Explosion-proof industrial data transmission device based on multiple interfaces and data transmission method thereof

Abstract

The invention discloses an explosion-proof industrial data transmission device based on multiple interfaces. The explosion-proof industrial data transmission device comprises an explosion-proof tank body; a PCB is installed in the PCB installation cavity of the explosion-proof tank body, and a central processing unit MCU, a radio frequency module, an analog quantity input module, a network interface module, a dry node output module, a bus interface module and a power supply module are integrated on the PCB; the at least one communication antenna is arranged on the explosion-proof tank body and is connected with the PCB; and the plurality of wiring ports are arranged in the wiring port mounting cavity of the explosion-proof tank body at intervals and are respectively connected with the PCB. The invention further discloses a data transmission method of the explosion-proof industrial data transmission device based on the multiple interfaces. The device can be well compatible and butted with other industrial equipment, and can meet the harsh industrial environment in which explosive gas exists for a long time.

Description

technical field [0001] The invention relates to the technical field of industrial data transmission equipment, in particular to an explosion-proof industrial data transmission device based on multiple interfaces and a data transmission method thereof. Background technique [0002] At present, with the update and development of Internet technology, as well as the expansion of smart factories and smart manufacturing technologies, technologies and channels for information interaction are provided for the realization of the Internet of Everything. Today, industrial data transmission devices are widely used as bridges connecting node equipment such as industrial control, intelligent manufacturing, intelligent agriculture, and environmental monitoring. [0003] However, existing industrial data transmission devices have the following defects: [0004] 1. Most of the existing industrial data transmission devices only have one of RS485 interface, LORA radio frequency interface or a...

AI Technical Summary

Problems solved by technology

[0004] 1. Most of the existing industrial data transmission devices only have one of RS485 interface, LORA radio frequency interface or analog input interface, which cannot meet the various functional requirements of users in different scenarios

[0005] 2. Existing industrial data transmission devices do not have explosion-proof functions and cannot be applied to petrochemical pipeline sites

[0006] 3. Once the existing industrial data transmission device is delivered to the user, new functions and applications cannot be updated and iterated through remote loading, which undoubtedly greatly reduces the flexibility and periodicity of product use
