[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Example 1

[0029] like Figure 1 As shown, this application provides a safety monitoring method for an electric heating transformer protection system, the method comprising the following steps:

[0030] Step S1: Collect monitoring data of the operating status parameters of each device in the electric heating transformer protection system within multiple business analysis areas, and obtain the associated parameter data of each device.

[0031] like Figure 2 As shown, step S1 includes the following sub-steps:

[0032] Step S110: Set up corresponding data acquisition equipment for each device in the electric heating transformer protection system within multiple business analysis areas.

[0033] Step S120: Collect monitoring data of the operating status parameters of the corresponding device through the set data acquisition equipment.

[0034] Step S130: Obtain the associated parameter data of the device based on the device's operating status parameter monitoring data.

[0035] As a specific embodiment of the present invention, the associated parameter data of the device is obtained based on the current device's operating status parameter monitoring data. That is, the number of other devices whose operating status data is also obtained at the same time as the current device's operating status data is obtained. If the operating status of another device is also within a certain data range of the current device's operating status data, then the operating status of the two devices is related.

[0036] Specifically, multiple data acquisition devices within the Internet of Things (IoT) collect monitoring data and related parameter data of various devices in the electric heating transformer protection system. These data acquisition devices include, for example, voltage sensors, current sensors, power sensors, and temperature sensors. Multiple data acquisition devices from the same electric heating transformer protection system are integrated into the same IoT network, which also includes a gateway. This allows the multiple data acquisition devices to transmit their collected data to the gateway, which then transmits it to the data management platform.

[0037] Specifically, the monitoring data for operating status parameters includes fault data and over-limit data. Fault data includes line leakage, overload, short circuit faults, etc., while over-limit data includes operating voltage over-limit, operating current over-limit, output power over-limit, temperature over-limit, and reactive power over-limit (caused by losses in the power supply transformer and transmission lines), etc.

[0038] Specifically, associated parameter data refers to a situation where the monitoring data of a certain operating status parameter of a certain device exceeds the preset parameter, which causes the monitoring data of the operating status parameter of another device to also exceed the preset parameter. For example, associated parameter data is the number of other devices whose operating parameters are detected by a certain device to exceed the preset threshold, or the number of other devices whose exceeding data of a certain device causes the exceeding data to occur.

[0039] The devices in the electric heating transformer protection system include a transformer detector, a power controller, and a background processor.

[0040] Among them, the transformer detector is installed at the transformer end to monitor the transformer's usage status in real time.

[0041] Among them, the power controller is installed in the household box or floor box and is used to regulate the incoming power of the user.

[0042] The background processor, also known as the background server, compares the detected transformer usage (power) with the preset warning power. When the detected transformer power exceeds the warning power, the background processor sends a command to the power controller to reduce the user's power usage and ensure the normal operation of the transformer.

[0043] As a specific embodiment of the present invention, the background server sets the following parameters: a maximum value A (this value is 5% smaller than the actual maximum value of the transformer), and a set value B, where the set value B is less than A.

[0044] In a specific embodiment of the present invention, the current detector transmits the real-time current of the transformer to the backend server. The backend server compares the detected real-time current with a set value B. When the detected value ≤ B, the backend sends a command to the power controller to keep the power controller operating at maximum power. When A > detected value > B, the server sends a command to the power controller to reduce the control power of the power controller, reducing the total power of the power controller by 10% each time. After the reduction is completed, the current detector detects the real-time power of the transformer. If the real-time power of the transformer is still A > detected value > B, the server continues to send a command to the power controller to reduce the total power by 10%. After the power controller completes this process, it continues to detect the real-time current of the transformer and repeats the above actions until the detected value ≤ B, at which point the action stops and the system operates in this state. The current detector continues to detect the current. When the current is less than 10% of the value B and remains so for 30 minutes, the backend sends a command to the power controller to increase the control power by 5%. After the power controller completes this process, the current detector continues to detect the current. When the current is less than 10% of the value B and remains so for 10 minutes, the server sends a command to the power controller to increase the control power by 5%, and this cycle continues until the power controller returns to its maximum value.

[0045] As a specific embodiment of the present invention, the temperature regulation status control method of each electric heating device is as follows: the control center integrates the information of the power generation side and the power consumption side to determine whether it is necessary to issue a load reduction signal. When it is necessary to reduce the load, the control center sends the reduction signal to the electric heating control terminal, and then the electric heating control terminal sends it to the corresponding gateway of the electric heating device. The gateway converts the load reduction signal into a temperature regulation signal of the electric heating device.

[0046] Step S2: Transmit the monitoring data of the running status parameters and the associated parameter data to the data management platform.

[0047] Step S2 includes the following sub-steps:

[0048] Step S210: Establish storage blocks for each business analysis area on the data management platform.

[0049] Different storage blocks are established for different business analysis areas.

[0050] As a specific embodiment of the present invention, encryption protection is established for each storage block to prevent the data stored in the storage block from being illegally stolen. Encryption protection methods include, for example, key encryption, certificate encryption, or ciphertext encryption.

[0051] Step S220: Identify the business analysis area to which the monitoring data of the operating status parameters and the associated parameter data uploaded to the data management platform belong.

[0052] In a specific embodiment of the present invention, the data acquisition device uploads the collected data (operational status parameter monitoring data and associated parameter data) to the data management platform through a gateway. Based on the business analysis area corresponding to the data acquisition device that uploaded the operation status parameter monitoring data and associated parameter data, the business analysis area to which the operation status parameter monitoring data and associated parameter data transmitted to the data management platform belong is identified.

[0053] Step S230: Based on the business analysis area to which the operation status parameter monitoring data and related parameter data belong, store the operation status parameter monitoring data and related parameter data in the corresponding storage block of the data management platform.

