[0075] Example 1

[0076] Figure 1 This is a flowchart of a method for determining the status of a terminal power supply device according to Embodiment 1 of the present invention. This embodiment is applicable to detecting the status of a terminal power supply device. The method can be executed by a status analysis module in the terminal power supply device status determination system. This status analysis module can be implemented in software, and the terminal power supply device status determination system can be applied to terminal power supply devices. Figure 1 As shown, the method includes:

[0077] S110. Obtain the operating data of the terminal power supply device and initialize the abnormal flag bit and the protocol incompatibility flag bit; wherein, the operating data includes: the voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information and smoke and open flame information of the terminal power supply device.

[0078] In this context, "terminal power supply equipment" refers to a power supply device within a power distribution automation terminal; "operational data" refers to data obtained by monitoring the terminal power supply equipment during operation using sensors or other monitoring devices; "identifier bits" refer to variables indicating the status or conditions of the monitoring program. Specifically, "abnormality identifier bits" indicate whether the monitoring terminal power supply equipment is experiencing abnormal operation; "protocol incompatibility identifier bits" indicate whether the monitoring terminal power supply equipment is experiencing protocol incompatibility, where protocol incompatibility refers to the communication protocol of the terminal power supply equipment being incompatible with the power distribution automation terminal protocol; "voltage" refers to the monitored voltage of the terminal power supply equipment; "current" refers to the monitored current of the terminal power supply equipment; "temperature" refers to the monitored temperature of the terminal power supply equipment; "remaining capacity" refers to the remaining charge of the battery pack in the terminal power supply equipment; "internal resistance" refers to the monitored internal resistance of the terminal power supply equipment; "protocol compatibility information" refers to information on whether the communication protocol of the terminal power supply equipment is compatible with the power distribution automation terminal protocol, specifically including the version and specifications of the communication protocols of the terminal power supply equipment and the power distribution automation terminal, and whether both parties follow the same standards or agreements; "smoke and flame information" refers to the smoke concentration and specific wavelength of the flame in the terminal power supply equipment, which can be monitored and identified using smoke and flame sensors. Among them, the flame sensor can detect ultraviolet flames, as flames produce ultraviolet light of a specific wavelength. Alternatively, it can detect infrared flames, which, similar to ultraviolet flame detection, produce infrared radiation within a wavelength range.

[0079] Specifically, terminal power supply equipment can be monitored using sensors or other monitoring devices to obtain its operating data. Initializing the exception flag and protocol incompatibility flag can mean setting both to 0.

[0080] In this embodiment, the operating data of the terminal power supply device can be obtained through sensors or other monitoring devices, and the abnormal flag bit and the protocol incompatibility flag bit can be initialized and set to 0.

[0081] S120. Update the anomaly flag and / or the protocol incompatibility flag based on the running data.

[0082] Specifically, updating the exception flag and / or protocol incompatibility flag can modify the exception flag and / or protocol incompatibility flag; for example, based on the operating data of the terminal power supply device, the initialized exception flag can be changed from 0 to 1 and / or the initialized protocol incompatibility flag can be changed from 0 to 1.

[0083] In this embodiment, the initialized abnormal flag bit and / or the protocol incompatibility flag bit can be updated based on the operating data of the terminal power supply device.

[0084] S130. Based on the updated anomaly flag and the updated protocol incompatibility flag, determine the operating status of the terminal power supply device.

[0085] The operating status of terminal power supply equipment refers to its current working condition and performance. Specifically, it can be key indicators reflecting whether the equipment is operating normally, experiencing abnormalities, or exhibiting protocol incompatibility. By determining the operating status of terminal power supply equipment in real time, potential problems can be identified and resolved promptly. This also reduces the operational and maintenance workload of staff, effectively protects against equipment asset losses, and improves the reliability and stability of the power distribution network.

[0086] Specifically, the operating status of the terminal power supply equipment can be one of the following: normal operating status, abnormal operating status, protocol incompatibility status, or abnormal operating status with protocol incompatibility.

