What does vehicle signal interruption mean?

[MacCali]

Vehicle signal interruption refers to the complete or partial interruption of wireless communication and satellite positioning signals installed on buses, rendering them unusable. Below is relevant information about satellite positioning systems and interrupt numbers: 1. Satellite positioning system: A satellite positioning system is a technology that uses satellites to accurately locate objects. It has evolved from initially low positioning accuracy, inability to provide real-time positioning, and difficulty in offering timely navigation services to today's high-precision GPS global positioning system. This system enables the observation of four satellites simultaneously at any time and any point on Earth to achieve functions such as navigation, positioning, and time synchronization. 2. Interrupt number: An interrupt number is a code assigned by the system to each interrupt source for identification and processing. Interrupt numbers play a crucial role in the interrupt handling process. In interrupt systems that use vector interrupt methods, the CPU must rely on them to locate the entry address of the interrupt service routine and achieve program transfer.
