It is very common to change trailers in 3-5 minutes. On the one hand, this facilitates the circulation of vehicles. On the other hand, it poses a serious problem to the logistics of bulk goods, especially the increased safety risks of bulk goods along the way for high value-added bulk goods. It is more convenient to switch goods along the way, and stealing and changing goods happen from time to time, which puts higher requirements on the supervision of goods along the way. How to do a good job of road supervision is a difficult problem for every supervisor, so a monitoring device and system for separating the front of a car and the trailer is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a monitoring device and system for the separation of a vehicle head and a trailer. The present invention establishes a Lora communication between a first Lora unit and a second Lora unit on the head and the body. The first Lora unit on the body transmits a heartbeat packet to the second Lora unit on the head every minute. If the second Lora unit on the head fails to receive the heartbeat packet for 6 minutes, it is considered that the head is separated from the trailer. The Beidou / GPS unit on the head triggers an alarm message to the server of the monitoring end, and the alarm information is stored. The staff can connect to the server through a PC or an intelligent terminal to view the information of each monitoring point. When an abnormal situation occurs, the server sends the abnormal information to the staff's intelligent terminal or PC by early warning, which is convenient for the staff to quickly verify and troubleshoot the abnormal situation.
