Radio low-power transmission module applied to tms steam trap wireless detection system

Abstract

The invention discloses a radio low-power consumption transmission module applied to a TMS trap wireless detection system. The transmission module is characterized in that data transmission is performed by a LoRa technology, so that low power consumption can be kept; a communication distance is prolonged remarkably; and meanwhile, an ultrahigh building penetration capability is achieved. Moreover, the LoRa technology has the characteristics of large quantity of nodes, high capacity and low power consumption (an ordinary dry battery has a service life of over 10 years, and only dozens of [mu]A of current is consumed in a power saving mode), so that various problems encountered in leakage detection transmission of valves in plants can be solved perfectly by the LoRa technology.

Description

technical field

[0001] The invention relates to the technical field of wireless transmission, in particular to a radio low-power transmission module applied to a TMS trap wireless detection system. Background technique

[0002] The TMS steam trap wireless detection system is mainly deployed in factory workshops with irregular spatial distribution and long distances. It requires data collection and uploading to the cloud every 15 minutes (the default value can be adjusted by itself); There are also many testing equipment points, and it is difficult to maintain and update later.

[0003] Currently commonly used wireless transmission technologies are: Wi-Fi, Bluetooth, ZigBee, LoRa (Wireless Low Power Wide Area Network).

[0004] The full name of Wi-Fi is Wireless-Fidelity, which is a wireless extension technology of Ethernet. Usually the working frequency is around 2.4GHz and 5GHz. When a large number of child nodes are connected, the WiFi rate will decrease accordingly. At...
