The composition of the installation of explosion-proof monitoring system:
For the security monitoring system, according to the different functions of the various parts of the system, we divide the entire security monitoring system into seven layers - presentation layer, control layer, processing layer, transport layer, execution layer, support layer, and acquisition layer. Of course, due to the increasing integration of devices, for some systems, some devices may exist in the system as multiple layers at the same time.
I. Presentation layer
Performance City is our most intuitive experience, it shows the quality of the entire installation of explosion-proof monitoring systems. Such as monitoring video wall, monitors, high pitch alarm horns, automatic alarm answering calls, etc. belong to this layer.
二. Support layer
As the name implies, the support layer is used to support the back-end equipment and protect and support the acquisition layer and the execution layer equipment. It includes brackets, protective covers and other auxiliary equipment.
Three. Acquisition layer
The acquisition layer is the key factor in the quality of the entire security monitoring system, and it is also the place where the system cost is the most expensive. It includes lenses, cameras, alarm sensors, and more.
Strong US analysis - coal mine explosion-proof monitoring equipment design and construction:
For coal mine explosion-proof monitoring and control design, in addition to the design specifications for explosion-proof monitoring and monitoring systems, reference can also be made to the explosive environmental electrical and application design standards developed by China in the explosion protection section, among which GB50198-94, GA/T70-94, and GB/T15411- 1994, GB/T13953-1992 deserves special attention. When designing coal mine anti-explosion safety monitoring, the design and installation construction content shall be decided according to factors such as the type and level of hazards released from the downhole and wells, the characteristics of the substances, and the environmental conditions.
The joints in the explosion-proof terminal equipment connection box must be lockable or screw terminal fixing method to avoid the line falling off, especially the power supply part resulting in spark explosion.
Explosion-proof camera terminal explosion-proof box like most of the door is fixed with screws, after the device is completed to adjust the time must be clockwise will counterclockwise, one by one to tighten the fixed screw to balance the pressure of the lid to avoid poor sealing and leakage Air explosion.
The system ground must use a point grounding method. Copper wires shall be used for grounding, and no closed circuit shall be formed. At the same time, it shall not be mixed with high-current power ground.
When the explosion-proof monitoring system adopts an independent grounding device, its grounding resistance must not exceed 4Ω (refer to the national regulations).
