Illumination single-lamp monitoring system based on WSN (Wireless Sensor Network) and monitoring method thereof

Abstract

The invention discloses an illumination single-lamp monitoring system based on a WSN (Wireless Sensor Network) and a monitoring method thereof. The system comprises a control center, a lamplight node controller and a single lamp controller, wherein the control center is connected with the lamplight node controller in a communication way; and the single lamp controller is connected with the lamplight node controller by the WSN and is arranged on a lamp stem. The method comprises the following steps that the single lamp controller transmits the information of a controlled single lamp to the lamplight node controller by the WSN; the lamplight node controller subsequently transmits the single lamp information to the control center; the control center sends the control instruction; the lamplight node controller receives the control instruction and transmits the control instruction to the single lamp controller; each single lamp controller can control the single lamp by controlling the connection and disconnection of a multi-path switch of the single lamp; and the single lamp controller returns the operation results to the control center by the lamplight node controller. In the invention, one lamplight node controller can control a plurality of single lamp controllers; each single lamp controller has multi-path outputs and can control a plurality of lamps; furthermore, the controlling is more flexible, the node effect is more obvious, and the environment adaptability is stronger.

Description

technical field [0001] The present invention relates to a lighting monitoring system and monitoring method, in particular to a WSN network-based lighting single-lamp monitoring system and monitoring method. Background technique [0002] The existing lighting monitoring system mainly includes a control center, a remote terminal unit (RTU) and a communication network. The control center provides a human-machine interface for managers to monitor and manage the operating status of the lighting line; the remote terminal unit (RTU) is set together with the lighting transformer or power distribution cabinet to collect the input and output lighting of the power distribution cabinet The voltage and current on the line, and control the action of the relay in the power distribution cabinet to realize the remote switch light operation; the communication network is used to realize the communication between the control center and the remote terminal unit. Currently, GPRS, CDMA, 3G and rad...

Problems solved by technology

[0003] The existing monitoring system has the following disadvantages: 1) The remote terminal unit (RTU) must be used in one-to-one pairing with the transformer or power distribution cabinet, so as to realize the collection of voltage and current on the input and output lighting lines of the power distribution cabinet, and control the distribution cabinet. The relay in the electric cabinet acts to realize remote switch light operation, but there are thousands of transformers or power distribution cabinets in the lighting management department of a big city, even if the number of lights under the jurisdiction of the power distribution cabinet is small, a remote terminal unit is required ( RTU), which is a huge waste; 2) The variable power ballast installed on a single lamp can only use the time control method, that is, the variable power will automatically start after a period of time after the line is powered on and the light is turned on, and it cannot be dynamically adjusted according to holidays or road section information Adjusting the variable power start-up time cannot meet the requirements of control diversity, and the energy-saving effect is not good; 3) At present, the single-lamp control basically adopts the power line carrier method. In the case of passing through the transformer, the power line carrier cannot work normally, and there is no way to promote it on a large scale
