[0001] The present application relates to the technical field of wireless communication and Internet of Things monitoring, and in particular to a signal transmitting device and a working method thereof for power environment monitoring. Background Art

[0002] With the rapid development of the Internet of Things and wireless communication technologies, the demand for remote monitoring of equipment operating status is increasing in scenarios such as substations and communication base stations. In these scenarios, equipment is often deployed in complex electromagnetic environments or under extreme temperature and humidity conditions, requiring real-time monitoring of power environment parameters (such as temperature, humidity, voltage, current, and smoke) while ensuring stable communication links.

[0003] Currently, the power environment monitoring module acquires power environment parameter data and transmits it back to the cloud platform via an antenna. However, the complex power environment affects the antenna's communication stability. For example, drastic fluctuations in temperature and humidity affect the antenna's standing wave ratio, leading to increased bit error rates in the transmission link. In severe cases, this can even cause communication link interruption, directly impacting the real-time performance and reliability of the remote monitoring system.

[0004] Therefore, how to improve the communication stability of transmitting dynamic environment parameter data has become an urgent problem to be solved. Summary of the Invention

[0007] In a feasible design, the power environment parameter data includes temperature data, and the main control module is configured to generate a first instruction according to the power environment parameter data, including: The main control module is configured to determine the target power according to the range to which the temperature data belongs, and the value of the temperature data is negatively correlated with the target power; The main control module is configured to generate a first instruction according to the target power.

[0008] In a feasible design, the power environment parameter data includes voltage data, and the main control module is configured to generate a first instruction according to the power environment parameter data, including: The main control module is configured to determine a target power if the voltage data fluctuates abnormally within a first duration, where the target power is less than a normal power of the signal transmission module, where the normal power is the power used by the signal transmission module during normal operation; The main control module is configured to generate a first instruction according to the target power.

[0009] In a feasible design, the signal processing module is configured to adopt a heartbeat packet mechanism to periodically send data including timestamps and serial numbers to the cloud server, and / or, the signal processing module is configured to adopt an event trigger mechanism to immediately report key data related to the preset event to the cloud server when a preset event is detected.

[0010] In a feasible design, it includes a dual user identity module slot, which has a main card and a secondary card built in the dual user identity module slot, and a signal processing module configured to maintain network connection through the secondary card when the signal quality of the main card meets the switching condition.

[0011] In a feasible design, an electromagnetic shielding module is included, which is used to isolate the electromagnetic interference between the power environment monitoring sensor group, the main control module, the signal transmission module and the sensor data acquisition circuit and the signal transmission module. The sensor data acquisition circuit is used to connect the power environment monitoring sensor group and the main control module.

[0012] In one feasible design, including the heat dissipation module, the main control module is configured as follows: If each temperature data collected during the second duration exceeds the first threshold, a second instruction is sent to the signal processing module, the second instruction being used to obtain a signal packet loss rate within a target period, where the target period is determined based on the second duration; Obtain the signal packet loss rate from the signal processing module; If the signal packet loss rate is greater than a second threshold, the heat dissipation module is activated to cool the device.

For example, reduce the power at high temperatures to prevent the signal transmission module from overheating due to working at a fixed power, causing equipment damage, thereby causing signal interruption.

[0018] Furthermore, by integrating the power environment monitoring sensor group, main control module, signal transmission module, signal processing module, and power module into a single device, this application eliminates the complex wiring required by traditional solutions where sensors and signal transmission modules are deployed separately, significantly reducing costs. Furthermore, this integration shortens the signal transmission path, reduces signal attenuation and interference, and further enhances communication stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Currently, in power environment monitoring systems, elevated ambient temperatures and voltage fluctuations are common. Maintaining a constant power level for antenna equipment in these environments is not only energy-inefficient but also highly likely to cause communication interruptions or equipment failure.

[0023] In order to solve the above problems, Figure 1 As shown, the present application provides a signal transmitting device for power environment monitoring, comprising: A power environment monitoring sensor group, used for collecting power environment parameter data, the power environment monitoring sensor group includes at least one sensor; a main control module, configured to dynamically generate a first instruction according to the power environment parameter data, the first instruction indicating a target power of a transmission signal; A signal transmitting module, used for transmitting signals; a signal processing module configured to generate a target signal according to the power environment parameter data, and control the signal transmitting module to transmit the target signal at a target power according to the first instruction; The power module is used to supply power to the power environment monitoring sensor group, the main control module, the signal transmission module and the signal processing module. That is, the power module is electrically connected to the power environment monitoring sensor group, the main control module, the signal transmission module and the signal processing module respectively; The power environment monitoring sensor group, main control module, signal transmission module, power supply module and signal processing module are integrated in the signal transmission device. The power environment monitoring sensor group is connected to the main control module, the main control module is connected to the signal transmission module, and the signal transmission module is connected to the signal processing module.

