[0002] In the power system, line leakage is a common and important issue. To ensure the safe operation of power facilities and reduce energy waste and potential safety hazards caused by leakage, people usually set up leakage prevention monitoring devices to monitor line leakage. These devices can monitor the leakage situation of the line in real time. Once a leakage phenomenon is detected, they can immediately issue an alarm and take corresponding measures to avoid accidents.

[0046] The following will, in conjunction with the accompanying drawings, elaborate in detail on the anti-leakage monitoring device, method, and equipment with low-power design provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0047] The application scenario of the embodiments of the present application is to reduce the power consumption during the anti-leakage monitoring process, and the execution entity of the embodiments of the present application is an anti-leakage monitoring device with low-power design.

[0048] Figure 1 It is a schematic flowchart of a method for anti-leakage monitoring with low-power design provided by the embodiments of the present application. As Figure 1 shown, the method includes:

[0049] S101. The voltage monitoring unit determines the voltage operating state of the device under test based on the voltage data obtained in real time. When it is determined that the device under test is in an abnormal voltage state, it determines the cause of the abnormal state of the device under test based on the voltage data, determines the voltage risk level based on the voltage data and the cause of the abnormal state, generates a voltage abnormal signal based on the voltage risk level, and sends it to the main control unit to trigger the main control unit to switch from the sleep state to the working state.

[0050] Among them, the voltage monitoring unit is a device used to monitor the voltage situation of the power system or equipment in real time. It can accurately measure and display voltage data, and at the same time has certain data processing and communication capabilities. It can also transmit voltage information to the main control unit for further analysis and processing. Voltage data refers to the voltage values and their related information collected and recorded by the voltage monitoring unit. These data usually include parameters such as the amplitude, frequency, and phase of the voltage, which are important bases for evaluating the operating status of the power system and conducting fault diagnosis. The voltage operating state refers to the actual voltage situation of the power system or equipment during operation. Under normal circumstances, the voltage should fluctuate within a certain range to ensure the stability of the power system and the safe operation of electrical equipment. The voltage abnormal state refers to the situation where the voltage of the power system or equipment deviates from the normal range during operation, specifically including abnormal situations such as too high voltage, too low voltage, and excessive voltage fluctuations. The cause of the abnormal state refers to the root cause of the voltage abnormal situation. The voltage risk level refers to the level divided according to the degree of harm that the voltage abnormal state may cause to the power system or equipment. Usually, the voltage risk level will be comprehensively considered and divided according to factors such as the severity, duration of the voltage abnormality, and possible consequences. The voltage abnormal signal refers to the alarm or warning signal sent by the voltage monitoring unit when it detects the voltage abnormal state. These signals usually include indications of the voltage abnormal situation, as well as possible fault information or recommended countermeasures, etc. The main control unit refers to the core part of the voltage monitoring unit responsible for data processing, communication, and control. It usually has powerful computing capabilities and rich interface resources, can receive the voltage abnormal signal of the voltage monitoring unit, and issue corresponding control instructions according to the voltage abnormal signal. The sleep state refers to the low-power state of the voltage monitoring unit when it is not performing voltage monitoring. In this state, the voltage monitoring unit will turn off or reduce the power consumption of some circuits to extend the service life of the device and reduce energy consumption. The working state refers to the state of the voltage monitoring unit when it is performing voltage monitoring. In this state, the voltage monitoring unit will collect and record voltage data in real time, perform data processing and analysis, and transmit the results to the upper computer or other monitoring systems for further processing and display.

[0051] In one embodiment, a suitable voltage sensor is selected and connected to the circuit of the device under test to ensure that its voltage value can be accurately collected. A reasonable acquisition frequency is set, which should not only be able to promptly reflect voltage changes but also not be too frequent to cause resource waste and data redundancy. For example, for some devices with relatively stable voltages, collecting several times per second may be sufficient; while for devices with large voltage fluctuations, dozens of times or even higher frequencies of collection may be required. Then, the voltage information of the device under test is obtained through the voltage monitoring unit. Then, a normal voltage range is set. Specifically, according to materials such as the specification of the device under test, the voltage range in which it normally operates is determined. For example, the normal operating voltage of a certain device is 220V ± 10%, that is, 198V - 242V. It is judged whether the acquired voltage data is within the normal range. If it is not within this range, it is determined to be in an abnormal voltage state.

