Linyi Yishui Central Hospital, also known as the Second People’s Hospital of Linyi City, was built in February 1945 when the war was raging. It used to be the East China Field Army Hospital and is the longest history of public welfare hospitals under the leadership of the Linyi City Government. In the 70 years since its establishment, with the care and support of the party and the local government and the people in the old Yimeng area, the hospital has developed into a tertiary A general hospital integrating medical care, first aid, scientific research, teaching, prevention, health care, and rehabilitation in the northern part of Linyi City. It is responsible for the medical and first aid tasks of counties in northern Linyi and neighboring cities and counties such as Rizhao, Weifang and Zibo. It serves a population of 8 million and has a service radius of 80 kilometers. It is a regional medical center in northern Linyi. It is a national baby-friendly hospital, a national medical qualification practice skill test base, a national chronic disease publicity base, and a designated hospital for the national breast survey project for one million women; it is also a standardized training base for young physicians in Shandong Province, Binzhou Medical College Clinical College, Weifang Medical College Graduate training base, Jining Medical College Teaching Hospital, Shandong Medical College Affiliated Hospital.
User needs
In terms of hospital informatization, the HIS system has been successfully built, and it also has a complete and high-speed switching network. This project aims to implement mobile nursing and mobile rounds systems in the hospital area, and with the help of the Internet of Things capabilities of the Internet of Things AP WN380R, to gradually achieve the goal of building the Internet of Medical Things on the basis of mobile nursing, so as to improve the treatment of medical staff to patients. Service efficiency and service quality.
In order to ensure the successful implementation of the mobile medical system, the wireless network has the following requirements: the entire hospital area needs to be wirelessly covered to ensure that all wireless terminals can roam seamlessly in the wireless area, with high-speed IEEE802.11 a/b/ g/n Wi-Fi standard and ISO/IEC 18000 RFID standard wireless access points are used as the access end of the wireless network; 10 Gigabit wireless controllers are used for unified management of more than 180 APs in the whole hospital; distributed PoE The switch supplies power to all wireless APs. Through the realization of the above requirements, Yishui Central Hospital can reliably and economically realize the deployment of wireless networks on the basis of the original line network, and provide a reliable and unified network infrastructure for intelligent wireless medical solutions. Combined with the actual situation of the customer, we adopted the wireless controller AC + POE + FAT/FIT AP architecture. Centralized control and unified management of wireless APs are adopted to realize local data forwarding to reduce the pressure and load of the wireless controller. The wireless network system has good scalability, can realize the self-healing function and load balance of the network system, and optimize the overall performance of the network.
Technical solutions
The wireless network construction project needs to achieve wireless coverage in areas A, B, C, Huakang Building, etc., and a total of about 160 dual-band IoT wireless APs WNDAP380R are deployed. The wireless AP uses the S3300-28G-POE+ POE 802.3 af power supply switch for unified centralized network cable power supply. The NETGEAR third-generation intelligent wireless controller WC9500 is connected to the core switch through a gigabit link to achieve unified management of wireless APs and high-speed local forwarding of data streams. Reserve two wireless APs as a backup after the association is completed.
The wireless AP uses NETGEAR dual-band IoT AP WNDAP380. WNDAP380R itself is a standard high-performance 802.11N Wi-Fi wireless thin AP, which can work with AC; this mode can provide both 2.4GHz and 5GHz 802.11N 300Mbps Wi-Fi wireless signal and RFID radio frequency signal coverage. WNDAP380R has designed an application expansion slot that can support third-party RFID reader modules. When the RFID reader module is inserted, WNDAP380R can directly convert the instructions of the RFID reader into a standard Ethernet data format through middleware technology, and complete the collection and command control of the electronic label information by the application. WNDAP380R cooperates with the intelligent wireless controller When in use, it can automatically optimize and adjust the RF channel, and the configuration and firmware can be distributed in a centralized manner, with diverse and flexible user security and management strategies. Unified management and status monitoring of RFID readers and tags.
In terms of speed, compared with 802.11a and 802.11g networks, it can provide up to 15 times the transmission rate and 10 times the coverage, stylish and elegant appearance design, convenient and diverse installation methods (such as: ceiling, wall, desktop), It can work in both 2.4GHz and 5GHz wireless frequency bands to achieve maximum wireless throughput. It is compatible with 802.11a, 802.11g and 802.11b network devices. It integrates 802.3af PoE power over Ethernet function to facilitate network deployment and reduce costs. Support WC9500 management, can achieve centralized management in large-scale network deployment, wireless coverage can be deployed in a large area through the wireless distribution system (point-to-point and point-to-multipoint bridging), security features include WPA, WPA2, illegal AP detection and 802.1x with Radius support, with wall mounting kit, easy to install on the wall or ceiling, the built-in optimized antenna can provide the best radio frequency performance, you can choose an external antenna, support 2.4GHz antenna accessories.
The wireless controller uses the WC9500 third-generation intelligent wireless controller to facilitate the management and configuration of wireless APs throughout the network. The wireless controller provides seamless roaming, user secure access, WIDS, automatic policy control based on user roles, and dynamic wireless channel control , Radio frequency power automatic adjustment, wireless user automatic load sharing and other functions. Three wireless controllers stack up to support centralized management of up to 1500 APs, ensuring that the wireless network will fully cover the access of a large number of APs in the future.
Effect
At present, the entire network has been officially operated, the wireless signal coverage is intact, and the user’s wireless medical application has been put into operation with good results. In this project, NETGEAR’s medical Internet of Things infrastructure solution has played a very good supportive role in the entire medical system, and has successfully assisted Yishui Central Hospital in taking an important step in the construction of medical information, which has been greatly affirmed by users .