[0024] It should be noted that there is a communication connection between the power environment monitoring sensor group and the main control module, a communication connection between the main control module and the signal transmission module, and a communication connection between the signal transmission module and the signal processing module.

[0025] For example, Figure 2 As shown, the power environment monitoring sensor set includes but is not limited to temperature and humidity sensors (such as the SHT30 chip-type digital temperature and humidity sensor), current acquisition sensors, smoke acquisition sensors (such as the MQ-2), and voltage acquisition sensors. These sensors can collect environmental temperature, humidity, and smoke concentration, as well as monitor parameters such as the current and voltage of power equipment.

[0026] Exemplarily, the signal processing module is configured to: The target signal is generated by encoding and modulating the dynamic environment parameter data.

[0027] Exemplarily, the main control module adopts a microcontroller unit (MCU) chip of the STM32 series.

[0028] Exemplarily, the signal transmission module includes: The antenna uses a ceramic substrate as a radiator carrier, covers the target frequency band (for example, the full frequency band of the fourth generation mobile communication technology (4G), i.e., 1700MHz-2600MHz), and adopts an inverted F-shaped structure; Impedance matching network, integrated on ceramic substrate; Balun circuit, integrated on a ceramic substrate; Among them, the signal processing module is connected to the antenna through an impedance matching network and a balun circuit, driving the antenna to transmit signals.

[0029] In the above example, the antenna's inverted-F structure optimizes current distribution, achieving compact size and wide frequency coverage. Using a ceramic substrate as the radiator carrier reduces parasitic capacitance and improves radiation efficiency. Combined with an impedance matching network and balun circuit, the antenna achieves a gain of 5dBi or greater.

[0030] For example, the device is provided with a housing with a protection grade of IP67, heat dissipation fins embedded in the housing, and a surface of the housing is coated with an electromagnetic wave transmitting material. Various components of the device are integrated into the housing.

[0031] In the above example, the housing is completely dustproof and temporarily submersible, ensuring stable operation in dusty, humid, or rainy environments (such as outdoor power base stations), preventing internal circuit failures caused by particulate intrusion or water vapor corrosion. The housing's embedded heat sink fins increase the heat dissipation surface area, accelerating heat dissipation from internal components (such as the main control module and signal transmission module). This prevents performance degradation or hardware degradation caused by heat accumulation in high-temperature environments, indirectly extending the device's lifespan. The electromagnetic wave-transmitting coating on the housing reduces the shielding effect on antenna signals, ensuring effective electromagnetic radiation from the signal transmission module, avoiding signal attenuation or directional distortion caused by the housing material, and maintaining communication quality and coverage. The housing in the above example ensures high reliability, efficient heat dissipation, and stable communication capabilities in complex environments, meeting the comprehensive requirements of industrial scenarios for equipment durability and functional integrity.

[0032] Currently, traditional power environment monitoring equipment (such as temperature and humidity sensors, voltage and current sensors) is deployed separately from communication antennas, resulting in complex and costly wiring. Furthermore, due to the long distance between the sensor group and the communication antenna, communication stability is significantly affected by environmental interference. Furthermore, the complex power environment further impacts the antenna's communication stability.

[0033] This application is based on the function of the power environment monitoring sensor group in the power environment monitoring system to collect power environment parameter data in real time. The main control module provided can dynamically generate a first instruction according to the power environment parameter data, and the signal processing module can dynamically adjust the transmission power of the signal transmission module according to the first instruction, forming a "monitoring-analysis-adjustment" closed loop. The collaborative work of the main control module and the signal processing module, through the linkage of environmental parameters and communication strategies, makes the transmission power adapt to the conditions of the power environment, and can actively offset the impact of environmental interference on the performance of the signal transmission module, avoid the signal transmission module being greatly affected by the environment, causing signal instability or interruption, and improve the stability of communication. For example, reduce the power at high temperatures to prevent the signal transmission module from overheating due to working at a fixed power, causing equipment damage, thereby causing signal interruption.