[0087] In this embodiment, the operating data of the terminal power supply device is acquired, and the abnormality flag and protocol incompatibility flag are initialized. The operating data includes the voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke / open flame information of the terminal power supply device. The abnormality flag and / or the protocol incompatibility flag are updated based on the operating data. Based on the updated abnormality flag and the updated protocol incompatibility flag, the operating status of the terminal power supply device is determined. This solves the problem of long detection cycles and poor real-time performance of terminal power supply devices in existing technologies. By analyzing the operating data of the terminal power supply device, real-time determination of the operating status of the terminal power supply device is achieved, effectively saving the status detection time of the terminal power supply device, reducing the maintenance pressure on staff, and further improving the reliability and safety stability of the power distribution network.

[0088] Optionally, the exception flag and / or protocol incompatibility flag may be updated based on the operational data; including:

[0089] Obtain the abnormal conditions corresponding to voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke / open flame information;

[0090] Abnormal conditions may include:

[0091] 1. Determine whether the voltage of the terminal power supply device is within a preset voltage range;

[0092] 2. Determine whether the current of the terminal power supply device is within the preset current range;

[0093] 3. Determine whether the temperature of the terminal power supply device is within the preset temperature range;

[0094] 4. Determine whether the remaining capacity of the terminal power supply device supports a single full-power operation;

[0095] 5. Determine whether the internal resistance of the terminal power supply device is within the preset internal resistance range;

[0096] 6. Determine whether garbled characters appear in the protocol compatibility information of the terminal power supply device;

[0097] 7. If the flame sensor is an ultraviolet flame detector, the abnormal condition corresponding to the smoke and open flame information can be: determining whether the smoke concentration in the terminal power supply device exceeds a preset threshold and / or whether there is ultraviolet radiation of a specific wavelength. If the flame sensor is an infrared flame detector, the abnormal condition corresponding to the smoke and open flame information can be: determining whether the smoke concentration in the terminal power supply device exceeds a preset threshold and / or whether there is infrared radiation within a specific wavelength range.

[0098] Specifically, the preset voltage range, preset current range, preset temperature range, and preset internal resistance range are all pre-set, and can be pre-set according to user requirements in actual situations. A single full-power operation refers to the power and electricity required for the terminal power supply equipment to provide a single operation command to the switching operating mechanism, communication device, data acquisition, and other components of the distribution automation terminal. This value can be pre-set according to the actual situation of the distribution automation terminal during the installation of the terminal power supply equipment; the operation command is issued by the power grid company's distribution automation master station system. Garbled characters in the protocol compatibility information can be understood as garbled characters appearing after parsing the protocol compatibility information when it is abnormal. The preset threshold refers to a pre-set smoke concentration threshold, which can be comprehensively set according to application conditions, standards, and other factors.

[0099] In this embodiment, the voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke and flame information can be judged according to the pre-set abnormal conditions, thereby determining whether any abnormality has occurred in the voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke and flame information.

[0100] If at least one of the voltage, current, temperature, remaining capacity, internal resistance, and smoke / open flame information satisfies the corresponding abnormal condition, then the abnormal flag bit is updated;

[0101] Specifically, if any one of the following information is abnormal: voltage, current, temperature, remaining capacity, internal resistance, or smoke / flame information, the abnormality flag will be updated and the corresponding abnormality information will be saved.

[0102] 1. It can determine whether the voltage of the terminal power supply device is within the preset voltage range. If so, it can proceed to the next running data judgment. Otherwise, it can update the abnormal flag bit from 0 to 1 and save the voltage abnormality information. For example, the voltage abnormality information can be: the voltage of the terminal power supply device is abnormal, the voltage is too low, and it is A volts. Wherein, 0≤A≤A1, and A1 is the smaller voltage boundary value in the preset voltage range.

[0103] 2. Determine whether the current of the terminal power supply device is within the preset current range. If so, proceed to the next running data judgment. Otherwise, update the abnormal flag bit from 0 to 1 and save the current abnormal information. For example, the current abnormal information can be: the current of the terminal power supply device is abnormal, the current is too low, and it is B amperes; where 0≤B≤B1, and B1 is the smaller current boundary value in the preset current range.

[0104] 3. Determine whether the temperature of the terminal power supply device is within the preset temperature range. If so, proceed to the next running data judgment. Otherwise, update the abnormal flag bit from 0 to 1 and save the temperature abnormal information. For example, the temperature abnormal information can be: the temperature of the terminal power supply device is abnormal, the temperature is too high, and it is C degrees Celsius; where 0≤C≤C1, and C1 is the higher temperature boundary value in the preset temperature range.

