Abstract
Description
Technical Field
[0001] This invention belongs to the field of vehicle safety monitoring and cooling technology, and specifically relates to an intelligent water spray cooling control system for monitoring vehicle wheel hub temperature. Background Technology
[0002] During vehicle operation, especially for heavy-duty vehicles facing long downhill slopes, the braking system needs to operate frequently, generating a large amount of heat that is transferred to the wheel hubs, causing a rapid increase in wheel hub temperature. This is a common and serious problem in the operation of wheeled vehicles that urgently needs to be addressed. High temperatures in the brakes and wheel hubs directly lead to decreased braking performance and reduced braking sensitivity. In severe cases, it can cause safety accidents such as brake failure, vehicle fires, and tire blowouts, posing a significant threat to the personal safety and property of drivers.
[0003] To address these issues, automatic high-temperature brake water spray systems have emerged. However, existing systems suffer from several drawbacks: most lack precise temperature monitoring capabilities, failing to track wheel hub temperature changes in real time and relying solely on driver experience to manually control the spray system, which can lead to delayed or excessive spraying; some devices with temperature measurement functions use sensors with poor stability and large measurement errors, lacking self-testing capabilities and prone to monitoring failure; furthermore, existing systems lack tiered warning mechanisms, failing to promptly alert drivers to potential risks based on temperature changes and hindering precise linkage between the water spray system and temperature monitoring, making it difficult to fundamentally prevent various safety accidents caused by high temperatures; additionally, the sensors and cables in existing systems have poor weather resistance, are easily damaged in harsh environments, and have short service lives, failing to meet the needs of heavy-duty vehicles operating outdoors for extended periods. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as inaccurate vehicle wheel hub temperature monitoring, untimely early warning, unintelligent water spray control, and poor device durability. It provides an intelligent water spray cooling control system for vehicle wheel hub temperature monitoring. Through precise temperature measurement, tiered early warning, and intelligent water spray linkage, it achieves real-time monitoring and automatic cooling of wheel hub temperature, preventing safety accidents such as brake failure, tire blowout, and spontaneous combustion caused by high temperatures, ensuring driver safety, and improving the durability and stability of the device to adapt to various harsh operating environments.
[0005] The technical solution of this invention is implemented as follows: A vehicle wheel hub temperature monitoring and intelligent water spray cooling control system includes a temperature acquisition module, a control module, a display module, an early warning module, and a water spray linkage module. The modules are electrically connected and work together to form a closed-loop control of monitoring-early warning-cooling. The temperature acquisition module is used to collect temperature data of each wheel hub of the vehicle in real time and transmit it to the control module. The control module is used to receive temperature data and compare it with a preset threshold, and send control commands to other modules; The display module is used to display the hub temperature and system operating status in real time. The early warning module is used to receive control commands and issue audible and visual warnings. The water spray linkage module is used to connect to the vehicle's water spray system, receive control commands to start and stop the water spray, and reduce the wheel hub temperature.
[0006] Preferably, the temperature acquisition module uses a digital temperature sensor, with one digital temperature sensor configured for each wheel hub. The digital temperature sensor has a self-test function, which can automatically detect its own working status, and the measurement error is controlled within ±1℃.
[0007] Preferably, the control module has three preset thresholds: a warning threshold, an upper limit threshold for starting the water spray, and a lower limit threshold for stopping the water spray. The warning threshold is set to 85℃, the upper limit threshold for water spray activation can be preset to 60℃ and can be adjusted according to the vehicle's operating conditions, and the lower limit threshold for water spray shutdown can be preset to 40℃ and can be adjusted according to the vehicle's operating conditions.
[0008] Preferably, the display module uses an LCD screen, which can display the current temperature of each wheel hub in real time. When the temperature of a wheel hub exceeds the warning threshold, the display icon corresponding to that wheel hub will automatically turn red, and the warning status and the working status of the water spray system will be displayed simultaneously.
[0009] Preferably, the early warning module adopts an audible and visual alarm device, which issues an audible and visual alarm every 3 minutes when the wheel hub temperature reaches the early warning threshold, until the wheel hub temperature is lower than the early warning threshold. If the wheel hub temperature continues to rise, an audible and visual alarm will be triggered for every 1°C increase. No new alarm will be triggered when the temperature drops. If the temperature remains above the warning threshold, an alarm will be triggered every 3 minutes.
