Parking space guidance controller for parking lot based on power line carrier communication

Abstract

The invention discloses a parking space guidance controller for a parking lot based on power line carrier communication, which comprises a display module, a control module, a power supply module, a data acquisition module, a heat dissipation module and a network communication module. The parking space guidance controller utilizes a power line carrier communication technology, can achieve data transmission of a parking space detector and a parking space guide screen by using a power cable, and has lower requirements for cable selection; the parking space guidance controller is high in equipmentintegration, and integrates a central controller, a node controller, a switching power supply and network communication equipment in an existing parking space guidance control box; the parking spaceguidance controller is provided with a display module and a control module, and can take various data required by a user according to requirements; the power supply module is provided with a voltage stabilization source, and can convert 220V civil electricity into DC 24V, thereby facilitating power supply of some modules; the parking space guidance controller is additionally provided with the heatdissipation module, so that the safety of power utilization is ensured; the equipment data supports flexile transmission of two media such as twisted-pairs and optical fibers; and various monitoringdata supports flexible checking of a local terminal and a mobile terminal, and the application prospect is wide.

Description

【Technical field】 [0001] The invention discloses a parking space guidance controller based on power carrier communication, which belongs to the field of intelligent instruments. 【Background technique】 [0002] With the development of smart buildings, the Internet of Things and computer information technology, more and more equipment and hardware products have been added to smart cities, and intelligence has gradually developed from a concept to a concept and reality. my country has a vast territory and a large population. With the development of the national economy and the improvement of people's living standards, private cars have gradually evolved from luxury goods to national mobility vehicles. At the same time, parking spaces in big cities have become extremely tight, the scale of parking lots has gradually expanded, and intelligent parking space guidance has emerged as the times require. [0003] At present, the mainstream parking guidance systems in the market are al...

Problems solved by technology

[0003] At present, the mainstream parking guidance systems in the market are all designed based on 485 communication technology. When laying cables, RVVSP2×1.0 (1.0mm caliber copper core PVC insulated shielded PVC sheathed stranded flexible cables must be used at the same time. 485 bus and CAN bus) and RVV2×1.0 (1.0mm caliber two-core copper core PVC insulated shielded PVC sheathed stranded flexible cable), cable procurement and equipment selection are complicated, and auxiliary equipment that needs to be installed on the bridge There are a lot of equipment, and the heat dissipation performance of the equipment is not considered. The instantaneous temperature of the relatively concentrated location of the cables may be high, which is not conducive to the safety of electricity use.
