Description

TECHNICAL FIELD

[0001] The present invention relates to a switchboard control system for fire and earthquake sensing using a plurality of sensors.

[0002] In particular, the present invention uses the respective detection values of temperature sensors, humidity sensors and vibration sensors installed in the upper and lower portions of the switchboard as data for understanding the state of the switchboard, and in the case of a sharp change in the difference between the detection values of the upper and lower portion sensors, the state of the switchboard can be determined by fire, earthquake, etc., and measures such as alarm can be taken. BACKGROUND

[0003] Generally, in the case of private electric devices such as buildings or factories, since the required power is large, it is not possible to obtain power directly usable from the power company as in the case of ordinary electric devices using 110V or 220V low voltage.

[0004] Therefore, in the case of general private electric devices, high voltage of 3300V or 6600V must be received from the distribution line of the substation, and then converted into a commonly used voltage, and in the case of private electric devices in large-scale buildings, particularly high voltage of 22.9kV must be received and then converted into a commonly used voltage, and the device for achieving this is the entire power distribution network.

[0005] These hydroponic units include a distribution panel, an MCC panel (Motor Control Center Panel), a low voltage panel, a high voltage panel, a transformer base, and an extra-high voltage panel, etc.

[0006] These distribution panels are composed of high voltage supplied from a substation, a hydroelectric device for obtaining extra-high voltage, a transformer device for reducing the high voltage supplied from the substation to a commonly used voltage, a distribution device for supplying the reduced voltage to electric appliances or lighting in each part of the building, and safely and efficiently supply power to the building.

[0007] The conventional hydroponic unit is composed of electric appliances required before hydroponics and a hydroponic unit case for accommodating the electric appliances required before hydroponics. According to this conventional technology, the hydroponic unit is installed in a manner that the hydroponic unit case is fixed to the ground by an anchor bolt, and the conventional hydroponic unit does not have a separate anti-seismic device, and thus has a problem of being easily affected by an earthquake.

[0008] Specific anti-seismic distribution panels according to conventional technology are as follows:

[0009] Korean Patent Publication No. 10-2024-0020058 includes a front-mounted outer casing with a door, a power distribution unit inside the casing, and power lines and branch lines connected to the power distribution unit. The casing consists of two parts, left and right. Rotating the two sides of the front of the casing opens the power distribution panel on the front. A ventilation hole is formed on one side of the door. The ventilation hole has the characteristic of measuring the internal temperature of the casing, raising the internal temperature of the casing, thereby raising the temperature of the fan inside the casing. Regarding a power distribution panel equipped with a ventilation fan, when the internal temperature of the casing rises, the ventilation fan automatically starts to ventilate the air inside the casing. By maintaining a constant internal temperature, it can prevent the internal temperature of the casing from becoming too high, which could cause malfunctions in the power distribution unit. It also has a power-off mechanism that automatically cuts off the power supply through the power line in the event of an earthquake or fire, thus preventing fires caused by leakage during earthquakes and preventing the spread of fires inside the casing.

[0010] Korean Patent Registration No. 10-1737822 describes a base plate with a four-cornered plate shape; a distribution panel body with a hexahedral shape, the bottom surface of which is separated from the top of the base plate; the top of the base plate includes a feed screw extending parallel to one side of any one of the four sides in the other directions, a feed screw fixing bracket that fixes the feed screw to the base plate so that it can rotate, and four height adjustment devices that are combined with the feed screw to allow it to pass through and move horizontally with the rotation of the feed screw; a second rotating bracket, including a first rotating bracket fixed to the top of the feed block and a height adjustment device for mounting the first rotating bracket, is fixed to the bottom of the distribution panel body located in the extended direction; and a damper with elastic restoring force that is rotatably connected to the first and second rotating brackets on both sides and extends upwardly. The device has shock absorption performance and overall shock absorption performance. The four dampers support the bottom of the distribution panel body at an angle rather than vertically, enabling the dampers to react to and absorb longitudinal vibrations and to react to lateral vibrations or impacts. This protects the distribution panel and internal equipment from earthquakes and vibrations and impacts that may occur under various conditions. The relatively fast reaction of the vibration-generated compression coil springs can withstand the pressure of the moving valve plate through the lifting structure, thereby achieving the expected vibration reduction and damping effect, and thus achieving the overall vibration reduction effect.

