Chemical plant Solution

Wireless local area network (WLAN) technology has gradually matured and put into commercial use since the 1990s. It can be used as an extension of wired network, and can also replace traditional wired network in some environments. Compared with traditional wired transmission solutions, WLAN network's realization has the advantages of simplicity, convenience, flexibility and low cost.

In recent years, there have been many cases of safety accidents in chemical plants, and the government has paid more and more attention to the production safety of chemical plants. In order to reduce the potential safety hazards in the production process, the use of wireless has become the first choice for major chemical plants to achieve network coverage.

Wireless Solution Architecture Project


Overall solution description:

The solution is deployed in the way of wireless controller AC+AP. This method can achieve zero configuration of AP, and all configurations are uniformly distributed to AP through the background AC, which simplifies operation, facilitates management and maintenance and former requirements of expansion. The wireless controller (AC) is deployed in the main equipment room of the factory, and the core switch is used as a DHCP server. The binding VLAN is responsible for allocating private network addresses to APs and STAs, and at the same time, business and management are isolated;

The wireless coverage adopts 2.4GHZ and 5.8GHZ dual-band signal coverage. There are three frequency points that do not interfere with each other in the 2.4G frequency band, called 1, 6, and 11. There are five frequency points that do not interfere with each other in the 5.8G frequency band, which are 149, 151, 153, 157, and 161. In the plan, the AP adopts non-interfering frequency point crossover to avoid interference between the same channels.

During commissioning, you can fine-tune the AP channel and signal transmission power according to the actual interference situation on site to reduce interference.
