What does 'OBU has been dismantled' mean?

OBU has been dismantled means that the OBU device has been removed or moved by the user without authorization, resulting in the OBU becoming ineffective. Concept of OBU: OBU stands for On-Board Unit, which is a microwave device that communicates with RSU. In the ETC system, the OBU is placed in the vehicle, while roadside units (RSU) are installed along the road, and they communicate with each other via microwave. When a vehicle passes the RSU at high speed, they communicate via microwave to verify authenticity, identify the vehicle type, calculate the toll rate, and deduct the toll fee. Limitations of OBU: The in-vehicle application environment is quite harsh, so the performance requirements for in-vehicle equipment are higher than those for general electronic devices. When designing an intelligent transportation system, it is particularly important to consider the application environment to ensure that the system can adapt to the in-vehicle environment and utilize it to create greater value than general systems.

As a frequent driver, I've encountered similar situations myself. 'OBU removed' means the onboard toll collection device was taken off, possibly during maintenance or upgrade operations. That time my car's OBU kept alarming due to looseness, so I tried removing it to check the issue, only to find the battery was drained. The biggest hassle after removal was having to pay manually at toll stations - queuing wasted time and easily distracted me from driving safely. After some trial and error, I bought new batteries and reinstalled it myself. The process was straightforward but required care not to damage the connectors. Regular checks on mounting screws can prevent vibration-induced detachment and accidental removal. For frequent highway users, maintaining OBU functionality saves time, effort and peace of mind.

I'm quite fascinated by the electronic gadgets in cars, and OBU removal refers to detaching the On-Board Unit device from the vehicle. This device is responsible for communicating with the ETC system. After removal, the car won't automatically deduct toll fees when passing through, possibly requiring cash or QR code payments instead. I once removed mine to upgrade the firmware, and upon opening it, I found some chips and antennas inside, which was quite interesting. However, it's important to disconnect the power cable during the operation to prevent short circuits and sparks. Beginners are advised to refer to the manual or seek professional help for removal. When not in use, it's recommended to store it in a cool place away from direct sunlight to extend the battery life. A related topic is that with the increasing number of onboard electronic devices nowadays, maintenance should keep up and not be neglected.

My driving principle is safety first. OBU removal means the device has been detached, which could be due to malfunction or human error, resulting in ETC failure at toll gates and requiring manual processing that increases safety risks. Once, I witnessed a friend's post-removal toll station congestion with high accident rates, so I warned him not to attempt it again. I recommend regularly checking battery status and ensuring secure installation—smooth driving matters most; don't let minor issues cause major problems.
