詳細(xì)介紹

The node controller is the middle layer of the three-layer network bus of the parking lot guidance system, and plays an important role in ensuring the safety, reliability and efficiency of the system. It is used for group management of the detectors, to realize the optimized management of network communication, and to ensure the safety of the system; to cyclically detect the status of the detectors under its jurisdiction, and to transmit relevant information to the central controller.
The node controller is used to connect the central controller and the parking space detector, display screen, guide arrow, etc.
The node controller mainly solves the problem of unreliable communication caused by long distance, the problem of network node expansion, and the problem of group management.
The controller uses RS485 communication port, can communicate with a variety of equipment, suitable for multi-equipment parking lot network.