[0052] After it is determined to be in an abnormal state, the specific situation of the voltage data is further analyzed to determine the cause of the voltage abnormality. For example, if the voltage continuously remains below the normal range and the downward trend is obvious, it may be due to insufficient power supply; if there are large voltage fluctuations, there may be problems such as poor contact in the circuit. Specifically, corresponding rules for judging the cause of the abnormal state can be established according to different voltage data characteristics. For example, if the voltage data crosses the upper and lower limits of the normal range multiple times within a short period and the change amplitude is large, it can be judged that there is an intermittent short circuit or open circuit fault in the circuit. Further, a standard for dividing the voltage risk level is formulated in advance, usually based on factors such as the degree of deviation of the voltage from the normal range, the duration of the abnormality, and the degree of damage that may be caused to the device. For example, it can be divided into low risk (the voltage slightly deviates from the normal range and is abnormal for a short time), medium risk (the voltage significantly deviates from the normal range or the abnormality lasts for a period of time), high risk (the voltage seriously deviates from the normal range and is abnormal for a long time, which may cause device damage) levels. Then, based on the previously determined voltage data and the cause of the abnormal state, according to the risk level division standard, the current voltage risk level is determined through a certain logical algorithm. For example, if the voltage is 30% lower than the normal range and the duration exceeds 5 minutes, and the cause of the abnormality is serious damage to the power supply line, it can be determined to be a high risk level.

[0053] After the voltage risk level is determined, according to the corresponding protocol and format, a signal representing the voltage abnormality is generated. The signal can be in the form of digital coding, such as using specific binary codes to represent different risk levels and abnormal situations. The voltage monitoring unit sends the generated voltage abnormality signal to the main control unit through a suitable communication interface. After receiving the signal, the hardware circuit of the main control unit should have a mechanism to switch from the sleep state to the working state. Usually, it is triggered by an interrupt signal or the like, so that the main control unit can promptly respond to the voltage abnormality and perform subsequent processing, such as recording abnormal information and taking protection measures.

[0054] Optionally, the voltage data includes voltage values, and the voltage monitoring unit determines the voltage operating state of the device under test based on the voltage data obtained in real time, including:

[0055] When it is satisfied that the voltage value is continuously monitored to be greater than the preset threshold within the first preset time period, it is determined that the voltage operating state is an abnormal state;

[0056] When it is not satisfied that the voltage value is continuously monitored to be greater than the preset threshold within the first preset time period, determine the number of times that the voltage fluctuation value exceeds the preset fluctuation value within the second preset time period. When the number of times is greater than or equal to the preset number of times, determine that the voltage operating state is an abnormal state; otherwise, determine that the voltage operating state is a normal state.

[0057] Among them, the first preset time period refers to the minimum duration required to determine that the voltage value exceeds the preset range and can reach voltage abnormality. The preset voltage threshold is the highest limit of the voltage value set in advance, which is used to judge whether the voltage is within the normal range. The second preset time period refers to the preset duration for monitoring the voltage fluctuation situation. The voltage fluctuation value refers to the degree to which the voltage deviates from a certain reference value (such as the average value or the rated voltage) within a certain period of time. For example, the rated voltage of a certain device is 220V. Within 10 minutes, the highest voltage collected reaches 225V, and the lowest reaches 218V. Then the voltage fluctuation value is determined by calculating these values that deviate from the rated voltage of 220V. It can be measured by the maximum fluctuation value. In this example, the maximum fluctuation values are +5V and -2V. The preset fluctuation value is a preset allowable voltage fluctuation range. For example, for precision instruments that require high voltage stability, the preset fluctuation value may be set to ±1V. If the actual voltage fluctuation value exceeds this range, it means that the voltage fluctuation is abnormal and may affect the accuracy of the instrument. The preset number of times refers to the number of times that the voltage fluctuation value exceeds the preset fluctuation value.

