Museum intelligent explanation system based on visible light and power line carrier communication

Abstract

The invention discloses a museum intelligent explanation system based on visible light and power line carrier communication. The museum intelligent explanation system comprises a remote central control service platform, at least one power network bridge, a plurality of power line carrier communication control modules, a plurality of user visible light information mobile devices and a plurality of node terminal control modules which are arranged on corresponding cultural relic exhibiting information points. The central control service platform is respectively connected with the power network bridges through a low voltage distribution power circuit to achieve two-way transmission of data, each power network bridge is connected with the power line carrier communication control modules through the low voltage distribution power circuit to achieve two-way transmission of the data, and the power line carrier communication control modules are connected with the corresponding node terminal control modules to achieve two-way transmission of the data. The museum intelligent explanation system not only can meet LED lighting requirements of a museum, but also can use the existing low voltage distribution power circuit to perform communication control, and voice explanation information is transmitted and controlled in real time.

Description

technical field [0001] The invention relates to an intelligent explanation system for a museum exhibition hall based on visible light and power carrier communication, and belongs to the technical field of short-distance wireless communication and the technical field of power line carrier wired communication. Background technique [0002] At present, with the rapid advancement of Internet of things (Internet of things) technology and industry, the dream of information exchange anytime and anywhere is gradually being realized. The Internet of Things relies on short-distance communication technologies such as Wireless Sensor Network (WSN) and RFID (Radio Frequency Identification), as well as infrastructure such as mobile communication networks and the Internet. Short-distance communication uses radio wave communication. Although this method has been widely used, it has many defects such as harm to the human body, communication equipment is prone to mutual interference, and ...

Problems solved by technology

[0007] The disadvantage of the above-mentioned existing technical solutions is that, in the complex relatively long-distance low-voltage power line communication configuration scenario, during the communication process using the low-voltage power distribution line, the relative distance is relatively long or after the power distribution device, effective communication In the long-distance power line transmission of signals, communication failure or data loss is bound to occur, which will affect the reliability of system communication

This way of explaining cultural relics has brought a lot of inconvenience to users, and it has also brought a lot of trouble to the management and maintenance of museum explaining equipment.

In addition, the general museum is a multi-storey building, the 220V low-voltage power distribution line is relatively complex, and the power distribution line interface socket is relatively far away. If the direct power line carrier communication scheme is used, the data communication may be unreliable