[0010] Preferably, the water spray linkage module is connected to the vehicle's existing water spray system. When the wheel hub temperature reaches the upper limit threshold for water spray activation, it receives the activation command from the control module and triggers the water spray system to start. When the wheel hub temperature drops to the lower threshold of the water spray shutdown, the control module receives a shutdown command, triggering the water spray system to shut down.
[0011] Preferably, the digital temperature sensor and connecting cable are made of high-temperature and corrosion-resistant materials, which can adapt to harsh environments such as high and low temperatures, dust, and humidity during vehicle operation, and ensure long-term stable operation.
[0012] Preferably, the system workflow includes the following steps: Step 1: After the vehicle is started, the temperature acquisition module starts and collects temperature data of each wheel hub, and performs sensor self-test simultaneously. Step 2: The control module analyzes and processes the temperature data and compares it with a preset threshold. Step 3: The display module shows the temperature and system status; Step 4: Based on the comparison results between temperature and threshold, trigger the alarm of the early warning module or start / stop the water spray linkage module. Step 5: Once the wheel hub temperature is below the warning threshold, the system resumes normal monitoring and repeats the above steps.
[0013] Preferably, the control module is a microcontroller, installed in the vehicle cab, and electrically connected to the temperature acquisition module, display module, early warning module, and water spray linkage module via wiring. The alarm sound of the warning module is no less than 80dB, and the light flashes red.
[0014] Preferably, the system is applicable to all types of wheeled vehicles, especially heavy-duty vehicles. The preset threshold can be manually adjusted according to the actual vehicle working conditions. It is easy to install and does not require large-scale modification of the vehicle.
[0015] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. Accurate temperature measurement and high stability: It adopts a digital temperature sensor with self-testing function, and the measurement error is controlled within ±1℃. It can collect wheel hub temperature data in real time and accurately, avoiding untimely or false alarms caused by inaccurate temperature measurement. At the same time, the sensor and cable are made of high temperature and corrosion resistant materials, which can adapt to harsh environments, improve system stability and service life, and solve the problems of large temperature measurement error and poor durability of existing devices. II. Timely and accurate early warning: An 85℃ early warning threshold is set, combined with a graded alarm mechanism. When the temperature reaches the threshold, an alarm is triggered every 3 minutes. If the temperature continues to rise, an alarm is triggered every 1℃. This can promptly remind the driver of the risk of high temperature in the wheel hub. At the same time, the abnormal wheel hub is displayed intuitively through the display module, which makes it easy for the driver to quickly locate the problem. This solves the shortcomings of the existing device in that the early warning is not timely and there is no graded early warning. 3. Intelligent, precise and efficient water spraying: The water spraying system is automatically linked with temperature monitoring. By preset upper and lower thresholds for water spraying, the system can be automatically controlled to start and stop, ensuring timely cooling while avoiding excessive water spraying and wasting water resources. This solves the problems of unintelligent water spraying control and poor cooling effect in existing devices. IV. Comprehensive Safety Assurance: Through closed-loop control of real-time temperature monitoring, graded early warning, and automatic water cooling, it effectively prevents safety accidents such as brake failure, tire blowout, and spontaneous combustion caused by high wheel hub temperature, significantly improves vehicle driving safety, protects the personal and property safety of drivers, and solves the problem that existing technologies cannot fundamentally avoid the safety risks of high temperature. V. High versatility and practicality: Applicable to all types of wheeled vehicles, especially heavy-duty vehicles. The preset threshold can be adjusted according to actual working conditions. It is easy to install, does not require large-scale vehicle modification, and is easy to promote and apply.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the accompanying drawings and specific circumstances.
[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0022] like Figure 1-3 As shown, the present invention provides an intelligent water spray cooling control system for monitoring vehicle wheel hub temperature, comprising the following modules: I. Temperature Acquisition Module The temperature acquisition module employs advanced digital temperature sensors, with one sensor configured for each wheel hub. These sensors are directly installed at designated monitoring locations on each wheel hub to collect real-time temperature data. The digital temperature sensor features a self-test function, automatically detecting its own operational status to ensure accurate and reliable temperature data, with measurement errors controlled within ±1℃. Furthermore, the sensor and connecting cables are made of high-temperature and corrosion-resistant materials, enabling them to withstand harsh environments such as high and low temperatures, dust, and humidity during vehicle operation, ensuring long-term stable operation and preventing monitoring failures due to environmental factors.
