Problems solved by technology

Due to the different distances between each single lamp controller 2 and the lighting branch controller 1, as well as the influence of trees and buildings in the actual environment, the communication between the lighting branch controller 1 and individual single lamp controllers 2 will be successful. The rate is low, which affects the acceptance of the single control commands sent by these single lamp controllers 2
Based on the current defects of star networking, it is necessary to use high-power communication modules to improve communication reliability in practice. Due to the high cost of high-power modules, the overall cost of the system has increased significantly, and the communication effect is difficult to guarantee.

Embodiment 1

[0047] like figure 2 As shown, the WSN network is an implementation of a tree network, and the control system of this embodiment consists of a lighting branch controller 1 and six single-lamp controllers 2 . For the convenience of description, the six single lamp controllers 2 are respectively named as: LeafNode1, LeafNode2, LeafNode3, LeafNode4, LeafNode5 and LeafNode6, the same below.

[0048] The lighting branch controller 1 is connected to LeafNode1 and LeafNode2 respectively. LeafNode3 and LeafNode4 are respectively connected to LeafNode1, and LeafNode5 and LeafNode6 are respectively connected to LeafNode2. LeafNode1 and LeafNode2 are the first-level single lamp controllers. It is the secondary single lamp controller.

[0049] To realize the group control command, the lighting branch controller 1 sends the single control command to the six single light controllers 2 at the same time. After the sending is completed, the group control of the WSN network is realized.

Embodiment 2

[0080] like image 3 Shown is another implementation in which the WSN network is a tree-shaped network. The control system in this embodiment consists of a lighting branch controller 1 and six single-lamp controllers 2 . For extreme cases when only one child node is allowed per node, it is image 3 In the connection mode shown, the lighting branch controller 1 is connected to two single-lamp controllers 2 in sequence. The six single-lamp controllers 2 are respectively a first-level single-lamp controller, a second-level single-lamp controller, a third-level single-lamp controller, a fourth-level single-lamp controller, a fifth-level single-lamp controller and a sixth-level single-lamp controller. light controller.

[0081] In order to realize the group control command of LeafNode1-LeafNode6, the command transmission times of the existing control method between point to point is: "path 1"+("path 1"+"path 2")+("path 1"+" Path2" + "Path3") + ("Path1" + "Path2" + "Path3" + "Pat...

Abstract

The invention discloses a wireless sensor network (WSN)-based illumination monitoring system which comprises a lighting branch circuit controller, and a plurality of single-lamp controllers which are arranged on street lamps, wherein the lighting branch circuit controller is connected with the single-lamp controllers in a tree networking mode, namely the lighting branch circuit controller is connected with a plurality of first-grade single-lamp controllers, each first-grade single-lamp controller is connected with a plurality of second-grade single-lamp controllers, each second-grade single-lamp controller is connected with a plurality of third-grade single-lamp controllers, and the like, so that the tree networking connection mode of the lighting branch circuit controller and a plurality of grades of single-lamp controllers is formed. The invention also discloses an implementation method for a group control command of the illumination monitoring system. The communication distance between modules is shortened, and communication reliability of the system is improved; moreover, the high-efficiency group control command is adopted by the tree networking mode, so the occupation rate of network channels is greatly reduced and communication success rate is not less than 99 percent.

Description

technical field [0001] The invention relates to a WSN network-based urban lighting single-lamp monitoring system and a method for realizing group control commands of the system. Background technique [0002] The monitoring terminal of the urban lighting system is mainly composed of the lighting branch controller (BranchNode) and the single lamp controller (LeafNode), and forms a WSN network. The lighting branch controller is responsible for the establishment and maintenance of the entire WSN network, and the single lamp controller actively joins After the WSN network, the data transmission with the lighting branch controller can be realized. In practical applications, a power distribution cabinet monitored by a lighting branch controller generally consists of multiple branches, each branch has multiple street lights, and each street light is monitored by a LeafNode. [0003] The group control command, as the name implies, needs to be received by each single light controller...
