[0022] Embodiment 1: As Figures 1-7 shown, the present invention provides a technical solution: a data acquisition and transmission conversion gateway, including a conversion gateway 1. An anti-collision mechanism 2 is provided on the outer side of the conversion gateway 1, and heat dissipation modules 3 are provided on the inner side and both ends of the conversion gateway 1. The conversion gateway 1 includes an outer housing 101. A main board 110 is provided inside the outer housing 101. A processor 112 and a StarFlash module 113 are provided at the bottom of the main board 110, and the StarFlash module 113 is provided on the side of the processor 112; The anti-collision mechanism 2 includes an anti-collision top plate 201 and an arc-shaped plate 203. The anti-collision top plate 201 is provided above the outer housing 101, and the arc-shaped plate 203 is provided at the four corners of the outer housing 101. Springs 202 are connected to the four corners at the bottom of the anti-collision top plate 201, and the bottom ends of the springs 202 are all connected to the top of the outer housing 101. Elastic pieces 204 are connected to both ends of the inner side of the arc-shaped plate 203, and the elastic pieces 204 are symmetrically installed at the four corners outside the outer housing 101.

[0023] In this embodiment, the outer housing 101 is arranged outside, which facilitates providing an installation space for the main board 110 and plays a protective role. The processor 112 and the SparkLink module 113 are distributed on the main board 110 and are electrically connected, thereby facilitating information processing. At the same time, the SparkLink module 113 has the SparkLink function. The terminal consists of an ARM32-bit chip Linux operating system + a SparkLink chip. The communication ports are composed of an Ethernet port, RS232, and RS485. The system has more than 200 built-in industrial protocols. Data of PLCs, numerical control devices, instruments, etc. are collected through the Ethernet port, RS232, and RS485, and the data is processed at the edge end. Then, the data is transmitted to the SparkLink router through the SparkLink chip. It consists of an ARM32-bit chip Linux operating system + multiple SparkLink chips, and can realize networking of less than 40 terminals. Through the data time-sharing reception and distribution algorithm, reliable and real-time reception and processing of data are achieved. It mainly solves the stability problem and transmission rate problem of wireless technologies such as WiFi, LoRa, ZigBee, and Bluetooth in industrial scenarios, and greatly solves the problem of unreliable wireless transmission in industrial scenarios. The anti-collision top plate 201 is arranged at the top of the outer housing 101 in cooperation with the spring member 202. Through the external protection of the anti-collision top plate 201 and the buffering of the spring member 202, it is beneficial to reduce the impact force when the top is impacted and provide protection for the internal precision components. The arc-shaped plate 203 is installed and connected by the elastic piece 204, which is beneficial to provide protection at the four corners, further improving the protection performance, ensuring the stable use of the device, and effectively extending the service life.

[0024] The system consists of a SparkLink gateway at the edge side, a SparkLink router at the network transmission side, and an Internet of Things platform at the platform side. In a wireless scenario, the SparkLink gateway collects controller data from the device side through industrial protocols, processes the data through data calculation, and then transmits the data to the SparkLink chip in the SparkLink router through the SparkLink chip in the SparkLink gateway. Then, the data is processed in the SparkLink router and uploaded to the Internet of Things platform. The SparkLink processing method helps to ensure the security and stability of industrial data collection and data transmission. Among them, data collection is mainly achieved by the SparkLink gateway. 210 industrial protocols are built into the gateway, and a proprietary model of the controller / control system is constructed in the gateway according to the protocols. When the gateway is connected to the controller / control system of the industrial device, the model will automatically synchronize the data in the controller / control system of the industrial device. According to the changes in the data in the model, valuable data is identified through production knowledge and requirements. Then, the encryption algorithm in the encryption chip is called to encrypt the data. The data transmission part is mainly composed of the SparkLink gateway and the SparkLink router. To ensure the stability of data transmission, the active-active backup and weighted round-robin algorithms are adopted to ensure the stability of the connection between the gateway and the router and the load balancing during large data transmission. The data transmission is all encrypted data after passing through the encryption algorithm. This prevents the data from being decrypted after being eavesdropped on during the transmission process.

[0025] The data received by the gateway from the polling instruction of the router transmits the data corresponding to the instruction to the SparkLink router through the SparkLink chip. The SparkLink router does not store the data and directly forwards it to the server. The data is mainly stored in the gateway, where a data queue is created in the gateway or stored in SQLite. According to the load balancing management mechanism of the router, the data in the gateway is gradually released. The load balancing management mechanism is adaptively configured according to the amount of data and the number of connected gateways. Manual configuration can be performed in case of emergency.

The cooperation of the radiator 301 and the heat dissipation fins 302 facilitates the rapid export of internal heat, which is conducive to improving the heat dissipation efficiency.
