The remnants of the 2009 China (Zhongshan) Southern Green Seedlings Expo have not disappeared, and the ancient town is planning to develop the aquaculture industry through the Southern Green Expo platform and the upgrading of the traditional lighting industry. Recently, Su Wenming, deputy secretary of the party committee and town mayor of Guzhen Town, said in an interview that reflecting on the impact of the financial crisis on lighting export enterprises, innovation and upgrading will be the future development direction of Guzhen lighting industry. This year, the town government will strengthen the protection of lighting patent brands and encourage and guide enterprises to make their own products.
Lachang Guzhen Lighting Industry Value Chain
"The most difficult economic year in 2009 has become a history. Because the lighting of our town is obviously affected by the European and American markets, the financial crisis has dealt a great deal on the export of lighting. This prompted the town party committee and the town government to summarize and reflect on the development of the lighting industry in Guzhen." Su Enming said In the past, Guzhen Lighting Industry only focused on finished lamps. In the future, the government will invest financial resources and energy in lighting accessories, production equipment, logistics and other industries to guide enterprises to lengthen the industrial value chain. For example, the lighting accessories exhibition being prepared is government-specific. Guiding strategy.
At present, Guzhen is applying for “Lighting Product Technology Innovation Incubation Baseâ€, and plans to cooperate with domestic universities and scientific research institutions in the development, testing and design of lighting products. Prepare to introduce well-known domestic lighting designers, so that Guzhen Lighting can lead the industry trend.
In the sales of lighting, Guzhen will continue to enhance the brand of China Lighting Fair, and the concept of innovation will be well-known; it will focus on shaping the lighting culture of Lighting Street, and it is planned to establish a star-market hypermarket in the lighting industry, and change the store form of several stores in the past. "Small to a spare screw, up to a few square meters of chandeliers, buyers and consumers can find in the future lighting stores. We hope to form such a professional market, improve the cohesiveness of the merchants." Su Enming said.
"The price of the new variety Tianji in 2007 was 50 yuan to 70 yuan a pound. Last year, it rose to 150 yuan a pound. It is estimated that the price will rise to 200 yuan a pound this year." Su Enming's example of the price of pheasant multiplied, indicating The future prospects of aquaculture, especially the money turtles, are both ornamental and edible. At the just-concluded Green Expo, the Koi Exhibition and the Famous Turtle Exhibition are known as the national industry event and the largest turtle exhibition in the country, which will cultivate the future Jin Li and Ming turtle market for the ancient town.
“By geographical location, the ancient town is in the upper reaches of the Xijiang section of the Xijiang River, and the water quality is quite good. For the development of the aquaculture industry, the most important thing is water resources.†Su Enming said that the ancient town has the inherent advantages of developing aquaculture. In the future, with the help of the Green Expo brand, aquaculture and display such as ornamental fish and turtles will be gradually introduced, so that the garden industry and the ornamental fish farming industry will complement each other. Su Enming revealed that Koi and the famous turtle are expected to bring the first industry of Wanggu Town. At present, relevant parties in Japan intend to establish a Sino-Japanese Koi Culture Base with the ancient town to further promote the Koi culture.
What is a wireless AC controller? What does it do?
Wireless AC controller is a kind of network device, such as the AC100/150 of Fengrunda, which can be used to centrally control and manage wireless aps. It is the core of a wireless network and is responsible for managing all wireless aps in the wireless network. AP management includes: delivering configuration, modifying related configuration parameters, RF intelligent management, and access security control.
Why use a wireless controller, and what exactly does it do?
In fact, the role of the wireless controller is to play a gateway function between the WLAN and the Internet (on the router), and the data from different access points are aggregated and accessed to the Internet. The role of an access point (AP) is to complete wireless access, and it can control user access through network flags.
The role of wireless controllers
1, Flexible networking mode and excellent scalability
The AP does not need to be directly connected to the AC, so that the AP can be deployed in any place that needs to be covered through the network, such as you deploy an AP in each employee's home, and then connect to the wireless controller inside the enterprise through the VPN, you can expand the wireless network of the enterprise to the family of each enterprise member.
2, intelligent RF management functions, automatic deployment and fault recovery
Through the dedicated RF management module, we can initially estimate the AP deployment according to the user's architectural design drawing, and can calculate the average bandwidth of the wireless terminal, the coverage between AP and AP in the actual debugging process.
3. Centralized network management
All the configuration of the wireless network can be completed by configuring the wireless controller. For example, enable, manage, and maintain all AP devices and mobile terminals, including all functions such as radio wave spectrum, wireless security, access authentication, mobile roaming, and access users.
4, powerful roaming function support
The wireless controller uses AP as the boundary combined with fast RF management system, which greatly reduces the connection time between wireless client and AP, and thus realizes the function of fast roaming.
5. Load balancing
AP and wireless controller systems can distribute wireless users or terminals to nearby aps within the coverage area of an AP, ensuring the number of each wireless terminal or the sum of AP bandwidth transmission or the upper limit of each wireless terminal bandwidth.
6, wireless terminal positioning, rapid fault location and intrusion detection
Wireless controllers can track and locate the location of wireless terminals, such as wirelessly connected computers, PDAs and Wi-Fi mobile phones.
7, powerful access and security policy control
At present, the wireless system supports authentication of 802.1, WEB authentication, MAC, SSID, VPN, etc., and supports various encryption modes such as WEP, WPA, WPA-PSK, WPA2, etc., and all configurations can be configured globally through the wireless controller.
8, Qos support
AP and wireless switching systems can limit the maximum bandwidth of a user's wireless connection within each user's privileges. For different IP services, the system can also define different QoS queues through the wireless switch module. For example, for wireless voice applications, SIP and RTP protocols can be set in the high queue, while common applications such as http and ftp can be set in the low queue.
The wireless controller AC is more advanced than the AP, plays the role of manager in the wireless network, and the wireless controller AC also acts as a client to complete a series of functions in the wired network (such as authentication, authentication, etc.). However, wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but as a supplement to the protocol in specific applications, and its price far exceeds that of ordinary access point (AP) devices.
In small-scale wireless networks that use only a few aps, it is not economical to use expensive wireless controller AC equipment. However, if the number of wireless aps is large, more than 20 can be used AC controller.
