[0014] The following further describes the embodiments of the present invention with reference to the accompanying drawings, wherein:

[0015] Figure 1 FIG. 4 shows a network system applicable to multiple distributed inspection sites according to one embodiment. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] Figure 1 FIG. 1 shows a network system suitable for multiple dispersed inspection sites according to an embodiment. Only two inspection sites are schematically shown in the network system, but it is understood that the network system can be easily expanded to be used for more inspection sites.

[0018] The network system includes a line 1 for a first inspection site and a line 2 for a second inspection site. Line 1 for the first inspection site includes a wireless AP device 1 (AP1) deployed at the first inspection site, an access switch 1 deployed at the first inspection site, a test room computer 1 (test room PC1) deployed at the first inspection site, and an aggregation switch 1. Line 2 for the second inspection site includes a wireless AP device 2 (AP2) deployed at the second inspection site, an access switch 2 deployed at the second inspection site, a test room computer 2 (test room PC2) deployed at the second inspection site, and an aggregation switch 2. Aggregation switches 1 and 2 do not need to be deployed at the inspection sites.

[0019] In one embodiment, access switch 1 and access switch 2 are POE (Power over Ethernet) switches. Access switch 1 is used to provide network and power supply for wireless AP device 1 , and access switch 2 is used to provide network and power supply for wireless AP device 2 .

[0020] Inspection room computer 1 (inspection room PC1) is connected to access switch 1, and inspection room computer 2 (inspection room PC2) is connected to access switch 2. Access switch 1 is connected to aggregation switch 1, and access switch 2 is connected to aggregation switch 2.

[0021] The network system also includes a core switch connected to aggregation switch 1 and aggregation switch 2, respectively; an access controller (AC) directly connected to the core switch for centrally managing wireless AP devices 1 and 2; and a logistics system server connected to the core switch. The AC is configured as an AP gateway and is connected to the core switch.

[0022] In one embodiment, a firewall is provided between the core switch and the logistics system server. In one embodiment, the AP has excellent outdoor coverage performance and super strong IP68 waterproof, dustproof and lightning protection capabilities, and is suitable for high-density coverage scenarios with multiple users.

[0023] In one embodiment, the wireless AP device is wall-mounted for ease of installation, maintenance, and replacement.

[0024] In one embodiment, the network system further includes a wireless signal booster provided at each inspection site.

[0025] exist Figure 1 In the example, Line 1 and Line 2 each have an aggregation switch. However, two or more lines can also share a single aggregation switch. Therefore, in one embodiment, the network system includes one or more aggregation switches, wherein the POE switch at each inspection site is connected to one of the one or more aggregation switches, and the core switch is connected to the one or more aggregation switches.

[0026] The above network system schematically illustrates only two inspection stations. However, it is understood that a network system involving more inspection stations may further include, for example, Line 3 for the third inspection station, Line 4 for the fourth inspection station, Line 5 for the fifth inspection station, and so on. Each of Line 3, Line 4, and Line 5 may include similar equipment to Line 1 and Line 2 and be networked in a similar manner.

[0027] With the network system of this application, regardless of the number of access switches or the distance between APs, after configuring the switches to achieve network interoperability, each AP goes online and forms a network, which is centrally controlled by the access controller (AC) to achieve network roaming. The network system of this application ensures secure data transmission through centralized network management, can monitor online users in real time, avoids the situation where traditional routers are unable to monitor malicious users, and improves the security of the entire network service process. During daily use, it can achieve centralized management of each AP terminal and refined user management, and can promptly detect and resolve problems during use.

[0028] During operation, the AC is configured as an AP gateway and acts as a DHCP server to assign IP addresses to APs and terminals. The service data is forwarded in tunnel forwarding. Through the company's existing lines, without adding a separate line, the AC is directly connected to the core switch, and both ends are configured in TRUNK mode. The DHCP main switch is turned on on the AC, and management and service VLAN 2024 are created. The interface transparently transmits management and service VLAN 2024. The DHCP server function in the interface address pool mode is enabled on the interface connecting the AC and the core switch. The interconnected AC address is excluded from the DHCP address pool, and the DNS server address used by users when accessing the Internet is configured. In line 1, the core switch is connected to the aggregation switch 1, and the direct connection interface is configured in TRUNK mode. The interface transparently transmits the original service VLAN segment and adds a new transparent VLAN 2024. The aggregation switch 1 is connected to the access switch 1, and the direct connection interface is configured in TRUNK mode. The interface transparently transmits the original service VLAN segment and adds a new transparent VLAN 2024. The access switch is set at each inspection site and belongs to the network end of this embodiment. Access switch 1 is connected to AP1, and the interface link type is configured as trunk mode. The planned management VLAN and service VLAN are configured on the switch interface. In this embodiment, the management VLAN and service VLAN are merged into VLAN 2024 for ease of management. VLAN 2024 is configured for transparent transmission during access communication. AP1 uses the default authentication mode. The AC management page shows that AP1 is connected to the network and is automatically online. Wireless services are configured on the AC, a new SSID broadcast is created, and the security authentication mode is set to key authentication to ensure wireless access network security. Similarly, the same configuration can be performed for line 2.

[0029] In one embodiment, one manageable POE switch and one wireless AP are deployed at each inspection site. The switch and AP are configured to achieve network connectivity with upstream network devices, and an AC controller is connected alongside the core switch in the computer room. The AP is connected in FIT mode, and the POE switch acts as an access layer switch to provide network and power to the AP. A common service VLAN and an AP-specific VLAN are configured on the POE switch, and the uplink interface is configured in TRUNK mode to allow access to the service VLAN and AP-specific VLAN, ensuring that normal services are not affected. An AC controller is connected alongside the core switch in the computer room, and the AC is configured as a DHCP server to assign IP addresses to the APs. The AP-specific VLAN is configured to complete AP online access on the AC. The AP's SSID is configured on the AC management page, wireless network security key authentication is deployed, and network roaming is implemented for all distributed nodes.

[0030] This utility model adopts a wireless network coverage transmission method based on a decentralized environment. When the company's external network is interrupted or the network is disconnected due to security measures, and the Internet cannot access the internal network, the deployed wireless AP network covers the weighing site, allowing drivers to access the WIFI to connect to the internal network and log in to the intelligent logistics system to complete the weighing business. To ensure network security, a wireless network controller AC device is installed in the computer room, which can monitor the network connection status of drivers at each weighing site in real time, ensuring the security of network access and the continuity of sales business in the event of abnormal Internet disconnection.