[0058] In one embodiment, within the first preset time period T1, the voltage value is continuously monitored. If at any moment within the T1 time period, the voltage value is greater than the preset voltage threshold, it is determined that the voltage operating state is an abnormal state. If the voltage value greater than the preset voltage threshold is not continuously monitored within the T1 time period, then enter the next step of judgment: judge the number of voltage fluctuations within the second preset time period. Specifically, within the second preset time period T2, continue to monitor the voltage value, calculate the voltage fluctuation value of each sampling point (or time period). If the voltage fluctuation value exceeds the preset fluctuation value, the counter is incremented by 1. At the end of the T2 time period, check whether the value of the counter is greater than or equal to the preset number of times N. If the counter value is greater than or equal to N, it is determined that the voltage operating state is an abnormal state. If the counter value is less than N, it is determined that the voltage operating state is a normal state.

[0059] Figure 2It is a schematic flowchart of a method for determining the cause of the abnormal state of the device under test based on the voltage data provided by an embodiment of the present application. As Figure 2 shown, the method includes:

[0060] S1011. When it is determined that the voltage operating state is an abnormal state, obtain the change curve of the voltage abnormal data of the device under test.

[0061] Among them, voltage abnormal data refers to data points or data sets in which the voltage value deviates from the expected range or the fluctuation value exceeds the preset value within a preset period and meets the preset number during the monitoring or recording process. The change curve of voltage abnormal data refers to a curve graph showing the change of voltage abnormal data over time generated based on time points and voltage abnormal data.

[0062] In one embodiment, during the monitoring process, the collected voltage data is stored in a cache. When voltage anomalies are detected, mark these abnormal data points, store the abnormal data points separately in a specific file or database, and attach timestamps and other relevant information. Set appropriate X-axis (time) and Y-axis (voltage value) ranges, as well as parameters such as the color and line type of the curve, and substitute the abnormal data values and timestamps to generate a change curve of abnormal data, so as to clearly display the change trend of voltage abnormal data.

[0063] S1012. Obtain the location information of the device under test, and determine other operating devices within a preset range based on the location information.

[0064] Among them, location information refers to the specific positioning or coordinates of an object or device in space. The preset range refers to a certain geographical range or interval set or specified in advance. Other operating devices refer to other devices that are still operating within the preset range in addition to the current device under test.

[0065] In one embodiment, the location data of the device under test, including longitude, latitude (for outdoor positioning) or indoor positioning coordinates, is collected in real time through a positioning module built in the device under test. According to actual needs, set a preset range centered on the location of the device under test with a specific radius or boundary. Use the device database or cloud platform in the data collection system to query other operating devices within the preset range. Specifically, these devices may have similar positioning modules and have uploaded their location data to the cloud platform. Match the queried devices with the location information of the device under test to filter out the devices located within the preset range.

[0066] S1013. Based on the cloud platform, obtain the voltage change curves of the other operating devices during the same time period, and determine whether the change curve of the voltage abnormal data of the device under test meets the preset similarity with the voltage change curves of the other operating devices.

[0067] Among them, the cloud platform is a service platform based on hardware resources and software resources used to provide computing, networking, and storage capabilities. In this embodiment, the cloud platform stores the operating parameters of all devices. Users can directly obtain the required resources from the cloud by sending requests over the network. The voltage change curve is a graph showing how the voltage of other devices changes over time or under certain conditions, and is usually used to study the stability and fluctuations of voltage. The preset similarity is a similarity threshold or criterion set in advance when performing comparison or matching tasks, used to determine whether two objects are similar enough.

