Scheme Background

Substations require that equipment can operate continuously and stably under high loads, high temperatures, or harsh outdoor environments with complex and changeable conditions. In the increasing number of industrial wireless scenarios, it should be able to connect to industrial wireless WAPs (Access Points) and supply power to them, while also supporting the access of terminal devices, such as patrolling robots. At the same time, it is required to provide a rich set of network management functions, such as VLAN (Virtual Local Area Network), ERPS (Ethernet Ring Protection Switching), Spanning Tree Protocol, Access Control List (ACL), etc. Moreover, it should offer a wide range of remote management capabilities, such as WEB management, CLI (Command – Line Interface) serial port management, and Telnet management. Network administrators can monitor and configure devices without leaving their offices, greatly simplifying the management of network equipment.

System Requirements

  • Power Supply Function: Industrial PoE (Power over Ethernet) switches support PoE technology and can supply power to connected devices through Ethernet cables. It is possible to use a single Ethernet cable to simultaneously transmit data and power industrial wireless WAPs and terminal devices (such as patrolling robots), simplifying the need for power cabling.

  • Data Transmission: Industrial PoE switches provide multiple Ethernet ports, enabling connection to multiple industrial wireless WAPs and other terminal devices.

  • Anti – interference and Stability: Industrial PoE switches are designed for industrial environments and possess anti – interference and stability features.

  • Network Management and Security: Industrial PoE switches typically offer a wealth of network management functions, such as VLAN (Virtual Local Area Network), QoS (Quality of Service), and network monitoring.

  • Expandability and Reliability: Industrial PoE switches generally support expandability and reliability, and can operate continuously and stably under high loads, high temperatures, or harsh environments.

In conclusion, industrial PoE switches, while connecting to and powering industrial wireless WAPs, enable the access of terminal devices (such as patrolling robots), provide reliable data transmission, network management, and security, and adapt to the special requirements of industrial environments. This solution can improve the wireless network coverage in industrial sites and the stability of terminal devices, promoting the development of industrial automation and intelligence.

System Solutions

In order to use industrial PoE (Power over Ethernet) switches in power substations to support the wireless WAP (Wireless Access Point) applications of automatic patrol robots, we can adopt the following solutions:

Select a suitable industrial – grade PoE switch: The SH – GM480016T meets the requirements of the industrial environment and has characteristics such as high reliability, strong anti – interference ability, dust – proof and waterproof properties.

Deploy wireless access points: Reasonably plan the location and quantity of wireless access points according to the layout of the power substation and the areas that need to be covered.

Ensure power supply: Since the industrial PoE switch provides power supply, it is necessary to ensure that the power input of the switch is stable and reliable.

Network security and isolation: As power substations are critical infrastructure, network security is of utmost importance. Appropriate network isolation measures should be taken, including Virtual Local Area Network (VLAN) configuration, Access Control List (ACL), etc., to ensure that the wireless communication network of the robot is isolated from other network environments and prevent potential security threats.

Signal optimization and coverage testing: After deploying the wireless access points, conduct signal optimization and coverage testing to ensure that the robot can obtain a stable wireless connection in all areas of the substation. Professional wireless testing tools can be used to evaluate indicators such as signal strength, interference conditions, and data transmission rate.

Monitoring and troubleshooting: Establish a network monitoring system to monitor the status of the PoE switch and wireless access points in real time. Through the monitoring system, potential failures can be detected and eliminated in a timely manner to ensure the normal operation of the automatic patrol robot.

Data backup and recovery: For the data collected by the automatic patrol robot, it is recommended to implement a regular data backup and recovery strategy. Ensure the security and integrity of the data for subsequent data analysis and applications.
