On the one hand, it is necessary to ensure that the equipment can stably and efficiently access the network to achieve real-time data transmission; On the other hand, the convenience and safety of power supply should also be considered. The traditional network deployment method, which involves devices being powered separately and connected to the network, has problems such as complex wiring, high construction costs, and difficult maintenance in the later stages, making it difficult to meet the rapid development needs of smart parks. Therefore, it is urgent to find an efficient, convenient, and reliable network solution.
2、 Technical advantages of PoE switches
PoE (Power over Ethernet) switches, also known as Ethernet powered switches, are capable of transmitting data and power to network devices simultaneously through Ethernet cables. The emergence of this technology has completely changed the power supply mode of traditional network devices. The main advantages of PoE switches are reflected in the following aspects:
Simplify wiring and reduce costs: PoE switches do not require separate power lines for each device, only one Ethernet cable is needed to complete data transmission and power supply, greatly reducing the complexity of wiring and construction costs. For scenarios like smart parks with numerous and widely distributed devices, PoE switches can significantly reduce initial construction costs.
Easy to install and maintain: Due to simplified wiring, equipment installation has become more convenient and the construction period has been significantly shortened. At the same time, PoE switches support remote management and monitoring, and operation and maintenance personnel can configure, troubleshoot, and upgrade devices through the network, improving maintenance efficiency and reducing operation and maintenance costs.
Safe and reliable power supply: PoE switches adopt standard power supply protocols, which can automatically adjust the power supply according to the actual needs of the device, avoiding equipment damage caused by overvoltage, overcurrent and other issues. In addition, PoE switches also have functions such as short circuit protection and overload protection, ensuring the safety and stability of power supply.
Flexible expansion: With the development of smart parks, new devices may continue to increase. PoE switches support port expansion, and users can add device access at any time according to their actual needs, with strong flexibility and scalability.
