Description

Technical Field

[0001] The present application relates to the field of power equipment monitoring, and in particular to a substation switch cabinet box environment monitoring and control system. Background Art

[0002] The function of the outdoor switch cabinet box of the substation is to transfer the status, secondary current and secondary voltage of the transformer, circuit breaker, disconnector, current transformer and voltage transformer to the measurement and control and protection devices in the protection room. On the other hand, it also provides the corresponding power mechanism and power supply for the operation of the primary equipment. In the normal operation of the substation equipment, the switch cabinet and the mechanism box play a vital role. The factors that affect its operation status are mainly the following two points: First, the influence of the natural environment. In the rainy summer and cold winter, the door of the switch cabinet box installed outdoors is not closed tightly, which makes the internal secondary wiring prone to moisture and mildew, affecting the electrical insulation performance; fine sand and dust enter the mechanism box or terminal box to form a dust collection effect, affecting the normal function of the control equipment; if the secondary wiring is corroded and damaged, it may cause the current loop terminal to heat up, causing the switch cabinet to catch fire, and the protection to refuse to operate or malfunction. Second, if the terminal block, the opening and closing coil, etc. are abnormally heated due to accidental contact or misoperation by personnel during maintenance work, the operation and maintenance personnel cannot discover the abnormal phenomenon in time. If the heating continues or even the arc is generated by sparking and burning, it will seriously threaten the safe operation of the power grid.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The core of this application is to provide a substation switch cabinet box environment monitoring and control system.

[0040] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The function of the outdoor switch cabinet box of the substation is to transfer the status, secondary current and secondary voltage of the transformer, circuit breaker, disconnector, current transformer and voltage transformer to the measurement and control and protection devices in the protection room. On the other hand, it also provides the corresponding power mechanism and power supply for the operation of the primary equipment. In the normal operation of the substation equipment, the switch cabinet and the mechanism box play a vital role. The factors that affect its operation status are mainly the following two points: First, the influence of the natural environment. In the rainy summer and cold winter, the door of the switch cabinet box installed outdoors is not closed tightly, which makes the internal secondary wiring prone to moisture and mildew, affecting the electrical insulation performance; fine sand and dust enter the mechanism box or terminal box to form a dust collection effect, affecting the normal function of the control equipment; if the secondary wiring is corroded and damaged, it may cause the current loop terminal to heat up, causing the switch cabinet to catch fire, and the protection to refuse to operate or malfunction. Second, if the terminal block, the opening and closing coil, etc. are abnormally heated due to accidental contact or misoperation by personnel during maintenance work, the operation and maintenance personnel cannot discover the abnormal phenomenon in time. If the heating continues or even the arc is generated by sparking and burning, it will seriously threaten the safe operation of the power grid.

[0042] In order to solve the above problems, this embodiment provides a substation switch cabinet box environment monitoring and control system. Figure 1 A schematic diagram of a substation switch cabinet box environment monitoring and control system provided in an embodiment of the present application, such as Figure 1 As shown, including:

[0043] A temperature and humidity sensor 11, an ultrasonic sensor 12, an infrared sensor 13, a controller 14, a temperature and humidity adjustment device 15, and a sound device 16 are arranged in the switch cabinet of the substation;

[0044] The temperature and humidity sensor 11 monitors the temperature and humidity data inside the box in real time and sends the temperature and humidity data to the controller 14;

[0045] The ultrasonic sensor 12 detects the state of the door of the switch cabinet through ultrasonic signals and sends the state of the door to the controller 14;

[0047] The controller 14 controls the temperature and humidity regulating device 15 according to the temperature and humidity data, controls the sound device 16 to emit an expulsion sound according to the infrared data, and records and uploads the state of the box door.

