Description

Technical Field

[0001] The present invention relates to the field of power distribution cabinet monitoring, and in particular to a monitoring system, method and storage medium for a power distribution cabinet. Background Art

[0002] In the field of distribution network automation, distribution network automation terminals are the core components for realizing intelligent control and remote communication. Distribution network automation terminals are responsible for controlling the automation switches and transmitting data to the remote distribution network master station to realize functions such as telemetry, telesignaling, remote control, and remote adjustment, and perform operations such as protection tripping and reclosing when necessary. However, the existing technology has the following problems:

[0003] (1) Information sampling is not comprehensive: The online monitoring of the distribution network automation terminal and the signals sent to the remote distribution network master station are mainly concentrated on the operating status of the switch body and the terminal program. This monitoring ignores the input and output status of the air switch and the hard pressure plate on the distribution network automation terminal operation panel. As a result, even if the switch body and the terminal program are operating normally, the necessary opening and closing actions cannot be performed due to the failure of the key air switch or hard pressure plate to be put into operation, resulting in a delay in the sending of the early warning signal and the inability to timely repair the distribution network automation terminal;

[0004] (2) Poor environmental adaptability: The distribution network automation terminal works outdoors and faces harsh environmental conditions such as high temperature and heavy rain. However, the existing technology does not monitor the opening and closing of the terminal cabinet door, internal water ingress, temperature and humidity during the detection of the distribution network automation terminal, which causes the distribution network automation terminal to malfunction in bad weather.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0043] The above environmental information is used to characterize the temperature information, temperature and humidity information, water inflow information and cabinet door opening and closing status of the target distribution cabinet.

[0044] The above equipment status is used to characterize the working status of the hard pressure plate and the air switch in the target distribution cabinet.

[0045] Specifically, the monitoring information collection module is used to collect the environmental information and equipment status of the target distribution cabinet.

[0047] The above analysis results are used to indicate whether the target power distribution cabinet is in an abnormal state.

[0048] Specifically, the monitoring information analysis module is used to perform abnormal analysis on the environmental information to determine whether the current environment of the target distribution cabinet is abnormal, and the device status information is analyzed abnormally to determine whether the equipment in the target distribution cabinet is in an abnormal working state. When the current environment of the target distribution cabinet is abnormal, or the equipment in the target distribution cabinet is in an abnormal working state, it is determined that the target distribution cabinet is in an abnormal state; when the current environment of the target distribution cabinet is not abnormal, and the equipment in the target distribution cabinet is not in an abnormal working state, it is determined that the target distribution cabinet is not in an abnormal state.

[0049] The early warning module 103 has an input end connected to the output end of the monitoring information analysis module, and is used to generate early warning information when it is determined that the monitoring information is abnormal according to the analysis result.

[0050] Specifically, when the monitoring information is determined to be abnormal based on the analysis results, the early warning module generates early warning information. On the one hand, an early warning signal is generated based on the early warning information to remind the staff to check, and on the other hand, the early warning module sends the early warning information to the distribution network master station. After receiving the early warning information, the distribution network master station further analyzes and processes it. For example, it issues a fault notification, dispatches maintenance personnel, or automatically executes certain control strategies.

[0051] Specifically, the monitoring system of the distribution cabinet also includes a controller 104, which is connected to a monitoring information acquisition module 101, a monitoring information analysis module 102, and an early warning module 103. The controller 104 controls the monitoring information acquisition module 101 to collect monitoring information in the target distribution cabinet, and the controller 104 can control the monitoring information analysis module 102 to perform abnormal analysis on the monitoring information to obtain analysis results. Finally, when the controller 104 controls the early warning module 103 to determine that an abnormality occurs in the monitoring information based on the analysis results, early warning information is generated, and the target distribution cabinet can be monitored in real time to timely warn of potential risks and faults.

It is easy to notice that the monitoring information in the target distribution cabinet can be quickly and comprehensively collected by using the monitoring information acquisition module, and the monitoring information analysis module accurately judges whether the detection information is in an abnormal state. Finally, the early warning module is used to generate early warning information and report the early warning information in a timely and rapid manner, thereby achieving the purpose of comprehensively utilizing environmental information and equipment status information to identify the operating status of the distribution cabinet, and timely warning of potential risks and faults, thereby achieving the technical effect of improving the reliability and safety of the distribution system, and further solving the technical problems of incomplete monitoring and untimely early warning caused by single monitoring information in related technologies.

The input end of the power module is connected to the DC power supply of the distribution network automation terminal to convert DC 24V or 48V into DC 3.3V. The power module is built based on the LM2596S-3.3 / TR chip (U2). U2 includes a VIN pin (1), an OUTPUT pin (2), a GND pin (3), a FB pin (4), an ON#OFF pin (5) and a GND pin (6). The VIN pin (1) is an input pin for receiving a high voltage input. The OUTPUT pin (2) is an output pin that provides a stable 3.3V output voltage. The GND pin (3) and the GND pin (6) are ground pins for connecting the negative pole of the circuit. The FB pin (4) is a feedback pin for adjusting the output voltage. By connecting a voltage divider to the output and the ground, the output voltage can be controlled. The ON#OFF pin (5) is a switch control pin for controlling the switch of U2.

