessive power consumption. The power supply module's voltage rises during the target interval when the communication module is not sending data packets, and the power consumption of the communication module is low during a single data packet transmission. The voltage drop in the power supply module is small or even non-existent, ensuring that the power supply module's voltage is greater than the restart voltage, thereby preventing the system from restarting and ensuring stable system operation.

[0187] In one embodiment, when the operating mode instructs the communication module to connect to the network, the system has multiple ways to control the communication module to send network data packets at target intervals. The specific methods are as follows:

[0188] In one example, the system controls the communication module to send a target number of network data packets at target intervals, where the target number is lower than the set number of network data packets sent by the communication module for network connection. For instance, normally the communication module sends four network data packets to connect to the network. If the system controls the communication module to send network data packets at target intervals, the communication module will send only two network data packets per transmission instead of four. Reducing the number of network data packets sent per transmission lowers the communication module's power consumption. The reduced power requirement of the communication module prevents a drop in the voltage of the power supply module, ensuring that the voltage of the power supply module is greater than the restart voltage and preventing the system from restarting.

[0189] In another example, the system controls the communication module to send one or more network data packets within a first data transmission duration at target intervals. The first data transmission duration is set based on a network connection limit, which refers to the maximum duration the system can stay connected to the network. For example, if the system needs to establish a network connection within 1000 milliseconds, then 1000 milliseconds is the network connection limit. A specific example of setting the first data transmission duration based on the network connection limit is as follows:

[0190] In one sub-example, the duration of the first data transmission is set to be less than the network upper limit duration. For instance, the network upper limit duration is 1000 milliseconds, and the communication module can send 8 network data packets within 1000 milliseconds. Since the first data transmission duration is less than 1000 milliseconds, the number of network data packets sent by the communication module within the first data transmission duration is less than the number sent within the network upper limit duration. This reduces the number of data packets sent by the communication module at a time, resulting in a smaller voltage drop in the power supply module before its subsequent rise, thus ensuring that the power supply module's voltage is greater than the restart voltage. Furthermore, the first data transmission duration cannot be set too small; it must ensure that the communication module sends at least one network data packet within the first data transmission duration, meaning that the communication module performs at least one handshake with the network each time it sends a network data packet. In this sub-example, the duration of the first data transmission can vary each time, but each duration is less than the network upper limit duration.

[0191] In another sub-example, the current voltage of the power supply module is obtained, and a first difference between the current voltage and the restart voltage is determined. Then, a first data transmission duration is determined based on the first difference and the network connection limit duration. For example, an initial data transmission duration is first set based on the network connection limit duration, which is less than the network connection limit duration. Then, the initial data transmission duration is corrected using the first difference to obtain the first data transmission duration. For instance, if the system has a voltage modification threshold, when the first difference is less than the modification threshold, the current voltage is closer to the restart voltage, increasing the probability of the power supply module restarting. In this case, the system needs to reduce the initial data transmission duration to shorten the duration of continuous data transmission by the communication module, thereby reducing the power consumption of the communication module and ensuring that the voltage of the power supply module remains constant or increases. When the first difference is greater than or equal to the modification threshold, the current voltage is slightly greater than the restart voltage, so the probability of the power supply module restarting does not increase, and there is no need to reduce the power consumption of the communication module by decreasing the initial data transmission duration.

[0192] After determining the duration of the first data transmission, the system sets a target number of times the communication module will send data. For example, if the communication module sends data in four batches, these four batches constitute the target number. The duration between two consecutive data transmissions is the target interval. The duration of each data transmission is the duration of the first data transmission. The system controls the communication module to send data only after the target interval. Furthermore, the system sets a maximum tolerance duration for successful network connection. This maximum tolerance duration is the upper limit of tolerance. Therefore, the total duration obtained by multiplying the sum of the target interval and the duration of the first data transmission by the target number of transmissions is less than the maximum tolerance duration. For example, if the target number of transmissions is 10, the upper limit of tolerance is 3000 milliseconds, the target interval is 200 milliseconds, the duration of the first data transmission is 50 milliseconds, and the total duration of the communication module stopping and transmitting data once is 200 milliseconds + 50 milliseconds = 250 milliseconds, the product of the total duration and the target number of transmissions is 2500 milliseconds. 2500 milliseconds is less than the upper limit of tolerance of 3000 milliseconds.

[0193] It should be noted that when the system determines the operating mode and instructs the communication module to connect to the network, the device can directly control the communication module to send network data packets at target intervals. However, sending a network data packet to the network once may complete the connection between the communication module and the network. In this case, sending network data packets again at target intervals would waste the communication module's resources.