[0023] II. Control Module The control module is the core of the entire system, electrically connected to the temperature acquisition module, display module, early warning module, and water spray linkage module. It receives real-time temperature data from the temperature acquisition module, analyzes and processes the data, and determines whether the wheel hub temperature is within the normal range, whether it has reached the early warning threshold, and whether the water spray start / stop threshold has been reached. The control module has built-in preset threshold parameters, including an early warning threshold, an upper limit threshold for water spray start, and a lower limit threshold for water spray stop. The early warning threshold is set to 85℃, the upper limit threshold for water spray start can be preset to 60℃ (adjustable according to actual vehicle conditions), and the lower limit threshold for water spray stop can be preset to 40℃ (adjustable according to actual vehicle conditions). Based on the comparison between the temperature data and the preset thresholds, the control module sends corresponding control commands to the display module, early warning module, and water spray linkage module to achieve coordinated operation of each module.
[0024] III. Display Module The display module uses an LCD screen, which is electrically connected to the control module. It receives wheel hub temperature data and status commands transmitted by the control module and displays the current temperature of each wheel hub in real time. When the temperature of a wheel hub exceeds the warning threshold (85℃), the control module sends a command to the display module, and the display icon corresponding to that wheel hub turns red, intuitively reminding the driver that the wheel hub temperature is abnormal. At the same time, the display module synchronously displays the warning status and the working status of the water spray system, ensuring that the driver can keep track of the system operation and wheel hub temperature changes in real time.
[0025] IV. Early Warning Module The early warning module uses an audible and visual alarm device, which is electrically connected to the control module. It receives early warning commands from the control module and issues audible and visual warning signals. When the wheel hub temperature reaches the early warning threshold (85℃), the control module sends an early warning command, and the early warning module is activated, issuing an audible and visual alarm every 3 minutes until the wheel hub temperature drops below 85℃. If the driver ignores the warning and the wheel hub temperature continues to rise, the control module will control the early warning module to adjust the alarm frequency, issuing an audible and visual alarm for every 1℃ increase. No new alarm will be triggered when the temperature drops. If the temperature continues to remain above 85℃, an alarm will still be triggered every 3 minutes to ensure that the driver can pay attention to the high temperature risk in time and take appropriate measures.
[0026] V. Water Spraying Linkage Module The water spray linkage module interfaces with the vehicle's existing water spray system, and its start and stop are controlled by the control module to achieve automatic water spray cooling of the wheel hubs. When the vehicle is equipped with a water spray system, the control module determines whether the wheel hub temperature has reached the upper limit threshold for water spray activation (e.g., 60°C) based on the temperature data transmitted by the temperature acquisition module. If the threshold is reached, the control module sends a start command, and the water spray linkage module triggers the water spray system to start, spraying cooling water onto the high-temperature wheel hubs to quickly reduce the wheel hub temperature. When the wheel hub temperature drops to the lower limit threshold for water spray shutdown (e.g., 40°C), the control module sends a shutdown command, and the water spray linkage module triggers the water spray system to shut down, avoiding excessive water spraying and wasting water resources, while ensuring precise control of the cooling effect.
