Description

Technical Field

[0001] The utility model relates to the technical field of highway equipment, in particular to a modular lane equipment control device for a highway. Background Art

[0002] Lane controllers are core equipment in highway toll collection systems and are widely used at toll booths. They connect lane industrial computers and external equipment, convert digital and electrical signals, and monitor and control I / O interface devices such as ground sensors, traffic lights, ceiling lights, alarms, and barriers, ensuring the smooth operation of lane services. Existing lane controllers generally use I / O protocols, resulting in limited functionality and inconvenient troubleshooting. These controllers fail to meet the demands of innovative lane toll collection systems and the need to enhance the intelligence of toll lane equipment.

The output module 24 completes the lifting and lowering of the barrier machine and the switching of the traffic signal light according to the instructions. Video network module 25 implements local area networking. Based on MAC address information, it forwards data packets from access devices such as ticket booth monitoring, lane monitoring, and hard disk recorders, and communicates with the upper-layer switch connected to the local area network. The module uses RS485 to synchronize the connection status of each network port to the main control module 21 via the communication baseboard 1. Audio module 26 collects voice information from connected devices through the input interface, amplifies it through internal circuitry, and then sends it to the output interface for output by the connected power amplifier, enabling intercom functions between the ticket booth and the monitoring room, and between the lane and the monitoring room.
