Abstract

The present invention relates to a data acquisition and transmission system based on LORA, comprising a main control MCU module and a power supply circuit connected thereto, an analog quantity acquisition unit, and a digital quantity acquisition unit; also including a LORA module, a LORA gateway and a monitoring center, and a main control MCU module Communicating with the LORA module through SPI, the LORA module is used to convert the data into LORA data, and then sends the LORA data to the LORA gateway; the LORA gateway is used to receive the LORA data, and The LORA data is converted into flow data and sent to the monitoring center. The beneficial effects of the present invention are as follows: 1. The power supply and data acquisition in the system are all isolated, which realizes the electrical isolation between the measured signal and the system, enhances the anti-interference ability, and can be used in complex field environments and can be used reliably. 2. The system applies LORA communication technology to underground coal mines, and can transmit on-site data to the monitoring center more conveniently and quickly through wireless communication.

Description

technical field [0001] The invention belongs to the field of computer data acquisition, in particular to a data acquisition and transmission system based on LORA. Background technique [0002] At present, the acquisition and transmission of on-site data in coal mines mainly rely on wired transmission. In a complex environment, a large number of cables need to be arranged, and interference between signals is likely to occur. Moreover, due to the complex application environment of explosion-proof products, there are higher requirements for the stable operation of the equipment. The data acquisition module is not isolated, and there is no electrical connection between the acquisition unit and the main circuit. A unit failure will destroy other units of the equipment. Poor reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a data collection and transmission system based on LORA. The system applies LORA com...