[0068] In one embodiment, through the cloud platform, voltage data of the device under test and other operating devices in the same time period are obtained. The data may include information such as voltage values and timestamps. Based on the voltage values and timestamps, a voltage change curve is plotted. An appropriate similarity calculation method, such as cosine similarity, Euclidean distance, dynamic time warping, etc., is used to calculate the similarity between the voltage anomaly data change curve of the device under test and the voltage change curves of other operating devices. Among them, the choice of the similarity calculation method should be based on data characteristics and application scenarios and is not specifically limited. The calculated similarity is compared with the preset similarity threshold. If the similarity is greater than or equal to the preset similarity threshold, it is considered that the voltage anomaly data change curve of the device under test is similar to the voltage change curves of other operating devices, and there may be some association or common cause. If the similarity is less than the preset similarity threshold, it is considered that the voltage anomaly data change curve of the device under test is not similar to the voltage change curves of other operating devices, and the reasons of the device itself need to be further analyzed.

[0069] S1014. If the number of operating devices that meet the preset similarity meets the preset percentage, determine that the cause of the abnormal state of the device under test is grid fluctuation; if not, determine that the cause of the abnormal state of the device under test is device failure.

[0070] Among them, the preset percentage is a pre-set proportional value used to determine whether there is some association or common cause between the voltage anomaly of the current device and other devices. Grid fluctuation refers to abnormal changes in parameters such as voltage, current, and frequency in the power grid. Device failure refers to the situation where a device exhibits anomalies or malfunctions during operation, resulting in a decline in device performance or the inability to complete normal work.

[0071] In one embodiment, all operating devices within a preset range are traversed, the similarity between them and the current device under test is calculated, and compared with the preset similarity. If the similarity is greater than or equal to the preset similarity, the count of the number of devices that meet the conditions is incremented by 1. For example, there are a total of n operating devices. After comparison, the number of devices that meet the preset similarity is m. Calculate the percentage of the number of devices that meet the preset similarity in the total number of devices, that is Compare this percentage with a preset percentage. If it is greater than or equal to the preset percentage, then it can be determined that the cause of the abnormal state of the device under test is grid fluctuation. Since the voltage change conditions of most devices are similar, it is very likely caused by external grid factors. Conversely, if it is less than the preset percentage, it is determined that the cause of the abnormal state of the device under test is a device failure. Since only a few devices are abnormal, it is a problem with the device itself.

[0072] Optionally, determining the voltage risk level based on the voltage data and the cause of the abnormal state includes:

[0073] When it is continuously monitored within the first preset time period that the voltage value is greater than the preset threshold, and the cause of the abnormal state of the device under test is a device failure, determine that the voltage risk level is the first risk level;

[0074] When the number of times that the voltage fluctuation value exceeds the preset fluctuation value within the second preset time period is greater than or equal to the preset number of times, and the cause of the abnormal state of the device under test is a device failure, determine that the voltage risk level is the second risk level;

[0075] When it is continuously monitored within the first preset time period that the voltage value is greater than the preset threshold, and the cause of the abnormal state of the device under test is grid fluctuation, determine that the voltage risk level is the third risk level;

[0076] When the number of times that the voltage fluctuation value exceeds the preset fluctuation value within the second preset time period is greater than or equal to the preset number of times, and the cause of the abnormal state of the device under test is grid fluctuation, determine that the voltage risk level is the fourth risk level; where the urgency of the first risk level is greater than the second risk level, which is greater than the third risk level, which is greater than the fourth risk level.

[0077] Among them, the first risk level, the second risk level, the third risk level, and the fourth risk level respectively refer to the severity of the current voltage abnormality, and the urgency of the first risk level is greater than the second risk level, which is greater than the third risk level, which is greater than the fourth risk level.

