Abstract

The invention relates to underground engineering Internet of Things equipment based on LORA. The equipment comprises a main control module, an LORA communication module, a peripheral auxiliary power supply module and a mother board, wherein the main control module is in interactive connection with the LORA communication module through the mother board, the peripheral auxiliary power supply moduleis also connected with the main control module through the mother board, the equipment further comprises an equipment control module and an equipment state acquisition module, the equipment control module is composed of an interface unit, a forward and reverse rotation controller and an alternating current contactor, the input end of the interface unit is connected with the main control module through the mother board, and the forward and reverse rotation controller and the alternating current contactor are respectively connected with the output end of the interface unit. According to the invention, various alternating-current electric devices can be controlled, connection with a controlled device is convenient, no additional component is needed, connection with a power supply terminal ofa controlled device can be directly realized, wireless Internet of Things establishment can be realized without laying cables, and the equipment has the characteristics of large signal coverage range,strong wall penetrating capability, low power consumption and the like when used in underground engineering.

Description

technical field [0001] The invention relates to LORA wireless communication technology and control technology, in particular to a LORA-based underground engineering IoT device. Background technique [0002] At present, in the construction and deployment of underground engineering equipment control systems, the bus structure is usually used to connect the management layer, the monitoring layer, and the equipment layer in a wired connection. If additional equipment is required, the equipment layer needs to have spare input / output interfaces. , in the case that the system has been completed, adding equipment will bring a large amount of construction, including laying cables, adding control nodes, supplementing control cabinets, cable bridge construction, etc. There are many processes and a long construction period, which will affect the normal operation of the project. use, and has a certain impact on the reliable operation of the original system, and the system is not scalable...
