As highway and expressway toll collection systems evolve toward digitalization and intelligence, the communication network’s high reliability, real‑time performance, and security have become core requirements. Drawing on over 15 years of expertise in industrial communications, MRD delivers full‑scenario, highly resilient industrial Ethernet solutions for toll collection systems – ensuring efficient, lossless, and secure data transmission from lane to center.
Industry Challenges: Three Pain Points of Traditional Toll Communications
Cybersecurity Challenges
Frequent data interaction between lanes and toll stations and hearts, susceptible to network storms, illegal access, etc.Environmental Adaptation Challenges
Toll stations and road cabinets face high and low temperatures, dust, and EMI, making it difficult for ordinary switches to operate stably for a long time.O&M Efficiency Challenge
It is difficult to locate the faults of terminal equipment (such as fee display, railing machine), and there is a lack of effective remote management and environmental monitoring methods.
Needle for semi-automatic and non-stop charging two mainstream scenarios, we provide customized industrial Ethernet networking solutions to ensure the robustness of each level of the network.
Program features:The TCC4100 series access switch is deployed in each lane control cabinet. passes industrial ring network redundant technology, lane data is gathered to the toll station switch, and then the passes Gigabit backbone is transmitted to the distraction and the heart.
Customer ValueEven if the single point link is broken, the ring network can resume communication in 20ms to ensure that the toll flow data is not lost and the transaction processing is continuous.
Program features:The needle for etc gantry system and lane system strengthens the Layer-3 switching function, effectively isolates the broadcast domain, and prevents network storms from affecting the core business.
Customer ValueEnsure RSU (roadside unit) and control the low-when and high-security transmission of massive transaction data between the hearts, supporting high-speed passage and accurate billing.
Core products: TCC4100 series - dedicated for transportation scenario design access to industrial switch
TCC4100 is MRD dedicated to transportation toll collection, road monitoring, etc. The scenario creates a high-performance terminal access device, whose interface and function design closely follow the operation and maintenance pain points:
| key characteristics | TECH SPECS | bringing value to the for transportation industry |
|---|---|---|
| Layer-3 Switching Capabilities | Support static routing and VLAN isolation | Eliminate cyber storms, improve network security, and ensure that charging services are prioritized |
| Rich Interface Portfolio | 4 Gigabit/Fast EthernetSFPfiber port +8 Gigabitcopper port +4 serial port | Flexible access to a variety of terminals (license plate recognition, railings, fee display) |
| Intelligent I/O Interface | Supports 4 DI +4 DO | Remotely restart the crash terminal, when the alarm cabinet door is illegally opened, reducing on-site processing |
| Environmental monitoring interface | Supports 1 temperature and humidity sensor interface | On-demand access to sensors, real-world when monitoring the cabinet microenvironment, to prevent high-temperature downtime |
MRD Product Advantage: Derived from a deep understanding of the quality of this for industry
We not only provide products, but also deliver long-term stable operation certainty. This certainty stems from the rigorous handling of every detail of our for product design:
Thermal design: clearly distinguish the advantages and disadvantages of fan suction and blowing in different scenarios to ensure long-term Thermal efficiency.
protection process: Using conductive oxidation and EniG plating, for significantly improves corrosion resistance and signal transmission performance compared to ordinary paint and tin plating.
Network transformer: Multi-port network transformer is selected to optimize PCB layout, improve port isolation and surge protection capability.
Power and software: The power supply isolation scheme is adopted to resist the interference of Power fluctuations; the firmware implantation software periodic memory check algorithm actively detects and repairs potential dangers.
Supports 24 Ethernet ports including 8×2.5G SFP; any two ports can form a self-healing ring with multiple independent rings; QoS (IEEE 802.1p/1Q and ToS/DiffServ); SNMPv1/v2c/v3
