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.
