Highway electronically directed warning sign
â–²High I Wang Zhaosu Corridor â–¡ Wang Zhaoguo's road construction is moving forward at a speed of a thousand miles. Investment in transportation facilities is on the rise. The electronically-oriented warning i-card is receiving more and more attention from road operators and public security traffic control departments. Keeping the smooth flow of highways, reducing the accidents and casualties of roads, and adopting advanced road-oriented warning means are gradually becoming the consensus of all relevant departments. The traffic police department can also use it for guided vehicles, wreckers, accident handling vehicles, traffic signal installation and replacement engineering vehicles, and so on. The advanced and reasonable warning signs must have the following characteristics: the warning orientation is diverse, flexible, vivid and rich; the warning content is eye-catching and eye-catching, and the high-speed vehicles should be clearly visible 100 meters away, regardless of whether Sunny, cloudy or foggy, rainy days; the guide card must be light, at the same time strong and sturdy and extremely easy to install; the use should be simple and easy to learn. People with a primary education can learn to use it in a matter of minutes. It should be powered by the car battery. The power consumption should be very low to adapt to long-term parking operations in the field or slow driving operations such as sweeping and watering. Recently, electronically-oriented warning signs designed and produced in accordance with developed country specifications have appeared on the expressways of the Pearl River Delta in Guangdong. This kind of warning sign produced by Guangzhou Qingsong Technology Co., Ltd. is usually installed on the back of the engineering or work vehicle. It has more than 10 running, flashing and long lighting. Moderator: Xu Wei â–¡ News Hotline The old winter shows the way to the police spear card. It is powered by a car battery, the controller is small and exquisite, and it is very simple and convenient to install in the cab. It has brightness adjustment to ensure that it can be seen at very long distances in strong sunlight, while at night, it can be turned down to ensure that it is not too bright and not glare. It also has a low voltage warning to ensure that it does not drain the battery power. Its price is about one-third that of imported similar products. Electronically guided cards are usually mounted on the rear of the vehicle and powered by a car battery. Since the warning guide card actively emits light, the warning guidance effect on the rear car is very good. Using light-emitting diodes as light source, energy consumption is 80%-90% lower than ordinary light bulbs. Product consultation telephone: Guangzhou Qingsong Technology Co., Ltd. 13809215354 This machine is a non-contact 1C card high-speed data reading and writing, mechanical automatic transceiver card, semi-closed Card-box management and other functions in one computer-controlled high-tech products. It is mainly used to realize the issuance and recycling of 1C card for idle highway lanes or parking lots, which can effectively prevent 1C card loss and charge cheating. Compared with the same type of products at home and abroad, the machine has a small card surface wear and tear, and sells the Chinese public bus transportation product and the Changlu Highway S. The long-distance investment of the expressway is developed by Xiaoxiang Network Technology Development Co., Ltd. The 1C card automatic card transceiver was put into trial operation on the Changsha National Highway around the city. The success of the trial operation has greatly improved the localization rate of China's idle speed toll system. Low price and other advantages. Its built-in Mifare system non-contact 1C card reader module and antenna can automatically identify the authenticity of the 1C card, and automatically read and write the idle data of the Mifare series of non-contact 1C cards. At the same time as the card is sent and received, the remaining number and number of changes in the card box are automatically detected and reported. In addition, the machine has a unique card box management function. The traditional card management is changed to card box management, and each card box has a card box management card that records information such as card box number and card number. The 1C cards in the card box are stored in the order of the numbers written in the card. Each time a 1C card is received or sent, the relevant information is sent to the upper computer. Anyone without permission can't get in touch. The workload of the 1C card inventory is greatly reduced, and the loss of the card is reduced. In addition, the standard RS232 serial interface of the machine can be operated online with the upper computer, and it can detect and adapt itself at the communication baud rate (9600bps 115.2kbps). At the same time, according to the command of the upper computer to transmit, the corresponding operations of receiving, sending, reading, writing, and changing the card box are executed and the execution result is uploaded to the upper computer. The card's jacking "constant force control" mode has a simple structure and is easy to debug and repair. On June 25, 2001, the aircraft passed the appraisal of scientific and technological achievements hosted by the Science and Technology Department of Hunan Province. Nine experts, including Academician Sha Qinglin, an academician of the Chinese Academy of Engineering, gave a high evaluation of the machine. It is unanimously recognized that the lifting mechanism of the spring weight "constant force control" mode has been adopted for the first time in the same kind of products at home and abroad, which improves the reliability; through the electromechanical automatic control, non-contact 1C card data reading and writing functions, etc. The contact type 1C card transceiver process is automated, which shortens the time of sending and receiving cards. Its comprehensive technical performance is domestically leading, and it is recommended to actively promote products. At present, the aircraft has obtained two national utility model patents and was rated as a high-tech product in Hunan Province.