The rectifier diode 1N4007 (U3) is used to protect the circuit from reverse voltage. When the input voltage is applied to the VIN pin of U2, the PWM controller inside U2 starts working and converts the input voltage into a pulse width modulated output. The output voltage is connected to the second capacitor C21 after passing through the inductor L1 and is finally provided to the load. A small part of the output voltage is sent back to the FB pin of U2. The voltage comparator inside U2 compares the voltage of the FB pin with the internal reference voltage. If the voltage of the FB pin is higher than the reference voltage, the PWM duty cycle decreases and the output voltage decreases; conversely, if the voltage of the FB pin is lower than the reference voltage, the PWM duty cycle increases and the output voltage increases.

VBAT(1) is used to provide an independent battery power supply to the RTC (real-time clock) and backup registers. This power supply can still maintain the contents of the RTC and backup registers after the main power supply (VDD or VDDA) is turned off. PD0-OSC_IN(5) is the input pin of the external crystal oscillator. The external crystal oscillator signal is input into the microcontroller through PD0 to provide a clock signal. PD0-OSC_IN(6) is the output pin of the external crystal oscillator, which is used to output the clock signal. Reset pin: NRST(7) is the reset pin, which is valid at low level. VSSA(8) is the analog ground pin, which is used to provide a reference ground for the analog circuit of U1 and is separated from the digital ground (VSS) to reduce noise interference between the analog and digital circuits. The power pins include: VDD_1 (24), VDD_2 (36), VDD_3 (48), which are the operating voltage pins of the chip and provide 3.3V power supply; VDDA (9), which is the analog power pin, usually the same as VDD. VSS_1 (23), VSS_2 (35), VSS_3 (47) are ground pins, connected to ground.

When the relay is not activated, these two pins are in a closed state; when the relay is activated, these two pins are disconnected to turn off the circuit; pins 1 and 16 are coil pins. When a suitable voltage is applied between these two pins, the electromagnetic coil will generate a magnetic field to attract the iron core inside the relay, thereby closing the normally open contact and disconnecting the normally closed contact (or vice versa), thereby switching the circuit.

The early warning module can respond to the level signal output by the single-chip microcomputer in real time through the cooperation of the transistor and the relay. When the operating state of the distribution cabinet is detected to be abnormal, the single-chip microcomputer immediately outputs a high-level signal to trigger the transistor to turn on, thereby activating the relay, turning on the early warning signal light, and sending the early warning information to the distribution network master station.

[0089] Figure 6 is a flow chart of a monitoring method for a power distribution cabinet according to one embodiment of the present invention, which is applied to a monitoring system for a power distribution cabinet, such as Figure 6 As shown, the method comprises the following steps:

[0090] Step S60, collecting monitoring information in the target power distribution cabinet, wherein the monitoring information includes: environmental information and equipment status information;

[0091] In step S60, the above environmental information is used to characterize the temperature information of components in the target power distribution cabinet, the temperature and humidity information in the target power distribution cabinet, the water inflow information and the cabinet door opening and closing status.

[0092] The above equipment status is used to characterize the working status of the hard pressure plate and the air switch in the target distribution cabinet.

[0093] Step S62, performing abnormality analysis on the environmental information to obtain a first analysis result, wherein the first analysis result is used to determine whether the current environment of the target power distribution cabinet is abnormal;

[0094] Specifically, the temperature of the components in the target distribution cabinet collected is judged. If the temperature of the components in the target distribution cabinet exceeds the preset temperature threshold, the first analysis result indicates that the current environment of the target distribution cabinet is in an abnormal state. For example, the temperature of the core components such as the power module, protection unit, and battery of the distribution network automation terminal is detected to determine the operating status of the core components. The collected temperature and humidity are judged. If the temperature and humidity of the target distribution cabinet exceeds the preset temperature and humidity threshold, the first analysis result indicates that the current environment of the target distribution cabinet is in an abnormal state. The collected water inflow in the cabinet is judged. If the water inflow of the target distribution cabinet exceeds the preset water inflow threshold, the first analysis result indicates that the current environment of the target distribution cabinet is in an abnormal state. According to the light intensity in the target distribution network cabinet, the opening and closing state of the target distribution network cabinets is judged. If the cabinet door of the target distribution cabinet is in an open state, the first analysis result indicates that the current environment of the target distribution cabinet is in an abnormal state.