[0078] In one embodiment, there are two situations for judging voltage anomalies. The emergency level corresponding to the voltage anomaly caused by continuously monitoring that the voltage value is greater than the preset threshold within the first preset period is higher than that corresponding to the voltage anomaly caused by the number of fluctuations of the voltage exceeding the preset fluctuation value being greater than or equal to the preset number within the second preset period. At the same time, there are also two reasons for voltage anomalies. The emergency level corresponding to the voltage anomaly caused by the device's own failure is higher than that corresponding to the voltage anomaly caused by grid fluctuations. Therefore, in the embodiment of the present application, when the data of the voltage anomaly shows that the voltage value is continuously monitored to be greater than the preset threshold within the first preset period and the cause of the voltage anomaly is a device failure, it corresponds to the highest risk level, the first risk level. When the data of the voltage anomaly shows that the number of fluctuations of the voltage exceeds the preset fluctuation value within the second preset period and the cause of the abnormal state is grid fluctuations, it corresponds to the lowest risk level, the fourth risk level. Considering that when the voltage anomaly is caused by the device itself, it has a greater impact on the voltage risk of the fan. Therefore, when the voltage data shows that the number of fluctuations of the voltage exceeds the preset fluctuation value within the second preset period and the cause of the abnormal state is a device failure, it corresponds to the second risk level; when the voltage data shows that the voltage value is continuously monitored to be greater than the preset threshold within the first preset period and the cause of the abnormal state is grid fluctuations, it corresponds to the third risk level.

[0079] Optionally, the voltage anomaly signal includes: an emergency signal, a warning signal, and a prompt signal. Generating a voltage anomaly signal based on the voltage risk level and sending it to the main control unit includes:

[0080] In the case of determining that the voltage risk level is the first risk level, generating an emergency signal and immediately sending it to the main control unit;

[0081] In the case of determining that the voltage risk level is the second risk level, generating a warning signal and sending it to the main control unit within a preset period;

[0082] In the case of determining that the voltage risk level is the third risk level, generating a prompt signal and sending it to the main control unit when the device under test is detected to be in a voltage abnormal state again.

[0083] Among them, emergency signals are signals issued when a very serious situation occurs that may immediately cause major harm or losses. It indicates that immediate action is needed to avoid or mitigate catastrophic consequences. Early warning signals are signals that inform in advance that dangerous or abnormal situations may occur. It means that the situation has not yet reached an emergency state, but if no attention is paid or measures are taken, it is likely to develop into an emergency. Prompt signals mainly provide some information to inform users or operators of the operating status of the equipment and operation prompts. Its purpose is to attract attention, but usually no immediate emergency measures are required.

[0084] In one embodiment, a corresponding signal is generated according to the voltage risk level. If the voltage risk level is the first risk level, an emergency signal is generated; if the voltage risk level is the second risk level, an early warning signal is generated; if the voltage risk level is the third risk level, a prompt signal is generated. The communication module sets the sending priority and sending timing according to the signal type. If it is an emergency signal, it is immediately sent to the main control unit to ensure that the main control unit can respond quickly. If it is a warning signal, it is sent to the main control unit within a preset period of time, allowing the main control unit to have a certain preparation time after receiving the signal. If it is a prompt signal, it is necessary to wait for the device under test to be monitored again as an abnormal voltage state. Specifically, a flag bit can be set to record whether the abnormality occurs again. Each time the voltage state is monitored, this flag bit and the voltage state are checked. When the voltage is abnormal again and the flag bit is true (indicating that it has been in the third risk level before), the prompt signal is sent to the main control unit through a suitable communication method.

[0085] Optionally, the main control unit determines the working mode of the temperature monitoring unit and the communication cycle of the communication unit based on the voltage abnormality signal, including:

[0086] In the case where the voltage abnormality signal is an emergency signal, determining that the working mode of the temperature monitoring unit is an emergency monitoring mode, and the communication cycle of the communication unit is a first cycle;

[0087] In the case where the voltage abnormality signal is a warning signal, determining that the working mode of the temperature monitoring unit is an enhanced monitoring mode, and the communication cycle of the communication unit is a second cycle;

[0088] When the voltage abnormality signal is a prompt signal, it is determined that the working mode of the temperature monitoring unit is the normal monitoring mode, the communication cycle of the communication unit is the third cycle; the first cycle is smaller than the second cycle and smaller than the third cycle.

[0089] Among them, the emergency monitoring mode is enabled when a serious event occurs or is expected to occur. For example, when the device voltage is abnormal and the risk level reaches the highest level, real-time monitoring is required immediately to respond and handle the emergency situation at the fastest speed. The enhanced monitoring mode is enabled under specific circumstances, such as when the device voltage is abnormal and the risk level is high but not at the highest level, or when adverse conditions are predicted. Compared with normal monitoring, this mode encrypts the monitoring frequency to more accurately grasp the dynamics and give early warnings in a timely manner. The normal monitoring mode refers to the monitoring activities carried out according to the regular monitoring plan, which is applicable to the situation where the device voltage risk level is low. In this mode, the monitoring time interval is long, usually carried out according to a fixed cycle.