[0105] 4. Determine whether the internal resistance of the terminal power supply device is within the preset internal resistance range. If so, the next running data can be judged. Otherwise, the abnormal flag bit can be updated from 0 to 1, and the internal resistance abnormal information can be saved. For example, the internal resistance abnormal information can be: the internal resistance of the terminal power supply device is abnormal, the internal resistance is too high, and it is D ohms; where 0≤D≤D1, and D1 is the larger internal resistance boundary value in the preset internal resistance range.

[0106] 5. Determine whether the remaining capacity of the terminal power supply device can support one full-power operation. If so, proceed to the next operation data judgment. Otherwise, update the abnormal flag bit from 0 to 1 and save the remaining capacity information. For example, the remaining capacity information can be: the remaining power of the battery pack in the terminal power supply device is 10% of the total power of the battery pack; or it can be: the remaining power of the battery pack in the terminal power supply device is E coulombs; where 0≤E≤E1, and E1 is the power required for the terminal power supply device to support one full-power operation.

[0107] 6. If the flame sensor is an ultraviolet flame detector, it can determine whether the smoke concentration in the terminal power supply device exceeds the preset threshold and / or whether there is ultraviolet light of a specific wavelength. If the smoke concentration does not exceed the preset threshold and there is no ultraviolet light of a specific wavelength, the next running data can be judged. If the smoke concentration exceeds the preset threshold and / or there is ultraviolet light of a specific wavelength, the abnormal flag bit can be updated from 0 to 1, and the smoke concentration value and / or ultraviolet wavelength can be saved.

[0108] If the flame sensor is an infrared flame detector, it can determine whether the smoke concentration in the terminal power supply device exceeds a preset threshold and / or whether there is infrared radiation within a specific wavelength range; if the smoke concentration does not exceed the preset threshold and there is no infrared radiation within a specific wavelength range, the next running data can be judged; if the smoke concentration exceeds the preset threshold and / or there is infrared radiation within a specific wavelength range, the abnormal flag bit can be updated from 0 to 1, and the smoke concentration value and / or infrared radiation wavelength can be saved.

[0109] If the protocol compatibility information meets the corresponding exception conditions, then the protocol incompatibility flag is updated.

[0110] Specifically, it determines whether there are garbled characters in the protocol compatibility information of the terminal power supply device; if not, it can proceed to the next running data judgment; if so, it can update the protocol incompatibility flag bit from 0 to 1 and save the protocol compatibility information. For example, the protocol compatibility information can include the version and specification of the communication protocol between the terminal power supply device and the power distribution automation terminal, as well as whether both parties follow the same standards or agreements.

[0111] In addition, the above judgments on voltage, current, temperature, remaining capacity, internal resistance, smoke and open flame information, and protocol compatibility information can be performed in parallel or in sequence. If it is a serial judgment, the order of judgment of each operating data is not important.

[0112] In this embodiment, abnormal conditions corresponding to voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke / open flame information are acquired. If at least one of the voltage, current, temperature, remaining capacity, internal resistance, and smoke / open flame information meets the corresponding abnormal condition, the abnormality flag is updated. If the protocol compatibility information meets the corresponding abnormal condition, the protocol incompatibility flag is updated. Based on the updated abnormality flag and the updated protocol incompatibility flag, the operating status of the terminal power supply equipment is determined. This achieves real-time determination of the operating status of the terminal power supply equipment, effectively saving the status detection time of the terminal power supply equipment, reducing the maintenance pressure on staff, and further improving the reliability and safety stability of the power distribution network.

[0113] Optionally, if at least one of the voltage, current, temperature, remaining capacity, internal resistance, and smoke / flame information meets the corresponding abnormal condition, the abnormal flag bit is updated, including:

[0114] If at least one of the voltage, current, temperature, remaining capacity, internal resistance, and smoke / open flame information meets the corresponding abnormal condition, the abnormal flag bit will be updated from the first bit to the second bit.

[0115] The first bit can be 0 and the second bit can be 1, meaning the initial error flag is 0 and the updated error flag is 1.