[0048] In this embodiment, the temperature and humidity sensor 11 refers to a device that can monitor and record the temperature and humidity inside the switch cabinet in real time, and can be specifically a sensor that integrates temperature and humidity sensing elements; this sensor is usually made of semiconductor materials and can convert changes in temperature and humidity into electrical signals and send them to the controller 14. The controller 14 controls the temperature and humidity adjustment device 15, such as an air conditioner or a heater, based on these data to maintain a suitable temperature and humidity level. This automatic adjustment mechanism can prevent the insulation performance of electrical equipment from being reduced due to excessive humidity or the overheating of equipment caused by excessive temperature.

[0049] The ultrasonic sensor 12 refers to a device that uses ultrasonic signals to detect the state of the switch cabinet box door, which can be specifically a device including a transmitter and a receiver; the sensor determines whether the box door is closed and the degree of closure by emitting ultrasonic waves and receiving the reflected signals. The ultrasonic sensor 12 sends the box door state information to the controller 14, and the controller 14 can perform corresponding operations based on it, such as issuing an alarm or recording the state, to ensure the safety of the box door.

[0050] The infrared sensor 13 refers to a device that can detect infrared radiation data inside the box, which can be a thermal imager or an infrared camera. This sensor monitors the environment inside the box by capturing infrared radiation emitted by objects, such as detecting the invasion of small animals. The infrared sensor 13 sends the infrared data of the detected small animals to the controller 14, and the controller 14 controls the sound device 16 to emit an expulsion sound based on this data to prevent the small animals from causing damage to the inside of the box. This automatic monitoring and expulsion mechanism reduces the need for manual patrols and improves the safety of the system.

[0051] The controller 14 receives data from various sensors and processes them according to preset logic to control corresponding devices.

[0052] The temperature and humidity adjustment device 15 refers to a device for adjusting the temperature and humidity inside the box, which may be an air conditioner, a heater, a dehumidifier or a fan; these devices are automatically turned on or off according to the instructions of the controller 14 to maintain the temperature and humidity inside the box within a suitable range. The selection and configuration of various devices can be optimized according to the actual box size and environmental requirements to achieve the best adjustment effect.

[0053] The sound device 16 refers to a device for emitting expelling sounds, which may be specifically a speaker and an audio signal generator; when the infrared sensor 13 detects a small animal, the controller 14 activates the sound device 16 to emit a sound of a specific frequency to expel the small animal. The controller 14 determines whether to activate the sound device 16 and what sound frequency and volume to select based on the data of the infrared sensor 13.

[0054] The substation switch cabinet box environment monitoring and control system provided by the embodiment of the present application includes: a temperature and humidity sensor 11, an ultrasonic sensor 12, an infrared sensor 13, a controller 14, a temperature and humidity adjustment device 15, and a sound device 16 arranged in the substation switch cabinet box; the temperature and humidity sensor 11 monitors the temperature and humidity data inside the box in real time and sends the temperature and humidity data to the controller 14; the ultrasonic sensor 12 detects the box door state of the switch cabinet box through ultrasonic signals and sends the box door state to the controller 14; the infrared sensor 13 detects the infrared data in the box and sends the infrared data to the controller 14; the controller 14 controls the temperature and humidity adjustment device 15 according to the temperature and humidity data, controls the sound device 16 according to the infrared data to emit an expulsion sound, and records and uploads the box door state. The controller 14 is connected to the temperature and humidity sensor 11 and the temperature and humidity adjustment device 15, realizing real-time data transmission and rapid response, so that the system can automatically adjust the internal environment of the box and maintain suitable working conditions. The controller 14 is connected to the infrared sensor 13 and the sound device 16 in communication, so that the system can detect and handle small animal invasion events in a timely manner. The wired connection between the ultrasonic sensor 12 and the controller 14 ensures accurate monitoring of the box door status, improves the operational safety and maintenance efficiency of the substation switch cabinet, reduces the workload of manual inspections, reduces operation and maintenance costs, and effectively prevents equipment failures caused by environmental factors through automatic monitoring and adjustment.