[0034] Furthermore, by integrating the power environment monitoring sensor group, main control module, signal transmission module, signal processing module, and power module into a single device, this application eliminates the complex wiring required by traditional solutions where sensors and signal transmission modules are deployed separately, significantly reducing costs. Furthermore, this integration shortens the signal transmission path, reduces signal attenuation and interference, and further enhances communication stability.

[0035] Exemplarily, the main control module is configured as follows: Determine whether the power environment parameter data is abnormal; If the power environment parameter data is abnormal, an alarm message is sent to the cloud server through the signal processing module and the signal transmission module. The alarm message is used to indicate that the power environment is abnormal.

[0036] Among them, abnormal power environment parameter data includes but is not limited to: Temperature data exceeding the third threshold, humidity data exceeding the fourth threshold, smoke density data exceeding the fifth threshold, current data exceeding the sixth threshold, voltage data exceeding the seventh threshold, and abnormal voltage fluctuations. The third to seventh thresholds are set based on actual needs and are not limited in this application. Accordingly, alarm information is used to indicate abnormal temperature, abnormal humidity, abnormal smoke density, abnormal current, abnormal voltage, and abnormal voltage fluctuations.

[0037] Further illustratively, abnormal fluctuations in voltage data include the following situations: Voltage sag, for example, a sudden drop to below 90% of the normal voltage. The duration can be set as needed. The normal voltage value refers to the voltage value monitored by the voltage acquisition sensor when the device is operating normally.

[0038] Voltage swell, i.e. a momentary increase in voltage to more than 110% of the normal voltage value.

[0039] Voltage interruption: the voltage is completely interrupted or drops to near zero, and the duration can be set according to requirements.

[0040] Sustained fluctuations: For example, the voltage fluctuates around the normal voltage value more than a preset number of times within the first duration, with the maximum fluctuation being 110% of the normal voltage value and the minimum fluctuation being 90% of the normal voltage value. The first duration is set based on actual needs, for example, 5 minutes.

[0041] Currently, antennas lack the ability to proactively monitor the equipment's operating environment, making fault warnings difficult. This makes them susceptible to interference when the power environment deteriorates. The above example utilizes real-time data collected by a power environment monitoring sensor group, including temperature, voltage, and current. The main control module dynamically analyzes this data to promptly identify abnormalities in the power environment. This allows for the timely identification of sources of electromagnetic interference (such as increased device noise due to high temperatures) or potential faults (such as voltage drops), providing proactive warnings. This allows personnel to quickly arrive at the scene for resolution, ensuring stable communication for the antenna.

[0042] In a feasible design, the power environment parameter data includes temperature data, and the main control module is configured to generate a first instruction according to the power environment parameter data, including: The main control module is configured to determine the target power according to the range to which the temperature data belongs, and the value of the temperature data is negatively correlated with the target power; The main control module is configured to generate a first instruction according to the target power.

[0043] For example, the main control module is preset with associations between various temperature ranges and various powers. The main control module determines the temperature range to which it belongs based on the temperature data, and determines the target power based on the associations corresponding to the temperature ranges.

[0044] The relationship between each temperature range and each power is shown in Table 1 below: Table 1: Correlation between temperature range and power

[0045] It can be seen from Table 1 above that the higher the temperature, the lower the target power, that is, the value of the temperature data is negatively correlated with the target power.

[0046] Exemplarily, the signal transmitting device is configured to: After the control power module cuts off the power to the signal transmitter module, manual operation of the power module is required to restore the power to the signal transmitter module. In other words, manual intervention is required after entering the safe mode.

[0047] Exemplarily, the main control module is configured as follows: If the temperature range to which the temperature data belongs changes, the time of change and the temperature range to which it belongs after the change are recorded in the log.

[0048] For example, the present application also supports modifying the above-mentioned temperature ranges according to actual needs, or adding new correlations between temperature ranges and target powers, thereby improving the wide application of the present solution.

[0049] The above example uses multi-level temperature-power correlation control to proactively reduce the transmit power of the signal transmission module in high-temperature environments, preventing device damage from overheating. However, as ambient temperature rises, the device's heat dissipation efficiency decreases. Maintaining high transmit power prevents heat from being dissipated in a timely manner, further increasing component temperatures and creating a positive feedback loop. In this case, some energy is directly converted into ineffective heat rather than effective signal radiation. Therefore, compared to traditional fixed-power modes, this example reduces ineffective energy consumption and extends device life.