[0116] Specifically, the voltage, current, temperature, remaining capacity, internal resistance, and smoke / flame information are judged based on abnormal conditions. If at least one of the corresponding abnormal conditions is met, it indicates that the terminal power supply equipment is operating abnormally, and the abnormal flag bit can be updated from 0 to 1.

[0117] If the protocol compatibility information meets the corresponding exception conditions, then the protocol incompatibility flag is updated, including:

[0118] If the protocol compatibility information meets the corresponding abnormal conditions, the protocol incompatibility flag will be updated from the first bit to the second bit.

[0119] The first bit can be 0 and the second bit can be 1. That is, the protocol incompatibility flag is 0 after initialization and 1 after update.

[0120] Specifically, the protocol compatibility information is judged by the abnormal conditions corresponding to the protocol compatibility information. If the corresponding abnormal conditions are met, it indicates that the communication protocol between the terminal power supply equipment and the power distribution automation terminal is incompatible, and the protocol incompatibility flag can be updated from 0 to 1.

[0121] In this embodiment, the operating data of the terminal power supply device are judged by abnormal conditions, and the abnormal flag bit and / or protocol incompatibility flag bit are updated from the first bit to the second bit. Based on the updated abnormal flag bit and the updated protocol incompatibility flag bit, the operating status of the terminal power supply device is determined, realizing the real-time determination of the operating status of the terminal power supply device, effectively saving the status detection time of the terminal power supply device, reducing the operation and maintenance pressure of staff, and further improving the reliability and safety stability of the power distribution network.

[0122] Optionally, the operating status of the terminal power supply device is determined based on the updated anomaly flag and the updated protocol incompatibility flag, including:

[0123] If the anomaly flag is in the first position and the protocol incompatibility flag is in the first position, then the terminal power supply device is determined to be in normal operating condition.

[0124] If the anomaly flag is the first bit and the protocol incompatibility flag is the second bit, then the terminal power supply device is determined to be in a protocol incompatibility state.

[0125] If the abnormality flag is the second bit and the protocol incompatibility flag is the first bit, then the terminal power supply device is determined to be in an abnormal operating state.

[0126] If the abnormality flag is the second bit and the protocol incompatibility flag is the second bit, then it is determined that the terminal power supply device is in an abnormal operation and a protocol incompatibility state.

[0127] Specifically, if both the anomaly flag and the protocol incompatibility flag are 0, the terminal power supply is determined to be in normal operation; if the anomaly flag is 0 and the protocol incompatibility flag is 1, the terminal power supply is determined to be in a protocol incompatible state; if the anomaly flag is 1 and the protocol incompatibility flag is 0, the terminal power supply is determined to be in an abnormal operation state; if both the anomaly flag and the protocol incompatibility flag are 1, the terminal power supply is determined to be in both abnormal operation and protocol incompatible state.

[0128] In this embodiment, the operating status of the terminal power supply equipment is determined by the anomaly flag and the protocol incompatibility flag. If it is in normal operating status, the process ends. If it is in an abnormal operating status, a protocol incompatibility status, or an abnormal operating status with protocol incompatibility, corresponding maintenance warning information can be automatically generated based on the corresponding anomaly information. The anomaly information can refer to stored voltage anomaly information, current anomaly information, etc. This maintenance warning information is pre-set and corresponds to the anomaly information. Specifically, the maintenance warning information includes the maintenance location, distribution automation terminal information, operating anomaly information, and maintenance measures. For example, the maintenance location can be F power supply bureau, G power supply station, J line; the distribution automation terminal information can be: N pole, T1 terminal; the anomaly information can be that the terminal power supply equipment voltage is abnormal, low, at A volts; the corresponding maintenance measures can include checking the terminal power supply equipment lines, sockets, adapters, and the equipment itself; using a voltage regulator or uninterruptible power supply; preparing backup power; emergency contact information; data backup and recovery procedures, etc. By analyzing the operating data of the terminal power supply equipment, updating the abnormality flag and / or protocol incompatibility flag, and determining the operating status of the terminal power supply equipment based on the updated abnormality flag and updated protocol incompatibility flag, the status detection time of the terminal power supply equipment is effectively saved.

