However, the electronic monitoring equipment on existing logistics vehicles mainly has the following two shortcomings: First, existing vehicles The interconnection between electronic devices on the Internet is mainly through bus technology. Needless to say, the advantages of using bus technology, but one thing that cannot be ignored is that the use of bus technology requires wiring. Since most logistics vehicles have long bodies, if the layout is long The line is not only troublesome but also increases the possibility of the line cable being cut off, which reduces the reliability of the line. For example, the vehicle body of the reversing radar is long; It is useless, such as the monitoring of tire pressure and tire temperature; in the case of multi-point environmental monitoring and the monitoring node will change the type and position according to the monitored object, wiring operation is also a very headache, such as the compartment cargo Multi-point monitoring of the environment. Second, the degree of integration is low. The functions of the automotive electronic systems on today's logistics and transportation vehicles are relatively single. Where there is an on-board electronic lock system, there may be no on-board navigation system, reversing radar system, and tire pressure monitoring system. There may be no WIFI network in places where there is RFID radio frequency identification, and there is no entertainment camera and other functions in places with RFID radio frequency identification.
