[0046] The signal acquisition module 12 is electrically connected to the water level monitoring module and the external damage monitoring module, respectively, and is used to receive the water level monitoring data, acceleration monitoring data, strain monitoring data and / or tilt angle monitoring data generated by them, and to perform collaborative processing on the data; the signal acquisition module 12 is built with a filtering algorithm and a compensation correction mechanism, which is used to perform mean filtering on the received water level signal and to perform compensation correction according to the geographical environment to ensure the accuracy of the data;

[0047] The storage module 13 is connected to the signal acquisition module for storing the set threshold information and the processed monitoring data;

[0048] The wireless communication module 14 encrypts and transmits the data collected in the data collection to the remote controller through a wireless narrowband communicator. The wireless communication module 14 is also equipped with an encryption mechanism for encrypting the data during the data transmission process to ensure the security of the data transmission.

[0049] In a specific example, the remote controller generates a primary warning when a single parameter reaches a set threshold; when multiple parameters are abnormal at the same time or a single data reaches a dangerous threshold, an advanced warning is generated.

[0050] Optionally, it also includes an audible and visual alarm module, which is connected to the signal acquisition module or the remote controller. When the remote controller determines that there is an abnormal situation, it triggers an audible and visual alarm to remind the staff.

[0051] More details of the present invention will be described below.

[0052] More specifically, in one embodiment of the present invention, the switch cabinet upper warning system based on wireless narrowband communication includes a water level monitoring module, an external damage monitoring module, a signal acquisition module, a storage module and a wireless communication module, the water level monitoring module and the external damage monitoring module are installed on the switch cabinet, the data collected by the water level monitoring module and the external damage monitoring module are transmitted to the signal acquisition module, and the signal acquisition module is connected to the remote controller through the wireless communication module; the water level monitoring module is installed on the side of the switch cabinet close to the water immersion direction, and the water level monitoring module is used to identify whether the water level reaches the set threshold; the external damage monitoring module is installed on the switch cabinet, and the external damage monitoring module identifies the damage of the switch cabinet by external force by monitoring the external force impact speed, impact deformation degree and / or tilt degree; the storage module can store the data collected by the signal acquisition module, or the set water level threshold or damage threshold information; the wireless communication module uses a 370MHz wireless narrowband communicator for encrypted transmission.

[0053] The water level monitoring module uses a water level sensor, which is suspended on the side of the switch cabinet close to the water immersion direction through a suspension bracket, and is connected to the signal acquisition unit through a junction box, which is mounted on the suspension bracket. The water immersion direction refers to the direction of the water level rising.

[0054] Among them, the water level sensor is an instrument that can convert the water level parameter of the measured point into the corresponding electrical signal in real time. When the water level around the switch cabinet is higher than the preset water level, the sensor will transmit the sensed water level signal to the controller. The computer in the controller will compare the measured water level signal with the set signal. The collected water level data may be affected by environmental noise (such as electromagnetic interference generated by electrical equipment, surrounding airflow, etc.). In order to improve the accuracy of the data, a filtering algorithm is used to process the data. For example, a mean filtering algorithm is used to average multiple collected data within a certain time window to remove random noise. At the same time, the water level data is compensated and corrected according to factors such as the installation location of the switch cabinet and the local geographical environment to ensure the accuracy of the measurement results.

[0055] Furthermore, the water level sensor uses a static pressure immersion type liquid level transmitter or a immersion split type liquid level sensor. Among them, the static pressure immersion type liquid level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid, converts the static pressure into an electrical signal, and then converts it into a standard electrical signal after temperature compensation and linear correction. The immersion split type liquid level sensor adopts the principle that the water pressure is proportional to the height of the water. When the water level sensor is immersed in a certain depth in the measured liquid, the pressure on the sensor facing the liquid surface is introduced into the positive pressure chamber of the sensor through the air-conducting stainless steel. Then the atmospheric pressure on the liquid surface is connected to the negative pressure chamber of the sensor to offset the atmospheric pressure on the back of the sensor, so that the sensor measures the pressure. By measuring the pressure, the liquid level height can be obtained.

[0056] The external damage monitoring module includes a tilt sensor, an acceleration sensor and / or a strain sensor, and any at least two of the sensors form a group of components. The external damage monitoring module is provided with four groups of components and is respectively arranged at the four corners of the switch cabinet.

[0057] Among them, the tilt sensor is an inclinometer: it works based on the principle of gravity. There is a sensitive element (such as a pendulum, liquid or acceleration sensor, etc.) inside the tilt sensor. When the switch cabinet tilts, the angle of the sensitive element relative to the direction of gravity changes, and this change is converted into an electrical signal output. For example, the tilt sensor based on the acceleration sensor calculates the tilt angle of the switch cabinet by using the trigonometric function relationship between the components of acceleration in different directions and the tilt angle. The collected tilt angle data needs to be processed for stability. Since factors such as small external vibrations may cause fluctuations in the angle data, a filtering algorithm (such as low-pass filtering) is used to remove high-frequency noise and obtain a stable tilt angle value. At the same time, the tilt threshold is set according to the installation requirements of the switch cabinet. When the angle value exceeds the set threshold, it is determined that the switch cabinet is tilted abnormally and the early warning mechanism is triggered.

