Product Description: This control board comes with a high-speed control chip that performs conversion of externally input DC 0-5V analog voltage, then controls the output pulse frequency based on the voltage level (with precision as high as 1Hz depending on the output frequency range). The output frequency range corresponding to the 0-5V input can be flexibly configured via the RS232 serial port (for example, 0-5V input can correspond to 0-1000Hz output; 0-5V input can correspond to 0-120,000Hz output; or 0-5V input can correspond to 0-1024Hz output, etc.). The maximum output pulse frequency can reach 200kHz (higher frequencies can also be customized).The output frequency is calculated as follows:Fout = (Vin ÷ 5) × FmaxWhere: Fout - frequency of the output pulse signal; Vin - current input voltage; Fmax - maximum output frequency corresponding to 5V voltage.If the maximum output frequency corresponding to 5V voltage is set to 1000 Hz, then with an input voltage of 2.5V, the output frequency is Fout = (2.5 ÷ 5) × 1000 = 500 Hz;If the maximum output frequency corresponding to 5V voltage is set to 120,000 Hz, then with an input voltage of 2.5V, the output frequency is Fout = (2.5 ÷ 5) × 120,000 = 60,000 Hz;If the maximum output frequency corresponding to 5V voltage is set to 1024 Hz, then with an input voltage of 2.5V, the output frequency is Fout = (2.5 ÷ 5) × 1024 = 512 Hz;The converted voltage and frequency values can be directly read via the serial port.This board can be widely used in various industrial automation applications requiring voltage/frequency conversion, replacing traditional analog voltage-frequency conversion devices. It offers advantages such as full digitalization, minimal parameter drift, low discreteness, and excellent linearity across the entire frequency output range. more>

Product Description: Airport Localizer Beacons, 3-meter frangible masts, 5-meter wind sock frangible masts, and 12-meter frangible monitoring light poles are all specialized airport facilities designed to be frangible or breakaway. The core design objective is to absorb impact energy through their own fracture or deformation in the event of an accidental aircraft collision, thereby reducing damage to the aircraft structure and injuries to personnel, while maintaining the basic functionality of airport ground equipment. Below is a detailed introduction:I. Core Design Principle: Balancing Frangibility and FunctionalityThe key characteristic of frangible/breakaway masts is **"directional fracture"**—when subjected to a specific impact force (typically ≤20kN, complying with ICAO standards), the mast or its connection points fracture along a predetermined path rather than resisting rigidly. At the same time, they must meet structural strength requirements for daily use, withstand natural loads such as wind, rain, and snow, and ensure the stable operation of equipment (e.g., beacons, wind socks, monitoring lights).II. Types and Application Scenarios1. Airport Localizer Beacon Frangible MastFunction: Supports localizer beacon equipment (a radio navigation facility for guiding aircraft during approach and landing), installed at critical navigation areas at runway ends or alongside.Frangibility Design: The mast typically features a segmented structure with frangible joints (e.g., thin-walled aluminum alloy connecting sections, specialized shear bolts) at the base or middle. During a collision, the joints fracture first, preventing the beacon equipment from being forcibly pulled and damaged, while reducing reactive forces on the aircraft.Specifications: Height is customized based on beacon installation requirements (usually 3–8 meters), with materials often being lightweight high-strength aluminum alloy or fiberglass composite, balancing corrosion resistance and frangibility.2. 3-Meter Frangible MastApplication: Commonly used to support small airport ground equipment, such as runway edge lights, taxiway marker lights, and small meteorological sensors, installed in low-risk collision areas (e.g., runway edges, apron peripheries) where aircraft taxi, take off, or land.Features: Slim mast diameter (50–100mm), made of fiberglass-reinforced plastic (FRP) or modified PVC, offering some flexibility to bend and break upon impact, with no sharp edges after fracture.3. 5-Meter Wind Sock Frangible MastFunction: Supports wind socks (meteorological equipment indicating wind direction and speed), typically installed at runway ends, aprons, or open areas along airport boundaries.Frangibility: The mast is made of low-strength aluminum alloy or degradable composite materials, designed to fracture brittly at the middle or base when subjected to lateral forces (e.g., aircraft wing collision), preventing the wind sock and支架 from entangling aircraft components.Structural Advantage: Lightweight top (wind sock weight ≤1kg), base fixed with anti-pullout design (stable for daily use), with post-fracture residual height ≤30cm, meeting airport obstacle-free requirements.4. 12-Meter Frangible Monitoring Light PoleApplication: Used to support perimeter surveillance cameras and high-altitude lighting fixtures, installed inside airport fences or at remote runway areas requiring broad monitoring/illumination.Frangibility Design: Employs a **"rigid top, flexible bottom" segmented structure**—upper section (8–10 meters) made of high-strength steel (ensuring equipment stability), lower section (2–4 meters) with a frangible segment (e.g., thin-walled steel tube + shear pin connection). Upon impact, the lower section fractures first, causing the upper structure to topple entirely (rather than rigidly resisting), reducing impact force on the aircraft.Additional Features: Some models integrate lightning protection grounding systems, with surface anti-corrosion treatment (suitable for outdoor airport environments). The frangible segment can be quickly replaced after fracture, minimizing equipment downtime.III. Key Technical StandardsInternational Standards: Complies with ICAO "Annex 14 to the Convention on International Civil Aviation" requirements for frangible equipment, stipulating that masts must fracture below 1.5 meters height under impact forces ≤22kN, with residual parts posing no hazardous obstruction.Domestic Standards: Follows GB 500014-2021 "Technical Standards for Civil Airport Airfield Areas," specifying parameters such as material strength, fracture load, and installation height for frangible masts to ensure alignment with airport airfield safety levels.IV. Core AdvantagesSafety: Through preset fracture point design, minimizes damage risk during aircraft collisions, making them essential safety facilities in airport "low-risk collision zones."Practicality: Balances equipment support functionality with environmental adaptability (wind resistance, corrosion resistance, weather resistance), meeting 24/7 airport operational needs.Maintainability: Frangible segments are standardized components, allowing quick replacement after fracture with low repair costs and no disruption to normal airport operations. more>

