[0034] To help those skilled in the art better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of this solution, not all of it. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this solution.

[0035] Throughout the specification, claims, and accompanying figures of this solution, the term "including" and any variations thereof mean "including, but not limited to," and are intended to cover non-exclusive inclusions and are not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.

[0036] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:

[0037] Figure 1 This is a schematic diagram of the structure of a power equipment monitoring system provided by an embodiment of the present disclosure. Figure 1The power equipment monitoring system includes: a temperature detection module, a switch module, a main control module, a first timing module and a second timing module; the first end of the switch module is used to connect to the power supply, the second end of the switch module is connected to the power supply end of the temperature detection module, and the temperature detection module is connected to the main control module; the control ends of the switch module, the first timing module and the second timing module are all connected to the main control module, and the output ends of the first timing module and the second timing module are all connected to the control end of the switch module; the temperature detection module is configured to detect the operating temperature of the power equipment in the power equipment room, the first timing module is configured to control the switch module based on a first set time, and the second timing module is configured to control the switch module based on a second set time, and the first set time is greater than the second set time.

[0038] In this embodiment, the temperature detection module is used to detect the operating temperature of the power equipment in the power equipment room and transmit the temperature information to the main control module. By continuously monitoring the temperature, it is possible to promptly detect whether the power equipment has any abnormal conditions such as overheating.

[0039] The switch module's first end is connected to a power source, and its second end is connected to the power supply of the temperature detection module. Its on / off state directly determines whether the temperature detection module can obtain power. The switch module's control end is connected to the main control module, the first timing module, and the second timing module, respectively, switching its on / off state based on control signals from these modules. This allows precise control of the power supply to the temperature detection module through different control signals.

[0040] The temperature detection module in this embodiment has three working modes. The temperature detection frequency of the power equipment is different in different working modes, so as to achieve a balance between energy saving and efficient monitoring.

[0041] When the operating temperature of the power equipment is less than a first preset value, it indicates that the temperature of the power equipment is within a relatively low safety range. At this point, the main control module sends a control instruction to the first timing module, which controls the switch module based on the first set time. This means that the temperature detection module will perform temperature checks on the power equipment at longer intervals. Because when the temperature is low, the likelihood of equipment anomalies is lower, and frequent checks are unnecessary, thus saving energy.

[0042] When the operating temperature of the power equipment is greater than the first preset value and less than or equal to the second preset value, it indicates that the power equipment temperature has increased but remains within an acceptable range. The main control module sends a control instruction to the second timing module, which controls the switch module based on the second set time. Due to the increased risk caused by the rising temperature, the temperature detection module's detection frequency is higher than when the temperature is lower, but still lower than when the temperature is too high.

[0043] When the operating temperature of the electrical equipment exceeds a second preset value, it indicates that the equipment is in a dangerously high-temperature state. The main control module can directly send a control instruction to the switch module, which connects the power supply to the power supply terminal of the temperature detection module. The temperature detection module then enters a state of continuous temperature detection. This ensures real-time monitoring of high-temperature equipment, allowing timely measures to prevent equipment damage.

[0044] For example, in a large factory's power equipment room, the temperature detection module uses a high-precision infrared temperature sensor, capable of contactlessly measuring the surface temperature of power equipment. The sensor communicates with the main control module via a wired connection. The switch module uses an intelligent relay, which quickly responds to control signals and stably controls power on and off. The main control module utilizes an industrial-grade microcontroller with powerful computing and control capabilities, capable of processing temperature data and issuing control commands in real time. The first and second timing modules utilize programmable timer chips, allowing for different time settings based on actual needs.

[0045] The first preset value is set to 40° C., and the first set time is set to detect the temperature once every 30 minutes.

[0046] The second preset value is set to 60° C., and the second set time is set to detect the temperature once every 5 minutes.

[0047] After the system is started, the temperature detection module begins to continuously monitor the temperature of the power equipment and transmits the temperature data to the main control module.

[0048] When the temperature of the power equipment is lower than 40°C, the main control module sends a control instruction to the first timing module. The first timing module controls the switch module at a time interval of every 30 minutes, so that the temperature detection module performs a temperature detection on the power equipment every 30 minutes.

[0049] When the temperature of the power equipment rises to greater than 40°C and less than or equal to 60°C, the main control module sends a control instruction to the second timing module. The second timing module controls the switch module at intervals of every 5 minutes, and the temperature detection module performs a temperature detection on the power equipment every 5 minutes.

[0050] When the temperature of electrical equipment exceeds 60°C, the main control module sends a control command directly to the switch module, which immediately connects the power supply to the temperature detection module, and the temperature detection module enters a continuous temperature detection state. At this time, the main control module can also issue an alarm signal to notify personnel to promptly deal with the high-temperature equipment.