[0029] an alarm unit for processing the detection values transmitted from the upper sensor module and the lower sensor module, respectively, and audibly displaying disaster information based on the processing result so that the administrator can recognize the occurrence of fire or earthquake; and

[0030] In the present invention, the control device performs the following steps:

[0031] a normal judgment stage in which the temperature deviation between the upper and lower portions of the switchboard is small, the temperature change rate between the upper and lower portions is similar, the humidity deviation between the upper and lower portions of the switchboard is small, the humidity change rate between the upper and lower portions is similar, and it is judged to be normal when the temperature and humidity set values are within the set values;

[0033] based on the disaster judgment stage, a disaster recognition stage is performed by the LCD and the alarm unit to inform the administrator that a disaster has occurred.

[0034] In the present invention, the control device performs the following steps:

[0035] a normal judgment stage in which the vibration deviation between the upper and lower portions of the switchboard is small, the vibration change rate between the upper and lower portions is similar, and it is judged to be normal when the vibration set value is within the set value;

[0036] a disaster judgment stage in which the vibration deviation between the upper and lower portions of the switchboard is large, the vibration change rate between the upper and lower portions is large, and it is judged that an earthquake has occurred when the vibration set value is greater than the set value; and

[0037] based on the disaster judgment stage, a disaster recognition stage is performed by the LCD and the alarm unit to inform the administrator that a disaster has occurred.

[0038] In the present invention, the fire disaster alarm condition (C) derived from processing the detection values of the upper temperature sensor and the lower temperature sensor is:

[0039] C = ((v2 - v1) / T) > set value.

[0040] where v2 is the temperature change rate of the upper temperature sensor in the range in which it can be judged to be a fire, v1 is the temperature change rate of the lower temperature sensor in the range in which it can be judged to be a fire, and T is the range in which it can be judged to be a fire.

[0044] In the present application, the earthquake disaster warning condition (C) derived from processing the detection values of the upper and lower vibration sensors is:

[0045] C = (v2 / v1) > set value.

[0046] wherein v2 is the vibration change rate of the upper vibration sensor in the interval that can be judged as an earthquake, v1 is the vibration change rate of the lower vibration sensor in the interval that can be judged as an earthquake, and T is the interval that can be judged as an earthquake.

[0048] According to the power distribution panel control system for fire and earthquake detection using the multi-sensor of the present application, the detection values of the temperature sensor, humidity sensor and vibration sensor respectively installed in the upper and lower portions of the power distribution panel are used as data for understanding the state of the power distribution panel, and in the case of a sharp change in the difference between the detection values of the upper and lower sensors, the power distribution panel condition can be judged by fire and earthquake, etc. and measures such as alarm can be taken.

[0049] In addition, if a fire occurs, hot gas and flames rise upward due to convection, and a different temperature deviation and temperature change rate between the upper and lower portions of the power distribution panel occurs, so the occurrence of a fire can be quickly and accurately sensed.

[0050] Furthermore, if a fire occurs, the humidity changes with the temperature rise in the early stage of the fire, and based on the difference in humidity deviation and humidity change rate between the upper and lower portions of the power distribution panel, the occurrence of a fire can be quickly and accurately detected.

[0051] In addition, if the power distribution panel has an earthquake condition that can be judged as an earthquake, based on the difference in vibration deviation and vibration change rate between the upper and lower portions of the power distribution panel, the occurrence of an earthquake can be quickly and accurately detected.

[0074] [First Embodiment]

[0075] Figure 1 is a drawing of a switchboard in which sensor modules are installed in the upper and lower parts, according to the first embodiment of the present application, Figure 2 is a drawing of a control system composed of sensor modules and a control device, according to the first embodiment of the present application. Figure 3 is a schematic diagram of detecting a fire using temperature sensors included in the upper and lower sensor modules, according to the first embodiment of the present application.

Figure 6 is a schematic diagram of detecting a fire using vibration sensors included in the upper and lower sensor modules, according to the first embodiment of the present application. Figure 7 is an action flowchart of sensing an earthquake and notifying an administrator based on the upper and lower vibration.

[0076] Figure 8 is a schematic diagram of a switchboard control system using a digital communication method energy sensing passive sensor, according to an embodiment of the present application.

[0077] As Figure 1 shown, a switchboard implementing the first embodiment of the present application has a plurality of sensor modules 100, 200 installed in the upper and lower parts inside thereof.

[0078] Figure 1 As shown, the upper sensor module 100 is installed at the upper portion inside the switchboard, and the lower sensor module 200 is installed at the lower portion inside the switchboard, but is not necessarily limited to being installed at these locations.