[0095] Step S64, performing an abnormality analysis on the device status information to obtain a second analysis result, wherein the second analysis result is used to determine whether the device in the target power distribution cabinet is in an abnormal state;

[0096] Specifically, an abnormal analysis is performed on the equipment status information to determine whether the equipment in the target distribution cabinet is in an abnormal state. If the equipment in the distribution cabinet is in an abnormal state, it means that the hard pressure plate or the air switch is in the exit state. If the equipment in the distribution cabinet is in an abnormal state, it means that the hard pressure plate or the air switch is in the engaged state.

[0097] Step S66, determining a target analysis result based on the first analysis result and the second analysis result, wherein the target analysis result is used to determine whether the target power distribution cabinet is in an abnormal working state;

[0098] Specifically, it is determined whether the target power distribution cabinet is in an abnormal working state according to the first analysis result and the second analysis result. If the first analysis result indicates that the hard pressure plate or air switch in the power distribution cabinet is in an abnormal state, or the second analysis result indicates that the current environment of the target power distribution cabinet is in an abnormal state, then the target analysis result indicates that the target power distribution cabinet is in an abnormal working state. If the first analysis result indicates that the hard pressure plate or air switch in the power distribution cabinet is in a normal working state, and the second analysis result indicates that the current environment of the target power distribution cabinet is in a normal state, then the target analysis result indicates that the target power distribution cabinet is in a normal working state.

On the one hand, an early warning signal is generated based on the early warning information to remind the staff to check. For example, the early warning indicator light is in a flashing state. On the other hand, the early warning information is sent to the distribution network master station. After receiving the early warning information, the distribution network master station further analyzes and processes it. For example, a fault notification is issued, maintenance personnel are dispatched, or certain control strategies are automatically executed.

[0101] Based on the above steps S60 to S68, the monitoring information in the target distribution cabinet is collected, and the environmental information is analyzed for abnormalities to obtain a first analysis result, and the equipment status information is analyzed for abnormalities to obtain a second analysis result. Finally, the target analysis result is determined based on the first analysis result and the second analysis result, and in response to determining that the target distribution cabinet is in an abnormal state according to the target analysis result, early warning information is generated, thereby achieving the purpose of comprehensively utilizing environmental information and equipment status information to identify the operating status of the distribution cabinet, and timely warning of potential risks and faults, thereby achieving the technical effect of improving the reliability and safety of the distribution system, and further solving the technical problems of incomplete monitoring and untimely early warning caused by single monitoring information in related technologies.

[0104] Specifically, when the hard pressure plate in the equipment status information is in the exit state or at least one air switch is in the exit state, the second analysis result is determined to be that the equipment in the target distribution cabinet is in an abnormal state; when the hard pressure plate in the equipment status information is in the exit state and all air switches are in the engaged state, the second analysis result is determined to be that the equipment in the target distribution cabinet is not in an abnormal state.

[0105] Based on the above step S641, in response to the equipment status information that the hard pressure plate is in the exit state or at least one air switch is in the exit state, the second analysis result is determined to be that the equipment in the target distribution cabinet is in an abnormal state, which can accurately judge the operating status of the distribution cabinet and promptly discover potential risks and faults.

[0106] Optionally, in step S66, determining a target analysis result based on the first analysis result and the second analysis result includes:

[0107] Step S661, in response to determining that the current environment of the target distribution cabinet is abnormal based on the first analysis result, or determining that the equipment in the target distribution cabinet is in an abnormal working state based on the second analysis result, determine that the target analysis result is that the target distribution cabinet is in an abnormal state.

[0108] Specifically, if the first analysis result indicates that the hard pressure plate or air switch in the distribution cabinet is in the exit state, or the second analysis result indicates that the current environment of the target distribution cabinet is in an abnormal state, then the target analysis result indicates that the target distribution cabinet is in an abnormal working state, wherein the current environment of the target distribution cabinet is in an abnormal state including that the temperature of the components in the target distribution cabinet exceeds the preset temperature threshold, the temperature and humidity of the target distribution cabinet exceed the preset temperature and humidity thresholds, the water inlet of the target distribution cabinet exceeds the preset water inlet threshold, and the door of the target distribution cabinet is in an open state.

[0109] Specifically, if the first analysis result shows that the hard pressure plate or air switch in the distribution cabinet is in the on state, and the second analysis result shows that the current environment of the target distribution cabinet is normal, then the target analysis result indicates that the target distribution cabinet is in normal working state.

[0110] Based on the above step S661, in response to determining that the current environment of the target distribution cabinet is abnormal based on the first analysis result, or determining that the equipment in the target distribution cabinet is in an abnormal working state based on the second analysis result, the target analysis result is determined to be that the target distribution cabinet is in an abnormal state, thereby achieving the purpose of comprehensively utilizing environmental information and equipment status information to identify the operating status of the distribution cabinet, and timely warning of potential risks and faults, thereby achieving the technical effect of improving the reliability and safety of the distribution system, and further solving the technical problems of incomplete monitoring and untimely warning caused by single monitoring information in related technologies.