[0055] Further, in a specific embodiment, in the above-mentioned substation switch cabinet box environment monitoring and control system, the number of temperature and humidity sensors 11 is multiple;

[0056] A plurality of temperature and humidity sensors 11 are arranged in different areas of the switch cabinet of the substation;

[0057] The controller 14 obtains average temperature and humidity data of different areas according to the temperature and humidity data of each temperature and humidity sensor 11, and controls the temperature and humidity adjustment device 15 of the corresponding area according to the average temperature and humidity data.

[0058] In this embodiment, multiple temperature and humidity sensors 11 are installed in each key area of ​​the substation switch cabinet body, and these sensors are responsible for real-time monitoring of the temperature and humidity conditions in their respective areas. Since the substation switch cabinet body may be large and have multiple devices distributed, multiple sensors can ensure more comprehensive monitoring coverage and avoid blind spots.

[0059] Multiple temperature and humidity sensors 11 are distributed in different areas of the switch cabinet body to monitor the temperature and humidity data of each area in real time and send the data to the controller 14. Multiple temperature and humidity sensors 11 can be evenly distributed or specifically set according to the actual environment.

[0060] The controller 14 receives data from all temperature and humidity sensors 11, calculates the average temperature and humidity data of each area, and independently controls the temperature and humidity adjustment device 15 of the corresponding area according to the average temperature and humidity data of each area. Each area is equipped with at least one set of temperature and humidity adjustment devices 15, such as air conditioners, heaters, dehumidifiers or fans.

[0061] By installing multiple temperature and humidity sensors 11 in each area, the system can more accurately monitor and adjust the temperature and humidity inside the cabinet to ensure that the temperature and humidity in each area are maintained at the optimal state. The corresponding temperature and humidity adjustment device 15 can be independently controlled according to the actual temperature and humidity conditions in each area, avoiding energy waste that may be caused by global adjustment. By monitoring the temperature and humidity in each area, the system can promptly detect and deal with local overheating or overhumidity problems to prevent these problems from spreading to the entire cabinet. Maintaining a suitable temperature and humidity environment helps to extend the service life of equipment in the switch cabinet and reduce equipment failures caused by environmental problems.

[0062] Further, in a specific embodiment, in the above-mentioned substation switch cabinet box environment monitoring and control system, the temperature and humidity adjustment device 15 includes a heating device, a cooling device, and a dehumidification device;

[0063] When the temperature data is lower than the preset lower temperature limit, the controller 14 controls the heating device to turn on;

[0064] When the temperature data is higher than the preset temperature lower limit and lower than the preset temperature upper limit, and the humidity data is lower than the preset humidity upper limit, the controller 14 controls the temperature and humidity regulating device 15 to stop working;

[0065] When the temperature data is higher than the preset temperature lower limit and lower than the preset temperature upper limit, and the humidity data is higher than the preset humidity upper limit, the controller 14 controls the dehumidification device to turn on;

[0066] When the temperature data is higher than the preset upper temperature limit, the controller 14 controls the refrigeration equipment to turn on.

[0067] In this embodiment, the temperature and humidity regulating device 15 of the substation switch cabinet box includes heating equipment, cooling equipment and dehumidification equipment. These devices are intelligently controlled by the controller 14 to adjust the internal environment of the box according to real-time temperature and humidity data to adapt to different environmental requirements.

[0068] Figure 2 A schematic diagram of temperature and humidity adjustment provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, when the temperature data is lower than the preset lower temperature limit (0° C.), the controller 14 controls the heating device to turn on to increase the temperature inside the cabinet.

[0069] When the temperature data is higher than the preset upper temperature limit (35° C.), the controller 14 controls the refrigeration device to turn on to reduce the temperature inside the cabinet.

[0070] When the temperature data is higher than the preset temperature lower limit (0°C) and lower than the preset temperature upper limit (35°C), and the humidity data is about the preset humidity upper limit (70%), the controller 14 controls the dehumidification device to turn on to reduce the humidity inside the box.

[0071] Furthermore, a preset optimal temperature and a preset optimal humidity can be set. When the temperature data is higher than the preset temperature lower limit and lower than the preset optimal temperature (25°C), and the humidity data is lower than the preset optimal humidity (65%), the temperature and humidity regulating device 15 is turned off; if the temperature data is lower than the preset temperature upper limit and higher than the preset optimal temperature, and the humidity data is higher than the preset optimal humidity and lower than the preset humidity upper limit, the temperature and humidity regulating device 15 is kept in operation.