[0194] In response, when the operating mode instructs the communication module to connect to the network, the system obtains the target parameters corresponding to this connection. These parameters include the number of network connection failures and the signal quality parameters of the target network to which the communication module connects. If the target parameters meet the set conditions, the system then controls the communication module to send network data packets at target intervals. Meeting these conditions includes at least one of the following: the number of network connection failures exceeding a preset number or the signal quality parameters falling below a preset threshold. The specific explanation for controlling the communication module to send network data packets at target intervals when the number of network connection failures exceeds the preset number or the signal quality parameters fall below the preset threshold is as follows:

[0195] If the number of network connection failures exceeds the preset number, the communication module will continuously and repeatedly send network data packets. Continuous and repeated sending of network data packets will cause the power consumption of the communication module to be high, which may reduce the voltage of the power supply module. In this case, the communication module is controlled to send network data packets at target intervals to interrupt the continuous and repeated sending of network data packets, thereby reducing the power consumption of the communication module and making the voltage of the power supply module higher than the restart voltage, thus preventing the power supply module from restarting.

[0196] It should be noted that during the phase when the communication module sends network data packets at target intervals, the system still records the number of network connection failures. If the currently recorded number of network connection failures reaches the upper limit, it can be determined that a network problem is causing the communication module to fail to connect to the network. The system then controls the communication module to stop sending network data packets and outputs a prompt message. This prompt message is used to instruct the user to check the network device to determine if the network device is malfunctioning. The upper limit is greater than the preset limit.

[0197] If the signal quality parameters are lower than the preset threshold, it can be determined that the network quality of the target network is poor. The communication module needs to connect to the target network multiple times before it can successfully connect. In this case, the communication module is controlled to send network data packets at target intervals to reduce the power consumption of the communication module and make the voltage of the power supply module greater than the restart voltage to avoid restarting the power supply module.

[0198] Furthermore, if the communication module is constantly connected to the network, functions that do not require a network connection will also malfunction, degrading the user experience. To address this, the device obtains the first interval between the time the communication module begins sending data and the current time. If this first interval is greater than or equal to the tolerable upper limit, the device controls the communication module to stop sending data, allowing functions that do not require a network connection to operate normally, thus improving the user experience. The tolerable upper limit is the maximum tolerable duration mentioned above, as detailed in the explanation above, and will not be repeated here.

[0199] It should be noted that when the operating mode instructs the communication module to connect to the network, the system determines whether the system has successfully connected to the network while sending network data packets after each target time interval. If the system has successfully connected to the network, the system controls the communication module to stop sending network data packets and no longer adjusts the operating mode of the communication module, that is, it no longer sends network data packets at each target time interval.

[0200] Reference Figure 5 , Figure 5 This is a flowchart illustrating the fourth embodiment of the control method disclosed herein, based on Figures 2 to 4 In any of the embodiments shown, step S201 includes:

[0201] Step S501: Determine the second data transmission duration and the target interval duration of the communication module.

[0202] Step S502: For each target interval duration, the duration for which the control communication module sends data is less than or equal to the duration for which the second data is continuously sent.

[0203] In this embodiment, the system controls the communication module to send data at each target interval. The target interval and the duration of the second data transmission for each data transmission by the communication module need to be determined by the system.

[0204] For example, the duration of continuous second data transmission varies depending on the operating mode. For instance, if the operating mode instructs the communication module to connect to the network, the system obtains the maximum network connection time corresponding to this time and sets the duration of continuous second data transmission to be less than this maximum time. Conversely, if the operating mode instructs the communication module to send a large data packet, the system obtains the total time required for the communication module to complete sending the large data packet and sets the duration of continuous second data transmission to be less than this total time. For example, if the total time is 20 seconds, the duration of continuous second data transmission can be 1 second.

[0205] When the system needs to determine the target interval duration, it obtains the time required for the power supply module to recover from its lower voltage limit to its upper voltage limit. This time is an empirical value and is defined as the empirical duration. The system sets the target interval duration to be greater than the empirical duration to ensure that the power supply module's voltage recovers to a higher voltage within the target interval during which no data is transmitted, thus preventing the power supply module from restarting. For example, if testing shows that the time required for the power supply module to increase from its lower voltage limit to its upper voltage limit is 3000 milliseconds, then the target interval duration is set to 6000 milliseconds.

[0206] In this embodiment, the system determines the second data transmission duration and the target interval duration of the communication module, and controls the duration of the communication module's data transmission to be less than or equal to the second data transmission duration at each target interval, ensuring that the system will not restart while ensuring that the communication module completes data transmission in advance.

[0207] Reference Figure 6 , Figure 6 This is the fifth embodiment of the control method disclosed herein. Based on the fourth embodiment, the determination of the second data transmission duration in step S501, which involves the communication module transmitting data, includes:

[0208] Step S601: Obtain the voltage drop time of the power supply module from the initial voltage to the restart voltage. The initial voltage is used to indicate the voltage of the power supply module when the communication module is not running.

[0209] In this embodiment, the power supply module provides sufficient power to the communication module, ensuring stable system operation. If the power supply module voltage drops to the restart voltage, the system will restart. Based on this, the system sets a second data transmission duration based on the interval between its normal operation and restart.

[0210] Specifically, the system acquires the voltage drop duration of the power supply module from the initial voltage to the restart voltage. The initial voltage refers to the voltage of the power supply module when the communication module is not running, and the restart voltage refers to the voltage of the power supply module when the system transitions from the running state to the restart state. The voltage drop duration can be acquired in several ways; see the following example for details:

[0211] In one example, the voltage drop duration can be obtained by testing the voltage drop of the power supply module in the system. The obtained drop duration is stored in the system, and the system retrieves the stored drop duration as the voltage drop duration.

