At the meeting, Fang Chao, the project leader of China National Control Information Corporation, first gave a detailed report. The expert group listened carefully to the report and checked the project construction item by item. The expert group believes that this project is in the forefront of Henan province in terms of innovative technology and construction process quality. Many of these projects are the first applications in the country. The expert group also stated that the project can create a demonstration project in the province and serve as a replicable landmark construction template. The relevant materials will be submitted to the Public Security Department of Henan Province. Finally, the expert group unanimously agreed that the project passed the preliminary inspection.
The second phase project of “Tianyan†project of Linzhou City was formally started on June 18, 2016. It lasted five months and completed the construction of the 14th National System on November 14th. The first project is the use of high-definition video surveillance, are star-class night visual high-definition camera, to solve the problem of poor night performance; Second, Hongqiqu Avenue new national standard electronic police using infrared light mode, is a new technology application; It realizes the networking and coordination of intelligent traffic signal control systems in urban areas, and realizes green wave coordination control and regional coordination control in some road sections. Fourth, it is a pedestrian-based red light supervision system that leads nationwide. It adopts full-color information screens to solve the problem of insufficient brightness, and is equipped with voice. The prompt function is the first case in the province. Fifth, the use of virtualized cloud computing systems in the field of public security video surveillance is the first case in Henan. Sixth, it is a national initiative to increase the number of measures in combination with safety. Seventh, the cloud-eye big data system has greatly improved the daily work efficiency and has demonstrated great results in the public security industry. In this regard, the expert group gave a high evaluation.
The second phase project of the “Tianyan†project in Linzhou City is a typical case of Central Control Information Corporation in the safe city of Henan Province and the smart transportation sector. Central Control’s technical service level in system integration, smart public security, and smart transportation has won Linzhou. The municipal government and the relevant competent authorities in Henan Province are highly recognized.
(Original title: Linzhou City "Tianyan" project passed the preliminary inspection successfully)
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.
(3) With the function of inching during operation, realize the accuracy.
(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