Figure 2 As shown, the device includes: a measuring component 11, a smoke sensor 12, a protocol compatible module 13, a flame sensor 14, a lithium battery pack 15, and a power management module 16.

[0131] The measuring components 11 include a temperature sensor, a voltage transformer, a current transformer, and an internal resistance measuring instrument, used to monitor the voltage, current, temperature, and internal resistance of the terminal power supply device.

The power management module 16 can control the battery pack to output 48 volts or 24 volts DC voltage according to the instructions issued by the user through the distribution automation terminal (or according to the control signals issued by the user through the terminal power supply equipment status determination system, where the terminal power supply equipment status determination system is a subsystem of the power grid company's distribution automation master station system), and can also realize the charging and discharging control of the battery pack and monitor the operating data of the terminal power supply equipment; the battery pack is a lithium battery pack 15, which consists of four lithium batteries. When all four lithium batteries work at the same time, they can output a DC voltage of 48 volts; when only two lithium batteries work at the same time, they can output a DC voltage of 24 volts.

[0136] In this embodiment, by setting measurement components 11, smoke sensors 12, protocol compatibility modules 13, flame sensors 14, lithium battery packs 15, and power management modules 16 in the terminal power supply device 10; wherein, the measurement components 11 include temperature sensors, voltage transformers, current transformers, and internal resistance measuring instruments, which facilitates the monitoring and acquisition of the terminal power supply device's operating data. This operating data includes: voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, and smoke and flame information of the terminal power supply device. Based on the judgment and analysis of the terminal power supply device's operating data, the operating status of the terminal power supply device is determined, which effectively saves the status detection time of the terminal power supply device, and can also automatically generate corresponding operation and maintenance early warning information, reducing the operation and maintenance pressure of staff, and further improving the reliability and safety stability of the power distribution network.

[0137] Optional, such as Figure 2 As shown, the terminal power supply device 10 also includes: a control module 17, an LCD screen 18, a data interface 19, a protection module 20, a status indicator light 21, a square fire extinguishing module 22, and a storage module 23;

[0138] The control module 17 is a control circuit board used to implement the software and hardware functions in the terminal power supply device;

[0139] The control circuit board can be used for precise control and adjustment of the terminal power supply equipment to realize the hardware and software functions within it. For example, by changing the state of electronic components in the terminal power supply equipment, the control circuit board can alter the magnitude and direction of current, ensuring the normal operation of the circuit system. It can control the power supply equipment to turn on and off via a switching circuit, and even achieve automatic start-up and shutdown of the terminal power supply equipment in intelligent designs.

[0140] The liquid crystal display screen 18 is an OLED liquid crystal display screen;

[0141] Specifically, it can display: the output voltage, current, power, temperature, remaining power, internal resistance, etc. of the terminal power supply device 10; basic information of the terminal power supply device 10, such as the model of the terminal power supply device 10, the unit to which it belongs, etc.; and the current power distribution automation terminal (FTU mode, DTU mode).

[0142] The data interface 19 includes: an RS-485 communication interface, an RJ-45 interface, and a USB interface;

[0143] Specifically, the RS-485 communication interface is mainly used for transmitting operating and status data of the terminal power supply equipment. Status data can refer to information from terminal power supply equipment status indicator lights (e.g., flashing red light, solid green light, etc.), flame sensor status information (flame present, no flame present), and protection module action status information (including overheat protection action status, overcurrent protection action status, and fault diagnosis and reset). The RJ-45 interface is mainly used for communication links between the terminal power supply equipment and the distribution automation terminal, enabling the transmission of data (e.g., operating data, status data) and signals (e.g., mode switching control signals between FTU and DTU modes) to the distribution automation master station system. The USB interface is mainly used for connecting to the computer of maintenance personnel to enable testing of the terminal power supply equipment and embedded software upgrades.

