Wireless Truck Repeater Network-Based Tire Pressure Monitoring System (6–48 Wheels) Supports Automatic Swap-and-Haul With Multiple Trailers

Wireless Truck Repeater Network-Based Tire Pressure Monitoring System (6–48 Wheels) Supports Automatic Swap-and-Haul With Multiple Trailers

I. Product Overview

The Truck Network-Based Tire Pressure Monitoring System with Wireless Repeaters is a network-based direct TPMS developed for heavy-duty trucks and semi-trailer tractor-trailer combinations. It employs a wireless signal relay and forwarding solution, eliminating the need to install communication cables between the tractor and trailer. This addresses the pain points of weak tire pressure signal transmission in traditional trailer systems and the cumbersome wiring required when swapping trailers. The system complies with the JT/T 1429 standard for tire pressure monitoring in commercial vehicles. It collects real-time tire pressure and temperature data, relays the signals over long distances via the wireless repeater, and uploads the data to the in-vehicle terminal. It supports both local display and remote platform monitoring, is suitable for multi-axle and long trailer combinations, and can be adapted for both factory installation on new vehicles and retrofitting of existing trucks.

II. System Components

1. Tire Sensors: Installed on each wheel, these sensors collect real-time tire pressure and temperature data and periodically transmit wireless sensor data. They support multiple wheel sets on trucks and trailers.
2. Wireless Repeater: The core component of this system, it wirelessly receives signals from the tire sensors, amplifies them, and relays them forward. No communication wiring is required between the tractor and the trailer, and there is no need to reconnect communication cables when the trailer is replaced.
3. On-Board TBOX / In-Vehicle Display Terminal: Receives tire pressure data relayed by the repeater, displays tire pressure and temperature locally in real time, and provides audible and visual alerts; simultaneously uploads vehicle tire data to the cloud monitoring platform.
4. Cloud Monitoring Platform: Aggregates tire pressure monitoring data from multiple vehicles, supports remote fleet monitoring, historical data storage, and fault log export, enabling digital tire safety management for fleets.

III. Core Features

1. Real-Time Monitoring: Continuously collects tire pressure and temperature data from all vehicle tires; data is reliably transmitted via the wireless relay to the in-vehicle terminal for real-time visual display.
2. Multi-Level Alerts: Supports high-pressure, low-pressure, rapid deflation, and high-temperature alerts, with audible and visual notifications on the terminal and simultaneous reporting to the cloud; alert thresholds can be customized based on vehicle model.
3. Wireless Relay Signal Transmission: Signals from trailer sensors are wirelessly relayed via the repeater, eliminating the need for communication cables between the tractor and trailer. No rewiring is required when attaching or swapping trailers.
4. Automatic Trailer Recognition: After a trailer is replaced, the repeater automatically recognizes the trailer’s sensors, eliminating the need for manual rewiring or pairing and improving trailer-switching efficiency.
5. Data Upload to the Cloud: Tire pressure, alerts, and historical records are uploaded to the cloud platform via the TBOX, allowing fleets to remotely monitor the tire status of the entire vehicle and trace fault history.
6. Low-Power Management: Sensors and the repeater feature a sleep-wake mechanism; they automatically wake up when the vehicle is in motion and enter low-power standby mode when parked, extending the service life of the sensors.

IV. Product Advantages

1. No Communication Wiring Harness—Simple Installation and Maintenance: Eliminates communication cables between the tractor and trailer, preventing failures caused by wire wear, strain, or breakage, and saving time and effort during trailer installation, removal, and swapping.
2. Stable Long-Range Wireless Transmission: The wireless repeater amplifies signals, resolving signal attenuation issues in long trailers and multi-axle vehicles, ensuring reliable transmission of tire data from the rear of the trailer.
3. Compatibility with Multiple Trailers and Quick Switching: No wiring or debugging is required when switching trailers; the repeater automatically matches the trailer’s sensors, improving fleet turnaround efficiency.
4. Suitable for Both Factory Installation and Retrofit: It can serve as a standard factory-installed solution for truck manufacturers or be used to retrofit existing heavy-duty trucks and semi-trailers, offering strong compatibility.
5. Connected Digital Management: Data is uploaded to the cloud, supporting batch management of fleets, assisting with tire maintenance, reducing the risk of tire blowouts, and minimizing downtime losses.
6. High Compliance: Meets regulatory standards for tire pressure monitoring in commercial vehicles, as well as annual inspection and safety monitoring requirements for freight vehicles.

V. Application Scenarios

1. Heavy-duty trucks and semi-trailer tractor combinations for long-haul trunk logistics;
2. Heavy-duty freight trailers operating within ports, mining areas, and industrial parks;
3. Semi-trailer fleets for express delivery, expedited freight, and hazardous materials transport;
4. Digital safety upgrade projects for fleets of freight companies and logistics groups;
5. Factory-installed equipment projects for truck and trailer manufacturers.