[0027] VI. System Workflow The workflow of this system follows the logic of data collection, analysis, judgment, and execution, forming a complete closed loop, as detailed below: Step 1: After the vehicle is started, the temperature acquisition module is activated, and the digital temperature sensor begins to collect the temperature data of each wheel hub in real time and transmits the collected temperature data to the control module in real time; at the same time, the sensor performs a self-check, and if a fault is found, it will promptly alert the driver through the display module. Step 2: After receiving the temperature data, the control module analyzes and processes the data, compares the real-time temperature with the preset warning threshold and water spray start / stop threshold, and determines the wheel hub temperature status. Step 3: The control module transmits real-time temperature data and temperature status to the display module, which displays the temperature of each wheel hub and the system's operating status in real time. Step 4: If the wheel hub temperature does not exceed any preset threshold, the system maintains normal monitoring and continues to collect temperature data; Step 5: If the wheel hub temperature reaches the warning threshold (85℃), the control module immediately sends a warning command to the warning module and an abnormal display command to the display module. The display module will turn the corresponding wheel hub icon red, and the warning module will issue an audible and visual alarm every 3 minutes. If the temperature continues to rise, the warning module will issue an audible and visual alarm for every 1℃ increase. If the temperature drops, no new alarm will be triggered. If the temperature remains above 85℃, an alarm will be triggered every 3 minutes. Step 6: If the vehicle is equipped with a water spray system, when the wheel hub temperature reaches the upper limit threshold for water spray activation (e.g., 60℃), the control module sends a start command to the water spray linkage module, and the water spray system is activated to cool the wheel hub with water. Step 7: After the water spray system is turned on, the temperature acquisition module continuously collects wheel hub temperature data, and the control module monitors temperature changes in real time. When the temperature drops to the lower limit threshold for water spray shutdown (e.g., 40℃), the control module sends a shutdown command to the water spray linkage module, and the water spray system is turned off. Step 8: Until the wheel hub temperature is lower than the warning threshold (85℃), the warning module stops alarming, the display module resumes normal display, the system returns to normal monitoring state, and the above steps are repeated.
[0028] In this embodiment, the present invention operates as follows: After the vehicle is started, the system automatically powers on, and the temperature acquisition module starts up. The digital temperature sensor corresponding to each wheel hub begins to collect the temperature data of its own wheel hub in real time. At the same time, the sensor automatically performs a self-test. If the sensor is working properly, the display module will display the current temperature of each wheel hub in real time. The normal temperature is usually 30-50℃. If a sensor malfunctions, the display module will promptly alert the driver to the corresponding wheel hub sensor failure, reminding them to have it inspected and repaired in a timely manner. When the vehicle enters a long downhill section or other conditions requiring frequent braking, the heat generated by the braking system is transferred to the wheel hub, causing the wheel hub temperature to gradually rise. The temperature acquisition module continuously transmits the real-time temperature data to the control module.
[0029] The control module analyzes and processes the received temperature data, comparing it with built-in preset thresholds. When the temperature of a wheel hub rises to the upper limit threshold of 60°C for water spray activation, the control module immediately sends a start command to the water spray linkage module, controlling the solenoid valve of the water spray system to open. The water spray nozzles then spray cooling water onto the high-temperature wheel hub, achieving automatic cooling. After the water spray system is activated, the temperature acquisition module continuously collects the temperature data of the wheel hub, and the control module monitors temperature changes in real time. If the temperature continues to rise and is not effectively controlled, reaching the warning threshold of 85°C, the control module sends a warning command to the warning module and simultaneously sends an abnormal display command to the display module. The icon corresponding to the wheel hub in the display module automatically turns red, and the warning module begins to issue an audible and visual alarm every 3 minutes.
[0030] If the driver does not handle the situation in time, causing the wheel hub temperature to continue to rise, the control module will control the warning module to issue an audible and visual alarm for every 1°C increase. No new alarm will be triggered when the temperature drops. If the temperature continues to remain above 85°C, an audible and visual alarm will still be triggered every 3 minutes until the temperature drops below 85°C.
[0031] When the water spray system continues to work and the wheel hub temperature gradually decreases to the lower limit threshold of 40°C for water spray shutdown, the control module sends a shutdown command to the water spray linkage module, the solenoid valve closes, and the water spray system stops working to avoid water waste.
[0032] When the wheel hub temperature continues to drop below 85°C, the control module sends a stop alarm command to the early warning module. The early warning module stops the alarm, the icon of the wheel hub in the display module returns to its normal color, and the system returns to normal monitoring status, continuously collecting temperature data of each wheel hub and repeating the above process.
[0033] If a single wheel hub is detected to have an abnormal temperature rise exceeding 85°C, while the temperatures of other wheel hubs remain normal, the display module will only turn the icon of the abnormal wheel hub red. The warning module will then trigger an alarm for that abnormal wheel hub, and the water spray system will only spray water to cool it down, achieving precise control. At the same time, the driver will be reminded to check the braking system and water spray nozzles of that wheel hub for faults such as improper brake adjustment or nozzle blockage, to avoid safety accidents caused by abnormalities in a single wheel hub.