[0050] Furthermore, this application takes into account that the ambient temperature is not constant but fluctuates due to factors such as device heating and changes in the external environment. If a single threshold (such as 50°C) is directly used as the switching condition, the system will repeatedly switch between "normal mode" and "derated mode", resulting in the following undesirable situations: Hardware damage: Components such as power amplifiers age faster due to frequent starts and stops; Communication quality deteriorates: Sudden power changes cause signal amplitude / phase jumps, increasing the bit error rate (BER) at the receiving end. Energy waste: Mode switching itself requires additional energy consumption.

[0051] Therefore, the above example sets upper and lower thresholds to form an "insensitive zone" (buffer zone), triggering switching only when the temperature significantly exceeds or falls below the target range (i.e., state transition with hysteresis), thereby suppressing frequent switching.

[0052] Exemplarily, the main control module is configured to sample and process the temperature data monitored by the temperature and humidity sensor in the following manner: Sample the temperature data monitored by the temperature and humidity sensor according to the pre-configured sampling period; The moving average filtering algorithm is used to smooth the sampled raw temperature data to eliminate instantaneous fluctuation interference.

[0053] In a feasible design, the power environment parameter data includes voltage data, and the main control module is configured to generate a first instruction according to the power environment parameter data, including: The main control module is configured to determine a target power if the voltage data fluctuates abnormally within a first duration, where the target power is less than a normal power of the signal transmission module, where the normal power is the power used by the signal transmission module during normal operation; The main control module is configured to generate a first instruction according to the target power.

[0054] The description of abnormal fluctuation of voltage data within the first duration is described in the above example and will not be repeated here.

[0055] In an embodiment of the present application, the voltage acquisition sensor can not only acquire the voltage at the power equipment end, but also the voltage at the input end of the power module of the signal transmitting device. Because abnormal voltage fluctuations often lead to multiple low voltage situations, the above example actively reduces the power consumption of the signal transmitting module when the power supply is unstable, preventing the signal transmitting module from being unable to transmit signals at normal power when the voltage is low, thereby preventing communication interruption or hardware damage. This solution can improve the communication stability of the signal transmitting module in voltage fluctuation scenarios.

[0056] In a feasible design, the signal processing module is configured to adopt a heartbeat packet mechanism to periodically send data including timestamps and serial numbers to the cloud server, and / or, the signal processing module is configured to adopt an event trigger mechanism to immediately report key data related to the preset event to the cloud server when a preset event is detected.

[0057] Exemplarily, the preset events include abnormal power environment parameter data and / or user operations. Accordingly, if the preset event includes abnormal power environment parameter data, the key data includes the abnormal power environment parameter data and alarm information; if the preset event includes user operations, the key data includes the user operation object and the time when the user started the operation.

[0058] For example, when the signal processing module is configured to adopt the heartbeat packet mechanism, it sends a small data packet (referred to as a heartbeat packet) with a timestamp and sequence number to the cloud server every 5 minutes.

[0059] The above example uses a heartbeat packet mechanism to maintain persistent connections, monitor network status and device online status, and ensure real-time monitoring of network status. An event-triggered mechanism prioritizes the real-time performance of high-priority critical data. Immediate reporting of critical data avoids periodic heartbeat delays. Data is not transmitted during non-essential periods, reducing redundant communication. This mechanism enables the signal processing module to achieve reliable communication in complex network environments while meeting the combined low power consumption, low cost, and real-time requirements of IoT devices.

[0060] In a feasible design, it includes a dual user identity module slot, which has a main card and a secondary card built in the dual user identity module slot, and a signal processing module configured to maintain network connection through the secondary card when the signal quality of the main card meets the switching condition.

[0061] For example, the switching conditions include but are not limited to: The reference signal received power (RSRP) of the master card remains below the eighth threshold (for example, -110dBm). The signal-to-interference-plus-noise ratio (SINR) is lower than the ninth threshold. The ninth threshold can be set according to actual needs. The packet loss rate exceeds the first set value, which can be set according to actual needs; The delay exceeds the second set value (for example, 500ms). The second set value can be set according to actual needs.

[0062] The above example uses a dual-card redundant design to support automatic network switching, seamlessly switching to the backup link when the network signal is weak or interrupted, to ensure that the monitored power environment parameter data is transmitted back to the cloud server in real time, suitable for complex electromagnetic environments.

