Supply speed feedback device LLCSP, speeding red, not green overspeed

This product is our company developed a driver to reduce the driving speed, improve traffic safety in transportation. This product has been more popular in foreign countries. The product has two solar power and general power. Our company is the first domestic production of the product design of the unit, from 2006 began to promote the product since the product in the domestic field has a place. The product can be used in the following locations: 1 / residential area 2 / parking parking lots: 3 / Speedway: 4 / general road: 5 / Plant: 6 / construction sites 7 / mining or rail transport Area: 8 / accident-prone Lot (such as corners; tunnels; bridges) 9/10 school districts / hospital area can be used in short everything to improve public safety. ? Technical Data Font: height: 35 cm color: color: red or yellow color: green for safe speed; red for speeding Number:?? Two characters or three characters Screen size: 40 * 70 cm box size: 80 * 55 * 7 cm and a thickness of 7 cm board (three digits) Size: 69 * 114 cm LED: Brightness: Red:? 5000-7000mcd; yellow 6000-8000mcd; green 10000-12000mcd angle: Red: 30 degrees? ; yellow: 30 degrees; Green:???? 45 degrees radar: K-wave directional Doppler radar monitoring range: four-lane speed range: 5 --- 321 km / h error: 1-2 km / h transmission ? mode: RS232 interface to a series of reaction time: ≤5ms communication protocols (between the controller and the screen): I2C protocol Power input: 90-240V AC operating voltage: 12V DC Current consumption: Max: 10W; Standby: 0.2W; Battery: 12V 65AH; 21 kg / only Weight: 40 kg ordinary solar energy solar panel 20 kg: 12V 40W; 12V 80W flag Reflective Film: High Strength Operating Temperature: -40 ℃ --- 70 ℃ ° Manufacturer: Hangzhou to Lai Technology Co., Ltd. through CE / FCC / ROHS certification Every day thousands of pedestrians, cyclists and road construction workers and car joint use of roads. The elderly, young people, and children, both walk to work, or to school, they need a safe road traffic environment. Product demand inevitability: 1. In recent years, statistics found that the faster the car, the more likely lead to heavy casualties in a pedestrian accident. 2. Clearly, relying on speed limit signs, has been unable to meet the needs of traffic safety. Studies have shown that the speed feedback signs can be effectively reduced vehicle speed. Product function: to achieve by microwave radar speed, real-time feedback to the vehicle speed and the driving speed of change, remind drivers not to speed, and the speed down to a safe range, thereby improving pedestrian safety. Product advantages - our commitment to: 1. Applicable to different needs, good durability; 2. We produce a speed feedback signs have good sealing performance, simple installation, easy to replace, and can be easily removed from the surface of the blot without surface damage marks; 3. In order to ensure better use of signs, we can have two years to replace the defective part free of charge, to a greater extent to ensure that the mark time; 4. We offer different types of size and display a high degree of speed feedback signs, users can also choose the type of power according to different needs. In particular, some special circumstances, we can provide solar power systems for suitability of the product provides a wider choice. Components: 1. Speed ??limit signs (indicating speed limits of the road) 2. Such as "Please note that your speed" message alerts and a dynamic LED (conductor light emitting diode) displays, data showing changes through time above the speed of the vehicle 3. Microwave radar three control flag operation: 1. Normally open 2. 3 by manual switch. Improve software pre-conditions to operate. When the vehicle speed exceeds the set value, the "speed feedback signs" would be a way through a flashing LED to warn drivers. How it works: (approximately mark the front of the range of 500m to 10m), microwave radar will automatically detect vehicle speed, and displayed on the LED display when the vehicle enters "speed feedback signs" timely detection area radar to alert the driver to reduce speed, so as to effectively reduce road traffic accidents caused by speeding. Speed ??feedback signs induce a significant striking feature, it can significantly reduce traffic accidents, to secure results. Companies in strict accordance with ISO9001: 2000 international quality management system for production management, strictly in production, at present, the company has design, development and production and marketing capacity speed feedback signs tens of thousands, and the development and production of products with domestic sales target road construction, traffic management and police departments and other units, the products have been exported abroad, exported to the United States, Britain, Australia, Mexico, Arab and other countries and regions. Product Installation Instructions 1. The solar panel is fixed to the bracket and fixed with screws and nuts on the vehicle speed feedback signs with white wire to the solar panels and the vehicle speed feedback signs inside the battery connector on the positive and negative one to one connection. 2. The speed feedback sign fixed left or right side of the road, or the road, just above the mouth so that the radar is on to drive the direction of the inclination angle of not more than 15 degrees above the road if it is fixed, the position should be fixed radar radar Muzzle oblique angle aligned to drive position. At the same time, the higher range radar and the ground, the farther away from the radar work. Generally keep the distance from the ground radar at 2-7 meters better. 3. Open the rear vehicle speed feedback signs, radar data lines, control board wiring correspondence connection. After adjusting the radar position so positive to come from the direction of the car. 4. Screw the speed feedback signs attached to ram the vehicle speed feedback signs over the top post.