[0144] The protection module 20 includes an overheat protection element and an overcurrent protection element;

[0145] The overheat protection component monitors the temperature of the terminal power supply equipment in real time to ensure it operates within a safe range. When the temperature exceeds a preset safety threshold, the overheat protection component triggers an alarm signal to alert the user to the abnormal temperature. In extreme cases, such as when the temperature continues to rise and cannot be reduced through natural heat dissipation, the overheat protection component automatically cuts off the power supply to prevent damage to the terminal power supply equipment due to overheating. The overcurrent protection component monitors the current in the terminal power supply equipment circuit in real time to ensure the current flows within a safe range. When the current exceeds a preset safety value, the overcurrent protection component immediately issues an alarm signal to alert the user to the abnormal current. In cases where excessive current may cause circuit damage or fire, the overcurrent protection component automatically cuts off the power supply to protect the circuit and equipment.

[0146] Specifically, the protection module 20 records detailed information about each fault occurrence, including fault type, occurrence time, and duration, for subsequent analysis and processing. After the fault is cleared, the user can manually or automatically reset the protection module to restore it to normal working condition. The protection module 20 is also usually connected to a status indicator light 21 or an LCD screen 18 to display the current working status and fault information in real time, facilitating user monitoring and maintenance.

[0147] The status indicator 21 includes a running indicator, an error indicator, a data transmission indicator, and a data reception indicator;

[0148] The RUN indicator light shows a steady green light for normal startup, a flashing red light for a startup error, and no light for shutdown. The ERROR indicator light shows a flashing red light for a startup error. The TXD indicator light shows a flashing green light for data transmission. The RXD indicator light shows a flashing green light for data reception.

[0149] Specifically, when the RUN indicator light is flashing red, all other indicator lights are off. When the error indicator light is flashing red, the RUN indicator light is solid green, and the TXD and RXD data transmission indicator lights flash green or remain off depending on the actual situation.

[0150] The square fire extinguishing module 22 is used to realize the fire extinguishing function;

[0151] Specifically, the square fire extinguishing module 22 can release carbon dioxide to extinguish fires when activated.

[0152] The storage module 23 is used to implement data storage function.

[0153] Specifically, storage module 23 can provide data storage of no less than 128MB, which can be used to store the operating data, status data, etc. of the terminal power supply equipment.

[0154] In this embodiment, the terminal power supply device 10 includes measuring components 11, a smoke sensor 12, a protocol compatibility module 13, a flame sensor 14, a lithium battery pack 15, a power management module 16, a control module 17, an LCD screen 18, a data interface 19, a protection module 20, a status indicator light 21, a square fire extinguishing module 22, and a storage module 23. The terminal power supply device 10 also includes a terminal power supply device housing 25, wherein the measuring components 11, the protocol compatibility module 13, the lithium battery pack 15, the power management module 16, the control module 17, the LCD screen 18, the data interface 19, the protection module 20, and the storage module 23 are installed inside the terminal power supply device housing 25. The terminal power supply device 10 also includes a metal handle 24, which can be used to lift or pull the terminal power supply device; the metal handle 24 is installed on the terminal power supply device housing 25.

[0155] For example, Figure 3 This is a front view of a terminal power supply device provided in Embodiment 2 of the present invention; as shown Figure 3 As shown, the terminal power supply device includes an LCD screen, a metal handle, a charging / discharging socket, and status indicator lights. Figure 4 This is a rear view of a terminal power supply device provided in Embodiment 2 of the present invention; as shown Figure 4 As shown, the terminal power supply device includes a switch button and a data interface, where "ON" indicates that the terminal power supply device is turned on and "OFF" indicates that the terminal power supply device is turned off.

[0156] Optionally, the square fire extinguishing module 22 is specifically used for:

[0157] An activation signal is generated based on the smoke and open flame information monitored by the smoke sensor 12 and the flame sensor 14.

[0158] The square fire extinguishing module 22 is activated based on the activation signal and sprays carbon dioxide to achieve the fire extinguishing function.

[0159] Specifically, when the smoke sensor 12 detects that the smoke concentration in the terminal power equipment exceeds a preset threshold, the smoke sensor 12 will send an activation signal to the square fire extinguishing module 22; when the flame sensor 14 detects the characteristic spectrum of the flame (a spectrum of a specific wavelength), the flame sensor 14 will send an activation signal to the square fire extinguishing module 22. The square fire extinguishing module 22 usually combines the activation signals from the flame sensor 14 and the smoke sensor 12 for comprehensive judgment. Only when both sensors simultaneously detect signs of fire and send activation signals will the square fire extinguishing module 22 be triggered to spray carbon dioxide for fire extinguishing.