[0079] As shown in FIG. 1, the switchboard control system according to the present application is composed of a temperature sensor 110 for detecting the temperature at the upper portion inside the switchboard, a humidity sensor 120 for detecting the humidity at the upper portion inside the switchboard, a vibration sensor 130 for detecting the vibration at the upper portion inside the switchboard, an upper sensor module 100 composed of the temperature sensor 110, the humidity sensor 120, and the vibration sensor 130, a temperature sensor 210 for detecting the temperature at the lower portion inside the switchboard, a humidity sensor 220 for detecting the humidity at the lower portion inside the switchboard, a vibration sensor 230 for detecting the vibration at the lower portion inside the switchboard, a lower sensor module 200 composed of the temperature sensor 210, the humidity sensor 220, and the vibration sensor 230, a control device 300 composed of an alarm unit 320 for driving a warning light or a buzzer in various forms so that the manager can confirm the occurrence of an abnormal situation such as a fire or an earthquake, and an LCD 310 for processing the detection values transmitted from the upper sensor module 100 and the lower sensor module 200 and displaying the processed results in various forms so that the manager can confirm the occurrence of an abnormal situation such as a fire or an earthquake. Figure 2 The present application uses the detection values of the temperature sensor, the humidity sensor, and the vibration sensor, which are installed at the upper and lower portions inside the switchboard, as data for monitoring the real-time state of the switchboard, and compares the detection values detected by the upper and lower sensors, and when a sharp increase in the difference is found, it is determined that an abnormal situation such as a fire or an earthquake has occurred, and an alarm is given.

[0080] The operation of detecting a fire using the temperature sensor will be described.

[0081] If an abnormal situation such as a fire occurs inside the switchboard, when a fire occurs, hot gas and flames have a tendency to rise upward due to convection.

[0082] Therefore, the upper temperature sensor 110 detects a sharp increase in the temperature inside the switchboard earlier than the lower temperature sensor 210.

[0083] That is, when a fire occurs, the lower temperature sensor 210 also detects a change in the temperature different from that during normal times, but since hot gas and flames rise upward due to convection, the upper temperature sensor 110 detects a state that can be determined as a fire earlier than the lower temperature sensor 210, and thus the lower temperature sensor 210 detects a state that can be determined as a fire later than the upper temperature sensor 110. That is, the speed of detecting a state of a sharp change in the temperature inside the switchboard is faster in the upper portion than in the lower portion.

[0084]

[0085] ​Furthermore, during a fire, not only the upper temperature sensor 110 but also the lower temperature sensor 210 will show significant changes in their readings, although the upper temperature sensor 110 will detect a higher temperature than the lower temperature sensor 210. These differences also help identify the presence of a heat source.

[0086] Therefore, this invention utilizes these principles to detect fires.

[0087] like Figure 3 As shown, under normal conditions, the temperature difference between the upper and lower parts of the distribution panel is small, and the temperature change rate between the upper and lower parts is similar.

[0088] However, in the zone T where the fire occurred, there was a significant difference in the rate of temperature change between the upper and lower temperature sensors.

[0089] Therefore, if the temperature change rate exceeds the set value, the control device 300 confirms to the administrator that a disaster has occurred via the LCD 310 and the alarm unit 320.

[0090] At this point, the fire disaster alarm condition (C) can be defined as the following mathematical formula 1:

[0091] [Mathematical Expression 1]

[0092] C = ((v2-v1) / T) > Setting value

[0093] Where v2 is the temperature change rate of the upper temperature sensor in the zone that can be identified as a fire, v1 is the temperature change rate of the lower temperature sensor in the zone that can be identified as a fire, and T is the zone that can be identified as a fire.

[0094] Next, we will explain how to use humidity to detect fires.

[0095] The method of using the difference in detection values ​​between the upper and lower temperature sensors for fire detection can also be similarly applied to humidity detection.

[0096] If a fire occurs inside the distribution panel, the humidity will change as the temperature rises in the early stages of the fire. When the temperature rises, the warm air retains more moisture, thus reducing the relative humidity. Therefore, the relative humidity initially detected by the upper humidity sensor 120 will decrease.

[0097] At this time, the lower humidity sensor 220 will also detect the decrease in relative humidity. However, as mentioned above, the heating rate of the lower part is slower than that of the upper part. Therefore, the lower humidity sensor 220 will detect the rapid change in humidity more slowly than the upper humidity sensor 120.

[0098] Therefore, this invention utilizes these principles to detect fires.

[0099] likeFigure 4 As shown, the humidity deviation in the switchboard is small under normal conditions, and the humidity change rate between the upper and lower humidity sensors is similar.

[0100] However, in the section T where a fire occurs, there is a large difference in the humidity change rate between the upper and lower humidity sensors.