[0072] By precisely controlling the temperature and humidity regulating device 15, the system can save energy to the maximum extent while meeting the equipment operation requirements. Maintaining the temperature and humidity inside the box within an appropriate range helps protect the electrical equipment in the switch cabinet and extend its service life. By turning on the dehumidification equipment in time, problems such as reduced insulation performance, rust and mildew of the equipment caused by excessive humidity can be effectively prevented. By turning on the heating or cooling equipment in time, it is possible to prevent equipment startup difficulties due to low temperature or equipment overheating damage due to high temperature.

[0073] Furthermore, in a specific embodiment, in the above-mentioned substation switch cabinet box environment monitoring and control system, the heating equipment includes an air-conditioning heating module and a heating plate; the refrigeration equipment includes an air-conditioning refrigeration module; and the dehumidification equipment includes an air-conditioning dehumidification module and a dehumidifier.

[0074] In this embodiment, the temperature and humidity regulating device 15 of the substation switch cabinet box is composed of a plurality of specialized devices, including an air conditioning heating module, a heating plate, an air conditioning cooling module, an air conditioning dehumidification module and a dehumidifier. These devices can work independently or collaboratively according to the instructions of the controller 14 to adjust the temperature and humidity inside the box.

[0075] The heating device includes an air conditioning heating module and a heating plate. When the temperature data of the air conditioning heating module is lower than the preset lower limit, the controller 14 controls the air conditioning heating module to turn on to increase the temperature inside the box. The heating plate is an auxiliary heating device. The heating plate can be used when the air conditioning heating module is not sufficient to provide sufficient heat, or as a backup when the air conditioning heating module fails.

[0076] The refrigeration equipment is mainly an air conditioning refrigeration module. When the temperature data is higher than the preset temperature upper limit, the controller 14 controls the air conditioning refrigeration module to turn on to reduce the temperature inside the box.

[0077] The dehumidification device includes an air conditioning dehumidification module and a dehumidifier. When the temperature data of the air conditioning dehumidification module is higher than the preset temperature lower limit and lower than the preset temperature upper limit, and the humidity data is about the preset humidity upper limit, the controller 14 controls the air conditioning dehumidification module to turn on to reduce the humidity inside the box. The dehumidifier is an auxiliary dehumidification device. The dehumidifier can be used when the air conditioning dehumidification module is not sufficient to provide sufficient dehumidification effect, or as a backup when the air conditioning dehumidification module fails.

[0078] By integrating a variety of temperature and humidity adjustment devices, the system in this embodiment can more accurately adjust the temperature and humidity inside the cabinet to ensure that the temperature and humidity in each area are maintained at an optimal state.

[0079] Furthermore, in a specific embodiment, the above-mentioned substation switch cabinet box environment monitoring and control system further includes: a circulating fan 17;

[0080] The circulation fan 17 is linked with the dehumidifier. When the dehumidifier is turned on, the head of the circulation fan 17 is turned on.

[0081] In this embodiment, the system is newly provided with a circulating fan 17, which is linked with the dehumidifier. When the dehumidifier is turned on, the air outlet of the circulating fan 17 is opened to assist air circulation and enhance the dehumidification effect.

[0082] The dehumidifier is responsible for reducing the humidity inside the cabinet and removing moisture from the air through the principle of condensation. The dehumidifier's on state triggers the start of the circulation fan 17 to ensure air circulation and improve dehumidification efficiency. The circulation fan 17 is responsible for circulating air inside the cabinet to help evenly distribute temperature and humidity, while assisting the dehumidification equipment to improve dehumidification efficiency. The fan's air outlet is designed to be openable and closable. When the dehumidifier is started, the fan head automatically opens to maximize air circulation.

