This system is a standalone TPMS (Tire Pressure Monitoring System) specifically designed for tractor-trailer combinations. It utilizes a 433MHz wireless communication architecture, requiring neither 4G nor a cloud platform. Its key feature is the simultaneous display of tire data for the tractor and all trailer tires on a single screen in the cab.

Automotive-grade sensors collect tire pressure and temperature data from each tire on the tractor and trailer, transmitting it wirelessly to the cab display unit. Drivers can view the status of all tires on the entire vehicle (tractor + multiple trailers) at a glance from inside the cab, with local audible and visual alarms triggered in case of abnormalities.

The sensors support multiple installation methods, feature controllable airtightness and service life, and are resistant to vibration and extreme temperatures, making them suitable for long-haul drop-and-hook freight operations. This system is ideal for customers who do not require remote cloud monitoring but simply need the driver to view the status of all tires on the tractor and trailer at a glance from the cab.

• Automotive-Grade Tire Pressure Sensors Optional built-in strap-on or valve-mounted sensors are installed on the tractor and trailer tires, respectively, to collect tire pressure and temperature data, which is transmitted wirelessly at 433 MHz.
• In-Vehicle Display Unit (Single-Screen Display) The core receiving terminal that simultaneously receives signals from all sensors on both the tractor and trailer; displays tire pressure and temperature for all tires on a single screen at once. Supports audible and visual alarms, sensor ID learning and binding, customizable tire positions, alarm threshold settings, and configuration retention during power outages.
• Wireless Repeater (Optional) Optional for scenarios where the trailer is at a considerable distance or signal attenuation is severe; used to amplify the wireless signals from the trailer's sensors, ensuring stable transmission of trailer data back to the cab display.
• Installation Accessories Vehicle power cable, mounting brackets, seals, sensor mounting hardware, adapters, cable ties, etc.

• Simultaneous Display of Tractor and Trailer Tires on a Single Screen: The cab display shows the tire pressure and temperature of all tires on both the tractor and trailer simultaneously on a single screen, eliminating the need to switch screens to view trailer tire data.
• Local Audible and Visual Alerts: The display issues audible and visual alerts when any tire experiences high or low pressure, rapid air loss, overheating, sensor disconnection, or low battery.
• Sensor ID Learning and Pairing: Supports learning sensor IDs one by one; tire position numbers can be customized. Re-pairing is possible after swapping trailers during drop-and-hook operations.
• Independently Customizable Alarm Thresholds: High-pressure, low-pressure, and high-temperature alarm thresholds can be set separately for the tractor and trailer tires to accommodate different load conditions.
• Sensor Health Self-Test: Monitors sensor battery levels and signal connectivity in real time, providing early warnings of potential sensor failure.
• Power-Off Parameter Retention: After the vehicle is turned off and power is disconnected, sensor pairing information, alarm thresholds, and alarm logs are preserved and automatically restored when power is restored.
• Enhanced Signal Relay (Optional): Adds a wireless repeater to boost the trailer's wireless signal over long distances and reduce packet loss.

• Single-Screen Global Visualization: Displays tire data for both the tractor and trailer on a single screen. Drivers can monitor the safety status of all tires at a glance without scrolling or switching screens, enhancing driving safety.
• Standalone Operation: Requires no 4G network or cloud platform, eliminating annual platform fees and reducing project investment costs.
• Automotive-Grade Sensors: Controlled airtightness and lifespan ensure strong long-term stability, making them suitable for the bumpy conditions and extreme temperatures encountered on long-haul routes.
• Compatible with Swap-and-Haul Operations: Supports pairing the tractor with different trailers; sensors can be quickly re-paired after a trailer change.
• Optional Wireless Relay: Adds a relay for scenarios with long trailers or weak signals to ensure stable reception of tire signals from the trailer.
• Wide Voltage Input: Adaptable to voltage fluctuations in commercial vehicles, ensuring stable onboard power supply.
• Simple Installation and Maintenance: Simple overall structure with few potential failure points, resulting in minimal maintenance effort.

• Tractor-Trailer Combinations for Long-Haul Logistics: Long-distance highway drop-and-hook freight transport for individual truck owners and small fleets that do not require remote cloud-based management.
• Refrigerated Trailers, Box Trailers, and Tank Trailers: Various tractor-trailer combinations for freight transport.
• Short-Haul Transfer Tractor-Trailer Combinations: For towing trailers within factory grounds and port yards.
• Customer Needs: Freight fleets where drivers want to view all vehicle tires at a glance from the cab and prefer not to switch screens frequently to check trailer tire pressure.
