Through the above description, we have briefly understood the role and characteristics of some wireless controllers. This article will explain the role of the wireless controller in detail, so that you can get a deeper understanding of the wireless controller. The role of the wireless controller is to function as a gateway between the WLAN and the Internet (on the router) to aggregate data from different access points and access the Internet. The role of the access point (AP) is to complete wireless access, which can control user access through network flags. The role of the wireless controller The wireless controller AC is more advanced than the AP and acts as a manager in the wireless network. The wireless controller AC also acts as a client to perform a series of functions (such as authentication, authentication, etc.) in the wired network. However, the wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but is a supplement to the protocol in a specific application, and its price far exceeds that of an ordinary access point (AP) device. Therefore, in a small-scale wireless network using only a small number of APs, it is uneconomical to use an expensive wireless controller AC device. The industrial-grade wireless controller terminal can directly replace the traditional wired transmitter to realize wireless analog quantity acquisition and transmission, and solves the problem that the wired scheme is complicated to construct and the equipment maintenance cost is high. Used in conjunction with sensors, transmitters, PLCs, DCS, inverters, smart meters, etc., successful applications have been: Wireless oil drilling rig well rope tension wireless transmission equipment; Pump room frequency converter wireless speed control; Wireless boiler room equipment monitoring, steel plant monitoring equipment, grouting equipment wireless control remote control; Wireless power transformer oil temperature wireless monitoring; Wireless rubber factory vulcanization production process wireless monitoring system. Summary: The above is the introduction of the role and application of the wireless controller, I believe that through this article you have really understood the role of the wireless controller.

Aluminum tube is a kind of non-ferrous metal tube, refers to the use of pure aluminum or aluminum alloy by extrusion processing along its longitudinal full length hollow metal tubular material. Aluminum profile specifications can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy brand aluminum profiles.
Aluminum pipe is mainly divided into the following types: 1. According to the shape of the pipe: square pipe, round pipe, pattern pipe, special shape pipe, global aluminum pipe. 2. According to the extrusion method, it can be divided into seamless aluminum pipe and ordinary extrusion pipe. 3. According to the precision: ordinary aluminum tube and precision aluminum tube, the precision aluminum tube generally needs to be reprocessed after extrusion, such as cold drawing, rolling. 4. Divided by thickness: ordinary aluminum tube and thin-walled aluminum tube. 5. Performance: corrosion resistance, weather resistance, wear resistance, light weight. 6. Characteristics: It is a kind of high strength duralumin, which can be strengthened by heat treatment. The plasticity is medium in annealing, hardening and hot state, and the spot welding is good. The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed. Corrosion resistance is not high, often using anodic oxidation treatment and paint method or surface coated with aluminum layer to improve the corrosion resistance. It can also be used as a mold material.
Aluminum tube is widely used in all walks of life, such as: automobile, ship, aerospace, aviation, electrical appliances, agriculture, mechanical and electrical, home and so on.