[0083] With the help of the circulating fan 17, the dry air generated by the dehumidifier can be distributed to all corners of the box more quickly, thereby improving the overall dehumidification efficiency. The air circulation of the circulating fan 17 helps prevent localized wet areas from appearing inside the box and maintains the uniformity of the overall environment. Maintaining an appropriate humidity level helps extend the service life of the equipment in the switch cabinet and reduce equipment damage caused by excessive humidity.

[0084] Further, in a specific embodiment, in the above-mentioned substation switch cabinet box environment monitoring and control system, the controller 14 includes an image processing unit;

[0085] After receiving the infrared signal sent by the infrared sensor 13, the controller 14 analyzes it through the image processing unit to distinguish between human targets and non-human targets, and controls the sound device 16 to emit an expelling sound to expel the animal according to the analysis result.

[0086] In this embodiment, the controller 14 includes an image processing unit, which can receive the infrared signal from the infrared sensor 13 and analyze it to distinguish whether there is a human target or a non-human target. According to the analysis result, the controller 14 can control the sound device 16 to emit an expulsion sound to expel the animal.

[0087] The controller 14 is not only responsible for receiving data from the temperature and humidity sensor 11 and the infrared sensor 13, but also needs to further analyze the infrared data through the image processing unit. When the controller 14 receives the infrared signal sent by the infrared sensor 13, the image processing unit immediately analyzes it and decides whether to activate the sound device 16 based on the analysis result. The image processing unit receives and analyzes the infrared image data captured by the infrared sensor 13, performs real-time analysis on the infrared image, identifies the target object in the image, and determines whether it is a human or non-human target.

[0088] When a non-human target (such as a small animal) is detected, the sound device 16 is responsible for emitting a sound of a specific frequency to drive the animal away. The activation of the sound device 16 is controlled by the controller 14 according to the analysis result of the image processing unit.

[0089] By distinguishing between human and non-human targets, the system can avoid false alarms and activate the sound device only when a non-human target is detected, thereby improving the safety and efficiency of the system. Intelligent identification of small animals and automatic expulsion sounds reduce the need for human intervention and also reduce the damage that small animals may cause to the equipment.

[0090] Furthermore, in a specific embodiment, the above-mentioned substation switch cabinet box environment monitoring and control system further includes: a remote terminal 18;

[0091] The controller 14 is connected to the remote terminal 18 , and sends the cabinet status information to the remote terminal 18 , receives the control instructions sent by the remote terminal 18 , and controls the temperature and humidity adjustment device 15 and the sound device 16 according to the control instructions.

[0092] In this embodiment, a remote terminal 18 is newly added to the system, and the terminal is connected to the controller 14. The controller 14 is responsible for sending the cabinet status information to the remote terminal 18 in real time, receiving control instructions from the remote terminal 18, and controlling the temperature and humidity adjustment device 15 and the sound device 16 according to these instructions.

[0093] The controller 14 is not only responsible for monitoring and controlling the temperature and humidity inside the box, but also needs to send status information to the remote terminal 18 and receive control instructions from the remote terminal 18. The remote terminal 18 is used to receive the box status information sent by the controller 14 and allow the operator to send control instructions. The controller 14 exchanges data with the remote terminal 18 through the built-in communication module. The communication module supports standard communication protocols to ensure the security and accuracy of data transmission. The temperature and humidity adjustment device 15 and the sound device 16 perform corresponding operations according to the instructions of the controller 14, such as opening or closing, to adjust the temperature and humidity inside the box or expel small animals.

[0094] The operator can view the box status in real time through the remote terminal 18, including temperature and humidity data and the box door status, so as to timely understand the internal environment of the box. The operator can send control instructions to the controller 14 based on the information received by the remote terminal 18 to remotely adjust the temperature and humidity inside the box or control the sound device 16. The remote monitoring and control function reduces the dependence on on-site personnel, reduces maintenance costs, and improves the operating efficiency of the system.