[0054] As a specific embodiment of the present invention, the data collected for each business analysis area is classified and stored in the data management platform.

[0055] Specifically, each business analysis area may be, for example, a factory building, a residence, or a public place. The monitoring data and related parameter data of each device in the electric heating transformer protection system within the same business analysis area are stored together, while the monitoring data and related parameter data of each device in different electric heating transformer protection systems within the same business analysis area are stored in different locations. The data management platform provides a database to store the collected monitoring data and related parameter data.

[0056] Step S3: Based on the monitoring data of operating status parameters and related parameter data collected within the business analysis area, calculate the operating hazard value of the electric heating transformer protection system in the business analysis area.

[0057] Specifically, the data processing platform receives the monitoring data of operating status parameters collected by various data acquisition devices through the gateway. Then, based on the monitoring data of operating status parameters and related parameter data collected in any business analysis area, it calculates the operating hazard value of the electric heating transformer protection system in the current operating state of that business analysis area.

[0058] Specifically, the calculation formula for the operational hazard value of the electric heating transformer protection system is as follows:

[0059]

[0060] Where Wq represents the operational hazard value of the electric heating transformer protection system; f1 represents the impact weight of the fault data; Q represents the total number of devices in the electric heating transformer protection system; Aq represents the total number of fault data types for the q-th device in the electric heating transformer protection system; y qa This represents the danger value of the a-th type of fault data for the q-th device in the electric heating transformer protection system; LG qa The other device correlation factor represents the fault data of the q-th device in the electric heating transformer protection system for the type a fault; f2 represents the influence weight of the out-of-limit data; Rq represents the total number of out-of-limit data types for the q-th device in the electric heating transformer protection system; e qr P represents the weighting factor for the r-th type of out-of-limit data of the q-th device in the electric heating transformer protection system; qr PB represents the measured value of the r-th type of out-of-limit data for the q-th device in the electric heating transformer protection system. qr This represents the standard value corresponding to the r-th type of out-of-limit data of the q-th device in the electric heating transformer protection system; LC qr The other device correlation factor represents the q-th device and the r-th type of out-of-limit data in the electric heating transformer protection system.

[0061] Among them, LG qa =NQ qa +1;

[0062] Among them, NQ qa This indicates the number of other devices that cause the a-type fault data to occur in the q-th device of the electric heating transformer protection system.

[0063] Among them, LC qr =NK qr +1;

[0064] Among them, NK qr This indicates the number of other devices in the electric heating transformer protection system that cause the r-th type of over-limit data to occur due to the q-th device.

[0065] Step S4: Compare the operational hazard value of the electric heating transformer protection system with the preset first threshold. If the operational hazard value of the electric heating transformer protection system is greater than the preset first threshold, then a comprehensive maintenance of the electric heating transformer protection system is required; otherwise, a comprehensive maintenance of the electric heating transformer protection system is not required.

[0066] As a specific embodiment of the present invention, the method for comprehensive maintenance of the electric heating transformer protection system includes: maintaining the transformer detector, power controller and background processor in the electric heating transformer protection system.

[0067] Step S5: Collect power consumption data and environmental data of the electrical equipment in the electric heating system.

[0068] Specifically, the electrical equipment used in electric heating systems includes the electrical heating equipment and the electrical equipment used in the electric heating transformer protection system (e.g., transformer detectors, power controllers, and background processors).

[0069] Specifically, the environmental data includes indoor space volume, indoor ambient temperature (indoor ambient temperature after the electric heating equipment is turned on), indoor ambient humidity (indoor ambient humidity after the electric heating equipment is turned on), initial indoor ambient temperature (indoor temperature when the electric heating equipment is not turned on), and initial indoor ambient humidity (indoor humidity when the electric heating equipment is not turned on).

[0070] Step S6: Calculate the energy utilization value of the electric heating system based on the power consumption data of the electrical equipment and environmental data of the electric heating system.

[0071] Specifically, the formula for calculating the energy utilization value of an electric heating system is as follows:

[0072]

[0073] Where Z represents the energy utilization value of the electric heating system; V represents the indoor space volume; α1 represents the influence weight of ambient temperature; α2 represents the influence weight of ambient humidity; c1 represents the set standard indoor ambient temperature; c0 represents the initial indoor ambient temperature; s1 represents the indoor ambient humidity at the end of sampling; s2 represents the initial indoor ambient humidity; N represents the total number of electric heating devices; M represents the total number of electrical devices in the electric heating transformer protection system; P 1 i P represents the electricity consumption of the i-th electric heating device within the sampling time; 2 j T1 represents the power consumption value of the j-th electrical equipment in the electric heating transformer protection system during the sampling time; T1 represents the time from the initial indoor ambient temperature to the set indoor standard ambient temperature. It can be understood that the sampling process collects power consumption data of the electric heating system's electrical equipment during the period from the initial indoor ambient temperature to the set indoor standard ambient temperature. Indoor ambient humidity refers to the indoor ambient humidity corresponding to when the indoor ambient temperature reaches the set indoor standard ambient temperature (at the end of sampling). Sampling ends when the indoor ambient temperature reaches the set indoor standard ambient temperature.

[0074] Step S7: Compare the energy utilization value of the electric heating system with the preset second threshold. If the energy utilization value of the electric heating system is less than the preset second threshold, adjust the energy consumption of the electric heating system equipment. Otherwise, there is no need to adjust the energy consumption of the electric heating system equipment.

[0075] As a specific embodiment of the present invention, the energy consumption regulation method includes, for example, lowering the indoor standard ambient temperature or inspecting the electric heating equipment (checking for leakage).