[0051] As can be seen from the above, this embodiment can automatically adjust the frequency of temperature monitoring based on the operating temperature of the power equipment. This not only ensures that unnecessary energy consumption is reduced when the temperature is low, but also promptly increases the monitoring frequency when the temperature rises to prevent potential risks. In particular, when the temperature of the power equipment is too high, this embodiment can immediately initiate continuous temperature monitoring, ensuring real-time monitoring of high-temperature equipment and effectively preventing equipment damage due to overheating. This achieves comprehensive, accurate, and efficient monitoring of the temperature of power equipment, providing a strong guarantee for the safe operation of power equipment. This not only improves the management efficiency of power equipment, but also reduces operation and maintenance costs.

[0052] like Figure 1 As shown, in one embodiment of the present disclosure, it also includes: a temperature control module; the temperature control module is connected to the main control module; the temperature control module is configured to cool the power equipment.

[0053] In this embodiment, upon receiving a cooling command from the main control module, the temperature control module activates appropriate cooling devices or mechanisms (such as fans, cooling water systems, and refrigerant injection) to cool the power equipment. This cooling operation can continue until the operating temperature of the power equipment falls within a safe range, or until the main control module issues a command to stop cooling.

[0054] For example, in a large factory's electrical equipment room, when the operating temperature of a piece of electrical equipment exceeds a preset second preset value, the main control module not only activates the temperature detection module's continuous temperature detection function but also sends a cooling instruction to the temperature control module. Upon receiving the instruction, the temperature control module activates the fan system connected to the electrical equipment to force air cooling on the equipment. Simultaneously, the main control module dynamically adjusts the fan speed based on the real-time temperature information provided by the temperature detection module to ensure cooling effectiveness and avoid overcooling. When the equipment's operating temperature drops to a safe range, the main control module sends instructions to the switch module and the temperature control module, respectively reducing the temperature detection module's detection frequency and stopping the fan.

[0055] From the above, it can be concluded that by adding a temperature control module, the power equipment monitoring system in this embodiment can not only accurately monitor and efficiently manage the temperature of the power equipment, but also automatically perform cooling operations according to the temperature conditions, thereby further improving the safety and reliability of the power equipment.

[0056] like Figure 1 As shown, in one embodiment of the present disclosure, it also includes: a fan control module; the fan control module is connected to the main control module; the fan control module is configured to control the uniformity of the indoor temperature of the power equipment.

[0057] In this embodiment, the fan control module is connected to the main control module. Its primary function is to control the air flow within the power equipment room, thereby achieving uniform indoor temperature. By properly controlling the fan's operating state, localized overheating or overcooling can be avoided, improving the stability and reliability of power equipment operation.

[0058] Exemplarily, the temperature detection module monitors the temperature of various locations in the power equipment room in real time, and transmits the temperature data to the main control module. The main control module analyzes the temperature data and determines the uniformity of the indoor temperature. If it is found that the temperature in some areas is significantly higher or lower than that in other areas, and the temperature difference exceeds the set uniformity threshold, the main control module sends a control instruction to the fan control module. The fan control module can adjust the speed and wind direction of the fan according to the instruction. For example, if the temperature in a corner is too high, the speed of the nearby fan can be increased, and the wind direction can be adjusted to aim at the area to promote air flow, take away the heat, and make the temperature tend to be uniform. When the operating temperature of the power equipment exceeds the preset value, the main control module, on the one hand, starts the temperature control module to cool down, and on the other hand, combines with the fan control module to speed up the dissipation of heat and improve the cooling effect.

[0059] It can be concluded from the above that this embodiment can effectively control the uniformity of the indoor temperature of the power equipment through the fan control module, thereby providing a more stable operating environment for the power equipment.

[0060] like Figure 2 As shown, in one embodiment of the present disclosure, it also includes: a power detection module, a power switching module and a battery; the first end of the power detection module is used to connect to the power supply, and the second end of the power detection module is connected to the main control module; the first end of the power switching module is used to connect to the power supply, the second end of the power switching module is connected to the battery, and the third end of the power switching module is connected to the first end of the switch module; the power detection module is configured to detect the power supply voltage.

[0061] In this embodiment, the power detection module continuously monitors the voltage of the main power supply and sends the voltage information to the main control module. Based on the received voltage information, the main control module determines whether the main power supply is stable and sufficient to supply power to the monitoring system. When the main power supply voltage is normal and stable, the power switching module provides the power of the main power supply to the switch module, thereby supplying power to the entire monitoring system. When the main power supply voltage is unstable or lower than the preset threshold, the main control module sends an instruction to the power switching module to switch to the battery power supply mode. After receiving the instruction, the power switching module immediately cuts off the connection between the main power supply and the switch module, and provides the battery power to the switch module to ensure that the monitoring system continues to operate. After the main power supply resumes stable power supply, the main control module will send an instruction to the power switching module again to switch back to the main power supply mode.

