A low-power monitoring data wireless acquisition system and method

Abstract

The invention discloses a wireless collection system for low-power monitoring data, which includes an on-site mechanism, a remote communication module and a cloud; the on-site mechanism includes a relay control module, a first wireless communication module, and multiple sampling modules; the sampling module includes multiple The sensor and the bottom control module; the sensors are electrically connected to the bottom control module; the bottom control module is respectively connected to the relay control module through the first wireless communication module, and the relay control module is connected to the cloud through the remote communication module. In the wireless collection method for low-power monitoring data, the sampling module and the wireless transmission module enter a sleep mode. The relay control module wakes up the sampling module and the wireless transmission module under the wake-up reservation condition; the sampling module and the wireless transmission module enter the working mode; the sampling module collects the monitoring data and transmits them to the relay control module through the wireless transmission module to avoid damage to the communication line , and reduce the power consumption of field mechanism and data transmission module.

Description

technical field [0001] The invention relates to the technical field of monitoring data collection, in particular to a low-power consumption monitoring data wireless collection system and method. Background technique [0002] At present, the monitoring equipment usually includes an on-site mechanism and a relay control module. The on-site mechanism includes one or more sensors and the underlying control module, and the underlying control module corresponds to a relay control module; between the on-site mechanism and the relay control module 485 and other wired communication methods are mostly used for data transmission, and the communication distance is inversely proportional to the communication speed. Since 485 communication is wired communication, it will be difficult to install monitoring equipment in special terrain, such as wiring across a river, or wiring across a river. And the cost of wiring in places with steep terrain will be very high. Secondly, after the wiring i...

[0002] At present, the monitoring equipment usually includes an on-site mechanism and a relay control module. The on-site mechanism includes one or more sensors and the underlying control module, and the underlying control module corresponds to a relay control module; between the on-site mechanism and the relay control module 485 and other wired communication methods are mostly used for data transmission, and the communication distance is inversely proportional to the communication speed. Since 485 communication is wired communication, it will be difficult to install monitoring equipment in special terrain, such as wiring across rivers, or wiring across Moreover, the cost of wiring in places with steep terrain will be very high. Secondly, after the wiring is completed, the communication line may be disturbed or damaged by wild animals, geological corrosion, collapse and other natural conditions.

As a result, the cost and maintenance cost of using 485 communication will be very high. In addition, since most of the areas that need to be monitored may have hidden dangers of natural disasters, wiring construction in the monitoring area may induce disasters to occur in advance

Due to the complex situation on site, it is very inconvenient to replace the power supply in time, and there are extremely high requirements for the low power consumption of the slave and the data transmission module