[0058] Among them, the acceleration sensor, when the switch cabinet is hit by external force, the acceleration will change suddenly. The acceleration sensor can sense this change in acceleration and convert it into an electrical signal. For example, the piezoelectric acceleration sensor uses the piezoelectric effect of the piezoelectric crystal. When it is subjected to acceleration, the crystal generates a charge signal proportional to the acceleration; the piezoresistive acceleration sensor is based on the piezoresistive effect of semiconductor materials. Acceleration causes the piezoresistive element inside the sensor to deform, thereby changing its resistance value, and the acceleration information is obtained by measuring the resistance change.

[0059] Among them, the strain sensor is a strain gauge pasted on the key parts of the switch cabinet (such as the corners that are vulnerable to impact). When the switch cabinet is deformed by impact, the strain gauge will also deform accordingly. According to the resistance strain effect of the strain gauge (strain causes the resistance value to change), the deformation of the switch cabinet is converted into an electrical signal, thereby detecting the external force impact. The collected strain signal is analyzed and processed. First, a threshold judgment algorithm is used to set a reasonable strain threshold. When the collected signal value exceeds the threshold, it is determined that an external force impact has occurred. In order to more accurately judge the severity, direction and other information of the impact, a signal feature analysis method is used, such as spectrum analysis of the strain signal, to obtain the size and direction of the deformation, thereby judging the energy size and direction information of the impact.

[0060] It also includes a camera, a temperature sensor and a humidity sensor, and the camera, the temperature sensor and the humidity sensor are all electrically connected to the signal acquisition module. After receiving the early warning, the monitoring personnel can use the camera to more intuitively judge the on-site situation, avoid misjudgment and waste manpower, and save manpower costs. A humidity sensor and a temperature sensor are also provided in the switch cabinet. The temperature sensor is provided in the switch cabinet, and the humidity sensor is provided near the electronic device. The temperature sensor and the humidity sensor are connected to the signal acquisition unit.

[0061] The wireless communication module uses a 370MHz wireless narrowband communicator for encrypted transmission. 370MHz wireless narrowband communication technology is a wireless communication technology specifically used for low-power, long-distance data transmission. The data acquisition and processing unit in the equipment encodes and modulates the monitored water immersion and external damage data, and sends it out through the 370MHz frequency band wireless transmission module. At the receiving end (the monitoring platform of the back-end operation and maintenance staff on duty), the wireless receiving module demodulates and decodes the signal after receiving it to restore the original monitoring data. This communication technology has narrowband characteristics and can achieve stable data transmission at a lower bandwidth, reducing signal interference and improving communication reliability.

[0062] It can be understood that in the present invention, the present invention applies to integrate multiple parameters such as flooding monitoring (water level and humidity) and external damage monitoring (impact and tilt) into one system. Through multi-sensor data fusion technology, the correlation and mutual influence between different monitoring parameters are comprehensively analyzed to achieve all-round and multi-dimensional status monitoring of outdoor power switch cabinets. For example, when the water level rises to a certain level, it may increase the risk of the cabinet body tilting or being damaged after being hit by external force. The system can take this correlation into account and adjust the early warning strategy.

[0063] Based on the comprehensive analysis results of water flooding and external damage monitoring data, graded warnings are implemented. When a single parameter is detected to be abnormal, a primary warning is issued; when multiple parameters are abnormal at the same time or the abnormal situation reaches a certain severity, a high-level warning is issued. This collaborative warning mechanism can more accurately reflect the actual safety status of the switchgear and avoid misjudgments that may be caused by single parameter warnings.

[0064] In another embodiment, an environmental adaptive algorithm is set up to enable the equipment to automatically adjust the monitoring strategy according to the real-time changes in the outdoor environment. For example, in an environment with large changes in temperature and humidity, the algorithm can automatically compensate for the measurement error of the sensor; in thunderstorms, the system can temporarily increase the monitoring frequency of the switch cabinet status to promptly detect the risk of external damage or flooding caused by lightning strikes.

[0065] The system has intelligent fault diagnosis function and can monitor the working status of its components in real time. When a sensor or communication module fails, the system can automatically diagnose the cause of the failure and try to self-repair through software algorithms or spare hardware modules. If self-repair is not possible, the system will promptly send fault alarm information to the monitoring center so that maintenance personnel can quickly repair it.

