[0072] According to an embodiment of the present invention, the data collection module includes sensors or devices such as voltage sensors and image capture devices that can collect data. For example, the voltage value of electrical equipment in the substation is collected by a voltage sensor, and images around the substation and inside the substation are captured by an image capture device. The collected data is sent to the data processing module for processing. When the data is normal, no control information is generated. When the data is abnormal, a judgment is made based on pre-set parameters, and corresponding control information or warning information is generated, such as power-off control information of the equipment, ventilation control information, illegal intrusion warning information, etc.; the data temporary storage module periodically sends the temporarily stored data to a preset power center for backup and preservation.

[0073] According to an embodiment of the present invention, the data collection module includes: a time sensor, a voltage sensor, a current sensor, a temperature sensor, a humidity sensor, a sound sensor, an image capture device and a gas detection device;

[0074] The time sensor is used to mark the time of the collected data and determine the time node of each data;

[0075] The voltage sensor is used to collect voltage values ​​of equipment in the substation;

[0076] The current sensor is used to collect the current value of the equipment in the substation;

[0077] The temperature sensor is used to collect the temperature values ​​of the equipment in the substation and the temperature values ​​of the environment in which the substation is located;

[0078] The humidity sensor is used to collect humidity values ​​of equipment in the substation and humidity values ​​of the environment inside and outside the substation;

[0079] The sound sensor is used to collect sound data information;

[0080] The image capturing device is used to collect image data inside and outside the substation;

[0081] The gas detection device is used to detect the gas composition of the environment in which the substation is located and the proportion of the corresponding gas composition.

[0082] It should be noted that when the data collection module collects data, the collection end will mark the collected data according to the current time and determine the time node of the corresponding collected data. In addition, the data collection end will add corresponding labels to the corresponding data to facilitate matching with each unit in the data processing module. For example, the voltage data collected by the voltage sensor is marked with a voltage label, and the current data collected by the current sensor is marked with a current label.

[0083] According to an embodiment of the present invention, the data processing module includes: a voltage data processing unit, a current data processing unit, a temperature data processing unit, a humidity data processing unit, a sound data processing unit, an image data processing unit and a gas data processing unit;

[0084] The voltage data processing unit is used to set the standard voltage value range of each device, and to determine the collected voltage value according to the standard voltage value range of the corresponding device. If the collected voltage value is not within the standard voltage value range of the corresponding device, the device corresponding to the voltage value is marked as having a voltage error once;

[0085] The current data processing unit is used to set the standard current value range of each device, and to determine the collected current value according to the standard current value range of the corresponding device. If the collected current value is not within the standard current value range of the corresponding device, the device corresponding to the current value is marked as having a current error once;

[0086] The temperature data processing unit is used to set the standard temperature value range of the environment in which each device or substation is located, and to determine the collected temperature value according to the standard temperature value range of the environment in which the corresponding device or substation is located. If the collected temperature value is not within the standard temperature value range of the environment in which the corresponding device or substation is located, the temperature is marked as too high once;

[0087] The humidity data processing unit is used to set the standard humidity value range of each device or the internal environment of the substation, and to determine the humidity value of the device in the substation and the humidity value of the internal environment of the substation according to the standard humidity value range of the corresponding device or the internal environment of the substation. If the humidity value of the device in the substation or the humidity value of the internal environment of the substation is not within the standard humidity value range of the environment in which the corresponding device or substation is located, the humidity is marked as too high once;

[0088] The sound data processing unit is used to process the sound data;

[0089] The image data processing unit is used to process the image data;

[0090] The gas data processing unit is used to set the standard proportion range of the air components in the environment of the substation. If the proportion value of the detected gas component is greater than the standard proportion range of the corresponding gas in the air component, ventilation prompts and air hazard warning information are triggered.

[0091] It should be noted that the voltage data is matched with the voltage data processing unit through the corresponding voltage label, and then the standard voltage value range of the corresponding device is found for judgment. For example, if the voltage value of time node a in the voltage data is not within the standard voltage value range of the corresponding device, then the voltage error of the device at time node a is recorded once.

[0092] According to an embodiment of the present invention, the voltage data processing unit is further used for:

[0093] Obtain the total number of times that voltage error is marked for the same device within a preset first time period;

[0095] The power-off control information of the device is sent to the control and warning module.

[0096] It should be noted that, for example, if the voltage of the same device is wrong once at time node a and once at time node b, and the time difference between time node a and time node b is less than the preset first time period, then the corresponding device has two voltage errors within the preset first time period.

[0097] According to an embodiment of the present invention, the current data processing unit is further used for:

[0098] Obtaining the total number of times that the current of the same device is marked as wrong within a preset second time period;

[0099] Determine whether the total number of times that the current error is marked for the same device within a preset second time period is greater than a preset second number threshold, and if so, generate power-off control information for the corresponding device;

[0100] The power-off control information of the device is sent to the control and warning module.

[0101] It should be noted that, for example, if the current of the same device is wrong once at time node c and once at time node d, and the time difference between time node c and time node d is less than the preset second time period, then the corresponding device has two current errors within the preset second time period.

[0102] According to an embodiment of the present invention, the temperature data processing unit is further used for:

[0103] Obtaining a total number of times that the temperature is marked as too high within a preset third time period;

[0104] Determine whether the total number of times the temperature is marked as too high within the preset third time period is greater than a preset third number threshold, and if so, generate ventilation control increase information;

[0105] The increased ventilation control information is sent to the control and warning module.

