Description

Technical Field

[0001] The utility model relates to the technical field of network communications, in particular to a local upgrading system for an engineering site network. Background Art

[0002] With business development and the increasing informatization of business operations, software upgrades and the addition of new functional modules are inevitable. Engineering projects often require addressing various custom requirements, often requiring on-site software upgrades for engineering equipment. However, network instability on-site often results in slow downloads of upgrade packages and data updates. The upgrade process can even be interrupted, resulting in software corruption or equipment malfunction. During on-site software upgrades, the lack of a good network environment often creates significant challenges for on-site operations. One current solution involves storing the required offline upgrade package on an offline terminal. At the project site, the engineering equipment with the software to be upgraded is locally connected to the offline terminal via a signal data cable. The offline upgrade package is then transferred to the engineering equipment, and the software is then locally upgraded on the equipment. This approach avoids network issues associated with on-site data downloads. However, many engineering equipment lacks standardized signal data cable interfaces. A lack of a corresponding signal data cable on-site can hinder software upgrades, negatively impacting project progress and efficiency. Utility Model Content

[0018] The present invention is further described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 As shown, the local upgrade system of the engineering site network of this embodiment includes engineering equipment with software to be upgraded and an external setting interface connected to the engineering equipment through a plug-in connection. The engineering equipment includes a control module (such as an MCU chip) and an OTA upgrade interface, a local upgrade module, a local area network routing interface and a WiFi device that are respectively connected to the control module for communication. The local area network routing interface and the WiFi device together constitute the network interface of the local upgrade system of the engineering site network. The control module is as shown in FIG. Figure 2 As shown, the LAN data communication is realized by connecting the LAN routing interface via the RS485 interface or accessing the WiFi communication LAN broadcast by the WiFi device. Figure 3As shown, the external setting interface is specifically a double-headed USB plug-in adapter with a built-in USB conversion chip U1. The USB conversion chip U1 includes a USB interface D for communicating with an offline terminal and a USART1 pin for communicating with a control module. The offline terminal is a hardware device with a USB reading function that stores a software upgrade package (such as a USB flash drive). The USB conversion chip U1 of the double-headed USB plug-in adapter is pre-recorded with USART1 pin configuration information, which is used to trigger interaction with the control module according to the status of the USB interface D connected to the offline terminal.

[0020] The software upgrade process of the local upgrade system of the engineering site network of this embodiment is as follows: a double-headed USB plug-in adapter with an offline terminal is connected to the USB interface of the engineering equipment through plug-in as an external setting interface, and the USB conversion chip U1 of the double-headed USB plug-in adapter performs level conversion to trigger the control module of the engineering equipment to interact with the offline terminal for instructions and data, thereby realizing the transmission of the upgrade control instruction of the offline terminal to the control module, and the control module calls the OTA upgrade interface according to the received upgrade control instruction, thereby sending the upgrade information corresponding to the upgrade control instruction to the local upgrade module to be upgraded through the OTA upgrade interface, and the local upgrade module performs the upgrade operation according to the received upgrade information and then feeds back the upgrade result to the OTA upgrade interface, and the OTA upgrade interface transmits the received upgrade result back to the control module.

[0021] The OTA upgrade interface and the local upgrade module communicate over the local area network (LAN) via the aforementioned network interface. The control module accesses the local OTA upgrade interface via a terminal page, such as the engineering equipment backend control interface or the external browser settings page. The OTA upgrade interface of this embodiment is connected to the LAN via a wireless connection. The wireless connection path may include one or more of Bluetooth LE, Lora, Zigbee, Zwave, and Sub-1G, depending on the engineering equipment. The wireless connection between the OTA upgrade interface and the LAN utilizes dual encryption at both the network and application layers, enabling encrypted processing of engineering information.

[0022] The local upgrade system of the engineering site network of this embodiment establishes LAN data communication between the OTA upgrade interface and the local upgrade module through the network interface, and then connects to the local external setting interface through the control module to obtain upgrade control instructions, thereby building a local OTA upgrade service environment. The OTA upgrade interface obtains upgrade control instructions and corresponding upgrade information from the offline terminal through the local LAN, so there is no need to use the OTA upgrade interface to connect the engineering equipment as an edge device to the cloud processor for remote communication for upgrading, nor is there any need to perform software upgrades on the engineering equipment through a dedicated signal data line interface on the engineering equipment. The entire upgrade process only requires offline terminal access operations on the external setting interface to realize the upgrade of the local upgrade module at the engineering site, thereby completing the local software upgrade operation of the equipment in an engineering environment with poor network, avoiding the upgrade failure caused by network abnormalities and adversely affecting the project progress and efficiency.

[0023] The external setting interface of this embodiment can be changed to an offline terminal with the function of a USB conversion chip U1.

[0024] When the local upgrade system of this embodiment is in working state, the power interface of the engineering equipment supplies power to the external setting interface and the WiFi device.

[0025] The local upgrade system for the engineering site network of this embodiment is based on the layout of Wi-Fi devices and gateway devices / sub-devices, supporting Ethernet, Wi-Fi, Bluetooth, 485, and other types of devices. It can batch-set SSIDs and passwords for Wi-Fi devices through local communication methods such as Bluetooth and 485, eliminating the tedious process of configuring Wi-Fi devices one by one. The hardware can discover gateway devices within the local area network, batch-upgrade gateways and gateway sub-devices, automatically match and upgrade devices based on uploaded firmware, and has complete upgrade logging capabilities. In addition, it can use local network functions to update other data besides software, such as MP3 files in local playback devices.

[0026] In the local upgrade system of the engineering site network of this embodiment, the network interface is also used to connect the local area network connected to the OTA upgrade interface to the Internet or an external wide area network. The ways of connecting the local area network to the Internet or an external wide area network include NBIOT, WiFi, 2 / 3 / 4G networks, etc., to realize online software upgrade operations under good network conditions.

[0027] The above is only an embodiment of the invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention and still fall within the scope of patent protection.