Product Description: Both Q420B and Q420NB are steel grades defined by the Chinese national standard GB/T 1591-2018 "High Strength Low Alloy Structural Steels." Their main differences lie in the delivery condition and the possible rolling processes involved.Q420B:"B" indicates the quality grade of the material, typically associated with impact testing at -20°C.The delivery condition for Q420B is usually in the as-rolled state, meaning the steel is cooled directly after rolling without subsequent heat treatment processes.The hot rolling process helps achieve a fine grain structure, improving the material's strength and toughness.Hot-rolled Q420B may not undergo normalizing treatment, so the grain size may be coarser compared to that of normalized or thermomechanically controlled processed (TMCP) steel.Q420NB:"NB" indicates that the material is delivered in a normalized or normalized rolled condition. "N" stands for normalized, and "B" represents the quality grade, associated with impact testing at 20°C.Normalizing treatment involves heating the steel to a certain temperature, holding it, and then cooling it to improve the grain structure, enhancing plasticity and toughness.Q420NB may undergo a normalized rolling process, where normalizing is performed during rolling, helping refine the grain and improve the material's impact toughness.Comparison of Rolling Processes:Hot Rolling Process (Q420B):Steel is rolled at high temperatures and then cooled naturally or under controlled conditions to form the desired shape and dimensions.The hot rolling process improves production efficiency and reduces energy consumption.Hot-rolled materials have higher hardness and strength but may have slightly lower plasticity compared to normalized materials.Normalized Rolling Process (Q420NB):During rolling, the steel undergoes normalizing treatment to improve its mechanical properties and processability.Normalizing can reduce internal stresses generated during rolling and improve the material's uniformity.Normalized rolled materials typically exhibit better weldability and processability.In practical applications, the choice between Q420B and Q420NB depends on the requirements of the final product. If higher strength and hardness are needed, Q420B may be selected; if better toughness and weldability are required, Q420NB may be preferred. Additionally, normalizing treatment may increase production costs, so hot-rolled materials might be prioritized in cost-sensitive applications. During the design and manufacturing process, engineers need to select the appropriate material and process based on specific application needs and cost-effectiveness analysis.High-strength coil3.75mmQ420NB0.01500.0128.900High-strength coil3.75mmQ420NB0.01500.0128.710High-strength coil3.75mmQ420NB0.01500.0128.770High-strength coil3.75mmQ420NB0.01500.0128.780High-strength coil3.75mmQ420NB0.01500.0128.820High-strength coil3.75mmQ420NB0.01500.0128.550High-strength coil3.75mmQ420NB0.01500.0128.450High-strength coil3.75mmQ420NB0.01500.0127.530High-strength coil3.75mmQ420NB0.01500.0128.510High-strength coil3.75mmQ420NB0.01500.0128.120 more>

Product Description: Northern corn leaf blight is a common disease in corn, caused by Exserohilum turcicum, which damages leaf sheaths and husks. It typically starts from the lower leaves and gradually spreads upward. In severe cases, it can affect the entire plant, though there are instances where it begins on the middle or upper leaves.Therefore, in the process of corn cultivation, monitoring and early warning of northern corn leaf blight are urgently needed. With the strong support from the government for high-standard farmland, many IoT devices have been put into use, making monitoring and early warning more intelligent. Among them, the spore trap is primarily developed for plant disease monitoring.So how does the spore trap monitor northern corn leaf blight? This starts with the working principle of the spore trap. During the corn growing season, overwintering pathogens produce spores, which are dispersed into the air by wind currents. These fungal spores are extremely tiny, lightweight, and difficult to observe with the naked eye.The spore trap effectively captures these minuscule fungal spores. It operates on aerodynamic principles, using a fan to draw in spores that are hard to see with the naked eye. Once captured, the spores are adsorbed onto a slide belt. An internal camera and high-powered microscope then photograph the captured spores and upload the images to an IoT platform. The spore images are clear and visible, allowing the system to perform automatic statistical analysis. Staff can monitor the situation of northern corn leaf blight spores anytime and anywhere.The deployment of spore traps greatly facilitates plant protection personnel in monitoring and early warning of northern corn leaf blight. It enables timely preventive measures, improves control effectiveness, and ensures increased yield and production for crops. more>