[0090] In one embodiment, when the voltage abnormal signal is parsed as an emergency signal, the main control unit sets the temperature monitoring unit to enter the emergency monitoring mode, that is, real-time monitoring, through the control line or sending instructions. Specifically, it can directly pull up or pull down the specific control pins of the temperature monitoring unit, or send specific software instructions to make it continuously collect temperature data to achieve real-time monitoring. For the emergency signal situation, the main control unit configures the communication cycle of the communication unit as the first cycle. Specifically, the internal register of the communication unit is set. For example, if the communication unit is based on UART communication, the main control unit can set a higher baud rate by writing a specific value to the baud rate register, so as to achieve a shorter communication cycle (i.e., the first cycle), so as to more quickly send out the real-time temperature data collected by the temperature monitoring unit and other relevant information and timely feedback the device status.

[0091] If the voltage abnormal signal is a warning signal, the main control unit sets the temperature monitoring unit to the enhanced monitoring mode. This mode triggers the temperature monitoring unit to start based on the first preset frequency. The main control unit needs to set a timer or counter and configure its timing or counting parameters according to the value of the first preset frequency. For example, if the first preset frequency is to trigger once every 5 minutes, then set the timer to generate an interrupt or trigger a counting event every 5 minutes. When the event occurs, the main control unit sends instructions or makes the temperature monitoring unit start for temperature collection through the control line. After the collection is completed, the temperature monitoring unit can wait for the next trigger according to its own settings. Correspondingly, when the voltage abnormal signal is a warning signal, the main control unit sets the communication cycle of the communication unit as the second cycle. It is also achieved by adjusting the internal register or configuration parameters of the communication unit. For example, according to the communication rate requirements corresponding to the second cycle, write different values to the baud rate register to set a moderate baud rate, so that the communication cycle becomes longer (longer than the first cycle but shorter than the third cycle) to meet the data transmission requirements in the enhanced monitoring mode.

[0092] When the voltage anomaly signal is a prompt signal, the main control unit configures the temperature monitoring unit to enter the normal monitoring mode. This mode triggers the temperature monitoring unit to start based on the second preset frequency. Similarly, the main control unit needs to set the corresponding timer or counter, and determine the timing or counting parameters according to the value of the second preset frequency. For example, if the second preset frequency is to trigger once every 30 minutes, set the timer or counter according to this frequency so that it triggers the temperature monitoring unit to start collecting temperature data every 30 minutes. After the collection is completed, wait for the next trigger. When the voltage anomaly signal is a prompt signal, the main control unit determines that the communication cycle of the communication unit is the third cycle. This is achieved by adjusting the relevant parameters of the communication unit again. For example, set a relatively low baud rate (by writing an appropriate value to the baud rate register), so as to obtain a longer communication cycle (i.e., the third cycle), because in the normal monitoring mode, the real-time requirement for data transmission is relatively not so high.

[0093] S102. The main control unit determines the working mode of the temperature monitoring unit and the communication cycle of the communication unit based on the voltage anomaly signal.

[0094] Among them, the temperature monitoring unit refers to a device that can monitor the temperature of the device or environment in real time. The working modes of the temperature monitoring unit usually include the real-time monitoring mode and the sleep mode. In the real-time monitoring mode, the temperature monitoring unit continuously collects and processes temperature data and transmits the results to the upper computer or other monitoring systems. In the sleep mode, in order to reduce power consumption, the temperature monitoring unit reduces or turns off the power consumption of some circuits and only wakes up for temperature monitoring when needed. The communication unit is the interface for data transmission between the temperature monitoring unit and other monitoring systems. The communication unit is responsible for transmitting the temperature data and other information collected by the temperature monitoring unit to other monitoring systems for further analysis and processing. The communication cycle refers to the time interval for data transmission between the temperature monitoring unit and the upper computer or other monitoring systems.

