Embodiment 1

[0035] In this embodiment, a closed environment of 40 square meters is selected as the monitoring site, and 15 monitoring nodes are evenly set at the monitoring site, and each monitoring node is provided with a temperature sensor 001 and a humidity sensor 002. Taking the temperature sensor as an example, at the current time T, The temperature detected by the temperature sensor in monitoring node A is 20°C. At the last time T-1, the temperature detected by the temperature sensor in monitoring node A is 11°C. The temperature error at these two moments is 9°C. The first error threshold is 5°C, and the temperature error at this time is greater than the first error threshold, the monitoring node A performs fault self-inspection, generates a fault file F=A{001, T, 20°C}, sends the fault file to the control platform, and controls If the platform does not find the fault file with the sensor type 001 within the time period [T-5, T+5], then there is a fault in the monitoring node A, and ...

Abstract

The invention discloses a self fault-checking method for environment monitoring nodes. The detection data of the current moment are compared with those of the last moment. When the error of the data is great, a node conducts self fault-checking to effectively prevent node fault, uploading of error data and influence on environment monitoring. When the node detects fault, a control platform analyzes fault of other nodes to determine the type of the fault so as to accurately solve the fault.

Description

technical field [0001] The invention belongs to the field of node fault detection, in particular to a self-diagnosis method for environmental monitoring node faults. Background technique [0002] In order to effectively monitor the environment and achieve the required physical environment indoors, various means are often used to achieve it. The most common way is to deploy a monitoring node composed of several sensors in the monitoring environment, detect environmental data through the sensors in the monitoring node, and send the detected environmental data to the control platform, and monitor whether the indoor environment meets the requirements through the control platform. [0003] Application number: 201510702970.0, providing a personalized indoor environment monitoring system and indoor environment monitoring device technical field. The monitoring system includes several wireless sensor groups, several routers, a network coordinator, a control terminal and a feedback c...
