Explosion-proof control device for internet of things based on M2M

Abstract

The invention discloses an explosion-proof control device for the internet of things based on an M2M. The device is formed by three parts of a mother board, an intrinsic safe plate, and an M2M module. The mother board is formed by a MSP430 main chip circuit, six paths of analog acquisition circuits, four paths of digital quantity acquisition circuits, a watchdog circuit, an intelligent antitheft alarm circuit, etc. The intrinsic safe plate comprises a case processing circuit processing case signals of each circuit. The M2M module is formed by a MSP430 main chip circuit, a GSM communication module, a watchdog circuit, an RS485 communication circuit, a 24LC256 storage circuit, a buzzer drive circuit, and a power management circuit. The device uses an explosion-proof housing, and is provided with an explosion-proof intrinsic safe plate, and the device can effectively eliminate all accidents caused by spark and electric arc generated by a hardware circuit.

Description

technical field [0001] The invention relates to an Internet of Things control device, in particular to an M2M-based explosion-proof Internet of Things control device, which is suitable for on-site collection and device control in many industries. Background technique [0002] In industries such as industrial measurement and control and medical equipment, data acquisition and monitoring technologies have been applied more and more, and their proportion will continue to increase in future development. With the expansion of the industrial chain, the market has put forward higher requirements for real-time data collection and equipment power consumption: that is, on the basis of meeting the design principles of micro-power consumption and intelligence, it can collect field data in real time and remotely control equipment . [0003] At present, the remote control management technology level of many instruments and meters based on the Internet of Things on the market is still rel...

AI Technical Summary

Problems solved by technology

[0013] In terms of management, traditional data collection can only be done manually, and the operating status of the equipment cannot be monitored remotely. In addition, in areas containing explosive gas mixtures, the equipment will generate electric sparks and arcs during manual work, which will cause explosions

At the same time, the traditional technology cannot meet the technical needs of the market such as real-time collection of on-site data, anti-theft of equipment itself, and emergency fault handling.
