specific Embodiment approach

[0034] like image 3 As shown, the present invention adopts an improved token bus technical scheme when dealing with multiple nodes sharing communication channels, and provides equal network access services for each node, with high reliability, high communication rate, and determinable network performance. Guarantees the requirements of equipment monitoring for transmission delay. The specific implementation is as follows:

[0035] 1) After the system is powered on, the modems on the bus conduct ad hoc networking through power lines, and each node has a unique logical address after networking. Each node has a predecessor address and a successor address, as well as the master node address.

[0036] 2) When the network is idle, only idle tokens flow continuously on the ring.

[0037] 3) After the system is powered on, the initial idle token is issued by the master node, and after traversing all the slave nodes, the last slave node is passed to the master node.

[0038] 4) Wh...

Abstract

The invention discloses a monitoring device utilizing a power line carrier technology and a monitoring method thereof. The monitoring device utilizing the power line carrier technology and the monitoring method thereof are used for solving the problems of high wiring difficulty, maintaining difficulty and transmission rate limitation of a traditional field bus device monitoring system in a closed space application background. According to the method, a traditional token bus network technology is innovated, the improved token bus technology is applied to the power line carrier technology, a self-organization of a token LAN is carried out by a modem on a bus after the system is electrified, and an equal network access service is provided for each node. According to the monitoring device utilizing the power line carrier technology and the monitoring method thereof, the problem that a network time delay is unpredictable when CSMA / CA is used for processing a channel access mechanism in the traditional power line carrier technology is solved, high reliability and high communication rate are achieved, and requirements of device monitoring for data transmission reliability are satisfied. According to the invention, many-to-one device monitoring is realized through the power line carrier technology.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a monitoring device and a monitoring method using the power line carrier technology. Background technique [0002] The monitoring system of communication equipment is of great significance to ensure a reliable communication link. Since the 1980s, fieldbus has been widely used in industrial automation control because of its advantages of strong reliability, fast communication and wide compatibility. At present, there are various equipment monitoring management systems and fieldbus equipment, which can meet the needs of various industries. However, in some application scenarios with limited space, fieldbus technology also has problems such as high wiring difficulty, limited transmission rate, and difficult maintenance. [0003] Power line carrier technology refers to a communication method that uses the existing distribution network as a transmission medium for ...