[0095] Furthermore, in a specific embodiment, the above-mentioned substation switch cabinet box environment monitoring and control system further includes: a pan-tilt camera;

[0096] The pan-tilt camera is connected to the controller 14 . When the controller 14 recognizes a non-human target, it controls the pan-tilt camera to take a target image and sends the target image to the remote terminal 18 .

[0097] In this embodiment, a pan-tilt camera is added to the system, and the camera is connected to the controller 14. When the controller 14 recognizes a non-human target through the image processing unit, it controls the pan-tilt camera to automatically adjust the position and focus, take a picture of the target, and send the picture to the remote terminal 18.

[0098] The image processing unit inside the controller 14 is responsible for analyzing the data of the infrared sensor 13. When a non-human target is detected, the controller 14 sends a command to the pan-tilt camera to take a picture of the target. The pan-tilt camera is responsible for capturing real-time images inside the box and can adjust the shooting angle and focal length according to the command of the controller 14. The pan-tilt camera is connected to the controller 14 through wired or wireless communication to ensure the timely communication of control commands and real-time transmission of image data.

[0099] The remote terminal 18 is used to receive the target images sent by the controller 14 and allow the operator to view and analyze these images. The system can quickly respond and record the presence of non-human targets, and promptly notify the operator through the remote terminal 18, thereby improving the system's response speed and processing efficiency. By taking target images and sending them to the remote terminal 18, the system provides additional security for the operator, enabling them to better assess and respond to potential security threats.

[0100] Further, in a specific embodiment, in the above-mentioned substation switch cabinet box environment monitoring and control system, the sound device 16 includes a speaker and an audio signal generator;

[0101] The audio signal generator is used to generate a sound signal of a specific frequency, and the speaker is used to play the sound signal;

[0102] The controller 14 controls the frequency, volume and playing duration of the sound signal generated by the audio signal generator.

[0103] In this embodiment, the sound device 16 includes a speaker and an audio signal generator, which work together to generate a sound signal of a specific frequency to drive away small animals in the box. The controller 14 determines whether to activate the sound device 16 based on the infrared data detected by the infrared sensor 13, and controls the audio signal generator to generate a sound signal with an appropriate frequency, volume and playing time.

[0104] The controller 14 is responsible for receiving data from the infrared sensor 13 and deciding whether to activate the sound device 16 accordingly. Based on the data analysis results of the infrared sensor 13, the controller 14 controls the audio signal generator to generate a sound signal of a specific frequency and adjusts the volume and playing time of the speaker to achieve the most effective expulsion effect. By automatically expelling small animals, the need for manual patrols and manual processing is reduced, thereby reducing maintenance costs.

[0105] Furthermore, in a specific embodiment, the above-mentioned substation switch cabinet box environment monitoring and control system further includes: a human-machine interaction interface; the human-machine interaction interface is connected to the controller 14;

[0106] The human-machine interaction interface receives and displays the cabinet status information and receives the control instructions input by the operator.

[0107] In this embodiment, a human-computer interaction interface is newly added to the system, which is connected to the controller 14. The human-computer interaction interface is responsible for receiving the cabinet status information sent by the controller 14 and presenting it to the operator in the form of graphics or text. At the same time, the operator can input control instructions through the human-computer interaction interface, such as adjusting the temperature and humidity setting values, starting or stopping specific equipment, etc.

[0108] The controller 14 is not only responsible for monitoring and controlling the temperature and humidity inside the box, but also needs to send status information to the human-machine interface and receive control instructions input by the operator through the interface. The controller 14 exchanges data with the human-machine interface through a built-in communication module.

[0109] The operator can intuitively view the cabinet status, including temperature and humidity data, cabinet door status, and small animal activities, through the human-computer interaction interface. The operator can input control instructions in real time, such as adjusting the temperature and humidity setpoints or starting specific equipment, so as to manage the cabinet environment more effectively. When an abnormal state is detected, the system can quickly notify the operator through the human-computer interaction interface, which improves the system's response speed. The operator can perform fault diagnosis and maintenance operations through the human-computer interaction interface, which simplifies the maintenance process and improves maintenance efficiency.