[0212] In another example, the system first determines the protection voltage using the restart voltage. The protection voltage refers to the voltage of the power supply module when the system is at the critical restart point, while the restart voltage refers to the voltage of the power supply module when the system transitions from the running state to the restart state. Therefore, the protection voltage is greater than the restart voltage. After obtaining the protection voltage, the system acquires the voltage drop rate corresponding to the power supply module and determines the second difference between the initial voltage and the protection voltage. The system uses the ratio between the second difference and the voltage drop rate as the voltage drop duration. There are several ways to obtain the voltage drop rate. In one sub-example, the voltage drop rate is an empirical value obtained by testing the voltage drop rate of the power supply module. This empirical value is stored in the system, and the system extracts it from the storage area as the voltage drop rate. In another sub-example, the voltage drop rate can be acquired in real time. Specifically, the system acquires the first voltage V1 of the power supply module from the last acquisition and the first acquisition time point t1. The system then acquires the second voltage V2 of the power supply module currently being acquired and the second acquisition time point t2. Therefore, the voltage drop rate = (V1-V2) / (t2-t1).

[0213] Step S602: Determine the second data transmission duration of the communication module based on the voltage drop duration, wherein the second data transmission duration is less than the voltage drop duration.

[0214] The voltage drop duration is a theoretical value. In reality, the time it takes for the initial voltage of the power supply module to drop to the restart voltage may be shorter than the voltage drop duration. Therefore, one way to set the second data continuous transmission duration is to set it to be less than the voltage drop duration. Another way to set the second data continuous transmission duration is to multiply the voltage drop duration by a coefficient less than 1 to obtain the second data continuous transmission duration. For example, the coefficient is 0.25, which means taking one-quarter of the voltage drop duration as the second data continuous transmission duration.

[0215] In this embodiment, the device obtains the voltage drop duration of the power supply module from the initial voltage drop to the restart voltage, and then accurately determines the second data transmission duration of the communication module by using the voltage drop duration.

[0216] Reference Figure 7 , Figure 7 In the sixth embodiment of the control method disclosed herein, based on the fourth or fifth embodiment, determining the target interval duration in step S501 includes:

[0217] Step S701: Obtain the voltage recovery time of the power supply module from the target voltage to the initial voltage. The initial voltage is used to indicate the voltage of the power supply module when the communication module is not running.

[0218] In this embodiment, the data transmission interval of the communication module needs to be set by the voltage recovery time of the power supply module. The interval is the target interval mentioned above, and the voltage recovery time refers to the time it takes for the target voltage to recover to the initial voltage. The target voltage is either the restart voltage or the protection voltage. There are several ways to determine the voltage recovery time; see the following example for details:

[0219] In one example, the voltage recovery time is a test value of the power supply module recovering from the target voltage to the initial voltage, which is stored in the system. The system retrieves the stored test value from the storage area as the voltage recovery time.

[0220] In another example, the system obtains the voltage recovery rate of the power supply module and determines a third difference between the initial voltage and the target voltage. Based on the ratio between the third difference and the voltage recovery rate, the voltage recovery time is determined.

[0221] The voltage recovery rate can be obtained through the following example:

[0222] In one example, the voltage recovery rate can be determined by the voltage drop rate, for example, by multiplying the voltage drop rate by a factor. This factor is obtained as follows:

[0223] Under standard operating conditions, the voltage drop rate and voltage recovery rate of the power supply module are tested, and the ratio of the voltage recovery rate to the voltage drop rate is set as a multiple in the device.

[0224] In another example, the voltage recovery rate can be determined based on the voltage recovery process of the power supply module. Specifically, the system acquires the third and fourth voltages of the power supply module during the voltage recovery process, with the acquisition time of the fourth voltage being later than that of the third voltage. The system determines the voltage recovery rate of the power supply module based on the acquisition time intervals of the third voltage, the fourth voltage, and the third voltage and the fourth voltage. For example, the system stores the voltages of the power supply module after the target module has previously adjusted its operating mode. Each voltage has a corresponding acquisition time point. Based on each acquisition time point, it can be determined that the voltage of the power supply module has recovered from time point x to time point y. Then, two voltages are randomly acquired from time point x to time point y. The earlier acquisition time point of the two voltages is defined as the third voltage V3, and the other voltage is defined as the fourth voltage V4. The acquisition time point of the third voltage is t3, and the acquisition time point of the fourth voltage is t4. Then, the voltage recovery rate = (V4-V3) / (t4-t3).

[0225] Step S702: Determine the target interval duration based on the voltage recovery time, where the target interval duration is longer than the voltage recovery time.

[0226] After obtaining the voltage recovery time, the target interval time can be determined based on the voltage recovery time. Specifically, the voltage recovery time is a theoretical value, and the actual recovery time of the power supply module voltage may be longer than the voltage recovery time. Therefore, the target interval time is set to be longer than the voltage recovery time.

[0227] In this embodiment, the system can accurately determine the target interval duration by measuring the time it takes for the target voltage of the power supply module to recover to the initial voltage.
