Royal Freight, a shipping and transportation company in Texas, uses a wireless location system from ID Systems to track the location and status of its trailers across North America. The new system provides companies with visibility into the location of the trailer and its cargo. If the trailer is opened during transportation, the system will also send an alert. Moreover, the new system uses a more stable power supply.
This system combines VeriWise technology-originally belonging to GE’s Intelligent Asset Solutions Division, acquired by ID Systems in January this year. Each VeriWise sensor device stores a unique ID code, which corresponds to the trailer data on the company’s back-end server. The system also contains a set of GPS equipment to track the position of the trailer. A CDMA cellular transmitter sends the ID code and position to the cellular signal tower at specific intervals. Royal Freight hopes that this new system will help the company obtain a more detailed location of each trailer-when they are transported by the company’s haul truck or a third-party transportation provider. In addition, the company also hopes to use the system to improve the safety of trailer cargo (usually consumer goods, and raw materials and components required on time).
For the past seven years, Royal Freight has been using another manufacturer’s wireless satellite tracking solution to closely monitor the locations of trailers across North America. Without such a system, the company would not be able to obtain visibility of the location of empty trailers, and would often face the situation where idle trailers pile up in the yard, while on the other hand there is a shortage of trailers in other locations.
The first trailer tracking program adopted by Royal Freight helps the company better understand the location of vehicles and reduce the number of trailers in a certain area. However, as time goes by, some devices cannot work properly due to exhausted batteries, and the cost of replacing them is too high. In addition, he said that in addition to tracking the location of the trailer, the company hopes to better understand whether the trailer door has been opened during transportation.
The sensor on the front of the trailer detects the presence of cargo
When truck drivers park their cars in parking lots or on the side of the road, freight trailers are often the target of thieves, especially at night. The thief will enter the trailer and steal part of the goods. When the driver continues to transport the next day, he will not notice that the goods have been stolen. The safety problem is even more serious when the tow is transported by a third-party carrier.
VeriWise technology solves the battery problem of the old system while also providing safety confirmation. The size of the equipment is 10*12 inches, connected to a 7*3 inch solar panel, and installed at the front of the trailer. The solar panel can charge the battery of the device, thus providing a continuous power supply. This system can be used for the entire life cycle of the trailer without replacement, said Darryl Miller, COO of ID Systems’ Intelligent Assets Department. If the system’s motion detector senses that the trailer has been stationary for two weeks, he said, the device can enter a power-saving mode, prolonging the signal transmission interval. If the device is not within the signal range, the data will be automatically stored until it reaches the signal again.
For safety reasons, the device is wired to a sensor on the trailer door. If someone breaks the door or unlocks the door, the sensor detects the behavior and sends a notification along with the ID code and location of the device to the software. The software stores the data and then sends an alert to notify the relevant parties, such as Royal Freight management. A cargo sensor is also installed at the front of the trailer, which uses ultrasound to determine whether the object is loaded. The VeriWise package then sends the loading or unloading data, and the state change time.
All information, including the location of the trailer, is sent to a web server in XML form and can be obtained through Royal Freight’s existing management system.
In January of this year, Royal Freight began to remove the old system and install the new system for all 1,500 trailers.
Head has seen the advantages of the wireless trailer tracking system. The company has greatly improved the utilization rate of trailers and ensured the safety of goods.