[0034] The following are several other specific embodiments of the application of this invention: Example 1 (I) System Composition and Installation The intelligent water spray cooling control system for vehicle wheel hub temperature monitoring in this embodiment includes a temperature acquisition module, a control module, a display module, an early warning module, and a water spray linkage module. The specific components and installation method are as follows: 1. Temperature acquisition module: DS18B20 digital temperature sensor is used (for example only, sensor model is not limited). One sensor is installed for each wheel hub. The sensor is connected to the control module through high temperature and corrosion resistant cable. During installation, the sensor is placed near the brake drum of the wheel hub to ensure accurate acquisition of wheel hub temperature. The cable is protected to avoid wear and aging during driving. 2. Control Module: An STM32 series microcontroller (for example only, controller model not limited) is used. It is installed in a suitable position in the vehicle cab and is electrically connected to the temperature acquisition module, display module, early warning module, and water spray linkage module via wiring. It has built-in preset thresholds: early warning threshold 85℃, water spray start upper limit threshold 60℃, and water spray shut-off lower limit threshold 40℃. It supports manual adjustment of thresholds to adapt to different vehicle operating conditions. 3. Display module: A 5-inch LCD screen is installed near the dashboard in the cab and is electrically connected to the control module. It can clearly display the real-time temperature, warning status, and water spray system working status of each wheel hub. When the temperature of a wheel hub exceeds 85℃, the corresponding icon will automatically turn red. 4. Warning module: It adopts an audible and visual alarm, which is installed in the cab and electrically connected to the control module. The alarm sound is no less than 80dB and the light flashes red to ensure that the driver can notice it in time. 5. Water Spray Linkage Module: Connects to the solenoid valve of the vehicle's existing water spray system. The control module controls the start and stop of the solenoid valve, and the water spray nozzles are aimed at the high-temperature areas of each wheel hub to ensure the targeted and effective cooling effect.
[0035] (II) System Working Process In this embodiment, the invention operates as follows: After the vehicle starts, the system automatically powers on, and the temperature acquisition module activates. The digital temperature sensor corresponding to each wheel hub begins collecting its own temperature data in real time. Simultaneously, the sensor performs an automatic self-check. If the sensor is functioning correctly, the display module will show the current temperature of each wheel hub in real time; the normal temperature is typically 30-50°C. If a sensor malfunctions, the display module will promptly indicate the sensor failure for the corresponding wheel hub, reminding the driver to have it repaired. When the vehicle enters a long downhill section or other conditions requiring frequent braking, the heat generated by the braking system is transferred to the wheel hubs, causing their temperature to gradually rise. The temperature acquisition module continuously transmits the rising temperature data to the control module. The control module analyzes and processes the received temperature data, comparing it with a built-in preset threshold. When the temperature of a wheel hub rises to the upper limit threshold of 60°C for water spray activation, the control module immediately sends a start command to the water spray linkage module, controlling the solenoid valve of the water spray system to open, and the spray nozzles spray cooling water onto the high-temperature wheel hub to achieve automatic cooling. After the water spray system is activated, the temperature acquisition module continuously collects temperature data from the wheel hub, and the control module monitors temperature changes in real time. If the temperature continues to rise and is not effectively controlled, reaching the warning threshold of 85℃, the control module sends a warning command to the warning module and simultaneously sends an abnormal display command to the display module. The icon corresponding to the wheel hub in the display module automatically turns red, and the warning module begins to issue an audible and visual alarm every 3 minutes. If the driver does not take timely action, causing the wheel hub temperature to continue to rise, the control module will control the warning module to issue an audible and visual alarm for every 1℃ increase. No new alarms are triggered when the temperature drops. If the temperature remains above 85℃, an audible and visual alarm will still be triggered every 3 minutes until the temperature drops below 85℃. When the water spray system continues to operate and gradually lowers the wheel hub temperature to the water spray shutdown threshold of 40℃, the control module sends a shutdown command to the water spray linkage module, the solenoid valve closes, and the water spray system stops working to avoid water waste. When the wheel hub temperature continues to drop below 85℃, the control module sends a stop alarm command to the warning module. The warning module stops the alarm, the icon for that wheel hub in the display module returns to its normal color, and the system returns to normal monitoring status, continuously collecting temperature data for each wheel hub and repeating the above process. If a single wheel hub temperature is detected to abnormally rise above 85℃ while other wheel hub temperatures are normal, the display module will only turn the icon for the abnormal wheel hub red. The warning module will trigger an alarm for that abnormal wheel hub, and the water spray system will only spray water to cool it down, achieving precise control. At the same time, it reminds the driver to check the braking system and water spray nozzles of that wheel hub for faults such as improper brake adjustment or nozzle blockage, to avoid safety accidents caused by abnormalities in a single wheel hub.