[0066] like Figure 2 FIG. 1 is a schematic diagram showing the main process of an embodiment of a switch cabinet upper warning method provided by the present invention. Figure 3 As shown, in this embodiment, the method includes the following steps:

[0067] Step S10, using a plurality of pre-installed sensors to respectively perform water level monitoring, acceleration monitoring, strain monitoring and / or tilt angle monitoring on the switch cabinet;

[0068] In a specific example, the step S10 further includes:

[0069] When the water level around the switch cabinet is higher than the set threshold, the water level sensor transmits the monitored water level signal to the signal collector; specifically, the water level signal collected by the water level sensor adopts a mean filtering algorithm to average multiple collected water level signals within a set time to remove random noise. At the same time, the water level data is compensated and corrected according to factors such as the installation location of the switch cabinet and the local geographical environment to determine the final accurate water level monitoring data. It can be understood that in this embodiment, the anti-waterlogging data processing algorithm used in water level signal collection can include the following steps: 1) Processing data using a filtering algorithm: Due to the complex outdoor environment, the data collected by the water level and humidity sensors may be subject to various interferences. An effective filtering algorithm, such as Kalman filtering or wavelet filtering, is used to remove noise interference and improve the accuracy and stability of the data. 2) Setting and dynamic adjustment of thresholds: According to the structural characteristics, geographical location and historical operation data of the switch cabinet, reasonable water level and humidity thresholds are set. At the same time, considering the environmental changes under different seasons and weather conditions, the thresholds should have dynamic adjustment capabilities to reduce false alarms and missed alarms. For example, the water level warning threshold can be appropriately lowered in the rainy season, while the humidity warning threshold can be correspondingly increased in the dry season;

[0070] When the switch cabinet is impacted by external force, the acceleration change value is monitored by the acceleration sensor and transmitted to the signal collector; further comprising: using a threshold judgment algorithm to set a reasonable acceleration threshold; when the collected signal value exceeds the threshold, it is determined that an external force impact has occurred; using a signal characteristic analysis method to perform spectrum analysis on the acceleration signal to obtain the frequency component of the impact, thereby determining the impact direction information; wherein, if a piezoelectric acceleration sensor is used, it uses the piezoelectric effect of the piezoelectric crystal. When it is subjected to acceleration, the crystal generates a charge signal proportional to the acceleration; if a piezoresistive acceleration sensor is used, based on the piezoresistive effect of semiconductor materials, the acceleration causes the piezoresistive element inside the sensor to deform, thereby changing its resistance value, and the acceleration information is obtained by measuring the resistance change;

[0071] When the switch cabinet is deformed by impact, the strain sensor attached to the key part of the switch cabinet is deformed accordingly. According to the resistance strain effect of the strain sensor, the deformation data of the switch cabinet is transmitted to the signal collector. Specifically, when the switch cabinet is impacted by external force, the acceleration change value is monitored by the acceleration sensor and transmitted to the signal collector. Among them, a threshold judgment algorithm is first used to set a reasonable strain threshold. When the collected signal value exceeds the threshold, it is determined that an external force impact has occurred.

[0072] When the switch cabinet tilts, the angle of the tilt sensor relative to the direction of gravity changes, and the angle change data is transmitted to the signal collector; specifically, the collected tilt angle data is processed for stability to reduce the fluctuation of the angle data caused by tiny external vibrations, and a filtering algorithm is used to remove high-frequency noise to obtain a stable tilt angle value.

[0073] Step S11, collecting water level monitoring data, acceleration monitoring data, strain monitoring data and / or tilt angle monitoring data, and collaboratively processing the data;

[0074] Step S12, encrypting and transmitting the data collected in the data collection to the remote controller through the wireless narrowband communicator;

[0075] Step S13: When the remote controller detects that a single parameter reaches a set threshold, a primary warning is generated; when multiple parameters are abnormal at the same time or a single data reaches a dangerous threshold, a high-level warning is generated.

[0076] In a specific example, the method further includes: when a primary warning or a high-level warning is detected, an alarm sound is emitted through a buzzer, and a light-emitting diode or a warning light is controlled to flash, so as to warn the staff. Specifically, the buzzer is driven by a control circuit to emit an alarm sound, and the sound intensity is sufficient to attract the attention of nearby personnel (for example, reaching more than 80 decibels); at the same time, the light-emitting diode or the warning light is controlled to flash, and the light is visible at a long distance (for example, more than 20 meters), so that the on-site personnel can promptly discover the abnormal situation of the switch cabinet.

[0077] Workers can also view the interface of the switch cabinet upper warning system and on-site image information through APP software. Figure 3 As shown, a schematic diagram of an interface is shown.

[0082] In an embodiment of the present invention, comprehensive real-time monitoring of the switch cabinet environment is achieved through multi-sensor fusion monitoring, early warning is issued in time, and fault response time is reduced. Automated monitoring reduces the need for manual inspections, reduces labor intensity and maintenance costs. Timely early warning helps prevent serious faults and ensure the safety of power supply.