[0063] In a feasible design, an electromagnetic shielding module is included, which is used to isolate the electromagnetic interference between the power environment monitoring sensor group, the main control module, the signal transmission module and the sensor data acquisition circuit and the signal transmission module. The sensor data acquisition circuit is used to connect the power environment monitoring sensor group and the main control module.

[0064] Exemplarily, the electromagnetic shielding module includes a metal shielding layer, which is arranged around each line of the sensor data acquisition circuit in a closed shielding structure, and the minimum distance between each metal shielding layer and the antenna radiator of the signal transmission module is ≥10mm.

[0065] Exemplarily, the electromagnetic shielding module includes metal shielding covers, which are independently covered on the outside of the power environment monitoring sensor group, the main control module, and the signal transmission module. The minimum distance between each metal shielding cover and the antenna radiator of the signal transmission module is ≥10mm.

[0066] The above example uses an electromagnetic shielding module to reduce signal interference between the signal transmission module and the sensor data acquisition circuit, which not only improves the communication stability of the signal transmission module, but also improves the accuracy of data transmission from the power environment monitoring sensor group to the main control module through the sensor data acquisition circuit.

[0067] Further illustratively, if Figure 2 As shown, the sensor data acquisition circuit includes a first connection unit, a second connection unit, a third connection unit, and a fourth connection unit. The first connection unit is used to connect the voltage acquisition sensor to the main control module, the second connection unit is used to connect the temperature and humidity sensor to the main control module, the third connection unit is used to connect the current acquisition sensor to the main control module, and the fourth connection unit is used to connect the smoke acquisition sensor to the main control module. The first, second, third, and fourth connection units are deployed independently, meaning that the four lines are physically and logically independent of each other, and there is no overlap between the four lines.

[0068] This example avoids signal crosstalk and ensures data acquisition accuracy by designing each sensor to transmit data to the main control module through an independent channel. This makes it suitable for scenarios with complex electromagnetic environments and reduces the risk of misjudging key parameters (such as current mutations) due to common-mode interference.

[0069] In one feasible design, Figure 2 As shown, it includes a heat dissipation module, which is in communication with the main control module. The main control module is configured as follows: If each temperature data collected during the second duration exceeds the first threshold, a second instruction is sent to the signal processing module, the second instruction being used to obtain a signal packet loss rate within a target period, where the target period is determined based on the second duration; Obtain the signal packet loss rate from the signal processing module; If the signal packet loss rate is greater than a second threshold, the heat dissipation module is activated to cool the device.

[0070] The second duration, the first threshold, and the second threshold are set according to actual needs.

[0071] In this example, the power module is electrically connected to the heat dissipation module to provide power to the heat dissipation module.

[0072] Exemplarily, the heat dissipation module includes a fan.

[0073] Exemplarily, the main control module can control the heat dissipation module to stop working.

[0074] Exemplarily, the start time of the target period is the difference between the end time corresponding to the second duration and the second duration, and the end time of the target period is the end time corresponding to the second duration.

[0075] Exemplarily, the signal processing module is configured to determine the signal packet loss rate in the following manner: After sending a heartbeat packet to the cloud server, receive a data packet containing confirmation information returned by the cloud server; The packet loss rate is determined by comparing the number of heartbeat packets sent with the number of data packets received containing confirmation information.

[0076] Exemplarily, the second duration is set to 5 minutes, and the second threshold is set to 10%.

[0077] The above example uses a combined determination of packet loss rate and temperature to accurately identify cooling failures and prevent false triggering of the cooling module due to a single temperature threshold.

[0078] In a feasible design, the main control module is configured as follows: Obtaining received signal strength indication data from the signal processing module; Perform correlation analysis on the power environment parameter data and the received signal strength indicator data to determine the weight of each parameter data in the power environment parameter data; Determine the health status score of the device based on the weight of each parameter data; The score is sent to the cloud server through the signal processing module and the signal transmission module.

[0079] The following example illustrates the above example: (1) Data collection and preprocessing (1.1) Power environment parameter data collection: synchronously collect temperature, humidity, smoke concentration, voltage, and current data (sampling frequency 1Hz) and record timestamps.

[0080] (1.2) Received Signal Strength Indication (RSSI) Data Collection: Acquire RSSI data from the signal processing module. Convert the RSSI data to dBm and time-align it with the power environment parameter data.