[0036] Example 2 (I) System Composition and Installation The intelligent water-spraying cooling control system for vehicle wheel hub temperature monitoring in this embodiment is adapted to light trucks. Its core components are the same as those in Embodiment 1, but the specific components and installation method are adjusted as follows: 1. Temperature acquisition module: The SHT30 digital temperature sensor is used, with one sensor configured for each wheel hub. The sensor adopts a waterproof and sealed structure and is installed on the inside of the wheel hub spokes. It is connected to the control module through a high-temperature resistant silicone cable. The cable length is adapted to the wheel hub spacing of light trucks, and the outer layer is wrapped with an anti-wear sleeve to adapt to the vibration environment during the operation of light trucks. 2. Control module: It adopts the MSP430 series microcontroller, which is small in size and installed inside the center console of the cab. The built-in preset thresholds can be manually adjusted through the vehicle touch panel. The default warning threshold is 80℃, the upper limit threshold for water spray start is 55℃, and the lower limit threshold for water spray shutdown is 35℃, which is adapted to the brake heat dissipation characteristics of light trucks. 3. Display module: It adopts a 3.5-inch OLED display screen, which is embedded in the cab instrument panel. It has low power consumption and clear display. It can switch between two modes: full-screen temperature display and single wheel hub focus display. When the wheel hub temperature exceeds the warning threshold, the display screen automatically switches to the focus display interface of the corresponding abnormal wheel hub and flashes to prompt it. 4. Warning module: It adopts an integrated sound and light alarm horn, which is installed on the top of the cab. The alarm sound is 75dB (suitable for the cab space of light trucks), the light is flashing yellow, and at the same time, it is linked to the vehicle central control to emit a vibration prompt, so as to avoid the driver noticing the warning due to noise. 5. Water Spraying Linkage Module: Connects to the small water spray tank and micro water pump that come with the light truck. The control module controls the water spraying by controlling the start and stop of the water pump. The water spray nozzles are atomizing nozzles and are installed inside the wheel hub to reduce water consumption and improve the uniformity of cooling.
[0037] (II) System Working Process In this embodiment, the invention operates as follows: After vehicle startup, the system automatically completes a self-check. The temperature acquisition module starts and collects real-time temperature data for each wheel hub. The display module displays a full-screen temperature interface by default. Under normal operating conditions, the wheel hub temperature is maintained between 25-45℃. When the vehicle is driving on mountainous roads, frequent braking causes the wheel hub temperature to rise. The temperature acquisition module transmits the temperature data to the control module in real time. The control module compares the data with a preset threshold. When the temperature of a certain wheel hub reaches 55℃, it immediately controls the water spray linkage module to start the micro water pump, and the atomizing nozzle sprays atomized cooling water onto the wheel hub to quickly reduce the wheel hub temperature. If the temperature continues to rise to the 80℃ warning threshold, the display module automatically switches to the display interface for the abnormal wheel hub, and the warning module issues an audible, visual, and vibration warning every 3 minutes. If the temperature continues to rise, an alarm is triggered for every 1℃ increase. When the temperature drops, new alarms are stopped. If the temperature remains above 80℃, an alarm is repeated every 3 minutes. When the wheel hub temperature drops to 35℃, the control module shuts off the micro water pump, and the water spray system stops working. When the temperature drops below 80℃, the warning module stops alarming, the display module resumes full-screen temperature display, and the system continues to monitor continuously. If a sensor malfunction is detected, the display module will pop up a fault message box, clearly indicating the wheel hub location corresponding to the faulty sensor, facilitating quick repair by the driver.
[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