[0062] For example, assume that in a substation with a complex working environment, the main power supply is unstable due to environmental influences. To ensure the continuous operation of the power equipment monitoring system, the system is equipped with a power detection module, a power switching module, and a battery. When the main power supply is interrupted, the power detection module immediately detects the voltage anomaly and sends the information to the main control module. The main control module responds quickly and controls the power switching module to switch to battery power mode. The battery then provides power to the monitoring system, ensuring that the system continues to monitor the working status of the power equipment. When the main power supply is restored, the main control module again controls the power switching module to switch back to the main power supply mode and recharge the battery for the next use.

[0063] As can be seen from the above, through the coordinated operation of the power detection module, power switching module, and battery, the power equipment monitoring system of this embodiment can automatically switch to the backup power supply when the main power supply is unstable or interrupted, ensuring continuous system operation. This not only improves system reliability but also avoids monitoring interruptions and data loss caused by power supply problems, thereby ensuring the safe operation of power equipment.

[0064] like Figure 2 As shown, in one embodiment of the present disclosure, it also includes: a charging module; the first end of the charging module is used to connect to the power supply, and the second end of the charging module is connected to the battery.

[0065] In this embodiment, the charging module's first end is connected to a power source, and its second end is connected to a battery. Its primary function is to charge the battery when the power source is functioning normally, ensuring that the battery is always fully or nearly fully charged, ready to provide emergency power to the power equipment monitoring system in the event of a power failure. When the power detection module detects that the power source voltage is normal, the charging module begins operating, transferring power from the power source to the battery for charging. The charging process can be intelligently controlled based on the battery type and characteristics, employing various charging modes, such as constant current charging, constant voltage charging, or trickle charging, to protect the battery and extend its lifespan.

[0066] From the above, it can be concluded that the charging module in the power equipment monitoring system can provide reliable charging function for the battery when the power supply is normal, ensuring that the battery can provide emergency power for the system when needed, thereby improving the stability and reliability of the system.

[0067] like Figure 2 As shown, in one embodiment of the present disclosure, the charging module includes an overcharge protection circuit and an over-discharge protection circuit; the overcharge protection circuit is configured to protect the battery from overcharge, and the over-discharge protection circuit is configured to protect the battery from over-discharge.

[0068] In this embodiment, while the charging module is charging the battery, the overcharge protection circuit continuously monitors the battery voltage. If the battery voltage rises to the set overcharge voltage threshold, the overcharge protection circuit immediately takes action, cutting off the charging current to prevent the battery from overcharging. Overcharging can cause the battery to heat up, swell, or even damage, which can lead to safety accidents in serious cases. By promptly cutting off the charging current, the overcharge protection circuit protects the battery and extends its service life.

[0069] When the battery is powering the power equipment monitoring system, the over-discharge protection circuit monitors the battery voltage. If the battery voltage drops below the set over-discharge voltage threshold, the over-discharge protection circuit activates, shutting off the battery's discharge circuit to prevent over-discharge. Over-discharge can cause irreversible damage to the battery, reducing its capacity and performance. The over-discharge protection circuit protects the battery by promptly shutting off the discharge circuit, ensuring that the battery can function normally during the next charge.

[0070] It can be concluded from the above that the overcharge protection circuit and over-discharge protection circuit of the charging module in this embodiment can effectively protect the battery and improve the reliability and safety of the system.

[0071] like Figure 2 As shown, in one embodiment of the present disclosure, it further includes: a communication module; the main control module is connected to the monitoring terminal through the communication module.

[0072] In this embodiment, the communication module serves as a bridge between the main control module and the monitoring terminal. Through the communication module, the main control module can transmit data such as power equipment temperature information obtained by the temperature detection module, power supply voltage information detected by the power detection module, battery charge status, and the operating status of each module to the monitoring terminal. The monitoring terminal can also send control commands to the main control module through the communication module, enabling remote control and management of the power equipment monitoring system.

[0073] For example, consider a power equipment monitoring system in a large factory. The main control module is connected to a monitoring terminal via a wired communication module (such as Ethernet). When an abnormality occurs in the factory's power equipment, the main control module immediately collects the abnormality data and transmits it to the monitoring terminal via the communication module. After receiving the data, the monitoring terminal displays the name, location, and type of abnormality of the abnormal device on the interface and issues an alarm. Users can view detailed information through the monitoring terminal interface and send control commands to the main control module, such as shutting down the abnormal device or activating a backup device. The real-time data transmission function of the communication module allows users to quickly understand the equipment status and take appropriate control measures to ensure the safe operation of the factory.

[0074] As can be seen from the above, this embodiment, by adding a communication module, achieves data connection and transmission between the main control module and the monitoring terminal, improving the system's monitoring capabilities and response speed. At the same time, the flexible configuration and scalability of the communication module also enable the system to be flexibly adjusted and optimized according to actual needs.

[0075] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