[0081] To prevent future data from exceeding the standardized range and ensure scoring consistency across devices and scenarios, upper and lower limits can be defined for each of the above physical quantities. The upper and lower limits can be defined based on actual needs. Here is an example: Temperature: 0℃ (lower limit) ~ 90℃ (upper limit); Humidity: 0%RH (lower limit) ~ 100%RH (upper limit); Smoke concentration: 0ppm (lower limit) ~ 1000ppm (upper limit); Voltage: 0V (lower limit) ~ 240V (upper limit); Current: 0A (lower limit) ~ 240A (upper limit); (1.3) Data preprocessing (1.3.1) Data cleaning Eliminate abnormal values (such as instantaneous current out-of-range data) and interpolate missing values (using linear interpolation or front and back mean filling).

[0083] An example of a normal range definition (can be defined based on actual needs or industry standards): Temperature: 20℃~40℃, the standardized value range is [20 / 90, 40 / 90]≈[0.222, 0.444]; Humidity: 30%RH~70%RH, [30 / 100, 70 / 100]=[0.3, 0.7]; Smoke concentration: 0ppm~100ppm, [0, 100 / 1000]=[0, 0.1]; The normal ranges of voltage and current can be defined based on the above examples and actual needs, and will not be detailed here.

[0084] (1.3.2.2) Normalize the RSSI data as shown in the following formula (2): , formula (2); in, Indicates the initial value of RSSI data, Indicates the actual minimum value of RSSI data collected within the preset time period. Indicates the actual maximum value of RSSI data collected within the preset time period. Indicates the normalized value of RSSI data.

[0085] The above example can be performed periodically, and the operations of the above example are performed after each cycle. The above preset time period can be understood as the time period corresponding to the previous cycle.

[0087] (3) Determine the environmental health score according to the following formula (4):

[0088] , formula (4); Among them, 100 is the environmental health score The maximum value of . Indicates the penalty coefficient, which is used to amplify the deviation degree to a percentage score. It can be set according to actual needs, for example, 200. Used to quantify the degree to which parameter data deviates from the center point data of the normal range. express The normalized value of the center point data of the normal range of the corresponding parameter data is calculated as shown in the following formula (5): , formula (5); in, express The minimum value of the normal range of the corresponding parameter data, express The maximum value of the normal range of the corresponding parameter data, express The upper limit of the corresponding parameter data, express The lower limit of the corresponding parameter data.

[0089] (4) Determine the signal health score according to the following formula (6):

[0090] , formula (6); Among them, 100 is the signal health score The maximum value of Indicates the mean value of RSSI data in the previous period, Indicates the ideal RSSI value (that is, the RSSI value under the device's optimal working conditions, which can be selected based on experience). Indicates the packet loss rate. Indicates the RSSI allowable fluctuation range, which means that in actual applications, the RSSI data value is allowed to deviate The maximum range can be set according to actual needs. Is a weight distribution coefficient used to balance the impact of RSSI deviation penalty and packet loss rate penalty on the final score. Indicates RSSI deviation penalty, Indicates the packet loss rate penalty. This means that 10 points will be deducted for every 1% packet loss rate.

[0091] (5) Determine the comprehensive health score according to the following formula (7):

[0092] , formula (7); in, Indicates the weight corresponding to the environmental health score, which can be set according to actual needs. Comprehensive health score That is, the health status score of the device.

[0093] The above example objectively quantifies the impact of power environment parameter data on the communication quality of the signal transmission module through regression coefficients, avoiding subjective setting deviations. The health score of the device can be periodically output to maintenance personnel, allowing them to quickly understand the health status of the device.

[0094] Further illustratively, the main control module is configured as follows: The device is monitored by the device health score. If the device environmental health score is less than the tenth threshold, or the device signal health score is less than the eleventh threshold, an alarm message is sent to the cloud server through the signal processing module and the signal transmission module; If the comprehensive health score of the device is less than a twelfth threshold, the signal processing module controls the signal transmitting module to reduce the power of the transmitted signal.

[0095] Among them, the tenth threshold, the eleventh threshold and the twelfth threshold are set according to actual needs.

[0096] When each health scoring model identifies a low score, it triggers device actions (such as power reduction and network switching). The effects of these actions (such as RSSI recovery) are fed back into the establishment of the multiple linear regression model during subsequent correlation analysis, which can improve the real-time performance of the multiple linear regression model.

[0097] During long-term operation, the relationship between power environment parameter data and RSSI may shift due to equipment aging and environmental changes. The above example can periodically update the parameters of each model based on the latest data to ensure scoring accuracy.