[0095] In one embodiment, according to different voltage risk levels, the working modes corresponding to the temperature monitoring unit are preset. For example, in the low voltage risk level, the temperature monitoring unit can be in a low-power intermittent working mode, collecting temperature data every long period (such as 10 minutes); in the medium risk level, the temperature monitoring unit adopts a medium-frequency working mode, collecting data every 3 minutes; in the high risk level, the temperature monitoring unit enters a high-frequency continuous working mode, continuously collecting temperature data. The main control unit receives and analyzes the voltage anomaly signal, which contains relevant information such as the voltage risk level. The main control unit switches its working mode by controlling the power management pin of the temperature monitoring unit or sending a control instruction according to the analyzed voltage risk level. For example, if it is a high risk level, the main control unit can pull up a "continuous working" control pin of the temperature monitoring unit to make it enter the continuous working state.

[0096] The length of the communication cycle depends on the actual application requirements and the system performance requirements. A shorter communication cycle can ensure the real-time and accuracy of data, but may increase the power consumption and communication burden of the system; while a longer communication cycle can reduce the power consumption and communication burden, but may sacrifice the real-time of data. Therefore, it is necessary to make a trade-off according to the actual application scenario when choosing the communication cycle. Therefore, the communication cycle of the communication unit can be set according to the voltage risk level. In the low risk situation, the communication cycle can be longer, such as sending a status report including voltage and temperature to the server once an hour; in the medium risk situation, the communication cycle is shortened to once every 15 minutes; in the high risk situation, the communication cycle can be set to once a minute or even shorter to timely feedback the key status information of the device. Specifically, the main control unit sets the communication cycle by configuring the relevant registers of the communication unit or sending a configuration command. Taking a common device based on UART communication as an example, the main control unit writes different values to the baud rate register inside the communication unit to change the communication rate, thereby achieving different communication cycles. For example, in the low risk state, a lower baud rate is set and the communication cycle becomes longer; in the high risk state, a higher baud rate is set to shorten the communication cycle.

[0097] S103. The temperature monitoring unit and the communication module work and communicate based on the working mode and the communication cycle.

[0098] In one embodiment, the temperature monitoring unit executes different software programs according to the working mode set by the main control unit through the built-in microcontroller. For example, in the intermittent working mode, the software can set a timer interrupt. When the timer reaches the preset intermittent time (such as 10 minutes), an interrupt is triggered, waking up the temperature monitoring unit from the standby state to perform a temperature data acquisition, and then entering the standby state again. In the continuous working mode, the software can be set as a loop to continuously collect temperature data, and an appropriate delay can be set in the middle to control the acquisition frequency. Similarly, in the software of the communication module, a timer or a counter can be used to control the communication cycle. For example, after each communication ends, a timer is started. When the timer count reaches the value set according to the communication cycle, a new communication event is triggered. The software obtains the prepared data from the temperature monitoring unit according to the communication protocol and sends the data out.

[0099] As can be seen from the above, the voltage monitoring unit determines the voltage operation state of the device under test based on the real-time obtained voltage data. When it is determined that the device under test is in an abnormal voltage state, it determines the cause of the abnormal state of the device under test based on the voltage data, determines the voltage risk level based on the voltage data and the cause of the abnormal state, generates a voltage abnormal signal based on the voltage risk level and sends it to the main control unit, triggering the main control unit to switch from the sleep state to the working state; the main control unit determines the working mode of the temperature monitoring unit and the communication cycle of the communication unit based on the voltage abnormal signal; the temperature monitoring unit and the communication module work and communicate based on the working mode and the communication cycle. The above anti-leakage monitoring method with low-power design solves the problem that the anti-leakage monitoring device needs to use electrical energy during operation, and excessive power consumption will lead to an increase in the overall cost and the complexity of installing the monitoring device. This solution can reasonably reduce the power consumption of the anti-leakage monitoring device, thereby improving its energy efficiency and practicability, and reducing the overall usage cost.
