Talking about the installation precautions of road monitoring poles Solar street light-litersolar production

Monitoring on the road is essential, so this article will introduce to you the precautions for the installation of road monitoring poles. Road camera pole The pole requires that the height of the camera from the ground is generally not less than 5 meters, the length of the pick arm is 3 to 5 meters, the diameter of the lower end of the pole should be 220 mm ± 10 mm, and the surface is anti-corrosion and typhoon resistance. The foundation depth of the vertical pole is not less than 1.5 meters, the diameter of the foundation is more than 1 meter, and the concrete is poured to ensure the firmness of the vertical pole. Talking about the installation precautions of road monitoring poles 1. The outdoor chassis structure is designed as an outdoor rainproof box. The height of the chassis is 0.8 meters, the width is 0.6 meters, and the thickness is 0.45 meters. The enclosure protection grade reaches IP54 protection grade. It needs to have a chassis foundation, the overall appearance is beautiful, the surface is sprayed with obvious warning signs, and the height of the chassis from the ground is not less than 30 cm). 2. An optical transceiver and monitoring power supply should be installed in the outdoor chassis. Among them, the optical transceiver adopts 1V+1D (one video + one reverse data) single-channel optical transceiver, with FC/ST interface, transmission distance: 0-30KM; optical wavelength is 1310/1550nm, frequency response 5Hz ~ 8MHz, video format compatible with PAL , NTSC, SECAM, signal-to-noise ratio ≥ 70dB, voltage 1Vp-p 75Ω, video interface BNC, 8-bit linear digital PCM encoding; data RS-232, RS-422, RS-485 optional, bit error rate less than 10- 9; Reserved voice interface, with network management function. And the chassis and pole are unified lightning protection grounding. 3. Lightning protection and grounding of front-end equipment. As we all know, lightning is extremely destructive, with voltages as high as millions of volts and instantaneous currents as high as hundreds of thousands of amperes. The destructive consequences caused by lightning strikes are reflected in the following three levels: ① equipment damage, casualties; ② equipment or component life reduction; ③ transmitted or stored signals, data (analog or digital) are interfered or lost, and even electronic The equipment malfunctions and temporarily paralyzes or the entire system stops. For monitoring points, the possibility of being damaged by direct lightning strikes is very small. With the continuous development of modern electronic technology, the use and networking of a large number of sophisticated electronic equipment, the main culprits that destroy a large number of electronic equipment are induced lightning overvoltage, operating overvoltage and lightning wave intrusion overvoltage. Every year, various communication control systems or networks Cases of damage due to lightning strikes are not uncommon. Among them, the security monitoring system is damaged due to lightning strikes, and the events of automatic monitoring failure also often occur. Front-end cameras are designed for outdoor installation, and lightning protection systems must be designed and installed in areas with frequent thunderstorms.
