Project Introduction
For most people, a warehouse is usually just a place to store something. Today, the supply chain business, the role of the warehouse has undergone great changes, and become a crucial competitive advantage. Therefore, how to use advanced communication technology and automation solutions to reduce human input and improve inventory accuracy as the key to comprehensively enhance the storage capacity. A leading dairy company with annual production capacity of more than 7 million tons has established automated production and intelligent warehousing systems in dozens of manufacturing plants throughout the country to meet stringent quality control processes and large-scale production needs. Among them, the stability of wireless communication equipment will be the impact of automated production and intelligent warehouse one of the key aspects of the normal operation. Advantech Wireless AP / CPE, wireless serial port service equipment not only solve the existing needs of the problem, but also provides more than the user expected high reliability wireless communication system.


system requirement
Through the integration of monitoring equipment, computers, programmable automation controller, wireless network equipment and independent research and development of software, automated warehouse system integrators to help dairy enterprises to establish automated warehouse storage wireless communication system. Operation and control of the system Operation by the control center, the control center operator sends instructions to the stacker and the shuttle to automatically store or select the material on the specified shelf.
The normal operation of the system depends largely on the stability of the network. Due to the large storage capacity, high density and narrow aisle, the equipment can provide wireless network connection capable of resisting interference and stable communication. While providing better wireless signal coverage and reception capability is the most basic and effective way to combat interference and shielding caused by dense inventory and metal viaducts. When the stacker is running, the roaming communication between different APs is realized by the specific algorithm.
System specification
Advantech's EKI-6311GN is an excellent wireless AP / CPE product that complies with the IEEE 802.11 b / g / n wireless communication standard and is well suited to meet the needs of smart wireless communications warehousing. To solve the problem of weak signal, we will install the equipment at both ends of the shelves, the use of leaky cable to provide wireless coverage and antenna bridging; In addition, the stacker EKI-6311GN can be used as client mode (CPE). As the EKI-6311GN can easily achieve the entire warehouse wireless network coverage, and can also be used as a bridge to connect wired equipment to the plant center network, the central control room can be seamlessly connected to the warehouse equipment, and stacking machine installed EKI-6311GN also Automatically detects and connects to the best AP based on signal strength to ensure reliable communication. If the PLC communication interface for the serial port through the EKI-1351 to achieve rapid roaming communication.
In addition, the EKI-6311GN has an output power of up to 26 dBm (400 mW) and can flexibly adjust the transmit frequency of its RF module to provide a flexible and stable communication signal. At the same time, Advantech proprietary firmware (Firmware) for the harsh site environment specifically related to optimize the transmission quality is more ideal. In addition, the wireless distribution system (WDS) protocol extension can flexibly expand the user network range, without the use of cable to connect the access point, while supporting spanning tree (RSTP) protocol and IGMP protocol, its low voltage PoE power supply (12VDC) and IP55 Protection certification, so that the EKI-6311GN become the ideal choice for many industrial applications ideal wireless devices.

to sum up
In today's highly competitive industrial applications, inefficient material storage and retrieval will cause the harvest period is too long, the warehouse operator's work efficiency and many other issues. And through Advantech wireless communications related equipment to build automated production systems and intelligent storage system of reliable wireless communication network for users to create a strong communication security, so that the user's system implementation arbitrary. Through the actual test shows that, compared with many other friends of similar products, in the same working environment, Advantech wireless communications products can provide more stable communication quality. Based on excellent product quality and many practical application case verification, so that Advantech has become the best brand trusted customers.