[0106] It should be noted that the ventilation control is divided into levels according to the ventilation effect, wherein the higher the level, the better the corresponding ventilation effect. When the total number of times the temperature is marked as too high within the preset third time period is greater than the preset third number threshold, the temperature value corresponding to the temperature marked as too high within the preset third time period is extracted, and the corresponding temperature value is averaged to obtain a first temperature average value. The first temperature average value is subtracted from the maximum value of the standard temperature value range for the corresponding temperature judgment to obtain a second temperature average value. The second temperature average value is multiplied by the preset first level weight to obtain an increased ventilation control level. If the increased ventilation control level is a non-integer, it is rounded up to the nearest integer. The increased ventilation control information includes the increased ventilation control level of the current fan.

[0107] According to an embodiment of the present invention, the humidity data processing unit is further used for:

[0108] Obtain the total number of times the humidity is marked as too high within a preset fourth time period;

[0109] If the total number of times the humidity is marked as too high within the preset fourth time period is greater than the preset fourth number threshold, extracting the external environment humidity value set and the internal environment humidity value set of the substation in the preset fourth time period;

[0110] The humidity values ​​in the external environment humidity value set are averaged to obtain the external environment humidity average value, and the humidity values ​​in the external environment humidity value set are averaged to obtain the internal environment humidity average value;

[0111] If the average external humidity is greater than the average internal humidity, a high humidity warning message is triggered;

[0112] If the average value of the external environment humidity is less than or equal to the average value of the internal environment humidity, then the ventilation control information is generated;

[0113] The excessive humidity warning information or the increased ventilation control information is sent to the control and warning module.

[0114] It should be noted that when the total number of times the humidity is marked as too high within the preset fourth time period is greater than the preset fourth number threshold, the humidity value corresponding to the humidity being marked as too high within the preset fourth time period is extracted, and the corresponding humidity value is averaged to obtain a first humidity average value, and the maximum value of the standard humidity value range corresponding to the humidity judgment is subtracted from the first humidity average value to obtain a second humidity average value, and then the second humidity average value is multiplied by the preset second level weight to obtain an increased ventilation control level. If the increased ventilation control level is a non-integer, it is rounded up to the nearest integer. The increased ventilation control information includes the increased ventilation control level of the current fan.

[0115] According to an embodiment of the present invention, the sound data processing unit is further used for:

[0116] Extract the sound data in layers to obtain sound sub-data of multiple devices;

[0117] Determine whether the sound feature in the sound sub-data is within the preset sound feature range of the corresponding device. If so, the corresponding device is normal; if not, trigger a warning message of the corresponding device;

[0118] Based on the warning information of the corresponding device, generate control information for shutting down the device;

[0119] The control information for shutting down the device or the warning information of the corresponding device is sent to the control and warning module.

[0120] It should be noted that the sound data is extracted in layers through audio separation technology to determine the sound sub-data of different devices, and then the sound features in the sound sub-data are compared and analyzed with the preset sound features to determine the sound similarity value. If the sound similarity value is greater than the preset sound similarity threshold, the device corresponding to the sound sub-data is set to be the same as the device corresponding to the preset sound feature, thereby determining the device corresponding to the sound sub-data, and based on the device corresponding to the sound sub-data, the preset sound feature range of the corresponding device is searched, and the preset sound feature range includes volume and pitch.

[0122] Extract elements and corresponding element features from image data;

[0124] If the first similarity value is greater than a preset first similarity threshold, extracting the corresponding element feature;

[0125] Determine the element feature and compare it with a preset element feature to obtain a second similarity value;

[0126] If the second similarity value is greater than or equal to the preset second similarity threshold, the corresponding image is normal; if the second similarity value is less than the preset second similarity threshold, an illegal intrusion warning message is generated;

[0127] The illegal intrusion warning information is sent to the control and warning module.

[0128] It should be noted that the substation is monitored inside and outside by an image capture device. For example, the image data of the outside of the substation, including the animals and plants around the substation, the corresponding elements are the animals and plants around the substation. The elements are individuals in the image, and the element features are a certain feature of the individuals in the image. For example, if there is an animal in the image data, the color of the animal is the element feature. The image capture device is used to prevent illegal intrusion or damage by non-technical personnel.

The warning information includes air hazard warning information, illegal intrusion warning information, etc.; the control information includes information for increasing fan control, control information for shutting down equipment, etc.; further, the fan control subunit is also used to extract the ventilation control level of the current fan, and add the ventilation control level of the current fan and the increased ventilation control level in the increased fan control information to obtain the ventilation control revision level; if the ventilation control revision level is greater than the maximum ventilation control level of the corresponding fan, the ventilation warning information is triggered. And ventilation is carried out at the maximum ventilation control level; if the ventilation control revision level is less than or equal to the maximum ventilation control level of the corresponding fan, the current ventilation control level is adjusted and replaced according to the ventilation control revision level; further, when the increase of the ventilation control level is not triggered in the substation, the corresponding retention time value is extracted, and if the retention time value is greater than the preset first time threshold, the ventilation control level reduction information is generated, and the ventilation control level is reduced by one level based on the ventilation control level reduction information until the current ventilation control level is the preset ventilation control level; further, when there are multiple ventilation control level increases at the same time, the highest ventilation control level shall prevail, and the ventilation control revision level shall be greater than the maximum ventilation control level of the corresponding fan.