[0160] In this embodiment, the smoke and flame information monitored by the smoke sensor 12 and the flame sensor 14 are used to generate an activation signal; the square fire extinguishing module 22 is activated based on the activation signal and sprays carbon dioxide to achieve the fire extinguishing function. This can effectively solve the safety problems caused by the power distribution automation terminal losing protection due to the power supply equipment underpowered abnormality and spontaneous combustion, protect equipment assets from loss, and improve the reliability and safety stability of the power distribution network.

Figure 5 As shown, a terminal power device determination system 100 provided in this embodiment of the invention includes: a data query module 110, a status analysis module 120, and an operation and maintenance early warning module 130;

[0163] The data query module 110 is used to query the operating data of the terminal power supply and send it to the status analysis module;

[0164] Specifically, the data query module 110 can query information such as voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information, smoke and open flame information, and operating status of the terminal power supply equipment according to a user-defined time period. The user-defined time period allows the user to set the start and end dates of the query based on actual needs.

[0165] The status analysis module 120 is used to determine the operating status of the terminal power supply device based on the received operating data of the terminal power supply device, and send it to the operation and maintenance early warning module.

[0166] Specifically, the status analysis module 120 can update the abnormal flag bit and / or the protocol incompatibility flag bit according to the voltage, current, temperature, remaining capacity, internal resistance, protocol compatibility information and smoke and open flame information of the terminal power supply device, and determine the operating status of the terminal power supply device based on the updated abnormal flag bit and the updated protocol incompatibility flag bit.

[0167] The operation and maintenance early warning module 130 is used to generate operation and maintenance early warning information based on the received operating status of the terminal power equipment. The operation and maintenance early warning information includes operation and maintenance location, terminal information, abnormal operation information, and operation and maintenance measures.

[0168] Specifically, if the terminal power supply equipment is operating normally, the maintenance early warning module 130 may not need to operate. If the terminal power supply equipment is operating abnormally, incompatible with protocols, or operating abnormally and incompatible with protocols, the maintenance early warning module 130 can automatically generate corresponding maintenance early warning information based on the operating status and the corresponding abnormal information. The abnormal information may refer to stored voltage abnormality information, current abnormality information, etc. This maintenance early warning information is pre-set and corresponds to the abnormal information. The maintenance early warning information specifically includes the maintenance location, distribution automation terminal information, operational abnormality information, and maintenance measures.

[0169] In this embodiment, the terminal power supply equipment status determination system 100 queries the operating data of the terminal power supply equipment through the data query module 110 and sends it to the status analysis module. Based on the received operating data of the terminal power supply equipment, the status analysis module determines the operating status of the terminal power supply equipment, effectively saving the status detection time of the terminal power supply equipment. The system then sends the data to the operation and maintenance early warning module. Based on the received operating status of the terminal power supply equipment, the operation and maintenance early warning module automatically generates corresponding operation and maintenance early warning information, reducing the operation and maintenance pressure on staff and further improving the reliability and safety stability of the power distribution network.

[0172] Specifically, managing the devices in the terminal power supply equipment includes: inputting and exporting basic information of the terminal power supply equipment, and adding or deleting electronic components (such as sensors) in the terminal power supply equipment.

[0173] The mode switching module 150 is used to switch the corresponding terminal mode according to different terminal types.

[0174] Among them, the different terminal types include feeder automation terminal equipment (FTU) and fully insulated circuit breaker cabinet automation terminal equipment (DTU), and the corresponding terminal modes are FTU mode and DTU mode.

[0175] Specifically, when the terminal mode is switched to FTU mode, the user can send control signals to the terminal power supply equipment through the power grid company's distribution automation master station system (the terminal power supply equipment status determination system is a subsystem of the power grid company's distribution automation master station system). The power management module in the terminal power supply equipment controls the lithium battery pack to output a 24-volt DC voltage based on this control signal. When the terminal mode is switched to DTU mode, the user can send control signals to the terminal power supply equipment through the power grid company's distribution automation master station system. The power management module in the terminal power supply equipment controls the lithium battery pack to output a 48-volt DC voltage based on this control signal.

[0176] The protocol compatibility module 160 is used to be compatible with terminal protocols from different manufacturers;