[0101] Therefore, if the change rate exceeds the set value, the control device 300 confirms to the administrator that a disaster has occurred through the LCD 310 and the alarm unit 320.

[0102] At this time, the fire disaster alarm condition (C) can be defined as the following mathematical formula 2:

[0103] [mathematical formula 2]

[0104] C = (v2-v1) / T) > can be defined as a set value.

[0105] where v2 is the humidity change rate of the upper humidity sensor in the section that can be judged as a fire, v1 is the humidity change rate of the lower humidity sensor in the section that can be judged as a fire, and T is the section that can be judged as a fire.

[0106] On the other hand, as described above, the principle of sensing a fire by using temperature and humidity respectively is used, but as shown in FIG. 6, only when both the temperature and humidity satisfy the conditions that can be judged as a fire, a disaster alarm can be performed. Figure 5

[0107] In this case, the control unit 300 judges that it is normal in the normal judgment stage S10 when the temperature deviation between the upper and lower parts of the switchboard is small, the temperature change rate between the upper and lower parts is similar, and the humidity deviation between the upper and lower parts of the switchboard is small, the humidity change rate between the upper and lower parts is similar, and the temperature and humidity set values are within the set values; judges that a disaster has occurred in the disaster judgment stage S20 when the temperature deviation between the upper and lower parts of the switchboard is large, the temperature change rate between the upper and lower parts is large, and the humidity deviation between the upper and lower parts is large, the humidity change rate between the upper and lower parts is large, and the temperature and humidity set values are greater than the set values; and performs a control action composed of the disaster awareness stage S30 based on the disaster judgment stage, making the administrator aware of the occurrence of a disaster through the LCD and the alarm unit; and the disaster alarm stage S40.

[0108] Next, the action of sensing an earthquake by using vibration will be described.

[0109] If the switchboard is in a situation that can be judged as an earthquake, the upper vibration sensor 130 of the switchboard usually exhibits a larger vibration amplitude than the lower vibration sensor 230. This is because the principle of the lever makes the top of a high object move more than the ground when the ground moves.

[0110] Therefore, the top of the switchboard is farther from the center of mass, and thus amplifies the detected motion.​

[0111] The lower vibration sensor 230 is closer to the ground than the upper vibration sensor 130, so it can record a smaller amplitude and a lower magnification of the swaying motion.

[0112] Therefore, this invention utilizes these principles to sense earthquakes.

[0113] like Figure 6 As shown, the vibration deviation is small under normal conditions, and the vibration values ​​between the upper vibration sensor 130 and the lower vibration sensor 230 differ significantly.

[0114] Therefore, if the rate of change exceeds the set value, the control device 300 confirms to the administrator that a disaster has occurred via the LCD 310 and the alarm unit 320.

[0115] In other words, such as Figure 7 As shown, the control device 300 senses the occurrence of an earthquake based on the vibration of the upper and lower parts. When the vibration deviation between the upper and lower parts of the distribution panel is small and the vibration change rate between the upper and lower parts is similar and within the vibration set value, it is judged as a normal judgment stage S10. When the vibration deviation between the upper and lower parts of the distribution panel is large and the vibration change rate between the upper and lower parts is large, if it exceeds the vibration set value, it is judged as a disaster judgment stage S20, indicating that an earthquake has occurred. Based on the disaster judgment stage, there is a disaster awareness stage 9S30, in which the administrator is made aware of the disaster through the LCD and alarm unit, and the control actions are executed.

[0116] At this point, the earthquake disaster warning condition (C) can be defined as the following mathematical formula 3:

[0117] [Mathematical Expression 3]

[0118] C = (v2 / v1) > setting value

[0119] Where v2 is the vibration change rate of the upper vibration sensor within the interval that can be identified as an earthquake, v1 is the vibration change rate of the lower vibration sensor within the interval that can be identified as an earthquake, and T is the interval that can be identified as an earthquake.

[0120] in addition, Figure 2 The control system shown can be like Figure 8 The same variation is implemented.

[0121] like Figure 8 As shown, a distribution panel control system that can use multiple sensors for fire and earthquake detection may include sensor modules 100 and 200, antennas, control devices 300, network N, control server 400, and smart devices 500, which are respectively installed in the upper and lower parts of the distribution panel.

[0122] The sensor module 100200 is composed of a communication part, respectively.

[0123] These switchboard control systems can predict and prevent the danger of the switchboard by placing the antenna and control device 300 in an isolated location on the switchboard and using the sensor module 100200 to monitor the main circuit used by the switchboard and the state inside the switchboard, and the sensor module 100 is equivalent to a passive sensor inside the switchboard driven by energy induction.

[0124] In Figure 8 , the network N is a high-speed backbone network of a large communication network that can provide large-capacity, long-distance voice and data services - a communication network that can be a new generation of wired and wireless networks that provide the Internet or high-speed multimedia services.

[0125] The network N, if it is a mobile communication network, can be a synchronous mobile communication network or an asynchronous mobile communication network.

[0126] As an example of an asynchronous mobile communication network, a communication network in the WCDMA (Wideband Code Division Multiple Access) mode can be cited. In this case, although not shown in the figure, the mobile communication network can include an RNC (Radio Network Controller).

[0127] On the other hand, although the WCDMA network is taken as an example, it can be a next-generation communication network such as 5G or other IP-based IP network in addition to 3G LTE networks, 4G networks, and others.

[0128] The network N is responsible for transmitting signals and data between the control device 300, the control server 400, the smart device 500, and other systems.

[0129] According to the switchboard control system of the present application, the sensor module 100200 equipped with multiple sensors detects the state in which an accident can occur in the dead angle of the inside of the switchboard through the sensors, and processes the detected monitoring information on the control device 300 to determine whether an abnormality has occurred in the switchboard.

[0130] Similarly, the state inside the switchboard determined by the control device 300 is transmitted to the remote control center 400 and the smart device 500 held by the administrator through the network N so that measures can be taken if necessary.

[0131] [Second Embodiment]

[0132] Figure 9 and Figure 10is a diagram for helping understanding of a technique according to a second embodiment of the present application, which divides an inside of a switchboard into a plurality of regions and judges temperatures of the regions.

[0133] The second embodiment is a technique for judging whether each device or electrically connected part, etc. constituting an inside of a switchboard is normal or abnormal, and realizing temperature judgment of a plurality of divided regions.

[0134] For this, as shown in Figure 1 , it is possible to judge whether each device or electrically connected part, etc. in a switchboard is normal or abnormal based on temperatures detected in upper and lower parts of the switchboard, but in the second embodiment, as shown in Figure 9 , the temperature detection regions in the switchboard can be divided into five regions. That is, in the first embodiment, a technique of installing temperature sensors in upper and lower parts and judging a fire based on sensed values thereof was introduced, but the second embodiment judges temperatures of a plurality of regions in an inside of a switchboard before judging a fire, so that appropriate measures such as heat release can be taken.

[0135] Here, as shown in Figure 9 , it is possible to predict that the inside of a water culture whole is divided into five temperature regions, and judge whether temperatures of each region exceed a standard (normal) temperature.

[0136] Here, the sensed temperature means a temperature sensed by each region, and the judged temperature means a temperature of each region, more accurately, a temperature reflecting a degree of influence of hot air on other regions, so that it is judged as a final temperature of the region. Figure 10 The concept of judging a final temperature based on a degree of influence of each region on other regions is listed in

[0137] For example, an inside of a switchboard is composed of various devices and wiring, electrically connected parts, etc., so it is possible to divide positions where they are placed by a plurality of methods such as upper and lower or left and right, and detect temperatures generated in each divided region. The temperature sensors can detect temperatures by temperature sensors, and the detected temperatures are processed by the control device 300, so that temperatures of the regions are judged.

[0138] If a more detailed explanation is given to Figure 10 , as described in the first embodiment, considering that hot air generated in an inside of a switchboard generally moves upward, for example, it is possible that a temperature detected in a given region is higher than a reference temperature due to the hot air moving upward, so considering this, a final temperature of each region is judged.

[0139] That is, since hot air has a characteristic of moving upward, for example, as shown in Figure 2If the optimal side inside the switchboard is set as the first temperature zone, and the second, third, fourth, and fifth temperature zones are set in order from below, it can be presumed that in many cases, the heat generated in the third, fourth, and fifth temperature zones will particularly affect the first and second temperature zones.

[0140] Therefore, for example, even if the temperature detected in the first and second temperature zones is higher than the reference temperature, a certain degree of allowable value can be set in advance, and as long as it does not exceed the allowable value, it can be determined that the temperature of the zone is normal.

[0141] In addition, if any of the divided temperature zones exceeds the standard temperature range, the switchboard can also be controlled to stop driving or heat dissipation.

[0142] The scope of the present application is not limited to the described embodiments, and can be embodied in various forms within the scope of the attached patent claims. Furthermore, those skilled in the art to which the present application pertains can transform it into various ranges without departing from the gist of the present application requested in the patent claims, and all of them are within the scope of the present application requested in the patent claims.
